Can a registry help more families get tested for cancer genes?
NCT ID NCT07626814
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at 545 people with hereditary cancer syndromes and their relatives. It compared the usual method of asking patients to share testing information with family members to a new method where a registry also sends reminders. The goal was to see if the registry-aided approach increases the number of relatives who get tested for cancer genes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could show that a registry-aided approach helps more family members get tested for cancer risk, potentially catching cancers earlier.
- What could go wrong
- This is a completed study comparing two communication methods, not testing a new treatment. Results may not apply to all populations or healthcare systems.
