[Evaluation of CT scan for carcinoma of the gastric cardia].

CT scans of 50 cases with carcinoma of gastric cardia were analyzed. 45 cases were operated but 12 were explored only. The causes of unresectability were: bulky primary tumor, regional lymph node involvement, infiltration of the adjacent structures, e.g. liver, pancreas, spleen and diaphragm, intragastric extension and ascites. By CT scan, the detection rate of the visceral organ involvement was: diaphragm 4/7, pancreas 3/10, liver 4/6 and spleen 5/6. Therefore, it is very important to have a preoperative CT scan for carcinoma of gastric cardia.
