|Keywords||endoscopic ultrasonography esophageal cancer diagnosis preoperative clinical staging|
Objective:To evaluate the guidance value of EUS in preoperative clinical staging for diagnosis and treatment of esophageal cancer. Methods:58 patients with esophageal cancer were examined preoperatively by EUS, and staged according to the new TNM staging system(2003). The EUS findings were compared with surgical pathologic findings. Results:The accuracy rates of T staging by EUS were71.4% for Tl,71.4 % for T2,80.0% for T3,66.7% for T4, and 81.5% for T; those of N staging were 80.8 % for NO,63.6% for N1, and 70.7% for N. Conclusion:The accuracy rates of EUS are higher for diagnosis in esophageal cancer and preoperative staging. There is great significance for choosing ideal therapy plan for esophageal cancer, and for estimating prognosis of esophageal cancer.
