Treatment of Tumor Lysis Syndrome

• Avoid IV contrast and NSAIDs; treat hyperK, hyperPO4, and only symptomatic hypoCa • Allopurinol + aggressive IV hydration ± diuretics to ↑ UOP for goal 80–100 cc/h • Rasburicase (0.1–0.2 mg/kg or 6 mg IV fixed dose) for ↑↑ uric acid esp. in aggressive malig (JCO 2003;21:4402; Acta Haem 2006;115:35). Avoid in G6PD def (hemolytic anemia). Consider G6PD testing in Jehovah’s Witnesses especially if Black (12% prevalence). • Hemodialysis may be necessary; early renal consultation for renal insufficiency or ARF

  • consider intensive care unit (ICU) transfer, depending on clinical status and degree of metabolic derangement (Note: TLS implies a highly responsive tumor and initial response to therapy.)

  • lab tests every 4 to 6 hours and treatment of electrolyte abnormalities

  • cardiac monitoring

  • intravenous fluids (IVF)

  • rasburicase for significant hyperuricemia, particularly if renal dysfunction is a concern

  • dialysis as a last resort

The following flowchart is helpful for the initial assessment and management of TLS:
