[Development of guidelines and clinical practice for breast cancer].

In the past two decades, with the introduction of NCCN guidelines, the establishment of a standardized diagnosis and treatment system for breast cancer had begun. The Chinese version of the NCCN guidelines, which combines international standards and Chinese characteristics, was then developed to guide clinical practice. Since 2011, Chinese experts have entered St. Gallen International Expert Consensus Group, and to introduce the latest therapy concepts. On this basis, the Chinese Society of Clinical Oncology has developed guidelines for diagnosis and treatment in line with product accessibility and expert opinions to help clinicians choose the best treatment option. The latest Chinese Society of Clinical Oncology Breast Cancer Guideline will further contribute to the establishment of a standardized diagnosis and treatment system for breast cancer.近二十年来，以引入NCCN指南为契机，我国乳腺癌规范化诊疗体系开始建立。结合国际标准和中国特色的NCCN指南中文版出版，以指导临床实践。2011年起，中国专家进入St. Gallen国际专家共识团，参与国际共识和指南的讨论，引入最新的合作机制和治疗理念。在此基础上，中国临床肿瘤学会结合产品可及性和专家意见制定了符合中国国情的乳腺癌诊疗指南，帮助临床医师选择最佳治疗方案。2020年版该指南将进一步总结循证医学证据，优化决策推荐，为推动建立乳腺癌规范化诊疗体系贡献力量。.
