Response to erythropoietic-stimulating agents in patients with chronic myelomonocytic leukemia.

Background: The efficacy of erythropoietic-stimulating agents (ESA) in chronic myelomonocytic leukemia (CMML) is unknown. Our objective was to analyze erythroid response (ER) and overall survival (OS) in a series of 94 patients with CMML treated with ESA.

Methods: We analyzed a series of 94 patients with CMML treated with ESA included in the Spanish and Düsseldorf-MDS registries.

Bloodstream infections in adult patients undergoing cord blood transplantation from unrelated donors after myeloablative conditioning regimen.

The incidence, epidemiology, and risk factors of bloodstream infection (BSI) and their impact on transplant outcomes after umbilical cord blood transplantation (UCBT) are not well defined. Between May 1997 and December 2012, 202 isolates in 189 episodes of BSI were registered in 134 of 241 patients who underwent single-unit myeloablative UCBT. Cumulative incidence (CI) of developing at least 1 episode of BSI was 21%, 29%, 34%, 42%, and 52% at days +7, +14, +30, +100, and +365, respectively.

Multivariate time-dependent comparison of the impact of lenalidomide in lower-risk myelodysplastic syndromes with chromosome 5q deletion.

The impact of lenalidomide treatment on long-term outcomes of patients with lower risk myelodysplastic syndromes (MDS) and chromosome 5q deletion (del(5q)) is unclear. This study used time-dependent multivariate methodology to analyse the influence of lenalidomide therapy on overall survival (OS) and acute myeloblastic leukaemia (AML) progression in 215 patients with International Prognostic Scoring System (IPSS) low or intermediate-1 risk and del(5q). There were significant differences in several relevant characteristics at presentation between patients receiving (n = 86) or not receiving lenalidomide (n = 129).
