PD-L1 expression in greater than or equal to 5% tumor-infiltrating immune cells (IC: lymphocytes, macrophages, dendritic cells, and granulocytes) determined by VENTANA PD-L1 (SP-142) assay in urothelial carcinoma tissue is associated with increased objective response rate (ORR) in a non-randomized study of TECENTRIQ (atezolizumab). Interpretation was based on guidelines published by the manufacturer, which defines a PD-L1 protein expression as the proportion of tumor area occupied by PD-L1 expressing tumor-infiltrating immune cells of any intensity.

FFPE: State any other type of fixative used.
A pathology report which includes the paraffin block number, and both
macroscopic and microscopic evaluation and diagnosis, should be sent
with the specimen.
