Abstract
Donor-derived hematologic malignancies are rare complications of hematopoietic cell transplantation (HCT). Although these are commonly either a myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML), in general, they are a heterogeneous group of diseases, and a unified mechanism for their development has remained elusive. Here we report next-generation sequencing, including whole-exome sequencing (WES), whole-genome sequencing (WGS), and targeted sequencing, of a case of donor-derived MDS (dMDS) following HCT for high-risk B-lymphoblastic leukemia (B-ALL) in an adolescent. Through interrogation of single-nucleotide polymorphisms (SNPs) in the WGS data, we unequivocally prove that the MDS is donor-derived. Additionally, we sequenced 15 samples from 12 time points, including the initial B-ALL diagnostic sample through several post-HCT remission samples, the dMDS, and representative germline samples from both patient and donor, to show that the MDS-related pathologic mutations, including a canonical ASXL1 (p.Y700*) mutation, were detectable nearly 3 yr prior to the morphological detection of MDS. Furthermore, these MDS mutations were not detectable immediately following, and for >1 yr post-, HCT. These data support the clinical utility of comprehensive sequencing following HCT to detect donor-derived malignancies, while providing insights into the clonal progression of dMDS over a 4-yr period.

Abstract
Donor cell leukemia (DCL) is a rare but severe complication after allogeneic stem cell transplantation. Its true incidence is unknown because of a lack of correct recognition and reporting, although improvements in molecular analysis of donor-host chimerism are contributing to a better diagnosis of this complication. The mechanisms of leukemogenesis are unclear, and multiple factors can contribute to the development of DCL. In recent years, cord blood has emerged as an alternative source of hematopoietic progenitor cells, and at least 12 cases of DCL have been reported after unrelated cord blood transplantation. We report a new case of DCL after unrelated cord blood transplantation in a 44-year-old woman diagnosed as having acute lymphoblastic leukemia with t(1;19) that developed acute myeloid leukemia with normal karyotype and nucleophosmin (NPM1) mutation in donor cells. To our knowledge, this is the first report of NPM1 mutation contributing to DCL development.

Abstract
If leukemia is caused by an "agent" which can pass through the placenta, it could produce leukemic transformation in the maternal cells. Cytogenetic studies were carried out in 5 acute lymphoblastic leukemic children and their parents. Significant abnormalities were found in 3 of the fathers, 4 of the mothers, and all the leukemic children. All but one abnormal metaphase from the mothers of the 2 leukemic boys had a XX sex pattern, indicating that these abnormal metaphases originated in the mother and probably were caused by a chromosomal breaking agent. The abnormal metaphases found in the fathers suggests that they too were exposed to this agent. Therefore, this agent must be present in the immediate environment, and this can pass from the material circulation to the fetus through the placenta and effect the fetus cells. The failure of the infant to eradicate these abnormal cells results in the phenotypical expression of clinical leukemia.

Abstract
A 4-year-old girl with acute myeloblastic leukemia was treated with 50 mg/kg cyclophosphamide daily for 4 days before being given 1.7 X 10(8) bone marrow cells/kg from her HL-A identical, MLC nonreactive, cytogenetically normal brother. The patient died 92 weeks after the marrow graft. Postmortem examination showed increased myeloblasts and promyelocytes. Cytogenetic studies before transplantation showed that all sex determination metaphases had an XX pattern, and 41% of the hyperdiploid metaphases had an additional 19-20(F) chromosome. At autopsy all hyperdiploid metaphases with XY pattern and 43% of the hyperdiploid metaphases with an XX pattern had an additional F chromosome. Occasional metaphases with 47, XX, + F or 47, XY, + F were seen during the follow-up studies. These findings indicated that an acute leukemia had developed in the XY cell line of this artifically induced sex chimeric child. This suggests that a leukemic stimulus other than that proposed to be induced by total-body irradiation existed in this patient and transformed the engrafted cells.
