[Neuroblastoma: diagnosis and therapy].

Prognosis of neuroblastoma is primarily dependent on the stage of disease. While stages 1 to 3 show a survival rate of 94 to 66%, stage 4 has a survival rate below 20%. The most important prognostic factor is the extent of disease. Age, LDH, resectability of primary tumor, cytologic and molecular parameters are defined to have a prognostic impact as well. A stage- and risk-adapted therapy of neuroblastoma needs a thorough assessment of all these factors.
