The increasing demand for genetic assessment for familial breast cancer has necessitated the development of cancer genetics services. However, little is known about the factors motivating the client population likely to approach these services. A cross sectional questionnaire survey of 1000 women with a family history of breast cancer was conducted to identify self-reported reasons for attending a familial breast cancer clinic and possible differences in the characteristics of women who were attending for diverse reasons. Before attendance at clinic, 833 women completed a baseline questionnaire (83% response rate). Women who gave personal risk (n=188), awareness of a family history (n=120), risk to family members (n=84), reassurance (n=69), genetic testing (n=65), breast screening (n=46), or prevention (n=39) as their main reason for attending were compared on demographic and medical variables, and on psychological variables including general anxiety, cancer worry, perceived risk, and attitudes towards prophylactic surgery and genetic testing. Important differences in the psychological characteristics of these groups were found, which were unrelated to reported family history. In particular, women who primarily wanted genetic testing felt extremely vulnerable to developing breast cancer, were more likely to be considering prophylactic surgery, and perceived fewer limitations of testing. Those who primarily wanted reassurance were highly anxious about the disease. We recommend that cancer genetics services take into consideration the informational and psychological needs and concerns of their client group.
对家族性乳腺癌基因评估的需求不断增加,使得癌症基因检测服务的发展成为必要。然而,对于可能寻求这些服务的客户群体的动机因素,我们却知之甚少。我们对1000名有乳腺癌家族史的女性进行了横断面问卷调查,以确定她们自我报告的前往家族性乳腺癌诊所就诊的原因,以及因不同原因就诊的女性在特征上可能存在的差异。在就诊前,833名女性完成了一份基线调查问卷(回复率为83%)。将以个人风险(n = 188)、家族史认知(n = 120)、对家庭成员的风险(n = 84)、安心(n = 69)、基因检测(n = 65)、乳房筛查(n = 46)或预防(n = 39)作为主要就诊原因的女性,在人口统计学和医学变量以及心理变量(包括一般焦虑、癌症担忧、感知风险以及对预防性手术和基因检测的态度)方面进行了比较。结果发现这些群体在心理特征上存在重要差异,且这些差异与所报告的家族史无关。特别是,主要希望进行基因检测的女性认为自己极易患乳腺癌,更有可能考虑预防性手术,并且认为检测的局限性较小。那些主要希望获得安心的女性对该疾病高度焦虑。我们建议癌症基因检测服务机构考虑其客户群体的信息需求和心理需求及担忧。
