Evidence StatementClinical Preventive Service RecommendationsU.S. Preventive Services Task Force RecommendationThe U.S. Preventive Services Task Force (USPSTF) recommends that women whose family history is associated with an increased risk of deleterious mutations in BRCA1 or BRCA2 genes be referred for genetic counseling and evaluation for BRCA testing.1Evidence Rating: B (Recommended/At Least Fair Evidence) The USPSTF found fair evidence that women with certain specific family history patterns (increased-risk family history) have an increased risk for developing breast or ovarian cancer associated with BRCA1 or BRCA2 mutations. The USPSTF determined that these women would benefit from genetic counseling that allows informed decision making about testing and further prophylactic treatment. This counseling should be done by suitably trained healthcare providers. There is fair evidence that prophylactic surgery significantly decreases breast and ovarian cancer incidence in women who test positive for deleterious BRCA1 or BRCA2 mutations, although there is insufficient evidence to determine other health-outcome benefits from intensive screening or preventive medication in such women.1
The Value of PreventionEconomic Burden of Condition/DiseaseThe direct medical care costs for breast cancer treatment were estimated to exceed $6 billion in 1996.8 The total economic burden of breast cancer would be much higher if breast cancer related mortality and morbidity costs were included in this figure. In 2004, for example, the overall cost of cancer (including direct and indirect cots) was estimated to be almost $190 billion9, and breast cancer could account for up to one-quarter of this total.10 A small proportion of the economic burden of breast cancer is attributable to genetically-related breast cancers.The risk of breast cancer increases with age.7 Population aging in the coming decades is expected to increase the number of breast cancer cases and the economic burden of the disease. Workplace Burden of Condition/DiseaseWomen aged 40 to 64 years accounted for 61% of in situ cases, 54% of invasive breast cancer cases, and 40% of breast cancer deaths in 2005.2 The breast cancer medical care costs, productivity losses, and mortality costs among working women in this group is substantial.Economic Benefit of Counseling, Testing and Preventive TreatmentThe recognition of BRCA mutations through testing allows for early intervention and treatment. This is important because women who receive early treatment generally have better outcomes. For example, in one research model, a 30-year-old BRCA1 and 2 positive woman could prolong her life by about 1 year by having bilateral oophorectomy, 3.4 years by having bilateral mastectomy, and 4.3 years by having both procedures instead of surveillance alone.11Estimated Cost of Counseling, Testing and Preventive TreatmentIn 2004, the private-sector cost of BRCA mutation testing averaged $53 per test; approximately 95% of all paid claims fell within the range of $12 to $201 per test.12 The cost of genetic counseling averaged $39 per session; approximately 95% of all paid claims fell within the range of $0 to $129 per session.12 The cost of a preventive mastectomy or oophorectomy varies by location and facility type.Cost-Effectiveness and/or Cost-Benefit Analysis of Counseling, Testing and Preventive TreatmentOne study, using modeling techniques, concluded that BRCA1 and BRCA2 testing is cost-effective only if women who screen positive proceed with prophylactic surgery.13 The model further suggested that, per life-year saved, combined surgery cost $20,717, mastectomy cost $29,970, and oophorectomy cost $72,780 (all figures in year 1995 dollars).13 Another study, which also used modeling techniques, concluded that for women who are positive for a BRCA1 or BRCA2 genetic mutation, prophylactic surgery at a young age significantly improves survival and is cost-effective in comparison to other interventions.14Condition / Disease Specific InformationEpidemiology of Condition/DiseaseBreast cancer is the most commonly diagnosed non-skin cancer and the second leading cause of cancer death among women in the United States.2 In 2005, 211,000 women are expected to be diagnosed with breast cancer and 40,000 women are expected to die as a result of breast cancer.2Condition/Disease Risk FactorsRisk factors for breast cancer (reported by the USPSTF) include:3
Preventive Intervention InformationPurpose of Counseling, Testing and Preventive TreatmentThe purpose of family history assessment, counseling, and BRCA mutation-testing is to identify women with certain specific family history patterns that are associated with an increased risk for deleterious mutations in the BRCA1 or BRCA2 gene and an increased risk of breast or ovarian cancer. With the assistance of genetic counseling, women at risk can make an informed decision on testing and treatment options.Benefits and Risks of Counseling, Testing and Preventive TreatmentThe USPSTF determined that women with certain specific family history patterns benefit from genetic counseling that allows informed decision making about testing and preventive treatment (e.g., removal of the breasts and/or ovaries).1 The USPSTF found fair evidence that prophylactic surgery significantly decreases the incidence of breast and ovarian cancer among women with a BRCA mutation. Thus, the potential benefits of referral and discussion of testing and prophylactic treatment for these women may be substantial. The inherent risk associated with preventive treatment and surgery, such as patient anxiety and medical errors, may be substantial for some individuals.The USPSTF concluded that for women whose family history is not associated with an increased risk of deleterious mutations, the harms of routine referral for counseling and testing outweigh the benefits.1 Initiation of Counseling, Testing and Preventive TreatmentPatients identified as high-risk through a clinician risk assessment should be referred for genetic counseling and, if appropriate, follow-up genetic mutation testing. The initiation, cessation, and frequency of counseling is left to the discretion of the clinician. A onetime BRCA test should be administered to at-risk patients who request testing. Preventive treatment including mastectomy and/or ophorectomy should be conducted, as medically necessary, at the discretion of the clinician.Note: The USPSTF realizes that clinical decisions about patients involve more complex considerations that the evidence alone; clinicians should always understand the evidence but individualize decision making to the specific patient and situation. Intervention Process: Counseling, Testing and Preventive TreatmentThe clinician should assess the patient's family history of breast cancer to determine the likelihood that the patient has a deleterious BRCA mutation.1 If the assessment is positive, the woman should be referred for genetic counseling to help determine if she wishes to have genetic testing. Women may require further counseling after test results are received. A positive test for a deleterious mutation may result in a decision to have the surgical removal of her breasts and/or ovaries. Coverage should include clinician time to evaluate family history for possible referral to a genetic counselor, counseling on the harms and benefits of genetic testing by a qualified practitioner, and preventive treatment (e.g., complete mastectomy with or without reconstructive surgery, ophorectomy).Treatment InformationHealth benefits should include provisions for diagnostic and treatment services.Strength of Evidence for the Clinical Preventive Service Breast Cancer (Screening)The level of evidence supporting the recommendations contained in this section is described below.Evidence-Based Research: Summary Plan DescriptionSummary Plan Description Language: Breast Cancer Genetic Risk Assessment and BRCA Mutation Testing (Counseling)Covered CounselingBeneficiaries determined to be at high risk for breast cancer based on the results of a clinician's risk assessment are eligible for genetic counseling.Initiation, Cessation, and IntervalCounseling is provided as medically indicated, and should be conducted at least once before and after genetic testing.Summary Plan Description Language: Breast Cancer Genetic Risk Assessment and BRCA Mutation Testing (Testing)Covered TestingBeneficiaries determined to be at high risk for breast cancer based on the results of a clinician's risk assessment are eligible for BRCA mutation testing.Initiation, Cessation, and IntervalBRCA mutation testing is covered once per lifetime.Summary Plan Description Language: Breast Cancer Genetic Risk Assessment and BRCA Mutation Testing (Preventive Treatment)Covered Preventive TreatmentBeneficiaries determined to be at high risk for breast cancer based on the results of a clinician's risk assessment or the results of BRCA mutation testing are eligible for preventive treatment, which may include any of the following:
