Pediatric Non Hodgkin’s Lymphomas
Journal Title: Iranian Journal of Blood and Cancer - Year 2010, Vol 2, Issue 3
Abstract
Pediatric non-Hodgkin lymphoma (NHL) is a diverse collection of diseases, and results from malignant proliferation of lymphoid cells and immune system. NHL involves throughout the body, but bone and primary central nervous system (CNS) lymphomas are its rare presentations. The incidence of NHL in childhood differs according to age and geographic area, but overall constitutes 8–10% of all malignancies in children between 5–19 years of age. The preferred pathologic and molecular biology classification for NHL is based on currently recognized histologic (morphologic), immunophenotypic, and genetic features, and their clinical presentation and course. The clinical manifestations of NHL in children depend on pathological subtype and primary sites of disease. Abdomen and mediastinum are the most frequent primary sites of involvement. Most centers use st. Jude staging system and diagnostic workup. Most patients present with advanced stage and systemic disease. According to pathophysiology of childhood NHL, treatment strategy is based on extent of dissemination and requires attention to emergent complications. Modern treatments have caused dramatic improvement in childhood NHL. We need well conducted international studies in all parts of the world to increase our knowledge to acieve better outcome and prevent late effects in children.
