[Postoperative immunochemotherapy for gastric carcinoma with peritoneal dissemination--the effects with the combination of CDDP, 5-FU and lentinan].

Three cases of postoperative gastric cancer with peritoneal dissemination were treated by combined administration of CDDP, 5-FU and Lentinan. CDDP was given intravenously at 20 mg/body on days one to five. At the same time, 5-FU was infused continuously 250-500 mg/body per day for more than two weeks, and Lentinan was given at a dose of 2 mg per week. Two courses were repeated every 3 weeks. This combination treatment was very effective because the median survival rate for the three patients was 13 months with no sign of recurrence, and the quality of life has been good.
