Rapid cytoreduction in childhood leukemic hyperleukocytosis by conservative therapy.
Childhood leukemic hyperleukocytosis poses a serious threat to life because of its associated metabolic complications. The present prospective trial utilized conservative management of childhood acute lymphoblastic leukemia with hyperleukocytosis (total white cell count equal or > 100 x 10(9)/L) by intravenous hydration, urinary alkalinization, and allopurinol presenting without severe life-threatening complications. The median reduction in WBC count was 81.51% (range: 66-98.8%) within a median period of 36 hours (range: 12-60 hours) following hospitalization. There were no failures or treatment related complications. Thus we conclude that in childhood acute lymphoblastic leukemia, hyperleukocytosis can be managed safely and effectively with intravenous hydration, urinary alkalinization, and allopurinol before starting any specific anti-leukemic chemotherapy avoiding risk-associated cranial irradiation, leukapheresis, and exchange transfusion.
