- W2947567038 abstract "e16029 Background: Radical cystectomy is the guideline-recommended treatment for muscle-invasive bladder cancer; however, use of trimodal therapy, which utilizes a combination of surgery, radiation, and chemotherapy, has increased in recent years with conflicting survival outcomes. Methods: Utilizing data from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database, a total of 2,963 patients aged 66 years or older diagnosed with clinical stage T2-4a bladder cancer from January 1, 2002 to December 31, 2011 were analyzed. Conventional regression, propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) were used to compare radical cystectomy and trimodal therapy for overall and cancer-specific survival, and cost. Results: Patients who underwent TMT had significantly decreased overall (conventional regression: Hazard Ratio (HR) 1.54, 95% Confidence Interval (CI), 1.39-1.71; PSM: HR 1.49, 95% CI 1.31-1.69; IPTW: HR 1.54, 95% CI 1.39-1.71) and cancer-specific (conventional regression: HR 1.51, 95% CI 1.40-1.63; PSM: HR 1.55, 95% CI 1.32-1.83; IPTW: HR 1.51, 95% CI 1.40-1.63) survival. Median total costs were significantly higher with trimodal therapy than with radical cystectomy at 6-month ($171,401 vs. $99,890, p < 0.001). Conclusions: Using population-based data and different analytic methods to control for imbalance between study groups, we found that trimodal therapy was associated with decreased overall and cancer-specific survival at increased costs compared to radical cystectomy." @default.
