[A case of advanced gastric cancer effectively treated on an outpatient basis by biweekly S-1 and docetaxel combination chemotherapy].

A 70-year-old male patient had advanced gastric cancer with severe lymph node metastasis. He was treated by combination chemotherapy of S-1 120 mg/body (1-week administration and 1-week rest)and docetaxel (DOC) 40 mg/body( day 1 and 15). After 2 courses of treatment, the primary lesion was remarkably improved and para-aortic lymph nodes disappeared by CT scan, so we diagnosed it as a partial response (PR). Anemia (WHO grade 3) was observed as toxicity and treated with transfusion. This regimen could be performed on an outpatient basis for over 2 years, and the response was maintained on CT and endoscopic examination after 20 courses of treatment. The biweekly docetaxel and S-1 combination chemotherapy was thought to be an effective method as chemotherapy for an outpatient with advanced gastric cancer.
