Abstract

Objectives: To evaluate the accuracy of multiple detector computed tomography 128 slice in the preoperative staging of gastric cancer, prospectively comparing MDCT findings with pathological findings post-surgery. Subjects and methods: A cross-sectional descriptive study was compared with surgery and histopathology of 186 patients at Phu Tho General Hospital. The imaging results were performed by two experienced diagnostic radiologists, they do not know the results of histopathology. Results: MDCT has correct T staging rate of 81.7% compared to pathology. Accuracy in T staging was high for all T-stages, ranging from 91.39% to 98.92%. T1a, T1b staging have low sensitivity (50% and 31.75%), but high specificity (92.47% and 91.39%). T2 and T3 staging has relatively uniform sensitivity and specificity, 85.71% and 95.38% in T2 staging, 92.68% and 90.38% in T3 staging, respectively. The sensitivity in T4a and T4b staging were 75% and 80%, while the specificity were high, 98.27% and 100%, respectively. Conclusion: MDCT is the first choice for preoperative evaluation of gastric cancer, especially with high accuracy in T staging.
