Prevalence of PD-L1 Expression in Patients With Advanced Urothelial Carcinoma

Brief description of study

The purpose of this study is to assess the prevalence of pre-treatment tumor tissue PD-L1 expression in patients diagnosed with advanced urothelial carcinoma.

Detailed Study Description

Advanced urothelial carcinoma (UC) (locally advanced/unresectable or metastatic UC) is a fatal disease with 5-year survival rate of 5%. The most frequently studied diagnostic for advanced UC is the programmed death-ligand 1 (PD-L1) protein expression in tumor tissue. A better understanding of PD-L1 expression in a "real world" setting could help understand its clinical utility in the management and decision making in advanced UC and clinical trial design.
