[A case of gastric carcinoma with peritoneal metastasis successfully treated by combination chemotherapy of S-1 and cisplatin].

Le résumé fourni par la source

This case is a 69-year-old woman. We diagnosed gastric cancer and cholecystolithiasis by close inspection of abdominal pain. Because preoperative diagnosis was T2N0M0, Stage I B, we performed an operation. Many lesser tubercles were shown, and were diagnosed as peritoneal metastases pathologically. The tumor in corpus ventriculi infiltrated out of gastric serosa. We judged that curative resection was impossible and finished the operation after giving an intra-abdominal dosage of cisplatin(CDDP)at 85mg. After operation, 3 courses of performed S-1/CDDP combination chemotherapy were performed. Because we observed contraction of the main lesion and could not point out the peritoneal metastases and ascitis, we performed a second look operation. All the nodules found with peritoneal and rectouterine excavation had disappeared and we performed distal gastrectomy. The postoperative diagnosis was pT2(MP), pN0CY0, Stage I B, Cur A, therapy grade 1a. Chemotherapy does succeed, and this is a valuable case in which a radical operation could be performed.
