The emerging role of the microbiome in bladder cancer: prognostic implications and treatment response.
Review in Brazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologicas, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Bladder cancer (BCa) is a histologically and molecularly heterogeneous disease and is one of the leading causes of cancer death globally. The main risk factors are sex (with incidence 3 to 4 times higher in men), tobacco usage, occupational exposure to carcinogens, and persistent infections, such as those caused by Schistosoma haematobium. Urine and the bladder were recently confirmed to be non-sterile, prompting investigations into the urinary and intratumoral microbiomes and their roles in tumor stage, prognosis, and therapy response. In this context, the role of the urinary and intratumoral microbiome in bladder carcinoma is among the most promising areas in translational uro-oncology. Recent evidence demonstrates the presence and diversity of microbial communities in both urine and bladder cancer tissue, with patterns associated with tumor stage and prognosis. Chronic inflammation, genotoxin production, altered carcinogen metabolism, and modulation of the immune microenvironment are biological processes that provide a rationale for the functional role of these microorganisms in the bladder. Furthermore, microbial profiles have been correlated with responses to intravesical therapies (such as BCG - Bacillus Calmette-Guérin) and, potentially, with systemic immunotherapies. The microbiome can help identify predictors of treatment response and potential adjuvant interventions, and offers a non-invasive, translational pathway for diagnosis and surveillance. This review summarizes current evidence on the microbiome in bladder cancer patients and its prognostic and therapeutic potential.
