       化疗药物卡倍他滨(希罗达,基因泰克),越来越频繁的用于治疗结直肠癌,因为HFS的副作用,导致治疗的中断和药物剂量的减少。

       他们怀疑HFS(表现为手掌和脚底的红斑)本质是一种炎症,他们推测,塞来昔布应该会有所帮助。因此研究人员在一项单中心前瞻性随机试验中测试了这项假设。该试验纳入的病人为II期和III期结直肠癌患者,接受卡倍他滨为基础的化疗,加(n=68)或不加(n=71)塞来昔布。

       1级HFS的发生率,卡倍他滨组高于联合组(74.6% vs 57.4%; P = 0.034),2级HFS也如此(29.6% vs 14.7%; P =0.035)。多变量分析表明,使用塞来昔布是影响1级或以上(HR,0.56;P=0.001)和2级或以上(HR,0.41;P=0.005)HFS发生的唯一因素。塞来昔布没有明显降低3级或以上的HFS发生率。
 
       作者得出结论,塞来昔布可以有效和安全防止卡倍他滨相关的HFS。然而,审查这项研究的医生认为,得出这种广泛的结论还为时过早。Steven Vogl医生说到,这项研究很有趣,但是还不足以改变临床实践。他对这项研究有很多关注点,他认为这项研究的设计和执行还不是非常完善。

       Vogl博士说到,我认为这项研究不够明确,为了使之明确,应该加入安慰剂对照,这项研究是随机的,但不是对照的。病人和医生是双盲的。同样不明确的是塞来昔布在其中的作用。如果塞来昔布降低了手足综合征,它是否降低了化疗的疗效?是否给予塞来昔布将比降低药物剂量要好?而且,也不清楚卡倍他滨的最合适剂量是多少。
