Abstract
OBJECTIVE To investigate the allogeneic blood transfusion (ABT) characteristics of children with acute lymphoblastic leukemia (ALL) in different risk stratification during vincristine, daunorubicin, L-asparaginase and prednisone (VDLP) induction remission. SUBJECTS AND METHODS By referring to electronic medical records, the demographic characteristics, diagnosis, test, and treatment information including ABT were collected. According to the risk stratification of the CCCG-ALL-2015 protocol, ABTs between groups were compared, and the differences were statistically analyzed. RESULTS One hundred sixty-three newly treated children with ALL were enrolled in this study, who received 643.5 U of red blood cells and 377.6 U of platelets (PLTs) during the VDLP. The amount of ABT in the intermediate-risk (IR) group (n=102) was significantly higher than that in the low-risk group (n=61), which were reflected in the red blood cells in the first half of VDLP (P=0.033) and the PLTs in the second half of VDLP (P<0.001). Meanwhile, the PLT counts in the IR group were significantly lower in the same period. The time node was bounded by the minimal residual disease test on the 19th day. CONCLUSIONS Children in the IR group or with unsatisfactory induction may need more ABTs during the VDLP, and the relatively low PLT counts seem to contribute to this. The results of this study can provide a basis for patient blood management, as well as a reference for studying the long-term effects of ABT on children with ALL.

Abstract
Over 400,000 units of blood and blood products are transfused to pediatric patients annually, yet only sparse high-quality data exist to guide the preparation and administration of blood products in this population. The direct application of data from studies in adult patients should be undertaken with caution, as there are dissimilarities in the pathology and physiology between adult and pediatric patients. We provide an overview of available evidence in the field of pediatric transfusion medicine, summarizing indications for blood product transfusion, thresholds for transfusion and indications for blood product modifications.

Abstract
Children with acute lymphoblastic leukemia (ALL) undergo intense anticancer treatment. We systematically reviewed 22 studies evaluating 2,073 ALL patients' health-related quality of life (HRQL) and its clinical/demographic correlates during treatment. Overall HRQL was significantly reduced on treatment. Despite HRQL improvements over time, longitudinal studies reported a proportion of children continued to experience reduced HRQL after treatment completion. We found inconsistent associations between clinical/demographic factors and HRQL outcomes. Tentative evidence emerged for worse HRQL being associated with intensive phases of chemotherapy, corticosteroid therapy, experiencing greater toxicity, older age, and female sex. Longitudinal studies are needed to identify children at-risk of reduced HRQL.

Abstract
The role of erythropoiesis-stimulating agents (ESAs) in the management of chemotherapy-induced anemia (CIA) is becoming increasingly recognized in the field of medical oncology, with paucity of data in pediatrics. We evaluated the efficacy and tolerability of a single-dose darbepoetin alfa, a long-acting ESA, given to 35 pediatric acute lymphoblastic leukemia (ALL) children during induction chemotherapy. Compared to a retrospective control group, the studied patients have required significantly less units of packed red blood cells (0.88 units/patient in the studied group versus 2.04 units in controls), with no major side effects. We recommend further prospective double-blinded studies with more tailored dosing regimens in pediatric ALL cases and solid tumors.

Abstract
Anemia is a common comorbidity of lymphoproliferative malignancies, especially in multiple myeloma. Blood transfusions and ESAs (erythropoiesis stimulating agents) are both possible treatment options, but the latter is often preferred because of the potential risks of unwanted side effects related to blood transfusions. Evidence is accumulating that the use of ESAs in above clinical conditions is safe and effective and not associated with an increase in mortality or serious adverse events. 69.1% of patients achieved a hemoglobin response defined as an increase in hemoglobin of>2g/dl while receiving ESAs and concomitant chemotherapy. If supplemented with iron the hemoglobin response rate can be increased and hence the total dosage and financial cost reduced. A hemoglobin response is often accompanied by an increase in quality of life. HYPO% (hypochromic erythrocytes<5%) is believed to be both a significant positive predictor for the Hb response and also an indicator for iron supplementation if⩾5%. Conventional biochemical markers like serum ferritin concentration and transferrin saturation are not reliable for this use. The effect of EPO stimulating agents as the predictor of the Hb response, quality of life, mortality and the potential adverse events are discussed.

