Abstract
Background: To prevent the unwarranted effects of post-thyroidectomy hypothyroidism prior to radiodine (RAI) ablation, patients with well-differentiated thyroid cancer can currently undergo this treatment while in a euthyroid state. This is achieved with the use of recombinant human thyroid-stimulating hormone (rhTSH) injections prior to the ablation.
Objectives: To demonstrate the efficacy of rhTSH in radioiodine thyroid ablation in patients with differentiated thyroid cancer.
Methods: We conducted a retrospective study of patients who underwent total thyroidectomy for well-differentiated thyroid cancer with different levels of risk, treated with rhTSH prior to remnant ablation with radioiodine.
Results: Seventeen patients with thyroid cancer were studied and followed for a median of 25 months (range 8–49 months). Ablation (defined as stimulated thyroglobulin < 1 mg/ml, negative neck ultrasonography, and radioiodine scan) was successful in 15 patients (88.2%). One of the patients was lost to follow-up.
Conclusions: The use of rhTSH with postoperative radioiodine ablation may be an efficient tool for sufficient thyroid remnant ablation, avoiding hypothyroidal state in the management of thyroid cancer patients.
