概括
多基因风险评分 (PRSs) 在识别患前列腺癌风险较高的男性方面表现出适度的能力. 然而,目前的PRS并不能有效地区分疾病的侵略性和惰性形式.
科学领域:
- 遗传学 是一个遗传学.
- 在瘤学瘤学.
- 流行病学 流行病学
背景情况:
- 多基因风险评分 (PRS) 是开发用于预测前列腺癌风险的遗传工具.
- 评估现有PRS的实际性能对于临床应用至关重要.
研究的目的:
- 为了比较16个PRS在识别患前列腺癌风险的男性方面的表现.
- 评估高性能PRS在分辨侵袭性前列腺癌方面的能力.
主要方法:
- 一个用16个已发表的PRS应用于密歇根基因组学倡议 (MGI) 患者的病例控制研究.
- 病例数据与密歇根泌尿外科改善协作 (MUSIC) 注册表进行了匹配,以获得临床和病理细节.
- 性能被评估使用面积在共变量调整的接收器操作特征曲线 (aAUC) 下和疾病攻击性的后勤回归.
主要成果:
- 对于前列腺癌风险的16个PRS的预测性表现 (aAUC) 从0.51到0.67.
- 根据活检数据,没有发现PRS和前列腺癌攻击性之间的显著关联.
- 这项研究包括18050名患者:2740例前列腺癌病例和15310例对照.
结论:
- 前列腺癌PRS在识别患有该疾病风险增加的个体方面表现出适度的有效性.
- 目前的PRS在区分惰性和侵略性前列腺癌方面存在局限性,需要进一步改进.

Genome-wide Association Studies-GWAS
13.3K
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.

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
125
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...
