Objective To determine the relationship between local microenvironment and cervical cancer (CC). Discovering differential florae and metabolites associating with CC. Design Observational study. Participants 10 LSIL patients, 10 HSIL patients, 10 CC patients and 10 healthy controls were enrolled in our study. Methods We performed 16S rDNA sequencing and metabolomic analysis in the cervicovaginal fluid to reveal the differential florae and metabolites during cervical carcinogenesis. Results Carcinogenesis was associated with alterations in microbiome diversity, individual taxa, and functions. Bacterial diversity was increased and the composition was changed by the influence of cervical cancer carcinogensis. Lactobacillus was significantly reduced in LSIL and CC patients. On the contrary, the relative abundance of Prevotella was significantly elevated in LSIL patients. Lipids were significantly declined in LSIL and HSIL patients compared to HC participants, and significantly elevated in CC compared to LSIL and HSIL patients. Pathway enrichment analysis found phenylalanine, tyrosine and tryptophan biosynthesis pathway was crucial in cervical carcinogenesis. Conclusions These results showed that microbic and metabolomic profiling are capable of distinguishing CC from precancer and highlighted potential biomarkers for the early detection of cervical dysplasia. These differential microorganisms and metabolites expected to become a potential tool to assist in the diagnosis of cervical cancer.
