Studies on the bio-markers of esophageal cancer

Abstract

食管癌是最常见的肿瘤之一,在全世界许多国家都是一种主要的肿瘤致死因素。目前对食管癌的确诊方法可分为:早期诊断和临床诊断两大类。临床诊断即上消化道造影及内镜检查,早期诊断指在出现症状前的诊断。目前食管癌早期诊断的方法主要还是食管拉网﹑内腔镜活体染色,但是其灵敏度和特异性都不是很理想。比较临床上对食管癌早期诊断的几种方法,分子生物学诊断技术中的肿瘤标记物检测是一种比较便捷、灵敏、特异的手段。; 肿瘤标记物是指那些能够反映恶性肿瘤细胞已经发展到那个阶段的能被检测到的特征性生物活性物质。狭义的肿瘤标记物指的是由恶性肿瘤细胞合成﹑分泌并释放入血液和/或体液中的生物活性物质,包括酶﹑激素﹑蛋白质﹑代谢产...EC (esophageal cancer) is one of the most common tumors ,It is a major element of tumor causing death in many countries .There are two methods of the diagnosis for EC, which includes the clinical diagnosis and the diagnosis at early stage.
