Treatment of Multiple Endocrine Neoplasia Type 2A in Liver Metastases of Medullary Thyroid Carcinoma

In patients with Multiple endocrine neoplasia type 2A (MEN2A), medullary thyroid carcinoma (MTC) can spread to the liver. Hepatic metastases represent an important clinical challenge in advanced disease, and the management approach is guided by the extent and distribution of liver involvement.

Clinical scenario: MEN2A complicated by liver metastases of medullary thyroid carcinoma. Liver metastases occur in 45% of patients with advanced MTC, making hepatic disease management a key consideration in this population.

Treatment approach

Management of hepatic metastases in this setting involves hepatic-directed interventions. The choice between approaches depends on the characteristics of the liver involvement — the complete protocol specifies the criteria used to guide that decision.

Surgical resection should be considered in patients with large isolated hepatic metastases.

Chemoembolization should be considered in patients with disseminated tumors less than 30 mm in size involving less than a third of the liver.
