Effect of cord blood processing on transplantation outcomes after single myeloablative umbilical cord blood transplantation. - Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation
Variations in cord blood manufacturing and administration are common, and the optimal practice is not known. We compared processing and banking practices at 16 public cord blood banks (CBB) in the United States and assessed transplantation outcomes on 530 single umbilical cord blood (UCB) myeloablative transplantations for hematologic malignancies facilitated by these banks. UCB banking practices were separated into 3 mutually exclusive groups based on whether processing was automated or manual, units were plasma and red blood cell reduced, or buffy coat production method or plasma reduced. Compared with the automated processing system for units, the day 28 neutrophil recovery was significantly lower after transplantation of units that were manually processed and plasma reduced (red cell replete) (odds ratio, .19; P = .001) or plasma and red cell reduced (odds ratio, .54; P = .05). Day 100 survival did not differ by CBB. However, day 100 survival was better with units that were thawed with the dextran-albumin wash method compared with the "no wash" or "dilution only" techniques (odds ratio, 1.82; P = .04). In conclusion, CBB processing has no significant effect on early (day 100) survival despite differences in kinetics of neutrophil recovery.Copyright Â© 2015 American Society for Blood and Marrow Transplantation.

Relationship of race/ethnicity and survival after single umbilical cord blood transplantation for adults and children with leukemia and myelodysplastic syndromes. - Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation
The relationship of race/ethnicity with outcomes of umbilical cord blood transplantation (UCBT) is not well known. We analyzed the association between race/ethnicity and outcomes of unrelated single UCBT for leukemia and myelodysplastic syndromes. Our retrospective cohort study consisted of 885 adults and children (612 whites, 145 blacks, and 128 Hispanics) who received unrelated single UCBT for leukemia and myelodysplastic syndromes between 1995 and 2006 and were reported to the Center for International Blood and Marrow Transplant Research. A 5-6/6 HLA-matched unit with a total nucleated cell count infused of â‰¥2.5 Ã— 10(7)/kg was given to 40% white and 42% Hispanic, but only 21% black patients. Overall survival at 2 years was 44% for whites, 34% for blacks, and 46% for Hispanics (P = .008). In multivariate analysis adjusting for patient, disease, and treatment factors (including HLA match and cell dose), blacks had inferior overall survival (relative risk of death, 1.31; P = .02), whereas overall survival of Hispanics was similar (relative risk, 1.03; P = .81) to that of whites. For all patients, younger age, early-stage disease, use of units with higher cell dose, and performance status â‰¥80 were independent predictors of improved survival. Black patients and white patients infused with well-matched cords had comparable survival; similarly, black and white patients receiving units with adequate cell dose had similar survival. These results suggest that blacks have inferior survival to whites after single UCBT, but outcomes are improved when units with a higher cell dose are used.Copyright Â© 2012 American Society for Blood and Marrow Transplantation.

Pediatric dosing of rituximab revisited: serum concentrations in opsoclonus-myoclonus syndrome. - Journal of pediatric hematology/oncology
To longitudinally assess serum concentrations of rituximab, it was administered intravenously to 25 children with opsoclonus-myoclonus syndrome at 375 mg/m2 on each of 4 consecutive weeks with (Group I and II) or without (Group III) conventional immunotherapy. Serum rituximab levels, drawn before and after each infusion and at later intervals, were analyzed by enzyme-linked immunosorbent assay. Rituximab concentration increased stepwise with each infusion, dropping by the next infusion, thereby forming 4 discrete peaks (Cmax) and troughs (Cmin). It then fell precipitously to trace levels at 4 months. However, Cmax and Cmin curves differed significantly between groups. Compared with the youngest children (Group I), the oldest (Group III) had a 34% lower rituximab concentration at the fourth infusion, 45% less IgM depletion 1 month later, and received 20% less rituximab when the dose was recalculated as mg/kg. Serum IgM and rituximab levels were negatively correlated. Peak rituximab concentration did not correlate with adrenocorticotropic hormone dose. These results indicate that the degree of serum IgM depletion is a useful indicator for rituximab dose equivalency in children of different ages. They also suggest that pediatric rituximab dosing should be based on body weight, not surface area. (ClinicalTrials.gov NCT00244361).
MDM2 polymorphism increases susceptibility to childhood acute myeloid leukemia: a report from the Children's Oncology Group. - Pediatric blood & cancer
The variant polymorphism in the gene MDM2, SNP309, leads to increased level of mdm2 protein and subsequent downregulation of p53 tumor suppressor pathway. Presence of this single nucleotide polymorphism (SNP) has been associated with earlier tumorigenesis in patients with Li-Fraumeni syndrome, as well as decreased survival in patients with CLL. In addition, cells homozygous (G/G) for SNP 309 were found to have 10-fold increase resistance to topoisomerase II inhibitors in vitro.We genotyped children (n = 575) with de novo acute myeloid leukemia (AML) treated on three Children's Oncology Group protocols (CCG 2941/2961/AAML 03P1) for the presence of SNP309. Healthy blood donors were genotyped as control population.The variant G/G genotype was associated with an increased susceptibility to AML (OR 1.5; P = 0.049). However, the presence of the variant allele at SNP309 did not modify disease response or toxicity in children treated on CCG protocols 2941/2961.The variant SNP 309 influences susceptibility to pediatric AML, but does not impact overall response to therapy.(c) 2010 Wiley-Liss, Inc.
Cytidine deaminase genotype and toxicity of cytosine arabinoside therapy in children with acute myeloid leukemia. - British journal of haematology
Cytosine arabinoside (ara-C) is irreversibly deaminated to a non-toxic metabolite by cytidine deaminase (CDA). A common polymorphism, A79C, in the gene encoding cytidine deaminase (CDA) changes a lysine residue to glutamine resulting in decreased enzyme activity. CDA A79C genotypes were determined in 457 children with acute myeloid leukaemia (AML) treated on the Children's Cancer Group (CCG) 2941 and 2961 protocols and analyzed the impact of CDA genotype on therapy outcomes. Postinduction treatment-related mortality (TRM) was significantly elevated in children with the CC genotype (5-year TRM 17 +/- 13% CC vs. 7 +/- 4% AA, 5 +/- 4% AC, P = 0.05). This was more notable in children who received idarubicin, fludarabine, ara-C, and granulocyte colony-stimulating factor (IDA-FLAG; ara-C = 7590 mg/m2) (5-year TRM 24 +/- 21% CC vs. 6 +/- 6% AA, 6 +/- 7% AC, P = 0.07) as consolidation therapy compared to idarubicin, dexamethasone, cytarabine, thioguanine, etoposide and daunomycin (IDA-DCTER; ara-C = 800 mg/m2) (5-year TRM 15 +/- 20% CC vs. 8 +/- 6% AA, 4 +/- 6% AC; P = 0.29). Relapse-free survival was non-significantly increased in children with the CC genotype treated with IDA-FLAG (76 +/- 20% CC vs. 59 +/- 12% AA and 55 +/- 14% AC; P = 0.40). These data indicate that children with a low activity CDA genotype are at increased risk of TRM with ara-C based therapy for AML.
