NCT04662853

Brief Summary

This clinical trial is focused in the development of a screening test for the people at risk of colo-rectal cancer (aged more than 50 years old), valid and safe, improving the screening prognosis increasing the sensitivity and sensitive as compared with the current method, fecal occult blood.

Outcome Measures

Primary Outcomes (1)

  • Gut-microbiota-based color-rectal cancer diagnosis.

    Determination of the gut microbiota composition by 16S metagenomic, data analysis and building of a mathematical model to test the potential use of the gut microbiota architecture as biomarker to color-rectal cancer prognosis in patients with positive results in fecal occult blood test.

    A week before colonoscopy.

Secondary Outcomes (3)

  • Colonoscopy clinical results.

    At week 2.

  • Characteristic of the population.

    A week before colonoscopy.

  • Dietary habits

    A week before colonoscopy.

Study Arms (1)

Patients with positive results in the fecal occult blood test.

Patients with positive results in the fecal occult blood test in the Program for Early Detection of Colon and Rectal Cancer, undergone by the Consejeria de Salud de la Junta de Andalucia (Spain), were invited to participate in the CCR-microbiome study. This program is screening Andalusian population aged between 50 and 69 years old for colo-rectal cancer presence by fecal occult blood test, and further colonoscopy when positive for this test. Patients included in CCR-microbiome study were recruited between January 2017 and March 2020, at the Reina Sofia University Hospital (Cordoba, Spain) with the consumption of antibiotic within the previous month as exclusion criteria.

Diagnostic Test: Gut microbiota determination from feces samples.

Interventions

Determination of the gut microbiota composition by 16S metagenomic and building of a mathematical model, on the basis of the colonoscopies results, able to classify patients without and with color-rectal cancer-related lessions. These latter will be also classified according to the type of lession.

Also known as: Colonoscopy
Patients with positive results in the fecal occult blood test.
