Clinical Characteristics and Outcome of Pediatric Oncology ICU Admissions

Abstract

Pediatric oncology patients admitted to the pediatric intensive care unit (PICU) represent a high-risk group due to the combined effects of malignancy, immunosuppression, and treatment-related complications. These patients frequently develop life-threatening conditions such as sepsis, respiratory failure, and multiorgan dysfunction, necessitating advanced critical care support. This review highlights the clinical characteristics, common indications for PICU admission, and major prognostic factors affecting Outcome in pediatric oncology patients. Evidence from recent studies indicates that mortality is closely related to the severity of acute illness, number of failed organ systems, and the need for organ support, including mechanical ventilation and vasopressors. Early PICU admission and timely interventions significantly improve survival, whereas delayed referral is associated with worse Outcome. Additionally, conventional scoring systems have limited predictive value in this population, emphasizing the need for oncology-specific prognostic tools. Advances in supportive care, multidisciplinary management, and risk stratification have contributed to improved short-term Outcome.
