title: Decrease in symptoms, blood loss and uterine size with nafarelin acetate before abdominal hysterectomy: a placebo-controlled, double-blind study.
abstract: To evaluate the efficacy and safety of nafarelin before hysterectomy in a prospective placebo-controlled trial, we randomized 188 pre-menopausal women with uterine fibroids (n = 111), menometrorrhagia (n = 58) or pelvic pain (n = 19) to receive either nafarelin (200 micrograms twice daily as a nasal spray) or a placebo for 3 months before abdominal hysterectomy. The data analysis could be performed in 166 women, of whom 107 received nafarelin and 59 a placebo. Nafarelin led to a rise in blood haemoglobin (5.5 g/l) and to a decrease in uterine volume (23.7%). This, however, gave no objective benefit during surgery (similar operative durations and blood losses). The uteri from patients treated with nafarelin (255.5 +/- 12.6 g, mean +/- SD) were significantly lighter (P = 0.029) than those from patients treated with a placebo (346.2 +/- 35.7 g). Histological examination of the fibroids or uteri revealed changes typical for hypo-oestrogenism, but no specific histological pattern could be established. The endometrium was proliferative in 56% and showed mild hyperplastic features in 10% of patients given nafarelin, whereas the respective figures for the placebo group were 41 and 0%. Hot flushes were the most common side-effects, being reported by 61% in the nafarelin group and 35% in the placebo group. Nafarelin can be useful as a pre-surgical adjunct in a patient scheduled for abdominal hysterectomy if there is a need to raise the haemoglobin concentration or to reduce the size of the uterus.
