Analysis of the Clinical Incidence and Correlation between Colorectal Cancer and Microorganisms

Abstract

In this single institution retrospective medical record review, patients diagnosed with colorectal cancer from the years 2018-2022 were evaluated to distinguish an associative linear relationship between diagnosed colorectal cancer and a positive result for the presence of a microorganism. Based on the clinical incidence of this occurrence, it was observed patients with tumors in the left side of the colon had a higher incidence of a positive test result with a dominant microorganism. Species evaluation within this cohort found similarity to microorganisms identified as colorectal cancer biomarkers. These findings support clinical relevance and warrant further consideration for prospective study regarding microorganism involvement in colorectal cancer.
