RESUMO
Colorectal cancer is a disease with high morbidity and mortality. Colorectal cancer has a poor prognosis, duing to the current limited treatment methods and can not achieve satisfactory treatment results. Therefore, how to diagnose colorectal cancer patients early and improve the prognosis has always been one of the problems in the medical and scientific research circles. As researchers gradually learn more about the intestinal flora including Fusobacterium nucleatum, the targeted treatment has been applied to the experimental research and clinical treatment of colorectal cancer. This paper reviews the research progress of Fusobacterium nucleatum on the pathogenesis, early diagnosis, prognosis and treatment of colorectal cancer in recent years.
