Cancers Attributable to Infectious Agents in Nigeria: 2012-2014

Abstract 60Background:Infections by certain viruses, bacteria, and parasites have been identified as risk factors for some cancers. In 2008, there were 12.7 million new cancer cases worldwide. About 2 million of these new cases were attributable to infections, which represent 16.1% of new cancer cases. The majority of these cancers occurred in less-developed regions of the world, where the Population Attributable Fraction (PAF) was estimated to be 23%. We carried out this study to evaluate the numbers of cancers in Nigeria from 2012-2014 that are attributable to infections using data from Population Based Cancer Registries (PBCR) in Nigeria.Methods:We considered cancers associated with Epstein-Barr virus (EBV), Human Papilloma Virus (HPV), Hepatitis B and C Virus (HBV/HCV), Human Immunodeficiency Virus and Human Herpes Virus 8 (HIV/HHV8), Helicobacter pylori, and Schistosoma haematobium that have been classified as oncogenic by IARC.
