ABSTRACT

Gastric cancer is the most commonly seen gastrointestinal tumor in China. The risk factors of gastric cancer include regional environment, diet and living factors, Helicobacter pylori infection, precancerous lesions, heredity, etc. Studies have shown that ABO blood group system, as a genetic marker, has a certain relationship with the occurrence and development of gastric cancer. Since the relationship between type A blood and gastric cancer was first proposed in the 1950s, a large number of studies on blood type and gastric cancer have been carried out, but the results are not consistent. This article reviewed the research progress on relationship between ABO blood group and gastric cancer and its mechanisms.
