Complete Response of Liver Metastasis of Gastric Cancer Treated by S-1 Chemoradiotherapy : A Case Report

الملخص EN

This paper presents a case of suspected liver metastasis of gastric cancer and a virtual complete response to S-1 chemoradiotherapy.

A 69-year-old man underwent distal gastrectomy for gastric cancer in 2008.

Multiple liver metastases occurred in 2009.

He underwent 15 courses of S-1 therapy and radiation therapy (37.5 Gy).

Abdominal computed tomography showed virtual complete disappearance of liver metastasis after chemoradiotherapy.

Hence, this case was interpreted as a complete response.

No sign of recurrence was noted 18 months after complete response was confirmed.

S-1 chemoradiotherapy is likely to be effective in treating patients with liver metastases of gastric cancer.
