Temporal Trends and Cancer-Specific Mortality in Nonmetastatic Muscle-Invasive Urothelial Carcinoma of the Urinary Bladder Treated With Trimodal Therapy.

Trimodal therapy (TMT) is guideline-recommended for the management of organ confined urothelial carcinoma of urinary bladder (UCUB). However, temporal trends in TMT use and cancer-specific mortality free-survival (CSM-FS) between historical TMT versus contemporary TMT have not been assessed. We addressed this knowledge gap.

Within the Surveillance, Epidemiology, and End Results database (2004-2020), we identified nonmetastatic UCUB patients with cT2-T4aN0-N2 treated with TMT, defined as the combination of transurethral resection of bladder tumor, chemotherapy and radiotherapy. Temporal trends described TMT use over time. Subsequently, patients were divided between historical (2004-2012) versus contemporary (2013-2020) cohorts. Survival analyses consisting of Kaplan-Meier plots and multivariable Cox regression (MCR) models addressed CSM-FS. Separate analyses addressed patients with organ confined (OC: cT2N0M0) versus nonorgan confined (NOC: cT3-4a and/or cN1-2) clinical stages.

Of 4,097 assessable UCUB TMT patients, 1744 (43%) were treated in the historical period (2004-2012) versus 2353 (58%) in the contemporary period (2013-2020). TMT use increased over time in OC patients (EAPC:+3.4%, P < .001), as well as in NOC (EAPC:+2.7%, P < .001). In OC stage, median CSM-FS was 55.3% in historical versus 49.0% in contemporary patients (HR:0.75, P < .001). Similarly, in NOC stage, 5-year median CSM-FS was 43.0% in historical versus 32.8% in contemporary patients (HR:0.78, P = .01).

TMT rates have increased over time in both OC and NOC patients. Contemporary TMT patients benefit of better cancer-specific survival. Interestingly, this benefit applies equally to OC and NOC TMT-treated patients.
