Contemporary treatments for acute lymphoblastic leukemia (ALL) can cure more than 80% of children with this disease but fewer than 50% of adults. 1 Current risk-directed therapy is intended to improve not only the cure rates in ALL, but also the quality of life of the patients, in terms of decreased acute morbidity and long-term sequelae. 2 As we continue to learn more about the mechanisms of leukemic cell transformation and the development of drug resistance, as well as the germline genetic influences on a patient’s responses to chemotherapy, the closer we are to an era of personalized therapy for ALL, in which common protocols for large groups of patients will be replaced by treatments based on the unique molecular targets and pharmacodynamics of individual patients. 3 In this issue of Seminars in Hematology, a group of distinguished investigators review the current and emerging concepts of leukemia pathobiology and therapy, emphasizing issues that must be addressed if we expect to eradicate ALL without undue side effects that may preclude a normal productive life.Leukemia is caused by sequential alterations in proto-oncogenes, tumor-suppressor genes, and microRNA genes of hematopoietic stem cells or their committed progenitors. 3, 4 These fundamental changes alter key regulatory processes in target cells by unleashing an unlimited capacity for self-renewal, subverting the controls of normal proliferation, blocking cell differentiation, and promoting resistance to death signals (apoptosis). 3, 4 Despite remarkable progress in cataloging the molecular lesions that are common to ALL, our understanding of how such changes cooperate to produce overt ALL is still rudimentary at best. Mullighan and Downing address this problem by adroitly discussing recent advances in the use of highresolution genome-wide platforms to detect DNA copy number abnormalities and regions of loss-of-heterozygosity. Together with transcriptional profiling, these studies can be used to determine interactions among tumor-suppressor genes and other oncogenic lesions that not only provide valuable mechanistic insights, but may also qualify as useful targets for therapy. 5, 6 The authors have taken considerable care to highlight some of the technical aspects of data
