在HER2阳性晚期胃食管腺癌的一线治疗中,曲妥珠单抗联合化疗曾长期是唯一确立的标准,近年才被帕博利珠单抗化疗免疫和泽尼达妥单抗等新策略快速改写[11]。泽尼达妥单抗是HER2双特异性抗体,全球Ⅲ期HERIZON-GEA-01按1:1:1比较泽尼达妥单抗+化疗±替雷利珠单抗与曲妥珠单抗+化疗[7];已发表的NEJM主要分析(中位随访25.9个月)显示两个泽尼达妥单抗组的PFS均优于对照组(12.4、12.4对8.1个月,三联HR 0.63)[8],前期Ⅰb/Ⅱ期ORR达75.8%、中位OS 32.4个月[9],患者数据重建的汇总分析还提示三联较帕博利珠单抗方案降低进展风险(HR 0.78)[12]。
本次ESMO26以LBA79报告该研究的第二次OS中期分析:共914例一线HER2阳性患者,中位随访35.3个月。中位OS三联组27.0个月、双药组22.9个月、曲妥珠+化疗组19.6个月;双药对曲妥珠HR 0.76(95% CI 0.62–0.93,p=0.0088),三联对曲妥珠HR 0.65,而三联对双药HR 0.81、p=0.0502;3年OS率分别为39.8%、31.5%和22.9%。结果由Shitara教授报告,现场另有专家称获益独立于PD-L1状态。
主站新闻与现场数字一致:产业报道同样给出三联中位OS 27.0个月、HR 0.65、随访35.3个月,以及对照组19.6个月、双药22.9个月(HR 0.76,P=0.0088);另一篇新闻则点明三联相对双药的差异未达统计显著,与现场p=0.0502相呼应。
就证据推进而言,此前的阳性结果主要落在PFS[8],本次在更长随访下把OS差距坐实:双药组对曲妥珠单抗取得显著OS获益,三联数值最佳、3年OS率接近40%,有现场讨论者据此提出新的1L标准将是泽尼达妥单抗±替雷利珠单抗。但试验为开放标签,三联对双药p=0.0502未跨过显著性界值,是否常规叠加替雷利珠单抗仍有争论,与帕博利珠单抗方案的比较目前也只有间接重建证据[12]。

Erman Akkus@Erman_Akkus レ点🧬💉💊@m0370 引用@#ESMO26 | HERIZON-GEA-01 – Updated OS Her2 positive gastric/ge cancer At 35.3 months of follow-up, zanidatamab + CT now shows a significant OS benefit over trastuzumab + CT: 22.9 vs 19.6 months (HR 0.76; p=0.0088). With the addition of tislelizumab, median OS increased to 27 months, but the additional benefit was statistically borderline (HR 0.81; p=0.0502). Considering toxicity, we need to carefully analyze which patients should receive the triplet regimen.
