Abstract
BACKGROUND: Female patients undergoing radical cystectomy (RC) for bladder cancer have historically presented with more advanced disease and poorer survival outcomes than males. These disparities have been attributed to biological differences, delayed diagnosis, and variations in treatment delivery. Recent data suggest, however, that outcomes may converge when patients are managed in standardized, multidisciplinary, high-volume centers. This study evaluated the influence of gender on perioperative features and oncological outcomes such as disease-free survival (DFS), disease-specific survival (DSS), and overall survival (OS) at a tertiary uro-oncology center. METHODS: We retrospectively reviewed a prospectively maintained database of patients who underwent open or robotic-assisted RC for histologically confirmed urothelial carcinoma between 2014 and 2023 at Guy's and St. Thomas' NHS Foundation Trust. Demographic, perioperative, and pathological variables were stratified by gender to assess their association with DFS, DSS, and OS. RESULTS: A total of 887 patients were included: 640 men (72.2%) and 247 women (27.8%), with similar mean age (68.5 vs. 68.1 years) and tumour histology (pure urothelial carcinoma 85% vs. 83%). Men had a higher prevalence of diabetes and chronic kidney disease, but no significant differences were observed in time from referral to surgery (0.93 vs. 1.03 months, p = 0.93), use of neoadjuvant therapy (21.6% vs. 17.3%, p = 0.25), or surgical approach (p = 0.55). Pathological stage distribution was comparable between sexes (pT0-1: 44% vs. 50%; pT2-4: 56% vs. 50%; p = 0.13). Kaplan-Meier analysis revealed no significant gender-related differences in 12-month DFS (77.3% vs. 75.4%, p = 0.20), DSS (85.6% vs. 86.9%, p = 0.56), or OS (81.2% vs. 85.2%, p = 0.70). CONCLUSION: In this high-volume tertiary center, gender did not independently influence perioperative or survival outcomes following radical cystectomy. These findings suggest that standardized, multidisciplinary management within specialized bladder cancer pathways may mitigate the pathological and survival disparities historically associated with gender.
