This is a randomized controlled trial to evaluate the use of LASER, Micro Ablative radiofrequency and topic promestriene to treat symptoms of vulvovaginal atrophy of women treated for breast cancer.
Women treated for breast cancer with moderate or severe signs or symptoms of vulvovaginal atrophy will be eligible for the study.
The patients will be randomized to receive one of the three intravaginal therapies: LASER, Micro Ablative radiofrequency or Promestriene. The applications will occur in the interval of 30 days for 3 times, for LASER and Radiofrequency groups. For the promestriene group, the application will be done by the patient, daily for 2 weeks and then twice a week for 3 months, and each 30 days, the patients will have an appointment when will be checked the weight of the promestriene tube, to verify the correct use.
The follow-up visits will occur 30, 90, 180 and 360 days after the conclusion of the third month of treatment.
Will be evaluated: vulvar and vaginal histology before and after the use of LASER, radiofrequency or estriol; microbiota and vaginal pH before and after the use of LASER, radiofrequency or promestriene; extracellular matrix and metalloproteinases in the remodeling of vulvovaginal collagen induced by promestriene, LASER and radiofrequency; quality of life, sexual dysfunctions and complains before and after the use of LASER, radiofrequency or hormones; metabolomics and vaginal microbiome.

|
| Micro Ablative Radiofrequency | Procedure | Use of Linly™ equipment to perform ambulatory intravaginal and vulvar application of fractionated microablative radiofrequency, to postmenopausal genitourinary syndrome. The patient will be in gynecological position, after remove of vaginal secretion, with gauze and under topic anesthesia, the radiofrequency will be applied, according to the protocol of the manufactured |
|
|
| Promestriene | Drug | The patient will perform self application of this vaginal promestriene daily for 2 weeks and after that the applications will occur twice a week. |
|
|
| Evaluation of vaginal pH before and after the use of intravaginal LASER, Micro ablative radiofrequency or topic promestriene |
The vaginal pH will be verified by the use of pH tape's. The results of the three groups will be compared |

The results of the three groups will be compared | The evaluation will occur pre-treatment and 30 180 and 360 days after treatment |
| Evaluation of extracellular matrix before and after the use of intravaginal and vulvar LASER, Micro Ablative radiofrequency or topic promestriene. | Evaluation of the composition and concentration of the glycosaminoglycans of extracellular matrix in the vaginal and vulvar biopsies by specific markers.

The results of the three groups will be compared | The evaluation will occur pre-treatment and 30 and 180 days after treatment |
| Evaluation of visual aspect of vulva after the use of intravaginal and vulvar LASER, Micro Ablative radiofrequency or topic promestriene. | Pictures of vulva will be taken before and after treatment. The images will be evaluated by a blind gynecologist and dermatologist regarding the type of treatment and the chronological order of the photos, which will classify the images as: better; equal or worse, in relation to tropism and number of vulvar skin grooves, The results of the three groups will be compared | The pictures will be taken before and 30 days and 180 days after treatment.] |
