[Three cases of recurrent gastric cancer responding to TS-1 therapy following combination therapy with 5-fluorouracil, mitomycin C and cisplatin].

We report three patients with recurrent gastric cancer responding to TS-1 therapy after combination chemotherapy with 5-fluorouracil, mitomycin C and cisplatin. All 3 cases had undergone total gastrectomy with lymphadenectomy for advanced gastric cancer. Postoperative follow-up computed tomography (CT) showed liver metastases (cases 1 and 3), peritoneal dissemination (case 2) and enlargement of paraaortic lymph nodes (case 1) due to cancer recurrence. After 2 to 4 courses of combined treatment with 5-fluorouracil (500-750 mg/body/day, days 1-5, civ), mitomycin C (6-8 mg/body, day 6) and cisplatin (60-80 mg/body, day 7), CT revealed considerable reduction of the metastatic tumors. Subsequently oral administration of TS-1 (80-100 mg/body/day) for 4 weeks was performed. All 3 patients are well without any signs of increase in tumor size.
