Treatment:

Oncocytic adenomas are treated with a simple lobectomy or nodulectomy, which is curative but should not be enucleated, as an evaluation of their capsule is essential for the pathologist to determine whether the tumor is benign or malignant. Carcinomas are treated with total/subtotal thyroidectomy followed by radioactive iodine therapy. Oncocytic carcinomas tend to have lower iodide uptake compared with non-oncocytic cancers and are often therefore less responsive to radioactive iodide administration.

Prognosis:

The extent of tumor invasion determines the prognosis in oncocytic carcinomas. Patients with widely invasive tumors (defined as having 2 or more foci of capsular and/or vascular invasion) have a mortality of approximately 50% with median disease specific survival of 7 years. Patients with minimally invasive carcinoma have excellent prognosis with no tumor recurrences or disease related deaths reported in a recent series. Extrathyroidal extension and nodal metastases are adverse predictors of survival after multivariate analysis in widely invasive oncocytic carcinoma.
