Indications for genetic testing for inherited cancer syndromes are expanding both in the academic and the community setting. However, only a fraction of individuals who are candidates for testing pursue this option. Therefore, it is important to understand those factors that impact the uptake of genetic testing in individuals affected and unaffected with cancer. A successful translation of genomic risk stratification into clinical care will require that providers of this information are aware of the attitudes, perceived risks and benefits, and concerns of individuals who will be considering testing. The purpose of this study was to assess beliefs, attitudes and preferences for genetic risk information, by personal characteristics of women affected and unaffected by breast cancer enrolled in the Breast Cancer Family Registry Cohort. Data for this analysis came from eight survey questions, which asked participants (N = 9,048, 100% female) about their opinions regarding genetic information. Women reported that conveying the accuracy of the test was important and were interested in information related to personal level of risk, finding out about diseases that could be treated, and information that could be helpful to their families. Young women were most interested in how their own health needs might be impacted by genetic test results, while older women were more interested in how genetic information would benefit other members of the family. Interest in how the genetic test was performed was highest among Asian and Hispanic women. Women affected with breast cancer were more likely to report feeling sad about possibly passing down a breast cancer gene, while unaffected women were more uncertain about their future risk of cancer. The variety of informational needs identified has implications for how genetic counselors can tailor communication to individuals considering genetic testing.
遗传性癌症综合征的基因检测适应证在学术和社区环境中都在不断扩大。然而,只有一部分有资格接受检测的人会选择进行检测。因此,了解影响癌症患者和未患癌者接受基因检测的因素非常重要。要成功地将基因组风险分层转化为临床护理,就需要提供这些信息的医务人员了解考虑进行检测的个体的态度、感知的风险和益处以及关注的问题。本研究旨在评估乳腺癌家族登记队列中受乳腺癌和未受乳腺癌影响的女性的个人特征对遗传风险信息的信念、态度和偏好。这项分析的数据来自于八个调查问题,这些问题要求参与者(N=9048,100%为女性)对他们对遗传信息的看法进行回答。女性报告说,传达检测的准确性很重要,她们对与个人风险水平相关的信息、与可治疗疾病相关的信息以及可能对其家庭有帮助的信息感兴趣。年轻女性最关心遗传测试结果如何影响自己的健康需求,而年长女性则更关心遗传信息将如何使家庭的其他成员受益。对如何进行基因检测最感兴趣的是亚裔和西班牙裔女性。患有乳腺癌的女性更有可能因可能遗传乳腺癌基因而感到悲伤,而未患癌的女性则对自己未来的癌症风险更加不确定。确定的各种信息需求对遗传咨询师如何针对考虑进行基因检测的个体进行沟通具有重要意义。
