摘要:

BRCA基因(包括BRCA1和BRCA2)的胚系突变是家族性乳腺癌、卵巢癌等肿瘤的核心风险因素。在人群中,特别是已有肿瘤家族史的高危人群中,BRCA基因检测可以发挥预防性管理作用,有助于降低此类遗传性疾病的死亡率和社会危害。近年来基于二代测序技术的BRCA胚系突变检测方案逐步落地,检测可及性不断增强。为了进一步规范相关检测工作,完善中国人群中胚系突变筛查的工作流程,本共识制定小组依托中国抗癌协会肿瘤标志专业委员会和上海市抗癌协会肿瘤标志物专业委员会,采用循证医学方法,在文献检索的基础上,对目前在人群中开展BRCA胚系突变检测过程中所共同关注的筛查开展场景、技术方案、质量控制、结果解读与报告、遗传咨询等热点问题形成带有质量等级评价、证据综合的初步推荐意见,并采用多学科专家讨论、德尔菲问卷调查等形式,对专家意见进行调查汇总、归纳梳理和反复修改,最后形成了《基于中国人群的BRCA胚系突变筛查专家共识(2024年版)》,以期为中国人群的BRCA胚系突变筛查提供证据借鉴和规范依据,并为后续的相关指南制订奠定基础。

Abstract:

Germline mutations in BRCA genes (including BRCA1/2) are the major risk factors for hereditary tumors including breast and ovarian cancer. Population based BRCA gene screening, particularly in high-risk individuals with a family history of cancer, can play a preventive role by reducing mortality and societal impact of these genetic diseases. Recent years have witnessed the increasing accessibility of BRCA germline mutation testing based on next generation sequencing technology. To further standardize the workflow for BRCA germline mutation screening in the Chinese population, a consensus development group was established by the China Anti-Cancer Association Tumor Biomarker Professional Committee and the Shanghai Anti-Cancer Association Tumor Biomarker Professional Committee. Using an evidence-based approach and building upon literature reviews, the group formulated preliminary recommendations with quality assessments and evidence synthesis regarding common concerns in the process of BRCA germline testing in the population, including screening scenarios, technical approaches, quality control, result interpretation and reporting, as well as genetic counseling. Through multidisciplinary discussions and Delphi questionnaire survey "expert consensus on population-based BRCA germline mutation screening in China (2024 edition)" was developed after summarization and revision. This consensus aims to provide evidence-based guidance and regulatory foundations for BRCA germline mutation screening in the Chinese population and lay the groundwork for further guideline development.
