ASCO 2014:10年临床试验证实转移性结直肠癌治疗方案无显著差别

2014-06-05 佚名 浮米网

第50届ASCO全体会议重点报告了旨在比较四种最常见的无KRAS基因突变的转移性结直肠癌(Metastatic colorectal cancer,CRC)患者采用一线方案(first-line regimens)的III期临床试验结果:试验失败。研究人员指出,该试验的失败正体现了药物靶向治疗疾病的实验方法存在障碍,然而这只是冰山一角,需要学习的东西还有很多。 在这项试验中,患者存活期中位数(M

第50届ASCO全体会议重点报告了旨在比较四种最常见的无KRAS基因突变的转移性结直肠癌(Metastatic colorectal cancer,CRC)患者采用一线方案(first-line regimens)的III期临床试验结果:试验失败。研究人员指出,该试验的失败正体现了药物靶向治疗疾病的实验方法存在障碍,然而这只是冰山一角,需要学习的东西还有很多。

在这项试验中,患者存活期中位数(Median survival)约为29个月,不管使用哪种化疗方案:罗氏(Roche AG)的贝伐单抗(Bevacizumab)和化疗、礼来公司(Eli Lilly)的西妥昔单抗(Cetuximab)和化疗。而使用奥沙利铂(FOLFOX)或伊立替康(FOLFIRI)疗效也无多大差别。因此,无法确定哪种方案更好。

该临床试验选择了1 137例未接受治疗的转移性结直肠癌患者,并随机分配,或采用贝伐单抗联合化疗方案,或采用西妥昔单抗联合化疗方案,化疗方案则依据医师的建议,26.6%的患者选择奥沙利铂,剩余73.4%则选择伊立替康,患者跟踪治疗中位数为24个月。结果发现患者的总体生存期(OS)或无进展生存期(PFS)并无明显差异。使用贝伐单抗的患者组的OS和PFS分别为29和10.8个月。而使用妥昔单抗的患者组则分别为29.9和10.4个月。实验方案均无副作用发生。因两组患者OS都为29个月,因而其将会成为CRC临床试验的新的参照标准。虽然有10%的患者生存期超过了5年,但该结果适用于某些实际情况而非学术上的理想情况。

这项临床试验持续10年,并采集了44 000个活体样本。研究人员认为在确定合适的试验对象时,或需要进一步进行分子水平的分析。同时,增加样本量也有助于发现治疗方案的区别,提高实验准确度。

对于局部晚期直肠癌(LARC),在高质量的全直肠系膜切除术(TME )中允许省略术前放化疗(PCRT),局部复发的情况不很常见。疾病转移的风险可部分通过磁共振成像(MRI)获得预测。然而术前放化疗并不能惠及所有的LARC患者,且与长期的患病率相关。 化疗( Cty )可减少局部复发的机会,但术后辅助化疗的依从性差,因此CRT后化疗的疗效已受到质疑。新辅助化疗手段正在原发性结肠癌和直肠癌(FOXTR
