Overview
In medicine (oncology and hematology), tumor lysis syndrome (TLS) is a group of metabolic complications that can occur after treatment of cancer, usually lymphomas and leukemias, and sometimes even without treatment. These complications are caused by the break-down products of dying cancer cells and include hyperkalemia, hyperphosphatemia, hyperuricemia, hypocalcemia, and acute renal failure.
Classification
Tumor lysis syndrome (TLS) may be classified according to the 1993 Hande-Garrow classification system into two groups: laboratory tumor lysis syndrome (LTLS) and clinical tumor lysis syndrome (CTLS).[1]
Pathophysiology
Development of tumor lysis syndrome is the result of initiation of chemotherapy or radiotherapy in cancer patients.
