Summary
Brief summary (as posted)
Apart from brain tumors, Neuroblastoma is the most common solid tumor during childhood. About 50% of the cases present at diagnosis with factors of bad prognosis. During the last two decades, despite increased therapeutic intensity during induction and consolidation of high-risk neuroblastomas, the 5 year overall survival of high risk neuroblastoma remains in between 30 to 40% depending on studies. Besides strategies of high-dose chemotherapy followed by autologous transplantation of hematopoietic stem cells, and differentiating molecules (retinoids), immunotherapy will become one of the leading anti-neuroblastoma targeted therapy. No therapeutic strategies or molecules obtained such gains of survival ever before. Studying the immune system of children with neuroblastoma at diagnosis and during their treatment will help us to determine when we should test active or passive immunotherapy strategies. Moreover, this study would allow us to specify the cause of tumor immune tolerance in neuroblastoma, on which we have few data in comparison to adult tumors. This will be a multicentric, pilot, prospective, open, study that will not require unusual diagnostic interventions. This study will be transversal (all neuroblastoma stages included) in order to determine comparative criteria between low and high risk neuroblastoma. It will also be longitudinal (from diagnosis to post-treatment follow-up) in order to specify evolutionary aspects of immunity under radio-chemotherapy and retinoic acid therapy. Immunological analyses will be done on blood, bone marrow and tumor samples, at diagnosis, and during the treatment of children diagnosed for neuroblastoma (up to 3 time points). These types of samples are routinely done during conventional neuroblastoma treatment.
