Erythropoietin or Darbepoetin for Patients with Cancer

Erythropoietin stimulating agents increased on-study mortality and worsened overall survival in cancer patients. Level of evidence: "A"

A Cochrane review [Abstract] 1 included 53 studies with a total of 13 933 cancer patients. The trials compared epoetin or darbepoetin plus red blood cell transfusions (as necessary) versus red blood cell transfusions (as necessary) alone to prevent or treat anemia in adult or pediatric cancer patients with or without concurrent antineoplastic therapy. A total of 1530 patients died on-study and 4993 overall. Erythropoietin stimulating agents increased on-study mortality (combined hazard ratio [cHR] 1.17; 95% CI 1.06-1.30) and worsened overall survival (cHR 1.06; 95% CI 1.00-1.12). Thirty-eight trials enrolled 10441 patients receiving chemotherapy. The cHR for on study mortality was 1.10 (95% CI 0.98-1.24) and 1.04 (95% CI 0.97-1.11) for overall survival. There was little evidence for a difference between trials of patients receiving different cancer treatments (P for interaction=0.42).
