摘      要：BACKGROUND Pancreaticoduodenectomy(PD)for advanced gastric cancer is rarely performed because of the high morbidity and mortality rates and low survival ***,neoadjuvant chemotherapy for advanced gastric cancer has improved,and chemotherapy combined with trastuzumab may have a preoperative tumorreducing effect,especially for human epidermal growth factor receptor 2(HER2)-positive *** SUMMARY We report a case of successful radical resection with PD after neoadjuvant S-1 plus oxaliplatin(SOX)and trastuzumab in a patient(66-year-old male)with advanced gastric cancer invading the pancreatic *** esophagogastroduodenoscopy detected a type 3 advanced lesion located on the lower part of the stomach obstructing the pyloric *** tomography detected lymph node metastasis and tumor invasion to the pancreatic head without distant *** findings revealed adenocarcinoma and HER2 positivity(immunohistochemical score of 3+).We performed staging laparoscopy and confirmed no liver metastasis,no dissemination,negative lavage cytological findings,and immobility of the distal side of the stomach due to invasion to the *** gastrojejunostomy was performed at that *** course of SOX and three courses of SOX plus trastuzumab were *** computed tomography showed partial response;therefore,PD was performed after neoadjuvant chemotherapy,and pathological radical resection was *** We suggest that radical resection with PD after neoadjuvant chemotherapy plus trastuzumab is an option for locally advanced HER2-positive gastric cancer invading the pancreatic head in the absence of non-curative factors.
