A concordant leukemia is that which occurs in a pair of monozygotic twins; a similar genetic background suggests an monoclonal origin. We present the case of a pair of monozygotic infants with concordant acute myeloid leukemia who underwent a peripheral blood hematopoietic stem-cell transplant (HSCT) from a single, younger human leukocyte antigen-identical sibling donor, using a fractioned graft collected during only one apheresis procedure. Twin A relapsed at +456 and received a second haploidentical HSCT from his father, twin B has been in complete remission since the first HSCT. Both children are in complete remission and with negative minimal residual disease at +900 (after second transplant) and +1488, respectively.
一致性白血病是指发生在一对同卵双胞胎中的白血病;相似的遗传背景提示其起源为单克隆性。我们报告了一对患有一致性急性髓系白血病的同卵婴儿病例,他们接受了来自一名较年轻的、人类白细胞抗原完全相同的同胞供者的外周血造血干细胞移植(HSCT),移植所用的分离移植物仅通过一次单采过程采集。双胞胎A在+456天时复发,并接受了来自其父亲的第二次单倍体相合HSCT,双胞胎B自首次HSCT后一直处于完全缓解状态。两个孩子均处于完全缓解状态,在+900天(第二次移植后)和+1488天时,微小残留病分别为阴性。
