Abstract
BACKGROUND Iron supplementation improves the erythropoiesis-stimulating agents' (ESAs) response in chemotherapy-related anemia. The primary aim of our study is to assess the efficacy of sucrosomial iron, a new oral iron formulation, in cancer patients with chemotherapy-induced anemia treated with ESAs. The secondary objectives included the efficacy into two subgroups of patients (iron replete and functional iron deficiency) between the two study arms, safety and the effect on transfusion need. METHODS In this randomized, multicentre, open-label, phase III clinical trial, 60 cancer patients were enrolled. Each patient was randomly assigned (1:1) to receive 12 weeks of oral sucrosomial iron at the dose of 30 mg daily in combination with ESAs or no supplementation to ESA treatment. The endpoint considered for efficacy was the proportion of patients achieving complete hematological response at 12 weeks (increase in Hb > 2 g/dL from baseline, without RBC transfusions in the previous 28 days or achieving Hb ≥ 12 g/dL). RESULTS There was a statistically significant association between oral sucrosomial iron supplementation in combination with ESAs and the achievement of a complete hematological response. This response was achieved within 12 weeks by 31% of patients in the control group and by 52% of patients supplemented with oral sucrosomial iron. A trend of greater response in sucrosomial iron arm was found in both subgroups. No difference was observed about safety and transfusion need. CONCLUSIONS Sucrosomial iron is well tolerated and its combination with ESAs improves the hematological response in cancer patients with chemotherapy-related anemia. TRIAL REGISTRATION NUMBER AND DATE OF REGISTRATION This study has been reviewed by the Institutional Ethics Committee of the IRCCS Policlinico San Matteo Foundation, Pavia, Italy (28/04/2015; prot. N. 20,150,002,059), and by the Institutional Ethics Committee of the other Italian oncological centers involved in this study.

Abstract
Erythropoisis stimulating agent (ESA) use was addressed in Food and Drug Administration (FDA) Oncology Drug Advisory Committee (ODAC) meetings between 2004 and 2008. FDA safety-focused regulatory actions occurred in 2007 and 2008. In 2007, black box warnings advised of early death and venous thromboembolism (VTE) risks with ESAs in oncology. In 2010, a Risk Evaluation Strategies (REMS) was initiated, with cancer patient consent that mortality and VTE risks were noted with ESAs. We report warnings and REMS impacts on ESA utilization among Veterans Administration (VA) cancer patients with chemotherapy-induced anemia (CIA). Data were from Veterans Affairs database (2003–2012). Epoetin and darbepoetin use were primary outcomes. Segmented linear regression was used to estimate changes in ESA use levels and trends, clinical appropriateness, and adverse events (VTEs) among chemotherapy-treated cancer patients. To estimate changes in level of drug prescription rate after policy actions, model-specific indicator variables as covariates based on specific actions were included. ESA use fell by 95% and 90% from 2005, for epoetin and darbepoetin, from 22% and 11%, respectively, to 1% and 1%, respectively, among cancer patients with CIA, respectively (p<0.01). Following REMS in 2010, mean hematocrit levels at ESA initiation decreased from 30% to 21% (p<0.01). Black box warnings preceded decreased ESA use among VA cancer patients with CIA. REMS was followed by reduced hematocrit levels at ESA initiation. Our findings contrast with privately- insured and Medicaid insured cancer patient data on chemotherapy-induced anemia where ESA use decreased to 3% to 7% by 2010–2012. By 2012, the era of ESA administration to VA to cancer patients had ended but the warnings remain relevant and significant. In 2019, oncology/hematology national guidelines (ASCO/ASH) recommend that cancer patients with chemotherapy-induced anemia should receive ESAs or red blood cell transfusions after risk-benefit evaluation.

Venous Thromboembolism in Cancer Patients on Simultaneous and Palliative Care. Cancers (Basel) 2020; 12:cancers12051167.

Abstract
Simultaneous care represents the ideal integration between early supportive and palliative care in cancer patients under active antineoplastic treatment. Cancer patients require a composite clinical, social and psychological management that can be effective only if care continuity from hospital to home is guaranteed and if such a care takes place early in the course of the disease, combining standard oncology care and palliative care. In these settings, venous thromboembolism (VTE) represents a difficult medical challenge, for the requirement of acute treatments and for the strong impact on anticancer therapies that might be delayed or, even, totally discontinued. Moreover, cancer patients not only display high rates of VTE occurrence/recurrence but are also more prone to bleeding and this forces clinicians to optimize treatment strategies, balancing between hemorrhages and thrombus formation. VTE prevention is, therefore, regarded as a double-edged sword. Indeed, while on one hand the appropriate use of antithrombotic agents can reduce VTE occurrence, on the other it significantly increases the bleeding risk, especially in the frail patients who present with multiple co-morbidities and poly-therapy that can interact with anticoagulant drugs. For these reasons, thromboprophylaxis should start while active cancer treatment is ongoing, according to a simultaneous care model in a patient-centered perspective.

Abstract
Cancer patients have an increased risk of thrombosis. The development of cancer thrombosis is dependent on a number of factors including cancer type, stage, various biologic markers, and the use of central venous catheters. In addition, cancer treatment itself may increase thrombotic risk. Tamoxifen increases the risk of venous thromboembolism (VTE) by two- to sevenfold, while an impact on risk of arterial thrombosis is uncertain. Immunomodulatory imide drugs (IMiDs) such as thalidomide and lenalidomide increase the risk of VTE in patients with multiple myeloma (MM) by about 10-40% when given in combination with glucocorticoids or other chemotherapy agents; the risk of VTE in MM patients treated with IMiD-containing regimens necessitates that such patients receive thromboprophylaxis with aspirin, low-molecular-weight heparin, or warfarin. Among cytotoxic chemotherapy agents, cisplatin, and to a lesser extent fluorouracil, has been described in association with thrombosis. L-asparaginase in treatment of acute lymphoblastic leukemia is significantly associated with increased thrombosis particularly affecting the CNS, which may be due to acquired antithrombin deficiency; at some centers, plasma infusions or antithrombin replacement is used to mitigate this. Bevacizumab, an inhibitor of vascular endothelial growth factor, increases arterial and possibly venous thrombotic risk, although the literature is conflicting about the latter. Supportive care agents in cancer care, such as erythropoiesis-stimulating agents, granulocyte colony stimulating factor, and steroids, also have some impact on thrombosis. This review summarizes the mechanisms by which these and other therapies modulate thrombotic risks and how such risks may be managed.

