title: [A case of advanced gastric cancer with peritoneal dissemination responding remarkably to TS-1/CDDP combination chemotherapy].
abstract: A 57-year-old woman visited a physician with complaints of anorexia and pollakiuria. Because a pelvic tumor and ascites were detected, she was referred to our department. Douglas pouch puncture revealed adenocarcinoma cells. Further examination showed an advanced gastric cancer with peritoneal dissemination. The cancer was judged to be unresectable. Chemotherapy with a combination of TS-1 and CDDP was performed before the operation. After 2 courses of the chemotherapy, her complaints disappeared, although abdominal CT confirmed remaining peritoneal dissemination. After 7 courses of chemotherapy, abdominal CT showed that the peritoneal dissemination had disappeared. Total gastrectomy and lymph node dissection were performed. Histological findings of the stomach revealed complete disappearance of cancer cells in the stomach and the regional lymph nodes. We confirmed that the TS-1/CDDP therapy resulted in a complete response to advanced gastric cancer and peritoneal dissemination. We recommend that chemotherapy be continued until the peritoneal dissemination disappears.
