Long-term results of surgery for pancreatic neuroendocrine neoplasms in patients with MEN1.
Langenbecks Arch Surg. 2011 Dec; 396(8):1187-96.LA

Abstract

PURPOSE

This study was made to evaluate long-term results of an aggressive surgical approach for pancreaticoduodenal neuroendocrine neoplasms (pNENs) in patients with multiple endocrine neoplasia type 1 (MEN1).

METHODS

MEN1 patients with either biochemical evidence of functioning or non-functioning pNENs larger than 1 cm in size on imaging underwent duodenopancreatic surgery. Since 1997, patients were followed annually by biochemical testing and imaging studies.

RESULTS

Thirty-eight genetically confirmed MEN1 patients underwent duodenopancreatic resection for functioning (n = 22) or non-functioning (n = 16) pNENs, nine patients were yet not operated. Malignant disease occurred in 12 (35%) patients defined by either lymph node (12 patients) and/or distant metastases (2 patients). Six patients with Zollinger-Ellison syndrome (ZES) required pylorus-preserving pancreaticoduodenectomy (PPPD) as initial or redo procedure and 32 patients underwent other duodenopancreatic resections. Ten (26%) patients underwent up to four reoperations for either recurrent or metastatic disease that resulted in completion pancreatectomy in four patients. After median 109 months, 44 patients were alive and three patients died, one due to thymic carcinoid and two of unrelated causes. All eight patients with organic hyperinsulinism and 7 of 13 patients with ZES were biochemically cured. However, 24 of 38 (78%) patients developed new pNENs in the pancreatic remnant, but none developed distant metastases.

CONCLUSIONS

Early resection of pNENs in MEN1 may prevent the development of distant metastases. However, the majority of patients develop new pNENs in the duodenopancreatic remnant which may require completion pancreatectomy in the long term.
