Exploring second-line treatments for advanced gastrointestinal stromal tumors

Second-line Pharmacotherapy Patterns and Outcomes of Advanced Gastrointestinal Stromal Tumor: A Real-world Study

Observational First Affiliated Hospital, Sun Yat-Sen University · NCT05440357

This study is trying to see how well different second-line treatments work for people with advanced gastrointestinal stromal tumors who didn't respond to or couldn't tolerate their first treatment.

What this trial studies

This observational study aims to investigate the patterns of second-line pharmacotherapy and clinical outcomes in patients with advanced gastrointestinal stromal tumors (GIST) who have either progressed on or are intolerant to first-line treatment with imatinib. The study will collect real-world data from multiple centers to better understand the effectiveness of various second-line therapies, including sunitinib and other tyrosine kinase inhibitors. By focusing on patients with measurable lesions and specific treatment histories, the study seeks to provide insights into optimal treatment strategies for this challenging condition.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with histologically confirmed metastatic or unresectable GIST who have previously received imatinib and experienced disease progression.

Not a fit: Patients who have received two or more tyrosine kinase inhibitors or have a life expectancy of fewer than three months may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify more effective second-line treatment options for patients with advanced GIST, potentially improving their outcomes.

How similar studies have performed: Previous studies have shown varying degrees of success with second-line treatments for GIST, but this study aims to provide new insights into real-world treatment patterns and outcomes.
