Purpose: The Geriatric Nutritional Risk Index (GNRI) is a simple screening tool to predict nutrition-related risk of morbidity and mortality in older patients. We assessed whether preoperative GNRI was associated with 30-day complications after radical cystectomy (RC). Materials and Methods: Using the American College of Surgeons National Surgical Quality Improvement Program database, we identified patients 65 years or older who underwent RC for the treatment of bladder cancer between 2007 and 2019. Patients were dichotomized into at-risk (GNRI 98) or no-risk (GNRI >98) groups. Using propensity score matching, the 2 groups were compared for baseline differences and 30-day outcomes. We evaluated GNRI as an independent predictor of postoperative complications using multivariable logistic regression analysis. Results: We identified 2,926 patients eligible for analysis. After propensity score matching, patients in the at-risk GNRI group had higher rates of any complication (p[0.017), blood transfusion (p[0.002), extended length of stay (p[0.004) and nonhome discharge (p <0.001). Multivariable logistic regression analysis revealed that a decreasing GNRI is an independent prognostic factor for mortality (OR 1.05, 95% CI 1.01e1.08, p[0.009), blood transfusion (OR 1.03, 95% CI 1.02e1.04, p <0.001), pneumonia (OR 1.04, 95% CI 1.01e1.07, p[0.013), extended length of stay (OR 1.03, 95% CI 1.02e1.05, p <0.001) and nonhome discharge (OR 1.04, 95% CI 1.03e1.06, p <0.001). Conclusions: We demonstrate that nutritional status evaluated by GNRI predicts 30-day complications after RC.

Treatment of renal angiomyolipoma (AML) seeks to reduce related complications and preserve kidney function. The purpose of this article was to perform an updated literature review on the diagnosis, therapeutic options, and criteria for invasive intervention in patients with renal AML. Computerized tomography is the standard diagnostic method for renal AML, while definitive diagnosis is made by histopathology. The management of choice in most cases is active surveillance (AS), with a clinical and imaging follow-up protocol. In high-risk cases, therapeutic management should be considered, with alternatives such as selective arterial embolization (SAE), nephron-sparing surgery (NSS), and mTOR inhibitors in selected patients. Renal AML in women of childbearing age, those with growth >0.25 cm/year, intralesional aneurysms >5 mm, and clinically significant symptoms may qualify for active treatment. Despite the limitations derived from the available evidence, it is possible to consider SAE, NSS, and the use of mTOR inhibitors as management alternatives for selected patients.

While studies have demonstrated an association between preoperative hypoalbuminemia and adverse clinical outcomes, the optimal serum albumin threshold for risk-stratification in the broader surgical population remains poorly defined. We sought define the optimal threshold of preoperative serum albumin concentration for risk-stratification of adverse post-operative outcomes. Using the American College of Surgeons National Surgical Quality Improvement Program Database, we identified 842,672 patients that had undergone a common surgical procedure in one of eight surgical specialties. An optimal serum albumin concentration threshold for risk-stratification was determined using receiver-operating characteristic analysis. Multivariable logistic regression analysis was used to evaluate the odds of adverse surgical events; a priori defined subgroup analyses were performed. A serum albumin threshold of 3.4 g/dL optimally predicted adverse surgical outcomes in the broader cohort. After multivariable analysis, patients with hypoalbuminemia had increased odds of death within 30 days of surgery (odds ratio [OR] 2.01, 95% confidence interval [CI] 1.94–2.08). Hypoalbuminemia was associated with greater odds of primary adverse events among patients with disseminated cancer (OR 2.03, 95% CI 1.88–2.20) compared to patients without disseminated cancer (OR 1.47, 95% CI 1.44–1.51). The standard clinical threshold for hypoalbuminemia is the optimal threshold for preoperative risk assessment.

Background To stratify 10‐year survival outcomes by degree of social disparities in pediatric Wilms' tumor patients. We applied the Social Deprivation Index (SDI) to survival outcomes from the national SEER database to elucidate the effects of lower socioeconomics on cancer survival. Methods A retrospective cohort study was performed using the national Surveillance, Epidemiology, and End Results (SEER) oncology registry from 1975 to 2016 based on county‐level data. Pediatric patients (<18 years old) with a diagnosis of WT (C64.9) and confirmed based on histology codes (8960/8963) were included. SDI scores were calculated for each patient and initially divided into quintiles. Patients were delineated into high‐risk (>60th percentile/more deprived) or low‐risk (<60th percentile/less deprived) groups. Statistics were assessed using Fisher's exact test, Student's t ‐test, and Kaplan–Meier assessed survival differences with log‐rank test for trend. Results A total of 3406 patients were included with 1366 patients reported in the high‐risk group and 2040 patients in the low‐risk group. Quintile data demonstrated a stratification in survival based on socioeconomic status. Patients in more socially deprived counties were significantly ( p = 0.035) more likely to have worse overall survival compared with those living in less deprived areas at 10‐year (87.3% vs 89.3%) follow‐up. Conclusions 10‐year overall and cancer‐specific survival data for patients with Wilms' tumor stratify by socioeconomic lines. This represents an area that needs to be addressed in this pediatric oncologic population. Patients from more socially deprived areas have significantly worse 10‐year overall survival rates and noticeably different 10‐year cancer‐specific survival rates.
