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.

PloS one. 2022;17(6):e0270640
Abstract
BACKGROUND Patients with colorectal cancer have a high risk of iron deficiency anaemia (IDA) due to chronic tumour induced blood loss, a reduced dietary iron intake from poor nutrition or gastrointestinal malabsorption. This pilot, double blinded, randomised controlled trial (RCT) examined the effect and feasibility of using preoperative iron isomaltoside for treating iron deficiency anaemia. METHODS Forty eligible adults with IDA were randomised to receive either intravenous iron isomaltoside (20 mg.kg-1 up to 1000 mg over 30 minutes) or usual preoperative care (control) three weeks before scheduled colorectal surgery. The primary outcomes were perioperative changes in haemoglobin and ferritin concentrations. RESULTS The recruitment rate was 78% of all eligible referred patients (1.9 patients/month). The haemoglobin and ferritin concentrations were higher in the iron isomaltoside group than the control group over the perioperative period (group*time interaction P = 0.042 and P < 0.001 respectively). Mean haemoglobin change from baseline to before surgery was higher in the iron isomaltoside group (7.8, 95% CI: 3.2 to 12.3 g.l-1) than the control group (1.7, 95% CI: -1.9 to 5.3 g.l-1) [mean difference 6.1, 95% CI: 0.3 to 11.8 g.l-1; P = 0.040]. The ferritin change from baseline to before surgery between groups was large in favour of the iron isomaltoside group (mean difference 296.9, 95% CI: 200.6 to 393.2 μg.l-1; P < 0.001]. There were no differences between groups in packed red blood cell transfusions needed, surgical complications, quality of recovery and days (alive and) at home within 30 days after surgery. CONCLUSION Iron isomaltoside therapy was safe and had a minimal effect on perioperative changes in haemoglobin concentration. Given the slow recruitment and new evidence emerging during the conduct of this study, conducting a multi-centre RCT based on the current pilot trial protocol is unlikely to be feasible.

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
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
Oral iron promotes intestinal tumourigenesis in animal models. In humans, expression of iron transport proteins are altered in colorectal cancer. This study examined whether the route of iron therapy alters iron transport and tumour growth. Colorectal adenocarcinoma patients with pre-operative iron deficiency anaemia received oral ferrous sulphate (n = 15), or intravenous ferric carboxymaltose (n = 15). Paired (normal and tumour tissues) samples were compared for expression of iron loading, iron transporters, proliferation, apoptosis and Wnt signalling using immunohistochemistry and RT-PCR. Iron loading was increased in tumour and distributed to the stroma in intravenous treatment and to the epithelium in oral treatment. Protein and mRNA expression of proliferation and iron transporters were increased in tumours compared to normal tissues but there were no significant differences between the treatment groups. However, intravenous iron treatment reduced ferritin mRNA levels in tumours and replenished body iron stores. Iron distribution to non-epithelial cells in intravenous iron suggests that iron is less bioavailable to tumour cells. Therefore, intravenous iron may be a better option in the treatment of colorectal cancer patients with iron deficiency anaemia due to its efficiency in replenishing iron levels while its effect on proliferation and iron metabolism is similar to that of oral iron treatment.

Colorectal disease : the official journal of the Association of Coloproctology of Great Britain and Ireland. 2020
Abstract
AIM: Preoperative iron is frequently used for the correction of anaemia in colorectal cancer surgery. However, enteral iron intake may promote tumour growth and progression which could influence cancer recurrence and patient survival. We explore the long term outcomes of patients receiving either oral or intravenous iron replacement therapy as part of a previous randomised controlled trial. METHODS The IVICA trial randomised anaemic colorectal cancer patients to receive either oral (OI, control) or intravenous (IVI, treatment) iron prior to their elective operation. Follow up analysis of all patients recruited to this multicentre trial who underwent surgical resection with curative intent was performed. Kaplan-Meier survival estimates, and Cox proportional hazard models were used to compare groups. A pooled group multivariable analysis comparing patients who achieved resolution of anaemia preoperatively to those who did not was also undertaken. RESULTS 110 of the 116 patients previously enrolled were eligible for analysis (OI n=56, IVI n=54). Median overall follow up duration was 61 months (IQR 46-67). No significant difference in 5-year overall survival (HR 1.22, 95% CI 0.65-2.28 P=0.522) or disease free survival (HR 1.08, 95% CI 0.61-1.92 P=0.79) was observed between OI and IVI. Pooled analysis of treatment groups found that preoperative resolution of anaemia led to improved 5 year overall survival on multivariable analysis (HR 3.38 [1.07-11.56, P=0.044). CONCLUSION We recommend IVI for the preoperative correction of anaemia. Route of iron therapy did not significantly influence survival. Preoperative anaemia correction may lead to an overall survival advantage following elective colorectal cancer surgery.

