Abstract
BACKGROUND Anaemia is a common side effect of cancer treatments and can lead to a reduction in quality of life. Erythropoiesis-stimulating agents (ESAs) are licensed for use in conjunction with red blood cell transfusions to improve cancer treatment-induced anaemia (CIA). OBJECTIVE To investigate the effectiveness and cost-effectiveness of ESAs in anaemia associated with cancer treatment (specifically chemotherapy). DATA SOURCES The following databases were searched from 2004 to 2013: The Cochrane Library, MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, EMBASE, Web of Science, Cumulative Index to Nursing and Allied Health Literature, British Nursing Index, Health Management Information Consortium, Current Controlled Trials and ClinicalTrials.gov. The US Food and Drug Administration and European Medicines Agency websites were also searched. Bibliographies of included papers were scrutinised for further potentially includable studies. REVIEW METHODS The clinical effectiveness review followed principles published by the NHS Centre for Reviews and Dissemination. Randomised controlled trials (RCTs), or systematic reviews of RCTs, of ESAs (epoetin or darbepoetin) for treating people with CIA were eligible for inclusion in the review. Comparators were best supportive care, placebo or other ESAs. Anaemia- and malignancy-related outcomes, health-related quality of life (HRQoL) and adverse events (AEs) were evaluated. When appropriate, data were pooled using meta-analysis. An empirical health economic model was developed comparing ESA treatment with no ESA treatment. The model comprised two components: one evaluating short-term costs and quality-adjusted life-years (QALYs) (while patients are anaemic) and one evaluating long-term QALYs. Costs and benefits were discounted at 3.5% per annum. Probabilistic and univariate deterministic sensitivity analyses were performed. RESULTS Of 1457 titles and abstracts screened, 23 studies assessing ESAs within their licensed indication (based on start dose administered) were included in the review. None of the RCTs were completely aligned with current European Union licenses. The results suggest a clinical benefit from ESAs for anaemia-related outcomes and an improvement in HRQoL scores. The impact of ESAs on AEs and survival remains highly uncertain, although point estimates are lower, confidence intervals are wide and not statistically significant. Base-case incremental cost-effectiveness ratios (ICERs) for ESA treatment compared with no ESA treatment ranged from £ 19,429 to £ 35,018 per QALY gained, but sensitivity and scenario analyses demonstrate considerable uncertainty in these ICERs, including the possibility of overall health disbenefit. All ICERs were sensitive to survival and cost. LIMITATIONS The relative effectiveness of ESAs was not addressed; all ESAs were assumed to have equivalent efficacy. No studies were completely aligned with their European labelling beyond the starting dose evaluated. There is questionable generalisability given that the included trials were published >20 years ago and there have been many changes to chemotherapy as well as to the quality of supportive treatment. Trial quality was moderate or poor and there was considerable unexplained heterogeneity for a number of outcomes, particularly survival, and evidence of publication bias. Adjustments were not made to account for multiple testing. CONCLUSIONS ESAs could be cost-effective when used closer to licence, but there is considerable uncertainty, mainly because of unknown impacts on overall survival.

