Abstract
Electrolyte imbalances are common in patients with cancer. They may arise from tumor- or treatment-related factors or other causes. These imbalances can lead to life-threatening oncologic emergencies, such as tumor lysis syndrome, syndrome of inappropriate antidiuretic hormone secretion, and hypercalcemia of malignancy. Early recognition and management are crucial to prevent serious complications and improve patient outcomes. Advanced practice providers must be aware of the symptoms in order to incorporate preventive measures and manage these abnormalities appropriately. This article will review the current evidence-based literature on electrolyte abnormalities and emergencies associated with electrolytes in the care of oncology patients.
