Prognosis of gastrinoma patients with metastases to lymph nodes only is uncertain, and the true nature of isolated nodal gastrinomas remains controversial. The purpose of this study was to determine the outcome of such patients and whether nodal gastrinomas may occur as primary lesions. Eleven patients with nodal involvement but without hepatic metastases are reported (mean follow-up of 129 months). Primary gastrinomas were located in the duodenum in seven (Group 1) and not identified in four (Group 2). In Group 1, five patients remained eugastrinemic after excision of all gross tumors and gastrectomy (n = 4) or pancreaticoduodenectomy (n = 1), one patient had residual disease and died of other causes (survival of 88 months), and one patient had MEA-I syndrome with multiple gastrinomas (follow-up of 126 months). In Group 2, three patients became eugastrinemic after nodal excision and total gastrectomy (mean follow-up of 212 months) and may represent primary nodal gastrinomas, and in one patient, liver metastases developed and the patient died. Four deaths occurred in a 27-year period, but only one was tumor-related. There was no significant difference in 20-year survival rates between the two groups (85% vs. 75%). It is concluded that 1) lymph node gastrinomas are usually metastatic from primary duodenal lesions, 2) although rare, nodal gastrinomas may occur as primary lesions, and 3) in the absence of hepatic metastases, lymph node gastrinomas, whether primary or metastatic, have a good prognosis and should not deter aggressive surgical treatment.