Pirker R, Hedenus M, Vansteenkiste J, Hernandez E, Belton L, Terwey JH. Effectiveness of Darbepoetin Alfa for Chemotherapy-induced Anemia When Initiated at Hemoglobin ≤10 g/dL. Clin Ther 2015; 38:122-135.e6. [PMID: 26730453 DOI: 10.1016/j.clinthera.2015.11.012] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2015] [Revised: 11/16/2015] [Accepted: 11/17/2015] [Indexed: 11/26/2022]
Abstract
PURPOSE Limited data are available to describe the effectiveness of darbepoetin alfa (DA) in terms of hemoglobin (Hb) and transfusion outcomes when initiated at Hb ≤10 g/dL (the threshold specified in the summary of prescribing characteristics). We assessed DA, initiated according to current labeling (Hb ≤10 g/dL), in chemotherapy-induced anemia (CIA). METHODS Data for patients with cancer and CIA who initiated DA at Hb ≤10 g/dL were extracted from a database of Amgen-sponsored trials. A comparative analysis was limited to randomized, controlled trials in patients treated with DA or control (placebo/best supportive care). Data for the DA arm(s) of randomized, multiple-arm, or prospective, single-arm trials were also extracted (DA-only analysis; non-front-loaded studies only). Outcomes included Hb increase ≥1 g/dL or ≥2 g/dL during the first 12 weeks of treatment. Crude and Kaplan-Meier proportions of patients who experienced each outcome and time (days) to each outcome were summarized by treatment arm. Meta-analysis (fixed-effects inverse-variance method) was performed to compare outcomes for DA with control. FINDINGS The comparative analysis included 4 studies (2 in lung cancer, 1 in lymphoproliferative disease, and 1 in non-myeloid malignancy: DA, n = 261; control, n = 273). The DA-only analysis included 15 studies (n = 3768). In comparative analyses, more patients who received DA than placebo achieved Hb increase of ≥1 g/dL (fixed-effects hazard ratio [HR] = 2.07; 95% CI, 1.62-2.63) or ≥2 g/dL (HR = 2.91; 95% CI, 2.09-4.06). Median times to ≥1 g/dL or ≥2 g/dL increase were 43 or 78 days for DA (not evaluable for placebo). Transfusions were less common in patients who received DA (HR = 0.58; 95% CI, 0.44-0.77). Addition of 2 dose-finding studies did not change the findings of the main comparative analysis. Results were similar in the DA-only analyses. IMPLICATIONS This is the first patient-level meta-analysis, to our knowledge, to evaluate the efficacy in terms of Hb response of DA treatment when initiated according to current product labeling in patients with CIA. Limitations include the small number of studies and patients eligible for inclusion in the comparative analyses and the absence of non-Amgen trials of DA. The results of the comparative analysis confirm that DA is more effective than placebo at increasing serum Hb levels and at reducing the need for transfusion in patients with CIA when treatment is initiated at Hb ≤10 g/dL, as per current product labeling.

Abstract
Background: Anemia is a common complication among patients with cancer receiving chemotherapy and can cause significant costs to health plans. Objective: The objective of this study is to estimate the annual budget impact of drug treatment associated with treating cancer patients with anemia due to the effect of concomitant myelosuppressive chemotherapy (i.e., chemotherapy-induced anemia [CIA]) with erythropoiesis stimulating agents (ESAs), either darbepoetin alfa (DA) once every 3 weeks (Q3W) or epoetin alfa (EA) once every week (QW), for a large US health plan in 2014. Methods: Using a patient database from a large US health plan in 2010 (n = 14 811 119), the potential CIA patient population was determined (1842 patients each per DA and EA). A budget impact of ESA treatment on this patient population in 2014 was calculated. The analysis assumed a minimum of 2 additional months of chemotherapy from initiation of the analysis. The 2014 Centers for Medicare and Medicaid Services (CMS) reimbursement rates used were: average sales price +12% of $3.68/mcg (DA) and $11.38/1000 IU (EA), and office-based injection cost of $25.08. Results: The estimated 2014 annual average drug costs per patient with CIA were $5520 (DA) and $5833 (EA). Annual average drug costs for administrations were estimated at $100 (DA) and $301 (EA) for 2014. Per member per year (PMPY) costs for patients with CIA were estimated at $5620 (DA) and $6134 (EA) for 2014. The annual total costs per CIA population (n=1842) were estimated at $10 352 629 (DA) and $11 298 798 (EA) for 2014. Conclusion: DA Q3W has the potential to provide cost savings over EA QW in terms of annual average drug cost per patient with CIA ($313 savings), PMPY costs for patients with CIA ($514 savings), and total cost per CIA population ($946 169 savings).

