 The growth and extension of esophageal carcinoma was studied with special reference to x-ray findings.

 Of patients whose radiographic studies were done in from 5 to 26 months before the resection, or before a definite diagnosis was made at the Institute of Gastroenterology, Tokyo Women's Medical College, 13 cases had been suspected of having esophageal carcinoma by x-ray findings.

 Among six cases diagnosed as superficial flat and erosive depressed types on an intial x-ray examination, two cases developed into into the superficial elevated type, one case into a superficial depressed type and two cases into the serrated type while the remaining case was of the superficial flat type.

 Two cases were of the superficial protruded type at the initial x-ray examination, but developed into superficial depressed and serrated types characteristic of depressed lesions.

 Out of four cases of the superficial depressed type, three cases changed into the serrated type and one case remained as the same depressed type.

 When diagnosed by an x-ray finding based on “General rules for radiological studies on depth invasion”, it can be said that m-carcinoma changes into sm-carcinoma in seven to ten months. In general, sm-carcinoma does not invade beyond the submucosal layer within a six month period. It takes 6-26 months for sm-carcinoma to reach the adventitia.

 Generally speaking, the superficial flat type and the erosive depressed type, which usually spread superficially, seldom have either vessel invasion or lymph node metastasis.

 On the other hand, the ones with x-ray findings clearly showing deeply infiltrated carcinoma usually have lymph node metastasis.
