Abstract:
The purpose of this study was to evaluate the features of mediastinal lymph nodes in lung cancer patients during endoscopic ultrasonography(EUS), and to establish the clinical method for the preoperative staging of lung cancer using EUS. The EUS patterns of 103 lymph nodes in 21 patients with lung cancer were evaluated. Confirmation of benign and malignant lymph nodes was obtained by surgical resection and pathology. The following features were compared between benign and malignant lymph nodes: short axis , long axis, distinct margins and the shape of nodes. The results showed that all of the lymph nodes were hypoechoic. Both the short axis greater than 1.0cm and distinct margins or round shape independently predicted malignant invasion ( P
