SCI REP:输血对结直肠癌切除术后复发和死亡率的影响

由此可见,围手术期输血与治愈性结直肠切除术后癌症预后相关,与贫血状态无关。应进一步研究制定旨在减少输血需求的策略。

输血是否加剧了人类手术后的癌症结局仍然没有定论。近日,Scientific reports杂志上发表了一篇研究文章,研究人员利用一个大型队列来探究围手术期输血对直肠癌(CRC)切除后癌症预后的影响。

在2005年至2014年期间,研究人员确定了在三级医疗中心接受肿瘤切除的I期至III期CRC患者,并于2016年8月进行了评估。倾向评分匹配用于抵消患者特征的不平衡。研究人员使用Cox回归模型分析了术后无病生存(DFS)和总生存(OS)。

在倾向评分匹配之前和之后,研究人员分别分析了4030名和972名患者。Cox回归分析显示输血与匹配前后较短的DFS和OS相关(对于DFS风险比为1.41,95%CI为1.2-1.66; 对于OS 风险比为1.97,95%CI为1.6-2.4)。较大的输血量与较高的总体死亡率相关(≤4单位vs. 0,HR=1.58;>4单位 vs. 0,HR=2.32),但与更多的癌症复发无关。调整协变量后,术前贫血与生存率下降无关。

由此可见,围手术期输血与治愈性结直肠切除术后癌症预后相关,与贫血状态无关。应进一步研究制定旨在减少输血需求的策略。

Blood:输血竟然可以降低镰刀型细胞贫血患儿脑梗死的风险!
