An increasing body of research indicates that the circulating microbiome plays a significant role in cancer initiation and progression treatment response. The genomic characteristics microorganisms may influence tumor immune microenvironment, thereby affecting therapeutic outcomes. However, whether can serve as prognostic biomarker for cervical patients its mechanistic microenvironment still requires further investigation. Univariate, Lasso, multivariate Cox regression analyses were utilized to identify microbial signatures associated with overall survival (OS) cancer. A Microbial Abundance Prognostic Score (MAPS) model was constructed based on these findings. nomogram integrated clinical features MAPSs developed predict OS rates Blood data combined matched RNA-seq analyze differences between high- low-MAPS groups, elucidating impact MAPS microenvironment. Finally, potential application predicting efficacy immunotherapy chemotherapy assessed. predictive model, which includes 15 microorganisms, has shown independent value Integrating into improved accuracy predictions. Combined gene revealed interactions microbiomes drug sensitivity analysis indicated predictor chemotherapy’s efficacy. Our findings suggest hold promise novel biomarkers inform personalized strategies Further large-scale multicenter studies are warranted validate utility MAPS.

Abstract Intratumoral microbiota (ITM) are microorganisms present in tumor cells. ITM participate development by affecting cells directly and the microenvironment (TME), indirectly. Alterations instigate changes DNA, activate oncogenic pathways, induce inflammatory responses, disrupt normal immune activity, facilitate secretion of effectors leading to progression, metastasis, or diminished therapeutic effects. varies significantly different types cancer disease states. The presence certain serves as a predictor various Thus, predicts tumorigenesis, grade, treatment efficacy, prognosis, making it potential biomarker. study aimed determine mechanisms which affects development, especially through TME; highlight significant enhancing diagnosis prognosis; outline future directions for research, with focus on innovative markers.

This review provides an overview of research evidence focused on the microbial components essential to clinical cancer care, called oncobiota (the interaction human microbiota and cells). It specifically examines in central nervous system cancer,breast cancer, pancreatic liver lung cervical cancer. The literature reveals insufficient knowledge about organs once considered sterile. Many studies focus small, geographically specific patient groups, absence a reference (control) group complicates development profiles for selected cancers. Consequently, this aims analyze data reports role "sterile" resulting therapeutic or preventive implications. All relevant publications patients with cancers were provide most thorough analysis possible. Understanding significance pathomechanisms carcinogenesis may pave way targeted prevention methods.

Abstract Background Ovarian serous cystadenocarcinoma, accounting for about 90% of ovarian cancers, is frequently diagnosed at advanced stages, leading to suboptimal treatment outcomes. Given the malignant nature disease, effective biomarkers accurate prediction and personalized remain an urgent clinical need. Methods In this study, we analyzed microbial contents 453 cystadenocarcinoma 68 adjacent non-cancerous samples. A univariate Cox regression model was used identify microorganisms significantly associated with survival a prognostic risk score constructed using LASSO analysis. Patients were subsequently categorized into high-risk low-risk groups based on their scores. Results Survival analysis revealed that patients in group had higher overall rate. nomogram easy visualization model. Analysis immune cell infiltration checkpoint gene expression both showed parameters positively correlated level, indicating increased response groups. Conclusion Our findings suggest profiles may serve as viable indicators.

The role of the microbiome in cancer and its crosstalk with tumor microenvironment (TME) has been extensively studied characterized. An emerging field research is concept intratumoral microbiome, which refers to residing within tumor. This primarily originates from local tumor-bearing tissue or translocating distant sites, such as gut. Despite increasing number studies on it remains unclear whether a driver bystander oncogenesis progression. review aims elucidate intricate development by exploring effects reshaping multileveled ecosystem tumors thrive, TME. To dissect complexity multitude layers TME, we distinguish six specialized microenvironments, namely, immune, metabolic, hypoxic, acidic, mechanical innervated microenvironments. Accordingly, attempt decipher each ultimately decode tumor-promoting tumor-suppressive impact.
