title: Allogeneic haematopoietic cell transplantation for chronic myelogenous leukaemia in the era of imatinib: a retrospective multicentre study.
abstract: OBJECTIVE
  To analyse the results of allogeneic haematopoietic cell transplantation (HCT) in patients with advanced stages of Philadelphia chromosome-positive chronic myelogenous leukaemia (CML) who had previously been treated with imatinib mesylate (IM).
  
  
  METHODS
  We analysed the outcome of 61 patients with CML who had received allogeneic HCT from sibling (n = 18) or unrelated (n = 43) donors after having been treated with IM. Forty-one patients had received IM because of accelerated or blast phase CML. Conditioning therapy contained standard doses of busulfan (n = 25) or total-body irradiation (n = 20) in conjunction with cyclophosphamide in the majority of cases. Sixteen patients received dose-reduced conditioning with fludarabine-based regimens.
  
  
  RESULTS
  The incidence of grades II-IV and III-IV graft-versus-host disease was 66% and 38% respectively. The probability of overall survival (OS), disease-free survival (DFS) and relapse at 18 months for the whole patient cohort were 37%, 33% and 24% respectively. The probability of non-relapse mortality (NRM) at 100 d and 12 months was 30% and 46% respectively. Univariate analysis showed that fludarabine-based conditioning therapy, age > or = 40 yr and >12 months interval between diagnosis and transplantation were associated with a significantly lower OS and DFS and a higher NRM.
  
  
  CONCLUSIONS
  These data suggest that although pretreatment with IM is not an independent negative prognostic factor, it cannot improve the dismal prognosis of CML patients at high risk for transplant-related mortality.
