Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 to 80 with high-risk gastrointestinal stromal tumors that are c-Kit positive.
✕Probably not a fit
Patients with specific mutations in the PDGFRA gene or those who have previously been treated with tyrosine kinase inhibitors may not benefit from this study.

What this trial studies
This clinical trial evaluates the effectiveness of neoadjuvant therapy with imatinib mesylate in patients with high-risk gastrointestinal stromal tumors (GIST). The primary goal is to assess the 5-year progression-free survival rate following treatment. Participants must have a histologically confirmed GIST that tests positive for specific genetic markers and meet certain size criteria. The study aims to improve surgical outcomes and long-term survival rates for these patients.
Why it matters
Potential benefit: If successful, this approach could significantly improve surgical outcomes and long-term survival for patients with high-risk GIST.
How similar studies have gone: Previous studies have shown promising results with neoadjuvant imatinib therapy in improving surgical outcomes for GIST, suggesting a potential for success in this approach.
