Chemotherapy-induced Anemia Associated with Breast Cancer Recurrence
Anemia has been associated with negative outcomes in several types of cancer following treatment with surgery, chemotherapy, radiation therapy, or a combination of treatments. The current study focused on the relationship between chemotherapy-induced anemia and breast cancer relapse. Participants included 424 premenopausal women being treated for localized breast cancer (cancer that has not spread beyond the breast).
Each patient in the study had been treated with combination chemotherapy including the drugs cytoxan, methotrexate, and 5-FU (CMF) as well as radiation therapy. Anemia was defined as hemoglobin of less than 12g/dl. During an average follow-up of five years, the following was observed:
These results indicate that chemotherapy-induced anemia may be associated with a higher rate of local breast cancer recurrence among premenopausal women, however anemia did not appear to affect overall survival or distant recurrence.
Premenopausal women who are undergoing treatment for localized breast cancer with chemotherapy may wish to discuss with their physician risk for anemia as well as approaches to prevent and manage chemotherapy-induced anemia.
