Abstract:
Objective:To explore the application value of endoscopic ultrasonography (EUS) on preoperative diagnosis and clinical staging of esophageal cancer.Methods: In accordance with the international federation of tumor cancer alliance (UICC) and the United States (AJCC) (2003) TNM staging criteria, 45 cases of esophageal cancer patients confirmed by biopsy and gastroscope examination did preoperative diagnosis and clinical staging with EUS, and the results were compared with postoperative pathological staging results.Results: Fourty-five patients had esophageal EUS imaging characteristics, EUS on 45 cases of esophageal cancer patients with preoperative diagnostic accuracy rate was 100.0%; Clinical staging based on the result of postoperative histopathologic examination, preoperative EUS for esophageal T staging overall diagnostic accuracy was 82.2%, T1, T2, T3, T4 diagnostic accuracy respectively was 85.7%, 83.3%, 82.4% and 85.7%; The overall diagnostic accuracy was 77.8% for N staging, N0 and N1 stage diagnostic accuracy respectively was 80.0%, 76.0%.Conclusion: Accuracy rate of EUS on preoperative diagnosis of esophageal cancer is higher, accuracy rate of EUS on preoperative T and N staging of esophageal cancer is also high, it can be important basis of esophageal preoperative treatment selection and prognostic evaluation, and has higher clinical value.
