In 2005, the United States Preventive Services Task Force (USPSTF) released guidelines which outlined specific family history patterns associated with an increased risk for BRCA1/2 mutations, and recommended at-risk individuals be referred for genetic counseling and evaluation for BRCA testing. The purpose of this study was to assess the prevalence of individuals with a USPSTF increased-risk family history pattern, the frequency with which specific patterns were met, and resulting healthcare actions among women from the Henry Ford Health System.
As part of a study evaluating ovarian cancer risk perception and screening, 2,524 randomly selected participants completed a detailed interview (response rate 76%) from an initial eligible cohort of 16,720 women.
Approximately 6% of participants had a family history fulfilling one or more of the USPSTF patterns. Although 90% of these women had shared their family history with their provider, less than 20% had been referred for genetic counseling and only 8% had undergone genetic testing. Caucasian women with higher income and education levels were more likely to receive referrals. Among the 95 participants in the total study cohort who reported BRCA testing, 78% did not have a family history that met one of the USPSTF patterns.
These results suggest a higher prevalence of women with an increased-risk family history than originally predicted by the USPSTF, and lack of provider recognition and referral for genetic services.
Improvements in healthcare infrastructure and clinician education will be required to realize population level benefits from BRCA genetic counseling and testing.
2005 年,美国预防服务工作组(USPSTF)发布了指南,概述了与 BRCA1/2 突变风险增加相关的特定家族史模式,并建议将有风险的个体转介进行遗传咨询和 BRCA 检测评估。本研究的目的是评估亨利福特健康系统女性中具有 USPSTF 高风险家族史模式的个体的患病率、特定模式出现的频率以及由此产生的医疗保健行为。
作为评估卵巢癌风险认知和筛查的研究的一部分,从最初符合条件的 16720 名女性队列中,随机选择 2524 名参与者完成了详细的访谈(应答率为 76%)。
约 6%的参与者有符合 USPSTF 模式之一或更多的家族史。尽管 90%的女性曾与医生分享过家族史,但不到 20%的人被转介进行遗传咨询,只有 8%的人接受了基因检测。收入和教育水平较高的白人女性更有可能获得转介。在总研究队列中报告进行 BRCA 检测的 95 名参与者中,有 78%的人没有符合 USPSTF 模式之一的家族史。
这些结果表明,具有高风险家族史的女性比 USPSTF 最初预测的更为普遍,而且缺乏提供者对遗传服务的识别和转介。
需要改善医疗保健基础设施和临床医生教育,以从 BRCA 基因咨询和检测中实现人群水平的获益。
