|
Gastric cancer is the most common G-I malignancy in Korea. Preop. CT staging by the evaluation of gastric mass lesion and regional-distant metastases are important for the therapeutic planning, surgical and prognostic implication of patients.
Author
reviewed CT scan of 48 cases of postop. Pathologic proven gastric cancer retrospectively from Aug. 1990 to Dec. 1991 at department of radiology, Seoul Red Cross Hospital.
@ES The results are as follows:
@EN 1) Most frequent site of involvement with cancer was gastric antrum in 44%, combined body and antrum in 25%.
2) 38 of the 48 cases with AGC(79%) had a wall thickening greater than 1.0 cm, and definite relationship of marked wall thickening(greater than 1.5cm) with omental invasion.(18 of 23 cases: 78%)
3) CT detection of L-node metastasis is 63%, distant metastasis is 46.7%.
4) Diagnostic accuracy of CT staging was considered about 44% by correlation of surgicohistologic finding.
5) The CT scan is the accurate, noninvasive, reliable diagnostic method for evaluation of preop. Staging of gastric cancer. For the more increased accuracy of CT staging, careful, detailed reading afford of radiologist are necessary.
