The myelodysplastic (MDS) are a very heterogeneous group of myeloid disorders characterized by peripheral blood cytopenias and increased risk of transformation to acute myelogenous leukemia (AML). MDS occurs more frequently in older male and in individuals with prior exposure to cytotoxic therapy. ⋯ There are no approved interventions for patients with progressive or refractory disease particularly after hypomethylating based therapy. Options include cytarabine based therapy, transplantation and participation on a clinical trial.

The combination of lenalidomide plus dexamethasone (RD) is very effective for patients with relapsed/ refractory myeloma. However, the effect of RD on bone metabolism has not been previously evaluated in these patients. To address this issue, we initially performed a retrospective study in 106 consecutive patients with relapsed or refractory myeloma who received RD. ⋯ No skeletal-related events were observed in the VRD arm while two, nonresponding patients treated with RD developed a vertebral fracture. We conclude that RD reduces bone resorption only in responding patients with relapsed/refractory myeloma but has no effect on bone formation. Combination with bortezomib, which enhances bone formation, seems to be preferred for the management of myeloma patients with osteolytic disease.

Anemia is now recognized as a risk factor for a number of adverse outcomes in the elderly, including hospitalization, morbidity, and mortality. What constitutes appropriate evaluation and management for an elderly patient with anemia, and when to initiate a referral to a hematologist, are significant issues. Attempts to identify suggested hemoglobin levels for blood transfusion therapy have been confounded for elderly patients with their co-morbidities. Since no specific recommended hemoglobin threshold has stood the test of time, prudent transfusion practices to maintain hemoglobin thresholds of 9-10 g/dL in the elderly are indicated, unless or until evidence emerges to indicate otherwise.

Conditioning regimen including fludarabine, intravenous busulfan (Bx), and 5 mg/kg total dose of rabbit antithymocyte globulin (r-ATG) (FBx-ATG) results in low incidence of graft-versus-host disease (GVHD) and non-relapse mortality (NRM) after allogeneic hematopoietic stem cell transplantation (Allo-HSCT) from HLA-matched related or unrelated donors (MUD). However, whether this platform produces similar results in the setting of one mismatch unrelated donor (MMUD) Allo-HSCT is not known. We retrospectively analyzed patients aged less than 65 years who were diagnosed with hematological malignancies and received FBx-ATG regimen prior to Allo-HSCT from MUD (N = 74) or MMUD (N = 40). ⋯ MMUD: 61%, P = 0.762) were not different between both groups. With a median follow up of 24 months, 35 of 74 MUD patients (47%) and 19 of 40 MMUD patients (48%) were free of both disease progression and immunosuppressive treatment. We conclude that the FBx-ATG regimen results in low incidences of NRM and GVHD in both MUD and the MMUD recipients.
