Purpose: The Malnutrition Universal Screening Tool integrates body mass index, unintentional weight loss and present illness to assess risk for malnutrition. The predictive role of ‘MUST’ among patients undergoing radical cystectomy is unknown. We investigated the role of ‘MUST’ in predicting postoperative outcomes and prognosis among patients after RC. Materials and methods: We conducted a multicenter retrospective analysis of 291 patients who underwent radical cystectomy in 6 medical centers between 2015 and 2019. Patients were stratified to risk groups according to the ‘MUST’ score [low risk (n = 242) vs. medium-to-high risk (n = 49)]. Baseline characteristics were compared between groups. Endpoints were 30-day postoperative complications rate, cancer-specific-survival and overall survival. Kaplan-Meier curves and Cox-regression analyses were used to evaluate survival and identify predictors of outcomes. Results: Median age of the study cohort was 69 years (IQR 63–74). Median duration of follow up for survivors was 33 months (IQR 20–43). Thirty-day major postoperative complications rate was 17%. Baseline characteristics were not different between the ‘MUST’ groups, and there was no difference in early post-operative complication rates. CSS and OS were significantly lower (p ≤ 0.02) in the medium-to-high-risk group (‘MUST’ score≥1) with estimated 3-year CSS and OS rates of 60% and 50% compared to 76% and 71% in the low-risk group, respectively. On multivariable analysis, ‘MUST’≥1 was an independent predictor of overall- (HR = 1.95, p = 0.006) and cancer-specific-mortality (HR = 1.74, p = 0.05). Conclusions: High ‘MUST’ scores are associated with decreased survival in patients after radical cystectomy. Thus, the ‘MUST’ score may serve as a preoperative tool for patient selection and nutritional intervention.
