Epoetin Alfa Therapy for Patients with Hematologic Malignancies and Mild Anemia

Abstract

Anemia has been reported in approximately 40%-70% of patients with hematologic malignancies, with severity depending on the type and stage of disease and whether the patient has received myelosuppressive chemotherapy. Growing evidence supports the role of epoetin alfa in correcting anemia and improving quality of life (QOL) in patients with hematologic malignancies. Clinical practice guidelines recommend the use of epoetin alfa in patients with cancer-related anemia (including patients with hematologic malignancies) and hemoglobin levels ≤ 10 g/dL. Epoetin alfa treatment is optional for patients with cancer-related anemia and hemoglobin levels > 10 g/dL and < 12 g/dL, depending on clinical circumstances. A prospective, open-label, randomized trial evaluating hematologic response, transfusion use, and QOL after immediate or delayed epoetin alfa treatment in mildly anemic patients (hemoglobin ≤ 12 g/dL) undergoing chemotherapy for chronic lymphocytic leukemia, multiple myeloma, or lymphoma was recently completed. Study objectives included determining any correlation between changes in hemoglobin level and QOL and assessing any correlation between QOL measures and health care resource use. Interim results suggest that epoetin alfa treatment in patients with hematologic cancers and hemoglobin ≤ 12 g/dL who are receiving chemotherapy increases hemoglobin, functional capacity, well-being, work and productivity, and health resource use. Further evaluation of alternative epoetin alfa dosing schedules and use of epoetin alfa in treating anemia in patients with specific hematologic malignancies is ongoing.
