Abstract

We analyzed 113 patients with lymphoma who underwent allogeneic transplantation with reduced-intensity conditioning (allo-RIC) regimens at a single institution, from February 2001 through November 2009, searching for factors predictive of the outcome. At the time of transplantation, 60% of patients were in CR, 29% in PR and 11% had progressive or stable disease. At a median follow-up of 34 months (confidence interval (CI) 17-45), the 3-year OS and PFS were 59% (CI 48-68%) and 51% (CI 41-61%), respectively. The 100-day and 2-year nonrelapse mortalities (NRM) were 6% and 28% (CI 20-35%), respectively. Grade II-IV acute GVHD (aGVHD) incidence was 38%, and the global incidence of chronic GVHD was 33%. In univariate analysis, OS was influenced by disease status before allo-RIC; aGVHD negatively affected on survival. Similarly, PFS was influenced only by disease status. Histological subtype did not affect OS or PFS. We conclude that disease status at the time of transplantation significantly influences survival in patients receiving allo-RIC for lymphoma, whereas histological subtype does not. This reinforces the need to administer more effective debulking treatments to lymphoma patients, for optimal benefit of allogeneic immune recognition of minimal residual disease, independently from lymphoma histology.
