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]

Background: We aimed to describe red blood cell (RBC) transfusions in the emergency department (ED) with a particular focus on the hemoglobin (Hb) level thresholds that are used in this setting. Methods: This was a cross-sectional study of 12 EDs including all adult patients that received RBC transfusion in January and February 2018. Descriptive statistics were reported. Logistic regression was performed to assess variables that were independently associated with a pre-transfusion Hb level ≥ 8 g/dL. Results: During the study period, 529 patients received RBC transfusion. The median age was 74 (59–85) years. The patients had a history of cancer or hematological disease in 185 (35.2%) cases. Acute bleeding was observed in the ED for 242 (44.7%) patients, among which 145 (59.9%) were gastrointestinal. Anemia was chronic in 191 (40.2%) cases, mostly due to vitamin or iron deficiency or to malignancy with transfusion support. Pre-transfusion Hb level was 6.9 (6.0–7.8) g/dL. The transfusion motive was not notified in the medical chart in 206 (38.9%) cases. In the multivariable logistic regression, variables that were associated with a higher pre-transfusion Hb level (≥8 g/dL) were a history of coronary artery disease (OR: 2.09; 95% CI: 1.29–3.41), the presence of acute bleeding (OR: 2.44; 95% CI: 1.53–3.94), and older age (OR: 1.02/year; 95% CI: 1.01–1.04). Conclusion: RBC transfusion in the ED was an everyday concern and involved patients with heterogeneous medical situations and severity. Pre-transfusion Hb level was rather restrictive. Almost half of transfusions were provided because of acute bleeding which was associated with a higher Hb threshold.

Background and Objectives. High-intensity ICU staffing model is associated with quality and outcome improvements. Restrictive red blood cell (RBC) transfusion strategies have been shown to have equivalent mortality to a more liberal strategy in the ICU. We examined the effect of high-intensity staffing on pretransfusion hemoglobin levels, RBC transfusion rates and length of ICU stay. Materials and Methods. The study was a retrospective chart review (n = 196) of all patients admitted to the adult medical/surgical ICU for more than 24 hours one year prior to and after institution of the high-intensity staffing model. Results. Matched for demographics and diagnosis, RBC transfusion rates pre- versus postinstitution of the high-intensity staffing model was 42% versus 27%, respectively, and pretransfusion hemoglobin levels were lower (8.94 to 7.39 g/dL). Length of stay was 4.1 days pre–high-intensity staffing and 4.0 days post–high-intensity staffing. Conclusions. High-intensity ICU staffing resulted in fewer RBC transfusions and lower transfusion thresholds. This restrictive RBC transfusion strategy had no adverse effects on patient ICU length of stay.

Background. Hematologic improvement (HI) occurs in some patients with acquired anemias and transfusional iron overload receiving iron chelation therapy (ICT) but there is little information on transfusion status after stopping chelation.Case Report. A patient with low IPSS risk RARS-T evolved to myelofibrosis developed a regular red blood cell (RBC) transfusion requirement. There was no response to a six-month course of study medication or to erythropoietin for three months. At 27 months of transfusion dependence, she started deferasirox and within 6 weeks became RBC transfusion independent, with the hemoglobin normalizing by 10 weeks of chelation. After 12 months of chelation, deferasirox was stopped; she remains RBC transfusion independent with a normal hemoglobin 17 months later. We report the patient’s course in detail and review the literature on HI with chelation.Discussion. There are reports of transfusion independence with ICT, but that transfusion independence may be sustained long term after stopping chelation deserves emphasis. This observation suggests that reduction of iron overload may have a lasting favorable effect on bone marrow failure in at least some patients with acquired anemias.

