Researchers in Brazil have reported that treatment of vaginal eribevym laser improves the condition of vaginal and sexual function in postmenopausal women with a history of breast cancer.
Over 60% of survivors of breast cancer are experiencing at least one symptom of the urogenital after treatment, and vaginal dryness is one of the most important biomarkers of sexual dysfunction in this group of women.
Oncologists are reluctant to prescribe local vaginal hormone therapy for these symptoms, said Dr. Ana LR Valadares from the State University of Campinas in Sao Paulo. Recent studies have shown improvement in sexual function after laser vaginal therapy, mainly with the help of a CO2 laser, in postmenopausal women with urogenital syndrome. It is believed that the treatment helps to stimulate collagen production, without causing tissue necrosis.
For the study, Dr. Valadares and his colleagues used the erbium laser for treating 24 postmenopausal women with breast cancer, and vaginal dryness, which did not use the vaginal hormone therapy within six months.
The median vaginal health index improved from 11.88 before the first session of the laser 15,63 to immediately before the second session and 17.38 to 30 days after the second treatment laser. Brief scan also showed the effectiveness of the treatment laser for excitation, and pleasure of orgasm. Laser treatment does not improve sexual desire, but the researchers say that this was not expected, because the female sexual desire is a complex condition and results from the interaction of biological components, beliefs and values.
"Vaginal Erbium laser represents a new therapeutic option to improve vaginal health and sexual function in postmenopausal women with a history of breast cancer - the researchers conclude -. Long-term consequences of the use of this technology for vaginal tissue should be examined in future studies with longer follow-up. "
Dr. Eric R. Falcon from the Faculty of Medicine at Stanford University in California, who was not involved in the study, studied the use of CO2 laser for urogenital menopausal syndrome, and is part of a group, which is developing an application for the American Society uroginekologii.
"Personally, I am not surprised by these results, as other laser research, mainly of CO2 lasers, showed similar promising results, - he explains -. But it is amazing how quickly these lasers work to improve symptoms If this is confirmed, the. lasers could eventually change the treatment of these patients. Physicians should be aware that vaginal dryness and pain during sexual intimacy are very common and debilitating condition in postmenopausal women, and more common in women who have undergone hormonal treatment for breast cancer. Vaginal lasers provide promising opportunities for the treatment of these patients, but the safety and effectiveness of these technologies must be proven in additional trials to use in practice. "
