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 A third of patients with colorectal cancer who are eligible for surgery in high-income countries have concomitant anaemia associated with adverse outcomes. We aimed to compare the efficacy of preoperative intravenous and oral iron supplementation in patients with colorectal cancer and iron deficiency anaemia. METHODS In the FIT multicentre, open-label, randomised, controlled trial, adult patients (aged 18 years or older) with M0 stage colorectal cancer scheduled for elective curative resection and iron deficiency anaemia (defined as haemoglobin level of less than 7·5 mmol/L (12 g/dL) for women and less than 8 mmol/L (13 g/dL) for men, and a transferrin saturation of less than 20%) were randomly assigned to either 1-2 g of ferric carboxymaltose intravenously or three tablets of 200 mg of oral ferrous fumarate daily. The primary endpoint was the proportion of patients with normalised haemoglobin levels before surgery (≥12 g/dL for women and ≥13 g/dL for men). An intention-to-treat analysis was done for the primary analysis. Safety was analysed in all patients who received treatment. The trial was registered at ClincalTrials.gov, NCT02243735, and has completed recruitment. FINDINGS Between Oct 31, 2014, and Feb 23, 2021, 202 patients were included and assigned to intravenous (n=96) or oral (n=106) iron treatment. Treatment began a median of 14 days (IQR 11-22) before surgery for intravenous iron and 19 days (IQR 13-27) for oral iron. Normalisation of haemoglobin at day of admission was reached in 14 (17%) of 84 patients treated intravenously and 15 (16%) of 97 patients treated orally (relative risk [RR] 1·08 [95% CI 0·55-2·10]; p=0·83), but the proportion of patients with normalised haemoglobin significantly increased for the intravenous treatment group at later timepoints (49 [60%] of 82 vs 18 [21%] of 88 at 30 days; RR 2·92 [95% CI 1·87-4·58]; p<0·0001). The most prevalent treatment-related adverse event was discoloured faeces (grade 1) after oral iron treatment (14 [13%] of 105), and no treatment-related serious adverse events or deaths were observed in either group. No differences in other safety outcomes were seen, and the most common serious adverse events were anastomotic leakage (11 [5%] of 202), aspiration pneumonia (5 [2%] of 202), and intra-abdominal abscess (5 [2%] 202). INTERPRETATION Normalisation of haemoglobin before surgery was infrequent with both treatment regimens, but significantly improved at all other timepoints following intravenous iron treatment. Restoration of iron stores was feasible only with intravenous iron. In selected patients, surgery might be delayed to augment the effect of intravenous iron on haemoglobin normalisation.

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
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 AND OBJECTIVES Allogeneic blood transfusions are associated with worse postoperative outcomes in oncologic surgery. The aim of this study was to introduce a preoperative intervention to reduce transfusion rates in this population. METHODS Adult patients undergoing major oncologic surgery in five categories with similar transfusion rates were recruited. Enrollees received a single preoperative intravenous dose of placebo or tranexamic acid (1000 mg). The primary outcome measure was perioperative transfusion rate. Secondary outcome measures included: estimated blood loss, thromboembolic events, morbidity, hospital length of stay, and readmission rate. RESULTS Seventy-six patients were enrolled, 39 in the tranexamic acid group and 37 in the placebo group, respectively. Demographics and surgery type were equivalent between groups. The transfusion rates were 8 out of 39 (20.5%) in the tranexamic acid group and 5 out of 37 (13.5%) in the placebo group, respectively (P = .418). Median estimated blood loss was 400 mL (interquartile range [IQR] = 150-600) in the tranexamic acid group compared with 300 mL (IQR = 150-800) in the placebo group (P = .983). There was one pulmonary embolism in each arm and no deep venous thrombosis (P > .999). CONCLUSION Preoperative administration of tranexamic acid at a 1000 mg intravenous dose does not decrease transfusion rates or estimated blood loss in patients undergoing major oncologic surgery.
