Ann Oncol:可切除的食管癌:放化疗和手术联合或不联合西妥昔单抗有差吗?

2018-07-13 王淳 环球医学

2018年6月,发表在《Ann Oncol》的一项由德国、瑞士、澳大利亚和法国学者进行的随机开放标签的3期试验,在可切除的食管癌患者中考察了新辅助化疗后放化疗和手术联合或不联合西妥昔单抗的疗效。

2018年6月,发表在《Ann Oncol》的一项由德国、瑞士、澳大利亚和法国学者进行的随机开放标签的3期试验,在可切除的食管癌患者中考察了新辅助化疗后放化疗和手术联合或不联合西妥昔单抗的疗效。

背景:这项开放标签的3期试验比较了放化疗后手术联合或不联合新辅助和辅助西妥昔单抗治疗可切除的食管癌患者的情况。

患者和方法:患者按照1:1的比例随机分配到2个周期的化疗(多西他赛75mg/m2,顺铂75mg/m2)后放化疗(45Gy,多西他赛20mg/m2,顺铂25mg/m2,每周给药一次,共5周)和手术联合或不联合新辅助西妥昔单抗250mg/m2每周一次和辅助西妥昔单抗500mg/m2每半月给药一次共3个月的组中。首要终点为无进展生存期(PFS)。

结果:总计300名患者(中位61岁,男性88%,63%食管腺癌,85%cT3/4a,90%cN+)随机分配到西妥昔单抗(149人)或对照(151人)的组中。西妥昔单抗的R0切除率为95%,对照为97%。两组术后治疗相关的死亡率为6%。西妥昔单抗的中位PFS为2.9年(95% 置信区间[CI],2.0~未达到),对照为2.0年(95% CI,1.5~2.8)(风险比[HR],0.79;95% CI,0.58~1.07;P=0.13);中位总生存期(OS)分别为5.1年(95% CI,3.7~未达到)和3.0年(95% CI,2.2~4.2)(HR,0.73;95% CI,0.52~1.01;P=0.055)。西妥昔单抗组R0切除后局部区域失败的时间显着性长(HR,0.53;95% CI,0.31~0.90;P=0.017),组间远处失败时间无差异(HR,1.01;95% CI,0.64~1.59;P=0.97)。新辅助或术后条件下,西妥昔单抗未增加不良事件。

结论:将西妥昔单抗添加到多模式疗法中,会显着改善可切除的食管癌患者的局部区域控制,造成临床重要但非显着的PFS和OS改善。
