🧬 当免疫治疗产生完全缓解时,手术是否仍应自动进行?
@OncoAlert
在 #ESMO26 上,II 期 GERCOR-GONO DEWI 研究的首次中期分析探讨了局部 dMMR/MSI-H 胃食管腺癌中最具挑战性的器官保留策略之一:
dostarlimab + 观察等待。
📊 24 例可评估患者
➡️ 1 年 cCR:62.5%(15/24)
➡️ 在中位随访 16.2 个月时,1 年 cCR 患者无复发或死亡
➡️ 3-4 级 dostarlimab 相关不良事件:21%
➡️ 9 名患者接受手术 — 均实现 R0 切除
🎯 为何这很重要:这不仅是免疫治疗疗效的故事,更可能是治疗理念的转变。
对于选定的 dMMR/MSI-H 患者,未来可能从“治疗,然后手术”转向“治疗,深入评估,并在肿瘤学安全时保留器官”。
当前的关键挑战在于如何自信地识别真正的完全缓解者,以及该缓解能持续多久。
这是向生物标志物驱动的器官保留迈出的迷人一步。

Watch-and-wait (W&W) strategy for dostarlimab in localized deficient dMMR/MSI-H gastroesophageal adenocarcinoma (GEA): Results from the first interim analysis of the GERCOR-GONO DEWI phase II study
https://esmocongress.esmo.orgOncoAlert 4Sight Abstracts to be Presented at #ESMO26 Watch-and-Wait Strategy for Dostarlimab in Localized dMMR/MSI-H Gastroesophageal Adenocarcinoma: Results From the First Interim Analysis of the GERCOR-GONO DEWI Phase II Study 🔬 Phase II, first interim analysis (24 evaluable patients): dostarlimab with a watch-and-wait strategy in localized dMMR/MSI-H gastroesophageal adenocarcinoma. Primary endpoint: 1-year cCR without surgery. ➡️ 1-year cCR: 62.5% (15/24) ➡️ No relapse or death in patients with 1-year cCR (median follow-up 16.20 mo) ➡️ Grade 3–4 dostarlimab-related AEs: 21%; 9/24 underwent surgery, all R0 ✅ dostarlimab led to a 62.5% 1-year cCR at the first interim analysis, enabling organ preservation. 🎙️ Thierry André 👥 Christelle de la Fouchardière (4Sight Made from Abstracts publicly available at the ESMO website) @CathyEngMD, @BenWestphalen, @graokane, @NiuSanford, , @GillSharlene, @pashtoonkasi, @DrVilmaPBarcia, @Erman_Akkus, @GIMedOnc, @UOzkerim, @MarioBalsaMD, @p_ciracimd, @DraMartinezLago, @DaisukeKotani, @Aiims1742, @ARosen380, @realbowtiedoc, @KoheiShitara,在 X 查看被引用的帖子
