STUDY OF GASTRIC CANCER INFILTRATION BY ENDOSCOPIC CARBON INK INJECTION

Abstract

For the accuracy of surgical resection, it is important to determine the extent of gastric cancer infiltration especially to oral side. In this study, biopsies were carried out at a distance of 2cm from the apparent infiltration border of the gastric cancer in 156 cases. Carbon ink was injected at this site. Malignant cells were found on the biopsy specimen in only one case. 31 cases were inoperative. Consequently, we studied 125 cases which were operated on for gastric cancer. Surgical resection was performed at a point past the carbon ink injection site. The relationship between the carbon ink injection site and the gastric cancer infiltration border was investigated on the resected specimens. In one case, the infiltration border of gastric cancer was found beyond the carbon ink injection site. The two cases cited above were diagnosed previously as Borrmann type IV gastric cancer, and histologically they were signet ring cell carcinoma.
