✦ Synopsis

Natural killer (NK) cell activity and antibody dependent cell-mediated cytotoxicity (ADCC) was measured in 62 untreated cervical carcinoma patients and 25 normal healthy women, using a short-term chromium release assay. A significant reduction in NK and ADCC activity was observed in disseminated disease than in localized disease, when compared with normal donors. The majority of the patients received radiotherapy and both NK and ADCC activity recovered after therapy. Furthermore, interferon-alpha was demonstrated to augment NK activity of peripheral blood mononuclear cells from healthy donors as well as patients. Also large granular lymphocytes separated on Percoll density gradient were the same in number in both the populations studied, although in cervical cancer there seemed to be a defect in killing activity.
