Special Instructions

Only a limited number of patients are being recruited at the present time. Our major research focus is the diagnosis and treatment of clinically aggressive thyroid cancer. Current research aims are focusing on patients requiring dosimetry measurements, patients with iodine non-avid disease, as well as patients with progressive disease despite optimal prior surgical and radioiodine therapies.

If interested, have your health care provider send a written referral letter summarizing your thyroid disorder plus all applicable laboratory, radiology, and nuclear medicine reports. All biopsy or surgery pathology reports AND relevant slides must be included. This information will be reviewed by Principal Investigator to determine whether you are eligible for protocol enrollment.

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.

In order to be eligible to participate in this study, an individual must meet all of the following criteria:

1. Male or female, adults or children >= 6 months+.

2. Patients with known or suspected thyroid nodules and/or thyroid cancer.

3. At risk family members of patients who have a genetic susceptibility to developing thyroid cancer.


An individual who meets any of the following criteria will be excluded from participation in this study:

1. Serious underlying medical conditions that restrict diagnostic testing or therapy such as renal failure, congestive cardiac failure or active coexisting non-thyroid carcinoma requiring intervention before thyroid cancer is addressed.
