Erythropoiesis-stimulating agents (epoetin alfa, epoetin beta, and darbepoetin alfa) effectively improve haematological response and reduce red blood cell transfusion requirements in cancer patients with anaemia, but do not provide a survival advantage and may increase the risk of thrombotic events.

For cancer patients with anaemia, epo drugs effectively raise hemoglobin and reduce the need for blood transfusions, improving quality of life. However, they do not extend life and may increase clotting risks. Treatment decisions should weigh these benefits against the lack of survival advantage and potential side effects, adhering to safety guidelines that limit use in patients with higher baseline hemoglobin levels.

GoodQualifiesMEDIUM confidence
Epo is effective in improving haematological response and reducing RBCT requirements, and appears to have a positive effect on HRQoL. The incidence of side-effects and effects on survival remains highly uncertain. ... The update, based on 28 RCTs, suggests no difference (HR 1.03, 95% CI 0.88 to 1.21).

Why this rating

Based on a systematic review of 46 RCTs and meta-analysis, though heterogeneity and missing data introduce uncertainty.
