BackgroundIslet cell tumor (ICT) metastasis is one of the potentially lethal outcomes of multiple endocrine neoplasia type 1 (MEN 1). Management of ICT in patients with MEN 1 is controversial; some advocate resection based on biochemical evidence of progression, whereas others use tumor size to predict the risk of metastasis and the need for resection. This study correlates the size of primary ICT with the presence of metastases.MethodsForty-eight patients with MEN 1 with ICT, from 34 kindreds followed up in our multiple endocrine neoplasia program, were evaluated; 43 of the 48 have been explored for ICT. Metastases to the lymph nodes and liver were documented.ResultsThirty-three percent of patients with pancreatic tumors less than 1 cm in greatest diameter had metastatic disease at surgery and in follow-up, whereas 34.8% of patients with tumors greater than 2 cm in diameter had metastases to lymph nodes or liver. The 2 patients with liver metastases each had primary tumors greater than 2 cm. Follow-up revealed subsequent metastasis in 1 patient.ConclusionsThe size of primary tumors in MEN 1 does not correlate with metastatic potential. This is not a good criterion for exploration. Continued follow-up of these patients will be necessary to define the effect of operation on the course of ICT in MEN 1. (Surgery 1999;125:1043-9.)
