Background
Menopause’s hypoestrogenic state which is characterized by atrophy can lead to incorrect interpretation of the cytological smears, as well as it can turn colposcopy challenging because of non-visualization of squamocolumnar junction. This study aims to determine the effect of estrogen therapy on the topography of the colposcopic transformation zone in hypoestrogenic patients and its effect on the differentiation of abnormal Papanicolaou smears secondary to atrophy and true intraepithelial lesions to improve the management of cervical disease after menopause.
Methods
This was a retrospective evaluation of postmenopausal women aged 50 years or older who were treated between January 2010 and February 2019 at a public hospital in southern Brazil and who had abnormal cervical cytologies and negative initial colposcopies and who were subjected to topical conjugated estrogen therapy and follow-up evaluations.
Results
Ninety-eight patients aged 57 years and 9.5 years after menopause were included. After 3 months of conjugated-topic estrogen therapy, the rate of satisfactory colposcopy ranged from 20.4–32.7%. Of the 78 (79.6%) subjects with a type 3 transformation zone in the entry colposcopy, 66 (67.3%) remained in the same topography. Additionally, of the 98 patients, 67 (68%) had negative cervical cytology results after treatment. Persistence of high-grade intraepithelial lesions was observed in 33.3% of the patients, 16.7% of whom were diagnosed with microcarcinoma.
Conclusion
The use of conjugated topical estrogen improved the accuracy of cytology smears in late postmenopausal women. However, it did not show a good response in the topography of the transformation zone and, consequently, a satisfactory colposcopy rate.
