Practitioners' practical model for managing cancer-related anemia.
Anemia is the most common hematologic abnormality seen in patients with cancer. Anemia is associated with debilitating symptoms and poorer health-related quality of life and may result in less than optimal disease/treatment outcomes. The high prevalence of anemia and the potential clinical and prognostic impact make it important to have a systematic approach to the diagnosis and treatment of cancer-related anemia. A rigorous diagnostic evaluation should be undertaken to identify the cause of anemia and guide appropriate treatment. Treatment of anemia with erythropoiesis stimulating proteins offers an alternative treatment to red blood cell transfusions and has been shown to improve quality of life for patients being treated for cancer. In addition, recent studies suggest improved cancer treatment outcomes. Data indicate that treatment with darbepoetin alfa, a novel erythropoiesis stimulating protein, improves hemoglobin levels and quality of life in anemic patients with cancer who are not receiving chemotherapy or radiotherapy. Symptoms of anemia, when searched for properly, are identified often at hemoglobin levels less than 12 g/dL. As the understanding of the importance of anemia grows, and more convenient methods of therapy become available, patients will benefit with a more proactive approach to early treatment or prevention of this complication of cancer and its treatment.