Abstract
BACKGROUND The impact of erythropoiesis-stimulating agents in chemotherapy-induced anemia has been a constant topic of debate over recent years. We prospectively assessed the efficacy of epoetin beta (Epo-b) in improving hemoglobin (Hb) levels and outcome in patients within an open label, randomized clinical phase II trial with advanced or metastatic gastric/esophagogastric cancer. METHODS Previously untreated patients were randomized to receive 3-weekly cycles of capecitabine (1000 mg/m(2) bid) for 14 days plus on day 1 either irinotecan 250 mg/m(2) or cisplatin 80 mg/m(2). Epo-b (30000 IU once weekly) was initiated in patients with Hb <11 g/dl and continued until Hb ≥12 g/dl was reached. If after 4 weeks the Hb increase was <0.5 g/dl, Epo-b was increased to 30000 IU, twice weekly. RESULTS Of 118 patients enrolled, 32 received Epo-b treatment; of these, 65 % achieved an increase in Hb levels of at least 2 g/dl, with 74 % achieving the target Hb of ≥12 g/dl. Within the study population, patients receiving Epo-b showed better overall survival (median 14.5 vs. 8.0 months, P = 0.056) as well as a significantly improved disease control rate (78 vs. 55 %, P = 0.025). Patients in the irinotecan group profited significantly (P < 0.05) in terms of progression-free survival and overall survival under Epo-b treatment (median 6.5 vs 4.1 months and median 15.4 vs 8.4 months, respectively). CONCLUSIONS Epo-b was effective in raising Hb levels in patients with advanced esophagogastric cancer. Patients receiving Epo-b had a significantly increased response to chemotherapy and a clear trend to improved survival.

Abstract
BACKGROUND Anaemia associated with cancer and cancer therapy is an important clinical factor in the treatment of malignant diseases. Therapeutic alternatives are recombinant human erythropoiesis stimulating agents (ESAs) and red blood cell transfusions. OBJECTIVES To assess the effects of ESAs to either prevent or treat anaemia in cancer patients. SEARCH METHODS This is an update of a Cochrane review first published in 2004. We searched the Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE and other databases. Searches were done for the periods 01/1985 to 12/2001 for the first review, 1/2002 to 04/2005 for the first update and to November 2011 for the current update. We also contacted experts in the field and pharmaceutical companies. SELECTION CRITERIA Randomised controlled trials on managing anaemia in cancer patients receiving or not receiving anti-cancer therapy that compared the use of ESAs (plus transfusion if needed). DATA COLLECTION AND ANALYSIS Several review authors assessed trial quality and extracted data. One review author assessed quality assessment and extracted data, a second review author checked for correctness. MAIN RESULTS This update of the systematic review includes a total of 91 trials with 20,102 participants. Use of ESAs significantly reduced the relative risk of red blood cell transfusions (risk ratio (RR) 0.65; 95% confidence interval (CI) 0.62 to 0.68, 70 trials, N = 16,093). On average, participants in the ESAs group received one unit of blood less than the control group (mean difference (MD) -0.98; 95% CI -1.17 to -0.78, 19 trials, N = 4,715). Haematological response was observed more often in participants receiving ESAs (RR 3.93; 95% CI 3.10 to 3.71, 31 trials, N = 6,413). There was suggestive evidence that ESAs may improve Quality of Life (QoL). There was strong evidence that ESAs increase mortality during active study period (hazard ratio (HR) 1.17; 95% CI 1.06 to 1.29, 70 trials, N = 15,935) and some evidence that ESAs decrease overall survival (HR 1.05; 95% CI 1.00 to 1.11, 78 trials, N = 19,003). The risk ratio for thromboembolic complications was increased in patients receiving ESAs compared to controls (RR 1.52, 95% CI 1.34 to 1.74; 57 trials, N = 15,498). ESAs may also increase the risk for hypertension (fixed-effect model: RR 1.30; 95% CI 1.08 to 1.56; random-effects model: RR 1.12; 95% CI 0.94 to 1.33, 31 trials, N = 7,228) and thrombocytopenia/haemorrhage (RR 1.21; 95% CI 1.04 to 1.42; 21 trials, N = 4,507). There was insufficient evidence to support an effect of ESA on tumour response (fixed-effect RR 1.02; 95% CI 0.98 to 1.06, 15 trials, N = 5,012). AUTHORS' CONCLUSIONS ESAs reduce the need for red blood cell transfusions but increase the risk for thromboembolic events and deaths. There is suggestive evidence that ESAs may improve QoL. Whether and how ESAs affects tumour control remains uncertain. The increased risk of death and thromboembolic events should be balanced against the potential benefits of ESA treatment taking into account each patient's clinical circumstances and preferences. More data are needed for the effect of these drugs on quality of life and tumour progression. Further research is needed to clarify cellular and molecular mechanisms and pathways of the effects of ESAs on thrombogenesis and their potential effects on tumour growth.

