Abstract

Gastric cancer is the most common gastrointestinal tract malignancy in Korea. When the patient has been detected, these tumors are usually advanced. CT is important for planning of treatment, assesssing surgical resectability, postoperative evaluation and prognosis. Author reviewed CT scan of 78 cases of confirmed gastric cancer by UGI series and endoscopic biopsy, for 14 months from May 1988 to June 1989 at Department of Diagnostic Radiology, Taegu Fatima Hospital. The results were as follows; 1. Male to female ratio was 1.6:1 and the peak age groups are 6th decade and 7th decade. 2. The most frequent site of involvement was gastric antrum in 44.9%(35/78),antrum and body in 23.1%(18/78) in the order. 3. The reliability of pancreatic involvement was 88.2%(45/51). 4. The diagnostic accuracy of CT staging was 66.7%(34/51) by correlation of surgical and pathological findings. 5. The most common cause of non-operation was 17 cases(60.3%) of stage IV, old age, operation refusal in the order. 6. The accuracy of regional lymph node involvement between CT and pathologic finding was 62.7%(32/51).
