What this trial studies

This prospective study aims to evaluate the effectiveness and safety of combining radiotherapy with ripretinib in patients with unresectable advanced gastrointestinal stromal tumors (GIST). The research focuses on whether this combination can prolong the time to disease progression, as ripretinib is currently the standard fourth-line treatment but has limited efficacy. The study utilizes advanced radiotherapy techniques to optimize treatment delivery, potentially improving patient outcomes. By exploring this novel approach, the study seeks to enhance the chances of surgery and improve the quality of life for patients.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 75 with unresectable advanced GIST who have progressed after multiple lines of treatment.

Not a fit: Patients with a life expectancy of less than three months or those who have previously received radiotherapy to the proposed site may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly extend the time patients with advanced GIST can live without disease progression.

How similar studies have performed: While GIST was previously thought to be insensitive to radiotherapy, emerging studies suggest that this combination approach may be effective, indicating potential for success.

Eligibility criteria
