Therefore, strategies aimed at improving survival while minimizing treatment-related side effects are essential. Emerging evidence suggests that the gut and vaginal microbiomes influence cervical carcinogenesis, treatment response, and treatment-related adverse effects. This narrative review aims to summarize current evidence regarding the role of the gut and vaginal microbiomes in locally advanced cervical cancer and explores their potential clinical implications, including interactions with immunological mechanisms. Dysbiosis has been associated with chronic inflammation, impaired antitumor immune responses, reduced treatment efficacy, and increased toxicity, whereas a beneficial microbial composition appears to support improved therapeutic outcomes and reduced toxicity. In addition, microbiome-targeted interventions, including probiotics, show promise in modulating microbial composition, optimizing treatment outcomes, and mitigating treatment-related toxicity. Longitudinal studies integrating analyses of both the gut and vaginal microbiomes with immune infiltrates, patient-reported outcomes, and clinical treatment results are essential to clarify the therapeutic potential of microbiome-targeted interventions in personalized cervical cancer care. Particular attention should be given to interactions between the microbiome and immunotherapy, as immune checkpoint inhibitors are increasingly being incorporated into treatment strategies for locally advanced disease.<\/jats:p>","DOI":"10.3389\/fimmu.2026.1876914","type":"journal-article","created":{"date-parts":[[2026,8,25]],"date-time":"2026-08-25T13:55:57Z","timestamp":1787666157000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Microbiome-host interactions in locally advanced cervical cancer: the impact on chemoradiotherapy treatment outcomes and toxicity"],"prefix":"10.3389","volume":"17","author":[{"given":"Helena C.
