摘 要:目的:探讨启东肝癌高发区乙型肝炎病毒e抗原(hepatitis B e antigen,HBeAg)与肝癌发生之间的关系。方法:利用1992年在启东建立的由807例乙型肝炎病毒表面抗原(hepatitis B surface antigen,HBsAg)携带者和761例性别、年龄匹配的HBsAg阴性者组成的肝癌前瞻性队列,分析1992年5月-2010年3月肝癌发生与HBeAg之间的关系。结果:队列观察总人数为24715人年。HBsAg阳性组中156例发生肝癌,发生率为1288.83/10万人年;HBsAg阴性组中9例发生肝癌,发生率为71.37/10万人年。肝癌发病在HBsAg(+)/HBeAg(-)和HBsAg(+)/HBeAg(+)组中的相对危险度分别为13.25[95%可信区间(con?dence interval,CI)为6.67~26.33,P<0.001]和28.05(95%CI为13.87~56.73,P<0.001)。在HBsAg阳性者中,HBeAg效价<24、1:24~1:27、1:28~1:212和>212者其罹患肝癌的风险分别是HBeAg阴性者的2.55(95%CI为1.54~4.22,P<0.001)、5.02(95%CI为2.89~8.73,P<0.001)、1.71(95%CI为0.91~3.18,P>0.05)和1.19(95%CI为0.64~2.23,P>0.05)倍。结论:HBeAg是预测肝癌高危的一个重要指标,且低效价者的危险度更高。Objective:To explore the correlation between hepatitis B virus e antigen(HBeAg) and hepatocellular carcinoma(HCC) in residents of Qidong — a high-risk area of HCC in Jiangsu Province,China.Methods:This study included 807 hepatitis B virus surface antigen(HBsAg) carriers and 761 age-and gender-matched HBsAg(-) controls enrolled in a prospective cohort in Qidong during 1992.The relationship between the occurrence of HCC and HBsAg was analyzed during the follow-up period from May 1992 to March 2010.Results:A total of 24 715 person-years(PY) was observed.Of 807 cases in HBsAg-positive group,156 cases had developed HCC,and the incidence rate of HCC was 1 288.83/100 000 PY;while in HBsAg-negative group,9 of 761 cases had developed HCC,and the incidence rate of HCC was 71.37/100 000 PY.The relative risks(RRs) of HCC were 13.25(95% confidence interval:6.67-26.33;P〈0.001) and 28.05(95% confidence interval:13.87-56.73;P〈0.001) in HBsAg(+) /HBeAg(-) group and HBsAg(+) /HBeAg(+) group,respectively.In the HBsAg(+) group,the RRs for HCC of the four subgroups(HBeAg titer〈24,1:24-1:27,1:28-1:212,and〉212) were 2.55(95% confidence interval:1.54-4.22;P〈0.001),5.02(95% confidence interval:2.89-8.73;P〈0.001),1.71(95% confidence interval:0.91-3.18;P〉0.05),and 1.19(95% confidence interval:0.64-2.23;P〉0.05) folds higher than that of HBeAg(-) subgroup,respectively.Conclusion:HBeAg is an essential predictive factor for the development of HCC.The patients with low titers of HBeAg are at a high-risk of HCC.
