2025 年 St. Gallen 国际乳腺癌大会共识投票结果公布!

引言

St. Gallen 国际乳腺癌大会(SG-BCC)自 1985 年起由瑞士圣加仑州立医院(St. Gallen Cantonal Hospital)发起,是全球早期乳腺癌诊疗领域的权威盛会。2025 年 3 月 15 日,第 19 届 St. Gallen 国际乳腺癌大会在奥地利维也纳盛大开幕。此次大会汇聚了来自 130 多个国家的 3000 余名专家学者,共同聚焦乳腺癌精准治疗的最新进展。


自 2002 年起,大会首创了「专家投票共识」机制,通过全球顶尖专家对争议问题的深入讨论与投票,形成了具有权威性的临床指南 ——「St. Gallen 国际乳腺癌共识」,该共识对乳腺癌的诊治产生了深远影响。例如,2005 年的大会提出了基于 ER/PR/HER2/Ki-67 的分子分型体系,将乳腺癌分为 Luminal 型、HER2 阳性型及三阴性亚型,为精准治疗奠定了坚实基础。2011 年的会议进一步简化了分型方法,提出了基于免疫组化的替代指标(如 ER/PR/HER2/Ki-67),使得分子分型更易在临床中普及,推动了全球乳腺癌诊疗标准的统一。

在本届大会的最后一场会议中,由全球各地的乳腺癌专家组成的小组深入讨论了过去两年早期乳腺癌患者治疗的进展,投票产生了新的 St. Gallen 国际乳腺癌共识指南。当地时间 2025 年 3 月 15 日(星期六)08:30 至 13:00,圣加仑国际会议的共识投票环节圆满结束。

丁香园肿瘤时间特对本届大会的投票环节进行了回顾总结,完整的指南共识内容将于后续的 ESMO 官方杂志《肿瘤学年鉴》(Annals of Oncology)上正式发布。
