Induction therapy of acute leukemia in children. Current results and problems related to therapeutic aplasia. Apropos of 146 cases

Between 1983 and 1984, 146 children have been treated in the pediatric hematology department of Saint-Louis Hospital (Paris) for induction of acute leukemia (AL). 119 had an acute lymphocytic leukemia (ALL) and 27 an acute non lymphocytic leukemia (ANLL). The rate of complete remission was 94% for all patients (97% in ALL and 81.5% in ANLL). Fever occurred in 95% of children with positive blood cultures in one third on these. Four children died between the fifth and the twenty fifth days after onset of treatment from sepsis. One of these patients was a neonate with ANLL. 127 patients had a central venous line during induction used for blood sampling and treatment (chemotherapy, antibiotics, parenteral nutrition, platelets and red blood cells infusions). This supportive care is very important to improve prognosis of the AL particularly in very intensive chemotherapy.
