Abstract

We performed a survey of the European Cooperative Group for Blood and Marrow Transplantation to analyze the outcome of 625 acute promyelocytic leukemia (APL) patients transplanted with auto- or allogeneic-hematopoietic stem cell transplantation (autoHSCT, alloHSCT) after 1993, in first (CR1) or in second complete remission (CR2). Leukemia-free survival (LFS) at 5 years in CR1 was 69% for 149 patients autografted and 68% for 144 patients allografted, whereas in CR2, LFS was 51% in 195 autoHSCT and 59% in 137 alloHSCT recipients, respectively. In the group of autoHSCT for CR1 (n=149), higher relapse incidence (RI) was associated with shorter time from diagnosis to transplant (<7.6 months); transplant-related mortality (TRM) was increased in older patients (>47 years), whereas for CR2, longer time from diagnosis to transplant (>18 months) was associated with increased LFS and decreased RI. In the alloHSCT group for CR1 (n=144), age (<33 years) was associated with increased LFS and decreased TRM and for CR2 (n=137), the use of mobilized peripheral blood stem cells was associated with decreased TRM. Female recipient, a female donor to male recipient and transplants performed before 1997 were associated with decreased RI. In conclusion, HSCT still appears to have a role in APL, especially for patients in CR2.
