[Chinese Protocol of Diagnosis and Treatment of Colorectal Cancer (2020 edition)].

Colorectal cancer (CRC) is one of the most common malignant tumors in China. In recent years, the incidence and mortality of CRC in China have been on the rise. According to the China cancer statistics report in 2018, the incidence and mortality of CRC in China ranked the third and fifth among all malignant tumors, with 376,000 new cases and 191,000 deaths. China has become the country with the highest number of new cases and deaths of CRC every year in the world, which seriously threatens the health of Chinese residents. In 2010, the National Ministry of Health organized colorectal cancer expertise of the Chinese Medical Association to write the Chinese Protocol of Diagnosis and Treatment of Colorectal Cancer (2010 edition) and publish it publicly. Since 2010, the National Health and Family Planning Commission has organized experts to revise the protocol in 2015 and 2017, while the National Health Commission revised it in 2020. The revised part of Chinese Protocol of Diagnosis and Treatment of Colorectal Cancer (2020 edition) involves new progress in the field of imaging examination, pathological evaluation, surgery, chemotherapy and radiotherapy. The 2020 edition of the protocol not only referred to the contents of the international guidelines, but also combined with the specific national conditions and clinical practice in China, and also included many evidence-based clinical data in China recently. The 2020 edition of the protocol would further promote the standardization of diagnosis and treatment of CRC in China, improve the survival and prognosis of patients, and benefit millions of CRC patients and their families.结直肠癌是我国常见的恶性肿瘤之一。近年来，我国结直肠癌发病率和死亡率均保持上升趋势。2018中国癌症统计报告显示，我国结直肠癌发病率和死亡率在全部恶性肿瘤中分别位居第3和第5位，其中新发病例37.6万例，死亡病例19.1万例。中国已成为全球结直肠癌每年新发病例数和死亡病例数最多的国家，结直肠癌严重影响和威胁我国居民身体健康。2010年，原国家卫生部委托中华医学会肿瘤学分会组织结直肠癌领域专家撰写并颁布了《结直肠癌临床诊疗规范（2010年版）》（简称《规范》）。《规范》的发布对我国结直肠癌诊疗意义重大，影响深远。近些年，随着对该《规范》应用的普及和理解的深入，原国家卫生和计划生育委员会于2015年、2017年，国家卫生健康委员会于2020年先后组织专家对《规范》进行了3次修订，内容涉及结直肠癌的影像学检查、病理学评估，外科治疗、内科治疗和放疗等多学科综合治疗手段等方面。2020年版《规范》既参考了国际指南的更新内容，更结合了中国的具体国情和临床实践，同时囊括了近些年来我国结直肠领域的重要进展和循证医学证据。2020年版《规范》将会进一步推动我国结直肠癌整体诊疗水平的进步，改善患者的生存和预后，造福结直肠癌患者及其家庭。.
