A 78-year-old female underwent a curative total gastrectomy with D2 lymphandectomy for advanced gastric cancer in March 2003. S-1 mono-therapy (80 mg/m2, day 1-28/42 days) began as the first-line chemotherapy from October 2004 when multiple lung metastases were detected by CT. Paclitaxel mono-therapy (80 mg/m2, days 1, 8, 15/28 days) began as the second-line chemotherapy from April 2005 when prior S-1 mono-therapy judged as progressive disease (PD) by CT. Paclitaxel mono-therapy judged it as partial response (PR) in June, but the final judgement was as PD in September 2005. S-1 + CPT-11 combination therapy (S-1: 80 mg/m2, day 1-21, CPT-11: 80 mg/m2, days 1, 15/35 days) began as the third-line chemotherapy from September 2005. After 10 courses, multiple lung metastases were judged as complete response (CR) in September 2006. During the third-line chemotherapy, any adverse event of grade 2 or more did not occur. After judgment of CR, the patient has been followed without chemotherapy due to patient's desire, and is still alive without any recurrence in July 2007.
