Strength of Recommendations and Quality of Evidence
These recommendations apply to women who have not received a diagnosis of breast or ovarian cancer. They do not apply to women with a family history of breast or ovarian cancer that includes a relative with a known deleterious mutation in BRCA1 or BRCA2 genes; these women should be referred for genetic counseling. These recommendations do not apply to men.
Although there currently are no standardized referral criteria, women with an increased-risk family history should be considered for genetic counseling to further evaluate their potential risks.
Certain specific family history patterns are associated with an increased risk for deleterious mutations in the BRCA1 or BRCA2 gene. Both maternal and paternal family histories are important. For non-Ashkenazi Jewish women, these patterns include 2 first-degree relatives with breast cancer, 1 of whom received the diagnosis at age 50 years or younger; a combination of 3 or more first- or second-degree relatives with breast cancer regardless of age at diagnosis; a combination of both breast and ovarian cancer among first- and second-degree relatives; a first-degree relative with bilateral breast cancer; a combination of 2 or more first- or second-degree relatives with ovarian cancer regardless of age at diagnosis; a first- or second-degree relative with both breast and ovarian cancer at any age; and a history of breast cancer in a male relative.
For women of Ashkenazi Jewish heritage, an increased-risk family history includes any first-degree relative (or 2 second-degree relatives on the same side of the family) with breast or ovarian cancer.
About 2 percent of adult women in the general population have an increased-risk family history as defined here. Women with none of these family history patterns have a low probability of having a deleterious mutation in BRCA1 or BRCA2 genes.
Computational tools are available to predict the risk for clinically important BRCA mutations (that is, BRCA mutations associated with the presence of breast cancer, ovarian cancer, or both), but these tools have not been verified in the general population. There is no empirical evidence concerning the level of risk for a BRCA mutation that merits referral for genetic counseling.
Not all women with a potentially deleterious BRCA mutation will develop breast or ovarian cancer. In a woman who has a clinically important BRCA mutation, the probability of developing breast or ovarian cancer by age 70 years is estimated to be 35 percent to 84 percent for breast cancer and 10 percent to 50 percent for ovarian cancer.
Appropriate genetic counseling helps women make informed decisions, can improve their knowledge and perception of absolute risk for breast and ovarian cancer, and can often reduce anxiety. Genetic counseling includes elements of counseling; risk assessment; pedigree analysis; and, in some cases, recommendations for testing for BRCA mutations in affected family members, the presenting patient, or both. It is best delivered by a suitably trained health care provider.
A BRCA test is typically ordered by a physician. When done in concert with genetic counseling, the test assures the linkage of testing with appropriate management decisions. Genetic testing may lead to potential adverse ethical, legal, and social consequences, such as insurance and employment discrimination; these issues should be discussed in the context of genetic counseling and evaluation for testing.
Among women with BRCA1 or BRCA2 mutations, prophylactic mastectomy or oophorectomy decreases the incidence of breast and ovarian cancer; there is inadequate evidence for mortality benefits. Chemoprevention with selective estrogen receptor modulators may decrease incidence of estrogen receptor-positive breast cancer; however, it is also associated with adverse effects, such as pulmonary embolism, deep venous thrombosis, and endometrial cancer. Most breast cancer associated with BRCA1 mutations is estrogen receptor-negative and thus is not prevented by tamoxifen. Intensive screening with mammography has poor sensitivity, and there is no evidence of benefit of intensive screening for women with BRCA1 or BRCA2 gene mutations. Magnetic resonance imaging (MRI) may detect more cases of cancer, but the effect on mortality is not clear.
Women with an increased-risk family history are at risk not only for deleterious BRCA1 or BRCA2 mutations but potentially for other unknown mutations as well. Women with an increased-risk family history who have negative results on tests for BRCA1 and BRCA2 mutations may also benefit from surgical prophylaxis.
The USPSTF has made recommendations on mammography screening for breast cancer, screening for ovarian cancer, and chemoprevention of breast cancer, which can be accessed at http://www.uspreventiveservicestaskforce.org.
