 To improve diagnostic ability of the cancer of the cardioesophageal junction, 72 lesions of the cardioesophageal cancer diagnosed and resected last 15 years were analyzed on the macroscopic classification, size, dephth of invasion, and the radiological and endoscopic findings. Many of the lesions less than 3 cm in size were type IIc, whereas the lesions more than 3 cm in size were tend to be type 2, 3, 4 in macroscopic shape. The relationship between size and the depth of invasion were summarized as follows : the lesion less than 2 cm in size was may be limited in m invasion, the lesion two to three cm in size may have sm invasion and the lesion more than 3 cm in size may have ss or deeper invasion. Most of the lesions were the differentiated type of the histological classification. From the viewpoint of mucinous type classification, 28% of the entire lesion was the stomach type and 58% was the incomplete intestinal type, the lesion of both types less than 3 cm in size did not have prominent macroscopic changes.

 From the radiological diagnostic viewpoints, many lesions were detected as illdemarcated pale barium patches on the film exposed by the semi-standing, prone and first oblique position. Endoscopically, they were normal or brownish colored mucosa detected by down and turn-over views.
