骨髓性乳腺癌是一种罕见的乳腺癌亚型. 它与BRCA1突变的强烈关联表明它应该成为基因测试的标准,以改善早期检测和预防.
科学领域:
- 癌症学
- 遗传学
- 病理学
背景情况:
- 骨髓性乳腺癌 (MBC) 是一种罕见的侵袭性乳腺癌,占所有乳腺癌的0.2%~6%.
- 在患有三阴性乳腺癌和BRCA1突变的患者中,MBC更为普遍.
研究的目的:
- 在所有乳腺癌诊断中确定骨髓性乳腺癌的频率.
- 评估骨髓性乳腺癌与BRCA1突变之间的联系.
主要方法:
- 对报告乳腺癌组织学和BRCA1突变状态的研究进行系统审查.
- 在骨髓乳癌病例中分析BRCA1突变的比例,反之亦然.
主要成果:
- 在骨髓性乳腺癌中,BRCA1突变的患病率在3%至35. 3%之间.
- 骨髓性乳腺癌占所有BRCA1突变乳腺癌的8%~20%.
结论:
- 骨髓性乳腺癌与BRCA1突变之间存在显著的关联.
- 骨髓性乳腺癌应被视为BRCA1基因检测的标准,以加强对突变载体的查和预防策略.

Cancer-Critical Genes I: Proto-oncogenes
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.
