幽门螺杆菌（HP）感染已被证实与慢性萎缩性胃炎及肠上皮化生等公认的癌前期病变密切相关。区域性的研究发现血清HP阳性率与胃癌关系密切。据报告血清HP阳性率与胃癌的关系在世界不同区域约为69％～94％。本研究测定血清HP阳性率与伴随胃癌的关系，以确定是否可以将这一方法作
Helicobacter pylori (HP) infection has been shown to be closely associated with recognized precancerous lesions such as chronic atrophic gastritis and intestinal metaplasia. Regional studies have found that serum HP positive rates are closely related to gastric cancer. It has been reported that the relationship between serum HP positive rate and gastric cancer is approximately 69% to 94% in different regions of the world. This study determined the relationship between serum HP positive rate and concomitant gastric cancer to determine whether this method can be used
