Genetic testing for the breast cancer susceptibility genes, BRCA1 and BRCA2, has been available for over a decade. Positive test results carry significant medical, psychological, and social implications. Knowledge of the public's awareness concerning BRCA testing, and perceived benefits and barriers to testing can help refine educational programs and identify subgroups needing additional support. Patients and their acquaintances with a breast complaint attending a surgical clinic or private office were asked to complete a questionnaire about their knowledge of breast cancer genes and their desire to be tested. Demographic information collected included ethnicity, education background, age, income, and personal and family history of breast cancer, knowledge of BRCA genes and testing, and their willingness to participate in genetic counseling. A total of 222 people completed the questionnaire that showed the majority of subjects in southeast Georgia believe breast cancer is inherited 26-50% of the time. Caucasians and those with advanced degrees are the most informed regarding awareness of BRCA genes (p < 0.05); the least informed groups include African Americans and those with no more than a college education. Participants with a family history of breast cancer were significantly more likely to know that genes had been identified that indicate an increased risk of breast cancer (p < 0.05). A history of breast cancer did not impact the degree of awareness (p > 0.05). Subjects aware of genetic testing are more willing to utilize counseling (p < 0.05). Perceptions of breast cancer inheritance, awareness of susceptibility genes, and availability of testing and counseling are not uniform among all population subgroups. In southeast Georgia, educational efforts should focus on the less educated and minority groups.
乳腺癌易感基因 BRCA1 和 BRCA2 的基因检测已经有十多年的历史了。阳性检测结果具有重要的医学、心理和社会意义。了解公众对 BRCA 检测的认识,以及对检测的益处和障碍的看法,可以帮助完善教育计划,并确定需要额外支持的亚组。在外科诊所或私人诊所就诊的有乳房问题的患者及其熟人被要求填写一份关于他们对乳腺癌基因的了解以及他们进行检测的愿望的问卷。收集的人口统计信息包括种族、教育背景、年龄、收入以及个人和家族的乳腺癌史、对 BRCA 基因和检测的了解,以及他们是否愿意参加遗传咨询。共有 222 人完成了问卷,调查结果显示佐治亚州东南部的大多数人认为乳腺癌有 26-50%的几率是遗传的。白人和拥有高等学历的人对 BRCA 基因的认识程度最高(p < 0.05);最不了解的群体包括非裔美国人和受过大学以下教育的人。有乳腺癌家族史的参与者更有可能知道已经确定了一些基因,这些基因表明乳腺癌的风险增加(p < 0.05)。乳腺癌病史并不影响认识程度(p > 0.05)。了解基因检测的人更愿意接受咨询(p < 0.05)。对乳腺癌遗传的看法、对易感基因的认识、检测和咨询的可用性在所有人群亚组中并不统一。在佐治亚州东南部,教育工作应侧重于教育程度较低和少数族裔群体。
