近一半的BRCA1/2携带者接受了降低风险的乳腺切除术 (RRM),自2008年以来,乳腺切除的数量一直在增加. 与BRCA2携带者相比,BRCA1携带者选择RRM的频率更高,年龄更小,术后乳腺癌发病率较低.
科学领域:
- 在瘤学瘤学.
- 遗传学 是一个遗传学.
- 预防医学 预防医学
背景情况:
- 降低风险的乳房切除术 (RRM) 是对BRCA1或BRCA2 (BRCA1/2) 致病性生殖系变异的个体的关键选择.
- 了解RRM吸收趋势对于个性化癌症预防策略至关重要.
研究的目的:
- 调查和比较2008年至2021年挪威BRCA1/2载体中RRM吸收率.
- 分析RRM吸收的时间趋势和手术后乳腺癌 (BC) 的发生率.
主要方法:
- 在奥斯陆大学医院 (2008-2021) 测试的1237个BRCA1/2载体的回顾性研究.
- 关于RRM,基因测试 (GT) 和随后的BC诊断的数据从国家注册表中收集.
- 对RRM吸收进行了基因,GT年龄和测试时间段的分析.
主要成果:
- 48.8%的BRCA1/2携带者选择了RRM,BRCA1 (54.5%) 与BRCA2 (42.0%) 携带者的吸收率更高.
- 2015/2016年接受测试的女性接受RRM的可能性是2008/2009年接受测试的女性的2.6倍.
- 只有0.3%的RRM后患者患有乳腺癌.
结论:
- 自2008年以来,BRCA1/2携带者中RRM的吸收率有所增加.
- 与BRCA1携带者相比,BRCA1携带者表现出较高的RRM吸收率,手术时较早的年龄,与BRCA2携带者相比,GT到RRM的时间较短.
- RRM与随后的乳腺癌发病率较低有关.

When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

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.
