Abstract: In Brief Objective: To analyze the penetrance and clinical course of isolated nonfunctioning tumors of the pancreas (NFTP) in MEN 1 patients, and to propose a strategy for managing them. Summary Background Data: Pancreaticoduodenal tumors develop in a majority of MEN 1 patients and are a major cause of death. The natural history of NFTP is poorly defined, and no clear-cut guidelines have been widely accepted regarding treatment. Methods: Data on 108 patients with isolated NFTP among 579 MEN 1 patients from the French Endocrine Tumor Study Group (GTE) were analyzed. Survival rates were calculated using the Kaplan-Meier method. Results: The penetrance of NFTP was 34% at age 50, making it the most frequent pancreaticoduodenal tumor in MEN 1 patients. Forty-three patients (40%) underwent surgery, 32 of them curatively. No patient died because of surgery. Average life expectancy for patients with NFTP was shorter than that for MEN 1 patients who did not have pancreaticoduodenal tumors. Thirteen patients died during follow-up, 10 due to NFTP. Tumor size was correlated with the risks of metastasis and death. These risks were low for patients with tumors ≤20 mm. Conclusions: NFTP are currently the most common tumors of the pancreaticoduodenal region in patients with MEN 1. Prevention of tumor spread by surgery should be balanced with potential operative mortality and morbidity. We do not recommend routine surgery for NFTP ≤20 mm. Nonfunctioning tumors of the pancreas (NFTP) are currently the most frequent pancreaticoduodenal tumors in MEN 1 patients. Among the 108 patients with NFTP in this study, 10 patients died from NFTP. A significant correlation between tumor size, metastasis, and reduced survival was demonstrated.
