JGH:低剂量阿司匹林可降低手术后结直肠癌的死亡率

2019-06-28 不详 MedSci原创

阿司匹林在结直肠癌(CRC)中的化学预防作用已经得到了很大的认可,但其对CRC诊断和手术后患者的益处尚不清楚。本研究旨在探讨小剂量阿司匹林对手术后CRC患者死亡率的影响。

背景和目的
阿司匹林在直肠癌(CRC)中的化学预防作用已经得到了很大的认可,但其对CRC诊断和手术后患者的益处尚不清楚。本研究旨在探讨小剂量阿司匹林对手术后CRC患者死亡率的影响。

方法
研究人员对患者进行随机分组分析:(i)在CRC诊断前服用阿司匹林并在手术后继续或停用阿司匹林的患者和(ii)在CRC诊断前从未使用过阿司匹林,在手术后接受或未接受阿司匹林的患者。与CRC相关的死亡率和全因死亡率是主要观察结果和次要观察结果。

结果
本项共纳入13528名CRC患者。在CRC诊断前使用常规阿司匹林的3292例患者中,2658例(80.7%)持续服用阿司匹林,634例(19.3%)在手术后停用阿司匹林。持续使用阿司匹林显着降低CRC相关死亡率(SHR:0.69,95%置信区间[CI]:0.59-0.81)和全因死亡率(HR:0.61,95%CI:0.55-0.68)。在CRC诊断前未使用阿司匹林的10 236名患者中,1054名患者(10.3%)在手术后接受阿司匹林治疗,9182名患者(89.7%)未接受阿司匹林治疗。手术后开始使用阿司匹林可降低CRC相关死亡率(SHR:0.88,95%CI:0.80-0.98)和全因死亡率(HR:0.87,95%CI:0.81-0.94)。

结论
无论在手术前使用阿司匹林治疗CRC,手术后使用低剂量阿司匹林可降低CRC相关死亡率和总体死亡率的风险。
