A 50-year-old man had undergone total gastrectomy and splenectomy for advanced gastric cancer in October 2000, and was then treated with postoperative adjuvant chemotherapy for 2 years. In June 2005, we made a diagnosis of recurrent gastric cancer with peritoneal dissemination. Although the chemotherapy with TS-1/CPT-11 was started, it was discontinued after 2 courses because of subileus. Despite a change to second-line chemotherapy with CPT-11/CDDP, progressive disease due to a large amount of ascites was confirmed after 3 courses. Therefore, chemotherapy with doxifluridine (5'-DFUR)/paclitaxel (PTX) was selected as third-line treatment. After completion of 3 courses, abdominal computed tomography revealed a marked decrease of ascites. After 8 courses we discontinued 5'-DFUR/PTX chemotherapy, so the increase of ascites was remarkable. All response time was 197 days. The patient had good quality of life. 5'-DFUR/PTX combination chemotherapy can be expected to improve patient quality of life and show good therapeutic efficacy against recurrent gastric cancer with peritoneal dissemination.
