Because of its relative rarity and favorable outcome, it has not been feasible to assess medical interventions for thyroid cancer using randomized prospective trials. The approach to diagnosis and treatment relies to a great extent on information derived from retrospective studies. Overall prognosis and survival rates have been edging upward over the past two decades. This is attributed to a wider acceptance of total thyroidectomy as the primary surgical strategy. The appropriate indication of radioiodine therapy remains controversial, and physicians must be familiar with staging criteria to...
