Dysbiosis may cause adverse outcomes, e.g., bacterial vaginosis, pelvic inflammatory disease and pregnancy complications. The cervicovaginal microbiome might contribute to the development of a persistent HPV infection\u2014the main risk factor of cervical cancer\u2014and influence progression to malignancy The aim is to perform a systematic review of current literature and a meta-analysis regarding microbiome changes after cervical intraepithelial neoplasia treatment. (2) Methods: We will search PubMed, Scopus, Google Scholar and Embase Database and trace citations in the reference sections. Randomized and non-randomized controlled studies, case\u2013control and cohort studies published between January 2000 and May 2021 will be included in the study protocol. The following keywords will be used: \u2018microbiome\u2019, \u2018vaginal microbiome\u2019, \u2018cervical microbiome\u2019, \u2018cervical neoplasia treatment\u2019, \u2019conization\u2019, \u2018electroconization\u2019, and \u2018electrosurgical treatment\u2019. Statistical analyses will be performed using RevMan 5.4. (3) Results: The results will be published as a peer-reviewed article. (4) Conclusions: The study will show which forms of intraepithelial neoplasia treatment change the cervicovaginal microbiome. Finding the best form of treatment by studying the cervicovaginal microbiome after various forms of treatment is essential. Patients would benefit not only from the treatment of the initial disease but also the management of dysbiosis, which might underlie other pathologies.<\/jats:p>","DOI":"10.3390\/ijerph18179050","type":"journal-article","created":{"date-parts":[[2021,8,27]],"date-time":"2021-08-27T09:53:23Z","timestamp":1630058003000},"page":"9050","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Cervicovaginal Microbiome after Cervical Intraepithelial Neoplasia Treatment.
