Ovarian cancer: a solid tumor with evidence of normal cellular immune function but abnormal B cell function.
Immunologic assays of B and T lymphocyte function were performed on 21 patients with epithelial ovarian cancer prior to either chemotherapy or radiotherapy. The results were compared to similar studies on 12 age-matched normal women. The total peripheral blood lymphocyte counts, proportion of E rosette positive cells, stimulation of T cells by phytohemagglutinin and concanavalin A, recall skin tests, and the ability to have a primary delayed hypersensitivity response to keyhold limpet hemocyanin did not differ between patients and controls. However, patients with ovarian cancer had statistically significant reduction in surface immunoglobulin positive cells, proliferative response to pokeweed mitogen and primary antibody response to keyhole limpet hemocyanin. In contrast to results in patients with other solid tumors, these data indicate that untreated patients with ovarian cancer have evidence of normal cellular immune function but abnormal B cell function.
