Dynamic reorganisation of intratumoural bacterial florae during colorectal cancer progression.
Article in British journal of cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundColorectal cancer (CRC) exhibits distinct bacterial community compositions compared to healthy mucosae, which intimately correlate with CRC clinical outcomes. There is a lack of explanation for the inducements of microbiota remodelling.
methodsFISH experiments and 16S rRNA sequencing were conducted to determine the inducements of various bacterial colonisation within tissues. Community cultivation was conducted to estimate the capacity of tumours to remodel bacterial communities. Metagenomic analyses were utilised to determine the remodelled communities of CRC with distant metastasis. Scratch tests and three-dimensional (3D) cultivation were employed to investigate the influence of specific taxa on tumour cell behaviours.
resultsColorectal tumours exhibit heterogeneous and individualised preferences in constantly remodelling intratumoural bacterial florae. Various degrees of colorectal gland differentiation within tumours cause heterogeneous intratumoural bacterial colonisation. CRC progression further alters bacterial community composition. Particularly, Prevotella is significantly enriched in the newly established communities colonising the primary foci of metastatic CRC. Furthermore, Prevotella intermedia (P. intermedia) promotes the invasion, migration, and ectopic tumorigenesis of CRC cells.
conclusionsIndividual evaluation of the preference of tumours in microbiota may pave the way to the development of CRC therapeutic strategies, and Prevotella is an emerging genus worthy of clinical attention.
