For example, much of the progress in improving survival rates for children with acute lymphoblastic leukemia (ALL) can be attributed to the conduct of sequential phase III clinical trials in which more effective treatment approaches for children with ALL were reliably identified and carried forward as the standard of care that replaced less effective therapies. The end result of these series of clinical trials conducted over more than four decades has been the identification of treatments that produce much higher 5-year survival rates than those previously achieved (Fig. 446-1).
