Plain language summary

A female health is one medical area of the framework strategies in predictive, preventive, and personalized (3P) medicine. Cervical cancer is preventable and successfully treatable at early stages that makes the disease as an ideal candidate applicable in the context of 3P medicine. The aim of this study was to examine the interaction of the cervical microbiome with epithelial cells in relation to inflammation, and to assess direct evidence of epigenetic changes related to the cervical microbiome. This study is a systematic review of publications in the field of cervical cancer research. This review shows that: - cervical cancer screening in future integration of precision cancer prevention regimes should match an individual’s risk of cancer in context with genomic and environmental factors. - identification of microbiome population might be one of the key aspects of precision medicine in the future. Microbial composition may early identify the potential risk of precancerous lesion formation or permanent bacterial vaginosis. - the composition of the microbiome can be influenced by dietary composition, which will also affect the epigenetic background of the microbiome. However, food forms the microbiome through epigenetic mechanisms, and it is thus necessary to clarify how cancer risk is increased due to food-related microbially produced metabolites. - an examination of the metabolites during inflammation of the cervical epithelium and bacterial vaginosis may improve the precise identification of inflammatory-induced biomarkers that could aid in the precision medicine in prediction of the risk of cervical dysplasia development. - cancer-associated inflammation pathways can be influenced by phytochemicals with anti-inflammatory effects on immune cells, suppression of proinflammatory transcription factors, cytokines, and chemokines. The biological balance between uncontrolled chronic inflammation and controlled inflammation is essential for cancer prevention, prediction, and prognostication. Authors conclude that their review highlighted the pivotal contribution of cervical microbiome, epigenetic changes, and inflammation to the formation of cervical intraepithelial lesion and progression to cervical cancer.

Abstract

One pillar of the predictive, preventive, and personalized medicine framework strategies is the female health. The evaluation of women's lifestyle and dietary habits in context with genetic and modifiable risk factors may reflect the prevention of cervical cancer before the occurrence of clinical symptoms and prediction of cervical lesion behavior. The main aim of this review is to analyze publications in the field of precision medicine that allow the use of research knowledge of cervical microbiome, epigenetic modifications, and inflammation in potential application in clinical practice. Personalized approach in evaluating patient's risk of future development of cervical abnormality should consider the biomarkers of the local microenvironment characterized by the microbial composition, epigenetic pattern of cervical epithelium, and presence of chronic inflammation. Novel sequencing techniques enable a more detailed characterization of actual state in cervical epithelium. Better understanding of all changes in multiomics level enables a better assessment of disease prognosis and selects the eligible targeted therapy in personalized medicine. Restoring of healthy vaginal microflora and reversing the outbreak of cervical abnormality can be also achieved by dietary habits as well as uptake of prebiotics, probiotics, synbiotics, microbial transplantation, and others.
