Evaluation of DNA Methylation Signatures for the Diagnosis and Management of Thyroid Nodules
What this study is about
This clinical trial evaluates deoxyribonucleic acid (DNA) methylation signatures in diagnosing and managing thyroid nodules. The purpose of this research is to develop a new test for thyroid cancer.
View original scientific description
This clinical trial evaluates deoxyribonucleic acid (DNA) methylation signatures in diagnosing and managing thyroid nodules. The purpose of this research is to develop a new test for thyroid cancer. This test will use needle biopsies (small collections of tissue with a needle) from the thyroid to determine whether the participant has a malignant (cancer) or benign (not showing cancer) thyroid tumor. The information learned from this trial may help develop a more accurate test so that patients do not have unnecessary surgeries for nodules that are thought to be suspicious but are actually benign.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Patients without impaired decision-making capacity and who are undergoing needle biopsies for thyroid nodule diagnosis
- Over the age of 18
- Any gender, race and ethnicity
- Patients must provide informed consent prior to use of their tissues and clinical data
Exclusion criteria
- Children are excluded from the study, since the biology of children thyroid nodules is different from adults
Where
- Duarte, California
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
