Predictors of Response in Patients Receiving CD34-Selected Stem Cell Infusions without Conditioning to Correct Graft Failure Following Allogeneic Stem Cell Transplantation

Conclusions: This analysis represents the largest report of outcomes in patients who have received a CD34+ selected stem cell infusion without conditioning for GF. Negative donor/recipient CMV serostatus and sex matching predicted response. In responding patients, GF initially affecting <3 lineages was a predictor of better OS at 5 years. New strategies including cytokine or agonist support, or second transplant need to be investigated in partially or non-responding patients.DisclosuresHough: University College London Hospital's NHS Foundation Trust: Employment.
