Prevalence of hepatocarcinoma-related hepatitis B virus mutants in patients in grey zone of treatment

Figure 2 Analysis of basal core promoter /precore/core mutants related with the e-antigen negative status. A: Prevalence of individual mutations of the in the 3 most frequent HBV genotypes analyzed; B: Frequency of coexistence of more than one BCP/precore/core mutants; and C: Frequency of the most common combination of mutations in the different genotypes. The frequency calculation was performed including only the 23 patients with precore/core sequences data, not in on intention to treat basis. BCP: Basal core promoter; HBV: Hepatitis B virus; A: HBV-A; D: HBV-D; E: HBV-E.
