EBUS Score Validation for Malignancy

Patients undergoing EBUS with TransBronchial Needle Aspiration will be invited to enroll on the day of their procedure. Once informed consent is obtained, the surgeon will assess the sonographic criteria, take pictures, and biopsy every lymph node of interest. All three elements of this assessment will need to be completed for a specimen to be included in the study. After the procedure, the operating surgeon will fill the Lymph Node Assessment questionnaire, assign an aggregate score to every lymph node specimen, and attach the pictures to the form. Pictures from every specimen will stored electronically to be reviewed and secondarily rated by a second blinded surgeon. Patient involvement in the study ends at the completion of the planned procedure.
