20 Patients will be recruited with confirmed colorectal adenocarcinoma and anemia who are planned to undergo surgery. All patients will be treated with a single dose of 1g intravenous ferric carboxymaltose (FERINJECT).
It is hypothesized that intravenous iron supplementation is efficacious at raising haemoglobin levels and reduced blood transfusion requirements.
Condition or disease | Intervention/treatment | Phase |
---|---|---|
Colorectal Neoplasm Anemia | Drug: Intravenous ferric carboxymaltose | Phase 4 |
Patients who are anemic at the time of operation have been shown to have an increased frequency of complications including wound infection and longer post-operative admissions. Similarly, patients who are anemic at the time of their cancer operation are more likely to require a blood transfusion which may increase the risk of recurrence of the cancer.
At present, oral iron is often used to treat anemia preoperatively in an attempt to minimize the risk above. This drug is often poorly tolerated due to the side effect profile. Blood transfusions can also be administered but expose the patient to other risks including infection and transfusion associated reactions. In order to overcome these issues, intravenous iron preparations have been developed and have improved in safety.
This is open label clinical trial, which looks to investigate the efficacy of intravenous iron is in the treatment of preoperative anemia in colorectal patients. The outcomes reviewed will include the amount and frequency of blood transfusions received, changes in patient blood profiles operative complications and hospital length of stay. The role of hepcidin as a biomarker of treatment response will also be assessed.
All data will be confidentially recorded on a Case Report Form, as will drug reactions and side effects.

- Number of patients transfused allogenic red blood cells [ Time Frame: Patients will be followed from recruitment to the study until postoperative discharge from hospital, which will be an expected average of 4 weeks ]To determine if the administration of intravenous iron reduces the number of expected allogenic red blood cell transfusions from recruitment to the perioperative phase
- Hemoglobin levels [ Time Frame: Patients will be followed from recruitment to the study until 8 weeks post operatively, which will be an expected average of 10 weeks ]To determine if intravenous iron significantly increases hemoglobin levels in the preoperative optimization of patients
- Hepcidin levels [ Time Frame: Patients will be followed from recruitment to the study until the day after surgery, which will be an expected average of 3 weeks ]To monitor changes in hepcidin in response to treatment and review if this can predict response to intravenous iron therapy
- Erythropoietin levels [ Time Frame: Patients will be followed from recruitment to the study until 8 weeks post operatively, which will be an expected average of 10 weeks ]To monitor changes in Erythropoietin in response to treatment and review if this can predict response to intravenous iron therapy
- Transferrin saturation levels [ Time Frame: Patients will be followed from recruitment to the study until 8 weeks post operatively, which will be an expected average of 10 weeks ]To monitor changes in transferrin saturation levels in response to treatment and review if this can predict response to intravenous iron therapy
- Ferritin levels [ Time Frame: Patients will be followed from recruitment to the study until 8 weeks post operatively, which will be an expected average of 10 weeks ]To monitor changes in ferritin levels in response to treatment and review if this can predict response to intravenous iron therapy
- C Reactive Protein levels [ Time Frame: Patients will be followed from recruitment to the study until 8 weeks post operatively, which will be an expected average of 10 weeks ]To monitor changes in C Reactive Protein levels over the course of the study, and review if this can predict response to intravenous iron therapy, or is associated with changes in hepcidin
- Number of adverse events associated with intravenous iron infusion [ Time Frame: Patients will be followed from recruitment to the study until postoperative discharge from hospital, which will be an expected average of 4 weeks ]To assess the safety and feasibility of the principle of administration of intravenous iron in a single dose, preoperative outpatient visit
