Well Differentiated Thyroid Carcinoma: Current Treatment

Well differentiated thyroid carcinoma (WDTC) is a relatively common malignancy accounting for an estimated 37,000 thousand cases in the United States in 2009 [1]. WDTC also has a generally high 5 year survival rate that correlates with age. Papillary thyroid carcinoma (PTC) greater than 1 cm is best managed by total thyroidectomy. Thyroid lobectomy and isthmusectomy may be adequate for unifocal PTC less than 1 cm in patients without negative prognostic factors. Central compartment and possible lateral neck dissections should be performed when nodal metastases are present in the respective nodal basins. Post-operatively, radioactive iodine ablation with 131I followed by thyroid stimulating hormone (TSH) suppression is indicated in certain patients to improve locoregional control and reduce recurrence.
