有研究表明,小剂量阿司匹林的使用可能降低癌症发病率和死亡率,但其对胃腺癌生存的影响尚不清楚。国外团队开展了相关研究,旨在评估在胃腺癌胃切除术后服用阿司匹林是否能改善长期生存。相关结果发表在Gastric Cancer杂志上。

这项以人群为基础的队列研究包括了2006年至2015年瑞典胃腺癌而行胃切除术的患者,并在整个2020年进行了随访。术前1年、2年、3年及胃切除术后1年暴露于每日低剂量(75-160 mg)阿司匹林与5年全因死亡率(主要结局)和疾病特异性死亡率相关。多变量Cox回归分析提供了95%可信区间(CI)的危险比(HR),调整了年龄、性别、教育程度、历年、共病、他汀类药物使用、肿瘤位置、肿瘤分期、新辅助化疗、胃切除手术的外科医生数量和手术根治性。

研究纳入2025例患者中,其中545例(26.9%)患者在手术时使用阿司匹林。在服用阿司匹林的患者中,178人(32.7%)术后没有再服用阿司匹林。约56例(2.8%)患者在胃切除术后一年内开始使用阿司匹林。52例(9.5%)阿司匹林服用者和91例(6.2%)非阿司匹林服用者在手术90天内死亡。

Kaplan–Meier曲线表明,服用和未服用阿司匹林患者的生存没有统计学差异。

术前1年内使用阿司匹林并没有降低调整后的5年全因死亡率(HR = 0.98, 95% CI 0.85-1.13)或疾病特异性死亡率(HR = 1.00, 95% CI 0.86-1.17)风险。

术前2年内(HR = 0.98, 95% CI 0.84-1.15)或3年内(HR = 0.94, 95% CI 0.79-1.12)服用阿司匹林并没有降低5年全因死亡率的风险。同样,术前和术后1年使用阿司匹林的患者,5年全因死亡风险均未出现任何降低(校正后HR=1.01, 95% CI 0.82-1.25)。

在敏感性分析中,我们排除了291例(14.3%)没有明确治疗目的的胃切除术患者。在对1734名患者的分析中,90天的死亡率为4.0%。与未服用阿司匹林者相比,服用阿司匹林与5年全因死亡率(调整后的HR=0.92, 95% CI 0.78-1.09)或5年疾病特异性死亡率(调整后的HR=0.94, 95% CI 0.79-1.13)均无相关性。

综上,研究表明,小剂量阿司匹林的使用可能不会提高胃腺癌术后的长期生存率。
