CD26示恶性胸膜间皮瘤(MPM)化疗反应

2012-03-03 MedSci MedSci原创

  日本和美国学者近期发表于《临床癌症研究》(Clinical Cancer Research)杂志的一项研究提示,CD26表达可作为预测恶性胸膜间皮瘤(MPM)对化疗反应情况的生物标志物。   该研究共纳入79例MPM患者,其中73.4%的肿瘤组织细胞膜表达CD26。   结果显示,大部分上皮型和双相型(混合型)MPM细胞膜表达CD26,而肉瘤型缺乏CD26表达。   

  日本和美国学者近期发表于《临床癌症研究》(Clinical Cancer Research)杂志的一项研究提示,CD26表达可作为预测恶性胸膜间皮瘤(MPM)对化疗反应情况的生物标志物。

  该研究共纳入79例MPM患者,其中73.4%的肿瘤组织细胞膜表达CD26。

  结果显示,大部分上皮型和双相型(混合型)MPM细胞膜表达CD26,而肉瘤型缺乏CD26表达。

  虽然肉瘤型与预后较差有关(P<0.0001),但研究未观察到CD26表达与生存期有显著相关性。

  相反,化疗缓解率有与CD26表达相关的趋势(P=0.053),CD26表达水平越高则化疗缓解率越高。

  此外,CD26表达与接受化疗的患者生存期延长显著相关[中位生存期(MST):18.6个月 对 10.7个月,P=0.0083]。

  CD26表达与接受不含培美曲赛方案治疗患者的生存期延长显著相关(MST:14.2个月 对 7.4个月,P=0.0042),而CD26表达与接受含培美曲赛方案治疗的患者生存期无显著相关性。

  体外研究和微阵列研究显示,CD26高表达的间皮瘤细胞增殖活性高,CD26表达与细胞周期调节、细胞凋亡和化疗耐药性密切相关。
