Pancreatoduodenectomy in MEN1 patients can control hormone secretions (gastrin, glucagon, VIP) and remove large NETs. PD was found to control gastrin secretions in about 60% of cases.
Aim To assess postoperative complications and control of hormone secretions following pancreatoduodenectomy (PD) performed on multiple endocrine neoplasia type 1 (MEN1) patients with duodenopancreatic neuroendocrine tumors (DP-NETs). Background The use of PD to treat MEN1 remains controversial, and evaluating the right place of PD in MEN1 disease makes sense. Methods Thirty-one MEN1 patients from the Groupe d'etude des Tumeurs Endocrines MEN1 cohort who underwent PD for DP-NETs between 1971 and 2013 were included. Early and late postoperative complications, secretory control and overall survival were analyzed. Results Indication for surgery was: Zollinger-Ellison syndrome (n = 18; 58%), nonfunctioning tumor (n = 9; 29%), insulinoma (n = 2; 7%), VIPoma (n = 1; 3%) and glucagonoma (n = 1; 3%). Mean follow-up was 141 months (range 0-433). Pancreatic fistulas occurred in 5 patients (16.1%), distant metastases in 6 (mean onset of 43 months; range 13-110 months), postoperative diabetes mellitus in 7 (22%), and pancreatic exocrine insufficiency in 6 (19%). Five-year overall survival was 93.3% [CI 75.8-98.3] and ten-year overall survival was 89.1% [CI 69.6-96.4]. After a mean follow-up of 151 months (range 0-433), the biochemical cure rate for MEN-1 related gastrinomas was 61%. Conclusion In MEN1 patients, pancreatoduodenectomy can be used to control hormone secretions (gastrin, glucagon, VIP) and to remove large NETs. PD was found to control gastrin secretions in about 60% of cases.
