糖尿病在近年的发病率逐年升高，胃癌的总体发病率虽有所下降，但是新发病例基数依然庞大，严重威胁人类健康。该文综述了近年来关于糖尿病和胃癌相关性的研究，发现糖尿病代谢紊乱可能影响胃癌发病率及死亡率，然而并没有明确的证据证明糖尿病是胃癌发病的危险因素，仍需要更多精心设计的流行病学研究来证实糖尿病与胃癌之间的关系。“,”In recent years, the incidence of diabetes has been increasing gradually. The overall incidence of gastric cancer has been decreasing, but the number of new cases is still large. Which has become the two most important diseases threaten the survival and health of human being. This article reviewed recent studies on the correlation between diabetes and gastric cancer.

Therefore, more well-designed epidemiological studies are needed to confirm the relationship between diabetes and gastric cancer.
