Abstract:
PURPOSE: We evaluated the role of conventional CT for preoperative staging of gastric carcinoma. MATERIALS AND METHODS: Conventional CT was prospectively performed in 95 patients with gastric adenocarcinoma proved by means of endoscopic biopsy, and findings were compared with those of surgery or pathology. RESULTS: In the evaluation of pancreatic invasion of the primary tumor, the sensitivity, specificity, and diagnostic accuracy of CT were 71%(5/7), 95%(84/88), and 94%(89/95), respectively. CT depicted transverse mesocolon invasion in only one of the 4 cases(25%). In the evaluation of lymph node metastasis, the sensitivity, specificity, and diagnostic accuracy were 33%(24/72), 99%(867/878), and 94%(891/950), respectively. In lymph node staging, 49 patients(52%) were correctly staged, 39(41%) were understaged, and 7(7%) were overstaged with CT. CT failed to demdnstrate peritoneal carcinomatosis in all 10 patients. CONCLUSION: The role of conventional CT in the preoperative evaluation of gastric adenocarcinoma is limited due to poor sensitivity despite of good specificity and accuracy.
