    Abstract: Background and Aims: Prophylactic antiviral therapy was recommended to prevent HBV reactivation for lymphoma patients with resolved HBV infection who received rituximab-containing chemotherapy. This study sought to identify high-risk patients by measuring baseline levels of serum anti-HBc and anti-HBs. Methods: We prospectively followed the HBV DNA levels of 197 lymphoma patients with resolved HBV infection who received rituximab-CHOP (cyclophosphamide, doxorubicin, vincristine, prednisolone)-based chemotherapy and started antiviral therapy upon HBV reactivation, defined as a greater than 10-fold increase in HBV DNA compared with previous nadir levels (www.clinicaltrial.gov identifier: NCT 00931229). Anti-HBc and anti-HBs levels were measured by double antigen sandwich immunoassay and enzyme immunoassay. Receiver operating characteristic curve analysis was used to determine optimal baseline anti-HBc/anti-HBs levels for prediction of HBV reactivation. Results: The median baseline anti-HBc and anti-HBs levels were 4.25 IU/mL (range 0.23–191.86) and 72.3 mIU/mL (range 0–12513.5) for the 192 patients with enough serum samples for analysis. High anti-HBc (>=6.41 IU/mL) and low anti-HBs (<56.48 mIU/mL) were significantly associated with high risk of HBV reactivation (odds ratio 5.42, and 8.87, respectively, p < 0.001). The cumulative incidence of HBV reactivation at 15 months was 45.8% (95% CI 27.3–64.2) for patients with both high anti-HBc and low anti-HBs at baseline (36 of 192 patients) and 3.0% – 9.6% in other patients (p < 0.001). HBV reactivation, when considered as a time-dependent covariate, independently predicted inferior overall survival (HR 2.41, 95% C.I. 1.15–5.05, p = 0.02). Conclusions: Baseline anti-HBc/anti-HBs levels may predict HBV reactivation. Efficacy of prophylactic antiviral therapy for the long-term clinical outcome should be explored.
