- Brief Summary
Individuals living in geographically underserved areas encounter considerable barriers to access of quality cancer genetic services. Although in-person genetic counseling has generally been accepted as the standard of care, the use of telecommunications to deliver clinical genetic services may help reduce this disparity in access to such services. However, before the widespread adoption of telephone-delivered cancer genetic services occurs, it is critical to analyze the efficacy and safety of this mode of communication. This two-group randomized equivalency/non-inferiority trial will determine whether telephone-based cancer genetic counseling is an acceptable alternative to the traditional in-person mode among women who have a personal or family history of breast and/or ovarian cancer strong enough to warrant genetic counseling and testing. This study's findings will provide important information to cancer centers and cancer control policies about the safety, efficacy, and costs of delivering telephone-based clinical cancer genetic services for geographically challenged women at risk for having Breast Cancer susceptibility gene (BRCA) 1/2 mutations.
- Detailed Description
Following confirmation of eligibility and completion of baseline surveys, participants will be randomly assigned to one of the study arms by the project coordinator, using a computer-generated allocation algorithm on the basis of a randomization blocks method using four, six or eight participants in each block.
In-person and telephone counseling will be delivered by the same board-certified genetic counselors using a guideline-concordant semi-structured protocol that will allow for personalization of counseling.
Participants randomly assigned to telephone counseling will be mailed packets that include a sealed envelope containing an educational brochure about hereditary breast and ovarian cancer genetic counseling with visual aids. At the time of their session, participants will review the brochure and genetic counselors will use visual aids to explain breast-ovarian cancer genetics. Women receiving in-person counseling will be given the same materials during their session at the community clinic.
For women who elect to have testing, those who have telephone counseling will be sent a genetic test kit; those who have in-person counseling will have the option of giving a sample immediately at the clinic, or will be given a test kit with the same instructions as those in the telephone-counseling group.
When BRCA test results become available, participants will be offered individual post-test counseling with the same genetic counselor who conducted the pretest session.

Group Intervention Description In-person genetic counseling In-Person Genetic Counseling In-person BRCA1/BRCA2 genetic counseling is delivered by board-certified genetic counselors using a guide-line-concordant semistructured protocol that allows for personalization of counseling and is similar to that used by others. All sessions are audiotaped for treatment fidelity assessments. In-person and telephone counseling are delivered by the same five board-certified genetic counselors. Telephone genetic counseling Telephone Genetic Counseling Participants randomly assigned to telephone counseling are mailed packets that included a sealed envelope containing an educational brochure about hereditary breast and ovarian cancer (HBOC) genetic counseling with visual aids. At the time of their session, participants open their envelope and counselors use the visual aids to explain breast-ovarian cancer genetics and administer BRCA1/BRCA2 genetic counseling. Women receiving in-person counseling are given these same materials during their session at the community clinic. In-person and telephone counseling are delivered by the same five board-certified genetic counselors.
- Primary Outcome Measures
Name Time Method Determine the non-inferiority/equivalency of telephone genetic counseling to standard in-person genetic counseling 6 &12-month follow-up 1. Compare utilization of BRCA1/BRCA2 testing among telephone genetic counseling relative to in-person genetic counseling.
2. Determine the safety and efficacy of telephone genetic counseling relative to in-person genetic counseling by evaluating psychological and quality of life outcomes.
3. Compare communication-related and decision-making outcomes among telephone genetic counseling relative to in-person genetic counseling.
- Secondary Outcome Measures
Name Time Method Determine the feasibility of the intervention 1 week pre-test, 1 week post-test, 6 & 12 month follow-ups 1. Examine the intervention delivery and patient costs of telephone genetic counseling relative to in-person genetic counseling.
2. Examine mediators (sociodemographic, communication factors, health care access, clinical, \& psychosocial factors) of genetic testing decisions, and affective and cognitive outcomes.
3. Compare decisions and perceptions about use of primary/secondary prevention strategies for hereditary breast/ovarian cancer.
