[S-1-based chemotherapy for recurrent gastric cancer with peritoneal dissemination resulting in long-term survival--report of a case].

Le résumé fourni par la source

A 52-year-old man underwent distal gastrectomy for gastric cancer in July 2000. In July 2005, abdominal CT and barium study of the colon revealed peritoneal recurrence, and chemotherapy of S-1 was started. Within 2 courses, the serum CEA level increased, so combination chemotherapy of S-1 and cisplatin (CDDP) was begun. After 7 courses, the regimen was switched to S-1+paclitaxel (PTX). However, the patient developed digital numbness within 8 courses and single-agent chemotherapy with S-1 was restarted. In July 2007, he developed abdominal distension, and abdominal CT showed a large amount of ascites. S-1+CDDP was administered again, however, and we had to change the regimen within 3 courses due to fatigue and appetite loss. S-1 was restarted, but soon severe fatigue and appetite loss restricted the use of chemotherapeutic agents, and he died in December. This patient had been alive for 2 years and 5 months since peritoneal recurrence was diagnosed. We concluded that S-1-based sequential chemotherapy was effective for recurrent gastric cancer.
