[A case of non-curatively resected gastric cancer successfully treated over 17 months with TS-1 and irinotecan combination therapy].

We report a case of non-curatively resected gastric cancer successfully treated with TS-1 and irinotecan (CPT-11) combination therapy, resulting in long-term survival of 17 months. A 56-year-old woman underwent noncurative resection with total gastrectomy for advanced gastric cancer with severe lymph node metastasis on June 3, 2004. Postoperatively, She received TS-1 and CPT-11 combination therapy (TS-1 80 mg/m(2) day 1-21, CPT-11 80 mg/m(2) day 1, 15, every 5 weeks). However, due to grade 4 neutropenia, and grade 3 nausea and anorexia in the first course, both doses were reduced. Since then, no grade 3 or severer adverse reactions have been observed. After 5 courses, partial response to lymph node metastasis was obtained, and her quality of life was improved. Thus, TS-1 and CPT-11 combination therapy has been effective for 17 months, suggesting that it is promising for long-term administration and survival to continue it perseveringly.
