Predictors of Outcome for Allogeneic Stem Cell Transplantation with a Reduced Intensity Pentostatin/TBI Conditioning Regimen in T-Cell Lymphomas: A Single Center Experience

Background: Allogeneic hematopoietic stem cell transplantation (alloSCT) is a potential curative option for patients with relapsed/refractory T-cell lymphoma (TCL).A reduced intensity conditioning (RIC) regimen of infusional pentostatin and 6 Gy of total body irradiation (TBI) has been shown to be well-tolerated and to have favorable engraftment kinetics 1. We utilized this regimen for patients with aggressive TCL undergoing alloSCT due to the demonstrated activity of pentostatin as a single agent in TCL and its potential impact, along with TBI, on eradicating residual TCL.
