Abstract:Objective To analyze the diagnostic value of multi-slice spiral CT combined with serum vascular endothelial growth factor (VEGF) and B cell lymphocyte 2 (Bcl-2) levels in esophageal cancer.Methods A total of 100 patients with suspected esophageal cancer admitted to General Hospital of Tianjin Medical University from October 2019 to December 2020 were selected as the research subjects. All patients received MSCT examination, and VEGF and Bcl-2 levels was recorded before operation. With the surgical diagnosis result as the "gold standard", the sensitivity, specificity, and accuracy of the combined diagnosis of esophageal cancer by MSCT, VEGF and Bcl-2 levels were analyzed, and the levels of VEGF and Bcl-2 in patients with different clinical symptoms of esophageal cancer were compared.Results Among the 100 suspected cases, 86 were diagnosed as esophageal cancer by surgery, and the remaining 14 patients were benign lesions; the levels of VEGF and Bcl-2 in the malignant group were higher than those in the benign group (P < 0.05); the sensitivity of MSCT, VEGF, Bcl-2, and combined diagnosis of esophageal cancer was respectively 84.88% (95% CI: 0.698, 0.928), 81.40% (95% CI: 0.673, 0.904), 79.07% (95% CI: 0.684, 0.899), 94.19% (95% CI: 0.885,0.996), and the specificity was respectively 71.43% (95% CI: 0.584, 0.857), 64.29% (95% CI: 0.463, 0.689), 57.14% (95% CI: 0.440, 0.651), 78.57% (95% CI: 0.648,0.873), and the accuracy was respectively 83.00% (95% CI: 0.685, 0.912), 79.00% (95% CI: 0.663, 0.895), 76.00% (95% CI: 0.674, 0.886), 92.00% (95% CI: 0.835, 0.985); there was no significant difference in the levels of VEGF and Bcl-2 in patients with different lesion locations and pathological types (P > 0.05); The levels of VEGF and Bcl-2 in patients with different TNM stages, degree of differentiation, tumor diameter, and lymph node metastasis had significance (P < 0.05).Conclusion MSCT combined with VEGF, BCL-2 level detection has a certain guiding significance in the diagnosis of esophageal cancer, help to improve the diagnostic sensitivity and accuracy.