A systematic review and meta-analysis of randomized controlled trials on the effect of erythropoiesis-stimulating agents in cancer patients. PLoS One 2017; 12:e0189309. [PMID: 29228059 PMCID: PMC5724886 DOI: 10.1371/journal.pone.0189309] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2017] [Accepted: 11/22/2017] [Indexed: 12/05/2022] Open
Abstract
Since 2010, the European Medicines Agency (EMA) has provided access to clinical study reports (CSRs). We requested CSRs for randomized controlled trials (RCTs) of erythropoiesis-stimulating agents (ESAs) in cancer patients from EMA and identified RCT publications with literature searches. We assessed CSR availability and completeness, the impact of unreported and unpublished data obtained from CSRs on the effects of ESAs on quality of life (QoL) of cancer patients, and discrepancies between data reported in the public domain and in CSRs. We used random-effects meta-analyses to evaluate the effect of ESAs on QoL measured with Functional Assessment of Cancer Therapy-Anemia (FACT-An), FACT-Fatigue (FACT-F) and FACT-Anemia Total (FACT-An Total) stratified by data source and the impact of discrepancies on QoL, mortality, adverse events, and clinical effectiveness outcomes. We identified 94 eligible RCTs; CSRs or other study documentation were available for 17 (18%) RCTs at EMA. Median report length was 1,825 pages (range 72-14,569). Of 180 outcomes of interest reported in the EMA documentation, 127 (71%) were publicly available. For 80 of those (63%) we noted discrepancies, but these had little impact on the pooled effect estimates. Of 27 QoL outcomes reported in the CSRs, 17 (63%) were unpublished. Including six unpublished comparisons (pooled mean difference [MD] 0.20; 95% confidence interval [CI] -1.93, 2.33) reduced the pooled effect of ESAs for FACT-An from MD 5.51 (95% CI 4.20, 6.82) in published data to MD 3.21 (95% CI 1.38, 5.03), which is below a clinically important difference (defined as MD ≥4). Effects were similar for FACT-F and FACT-An Total. Access to CSRs from EMA reduced reporting biases for QoL outcomes. However, EMA received documentation for a fraction of all RCTs on effects of ESAs in cancer patients. Additional efforts by other agencies and institutions are needed to make CSRs universally available for all RCTs.

Abstract
Postoperative cognitive dysfunction (POCD) may be driven by transference of the innate immune response to the brain after aseptic surgical damage. Macrophages are key mediators of innate immunity that can display a pro-inflammatory M1 phenotype or an anti-inflammatory M2 phenotype. Erythropoietin (EPO) is a hematopoietic hormone that exerts anti-inflammatory effects by influencing macrophage function. We hypothesized that EPO would prevent POCD by promoting macrophage phenotype switching to the M2 phenotype post-surgery. To evaluate the effects of EPO on POCD and macrophage polarization post-surgery, we administered EPO (5,000 U/kg) with or without an arginase inhibitor (amino-6-boronohexanoic acid, 10 mg/kg) to ICR mice before and after abdominal surgery. Forty-eight hours post-surgery, we assessed memory, synapse function, and macrophage/microglial phenotypes in the spleen and hippocampus. We also investigated M1/M2 phenotypes in RAW264.7 and BV2 cells stimulated with lipopolysaccharide and interferon-γ (M1 inducers) in the presence or absence of EPO. EPO prevented POCD, decreased surgery-related synaptic dysfunction, and attenuated pro-inflammatory cytokine generation in the hippocampus. Moreover, EPO suppressed M1-related genes expression and promoted M2 genes expression in the spleen and hippocampus post-surgery. Furthermore, EPO decreased the proportions of macrophages/microglia expressing an M1 surface marker (CD40) and increased those expressing an M2 surface marker (CD206). Arginase inhibition abolished the beneficial effects of EPO on POCD. In vitro, EPO treatment promoted switching of RAW264.7 and BV2 cells stimulated with M1 inducers to an M2 phenotype. In conclusion, EPO prevents POCD by promoting macrophage phenotype switching toward the M2 phenotype.

Abstract
BACKGROUND Fatigue and unintentional weight loss are two of the commonest symptoms experienced by people with advanced progressive illness. Appropriate interventions may bring considerable improvements in function and quality of life to seriously ill people and their families, reducing physical, psychological and spiritual distress. OBJECTIVES To conduct an overview of the evidence available on the efficacy of interventions used in the management of fatigue and/or unintentional weight loss in adults with advanced progressive illness by reviewing the evidence contained within Cochrane reviews. METHODS We searched the Cochrane Database of Systematic Reviews (CDSR) for all systematic reviews evaluating any interventions for the management of fatigue and/or unintentional weight loss in adults with advanced progressive illness (The Cochrane Library 2010, Issue 8). We reviewed titles of interest by abstract. Where the relevance of a review remained unclear we reached a consensus regarding the relevance of the participant group and the outcome measures to the overview. Two overview authors extracted the data independently using a data extraction form. We used the measurement tool AMSTAR (Assessment of Multiple SysTemAtic Reviews) to assess the methodological quality of each systematic review. MAIN RESULTS We included 27 systematic reviews (302 studies with 31,833 participants) in the overview. None of the included systematic reviews reported quantitative data on the efficacy of interventions to manage fatigue or weight loss specific to people with advanced progressive illness. All of the included reviews apart from one were deemed of high methodological quality. For the remaining review we were unable to ascertain the methodological quality of the research strategy as it was described. None of the systematic reviews adequately described whether conflict of interests were present within the included studies. Management of fatigueAmyotrophic lateral sclerosis/motor neuron disease (ALS/MND) - we identified one systematic review (two studies and 52 participants); the intervention was exercise.Cancer - we identified five systematic reviews (116 studies with 17,342 participants); the pharmacological interventions were eicosapentaenoic acid (EPA) and any drug therapy for the management of cancer-related fatigue and the non pharmacological interventions were exercise, interventions by breast care nurses and psychosocial interventions.Chronic obstructive pulmonary disease (COPD) - we identified three systematic reviews (59 studies and 4048 participants); the interventions were self management education programmes, nutritional support and pulmonary rehabilitation.Cystic fibrosis - we identified one systematic review (nine studies and 833 participants); the intervention was physical training.Human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) - we identified two systematic reviews (21 studies and 748 participants); the interventions were progressive resistive exercise and aerobic exercise.Multiple sclerosis (MS) - we identified five systematic reviews (23 studies and 1502 participants); the pharmacological interventions were amantadine and carnitine. The non pharmacological interventions were diet, exercise and occupational therapy.Mixed conditions in advanced stages of illness - we identified one systematic review (five studies and 453 participants); the intervention was medically assisted hydration. Management of weight lossALS/MND - we identified one systematic review but no studies met the inclusion criteria for the systematic review; the intervention was enteral tube feeding.Cancer - we identified three systematic reviews with a fourth systematic review also containing extractable data on cancer (66 studies and 5601 participants); the pharmacological interventions were megestrol acetate and eicosapentaenoic acid (EPA) (this systematic review is also included in the cancer fatigue section above). The non pharmacological interventions were enteral tube feeding and non invasive interventions for patients with lung cancer.COPD - we identified one systematic review (59 studies and 4048 participants); the intervention was nutritional support. This systematic review is also included in the COPD fatigue section.Cystic fibrosis - we identified two systematic reviews (three studies and 131 participants); the interventions were enteral tube feeding and oral calorie supplements.HIV/AIDS - we identified four systematic reviews (42 studies and 2071 participants); the pharmacological intervention was anabolic steroids. The non pharmacological interventions were nutritional interventions, progressive resistive exercise and aerobic exercise. Both of the systematic reviews on exercise interventions were also included in the HIV/AIDS fatigue section.MS - we found no systematic reviews which considered interventions to manage unintentional weight loss for people with a clinical diagnosis of multiple sclerosis at any stage of illness.Mixed conditions in advanced stages of illness - we identified two systematic reviews (32 studies and 4826 participants); the interventions were megestrol acetate and medically assisted nutrition. AUTHORS' CONCLUSIONS There is a lack of robust evidence for interventions to manage fatigue and/or unintentional weight loss in the advanced stage of progressive illnesses such as advanced cancer, heart failure, lung failure, cystic fibrosis, multiple sclerosis, motor neuron disease, Parkinson's disease, dementia and AIDS. The evidence contained within this overview provides some insight into interventions which may prove of benefit within this population such as exercise, some pharmacological treatments and support for self management.Researchers could improve the methodological quality of future studies by blinding of outcome assessors. Adopting uniform reporting mechanisms for fatigue and weight loss outcome measures would also allow the opportunity for meta-analysis of small studies.Researchers could also improve the applicability of recommendations for interventions to manage fatigue and unintentional weight loss in advanced progressive illness by including subgroup analysis of this population within systematic reviews of applicable interventions.More research is required to ascertain the best interventions to manage fatigue and/or weight loss in advanced illness. There is a need for standardised reporting of these symptoms and agreement amongst researchers of the minimum duration of studies and minimum percentage change in symptom experience that proves the benefits of an intervention. There are, however, challenges in providing meaningful outcome measurements against a background of deteriorating health through disease progression. Interventions to manage these symptoms must also be mindful of the impact on quality of life and should be focused on patient-orientated rather than purely disease-orientated experiences for patients. Systematic reviews and primary intervention studies should include the impact of the interventions on standardised validated quality of life measures.