Abstract
OBJECTIVES The CHOICE study was a prospective, multicentre, observational study designed to assess levels of adherence in current clinical practice to the European product label and EORTC guidelines for the treatment of chemotherapy-induced anaemia (CIA) with darbepoetin alfa (DA). Here we present data split by tumour types: breast, colorectal, ovarian and lung. METHODS Haemoglobin (Hb) levels and red blood cell transfusion requirements were evaluated among patients with solid tumours in 11 European countries. The primary outcome measure was the proportion of patients with a target Hb level of ≥10-≤12 g/dL. RESULTS The full analysis set included 1887 patients (mean ± SD 62.4 ± 11.4 years); 1585 (84%) had a current disease stage of ≥3. Common chemotherapy regimens were non-platinum + non-taxane based (n = 696 [37%]) or platinum + non-taxane based (n = 660 [35%]). Breast cancer (n = 575): The mean ± SD Hb level at baseline was 9.9 ± 0.8 g/dL (n = 568). Target Hb level was reached by 187 (55%) patients. Colorectal cancer (n = 310): At baseline the mean ± SD Hb level was 9.8 ± 0.8 g/dL (n = 306). Target Hb level was reached by 107 patients (56%). Ovarian cancer (n = 301): The mean ± SD Hb level at baseline was 9.7 ± 0.8 g/dL (n = 294). Target Hb level was reached by 81 patients (44%). Lung cancer (n = 701): At baseline the mean ± SD Hb level was 9.8 ± 0.9 g/dL (n = 692). Target Hb level was reached by 142 patients (39%). SAFETY Five severe or life-threatening adverse drug reactions were seen (three patients with breast cancer, one patient with colorectal cancer and one patient with ovarian cancer). LIMITATIONS Potential bias could not be excluded due to the study's observational nature. CONCLUSIONS This study demonstrates that the recommendations are adhered to in clinical practice, with the mean starting Hb level <10 g/dL irrespective of tumour type. Furthermore, DA is likely to be effective and well tolerated for the treatment of CIA in patients with breast, colorectal, ovarian or lung cancer.

