Br J Cancer:二甲双胍可改善胃腺癌患者的预后

2021-05-25 xiaozeng MedSci原创

胃癌作为一种常见的疾病,患者的总体预后较差。

胃癌作为一种常见的疾病,患者的总体预后较差。在2018年里,全球范围内有近80万人死于胃癌(每12例死亡中有1例死于胃癌),是癌症相关死亡的第二大主要原因。

胃腺癌是胃癌的主要组织学类型(> 95%)。胃腺癌的治疗策略一般采用多学科方法,其中以手术切除(胃切除术)为治疗的主要手段,而无法切除或转移性疾病的患者通常采用化疗和靶向治疗方法。


尽管目前已对上述的治疗方法进行改善,但患者的总体生存率仍未得到很大的改善。因此急需开发改善胃腺癌患者生存率的新疗法。

最近的研究表明,二甲双胍作为糖尿病的一线药物,可以改善结肠癌和前列腺癌患者的预后。相关实验研究也显示,二甲双胍可以抑制胃癌细胞的增殖并抑制转移,然而,目前相关的研究仍有限。


该研究是一项基于瑞典人群的队列研究,研究对象为2005-2018年被诊断为胃腺癌的糖尿病患者。该数据主要来自四个国家卫生数据注册中心:处方药注册中心、癌症注册中心、患者注册中心和死亡原因登记处。

二甲双胍治疗胃腺癌患者的Kaplan-Meier生存曲线

研究人员通过多变量Cox风险回归分析评估了胃腺癌诊断前使用二甲双胍与患者疾病特异性死亡率和全因死亡率之间的关系。并根据患者的性别、年龄、合并症、使用非甾体类抗炎药或阿司匹林以及使用他汀类药物情况调整了风险比(HRs)。


结果显示,相比于非使用者,二甲双胍使用者的疾病特异性死亡率(HR=0.79)和全因死亡率(HR=0.78)降低。在女性患者(HR=0.66)、III或IV期肿瘤患者(HR=0.71=)以及合并症最少的患者(HR=0.71)中,该相关性更强。

二甲双胍使用者与非使用者的累积死亡率曲线比较

总而言之,该研究结果揭示,二甲双胍可改善患有糖尿病的胃腺癌患者的生存率。
