Preventing primary liver cancer: how well are we faring towards a national hepatitis B strategy?

In reply: We agree with Awofeso that prisoners and Indigenous people have an increased risk of developing chronic hepatitis B. However, as no large-scale population-based studies of hepatitis B prevalence have been published in Australia, estimates of the risk vary widely.1 A national hepatitis B strategy may provide additional impetus for obtaining high-quality data. We also concur that modifiable behavioural factors may play a role in the age of hepatocellular carcinoma diagnosis, but differences in clinical course between Asian and white Australians,2 and the specific viral genotypes prevalent in Asia,3 are likely to be more important.
