Abstract

Two parallel phase II trials in adults with hematologic malignancies demonstrated comparable survival after reduced-intensity conditioning and transplantation of either 2 HLA-mismatched umbilical cord blood (UCB) units or bone marrow from HLA-haploidentical relatives. Donor choice is often subject to physician practice and institutional preference. Despite clear preliminary evidence of equipoise between HLA-haploidentical related donor and double unrelated donor UCB transplantation, the actual prospect of being randomized between these 2 very different donor sources is daunting to patients and their treating physicians alike. Under these circumstances, it is challenging to conduct a phase III randomized trial in which patients are assigned to the UCB or haploidentical bone marrow arms. Therefore, we aimed to provide an evidence-based review and recommendations for selecting donors for adults without an HLA-matched sibling or an HLA-matched adult unrelated donor.

摘要

两项针对患有血液系统恶性肿瘤的成人患者的平行II期试验表明,在进行强度降低的预处理以及移植2个HLA配型不合的脐带血(UCB)单位或来自HLA单倍型相同亲属的骨髓后,患者的生存率相当。供体的选择通常取决于医生的执业习惯和机构偏好。尽管有明确的初步证据表明HLA单倍型相同的相关供体与双份不相关供体UCB移植之间存在平衡,但在这两种截然不同的供体来源之间进行随机分组的实际前景,对患者及其主治医生来说都是令人生畏的。在这种情况下,开展一项III期随机试验,将患者分配到UCB组或单倍型相同骨髓组,具有挑战性。因此,我们旨在为没有HLA匹配同胞或HLA匹配成人无关供体的成年人选择供体提供基于证据的综述和建议。
