Notes

Per NCCN Burkitt v.X.2025 §BURK-A: rasburicase mandatory for Burkitt pre-cycle-1; allopurinol insufficient for high-risk. ESMO-Burkitt 2024 echoes: rasburicase 0.2 mg/kg IV daily ×3-5 days, IV hydration 3 L/m²/day. Burkitt has highest TLS incidence among lymphomas (>30% high-risk). Direction HOLD on regimen start until uric acid <7.5, potassium <5.0, phosphate <4.5, creatinine baseline restored. Priority 10. Note this is a Burkitt-specific complement to RF-UNIVERSAL-TLS-RISK (which is intensify, surfaces supportive care without holding); this disease- specific HOLD is needed because Burkitt cycle 1 reduction-phase (COP/cyclophosphamide-vincristine-prednisone) sits between universal TLS-prophylaxis and definitive induction. STUB — requires clinical co-lead signoff.