Abstract
OBJECTIVES The CHOICE study was a prospective, multicentre, observational study designed to assess the level of adherence in current clinical practice to the European product label and the EORTC guidelines for the treatment of chemotherapy-induced anaemia with darbepoetin alfa (DA). METHODS Hb levels and red blood cell (RBC) transfusion requirements were evaluated among 1900 patients with solid tumours in 11 European countries. The primary outcome measure was the proportion of patients with a target Hb level of ≥10-≤12 g/dL after 9 weeks' DA treatment. RESULTS The full analysis set (FAS) comprised 1887 patients (mean ± SD age 62.4 ± 11.4 years) divided into categories by baseline Hb < 9 g/dL (n = 281); 9-<10 g/dL (n = 770); 10-<11 g/dL (n = 695); ≥11 g/dL (n = 114). The proportion of patients who remained on the study at week 9 achieving the target Hb level was 37% (n = 60), 48% (n = 217), 54% (n = 210) and 38% (n = 23) in the subgroups with a baseline Hb level of <9 g/dL, 9-<10 g/dL, 10-<11 g/dL and ≥11 g/dL, respectively. In the <9 g/dL, 9-<10 g/dL, 10-<11 g/dL and ≥11 g/dL subgroups of the FAS, the number of patients maintaining Hb levels ≥10 g/dL after their first achievement of an Hb value of 10 g/dL was 95 (34%), 372 (48%), 476 (68%) and 87 (76%), respectively. The Kaplan-Meier percentages of patients who required an RBC transfusion from week 5 until end of treatment period were: 29%, 20%, 12% and 17% in the <9 g/dL, 9-<10 g/dL, 10-<11 g/dL and ≥11 g/dL subgroups, respectively. Kaplan-Meier percentages of patients reaching an Hb level of >13 g/dL were 10%, 9%, 21% and 29%, respectively. Potential bias could not be excluded due to the study's observational nature. CONCLUSIONS DA initiation and target Hb ranges adhered to current guidelines in the majority of patients. Furthermore, this study demonstrates faster achievement of the target range and reduced transfusion requirements are associated with initiation of DA at Hb levels of 9-<10 g/dL and 10-<11 g/dL rather than <9 g/dL.

Abstract
Anemia is a common, but underestimated and undertreated, complication of patients with cancer receiving chemo- or radiotherapy, and negatively affects their quality of life (QoL). Erythropoietic proteins (EPS) offer an effective treatment of cancer anemia and ameliorate QoL, although their use requires the correct targeting of hemoglobin increase to avoid thromboembolic complications. Currently the effort is focused on offering patients this effective treatment with reduced frequency of administration. Higher weekly single doses of recombinant human Epo (rHuEpo) either alpha or beta, instead of three times per week, have been proposed for the treatment. The pharmacokinetic and pharmacodynamic characteristics of the hyperglycosylated protein darbepoetin alpha permit even longer inter vals between administrations. Every other week or every three weeks schedules have shown results (erythropoietic response, reduction of transfusion requirements, and improvement of QoL) comparable with those of weekly rHuEpo.

Abstract
OBJECTIVE To evaluate adherence to European Organisation for Research and Treatment of Cancer (EORTC) and European Summary of Product Characteristic (SmPC) guidance on recommended haemoglobin (Hb) values in routine clinical practice use of darbepoetin alfa (DA) in cancer patients internationally. METHODS This multicentre, prospective, observational study assessed DA use in 11 European countries. This interim analysis (IA) included ∼1300 breast, colorectal, ovarian or lung cancer patients receiving DA during any chemotherapy cycle. Hb level and red blood cell (RBC) transfusion requirement data were collected. RESULTS Of the 1290 patients (mean [SD] age 62.5 [11.1] years) included in this IA full analysis set, 499 had lung, 387 breast, 192 colorectal and 212 ovarian cancer. Mean baseline Hb levels were <10 g/dL. At week 9, 426 (33%) patients had a Hb level of 10-12 g/dL, 165 (13%) of >12 g/dL, 226 (18%) of <10 g/dL and 473 (37%) had missing Hb values. 54% of the 672 patients still on the study at week 9 with available Hb values had Hb values of 10-12 g/dL. For patients with a baseline Hb of <10 g/dL, the Kaplan-Meier (K-M) percentage of patients with Hb levels ≥10 g/dL from week 1 to end of treatment period (EOTP) was 86%. For these patients, the K-M% of patients with Hb levels >13 g/dL from week 1 to EOTP was 10%. The K-M% of patients requiring RBC transfusions from week 5 to EOTP was 26% for all patients. Seven patients reported treatment-related non-serious adverse drug reactions, four were thromboses. CONCLUSIONS This IA suggests most patients were treated according to European SmPC guidance. Hb evolution during the study is consistent with data from clinical trials, implying DA is effective in increasing Hb levels in chemotherapy-induced anaemia patients. Hb levels >13 g/dL were infrequent. Limitations are related to the observational nature of this study.

