EBUS-TBNA-RTE VS Radiography in Staging of NSCLC

Overview

The purpose of this study is to make a qualitative and quantitative analysis of the intrathoracic lymph nodes by CP-EBUS elastography for the first time, and to make a benign and malignant diagnosis.

The newly developed convex array can be used to identify the hardness of the lymph nodes and estimate the benign and malignant lymph nodes indirectly through the quantitative and visualized analysis of the elastic coefficient of the bronchus through the CP-EBUS elastography mode. The purpose of this study is to make a qualitative and quantitative analysis of the intrathoracic lymph nodes by CP-EBUS elastography for the first time, and to make a benign and malignant diagnosis. 120cases will be enrolled.Compared with the commonly used methods to evaluate intrathoracic lymph node metastasis, the accuracy of chest CT and PET-CT were compared. The lymph node staging method and the final pathological gold standard of the three groups were compared, so as to verify the accuracy and clinical popularization of the bronchial ultrasound elastography mode.
