Aim: Investigate the effectiveness of chemotherapy for first-line (1L) treatment of metastatic bladder cancer (mBC). Methods: Retrospective cohort study evaluating treatment patterns/outcomes in 1155 mBC patients receiving initial treatment in the community practice setting from January 2010 to June 2014, and followed through July 2016. Results: The most commonly utilized 1L and second-line (2L) regimens were platinum-based and taxane-based, respectively. Median (95% CI) OS for all patients from 1L initiation was 12.8 months (11.7–14.6), and median OS for all 2L regimens was 9.4 months (8.2–11.1). Conclusion: mBC patients eligible for and who received cis-based regimens experienced better OS results. Poor renal function was a key driver of cis-ineligibility. The various monotherapy and combination chemotherapy regimens in 2L produced relatively short OS outcomes.
