Abstract:
Objective To compare T and N staging of esophageal and cardia cancer by endoscopic ultrasonography (EUS) and computed tomography (CT) before operation, and to evaluate clinical value of EUS.Methods Twenty-eight patients received examination of EUS and CT preoperatively, and the T and N staging was determined. The accuracy rates of both T, N staging were compared by the postoperative pathological results, at the same time, the accuracy rates of lymph node metastasis were compared, and the value of application of EUS was investigated. Results In the twenty-eight cases, the accuracy rates of EUS were higher than that of CT by 89.3% ( 25/28 ) to 46.4% ( 13/28 ) in T staging. And the difference had statistical significance( P = 0. 004 ,P ＜ 0.01 ). The N stagings of both were 82.1% (23/28) and 50.0% ( 14/28), and the difference had statistical significance ( P = 0. 035, P ＜ 0. 05 ). The accuracy rates of lymph node metastasis of both were 88.7% and 72.2% respectively, and the difference had statistical significance (χ2 = 7.031,P = 0.008, P ＜ 0. 01 ). Conclusions EUS has very important value in preoperative staging for esophageal cancer and cardia cancer, and the T staging of EUS is better than that of CT. The short axis and the ratio of short to long axis (S/L) combined with the lymph node ultrasonography image can improve the accuracy rates of lymph node metatsasis and N staging.
