Abstract
Cancer-related anaemia has a number of causes, not least the underlying malignancy itself which plays a role in suppressing erythropoiesis. Anaemia is often exacerbated by cancer treatments, in particular routinely used cytotoxic chemotherapy. Chronic anaemia of cancer is often characterized by inappropriately low levels of endogenous erythropoietin for the degree of anaemia, and manifests clinically with generalized hypoxia and resultant severe fatigue. Epoetin alfa is one recombinant form of erythropoietin, the primary human growth factor responsible for promoting proliferation and survival of erythroid progenitor cells. Epoetin alfa has been widely studied for the treatment of anaemia associated with renal failure and is now recognized as having significant potential in the management of cancer-related anaemia. Studies suggest that epoetin alfa is an effective treatment in a proportion of cancer patients with symptomatic anaemia. It also appears useful for the prevention of chemotherapy-induced anaemia. Studies in a number of different cancer settings have shown that epoetin alfa significantly increases haemoglobin and haematocrit, reduces transfusion requirements and improves quality of life for the patient.
