Recent Updates on Pediatric Oncological Emergencies and Their Management

Pediatric oncological emergencies are acute, life-threatening complications arising from malignancies or their treatment. Prompt recognition and intervention are essential to prevent significant morbidity and mortality. Pediatric oncological emergencies are categorized as metabolic, structural, hematological, or treatment-related. Structural emergencies include superior mediastinal syndrome, spinal cord compression, and raised intracranial pressure. Metabolic complications such as tumor lysis syndrome (TLS) and hypercalcemia are frequent, with TLS most common in leukemias and high-grade lymphomas. Hematological crises, hyperleukocytosis with leukostasis, and severe cytopenias may result in bleeding or infections. Treatment-related complications like febrile neutropenia and neutropenic enterocolitis (NEC) add further challenges. Effective management requires a multidisciplinary approach that combines early diagnosis, vigilant monitoring, supportive measures, and disease-directed therapy. Recent progress in risk stratification, early warning systems, and intensive supportive care has improved the ability to anticipate and mitigate these crises. Novel diagnostic tools, including point-of-care ultrasonography (POCUS) and laboratory markers, allow for faster identification of high-risk patients, while updated management guidelines provide evidence-based strategies for intervention. This review highlights novel insights and recent updates in the recognition and management of pediatric oncological emergencies.
