Infection by Helicobacterpylori, a microorgan living in the mucus layer of the stomach, has been implicated as one of the causes. Whether eradication of the bacteria can reverse the tendency for the cancer to develop is controversial. The Department of Medicine and Therapeutics and the Department of Surgery of the University have conducted a prospective study in Shangdong Province in China in collaboration with the Peking University Health Science Centre. A team from Hong Kong and Beijing visited the high incidence area and performed endoscopy on over 1,000 patients. The subjects were randomized to receive antibiotic treatment or placebo. A one- year follow-up indicates that treatment of Helicobacterpylori has reduced the rate of progression of pre-malignant lesions. The study received international acclaim when it was presented as a plenary paper in the American Gastroenterological Association meeting. 幽 門 螺 桿菌 Helicobacter pylori
