What this trial studies

This observational study aims to follow individuals diagnosed with gastrointestinal stromal tumors (GISTs) and collect tumor tissue samples for laboratory analysis. Participants aged 6 and older will undergo medical history reviews, physical exams, and may have genetic counseling and testing. The study will also involve blood samples, cheek swabs, and imaging studies like CT and MRI scans. Participants will be monitored at the NIH Clinical Center for up to 10 years to assess disease progression and support translational research.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 6 and older with a confirmed diagnosis of gastrointestinal stromal tumors.

Not a fit: Patients with non-modifiable medical comorbidities that would prevent them from undergoing necessary surgical procedures may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and treatment options for patients with GISTs, particularly those with wild-type and treatment-resistant tumors.

How similar studies have performed: Other studies have shown success in utilizing tumor tissue for genomic analysis and drug research, making this approach promising yet still requiring further exploration.
