To correlate early HBV-DNA suppression by antiviral treatment with posthepatectomy long-term survivals in patients with HBV-related hepatocellular carcinoma (HCC).
A retrospective study was conducted on patients with a baseline HBV-DNA load of >2,000 IU/ml. The cumulative rates of HBV-DNA undetectability at weeks 24 and 48, as well as long-term tumor recurrence and overall survivals were determined.
Of 1,040 patients with a high baseline HBV-DNA load, 865 patients received antiviral treatment. At a median follow-up of 42 months, 616 patients (59.2 %) had developed HCC recurrence and 482 patients (46.3 %) had died. The median time to recurrence was 25 months. In patients who received antiviral treatment, the cumulative rates of HBV-DNA undetectability (<200 IU/ml) were 54.3 and 88.1 % at weeks 24 and 48, respectively. There was no significant difference between the two groups of patients who received antiviral treatment or not for disease-free survival. On multivariate analyses, tumor size >5 cm, blood transfusion, surgical margin <1 cm, presence of satellite nodules, presence of portal vein tumor thrombus and high Ishak inflammation score were significant risk factors of HCC recurrence. Also, tumor size >5 cm, surgical margin <1 cm, presence of satellite nodules, presence of portal vein tumor thrombus and high Ishak fibrosis score were significant factors associated with poor postoperative overall survival. On the other hand, an undetectable HBV-DNA level before week 24 was a significant protective factor of disease-free survival and overall survival.
Early HBV-DNA suppression with antiviral treatment improved prognosis of patients with HBV-related HCC.
