胃癌是全球重要的健康问题,尽管其发病率已明显下降,但仍居癌症发病率的第4位,死亡率的第2位,每年约有70万例患者死于胃癌。胃癌往往发展至进展期时,患者才出现明显的临床症状,此时治疗的疗效非常有限,故胃癌的死亡率较高。少数国家如日本具备有效的胃癌筛检策略,对早期胃癌的检出率较高。早期检出并采取胃切除或内镜下黏膜切除胃癌,可提高其治愈的概率。
Gastric cancer is an important health problem in the world. Although its incidence has dropped significantly, it still ranks 4th in the incidence of cancer and 2th in the mortality rate. About 700,000 patients die of gastric cancer each year. Gastric cancer tends to progress to advanced stage, the patient showed obvious clinical symptoms, this time the treatment effect is very limited, so the higher the mortality rate of gastric cancer. A few countries such as Japan have an effective gastric cancer screening strategy and a higher detection rate of early gastric cancer. Early detection and take gastrectomy or endoscopic mucosal resection of gastric cancer, can improve the probability of its cure.
