Effect of Letrozole on endometriosis -related pelvic pain
2014
Background: To determine the role of Letrozole, an aromatase inhibitor, in the treatment of endometriotic pain.
Methods: In this prospective, randomized, controlled clinical trial in minimally invasive surgery research center, 51 women with pelvic endometriosis and endometriotic pain (dyspareunia, dysmenorrhea, pelvic pain) score of 5 or more (for at least one of these endometriotic pain), after laparoscopic diagnosis and conservative laparoscopic surgery were treated with either Letrozole plus OCP (n=25) or only OCP (n=26) for 4 months continuously.
Results: Using VAS test, the score of dyspareunia, dysmenorrhea and pelvic pain 4 months after the laparoscopic surgery declined significantly in both groups but the difference between results of the two groups was not significant.
Conclusion: Both treatment modalities showed comparable effectiveness in the treatment of pains related to endometriosis and in comparison with OCP, Letrozole did not affect the outcome.
