Entecavir for Chronic Hepatitis B in Hepatocellular Carcinoma Patients Underwent Radiofrequency Ablation Therapy
- Conditions
- Chronic Hepatitis BHepatocellular Carcinoma
- Interventions
- Registration Number
- NCT01270178
- Lead Sponsor
- Taipei Veterans General Hospital, Taiwan
- Brief Summary
Persistent replication of HBV (47-55%) is frequently found in patients with HCC, which in turn leads to deterioration of liver reserve. Moreover, a large proportion of HCC patients who underwent curative therapy died from progressive liver decompensation rather than recurrence of cancer. It had been proved that anti-viral therapy for hepatitis C virus (HCV)-related HCC patients could reduce the rate of tumor recurrence after surgical resection.
This is a prospective study to evaluate the efficacy of ETV therapy in chronic hepatitis B patients after receiving RFA therapy for HCC.
