Abstract: Recent researches of the association between helicobacter pylori (Hp) and colorectal adenocarcinoma have found that Hp infection rate is higher in the patients with colorectal cancer and other related colorectal adenoma, which suggest that Hp probably influence on local and distant intestinal mucosa epithelial cells achieve carcinogenesis by its own virulence and the role of elevated serum gastrin levels. Hp infection may be a potential risk factor of colorectal cancer.
