JNCCN:质子泵抑制剂(PPI)可能降低结直肠癌患者的生存

质子泵抑制剂(PPI)是临床上常用的药物。非癌人群观察性研究中发现,长期服用PPI可出现严重的不良后果,比如增加全因死亡率,血管疾病,肾脏疾病,低镁血症以及肿瘤等。体内实验发现PPI似乎可有增强某些抗肿瘤药物的活性。但是,其中的机制不明确。也有观察性和回顾性研究发现,PPI可以降低卡培他滨的疗效,药代动力学以及体内实验也未能解析两者的关系。

因此,来自澳大利亚的研究团队,在Journal of The National Comprehensive Cancer Network (JNCCN) 杂志发表了一项研究数据,评估PPI与氟尿嘧啶治疗为基础的晚期结直肠癌的生存关系。

该研究主要为随机对照研究的二次分析,纳入了6项研究,共5594例患者,其中902例患者使用PPI(使用PPI定义为:自临床实验开始服用任何PPI至少7天)。主要研究总生存(OS),无进展生存(PFS),以及亚组分析,如卡培他滨或5-氟尿嘧啶等。使用随机效应模型计算HR和95%CI。

研究数据显示,PPI 使用跟结直肠癌患者较差的OS相关 (pooled HR, 1.20; 95% CI, 1.03–1.40; P=0.02; I 2 = 69%);

                      OS分析

同样, PPI 使用跟结直肠癌患者较差的PFS相关 (overall pooledHR, 1.20; 95% CI, 1.05–1.37; P=0.009; I 2 = 65%) 。

             PFS分析

而亚组分析发现PPI的使用在各治疗亚组中的生存关系跟与总体人群中相似。

                  亚组分析

综上,PPI的使用跟氟尿嘧啶为基础治疗的晚期结直肠癌患者较差预后有关。当然,这个需要更进一步的研究。但是也同时提醒我们临床医生,对于这部分患者需要谨慎使用PPI。
