根据世界卫生组织(WHO)统计,每年胃癌新发病例约100万[1],中国、日本和韩国是高发地区,我国每年新发病例约40万。外科手术目前仍是胃癌的主要治疗手段,但疗效不甚理想,进展期胃癌5年生存率徘徊在30%左右[2]。病期是影响胃癌预后的主要因素之一。但病期相同、生物学行为不同的胃癌预后却大不相同,说明胃癌生物学行为亦具有重要意义。现代外科治疗应建立在胃癌生物学行为的基础上,根据不同病期制定合理而规范的治疗方案。
According to the statistics of the World Health Organization (WHO), there are about 1 million new cases of gastric cancer each year [1]. China, Japan and South Korea are the high incidence areas. About 400,000 new cases occur each year in our country. Surgery is still the main treatment of gastric cancer, but the effect is not ideal, advanced gastric cancer 5-year survival rate hovering around 30% [2]. Sickness is one of the main factors affecting the prognosis of gastric cancer. However, the same period of disease, different biological behavior of gastric cancer is very different prognosis, indicating that biological behavior of gastric cancer is also of great significance. Modern surgical treatment should be based on the biological behavior of gastric cancer, according to different stages of the development of a reasonable and standardized treatment.
