Counseling Paired With Comprehensive Genetic Cancer Screening May Increase Knowledge and Decrease Anxiety Among At-Risk Patients, Penn Study Finds

Results Highlight Importance of Pre- and Post-Test Counseling for Multiplex Testing

PHILADELPHIA –Many BRCA 1/2-negative patients choose to proceed with comprehensive testing for genetic mutations that increase cancer risk, and when presented with counseling before and after testing, most make informed decisions and experience decreased levels of anxiety, according to new research from the Perelman School of Medicine at the University of Pennsylvania and the Basser Center for BRCA in Penn’s Abramson Cancer Center. The study will be presented on Thursday, December 10, 2015 as part of the 2015 San Antonio Breast Cancer Symposium (Abstract #P2-09-01).

“Although comprehensive genetic testing is becoming more widely available, the potential benefits and risks for patients are unknown,” said lead author Angela R. Bradbury, MD, an assistant professor of Hematology/Oncology in Penn’s Abramson Cancer Center. “The new study shows that when providing patients with counseling both before and after testing, most report an increase in knowledge, and decreases in anxiety and uncertainty after learning the test results.”

To date, 124 women with a personal or family history of breast or ovarian cancer who have tested negative for the cancer causing BRCA1 and BRCA2 genes have participated in the study. Of the 95 who have completed pre-test counseling with a certified genetic counselor, 93 percent elected to move forward with multiplex testing, which allows for the simultaneous analysis of alterations in 25 cancer-related genes, and is an alternative to targeted tests that screen for individual forms of cancer. A targeted test might look only for inherited mutations in the BRCA1 and BRCA2 genes, for example.

After testing, patients experienced declines in in general anxiety, and an improvements in genetic knowledge. However, patient experiences may vary by test result with the potential for short-term increases in anxiety and sustained uncertainty for those who test positive, which the authors suggest may be a result of the limited amount of information available for some of the mutations.

“There’s much we don’t know about some of the genes these panel tests examine,” said Susan M. Domchek, MD, executive director of the Basser Center for BRCA and senior author on the study. “While it can be reassuring to hear that you don’t have these mutations, we may not have a lot of information or effective treatment plans for some patients with a mutation in a cancer susceptibility gene. “In those cases, patients are sometimes left with little choice but to wait until additional research helps guide management for their situations.”

Other Penn authors on the study include Kara N. Maxwell, Amanda Brandt, Jamie Brower, Laura DiGiovanni, Jessica M. Long, Jaquelyn Powers, Jill Stopfer, and Katherine Nathanson.

Penn Medicine is one of the world's leading academic medical centers, dedicated to the related missions of medical education, biomedical research, and excellence in patient care. Penn Medicine consists of the Raymond and Ruth Perelman School of Medicine at the University of Pennsylvania (founded in 1765 as the nation's first medical school) and the University of Pennsylvania Health System, which together form a $5.3 billion enterprise.

The Perelman School of Medicine has been ranked among the top five medical schools in the United States for the past 18 years, according to U.S. News & World Report's survey of research-oriented medical schools. The School is consistently among the nation's top recipients of funding from the National Institutes of Health, with $373 million awarded in the 2015 fiscal year.

The University of Pennsylvania Health System's patient care facilities include: The Hospital of the University of Pennsylvania and Penn Presbyterian Medical Center -- which are recognized as one of the nation's top "Honor Roll" hospitals by U.S. News & World Report -- Chester County Hospital; Lancaster General Health; Penn Wissahickon Hospice; and Pennsylvania Hospital -- the nation's first hospital, founded in 1751. Additional affiliated inpatient care facilities and services throughout the Philadelphia region include Chestnut Hill Hospital and Good Shepherd Penn Partners, a partnership between Good Shepherd Rehabilitation Network and Penn Medicine.

Penn Medicine is committed to improving lives and health through a variety of community-based programs and activities. In fiscal year 2015, Penn Medicine provided $253.3 million to benefit our community.
