Dinutuximab is a monoclonal antibody administered to patients with high-risk neuroblastoma, usually after an autologous stem cell transplant. Dinutuximab is associated with immune mediated and neurologic toxicities, but fatal adverse events are rare. A case is presented of high-risk neuroblastoma with development of encephalopathy shortly after the first course of dinutuximab.

This case underscores the difficulty in diagnosis of bone marrow failure disorders, as the presentation of disease can be inconsistent, complicated by complex and ever-expanding genetic etiologies. A patient who presents with bone marrow failure and pancreatic insufficiency raises the question of Shwachman-Diamond syndrome (SDS) or a new condition which resembles SDS.

Survival outcomes for osteosarcoma have plateaued since the 1980s, and patients with relapsed or refractory disease have a particularly dismal outcome. Treatment options for these patients are limited primarily due to the paucity of effective therapeutics. Immune therapies such as tumor vaccines and traditional antigen-targeted monoclonal antibodies have had limited success in solid tumors.

Oncolytic virotherapy has shown exciting promise for the treatment of many types of solid tumors. Pediatric sarcomas are an aggressive type of pediatric malignancy known to show limited responsiveness to current therapies, leading to unacceptably high morbidity and mortality. Oncolytic viruses have only recently been used for the treatment of this challenging cancer, and results have been encouraging.
