This syndrome commonly occurs after treatment of high-grade bulky NHLs because of their exquisite sensitivity to therapy, which is caused by their high proliferative capacity. Tumor lysis syndrome is characterized by hyperuricemia, hyperkalemia, hyperphosphatemia, hypocalcemia, and renal failure. Death from cardiac asystole can occur from hyperkalemia.

Measures to prevent this complication include aggressive hydration, allopurinol administration, and urine alkalinization. Frequent monitoring of input and output, electrolytes, uric acid, and creatinine is necessary. Dialysis is sometimes required.
