[A case of TS-1 resistant recurrent gastric cancer responding to TS-1 +CPT-11 combination therapy].
A 71-year-old man underwent distal partial gastrectomy for gastric cancer. Four years after surgery, the tumor marker was elevated. Examinations by computed tomography (CT) revealed para-aortic lymphnode swelling and hydronephrosis. The patient treated oral administration of TS-1 (120 mg/day). After 3 courses of treatment of TS-1, progressive disease was observed. TS-1+CPT-11 (TS-1 120 mg/day day 1-14, CPT-11 100 mg/day day 1, 15) combination therapy was then chosen as second-line chemotherapy. After 5 courses of combination therapy, the tumor marker was decreased and para-aortic lymphnodes could not be detected by CT. Only grade 2 leukopenia was observed as an adverse event during the therapy. TS-1+CPT-11 combination therapy could be useful as the second-line chemotherapy for cases of TS-1 resistant recurrent gastric cancer.
