Genetics of Breast and Ovarian Cancer (PDQ®): Genetics - Health Professional Information [NCI] - Psychosocial Issues in Inherited Breast Cancer Syndromes

continued...

The accuracy of reported family history of breast or ovarian cancer varies; some studies found levels of accuracy above 90%,[63,64] with others finding more errors in the reporting of cancer in second-degree or more distant relatives [65] or in age of onset of cancer.[66] Less accuracy has been found in the reporting of cancers other than breast cancer. Ovarian cancer history was reported with 60% accuracy in one study compared with 83% accuracy in breast cancer history.[67] Providers should be aware that there are a few published cases of Munchausen syndrome in reporting of false family breast cancer history.[68] Much more common is erroneous reporting of family cancer history due to unintentional errors or gaps in knowledge, related in some cases to the early death of potential maternal informants about cancer family history.[59] (Refer to the Taking a Family History section of the Cancer Genetics Risk Assessment and Counseling summary for more information.)

Targeted written,[69,70] video, CD-ROM, interactive computer program,[71,72,73,74,75] and culturally targeted educational materials [76,77,78] may be an effective and efficient means of increasing knowledge about the pros and cons of genetic testing. Such supplemental materials may allow more efficient use of the time allotted for pretest education and counseling by genetics and primary care providers and may discourage individuals without appropriate indication of risk from seeking genetic testing.[69]

Genetic Counseling for Hereditary Predisposition to Breast Cancer

Counseling for breast cancer risk typically involves individuals with family histories that are potentially attributable to BRCA1 or BRCA2. It also, however, may include individuals with family histories of Li-Fraumeni syndrome, ataxia-telangiectasia, Cowden syndrome, or Peutz-Jeghers syndrome.[79] (Refer to the High-Penetrance Breast and/or Ovarian Cancer Susceptibility Genes section of this summary for more information.)

Management strategies for carriers may involve decisions about the nature, frequency, and timing of screening and surveillance procedures, chemoprevention, risk-reducing surgery, and use of hormone replacement therapy (HRT). The utilization of breast conservation and radiation as cancer therapy for women who are carriers may be influenced by knowledge of mutation status. (Refer to the Clinical management of BRCA mutation carriers section of this summary for more information.)

Counseling also includes consideration of related psychosocial concerns and discussion of planned family communication and the responsibility to warn other family members about the possibility of having an increased risk of breast, ovarian, and other cancers. Data are emerging that individual responses to being tested as adults are influenced by the results status of other family members.[80,81] Management of anxiety and distress are important not only as quality-of-life factors, but also because high anxiety may interfere with the understanding and integration of complex genetic and medical information and adherence to screening.[20,21,82] The limited number of medical interventions with proven benefit to mutation carriers provides further basis for the expectation that mutation carriers may experience increased anxiety, depression, and continuing uncertainty following disclosure of genetic test results.[83] Formal, objective evaluation of these outcomes are now emerging. (Refer to the Emotional Outcomes and Behavioral Outcomes sections of this summary for more information.)
