本次 ESMO 2026 乳腺癌专场集中呈现三项内分泌治疗相关研究的长期或生物标志物数据:延长辅助芳香化酶抑制剂(NSABP B-42)、不同芳香化酶抑制剂的首选与序贯策略对比(GIM3 FATA),以及口服选择性雌激素受体降解剂联合 mTOR 抑制剂的生物标志物回顾性分析(evERA)。背景文献中关于循环肿瘤细胞(CTC)干细胞标志物、上皮间质转化标志物及 HER2 表达异质性的系统表征 [1][3][4],以及不同 CTC 检测平台的方法学比较 [5][2],反映了液体活检技术在转移性及早期乳腺癌中对肿瘤异质性和耐药机制的持续探索,为 evERA 研究中 ctDNA 肿瘤分数、ESR1 突变亚型及 TP53/PIK3CA 共突变亚组分析提供了方法学参照。
NSABP B-42 试验 15 年随访结果显示,延长来曲唑辅助治疗较安慰剂可显著降低远处复发风险,但未转化为总生存获益:淋巴结阳性人群绝对获益 4.4%,淋巴结阴性人群 1.6%(无统计学意义);无病生存期(DFS)、无乳腺癌事件生存期(BCFI)及远处无复发生存期(DR)均有适度但显著改善,骨质疏松性骨折风险未增加。
GIM3 FATA 终极分析纳入 3697 例绝经后 HR+ 早期乳腺癌患者,比较阿那曲唑、来曲唑、依西美坦的首选与序贯(先用他莫昔芬 2 年)策略:首选与序贯在 DFS(HR 0.95,95% CI 0.82–1.09)和 OS(HR 0.88,95% CI 0.74–1.06)均无显著差异;10 年 DFS 分别为阿那曲唑 79.1%、来曲唑 76.6%、依西美坦 74.2%(总体 p=0.028),经调整后依西美坦对比阿那曲唑 DFS HR 1.23(95% CI 1.04–1.46),提示依西美坦疗效相对较弱;10 年 OS 三药无显著差异(p=0.25)。结论倾向于依据耐受性、合并症及成本个体化选择。
evERA 回顾性生物标志物分析显示,吉瑞德联合依维莫司的 PFS 获益在不同 ctDNA 肿瘤分数水平、ESR1 突变亚型(Y537S HR 0.35)以及 TP53 突变/PIK3CA 突变共存亚组中均得以维持。局限方面,B-42 与 FATA 均为成熟辅助治疗试验,长期随访虽确立了 DFS/DR 获益但均未达 OS 显著性;evERA 为 II 期试验的探索性亚组分析,样本量与统计效能不足以支持确证性结论,且 ctDNA 与 CTC 检测平台的可比性仍待进一步验证。

Aya Mohamed | MSc, MD 🎗@Dr_Oncologista Rebecca Shatsky, MD@Dr_RShatsky 总是很有趣,看到人们走到麦克风前提出那些疯狂、非常宽泛且不一定切题的问题。😳 作为主持人要应对这些 #ESMO26 真的很难 我并不反对刚才说的……但是。 #Breastcancer

Co-primary: DFS by schedule and by AI. ➡️ Upfront vs switch: DFS HR 0.95 (0.82–1.09); OS HR 0.88 (0.74–1.06) ➡️ 10-year DFS 79.1% anastrozole, 76.6% letrozole, 74.2% exemestane (global p=0.028) ➡️ Exemestane vs anastrozole: adjusted DFS HR 1.23 (1.04–1.46). 10-year OS across AIs: no statistically significant difference (p=0.25) ✅ No schedule superior; exemestane associated with worse DFS. Choice should be individualized by tolerability, comorbidities and cost. #BreastCancer 🎙️ Pietro De Placido 👥 Laura Arenare · Erica Pietroluongo · Giancarlo Bisagni · Maria Sarobba · Antonio Russo · Ferdinando Riccardi · Lucia Del Mastro · Antonio Pazzola · Francesco Cognetti · Jennifer Foglietta · Stefania Gori · Francesco Nuzzo · Adriano Gravina · Michelino De Laurentiis · Roberto Bianco · Grazia Arpino · Sabino De Placido · Ciro Gallo · Francesco Perrone (4Sight Made from Abstracts publicly available at the ESMO website) Pinging OncoAlert Breast Cancer Faculty @matteolambe @aftimosp @E_de_Azambuja @DrSGraff @ErikaHamilton9 @hoperugo @stolaney1 @BianchiniGP @aftimosp @kevinpunie @ElisaAgostinett @to_be_elizabeth @GaiaGriguolo @JankovicK @raalbany @JavierCortesMD @JaniceTNBCmets @Prof_Nadia_H @LoiSher @jamecancerdoc @Lucarecco @Dr_Oncologista
