Abstract

Objectives: The aim of this study is to describe imaging and assess the value of 64-slice CT in T staging of gastric cancer. Subjects and methods: From January 2021 to January 2022, 35 patients confirmed with gastric cancer by endoscopic biopsy underwent preoperative staging with 64-slice computed tomography followed by radical surgical treatment at 103 Military Hospital. Results: Tumors were found most commonly in antrum. The tumor size was 53.9 ± 19.3 mm in length and 17.3 ± 7.7 mm in thickness. The overall diagnostic accuracy of the T staging was 62.9%. The stage-specific sensitivity, specificity and accuracy for T staging of gastric cancers were Se 100%, Sp 96.5%, Acc 97.2% for T1, Se 25%, Sp 93.5%, Acc 85.6% for T2, Se 66.7%, Sp 68.9%, Acc 68.5% for T3, and Se 57.9%, Sp 93.8%, Acc 74.2% for T4. Conclusion: 64-slice CT is a useful modality in the T staging of gastric cancer.
