Yan PG, et al. - Researchers here surveyed the impact of preoperative hepatitis B virus levels on prognosis after primary and repeat hepatectomies for hepatocellular carcinoma patients. In this retrospective study, for HBV-related hepatocellular carcinoma patients, the levels of HBV DNA before hepatectomies were significant prognostic risk factors. These patients could be benefitted with surveillance of serum HBV DNA levels at multiple time points, rather than at a single time point, and antiviral therapy to suppress the virus to a low level.
