Abstract

Several studies have investigated links between the gut microbiome and colorectal cancer (CRC), but questions remain about the replicability of biomarkers across cohorts and populations. We performed a meta-analysis of five publicly available datasets and two new cohorts and validated the findings on two additional cohorts, considering in total 969 fecal metagenomes. Unlike microbiome shifts associated with gastrointestinal syndromes, the gut microbiome in CRC showed reproducibly higher richness than controls (P < 0.01), partially due to expansions of species typically derived from the oral cavity. Meta-analysis of the microbiome functional potential identified gluconeogenesis and the putrefaction and fermentation pathways as being associated with CRC, whereas the stachyose and starch degradation pathways were associated with controls. Predictive microbiome signatures for CRC trained on multiple datasets showed consistently high accuracy in datasets not considered for model training and independent validation cohorts (average area under the curve, 0.84). Pooled analysis of raw metagenomes showed that the choline trimethylamine-lyase gene was overabundant in CRC (P = 0.001), identifying a relationship between microbiome choline metabolism and CRC. The combined analysis of heterogeneous CRC cohorts thus identified reproducible microbiome biomarkers and accurate disease-predictive models that can form the basis for clinical prognostic tests and hypothesis-driven mechanistic studies. Multicohort analysis identifies microbial signatures of colorectal cancer in fecal microbiomes.

  • Streptococcus gallolyticus is potentially associated with disease, including colorectal cancer (11% prevalence vs. 3% in healthy controls).

    “Streptococcus gallolyticus is similarly potentially associated with disease, including colorectal cancer 112-114 (11% prevalence vs. 3% in healthy controls; Table S4), and was also prevalent in food.”

    From Unexplored microbial diversity from 2,500 food metagenomes and links with the human microbiome. (2024) · cites this paper as [112]

    The Results section ('A panel of microbial biomarkers for CRC is reproducible across cohorts'; page not provided) confirms Streptococcus gallolyticus as a relevant colorectal-cancer biomarker. Our copy does not report the claimed 11% prevalence in cases versus 3% in healthy controls, so it supports the association but not those figures. (LLM, conf=0.87)

  • The lack of solid cross-study reproducible microbial biomarkers of ICI response is not attributable to analytical choices, as applying the same meta-analysis methods in colorectal cancer confirmed strong and consistent biomarkers across cohorts.

    “The lack of solid cross-study reproducible microbial biomarkers of ICI response is not attributable to analytical choices, as applying the same meta-analysis methods in the context of colorectal cancer confirmed the strong and consistent biomarkers across cohorts described elsewhere13,14.”
  • Enrichment of bacterial species from oral cavity is characteristic of CRC GOMS, along with enrichment in invasive polymicrobial bacterial biofilms in patients with right-sided tumours.

    “The enrichment of bacterial species from the oral cavity is characteristic of the CRC GOMS50,76–79, along with an enrichment in invasive polymicrobial bacterial biofilms in patients with right-sided tumours76,80,81.”

  • A meta-analysis of metagenomic data found higher richness in colorectal cancer microbiomes than controls, partly from expansions of species typically from the oral cavity.

    “However, a meta-analysis of metagenomic data from different cohorts and populations found higher richness in microbiomes of CRC than controls, partly due to expansions of species typically derived from the oral cavity.16, 17”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
