Abstract
AIM:To explore the accuracy of spiral computed tomography in the staging of gastric cancer, and to provide clinical guide for the treatment and prognosis analysis.
METHODS:Forty-five patients with gastric cancer received TNM staging by spiral computed tomography before operation. The results were comparatively analyzed with the surgical pathology.
RESULTS:The accuracy of SCT for T stage, N stage and M stage and total TNM staging were 75.6%, 73.3%, 86.7%, and 75.6%, respectively. If the attenuation values of more than or equal to 25 Hu in plain scan, or 70 Hu in arterial phase, or 80 Hu in venous phase were used as a criterion to detect the metastasis-positive lymph nodes, the sensitivity and specificity were 98.4% and 64.0%, respectively.
CONCLUSION: Spiral computed tomography is accurate in the preoperative TNM staging for gastric cancer.
Key Words: Gastric cancer; Spiral computed tomography; TNM staging; Lymphadenopathy