Breast and ovarian cancer are associated with a family history of these conditions. Approximately 5 percent to 10 percent of women with breast cancer have a mother or sister with breast cancer, and up to 20 percent have a first-degree or a second-degree relative with breast cancer.1-6 Germline mutations in 2 genes, BRCA1 and BRCA2, have been associated with an increased risk for breast cancer and ovarian cancer.7,8 Specific BRCA mutations (founder mutations) are clustered among certain ethnic groups, such as Ashkenazi Jews, and among families in the Netherlands, Iceland, and Sweden.1
Several characteristics are associated with an increased likelihood of BRCA mutations.1,9-12 These include breast cancer diagnosed at an early age, bilateral breast cancer, history of both breast and ovarian cancer, presence of breast cancer in 1 or more male family members, multiple cases of breast cancer in the family, both breast and ovarian cancer in the family, 1 or more family members with 2 primary cases of cancer, and Ashkenazi Jewish background. No direct measures of the prevalence of clinically important BRCA1 or BRCA2 mutations in the general, non-Jewish U.S. population have been published; however, models have estimated it to be about 1 in 300 to 500.13-16 Prevalence estimates in a large study of individuals from referral populations with various levels of family history ranged from 3.9 percent (no breast cancer diagnosed in relatives <50 years of age and no ovarian cancer) to 16.4 percent (breast cancer diagnosed in a relative <50 years of age and ovarian cancer diagnosed at any age).17
Penetrance is the probability of developing breast or ovarian cancer in women who have a BRCA1 or BRCA2 mutation. Published reports of penetrance describe estimates of BRCA1 and BRCA2 mutations ranging from 35 percent to 84 percent for breast cancer and 10 percent to 50 percent for ovarian cancer, calculated to age 70 years, for non-Ashkenazi Jewish women or those unselected for ethnicity.1,13,14,18-22 Among Ashkenazi Jewish women, penetrance estimates range from 26 percent to 81 percent for breast cancer and 10 percent to 46 percent for ovarian cancer.1,23-29 Estimates are higher for relatives of women with cancer diagnosed at younger ages, for women from families with greater numbers of affected relatives (when based on data from families selected for breast and ovarian cancer), and when certain methods of analysis are used.
A systematic review of the evidence found no population-based randomized, controlled trials of risk assessment and BRCA mutation testing using the outcomes of incidence of breast and ovarian cancer or cause-specific mortality.1 The USPSTF therefore examined the chain of evidence for accuracy of risk assessment tools, efficacy of preventive interventions, and the harms of screening and interventions.
Although several tools to predict risk for deleterious BRCA mutations have been developed from data on previously tested women, no studies of their effectiveness in a primary care screening population are available.30 These risk tools include the Myriad Genetic Laboratories model, the Couch model, BRCAPRO, and the Tyrer model.1 Much of the data used to develop the models are from women with existing cancer, and their applicability to asymptomatic, cancer-free women in the general population is unknown. Three tools have been developed to guide primary care clinicians in assessing risk and guiding referral: the Family History Risk Assessment Tool (FHAT), the Manchester scoring system, and the Risk Assessment in Genetics (RAGs) tool.31 The sensitivity and specificity of FHAT for a clinically important BRCA1 or BRCA2 mutation were 94 percent and 51 percent, respectively. The Manchester scoring system was developed in the United Kingdom to predict deleterious BRCA1 or BRCA2 mutations at the 10 percent likelihood level and had an 87 percent sensitivity and a 66 percent specificity.32 The RAGs tool, a computer program designed to support assessment and management of family breast and ovarian cancer in primary care settings,33 is used to assign patients to categories of low risk (<10 percent), moderate risk (10 percent to 25 percent), and high risk (>25 percent). Primary care clinicians can then manage recommendations of reassurance, referral to a breast clinic, or referral to a geneticist on the basis of the patient's respective risk categories.34
