Inevitable and avoidable deaths in childhood ALL.

The causes of 37 deaths among 100 Finnish children with ALL were analyzed after a median follow-up of 5 years. Five children died during primary induction, 9 in complete remission, and 23 in hematological relapse. Infections were responsible for 17 deaths, and four deaths were due to toxicity of chemotherapy. In 16 cases ALL relapse was the major cause of death. Ten of the deaths were defined as "avoidable" because they occurred in potentially curable children, i.e., during induction or primary remission. Critical analysis revealed that 5 out of the 10 "avoidable" deaths might indeed have been prevented by appropriate diagnosis and therapy. We want to emphasize the need for continuous education of all pediatricians involved in the care of ALL patients, as well as the importance of best available clinical expertise and centralization of medical therapy in the efforts to diminish the mortality in childhood ALL.
