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.
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.
