A Case of Locally Advanced Gastric Cancer after Neoadjuvant Chemotherapy

A 60s male was admitted to our hospital because of appetite loss and nausea. After examination, he was diagnosed with type 3 advanced gastric cancer in the antrum. Abdominal computed tomography showed gastric cancer invasion to the left liver lobe. We initiated neoadjuvant chemotherapy using S-1 plus CDDP after laparoscopic gastrojejunostomy. S-1 was orally administered for 3 weeks followed by a 2-week drug-free period. CDDP was administered intravenously on day 8 of each course. After 5 courses of chemotherapy, the gastric cancer was reduced in size. We therefore performed total gastrectomy with D2-affiliated left liver resection. S-1 plus CDDP is expected to improve outcomes in unresectable or locally advanced gastric cancer.