Abstract
Darbepoetin alfa, an erythropoiesis-stimulating agent (ESA), is used in cancer patients as a supportive care for anemia. For small-cell lung cancer (SCLC), several studies have shown that the administration of ESAs does not affect survival but decreases the need for blood transfusions and improves the quality of life (QOL) of patients receiving chemotherapy. The present randomized phase II study assessed the feasibility, efficacy, and safety of the administration of darbepoetin alfa to patients with SCLC receiving dose-dense (every 2 weeks) standard chemotherapy consisting of carboplatin plus etoposide, pegfilgrastim prophylactically. Seventy-four chemotherapy-naive patients with limited or extensive SCLC received combination chemotherapy for 6 cycles, and half of the patients additionally received darbepoetin to achieve a target hemoglobin concentration of 12-13 g/dL. The primary study outcome, progression-free survival, showed no difference between the 2 arms of the study. Among the secondary endpoints, objective response was similar in the presence and absence of darbepoetin (best response rates = 75.0% vs. 77.8%). Likewise, 1-year survival rates were not different between the 2 treatment arms (40.1% vs. 45.9%). There were no significant differences in grade 3/4 toxicities. As expected, the need for blood transfusions differed significantly: 19.4% of patients in the darbepoetin arm received transfusions versus 38.9% in the control arm. Analysis of European Organization for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ-C30) scales at different time points showed that the darbepoetin group's QOL was significantly better for certain readouts and never significantly worse than that of the control group. Thus, the combination of darbepoetin alfa with dose-dense carboplatin plus etoposide was feasible and well tolerated. Addition of darbepoetin alfa to chemotherapy lowered the need for blood transfusions and did not affect measures of survival and objective response.

Abstract
BACKGROUND Erythropoiesis-stimulating agents (ESAs) reduce anemia in cancer patients and may improve quality of life, but there are concerns that ESAs might increase mortality. OBJECTIVES Our objectives were to examine the effect of ESAs and identify factors that modify the effects of ESAs on overall survival, progression free survival, thromboembolic and cardiovascular events as well as need for transfusions and other important safety and efficacy outcomes in cancer patients. SEARCH STRATEGY We searched the Cochrane Library, Medline, Embase and conference proceedings for eligible trials. Manufacturers of ESAs were contacted to identify additional trials. SELECTION CRITERIA We included randomized controlled trials comparing epoetin or darbepoetin plus red blood cell transfusions (as necessary) versus red blood cell transfusions (as necessary) alone, to prevent or treat anemia in adult or pediatric cancer patients with or without concurrent antineoplastic therapy. DATA COLLECTION AND ANALYSIS We performed a meta-analysis of randomized controlled trials comparing epoetin alpha, epoetin beta or darbepoetin alpha plus red blood cell transfusions versus transfusion alone, for prophylaxis or therapy of anemia while or after receiving anti-cancer treatment. Patient-level data were obtained and analyzed by independent statisticians at two academic departments, using fixed-effects and random-effects meta-analysis. Analyses were according to the intention-to-treat principle. Primary endpoints were on study mortality and overall survival during the longest available follow-up, regardless of anticancer treatment, and in patients receiving chemotherapy. Tests for interactions were used to identify differences in effects of ESAs on mortality across pre-specified subgroups. The present review reports only the results for the primary endpoint. MAIN RESULTS A total of 13933 cancer patients from 53 trials were analyzed, 1530 patients died on-study and 4993 overall. ESAs increased on study mortality (combined hazard ratio [cHR] 1.17; 95% CI 1.06-1.30) and worsened overall survival (cHR 1.06; 95% CI 1.00-1.12), with little heterogeneity between trials (I(2) 0%, p=0.87 and I(2) 7.1%, p=0.33, respectively). Thirty-eight trials enrolled 10441 patients receiving chemotherapy. The cHR for on study mortality was 1.10 (95% CI 0.98-1.24) and 1.04; 95% CI 0.97-1.11) for overall survival. There was little evidence for a difference between trials of patients receiving different cancer treatments (P for interaction=0.42). AUTHORS' CONCLUSIONS ESA treatment in cancer patients increased on study mortality and worsened overall survival. For patients undergoing chemotherapy the increase was less pronounced, but an adverse effect could not be excluded.

