ferric-oxide--saccharated and Colorectal-Neoplasms

Recent clinical guidelines suggest that treatment of postoperative anaemia in colorectal cancer surgery with intravenous iron reduces transfusion requirements and improves outcomes. The study aimed at comparing two intravenous iron regimens in anaemic patients after colorectal cancer surgery.. This was a single-centre, open-label, randomised, controlled trial in patients undergoing elective colorectal cancer surgery. Patients with moderate to severe anaemia (haemoglobin [Hb] <11 g/dL) after surgery were randomly assigned 1:1 to receive ferric carboxymaltose (FC; 1,000 mg, single dose) or iron sucrose (IS; 200 mg every 48 hours until covering the total iron deficit or discharge). Randomisation was stratified by Hb level: <10 g/dL (Group A) or ≥10-10.9 (Group B). The primary endpoint was the change in Hb concentration at postoperative day 30. Secondary endpoints included iron status parameters, transfusion requirements, complications, and length of hospital stay.. From September 2015 to May 2018, 104 patients were randomised (FC 50, IS 54). The median intravenous iron dose was 1,000 mg and 600 mg in the FC and IS groups, respectively. There were no between-group differences in mean change in Hb from postoperative day 1 to postoperative day 30 (FC: 2.5 g/dL, 95% CI: 2.1-2.9; IS: 2.4 g/dL, 95% CI: 2.0-2.8; p=0.52), in transfusion requirements or length of stay. The infection rate was lower in the FC group compared with the IS group (9.8% vs 37.2%, respectively).. The administration of approximately 500 mg of IS resulted in an increase in Hb at postoperative day 30 similar to that of 1,000 mg of FC, but it was associated with a higher infection rate. Future research will be needed to confirm the results, and to choose the best regime in terms of effectiveness and side effects to treat postoperative anaemia in colorectal cancer patients.

Patients with colorectal cancer (CRC) often present with associated anaemia which is usually present at the time of diagnosis and is aggravated during the postoperative period due to blood loss during the surgery process. Several guidelines advocate for the treatment of postoperative anaemia in these patients in order to prevent complications and allogeneic blood transfusions. However, there are no publications to shed light on the effectiveness of intravenous iron (IVI) administration after CRC surgery and the optimal dose and regimen. We have started a clinical trial with the objective of comparing the effectiveness of 1000 mg of ferric carboxymaltose with fractionated iron sucrose 200 g/48 h for the treatment of postoperative anaemia, by measuring the change of haemoglobin (Hb) levels from postoperative day (POD) 1 to POD 30.. We designed an open label randomised controlled trial to compare two postoperative IVI treatment regimens. Patients aged > 18 years undergoing CRC surgery, with Hb < 11 g/dL on POD 1 are randomly assigned to receive either 1000 mg of ferric carboxymaltose (single dose) or 200 g/48 h of iron sucrose. The main study endpoint will be the change from POD 1 to POD 30 in Hb levels and the key secondary endpoint the percentage of patients with Hb levels ≥ 13 g/dL at POD 30. Other secondary endpoints include: changes in iron metabolism parameters (Fe, ferritin, transferrin, % saturated trasferrin) at POD 30; total doses of iron received; number of postoperative transfusions; compliance with oral iron treatment; number of medical and surgical complications; adverse reactions reported by the patient; use of health resources after surgery; and changes in quality of life (QoL). It has been estimated that a sample of 48 patients per group will allow detecting a difference of 0.75 g/dL in Hb in the change in Hb levels from POD 1 to POD 30.. The results of this study will confirm if the single dose of 1000 mg ferric carboxymaltose should be preferred in front of the fractionated doses and in which type of patients this regimen should be used preferably..

The transfusion rate following colorectal cancer resection is between 10 and 30 per cent. Receipt of allogeneic blood is not without risk or cost. A preoperative adjunct that reduced the need for transfusion would mitigate these risks. This study was designed to determine whether iron sucrose reduces the likelihood of postoperative blood transfusion in patients undergoing elective colorectal cancer resection.. In this randomized prospective blinded placebo-controlled trial of patients undergoing resectional surgery with a preoperative diagnosis of colorectal cancer, 600 mg iron sucrose or placebo was given intravenously in two divided doses, at least 24 h apart, 14 days before surgery. The primary outcome measures were serum haemoglobin concentration, recorded at recruitment, immediately before surgery and at discharge, and perioperative blood transfusions.. No difference was demonstrated between treatment groups (iron sucrose, 34 patients; placebo, 26) for any of the primary outcome measures, for either the whole study population or a subgroup of anaemic patients.. This pilot study provided no support for the use of intravenous iron sucrose as a preoperative adjunct to increase preoperative haemoglobin levels and thereby reduce the likelihood of allogeneic blood transfusion for patients undergoing resectional surgery for colorectal cancer.. 2005-003608-13UK (Medicines and Healthcare products Regulatory Agency).
