OBJECTIVE: To evaluate the changes of vaginal microbiota during cervical carcinogenesis in women with high-risk human papillomavirus infection. MATERIALS AND METHODS: Vaginal microbiota was analyzed using next-generation sequencing in women with normal, cervical intraepithelial neoplasia (CIN), or cervical cancer. RESULTS: A marked decrease of Lactobacillus crispatus was found in the CIN/cancer groups compared with that in the normal group. The diversity of microorganisms increased in patients with CIN or cervical cancer with HPV infection. Atopobium vaginae (OR 4.33, 95% CI 1.15-16.32), Dialister invisus (OR 4.89, 95% CI 1.20-19.94), Finegoldia magna (OR 6.00, 95% CI 1.08-33.27), Gardnerella vaginalis (OR 7.43, 95% CI 1.78-31.04), Prevotella buccalis (OR 11.00, 95% CI 2.00-60.57), and Prevotella timonensis (OR 6.00, 95% CI 1.46-24.69) were significantly associated with the risk of CIN 2/3 or cervical cancer. CONCLUSION: Women with the CIN and cervical cancer showed a high diversity in vaginal microbiota. Depletion of Lactobacillus crispatus and increased abundance of anaerobic bacteria were detected in women with cervical disease.
