Résumé
Prognosis of patients with graft failure is dismal, and re-transplantation is the sole option for long-term survival. To address the interest of haploidentical transplantation as a salvage option in this context, we analyzed data from 24 patients with graft failure or loss re-transplanted with a haploidentical donor who received post-transplant cyclophosphamide (PT-Cy) as graft-versus-host disease prophylaxis (GvHD). Fludarabine-based reduced intensity conditioning was used in 23 patients, and 14 patients received the Baltimore regimen. The median delay between previous and salvage transplantation for graft failure was 63 (39-98) days. Besides PT-Cy, all patients received cyclosporine, and 22 patients also received MMF for GvHD prophylaxis. With a median follow up of 353 (16-2010) days, 1-year OS was 56% (95% CI: 38 - 81). Transplant complications accounted for 80% of deaths. The cumulative incidence of neutrophil engraftment was +30 was 79%. Cumulative incidence of grade II-IV acute GvHD at day-100 was 14%, and 1-year CI of chronic GvHD was 31%. One-year CI of relapse was 13%. Stem cell source did not impact on engraftment, GvHD, relapse nor overall survival. Salvage haploidentical transplant with PT-Cy for rescuing graft failure patients leads to an acceptable 1-year OS and might be a valid option in this poor situation.
