Living longer with GIST: what are the hidden costs?
NCT ID NCT07522762
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 330 adults with advanced or metastatic GIST who have been on targeted therapy (TKIs) for at least 2 years. Researchers will track quality of life, treatment side effects, and financial burdens over up to 10 years. The goal is to better understand the real-world challenges these long-term survivors face, not to test a new treatment.
