Gastrinomas represent only a small fraction of pancreatic and duodenal tumors. They may occur sporadically (75%) or in association with genetic endocrine disorders such as MEN I (25%), also known as Wermer syndrome.¹ Differences in the pathogenesis of gastrinomas in these 2 subtypes have implications for presentation, treatment, and survival.

Patients with MEN I often present with ZES at a younger age, typically in the fourth decade of life.^1-2 The diagnosis is based on elevated gastrin levels in the presence of gastric hyperacidity. Secretin stimulation of gastrin levels may be required to diagnose ZES. The severity of symptoms and degree of gastrin level elevation does not differ by tumor location or by the subtype of disease.

In patients with ZES and proved or suspected MEN I, serum calcium and . . . [Full Text of this Article]
