PURPOSE/OBJECTIVES: To explore the decision-making process of women with a BRCA1 or BRCA2 gene mutation who have chosen to undergo prophylactic mastectomy.
Cross-sectional, qualitative, descriptive design.
Participants were recruited from an outpatient cancer prevention center in the oncology and medical genetics departments of a large university-affiliated hospital in Montreal, Quebec, Canada.
10 women carrying a BRCA1 or BRCA2 mutation; 8 previously had had a prophylactic mastectomy and 2 were scheduled for surgery at the time of study.
Semistructured, in-depth interviews were conducted. Field notes were written and audiotapes were transcribed verbatim. The textual data were coded and analyzed.
Decision-making process for prophylactic mastectomy.
Two broad findings emerged. First, several intrapersonal and contextual factors interacted throughout the process to move women either closer to choosing a prophylactic mastectomy or further from the decision. Second, all women reported experiencing a "pivotal point," an emotionally charged event when the decision to have a prophylactic mastectomy became definitive. Pivotal points for patients included either receiving a positive result for a genetic mutation or a breast cancer diagnosis for herself or a family member in the context of positive mutation status.
Decision making about prophylactic mastectomy was an affective and intuitive process incorporating contexts and their relations rather than a rational, straight-forward process of weighing pros and cons.
Supportive interventions for women in this population should explicitly address the individual and the inter-relationships of contextual factors that shape decision making about prophylactic mastectomy while recognizing important affective components involved.
目的/目标:探讨携带BRCA1或BRCA2基因突变且选择接受预防性乳房切除术的女性的决策过程。
横断面、定性、描述性设计。
研究对象从加拿大魁北克省蒙特利尔市一所大型大学附属医院的肿瘤学和医学遗传学部门的门诊癌症预防中心招募。
10名携带BRCA1或BRCA2基因突变的女性;其中8名之前已接受预防性乳房切除术,2名在研究时计划进行手术。
进行半结构化的深入访谈。记录现场笔记并逐字转录录音带。对文本数据进行编码和分析。
预防性乳房切除术的决策过程。
出现了两个主要结果。第一,在整个过程中,几个个人因素和背景因素相互作用,使女性要么更倾向于选择预防性乳房切除术,要么远离该决策。第二,所有女性都报告经历了一个“关键点”,即一个情绪激动的事件,此时进行预防性乳房切除术的决定变得确定。对患者来说,关键点包括在基因突变呈阳性的情况下,自己或家庭成员的基因突变检测结果呈阳性或被诊断出患有乳腺癌。
关于预防性乳房切除术的决策是一个包含各种背景及其关系的情感和直观过程,而不是一个权衡利弊的理性、直接的过程。
针对这一人群中的女性的支持性干预措施应明确解决影响预防性乳房切除术决策的个体因素和背景因素之间的相互关系,同时认识到其中涉及的重要情感因素。
