Radical cystectomy for locally advanced urothelial carcinoma of the urinary bladder: Health-related quality of life, oncological outcomes and predictors for survival.

Purpose: While survival outcomes of locally advanced bladder cancer patients undergoing radical cystectomy are known to be poor, less is known regarding patient-reported outcomes and predictive features for survival in this patient subgroup.

Methods: One hundred and eighteen consecutive patients with pT4a cM0 urothelial carcinoma of the bladder were included. Based on pathological review, patients were stratified into 3 subgroups based on existence of additional lesions and invasion depth of the respective lesions. Cancer-specific survival and overall survival (OS) was determined using Kaplan-Meier-analyses and multivariate Cox regression models (P <0.05). Health-related quality of life was assessed using the validated EORTC-QLQ-C30 questionnaire pre- and postoperatively.

Results: Seventy-two (61.0%) patients were ineligible for neoadjuvant chemotherapy. Median follow-up based on censored patients was 12 months. Twelve month OS rate was 56.1%, 24 months OS rate was 21.1%. A total of 44.4% of the patients stated good general health-related quality of life. In multivariate analysis, we found significantly adverse OS outcomes for female patients (hazard ratio 2.35, 95% confidence interval 1.09-5.08, P = 0.030). Patients with at least 1 additional locally advanced tumor had significantly worse OS outcomes compared to patients who had no additional lesions in multivariate Cox regression analysis (hazard Ratio 3.37, 95% confidence interval 1.29-8.78, P = 0.013).

Conclusion: Existence of multiple locally advanced lesions and female gender is an independent predictor of worse survival outcomes in patients with pT4a urothelial carcinoma undergoing radical cystectomy.