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
Anemia, which is a common problem in cancer patients, has a negative effect on survival by decreasing the efficacy of chemotherapy and particularly of radiotherapy, as well as impairing the quality of life (QoL) of patients. Recombinant human erythropoietin (rHuEPO) decreases a patient's need for transfusions and increases their QoL. The aim of this study was to evaluate the effect of weekly single-dose EPO treatment on transfusion rates, QoL, and hemoglobin (Hb) levels. In addition, patients were followed up for a long period to assess the impact of EPO treatment on survival. The study was conducted from December 2001 to December 2002 in patients with newly diagnosed lymphoma or solid tumors using a prospective and controlled design. EPO-β was given as a single dose of 450 U/kg once a week for 12 weeks. The study and control groups included 16 patients each. Hb levels measured in the study group at the 4th, 8th, and 12th weeks were significantly higher than the values recorded before the start of chemotherapy. In the control group, Hb levels post chemotherapy were significantly lower than values recorded prior to treatment. The increased Hb levels in the study group were significant at the 8th and 12th weeks of treatment compared to levels measured prior to treatment. In the control group, Hb levels at the 4th and 8th weeks were significantly lower than pretreatment levels. When the percent increase of Hb levels of the study and control groups with respect to treatment week was compared, the difference was statistically significant at the 4th, 8th, and 12th weeks. Although the increase on the performance scale within each group during treatment was significant in both the study and control groups, the increase was more marked in the study group. The percent increase on the performance scale with respect to week of treatment was higher in the study group than in the control group. In EPO treatment group, side effects were seen in 38% of patients, with 19% being local pain in the injection area, 13% local hyperemia, and 6% headache. The mean follow-up period of the study and control group was 7.03 ± 0.41 (6.0-7.41) and 7.46 ± 0.45 (6.58-7.83) years, respectively; no statistically significant difference existed between these figures. Overall survival at the end of 7 years of follow-up was 68.8% and 81.3% for the study and control groups, respectively. The use of EPO-β in lymphoma and solid tumor patients on a once-weekly regimen (450 U/kg) was determined to be effective in increasing Hb levels, decreasing transfusion rates, and improving QoL. This regimen was safe, did not cause serious side effects, and can be recommended because of its high patient compliance and tolerability. An effect of EPO on prognosis was not evident. We could not have an explanation on the effect of EPO treatment on prognosis, as there were low number of patients and advanced-staged patients died earlier. Therefore, a larger number of patients are needed to clarify the effect of EPO treatment on prognosis.

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
AIMS To assess the effect of epoetin delta on anaemia in patients with cancer who were receiving chemotherapy. MATERIALS AND METHODS This report includes data from two 12-week studies of epoetin delta: a randomised, double-blind, placebo-controlled study of three times weekly epoetin delta (150 or 300IU/kg) and an open-label extension collecting further efficacy and safety information, in which patients initially received epoetin delta 150IU/kg. Co-primary end points for the double-blind study were an increase in haemoglobin levels and a reduction in the requirement for red blood cell transfusions compared with placebo. RESULTS Double-blind study: 313 cancer patients were randomised to epoetin delta or placebo. Epoetin delta was associated with a significantly greater increase in haemoglobin levels from baseline compared with placebo (epoetin delta 150 and 300IU/kg vs placebo: 2.5 and 2.5g/dl vs 0.6g/dl; P<0.0001 for both comparisons), meeting one co-primary end point. However, there were no significant differences between groups in the proportion of patients requiring red blood cell transfusions (epoetin delta 150 and 300IU/kg vs placebo: 26.0 and 21.9% vs 26.9%), the second co-primary end point. Open-label study: 149 patients entered the extension study. During the extension, haemoglobin levels were maintained and a higher proportion of patients who previously received placebo required transfusions than those who had previously received epoetin delta (previous epoetin delta 150 and 300IU/kg: 7.1 and 11.4% vs previous placebo: 15.9%). Adverse events were as expected for this population in both studies. CONCLUSION Epoetin delta shows potential as a treatment for anaemia in cancer patients receiving chemotherapy.
