16002 Background: Epoetin alfa (EPO) and darbepoetin alfa (DARB) are used to treat cancer-related anemia and to reduce the requirements for blood transfusions. To date, limited information on the relative effectiveness of these agents in the inpatient setting is available. This analysis evaluated red blood cell (RBC) transfusion rates in cancer patients receiving EPO or DARB during hospitalization. Methods: An analysis of electronic inpatient hospital records from the Premier Perspective Comparative Hospital Database was conducted to compare RBC transfusion rates in cancer patients receiving EPO or DARB therapy. Study subjects were identified through hospitalizations recorded between 07/2002 and 03/2005 from over 500 hospitals nationwide. Patients were required to be ≥18 years old, have a primary admitting diagnosis of cancer and be treated with EPO or DARB during hospitalization. Patients who had received renal dialysis were excluded. To minimize effects of outliers, 5% of patients with extreme doses in each group were excluded from the dosing analysis. In addition to descriptive statistics on transfusion requirements, a multivariate logistic model was employed to isolate the effect of an individual erythropoietic agent on the risk of RBC transfusion after controlling for patient demographics, comorbidities, admission characteristics, use of IV or oral iron and hospitalization severity markers. Results: Among the 24,814 EPO and 2,990 DARB study patients, mean age and gender distribution at admission were similar (age: EPO 65.3 years, DARB 64.5 years; %women: EPO 53%, DARB 55%). Mean cumulative dose per inpatient stay was EPO 61,656 ± 50,274 Units and DARB 259 ± 340 mcg. RBC transfusions occurred in 37.9% of EPO patients compared to 39.8% of DARB patients (p=0.0404). Transfused EPO patients received a mean of 2.24 units versus 2.20 units for DARB patients (p=0.2111). After adjusting for covariates, the multivariate model confirmed that DARB treatment was associated with a higher risk of transfusion compared to EPO (odds ratio: 1.2, 95% CI: 1.1–1.3, p=0.0007). Conclusions: This analysis of inpatients with cancer indicates DARB treatment is associated with a higher risk of receiving RBC transfusion compared to treatment with EPO. [Table: see text]

Myelodysplastic syndromes (MDS) are characterized by chronic refractory cytopenias resulting in increased risk of infection, bleeding, and conversion to acute leukemia. In an effort to improve these cytopenias we have treated 18 patients over a 6- to 8-week period with increasing daily subcutaneous doses of recombinant human granulocyte colony- stimulating factor (G-CSF). Sixteen patients responded with improvement in neutrophil counts. On cessation of treatment these counts returned to baseline values over a 2- to 4-week period. To maintain these improved blood counts 11 patients were treated with G-CSF for more prolonged periods. Ten patients again responded with an increase in total leukocyte counts (1.6- to 6.4-fold) and absolute neutrophil counts (ANC) (3.6- to 16.3-fold), with responses persisting for 3 to 16 months. A significantly decreased risk of developing bacterial infections was noted during periods with ANC greater than 1,500/mm3 as compared with periods of time with ANC less than 1,500/mm3. Two anemic patients had a greater than 20% rise in hematocrit over the study period, and 2 additional patients had a decrease in red blood cell transfusion requirements during G-CSF treatment. Bone marrow myeloid maturation improved in 7 of 9 maintenance phase patients. Three patients progressed to acute myeloid leukemia during treatment. The drug was generally well-tolerated and no severe toxicities were noted. These data demonstrated that G-CSF administered to MDS patients by daily subcutaneous administration was well-tolerated and effective in causing persistent improvement of the neutrophil levels and marrow myeloid maturation. These effects were associated with a decreased risk of infection and, in some patients, with decreased red blood cell transfusion requirements.
