New study tests tools to help families share cancer genetic results
NCT ID NCT04763915
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
The IMPACT Study is testing two online tools—GeneSHARE and LivingLabReport—to help people with inherited cancer gene variants share their results with family members and follow cancer screening guidelines. The study involves 720 adults who have a genetic variant linked to cancers like breast, prostate, or colorectal cancer. Researchers will measure whether these tools improve family communication and guideline-based care over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- GeneSHARE web-based toolkit and LivingLabReport website
- What this could lead to
- If successful, this could lead to better ways for people with inherited cancer risks to communicate with family and follow recommended screenings.
- What could go wrong
- This is a behavioral study, not a drug trial, so it won't directly treat or cure cancer. Results depend on participants' willingness to use the tools and share information.

Randomized Controlled Trial Eligibility: All trial participants will be autonomous adults who are capable of participating in the study Inclusion Criteria: * English-speaking men and women aged 18 years or older * Not adopted (i.e., have information about their biological relatives) * Have access to internet and a computer, tablet, or smartphone * Documented pathogenic/likely pathogenic variant in an inherited cancer gene that has CRM guidelines listed in the National Comprehensive Cancer Network (NCCN) Genetic/Familial Panel focused on Breast, Ovarian, and Pancreatic or Colorectal cancers * Must meet at least one of the following criteria: * Intervention A (GeneSHARE) criteria: Have at least one at-risk adult, living relative who either: * has not been told about the genetic test result by the participant * has not had their own genetic testing * Intervention B (LivingLabReport) criteria: Are non-adherent (i.e., either undertreatment or overtreatment) to at least one of the current NCCN CRM guidelines or if currently adherent, require ongoing cancer screening VUS Pilot Study Eligibility: All VUS pilot study participants will be autonomous adults who are capable of participating in the study. Eligibility criteria include: * English-speaking men and women aged 18 years or older * Not adopted (i.e., have information about their biological relatives) * Have access to internet and a computer, tablet, or smartphone * Documented VUS in an inherited cancer gene
