Multiple immunologic parameters were studied in three patients prior to and after hyperthermia treatment for disseminated malignancy. Two patients had malignant melanoma and received chemotherapy during the hyperthermia treatment. One had adenocarcinoma of the stomach and received no concomitant chemotherapy. Rapid rosettes as a measure of thymus-derived lymphocytes (T-lymphocytes) were found to increase significantly after therapy (P less than 0.05) both in percentage and absolute numbers. There was no change in the numbers or percentages of other markers for T-lymphocytes or bone marrow-derived B-lymphocytes. Complement profiles revealed a significant decrease in C3 (P less than 0.005) after hyperthermia but no change in levels of other components of the alternate pathway. Antibody-dependent lymphocyte-mediated cytotoxicity and polymorphonuclear cell-mediated antibody-dependent cytotoxicity were also depressed after hyperthermia. No change was observed in immunoglobulin levels with hyperthermia therapy. Results indicated that hyperthermia may favorably alter the immune balance between tumor and host in selected instances.
