Specimen collection was performed by an experienced physician. All samples were sequenced utilizing the shotgun approach. The microbial statistical analyses were conducted using R.Results: Compared to the non-cancerous group (BE and CIN), the index related to microbial community stability decreases significantly and the incidence of cervical canal dysbiosis increases in the cancerous group (EC and CC). Microbial diversity exhibited significant differences between BE and EC, CIN and CC, as well as cancerous and non-cancerous groups. At the species level, some species were significantly decreased (eg, Lactobacillus iners) and increased (eg, Staphylococcus haemolyticus, Pasteurella multocida, Pseudomonas putida, and other opportunistic pathogen) in the cancerous group.Conclusion: The cervical canal represents a distinct microbial niche, with its dysbiotic progression reflecting the trajectory of oncogenic transformation. The progression from non-cancerous to cancerous states is characterized by the replacement of the vaginal microbial community, which is dominated by Lactobacillus iners, with a gradual shift towards opportunistic pathogen. Disease diagnosis and complementary therapies focused on lactobacilli and hallmark opportunistic pathogen may offer new insights for precision oncology.Keywords: community succession, cervical canal microbiota, microbial dysbiosis, endometrial cancer, cervical cancer |
