A 46-year-old female was admitted to Kagoshima University Hospital with a complaint of epigastralgia and dysphasia. Gastrointestinal scopy revealed advanced gastric cancer in the upper third of the stomach. Pathological diagnosis of the biopsy specimen was moderately-differentiated adenocarcinoma. Abdominal CT suggested multiple liver metastases, so a combination of biweekly paclitaxel(PTX)and S-1 was started. After five courses of this regimen, the liver metastases and primary tumor were remarkably regressed. PTX was discontinued because of a grade 3 adverse effect of numbness. Nevertheless S-1 monotherapy for liver metastases resulted in a complete response. She has been well without tumor re-growth for 4 years. The combination of PTX and S-1 may be an effective regimen for gastric cancer with liver metastases.
