Abstract
Objecties: To assess the effect of different hormone replacement therapy regimens on myoma uteri in postmenopausal
period. Methods: Totally 46 patients with 60 myomas attending to Department of Obstetrics and Gynecology, Akdeniz
University School of Medicine between May 2000 and March 2001 because of postmenopausal symptoms and having
myoma uteri were included in this study. These patients were randomized for tibolone and transdermal hormonal
replacement therapy system. The patients who were taking hormonal replacement therapy, discontinued the treatments
and lost for follow-up were excluded from the study. Impact of the treatments on the size of myoma uteri was evaluated
6 months after starting the therapy. Size of myomas were evaluated by transvaginal sonography before and 6 months
after onset of the treatment. Results: Mean age was 57.3 (50–70) and mean gravida 3.6 (1–6) for all the patients.
Although, increase in the size of myoma uteri was frequent in transdermal HRT, it was not statistically significant.
Conclusion: There are no statistical significant differences between tibolone and transdermal hormonal replacement
therapy regimens in respect to increase in the size of myoma uteri. © 2002 Published by Elsevier Science Ireland Ltd.
