Abstract: The purpose of this study was to determine the prognostic value of the Geriatric Nutritional Risk Index (GNRI) in patients with upper tract urothelial carcinoma (UTUC) after radical nephrectomy (RNU). A retrospective study of UTUC patients was conducted at West China Hospital between May 2016 and June 2019. The optimal cut-off point for GNRI was determined using the X-Tile procedure. Univariate and multivariate analyses were performed to identify predictors, and two- and four-year cancer-specific survival (CSS) prediction nomograms were created based on the results of the multivariate analyses. Furthermore, time-dependent ROC curve, calibration curve and decision curve analyses were conducted. A total of 219 patients with UTUC following RNU were identified and subsequently divided into three groups based on the critical values of GNRI (91.2, 98.8). GNRI was identified as a significant risk factor for CSS, with patients exhibiting higher GNRI demonstrating elevated CSS (hazard ratio = 0.58; 95% confidence interval, 0.32-0.92; P = 0.037). Furthermore, the GNRI-based nomogram demonstrated high predictive capacity for CSS, with areas under the curve of 0.810 and 0.842 for 2- and 4-year CSS, respectively. Preoperative GNRI is an independent predictor for CSS in UTUC patients who underwent RNU and should be considered as a promising personalized tool for clinical decision-making.<br/>Copyright © 2025.

Association between Geriatric Nutritional Risk Index and survival outcomes in patients with urological cancers: an updated meta-analysis

Mon, 17 Feb 2025 00:00:00 +0000

BMJ Open. 2025 Feb 17;15(2):e091639. doi: 10.1136/bmjopen-2024-091639.

ABSTRACT

OBJECTIVES: This meta-analysis aimed to evaluate the association between the Geriatric Nutritional Risk Index (GNRI) and survival outcomes in patients with urological cancer.

DESIGN: Systematic review and meta-analysis of observational studies.

DATA SOURCES: A comprehensive literature search was conducted in Medline, EMBASE, Google Scholar and the Cochrane Library from inception to 7 July 2024.

ELIGIBILITY CRITERIA: Studies were included if they examined the correlation between the GNRI and long-term survival outcomes in adult patients (≥18 years old) with urological cancers.

DATA EXTRACTION AND SYNTHESIS: Two researchers independently extracted data and assessed study quality using the Newcastle-Ottawa Scale and certainty of evidence using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) methodology. Publication bias was evaluated using funnel plots and Egger's test for outcomes with more than 10 studies. Pooled HRs and 95% CIs were calculated using a random-effects model. Subgroup analyses, meta-regression and sensitivity analyses were performed.

RESULTS: 17 studies involving 8816 patients were included. Study quality assessment showed that 15 studies had a low risk of bias (scores 7-9) and two had a high risk (scores 5-6). Low GNRI was significantly associated with poor overall survival (OS) (HR: 2.6, 95% CI: 2.0 to 3.38, p<0.00001, I² = 64%, 13 studies), cancer-specific survival (CSS) (HR: 2.65, 95% CI: 1.76 to 3.98, p<0.00001, I² = 75%, 7 studies), recurrence-free survival (RFS) (HR: 1.47, 95% CI: 1.02 to 2.1, p=0.04, I² = 58%, four studies) and progression-free survival (PFS) (HR: 1.86, 95% CI: 1.54 to 2.23, p<0.00001, I² = 0%, five studies). Funnel plot and Egger's test (p=0.948) indicated a low risk of publication bias for OS. GRADE assessment showed low certainty of evidence for OS and PFS, and very low certainty for CSS and RFS. Meta-regression identified follow-up time and sample size as significant sources of heterogeneity.

CONCLUSIONS: A low GNRI is significantly associated with poor survival outcomes in patients with urological cancer. The GNRI may serve as a valuable prognostic tool in clinical practice. Further research is needed to validate these findings in diverse populations and to explore the underlying biological mechanisms.

The Role of Maintaining Nutritional Adequacy Status and Physical Activity in Onco-Nephrology: Not a Myth Anymore, but a Reality

Sat, 25 Jan 2025 00:00:00 +0000

Nutrients. 2025 Jan 17;17(2):335. doi: 10.3390/nu17020335.

ABSTRACT

Background: Physical Activity (PA) provides numerous biological and psychological benefits, especially for cancer patients. PA mitigates treatment side effects, influences hormones, inflammation, adiposity, and immune function, and reduces symptoms of anxiety, depression, and fatigue. This study evaluates the impact of PA on these positive outcomes. Materials and Methods: An observational retrospective study enrolled 81 patients: 31 with CKD stages II-V and 50 with CKD and urological malignancies. Baseline and 6-month follow-up visits included clinical (Iohexol, Creatinine, Cystatin C) and anthropometric parameters (Bioimpedance Analysis, body circumferences). Physical activity levels were assessed using the Rapid Assessment of Physical Activity (RAPA) test. Patients followed a Mediterranean-like diet with controlled protein intake (MCPD) and received PA improvement advice. Statistical analysis was performed using linear regression and Pearson's Chi-Squared test with R programming. Results: Significant reductions in total adiposity and abdominal fat and improved body fluid distribution were observed. Post intervention, there was a 25.4% reduction in inactive individuals and an 88% increase in active lifestyles. Patients aged 75+ were more likely to be sedentary, indicating a need for increased professional attention. No correlation was found between increased PA and creatinine, cystatin, and eGFR values, but a positive correlation with GFR measured by iohexol clearance remained significant in multivariate analysis. Post intervention, regular PA engagement increased from 12.3% to 48% (p < 0.002). Conclusions: Incorporating PA and nutritional assessments into standard clinical care, supported by a collaborative nephrologist-nutritionist approach, can enhance the quality of life of CKD patients.

Prognostic Significance of the Controlling Nutritional Status (CONUT) Score in Patients with Muscle-Invasive Bladder Cancer after Radical Cystectomy

Wed, 20 Nov 2024 00:00:00 +0000

Urol J. 2024 Nov 27;21(6):390-396. doi: 10.22037/uj.v21i.8266.

ABSTRACT

PURPOSE: To assess the impact of the The Controlling Nutritional Status (CONUT) score, an indicator of nutritional status, on the survival and prognosis after radical cystectomy.

MATERIALS AND METHODS: The medical records of patients who underwent consecutive radical cystectomy operations with the diagnosis of muscle-invasive bladder cancer at our clinic were retrospectively examined. The patients were separated into two groups based on the cut-off CONUT score which was derived using the receiver operating characteristic (ROC) curve. The group with a CONUT score ≥ 3 was categorized as high CONUT, whereas the group with a CONUT score < 3 was categorized as low CONUT. The groups were compaired according to oncological outcomes and survival risk factors.

RESULTS: Cancer-specific survival (CSS) and overall survival (OS) were statistically significantly lower in the High CONUT group compared to the Low CONUT group (p < 0.001, p = 0.024, respectively). Age (HR: 1.02, 95% CI: 1.006-1.04, p = 0.011) and CONUT score (HR: 3.92, 95% CI: 2.66-5.77, p < 0.001) were revealed to be independent prognostic variables in the multivariate analysis for OS.

CONCLUSION: The CONUT score was found to be an independent predictor of survival in patients with muscle-invasive bladder cancer in this study.

Predicting the prognosis of patients with renal cell carcinoma based on the systemic immune inflammation index and prognostic nutritional index

Thu, 24 Oct 2024 00:00:00 +0000

Sci Rep. 2024 Oct 23;14(1):25045. doi: 10.1038/s41598-024-76519-2.

ABSTRACT

The aim of the study was to analyze and discuss the value of preoperative systemic immune inflammation index (SII) and prognostic nutritional index (PNI) in predicting the prognosis of patients with renal cell carcinoma (RCC) after operation, and to establish a nomogram prediction model for patients with RCC after operation based on SII and PNI. From January 2014 to December 2018, 210 patients with RCC who underwent surgical treatment at the Xuzhou Central Hospital were selected as the research object. The receiver operating characteristic curve (ROC) was used to determine the optimal cut-off value for preoperative SII, PNI, LMR, PLR, NLR and the patients were divided into groups according to the optimal cutoff values. The survival rate of patients was evaluated. The risk factors that affect the prognosis of patients with RCC were determined by LASSO and Cox regression analysis, and a prognostic nomogram was constructed based on this result. The bootstrap method was used for internal verification of the nomogram model. The prediction efficiency and discrimination of the nomogram model were evaluated by the calibration curve and index of concordance (C-index), respectively. The average overall survival (OS) of all patients was 75.385 months, and the 1-, 2-and 3-year survival rates were 95.5%, 86.6% and 77.2%, respectively. The survival curve showed that the 5-year OS rate of low SII group was significantly higher than that of high SII group (89.0% vs. 64.5%; P < 0.05), and low PNI group was significantly lower than those in high PNI group (43.4% vs. 87.9%; p < 0.05). There were significant differences between preoperative SII and CRP, NLR, PLR, LMR, postoperative recurrence, pathological type and AJCC stage (P < 0.05). There were significant differences between preoperative PNI and BMI, platelet, NLR, PLR, LMR, postoperative recurrence, surgical mode and Fuhrman grade (P < 0.05). The ROC curve analysis showed that the AUC of PNI (AUC = 0.736) was higher than that of other inflammatory indicators, followed by the AUC of SII (0.718), and the difference in AUC area between groups was statistically significant (P < 0.05). The results from multivariate Cox regression analysis showed that SII, PNI, tumor size, tumor necrosis, surgical mode, pathological type, CRP, AJCC stage and Fuhrman grade were independent risk factors for postoperative death of patients with RCC. According to the results of Cox regression analysis, a prediction model for the prognosis of RCC patients was established, and the C-index (0.918) showed that the model had good calibration and discrimination. The subject's operating characteristic curve indicates that the nomogram has good prediction efficiency (the AUC = 0.953). Preoperative SII and PNI, tumor size, tumor necrosis, surgical mode, pathological type, CRP, AJCC stage and Fuhrman grade are closely related to the postoperative prognosis of patients with renal cell carcinoma. The nomogram model based on SII, PNI, tumor size, tumor necrosis, surgical mode, pathological type, CRP, AJCC stage and Fuhrman grade has good accuracy, discrimination and clinical prediction efficiency.

