[The Power of the Gut Microbiome: Exploring New Perspectives in Colorectal Cancer Therapy].

The gut microbiome is involved in host physiology, including nutrition, metabolism, and immunity. It was recently known that dysbiosis of the gut microbiome has been implicated in several human diseases such as inflammatory bowel disease. It is altered by environmental factors such as diet, habit and lifestyle and has been directly and indirectly linked to the development and progression of colorectal cancer(CRC). Fusobacterium(F.)nucleatum, which causes periodontal disease, has been shown to play an important role in the initiation and development of CRC, although not as clearly as Helicobacter(H.) pylori in gastric cancer. Therefore, gut bacteria hold promise as a potential therapeutic approach to prevent or treat CRC. Although its clinical usefulness has not yet been demonstrated, future research such as metagenomics may open new avenues for CRC treatment with gut bacteria. Here, we reviewed the role of the gut microbial community in the development, progression, and prevention of colorectal carcinogenesis.
