Key Points about Multiple Endocrine Neoplasia:
- Definition: Multiple Endocrine Neoplasia (MEN) is a group of rare, inherited disorders characterized by the development of tumors in multiple endocrine glands. MEN is classified into types 1, 2A, and 2B, each with specific gland involvement, such as the parathyroid, pituitary, thyroid, and adrenal glands.
- Causes: MEN is caused by genetic mutations, specifically in the MEN1 gene for MEN type 1 and RET proto-oncogene mutations for MEN types 2A and 2B. These mutations lead to abnormal growth of endocrine tissues, predisposing individuals to tumors.
- Symptoms: Symptoms vary depending on the type of MEN and affected glands. Common presentations include hypercalcemia (MEN1), medullary thyroid cancer (MEN2A and 2B), pheochromocytoma, hyperparathyroidism, and gastrointestinal symptoms from pancreatic tumors. Mucosal neuromas and marfanoid habitus are specific to MEN2B.
- Investigations: Diagnosis is based on clinical features, family history, genetic testing for MEN1 and RET mutations, and biochemical tests such as calcium levels, parathyroid hormone, catecholamines, and calcitonin levels. Imaging studies, including MRI, CT, or ultrasound, are used to localize tumors.
- Management: Management involves surgical resection of tumors, regular monitoring of endocrine function, genetic counseling, and screening for at-risk family members. Specific management depends on the type of MEN and affected glands. Medullary thyroid cancer requires early thyroidectomy in MEN2.
- Complications: Complications include hormone overproduction, malignancy risk, and recurrence of tumors. Early detection and proactive management can help reduce morbidity and improve prognosis.
