本文报告一年内(1979、4—1980、3)收验的1000例次纤维胃镜活检标本病理组织学观察。讨论了各种胃疾病包括胃炎、息肉、溃疡及癌的发病率及形态学特点,重点讨论了胃粘膜肠上皮化生和不典型增生。发现肠上皮化生和不典型增生与胃癌的关系非常密切,因此将这些病变看作胃癌前期病变,尤其是肠上皮化生基础上的不典型增生更为明显。根据AB-PAS染色反应,胃癌的组织来源可以分为四型,即肠型、胃型、混合型和不能分型。
This article reports the histopathological observation of 1000 cases of fiber endoscopic biopsy specimens received within one year (1979, 4-1980, and 3). The incidence and morphological characteristics of various gastric diseases including gastritis, polyps, ulcers and carcinomas were discussed, with emphasis on intestinal metaplasia and atypical hyperplasia of the gastric mucosa. It was found that intestinal metaplasia and atypical hyperplasia are closely related to gastric cancer. Therefore, these lesions are regarded as precancerous lesions of gastric cancer, especially atypical hyperplasia based on intestinal metaplasia. According to the AB-PAS staining reaction, the tissue origin of gastric cancer can be divided into four types, namely, intestinal type, gastric type, mixed type, and non-typeable type.
