流行病学数据显示,全球每年新发生胃癌近100万例,其中近半数发生在中国。由于缺乏全民普查机制,临床病例中90%为进展期患者。同样是胃癌高发地区的韩国和日本,由于早期病例比例高、规范化治疗得到普及,因此治疗效果明显提高,总体5年生存率达到70%以上。由于临床的绝大多数病例为进展期、规范化手术未得到推广,我国目前胃癌总体治愈率仍徘徊在20%~30%。
Epidemiological data show that nearly one million new cases of gastric cancer occur each year in the world, and nearly half of them occur in China. Due to the lack of a universal census mechanism, 90% of clinical cases are advanced patients. In South Korea and Japan, where high incidence of gastric cancer is also common, the proportion of early cases is high and standardized treatment is popularized. Therefore, the treatment effect has been significantly improved, and the overall 5-year survival rate has reached over 70%. As the vast majority of clinical cases are in advanced stages and standardized surgery has not been promoted, the current overall cure rate for gastric cancer in China is still at 20% to 30%.
