Abstract
BACKGROUND: Microbiomes have been linked to oncogenesis, e.g. the intestinal microbiome and colon cancer or HPV-associated cervical cancer. A connection between microbiomes of different body cavities and tumor oncogenesis was shown. The gut microbiome's influence on bladder cancer was established, raising the question whether nearby microbiomes (rectum, vagina) also influence bladder cancer due to their proximity. OBJECTIVE: Considering the influence of various body cavities and the broader microbial components, this systematic review aims to investigate differences in the bladder, vaginal, and intestinal microbiota-including bacterial, viral, fungal and archaea-between patients with bladder cancer and healthy controls. METHODS: Databases (PubMed, Scopus, Embase) were searched until April 2022. Three types of studies were included: "(1) studies using bladder cancer and control groups (case-controlled studies) (2) studies that provided information on the presence or abundance of microbial taxa (3) studies that provided information on increased or decreased taxa in bladder cancer and/or control groups.". Risk of bias was assessed using the Newcastle Ottawa Scale. RESULTS: Fourteen studies (695 samples: 403 bladder cancer, 292 controls) were analyzed. Bacterial taxa that have been detected in at least two studies, the genera Geobacillus and Rubrobacter were more frequently in bladder cancer patients; while Streptococcus and Roseomonas were more prevalent in controls. No consistent taxa were identified across stool or bladder tissue samples. CONCLUSION: The microbiota in bladder cancer patients show significant variation across studies. Standardized methods and expanded investigations into viral and fungal components are needed to clarify the role of microbiota in bladder cancer.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
