医脉通将2015 ASCO胃肠道肿瘤研讨会上的亮点研究总结如下,以飨读者。
第一页:
MM-398组合显示在转移性
第二页:
局部晚期
第三页:
基线AFP水平影响Ramucirumab在HCC中的获益:Andrew X.Zhu教授(Massachusetts总医院癌症中心)提交的REACH III期研究结果显示,该研究发现甲胎蛋白(AFP)水平可以作为晚期
第四页:
小分子MET抑制剂在胃
第五页:
食管癌中微创 vs 开放式食管切除术:Christophe Mariette教授(Claude Huriez大学医院,消化和肿瘤学手术科)在一项III期MIRO研究中,在207例食管癌患者中,将混合微创食管切除术与开放式食管切除术进行了比较。微创组较之开放食管切除术组,术后并发症比率较低(35.9% vs 64.4%;P=0.0001),以及肺部并发症也较低(17.7% vs 30.1%;P=0.037)。30天死亡率无显著差异(试验的每个组为4.9%)。这些发现为可切除的食管癌患者进行微创手术的短期获益提供了证据[5]。
第六页:
将
第七页:
免疫治疗在胃癌中产生应答:39例晚期胃癌患者接受抗PD-1单克隆抗体pembrolizumab治疗,22.2%的出现客观缓解。应答的中位时间是8周。5例(13.9%)患者病情稳定。中位响应的持续时间是24周,范围从8到33周不等。6个月的无进展存活率为24%,6个月的总存活率是69%。中位随访期是8.8个月[7]。
第八页:
放疗和化放疗在降低食管癌
第九页:
较高
第十页:
在PNETs中
第十一页:
另一种血管生成靶向抗体在晚期结直肠癌中的活性:ramucirumab,一种抗血管生成抗体,和二线FOLFIRI化疗组合可推迟转移性结直肠癌患者的疾病进展,略微提高生存期,这些患者之前接受一线治疗后进展。患者经ramucirumab+FOLFIRI治疗有16%不太可能死于他们的疾病,与那些单独接受FOLFIRI治疗的患者相比(P=0.0219)[11]。
第十二页:
MET抑制剂未能延缓胃食管癌疾病进展:Manish A.Shah教授(纽约Presbyterian医院)提交的一项II期试验结果,该试验将FOLFOX+MET抑制剂onartuzumab与FOLFOX+安慰剂在晚期胃食管腺癌患者中进行比较。该试验包括123例患者。在数据截止时,96例患者出现疾病进展,这两个组的结果相似,onartuzumab组的中位无进展生存期为6.77个月,安慰剂组的这一数值为6.97个月。在MET-阳性患者中,接受onartuzumab的患者无进展生存期是5.95个月,安慰剂组是6.8个月。在onartuzumab组的患者中发生的严重不良事件也较为频繁(55% vs 40%)[12]。
