Very little is known about erythropoietin treatment and quality of life in hormone refractory prostate cancer patients. A randomized Swedish study did investigate the influence of two different doses of epoetin beta on quality of life, hemoglobin level, need for red blood cell transfusion and safety, in the treatment of anemia in 180 patients suffering from advanced hormone-refractory prostate cancer. This study found the treatment to be safe and effective for the treatment in many of these patients. In many of these critically ill patients, the treatment improved quality of life and relieved fatigue symptoms.
