ENDOSCOPIC EVALUATION OF THE DEPTH OF INVASION OF THE DEPRESSED TYPE EARLY GASTRIC-CANCER AND APPARENTLY EARLY ADVANCED CANCER IN CASES OF A PEPTIC-ULCER WITHIN THE CANCER LESION
H. Isozaki et al., ENDOSCOPIC EVALUATION OF THE DEPTH OF INVASION OF THE DEPRESSED TYPE EARLY GASTRIC-CANCER AND APPARENTLY EARLY ADVANCED CANCER IN CASES OF A PEPTIC-ULCER WITHIN THE CANCER LESION, Gastroenterologia Japonica, 28(2), 1993, pp. 201-208
Depressed-type early and apparently early advanced cancers were divide
d into two groups according to whether or not an associated peptic ulc
er was present within the cancer lesion, and the accuracy of preoperat
ive endoscopic diagnosis was reviewed. As a result it was found that e
valuation of depth of invasion was more difficult in the ulcer [UL(+)]
group than in the group without an ulcer [UL(-)]. In the UL(+) group
it was difficult to identify endoscopic findings which indicate depth
of invasion at the tip of the folds, the volume of cancer invasion of
the deeper layers was small, and there were many cases of invasion of
deeper layers in a portion of the margins of the peptic ulcers.
