贲门癌发病率不低,是我国某些地区高发肿瘤之一。但早期病例发现少,手术切除率低,疗效较食管癌差,临床也屡有误诊病例的报道。现状说明对贲门癌的认识尚不够深入。国内外在早期食管癌和早期胃癌的研究中做了大量工作,而早期贲门癌的研究仍处于初期阶段。一、早期贲门癌的病理特点可作为贲门癌的病例包括下段食管癌到上部胃癌,有下段食管贲门癌、食管胃接合部癌和食管胃境界领域癌等名称,其定 The incidence of cardiac cancer is not low, and it is one of the high-risk tumors in some areas of China. However, early cases were found with few surgical resection rates, the efficacy was worse than that of esophageal cancer, and clinical misdiagnosis cases were reported frequently. The status quo shows that there is not enough knowledge about cardiac cancer. At home and abroad, a lot of work has been done in the study of early esophageal cancer and early gastric cancer, and the study of early cardiac cancer is still in its infancy. First, the pathological features of early cardiac cancer can be used as a case of cardia cancer, including the lower esophageal cancer to the upper part of the stomach, there are lower esophageal and cardia cancer, esophageal stomach junction cancer and esophageal and gastric realm cancer, etc.
