Editor’s summaryErythropoietin (EPO) is a hormone that stimulates the production of red blood cells in the bone marrow. EPO-stimulating agents have been used to treat anemia in cancer patients, but some research has suggested that this treatment may negatively affect survival. Shedding light on this puzzle, Chiu et al. found that tumor cells require secreted EPO to evade immune attack (see the Perspective by Armouk and Van Ginderachter).
