Not Applicable
Conditions
Thyroid Carcinoma
Metastatic Sites Lung Bone Nodal
Registration Number
NCT00749697
Lead Sponsor
Royal Marsden NHS Foundation Trust
Brief Summary

The main purpose of the study is to establish a relationship between the administered activity of the radioiodine and absorbed dose in the tumor sites.

Detailed Description

Study Design - the assessment of patients with multiple tumour sites with metastatic thyroid cancer to correlate the administered activity to absorbed dose. Patients will receive the standard therapy dose of 5.5 GBq as per the hospital policy and there will be no change for the protocol purpose.
