Abstract
Objective: to investigate HBV BCP/PC mutations were associated with liver cirrhosis (LC) and hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) patients with HCC at Vietnam National Cancer Hospital, Hanoi. Methods: The BCP/PC mutations were significantly associated with LC and HCC in 40 chronic hepatitis B patients with HCC at Vietnam National Cancer Hospital, Hanoi, from January 2017 to December 2019 were investigated by direct sequencing on 3130XL Genetic analyzer ABI. Results: Seven mutations in the BCP/PC region associated with cirrhosis in chronic hepatitis B patients with HCC include A1726C, A1727T, C1730G/A, C1766T, T1768A, C1773T and C1799G. Eight mutations in the BCP/PC region associated with HCC in CHB patients with HCC include T1753V, A1762T, G1764A, A1846T, G1896A and G1899A, A1762T/G1764A và A1762T/G1764A + T1753V (C/A/G/del). The frequency of mutations varies depending on the genotype, in general, the frequency of mutations associated with cirrhosis and HCC is higher in genotype B than in genotype C. Conclusions: Seven mutations in the BCP/PC region associated with cirrhosis in CHB patients with HCC include A1726C, A1727T, C1730G/A, C1766T, T1768A, C1773T and C1799G. Eight mutations in the BCP/PC region associated with HCC in CHB patients with HCC include T1753V, A1762T, G1764A, A1846T, G1896A and G1899A, A1762T/G1764A và A1762T/G1764A + T1753V (C/A/G/del).
