Abstract
Objective: To study the value of using oral contrast ultrasonography(OCU), multislice computed tomography(MSCT), and the combination of the two methods in diagnosing gastric cancer. Methods: Sixty cases of gastric cancer confirmed by endoscopic biopsies and surgeries were examined by OCU and MSCT before surgery. Imaging TNM staging and postoperative pathology were compared. Results: For the total accuracy of T staging, OCU was 80.00%(48/60), MSCT was 71.67%(43/60), and their combination was 88.33%(53/60). The difference of these three methods for T staging was not statistically significant(P>0.05). However, for T1 and T2 staging, OCU(62.50%, 77.78%) was more accurate than MSCT(37.50%, 55.56%). For the total accuracy of N staging, OCU was 61.67%(37/60), MSCT was 73.33%(44/60), and their combination was 85.00%(51/60). The difference of these three methods for N staging was statistically significant(P<0.05). For the accuracy of N3 staging, OCU was 35.00%(7/20), MSCT was 75.00%(15/20), and their difference was statistically significant(P<0.05). There was no significant difference among OCU, MSCT and their combination for M staging. Conclusions: The combination of OCU and MSCT can improve the accuracy of TNM staging for gastric cancer, and have important reference value for designing surgery or treatment programs.
