Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with histologically-confirmed cancer harboring a rare actionable fusion.

Probably not a fit

Patients without a rare actionable fusion or those under 18 years old may not benefit from this registry.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This registry aims to document the real-life management of patients with rare actionable fusions in cancer, focusing on NTRK and other gene mutations. It involves collecting clinical data from medical files and administering a quality of life questionnaire (QLQ-C30) at the time of inclusion, during new treatments, and every six months thereafter. Patients will be followed for at least two years to better understand their treatment outcomes and quality of life. The initiative is a collaborative effort across European centers to enhance data sharing and improve patient management.

Why it matters

Potential benefit: If successful, this registry could lead to improved treatment strategies and better quality of life for patients with rare actionable fusions in cancer.

How similar studies have gone: Other studies focusing on registries for rare cancers have shown promise in improving patient outcomes and treatment strategies.
