About

Chronic hepatitis B seriously endangers the health of our people, especially the occurrence of HCC, which brings huge economic burden and life threat to our people. 84% - 92% of HCC in China is related to chronic HBV infection. How to further reduce the risk of liver cancer is an urgent problem to be solved in clinical research and an important direction. Although NAs treatment can make patients achieve the negative transformation of virus, it can not effectively reduce the level of virus antigen, and it also lacks the ability to improve the immune clearance of virus. As a result, the incidence of liver cancer in patients with long-term NA treatment is still 4.5% - 10.5%, and the incidence of HCC in patients with hypoviremia in Na treatment is higher. In current clinical practice, nearly 1 / 3 of patients treated with NAs can not reach the detection line of highly sensitive reagent. It is an important measure to make the patients with hypoviremia and inactive low virus replication treated by NAs below the detection line of highly sensitive reagent and further reduce the risk of HCC. However, it is still not enough to minimize the risk of HCC to achieve a complete viral response only through NA treatment. The long-term follow-up showed that the incidence of HBsAg disappeared by only 2.0% - 0.0% regardless of the long-term treatment of HBsAg. Therefore, the most important measure to minimize the occurrence of HCC is to optimize the treatment of NA treated patients with low virus replication and inactive patients with low virus replication to achieve complete virus response and clinical cure. The purpose of this study is to explore the optimal treatment scheme for chronic hepatitis B NA treated patients with hypoviremia and natural low virus replication patients to significantly reduce the risk of HCC.

Full description

Chronic hepatitis B seriously endangers the health of our people, especially the occurrence of liver cancer, which brings huge economic burden and life threat to our people. 84% - 92% of hepatocellular carcinoma (HCC) in China is related to chronic HBV infection. How to further reduce the risk of liver cancer is an urgent problem to be solved in clinical research and an important direction. Although NAs treatment can make patients achieve the negative transformation of virus, it can not effectively reduce the level of virus antigen, and it also lacks the ability to improve the immune clearance of virus. As a result, the incidence of liver cancer in patients with long-term NA treatment is still 4.5% - 10.5%, and the incidence of HCC in patients with hypoviremia in Na treatment is higher. In current clinical practice, nearly 1 / 3 of patients treated with NAs can not reach the detection line of highly sensitive reagent. It is an important measure to make the patients with hypoviremia and inactive low virus replication treated by NAs below the detection line of highly sensitive reagent and further reduce the risk of HCC. However, it is still not enough to minimize the risk of HCC to achieve a complete viral response only through NA treatment.
