Clin Cancer Res:OS和PFS在胃肠间质瘤之中的联系(meta分析)

2015-01-28 MedSci MedSci原创

目的:胃肠间质瘤是一种相对少见的肿瘤,靶向治疗被用于其进展期的治疗。有关于胃肠间质瘤的临床试验需要长时间的随访和较大的样本量去评估其中位生存时间(OS)。OS是评价其治疗效果的金标准。然而,由于疾病进展导致的治疗方案变化会使得生存评估更加复杂化。建立一个OS的替代的指标可能会使新药审批便利化以及使新的有效治疗手段更快的被广大患者应用。然而,针对不可切除的或转移性胃肠间质瘤目前尚无研究探索这一方面的

目的:胃肠间质瘤是一种相对少见的肿瘤,靶向治疗被用于其进展期的治疗。有关于胃肠间质瘤的临床试验需要长时间的随访和较大的样本量去评估其中位生存时间(OS)。OS是评价其治疗效果的金标准。然而,由于疾病进展导致的治疗方案变化会使得生存评估更加复杂化。建立一个OS的替代的指标可能会使新药审批便利化以及使新的有效治疗手段更快的被广大患者应用。然而,针对不可切除的或转移性胃肠间质瘤目前尚无研究探索这一方面的问题。

试验设计:通过文献回顾收集了在1995.1至2013.12之间的14个临床试验和5个观察性研究中的数据,这其中应用了29种治疗方案,2189名患者参加。加权直线回归被用来评估针对每种治疗方案,中位OS和中位PFS之间的联系,并且对治疗线数、治疗种类、质量评分进行了分层分析。

结果:中位OS和中位PFS之间是存在正相关的关系的。在排除了4个有影响的数据点之后,这种联系仍然存在只是关联程度稍缓和。在分层分析中,OS和PFS之间的联系在越后期的治疗中其关联程度越明显(一线治疗=0.52;二线治疗=0.80;三线或之后的治疗=0.70),并且伊马替尼相对于其他治疗方案,患者的OS与PFS之间的关联程度也更加明显。(0.91VS-0.26—0.69)。

结论:这个分析表明,OS和PFS之间存在相关性,并且该相关性在越后线的治疗中表现得越为明显。这个发现表明,PFS可以成为OS的一个替代指标,然而,分析患者水平的数据时需要确认其在胃肠间质瘤中的有效性。
