[A case of long-term survival of gastric cancer with peritoneal metastasis effectively treated by TS-1 and paclitaxel (PTX) combination therapy].

We experienced the case of a 62-year-old woman who obtained long-term survival of three years by TS-1+paclitaxel (PTX) administration for gastric cancer postoperative peritoneal metastases. We first performed total gastrectomy, and the diagnosis was T3N2M0, Stage IIIB. Next, we performed chemotherapy by postoperative 5-FU+cisplatin (CDDP) and met in ambulatory. A bowel movement aberration was found during the course at 3 years postoperatively, and close inspection revealed sigmoid colon stenosis by peritoneal metastases. After construction of an artificial anus, we started administration of TS-1+paclitaxel. Chemotherapy was continued on an outpatient basis, and at-home treatment was possible for about 26 months till symptoms aggravated. No grave adverse event occurred except for depilation of grade 1. It was thought that this long-term treatment on an outpatient basis contributed to survival.
