[A case of TS-1 resistant recurrent gastric cancer with lung metastasis responding to TS-1 and irinotecan combination therapy].
We report a case of TS-1-resistant recurrent gastric cancer with lung metastasis responding to TS-1 and irinotecan (CPT-11) combination therapy. A 72-year-old man underwent total gastrectomy with pancreaticosplenectomy for advanced gastric cancer on October 18, 2001, and partial hepatectomy for postoperative liver metastasis on August 22, 2002. In March 2004, a chest computed tomography scan revealed metastatic lesions in the bilateral lungs, and he received a single administration of TS-1, resulting in partial response. After 13 courses, this therapy was discontinued due to progressive disease. Then,TS-1 and CPT-11 combination therapy was chosen as the second-line chemotherapy. After 4 courses, a partial response was obtained in lung metastasis, and thereafter has been maintained. He has been treated on an outpatient basis because of no grade 3 or severer adverse reactions. TS-1 and CPT-11 combination therapy could be a promising regimen as the second-line chemotherapy for gastric cancer resistant to TS-1.
