Spectrum of liver disease and duck hepatitis B virus infection in a large series of chinese ducks with hepatocellular carcinoma
Agnes Duflot, Raj Mehrotra, Shun‐Zhang Yu, Luc Barraud, Christian Trepo, Lucyna Cova – 1 June 1995 – The striking difference in the geographical distribution of liver cancer in ducks raised the question of whether duck hepatitis B virus (DHBV), like mammalian hepadnaviruses, could be an oncogenic agent. Hepatocellular carcinomas (HCCs) have been found only in domestic ducks in Qidong, China, where hepatitis B virus infection and aflatoxin B1 (AFB1) are both risk factors and where a high frequency of human HCCs has been reported.
