- W2160678466 abstract "We read with great interest the study by Yeh et al.1 on hepatitis B virus (HBV)-DNA level and basal core promoter A1762T/G1764A mutation in liver tissue independently predicting postoperative survival in hepatocellular carcinoma (HCC). According to the article, the amount of HBV-DNA in liver tissue and the presence of the basal core promoter mutation were two independent predictors for postoperative survival in HCC. The authors also found that a short-stretch pre-S deletion located between codons 107 and 141 was associated with a poorer postoperative prognosis. This study can be hailed as an original contribution in terms of predicting postoperative survival in HCC; however, we have some concerns about it. First, as is well known, evidence suggests that HBV genetic mutations contribute to the risk of HCC. Recent studies have shown that HBV genotype- or subgenotype-specific mutations, including C1653T in the EnhII region, T1753V, and the double mutant A1762T/G1764A in the BCP region, are independent risk factors for HCC.2 Another study has indicated that pre-S deletions, I68T in surface gene, T1762/A1764, and A1899 are independent risk factors for HCC.3 A recent meta-analysis revealed that the HBV pre-S mutations C1653T, T1753V, and A1762T/G1764A are associated with an increased risk of HCC. These mutations alone and in combination may be predictive of hepatocarcinogenesis.4 We wonder whether the other gene mutations correlated with HCC in HBV other than the basal core promoter A1762T/G1764A mutation (e.g., C1653T, T1753V, A1899) can independently predict postoperative survival in HCC. Second, it has not been determined whether hepatitis B e antigen (HBeAg) is associated with postresection survival in HCC. According to Sun et al.,5 HBeAg was associated with a higher risk of early recurrence and poorer survival in patients after curative resection of small HCC. However, Chen et al.3 indicated that HBeAg positivity is not a negative factor for resection in HCC patients and has no significant influence on postresection survival. Therefore, we wonder whether HBeAg was associated with postresection survival in HCC in the study by Yeh et al. Given that the serum samples used in the study had been stored in the serum bank, we think that the detection of HBeAg in both groups is convenient and has great significance. Finally, a study by Tomimaru et al.6 showed that histological assessment of the degree of fibrosis in noncancerous tissue is a unique prognostic factor for primary HCC without hepatitis B or C viral infection. If this is the case, then is histological assessment of the degree of fibrosis in noncancerous tissue one of the prognostic factors for HBV-related HCC as well?" @default.