The role of preoperative immunonutrition on morbidity and immune response after cystectomy: protocol of a multicenter randomized controlled trial (INCyst Trial)

Wed, 16 Oct 2024 00:00:00 +0000

Trials. 2024 Oct 17;25(1):687. doi: 10.1186/s13063-024-08536-5.

ABSTRACT

INTRODUCTION: Cancer, malnutrition, and surgery negatively impact patient's immune system. Despite standardized surgical technique and the development of new perioperative care protocols, morbidity after cystectomy remains a serious challenge for urologists. Most common postoperative complications, such as infections and ileus, often lead to longer length of stay and worse survival. The immune system and its interaction with the gut microbiota play a pivotal role in cancer immunosurveillance and in patient's response to surgical stress. Malnutrition has been identified as an independent and modifiable risk factor for both mortality and morbidity. Immunonutrition (IN) may improve the nutritional status, immunological function, and clinical outcome of surgical patients. Aims of the study are (1) to evaluate the impact of IN on morbidity and mortality at 30 and 90 days after cystectomy and (2) to determine immune and microbiota signature that would predict IN effect.

METHODS: This is a randomized, multicentric, controlled, pragmatic, parallel-group comparative study, supported by the Swiss National Science Foundation. A total of 232 patients is planned to be enrolled between April 2023 and June 2026. Three participating centers (Lausanne, Bern, and Riviera-Chablais) have been selected. All patients undergoing elective radical and simple cystectomy will be randomly assigned to receive 7 days of preoperative IN (Oral Impact^®, Nestlé, Switzerland) versus standard of care (control group) and followed for 90 days after surgery. For the exploratory outcomes, blood, serum, urine, and stool samples will be collected in patients treated at Lausanne. In order to determine the impact of IN on immune fitness, patients enrolled at Lausanne will be vaccinated against influenza and the establishment of the vaccine-specific immune response will be followed. Analysis of the microbiota and expression of argininosuccinate synthetase 1 as potential biomarker will also be performed.

DISCUSSION AND CONCLUSION: Strengths of the INCyst study include the randomized, multicenter, prospective design, the large number of patients studied, and the translational investigation. This study will challenge the added value of preoperative IN in patients undergoing cystectomy, assessing the clinical effect of IN on the onset of postoperative morbidity and mortality after cystectomy. Furthermore, it will provide invaluable data on the host immune response and microbiota composition.

Prognostic value of the geriatric nutritional risk index in patients with non-metastatic clear cell renal cell carcinoma: a propensity score matching analysis

Sat, 28 Sep 2024 00:00:00 +0000

Nutr J. 2024 Sep 28;23(1):114. doi: 10.1186/s12937-024-01010-7.

ABSTRACT

BACKGROUND: This study aimed to investigate the prognostic value of the geriatric nutritional risk index (GNRI) in patients with non-metastatic clear cell renal cell carcinoma (ccRCC) who underwent nephrectomy.

METHODS: Patients with non-metastatic ccRCC who underwent nephrectomy between 2013 and 2021 were analyzed retrospectively. The GNRI was calculated within one week before surgery. The optimal cut-off value of GNRI was determined using X-tile software, and the patients were divided into a low GNRI group and a high GNRI group. The Kaplan-Meier method was used to compare the overall survival (OS), cancer-specific survival (CSS) and recurrence-free survival (RFS) between the two groups. Univariate and multivariate Cox proportional hazard models were used to determine prognostic factors. In addition, propensity score matching (PSM) was performed with a matching ratio of 1:3 to minimize the influence of confounding factors. Variables entered into the PSM model were as follows: sex, age, history of hypertension, history of diabetes, smoking history, BMI, tumor sidedness, pT stage, Fuhrman grade, surgical method, surgical approach, and tumor size.

RESULTS: A total of 645 patients were included in the final analysis, with a median follow-up period of 37 months (range: 1-112 months). The optimal cut-off value of GNRI was 98, based on which patients were divided into two groups: a low GNRI group (≤ 98) and a high GNRI group (> 98). Kaplan-Meier analysis showed that OS (P < 0.001), CSS (P < 0.001) and RFS (P < 0.001) in the low GNRI group were significantly worse than those in the high GNRI group. Univariate and multivariate Cox analysis showed that GNRI was an independent prognostic factor of OS, CSS and RFS. Even after PSM, OS (P < 0.05), CSS (P < 0.05) and RFS (P < 0.05) in the low GNRI group were still worse than those in the high GNRI group. In addition, we observed that a low GNRI was associated with poor clinical outcomes in elderly subgroup (> 65) and young subgroup (≤ 65), as well as in patients with early (pT1-T2) and low-grade (Fuhrman I-II) ccRCC.

CONCLUSION: As a simple and practical tool for nutrition screening, the preoperative GNRI can be used as an independent prognostic indicator for postoperative patients with non-metastatic ccRCC. However, larger prospective studies are necessary to validate these findings.

Preoperative blood-based nutritional biomarkers as significant prognostic factors after intravesical BCG therapy in patients with non-muscle-invasive bladder cancer

Mon, 22 Jul 2024 00:00:00 +0000

World J Urol. 2024 Jul 22;42(1):428. doi: 10.1007/s00345-024-05148-1.

ABSTRACT

The aim of this study was to investigate the prognostic role of blood-based nutritional biomarkers, including red blood cell (RBC count), hemoglobin (Hb), total protein (TP), albumin, the serum albumin to globulin ratio (AGR) and the prognostic nutritional index (PNI) in patients who underwent intravesical treatment for non-muscle invasive bladder cancer (NMIBC). A total of 501 NMIBC patients who received intravesical Bacillus Calmette-Guerin (BCG) treatment following transurethral resection of bladder tumor (TURBT) were included. The optimal cutoff values for these nutrition-based indicators were determined using receiver operating characteristic curve analysis. We observed a significantly higher recurrence-free survival (RFS) rate in patients with elevated levels of RBC count, Hb, TP, and albumin. Cox univariate and multivariate Cox regression analyses demonstrated that serum albumin (P = 0.002, HR = 0.51, 95%CI: 0.33-0.78), RBC count (P = 0.002, HR = 0.50, 95%CI: 0.32-0.77), TP (P = 0.028, HR = 0.62, 95%CI: 0.41-0.95), Hb (P = 0.004, HR = 0.53, 95%CI: 0.33-0.84), AGR (P = 0.003, HR = 0.46, 95%CI: 0.27-0.76) and PNI (P = 0.019, HR = 0.56, 95%CI: 0.35-0.91) were significant independent factors predicting RFS. These cost-effective and convenient blood-based nutritional biomarkers have the potential to serve as valuable prognostic indicators for predicting recurrence in NMIBC patients undergoing BCG-immunotherapy.

Analysis of preoperative nutrition, immunity and inflammation correlation index on the prognosis of upper tract urothelial carcinoma surgical patients: a retrospective single center study

Mon, 15 Jul 2024 00:00:00 +0000

BMC Surg. 2024 Jul 16;24(1):208. doi: 10.1186/s12893-024-02496-y.

ABSTRACT

BACKGROUND: SII, PNI, SIRI, AAPR, and LIPI are prognostic scores based on inflammation, nutrition, and immunity. The purpose of this study was to examine the prognostic value of the SII, PNI, SIRI, AAPR, and LIPI in patients with UTUC who underwent radical nephroureterectomy with bladder cuff excision.

MATERIALS AND METHODS: Data of UTUC patients in Sichuan Provincial People's Hospital from January 2017 to December 2021 were collected. The optimal critical values of SII, PNI, SIRI, and AAPR were determined by ROC curve, and LIPI was stratified according to the dNLR and LDH. The Kaplan-Meier method was used to draw the survival curve, and Cox proportional hazard model was used to analyze the factors affecting the prognosis of UTUC patients.

RESULTS: A total of 81 patients with UTUC were included in this study. The optimal truncation value of PNI, SII, SIRI and AAPR were determined to be 48.15, 596.4, 1.45 and 0.50, respectively. Univariate Cox proportional hazard regression showed that low PNI, high SII, high SIRI, low AAPR and poor LIPI group were effective predictors of postoperative prognosis of UTUC patients. Multivariate Cox proportional hazard regression showed that high SII was an independent risk factor for postoperative prognosis of UTUC patients. According to ROC curve, the prediction efficiency of fitting indexes of PNI, SII, SIRI, AAPR and LIPI is better than that of using them alone.

CONCLUSIONS: The SII, PNI, SIRI, AAPR, and LIPI was a potential prognostic predictor in UTUC patients who underwent radical nephroureterectomy with bladder cuff excision.

The Controlling Nutritional Status (CONUT) Score as a Predictor of Local Recurrence in Patients Underwent Partial Nephrectomy Alongside the R.E.N.A.L. Nephrometry Score

Tue, 09 Jul 2024 00:00:00 +0000

Urol J. 2024 Oct 12;21(5):313-319. doi: 10.22037/uj.v21i.8045.

ABSTRACT

PURPOSE: This study aims to assess the utility of the CONUT (Controlling Nutritional Status) Score and R.E.N.A.L. (Renal Nephrometry Score) Score in predicting tumor recurrence in patients with kidney cancer. Additionally, we investigated which parameters contributed to these scores.

MATERIALS AND METHODS: In total, 115 patients who underwent partial nephrectomy between January 2015 and August 2023 at a single tertiary center were enrolled. After the exclusion criteria, data from 88 patients were analyzed. Age, gender, body mass index (BMI), comorbidities (hypertension, diabetes), smoking status, tumor characteristics, CONUT Scores, and R.E.N.A.L. scores were retrospectively recorded. Statistical analyses were performed, and significant p was p < 0.05.

