Abstract:Objective To evaluate the predictive effect of dynamic enhanced MSCT dynamic enhancement scan of hypotonic gastrography (DCE-CT) on preoperative TN staging of gastric cancer (GC).Methods A total of 68 GC patients who were admitted to Pingxiang People′s Hospital from February 2020 In August,2021 for surgical treatment were selected.All patients received DCE-CT exa mination of hypozhangxia stomach before surgery,and the surgical results of all patients were used as the gold standard for comparison.The gold standard results of all GC patients were observed and analyzed.The clinical efficacy of DCE-CT in diagnosing T staging in GC patients compared with the gold standard results was observed;clinical efficacy of DCE-CT in diagnosing N staging in GC patients compared with gold standard results was observed.Results Compared with the gold standard results,the accuracy,sensitivity and specificity of DCE-CT in diagnosing T1 staging in GC patients were 100.0%,66.7% and 100.0% respectively.The accuracy,sensitivity and specificity of T2 staging were 69.2%,90.0% and 84.0% respectively.The accuracy,sensitivity and specificity of T3 staging were 85.7%,80.0% and 90.9% respectively.The accuracy,sensitivity and specificity of T4 diagnosis were 80.0%,66.7% and 96.7% respectively.Compared with the gold standard results,the accuracy,sensitivity and specificity of DCE-CT in diagnosing N0 staging in GC patients were 72.7%,88.9% and 88.5% respectively.The accuracy,sensitivity and specificity of N1 staging were 63.6%,70.0% and 85.2% respectively.The accuracy,sensitivity and specificity of N2 staging were 75.0%,37.5% and 96.8% respectively.The accuracy,sensitivity and specificity of N3 staging were 87.5%,100.0% and 96.3% respectively.Conclusion DCE-CT examination of low-tensor stomach in GC patients can accurately predict and evaluate preoperative T and N staging,so as to provide better reference and basis for clinical diagnosis and treatment.
