Clinicopathological differences between hepatitis B viral genotype B- and C-related resectable hepatocellular carcinoma.
Clinical and pathogenic differences exist between hepatitis B viral (HBV) genotypes B and C, and genotype C has a higher risk of hepatocellular carcinoma (HCC) development than genotype B. The aim of this study was to investigate whether HBV genotypes B and C influence the clinicopathological features of patients with resectable HCC. Stored serum samples from 193 patients with resectable HBV-related HCC were tested for HBV genotypes by a molecular method. Of 193 patients undergoing resection of HCC, 107 (55%) and 86 (45%) were infected with genotypes B and C, respectively. Compared with genotype C patients, genotype B patients were less likely to be associated with liver cirrhosis (33%vs 51%, P = 0.01). Pathologically, genotype B patients had a higher rate of solitary tumour (94%vs 86%, P = 0.048) and more satellite nodules (22%vs 12%, P = 0.05) than genotype C patients. Our results indicate that genotype B-related HCC is less associated with liver cirrhosis and has a higher frequency of solitary tumour as well as more satellite nodules than genotype C-related HCC. These characteristics may contribute to the recurrence patterns and prognosis of HBV-related HCC in patients with genotype B or C infection.
