Abstract

We report 2 cases of curative resection of pancreatic cancer after neoadjuvant chemotherapy. A 60-year-old woman was diagnosed as having borderline resectable pancreatic ductal adenocarcinoma with invasion of the nerve plexus covering the superior mesenteric artery. The preoperative chemotherapy, 4 courses of gemcitabine and S-1, reduced the volume of tumor; pancreaticoduodenectomy with portal vein resection after chemotherapy resulted in R0 resection. Pathological examination of the resected specimen showed fibroid tissue with myxoid degeneration and mucinous lake surrounded by differentiated adenocarcinoma. A 40-year-old woman was diagnosed as having borderline resectable pancreatic ductal adenocarcinoma with invasion of the common hepatic artery and splenic artery. The preoperative chemotherapy, 4 courses of gemcitabine and S-1, reduced the tumor volume; distal pancreatectomy with portal vein resection after chemotherapy obtained R0 resection. Pathological examination of the resected specimen revealed that the majority of the tumor was fibrotic and necrotic tissue, and few cancer cells remained viable. Neoadjuvant chemotherapy has a potential to increase the rate of R0 resection. Furthermore, preoperative chemotherapy can he...Continue Reading
