The World Health Organization (WHO) reports that colorectal cancer is the third leading cause of death worldwide, making it a public health issue due to its high incidence. This research, titled "Influence of intestinal dysbiosis on the development of colorectal cancer," was developed as a critical review. The objective was to evaluate the available scientific research through a critical reading using the Critical Appraisal Skills Programme (CASPE) tool on studies published about the influence of intestinal microbiome alterations (intestinal dysbiosis) in the development of colorectal cancer. The clinical question was: Does intestinal dysbiosis influence the development of colorectal cancer? The methodology used was Evidence-Based Nutrition (NuBE). The search for information was conducted in WEB OF SCIENCE, SCOPUS, EMBASE, PUBMED, SCIELO, DOAJ, SCIENCE DIRECT, ERIHPLUS, HINARIN, finding 114 articles, with 17 selected and evaluated using the CASPE tool. The systematic review titled "Fusobacterium nucleatum in the colorectum, and its association with cancer risk and survival: a systematic review and meta-analysis" was selected, with evidence level II and a strong recommendation grade, according to the researcher’s opinion. The critical commentary concludes that intestinal dysbiosis, especially the increase of Fusobacterium nucleatum, plays an important role in the development and prognosis of colorectal cancer. However, more clinical trials in humans are needed to establish Fusobacterium nucleatum as a causal factor or biomarker for development, which could generate low-cost diagnostic tools, as well as prophylactic and/or therapeutic measures.

Effect of the use of probiotics (lactobacillus rhamnosus and bifidobacterium longum) in the prevention and control of intestinal dysbiosis. Systematic review.
(Universidad Privada Norbert Wiener, 2018-09-24) Vega Bazán, Dayana Joyanne; Bohórquez Medina, Andrea Lisbet
Objective: To determine the effect of probiotics (lactobacillus and Bifidobacterium) for the prevention and treatment of intestinal dysbiosis in adults. Materials and methods: Systematic review, based on the PRISMA statement and Cochrane Rob 2.0 collaboration. A systematic search was conducted in the databases Scopus, Web of Science, Embase, etc. Ten studies were selected for the final sample. The search strategy was 'Probiotics/intestinal dysbiosis/Clinical uses/Risk and safety/lactobacillus rhamnosus/bifidobacterium longum/Use therapeutic/Gut microbiome.' Results: Of the 10 articles, 9 mentioned probiotic treatments for the symptoms of intestinal dysbiosis (IBS and its subtypes), 2 of the 9 trials included FOS (inulin) in their probiotic composition, and 1 article focused on the treatment against diarrhea caused by Clostridium difficile. Seven out of 10 studies showed significant improvements in abdominal pain, abdominal distension, and intestinal permeability (p<0.01; p<0.01; p=0.01), respectively. Conclusion: The use of probiotics, specifically Lactobacillus rhamnosus and Bifidobacterium longum, used in 9 of 10 analyzed articles, reported a significant reduction (p<0.05) in the clinical symptoms typical of intestinal dysbiosis and also showed a preventive effect in individuals with an unaltered microbiota.
