Contemporary Survival Rates for Muscle-Invasive Bladder Cancer Treated With Definitive or Non-Definitive Therapy

INTRODUCTION: Definitive, curatively intended therapy for muscle-invasive bladder cancer can be associated with significant morbidity and adverse effects on quality of life, leaving patients reluctant to opt for these interventions. We sought to provide perspective to patients and clinicians exploring therapy options.

MATERIALS AND METHODS: We examined stage-by-stage overall survival of definitive therapy (DT) (either radical cystectomy in conjunction with neoadjuvant chemotherapy or trimodal therapy) versus non-DT (including palliative transurethral resection, chemotherapy and radiation treatment) among 42,144 patients within the National Cancer Database (2004-2012).

RESULTS: The median overall survival stratified by receipt of DT versus non-DT was 45.3 versus 16.4 months, 26.7 versus 9.6 months, and 21.2 versus 7.5 months in American Joint Committee on Cancer stages II, III, and IV, respectively. In multivariable Cox regression analysis, DT conferred a significant survival benefit in all stages, most pronounced in American Joint Committee on Cancer stage IV (hazard ratio, 0.46; 95% confidence interval, 0.43-0.49; P < .001).

CONCLUSION: Despite potentially significant morbidity and adverse effects on quality of life, DT is associated with a sizable survival benefit.