RESULTS: The presence of diabetes and hypertension showed a statistically significant association with tumor recurrence (p = 0.033 and p = 0.003, respectively). A high BMI significantly increased the risk of recurrence (p < 0.05). There was a strong positive relationship between the high tumor stage and positive surgical margins with recurrence (p < 0.001). Patients with high R.E.N.A.L. Scores and high CONUT Scores had a higher risk of recurrence (42.1% and 8.7%, respectively), and this difference was statistically significant (p < 0.001).

CONCLUSION: CONUT and R.E.N.A.L. scores may be used to predict tumor recurrence after partial nephrectomy. Additionally, diabetes, hypertension, high BMI, and positive surgical margin rate might affect surgical success rate for recurrences. Clinicians should consider all these parameters and coring systems to gather more successful results after partial nephrectomy.

Factors influencing health-related quality of life in patients with bladder or kidney cancer: a prospective cohort study of the impact of nutritional status and frailty phenotype

Tue, 02 Jul 2024 00:00:00 +0000

J Cancer Surviv. 2025 Jun;19(3):743-753. doi: 10.1007/s11764-024-01637-9. Epub 2024 Jul 2.

ABSTRACT

PURPOSE: This study aimed to investigate the impact of nutritional status and frailty phenotype and the predictors of temporal changes on health-related quality of life (HRQoL) of patients with bladder or kidney cancer.

METHODS: Frailty phenotype, Patient-Generated Subjective Global Assessment, and Quality-of-life questionnaire Core-30 were applied twice to patients diagnosed with bladder or kidney cancer. Patients also completed a sociodemographic questionnaire, and clinical data were collected from records.

RESULTS: Sixty-two individuals completed the study, mostly male, with a mean age of 62.5 (± 11.4) years. The median time of follow-up was 14.5 months. Role functioning, emotional functioning, and fatigue improved over time (p < 0.05). The factors that negatively affected the long-term quality of life summary score were being female, malnourished, pre-frail and frail, cancer treatment, performance status, and lower income. Using the multivariate model, being malnourished (β = - 7.25; 95% CI, - 10.78 to - 3.71; p < 0.001), frail (β = - 7.25; 95% CI, - 13.39 to - 1.11; p = 0.021), and each one-point increase in performance status (β = - 6.9; 95% CI, - 9.54 to - 4.26; p < 0.001), were the ones that most negatively impacted the HRQoL between the two assessments.

CONCLUSION: This study confirmed that frailty, nutritional status, and performance status are the main predictors of HRQoL of patients with bladder or kidney cancer over time.

IMPLICATIONS FOR CANCER SURVIVORS: These findings may be the first step towards highlighting the importance of preventing malnutrition and frailty, in favor of a better long-term QoL for cancer patients.

Effects of a Personalized Diet on Nutritional Status and Renal Function Outcome in Nephrectomized Patients with Renal Cancer

Sat, 11 May 2024 00:00:00 +0000

Nutrients. 2024 May 3;16(9):1386. doi: 10.3390/nu16091386.

ABSTRACT

Nutritional therapy (NT) based on a controlled protein intake represents a cornerstone in managing chronic kidney disease (CKD). However, if a CKD patient is at the same time affected by cancer, oncologists and nutritionists tend to suggest a dietary regimen based on high protein intake to avoid catabolism and malnutrition. International guidelines are not clear when we consider onco-nephrological patients and, as a consequence, no clinical shared strategy is currently applied in clinical practice. In particular, no precise nutritional management is established in nephrectomized patients for renal cell carcinoma (RCC), a specific oncological cohort of patients whose sudden kidney removal forces the remnant one to start a compensatory mechanism of adaptive hyperfiltration. Our study aimed to investigate the efficacy of a low-normal-protein high-calorie (LNPHC) diet based on a Mediterranean model in a consecutive cohort of nephrectomized RCC patients using an integrated nephrologist and nutritionist approach. A consecutive cohort of 40 nephrectomized RCC adult (age > 18) patients who were screened for malnutrition (malnutrition screening tool, MST < 2) were enrolled in a tertiary institution between 2020 and 2022 after signing a specific informed consent form. Each patient underwent an initial nephrological and nutritional evaluation and was subsequently subjected to a conventional CKD LNPHC diet integrated with aproteic foods (0.8 g/Kg/die: calories: 30-35 kcal per kg body weight/die) for a period of 6 months (±2 months). The diet was structured after considering eGFR (CKD-EPI 2021 creatinine formula), comorbidities, and nutritional status. MST, body mass index (BMI), phase angle (PA), fat mass percentage (FM%), fat-free mass index (FFMI), body cell mass index (BCMI), extracellular/intracellular water ratio (ECW/ICW), extracellular matrix/body cell mass ratio (ECM/BCM), waist/hip circumference ratio (WHC), lab test exams, and clinical variables were examined at baseline and after the study period. Our results clearly highlighted that the LNPHC diet was able to significantly improve several nutritional parameters, avoiding malnutrition and catabolism. In particular, the LNPHC diet preserved the BCM index (delta on median, ΔM + 0.3 kg/m²) and reduced the ECM/BCM ratio (ΔM - 0.03 *), with a significant reduction in the ECW/ICW ratio (ΔM - 0.02 *), all while increasing TBW (ΔM + 2.3% *). The LNPHC diet was able to preserve FFM while simultaneously depleting FM and, moreover, it led to a significant reduction in urea (ΔM - 11 mg/dL **). In conclusion, the LNPHC diet represents a new important therapeutic strategy that should be considered when treating onco-nephrological patients with solitary kidney due to renal cancer.

Arch Esp Urol. 2024 Mar;77(2):164-172. doi: 10.56434/j.arch.esp.urol.20247702.22.

ABSTRACT

OBJECTIVE: To explore the efficacy of combining the prognostic nutritional index (PNI) and the lymphocyte:monocyte ratio (LMR) for patients with muscle-invasive bladder cancer (MIBC).

METHODS: Of 172 patients who were diagnosed with MIBC in our hospital, 94 were eligible for the study. The clinical data of the 94 patients with MIBC were collected. The patients were divided according to the optimal cut-off values for the preoperative PNI and LMR into a low-PNI subgroup (PNI <44.15, 52 patients), a high-PNI subgroup (PNI ≥44.15, 42 patients), a low-LMR subgroup (LMR <2.98, 50 patients) and a high-LMR subgroup (LMR ≥2.98, 44 patients). The area under the receiver operating characteristic (ROC) curve (AUC) was used to analyse the efficacy of the PNI and the LMR in predicting the prognosis of patients with MIBC. Univariate and multivariate logistic regression analyses were performed to evaluate prognostic factors for patients with MIBC. Kaplan-Meier (K‒M) survival analysis was used for overall survival (OS) analysis to explore the ability of the PNI combined with the LMR to predict the prognosis of patients with MIBC.

RESULTS: The optimal cut-off values for the preoperative PNI and the preoperative LMR were 44.15 and 2.98, respectively, on the basis of ROC curves. ROC curve analysis revealed that the PNI (AUC = 0.720, sensitivity 65.9%, specificity 74.50%, Youden index 0.399) and the LMR (AUC = 0.724, sensitivity 65.9%, specificity 70.0%, Youden index 0.395) both had good prognostic efficacy for patients with MIBC. The results of univariate and multivariate logistic regression analyses showed that preoperative PNI <44.15 was an independent risk factor for OS in patients with MIBC (p = 0.027). Based on K‒M survival curve analysis, patients with PNI <44.15 and LMR <2.98 had the shortest OS (p = 0.00002).

CONCLUSIONS: Low preoperative PNI and LMR values are indicative of poor prognosis in patients with MIBC. The efficacy of their combination was better than that of the factors independently.

Nutritional status as a predictive factor for paediatric tuberous sclerosis complex-associated kidney angiomyolipomas: a retrospective analysis

Thu, 14 Mar 2024 00:00:00 +0000

Eur J Pediatr. 2024 Jun;183(6):2563-2570. doi: 10.1007/s00431-024-05520-8. Epub 2024 Mar 14.

ABSTRACT

The purpose of this study is to determine the predictive factors of tuberous sclerosis complex (TSC)-associated kidney disease and its progression in children. Retrospective review of children with TSC in a tertiary children's hospital was performed. Relevant data were extracted, and Cox proportional hazards regression was used to establish predictors of kidney lesions. Logistic regression was conducted to identify factors predicting chronic kidney disease (CKD) and high-risk angiomyolipomas (above 3 cm). Kidney imaging data were available in 145 children with TSC; of these, 79% (114/145) had abnormal findings. The only significant predictive factor for cyst development was being female (HR = 0.503, 95% CI 0.264-0.956). Being female (HR = 0.505, 95% CI 0.272-0.937) and underweight (HR = 0.092, 95% CI 0.011-0.800) both lowers the risk of having angiomyolipomas, but TSC2 mutations (HR = 2.568, 95% CI 1.101-5.989) and being obese (HR = 2.555, 95%CI 1.243-5.255) increases risks. Ten (12%) of 81 children with kidney function tested demonstrate CKD stages II-V, and only angiomyolipomas above 3 cm predict CKD. Additionally, 13/145 (9%) children had high-risk angiomyolipomas, whereby current age (adjusted odds ratio (aOR) 1.015, 95% CI 1.004-1.026) and being overweight/obese (aOR 7.129, 95% CI 1.940-26.202) were significantly associated with angiomyolipomas above 3 cm.

CONCLUSIONS: While gender and genotype are known predictors, this study includes the novel finding of nutritional status as a predictor of TSC-associated kidney disease. This study sheds light on a possible complex interplay of hormonal influences, obesity, and kidney angiomyolipomas growth, and further investigations focusing on the impact of nutritional status on TSC-associated kidney disease are warranted.

WHAT IS KNOWN: • Gender and genotype are well-studied predictive factors in TSC kidney disease.

WHAT IS NEW: • Nutritional status may influence the development and the progression of kidney lesions in children with TSC and should not be overlooked. • Management guidelines of TSC-associated kidney disease can address nutritional aspects.

