Abstract
Levotriiodothyronine (LT3)-assisted withdrawal may improve short-term tolerability during hypothyroidism induction in patients with differentiated thyroid carcinoma undergoing preparation for radioactive iodine therapy. Recent findings suggest a more favorable laboratory profile while maintaining adequate thyroid-stimulating hormone stimulation. However, adequate TSH elevation remains a surrogate marker and does not directly establish therapeutic effectiveness. Future comparative studies should therefore determine whether the biochemical advantages of LT3-assisted withdrawal are accompanied by preserved radioactive iodine–related outcomes. Relevant endpoints may include post-therapy imaging findings, longitudinal thyroglobulin and anti-thyroglobulin antibody measurements, structural and biochemical response categories, and predefined ablation or follow-up outcomes. Integrating laboratory tolerability with clinically meaningful radioactive iodine endpoints would clarify whether LT3-assisted withdrawal represents not only a more tolerable but also an oncologically sound preparation strategy for patients with differentiated thyroid carcinoma.
