Predictive Value of Recombinant Human TSH Stimulation and Neck Ultrasonography in Differentiated Thyroid Cancer Patients

Abstract

A second rhTSH stimulation is useless in DTC patients who were rhTSH-Tg and imaging negative at first follow-up, while it is suggested in patients with detectable, although low, rhTSH-Tg levels at first follow-up: in the absence of clinical or US evidence of disease persistence, these patients should not be retreated by radioiodine, but simply scheduled for a later rhTSH stimulation.