Geriatric nutritional risk index as a prognostic factor in elderly patients with non-muscle-invasive bladder cancer: a propensity score-matched study

Thu, 04 Jan 2024 00:00:00 +0000

Int Urol Nephrol. 2024 May;56(5):1627-1637. doi: 10.1007/s11255-023-03905-6. Epub 2024 Jan 4.

ABSTRACT

PURPOSE: The Geriatric Nutrition Risk Index (GNRI) is a simple and validated tool used to assess the nutritional status of elderly patients and predict the risk of short-term postoperative complications, as well as the long-term prognosis, after cancer surgery. In this study, we aimed to evaluate the predictive value of GNRI for the long-term postoperative prognosis in elderly patients with primary non-muscle-invasive bladder cancer (NMIBC) who underwent transurethral resection of bladder tumor (TURBT).

METHODS: We retrospectively analyzed data from 292 elderly patients with primary NMIBC. Using X-tile software, we divided the cohort into two groups based on GNRI and determined the cut-off value for postoperative recurrence-free survival (RFS). Propensity score matching (PSM) with a ratio of 1:3, Kaplan-Meier analysis, log-rank test, and COX proportional hazards regression were used to assess the correlation between GNRI and prognosis and identify factors predicting recurrence and progression.

RESULTS: In the entire cohort, the 3 year recurrence group had significantly lower GNRI compared to the 3 year non-recurrence group (P = 0.0109). The determined GNRI cut-off value was 93.82. After PSM, the low GNRI group had significantly lower RFS (P < 0.0001) and progression-free survival (PFS) (P = 0.0040) than the high GNRI group. Multivariate COX regression showed that GNRI independently predicted RFS (HR 2.108; 95% CI 1.266-3.512; P = 0.004) and PFS (HR 2.155; 95% CI 1.135-4.091; P = 0.019) in elderly patients with primary NMIBC.

CONCLUSION: Preoperative GNRI is a prognostic marker for disease recurrence and progression in elderly patients with primary NMIBC undergoing TURBT.

Nutritional status associated with clinical outcomes in children with solid tumors: A retrospective cohort study from China

Tue, 19 Dec 2023 00:00:00 +0000

Cancer Med. 2024 Jan;13(1):e6798. doi: 10.1002/cam4.6798. Epub 2023 Dec 18.

ABSTRACT

OBJECTIVE: To investigate the long-term changes in nutritional status in children with solid tumors during treatment and the relationship between nutritional status and clinical outcomes.

METHODS: This study was a retrospective medical records review of data from children who were diagnosed with solid tumors and followed up for more than 3 months from January 2016 to December 2021 in China. Patient demographics and clinical information, including nutritional status, parenteral nutrition use, intensive care unit (ICU) transfers, infection during hospitalization, hospitalization frequency, length of stay, hospitalization costs and antibiotic costs, were collected to analyze the nutritional status of children with different types of solid tumors, the dynamic changes in nutritional status during treatment, and the relationship between nutritional status and clinical outcomes.

RESULTS: Among the 764 patients (383 males (50.1%); 381 females (49.9%); mean age: 2.58 years), 41.6% of the solid tumors were neuroblastomas, 17.1% were hepatoblastomas, and Wilms tumors as the third most common solid tumors (8.9%). The median follow-up duration was 6 months (range: 3-40 months). At diagnosis, the proportion of children who were undernourished (underweight and wasting) versus overweight or obese were 26.71% versus 5.21% (25.86% vs. 2.89% in the third month; 29.77% vs. 2.28% in the sixth month; 24.77% vs. 3.27% in the 12th month). The body mass index Z scores decreased from the initial values after the first month (-0.56 (-1.47, 0.23) vs. -0.44 (-1.29, 0.41)) but improved later and decreased again at 6 months. The children in the undernutrition group had longer hospital stays (p < 0.001), higher hospitalization costs (p < 0.001), higher antibiotic costs (p < 0.001), a higher risk of neutropenia (OR = 4.781 (95% CI: 1.571-14.553), p = 0.006), and a higher risk of ICU transfers (OR = 1.498 (95% CI: 1.010-2.224), p = 0.044). No significant differences in those associations by malnutrition and infection, ICU duration, or length of parenteral nutrition were observed.

CONCLUSION: There is a considerable prevalence of malnutrition in children with solid tumors. Malnutrition is related to adverse clinical outcomes and increases in total hospital expenses and antibiotic costs.

Clinical utility of the prognostic nutritional index in patients with metastatic hormone-sensitive prostate cancer: A retrospective, multicenter, cohort study

Sun, 10 Sep 2023 00:00:00 +0000

Prostate. 2023 Dec;83(16):1610-1618. doi: 10.1002/pros.24619. Epub 2023 Sep 10.

ABSTRACT

BACKGROUND: The prognostic nutritional index (PNI) based on the serum albumin level and the lymphocyte count has been investigated as a prognostic factor in patients with malignant tumors. However, it has been poorly studied in prostate cancer (PCa), and little is known about its clinical utility.

METHODS: Clinical data of 353 patients with de novo, metastatic, hormone-sensitive PCa (mHSPC) who received androgen deprivation therapy (ADT) were obtained from multiple institutions between 2000 and 2019. The impacts of the pretreatment PNI level on treatment response and survival, together with clinical parameters, were examined. The Mann-Whitney U test, Cox proportional hazards models, and Kaplan-Meier methods were used to evaluate significance.

RESULTS: The median age and initial prostate-specific antigen level were 73 and 266.18 ng/mL, respectively. Patients with a low PNI had shorter progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS) (p < 0.0001). On multivariate analysis, low PNI was an independent prognostic factor for OS (p = 0.0027, HR = 1.65), as well as advanced age (p = 0.049, HR = 1.38), the International Society of Urological Pathology (ISUP) grade group (GG) 5 (p = 0.0027, HR = 1.69), and elevated lactate dehydrogenase (LDH) (p < 0.0001, HR = 2.08). A propensity score-matching analysis showed that the PNI level remained a significant prognostic biomarker for PFS (p = 0.0263), CSS (p = 0.0006), and OS (p = 0.0015). Furthermore, a novel risk classification using PNI, LDH, and the ISUP GG was established to stratify patients' prognosis. An increase in the number of risk factors was significantly correlated with poor outcomes.

CONCLUSIONS: A low pretreatment PNI might be an effective biomarker of poor treatment response and survival in patients with mHSPC undergoing ADT.

Relationship between Bladder Cancer, Nutritional Supply, and Treatment Strategies: A Comprehensive Review

Sat, 09 Sep 2023 00:00:00 +0000

Nutrients. 2023 Aug 31;15(17):3812. doi: 10.3390/nu15173812.

ABSTRACT

Bladder cancer (BC) is the predominant neoplasm affecting the urinary system and ranks among the most widespread malignancies globally. The causes of bladder cancer include genetic factors; age; sex; and lifestyle factors, such as imbalanced nutrition, obesity, and metabolic disorders. The lack of proper nutrient intake leads to the development of bladder cancer because insufficient nutrients are consumed to prevent this disease. The purpose of this review was to analyze the nutrients closely linked to the onset and advancement of bladder cancer and to explore the relationship between dietary nutrients and bladder cancer. Particular emphasis was placed on nutrients that are frequently ingested in daily life, including sugar, fat, protein, and others. The focus of this research was to analyze how nutritional intake before and after surgery affects the recovery process of patients who have been diagnosed with bladder cancer. This article seeks to increase awareness among both society and the medical community about the significance of implementing appropriate dietary nutrition to reduce the chances of developing bladder cancer, enhance perioperative care for patients with bladder cancer, and aid in their recuperation.

Prognostic Ability of Nutritional Indices for Outcomes of Bladder Cancer: A Systematic Review and Meta-Analysis

Tue, 29 Aug 2023 00:00:00 +0000

Urol Int. 2023;107(9):886-894. doi: 10.1159/000531884. Epub 2023 Aug 29.

ABSTRACT

BACKGROUND: Nutrition has become an important parameter influencing the prognosis of several cancers. However, its impact on outcomes for bladder cancer (BC) is still unclear. This review examines the association between three commonly used nutritional indices, namely, the prognostic nutritional index (PNI), controlling nutritional status (CONUT), and the geriatric nutritional risk index (GNRI) and outcomes of BC.

METHODS: PubMed, CENTRAL, Scopus, Web of Science, Embase, and Google Scholar were explored for studies published up to April 13, 2023. Data from studies were pooled to examine the association between PNI, CONUT, or GNRI and overall survival (OS) and recurrence-free survival (RFS).

RESULTS: Thirteen studies were included. Meta-analysis demonstrated significantly poor OS with low PNI versus high PNI in BC patients (hazard ratio [HR]: 1.71; 95% confidence interval [CI]: 1.37, 2.14; I2 = 0%). This result remained significant in various subgroup analyses. However, no association was noted between PNI and RFS (HR: 1.22; 95% CI: 0.67, 2.24; I2 = 84%). Meta-analysis showed that patients with high CONUT scores had significantly poor OS (HR: 2.43; 95% CI: 1.82, 3.25; I2 = 0%) as well as RFS (HR: 2.90; 95% CI: 2.10, 4.01; I2 = 0%). Data on GNRI were scarce and conflicting.

CONCLUSION: Limited data show that PNI and CONUT are predictive of outcomes in BC. Low PNI was associated with poor OS, while high CONUT was associated with poor OS and RFS. Data on GNRI are too scarce to obtain conclusions. Further studies are needed to supplement the results.

Risk Investigation and Analysis of Risk Factors for Malnutrition in Patients with Advanced Kidney Cancer: A Single-Centre Retrospective Study

Mon, 07 Aug 2023 00:00:00 +0000

Arch Esp Urol. 2023 Jul;76(5):328-334. doi: 10.56434/j.arch.esp.urol.20237605.38.

ABSTRACT

OBJECTIVE: To investigate the nutritional status of patients with advanced kidney cancer and analyse the risk factors for malnutrition in such patients.

