Differentiated thyroid cancer: Clinicopathologic staging

R Michael Tuttle, MD

Clinicopathologic staging of patients with cancer is valuable for many reasons, including the following:

To estimate risk of recurrence and disease-specific mortality for an individual patient

To tailor decisions regarding postoperative adjunctive therapy (such as the need for radioiodine [RAI] ablation and degree of thyroid-stimulating hormone [TSH] suppression) to the patient's risk for disease recurrence and mortality

To make decisions regarding the frequency, modality, and intensity of follow-up based upon an individual patient's risk of recurrence and mortality

To enable accurate communication regarding a patient among health care professionals
