Donor Lymphocyte Infusions for Chronic Myeloid Leukemia Relapsing after Allogeneic Stem Cell Transplantation: May We Predict Graft-versus-Leukemia Without Graft-versus-Host Disease?

AbstractDonor lymphocyte infusions (DLI) are an effective treatment for relapsed chronic myeloid leukemia (CML) after allogeneic stem cell transplantation (alloSCT). Leukemia resistance and secondary graft-versus-host disease (GVHD) are major obstacles to success with DLI. The aim of this study was to identify pre-DLI factors associated with prolonged survival in remission without secondary GVHD. We retrospectively analyzed 500 patients treated with DLI for CML relapse (16% molecular, 30% cytogenetic, and 54% hematological) after alloSCT. The overall probabilities of failure- and secondary GVHD–free survival (FGFS) were 29% and 27% at 5 and 10 years after DLI, respectively. The type of relapse was the major factor influencing FGFS (40% for molecular and/or cytogenetic relapse and 20% for hematological relapse at 5 years, P 50% at 5 years) when DLI were given beyond 1 year from alloSCT for molecular and/or cytogenetic CML relapse that was not preceded by chronic GVHD

Cellular adoptive immunotherapy after allogeneic stem cell transplantation.

Contains fulltext : 48013schattenberg.pdf (publisher's version ) (Closed access)PURPOSE OF REVIEW: This review presents the role of donor lymphocyte infusion, natural killer cells, and dendritic cells in cellular immunotherapy after allogeneic stem cell transplantation. RECENT FINDINGS: It becomes increasingly possible to infuse more specialized subsets of lymphocyte cells after transplantation. The infusion of natural killer cells, especially in non human leukocyte antigen-identical transplantation, may become an important tool in enhancing the graft-versus-tumor effect. Vaccination of patients after stem cell transplantation with autologous-derived dendritic cells merits further investigation. SUMMARY: Stem cell transplantation has evolved to a specialized form of immunotherapy

Differences between the different conditioning regimens for allogeneic stem cell transplantation.

Contains fulltext : 50681.pdf (publisher's version ) (Closed access)PURPOSE OF REVIEW: The aim of this article is to compare the differences in efficacy and toxicity between the various conditioning regimens for allogeneic stem cell transplantation. RECENT FINDINGS: Several studies, all retrospective, that compare the impact of various different conditioning regimens amongst each other are presented. Reduced intensity conditioning apparently lowered transplant-related mortality in patients with minimal residual disease who were at high risk for treatment-related mortality. In contrast, patients with active disease could only be salvaged when a myeloablative conditioning regimen was used. By consequence, it was concluded that patients without contraindications for a myeloablative conditioning regimen should not receive reduced regimens outside a prospective randomized trial. SUMMARY: Despite high expectations, non-myeloablative conditioning regimens and regimens that have been reduced in intensity did not prove to be superior in survival when the outcomes were compared with those obtained with conventional myeloablative conditioning. Randomized prospective studies are needed to explore the appropriate niche for the various different regimens
