概括
良性乳腺疾病增加乳腺癌的风险. 多基因风险得分进一步分层化了这一风险,较高的得分表明患乳腺癌的几率明显增加.
科学领域:
- 在瘤学瘤学.
- 遗传学 遗传学 是一个
- 流行病学 流行病学
背景情况:
- 大多数乳腺活检都是良性的,但会增加1.5至4倍的乳腺癌风险.
- 除了非典型的增多外,对良性乳腺疾病患者的乳腺癌风险评估存在有限的因素.
- 本研究研究了313个单核酸变异多基因风险评分 (PRS) 对风险分层的有用性.
研究的目的:
- 确定313个单核酸变异多基因风险评分 (PRS) 是否可以对良性乳腺疾病患者的乳腺癌风险进行分层.
- 评估良性乳腺疾病史和PRS对乳腺癌风险的综合影响.
- 评估与乳腺癌风险相关的良性乳腺疾病和PRS之间的相互作用和调解.
主要方法:
- 来自乳腺癌协会联盟的5项病例对照研究 (6706例,8488例对照) 的数据汇总.
- 逻辑回归用于通过良性乳腺疾病史和PRS层来估计乳腺癌风险.
- 评估了良性乳腺疾病和PRS之间的相互作用和调解.
主要成果:
- 良性乳腺疾病史与乳腺癌风险增加1.48倍相关 (P < .001).
- 在良性乳腺疾病史 (P 相互作用 = .48) 独立的情况下,PRS增加了乳腺癌风险.
- 患有良性乳腺疾病和高PRS (最高三位数) 的女性患乳腺癌的几率增加了超过2倍 (OR = 2.73);最低三位数的女性患乳腺癌的风险降低了 (OR = 0.79).
- 与中位数PRS和没有良性乳腺疾病的女性相比,患有良性乳腺疾病和PRS的女性的乳腺癌几率增加了3.7倍.
结论:
- 患有良性乳腺疾病的女性患乳腺癌的风险较高,并且随着多基因风险得分较高而逐渐增加.
- 结合良性乳腺疾病状态和多基因风险评分可能会增加乳腺癌风险分层.
- 这些发现支持使用PRS来对患有良性乳腺疾病的妇女进行个性化风险评估.

Genome-wide Association Studies-GWAS
13.1K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
