第四章早期胃癌、胃上皮异型增生、息肉及恶性淋巴瘤由于纤维光学仪器的广泛应用,早期胃癌的诊断现巳习以为常。它们表现为特定的大体形态。但是,如以各亚型之间的特性或对治疗反应的重要差别来检验日本胃肠内窥镜协会所提出的过细分类,看来还有疑问。该一分类以癌组织是否隆起粘膜表面和是否有溃疡形成为基础。它主要的实用意义似乎在于内窥镜学家之间对内窥镜形态所见的准确表达。不过,如果它给欲成为内窥镜专家们提供对那些尚可治愈的胃癌各种大体形态的注意,倒有更大
Chapter IV Early gastric cancer, gastric dysplasia, polyps and malignant lymphoma Due to the extensive use of fiber optics, the diagnosis of early gastric cancer is now common practice. They behave in a specific general form. However, there seems to be some question as to whether the subtle classification proposed by the Japanese Society of Gastrointestinal Endoscopy should be examined on the basis of characteristics between subtypes or important differences in treatment response. This classification is based on whether cancerous tissue bumps the mucosal surface and whether there is ulceration. Its main practical significance seems to be the accurate expression of the endoscopic morphology seen by endoscopists. However, it would have been larger if it was intended to provide the endoscopist with the attention to the various general forms of those still-curable gastric cancers
