Abstract
BACKGROUND Transfusion of granulocytes obtained by apheresis is beneficial in febrile neutropenia (FN) but expensive and time-consuming. Buffy-coat-derived granulocytes could be an alternative. We studied the efficacy and safety of the administration of irradiated buffy-coat-derived granulocytes along with the standard of care in pediatric high-risk (HR) FN. METHODS Sixty children ≤18 years with malignancy and chemotherapy-induced HR FN were randomized to either the granulocyte transfusion (GT) arm which received irradiated buffy-coat derived granulocyte transfusion along with the standard treatment or the standard treatment (ST) arm. RESULTS Baseline characteristics, day-to-defervescence, antibiotic duration, hospital stay, and mortality were comparable between the groups. A significant difference was seen in days to achieve absolute neutrophil count (ANC) >500/mm(3) in the 2 groups: 4.5 days (3-6.5) in the GT arm v/s 8 days (4-11) in the ST arm (P=0.01). CONCLUSION Buffy-coat-derived granulocyte transfusion was safe and led to early hematological recovery but was not associated with survival benefits. Future studies with earlier initiation in the intended dose could be undertaken to generate more evidence.
PICO Summary
Population
Children with malignancy and chemotherapy-induced high-risk febrile neutropenia (n= 60).
Intervention
Irradiated buffy-coat derived granulocyte transfusion along with the standard treatment (GT arm, n= 30).
Comparison
Standard treatment, including: antimicrobials, blood component support, and G-CSF as per the protocol (ST arm, n= 30).
Outcome
Baseline characteristics, day-to-defervescence, antibiotic duration, hospital stay, and mortality were comparable between the groups. A significant difference was seen in days to achieve absolute neutrophil count >500/mm(3) in the 2 groups: 4.5 days (3, 6.5) in the GT arm versus 8 days (4, 11) in the ST arm.

Abstract
BACKGROUND Anaemia is highly prevalent in people with advanced, palliative cancer yet sufficiently effective and safe treatments are lacking. Oral iron is poorly tolerated, and blood transfusion offers only transient benefits. Intravenous iron has shown promise as an effective treatment for anaemia but its use for people with advanced, palliative cancer lacks evidence. AIMS To assess feasibility of the trial design according to screening, recruitment, and attrition rates. To evaluate the efficacy of intravenous iron to treat anaemia in people with solid tumours, receiving palliative care. DESIGN A multicentre, randomised, double blind, placebo-controlled trial of intravenous iron (ferric derisomaltose, Monofer(®)). Outcomes included trial feasibility, change in blood indices, and change in quality of life via three validated questionnaires (EQ5D5L, QLQC30, and the FACIT-F) over 8 weeks. (ISRCTN; 13370767). SETTING/PARTICIPANTS People with anaemia and advanced solid tumours who were fatigued with a performance status ⩽2 receiving support from a specialist palliative care service. RESULTS 34 participants were randomised over 16 months (17 iron, 17 placebo). Among those eligible 47% of people agreed to participate and total study attrition was 26%. Blinding was successful in all participants. There were no serious adverse reactions. Results indicated that intravenous iron may be efficacious at improving participant haemoglobin, iron stores and select fatigue specific quality of life measures compared to placebo. CONCLUSION The trial was feasible according to recruitment and attrition rates. Intravenous iron increased haemoglobin and may improve fatigue specific quality of life measures compared to placebo. A definitive trial is required for confirmation.
PICO Summary
Population
People with anaemia and advanced solid tumours, enrolled in the Intravenous Iron for Cancer Related Anaemia Symptoms (ICaRAS) trial (n= 34).
Intervention
Intravenous iron (n= 17).
Comparison
Placebo: sodium chloride (n= 17).
Outcome
Outcomes included trial feasibility, change in blood indices, and change in quality of life via three validated questionnaires over 8 weeks. Among those eligible, 47% of people agreed to participate and total study attrition was 26%. Blinding was successful in all participants. There were no serious adverse reactions. Compared to baseline, there was a significant rise in haemoglobin, ferritin, and transferrin saturation % at weeks 4 and 8 for participants in the iron group but not the placebo group. Anaemia resolution was achieved in 39% of intravenous iron participants by week 8 compared to 8% of the placebo group.

