Effect of Age on Cancer-specific Mortality in Patients With Urothelial Carcinoma of the Urinary Bladder: A Population-based Competing-risks Analysis Across Disease Stages

The objective of the study is to test the effect of age on cancer-specific mortality (CSM) in patients with urothelial carcinoma of the urinary bladder (UCUB), across all disease stages. Materials and Methods: Within the Surveillance, Epidemiology, and End Results (SEER) registry (2004-2016), we identified 207,714 patients. Age was categorized as: below 60 versus 60 to 69 versus 70 to 79 versus 80 years and above. Multivariable competing-risks regression (CRR) models were used according to disease stage (low-risk nonmuscle invasive: TaN0M0 low grade, high-risk nonmuscle invasive: Ta high grade or Tis-1N0M0, muscle invasive: T2-3N0M0, regional: T4N0M0/TanyN1-3M0, and metastatic: TanyNanyM1). Results: Overall, 33,970 (16.4%) versus 52,173 (25.1%) versus 64,537 (31.1%) versus 57,034 (27.4%) patients were below 60 versus 60 to 69 versus 70 to 79 versus 80 years and above, respectively. In multivariable CRR models that focused on low-risk nonmuscle invasive UCUB, advanced age was associated with higher CSM rates (hazard ratio [HR]: 7.04 in patients aged 80 y and above, relative to below 60 y; P
