Treatment patterns and clinical outcomes in metastatic urothelial carcinoma: a German retrospective real-world analysis.

This study assessed real-world treatment in patients with metastatic urothelial carcinoma (mUC) in Germany. Patients diagnosed with mUC from 2015 to 2019 were identified in two claims databases: AOK PLUS and GWQ. 3226 patients with mUC were analyzed; 1286 (39.9%) received systemic treatment within 12 months of diagnosis (platinum-based chemotherapy: 64.2%). Factors associated with receiving treatment were: younger age, male sex, less comorbidity and recent diagnosis. In AOK PLUS and GWQ populations, unadjusted median overall survival (interquartile range) from diagnosis in treated patients was 13.7 (6.8-32.9) and 13.8 (7.1-41.7) months, and in untreated patients was 3.0 (1.2-10.8) and 3.6 (1.2-18.8) months, respectively. A significant proportion of patients with mUC in Germany receive no systemic treatment.
