ABSTRACT:
Colon cancer is one of the most common types of cancer in the world and the second leading cause of death related to the disease in developed countries. Up to 75% of cases are associated with eating, indicating that a person can reduce their risk simply through dietary modification. Studies in animals show that various strains of lactic acid bacteria protect against colon cancer in rodents although data in humans are limited and conflicting. The aim of this study was to investigate the efficacy of acid lactic bacteria in the treatment and reduction of colon cancer in animal models. Systematic searches were conducted in electronic databases reaching 1079 related articles, only six articles were elected according instead of to the eligibility criteria for analysis. All reviewed articles showed satisfactory results on the inhibition of colon cancer in rats and mice when using predominantly Lactobacillus strains. This study can answer hypothesis that acid lactic bacteria has antitumor effect against colon cancer.
