Primary Purpose: | Diagnostic |
Official Title: | Utility of Recombinant Human Thyrotropin (rTSH) PET-CT Fusion Scanning to Identify Residual Well-Differentiated Epithelial Thyroid Cancer |
Study Start Date : | March 2005 |
- PET-CT fusion scanning after rTSH will be more sensitive to detect disease sites than scanning without rTSH; this information will significantly alter the therapeutic approach in some patients.
- Increase in FDG PET SUV after rTSH will be more specific for metastases than for nonneoplastic processes (e.g., infection and muscle contraction).

Ages Eligible for Study: | 18 Years and older (Adult, Senior) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Adults (aged ≥ 18 years) with history of treated well-differentiated epithelial thyroid carcinoma (papillary, follicular or Hurthle 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.
- Serum thyroglobulin (Tg) concentration ≥ 10 ng/mL (in the absence of interfering Tg autoantibodies).
- No findings of a "qualifying" radioiodine whole body scan that are sufficient to localize the disease suspected on the basis of the serum Tg.
- Inconclusive disease localization despite clinical assessment, cervical sonography, CT or magnetic resonance (MR) of the chest, and when appropriate other imaging and biopsy procedures. Patients must have no more than three foci of known or suspected extra-cervical metastasis.
- Must be in stable medical condition.
- Must be able to fully understand the protocol and be compliant with instructions.
Exclusion Criteria:
- Diabetes mellitus, due to interference with fluorodeoxyglucose (FDG) PET scanning.
- Claustrophobia, inability to lay supine, or other factors preventing cooperation with scanning procedures.
- Withdrawal of thyroid hormone or rTSH administration within the preceding month.
- Presence of circulating Tg autoantibodies interfering with serum Tg measurement.
- Women who are pregnant or breastfeeding
