Ground-Breaking Study Finds Antiviral Treatment Does Reduce Cancer Risk
For the first time, an authoritative study has found that antiviral treatment appears to reduce the risk of hepatitis B virus (HBV)-related liver cancer. Even though treated patients had more liver damage, their cancer rates were similar to untreated, healthier patients.
Researchers from the U.S. Centers for Disease Control and Prevention examined the health records of 2,671 hepatitis B patients treated at four health centers across the U.S. between 1992 and 2011. Half of the patients were Asian-American and about 31% (820) had been treated with antivirals. The treated patients tended to have more liver damage, were older, male and less likely to be Asian-American than untreated patients in the study.
Researchers, reporting in the June issue of the journal ofClinical Gastroenterology and Hepatology, found that 67 (3%) of the 2,671 patients developed liver cancer over the study period. Twenty of the 820 patients treated with antivirals developed cancer, compared to 47 of the 1,851 untreated patients.
Treated patients with viral loads less than 20,000 IU/mL had a significantly lower risk of cancer than untreated patients with similarly low viral loads.
Antivirals appeared to confer some protection against liver cancer even in patients with fibrosis (liver inflammation) and cirrhosis (liver scarring), suggesting that viral loads may be the primary culprit behind liver cancer. By suppressing viral load, liver cancer was avoided in many of these high-risk patients with serious liver damage.
Researchers wrote, “…We found that antiviral treatment had a beneficial effect across a spectrum of viral load levels (and disease severity.)”

Sequential Treatment of Antivirals Followed by Interferon Spurs HBeAg Seroconversion
Chinese researchers found that hepatitis B “e” antigen (HBeAg)-positive patients who were treated first with the antiviral entecavir (Baraclude) and then with pegylated interferon achieve a higher rate of HBeAg seroconversion (loss of HBeAg and development of “e” antibodies) than patients treated with only entecavir.
