[Treatment of bone marrow aplasia in phase I of acute lymphatic leukemia treatment in children].

In the first phase of treatment of acute lymphatic leukemia in children (ALL) with aggresive cytostatic protocols, the doctor is, in some patients, forced to modify the antitumor therapy over a certain period of time because of bone marrow depression. The authors attempted to pull patients with ALL through this critical phase of the disease - by administering "profilactically" Lithium Carbonate (Li2CO3) ( in order to stimulate granulopoiesis) or, if anaemia, leukopenia and thrombocytopenia had already occurred, by administering concentrates of erythrocytes, leukocytes and platelets - without discontinuing the administration of cytostatics. The results of these attempts are reported.
