A Randomized Multicenter Study to Compare Two Types of Transplant in Adult Patients With Hematologic Malignancies

Study Overview
=================
Brief Summary
-----------------
This is an open-label, prospective, observational, multicenter, randomized study to compare the efficacy between unrelated umbilical cord blood transplantation (UCBT) and HLA-haploidentical related hematopoietic stem cell transplantation ,after myeloablative conditioning for adult patients with hematologic malignancies.
