[A case of recurrent advanced gastric cancer with lung metastasis effectively treated by combined chemotherapy of TS-1 and weekly CDDP].

We report a case of a patient with recurrent gastric cancer and lung metastasis, who responded remarkably to combination chemotherapy using TS-1 and weekly CDDP. The patient was administered 2 courses of TS-1 (80 mg/m2/day, on day 1-21) and CDDP (25 mg/m2/day, on day 8, 15, 22) every 5 weeks. The regimen was done on an outpatient basis. The treatment resulted in the metastatic tumors in the lung disappearing after 1 course. No severe side effects were observed. This combination therapy proved useful for treating lung metastasis from gastric cancer in this patient.