Efficacy and safety of biosimilar epoetin alpha in patients with chronic lymphoid neoplasms and chemotherapy-induced anaemia: An observational, retrospective, monocentric analysis. Hematol Oncol 2017; 36:136-143. [PMID: 28332724 DOI: 10.1002/hon.2412] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2016] [Revised: 02/13/2017] [Accepted: 02/17/2017] [Indexed: 11/12/2022]
Abstract
Epoetin biosimilars are an alternative to originator erythropoietic agents in the treatment of chemotherapy-induced anaemia; however, their effects in patients with lymphoproliferative disorders remain unclear. This analysis examined the response of patients with lymphoproliferative disorders experiencing chemotherapy-induced anaemia to 4- or 8-week treatment with the biosimilar epoetin alpha. Treatment was initiated at first occurrence of haemoglobin (Hb) < 10 g/dL during chemotherapy and was stopped when Hb was >11 g/dL, when chemotherapy was completed, or in case of transfusion dependency. Response to epoetin alpha was defined as an increase in Hb of >1 g/dL or as an Hb > 11 g/dL. Stability was defined as change in Hb of ±1 g/dL, and no response was indicated by a decrease in Hb of >1 g/dL or acquired transfusion dependence. Overall, 65 patients were enrolled (median age 69 years; 47.7% ≥ 70 years old). Mean Hb levels at the initiation of epoetin alpha was 9.3 ± 0.5 g/dL. Mean Hb levels reached 10.7 ± 1.4 and 10.6 ± 1.5 g/dL at weeks 4 and 8, respectively, in patients on first-line chemotherapy and 11.4 ± 1.6 and 9.7 ± 1.3 g/dL in those on a second- or higher-line regimen. Overall, 70.8% of patients responded, 26.1% had stable Hb, and 3.1% did not respond. Delays or interruption of any chemotherapy cycle due to anaemia occurred in 18 patients. The biosimilar epoetin alpha was well tolerated and allowed patients with non-Hodgkin lymphoma or chronic lymphoproliferative disorders to continue their course of chemotherapy by effectively increasing and maintaining adequate concentrations of Hb.

Abstract
Chronic kidney disease (CKD) anemia treatment was revolutionized in the late 1980s with the introduction of recombinant human erythropoietin. This and related erythropoiesis-stimulating agents (ESAs) greatly benefited patients by decreasing debilitating symptoms, improving their quality of life, and freeing them from dependence on blood transfusions with their associated complications such as infections, sensitization impeding transplantation, and secondary iron overload. However, even in the initial studies, untoward effects were noted in patients receiving ESAs, including worsening hypertension, seizures, and dialysis access clotting. Later, increased mortality, malignancy progression and even stroke were reported in renal patients. This review focuses on the safety issues of ESAs in CKD patients.

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.

Abstract
The aim of this study was to investigate the protective effect of erythropoietin (EPO) against acute myocardial injury and its underlying mechanisms. Mice (n=146) were randomly divided in a double-blind manner into four groups, sham, Rocephin, EPO and sepsis, and mortality was observed on the seventh day after cecal ligation and puncture. In addition, a total of 252 rats were randomly divided into three groups, sham, EPO and sepsis, and indicators of cardiac function, inflammatory mediators and serum creatine kinase levels were assessed. Mitochondrial membrane potential, cell apoptosis and nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB) p65 expression levels were detected using flow cytometry. Following intervention with EPO, the mortality rate in mice with sepsis was significantly reduced and the cardiac function of septic rats was significantly improved. In addition, the levels of inflammatory mediators, serum creatine kinase and apoptosis and the myocardial mitochondrial membrane potential and expression of NF-κB p65 in cardiac tissue were all improved following EPO treatment, and the differences between the results for the sepsis and EPO groups were statistically significant (P<0.05). These findings suggest that EPO reduces the myocardial inflammatory response in septic rats, attenuates the reduction in mitochondrial membrane potential and inhibits myocardial cell apoptosis by reducing NF-κB p65 expression, and therefore exerts a protective effect in the myocardium.

Abstract
OBJECTIVE This study aimed to evaluate the impact of darbepoetin alfa (DA) on hemoglobin (Hb) levels and quality of life (QoL) in cancer patients with anemia in current daily practice following several revisions of anemia treatment guidelines. METHODS This was a prospective, multi-center, observational study across Germany in non-myeloid cancer outpatients with chemotherapy-induced anemia treated with DA. Age, sex, cancer type, stage, and therapy, performance status, anemia status and treatment, and Hb concentrations were recorded for up to 18 weeks in a web-based registry. Optional QoL assessments were collected at baseline and at the end of DA treatment. MAIN RESULTS Of 984 eligible patients, 978 had complete anemia data, 492 also had complete QoL data. In the 978 patients, mean age was 64 (standard deviation, SD 12) years, 62% of patients were women. Breast (26%) and gastrointestinal (22%) cancer were most prevalent. Therapy was palliative in 44% of patients and initiated with curative intent in 29%. Mean baseline Hb was 9.5 (SD 0.9) g/dL, which increased by an average of 1.2 g/dL. In 67% of patients Hb increased either to 10-12 g/dL or by ≥2 g/dL; no Hb response was seen in 219 patients (22%); increases of 0 to 1, >1 to 2, and >2 g/dl were seen in 216 (22%), 265 (27%), and 278 (28%) patients, respectively. Anemia treatment did not result in any significant differences of performance status. However, QoL improvements were significantly greater in Hb responders, although a linear relationship with Hb increments was lacking. None of 47 fatal cases was considered related to treatment with DA. CONCLUSION Patients treated with DA in routine clinical practice had increases in Hb and reported improvement in QoL. Due to the uncontrolled design, no conclusions can be made regarding causality to treatment and the clinical relevance of the improvement.

