食管贲门上皮细胞重度增生(重增),是一组患癌的危险人群,但其癌变又是在一个相当长的渐进的有时是相互转变的复杂过程中形成的。癌从发生到发展为中晚期癌要有10～20年的时间,如在肿瘤未形成之前采用药物对其进行干扰、阻断,促其逆转,可达到防癌之目的。对此国内外已作了些工作,但结果不甚一致,其中一个重要因素是细胞学诊断及细胞学疗效判断中有诸多的影响因素,想法消除这种因素,把细胞学诊断控制在相对准确能反应机体细胞客观变化可
The severe hyperplasia (re-increase) of esophageal epithelial cells is a group of people at risk of cancer, but its canceration is formed in a fairly long process of gradual, sometimes mutual transformation. From the occurrence to the development of cancer, it takes 10 to 20 years for the cancer to develop in the middle and advanced stages. If the tumor is not formed before it is formed, it can be interfered with and blocked by the drug to promote its reversal, which can achieve the purpose of preventing cancer. Some work has been done at home and abroad, but the results are not very consistent. One of the important factors is that there are many influencing factors in the diagnosis of cytology and cytology efficacy. The idea is to eliminate this factor and control the cytological diagnosis to be relatively accurate. Can respond to the objective changes in the body cells
