The Influence of the Gut Microbiome on Cancer, Immunity, and Cancer Immunotherapy
Open accessAbstract
The microbiome is receiving significant attention given its influence on a host of human diseases including cancer. Its role in response to cancer treatment is becoming increasingly apparent, with evidence suggesting that modulating the gut microbiome may impact responses to numerous forms of cancer therapy. A working knowledge of the microbiome is vital as we move forward in this age of precision medicine, and an understanding of the microbiome’s influence on immune responses and cancer is key. It is also important to understand factors influencing the gut microbiome and strategies to manipulate the microbiome to augment therapeutic responses.

“they play such a large role in numerous host functions including immunity”
§ The influence of the gut microbiome on cancer, immunity, and cancer immunotherapy > The microbiome and immunity
What the sources say
- Could not verifycites Sender et al., 2016 sourceExperimental — accuracy not yet measured
The Results discuss where microbes reside and how many there are; the Discussion mentions microbiome metabolic capabilities but does not describe contributions to host functions. Searches for immunity, the immune system, and host functions found no passage addressing the claim in our copy. (LLM, conf=0.76)
- Supportedcites Morgan and Huttenhower, 2012 source
Section 6, “Host Interactions and Interventions,” describes the microbiota’s role in maturation of the host immune system and intestinal development. It also describes substantial contributions to metabolism and signaling, supporting the claim that microbiota contribute to multiple host functions, including immunity. (LLM, conf=0.93)

“beneficial effects from mice with a more “favorable” microbiota could be transplanted to other mice using FMT or co-housing”

What the sources say
- Supportedcites Sivan et al., 2015 source
The passage describing cohousing (Fig. 1E–H) says that TAC mice appeared to acquire the JAX mice’s stronger antitumor phenotype. The fecal-transfer passage (Fig. 2A–C) reports that giving JAX fecal material to TAC mice delayed tumor growth and enhanced tumor-specific T-cell responses. Together, these support transfer of the beneficial effects by either co-housing or fecal transfer. (LLM, conf=0.94)

“demonstrating significant differences in tumor outgrowth in genetically similar mice with differing gut microbiomes purchased from two separate vendors”
§ The influence of the gut microbiome on cancer, immunity, and cancer immunotherapy > The gut microbiota in response and toxicity to immunotherapy > The gut microbiota and immunotherapy
What the sources say
- Partly supportedcites Sivan et al., 2015 sourceExperimental — accuracy not yet measured
The passage describing the JAX and TAC comparison reports significantly different melanoma growth in genetically similar mice from two facilities. A later passage reports that anti–PD-L1 therapy was more effective in JAX mice, but the source describes PD-L1 blockade, not PD-1 blockade; the initial vendor comparison was of tumor growth before that treatment.

The Results (page unavailable) report that Faecalibacterium prausnitzii was enriched in responders receiving combined checkpoint therapy, and the Discussion (page unavailable) describes similar response findings from other studies. Our copy does not link F. prausnitzii or other Ruminococcaceae taxa to treatment toxicity; its statement about toxicity concerns antibiotic or probiotic use instead. (LLM, conf=0.86)
- Partly supportedcites Gopalakrishnan et al., 2018 sourceExperimental — accuracy not yet measured
The paper reports that Ruminococcaceae and the Faecalibacterium genus were enriched in melanoma patients who responded to anti-PD-1 therapy, and that higher Faecalibacterium abundance was associated with longer progression-free survival. The passages in our copy do not establish an association with treatment toxicity or identify F. prausnitzii specifically; they support the response portion of the claim, not the full across-studies statement. The supplied copy labels these passages with the paper title but gives no page numbers. (LLM, conf=0.88)

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.
A language model drew the claims from the paper on 2026-10-07, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-07 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
