Purpose: To examine the overall and stage-specific age-adjusted incidence, 5-year survival and mortality rates of bladder cancer (BCa) in the United States, between 1973 and 2009. Materials and methods: A total of 148,315 BCa patients were identified in the Surveillance, Epidemiology and End Results database, between years 1973 and 2009. Incidence, mortality, and 5-year cancer-specific survival rates were calculated. Temporal trends were quantified using the estimated annual percentage change (EAPC) and linear regression models. All analyses were stratified according to disease stage, and further examined according to sex, race, and age groups. Results: Incidence rate of BCa increased from 21.0 to 25.5/100,000 person-years between 1973 and 2009. Stage-specific analyses revealed an increase incidence for localized stage: 15.4-20.2 (EAPC: +0.5%, p < 0.001) and distant stage: 0.5-0.8 (EAPC: +0.7%, p = 0.001). Stage-specific 5-year survival rates increased for all stages, except for distant disease. No significant changes in mortality were recorded among localized (EAPC: -0.2%, p = 0.1) and regional stage (EAPC: -0.1%, p = 0.5). An increase in mortality rates was observed among distant stage (EAPC: +1.0%, p = 0.005). Significant variations in incidence and mortality were recorded when estimates were stratified according to sex, race, and age groups. Discussion: Albeit statistically significant, virtually all changes in incidence and mortality were minor, and hardly of any clinical importance. Little or no change in BCa cancer control outcomes has been achieved during the study period. (C) 2013 Elsevier Ltd. All rights reserved.
