The patients will receive 3 consecutive applications of intravaginal and vulvar CO2 LASER, according to the manufacturer protocol for vaginal atrophy. The applications will be separated by the interval of 30 days

The patients will receive 3 consecutive applications of intravaginal and vulvar MIcroablative radiofrequency, according to the manufacturer protocol for vaginal atrophy. The applications will be separated by the interval of 30 days

The patient will use intravaginal promestriene, daily for 2 weeks and them twice a week for 3 months . 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 patient will use intravaginal estriol, daily for 2 weeks and them twice a week for 3 months . Each 30 days, the patients will have an appointment when will be checked the weight of the estriol tube to verify the correct use.vulvar application of LASER, to postmenopausal genitourinary syndrome. The patient will be in gynecological position, after remove of vaginal secretion, with gauze and under topic anesthesia, the LASER will be applied, according to the protocol of the manufactured.

Use of Linly™ equipment to perform ambulatory intravaginal and vulvar application of fractionated microablative radiofrequency, to postmenopausal genitourinary syndrome.

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.

The patient will be randomized in block to receive one of the three intravaginal therapies: LASER, Radiofrequency and promestriene

LASER and Radiofrequency for Treatment of Vaginal Vulvar Atrophy (VVA) in Women Treated for Breast Cancer (EPMLARF-arm2)

LASER and Radiofrequency as Alternative Treatment of Vaginal Vulvar Atrophy in Women Treated for Breast Cancer

Will be applied a Visual Analogic Scale (0-10) to access the improvement of genitourinary signs and symptoms, the results of the three groups will be compared

Will be applied a LIKERT Satisfaction Scale (1-5) to access the satisfaction with the treatment, the results of the three groups will be compared

The vaginal flora will be evaluated by vaginal smear. The results of the three groups will be compared

The vaginal pH will be verified by the use of pH tape's. The results of the three groups will be compared

Thickness of epithelium (mm and number of layers), and evaluation of expression of Ki-67 and VEGF (vascular endothelial growth factor) will be done on vaginal and vulvar biopsies, in order to evaluate the tissue regeneration ( a greater the number of layers associated with the expression of VEGF and ki67 indicate a tissue regeneration, the combination of this measures, and not evaluation each one isolated, are important to evaluate histological improvement). The results of the three groups will be compared

The IQol (incontinence quality of life questionnaire, validated to portuguese language - score 0-100) will be used to evaluate quality of life .The results of the three groups will be compared

The FSF-I (Female Sexual Function Index , validated to portuguese language- score range from 2 - 36) will be used to evaluate sexual function . The results of the three groups will be compared

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

Evaluation of the tissue distribution of the MMP-1, MMP-2, MMP-3, MMP-7, MMP-9 metalloproteinases of collagen I, II, IV and elastin proteins by specific markers on vaginal and vulvar biopsies. The results of the three groups will be compared

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
