ABSTRACT
<p><b>OBJECTIVE</b>To analyze the clinical outcome of human leukocyte antigen (HLA) haploidentical peripheral blood stem cell transplantation (PBSCT) from related donors for hematological malignancies.</p><p><b>METHODS</b>Thirty-six patients with hematological malignancies, with a median age of 25 (11-48) years, were transplanted with PBSC from an HLA-haploidentical family donors 7 were 1 locus mismatched and 29 were 2-3 loci mismatched. The recipients received myeloablative conditioning regimen, in combination with different immunosuppressants according to the degree of HLA disparity followed by non-T-cell depleted PBSCT. The median number of CD34+ cells were 11 (4.16-21.00) x 10(6)/kg.</p><p><b>RESULTS</b>All patients achieved sustained, full donor-type engraftment. Fifteen patients (41.7%) developed grade I-II aGVHD. Among 29 patients followed up more than 18 months, 17 (58.6%) developed cGVHD. There was no statistical difference in decrease and recovery of T, B and NK cell subsets after transplantation between HLA haploidentical group and HLA identical PBSCT group. The median follow-up duration was 15 (4 -69) months. Five patients (13.9% ) relapsed. The 2-year probability of leukemia-free survival (LFS) was 82.2%.</p><p><b>CONCLUSION</b>Non-T-cell depleted HLA-haploidentical PBSCT is safe and feasible for patients with hematological malignancies after myeloablative conditioning regimen combined with intensive immunosuppressants.</p>
