大肠癌在我国是常见病,近十年来5年生存率徘徊在50%左右,而在西方国家进展也不大。日本结肠癌术后5年生存率,从60年代的45%上升至80年代的78%,其最主要的原因是早期发现和手术技巧的改进。显而易见,提高结肠癌术后生存率和降低结肠癌死亡率的关键,就在于早期发现、早期诊断和早期治疗及术 Colorectal cancer is a common disease in our country. The 5-year survival rate in the past decade has hovered around 50%, and there has been little progress in Western countries. The 5-year survival rate of colon cancer in Japan has risen from 45% in the 1960s to 78% in the 1980s. The main reason for this is the early detection and improvement of surgical techniques. Obviously, the key to improving the survival rate of colon cancer and reducing the mortality of colon cancer lies in early detection, early diagnosis and early treatment and surgery.
