Definition

Tumor lysis syndrome (TLS) is a group of metabolic abnormalities resulting from rapid lysis of malignant cells and massive release of cell breakdown products into blood. It is a life threatening condition and an oncologic emergency. Metabolic complications include hyperkalemia, hyperphosphatemia, hyperuricemia, hypocalcemia and hyperuricosuria.
