Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
we give adefovir 10mg oral tablet, once a day to patients in treatment group.Overall duration of antivirus treatment is according to the guideline of chronic hepatitis B. The indicatons to stop antivirus treatment are as follows:1.to the patients with HBeAg(+), they should take medicine for 6-12 months after HBeAg(+) becoming HBeAg(-) and then can stop the antivirus treatment;2.to the patients with HBeAg(-), when HBV-DNA is undetectable for three times with a interval of 6 months,they can choose to stop treatment;3.to cirrhosis patients, we recommend taking antivirus treatment for whole life.

Outcomes
Primary outcome [1] 262117 0
the prognosis of HCC patients treated by adefovir or not, defined by overall survival(OS) and disease free survival(DFS)
Timepoint [1] 262117 0
AFP,Ultrasound monthly and MRI or CT half a year for first 2 years post-surgery, then AFP,Ultrasound every 2 months and MRI or CT half a year up to 5 years post-surgery.HBV-DNA should be checked every 3 months.
Secondary outcome [1] 273194 0
the rate of HBV reactivation after liver resection and the change of liver function. The patients will check serum HBV-DNA every 3 months(in our hospital) and liver function every month(in the local hospital). If the HBV-DNA increases 10 times or become detectable, it means virus reactivation.
Timepoint [1] 273194 0
to check liver function monthly in the first 2 years and every 2 months after 2 years and HBV-DNA every 3 months after liver resection.
