Abstract

Background: Cancer cachexia is characterized by a negative energy balance, muscle and adipose tissue wasting, insulin resistance, and systemic inflammation. Because of its strong negative impact on prognosis and its multifactorial nature that is still not fully understood, cachexia remains an important challenge in the field of cancer treatment. Recent animal studies indicate that the gut microbiota is involved in the pathogenesis and manifestation of cancer cachexia, but human data are lacking. The present study investigates gut microbiota composition, short‐chain fatty acids (SCFA), and inflammatory parameters in human cancer cachexia. Methods: Faecal samples were prospectively collected in patients ( N = 107) with pancreatic cancer, lung cancer, breast cancer, or ovarian cancer. Household partners ( N = 76) of the patients were included as healthy controls with similar diet and environmental conditions. Patients were classified as cachectic if they lost >5% body weight in the last 6 months. Gut microbiota composition was analysed by sequencing of the 16S rRNA V4 gene region. Faecal SCFA levels were quantified by gas chromatography. Faecal calprotectin was assessed with enzyme‐linked immunosorbent assay. Serum C‐reactive protein and leucocyte counts were retrieved from medical records. Results: Cachexia prevalence was highest in pancreatic cancer (66.7%), followed by ovarian cancer (25%), lung cancer (20.8%), and breast cancer (17.3%). Microbial α‐diversity was not significantly different between cachectic cancer patients ( N = 33), non‐cachectic cancer patients ( N = 74), or healthy controls ( N = 76) (species richness P = 0.31; Shannon effective index P = 0.46). Community structure (β‐diversity) tended to differ between these groups ( P = 0.053), although overall differences were subtle and no clear clustering of samples was observed. Proteobacteria ( P < 0.001), an unknown genus from the Enterobacteriaceae family ( P < 0.01), and Veillonella ( P < 0.001) were more abundant among cachectic cancer patients. Megamonas ( P < 0.05) and Peptococcus ( P < 0.001) also showed differential abundance. Faecal levels of all SCFA tended to be lower in cachectic cancer patients, but only acetate concentrations were significantly reduced ( P < 0.05). Faecal calprotectin levels were positively correlated with the abundance of Peptococcus , unknown Enterobacteriaceae , and Veillonella . We also identified several correlations and interactions between clinical and microbial parameters. Conclusions: This clinical study provided the first insights into the alterations of gut microbiota composition and SCFA levels that occur in cachectic cancer patients and how they are related to inflammatory parameters. These results pave the way for further research examining the role of the gut microbiota in cancer cachexia and its potential use as therapeutic target.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Members of Enterobacteriaceae, Gammaproteobacteria, and Veillonella tend to be more abundant in patients with cancer-associated cachexia.

    “Members of the Enterobacteriaceae family, including the typically pro-inflammatory Gammaproteobacteria class and Veillonella genus, tend to be more abundant among patients with cancer-associated cachexia12.”
  • Faecal acetate levels correlate inversely with calprotectin and tend to be reduced in cancer-associated cachexia.

    “Faecal levels of short-chain fatty acids (SCFAs), more specifically acetate, are associated with health-related stool taxonomic composition, and have a inverse correlation with inflammation-related calprotectin12 but tend to be reduced in patients with cancer-associated cachexia12.”

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.
