title: Randomized double-blind study evaluating the efficacy on uterine fibroids shrinkage and on intra-operative blood loss of different length of leuprolide acetate depot treatment before myomectomy.
abstract: OBJECTIVE
  To determine whether length of pre-operative treatment with gonadotrophin-releasing hormone agonists (GnRHa) may have different effects on uterine shrinkage and intra-operative blood loss, 36 patients with symptomatic uterine fibroids awaiting myomectomy were randomly divided into two groups.
  
  
  METHODS
  Twenty patients received long-term GnRHa administration, six monthly depot injections of leuprolide acetate (LA), while 16 patients were treated with two monthly LA injections before surgery. The hemoglobin concentration and estradiol, follicle-stimulating hormone and luteinizing hormone concentrations were measured before and after treatment in both groups.
  
  
  RESULTS
  Uterine volume decreased in the long-term treated group from 680+/-276 cm3 to 486+/-195 cm3 (36%) after two and to 388+/-172 cm3 (51%) after six LA injections. In the short-term treated group the basal uterine volume decreased from 745+/-320 cm3 to 456+/-177 cm3 (39%) after two LA injections. The uterine volume decrease was statistically significant (p<0.05) after two LA injections in both groups while the decrease observed between two and six LA injections was not significant (p>0.05). The intra-operative blood-loss was not significantly different between the two groups studied, 315+/-93 cm3 and 336+/-88 cm3.
  
  
  CONCLUSIONS
  Two pre-operative GnRHa depot injections offer similar results, in terms of uterine shrinkage and intra-operative blood loss, and a longer treatment seems to be justified in cases of anemia.
