Gastric carcinoid tumors in multiple endocrine neoplasia-1 patients with Zollinger-Ellison syndrome can be symptomatic, demonstrate aggressive growth, and require surgical treatment.Norton JA, Melcher ML, Gibril F, Jensen RT Department of Surgery, Stanford University Medical Center, 300 Pasteur Drive, Stanford, CA 94305-5651, USA. BACKGROUND: Gastric carcinoid tumors occur in 15% to 50% of patients with multiple endocrine neoplasia-1/Zollinger-Ellison syndrome (MEN-1/ZES) but are thought to be benign. We report 5 patients with MEN-1/ZES with symptomatic, aggressive gastric carcinoid tumors that required surgical procedures. METHODS: This was a retrospective chart review. RESULTS: Each patient had MEN-1/ZES. Each patient had innumerable gastric carcinoid tumors with symptoms. The fasting gastrin level was 47,000 pg/mL (normal, <200 pg/mL); the basal acid output was 79 mEq/hr (n = 3), and the age at surgical exploration was 47 +/- 6 years, with a duration of MEN-1 of 21 +/- 3 years and of ZES of 15 +/- 2 years. All patients had elevated 5-HIAA or serotonin levels. Somatostatin receptor scintigraphy showed increased stomach uptake in 4 patients (80%). Four patients had a total gastrectomy; 4 patients had lymph node metastases removed, and 3 patients had liver metastases resected. One patient who did not have a total gastrectomy had liver carcinoid metastases. CONCLUSIONS: These results demonstrate that gastric carcinoid tumors in patients with longstanding MEN-1/ZES may be symptomatic, aggressive, and metastasize to the liver. With increased long-term medical treatment and life expectancy, these tumors will become an important determinant of survival. Published 19 January 2005 in Surgery, 136(6): 1267-74.
