摘要结直肠癌是常见的恶性肿瘤之一，在我国的发病率仍呈上升趋势。通过筛查发现结直肠腺瘤或早期结直肠癌是降低结直肠癌发病率和死亡率的前提和关键。随着结直肠肿瘤无创诊断生物标志物的临床应用不断增多，以及相关研究证据的不断积累，国家消化系统疾病临床医学研究中心牵头，依托消化健康全国重点实验室，联合中国医师协会消化医师分会，组织我国消化内外科、消化内镜和肿瘤领域专家共同制定了本共识，以期为我国结直肠肿瘤无创诊断生物标志物的临床应用提供指导和参考。

abstractsColorectal cancer is one of the common malignant tumors with a rising incidence in China. Screening colorectal adenomas or early colorectal cancer is the prerequisite and key to reduce the incidence and mortality of colorectal cancer. In recent years, with the increasing application of noninvasive diagnostic biomarkers for colorectal neoplasms and accumulating evidence of relevant research, led by National Clinical Research Center for Digestive Diseases, supported by National Key Laboratory of Digestive Health, in conjunction with Gastroenterologist and Hepatologist Branch of Chinese Medical Doctor Association, multidisciplinary experts including gastroenterology, general surgery, digestive endoscopy and oncology jointly developed this consensus to provide guidance for the clinical application of noninvasive diagnostic biomarkers for colorectal neoplasms in China.
