Bladder cancer in Ireland: a 21-year review.

ABSTRACT

INTRODUCTION: Bladder carcinoma is one of the most commonly diagnosed cancers worldwide; however, various studies have reported on marked international variation in incidence and mortality rates. The aim of this study was to report national figures on incidence, survival and risk factors of bladder cancer. This retrospective review is the first to offer a comprehensive analysis of incidence rates, mortality and potential risk factors in the Irish population from 1994 to 2015. METHODS: This was a retrospective study of incidence and survival trends in bladder cancer in the Irish population from 1994 to 2014 based on data from the National Cancer Registry of Ireland (NCRI). Patient demographics, pathology and survival data, as well as potential contributing factors, were studied. RESULTS: A total of 9656 cases of bladder cancer were diagnosed from 1994 to 2015, with majority of cases occurring in males (71%). Survival decreased with increasing age, higher grade and higher stage. Bladder cancer is more common in those with a smoking history and with a higher deprivation score. Urothelial cell carcinoma was the most common pathology (95%), with the majority of patients being stage 1 or 2 (44.7%). CONCLUSION: The overall incidence of bladder cancer in Ireland has fallen, in line with reducing smoking rates. Our data reflects international trends in incidence, survival and contributing risk factors.
