[A case of curative surgery for HER2-positive gastric cancer after chemotherapy using paclitaxel combined with trastuzumab].

: A 74-year-old man was diagnosed with unresectable HER2-positive gastric cancer due to metastases to distant lymph nodes. Paclitaxel combined with trastuzumab was administered as third-line chemotherapy. After 4 courses of therapy, the metastases to distant lymph nodes disappeared with no evidence of progressive disease. Downstaging by chemotherapy made curative treatment feasible and he underwent distal gastrectomy. The patient has been free from recurrent disease 13 months after surgery.
