Real-world outcomes in locally advanced or metastatic urothelial carcinoma following platinum and PD-1/L1 inhibitor therapy

Abstract

Aim: To investigate real-world overall survival (rwOS) and real-world progression-free survival (rwPFS) in locally advanced/metastatic urothelial carcinoma postplatinum and postprogrammed death receptor-1/death ligand 1 inhibitors. Patients & methods: Adult patients diagnosed with locally advanced/metastatic urothelial carcinoma from 1 January 2011 to 31 December 2018 and treated with taxane monotherapy or any therapy postplatinum and post-PD-1/L1 inhibitors were included from a nationwide electronic health record-derived oncology database. Results: Median rwOS among 72 patients treated with taxane monotherapy was 7.6 months (95% CI: 5.2-14.4) and rwPFS was 2.9 months (95% CI: 2.4-4.0). Among 208 patients treated with any therapy, median rwOS was 8.9 months (95% CI: 7.3-10.6) and rwPFS was 3.6 months (95% CI: 2.7-4.7). Conclusion: Short duration of rwOS and rwPFS were observed, highlighting the need for effective and safe treatments in this patient population.
