Zusammenfassung
Die ALL ist die häufigste maligne Erkrankung im Kindes- und Jugendalter. Derzeit werden 80–85 % aller Patienten im ersten Anlauf geheilt. Die Entwicklung der an das Rezidivrisiko angepassten Polychemotherapie inklusive einer konsequenten prophylaktischen Mitbehandlung des Zentralnervensystems sowie die Durchführung der Protokolle in multizentrischen Therapieoptimierungsstudien stellen eine der bedeutendsten Erfolgsgeschichten in der Onkologie dar. Mittels initialer Laborparameter, biologischer Eigenschaften der leukämischen Zellen und des frühen Therapieansprechens lässt sich das Rezidivrisiko sehr gut vorhersehen, sodass die erwähnten Parameter in nahezu allen Studien zur Therapiestratifizierung herangezogen werden. Trotzdem kommt es bei 20 % der Patienten zu einem Rückfall, sodass die Zukunft darauf abzielt, mit Medikamenten, die molekulare leukämiespezifische Veränderungen zum Angriffsziel haben, die therapeutische Effizienz bei Verringerung der Nebenwirkungen zu steigern.
Abstract
Acute lymphoblastic leukemia (ALL) is the most common malignant disease in childhood and adolescence. Nowadays 80–85 % of patients can be cured from the disease with first-line therapy. The development of a relapse risk adapted polychemotherapy, including simultaneous prophylactic treatment of the central nervous system and implementation of the protocols in multicentre therapy optimization trials represent one of the most distinguished stories of success in the whole field of oncology. By using initial laboratory parameters, biological features of the leukemic cells and initial response to therapy, the patient risk for relapse can be predicted very reliably so that in almost all clinical trials most of the prognostic parameters mentioned are used for treatment stratification. Nevertheless, 20 % of patients relapse so that future research aims at developing a more targeted therapy directed towards molecular alterations of the leukemic cells in order to improve therapeutic efficacy and reduce therapy-associated side effects.
