Management of the central compartment in differentiated thyroid carcinoma

Abstract

Management of differentiated thyroid carcinoma (DTC) is gradually evolving with considerations of de-escalation of treatment and/or active surveillance in a significant proportion of patients on the basis of an improved understanding of the long-term disease and functional outcomes from both surgical and non-surgical approaches. This is fueled by improved risk stratification using clinicopathologic prognostic factors as determined through high resolution ultrasound and fine needle aspiration cytology. This paper discusses general recommendations for preoperative decision-making in the management of the central compartment in DTC with particular reference to micropapillary thyroid carcinoma and encapsulated follicular variant papillary thyroid carcinoma. Given the multitude of specific factors that must be considered for each patient, therapeutic decisions should occur in a multidisciplinary setting weighing the risks of treatment morbidity against the risks of disease progression or recurrence. Recurrent/persistent disease merits special attention with regard to pre-operative planning and surgical risk, and should be managed by high-volume thyroid surgeons.
