Cancer-related anemia is common and multifactorial in origin. Functional iron deficiency (FID) is now recognized as a cause of iron-restricted erythropoiesis and may be one of the major reasons for lack of response to treatment with Erythropoietic Stimulating Agents (ESAs). Numerous studies have shown that intravenous (IV), but not oral, iron therapy effectively provides sufficient iron for optimal erythropoiesis in anemic patients with chronic renal disease receiving ESA therapy. The use of IV iron has also been suggested in the cancer setting. Six recent studies have tested this assumption and are summarized in this review. Four formulations of IV iron are available in Europe, with different pharmacokinetics, iron bioavailability, and risk of acute adverse drug reactions.. Limited iron stores and FID are common causes of response failure during ESA treatment in cancer patients and should be diagnosed. There is now substantial scientific support for the use of IV iron supplementation to improve response and this has been acknowledged in international and national guidelines. Prospective long-term data on the safety of IV iron in this setting are still awaited. Recommendations concerning the optimal formulation, doses, and schedule of iron supplementation to ESA treatment in cancer-related anemia are provisional awaiting data from prospective, randomized trials.

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.

This report describes the results of an observational, retrospective cohort study, evaluating the use of iron sucrose (IS) and red blood cell (RBC) transfusions in patients with cancer in routine clinical practice in France. A parallel investigated cohort treated with ferric carboxymaltose (FCM) has been reported earlier.. Data of patients with a solid tumour or haematological malignancy who have received IS or an RBC transfusion during 2010 from 3 months prior (M. Both IS and RBC transfusions effectively increased Hb levels in patients with cancer. IS was safe and well tolerated in this population. Considering prior reported results with FCM, using FCM may reduce ESA dose requirements and the required number of infusions.

Anemia is a major cause of morbidity in patients with cancer resulting in poor physical performance, prognosis and therapy outcome. The aim of this study is to assess the efficacy of intravenous (iv) iron administration for the correction of anemia, for the prevention of exacerbation of anemia, for decreasing blood transfusion rates, and for the survival of cancer patients.. Patients with different solid tumor diagnosis who received iv iron during their cancer treatment were evaluated retrospectively. Sixty-three patients with hemoglobin (Hgb) levels between ≥ 9 g/dL, and ≤ 10 g/dL, and no urgent need for red blood cell transfusion were included in this retrospective analysis. The aim of cancer treatment was palliative for metastatic patients (36 out of 63), or adjuvant or curative for patients with localized disease (27 out of 63). All the patients received 100 mg of iron sucrose which was delivered intravenously in 100 mL of saline solution, infused within 30 min, 5 infusions every other day. Complete blood count, serum iron, and ferritin levels before and at every 1 to 3 months subsequently after iv iron administration were followed regularly.. Initial mean serum Hgb, serum ferritin and serum iron levels were 9.33 g/dL, 156 ng/mL, and 35.9 μg/dL respectively. Mean Hgb, ferritin, and iron levels 1 to 3 months, and 6 to 12 months after iv iron administration were 10.4 g/dL, 11.2 g/dL, 298.6 ng/mL, 296.7 ng/mL, and 71.6 μg/dL, 67.7 μg/dL respectively with a statistically significant increase in the levels (p < 0.001). Nineteen patients (30 %) however had further decrease in Hgb levels despite iv iron administration, and blood transfusion was necessary in 18 of these 19 patients (28.5 %). The 1-year overall survival rates differed in metastatic cancer patients depending on their response to iv iron; 61.1 % in responders versus 35.3 % in non-responders, (p = 0.005), furthermore response to iv iron correlated with tumor response to cancer treatment, and this relation was statistically significant, (p < 0.001).. Iv iron administration in cancer patients undergoing active oncologic treatment is an effective and safe measure for correction of anemia, and prevention of worsening of anemia. Amelioration of anemia and increase in Hgb levels with iv iron administration in patients with disseminated cancer is associated with increased tumor response to oncologic treatment and overall survival. Response to iv iron may be both a prognostic and a predictive factor for response to cancer treatment and survival.

