Abstract Leukemias accounts for about one third of all cancers in children. Acute leukemias constitute 97% of all childhood leukemias, of which 75% are acute lymphoblastic leukemia (ALL). The different subtypes of ALL (B- or T-cell lineages) depend on the stage of lymphoid differentiation at which a leukemogenic event occur. The improved survival of childhood ALL has focused attention on the late complications of antileukemic therapy. Both short and long-term immunologic effects of chemotherapy have been documented in children treated for. |
