大肠癌筛查方法的进展

Progress on the screening for colorectal cancer

大肠癌是我国最常见的消化道肿瘤之一,早期常无症状,一旦确诊多属中晚期。大肠癌筛查能够有效降低大肠癌相关发病率及死亡率,近年来随着分子生物学、医学影像学等技术的发展,筛查方法不断改进和创新。现有多种基于人群的大肠癌筛查方法,故本文对其筛查方法的研究进展进行概述,并展望未来发展趋势。

Colorectal cancer is one of the most common gastrointestinal cancer,early often asymptomatic, mostly advanced when once diagnosed. Colorectal cancer screening can reduce colorectal cancer-related morbidity and mortality. In recent years with the development of molecular biology,medical imaging and other techniques, the screening method has got continuous improvement and innovation. There are an extensive range of population- based colorectal cancer screening methods,this paper reviewed their research progress on screening methods,and future trends.