Abstract
INTRODUCTION Packed red blood cell (RBC) transfusion is frequently used in patients undergoing radiotherapy (RT) because retrospective data suggest that anemic patients may respond sub-optimally to RT. No high-quality evidence currently exists to guide transfusion practices and establish hemoglobin (Hb) transfusion thresholds for this patient population, and practice varies significantly across centers. This systematic review investigated whether maintaining higher Hb via transfusion in radiation oncology patients leads to improved outcomes. METHODS We performed a literature search of studies comparing RBC transfusion thresholds in radiation oncology patients. Included studies assessed patients receiving RT for malignancy of any diagnosis or stage. Excluded studies did not evaluate Hb or transfusion as an intervention or outcome. The primary outcome was overall survival. Secondary outcomes included locoregional control, number of transfusions and adverse events. RESULTS One study met inclusion criteria. The study pooled results from two randomized controlled trials that stratified anemic patients with head and neck squamous cell carcinoma to RBC transfusion versus no transfusion. The study found no significant differences in overall survival or locoregional control after five years, despite increased Hb levels in the transfused group. We conducted a narrative review by extracting data from 10 non-comparative studies involving transfusion in patients receiving RT. Results demonstrated no consistent conclusions regarding whether transfusions improve or worsen outcomes. CONCLUSIONS There is a lack of data on the effects of RBC transfusion on outcomes in patients undergoing RT. Well-designed prospective studies are needed in this area.
PICO Summary
Population
Patients undergoing radiotherapy (11 studies).
Intervention
Red blood cell transfusion.
Comparison
No transfusion.
Outcome
Only one study met the inclusion criteria which pooled results from two randomized controlled trials (DAHANCA 5 and 7). The study found no significant differences in overall survival or locoregional control after five years, despite increased haemoglobin levels in the transfused group (n= 235) vs. no transfused group (n= 230). A narrative review was conducted by extracting data from 10 other non-comparative studies involving transfusion in patients receiving radiotherapy. There were no consistent conclusions from these 10 studies on whether transfusions improve or worsen outcomes.

Abstract
PURPOSE Erythropoiesis-stimulating agents (ESA) are effective for chemotherapy-induced anemia (CIA) but associated with serious adverse events. Safer alternatives would be beneficial in this population. The efficacy and safety of ferric carboxymaltose (FCM) as monotherapy for CIA was evaluated. METHODS This Phase 3, 18-week, double-blind, placebo-controlled study randomized adults with ≥4 weeks of chemotherapy remaining for treatment of nonmyeloid malignancies with CIA to FCM (two 15 mg/kg infusions 7 days apart; maximum dose, 750 mg single/1500 mg total) or placebo. The primary efficacy endpoint was percentage of patients with decreases in hemoglobin (Hb) ≥0.5 g/dL from weeks 3 to 18; the key secondary efficacy endpoint was change in Hb from baseline to week 18. Inclusion criteria included: (Hb) 8-11 g/dL, ferritin 100-800 ng/mL, and transferrin saturation (TSAT) ≤35%. RESULTS In 244 patients (n=122, both groups), the percent who maintained Hb within 0.5 g/dL of baseline from weeks 3 to 18 was significantly higher with FCM versus placebo (50.8% vs 35.3%; P=0.01). Mean change in Hb from baseline to week 18 was similar between FCM and placebo (1.04 vs 0.87 g/dL) but significantly greater with FCM with baseline Hb ≤9.9 g/dL (1.08 vs 0.42 g/dL; P=0.01). The percent with ≥1 g/dL increase from baseline was significantly higher with FCM versus placebo (71% vs 54%; P=0.01), occurring in a median 43 versus 85 days (P=0.001). Common adverse events in the FCM arm included neutropenia (17%), hypophosphatemia (16%), and fatigue (15%). CONCLUSION FCM monotherapy effectively maintained Hb and was well tolerated in CIA.

