Comparison of efficacy of GnRH agonist and intravenous iron therapy for preoperative correction of anemia in gynecologic patients / 대한산부인과학회지

ABSTRACT

OBJECTIVE: This study is aimed to compare the efficacy of GnRH agonist and intravenous iron therapy in women who need correction of anemia prior to hysterectomy for uterine myoma and adenomyosis. METHODS: We reviewed retrospectively the data of 105 patients with initial hemoglobin level under 10g/dl, who had undergone total abdominal hysterectomy after correction of anemia with GnRH agonist (Group 1) or intravenous iron therapy (Group 2) from January 2004 to April 2006. RESULTS: Initial hemogloblin level was not different between the two groups. After administration, hemoglobin level increased by 3.9+/-2.3 g/dl and 2.6+/-1.7 g/dl, respectively. Therefore, group 1 was superior in anemia correction (p<0.01). On postoperative 1st day, hemoglobin level was 10.3+/-1.6 g/dl and 9.0+/-1.0 g/dl. Correction duration was 7.8+/-4.7weeks (1-18weeks) in group 1 and 4.0+/-4.8weeks (1-30 weeks) in group 2. Shorter duration was needed for correction in group 2 (p<0.01). Surgically removed uterine weight was 391.4+/-195.1 gm and 630.6+/-648.9 gm, respectively. Uterine weight was heavier in Group 2 (p<0.01). CONCLUSION: In comparison of efficacy of GnRH agonist with intravenous iron therapy for the correction of preoperative anemia, corrected hemoglobin level was higher and removed uterine weight was smaller in group 1. But duration of therapy for the correction of anemia was shorter and cost-effectiveness was superior in group 2. Clinicians should consider the patients' condition prior to the selection of drug for preoperative anemia correction.
