Children with cancer are at increased risk for life-threatening complications either due to their malignancy or its treatment. Emergencies can occur at any time during the course of childs malignant disease. Th e causes underlying most emergencies that occur in the fi eld of pediatric oncology fall into four main etiologic categories: metabolic, hematologic, infectious and mechanical emergencies. Many metabolic and endocrinologic problems can potentially occur in children with cancer: tumor lysis syndrome, hypercalcemia, hyperphosphatemia, syndrome of inappropriate secretion of antidiuretic hormone, hyponatremia, hypoglycemia, adrenal failure, lactic acidosis, and hyperamoniemia. Hematologic abnormalities that require emergency treatment result from either abnormal hematopoiesis (hyperleukocytosis, anemia, thrombocytopenia, neutropenia, and pancytopenia) or coagulopathy (hemorrhage and thromboembolism). Infectious emergencies include serious infections with bacteria, parasites, mycoplasmata, viruses, and/or fungi, particularly during child's periods of prolonged neutropenia. Pneumonitis, pancreatitis, hemorrhagic cystitis, enterocolitis, and tissue necrosis due to the extravasation of cytotoxic agents represent severe infl ammatory states that can occur. Mechanical emergencies refer to acute events that result from direct compression, obstruction, or displacement of vital structures by a malignant process. Th ese emergencies are conveniently classifi ed according to the organ system aff ected. Respiratory (airway obstruction), cardiovascular (superior vena cava syndrome, cardiac tamponade), neurologic (spinal cord compression, increased intracranial pressure, and seizures), gastrointestinal (obstruction, pseudo-obstruction, and ileus), and urologic (urinary obstruction) mechanical emergencies require immediate medical attention. Children with cancer experience a broad variety of critical illnesses related to both disease and therapy. Prompt recognition, evaluation, and treatment of these serious events are important to reduce morbidity and mortality in pediatric cancer patients.
