[A case report of curative resection for gastric cancer with peritoneal dissemination successfully treated by combined chemotherapy of S-1 and paclitaxel].

The patient was a 54-year-old female with gastric cancer. As laparotomy showed diffuse peritoneal dissemination, only laparotomy was performed and chemotherapy was conducted with a combination of S-1 80 mg/m(2) (2 weeks administration and 1 week rest) and paclitaxel (PTX) 50 mg/m(2) (day 1, 8). After 5 courses of this regimen, endoscopy showed the tumor was reduced in size and PET-CT revealed no evidence of metastasis. She underwent total gastrectomy with D2 lymph node dissection and Roux-en Y reconstruction. Peritoneal metastasis histologically disappeared, and the final findings were T1, N0, H0, P0, CY0, M0, Stage I A, Cur A. The only adverse effect was grade 1 stomatitis during this chemotherapy. CT showed no findings of recurrence 11 months after the operation. The S-1/PTX combination chemotherapy was thought to be effective for gastric cancer with peritoneal dissemination and made curative operation possible in this case.
