Quality of Life and Effectiveness Comparisons of Thyroxine Withdrawal, Triiodothyronine Withdrawal, and Recombinant Thyroid-Stimulating Hormone Administration for Low-Dose Radioiodine Remnant Ablation of Differentiated Thyroid Carcinoma

Abstract

Our study indicates that use of rhTSH preserves QoL in patients undergoing RI ablation and affords an ablation success rate comparable to that seen after thyroid hormone withdrawal. Notably, ablation preparation using withdrawal of LT3 for 2 weeks did not prevent development of profound hypothyroidism, as also occurred when LT4 alone was withdrawn for 4 weeks.
