We report a case of a 59-year-old man with advanced gastric cancer. Distal gastrectomy with lymph node dissection (D1) was performed. Pathological staging was IV (T3N1CY1), and the operation resulted in curability C. The serum CA19-9 level before the operation was 201 U/ml, and it did not normalize 3 months after the operation. Postoperative chemotherapy (TS-1, 100 mg/day) was performed. Because the tumor markers such as CEA and CA19-9 level elevated 5 months after the operation, triweekly docetaxel therapy and TS-1 administration (days 1-14) were performed. We disbontinued this therapy after 2 courses due to adverse reactions, such as leukopenia (grade 4) and liver dysfunction (grade 2). Peritoneal dissemination was diagnosed by the appearance of ascites and thickness of the peritoneum 11 months after the operation. So the patient was treated with a biweekly combination chemotherapy of irinotecan (CPT-11 60 mg/m2) and cisplatin (CDDP 30 mg/m2). Eight courses of this therapy induced partial remission and normalization of the serum CEA level. No major adverse reaction to this therapy was observed. The partial remission and good patient's QOL were achieved during follow-up 7 months after the administration of CPT-11 plus CDDP. This case suggests that patients with recurrent peritoneal dissemination of gastric cancer could benefit from CPT-11 with CDDP combination therapy as a second-line or third-line treatment.
