The European Vulvovaginal Epidemiological Survey (EVES). Impact of history of breast cancer on prevalence, symptoms, sexual function and quality of life related to vulvovaginal atrophy.

Women with history of breast cancer (HBC) frequently suffer from vulvovaginal atrophy (VVA). European Vulvovaginal Epidemiology Survey (EVES) sub-analysis assesses the impact of HBC on VVA, sexual life and quality of life (QoL) in postmenopausal women. Women with at least one VVA symptom aged 45-75 years were included. EuroQol (EQ-5D-3L) and Day-to-Day Impact of Vaginal Aging (DIVA) questionnaires were filled to investigate QoL. VVA diagnosis was confirmed with objective gynecological examination. Comparison of postmenopausal women with and without HBC, and evaluation of treatment impact on VVA were performed. 1985 postmenopausal women without HBC and 175 with HBC were included. VVA was confirmed in 90.4% of women without HBC and 91.4% of women with HBC. There were no differences in VVA symptoms severity or vulvovaginal discomfort between groups. However, women with HBC who had completed treatment and had surgery 11-20 years previously versus those without HBC presented significantly worse Vaginal Health Index scores, as well as a higher prevalence of VVA objective diagnosis, although their overall symptom severity score was lower. Health status and QoL comparisons were similar. Results support a similar burden in terms of VVA prevalence and symptoms, QoL and sexual function in postmenopausal women with and without HBC.
