So called early cancer was 4. 5%. 4) In gastric ulcer, the site of lesion revealed that the antrum was the highest frequency (43. 3%), the next was angle (33. 3%), and the body (23. 7%) in order, while in gastric cancer, a e antrum was 40. 7%, the body was 32. 1% and the angle was 27. 2%, 5) In relationship between radiologic and endoscopic findings equality was noted in 79, 3% of gastritis, in 89. 5% of gastric ulcer and in 98. 7%of gastric cancer. 6) Of the total 2470 cases, 1303 cases were associated with other diseases, as follows; liver diseases(24. 7%), anemia(16. 2%), helminthiasis(14%), neurosis(6.
