ANN ONCOL:替莫唑胺联合伊立替康治疗携带MGMT甲基化的晚期结直肠癌患者

2018-08-26 MedSci MedSci原创

非随机性研究表明替莫唑胺治疗携带MGMT甲基化的转移性结直肠癌患者缓解率可达到10%。ANN ONCOL近期发表了一篇文章,评估伊立替康联合替莫唑胺(TEMIRI)治疗伊立替康敏感,MGMT甲基化/微卫星灶稳定(MSS)的接受过其他治疗的转移性结直肠癌患者的疗效

非随机性研究表明替莫唑胺治疗携带MGMT甲基化的转移性直肠癌患者缓解率可达到10%。ANN ONCOL近期发表了一篇文章,评估伊立替康联合替莫唑胺(TEMIRI)治疗伊立替康敏感,MGMT甲基化/微卫星灶稳定(MSS)的接受过其他治疗的转移性直肠癌患者的疗效。

研究的主要纳入标准为确诊MGMT甲基化,在接受过至少两种方案化疗后疾病进展且伊立替康治疗间隔≥3个月。TEMIRI方案应用6个周期,序贯替莫唑胺维持治疗。主要的研究终点为总缓解率。在2014年12月至2017年6月间,共纳入25例患者。达到了主要的研究终点,6例患者出现部分缓解。中位随访时间15.6个月,中位无进展生存和总生存时间分别为4.4个月和13.8个月。只有4例患者出现≥3级不良反应。所有MGMT免疫组化阳性的患者均无治疗反应。MGMT阴性的患者无进展生存时间长于其他患者,总生存无延长趋势。

文章最后认为,TEMIRI方案用于治疗接受过其他治疗的,伊立替康敏感的MGMT甲基化转移性结直肠癌患者具有安全性和有效性。
