[Curative Resection for Chemorefractory Advanced Gastric Cancer with Pancreatic Invasion by Pancreatoduodenectomy - A Case Report].

A 37-year-old woman was diagnosed with advanced gastric cancer. Pancreatic invasion of the tumor and positive cytology from peritoneal washing was found on staging laparoscopy. The patient received chemotherapy consisting of S-1 and CDDP, but the tumor size increased after 5 courses. The patient then received 2 courses of second line chemotherapy consisting of biweekly CPT-11; however, the tumor progressed and caused stenosis of the stomach. After gastrojejunostomy for the stenosis, negative cytology of intraperitoneal lavage was found. The patient underwent pancreatoduodenectomy with right hemicolectomy and wedge resection of the portal vein as curative resection. The patient was alive without recurrence 10 months after the surgery.
