Second Primary Cancer After Bladder Cancer: A Comprehensive Analysis of a National Cancer Registry

Original language description

BACKGROUND: Bladder cancer (BC) is one of the most common cancers and many patients will experience long-term survival. Non-urothelial second primary cancers (SPC) relatively frequently occur in the population of BC survivors. METHODS: Czech National Cancer Registry was the principal data source for this study. The risk of development of non-urothelial SPC after BC was assessed by the standardized incidence ratio (SIR). The standardized mortality ratio (SMR) was utilized to determine the risk of death from SPC following BC. RESULTS: Of the total of 61,314 patients with BC, a cohort of 12,645 survivors diagnosed with a SPC were analyzed. Compared to the general population, the SIR of neoplasia was significantly increased in BC survivors, with a SIR of 1.75 (95% confidence interval [CI] 1.72-1.78) for all cancers, especially during the first 5 years after BC diagnosis. The SMR was increased in BC survivors (1.25; 95% CI 1.21-1.29) for all cancers. Lung cancer frequently occurred as a SPC and was associated with high mortality in BC survivors. BC survivors also had a higher risk of laryngeal cancer and other cancers known to be strongly associated with smoking, but also of soft tissue tumors, colorectal cancer, chronic lymphocytic leukemia, and thyroid cancer. CONCLUSIONS: The present large registry-based study shows that BC survivors have a significantly higher risk of being diagnosed with another primary cancer compared to the general population, especially during the first 5 years after BC diagnosis. In addition to smoking-related cancers, increased incidence of some cancers not known to be associated with smoking was observed.
