Brief Summary:

Background:

About 5% to 10% of differentiated thyroid cancers become resistant to standard treatment with radioactive iodine. In these cases, treatment options are limited and generally not effective. Researchers want to see if they can better detect thyroid tumors by using a compound called 68Gallium-DOTATATE. This compound may bind to a tumor and make it visible during a positron emission tomography/computed tomography (PET/CT) scan. This information might help guide future research and treatment.

Objective:

To identify the people with thyroid cancer whose tumors have a high uptake of 68Gallium-DOTATATE as analyzed by imaging with PET/CT.

Eligibility:

People ages 18 years and older with thyroid cancer that has spread outside of the thyroid.

Design:

Participants will have a medical exam. They will give blood and urine samples. Some samples will be used for research.

Participants will have imaging scans that follow standard of care. These scans may include:

CT scan of the neck, chest, abdomen, and pelvis

Bone scan

Magnetic resonance imaging of the brain, spine, or liver

18-FDG-PET/CT as needed

Participants will have a PET/CT scan. They will get an intravenous (IV) line. They will get an IV injection of 68Gallium-DOTATATE. It contains radioactive tracers. The PET/CT scanner is shaped like a large donut. It contains crystals. The crystals pick up small radiation signals that are given off by the tracers. The CT part of the scan uses low-dose x-rays. The pictures made by the scanner show where the tracers are in the body. The session will last 90 minutes.

Participation will last for about 3 months.


Condition or disease Intervention/treatment Phase
Metastic Thyroid Cancer Drug: 68-Gallium-DOTATATE-PET/CT Phase 2

Detailed Description:

The study is designed to identify the patients with metastatic radioactive iodine (RAI) non-avid or non-responsive thyroid cancer RAI non-responsive Hurthle cell thyroid cancer (HTC), differentiated thyroid cancer (DTC) and metastatic medullary thyroid cancer (MTC), whose tumors are

characterized by a high expression of somatostatin receptors type 2 (SSTR2) by a one-time experimental imaging using 68Gallium(68Ga)-DOTATATE Positron Emission Tomography/Computed Tomography (PET/CT) scan. Participants will also undergo standard of care imaging per ATA

guidelines. Both the experimental 68Ga-DOTATATE PET/CT scan and the standard of care imaging will be performed within a 3 month timeframe.

The main goal is to compare the prevalence of patients with metastatic RAI-non-avid or RAI-non-responsive thyroid cancer whose tumors are characterized by a high SSTR2 expression by imaging with 68Ga-DOTATATE PET/CT between three groups: (1) Group HTC - the molecularly and

histologically unique subtype of differentiated thyroid cancer (DTC) - Hurthle cell thyroid cancer (HTC), (2) Group DTC - patients with remaining histological types of DTC, and (3) Group MTC -- patients with metastatic thyroid cancer of neuroendocrine origin - medullary thyroid cancer

(MTC). The Second goal of this study is to analyze the associate between the 68Ga-DOTATATE uptake and molecular signature of thryoid cancer and tumor volume, and to create a repository of data for future research in thyroid cancer.

Arm Intervention/treatment
Experimental: Differentiated thyroid cancer (DTC)
Patients with DTC but not HTC
Drug: 68-Gallium-DOTATATE-PET/CT
68Ga-DOTATATE is administered one-time via intravenous injection of 5 mCi in a volume of 3-5 ml containing up to 50 mcg [68Ga] DOTATATE.

Experimental: Hurthle cell thyroid cancer (HTC)
Molecularly and histologically unique subtype of DTC - Hurthle cell thyroid cancer (HTC),
Drug: 68-Gallium-DOTATATE-PET/CT
68Ga-DOTATATE is administered one-time via intravenous injection of 5 mCi in a volume of 3-5 ml containing up to 50 mcg [68Ga] DOTATATE.

Experimental: Medullary thyroid cancer (MTC)
Patients with metastatic thyroid cancer of neuroendocrine origin - medullary thyroid cancer (MTC)
Drug: 68-Gallium-DOTATATE-PET/CT
68Ga-DOTATATE is administered one-time via intravenous injection of 5 mCi in a volume of 3-5 ml containing up to 50 mcg [68Ga] DOTATATE.




Primary Outcome Measures :
  1. Prevalence of patients with metastatic RAI-non-avid or RAI-non-responsive thyroid cancer whose tumors are characterized by a high SSTR2 expression by imaging with 68Ga-DOTATATE PET/CT [ Time Frame: During baseline assessment ]
    Prevalence of thyroid cancer patients characterized by a high SSTR2 expression in at least one metastatic lesion per patient documented by SUVmax of 68Ga-DOTATATE-PET/CT of above 15 among patients with metastatic HTC, DTC and MTC.


Secondary Outcome Measures :
  1. Correlation between tumor volume and SUV max for each participant [ Time Frame: During baseline assessment ]
    Tumor volume in cm3 as measured by the ellipsoid formula will be measured on up to 10 lesions per organ and correlated with SUVMax

  2. Maximum standard uptake value (SUVmax) of 68Ga-DOTATATE [ Time Frame: During baseline assessment ]
    SUVmax will be compared in groups based on the somatic mutation status in primary tumors: BRAF-like, RAS-like, harboring mitochondrial DNA mutations and /or RET protooncogene mutation.