Abstract
BACKGROUND Erythropoiesis-stimulating agents (ESAs) reduce the need for red blood cell transfusions; however, they increase the risk of thromboembolic events and mortality. The impact of ESAs on quality of life (QoL) is controversial and led to different recommendations of medical societies and authorities in the USA and Europe. We aimed to critically evaluate and quantify the effects of ESAs on QoL in cancer patients. METHODS We included data from randomised controlled trials (RCTs) on the effects of ESAs on QoL in cancer patients. Randomised controlled trials were identified by searching electronic data bases and other sources up to January 2011. To reduce publication and outcome reporting biases, we included unreported results from clinical study reports. We conducted meta-analyses on fatigue- and anaemia-related symptoms measured with the Functional Assessment of Cancer Therapy-Fatigue (FACT-F) and FACT-Anaemia (FACT-An) subscales (primary outcomes) or other validated instruments. RESULTS We identified 58 eligible RCTs. Clinical study reports were available for 27% (4 out of 15) of the investigator-initiated trials and 95% (41 out of 43) of the industry-initiated trials. We excluded 21 RTCs as we could not use their QoL data for meta-analyses, either because of incomplete reporting (17 RCTs) or because of premature closure of the trial (4 RCTs). We included 37 RCTs with 10581 patients; 21 RCTs were placebo controlled. Chemotherapy was given in 27 of the 37 RCTs. The median baseline haemoglobin (Hb) level was 10.1 g dl(-1); in 8 studies ESAs were stopped at Hb levels below 13 g dl(-1) and in 27 above 13 g dl(-1). For FACT-F, the mean difference (MD) was 2.41 (95% confidence interval (95% CI) 1.39-3.43; P<0.0001; 23 studies, n=6108) in all cancer patients and 2.81 (95% CI 1.73-3.90; P<0.0001; 19 RCTs, n=4697) in patients receiving chemotherapy, which was below the threshold (≥ 3) for a clinically important difference (CID). Erythropoiesis-stimulating agents had a positive effect on anaemia-related symptoms (MD 4.09; 95% CI 2.37-5.80; P=0.001; 14 studies, n=2765) in all cancer patients and 4.50 (95% CI 2.55-6.45; P<0.0001; 11 RCTs, n=2436) in patients receiving chemotherapy, which was above the threshold (≥ 4) for a CID. Of note, this effect persisted when we restricted the analysis to placebo-controlled RCTs in patients receiving chemotherapy. There was some evidence that the MDs for FACT-F were above the threshold for a CID in RCTs including cancer patients receiving chemotherapy with Hb levels below 12 g dl(-1) at baseline and in RCTs stopping ESAs at Hb levels above 13 g dl(-1). However, these findings for FACT-F were not confirmed when we restricted the analysis to placebo-controlled RCTs in patients receiving chemotherapy. CONCLUSIONS In cancer patients, particularly those receiving chemotherapy, we found that ESAs provide a small but clinically important improvement in anaemia-related symptoms (FACT-An). For fatigue-related symptoms (FACT-F), the overall effect did not reach the threshold for a CID.

Abstract
OBJECTIVES To characterize erythropoiesis-stimulating agent (ESA) usage initiated in hospital outpatient oncology centers that employ weekly (QW) and every-3-week (Q3W) ESA dosing regimens; describe the frequency of ESA dosing, transfusions, hemoglobin determinations, and anemia-related visits between these 2 regimens; and compare the rates at which inpatient ESA doses are administered on QW versus Q3W schedules. METHODS This was a retrospective, observational record review evaluating ESA usage in 641 patients from 8 outpatient oncology clinics throughout the United States. Adult patients who initiated myelosuppressive chemotherapy for a documented solid tumor between August 1, 2007 and June 30, 2009 and received their first 3 consecutive outpatient ESA doses on a QW or Q3W schedule were eligible for study inclusion. During a single course of chemotherapy, ESA administrations were recorded as long as ESA therapy was continued on the initial regimen. ESA doses were captured until termination of ESA therapy, until 9 months had elapsed since the first ESA dose, until the patient was switched to another ESA regimen, or until death. ESA administration during inpatient admissions was also recorded. RESULTS ESA utilization varied between the dosing groups, with fewer ESA doses administered per follow-up month in patients receiving Q3W versus QW ESA therapy (mean, 1 vs 2 doses). Compared to weekly administration, extended-dose ESA therapy also reduced the number of hemoglobin determinations and anemia-related visits without chemotherapy required per follow-up month. Neither the number of transfusions nor the number of packed red blood cell units administered per follow-up month differed between treatment groups. Compared to weekly ESA therapy, Q3W administration reduced costs associated with ESA prescribing and utilization. CONCLUSION Extended-dose ESA therapy (Q3W dosing) may improve practice efficiency and may be associated with reduced frequencies of hemoglobin determinations and ESA doses required. Q3W dosing may also reduce inpatient ESA utilization by reducing the number of ESA doses required for previously maintained outpatients.

Abstract
The hematopoietic growth factor erythropoietin (Epo) circulates in plasma and controls the oxygen carrying capacity of the blood (Fisher. Exp Biol Med (Maywood) 228:1-14, 2003). Epo is produced primarily in the adult kidney and fetal liver and was originally believed to play a role restricted to stimulation of early erythroid precursor proliferation, inhibition of apoptosis, and differentiation of the erythroid lineage. Early studies showed that mice with targeted deletion of Epo or the Epo receptor (EpoR) show impaired erythropoiesis, lack mature erythrocytes, and die in utero around embryonic day 13.5 (Wu et al. Cell 83:59-67, 1995; Lin et al. Genes Dev. 10:154-164, 1996). These animals also exhibited heart defects, abnormal vascular development as well as increased apoptosis in the brain suggesting additional functions for Epo signaling in normal development of the central nervous system and heart. Now, in addition to its well-known role in erythropoiesis, a diverse array of cells have been identified that produce Epo and/or express the Epo-R including endothelial cells, smooth muscle cells, and cells of the central nervous system (Masuda et al. J Biol Chem. 269:19488-19493, 1994; Marti et al. Eur J Neurosci. 8:666-676, 1996; Bernaudin et al. J Cereb Blood Flow Metab. 19:643-651, 1999; Li et al. Neurochem Res. 32:2132-2141, 2007). Endogenously produced Epo and/or expression of the EpoR gives rise to autocrine and paracrine signaling in different organs particularly during hypoxia, toxicity, and injury conditions. Epo has been shown to regulate a variety of cell functions such as calcium flux (Korbel et al. J Comp Physiol B. 174:121-128, 2004) neurotransmitter synthesis and cell survival (Velly et al. Pharmacol Ther. 128:445-459, 2010; Vogel et al. Blood. 102:2278-2284, 2003). Furthermore Epo has neurotrophic effects (Grimm et al. Nat Med. 8:718-724, 2002; Junk et al. Proc Natl Acad Sci U S A. 99:10659-10664, 2002), can induce an angiogenic phenotype in cultured endothelial cells and is a potent angiogenic factor in vivo (Ribatti et al. Eur J Clin Invest. 33:891-896, 2003) and might enhance ventilation in hypoxic conditions (Soliz et al. J Physiol. 568:559-571, 2005; Soliz et al. J Physiol. 583, 329-336, 2007). Thus multiple functions have been identified breathing new life and exciting possibilities into what is really an old growth factor.This review will address the function of Epo in non-hematopoietic tissues with significant emphasis on the brain and heart.

