As predicted, subjects treated daily with corticosterone healed more
slowly than did controls. In contrast, subjects that had been chased daily healed at the same rate as controls. Surprisingly, repeated chasing did not elevate plasma corticosterone despite causing drops in body mass and survival. Additionally, females healed more slowly than males, possibly due to energetic constraints. (C) 2015 Elsevier Inc. All rights reserved.”
“BACKGROUND. Conventional karyorype has an established role in myelodysplastic syndrome (MDS) and is included in the International www.selleckchem.com/products/Gefitinib.html Prognostic Scoring System (IPSS) for patient risk stratification and treatment selection. Although some chromosomal abnormalities have been well
characterized, the significance of several miscellaneous, infrequent, single chromosomal abnormalities remains to be defined. In addition, the emerging therapeutic agents may change the natural Course of disease in patients with MDS and the cytogenetic impact on risk stratification.\n\nMETHODS. Clinicopathologic data were retrieved on 1029 patients who had a diagnosis of primary MDS and had available cytogenetic data (karyotype) on file.\n\nRESULTS. Cytogenetic abnormalities were identified in 458 patients (45%) and occurred most frequently in patients who had refractory anemia with excess blasts (62%). Overall, the 3 cytogenetic risk groups defined by the IPSS-good, intermediate, and poor-effectively stratified CBL0137 the patients’ overall survival (OS) (64 months, 31 months, and 12 months, respectively; P < .001). With the exception of gain of chromosome 8, single cytogenetic abnormalities within
the intermediate group were extremely infrequent in the series but demonstrated variable OS ranging from 10 months for patients who had isochromosome (17q) to 69 months for patients who had deletion of 12p [del(12p)], suggesting different prognostic significance. In the poor cytogenetic risk group, patients with isolated del(7q) 3-MA supplier and derivative (1;7)(q10;p10) had a significantly better median OS than patients who had either loss of chromosome 7 or a complex karyotype (P < .05).\n\nCONCLUSIONS. The Current data generated from a large cohort of patients with primary MDS indicated that some specific cytogenetic abnormalities carry different risk than their IPSS cytogenetic risk-group assignment, especially in the new treatment era. Because of the extreme low frequency, additional combined studies are needed to better categorize some rare single cytogenetic abnormalities within the intermediate cytogenetic risk group.
