This research project is in progress. PCORI will post the research findings on this page within 90 days after the results are final.
What is the research about?
Some types of cancer are hereditary. With hereditary cancers, people may have many family members who had cancer, or they may have a gene mutation that causes cancer. About 1 in 10 people in the United States are at risk of hereditary cancer. People with this risk often get cancer at a young age.
One way for doctors to find out if a patient is at risk for hereditary cancer is to ask about the patient’s family history. In this type of screening, patients answer questions about their health history and the health of their relatives. Doctors can use different methods to get patients’ family history. These methods vary in
- How accurate they are
- How easy they are to use
- How well they work to identify people at risk for hereditary cancer who should have genetic testing and cancer screening
- How much anxiety about cancer risk people have as a result of talking about their family history
In this study, the research team is looking at three ways to collect family histories to compare their effectiveness.
Who can this research help?
Healthcare systems may be able to use the results when considering the best ways to identify and provide care for patients at risk for hereditary cancer.
What is the research team doing?
The research team is enrolling 18,000 members of a large healthcare system. The team is assigning patients by chance to one of three groups. Patients in the first group receive usual care. In this group, the doctor asks patients about their family history and provides follow-up care as needed.
Patients in both the second and third groups complete an online family history form. In the second group, patients complete a brief version. This version identifies people at highest risk of hereditary breast and colorectal cancer only; it takes about 10 minutes to complete. In the third group, patients complete a detailed, three-generation family history form. This version takes more time but collects more information to guide care. Patients in both the second and third groups receive cancer screening and follow-up care from a genetic counselor as needed.
The research team is looking at how well each screening method identifies patients at risk for hereditary cancer. The team also wants to know about any negative effects, such as anxiety. Finally, the team is looking at health records to see how many patients
- Successfully report their family history
- Complete recommended cancer screening
- Get recommended genetic testing
Patients, advocacy groups, clinicians, and health insurers are providing input on all aspects of the study.
