ABSTRACT
Gut microbiota plays an important role in the development of colorectal cancer, such as Fusobacterium Nucleatum, Peptostreptococcus and Streptococcus thermophilus. At present, Surgery is the mainly treatment strategy of colorectal cancer patients, supplemented by postoperative radiotherapy and chemotherapy. The influence of gut microbiota on colorectal cancer is not limited to the tumor itself. After tumor resection, gut microbiota is still in a state of disorder, which will affect the short-term and long-term prognosis of patients. Therefore, understanding the relationship between gut microbiota and prognosis of colorectal cancer is helpful to improve the prognosis of patients and reduce postoperative complications. In this review, the author will summarize the influence of gut microbiota on short-term and long-term prognosis of colorectal cancer patients.
