JAMA:粪便免疫化学试验前口服阿司匹林不能增加肿瘤检出率

2019-05-09 MedSci MedSci原创

研究认为,粪便免疫化学试验前口服阿司匹林,不能显著增加晚期结直肠肿瘤检出敏感度

粪便免疫化学法检测血红蛋白广泛应用于直肠癌(CRC)筛查。观察研究表明,阿司匹林可提高粪便免疫化学试验检测晚期肿瘤的敏感性,特别是在男性中。近日研究人员考察了粪便取样前2天单次口服300毫克阿司匹林对粪便免疫化学试验敏感性的影响。

2422名40-80岁的参与者,计划进行结肠镜检查,近期未使用阿司匹林或其他抗血栓药物,随机服用300 mg阿司匹林(n=1208)或安慰剂(n=1214)。主要结果是在2个预定义的限度(10.2和17-μg HB/g粪便)进行定量粪便免疫化学法检测晚期肿瘤(直肠癌或晚期腺瘤)的敏感性。

在2422例随机化患者(平均年龄59.6岁,,男性1219例,占50%)中,2134例(78%为初筛结肠镜,22%为诊断结肠镜)参与数据分析。其中晚期肿瘤224例(10.5%),其中CRC 8例(0.4%),晚期腺瘤216例(10.1%)。在粪便为10.2-μg Hb/g时,阿司匹林组和安慰剂组的敏感性分别为40.2%和30.4%(差异9.8%,95%CI:-3.1%至22.2%,P=0.14),在粪便为17-μg Hb/g时,阿司匹林组为28.6%,安慰剂组为22.5%(差异6.0%,95%CI:-5.7%至17.5%,P=0.32)

研究认为,粪便免疫化学试验前口服阿司匹林,不能显著增加晚期结直肠肿瘤检出敏感度。
