ABSTRACT
Objective@#To investigate the clinical value of endoscopic ultrasonography (EUS) and Multi-slice Spiral CT (MSCT) in the preoperativestaging of tumor(T) and lymph node (N) metastasis in patients with SiewertⅡand Ⅲ typeadenocarcinoma of esophagogastric junction(AEG).@*Methods@#Clinical data of 145 Siewert Ⅱ and Ⅲ type AEG patientswithout preoperative chemoradiotherapy were retrospectively reviewed. Theyall received preoperative EUS and MSCT examination and underwent surgical resection, and the results of EUS and MSCT were compared with their postoperative pathologic staging.@*Results@#The sensitivity, specificity, and accuracy of EUS for T stage in Siewert Ⅱ and Ⅲ type AEG were higher than those of MSCT. The total accuracy of EUS and MSCT were 90.3% and 63.5%, respectively, and the difference was statistically significant (χ2=29.52, P<0.01). The sensitivity of EUS for T1, T2 and T3 were 89.5%, 91.1% and 85.2%, respectively, which were significantly higher than 42.1%, 66.7% and 29.6% of MSCT (χ2=9.47, P<0.01 for T1; χ2=8.07, P<0.01 for T2; χ2=17.40, P<0.01 for T3). In addition, the total accuracy of EUS and MSCT for lymph node metastasis status of Siewert Ⅱ and Ⅲ type AEG were 75.9% and 64.8%, respectively, showing a statistically significant difference(χ2=4.23, P=0.04). The sensitivity of EUS for N1 and N2 were 82.1% and 79.2%, respectively, which were significantly higher than 53.6% and 60.4% of MSCT (χ2=5.24, P=0.02; χ2=4.48, P=0.03). There was no statistical significance for sensitivity of EUS and MSCT in N0 and N3 (P>0.05).@*Conclusion@#EUS diagnosis of T and N staging in Siewert Ⅱ/Ⅲ type AEG showed significantly greater performance than MSCT.
