Abstract
SUMMARY
Erythropoiesis-stimulating agents (ESAs) are widely used in oncology to correct the anemia associated with chemotherapy, although only 50–70% of patients show an optimal response, mostly because of functional iron deficiency (FID). As intravenous (IV) iron can overcome this FID, it has become an important adjunct to obtaining and maintaining adequate hemoglobin levels in patients with cancer receiving chemotherapy. In fact, six out of seven published randomized, controlled trials performed in cancer patients have demonstrated that IV iron given concomitantly to ESAs induces a faster and much more robust response than with ESAs alone. The possibility that giving only IV iron can also produce adequate hemoglobin responses requires further studies. However, there still exists some reluctance among many oncologists to use IV iron because of the poor safety profile observed in the past with the old iron preparations, in particular high-molecular-weight iron dextran. As the efficacy and safety of the new iron preparations have been proven, the use of IV iron should be considered in the management of anemia secondary to chemotherapy treatments.
