BACKGROUND
The management of multiple endocrine neoplasia, type 1 (MEN-1) pancreatoduodenal neuroendocrine neoplasms (NENs) is controversial. An aggressive surgical approach is intended to control the functional syndromes and malignant potential for nodal or distant metastasis.
METHODS
The results of treating 39 patients with MEN-1 pancreatoduodenal NENs over a 35-year period are available from chart reviews and patient interviews. This study focuses on pattern of disease, disease recurrence, and long-term functional outcomes.
RESULTS
Between 1967 and 2003, 39 patients ages 19 to 58 years (mean age, 37) had abdominal operations for their pancreatoduodenal NENs: 26 with Zollinger-Ellison syndrome, 4 with hypoglycemia, 3 with both Zollinger-Ellison syndrome and hypoglycemia, and 6 with nonfunctional neoplasms. Fifteen of these 39 patients had malignant disease on initial abdominal operation; 24 of 39 patients have not required abdominal reoperation, 17 of whom have available follow-up data. Of these 17 patients, 11 have biochemical evidence of disease recurrence (increased serum concentrations of gastrin, insulin, or pancreatic polypeptide), while 6 have no biochemical evidence of recurrence. A total of 30 abdominal reoperations were performed in 15 patients; 14 of 15 patients undergoing 1 or more reoperations developed evident malignant disease by their most recent operation. Nine of 13 reoperative patients with follow-up data have evidence of disease recurrence. Functional outcomes available in 20 patients showed that 10 patients require insulin and that 6 require oral hypoglycemic medications. Ninety percent have no abdominal pain or nausea/vomiting, while 4 are unable to return to work secondary to this disease.
CONCLUSIONS
Treatment of MEN-1 pancreatoduodenal NENs is met with frequent recurrence and some treatment-related morbidity and mortality. Most patients (22 of 39) eventually demonstrated malignant growth, but, with this strategy, few died of this disease.
