Neuroblastoma - Biomarkers in Tumor Tissue Samples From Patients With Newly Diagnosed Neuroblastoma or Ganglioneuroblastoma

This research trial studies biomarkers in tumor tissue samples from patients with newly diagnosed neuroblastoma or ganglioneuroblastoma. Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer.