Abstract
BACKGROUND Transfusion strategies are involving the survival and prognosis of patients with malignant neoplasm and the rational utilization of medical resources, but there are still controversy between different transfusion strategies. The aim of this article is to compare the benefit and harm of restrictive and liberal red blood cell (RBC) transfusion strategies in patients with malignant tumors. METHODS We searched articles in the databases of PubMed, Cochrane Library, Web of Science, Embase and major conference proceedings, identified all randomized controlled trials (RCTs) and compared restrictive transfusion strategies with those that are liberal until MARCH 18, 2019. We used risk ratio (RR) and and 95 % confidence interval (95 %CI) to calculate the results of dichotomous variables, and the study heterogeneity was assessed by using the I(2) statistics. Also, we did sensitivity analysis and quality assessment. RESULTS Restrictive transfusion policies appear to have no effect on all-cause mortality (RR 1.33; 95 % CI 0.74-2.38; P = 0.34), compared with liberal policies. 2 trials including 498 patients were included of renal replacement therapy (RR 1.38; 95 % CI, 0.73-2.59; P = 0.32; I(2) = 0%). Myocardial infarction (RR 1.17; 95 % CI, 0.33-4.1; P = 0.81; I(2) = 0%) and ICU readmission were also mentioned in these articles (RR 1.19; 95 % CI, 0.7-2.04; P = 0.52; I(2) = 0%). However, the RR of hospital length can't be evaluated. CONCLUSION Restrictive transfusion strategies were not associated with all-cause mortality and other clinical outcomes in malignant tumors, and may be more suitable for patients' quality of life and medical economy than liberal.
PICO Summary
Population
Patients with malignant tumours (3 randomised controlled trials (RCTs) n= 587).
Intervention
Restrictive red blood cell transfusion strategy (n= 311).
Comparison
Liberal red blood cell transfusion strategy (n= 276).
Outcome
Restrictive transfusion strategies were not associated with all-cause mortality and other clinical outcomes in malignant tumours. Secondary outcomes reported included incidence of renal replacement therapy (2 RCTs, n=498; RR 1.38), myocardial infarction (RR 1.17) and intensive care unit readmission (RR 1.19).

Abstract
PURPOSE To update the American Society of Clinical Oncology (ASCO)/American Society of Hematology (ASH) recommendations for use of erythropoiesis-stimulating agents (ESAs) in patients with cancer. METHODS PubMed and the Cochrane Library were searched for randomized controlled trials (RCTs) and meta-analyses of RCTs in patients with cancer published from January 31, 2010, through May 14, 2018. For biosimilar ESAs, the literature search was expanded to include meta-analyses and RCTs in patients with cancer or chronic kidney disease and cohort studies in patients with cancer due to limited RCT evidence in the cancer setting. ASCO and ASH convened an Expert Panel to review the evidence and revise previous recommendations as needed. RESULTS The primary literature review included 15 meta-analyses of RCTs and two RCTs. A growing body of evidence suggests that adding iron to treatment with an ESA may improve hematopoietic response and reduce the likelihood of RBC transfusion. The biosimilar literature review suggested that biosimilars of epoetin alfa have similar efficacy and safety to reference products, although evidence in cancer remains limited. RECOMMENDATIONS ESAs (including biosimilars) may be offered to patients with chemotherapy-associated anemia whose cancer treatment is not curative in intent and whose hemoglobin has declined to < 10 g/dL. RBC transfusion is also an option. With the exception of selected patients with myelodysplastic syndromes, ESAs should not be offered to most patients with nonchemotherapy-associated anemia. During ESA treatment, hemoglobin may be increased to the lowest concentration needed to avoid transfusions. Iron replacement may be used to improve hemoglobin response and reduce RBC transfusions for patients receiving ESA with or without iron deficiency. Additional information is available at www.asco.org/supportive-care-guidelines and www.hematology.org/guidelines.
PICO Summary
Population
Patients with cancer or chronic kidney disease (17 studies).
Intervention
Erythropoiesis-stimulating agents (ESAs) including biosimilars.
Comparison
Addition of iron to an ESA, placebo or best standard therapy.
Outcome
A growing body of evidence suggested that adding iron to treatment with an ESA may improve hematopoietic response and reduce the likelihood of red blood cell transfusion. The biosimilar literature review suggested that biosimilars of epoetin alfa have similar efficacy and safety to reference products, although evidence in cancer remained limited.
