Treating the "older" adult with acute lymphoblastic leukemia.
Acute lymphoblastic leukemia (ALL) in adults is a rare disease. The results of therapy remain unsatisfactory, and progress has been relatively slow. This article will focus on curative therapy in patients aged 30 to 60 years, but will also discuss the management of elderly patients with ALL. Recent large trials have increased our knowledge of the factors that determine outcome, and have clarified the role of blood and marrow transplantation in the management of this disease. These trials have also highlighted the major issues we need to focus on if we are to improve outcomes. This article describes the results of chemotherapy and blood and marrow transplantation for Philadelphia chromosome negative and positive adult ALL in the "older" adult patient, but also critically examines the major controversies and suggests how they might be resolved. The role of allografting in adult ALL is comprehensively discussed. Results of recent studies on T-cell ALL and reduced-intensity allografting are reviewed. A better understanding of the biology of the disease (including gene profiling) may allow individualization of therapy and, in time, targeted therapy.
