THE DIAGNOSIS OF THE DEPTH OF CANCER CELL INFILTRATION IN ADVANCED CANCER SIMILAR TO EARLY CANCER

-MAINLY, DEPRESSED TYPES-

Abstract

The 41 cases of advanced cancer were examined which was similar types to early gastric cancer from standpoint of the depth of cancer cell infiltration mainly by means of X-ray and endoscopy. These cases were experienced in our clinic, from 1967 to 1977. The following results were obtained. 1) The 92. 7 per cent of similar types to early gastric cancer were depressed type such as IIc, IIc+III and III+IIc type. 2) Most cases of mis-diagnosis consisted of small lesions which were between 1 and 2cm in the geatest diameter, of wedge-shaped cancerous infiltration, pm cancer, and with ulcer or ulcer scar. 3) When we diagnosed the depth of cancer infiltration, we should estimate the existence of following various characteristic features which were helpful for the estimation of the depth of malignant involvement, and sm invasion. That is, these characteristic features were consist of finding at the margin of convergent fold, depth of depression, stiffness around depression, surrounding transluency on the compression image, and so on. When diagnosis of the depth of cancer infiltration was done by them synthetically, the rate for accurate diagnosis of depth of cancer infiltration increased up to 71 per cent. 4) The prognosis of similar types to early gastric cancer was good, and five years survival rate was 85 per cent.
