Blood and marrow transplantation in elderly acute myeloid leukaemia patients - older certainly is not better

Abstract

Acute myeloid leukaemia in the elderly is a disease with distinct biological properties, commonly associated with leukaemic cell treatment resistance and with an increased number of high-risk features, including concomitant myelodysplasia and poor-risk cytogenetic abnormalities such as monosomy 5 and 7. Complete remission rates after standard induction chemotherapy in patients above age 60 years are less than 50%, with long-term survival rates below 10%. Post-remission stem cell transplant therapies have not been studied extensively. Autologous transplants can result in an acceptable 3-year leukaemia-free survival rate of up to 47%, yet this procedure is applicable only to a small minority of patients. Myeloablative allogeneic transplants similarly show feasibility in selected few patients and in general are very toxic. Non-myeloablative allogeneic transplants are associated with reduced toxicity, but are plagued by an increased relapse rate. The latter strategy appears promising, but must be validated in larger, multi-centre prospective trials, in which outcomes are compared to non-transplant approaches.
