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.
Causes
Life Threatening Causes
Tumor lysis syndrome resulting from any cause is a life threatening condition and needs immediate management.

- Burkitt's lymphoma
- Acute myeloid leukemia
- Acute lymphoblastic leukemia
