In controlled clinical studies, use of Epoetin alfa and other erythropoiesis-stimulating agents (ESAs) have shown: • shortened time to tumour progression in patients with advanced head and neck cancer receiving radiation therapy when administered to target a haemoglobin of greater than 14 g/dl (8.7 mmol/l), • shortened overall survival and increased deaths attributed to disease progression at 4 months in patients with metastatic breast cancer receiving chemotherapy when administered to target a haemoglobin of 12-14 g/dl (7.5 -8.7 mmol/l), • increased risk of death when administered to target a haemoglobin of 12 g/dl (7.5 mmol/l) in patients with active malignant disease receiving neither chemotherapy nor radiation therapy.
I kontrollerede kliniske forsøg har brug af epoetin alfa og andre erytropoiese- stimulerende stoffer (ESA' er) vist: • kortere tid til tumorprogression hos patienter med fremskreden hoved - og halscancer, som får strålebehandling, når stofferne administreres for at tilstræbe et hæmoglobinniveau, som er
