Abstract:
Objective To study preoperatively on TNM staging of esophageal carcinoma by endo-scopes ultrasonography ( EUS). Methods Sixty-one patients with esophageal carcinoma were preoperatively staged by EUS. The results were compared with the postoperative histopathological staging according to the new (1997) TNM classification. Results Clinical staging of T subsets by EUS was reliable with an overall accuracy rate of 86. 9% , while that of N subsets was relatively more difficult with an overall accuracy rate of 52. 5% ; sensitivity and specificity of regional lymph nodal metastases were 88. 9% and 23. 5% respectively. Conclusion EUS is relatively an accurate measure in assessing the depth of tumor infiltration, whereas further efforts are needed to improve the accuracy in N staging. EUS will be helpful in choice of the appropriate therapeutic procedure and predicting the possibility of surgical resection.
