Abstract

Gastric cancer is the most common gastrointestinal malignancy in Korea. Identification and evaluation ofgastric mass lesions and regional-distant metastases by abdominal CT scan are important for the treatment planningand prognostic implications of gastric cancer patients. Author reviewed CT scan are important for the treatemntplaning and prognostic implications of gastric cancer patients. Author reviewed CT scan of 61 cases of pathologyproven gastric cancer, retrospectively, for recent 20 months from July 1983 to Feb. 1985 at department ofradiology, Korea University, Hae Wha Hospital. The results were as follows: 1. There were 50 cases of advanced adenocarcinoma, 8 cases of early gastric cancer, 2 cases of leiomyosarcoma, and 1 case of lymphoma in total 61cases. 2. The sex ratio of male to female was 2:1. Age distribution was from 24 to 75 year old and peak incidencewas in 6th decade. 3. The most frequent site of involvement with gastric cancer was gastric antrum in 51%. 4. 48of the 50 patients with advanced gastric adenocarcinoma(96%) had a wall thickness greater than 1 cm, and all of 8cases of early gastric cancer had a wall thickness less than 1 cm. Regional lymph node tumor infiltration wasfound in 100% of gastric wall thickness greater than 2.0cm, in 64% of cases of 1.5 to 2.0cm, in 50% of cases of1.9 to 1.5cm, and 12.5% of cases of less than 1.0cm. 5. In a comparison of enlargement of reginal lymph node by CTscan to tumor infiltration of regional lymph node by histology, senitivity was 52%, specificity was 87%, and reliability was 66%. 6. The structures involved by distant metastases of these cases were the retroperitoneallymph node in 15, liver in 8, and pancrease in 3. 7. The diagnostic accuracy of CT staging was considered about68% by correlation of the surgical and histological findings. 8. The CT scan is one of the accurate and simpletool for evaluation of size, shape, extent, as well as distant metastases in the cases of gastric malignancies.
