胃癌的临床病理分期,由于胃癌位于腹腔内,目前的临床检查难于在术前确定其肿瘤侵润程度及转移情况,因此结合手术所见及术后病理检查予以分期。国际抗癌协会曾制定了胃癌的 TNM 分类法,然尚未被各国广泛采用,国内目前也缺乏统一的分期方法。现将 TNM分类法略加修改介绍于下,以便逐步制定我国统一的分类分期标准。T——原发肿瘤,为了便于估计肿瘤的范围及大小,可将胃划分为上、中、下三个区,在胃大小弯各分为三个等距的点,并将相应的上下点联结,上1/3包括贲门及胃底,中1/ In the clinical pathological stage of gastric cancer, since gastric cancer is located in the abdominal cavity, the current clinical examination is difficult to determine the degree of invasion and metastasis of the tumor before surgery. Therefore, it is combined with the surgical findings and pathological examination to be staging. The International Anti-Cancer Association has developed the TNM classification method for gastric cancer, but it has not yet been widely adopted by various countries. At present, there is also a lack of a unified staging method in the country. The TNM taxonomy is now slightly revised and introduced in order to gradually formulate a unified classification and staging standard in China. T - primary tumor, in order to facilitate the assessment of the scope and size of the tumor, the stomach can be divided into upper, middle and lower three areas, in the stomach size bends are divided into three equidistant points, and the corresponding point up and down Coupling, upper 1/3 including cardia and fundus, middle 1/
