In the induction phase, all patients with stage 4 neuroblastoma and those with stage 4s MYCN-amplified neuroblastoma will be randomised (R3) to Rapid COJEC or modified N7; localised patients receive Rapid COJEC (Rapid COJEC is given with G-CSF support based on the results of the R0 randomisation running between 2002 and 2005).
