Early related or unrelated haematopoietic cell transplantation results in higher overall survival and leukaemia-free survival compared with conventional chemotherapy in high-risk acute myeloid leukaemia patients in first complete remission.

Between 1996 and 2004, a total of 708 patients were enrolled in the acute myeloid leukaemia (AML) '96 and '02 studies of the East German Study Group (OSHO). Of these, 138 patients (19.5%) had unfavourable cytogenetics defined as complex karyotype, del (5q)/-5, del (7q)/-7, abn (3q26) and abn (11q23). In all, 77 (56%) achieved complete remission 1 (CR1) after induction chemotherapy and were eligible for haematopoietic cell transplantation (HCT). HCT was performed after a median of two cycles of consolidation chemotherapy (CT) in the AML '96 and one cycle in the AML '02 study (P=0.03). After a median follow-up of 19 months, overall survival (OS) at two years was significantly better in the donor group (52+/-9%) versus the no-donor group (24+/-8%; P=0.005). Differences in outcomes were mainly because of a lower relapse incidence in patients after HCT (39+/-11%) compared with a higher relapse incidence in patients undergoing CT (77+/-10%; P=0.0005). Treatment-related mortality was low and not statistically significantly different between the two treatment groups (15+/-7 and 5+/-5% for HCT and chemotherapy, respectively; P=0.49).We conclude that early HCT from related or unrelated donors led to significantly better OS and leukaemia-free survival compared with chemotherapy in patients with unfavourable karyotype.
