THE ANALYSIS OF TUMOR GROWTH PATTERN BY ENDOSCOPIC ULTRASONOGRAPHY IN THE PATIENTS WITH DEPRESSED TYPE OF GASTRIC CANCER

Abstract

The growth pattern in the gastric wall of the thirty-five patients with the depressed type of gastric cancer including Borrmann type of advanced cancer was analysed by endoscopic ultrasonography.
It was demonstrated that the gastric wall infiltrated by the tumor was significantly thickened by the accompaning with ulceration or the progression of the disease as compared with that of IIc type of gastric cancer without ulceration.
The growth pattern in the gastric wall was clearly distinguished each other by the difference of macroscopical appearance of the gastric cancer; IIc type of gastric cancer with ulceration and Borrmann 2 type of gastric cancer showed the inward growth only, while IIc-like advanced gastric cancer and Borrmann 3 type of gastric cancer showed both inward and outward growth.
By these observation of the growth pattern, it may be possible that the more accurate diagnosis of the depth of cancerous invasion by endoscopic ultrasonography can be made in the patients with depressed type of gastric cancer.
