Efficacy of entecavir versus tenofovir in preventing hepatocellular carcinoma in patients with chronic hepatitis B with maintained virologic response.

In patients showing maintained virologic response, no difference in the risk of HCC between entecavir and tenofovir was observed. This indicates entecavir might be as effective as tenofovir in the prevention of HCC among those patients and suggest that a change in therapy in anticipation of further reducing the risk of HCC might not be necessary for patients receiving entecavir and showing virologic response.
