Controversies in the follow-up and management of well-differentiated thyroid cancer.

ABSTRACT

Thyroid cancer is a common malignancy with an apparent increasing incidence and a wide spectrum of clinical behavior and therapeutic responsiveness. Recent advances in diagnosis, primary treatment, and long-term monitoring have led to enhanced detection of primary and recurrent disease and improvements in therapy. Controversy still surrounds several issues the most accurate predictive staging system and histological subclassification scheme, optimal preoperative assessment and surgical extent, appropriate use of radioiodine for remnant ablation, goal for thyrotropin-suppressive thyroid hormone therapy, best practices in immediate postoperative and long-term monitoring, and approach to the patient with thyroglobulin evidence of residual disease. In this paper, recent data related to these controversial issues are critically reviewed.
