Intravenous iron in oncology.
Intravenous iron (IV Fe) as an adjunct to therapy with erythropoiesis- stimulatory agents (ESAs) is standard care in dialysis-associated anemia, adding huge increments in hemoglobin and hematopoietic responses and decreased transfusions without significant toxicity. Cost savings, decreased exposure to ESAs, and decreased times to reach target hemoglobins are realized. Although similar benefits have been seen in all studies performed in patients with chemotherapy-induced anemia (CIA), experts are reluctant to incorporate routine use of IV Fe into treatment, largely because of misinterpretation and misunderstanding of the clinical nature of adverse events reportedly associated with its administration. IV Fe is therefore underused in oncology patients with anemia. Published experience with more than 1000 patients in clinical trials involving the use of IV Fe suggests minimal toxicity and substantial benefit are experienced when high molecular weight iron dextran is avoided. This article presents evidence recommending routine incorporation of IV Fe into treatment for CIA.

The role of intravenous iron in cancer-related anemia.
Patients with cancer may have an absolute or functional iron deficiency as a result of their disease or its treatment. These conditions can lead to an insufficient supply of iron for incorporation into erythrocytes during supportive care with erythropoiesis-stimulating proteins for chemotherapy. The use of supplemental iron therapy is well established in patients with chronic kidney disease and anemia, but less well studied in the oncology/hematology setting. Furthermore, the use of oral iron formulations in patients with cancer and anemia is limited by poor absorption in the duodenum, arduous dosing requirements (three times a day), and a high likelihood of gastrointestinal side effects. Two recent studies have shown that intravenous (i.v.) iron (iron dextran or ferric gluconate) increases the hematopoietic response rates in cancer patients who were receiving chemotherapy and treated with epoetin alfa (Procrit) for anemia. The effects on hemoglobin levels and measures of iron metabolism were notably greater with i.v. iron formulations than with oral iron formulations. The results from several ongoing trials of i.v. iron in patients treated with epoetin alfa or darbepoetin alfa (Aranesp) for chemotherapy-induced anemia should lead to a greater understanding of the role of i.v. iron supplementation in improving the hematopoietic responses in these patients.

Phase III, randomized study of the effects of parenteral iron, oral iron, or no iron supplementation on the erythropoietic response to darbepoetin alfa for patients with chemotherapy-associated anemia.
Functional iron deficiency may impair response to erythropoiesis-stimulating agents (ESAs) in iron-replete patients with chemotherapy-associated anemia (CAA). This study evaluated whether coadministration of parenteral iron improves ESA efficacy in patients with CAA.. This prospective, multicenter, randomized trial enrolled 502 patients with hemoglobin (Hb) less than 11 g/dL who were undergoing chemotherapy for nonmyeloid malignancies. All patients received darbepoetin alfa once every 3 weeks and were randomly assigned to receive either ferric gluconate 187.5 mg intravenously (IV) every 3 weeks, oral daily ferrous sulfate 325 mg, or oral placebo for 16 weeks.. There was no difference in the erythropoietic response rate (ie, proportion of patients achieving Hb ≥ 12 g/dL or Hb increase ≥ 2 g/dL from baseline): 69.5% (95% CI, 61.9% to 76.5%) of IV iron-treated patients achieved an erythropoietic response compared with 66.9% (95% CI, 59.1% to 74.0%) who received oral iron and 65.0% (95% CI, 57.2% to 72.3%) who received oral placebo (P = .75). There were also no differences in the proportion of patients requiring red cell transfusions, changes in quality of life, or the dose of darbepoetin administered. Adverse events (AEs) tended to be more common in the IV iron arm: grade 3 or higher AEs occurred in 54% (95% CI, 46% to 61%) of patients receiving IV iron compared with 44% (95% CI, 36% to 52%) who received oral iron and 46% (95% CI, 38% to 54%) who received oral placebo (P = .16).. In patients with CAA, addition of IV ferric gluconate to darbepoetin failed to provide additional benefit compared with oral iron or oral placebo.

Efficacy and safety of oral lactoferrin supplementation in combination with rHuEPO-beta for the treatment of anemia in advanced cancer patients undergoing chemotherapy: open-label, randomized controlled study.
Advanced-stage cancer patients often suffer from anemia that closely resembles the anemia of chronic inflammatory diseases characterized by specific changes in iron homeostasis and absorption. i.v. iron improves the efficacy of recombinant human erythropoietin (rHuEPO) in anemic cancer patients undergoing chemotherapy. We report the results of an open-label, randomized, prospective trial aimed at testing the efficacy and safety of treatment with oral lactoferrin versus i.v. iron, both combined with rHuEPO, for the treatment of anemia in a population of 148 advanced cancer patients undergoing chemotherapy. All patients received s.c. rHuEPO-beta, 30,000 UI once weekly for 12 weeks, and were randomly assigned to ferric gluconate (125 mg i.v. weekly) or lactoferrin (200 mg/day). Both arms showed a significant hemoglobin increase. No difference in the mean hemoglobin increase or the hematopoietic response, time to hematopoietic response, or mean change in serum iron, C-reactive protein, or erythrocyte sedimentation rate were observed between arms. In contrast, ferritin decreased in the lactoferrin arm whereas it increased in the i.v. iron arm. In conclusion, these results show similar efficacy for oral lactoferrin and for i.v. iron, combined with rHuEPO, for the treatment of anemia in advanced cancer patients undergoing chemotherapy.

