Neuroblastoma is the most common extracranial tumor derived from neural crest cells in childhood, and treatment of high-risk neuroblastoma is a difficulty in oncology field. The discovery of new treatment strategies to treat pediatric patients with high-risk neuroblastoma is important. Dinutuximab (ch14.18; Unituxin), a chimeric human-mouse monoclonal antibody, is approved by Food and Drug Administration in 2015 to be used specifically in the treatment of high-risk neuroblastoma. It binds the disialoganglioside (GD2) antigen on the surface of neuroblastoma cells and induces lysis of GD2-expressed neuroblastoma cells via antibody-dependent cell-mediated cytotoxicity and complement-dependent cytotoxicity. To enhance its activity, it is used with a combination of granulocyte-macrophage colony-stimulating factor, interleukin 2, and 13-cis-retinoic acid. In this review, we discuss the use of dinutuximab in the …
