概括

使用β-防御素指数 (BDI) 的新型测试可以非侵入性地检测口腔状细胞癌 (OSCC). 这种具有成本效益的方法显示出高准确性,可能有助于早期诊断,特别是在资源有限的环境中.

科学领域:

生物化学生物化学
在瘤学瘤学.
生物标志物生物标志物

背景情况:

口腔状细胞癌 (OSCC) 诊断缺乏非侵入性,具有成本效益的测试.
人类β-防御素3 (hBD-3) 在早期的OSCC中过度表达,与hBD-2不同,这表明它是一个潜在的诊断标志物.

研究的目的:

在OSCC中验证hBD-3/hBD-2表达比的诊断潜力.
开发一种非侵入性生物标志物,即β-防御酶指数 (BDI),用于OSCC检测.

主要方法:

免疫光显微镜和流细胞计验证了hBD-3/hBD-2表达.
艾丽莎测量了非侵入性采集细胞中的hBD-3/hBD-2水平,以计算BDI.
多中心验证评估了BDI的敏感性和特异性.

主要成果:

在OSCC病变中证实了hBD-3/hBD-2表达二分法.
在一个多中心研究中,BDI表现出高灵敏度 (98.2%) 和特异性 (82.6%).
BDI可适应于临床微流体检测.

结论:

贝塔-防御因子指数 (BDI) 显示出作为OSCC的非侵入性诊断工具的希望.
BDI可以解决在资源较少的地区对可访问的口腔癌诊断的未满足需求.

关键词:

这是OSCCCC的OSCC.生物标志物生物标志物在 hBD-2 中使用.在 hBD-3 中使用.

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...
