概括

在巴雷特食道 (BE) 中异常的p53表达表明进展到高级瘤的风险更高. 然而,其低于最佳的诊断性能限制了对风险分层的广泛临床使用.

科学领域:

胃肠病学胃肠病学
在瘤学瘤学.
分子病理学分子病理学

背景情况:

巴雷特食道 (Barrett's esophagus,BE) 携带着进展到高度发育不良 (HGD) 和食道腺癌 (EAC) 的风险.
p53免疫组织化学 (IHC) 被探索为一种工具,用于BE的风险分层,但结果是矛盾的.

研究的目的:

系统地审查和元分析p53 IHC在预测BE患者HGD/EAC进展方面的表现.
评估与异常p53表达相关的诊断试验特征和风险比.

主要方法:

在多个数据库中系统地搜索BE活检中异常p53的研究.
使用随机效应模型进行元分析,以计算p53测试特征和进展风险比率 (RR).

主要成果:

在20%的BE患者中发现了异常的p53表达.
异常p53患者的HGD/EAC进展风险显著增加 (队列中的RR10.2,病例对照研究中的RR3.3).
对进展的敏感性和特异性因基线组织学而异,总体诊断准确度低于最佳.

结论:

异常的p53表达与BE监测中的进展风险增加有关.
p53 IHC的低最佳诊断特征阻碍了其广泛的临床采用.
需要使用标准化协议进行进一步的前性研究,以评估p53引导监测的有效性.

Barrett Esophagus-I: Introduction

Barrett Esophagus-I: Introduction

Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more...

Barrett Esophagus-II: Clinical Manifestations and Management

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...
