β¦ Synopsis
The effect of surgery on peripheral blood mononuclear cell responsiveness to mitogens and supressor cell (SC) activity assessed in a concanavalin A (ConA) assay were studied in patients with stage 0 and stage HI-IV cancer. Patients were exposed to a similar surgical trauma the same type of anaesthesia, and to no pre-and early postoperative radio-or chemotherapy. A more pronounced postoperative decrease in the lymphocyte count, responsiveness to phytohemagglutinin (PHA) and ConA, and in the SC activity was found in the nonadvanced than advanced cancer group. These findings point to an impaired mobilization and distribution capacity of circulating lymphocytes in patients with advanced neoplastic disease.

Blood lymphocytes from 10 untreated patients with active Hodgkin's disease were compared with those of 10 cured patients with regard to the responsiveness of the cells to PHA and Con A following in vitro irradiation. Lymphocytes of patients remaining in long-term remission exhibited the same pattern