The interventions that can be offered to a woman with a deleterious BRCA1 or BRCA2 mutation or other increased risk for hereditary breast cancer include intensive screening, chemoprevention, prophylactic mastectomy or oophorectomy, or a combination. Overall, evidence on the efficacy of intensive surveillance of BRCA1 and BRCA2 carriers to reduce morbidity or mortality is insufficient. Recent descriptive studies report increased risk for interval cancer (cancer occurring between mammograms) in BRCA-positive patients with and without previous cancer who were receiving annual mammographic screening. This indicates that annual mammography may miss aggressive cancer in carriers of the BRCA mutation.1
Good evidence shows that MRI has higher sensitivity for detecting breast cancer among women with a BRCA1 or BRCA2 mutation than does mammography, clinical breast examination, or ultrasonography. One study compared these screening methods in 236 Canadian women 25 to 65 years of age who had BRCA1 or BRCA2 mutations.35 The women underwent 1 to 3 annual screening examinations, including MRI, mammography, and ultrasonography, and received clinical breast examinations every 6 months. The researchers found that MRI was more sensitive for detecting breast cancer (sensitivity, 77 percent; specificity, 95.4 percent) than mammography (sensitivity, 36 percent; specificity, 99.8 percent), ultrasonography (sensitivity, 33 percent; specificity, 96 percent), or clinical breast examination alone (sensitivity, 9 percent; specificity, 99.3 percent). However, use of MRI, ultrasonography, and mammography in combination had the highest sensitivity, at 95 percent. The effect of this increased detection on morbidity and mortality remains unclear. Expert groups recommend intensive screening for breast cancer in patients with the BRCA mutation.36
The evidence is also insufficient to determine the morbidity and mortality effects of intensive screening for ovarian cancer among women with BRCA1 or BRCA2 mutations. One study in which 1610 women with a family history of ovarian cancer were screened with transvaginal ultrasonography showed a high rate of false-positive results (only 3 of 61 women with abnormal scans had ovarian cancer).37
Good-quality evidence from 4 randomized, controlled trials shows that prophylactic tamoxifen reduces the risk for estrogen receptor-positive breast cancer in women without previous breast cancer.38,39 A meta-analysis of these trials showed a relative risk for total breast cancer of 0.62 (95 percent CI, 0.46 to 0.83).1 Further analysis of the largest of these trials showed a possible reduction in breast cancer incidence for women with BRCA2 mutations but not those with BRCA1 mutations, possibly because women with BRCA1 mutations had predominantly estrogen receptor-negative tumors. Conclusions are difficult to draw because of the small number of breast cancer cases in this analysis.40
Fair-quality evidence is available on the effectiveness of prophylactic surgery to prevent breast and ovarian cancer. Cohort studies of prophylactic surgery have several methodologic limitations that should be considered when interpreting and generalizing their results, such as selection bias, retrospective study design, lack of a control group for estimation of benefit-attributable outcome in the untreated group, and inability to define risk reduction attributable to mastectomy in patients electing to have both mastectomy and oophorectomy.41 Four published studies (2 of fair quality and 2 that did not meet USPSTF quality criteria) of prophylactic bilateral mastectomy in high-risk women show a consistent 85 percent to 100 percent reduction in risk for breast cancer despite differences in study designs and comparison groups (for example, sisters,42 matched controls,43 a surveillance group,44 and penetrance models45). Four studies of prophylactic oophorectomy reported reduced risks for ovarian and breast cancer,46-49 although the number of cases was small and the confidence intervals for the only prospective study crossed 1.0 for both outcomes.50 Overall, oophorectomy reduced ovarian cancer risk by 85 percent to 100 percent and reduced breast cancer risk by 53 percent to 68 percent.
