Transplantation/Zelltherapie bei Akuter Myeloischer Leukämie

Die allogene hämatopoetische Stammzelltransplantation ist der bisher effektivste immuntherapeutische Ansatz zur Behandlung der Akuten Myeloischen Leukämie (AML). Bei AML-Patient*innen mit rezidivierter oder chemotherapierefraktärer sowie mit genetischer Hochrisikoerkrankung stellt die allo-HSZT die einzige kurative Option dar. Welche Parameter, Risikofaktoren und aktuellen Entwicklungen in der Therapie eine Rolle spielen, erläutert der Beitrag.

Abstract

To date allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the most effective immunotherapeutic approach for the treatment of acute myeloid leukemia (AML). It involves the transplantation of blood stem cells from a healthy donor into a patient, with the goal of using the donor’s immune system to recognize and attack cancer cells (Graft-versus-leukemia effect). Thereby, allo-HSCT is more efficient than chemotherapy alone, as it combines high dose chemotherapy +/- irradiation with immunotherapy establishing a long-term control of leukemic cells while allowing reconstitution of a healthy donor hematopoiesis and a new immune system. However, the procedure carries significant risks, including the possibility of graft-versus-host disease (GvHD), and requires careful patient selection to ensure the best possible outcome. In AML patients with high-risk, relapsed or chemo-refractory disease allo-HSCT provides the only curative option.

While allo-HSCT is currently the most established form of immunotherapy in the treatment of AML, other approaches that use the immune system to fight cancer are being researched. These may include immunomodulatory drugs or cell therapies such as CAR-T cells, which stimulate the immune system to attack cancer cells. Even if this does not yet play a role in current standard therapy, as our understanding of the immune system and its role in cancer grows, it is likely that targeted immunotherapies will become increasingly important in the treatment of AML The following article gives you an overview of allo-HSCT in AML patients and the current developments.
