目前多数学者认为胃癌癌前疾病(或状态)包括慢性萎缩性胃炎(CAG),冒息肉,肥厚性胃炎,残胃,恶性贫血,胃溃疡;胃癌癌前病变包括胃粘膜异型增生,肠化生。胃癌高危人群即指患有上述疾病或病变的人群。现国内外经验认为在高危人群中进行普查与随访是发现早期胃癌的最有效方法。为了进一步在高危人群中寻找癌变规律,缩小随访范围,我们选其中常见的CAG,残胃,胃息肉,胃溃疡(GU),及伴异型增生和肠化生病变的活检胃粘膜组织,应用胃癌单克隆抗体MG_7,进行ABC免疫酶标组化染色,观察MG_7的相应抗原
At present, most scholars believe that precancerous conditions (or conditions) of gastric cancer include chronic atrophic gastritis (CAG), polyposis, hypertrophic gastritis, residual stomach, pernicious anemia, and gastric ulcer; gastric precancerous lesions include gastric dysplasia, intestinal metaplasia . High-risk populations of gastric cancer refer to people suffering from the above-mentioned diseases or diseases. At home and abroad, it is believed that conducting surveys and follow-ups in high-risk populations is the most effective method for detecting early gastric cancer. In order to further search for cancerous changes and narrow the follow-up range in high-risk groups, we selected common CAG, residual stomach, gastric polyps, gastric ulcer (GU), and biopsy gastric mucosa with dysplasia and intestinal metaplasia. Monoclonal antibody MG_7 was stained with ABC immunohistochemistry to observe the corresponding antigen of MG_7
