Clinical experience with epoetin alfa in the management of hemoglobin levels in orthopedic surgery and cancer. Implications for use in gynecologic surgery.
Recombinant human erythropoietin (r-HuEPO, epoetin alfa) is used for treatment of anemia associated with chemotherapy for non-myeloid malignancies, chronic renal failure and zidovudine treatment in patients infected with the human immunodeficiency virus and for anemic patients undergoing elective, noncardiac, nonvascular surgery. Epoetin alfa has been shown to safely increase preoperative hemoglobin (Hb) levels in anemic patients undergoing elective noncardiac, nonvascular surgery and is more effective than preoperative autologous blood donation in reducing the need for perioperative blood transfusions in orthopedic surgery patients. Epoetin alfa was shown to significantly increase Hb levels and decrease transfusion requirements in gynecologic cancer patients undergoing chemotherapy. A once-weekly regimen of 40,000 IU per dose was effective in these patients. In addition to decreasing transfusion requirements and increasing Hb, epoetin alfa for relieving anemia-related fatigue and improving quality of life was demonstrated in clinical trials in anemic cancer patients receiving chemotherapy. With regard to quality of life in orthopedic surgery patients, a novel instrument to measure the effect of Hb management on postoperative recuperative power (i.e., vigor, functional ability) has been validated and may prove to be useful in optimizing rehabilitation and discharge planning. Extensive clinical experience with epoetin alfa in anemic patients undergoing major elective orthopedic surgery or those with gynecologic cancer provides a strong basis for its use in gynecologic surgery.
