Leuprorelin and triptorelin: new indication. Preoperative treatment of uterine leiomyoma: no proven value.
(1) The reference treatment for uterine leiomyoma with major symptoms is surgery. (2) Leuprorelin and triptorelin, two Gn-RH analogues, are the first drugs to be licensed in France for preoperative treatment of uterine leiomyoma associated with anaemia, when a reduction in the size of the leiomyoma is necessary to facilitate or modify the surgical technique. (3) A double-blind placebo-controlled trial of leuprorelin in nearly 300 anaemic women showed no advantage in terms of the need for non autologous transfusion. (4) Three double-blind placebo-controlled trials have shown that leuprorelin reduces the volume of uterine leiomyomas, but whether or not this facilitates or modifies the surgical technique is not known. An unblinded trial versus lynestrenol in non anaemic women showed a superior effect of leuprorelin on the size of the leiomyoma, but again there were no data on a possible effect on the choice of surgical technique. (5) In the absence of comparative double-blind trials, the observed effects of triptorelin on the choice of surgical technique are uninterpretable. (6) The adverse effects of leuprorelin are mainly linked to its hormone effect, i.e. flushing, headache, vaginitis and vaginal dryness. There are no recent reviews of the adverse effects of triptorelin in this setting. (7) In practice, for anaemic women with leiomyomas requiring surgery, there is no proof that leuprorelin and triptorelin have any tangible clinical advantages.
