The surgical approaches to MEN1 - what the endocrinologist needs to know

Controversy exists in the surgical treatment of patients with MEN 1 in relation to the timing and extent of interventions. Hyperparathyroidism in MEN 1 is caused by multiglandular disease and associated with high risk of supernumary glands. The findings on preoperative ultrasound and MIBI scans should not deter the surgeon from removing at least 3 parathyroid glands and the cervical thymus (1). Even subtotal parathyroidectomy (3½ glands) is associated with time dependant recurrence but lower risk of hypocalcaemia than total parathyroidectomy. The indications for surgical treatment of duodeno-pancreatic disease reflect the malignant potential of even small (<3 cm) pancreatic NET and syndromes of hormonal excess. High (>85%) biochemical cure rates can be achieved in gastrinoma patients, selective enucleation of pancreatic NETs is not indicated. Adrenal tumours > 10 mm in diameter, usually non-functioning, occur in at least 10% of individuals, MEN 1 is associated with an increased risk of adrenocortical cancer (2). MEN 1 related death occurs in approximately 70% of cases, increased risk is associated with thymic and duodenopancreatic tumours (3). In MEN 1 the heterogeneity of tumour penetrance and the risk of malignant transformation mandates lifelong follow up of gene carriers by an experienced multidisciplinary team. 1.