Intravenous ferric gluconate significantly improves response to epoetin alfa versus oral iron or no iron in anemic patients with cancer receiving chemotherapy.
To evaluate the safety and efficacy of intravenous (IV) sodium ferric gluconate complex (FG), oral ferrous sulfate, or no iron to increase hemoglobin (Hb) in anemic cancer patients receiving chemotherapy and epoetin alfa.. In this open-label, multicenter trial, 187 patients with chemotherapy-related anemia (Hb <11 g/dl; serum ferritin > or =100 ng/ml or transferrin saturation > or =15%) scheduled to receive chemotherapy and epoetin alfa (40,000 U subcutaneously weekly) were randomized to 8 weeks of 125 mg of IV FG weekly, 325 mg of oral ferrous sulfate three times daily, or no iron. The primary outcome was a change in Hb from baseline to endpoint, first whole-blood or red blood cell transfusion, or study withdrawal.. One hundred twenty-nine patients were evaluable for efficacy (FG, n = 41; oral iron, n = 44; no iron, n = 44). Mean increase in Hb was 2.4 g/dl (95% confidence interval [CI], 2.1-2.7) for FG (p = .0092 vs. oral iron; p = .0044 vs. no iron), 1.6 g/dl (95% CI, 1.1-2.1) for oral iron (p =.7695 vs. no iron), and 1.5 g/dl (95% CI, 1.1-1.9) for no iron. Hb response (increase > or =2 g/dl) was 73% for FG (p = .0099 vs. oral iron; p = .0029 vs. no iron), 46% for oral iron (p = .6687 vs. no iron), and 41% for no iron. FG was well tolerated.. For cancer patients with chemotherapy-related anemia receiving epoetin alfa, FG produces a significantly greater increase in Hb and Hb response compared with oral iron or no iron, supporting more aggressive treatment with IV iron supplementation for these patients.

Thrombocytosis and venous thromboembolism in cancer patients with chemotherapy induced anemia may be related to ESA induced iron restricted erythropoiesis and reversed by administration of IV iron.
ESA therapy can increase hemoglobin, decrease blood transfusions, and improve quality of life in patients with chemotherapy induced anemia (CIA). Despite its benefits, ESA therapy increases the risk of venous thromboembolism (VTE) in cancer patients by 50% and can also cause iron restricted erythropoiesis in CIA patients, which may augment the tendency to develop VTE. We postulated that thrombocytosis, a risk factor for VTE in cancer patients, in CIA patients on ESA therapy might be a result of ESA induced iron restricted erythropoiesis. We performed a retrospective analysis of 187 CIA patients who were randomized to receive weekly Epoetin and IV ferric gluconate, oral ferrous sulfate, or no iron for 8 weeks. Nineteen patients experienced 29 VTEs, and patients, whose platelets increased to ≥350,000 cells/uL were three times more likely to experience a VTE (OR 2.9, P = 0.036, logistic regression) with a four times greater incidence of VTE (IRR 4.4, P = 0.001, Poisson regression). Patients treated with IV iron were significantly less likely to develop platelets of ≥350,000 cells/uL (IRR 0.7, P = 0.013, Poisson regression) and had a decreased incidence of VTE. Our study suggests that ESA associated VTE in CIA patients may be, in part, related to the thrombocytosis of ESA induced iron restricted erythropoiesis and may be countered by IV iron.

Parenteral iron therapy: a single institution's experience over a 5-year period.
Many patients require parenteral iron therapy for optimal correction of anemia, including cancer patients who require erythropoietic drugs. Available parenteral iron therapy options include iron dextran, iron gluconate, and iron sucrose. The purpose of this study is to summarize our institution's experience with parenteral iron therapy over a 5-year period, with a focus on comparative safety profiles. All patients receiving parenteral iron therapy over this period were included in the analysis. Chi-squared test and Fisher's exact test were used to compare the adverse event rates of each product. A total of 121 patients received 444 infusions of parenteral iron over this period. Iron dextran was the most commonly used product (85 patients) and iron sucrose was the least used (2 patients). Iron gluconate was used by 34 patients. Overall adverse event rates per patient with iron dextran and iron gluconate were 16.5% and 5.8%, respectively (P = .024). Premedication with diphenhydramine and acetaminophen before infusions of iron dextran reduced adverse event rates per infusion from 12.3% to 4.4% (P = .054). Test doses of iron dextran were used 88% of the time for initial infusions of iron dextran. All adverse events for all parenteral iron products were mild or moderate. There were no serious adverse events and no anaphylaxis was observed. Our results suggest that, if test doses and premedications are used, iron dextran is an acceptable product to treat iron deficiency.