METHODS: The study selected the clinical data of 103 patients with advanced kidney cancer who were admitted to Qingdao Jiaozhou Central Hospital from February 2020 to February 2022 for a retrospective analysis. The Subjective Global Assessment of Nutrition scale was used to evaluate the nutritional status of all research subjects. Patients' baseline data, such as gender, age and clinical classifications, and laboratory indicators, such as albumin and C-reactive protein (CRP), were collected, and multivariate logistic regression was used to screen the independent risk factors for malnutrition in patients with advanced kidney cancer.

RESULTS: A total of 78 (76.00%) individuals among the 103 patients with advanced kidney cancer had malnutrition. The results of univariate analysis showed marked differences in the age, body mass index (BMI), albumin, haemoglobin, CRP, diabetes, anorexia and family monthly income of patients of the good nutrition and malnutrition groups (p < 0.05). The results of logistic regression showed that age ≥65 years old (odds ratio (OR) = 29.187), albumin <40 g/L (OR = 0.025), haemoglobin <110 g/L (OR = 0.049), the presence of diabetes (OR = 28.138), the presence of anorexia (OR = 98.739), BMI <18.5 kg/m² (OR = 0.024) and CRP <3 mg/L (OR = 24.819) were independent influencing factors of malnutrition in the patients with advanced kidney cancer (all p < 0.05).

CONCLUSIONS: The incidence of malnutrition in patients with advanced kidney cancer is relatively high. Therefore, the understanding of malnutrition in such patients in clinical work must be fortified, and attention should be paid to screening the above risk factors and implementing active measures in nutrition therapy to reduce the risk of malnutrition in patients with advanced kidney cancer and prolong their survival time.

Prognostic nutritional index combined with NLR to construct a survival prediction model and decision analysis of patients with muscle-invasive bladder cancer after surgery

Thu, 18 May 2023 00:00:00 +0000

Cancer Med. 2023 Jul;12(13):14207-14224. doi: 10.1002/cam4.6088. Epub 2023 May 18.

ABSTRACT

OBJECTIVES: To build a nomogram prediction model, assess its predictive ability, and perform a survival decision analysis on patients with muscle-invasive bladder cancer (MIBC) to study risk factors affecting overall survival (OS).

METHODS: A retrospective analysis was performed on the clinical information of 262 patients with MIBC who underwent radical cystectomy (RC) at the Urology Department of the Second Affiliated Hospital of Kunming Medical University between July 2015 and August 2021. The final model variables that were included were chosen using single-factor stepwise Cox regression, optimal subset regression, and LASSO regression + cross-validation with the minimum AIC value. The next step was to do a multivariate Cox regression analysis. The establishment of a nomogram model by fitting and the screening out of independent risk factors impacting the survival of patients with MIBC having radical resection. Receiver Activity Characteristic curves, C-index, and a calibration plot evaluated the prediction accuracy, validity, and clinical benefit of the model. The 1-, 3-, and 5-year survival rates were then computed for each risk factor using a Kaplan-Meier survival analysis.

RESULTS: 262 eligible patients in total were enrolled. With a median follow-up of 32 months, the follow-up period ranged from 2 to 83 months. 171 cases (65.27%) survived while 91 cases (34.73%) perished. Age (HR = 1.06 [1.04; 1.08], p = 0.001), preoperative hydronephrosis (HR = 0.69 [0.46, 1.05], p = 0.087), T stage (HR = 2.06 [1.09, 3.93], p = 0.027), lymphovascular invasion (LVI, HR = 1.73 [1.12, 2.67], p = 0.013), prognostic nutritional index (PNI, HR = 1.70 [1.09, 2.63], p = 0.018), and neutrophil-to-lymphocyte ratio (NLR, HR = 0.52 [0.29, 0.93)], p = 0.026) were independent risk factor for the survival of bladder cancer patients. Create a nomogram based on the aforementioned findings, and then draw the 1-year, 3-year, and 5-year OS receiver operating characteristic curves by the nomogram. The AUC values were 0.811 (95% CI [0.752, 0.869]), 0.814 (95% CI [0.755, 0.873]), and 0.787 (95% CI [0.708, 0.865]), respectively, and the calibration plot matched the predicted value well. The 1-year, 3-year, and 5-year decision curve analyses were higher than the ALL line and None line at threshold values of >5%, 5%-70%, and 20%-70% indicating that the model has good clinical applicability. The calibration plot for the Bootstrap 1000-time resampled validation model was similar to the actual value. Patients with preoperative combination hydronephrosis, higher T-stage, combined LVI, low PNI, and high NLR had worse survival, according to Kaplan-Meier survival analysis for each variable.

CONCLUSIONS: This study might conclude that PNI and NLR were separate risk factors that affect a patient's OS after RC for MIBC. The prognosis of bladder cancer may be predicted by PNI and NLR, but additional confirmation in randomized controlled trials is required.

Clinical significance of prognostic nutritional index (PNI)-monocyte-to-lymphocyte ratio (MLR)-platelet (PLT) score on postoperative outcomes in non-metastatic clear cell renal cell carcinoma

Wed, 10 May 2023 00:00:00 +0000

BMC Surg. 2023 May 10;23(1):117. doi: 10.1186/s12893-023-02001-x.

ABSTRACT

BACKGROUND: Prognositic nutritional index (PNI), monocyte-to-lymphocyte ratio (MLR) and platelet (PLT) are associated with tumor survival in many human malignancies. Whereas, no study combined PNI-MLR-PLT score and indicated its predictive significance on the prognosis of patients with non-metastatic clear cell renal cell carcinoma (ccRCC).

METHODS: In this study, we retrospectively collected the clinicopathological characteristics and prognostic data from 164 cases of non-metastatic ccRCC and aimed to determine the clinical significance of PNI-MLR-PLT score on patients' outcomes after surgery. The optimal cut-off values of PNI (PNI > 47.40 vs PNI < 47.40), MLR (MLR > 0.31 vs MLR < 0.31) and PLT (PLT > 245 vs PLT < 245) were identified with relative operating characteristic (ROC) curve analysis. The PNI-MLR-PLT score system was established by the value of three indexes, each indication was assigned a score of 0 or 1. Overall survival (OS) and metastasis-free survival (MFS) were analyzed using Kaplan-Meier estimate and Cox regression models.

RESULTS: The mean follow-up period was 85.67 months. Eight (5.0%) patients died, 4 (2.0%) relapsed, and 7 (4.0%) developed metastasis after surgery. The 3-year OS and MFS rates were 98.2% and 97.6%, and the 5-year OS and MFS rates were both 90.2%. Our results suggested that PNI-MLR-PLT score negatively correlated with pathological T stage and tumor grade. Survival outcomes revealed that lower PNI-MLR-PLT score is associated with inferior OS (P < 0.001) and MFS (P < 0.001) after surgery. Subgroup analysis regarding pathological T stage, tumor grade and surgical modalities obtained consistent results. univariable and multivariable Cox analysis showed that high PNI-MLR-PLT score was the independent protective factor of tumor survival in non-metastatic ccRCC patients.

CONCLUSIONS: Our data suggested that PNI-MLR-PLT score could serve as a promising independent prognostic factor in patients with non-metastatic ccRCC.

The impact of nutritional status and changes of body composition on the prognosis of metastatic renal cell carcinoma patients

Wed, 10 May 2023 00:00:00 +0000

J Med Invest. 2023;70(1.2):80-87. doi: 10.2152/jmi.70.80.

ABSTRACT

PURPOSE: This study aimed to analyze the impact of patients' nutritional status and changes in body composition on the prognosis of metastatic renal cell carcinoma (mRCC) patients who received systemic therapy with tyrosine kinase inhibitors (TKIs).

METHODS: A total of 57 mRCC patients who received systemic therapy with TKIs as first-line therapy at our facility between November 2004 and October 2018 were included. The Prognostic Nutritional Index (PNI) was used to evaluate their nutritional status. The volumes of skeletal muscle mass and fat tissue were calculated using the SYNAPSE VINCENT system. The effects of nutritional status and body composition of mRCC patients on progression-free survival (PFS) and overall survival (OS) were analyzed using Cox regression methods.

RESULTS: Low PNI at the start of systemic therapy was a significant prognostic predictor for OS (HR 3.807 [95% CI 1.205-12.027], P=0.046), and it was related to loss of muscle mass three months after systemic therapy. Although the loss of muscle mass at the start of systemic therapy was not associated with OS, loss of muscle mass during treatment predicted worse OS.

CONCLUSIONS: Nutritional status of mRCC patients may predict changes in body composition and be associated with their prognosis. J. Med. Invest. 70 : 80-87, February, 2023.

Investigating the differences in nutritional status between successfully weaned and unsuccessfully weaned respirator patients

Tue, 02 May 2023 00:00:00 +0000

Sci Rep. 2023 May 2;13(1):7144. doi: 10.1038/s41598-023-34432-0.

ABSTRACT

Long-term respirator users admitted to intensive care units need to be transferred to a respiratory care center (RCC) for weaning. It may cause malnutrition in critical care patients, which may manifest as a reduction in respiratory muscle mass, lower ventilatory capacity, and decreased respiratory tolerance. This study aimed to assess that if the patients' nutritional status were improved, it could help RCC patients to wean from respirators. All participants were recruited from the RCC of a medical foundation in the city and Taipei Tzu Chi Hospital. The indicators include serum albumin level, respirator detachment index, maximum inspiratory pressure (PImax), rapid shallow breathing index, and body composition measurements. We recorded the length of hospital stay, mortality, and RCW (respiratory care ward) referral rate for these participants and analyzed the differences in relevant research indicators between those who were and weren't weaned off. 43 of 62 patients were weaned from respirators, while 19 failed. The resuscitation rate was 54.8%. Patients with respirator weaning had a lower number of RCC admission days (23.1 ± 11.1 days) than respirator-dependent patients (35.6 ± 7.8 days, P < 0.05). The PImax of successfully weaned patients had a greater reduction (- 27.09 ± 9.7 cmH₂O) than unsuccessful ones (- 21.4 ± 10.2 cmH₂O, P < 0.05). The Acute Physiology and Chronic Health Evaluation II (APACHE II) scores of successfully weaned patients (15.8 ± 5.0) were lower than those who were not (20.4 ± 8.4, P < 0.05). There was no significant difference in serum albumin levels between the two groups. In the successfully weaned patients, the serum albumin concentration was increased from 2.2 ± 0.3 to 2.5 ± 0.4 mg/dL, P < 0.05. Improved nutritional status can help RCC patients to wean from respirators.

