Summary
Brief summary (as posted)
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.

- Evaluation of PD-1/PDL-1 expression. Evaluate the expression of PD-1 / PD-L1 on T-cell subpopulations (CD3 + (CD4 +, CD8 +), B cells (CD19 + CD20 +), natural killer (NK) cells (CD16 + CD56 +) NK T-cells (CD3 + CD16 + CD56 + ) peripheral blood samples in 150 NSCLC, free treatment by flow cytometry. Evaluate the expression of PD-1 / PD-L1 in tumor tissue obtained by biopsy of patients with NSCLC by immunohistochemistry. The patients for the enrollment have to be diagnosed with advanced Non-Small Cell Lung Adenocarcinoma (clinical stages IIIA, IIIB and IV), treated at the Instituto Nacional de Cancerología (INCan) who had not received radiotherapy and / or chemotherapy prior to obtaining samples to analyze. ECOG performance status 0-2 and present evidence of measurable disease.
