Euthyroid Group

The purpose of this study is to determine \[for patients with previously treated well-differentiated thyroid cancer and evidence of residual disease based on serum thyroglobulin (Tg) level\] whether positron emission tomography-computed tomography (PET-CT) fusion scanning performed after recombinant thyroid-stimulating hormone (TSH) (rTSH, thyrotropin alfa for injection) will be more sensitive for the detection of disease sites than PET-CT scanning without rTSH. The study will also determine if this information will significantly alter the therapeutic approach in some patients.

PET/CT was performed before (basal PET) and 24 - 48 h after rhTSH administration (rhTSH-PET) in 63 patients (52 papillary and 11 follicular thyroid cancers). Images were blindly analyzed by two readers. The proposed treatment plan was prospectively assessed before basal PET, after basal PET, and again after rhTSH-PET.

Adults (age \>18 years) with a history of treated well-differentiated epithelial thyroid carcinoma (papillary, follicular, or Hürthle cell), for which total or near total thyroidectomy plus postoperative radioiodine remnant ablation with 131-I has either been performed or found to be unnecessary by radioiodine imaging after TSH stimulation.