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
PURPOSE Erythropoiesis-stimulating agents can reduce red blood cell transfusion rates in patients developing anemia while receiving chemotherapy. We investigated potential cost savings from reduced transfusion rates in patients starting darbepoetin alfa (DA) at higher versus lower hemoglobin (Hb) levels. METHODS Two systematic literature reviews were performed: transfusion outcomes in patients receiving DA stratified by baseline Hb level and costs of transfusion in Europe. Potential cost savings were calculated by multiplying the difference in transfusion rates between Hb levels by the midpoint of transfusion costs. RESULTS Despite differences in baseline characteristics, treatment duration and analysis technique, the clinical studies (n = 8) showed that fewer transfusions were required when DA was initiated at higher versus lower Hb levels. The economic studies (n = 9) showed that 1 unit of transfusion ranged from <euro>130 to <euro>537 (2010-adjusted values). Cost savings from initiating DA at higher versus lower Hb levels were <euro>503-2,226 (2 units transfused) and <euro>880-3,895 (3.5 units) per ten patients. CONCLUSIONS Transfusion incidence increases with DA initiation at lower Hb levels. Potential cost savings depend on the number of units transfused and cost items included. DA initiation according to guidelines can reduce transfusions and potentially reduce transfusion-associated costs.

Abstract
A common side effect of cancer treatment is bone marrow suppression. The resulting myelosuppression and anemia can cause significant morbidity and mortality for patients. Agents such as granulocyte colony stimulating factors (GCSF) and erythropoietin stimulating agents (ESAs) may be helpful to ameliorate this depression of blood counts; however these agents have risks which also need to be carefully weighed.

Abstract
Traditionally, erythropoietin (EPO) is described as a hematopoietic cytokine, regulating proliferation and differentiation and survival of the erythroid progenitors. The recent finding of new sites of EPO production and the wide spread distribution of EPO receptors (EPO-R) on endothelial cells, cardiomyocytes, renal cells as well as the central and peripheral nervous system raised the possibility that EPO may exert pleiotropic actions on several targets. Indeed studies (mainly preclinical) have documented protective, non-hematopoietic, abilities of EPO in a variety of tissue. However, the data obtained from clinical studies are more skeptical about these properties. This article provides a comprehensive overview of EPO and its derivatives.

Abstract
Venous thromboembolism (VTE) is the second leading cause of death and a major cause of morbidity in patients with cancer. Pharmacologic thromboprophylaxis is recommended in all hospitalized cancer patients without contraindications to anticoagulants. The role of thromboprophylaxis in outpatients undergoing chemotherapy is less certain because of the diversity of the tumor types and their associated risks of VTE and bleeding. Thromboprophylaxis should only be considered in patients at high risk for VTE. Cancer patients with a newly diagnosed VTE should be preferably treated with low-molecular-weight heparin for a minimum of 3-6 months. Treatment duration should be individualized based on the clinical status and stage of the cancer, the risk of recurrent VTE, the risk of bleeding, and personal preference of the patient. Further research is required to assess the role of the new oral anticoagulants (direct Xa and thrombin inhibitors) for this high-risk population.

Abstract
Cancer-related fatigue is the most prevalent cancer symptom, reported in 50%-90% of patients and severely impacts quality of life and functional capacity. The condition remains underreported and often goes untreated. Guidelines suggest screening for fatigue at the initial visit, when the diagnosis of advanced disease is made, and at each chemotherapy session, as well as the identification of treatable contributing factors such as anemia, hypothyroidism, depression and sleep disorders. Brief assessment tools such as the Brief Fatigue Inventory or the Visual Analog Scale may be appropriate in the initial scoring of fatigue severity, but the initial approach to treatment usually requires a more comprehensive assessment, education, and the determination of an individualized treatment plan. Patients with moderate or severe fatigue may benefit from both pharmacological and non-pharmacological interventions, whereas mild fatigue that does not interfere with quality of life can be treated with non-pharmacological measures alone. Non-pharmacological measures that have shown to be promising include cognitive-behavioral interventions such as energy conservation and activity management (ECAM), exercise and perhaps sleep therapy. Many other modalities may be beneficial and can be used on an individual basis, but there is insufficient evidence to promote any single treatment. Pharmacological therapies that have shown to be promising include the psycho-stimulants methylphenidate and dexmethylphenidate, modafinil (in severely fatigued patients only), and erythropoietin-stimulating agents in patients with chemotherapy-associated anemia and hemoglobin levels < 10 g/dL. Recently, our group reported impressive results with the use of the dry extract of Guarana (Paullinia cupana), with no significant side effects and at low cost, for the treatment of physical and mental cancer-related fatigue.