Abstract
BACKGROUND Anemia in patients with solid tumors is a common problem that is associated with impaired exercise capacity, increased fatigue, and lower quality of life (QoL). Erythropoiesis-stimulating agents (ESAs) have been shown to improve these outcomes; however, it is unknown if additional benefits can be achieved with aerobic exercise training. METHODS We conducted a single-center, prospective, randomized, controlled trial in 55 mild-to-moderately anemic patients with solid tumors. Patients were randomized to either darbepoetin alfa alone (DAL, n = 29) or darbepoetin alfa plus aerobic exercise training (DEX; n = 26). The DEX group performed aerobic exercise training three times per week at 60%-100% of baseline exercise capacity for 12 weeks. The primary endpoint was QoL assessed by the Functional Assessment of Cancer Therapy-Anemia scale. Secondary endpoints were fatigue, cardiorespiratory fitness (VO(2peak)), hemoglobin (Hb) response, and darbepoetin alfa dosing. RESULTS Intention-to-treat analyses indicated significant improvements in QoL and fatigue in both groups over time but there were no between-group differences. The DEX group had a significantly greater VO(2peak) than the DAL group (mean group difference, +3.0 ml/kg per minute; 95% confidence interval, 1.2-4.7; p = .001) and there were borderline significant differences in favor of the DEX group for Hb response and darbepoetin alfa dosing. CONCLUSIONS Aerobic exercise training did not improve QoL or fatigue beyond the established benefits of DAL but it did result in favorable improvements in exercise capacity and a more rapid Hb response with lower dosing requirements. Our results may be useful to clinicians despite the more recent restrictions on the indications for ESAs.

Abstract
Erythropoietin is a hypoxia-induced cytokine that stimulates erythropoiesis through the promotion of erythroid precursor cell proliferation and differentiation. Recent evidence supports that erythropoietin has a broad spectrum of tissue protecting actions affecting other systems than hemopoietic. Lately, research has focused on the nonhemopoietic effects of erythropoietin against tissue ischemia due to the unexpected observations of erythropoietin receptor expression by various cells, such as endothelial cells, neuronal cells, cardiac myocytes, and vascular smooth muscle cells. It has been shown that erythropoietin exerts its cardioprotective action during cardiac ischemic injury through reducing the infract size and enhancing new vessel formation over a longer time frame. Erythropoietin plays a crucial role in neuroprotection in many types of ischemic injury in the central and the peripheral nervous system. It is also strongly believed that erythropoietin exhibits a critical role in many other disorders that are pathogenetically related to acute tissue ischemia. This article reviews the proposed implications of erythropoietin in tissue ischemia and discusses the possible mechanisms for this action along with its potential therapeutic applications.

Abstract
AIM: To evaluate the efficacy of Myelophil, an extract containing Astragali Radix and Salviae Radix, for reducing complications induced by 5-fluorouracil (5-FU) in a gastrointestinal cancer model.
METHODS: We injected 5-FU into mice and then administered Myelophil to examine the ability of the drug to treat the side effects of 5-FU in mice. Peripheral blood counts, histological examinations, and colony-forming assays of bone marrow were conducted, followed by swimming tests and assessment of survival times.
RESULTS: Myelophil restored red and white blood cells and platelets in blood, and recovered cell density in bone marrow to levels comparable to those observed within the control group. In addition, Myelophil significantly increased colony-forming unit granulocyte-macrophage (CFU-GM) and CFU-erythroid (CFU-E) compared to the control group. We confirmed that interleukin-3 gene expression was upregulated by Myelophil in spleen cells. Myelophil administration also doubled the survival rate of mice that were severely myelosuppressed as a result of 5-FU injection at a lethal dose of 70%. Finally, the swimming performance of mice significantly improved as a result of Myelophil treatment.
CONCLUSION: These results provide experimental evidence in support of clinical applications of Myelophil to minimize 5-FU-induced myelosuppression and improve general post-chemotherapy health.