Hemoglobin, Albumin, Lymphocyte, and Platelet Count is a Significant Biomarker Surrogate for Nutritional Status to Predict Overall Survival in Patients Post-radical Cystectomy

Thu, 27 Apr 2023 00:00:00 +0000

Urol Pract. 2023 May;10(3):262-269. doi: 10.1097/UPJ.0000000000000386. Epub 2023 Jan 24.

ABSTRACT

INTRODUCTION: Nutritional status is an independent predictor of overall survival after radical cystectomy. Various biomarkers of nutritional status are proposed to predict postoperative outcome, including albumin, anemia, thrombocytopenia, and sarcopenia. Recently, a score comprising hemoglobin, albumin, lymphocyte, and platelet counts was postulated as an encompassing biomarker to predict overall survival post-radical cystectomy in a single-institution study. However, cutoffs for hemoglobin, albumin, lymphocyte, and platelet count are not well defined. In this study, we analyzed hemoglobin, albumin, lymphocyte, and platelet count thresholds predicting overall survival and examined the platelet-to-lymphocyte as an additional prognostic biomarker.

METHODS: Fifty radical cystectomy patients were retrospectively evaluated from 2010-2021. American Society of Anesthesiologists classification, pathological data, and survival were extracted from our institutional registry. Univariable and multivariable Cox regression analysis was fit to the data to predict overall survival.

RESULTS: Median follow-up was 22 (12-54) months. Hemoglobin, albumin, lymphocyte, and platelet count (continuous) was a significant predictor of overall survival on multivariable Cox regression analysis (HR 0.95, 95% CI: 0.90-0.99, P = .03), adjusting for Charlson Comorbidity Index, lymphadenopathy (pN >N0), muscle-invasive disease, and neoadjuvant chemotherapy. Optimal hemoglobin, albumin, lymphocyte, and platelet count cutoff was 25.0. Patients with hemoglobin, albumin, lymphocyte, and platelet count <25.0 had inferior overall survival (median, 33 months) vs with those with hemoglobin, albumin, lymphocyte, and platelet count ≥25.0 (median, not reached) (P = .03).

CONCLUSIONS: Low hemoglobin, albumin, lymphocyte, and platelet count <25.0 was an independent predictor of inferior overall survival.

Development of an immune-nutritional prognostic index in patients with muscle-infiltrating bladder cancer candidates for radical cystectomy

Thu, 20 Apr 2023 00:00:00 +0000

Actas Urol Esp (Engl Ed). 2023 Jan-Feb;47(1):34-40. doi: 10.1016/j.acuroe.2022.09.001. Epub 2022 Sep 6.

ABSTRACT

INTRODUCTION: Muscle-infiltrating bladder tumor (MIBT) has a recurrence-free survival (RFS) of 50% at 5 years. Although neoadjuvant chemotherapy (NCT) has increased it by 8%, which group of patients benefits the most from this treatment remains unclear.

OBJECTIVE: Evaluate the prognostic value of immune-nutritional status in patients with MIBT who are candidates for cystectomy, and to develop a score that allows identifying patients with a worse prognosis (pT3-4 and/or pN0-1).

MATERIAL AND METHODS: A retrospective analysis was carried out on 284 patients with MIBT treated with radical cystectomy. Preoperative laboratory tests were analyzed and immune-nutritional indices were calculated. The Kaplan-Meier method was used to calculate the PFS. Cox regression was used for multivariate analysis.

RESULTS: Univariate analysis showed a statistically significant relationship with leukocyte/lymphocyte index (p = 0.0001), neutrophil/lymphocyte index (p = 0.02), prognostic nutritional index (p = 0.002), and platelet/lymphocyte ratio (p = 0.002). In multivariate analysis, the leukocyte/lymphocyte ratio (p = 0.002) and PNI (p = 0.04) behaved as independent prognostic factors of decreased RFS. Based on these, a prognostic score was developed to classify patients into 3 prognostic groups. Eighty percent of patients with pT3-4 and/or pN0-1 tumors were in the intermediate-poor prognostic groups.

CONCLUSION: The implementation of a precystectomy immune-nutritional score in clinical practice would help in the selection of a group of patients with a more unfavorable pathologic stage and worse PFS. We believe that these patients could benefit more from a NACT.

Controlling nutritional status score in predicting International Society of Urological Pathology score upgrading and biochemical recurrence after radical prostatectomy

Fri, 07 Apr 2023 00:00:00 +0000

Asia Pac J Clin Oncol. 2024 Oct;20(5):582-588. doi: 10.1111/ajco.13951. Epub 2023 Apr 7.

ABSTRACT

AIM: The aim of our study was to assess the predictive value of controlling nutritional status (CONUT) score for the prognosis of prostate cancer.

METHODS: A total of 257 patients' characteristics, prostate-specific antigen (PSA) values, biopsy, and pathological specimen features were all recorded. The CONUT score was calculated for each patient from three blood parameters: total lymphocyte count (TLC), serum albumin, and cholesterol concentrations. Spearman's correlation coefficient was used to assess the correlation between the total CONUT score and the variables including age, body mass index, prostate volume, PSA, biopsy and pathological specimen features, and PSA-recurrence free survival (PSA-RFS) time. The Kaplan-Meier method and log-rank test were used for PSA-RFS analysis. Regression analyses were performed to assess the association between clinicopathological factors, the International Society of Urological Pathology (ISUP) upgrading, and biochemical recurrence (BCR).

RESULTS: Statistically significant differences were determined in pathologic ISUP grade, and total tumor volume between low and high CONUT score groups. Additionally, the high CONUT score group had a significantly higher BCR rate and lower PSA-RFS when compared with the low CONUT score group. A strong positive correlation between total CONUT score and pathologic ISUP grade and a moderate negative correlation between total CONUT score and PSA-RFS was determined. In multivariate analysis, a total CONUT score ≥2 had a statistically significant association with ISUP upgrading (odds ratio [OR] = 3.05) and BCR (3.52).

CONCLUSION: Preoperative CONUT score is an independent predictive factor for ISUP score upgrading and BCR in patients who undergo radical prostatectomy.

Predictive Value of Inflammatory and Nutritional Indexes in the Pathology of Bladder Cancer Patients Treated with Radical Cystectomy

Tue, 28 Mar 2023 00:00:00 +0000

Curr Oncol. 2023 Feb 21;30(3):2582-2597. doi: 10.3390/curroncol30030197.

ABSTRACT

In recent years, the focus of numerous studies has been the predictive value of inflammatory and nutritional parameters in oncology patients. The aim of our study was to examine the relationship between the inflammatory and nutritional parameters and the histopathological characteristics of patients with bladder cancer. A retrospective study included 491 patients who underwent radical cystectomy for bladder cancer between 2017 and 2021. We calculated the preoperative values of the neutrophil-to-lymphocyte ratio (NLR), the derived neutrophil-to-lymphocyte ratio (dNLR), the systemic immune-inflammation index (SII), the systemic inflammatory response index (SIRI), the platelet-to-lymphocyte ratio (PLR), the lymphocyte-to-monocyte ratio (LMR), the prognostic nutritional index (PNI), and the geriatric nutritional risk index (GNRI). Statistically significant positive correlations were observed between NLR, dNLR, SII, SIRI, and PLR and the pathological stage of the tumor. We observed statistically significant inverse correlations for LMR, PNI, and GNRI with the tumor stage. SIRI was identified as an independent predictor of the presence of LVI. dNLR was identified as an independent predictor of positive surgical margins. GNRI was identified as an independent predictor of the presence of metastases in the lymph nodes. We noticed the predictive value of SIRI, dNLR, and GNRI in the pathology of bladder cancer patients.

Immune-inflammatory-nutritional status predicts oncologic outcomes after radical cystectomy for urothelial carcinoma of bladder

Thu, 02 Feb 2023 00:00:00 +0000

Actas Urol Esp (Engl Ed). 2023 Sep;47(7):430-440. doi: 10.1016/j.acuroe.2023.01.001. Epub 2023 Jan 31.

ABSTRACT

OBJECTIVE: To perform the first investigation of the role of immune-inflammatory-nutritional status (INS) on oncological outcomes in patients undergoing open radical cystectomy (ORC) for urothelial carcinoma (UC).

MATERIALS AND METHODS: The records of consecutive patients who underwent ORC for non-metastatic bladder cancer between 2009 and 2020 were retrospectively analyzed. Neoadjuvant chemotherapy, non-urothelial tumor biology, and absence of oncological follow-up were exclusion criteria. Systemic immune-inflammatory index (SII) and Prognostic Nutritional Index (PNI) values were calculated and optimal cut-off values for these were used to designate four subgroups: "high SII-high PNI", "low SII-high PNI", "low SII-low PNI", and "high SII-low PNI". The Low SII-high PNI INS group had best overall survival (OS) rate while the remainder were included in non-favorable INS group. Survival curves were constructed, and a multivariate Cox regression model was used for OS and recurrence-free survival (RFS).

RESULTS: After exclusions, the final cohort size was 173 patients. The mean age was 64.31 ± 8.35 and median follow-up was 21 (IQR: 9-58) months. Optimal cut-off values for SII and PNI were 1216 and 47, respectively. The favorable INS group (low SII-high PNI, n = 89) had the best OS rate (62.9%). Multivariate Cox regression analysis indicated that non-favorable INS (n = 84) was a worse independent prognostic factor for OS (HR: 1.509, 95%CI: 1.104-3.145, p = 0.001) and RFS (HR: 1.285; 95%CI: 1.009-1.636, p = 0.042).

CONCLUSION: Preoperative assessment of INS may be a useful prognostic panel for OS and RFS in patients who had ORC for UC.

