JCO:塞来昔布不改善晚期NSCLC生存

2011-10-15 MedSci原创 MedSci原创

  荷兰一项研究表明,化疗基础上加用塞来昔布并不能改善晚期非小细胞肺癌(NSCLC)患者生存。研究论文10月11日在线发表于《临床肿瘤学杂志》(J Clin Oncol)。   该研究是一项Ⅲ期研究,纳入了未接受过化疗、东部肿瘤协作组(ECOG)体能状态(PS)评分为0~2分、有足够器官功能且经病理检测确诊的Ⅲ b/Ⅳ期NSCLC患者。受试者接受每3周一个周期多西他赛和卡铂化

  荷兰一项研究表明,化疗基础上加用塞来昔布并不能改善晚期非小细胞肺癌NSCLC)患者生存。研究论文10月11日在线发表于《临床肿瘤学杂志》(J Clin Oncol)。

  该研究是一项Ⅲ期研究,纳入了未接受过化疗、东部肿瘤协作组(ECOG)体能状态(PS)评分为0~2分、有足够器官功能且经病理检测确诊的Ⅲ b/Ⅳ期NSCLC患者。受试者接受每3周一个周期多西他赛和卡铂化疗,共5个周期,并随机给予每日两次塞来昔布400 mg或安慰剂治疗。研究采用免疫组化法检测了肿瘤细胞的COX-2表达。主要终点为总生存期(OS)。

  结果显示,从2003年7月至2007年12月,共有561例患者接受随机治疗。研究中观察到的毒性反应轻微,未观察到心血管事件风险升高。塞来昔布和安慰剂组肿瘤缓解率分别为38%和30%(P=0.08),中位无进展生存期分别为4.5和4.0个月(P=0.25),中位OS均为8.2。 COX-2表达不能独立预测患者生存状况。仅COX-2低表达者可获益于塞来昔布治疗,但在校正了各种预后因素后,这种益处并不显著。
