Relationship between hepatitis B virus genotyping and primary hepatocellular carcinoma of 182 patients / 公共卫生与预防医学

ABSTRACT

Objective To analyze the relationship between hepatitis B virus genotyping and primary liver cancer (PHC) in Wuhan, and to provide a theoretical basis for the early prevention and diagnosis of PHC. Methods Patients with chronic hepatitis B (CHB) from Wuhan Sub-heart General Hospital for treatment from February 2020 to February 2021 were selected and divided into PHC group (182 cases) and control group (189 cases) according to whether they were complicated with primary liver cancer. 5ml of fasting elbow venous blood was taken from all subjects at admission. HBV genotyping was determined by real-time fluorescence quantitative PCR. The DNA of CHB virus was determined by fluorescence probe hybridization and PCR amplification, and genotyping and drug-resistant mutation points were detected according to the product sequencing analysis. Spearman linear correlation analysis was used to analyze the correlation between genotyping and mutation rate of PHC patients. Results The proportion of C genotype in PHC group was significantly higher than that in non-PHC group (P0.05). The proportion of HEPATITIS B virus mutation in PHC group (114/182) was significantly higher than that in control group (84/189) (χ2=12.331, P0.05). The proportion of HBV C mutant in PHC group was significantly higher than that in control group (P1=0.349, r2=0.305, P<0.05). Conclusion The HBV genotype of PHC patients is mainly TYPE C, and has a high mutation rate of C genotype. It can be used for diagnosis of PHC by detecting the genotyping of CHB and mutation rate of C genotype in clinic.
