TECENTRIQ is the first FDA-approved anti-PD-L1 cancer immunotherapy which is indicated for the treatment of patients with metastatic non-small cell lung cancer (NSCLC) who have disease progression during or following platinum-containing chemotherapy. Determining a patient's PD-L1 expression level can provide insight into the survival benefit that may be achieved from treatment with TECENTRIQ. PD-L1 expression in >=50% tumor cells (TC) or >= 10% tumor-infiltrating immune cells (IC): lymphocytes, macrophages, dendritic cells, and granulocytes determined by VENTANA PD-L1 (SP-142) Assay/Quest PD-L1 Lung (Atezolizumab) in non-small cell lung cancer tissue may be associated with enhanced overall survival from TECENTRIQ (atezolizumab).

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.
