Trastuzumab, a humanized monoclonal antibody directed against human epidermal growth factor receptor２ （HER２）, has been shown to be active against metastatic gastric cancer that overexpress HER２. A ７８-year-old man presented with an edema in the lower legs. He was diagnosed as having advanced gastric cancers with multiple liver metastases in our hospital. Immunohistochemistry of the tumor cells revealed HER２ overexpression with an intensity of ３＋. The patient was treated with DS-T chemotherapy （Docetaxel＋S‐１＋Trastuzumab） because of the presence of renal dysfunction. Due to the adverse effect appeared with his skin, DS-T chemotherapy has been canceled and trastuzumab chemotherapy was continued. After １１ months of trastuzumab monotherapy, metastatic liver tumors were diminished. There is very few report of a positive response to trastuzumab in a patient with HER２‐overexpressing metastatic gastric cancer