Implantable central venous access port (portacath) is used to provide long-term venous access and to deliver chemotherapy in cancer patients. Intravenous iron complexes are frequently prescribed in this setting, and some physicians use a portacath for their administration. The aim of this survey was to assess the frequency of this practice and the reasons supporting it.. This declarative survey was conducted in France; 497 oncologists/hematologists were contacted to answer a survey on their practices regarding the administration of intravenous iron via a portacath.. A total of 141 recipients (29.5 %) completed the questionnaire. The intravenous iron complexes most frequently used were iron sucrose and ferric carboxymaltose, and 55.2 % of the responders reported using a portacath to administer intravenous iron complexes. The main reasons mentioned for this practice were ease of administration (27.9 %) and preservation of venous capital (27.6 %). The main reasons reported for not using a portacath to administer intravenous iron were a history of thrombosis (45.1 %) or potential drug interactions (17.7 %). Efficacy and safety were expected to be similar to those observed with peripheral administration. A 47.6 % of physicians declared that they usually did not observe adverse reactions after use of a portacath for iron administration. Intravenous iron administration was always planned after chemotherapy for 46.6 % of the responders and before chemotherapy for 38.2 %, whereas 15.3 % did not have any preference for either option.. Intravenous iron complexes (mainly iron sucrose and ferric carboxymaltose) are commonly administered through a portacath in cancer patients in France. The choice for this route of administration is supported by clinical considerations, but further studies are needed to confirm the efficacy and safety of this practice.

Anemia in patients with cancer who are undergoing active therapy is commonly encountered and may worsen quality of life in these patients. The effect of blood transfusion is often temporary and may be associated with serious adverse events. Erythropoiesis-stimulating agents are not effective in 30%-50% of patients and may have a negative effect on overall survival.. To assess the efficacy and feasibility of intravenous iron therapy in patients with cancer who have non-iron-deficiency anemia and who are undergoing treatment with chemotherapy without the use of erythropoiesis-stimulating agents.. Adult patients with solid cancers and non-iron-deficiency anemia were included. Ferric sucrose at a dose of 200 mg was given in short intravenous infusions weekly for a total of 12 weeks. Hemoglobin level was measured at baseline, every 3 weeks, and 2 weeks after the last iron infusion (week 14). Adverse events related to intravenous iron were prospectively reported.. Of 25 patients included, 19 (76.0%) completed at least three iron infusions and 14 (56.0%) finished the planned 12 weeks of therapy. The mean hemoglobin level of the 25 patients at baseline was 9.6 g/dL (median, 9.9 g/dL; range, 6.9 g/dL 10.9 g/dL). The mean change in hemoglobin level for the 15 patients who completed at least 9 treatments was 1.7 g/dL (median, 1.1 g/dL; range, -1.9 g/dL to 3.2 g/dL); it reached 2.1 g/dL (median, 1.3 g/dL; range, -0.2 g/dL to 4.6 g/dL; P = 0.0007) for the 14 patients who completed all 12 weekly treatments. Five (20.0%) patients were transfused and considered as treatment failures. No treatment-related adverse events were reported.. Intravenous iron treatment alone is safe and may reduce blood transfusion requirements and improve hemoglobin level in patients with cancer who are undergoing anticancer therapy. Further randomized studies are needed to confirm these findings.

Therapy of anemia raises hemoglobin (Hb) level which in turn improves quality of life. Venofer was tested in 20 anemic (grade 1) patients with various malignancies. The drug was administered in 3 courses, i/v, 200 mg at a 4-5 week interval during chemotherapy. Hb levels rose or remained unchanged in 75%; they fell mostly in cases of tumor progression. There was no correlation between Hb concentration and chemotherapy regimen--with or without platinum. Venofer treatment was followed by improvement in quality of life or by stabilization only in 73.3%. Quality of life improved by 9,3% (FACT-An) after an 1g/dl increase in Hb level. Venofer treatment prevented further anemia.

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.
