[Natural killer activity and sensitization of the lymphocytes to tissue antigens in lung cancer].

A decreased natural killer activity was observed in patients with lung cancer as the disease progressed. Surgical intervention results in its elevation at the IIId stage, while the application of cytostatics or irradiation are efficient at the IIId and IInd stages. Pronounced sensibilization of the peripheral blood lymphocytes in cancer patients to normal and cancer tissue antigens was demonstrated with the help of the leukocyte adhesion inhibition test.
