Molecular Characterization of Neuroblastic Tumor: Correlation With Clinical Outcome

The purpose of this study is to find out the genetic and biochemical makeup of your neuroblastic tumor, which influences its aggressiveness and the suitable therapy. These research studies include surface marker analysis, cytogenetics, cancer genes,genome sequencing, tumor growth-related genes and tumor growth in test tubes. Your blood, marrow, and hematopoietic stem cell samples will also be tested for tumors or leukemia cells, and your serum tested for anti-tumor antibodies.
