Improvement of Goiter Volume Reduction after 0.3 mg Recombinant Human Thyrotropin-Stimulated Radioiodine Therapy in Patients with a Very Large Goiter: A Double-Blinded, Randomized Trial

Abstract

rhTSH-stimulated (131)I therapy improves the reduction of very large goiters by more than 50%, compared with (131)I therapy alone, but at the expense of more adverse effects after therapy. Our data suggest that rhTSH stimulation may work through mechanisms that go beyond the increase in thyroid (131)I uptake.
