各组累积肝癌发病人数

已有证据表明:他汀类药物对癌症有潜在的保护作用,但目前还没有研究着眼于慢性乙型肝炎病毒(HBV)感染人群。于是为了探讨HBV感染患者中他汀类药物的使用和肝细胞癌(HCC)发病风险之间的关系,来自国立台湾大学的Yu-TseTsan等人进行了研究,研究结果发表在最新一期的JCO上。

这是一项以人群为基础的队列研究,纳入对象来自台湾全民健康保险研究资料库。总计纳入33,413例HBV感染患者,并分别进行随访,以确定1999年以来的肝癌发病率。随访时间1997年-2008年。同时还调查了HBV感染患者他汀类药物,其他降脂药,阿司匹林和血管紧张素转换酶抑制剂的服用情况。Cox比例风险回归模型用于计算HBV感染人群中他汀类药物的使用和肝癌发生的危险比(HR)和95%可信区间。



最终,在328946人年的随访期间,共出现1021例肝癌患者。总发病率为310.4/10万人年。他汀类药物的使用和肝癌的发病风险之间存在剂量-反应关系。以未使用他汀类药物人群作为参照标准(<28cDDDs),他汀类药物累计每日服用剂量(cDDDs)28-90,91-365和>365人群的校正HR分别为0.66(95%CI:0.44-0.99),0.41(95%CI:0.27-0.61)和0.34(95%CI:0.18-0.67)。

由此可得出结论:他汀类药物的使用可能会降低乙肝病毒感染患者的肝癌发病风险。但未来需作进一步的机理研究。
