食管癌和贲门癌在我国北方为多发病.随着食管细胞采集器的出现和食管拉网方法不断应于用高发区的普查,不但发现了一些早期食管癌和贲门癌,同时也发现了更多的食管和贲门上皮癌前增生患者.这对于早期手术根治和癌前增生的研究,特别是寻找治疗食管上皮增生的有效药物,都是极其有利的.下面介纪一下早期诊断的方法和步骤。一、早期癌的确诊步骤:1、X 线检查:对普查拉网涂片发现癌细胞的患者均进行食管及贲门的钡餐透视检查,以确定病变之早晚。对于 X 线定为早期或阴性的病例,进
Esophageal and cardia cancers are frequently found in northern China. With the advent of esophageal cell harvesters and methods for esophageal pull-in should be used in the survey of high-risk areas, not only early esophageal and cardiac cancers were discovered, but also Many patients with esophageal and cardiac cancer have precancerous hyperplasia. This is of great benefit for the early surgical treatment and precancerous hyperplasia, especially the search for effective drugs for the treatment of esophageal epithelial hyperplasia. . First, the early diagnosis of cancer steps: 1, X-ray examination: The general screening of patients with cancer cells were found in esophageal and cardiac barium meal fluoroscopic perspective to determine the lesion sooner or later. For cases where the X-ray is considered early or negative,
