概括
定量咨询改善了对乳腺癌风险的认识,但没有影响 kontralateral 预防性乳房切除术 (CPM) 的决定. 这项研究强调了需要更好的工具来将风险理解转化为乳腺癌患者的手术选择.
科学领域:
- 在瘤学瘤学.
- 遗传学 遗传学是一种遗传学.
- 决策科学 决策科学 决策科学
背景情况:
- 越来越多的生殖基因检测率可能会影响新诊断的乳腺癌患者对逆向预防性乳房切除术 (CPM) 的决定.
- 准确的风险评估对于乳腺癌管理中的知情决策至关重要.
研究的目的:
- 量化个性化逆侧乳腺癌 (CBC) 风险咨询工具的影响,包括基因检测结果.
- 评估基因检测信息如何影响患者对CBC风险的理解以及随后的外科决定.
主要方法:
- 一项随机临床试验,涉及单边乳腺癌患者接受遗传咨询和手术.
- 参与者被随机分配到接受定量咨询,使用视觉决策支持工具与个性化CBC风险估计或标准咨询.
- 同主终点包括CBC风险知识和接受CPM的倾向,在咨询前后进行评估. 第二次终点是CPM率.
主要成果:
- 与接受标准咨询的患者相比,接受定量咨询的患者表现出更准确的CBC风险估计报告.
- 尽管风险知识有所提高,但辅导类型并没有显著影响风险感知,自我报告的CPM倾向或实际的CPM率.
- 这项研究包括346名患者,人口统计数据表明不同种族群体的代表性,并且有显著的百分比与一级亲属患有乳腺癌.
结论:
- 定量咨询可以提高患者对其计算的CBC风险的理解.
- 更好的风险知识本身并没有转化为CPM相关决策的变化.
- 开发的CBC风险评估工具是公开可用的,用于在手术前的讨论中帮助共享决策.

9.3K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
