Four randomized controlled trials, six retrospective and one prospective cohort study were included, covering 1,549 patients. The summary hazard ratios (HRs) for overall survival were 0.84 [95% confidence interval (CI) 0.63-1.12; p = 0.23] for randomized selleckchem studies, 0.70 (95% CI 0.57-0.88; p = 0.002) for cohort studies and 0.75 (95% CI 0.63-0.89; p = 0.001) for all Inhibitors,Modulators,Libraries studies combined. The corresponding HRs for treatment-related mortality (TRM) were 0.81 (95% CI 0.54-1.22; Inhibitors,Modulators,Libraries p = 0.32) for randomized studies, 0.70 (95% CI 0.49-0.99; p = 0.05) for cohort studies and 0.74 (95% CI 0.57-0.95; p = 0.02) for all studies combined. The corresponding HRs for relapse mortality were 1.18 (95% CI 0.69-2.02; p = 0.55) for randomized studies, 1.02 (95% CI 0.65-1.61; p = 0.93) for cohort studies and 1.05 (95% CI 0.

74-1.50; p = 0.79) for all studies combined. In conclusion, the addition of ATG to standard GvHD prophylaxis might improve survival due to improved TRM without decreasing relapse mortality. Inhibitors,Modulators,Libraries Copyright (C) 2012 S. Karger AG, Basel
The clinical heterogeneity of patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) with trisomy 8 as the sole abnormality may result from cytogenetically undetectable genetic changes. The purpose of this study was to identify hidden genomic aberrations not detected by metaphase cytogenetics (MC) using high-resolution single nucleotide polymorphism array (SNP-A)-based karyotyping in AML/MDS patients with a sole trisomy 8. The study group included 8 patients (3 AML and 5 MDS) and array-based karyotyping was done using whole-genome SNP-A (SNP 6.

0 and SNP 2.7M). By SNP-A, additional genomic aberrations not detected by MC were identified in 2 patients: 1 AML patient exhibited Inhibitors,Modulators,Libraries a copy-neutral loss of heterozygosity (CN-LOH) of 3q21.1-q29 and 11q13.1-q25 and the other patient with MDS (refractory cytopenia Inhibitors,Modulators,Libraries with unilineage dysplasia) had CN-LOH of 2p25.3-p15. In particular, the latter patient progressed to AML 18 months after the diagnosis. In 3 patients, aberrations in addition to trisomy 8 were not identified by SNP-A. In the remaining 3 patients, SNP-A could not detect trisomy 8, while trisomy 8 was found in 25-67% of metaphase cells by MC. This study suggests that read the article additional genomic aberrations may in fact be present even in cases of trisomy 8 as sole abnormality by MC, and SNP-A could be a useful karyotyping tool to identify hidden aberrations such as CN-LOH.