Abstract
BACKGROUND Fatigue and unintentional weight loss are two of the commonest symptoms experienced by people with advanced progressive illness. Appropriate interventions may bring considerable improvements in function and quality of life to seriously ill people and their families, reducing physical, psychological and spiritual distress. OBJECTIVES To conduct an overview of the evidence available on the efficacy of interventions used in the management of fatigue and/or unintentional weight loss in adults with advanced progressive illness by reviewing the evidence contained within Cochrane reviews. METHODS We searched the Cochrane Database of Systematic Reviews (CDSR) for all systematic reviews evaluating any interventions for the management of fatigue and/or unintentional weight loss in adults with advanced progressive illness (The Cochrane Library 2010, Issue 8). We reviewed titles of interest by abstract. Where the relevance of a review remained unclear we reached a consensus regarding the relevance of the participant group and the outcome measures to the overview. Two overview authors extracted the data independently using a data extraction form. We used the measurement tool AMSTAR (Assessment of Multiple SysTemAtic Reviews) to assess the methodological quality of each systematic review. MAIN RESULTS We included 27 systematic reviews (302 studies with 31,833 participants) in the overview. None of the included systematic reviews reported quantitative data on the efficacy of interventions to manage fatigue or weight loss specific to people with advanced progressive illness. All of the included reviews apart from one were deemed of high methodological quality. For the remaining review we were unable to ascertain the methodological quality of the research strategy as it was described. None of the systematic reviews adequately described whether conflict of interests were present within the included studies.Management of fatigue Amyotrophic lateral sclerosis/motor neuron disease (ALS/MND) - we identified one systematic review (two studies and 52 participants); the intervention was exercise.Cancer - we identified five systematic reviews (116 studies with 17,342 participants); the pharmacological interventions were eicosapentaenoic acid (EPA) and any drug therapy for the management of cancer-related fatigue and the non pharmacological interventions were exercise, interventions by breast care nurses and psychosocial interventions.Chronic obstructive pulmonary disease (COPD) - we identified three systematic reviews (59 studies and 4048 participants); the interventions were self management education programmes, nutritional support and pulmonary rehabilitation.Cystic fibrosis - we identified one systematic review (nine studies and 833 participants); the intervention was physical training.Human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) - we identified two systematic reviews (21 studies and 748 participants); the interventions were progressive resistive exercise and aerobic exercise.Multiple sclerosis (MS) - we identified five systematic reviews (23 studies and 1502 participants); the pharmacological interventions were amantadine and carnitine. The non pharmacological interventions were diet, exercise and occupational therapy.Mixed conditions in advanced stages of illness - we identified one systematic review (five studies and 453 participants); the intervention was medically assisted hydration.Management of weight loss ALS/MND - we identified one systematic review but no studies met the inclusion criteria for the systematic review; the intervention was enteral tube feeding.Cancer - we identified three systematic reviews with a fourth systematic review also containing extractable data on cancer (66 studies and 5601 participants); the pharmacological interventions were megestrol acetate and eicosapentaenoic acid (EPA) (this systematic review is also included in the cancer fatigue section above). The non pharmacological interventions were enteral tube feeding and non invasive interventions for patients with lung cancer.COPD - we identified one systematic review (59 studies and 4048 participants); the intervention was nutritional support. This systematic review is also included in the COPD fatigue section.Cystic fibrosis - we identified two systematic reviews (three studies and 131 participants); the interventions were enteral tube feeding and oral calorie supplements.HIV/AIDS - we identified four systematic reviews (42 studies and 2071 participants); the pharmacological intervention was anabolic steroids. The non pharmacological interventions were nutritional interventions, progressive resistive exercise and aerobic exercise. Both of the systematic reviews on exercise interventions were also included in the HIV/AIDS fatigue section.MS - we found no systematic reviews which considered interventions to manage unintentional weight loss for people with a clinical diagnosis of multiple sclerosis at any stage of illness.Mixed conditions in advanced stages of illness - we identified two systematic reviews (32 studies and 4826 participants); the interventions were megestrol acetate and medically assisted nutrition. AUTHORS' CONCLUSIONS There is a lack of robust evidence for interventions to manage fatigue and/or unintentional weight loss in the advanced stage of progressive illnesses such as advanced cancer, heart failure, lung failure, cystic fibrosis, multiple sclerosis, motor neuron disease, Parkinson's disease, dementia and AIDS. The evidence contained within this overview provides some insight into interventions which may prove of benefit within this population such as exercise, some pharmacological treatments and support for self management.Researchers could improve the methodological quality of future studies by blinding of outcome assessors. Adopting uniform reporting mechanisms for fatigue and weight loss outcome measures would also allow the opportunity for meta-analysis of small studies.Researchers could also improve the applicability of recommendations for interventions to manage fatigue and unintentional weight loss in advanced progressive illness by including subgroup analysis of this population within systematic reviews of applicable interventions.More research is required to ascertain the best interventions to manage fatigue and/or weight loss in advanced illness. There is a need for standardised reporting of these symptoms and agreement amongst researchers of the minimum duration of studies and minimum percentage change in symptom experience that proves the benefits of an intervention. There are, however, challenges in providing meaningful outcome measurements against a background of deteriorating health through disease progression. Interventions to manage these symptoms must also be mindful of the impact on quality of life and should be focused on patient-orientated rather than purely disease-orientated experiences for patients. Systematic reviews and primary intervention studies should include the impact of the interventions on standardised validated quality of life measures.

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
Fatigue is an exceedingly common often treatable problem in cancer patients that profoundly affects all aspects of quality of life. Prevalence estimates have ranged from 50% to 90% of cancer patients overall. After addressing reversible or treatable contributing factors, such as hypothyroidism, anemia, sleep disturbance, pain, emotional distress, climacterium, medication adverse events, metabolic disturbances, or organ dysfunction such as heart failure, myopathy, and pulmonary fibrosis, patients may be screened with a brief fatigue self-assessment tool. All cancer patients should be screened regularly for fatigue. Those with moderate or severe fatigue may benefit from both pharmacologic and nonpharmacologic interventions, while mild fatigue that does not interfere with quality of life can be treated with nonpharmacologic measures alone. Physicians often have insufficient knowledge about fatigue and its treatments or underestimate the impact of fatigue on quality of life, while patients may consider it an unavoidable and untreatable side-effect and fear that reporting it may incite a change toward less aggressive cancer treatment. A practical review may therefore be useful to health care professionals in order to avoid the common barriers to its treatment that exist on the sides of both physicians and patients.

Abstract
SummaryCancer-related fatigue (CRF) is a debilitating symptom that affects the majority of cancer patients. It can occur at all stages of treatment, worsening in advanced disease. It can be especially troublesome in the older person. CRF is often under-recognized and insufficiently treated routinely. This review will discuss both the postulated mechanisms and clinical tools for identifying and monitoring CRF during cancer treatment. The role of drug treatment and exercise to manage CRF is also assessed. Further studies, particularly in older people, are required to improve the poor levels of evidence for current CRF management options.

Abstract
PURPOSE Functional iron deficiency may impair response to erythropoiesis-stimulating agents (ESAs) in iron-replete patients with chemotherapy-associated anemia (CAA). This study evaluated whether coadministration of parenteral iron improves ESA efficacy in patients with CAA. PATIENTS AND METHODS This prospective, multicenter, randomized trial enrolled 502 patients with hemoglobin (Hb) less than 11 g/dL who were undergoing chemotherapy for nonmyeloid malignancies. All patients received darbepoetin alfa once every 3 weeks and were randomly assigned to receive either ferric gluconate 187.5 mg intravenously (IV) every 3 weeks, oral daily ferrous sulfate 325 mg, or oral placebo for 16 weeks. RESULTS There was no difference in the erythropoietic response rate (ie, proportion of patients achieving Hb ≥ 12 g/dL or Hb increase ≥ 2 g/dL from baseline): 69.5% (95% CI, 61.9% to 76.5%) of IV iron-treated patients achieved an erythropoietic response compared with 66.9% (95% CI, 59.1% to 74.0%) who received oral iron and 65.0% (95% CI, 57.2% to 72.3%) who received oral placebo (P = .75). There were also no differences in the proportion of patients requiring red cell transfusions, changes in quality of life, or the dose of darbepoetin administered. Adverse events (AEs) tended to be more common in the IV iron arm: grade 3 or higher AEs occurred in 54% (95% CI, 46% to 61%) of patients receiving IV iron compared with 44% (95% CI, 36% to 52%) who received oral iron and 46% (95% CI, 38% to 54%) who received oral placebo (P = .16). CONCLUSION In patients with CAA, addition of IV ferric gluconate to darbepoetin failed to provide additional benefit compared with oral iron or oral placebo.

