Participants in this study are diagnosed or in the process of being diagnosed with neuroblastoma. While the diagnosis is being confirmed, this study would like to collect samples of a participant¿s tumor, blood and/or bone marrow to learn more about neuroblastoma. In addition this study is asking for permission to use some of the tumor tissue that is not needed for diagnosis for some specialized laboratory tests. These studies will only be done if the diagnosis of neuroblastoma is confirmed. Samples of the neuroblastoma tumor, bone marrow and/or blood will be sent to tumor banks located at Children¿s Hospital of Philadelphia, Children¿s Hospital Los Angeles, and the Biopathology Center (BPC) in Columbus, Ohio.
