概括
遗传风险得分在预测不同祖先群体的前列腺癌活检中表现出不同的有效性. 虽然它们增加了检测能力,但欧洲后裔的预测能力比非洲祖先群体更强大.
科学领域:
- 遗传学 是一个遗传学.
- 在瘤学瘤学.
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
背景情况:
- 在不同的祖先群体中,前列腺癌的风险有很大差异.
- 遗传风险评分 (GRS) 在各种祖先群体中预测前列腺癌诊断的实用性仍在调查中.
研究的目的:
- 评估多基因危险评分 (PHS290) 与第一次活检时前列腺癌诊断风险之间的关联.
- 评估基因风险预测模型在不同祖先群体,特别是非洲和欧洲后裔的相对性能.
主要方法:
- 在一个由36717名男性退伍军人组成的队列上进行了横截面的回顾分析,其中包括10297名非洲血统的退伍军人.
- 这项研究检查了PHS290遗传风险得分与前列腺第一次活检呈阳性的可能性之间的关联.
- 统计分析使用双面测试来确定显著性.
主要成果:
- 较高的遗传风险与阳性第一次前列腺活检率的增加显著相关 (34%在低风险组与58%在高风险组;P<.001).
- 在非洲血统的男性中,更高的遗传风险与前列腺癌检测率的增加相关 (OR = 2.18),但与欧洲血统的男性相比,这种关联不那么明显 (OR = 3.89).
结论:
- 遗传风险分层显示出个性化前列腺癌活检决策的潜力.
- 需要进一步的研究来完善遗传风险预测模型,并确保在多样化的祖先群体中实现公平的表现.

Cancer Prevention
6.2K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Genome-wide Association Studies-GWAS
13.4K
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.