Abstract
BACKGROUND Studies have suggested that erythropoietin-stimulating agents (ESAs) may affect progression-free survival (PFS) and overall survival (OS) in a variety of cancer types. Because this finding had not been explored previously in ovarian or primary peritoneal carcinoma, the authors of this report analyzed their ovarian cancer population to determine whether ESA treatment for chemotherapy-induced anemia affected PFS or OS. METHODS A retrospective review was conducted of women who were treated for ovarian cancer at the corresponding author's institution over a 10-year period (from January 1994 to May 2004). Treatment groups were formed based on the use of an ESA. Two analyses of survival were conducted to determine the effect of ESA therapy on PFS and OS. Disease status was modeled as a function of treatment group using a logistic regression model. Kaplan-Meier curves were generated to compare the groups, and a Cox proportional hazards model was fit to the data. RESULTS In total, 343 women were identified. The median age was 57 (interquartile range, 48-68 years). The majority of women were Caucasian (n = 255; 74%) and were diagnosed with stage III (n = 210; 61%), epithelial (n = 268; 78%) ovarian cancer. Although the disease stage at diagnosis and surgical staging significantly affected the rates of disease recurrence and OS, the receipt of an ESA had no effect on PFS (P = .9) or OS (P = .25). CONCLUSIONS The current results indicated that there was no difference in cancer-related PFS or OS with use of ESA in this cohort of women treated for ovarian cancer.

Abstract
AIM Evaluate efficacy and safety of epoetin beta in anaemic patients receiving chemotherapy for a non-myeloid malignancy. PATIENTS AND METHODS This open-label, multicentric, clinical trial was conducted in France among 691 anaemic patients (haemoglobin < or = 12 g/dL) with a solid or haematological malignancy to evaluate the benefit of epoetin beta 30,000 IU/week subcutaneously for 16 weeks. The primary endpoint was the rate of therapeutic response. RESULTS The overall response rate was 60.4% (CI 95%: [56.6%-64.1]). According to initial haemoglobin level < 11 g/dL or between 11 and 12 g/dL, it was 61.2% and 57.5% respectively. Response rates by tumour type (solid and haematological) were similar. The mean haemoglobin level increases were respectively 1.1 g/dL, approximately 2 and 2.2 g/dL at 4, 9, and 12 weeks after treatment initiation. In patients with haemoglobin level < 11 g/dL at inclusion the mean increases in haemoglobin level were respectively 1.17, 2.03 and 2.45 g/dL at 4, 9 and 12 weeks. During study period, 23% of patients required red blood cell transfusion. Overall treatment with epoetin beta was well-tolerated and 7.1% of patients only experienced thromboembolic events. CONCLUSION For treating chemotherapy-induced anaemia in patients with solid or haematological malignancy (especially if haemoglobin level < 11 g/dL), epoetin beta 30.000 IU subcutaneously once-weekly (450 IU/kg/week) is rapidly effective and overall well-tolerated.

Abstract
Cancer patients are well-known to be at increased risk of venous thromboembolism (VTE). However, the risk varies widely between patients and over the natural history of malignancy. Recent data have identified multiple clinical risk factors as well as biomarkers predictive of VTE. Risk factors include patient-associated factors such as age, obesity and medical comorbidities, cancer-associated factors such as site and stage of cancer, and treatment-associated factors, particularly chemotherapy and anti-angiogenic therapy. Biomarkers associated with increased risk of cancer-associated VTE include leukocyte count, platelet count, and levels of tissue factor, P-selectin and D-dimer. This review focuses on the evidence for risk stratification of cancer patients, based on these risk factors and biomarkers, as well as a recently validated predictive model which can be used to identify patients at highest risk. Targeted thromboprophylaxis utilizing model-based and/or biomarker-based approaches may provide an optimal risk-benefit ratio and is currently the focus of ongoing clinical trials.

Abstract
Sepsis is the systemic inflammatory response to infection and can result in multiple organ dysfunction syndrome with associated high mortality, morbidity and health costs. Erythropoietin is a well-established treatment for the anaemia of renal failure due to its anti-apoptotic effects on red blood cells and their precursors. The extra-haemopoietic actions of erythropoietin include vasopressor, anti-apoptotic, cytoprotective and immunomodulating actions, all of which could prove beneficial in sepsis. Attenuation of organ dysfunction has been shown in several animal models and its vasopressor effects have been well characterised in laboratory and clinical settings. Clinical trials of erythropoietin in single organ disorders have suggested promising cytoprotective effects, and while no randomised trials have been performed in patients with sepsis, good quality data exist from studies on anaemia in critically ill patients, giving useful information of its pharmacokinetics and potential for harm. An observational cohort study examining the microvascular effects of erythropoietin is underway and the evidence would support further phase II and III clinical trials examining this molecule as an adjunctive treatment in sepsis.

Abstract
OBJECTIVE To estimate the comparative effectiveness of medical interventions in adults versus children. STUDY DESIGN We identified from the Cochrane Database of Systematic Reviews (Issue 1, 2007) meta-analyses with data on at least 1 adult and 1 pediatric randomized trial with binary primary efficacy outcome. For each meta-analysis, we calculated the summary odds ratio of the adult trials and the pediatric trials, respectively; the relative odds ratio (ROR) of the adult versus pediatric odds ratios per meta-analysis; and the summary ROR across all meta-analyses. ROR <1 means that the experimental intervention is more unfavorable in children than adults. RESULTS Across 128 eligible meta-analyses (1051 adult and 343 pediatric trials), the summary ROR did not show a statistically significant difference between adults and children (0.96; 95% confidence intervals, 0.86 to 1.08). However, in all meta-analyses except for 1, the individual ROR's 95% confidence intervals could not exclude a relative difference in efficacy over 20%. In two-thirds, the relative difference in observed point estimates exceeded 50%. Nine statistically significant discrepancies were identified; 4 of them were also clinically important. CONCLUSIONS Treatment effects are on average similar in adults and children, but available evidence leaves large uncertainty about their relative efficacy. Clinically important discrepancies may occur.

