Summary
Medical scientists want to find better ways to treat neuroblastoma and to find ways to
prevent the tumor from growing back. To do this, they need more information about the
characteristics of neuroblastoma cells. Therefore, they want to study samples of
neuroblastoma tissues and neuroblastoma and normal cells in the blood and bone marrow
that may be related to the growth of neuroblastoma cells. Doctors and other medical
scientists also want to find better ways to detect and measure neuroblastoma to improve
the ability to follow the response of tumor cells to therapy.
