The Importance of Ventana PD-L1 (SP142) Assay in Bladder Cancer Treatment

Ventana PD-L1 (SP142) assay approved by FDA in 2016, is a laboratory test for PD-L1 status assessment in bladder cancer patients.  

Patients whose bladder cancer has high PD-L1 expression may have better response to PD-L1 blockers than patients with lower or no PD-L1 expression.

Determination of PD-L1 status may help physicians to make an informed decision on prescribing atezolizumab (PD-L1 blocker) for urothelial cancer treatment.
