title: [Treatment of adult acute lymphoblastic leukemia].
abstract: In patients with adult ALL, substantial progress has been made in the past 20 years. At present a cure rate of 30-40% can be achieved and varies in defined subgroups between 10-51%. ALL does not represent an uniform disease but is formed by biologic subentities, which differ in their natural history, clinical presentation and prognosis. A comprehensive diagnostic examination, including morphology, cytochemistry, immunology, cytogenetic and molecular genetic analysis is a precondition for prognostic assessment and therapeutic stratification. The basic principle of ALL treatment is a combination chemotherapy with sequential administration of induction, consolidation and maintenance therapy. Bone marrow transplantation has become an important part of the treatment strategy and is performed in patients with high risk. In the subgroup of T-ALL a significant progress has been made in the last years with survival rates of 40-50%. In B-ALL the results have been greatly improved to 48-51% by introduction of a specific treatment strategy. However, the results (about 30%) stagnate for the total group of B-lineage-ALL (common ALL, pre-B-ALL, pro-B-ALL). Patients with B-lineage-ALL can be subdivided in a high and low risk group according to the presence of risk factors (age, white blood cell count, time to achieve a complete remission, pro-B-ALL and the translocations t[4;11], t[9;22]). The outcome of the subgroup of adult pro-B-ALL has been substantially improved (50%). An increase of treatment results (20%) appears in outlines for patients above 50 years. The Ph/bcr-abl positive ALL has in spite of improved complete remission rates (60-70%) consistently unfavourable survival rates (10%).
