早期胃癌手术后五年生存率为90%,较晚的进展期胃癌术后五年生存率则为20～30%。单纯切除组的五年平均生存率为20.8～21.4%,而根治性切除组五年生存率则为31.2～41.5%。由此可见提高胃癌五年生存率的关键,在于准确而合理的施行根治性手术,因此,有必要从胃的胚胎、解剖学、胃癌淋巴转移及生物学特性等方面,对胃癌根治手术,加以认识提高及推广的必要。一、胃的淋巴引流与癌的扩散:从胚胎学观点说,胃与胰、脾、肝均从胚胎期前肠延伸而来,发育成器官后仍包裹在同一系膜之中,因而淋巴引流仍密切相关,因此胃癌的扩散,常常波及这些脏器的淋
The five-year survival rate after early gastric cancer surgery is 90%, and the late five-year survival rate of advanced gastric cancer is 20 to 30%. The 5-year survival rate for the simple resection group was 20.8 to 21.4%, while the 5-year survival rate for the radical resection group was 31.2 to 41.5%. This shows that the key to improving the five-year survival rate of gastric cancer lies in the accurate and reasonable implementation of radical surgery. Therefore, it is necessary to carry out radical surgery for gastric cancer from the aspects of stomach embryology, anatomy, lymph node metastasis, and biological characteristics. Recognize the need for improvement and promotion. First, the lymphatic drainage of the stomach and the spread of cancer: From the embryology point of view, the stomach and pancreas, spleen, liver are extended from the embryonic intestine, and after being developed into organs, it is still wrapped in the same mesangium, so lymphatic drainage Still closely related, so the spread of gastric cancer often affects the leaching of these organs.
