Abstract
The standard paradigm for cancer susceptibility genetic testing has been for patients to 1) be identified by their provider as being at high risk due to extensive family history or another diagnosis (e.g., breast cancer for ovarian risk testing), and 2) attend in–person pre and post– genetic test sessions with a genetic counselor to prepare for testing and learn about the results. This arrangement places boundaries around the types of women willing to spend this time and effort receiving testing, as providers are required to act as gatekeepers to the testing process. More open methods of accessing genetic testing and providing support need to be evaluated.
We propose to deliver personal, risk–based genetic testing and results to women from the general public using the Internet. Internet–based services offer several advantages over either in–person or telephone interventions. First, information can be accessed by participants and providers on their own schedules, at any location with internet access, and can be consumed at the pace and style that is best for individual tastes and styles. If necessary, information and support can be re–reviewed if the patient does not remember the initial counseling session. Second, delivery of information through the internet can be performed in a more efficient and cost–effective manner, reserving the limited in–person genetic counseling for individuals who need it the most, while providing support to the general public about basic medical and risk–based information. Recruitment via social media outlets can directly link potential participants to the Internet systems that screen for eligibility and provide testing support. Finally, Internet delivery can bring genetic testing to the patient in their home, eliminating a major barrier to testing (multiple visits to the provider)
The main objective of MAGENTA is to test the effects of on–line genetic education versus telephone genetic counseling on cancer distress and other psychological outcomes. We will recruit women using social media and other eHealth methods to participate in a randomized trial of ovarian cancer counseling and testing that is conducted online and using the telephone. We will conduct a (2x2 factorial design) randomized trial to test online versus telephone pre– and post–test genetic counseling for ovarian cancer risk among women at higher than average risk for ovarian cancer. We expect to enroll 3000 women through our media contacts to participate in MAGENTA. For genetic risk assessment, we will evaluate and provide feedback on 19 breast and ovarian cancer (OC) genes that have a clear relationship to cancer risk in collaboration with Color Genomics. Variants include ATM, BARD1, BRCA1, BRCA2, BRIP1, CDH1, CHEK2, EPCAM, MSH2, MSH6, MLH1, NBN, PALB2, PMS2, PTEN, RAD51C, RAD51D, TP53, and STK1. We will follow women for main psychological outcomes at 3 months post testing and longer for other outcomes.
