Although there has been significant progress in the treatment of rare forms of blood cancer in recent years and new drugs have been approved in Germany, the prognosis for many affected individuals remains unfavourable. Research teams at Leipzig University’s Faculty of Medicine are working in several preclinical and translational projects to gain a better understanding of these diseases. The researchers are investigating how bone marrow cancer develops. In addition, they have found a new molecular functional mechanism and have shown that patients with even low amounts of leukaemia cells have a high risk of relapse. The results have been published in journals.
