The new edition of this well-received book provides a timely update of current knowledge on the biology, disease classification, and treatment of the acute leukemias – acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). Throughout, the focus is on the provision of state of the art information and guidance that will meet the needs of clinicians. Chapters have been extensively revised to take into account advances in understanding and management that have been achieved over the past few years. In addition, new chapters have been included on selection of AML patients for therapy, a broader discussion of stem cell transplantation in AML, the role of immunotherapy in ALL, the approach to newly diagnosed pediatric ALL, and the diagnosis and management of BCR-ABL-like ALL. New therapies, including investigational ones, are fully covered. As progress continues in the management of acute leukemias this book will be a valuable asset for clinicians at all levels of experience.

Relapse of leukemia following successful remission-induction therapy remains a major obstacle in the treatment of patients with acute leukemia. Leukemia recurs most frequently in patients with acute myeloblastic leukemia (AML) and high risk acute lymphoblastic leukemia (ALL) following chemotherapy and less often in patients with low risk ALL and particularly in patient groups> submitted to allogeneic marrow transplantation.'It is likely that the great majority of these recurrences originate from residual leukemic cells that survive initial remission-induction chemotherapy. Today, several research groups throughout the world place emphasis on studies concerned with the detection and treatment of'minimal residual disease'(MRD). These investigations are conducted with the common objective to tackle the remaining cells.'Minimal Residual Disease in Acute Leukemia: 1986'summarizes the fast advancements in this area. Several disciplines are concerned with the analysis of leukemic cells. The perspectives of cytogenetic and molecular genetic approaches for applica­ tion in the detection of MRD are reviewed. In this respect, modern cyto­ genetics provide highly specific tumor markers. The resolution of cyto­ genetic methods can be particularly improved when combined with other techniques which select relevant subpopulations of cells. Characterization of oncogenes and gene rearrangements, including those of immunoglobulin and T-cell receptor genes, and the measurement of gene products, have been established. Techniques based on these approaches offer interesting tools for the detection of MRD. New possibilities of employing monoclonal anti­ bodies are also presented.
