Abstract

We reported two infantile cases of mediastinal neuroblastoma with life-threatening tracheal obstructions presenting as oncologic emergencies that were successfully treated per tentative risk classification using serum-based MYCN gene amplification (MNA) analysis. Tentative risk stratification based on age, tumour location and serum-based MNA status may be useful in patients with neuroblastoma presenting as oncologic emergencies who require urgent therapy stratification but for whom tumor-based molecular diagnoses cannot be established.
