title: [A multi-institutional study on postoperative adjuvant immunochemotherapy of gastric cancer].
abstract: An analysis of 3,630 gastric cancer cases from 412 institutions who were treated with 6 randomly-assigned protocols was carried out to study the effect of daily PSK and Futraful administration and the adjuvant effect of PSK and/or Picibanil (OK 5 KE) combined with MMC and FT. Evaluation of immunochemotherapy was made on the basis of three-year survival rates and immunoparameters. The most positive results were found in survival rates favoring the combined therapy (FT + PSK) over single administration (FT) to relatively early-stage patients (30%, difference), PSK, MMC and FT combination (10%), and PSK, OK, MMC and FT (22%), over single chemotherapy alone. Serum alpha-2 globulin levels, indicative of immunosuppression, were lower in PSK-administered cases. The overall findings indicated that PSK and/or OK with MMC and FT are effective in prolonging the lives of post-operative patients.
