Abstract

OBJECTIVES:

To compare the effect of the gonadotrophin-releasing hormone agonist leuprorelin and progestin lynestrenol, given prior to surgical treatment of symptomatic uterine myomas, on the pre-operative symptoms, tolerance, and operative blood loss.

STUDY DESIGN:

Fifty-six women were randomly selected to receive, during 16 weeks, either monthly subcutaneous injections of leuprorelin 3.75 mg sustained release (n=33) or lynestrenol 5 mg two tabs per day (5th to the 25th menstrual cycle) (n=23).

RESULTS:

Intent-to-treat analysis of the main efficacy criterion, namely ultrasonographic reduction of myoma(s) diameter, showed a significant difference in favour of leuprorelin (P=0.02) with a mean decrease of 26.5+/-4.5% (n=29) as opposed to 7.3+/-5% in the lynestrenol group (n=17). Clinical improvement was satisfactory in both groups. Hematocrit decrease between the preoperative value and the value measured 48 h postoperatively was significantly lower in the leuprorelin group than in the lynestrenol one (P=0.02) (for hemoglobin: P=0.07).

CONCLUSION:

Leuprorelin was more effective than lynestrenol because of its more intense antigonadotropic activity. The tolerance was good, reflecting each drug mechanism of action.
