Navigation Interventions to Improve Cascade Genetic Testing Among Relatives of Patients With Hereditary Cancer Syndromes

Summary

This clinical trial tests whether various web-based tools can help improve communication about hereditary cancer risk in families and decrease barriers to genetic testing for relatives of patients with hereditary cancer syndromes. Between 5% and 10% of all cancers are caused by genetic changes that are hereditary, which means that they run in families. Some kinds of cancer or certain cancers diagnosed in biological relatives may mean patients are more likely to have a genetic change. Once a genetic change is identified in a family, other biological relatives can choose to undergo testing themselves to better understand their cancer risk. The uptake of genetic testing in other biological relatives once a genetic condition is identified is about 20% to 30%. The Cascade Genetic Testing Platform is a virtual tool that seeks to overcome barriers related to logistics of family communication and improve dissemination of genetic testing information which is clinically actionable for individuals at highest risk for cancer. Using the Cascade Genetic Testing Platform may improve ways to share information about hereditary risk with biological relatives.

Detailed Description

03JUN2025- Amendment was approved that shorten the study timeline from 12 to 6 months. We believe this is sufficient to capture our primary outcome (participation) and a shorter timeline may keep participants more engaged. 22MAY2026- Amendment was approved adjusting enrollment goals to account for new accrual of prospective probands and their relatives, and to clarify realistic expectations for relative enrollment numbers.
