JAMA:治疗胶质母细胞瘤——TTFields加替莫唑胺效果改善显著

2015-12-16 崔倩 译 MedSci原创

胶质母细胞瘤是成人中枢神经系统的的最具破坏性的原发恶性肿瘤。多数患者死于诊断后的1〜2年内。肿瘤治疗电场(TTFields)是一个局部区域传递抗有丝分裂的治疗,干扰细胞分裂和细胞器组装。

胶质母细胞瘤是成人中枢神经系统最具破坏性的原发恶性肿瘤。多数患者死于诊断后的1-2年内。肿瘤治疗电场(TTFields)是一个局部区域传递抗有丝分裂的治疗,干扰细胞分裂和细胞器组装。

该研究的目的是评估胶质母细胞瘤患者放化疗后使用替莫唑胺维持治疗结合TTFields的疗效和安全性。

放化疗结束后,胶质母细胞瘤患者被随机(2:1)分配接受维持治疗加TTFields和替莫唑胺(n=466)或单独替莫唑胺(n=229)治疗(中位时间从诊断到随机化,两组均为3.8个月)。该研究纳入了计划的700例患者中的695例,患者来自于2009年7月和2014年11月间美国、加拿大、欧洲、以色列和韩国的83个中心。基于该计划的中期分析的结果,该试验被终止。

治疗TTFields(>18个小时/天),通过4个传感器阵列放置在剃光头皮和连接到便携式医疗设备连续给予患者。替莫唑胺(150-200mg/m2/d)被给予5天/28天,为一周期。

主要终点是意向性治疗人群的无进展生存期,符合方案人群总生存期(n=280)(0.01意义阈值)为次要终点(0.006意义阈值)。这种预先设定的中期分析是在至少18个月的随访后的第一次315例患者中进行。

中期分析纳入210例随机分配到TTFields加替莫唑胺的患者和105例随机接受单独替莫唑胺的患者,并在中位随访38个月(18-60个月)时进行。TTFields加替莫唑胺组的中位无进展生存在意向治疗人群中为7.1个月(95%Cl,5.9-8.2个月),单独替莫唑胺治疗组为4.0个月(95%Cl,3.3-5.2个月)(危险比[HR],0.62[98.7%Cl,0.43-0.89];P=0.001)。在符合方案人群中TTFields加替莫唑胺组中位总生存期为20.5个月(95%CI,16.7-25.0个月)(n=196),替莫唑胺单独组为15.6个月(95%Cl,13.3-19.1个月)(n=84)(HR,0.64[99.4%Cl,0.42-0.98];P=0.004)。

在这一中期分析中,315例胶质母细胞瘤患者完成了标准的放化疗后,增加TTFields到维持替莫唑胺化疗中能够显著延长无进展生存期和总生存期。
