[Epidemiology of classical Hodgkin lymphoma].

Abstract

EPIDEMIOLOGY OF CLASSICAL HODGKIN LYMPHOMA. Classical Hodgkin lymphoma is a rare neoplasia but represents one of the most common cancers in adults younger than 40 years old. Epidemiology of Hodgkin lymphoma remains fascinating with specific incidence patterns depending of age, socio-economic status, histological subtypes and Epstein-Barr virus (EBV) tumor status. These findings are in favor of several diseases with different pathogenesis. A better understanding of biological specificities of some Hodgkin lymphoma subgroups such as those presenting by older patients might be helpful to improve treatment strategies and outcome. Currently, no causal agent has been identified. Some risk factors are described, especially genetic ones, but no specific screening or prevention procedure are currently indicated.
