Understanding rare solid tumors and their genetic factors

Natural History and Biospecimen Acquisition Study for Children and Adults With Rare Solid Tumors

National Institutes of Health Clinical Center (CC) · NCT03739827

This study is looking to learn more about rare solid tumors and their genetic factors by collecting samples and medical histories from people who have these tumors to help improve future treatments and prevention.

What this trial studies

This observational study aims to investigate the natural history and genetic characteristics of rare solid tumors by collecting biological samples and medical histories from affected individuals. Participants will be screened based on their medical and family histories, and those with rare tumors will have their medical records reviewed. The study seeks to gather valuable data that could lead to improved screening, prevention, and treatment strategies for rare cancers.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with rare solid tumors, those with a family history of such tumors, or individuals with genetic variants predisposing them to rare tumors.

Not a fit: Patients with common solid tumors or those without any genetic predisposition to rare tumors may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of rare solid tumors, leading to better screening and treatment options for patients.

How similar studies have performed: Previous studies on rare tumors have shown that even non-interventional research can lead to significant advancements in understanding and treating these conditions.