Pre-operative prognostic nutritional index as a predictive factor for prognosis in non-metastatic renal cell carcinoma treated with surgery

Tue, 31 Jan 2023 00:00:00 +0000

Beijing Da Xue Xue Bao Yi Xue Ban. 2023 Feb 18;55(1):149-155. doi: 10.19723/j.issn.1671-167X.2023.01.023.

ABSTRACT

OBJECTIVE: To evaluate the implications of the prognostic nutrition index (PNI) in non-metastatic renal cell carcinoma (RCC) patients treated with surgery and to compare it with other hematological biomarkers, including neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and systemic immune inflammation index (SII).

METHODS: A cohort of 328 non-metastatic RCC patients who received surgical treatment between 2010 and 2012 at Peking University First Hospital was analyzed retrospectively. Receiver operating characteristic (ROC) curve analysis was used to determine the optimal cutoff values of the hematological biomarkers. The Youden index was maximum for PNI was value of 47.3. So we divided the patients into two groups (PNI≤ 47. 3 and >47. 3) for further analysis. Categorical variables [age, gender, body mass index (BMI), surgery type, histological subtype, necrosis, pathological T stage and tumor grade] were compared using the Chi-square test and Student' s t test. The association of the biomarkers with overall survival (OS) and disease-free survival (DFS) was analyzed using Kaplan-Meier methods with log-rank test, followed by multivariate Cox proportional hazards model.

RESULTS: According to the maximum Youden index of ROC curve, the best cut-off value of PNI is 47. 3. Low level of PNI was significantly associated with older age, lower BMI and higher tumor pathological T stage (P < 0.05). Kaplan-Meier univariate analysis showed that lower PNI was significantly correlated with poor OS and DFS (P < 0.05). In addition, older age, lower BMI, tumor necrosis, higher tumor pathological T stage and Fuhrman grade were significantly correlated with poor OS (P < 0.05). Cox multivariate analysis showed that among the four hematological indexes, only PNI was an independent factor significantly associated with OS, whether as a continuous variable (HR=0.9, 95%CI=0.828-0.978, P=0.013) or a classified variable (HR=2.397, 95%CI=1.061-5.418, P=0.036).

CONCLUSION: Low PNI was a significant predictor for advanced pathological T stage, decreased OS, or DFS in non-metastatic RCC patients treated with surgery. In addition, PNI was superior to the other hematological biomar-kers as a useful tool for predicting prognosis of RCC in our study. It should be externally validated in future research before the PNI can be used widely as a predictor of RCC patients undergoing nephrectomy.

GNRI Sustainability during One Cycle of First-Line Chemotherapy as a Prognostic Indicator in Patients with Metastatic Urothelial Carcinoma

Mon, 23 Jan 2023 00:00:00 +0000

Oncology. 2023;101(4):224-233. doi: 10.1159/000529203. Epub 2023 Jan 23.

ABSTRACT

INTRODUCTION: This study evaluated the prognostic value of a sustained high Geriatric Nutritional Risk Index (GNRI) during first-line chemotherapy for patients with metastatic urothelial carcinoma (mUC).

METHODS: Between January 2018 and February 2022, 123 patients received platinum-based chemotherapy at Nagoya City University Hospital and affiliated institutions. Of these, 118 eligible patients who showed an Eastern Cooperative Oncology Group performance status (ECOG-PS) between 0 and 2 were retrospectively examined. Based on body mass index and serum albumin levels, GNRI was calculated immediately before and after the first primary chemotherapy cycle. Patients were divided into two groups based on GNRI: GNRI sustained ≥92 in sustainable (n = 63) and GNRI <92 in unsustainable (n = 55) groups, respectively. Clinical outcomes were compared.

RESULTS: No significant differences were noted between the two groups for age, gender, cycle of first-line treatment, and type of series of sequential treatments after failure of first-line therapy. Median overall survival from the start of first-line chemotherapy was 30.2 months (95% confidence interval [CI]: 20.9-NA) for sustainable and 12.6 months (95% CI: 9.0-21.2) for unsustainable groups, respectively (p < 0.05). Multivariate analysis identified ECOG-PS:2 and fatigue, an adverse event, as independent predictors of unsustainable GNRI transition (95% CI: 1.29-90.6, odds ratio [OR]: 10.8; 95% CI: 1.06-26.9, OR: 5.34, respectively).

CONCLUSION: Sustaining a high level of GNRI was an important prognostic indicator in patients with mUC receiving first-line chemotherapy. Appropriate intervention for controlling adverse events, including fatigue, may enhance physical strength during cancer treatment.

The geriatric nutritional risk index predicts complications after nephrectomy for renal cancer

Tue, 13 Dec 2022 00:00:00 +0000

Int Braz J Urol. 2023 Jan-Feb;49(1):97-109. doi: 10.1590/S1677-5538.IBJU.2022.0380.

ABSTRACT

PURPOSE: We examined if malnutrition, as defined by the Geriatric Nutritional Risk Index (GNRI), is independently associated with 30-day postoperative complications in patients undergoing nephrectomy for the treatment of renal cancer.

MATERIALS AND METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program database from 2006-2019, we identified patients ≥65 years old who underwent nephrectomy for renal cancer. The following formula for GNRI was used to define preoperative nutritional status: 1.489 x serum albumin (g/L) + 41.7 x (current body weight [kg]/ ideal body weight [kg]). Based on the GNRI, patients were classified as having no (> 98), moderate (92-98), or severe malnutrition (< 92). After adjusting for potential confounders, multivariable logistic regression analyses were performed to assess the association between GNRI and 30-day postoperative complications. Odds ratios (OR) with 95% confidence intervals (CI) were reported.

RESULTS: A total of 7,683 patients were identified, of which 1,241 (16.2%) and 872 (11.3%) had moderate and severe malnutrition, respectively. Compared to normal nutrition, moderate and severe malnutrition were significantly associated with a greater odds of superficial surgical site infection, progressive renal insufficiency, readmission, extended length of stay, and non-home discharge. Severe malnutrition was also associated with urinary tract infection (OR 2.10, 95% CI 1.31-3.35) and septic shock (OR 2.93, 95% CI 1.21-7.07).

CONCLUSION: Malnutrition, as defined by a GNRI ≤ 98, is an independent predictor of 30-day complications following nephrectomy. The GNRI could be used to counsel elderly patients with renal cancer prior to nephrectomy.

Geriatric Nutritional Risk Index as a Predictor of Prognosis in Metastatic Renal Cell Carcinoma Treated with Nivolumab

Wed, 30 Nov 2022 00:00:00 +0000

Nutr Cancer. 2023;75(2):670-677. doi: 10.1080/01635581.2022.2152061. Epub 2022 Nov 30.

ABSTRACT

BACKGROUND: The Geriatric Nutritional Risk Index (GNRI) has been reported as a screening tool to assess the nutrition-related risk with mortality in older patients and those with the various diseases. However, the prognostic value of GNRI in metastatic renal cell carcinoma (mRCC) patients receiving nivolumab therapy remains unclear.

METHODS: Fifty-six consecutive patients with mRCC receiving nivolumab between September 2013 and August 2020 at our institution were retrospectively analyzed. The survival outcomes and prognostic factors associated with overall survival (OS) were statistically analyzed.

RESULTS: Thirteen and forty-three patients were classified with low (GNRI < 92) and high (GNRI ≥ 92) GNRI, respectively. Patients with low GNRI demonstrated significantly shorter OS (P = 0.0002) than those with high GNRI. In multivariate analysis, GNRI at the time of nivolumab (P = 0.008) was extracted as the predictor for OS in addition to Karnofsky performance status (KPS) (P = 0.016). Integration of the GNRI into the International Metastatic Renal Cell Cancer Database Consortium (IMDC) risk classification improved the c-index from 0.761 to 0.833 (combination of GNRI with IMDC risk classification) and to 0.778 (substitution of GNRI with KPS in IMDC risk classification).

CONCLUSIONS: GNRI was a significant prognostic biomarker in mRCC patients receiving nivolumab.

Impact of the controlling nutritional status (CONUT) score on perioperative morbidity and oncological outcomes in patients with bladder cancer treated with radical cystectomy

Sun, 23 Oct 2022 00:00:00 +0000

Urol Oncol. 2023 Jan;41(1):49.e13-49.e22. doi: 10.1016/j.urolonc.2022.09.023. Epub 2022 Oct 21.

ABSTRACT

INTRODUCTION AND OBJECTIVES: To evaluate the impact of the Controlling Nutritional Status (CONUT) score on perioperative morbidity and oncological outcomes of bladder cancer (BC) patients treated with radical cystectomy (RC).

MATERIALS AND METHODS: We retrospectively analyzed a multi-institutional cohort of 347 patients treated with RC for clinical-localized BC between 2005 and 2019. The CONUT-score was defined as an algorithm including serum albumin, total lymphocyte count, and cholesterol. Multivariable logistic regression analyses were performed to evaluate the ability of the CONUT-score to predict any-grade complications, major complications and 30 days readmission. Multivariable Cox' regression models were performed to evaluate the prognostic effect of the CONUT-score on recurrence-free survival (RFS), overall survival (OS), and cancer-specific survival (CSS).

RESULTS: A cut-off value to discriminate between low and high CONUT-score was determined by calculating the receiver operating characteristic (ROC) curve. The area under the curve was 0.72 hence high CONUT-score was defined as ≥3 points. Overall, 112 (32.3%) patients had a high CONUT. At multivariable logistic regression analyses, high CONUT was associated with any-grade complications (OR 3.58, P = 0.001), major complications (OR 2.56, P = 0.003) and 30 days readmission (OR 2.39, P = 0.01). On multivariable Cox' regression analyses, high CONUT remained associated with worse RFS (HR 2.57, P < 0.001), OS (HR 2.37, P < 0.001) and CSS (HR 3.52, P < 0.001).

CONCLUSIONS: Poor nutritional status measured by the CONUT-score is independently associated with a poorer postoperative course after RC and is predictive of worse RFS, OS, and CSS. This simple index could serve as a comprehensive personalized risk-stratification tool identifying patients who may benefit from an intensified regimen of supportive cares.

