Abstract：
The liver is the most common anatomical site for hematogenous metastases of colorectal cancer, and colorectal liver metastasis is one of the most difficult and challenging situations in the treatment of colorectal cancer. In order to improve the diagnosis and comprehensive treatment in China, the Guidelines have been edited and revised for several times since 2008, including the overall evaluation, personalized treatment goals and comprehensive treatments, to prevent the occurrence of liver metastases, improve the resection rate of liver metastases and survival. The revised Guideline version 2020 includes the diagnosis and follow-up, prevention, multidisciplinary team (MDT), surgery and local ablative treatment, neoadjuvant and adjuvant therapy, and comprehensive treatment, with state-of-the-art experience and findings, detailed content, and strong operability.
肝脏是结直肠癌血行转移最主要的靶器官，结直肠癌肝转移是结直肠癌治疗的重点和难点之一。为了提高我国结直肠癌肝转移的诊断和综合治疗水平，自2008年开始编写《中国结直肠癌肝转移诊断和综合治疗指南》并后续进行了多次修订，以期指导对结直肠癌肝转移患者进行全面评估，个性化地制定治疗目标，开展相应的综合治疗，达到预防结直肠癌肝转移的发生、提高肝转移灶手术切除率和改善5年生存率的目的。本次修订后的2020版《指南》包括结直肠癌肝转移的诊断和随访、预防、MDT作用、手术治疗和局部毁损治疗、可达到\"无疾病证据\"状态结直肠癌肝转移的新辅助和辅助治疗、无法达到\"无疾病证据\"状态结直肠癌肝转移的综合治疗等六部分，汇集总结国内外该领域的先进经验和最新成果，内容详尽，可操作性强。.
