Nodular lymphocyte predominant Hodgkin lymphoma in children and adolescents - a comprehensive review of biology, clinical course and treatment options

Abstract

Nodular lymphocyte predominant Hodgkin lymphoma (nLPHL) is a unique variant of Hodgkin lymphoma with an overall good prognosis. It is conspicuously different from classical Hodgkin lymphoma (cHL) and is now recognized as distinctive form of B cell lymphoma. Although it has an indolent clinical course, it has a propensity for multiple and often late relapses. Although the majority of children present with early stage disease and without B symptoms, treatment strategy has, until recently, been identical to that used for cHL. This approach is excessively toxic as it predisposes these children and adolescents to serious late effects including end organ damage to heart, gonads, lungs, thyroid and second malignant neoplasms. The aim of this article is to review the published literature on the treatment outcomes of nLPHL in affected children and adolescents, and discuss the options for treatment including surgery, chemotherapy, radiotherapy and targeted anti-CD 20 antibody therapy. © 2012 Blackwell Publishing Ltd.
