HBV 感染者耐药基因突变与肝细胞癌的相关性分析
Correlation between drug -resistance gene mutations and hepatocellular carcinoma in patients with hepatitis B virus infection
摘要
Abstract
Objective To investigate the correlation between hepatitis B virus (HBV)drug -resistance gene mutations and hepatocellular carcinoma (HCC).Methods The clinical data of treatment -experienced patients,who underwent examination for HBV drug -resistance gene mutations in Beijing Ditan Hospital from January 1 to December 31,2013,and still had detectable HBV DNA after being treated with nucleos(t)ide analogues,were collected.All the patients were followed up,and the development of HCC was considered as the clinical out-come.The correlation between drug -resistance gene mutations and the development of HCC in patients with HBV infection was analyzed. The chi -square test was used for comparison of categorical between groups,the t -test was used for comparison of continuous data between two groups,and the log -rank test was used for comparison of the incidence of HCC between two groups.Results A total of 227 patients were enrolled in this study.According to the results of the detection of HBV drug -resistance gene mutations,103 patients (103 /227, 45.37%)had no drug -resistance gene mutations and 124 (124 /227,54.63%)had drug -resistance gene mutations.There were no sig-nificant differences between the mutation group and the non -mutation group in HBV DNA load (5.19 ±1.60 log10 IU /ml vs 5.44 ±1.75 log10 IU /ml,t =-1.134,P =0.258)and the percentage of patients with liver cirrhosis (24.19% (30 /124)vs 16.50% (17 /103),χ2 =2.026,P =0.155).The median follow -up was 28 months (range 4 -58 months),and the incidence of HCC was 7.49% (17 /227).A-mong the patients with HBV drug -resistance gene mutations,12 (12 /124,9.68%)developed HCC,and among those without HBV drug-resistance gene mutations,5 (5 /103,4.85%)developed HCC.Among the patients who developed HCC,70.59% (12 /17)had HBV drug -resistance gene mutations at baseline;among the patients who did not develop HCC,53.33% (112 /210)had HBV drug -resistance gene mutations at baseline.Conclusion The patients with poor control of HBV DNA during antiviral therapy have a comparable incidence of HCC to those not treated with antiviral therapy,with a relatively high risk of developing HCC;the treated patients with HBV drug -resist-ance gene mutations may have a higher risk of HCC than those without such mutations,which needs to be confirmed by the studies with a longer follow -up period and a larger sample size.关键词
