Is this trial a fit for you?

Likely a good fit

Ideal candidates are Canadian residents aged 18 and older with malignant tumors that have been molecularly tested and identified to have rare alterations.

Probably not a fit

Patients who do not have molecular testing completed or those with common tumor types may not benefit from this study.

What this trial studies

This study collects data on Canadian cancer patients who have rare genetic changes in their tumors, which may respond to specific cancer therapies. It aims to create a cohort to understand the natural history of these cancers and compare treatment outcomes, including effectiveness and side effects, across different therapies. The study will also investigate the incidence and outcomes of specific patterns of cancer spread, such as brain metastases, and analyze real-world treatment patterns over time. By focusing on molecularly subtyped tumors, the study seeks to optimize treatment responses and improve patient survival.

Why it matters

Potential benefit: If successful, this study could lead to more effective and personalized cancer treatments for patients with rare molecular alterations.

How similar studies have gone: Other studies have shown success in targeting therapies based on molecular alterations, indicating a promising approach in this area.
