胃癌是常见的恶性肿瘤之一.在发达国家,其新发病率居各种肿瘤的第四位,在发展中国家则居第二位.在我国,胃癌死亡率在大、中城市从20世纪90年代的第一位降到第二位,但在城镇和农村仍高居首位.胃癌死亡率居高不下的主要原因之一是缺乏有效的早期诊断方法.纤维内镜检查可靠性强、准确率高,是目前胃癌临床诊断最有效的手段,但会造成一定的创伤和痛苦,患者在出现临床症状之前难似接受,所以使得大量亚临床期患者得不到及时诊断,从而错过了进行早期治疗的机会.我们从1997年开始进行胃癌早期诊断试剂的研制,先后对几十种配方进行了筛选,从中选出了效果较好的配方2LC,并于1999-08/2000-04进行了临床应用的研究,对172例
Gastric cancer is one of the common malignant tumors in the developed countries, the new incidence of all kinds of tumors ranks fourth in developing countries in second place in China, the mortality rate of gastric cancer in large cities in the 20th century The number one place in the 90s dropped to second place, but still tops in urban and rural areas. One of the major causes of the high gastric cancer death rate is the lack of an effective early diagnosis method. Fiber endoscopy has the advantages of high reliability and accuracy High, is the most effective means of clinical diagnosis of gastric cancer, but it will cause some trauma and pain, difficult to accept before the clinical symptoms, so that a large number of subclinical patients can not get timely diagnosis, which missed the early treatment Of the opportunity.We started from 1997 on the development of early diagnosis of gastric cancer reagents, has conducted dozens of formulations were screened from which to select the better effect of formula 2LC, and in 1999-08 / 2000-04 for clinical application The study, of 172 cases
