New clinical and basic research with erythropoietin, or epoetin, is raising questions about whether the red blood cell growth factor, often given to cancer patients with chemotherapy-associated anemia and fatigue, might actually encourage cancer growth. Two recent trials of epoetin in cancer patients showed that it negatively affected survival, and a growing body of research by Harvard University scientists and others indicates that some cancer cells possess epoetin receptors that respond to exogenous epoetin by accelerating the growth and proliferation of certain cancer cells in vitro. And, as this issue of the Journal went to press, Johnson & Johnson announced that it was stopping a number of trials of its drug Procrit (epoetin alfa) because of a higher-than-expected
