[A case of gastric cancer with peritoneal dissemination responding to combination chemotherapy with oral fluoropyrimidine and weekly paclitaxel].

We report a case in which combination chemotherapy with oral fluoropyrimidine and weekly paclitaxel was effective for gastric cancer with peritoneal dissemination. A 44-year-old woman suffering from advanced gastric cancer with peritoneal dissemination underwent total gastrectomy. After surgery, combination chemotherapy with doxifluridine plus weekly paclitaxel was administered on an outpatient basis, and was effective without any sign of relapse of the disease for a year. However, she complained of dull abdominal pain, and ascites was observed 13 months after surgery. She received combination chemotherapy with S-1 plus weekly paclitaxel. The ascites decreased after 3 courses of the chemotherapy. No major adverse effect was observed except for grade 1 anemia and grade 2 hair loss. She has been well with the chemotherapy on an outpatient basis 18 months after surgery.
