AI Article Synopsis
- The study aimed to analyze how two different hormone therapy regimens affect mammographic breast density in postmenopausal women.
- Conducted as a randomized clinical study in a university hospital, it involved women without prior breast disorders receiving either estradiol valerate/dienogest or estradiol/norethisterone acetate.
- Results showed that about 50% of participants had increased breast density after six months, regardless of the treatment, with significant correlations between the density increase and levels of certain hormones, particularly estradiol and sex hormone-binding globulin.
Article Abstract
Objective: To study the effect on mammographic breast density of two different continuous combined regimens for hormone therapy.
Design: Randomized clinical study.
Setting: University hospital.
Patient(s): Postmenopausal women without any previous history of breast disorder.
Intervention(s): The women received either estradiol valerate/dienogest or estradiol/norethisterone acetate. Mammograms and venous blood samples were obtained at baseline and after 6 months.
Main Outcome Measure(s): Change in mammographic breast density. Correlations with levels of hormones, growth factors, and binding proteins.
Result(s): An increase in mammographic density was recorded in approximately 50% of the women, and there were no differences between treatments. Increased density showed a positive correlation with estradiol, estrone, and sex hormone-binding globulin and showed a negative association to free T. Among hormonal factors, levels of free T were the most important for predicting increased density.
Conclusion(s): Continuous combined hormone therapy with different progestogens has a marked impact on the breast.
