Lymphocyte cytotoxicity against allogeneic cultured cells in gynecologic malignancy.
Peripheral blood lymphocytes from patients with gynecologic cancer were tested by micro-cytotoxicity assay against two types of allogeneic cultured cancer cell lines: squamous cell carcinoma and adenocarcinoma. Lymphocytes from cancer patients with squamous cell carcinoma or adenocarcinoma were equally cytotoxic against these target cells. In addition, lymphocytes from healthy controls and myoma patients were also cytotoxic for these cell lines. No significant difference in cytotoxic activities was detected among the cancer patients and controls. However, a good correlation was observed between cytotoxic activity and non-specific lymphocyte responses. It was concluded that this assay sysetm is not suitable for measuring cell-mediated immunity against tumor specific antigens but does estimate non-specific resistance against cancer.
