Abstract:
Objective To compare the performances of endoscopic ultrasonography (EUS) and multislice spiral computed tomography (MSCT) in the preoperative staging of Borrmann type Ⅳ gastric cancer. Methods 48 patients involved in this study, all the patients had undergone surgical resection, Borrmann Type Ⅳ gastric cancer had con-firmed and evaluated by EUS and MSCT. Tumor staging was evaluated by Tumor-Node-Metastasis (TNM) staging. The results from the imaging modalities were compared with postoperative histopathological outcomes. Results The overall accuracies of EUS and MSCT for the T staging category were 54.2 % and 79.2 %( = 0.009), respectively. Stratified analysis revealed that the accuracy of MSCT in T3 and T4 staging was significantly higher than that of EUS ( = 0.032 for both). The overall accuracies of EUS and MSCT for the N staging category were both 56.3%. The sensitivity and specificity of EUS and MSCT in N staging were 83.3 %/72.2 % and 66.7 %/91.7 %, respectively. Conclusion MSCT prevail over EUS for Borrmann Type Ⅳ gastric cancer patients with invasion into serosal layer or adjacent organs or with distant metastasis.
