Evaluation of PD1 / PDL1 Expression on Blood Cells & Tumor Tissue, Their Role as a Prognostic Target in NSCLC Patients

November 23, 2016 updated by: Oscar Gerardo Arrieta Rodríguez MD, Instituto Nacional de Cancerologia de Mexico

Clinical Pathological Features Associated With the Expression of PD1 / PD-L1 in Subpopulations of Peripheral Blood and Tumor Tissue in Patients With Advanced Non-small Cell Lung Cancer, Their Role as Prognostic and Therapeutic Targets

Several reports have examined Programmed Death 1 (PD-1) expression on tumor-infiltrating T-cells, and its correlation with prognosis has been discussed. However, Programmed Death 1 (PD1)/Programmed Death Ligand 1 (PDL1) expression on the peripheral blood T-cells of cancer patients, particularly in those with lung cancer, has not been sufficiently studied. The purpose of this study is evaluate the expression of PD1 and PDL1 in subpopulations of peripheral blood and tumor cells patients with lung cancer non-small cell (NSCLC), associating with clinicopathological features of the patients studied.

Detailed Description

This is a prospective cohort study including patients with NSCLC stages IIIA, IIIB and IV lung cancer clinic of the National Cancer Institute (INCAN)

Clinical samples. Prior and informed consent before receiving any treatment, sample be obtained 15 ml peripheral blood of each subject included in the study (patients and controls). mononuclear peripheral blood cells (PBMC) from different groups of subjects separated by centrifugation gradient (Polymorphprep, Accurate Chemical) are used. The cells are resuspended in dimethylsulfoxide (DMSO) and 10% fetal bovine serum (FBS) to 90% at a concentration of 1 million cells per ml and kept in liquid nitrogen until use.

Evaluation of PD-1, PD-L1 by flow cytometry. The following monoclonal antibodies directed against cell surface antigens of human are used: anti-PD-1, anti-PD-L1, anti-PD-L2, anti- cluster of differentiation (CD) 3, anti-CD4, anti-CD8, anti-CD14, anti-CD16, anti-CD56, anti-CD19, anti-CD20.

Immunolocalization of PD-1, PD-L1 in lung tumor tissue of patients with NSCLC. Immunohistochemical staining (IHC). Lung biopsy is obtained paraffin blocks, and are processed by IHC technique for antitumor expression of PD1 / PDL1.V PD-L1 immunostaining was classified into two groups according to intensity and extent: (a) negative, when no staining or positive staining was detected in <5% of the cells; and (b) positive, when membranous staining was present in P5% of the cells.
