Hepatitis B virus (HBV) infection is associated with many extrahepatic malignancies, but its association with and impact on ovarian cancer has not been examined. We therefore examined the prevalence of HBV infection among women with primary ovarian carcinoma in an endemic area, and whether this impacts the presentation and survival of these patients. In a retrospective study, we reviewed 523 patients presenting with primary ovarian cancer and known HBV status between 1 January 2006 and 31 December 2017. Patients were divided into HBV-positive and negative groups for the comparison of the patient characteristics and presentation, including staging and histological types, and short term (2 years) mortality from ovarian cancer. Among the 10.1% (53/523) patients screened positive for HBV, more of them presented with advanced staging at FIGO stage 3 or above (OR 1.378, 95% CI 1.063-1.787), although there were no significant differences in patient characteristics. Within 24 months from presentation, there were more deaths due to malignancy in the HBV-positive group (73.3% vs 44.2%, OR 1.659, 95% CI 1.135-2.425). On multivariate analysis after adjusting for nulliparity status, previous use of oestrogens, presence of metastases, histological type (epithelial or others) and grading (high grade or not), whether optimal debulking was performed, and chemotherapy, HBV infection was independently associated with increased death within 24 months of presentation (aOR 2.683, 95% CI 1.015-7.091). In conclusion, the findings of this study suggested an adverse effect of chronic HBV infection on survival within two years of presentation in patients with primary ovarian cancer.
