The Role of 68-Gallium-DOTATATE-PET/CT in the Imaging of Metastatic Thyroid Cancer

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.

Natural History Study of Children and Adults With Medullary Thyroid Cancer

Background: - Medullary thyroid cancer (MTC) is a rare cancer of the thyroid gland. In children and adults, it is often part of a condition called Multiple Endocrine Neoplasia 2 (MEN2). MEN2 is usually caused by a genetic mutation, and it can cause a number of problems in addition to MTC. These problems include adrenal gland tumors, hormone changes, and problems with the bones and other organs. Not much is known about how MTC develops over time, especially in people with MEN2. Researchers want to study MTC in children and adults and see how it affects their growth and development. Objectives: - To study how medullary thyroid cancer affects children and adults over time. Eligibility: - Children and adults who have medullary thyroid cancer. Design: Participants will be screened with a brief physical exam and medical history. Blood and tissue samples will be collected to see whether participants have the MEN2 genetic mutation. Treatment will not be provided as part of this study. However, participants will be receiving standard care for MTC. They may be eligible for other clinical trials at the National Institutes of Health. Participants will have regular study visits every 6 to 12 months to evaluate their MTC and any treatment. Blood tests, imaging studies, and other tests may be performed as needed to monitor the disease. Participants and their parents/guardians will also complete questionnaires about their health and emotions during the study.

Disorders of Bone and Mineral Metabolism

Background: Disorders of bone and mineral metabolism particularly parathyroid disorders like multiple endocrine neoplasia type 1, jaw tumor syndrome, familial hypocalciuric hypercalcemia, parathyroid cancer, osteoporosis, and Paget s disease. Advances have been made in the past few decades. But, there remains a significant gap in the knowledge about these disorders. Researchers want to collect information from people with these disorders to learn more. Objective: To create a collection of data and samples that researchers can use for studies of bone and mineral metabolism or other related diseases or conditions. Eligibility: People ages 6 months or older who have or are at risk of having a bone and mineral metabolism disorder. Design: Participants will be screened with a review of their medical records. Participants will be seen, tested, and treated by doctors based on their condition. Their visits may be in person or via telehealth. Participants will complete questionnaires. They will answer questions about their physical, mental, and social health. Participants may give samples such as saliva, blood, urine, or stool. Participants may give cheek cell samples. They will do this using a cheek swab or by spitting into a cup. Adult participants may give a skin biopsy. For this, a small bit of skin is removed with a punch tool. Participants may have medical photos taken. If participants have surgery during the course of their regular care either at the NIH or at a different hospital or doctor s office, researchers will ask for some of the leftover tissue. Participants will remain in the study indefinitely and may be followed longitudinally on a as needed basis.
