: Vulvovaginal atrophy (VVA) significantly impacts the quality of life in breast cancer patients leading to symptoms like vaginal dryness, dyspareunia, and genital discomfort. Quality of life in this context is measured using validated scales like the Vaginal Health Index, Visual Analog Scale (VAS), and the Female Sexual Function Index (FSFI). : We performed a systematic review and meta-analysis to identify effective treatment options for VVA, including topical estrogen, systemic hormone therapy, vaginal DHEA, ospemifene, and non-hormonal methods like intravaginal laser therapy, moisturizers, and lubricants. A systematic search of four databases (MEDLINE, Scopus, CENTRAL, Embase) identified studies on VVA treatment efficacy in breast cancer patients, yielding 13,039 records, with 32 eligible studies and 8 included in the meta-analysis. : Significant improvements were found with intravaginal laser therapy, showing notable differences in the Vaginal Health Index (MD = 8.24, < 0.01), dyspareunia (MD = -4.82, = 0.05), and dryness (MD = -5.05, = 0.01). However, no significant changes were observed in FSFI and vaginal pH. Notably only intravaginal laser therapy was included in the meta-analysis, as other treatment options lacked comparable data. Both hormonal and non-hormonal treatments improved quality of life, with laser therapy showing the most substantial effects. : Intravaginal laser therapy is an effective treatment for VVA symptoms in breast cancer survivors, particularly in improving the Vaginal Health Index and reducing dyspareunia. Despite the strengths of the study, variability among studies, lack of RCT-s and data limitations, especially on long-term effects, present challenges.
