Abstract
Hepatitis B virus (HBV) DNA integration occurs during the reverse transcription process of HBV replication, which develops in the early stages of HBV infection and accompanies the entire disease course. The integration of HBV DNA is detrimental to the attainment of clinical cure goals and also raises the risk of developing liver cancer. Theoretically, nucleos(t)ide analogs can reduce the synthesis of new double-stranded linear DNA, but there is no clearance function for hepatocytes that have already integrated HBV. Therefore, patients with serum HBV DNA-negative conversions still have the risk of developing liver cancer. As an immunomodulatory drug, interferon can not only inhibit viral replication but also inhibit or even eliminate existing clonally amplified hepatocytes carrying integrated HBV DNA fragments. However, there are currently few studies on the effects of nucleos(t)ide analogues and interferon therapy on HBV DNA integration. Thus, large-scale clinical studies are urgently needed for further clarification.
