BackgroundTo investigate the clinicopathologic characteristics of patients with both hepatitis B virus-surface antigen and hepatitis C virus antibody negative hepatocellular carcinoma (non-B non-C HCC [NBNC-HCC]) and examine the impact of occult hepatitis BÂ virus infection (OBI) on patients' survival.MethodsAll patients with OBI were identified from a database of patients with NBNC-HCC who underwent surgical resection between January 1, 2006, and December 31, 2008. Their clinicopathologic and survival characteristics were compared with NBNC-HCC patients without OBI.ResultsOut of the 86 NBNC-HCC patients, 59 patients (68.6%) with OBI. A higher prevalence of hepatitis B core antigen positive rate, low platelet count, portal hypertension, and liver cirrhosis were observed in NBNC-HCC patients with OBI. The 1- and 3-y recurrence free survival rates were 66% and 25% in OBI group and 89% and 70% in the no OBI group, respectively (PÂ <Â 0.001). The 1-, 3-, and 5-y overall survival rates were 86%, 55%, and 51% in OBI group and 93%, 85%, and 66% in no OBI group, respectively (PÂ =Â 0.112). Multivariate analysis revealed that OBI (hazard ratio [HR]Â =Â 2.122; 95% confidence interval [CI], 1.086-4.149; PÂ =Â 0.028), liver cirrhosis (HRÂ =Â 2.411; 95% CI, 1.337-4.345; PÂ =Â 0.003), and vascular invasion (HRÂ =Â 5.858; 95% CI, 2.799-12.261; PÂ <Â 0.001) were independent poor prognostic factors for recurrence free survival of patients with NBNC-HCC.ConclusionsNBNC-HCC patients with OBI had a poorer prognosis. OBI can be a useful predictor for recurrence in patients with NBNC-HCC after surgery.
