The results might be affected by an underlying selection bias due to the nature of retrospective data. Also, our study was limited by the small number of patients, the heterogeneity of the disease, the transplant procedure and the stem cell source. However, the major strengths of our study were that the follow-up period was sufficient with more than 5 years and the impact of cGVHD as well as pre-transplant

factors on long-term survival Nutlin-3a price were analyzed exclusively for subjects with active leukemia. Conclusion These data show that allo-HCT has the potential to cure active leukemia possibly via cGVHD, particularly in patients with favorable factors even when in non-remission. Further research is warranted to explore the essential factors contributing to the success of allo-HCT such as intensity of conditioning, and GVL effects mediated through cGVHD.
