Dynamic risk assessment in patients with differentiated thyroid cancer

摘要

The stratification of patients with differentiated thyroid cancer based on their initial risk of recurrence, according to specific clinical, histopathological and perioperative data, is an important starting point for tailoring the follow-up during the first 1–2 years after initial therapy (surgery with or without radioiodine ablation). However, risk of recurrence re-stratification based on new clinical data that becomes available after considering the response to treatment (dynamic risk assessment) provides a more accurate prediction of the status at final follow-up and a more individualized approach. In this review, we summarized the available data regarding dynamic risk of recurrence and the suggested management of differentiated thyroid cancer patients according to the response to treatment. The use of this strategy is crucial to avoid overtreatment and intensive follow-up of the vast majority of patients who will have a very good prognosis and, on the other hand, focus therapeutic efforts on those patients who will have a worse prognosis. In the future, molecular biology analysis of the tumors and well-designed prospective studies will probably refine the risk of recurrence prediction.
