Anemia in Metastatic Breast Cancer

Comparing therapies: EPO vs best standard of care

Red blood cell (RBC) transfusion should be the preferred approach for the management of anemia in women with hemoglobin ≤ 11.0 g/dL receiving first- or second-line chemotherapy for metastatic breast cancer. This according to a study of 2,098 women with metastatic breast cancer who were randomly assigned to receive either EPO 40,000 IU subcutaneously once a week or best standard of care. Researchers found:

  • Median progression-free survival (PFS) was 7.4 months in both groups.

  • Median overall survival at clinical cutoff was 17.2 months in the EPO group and 17.4 months in the best standard of care group.
  • Median time to tumor progression in both groups was 7.5 months.
  • Overall response rate was 50% in the EPO group and 51% in the best standard of care group.
  • RBC transfusions were 5.8% vs 11.4% and thrombotic vascular events were 2.8% vs 1.4 in the EPO and best standard of care groups, respectively.
