Risk stratification of high-risk metastatic neuroblastoma: A report from the HR-NBL-1/SIOPEN study

Original language description

BackgroundRisk stratification is crucial to treatment decision-making in neuroblastoma. This study aimed to explore factors present at diagnosis affecting outcome in patients aged18 months with metastatic neuroblastoma and to develop a simple risk score for prognostication. ProcedureData were derived from the European high-risk neuroblastoma 1 (HR-NBL1)/International Society for Paediatric Oncology European Neuroblastoma (SIOPEN) trial with analysis restricted to patients aged 18 months with metastatic disease and treated prior to the introduction of immunotherapy. Primary endpoint was 5-year event-free survival (EFS). Prognostic factors assessed were sex, age, tumour MYCN amplification (MNA) status, serum lactate dehydrogenase (LDH)/ferritin, primary tumour and metastatic sites. Factors significant in univariate analysis were incorporated into a multi-variable model and an additive scoring system developed based on estimated log-cumulative hazard ratios. ResultsThe cohort included 1053 patients with median follow-up 5.5years and EFS 271%. In univariate analyses, age; serum LDH and ferritin; involvement of bone marrow, bone, liver or lung; and &gt;1 metastatic system/compartment were associated with worse EFS. Tumour MNA was not associated with worse EFS. A multi-variable model and risk score incorporating age (&gt;5 years, 2 points), serum LDH (&gt;1250U/L, 1 point) and number of metastatic systems (&gt;1, 2 points) were developed. EFS was significantly correlated with risk score: EFS 52 +/- 9% for score=0versus 6 +/- 3% for score=5 (P&lt;0.0001). ConclusionsA simple score can identify an ultra-high risk (UHR) cohort (score=5) comprising 8% of patients with 5-year EFS&lt;10%. These patients appear not to benefit from induction therapy and could potentially be directed earlier to alternative experimental therapies in future trials.
