RESUMO
AIM: To study the expression of the programmed cell death receptor (PD-1) and its ligand (PD-L1) by immunocompetent cells in endometrial cancer patients with metabolic disorders. MATERIALS AND METHODS: Populations and subpopulations of lymphocytes were analyzed by flow cytometry. Antibodies against CD279 were used to detect PD-1 on the CD4+ and CD8+ T cells. Antibodies against CD14 and CD274 were used to detect PD-L1 on monocytes. RESULTS: In patients with severe metabolic disorders, the expression of PD-1 on CD8+ and CD4+ lymphocytes and the expression of the corresponding PD-L1 on CD14+ cells before treatment and after radiation therapy were higher than in the control group. CONCLUSION: Theincreased expression of PD-1 and PD-L1 receptors by immunocompetent cells can be considered a new prognostic marker in endometrial cancer patients with morbid obesity.
