贲门癌是我国胃癌发生比较多的部位,但到目前早期贲门癌的发现较少,临床、X线误诊率很高,发现时多为中晚期病例,手术切除率低,治疗效果差。 近年来由于内窥镜和X线检查技术的进步,国内外对早期胃癌的研究已取得很大进展,而对早期贲门癌的研究,仍处于初期阶段。现状说明我们对早期贲门癌的研究和认 Cardiac cancer is the most common site of gastric cancer in China. However, the current detection of cardiac cancer is relatively rare. The rate of clinical and X-ray misdiagnosis is very high. Most of the cases are found in late-stage patients. The surgical resection rate is low and the treatment effect is poor. In recent years, advances in endoscopy and X-ray examination technology have made great progress in the study of early gastric cancer at home and abroad, and the study of early cardia cancer is still in its infancy. The status quo explains our research and recognition of early cardiac cancer.