No studies have described cancer incidence or mortality outcomes associated with genetic counseling, although 10 fair- to good-quality randomized, controlled trials reported psychological and behavioral outcomes.1 These studies examined the impact of genetic counseling on worrying about breast cancer, anxiety, depression, perception of cancer risk, and intention to participate in genetic testing. Studies were conducted in highly selected samples of women, and results may not be generalizable to a screening population. Five of 7 trials showed that breast cancer worry decreased after genetic counseling, and 2 studies showed no significant effect.1 Three studies reported decreased anxiety after genetic counseling, and 3 reported no significant effect. One study reported decreased depression after genetic counseling, and 4 found no significant effect.1 Results of a meta-analysis showed that genetic counseling significantly decreased generalized anxiety, although the reduction in psychological distress was not significant.51 There is poor evidence (conflicting studies) regarding whether genetic counseling increases or decreases the accuracy of patients' risk perception.
The USPSTF examined the available evidence on harms of screening and intervention. Approximately 12 percent of high-risk families without a BRCA1 or BRCA2 coding-region mutation may have other clinically important genomic rearrangements.52 Approximately 13 percent of tests report mutations of unknown significance; however, the harms associated with such test results are not known.53 Routine referral for genetic counseling and consideration of BRCA1 and BRCA2 testing clearly has important psychological, ethical, legal, and social implications, although they are not well quantified in the literature. Among these are the potential for burdening patients with the knowledge of mutations of unknown importance and the potential for affecting family members other than the individual patient. The potential harms of intensive screening include overdiagnosis and overtreatment. There is good-quality evidence on the harms of prophylactic tamoxifen,1 including thromboembolic events, endometrial cancer, and hot flashes. Fair-quality evidence shows that prophylactic mastectomy can cause hematoma, infection, contracture, or implant rupture (with reconstruction) and that prophylactic oophorectomy can cause infection, bleeding, urinary tract or bowel injury, and premature menopause. Overall, the USPSTF estimates that the magnitude of these potential harms is at least small.
Population studies are needed to determine the prevalence and penetrance of various mutations in the BRCA gene and the factors that influence penetrance for women with these mutations. Research has focused on highly selected women in referral centers and has generally reported short-term outcomes. Issues requiring additional study include the effectiveness of risk stratification and genetic counseling when delivered in different settings and by different types of providers, appropriate training for counselors, use of system supports, and patient acceptance of educational strategies. The impact of BRCA testing on ethical, legal, and social issues needs to be better clarified. We also need to understand the effect of genetic counseling on the emotions and behavior of the patient and her first-degree female relatives.
Enhanced screening with such methods as MRI needs to be better studied in high-risk women. Future studies should examine the impact of intensive MRI screening on breast cancer mortality and on possible overtreatment. Studies specifically designed to examine the potential benefit of preventive medication in women with known deleterious BRCA mutations are essential to establish whether there are any effective alternatives to prophylactic surgery. There is a paucity of data on BRCA-associated ovarian cancer; further research in screening and management of women at high risk for ovarian cancer is needed. It would be helpful to develop and validate tools feasible for use in primary care practice that would help clinicians make appropriate referrals for genetic counseling.
Recommendations of Other Groups
A few organizations have made recommendations on genetic susceptibility testing. The American College of Medical Genetics (ACMG) recommends risk assessment and genetic counseling before testing for BRCA1/BRCA2 mutations in individuals at increased risk, based on a personal or family history of breast cancer, ovarian cancer, or both.54 In a previous guideline published in 1996, the ACMG recommended testing for BRCA1 mutations in high-risk families and population screening of Ashkenazi Jewish individuals after discussion of test limitations and appropriate informed consent.55 The National Comprehensive Cancer Network recommends offering genetic susceptibility testing (after risk assessment and counseling) to individuals who meet the criteria for hereditary breast or ovarian cancer or both.56
The American Society of Clinical Oncology recommends that genetic testing be offered when:
- An individual has a personal or family history that suggests a genetic cancer susceptibility.
- The test can be adequately interpreted and its results will influence diagnosis or management of the patient or family members at risk for hereditary cancer.57
The American College of Obstetricians and Gynecologists Committee Opinion on breast and ovarian cancer screening, written in 2000, recommends offering BRCA mutation testing to families in which multiple family members have had breast or ovarian cancer or in which a BRCA mutation has been found.58