Journal of thoracic oncology : official publication of the International Association for the Study of Lung Cancer. 2019
Abstract
INTRODUCTION This study evaluated noninferiority of darbepoetin alfa versus placebo for overall survival (OS) and progression-free survival (PFS) in anemic patients with non-small cell lung cancer (NSCLC) treated to a 12.0-g/dL hemoglobin (Hb) ceiling. METHODS Adults with stage IV NSCLC expected to receive ≥2 cycles of myelosuppressive chemotherapy and Hb≤11.0 g/dL were randomized 2:1 to blinded 500 mug darbepoetin alfa or placebo Q3W. The primary endpoint was OS; a stratified Cox proportional hazards model was used to evaluate noninferiority (upper confidence limit for hazard ratio [HR] <1.15). Secondary endpoints were PFS and incidence of transfusions or Hb≤8.0 g/dL from week 5 to end of the efficacy treatment period (EOETP). RESULTS The primary analysis set included 2516 patients: 1680 randomized to darbepoetin alfa; 836 to placebo. The study was stopped early per independent Data Monitoring Committee recommendation after the primary endpoint was met with no new safety concerns. Darbepoetin alfa was noninferior to placebo for OS (stratified HR=0.92; 95%CI, 0.831.01) and PFS (stratified HR=0.95; 95%CI, 0.871.04). Darbepoetin alfa was superior to placebo for transfusion or Hb ≤8.0 g/dL from week 5 to EOETP (stratified OR=0.70; 95%CI, 0.570.86; P<.001). Objective tumor response was similar between the arms (darbepoetin alfa, 36.4%; placebo, 32.6%). Incidence of serious adverse events (AEs) was 31.1% in both arms. No unexpected AEs were observed. CONCLUSIONS Darbepoetin alfa dosed to a 12.0-g/dL Hb ceiling was noninferior to placebo for OS and PFS and significantly reduced odds of transfusion or Hb≤8.0 g/dL in anemic patients with NSCLC receiving myelosuppressive chemotherapy.

Ng O, Keeler B, Simpson JA, Madhusudan S, Brookes M, Acheson A
Nutrition and Cancer. 2018;:1-12.
Abstract
BACKGROUND Anemia is common with esophagogastric adenocarcinoma, increasing mortality, blood transfusions, and reducing quality of life (QOL). No clear evidence exists for safe and effective treatment. METHODS Anemic patients (Hb <12 g/dl women, <13 g/dl men) with esophagogastric adenocarcinoma were recruited before initiation of palliative chemotherapy. Patients were randomized to standard care or single dose of intravenous iron isomaltoside (IVI) before chemotherapy. Post-chemotherapy changes in hemoglobin (Hb), ferritin, transferrin saturations (TSAT), blood transfusions, and QOL were recorded for three cycles of chemotherapy. RESULTS Twenty-seven patients were randomized to standard care (n = 13) or IVI (n = 14). No significant change in Hb was seen (standard care MD -0.6 g/dl 95% CI -0.1-1.1 g/dl, P = 0.336; IVI MD +0.5 g/dl 95% CI -0.1-1.1 g/dl, P = 0.903). An increase in ferritin was seen with IVI after cycle one of chemotherapy (standard care 116 ng/ml; IVI 770 ng/ml, P < 0.05). No difference in blood transfusions was seen between groups (P = 0.851). IVI improved QOL with physical well-being, emotional well-being, anemia-specific QOL, trial outcome index, and total scores all exceeding minimum clinically important difference. No improvement was seen with standard care. CONCLUSIONS This feasibility study suggests IVI improves quality of life and ferritin. Larger adequately powered studies are required to definitively conclude if hemoglobin and blood transfusion changes with IVI.

Keeler BD, Simpson JA, Ng O, Padmanabhan H, Brookes MJ, Acheson AG
The British Journal of Surgery. 2017;104((3):):214-221
Abstract
BACKGROUND Treatment of preoperative anaemia is recommended as part of patient blood management, aiming to minimize perioperative allogeneic red blood cell transfusion. No clear evidence exists outlining which treatment modality should be used in patients with colorectal cancer. The study aimed to compare the efficacy of preoperative intravenous and oral iron in reducing blood transfusion use in anaemic patients undergoing elective colorectal cancer surgery. METHODS Anaemic patients with non-metastatic colorectal adenocarcinoma were recruited at least 2 weeks before surgery and randomized to receive oral (ferrous sulphate) or intravenous (ferric carboxymaltose) iron. Perioperative changes in haemoglobin, ferritin, transferrin saturation and blood transfusion use were recorded until postoperative outpatient review. RESULTS Some 116 patients were included in the study. There was no difference in blood transfusion use from recruitment to trial completion in terms of either volume of blood administered (P = 0.841) or number of patients transfused (P = 0.470). Despite this, increases in haemoglobin after treatment were higher with intravenous iron (median 1.55 (i.q.r. 0.93-2.58) versus 0.50 (-0.13 to 1.33) g/dl; P < 0.001), which was associated with fewer anaemic patients at the time of surgery (75 versus 90 per cent; P = 0.048). Haemoglobin levels were thus higher at surgery after treatment with intravenous than with oral iron (mean 11.9 (95 per cent c.i. 11.5 to 12.3) versus 11.0 (10.6 to 11.4) g/dl respectively; P = 0.002), as were ferritin (P < 0.001) and transferrin saturation (P < 0.001) levels. CONCLUSION Intravenous iron did not reduce the blood transfusion requirement but was more effective than oral iron at treating preoperative anaemia and iron deficiency in patients undergoing colorectal cancer surgery.
