N2 - BACKGROUND: The risk for multicentricity of pancreatic adenocarcinoma remains unclear and the question whether pancreaticoduodenectomy represents sufficient oncological treatment for patients with ductal adenocarcinoma of the head of the pancreas needs further investigation.PATIENTS AND METHODS: Clinicopathological data of patients who underwent pancreaticoduodenectomy for pancreatic adenocarcinoma between 2005 and 2015 were assessed and the incidence of tumor multicentricity among patients who required salvage pancreatectomy within 90 postoperative days was evaluated.RESULTS: Pancreaticoduodenectomy was performed in 1,005 patients. Sixty-two patients (6%) suffered a major postoperative complication (pancreatic fistula/anastomotic leak/bleeding) after resection of the head of the pancreas, requiring salvage pancreatectomy. Histological examination of the pancreatic remnant in patients with ductal adenocarcinoma (n=19) revealed multicentric carcinoma in two patients, resulting in an incidence of 11% for tumor multicentricity. Preoperative cross-sectional imaging failed to identify tumor multicentricity in these patients. Additionally, two patients with pancreatic intraepithelial neoplasia and two with neuroendocrine tumor were identified.CONCLUSION: The incidence of previously undetected multicentric adenocarcinoma among patients undergoing salvage pancreatectomy in our study was surprisingly high. This finding suggests that the role of total pancreatectomy for pancreatic head cancer, as well as the current strategies for postoperative tumor surveillance, should be re-evaluated in order to provide the best oncological approach and prolonged survival for patients with ductal adenocarcinoma.
