Thyroid Fine Needle Biopsy, Radioiodine, and Dosimetry


National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)

Inclusion Criteria

Adults and children with known or suspected thyroid neoplasm will be considered for
participation. Enrollment will be capped accordingly:

1. Patients with thyroid nodules requiring evaluation and possible biopsy (no more than
30 per year);

2. Patients with recent diagnosis of thyroid cancer requiring consultation and
counseling about therapeutic options (no more than 10 per year);

3. Patients with established thyroid cancer requiring specialized studies such as (131)I
dosimetry (no more than 5 per year);

4. Enrollment of high risk, non-iodine avid, inoperable thyroid cancer only for purposes
of screening for eligibility for other specific thyroid cancer protocols.

Exclusion Criteria

1. Serious underlying medical conditions that restrict diagnostic testing or therapy
such as renal failure, congestive cardiac failure or active coexisting non-thyroid

2. Patients unable or unwilling to give informed consent

Detailed Description

Participants in this study will be patients diagnosed with or suspected to have a thyroid nodule or thyroid cancer. The main purpose of this study is to further understand the methods for the diagnosis and treatment of thyroid nodules and thyroid cancer. Many of the test performed are in the context of standard medical care that is offered to all patients with thyroid nodules or thyroid cancer. Other tests are performed for research purposes. In addition, blood and tissue samples will be taken for research and genetic studies.