Abstract
Purpose. To discuss the clinical issues we addressed in the development of our institutional guidelines regarding the assessment of iron stores for cancer- and treatment-related anemia and the administration of parenteral iron with erythropoiesis-stimulating agents (ESAs). Data sources. Studies published from January 1995 to August 2007 were identified by computer searches of Medline and hand searching of bibliographies of the articles identified via the computer searches. The current clinical practice guidelines were identified by computer searches of the web sites for national professional organizations that represent health care professionals who treat patients with cancer. Results of data analysis. Hematopoietic responses demonstrate that epoetin alfa and darbepoetin alfa provide similar outcomes for patients with chemotherapy-induced anemia (CIA); however, up to 50% of patients receiving these agents fail to adequately respond. Functional iron deficiency defined as a state of iron-restricted erythropoiesis is likely the primary contributor to the lack of response. Hematopoietic responses following ESA therapy with parenteral iron are substantially higher compared to response with no or oral iron. Conclusions. Iron stores should be assessed in all patients with cancer- or treatment-related anemia and parenteral iron should be administered to patients receiving ESA therapy to improve hematopoietic response. A unique algorithm that summarizes our institutional guidelines to assess iron stores and administer parenteral iron with ESA therapy in patients with CIA is included.

Abstract
Purpose The Breast Cancer—Anemia and the Value of Erythropoietin (BRAVE) study evaluated whether epoetin beta would improve survival in patients with metastatic breast cancer (MBC). Patients and Methods BRAVE was an open-label, randomized, multicenter study in patients with MBC treated with anthracycline- and/or taxane-based chemotherapy. Patients (hemoglobin [Hb] < 12.9 g/dL) were randomly assigned (1:1) to epoetin beta 30,000 U subcutaneously once weekly or control for 24 weeks. The primary efficacy variable was overall survival. Secondary efficacy outcomes included progression-free survival, transfusion- and severe anemia–free survival, Hb response, safety, and quality of life (QoL). Results After 18 months of follow-up, 62 (27%) of 231 patients survived with epoetin beta therapy and 63 (27%) of 232 with control. No difference was detected in overall survival (hazard ratio [HR] = 1.07; 95% CI, 0.87 to 1.33, P = .522) or progression-free survival (HR = 1.07; 95% CI, 0.89 to 1.30, P = .448). There was a statistically significant benefit on transfusion- and severe anemia–free survival compared with control (HR = 0.59; P = .0097). Median Hb level increased with epoetin beta (11.7 g/dL at baseline to 13.3 g/dL at 24 weeks) but did not change with control (11.5 v 11.4 g/dL). Patients receiving epoetin beta experienced more thromboembolic events (TEEs) compared with controls (13% v 6%; P = .012) with no difference in serious TEEs (4% v 3%). Epoetin beta did not significantly improve QoL in this study where patients had a high baseline Hb value. Conclusion In patients with MBC receiving chemotherapy and initial Hb less than 12.9 g/dL, epoetin beta increased Hb. No difference was detected in overall survival. Because of its superiority design, this study cannot, however, exclude clinically important differences in survival with absolute certainty.

Abstract
Chemotherapy-induced anaemia (CIA) is a significant source of morbidity in patients receiving treatment for cancer. There are three products currently available for the treatment of CIA: epoetin alfa, epoetin beta and darbepoetin alfa. Several organisations have published recommendations for the use of these agents. Several randomised, controlled trials have been conducted comparing the most popular dosing regimens of epoetin alfa and darbepoetin alfa, with conflicting results. Information regarding survival and adverse event data related to these agents continues to create debate. This review considers four new agents that are under development for the treatment of CIA.
