Serum Estradiol Levels In Postmenopausal Women With Breast Cancer Receiving Adjuvant Aromatase Inhibitors and Vaginal Estrogen
This trial is active, not recruiting.
|Conditions||atrophic vaginitis, breast cancer|
|Treatment||vagifem® (vaginal 17β-estradiol) questionnaire & menopause symptom checklist|
|Sponsor||Memorial Sloan Kettering Cancer Center|
|Start date||September 2009|
|End date||September 2017|
|Trial size||30 participants|
|Trial identifier||NCT00984399, 09-110|
The purpose of this study is to see if Vagifem® 10mcg is safe for women who have had breast cancer. Vagifem is an estrogen product. It is a tiny tablet that is inserted into the vagina. It relieves vaginal dryness. Women who have had breast cancer are usually told not to take estrogen. This is because estrogen use can lead to a breast cancer recurrence or a new primary breast cancer. It is unclear if the estrogen in Vagifem is only absorbed in the vagina. It may be absorbed into the blood stream for a short time and may cause a brief rise in your estrogen level. However, there is no clear evidence that this would cause any bad effects in patients with breast cancer. How much, if any, of these topical estrogens are absorbed through the vagina is not known. We also do not know what the impact is of low dose estrogen absorption on breast cancer outcomes. Also, the absorption should decrease as the mucus membranes are restored after estrogen exposure.

To determine the change in estradiol and follicle stimulating hormone (FSH) from baseline to twelve weeks in postmenopausal women receiving adjuvant aromatase inhibitors during treatment with low dose vaginal 10 µg 17- β estradiol.
time frame: 2 years
To compare the rise in estradiol in women on letrozole vs. anastrozole during treatment with low dose vaginal 10 µg 17- β estradiol to see if there are differences between aromatase inhibitors.
time frame: 2 years
To describe patterns of estradiol and FSH levels over the twenty-four week study period.
time frame: 24 weeks
To compare the patient's Female Sexual Function Index (FSFI) scores and menopause quality of life questionnaire at baseline, week 12 and week 24.
time frame: Week 12 and week 24
Female participants at least 18 years old.