Abstract Abstract 3008 Poster Board II-984 Introduction: The erythropoiesis-stimulating agents (ESAs) epoetin alfa (EA) and darbepoetin alfa (DA) increase hemoglobin (Hb) levels and reduce red blood cell (RBC) transfusion requirements in patients (pts) with cancer chemotherapy-associated anemia (CAA). Extended-interval ESA dosing (i.e., administration less than once weekly) is a common practice with DA, which is FDA approved for dosing once every 3 weeks (q3wks); a previous study of the North Central Cancer Treatment Group suggested that EA can also be given less often than the FDA-approved once weekly schedule (Steensma DP et al, J Clin Onc 2006; 24:1079). The present study compared 2 different q3wks extended-interval EA regimens with weekly fixed-dose EA and with q3wks DA in pts with CAA. Patients and Methods: Eligible pts were receiving chemotherapy for a non-myeloid malignancy and had Hb <10.5 g/dL, ferritin >20 ng/mL, weight >40 kg and <150 kg, and ECOG performance score £2. Pts were randomized 1:1:1:1 to receive EA 40,000 Units subcutaneously (SC) once weekly (40K arm), EA 80,000 Units SC q3wks (80K arm), EA 120,000 Units SC q3wks (120K arm), or DA 500 mcg SC q3wks (DA arm), for 15 weeks. EA and DA were held for Hb >12 g/dL and restarted at a lower dose when Hb fell to '11.5 g/dL. All pts received ferrous sulfate 325 mg orally once daily, if tolerated. Quality of life (QOL) was measured using the Symptom Distress Scale (SDS), Brief Fatigue Inventory (BFI), FACT-An, and Linear Analogue Self Assessment (LASA) tools. The primary endpoint was the proportion of pts achieving Hb≥11.5 g/dL or increment of Hb>2.0 g/dL from baseline. Secondary endpoints included RBC transfusion requirements, adverse events (AEs), and QOL. Results: 239 pts (236 evaluable) enrolled at 10 MCCRC sites between Feb. 2007 and Dec. 2008; 62% of pts completed all study interventions. The median age of enrolled pts was 66 years; 42.4% were men, 91.5% had solid tumors, 26.7% had severe anemia (Hb <9.5 g/dL), and 44.9% were receiving platinum-containing regimens. Baseline characteristics were balanced between study arms, with the exception of gender (39% female for 40K, 60% for 80K, 43% for 120K, 26% for DA). There were no significant differences between treatment arms in the proportion of pts achieving a Hb response (68.9% for 40K, 61.7% for 80K, 65.5% for 120K, and 66.7% for DA; p>0.41 for all comparisons), but the median Hb increment from baseline was higher in the 40K and DA arms compared to the 2 extended dosing EA arms (40K-2.8 g/dL, 80K-2.0 g/dL, 120K-2.1 g/dL, DA-2.6 g/dL; p=0.005 for 40K vs 80K). Hb response was achieved more quickly in the weekly EA arm, but the difference was not significant (40K-32 days, 80K-50 days, 120K-49 days, DA-49 days; p>0.13). The proportion of patients transfused was similar between arms (40K-27.9%, 80K-33.3%, 120K-22.4%, DA-29.8%; p>0.49). There were no significant differences in QOL changes. Deaths were also similar between arms (40K-5 pts, 80K-7 pts, 120K-7 pts, DA-1 pt, p>0.10) and were primarily due to disease progression. AEs and serious AEs were comparable between study groups; grade 3/4 AEs were observed in 22% of pts in the 40K arm, 22% on 80K, 17% on 120K, and 13% on DA; p>0.56. The median total dose of EA used was highest in the 120K arm (40K-265,000 U; 80K-240,000 U; 120K-360,000 U; p=0.0009 for 40K vs 120K), while pts on the 40K arm were more likely to omit a dose due to a high Hb (40K-63.9% of pts omitted at least one dose; 80K-30.0%; 120K-34.5%; DA-43.6%, p<0.0001 for 40K vs 80K). Conclusion: Although there was no significant difference in the proportion of responding pts (the primary endpoint), Hb increments from baseline were moderately higher with the 2 FDA-approved regimens – weekly EA 40,000 Units, and q3wk DA 500 mcg – than with the extended dosing regimens. This study was supported by a grant from Centocor Ortho Biotech, Inc. to the MCCRC. Disclosures: No relevant conflicts of interest to declare.

e14685 Background: Anemia is a common and unfortunate consequence of chemotherapy; patients receiving a variety of chemotherapy regimens often develop chemotherapy–induced anemia (CIA), which contributes to poor outcomes including increased mortality. Prompt and effective treatment of CIA is essential to prevent fewer chemotherapy dose delays and reductions. Optimal therapy of CIA is controversial and involves the solitary and combined use of intravenous iron, red blood cell (RBC) transfusions, and erythropoietin stimulating agents (ESAs). Despite the baseline coagulopathies present in patients with malignancy, administration of both RBC transfusions and ESAs is associated with venous thromboembolism (VTE). It remains unknown whether the risk of VTE in patients with CIA is greater among patients who receive RBC transfusions or ESAs. Methods: A retrospective single-institution study analyzed 7360 patients with varying malignancies who developed CIA and received ESAs and RBC transfusion from 1998-2017. These patients were evaluated for subsequent development of VTE and categorized by prior receipt of RBC transfusion or ESA. Results: Among the 7360 patients with CIA, 5503 received either RBC transfusion or ESA and 1857 received both. Among all patients, 3466/7360 (47.1%) developed a VTE. The absolute risk of developing a VTE with receipt of a RBC transfusion was 0.38 compared to 0.19 with ESA. Patients with CIA who received RBC had twice the risk of developing a VTE compared with those who received ESA (p < 0.0001). Conclusions: While both RBC transfusion and ESA administration are independently associated with VTE, our data suggests a greater risk of VTE development with RBC transfusion as compared with ESA administration.[Table: see text]

AbstractThe influence of perioperative red blood cell (RBC) transfusion on prognosis of glioblastoma patients continues to be inconclusive. The aim of the present study was to evaluate the association between perioperative blood transfusion (PBT) and overall survival (OS) in patients with newly diagnosed glioblastoma. Between 2013 and 2018, 240 patients with newly diagnosed glioblastoma underwent surgical resection of intracerebral mass lesion at the authors’ institution. PBT was defined as the transfusion of RBC within 5 days from the day of surgery. The impact of PBT on overall survival was assessed using Kaplan–Meier analysis and multivariate regression analysis. Seventeen out of 240 patients (7%) with newly diagnosed glioblastoma received PBT. The overall median number of blood units transfused was 2 (95% CI 1–6). Patients who received PBT achieved a poorer median OS compared to patients without PBT (7 versus 18 months; p < 0.0001). Multivariate analysis identified “age > 65 years” (p < 0.0001, OR 6.4, 95% CI 3.3–12.3), “STR” (p = 0.001, OR 3.2, 95% CI 1.6–6.1), “unmethylated MGMT status” (p < 0.001, OR 3.3, 95% CI 1.7–6.4), and “perioperative RBC transfusion” (p = 0.01, OR 6.0, 95% CI 1.5–23.4) as significantly and independently associated with 1-year mortality. Perioperative RBC transfusion compromises survival in patients with glioblastoma indicating the need to minimize the use of transfusions at the time of surgery. Obeying evidence-based transfusion guidelines provides an opportunity to reduce transfusion rates in this population with a potentially positive effect on survival.
