I E Benign and malignant gastric ulcers: roentgen differentiation; an analysis of 142 cases proved histologically.

Abstract

It has long been considered that the differentiation of benign and malignant ulcerative gastric lesions is a problem to which the roentgenologist can make an important contribution, if not a decisive one. Recent improvements in technic make x-ray examination of the stomach more useful than ever before. On the other hand, the opinion has been expressed, occasionally in print and even more often verbally, especially by surgeons, that the radiologist's report is so frequently unreliable that it would be best to remove the ulcer at once, even though it appears benign roentgenographically, for fear of missing a malignant lesion. Quoted in support of this view are statements, often based on old clinical studies, that ulcerative lesions in certain locations, or of a certain size, are likely to be malignant, and that some lesions having the gross appearance of benign gastric ulcers showed carcinoma under the microscope. It seemed useful, therefore, to determine how often malignant gastric lesions were misdiagnose...
