A preliminary study on natural killer activity in0 patients with gynecologic malignancies

Summary

A release assay of125IUdR-labelled K562 cells as target cells was performed for measuring natural killer (NK) activity of mononuclear cells in the peripheral blood of 92 cases, including 42 healthy women, 22 patients with gynecological benign tumors, and 28 patients with gynecological malignancies. The NK activity of malignant tumor group was obviously lower than that of healthy women and of benign tumor group, suggesting that a defective NK activity was present in the patients with gynecological malignancies. The NK activity in patients with ovarian malignant tumors was much lower than in those with cervical cancer, the difference being of statistical significance. In this study the leukocyte interferon was investigated for its effects on the NK activity of peripheral blood mononuclear cells from 4 cases of gynecological malignancies. The level of NK activity ascended significantly in every case nearly to normal. The augmentation of NK activity by interferon may be used as a new immunotherapy for gynecological malignancies.
