日本胃肠镜协会制定早期胃癌限于侵犯胃粘膜层和粘膜下层。分三型:Ⅰ型—隆起型、Ⅱ型—平坦型、Ⅲ型—凹陷型。Ⅱ型又分Ⅱa(隆起)、Ⅱb(平坦)、Ⅱc(凹陷)。早期胃癌切除后,预后良好,五年生存率达85～90％。在日本和德国,因选择高危险因素病人和改善诊断方法,提高了早期胃癌的发现率。高危险因素:①胃癌家族史;②恶性贫血;③巨大肥厚性胃炎;④胃切除术后(大约十五年);⑤胃息肉;⑥胃溃疡。所有诊断方法中,纤维胃镜和直视下活组织检查是首选的,因操作简便、安全,对怀疑病
The Japanese Society of Gastrointestinal Mirrors has defined early gastric cancer as invading the gastric mucosa and submucosa. Divided into three types: type I - uplift type, type II - flat type, type III - depression type. Type II is divided into IIa (uplift), IIb (flat), IIc (depression). After the resection of early gastric cancer, the prognosis is good, and the 5-year survival rate is 85-90%. In Japan and Germany, the rate of discovery of early-stage gastric cancer has increased due to the selection of high-risk patients and improved diagnostic methods. High risk factors: 1 family history of gastric cancer; 2 pernicious anemia; 3 huge hypertrophic gastritis; 4 after gastrectomy (about 15 years); 5 gastric polyps; 6 gastric ulcers. Among all diagnostic methods, fiberoptic gastroscopy and biopsy under direct vision are preferred because of ease of operation, safety, and suspicion of disease
