AP&T: 非甾体类抗炎药能降低结直肠癌的风险

2020-04-16 MedSci原创 MedSci原创

尽管非甾体类抗炎药(NSAIDs)降低了结直肠癌(CRC)的风险,但它们在预防结肠镜检查后CRC(PCCRC)中的作用仍未确定。

背景及目的:尽管非甾体类抗炎药(NSAIDs)降低了结直肠癌(CRC)的风险,但它们在预防结肠镜检查后CRC(PCCRC)中的作用仍未确定。本项研究旨在研究NSAIDs是否可降低结肠镜检查阴性后的PCCRC风险。

方法:这是一项回顾性队列研究。研究人员将所有在2005年至2013年间接受结肠镜检查的患者(年龄在40岁以上)纳入本项研究。排除标准包括在结肠镜检查六个月内检测到的CRC,先前有CRC病史的,炎性肠病和先前的结肠切除术的患者。主要观察结果是在结肠镜检查后6到36个月内诊断出PCCRC事件。CRC部位分为近端(近端至脾曲)和远端。校正后的PCCRC与NSAID和阿司匹林的使用采用危险比(aHR)进行比较。

结果:在187897名合格患者中,有21757名(11.6%)是NSAID使用者。854名患者(0.45%)患上了PCCRC(近端癌症:147 [17.2%])。NSAIDs与较低的PCCRC风险相关(aHR:0.54,95%CI:0.41-0.70),但与发展超过3年的CRC(aHR:0.78,95%CI 0.56-1.09)没有关系。近端的aHR为0.48(95%CI:0.24-0.95),远端癌为0.55(95%CI:0.40-0.74)。

结论:基线结肠镜检查阴性后,使用NSAIDs与较低的PCCRC风险相关。
