[A case of metastatic gastric cancer responding to weekly administration of paclitaxel as a second-line therapy].

We report a 65-year-old man who underwent distal gastrectomy for advanced and metastatic gastric cancer in June 2000. TS-1 was administered for remnant metastatic lesions as first-line chemotherapy, but a recurrence was found in June 2001. Paclitaxel 80 mg/m2 was then administered weekly in a 1-h infusion on day 1, 8, and 15 as one cycle. After two cycles of paclitaxel administration, the patient was relieved from abdominal pain, and a barium enema revealed marked improvement of the colonic stenosis due to the peritoneal metastasis. There have been few effective chemotherapeutic agents against peritoneal metastasis from gastric cancer to date; however, a weekly paclitaxel regimen is considered to be one of the promising regimens for metastatic and recurrent gastric cancer.
