P KZN NBLA X PX X LDH X FERRITIN

LDH and ferritin are strongly prognostic in NB, overall and within high‐risk NB patients treated post‐2009 with modern therapy. LDH and ferritin show promise for (a) identifying ultra‐high‐risk; (b) refining risk stratification; and (c) clinical utility in low‐/middle‐income countries. Routine collection of LDH and ferritin should be reinitiated for evolving NB risk stratification.
