title: [Cytolytic activity of mononuclear cells, T-lymphocytes and monocytes of the peripheral blood in patients with lung cancer].
abstract: A comparative analysis of cytotoxic activity of mononuclear cells (MNC) from peripheral blood, T-lymphocytes and monocytes from patients with lung cancer has been performed. It has been shown that in 27% of cases MNC, T-lymphocytes and monocytes lyse freshly isolated autologous and allogenic tumor cells. In all the patients examined the effector cells were active in respect to culture cell line of lung adenocarcinoma (ACL). The decrease in NK activity of the cell population enriched by T-lymphocytes in comparison to the control group (p less than 0.05) was noticed. MNC and T-lymphocytes, in contrast to monocytes, had high killer activity identified by lectin-dependent cytotoxicity technique. The activity of the effector cells does not depend on the morphological structure of the tumor, but decreases with the disease progression. The results of the experiments show that in patients with lung cancer peripheral blood lymphocytes and monocytes are essential, independently functioning effectors involved in antitumor defense.
