What Oncology Nurses Need to Know About Tumor Lysis Syndrome

Tumor lysis syndrome (TLS) is an oncologic emergency caused by massive tumor cell death with the release of large amounts of potassium, phosphate, and nucleic acids into systemic circulation. Nucleic acids break down to uric acid, leading to hyperuricemia in patients. This, in turn, leads to precipitates in the renal tubules, renal vasoconstriction, decreased renal flow, inflammation, and can potentially cause acute kidney injury.
