Notas

T-ALL hyperleukocytosis + TLS is high-frequency (T-ALL median WBC at diagnosis ~50-100K). Per NCCN: rasburicase IV 0.2 mg/kg + IV hydration + electrolyte management before steroid pre-phase / induction. Per CALGB-10403: stepwise cytoreduction with steroid pre-phase to mitigate acute TLS. Direction HOLD; priority 10 (matches AML emergency RF). STUB — requires clinical co-lead signoff.
