Four-agent induction/consolidation therapy for childhood acute lymphoblastic leukemia: an Indian experience.
During 1984-1986, a total of 128 children with acute lymphoblastic leukemia (ALL) were treated with an induction-consolidation regimen consisting of doxorubicin, vincristine, cytosine-arabinoside, and prednisolone. One hundred two (80%) patients belonged to high-risk group. The complete remission rate for all the patients was 91%. The event-free survival at 5 years was 32.0% +/- 23%. On multivariate analysis the event-free survival and disease-free survival was not altered by age, sex, WBC count, platelet count, LDH level, and surface phenotype. Infection due to prolonged marrow aplasia was a common complication, leading to mortality of 8 patients during induction and 33 patients during first remission. The relapse rate has been 36% (42 patients). The predominance of high-risk ALL in the Indian population underscores the need for intensive therapy. Improved supportive care during induction and remission seems essential to decrease therapy-related mortality, leading to improved survival.
