Abstract

Objective: To establish the etiological mechanisms of Streptococcus gallolyticus bacteremia in the development of colorectal cancer in 65-year-olds. Methods: A review of articles published in PubMed, BioMed Central, Scielo, Elsevier, Springer, among others, was carried out using the following keywords: Streptococcus bovis and colorectal cancer, Streptococcus gallolyticus and colorectal cancer, Streptococcus gallolyticus Streptococcus bovis and Association between Streptococcus bovis and colorectal cancer ". Results: A total of 568 patients with colorectal cancer and a total of 362 patients with colorectal adenomas presenting with S. gallolyticus bacteremia were determined from a total of 15 case reports from the 1974 to 2017 period. Patient age was reported in the 15 reports with an average of 65 years. Conclusions: It was concluded that the association between colorectal tumors with S. gallolyticus appears to be of etiological naturel. Evidence presented through 15 case reports retrospectively assessed from the period 1974 to 2017 shows that there is a fundamental relationship between S, bovis bacteremia and colorectal cancer.
