BRCA1/2 testing is not recommended for children, as risk reduction measures and screening are not generally recommended before 25 years old (YO). Little is known about the prevalence and predictors of parent communication to offspring and how offspring respond to this communication.
Semi-structured interviews were conducted with parents who had BRCA1/2 testing and at least 1 child <25 YO. Logistic regressions were utilized to evaluate associations with communication. Framework analysis was utilized to analyze open-ended responses.
A total of 253 parents completed interviews (61% response rate), reporting on 505 offspring. Twenty-nine percent of parents were BRCA1/2 mutation carriers. Three hundred thirty-four (66%) offspring learned of their parent's test result. Older offspring age (P ≤ .01), offspring gender (female, P = .05), parents' negative test result (P = .03), and parents' education (high school only, P = .02) were associated with communication to offspring. The most frequently reported initial offspring responses were neutral (41%) or relief (28%). Thirteen percent of offspring were reported to experience concern or distress (11%) in response to parental communication of their test results. Distress was more frequently perceived among offspring learning of their parent's BRCA1/2 positive or variant of uncertain significance result.
Many parents communicate their BRCA1/2 test results to young offspring. Parents' perceptions of offspring responses appear to vary by offspring age and parent test result. A better understanding of how young offspring respond to information about hereditary risk for adult cancer could provide opportunities to optimize adaptive psychosocial responses to risk information and performance of health behaviors, in adolescence and throughout an at-risk life span.
BRCA1/2 检测不建议用于儿童,因为一般不建议 25 岁以下(YO)采取降低风险措施和筛查。对于父母与子女的沟通情况及其子女的反应,人们知之甚少。
对 BRCA1/2 检测且至少有 1 名 25 岁以下子女的父母进行半结构式访谈。采用逻辑回归评估与沟通相关的关联。采用框架分析对开放式回答进行分析。
共有 253 名父母完成了访谈(61%的回复率),报告了 505 名子女的情况。29%的父母为 BRCA1/2 突变携带者。334 名(66%)子女了解其父母的检测结果。年长的子女年龄(P ≤.01)、子女性别(女性,P =.05)、父母阴性检测结果(P =.03)和父母的教育程度(仅高中,P =.02)与子女沟通有关。报告的子女最初反应最常见的是中性(41%)或宽慰(28%)。有 13%的子女在得知父母的检测结果时表示担忧或不安(11%)。在得知父母 BRCA1/2 阳性或意义不明的变异结果时,子女更有可能感到担忧。
许多父母会向年幼的子女传达他们的 BRCA1/2 检测结果。父母对子女反应的看法似乎因子女年龄和父母的检测结果而异。更好地了解年轻子女对有关成人癌症遗传风险的信息的反应,可以为优化对风险信息和健康行为的适应型心理社会反应提供机会,从而在青少年时期和整个高危生命期。
