The aim of current study was to elucidate the prevalence of HBV and HCV among large population of solid cancers and lymphoma and to compare them with large number of control group. Patients and Methods: Between 2000 and 2014, 8322 cancer patients who were admitted to Oncology Departments were evaluated retrospectively and 3890 patients in whom hepatitis serology were available were included in this study. Their results were compared with control group that consisted of 96,000 subjects. Results: In control groups, hepatitis B surface antigen (HBsAg) positivity rate was 3.3% and anti-HCV positivity rate was 0.84%. In cancer patients, HBsAg positivity rate was 3.65% and anti-HCV positivity rate was 1.2%. Neither HBsAg positivity rate nor anti-HCV positivity rate was statistically significant between groups (P = 0.12 and P = 0.09, respectively). HBsAg positivity rates of head and neck cancer (5.88%; P = 0.02), rectum (5.6%; P = 0.025), and gastric and esophagus cancer (5.88%; P = 0.025) were significantly higher than control groups. Anti-HCV positivity rate (2.5%; P = 0.0016) was significantly higher in lung cancer when compared with control group. Conclusion: The current study elucidated the prevalence of HBV and HCV among large population of solid cancers and lymphoma and we showed that hepatitis B and C positivity rates are significantly increased in certain solid tumors. Our findings should also be clarified with large prospective studies.
