ABSTRACT
OBJECTIVE:
To analyse the engraftment, transplant-related complications and survival after unrelated cord blood transplantation (UCBT) in patients with hematologic malignancies.METHODS:
Twenty eight consecutive adult patients with hematological malignancies were treated with UCBT and 20 of them were advanced-stage diseases. Double or multiple UCB grafts were used for 18 patients, while single UCB graft for 10 patients. Myeloablative conditioning regimens were given to 26 cases and nonmyeloablative regimens to 2 cases. All patients were given a combination of cyclosporine (CsA) and mycophenolate mofetil (MMF) for graft-versus-host disease (GVHD) prophylaxis.RESULTS:
Median time to neutrophil engraftment (≥ 0.5 × 10(9)/L) in 26 patients was 18 (14 - 37) days and platelet engraftment (≥ 20 × 10(9)/L) in 22 patients was 30 (25 - 49) days. Chimerism was weekly assessed by PCR analysis of short tandem repeat (STR) sequences in whole blood or bone marrow and 22 cases were confirmed of fully donor chimeric from 7 to 21 days after transplantation. Eighteen cases developed acute GVHD, greater than grade II in 1, and 6 of 22 patients who survived more than 100 days developed limited chronic GVHD. Eighteen cases were alive in hematologic remission at a median follow-up of 9.5 (2.5 - 72.0) months. The probability of event-free survival at 3 years was 56.7%. Two cases relapsed and 8 of 10 cases died of transplant related complications.CONCLUSIONS:
UCBT could be safely and effectively used for adult patients with hematologic malignancies. Use of double UCB units is a strategy extending the feasibility of UCBT.
