[Expert consensus on the early diagnosis and treatment of colorectal cancer in China (2023 edition)].

Colorectal cancer (CRC) has been a common malignant tumor in China. Through the great effort in cancer prevention and treatment, the 5-year survival rate of patients with CRC in China has been largely improved. However, insufficient early diagnosis and treatment have seriously impeded the prognosis of Chinese CRC patients. The Early Diagnosis and Treatment Group of the Chinese Medical Association, Oncology Branch organized experts in the area of CRC to write the Expert Consensus on the Early Diagnosis and Treatment of Colorectal Cancer in China and issued it publicly (2020 edition). The 2020 edition of expert consensus has been meaningful to the early diagnosis and standardized treatment of CRC. Based on the prior edition, the Early Diagnosis and Treatment Group of the Chinese Medical Association, Oncology Branch revise the consensus focused on the early screening and diagnosis protocols for colorectal cancer, endoscopic/surgical management of early colorectal tumor, as well as adjuvant treatment and remedial measures and follow-up monitoring protocols. The 2023 edition of the consensus not only synthesized the latest evidence from China and combined it with the specific national condition and clinical practice, but also referred to the international guidelines. This 2023 edition consensus, developed for clinicians working on the screening, early diagnosis and treatment for CRC, would further promote the standardization and advances in the diagnosis and treatment of CRC at the early stage in China, and improve the survival and prognosis of CRC.结直肠癌是我国常见恶性肿瘤。通过防治结合，我国结直肠癌患者的5年生存率已大幅提高。对照国际先进经验，较低的早期诊断及早期治疗率成为限制我国结直肠癌患者预后进一步提高的瓶颈。2020年，中华医学会肿瘤学分会早诊早治学组组织结直肠癌领域专家撰写并颁布了《中国结直肠癌早诊早治专家共识》，该共识发布对我国结直肠癌早期诊断及规范化治疗意义重大。在2020版基础上，中华医学会肿瘤学分会早诊早治学组就结直肠癌的早期筛查及诊断方案、早期结直肠肿瘤的内镜和外科处理以及辅助治疗与补救措施和随访监测方案等内容进行修订，以国内外结直肠癌早期诊疗领域的临床研究进展为基础，结合中国的国情和临床实践，同时又参考了国际指南的更新内容，达成2023年版专家共识供参考。2023版专家共识将会进一步规范和优化我国结直肠癌早期诊疗，改善患者生存和预后。.