Abstract
BACKGROUND This is an updated version of the original Cochrane review published in issue 1 2008 (Minton 2008). Cancer-related fatigue (CRF) is common, under-recognised and difficult to treat. There have been studies looking at drug interventions to improve CRF but results have been conflicting depending on the population studied and outcome measures used. No previous reviews of this topic have been exhaustive or have synthesised all available data. OBJECTIVES To assess the efficacy of drugs for the management of CRF. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (from Issue 2 2007) MEDLINE and EMBASE from January 2007 to October 2009 and a selection of cancer journals. We searched references of identified articles and contacted authors to obtain unreported data. SELECTION CRITERIA Studies were included in the review if they 1) assessed drug therapy for the management of CRF compared to placebo, usual care or a non-pharmacological intervention in 2) randomised controlled trials (RCT) of 3) adult patients with a clinical diagnosis of cancer. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. Meta-analyses were performed on different drug classes using continuous variable data. MAIN RESULTS Fifty studies met the inclusion criteria. Six additional studies were identified since the original review. Only 31 of these studies involving 7104 participants were judged to have used a sufficiently robust measure of fatigue and thus were deemed suitable for detailed analysis. The drugs were still analysed by class (psychostimulants; haemopoietic growth factors; antidepressants and progestational steroids). Methylphenidate showed a small but significant improvement in fatigue over placebo (Z = 2.83; P = 0.005). Since the publication of the original review increased safety concerns have been raised regarding erythropoietin and this cannot now be recommended in practice.There was a very high degree of statistical and clinical heterogeneity in the trials and the reasons for this are discussed. AUTHORS' CONCLUSIONS There is increasing evidence that psychostimulant trials provide evidence for improvement in CRF at a clinically meaningful level. There is still a requirement for a large scale RCT of methylphenidate to confirm the preliminary results from this review. There is new safety data which indicates that the haemopoietic growth factors are associated with increased adverse outcomes. These drugs can no longer be recommended in the treatment of CRF. Readers of the first review should re-read the document in full.

Abstract
A prospective, open-label, 3-month study was conducted to evaluate the feasibility and short-term clinical effect of subcutaneous erythropoietin injections in patients with anemia and heart failure with preserved ejection fraction (ejection fraction, 55%+/-2%). Using a dose-adjusted algorithm to effect a rate of rise in hemoglobin not to exceed 0.4 g/dL /wk, hemoglobin (10.8+/-0.3 to 12.2+/-0.3 g/dL) and red blood cell volume (1187+/-55 to 1333+/-38 mL) increased with an average weekly dose of 3926 units. Functional measures increased from baseline (6-minute walk test [289+/-24 to 331+/-22 m], exercise time [432+/-62 to 571+/-51 s], and peak oxygen consumption [8.2+/-0.7 to 9.4+/-0.9 mL/kg/min], all P<.05). End-diastolic volume declined significantly (8% volumetric decrease, 108+/-3 to 100+/-3 mL, P =.03), but there were no significant changes in left ventricular mass or estimated left ventricular end-diastolic pressure. Pressure-volume analysis demonstrated a reduction in ventricular capacitance at an end-diastolic pressure of 30 mm Hg without significant changes in contractile state.

Abstract
Although more research needs to be done to determine the optimal role for PCPs during the active phase of cancer treatment, patients, PCPs, and oncologists all see a significant role for primary care in the care of patients with cancer. In the United States, family physicians are actively involved in the care of cancer patients, especially in provision of support, education, and care of intercurrent illness and chronic disease. Fatigue, depression, pain, and psychosocial distress are important symptoms that should be screened for and addressed. The PCP should be aware of adverse effects of chemotherapy and radiation and cancer-related emergencies. Sexual and intimacy concerns, including contraception and fertility, are important to patients entering active cancer treatment but may not be addressed adequately in usual cancer care. Advising the patient in active cancer treatment on issues of general health including common nutritional issues can provide value through the treatment period. Use of CAM is common and several modalities have been shown to benefit patients in the course of cancer treatment.

Abstract
BACKGROUND Chronic heart failure (CHF) is a leading cause of morbidity and mortality worldwide. Anaemia is a common (12-55%) co-morbid condition and is associated with worsening symptoms and increased mortality. Anaemia is treatable and can be targeted in the treatment of patients with CHF. Erythropoiesis-stimulating agents (ESA), supplemented by iron therapy, are used to treat anaemia in chronic kidney disease and cancer, however safety concerns have been raised in these patients. The clinical benefit and safety of these agents in CHF remains unclear. OBJECTIVES To assess the benefits and risks of ESA for CHF patients with anaemia. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library 2008, Issue 3), MEDLINE (1950 to October 2008), EMBASE (1980 to October 2008) and reference lists of articles. No language restrictions were applied. SELECTION CRITERIA Randomised controlled trials of any ESA, with or without iron therapy, in CHF patients were eligible for inclusion. DATA COLLECTION AND ANALYSIS Three reviewers independently assessed study quality and extracted data. Original authors were contacted for additional information. The outcomes of interest were: exercise tolerance, haemoglobin level, New York Heart Association (NYHA) functional class, quality of life, left-ventricular ejection fraction, B-type natriuretic peptide, CHF-related hospitalisations, all-cause mortality and adverse effects. Risk ratios (RR) were calculated for dichotomous data and weighted mean difference (WMD) for continuous data. MAIN RESULTS Eleven studies (794 participants) were included. Overall quality of studies was moderate with nine studies being placebo-controlled but only five double-blinded. Compared to control, ESA treatment significantly improved exercise duration by 96.8 seconds (95% CI 5.2 to 188.4, p=0.04) and 6-minute walk distance by 69.3 metres (95% CI 17.0 to 121.7, p=0.009). Benefit was also noted in terms of peak VO2 (+2.29 mL/kg/min, p=0.007), NYHA class (-0.73, p<0.001), ejection fraction (+5.8%, p<0.001), B-type natriuretic peptide (-226.99 pg/mL, p<0.001) and quality-of-life indicators, with a mean increase in haemoglobin of 1.98 g/dL (p<0.0001). There was also a significantly lower rate of heart failure related hospitalisations (RR 0.62, 95% CI 0.44 to 0.87) and lower all-cause mortality (RR 0.61, 95% CI 0.37 to 0.99). No increase in adverse events with ESA therapy was observed, however studies were of small sample sizes and limited duration. AUTHORS' CONCLUSIONS Meta-analysis of small RCTs suggests that ESA treatment in patients with symptomatic CHF and mild anaemia (haemoglobin more than 10g/dL) can improve anaemia and exercise tolerance, reduce symptoms and have benefits on clinical outcomes. Confirmation requires well-designed studies with careful attention to dose, haemoglobin treatment target and associated iron therapy.

Abstract
Recombinant erythropoietin (EPO) is a growth factor used in the treatment of chemotherapy-induced anemia, but recent studies suggest that EPO may accelerate cancer growth. Although several cancers express EPO receptors (EPORs), the mechanism by which EPOR promotes tumor growth remains poorly understood. Glioblastomas display a cellular hierarchy of self-renewal and tumor propagation restricted to glioma stem cells (GSCs). We find that GSCs express higher levels of EPOR than matched non-stem glioma cells. Prospective enrichment for EPOR on GSCs increased neurosphere formation, suggesting that EPOR can select for a subset of GSCs with increased self-renewal capacity. Targeting EPOR expression with lentiviral mediated short hairpin RNA (shRNA) reduced GSC growth, survival, and neurosphere formation capacity, defining a crucial role for EPOR in GSC maintenance. We further find that STAT3 is an important mediator of EPOR signals in GSCs. EPOR knockdown attenuated the basal activation of STAT3 present in GSCs, and a small molecule inhibitor of STAT3 reduced GSC growth and survival. EPOR signaling was critical for survival in vivo, as targeting EPOR expression decreased GSC tumorigenic potential. Elevated EPOR expression also associated with poor patient outcome. Thus, EPOR on GSCs promotes tumor growth and may explain the poor survival of cancer patients treated with EPO.
