Expanded genetic testing of BRCA mutations has led to identification of more reproductive-aged women who test positive for the mutation which might impact attitudes and decisions about relationships, childbearing and the use of preimplantation genetic diagnosis (PGD) and prenatal diagnosis (PND). A cross-sectional survey was administered to 1081 self-reported BRCA carriers to investigate how knowledge of BRCA status influences these issues. The mean age at BRCA test disclosure was 44 years and 36 % reported a personal history of cancer. Of 163 women who were unpartnered, 21.5 % felt more pressure to get married. Of 284 women whose families were not complete, 41 % reported that carrier status impacted their decision to have biological children. Women with a history of cancer were more likely to report that knowledge of BRCA+ status impacted their decision to have a child (OR 1.8, 95 % CI 1-3.2). Fifty-nine percent thought PGD should be offered to mutation carriers and 55.5 % thought PND should be offered. In conclusion, knowledge of BRCA status impacts attitudes regarding relationships and childbearing, and most carriers believe that PGD and PND should be offered to other carriers. This study suggests that BRCA carriers desire and would benefit from reproductive counseling after test disclosure.
对BRCA突变进行更广泛的基因检测,已使更多处于生育年龄的女性被鉴定出携带该突变,这可能会影响她们在人际关系、生育以及使用植入前基因诊断(PGD)和产前诊断(PND)方面的态度和决定。对1081名自我报告的BRCA携带者进行了一项横断面调查,以研究BRCA状态的知晓情况如何影响这些问题。BRCA检测结果披露时的平均年龄为44岁,36%的人报告有个人癌症病史。在163名单身女性中,21.5%感到结婚压力更大。在284名子女不全的女性中,41%报告携带者状态影响了她们生育亲生孩子的决定。有癌症病史的女性更有可能报告BRCA阳性状态的知晓情况影响了她们生育孩子的决定(比值比1.8,95%置信区间1 - 3.2)。59% 的人认为应该为突变携带者提供PGD,55.5%的人认为应该提供PND。总之,BRCA状态的知晓情况会影响人际关系和生育方面的态度,大多数携带者认为应该为其他携带者提供PGD和PND。这项研究表明,BRCA携带者在检测结果披露后渴望并将从生殖咨询中受益。
