title: Oncological emergencies: clinical importance and principles of management.
abstract: Oncological emergencies are common conditions associated with significant morbidity and mortality. Delay in diagnosis and treatment can result in unfavourable outcomes. Cancer itself, cancer-related hormones or cytokines, or treatment effects can cause emergency problems. Febrile neutropaenia, frequently associated with chemotherapy, can lead to life-threatening conditions. Treatment requires systematic evaluation and early empirical antibiotics. Hypercalcaemia of malignancy is the most common metabolic emergency in cancer patients. Non-specific clinical features may cause delay in diagnosis and increase morbidity and mortality. Treatment includes active fluid resuscitation, diuretics and intravenous bisphosphonates. Superior vena cava syndrome is usually caused by external compression. Computerised tomography is useful to confirm diagnosis, evaluate the extent of disease and guide invasive tissue diagnosis. Treatment and prognosis depend on the underlying malignancies. Spinal cord compression is a true emergency due to risk of permanent neurological impairment. Localised back pain is the most common presenting symptom while late presentation of neurological deficit is associated with irreversible outcomes. Magnetic resonance imaging is the investigation of choice. Treatment includes corticosteroids, radiotherapy and/or decompressive surgery.