Prognostic nutritional index as a prognostic factor for renal cell carcinoma: A systematic review and meta-analysis

Fri, 05 Aug 2022 00:00:00 +0000

PLoS One. 2022 Aug 5;17(8):e0271821. doi: 10.1371/journal.pone.0271821. eCollection 2022.

ABSTRACT

BACKGROUND: Prognostic nutritional index (PNI) is a simple parameter which reflects patient's nutritional and inflammatory status and reported as a prognostic factor for renal cell carcinoma (RCC). Studies were included from database inception until February 2, 2022. The aim of this study is to evaluate prognostic value of PNI by meta-analysis of the diagnostic test accuracy in RCC.

METHODS AND FINDINGS: Studies were retrieved from PubMed, Cochrane, and EMBASE databases and assessed sensitivity, specificity, summary receiver operating characteristic curve (SROC) and area under curve (AUC). Totally, we identified 11 studies with a total of 7,296 patients were included to evaluate the prognostic value of PNI in RCC finally. They indicated a pooled sensitivity of 0.733 (95% CI, 0.651-0.802), specificity of 0.615 (95% CI, 0.528-0.695), diagnostic odds ratio (DOR) of 4.382 (95% CI, 3.148-6.101) and AUC of 0.72 (95% CI, 0.68-0.76). Heterogeneity was significant and univariate meta-regression revealed that metastasis and cut-off value of PNI might be the potential source of heterogeneity. Multivariate meta-regression analysis also demonstrated that metastasis might be the source of heterogeneity.

CONCLUSIONS: PNI demonstrated a good diagnostic accuracy as a prognostic factor for RCC and especially in case of metastatic RCC.

Nutritional Factors during and after Cancer: Impacts on Survival and Quality of Life

Wed, 27 Jul 2022 00:00:00 +0000

Nutrients. 2022 Jul 19;14(14):2958. doi: 10.3390/nu14142958.

ABSTRACT

The French National Cancer Institute conducted a collective expertise study with researchers and clinical experts from the French Network for Nutrition And Cancer Research (NACRe Network). The objective was to update the state of knowledge on the impacts of nutritional factors on clinical endpoints during or after cancer. Data from 150 meta-analyses, pooled analyses or intervention trials and 93 cohort studies were examined; they concerned 8 nutritional factors, 6 clinical events and 20 cancer locations. This report shows that some nutritional factors have impacts on mortality and on the risks of recurrence or second primary cancer in cancer patients. Therefore, high-risk nutritional conditions can be encountered for certain cancer sites: from the diagnosis and throughout the health care pathways, weight loss (lung and esophageal cancers), malnutrition (lung, esophageal, colorectal, pancreatic, gastric and liver cancers), weight gain (colorectal, breast and kidney cancers) and alcohol consumption (upper aerodigestive cancers) should be monitored; and after cancer treatments, excess weight should be detected (colorectal, breast and kidney cancers). These situations require nutritional assessments, and even support or management by health care professionals, in the context of tertiary prevention. This report also highlights some limitations regarding the existing literature and some needs for future research.

Prognostic impact of prognostic nutritional index on renal cell carcinoma: A meta-analysis of 7,629 patients

Mon, 21 Mar 2022 00:00:00 +0000

PLoS One. 2022 Mar 21;17(3):e0265119. doi: 10.1371/journal.pone.0265119. eCollection 2022.

ABSTRACT

BACKGROUND: Prognostic nutritional index (PNI) is a parameter which reflects nutritional and inflammatory status. The prognostic value of PNI in renal cell carcinoma (RCC) remains in debate. The aim of this study is to evaluate the prognostic value and clinicopathological features of PNI in RCC.

METHODS: A literature search was performed in the databases of PubMed, Embase, Web of Science, and Cochrane Library. Hazard ratios (HRs), odds ratios (ORs), and 95% confidence intervals (CIs) were extracted for meta-analysis. The association between PNI and overall survival (OS), cancer-specific survival (CSS), disease-free survival (DFS), progression-free survival (PFS), recurrence-free survival (RFS), and clinicopathological factors were evaluated.

RESULTS: Eleven studies involving 7,629 patients were included for meta-analysis. A decreased PNI was shown to be a significant predictor of worse OS (HR = 2.00, 95%CI = 1.64-2.42, p<0.001), CSS (HR = 2.54, 95%CI = 1.61-4.00, p<0.001), and DFS/PFS/RFS (HR = 2.12, 95%CI = 1.82-2.46, p<0.001) in RCC. Furthermore, a low PNI was correlated with Fuhrman grade III-IV (OR = 1.96, 95%CI = 1.27-3.02, p = 0.002), T stage T3-T4 (OR = 2.21, 95%CI = 1.27-3.87, p = 0.005), presence of sarcomatoid differentiation (OR = 5.00, 95%CI = 2.52-9.92, p<0.001), and presence of tumor necrosis (OR = 3.63, 95%CI = 2.54-5.19, p<0.001).

CONCLUSION: PNI is an independent prognostic indicator of survival and associated with Fuhrman grade, T stage, sarcomatoid differentiation, and tumor necrosis in patients with RCC.

Nutr Cancer. 2022;74(8):2964-2974. doi: 10.1080/01635581.2022.2049829. Epub 2022 Mar 17.

ABSTRACT

To investigate the prognostic value of preoperative prognostic nutritional index (PNI) to predict oncological outcome and intravesical recurrence (IVR) in upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU).

This study involved the clinical data of 255 patients with UTUC who had undergone RNU from 2004 to 2019 at our institution. Patients were grouped according to an optimal value of preoperative PNI. Kaplan-Meier analyses and Cox proportional hazards models were used to analyze the associations of preoperative PNI with progression-free survival (PFS), cancer-specific survival (CSS), overall survival (OS), and IVR.

Patients with low PNI were more likely to be older, have higher tumor stage, higher eGFR, and multifocal lesions. No significant association was found between PNI and CSS, IVR. In subgroup analysis according to the risk stratification, low PNI was associated with worse PFS, CSS, and OS for patients with higher risk. Multivariate analyses showed that elevated PNI was an independent prognostic indicator for PFS (P = 0.014) and OS (P = 0.048).

A low PNI is an independent predictor of PFS and OS in patients with UTUC after RNU. By subgroup analysis, the prognostic value of PNI was limited to patients with higher risk. PNI may become a useful biomarker to predict oncological outcomes in patients with UTUC after RNU.

ABSTRACT

BACKGROUND AND OBJECTIVE: Prostate cancer (PCa) is one of the most common malignant tumors in men. Geriatric Nutritional Risk Index (GNRI) is an objective index for evaluating nutritional status of elderly people over 65 years old. The aim of the current study was to explore the correlation and predictive value between GNRI and postoperative recovery and complications in PCa patients undergoing laparoscopic radical prostatectomy (LRP).

METHODS: Taking 98 as the GNRI boundary value, 96 PCa patients (aged≥65 y) undergoing LRP in the Department of Urology, Affiliated Hospital of North Sichuan Medical College from January 2018 to December 2020 were grouped into malnutrition group (MNg, 34 patients, 35.4%) and normal nutrition group (NNg, 62 patients, 64.6%). Basic information, laboratory examination indexes, operation conditions, postoperative complications and postoperative recovery indexes of patients were recorded and retrospectively analyzed. Clavien-Dindo Classification System (CDCS) was used to assess postoperative complications. T-test was used to analyze differences between the two groups. ROC curve was generated to determine the predictive value of GNRI for postoperative complications.

RESULTS: Percentage of complications was significantly higher in MNg group compared with that in NNg group (P < 0.01). The average grade based on CDCS was significantly lower in NNg group compared with that in MNg group (P < 0.01). Body weight, Body Mass Index (BMI), preoperative hemoglobin value (HGB), serum albumin (ALB) values of MNg and NNg were significantly positively correlated with GNRI (P<0.01). Incidence and severity of postoperative complications of MNg patients were significantly higher compared with those of NNg patients (P<0.05). Average hospitalization cost of MNg patients was higher in MNg patients compared with that of NNg patients (P<0.05). Duration of post-anesthesia care unit (PACU), duration of antibiotic use and duration of indwelling drainage tube were longer in MNg patients compared with those in NNg patients (P<0.05). Furthermore, volume of indwelling drainage tube was higher in MNg patients compared with that in NNg patients (P<0.05).

CONCLUSION: GNRI is an effective and reliable tool for evaluation of preoperative nutritional status of prostate cancer patients. The findings showed that GNRI is correlated with postoperative recovery and complications, and is an effective predictive marker.

Urol Int. 2022;106(6):567-580. doi: 10.1159/000521353. Epub 2022 Jan 24.

ABSTRACT

INTRODUCTION: Prognostic nutritional index (PNI) was indicted as a potential prognostic biomarker for cancer. However, the conclusion remains uncertain for renal cell carcinoma (RCC). This study was to confirm the association of PNI with prognosis and clinicopathological features in RCCs.

METHODS: The PubMed, EMBASE, Cochrane Library, CNKI, and Wan Fang databases were searched to retrieve eligible studies. Hazard ratios (HRs) and 95% confidence intervals (CIs) were pooled to assess the strength of the association.

RESULTS: Fifteen studies were included. The results showed a low pretreatment PNI level was significantly associated with poor overall survival (HR = 1.67, 95% CI: 1.45-1.92), progression-free survival (HR = 1.72, 95% CI: 1.23-2.42), cancer-specific survival (HR = 1.17, 95% CI: 1.09-1.26), disease-free survival (HR = 1.28, 95% CI: 1.09-1.26), and recurrence-free survival (HR = 2.14, 95% CI: 1.38-3.31). This prognostic role of PNI was almost not changed by subgroup analysis based on study design, HR source, RCC type, sample size, cutoff, follow-up, treatment, and country. Furthermore, low PNI was correlated with old age, large tumor size and high T stage, Fuhrman grade, lymph node, and distant metastases.

CONCLUSION: Pretreatment PNI might be a promising indicator to beforehand predict the progression and prognosis for RCC patients.
