Could your family history hold the key to thyroid cancer risk?
NCT ID NCT02747888
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to uncover genetic factors that increase the risk of thyroid cancer, especially in children and families with a strong history of the disease. Researchers will collect medical history and blood or saliva samples from 250 participants to look for inherited gene changes. The goal is to better understand why some people develop thyroid cancer, not to test a new treatment.

Inclusion Criteria: * Individual pediatric patient with current or previous known or suspected thyroid cancer or nodule(s). * Individual adult patient with current or previous known or suspected thyroid cancer or nodule(s) if they come from a family with a high suspicion of hereditary cancer (as below). * Individuals from families with a high suspicion of hereditary thyroid cancer: * Families with a current or previous diagnosis of a thyroid cancer/nodule occurring in childhood (\<18 years old). * Families with a high suspicion of hereditary thyroid cancer/nodules other than above to include: * Families with thyroid cancer in multiple individuals * Families with thyroid cancer and a known genetic syndrome * Families with thyroid cancer and a suspected genetic syndrome (e.g. multiple childhood cancers in the family, multiple primary cancers, multiple endocrinopathies, etc.) Exclusion Criteria: * Individuals who are unable to give informed consent. * Individuals who are unable to complete study materials.
