Abstract
The anemia that is most common in patients with solid tumors is the anemia of chronic disease, which probably occurs because of im paired production and a diminished response to serum erythropoietin (EPO). A number of trials evaluating recombinant human EPO in anemic cancer patients with a variety of solid tumors have demonstrated effective response rates, with increases in hemoglobin (Hb) concentra tion and reduction or elimination of transfusion requirements. The anemia of certain solid tu mors (eg, lung cancer, prostate cancer) appears to respond better to recombinant human EPO therapy than does the anemia associated with other cancers (eg, colon cancer). Both tumor response and increases in Hb concentrations are important factors in improving the quality of life of patients. The greatest contributor to improved quality of life appears to be the nor malization of Hb levels.
