Abstract
Background: The ratio of early to advanced gastric carcinomas in the cardiac region is significantly low. It is necessary to establish methods of early diagnosis of gastric carcinomas in the cardiac region. Methods: Twenty cases (21 lesions) of early gastric carcinomas in the cardiac region were resected between 1997 and 2001. We studied the macroscopic characteristics of the specimens, films of double-contrast upper gastrointestinal studies before operations, and the detectabilities of findings in each projection. Results: Four of 21 early gastric carcinomas in the cardiac region were on the anterior wall, 10 were on the lesser curvature, and seven were on the posterior wall. In seven of 21 lesions the carcinomas were not detected in the resected specimens macroscopically; in five, the area of carcinoma was not clearly traced in the resected specimens; and in nine, the area of carcinomas was clearly traced. In the morphologic study, 16 (76.2%), two (9.5%), two (9.5%), and one (4.8%) of the 21 lesions showed the superficial depressed type (IIc), superficial elevated type (IIa), superficial elevated and superficial depressed type (IIa + IIc), flat and superficial depressed type (IIb + IIc), respectively. Mucosal reddening was seen in 11, and mucosal discoloration was seen in one; change of color was not seen in the remaining nine lesions. Twenty lesions were diagnosed as differentiated adenocarcinomas, and one lesion was diagnosed as undifferentiated adenocarcinoma. Radiologically, early gastric carcinomas in the cardiac region had the following features: localized shallow barium deposits, localized abnormal barium coating, and niche and radiolucent lesions. Four (100%) of four lesions on the anterior wall, 10 (100%) of 10 lesions on the lesser curvature, and seven (100%) of seven lesions on the posterior wall were detected in the half-standing, prone, right anterior, oblique projection. Seven (100%) of seven lesions on the posterior wall and 10 (100%) of 10 lesions on the lesser curvature were detected in the half-standing, supine, left anterior, oblique projection. Conclusion: Even though most early gastric carcinomas in the cardiac region demonstrate few macroscopic findings, the half-standing, prone, right anterior, oblique projection and the half-standing, supine, left anterior, oblique projection are useful in the double-contrast studies.
