This is a prospective randomized clinical trial with the study cohort comprised of all male and female patients over the age of 21 presenting to the study site for evaluation of lung cancer. The study will enroll 300 subjects, with 150 in each arm. Three sites will be in the study, Mayo Rochester, Mayo Jacksonville and Medical University of South Carolina. Mayo Rochester will enroll approximately 125 subjects. This study does not require subjects to undergo any additional procedures than what they would receive per standard medical care. The consenting subjects will receive EUS and /or EBUS- guided FNA or Mediastinoscopy/Thoracoscopy.

Detailed Description:
This is a prospective randomized clinical trial of males and females age 21 or older being evaluated for lung cancer. The study will enroll approximately 300 subjects (150 in each arm) at 3 participating centers (MUSC, Mayo Clinic Rochester and Jacksonville). This sample size will provide sufficient statistical power (i.e. >80%) using a non-inferiority study design with 1-sided hypothesis testing (Farrington and Manning 1990) to determine whether or not the sensitivity of the EUS/EBUS diagnostic technique is inferior (i.e. 10% or more lower) when compared to the sensitivity of malignant mediastinal adenopathy of about 40%. This study requires subjects to agree to the selection of their standard of care procedure. Subjects will be randomized (stratified computer generated randomization stratified y center and y CT positivity for pathologically enlarged [>1cm short axis] node - 10 strata). Randomization will use variable block sizes (4-8), so that randomization allocation remains concealed as investigators will not be blinded. This study requires subjects to consent to the release of outcome data and follow-up data to be used for study analysis. No additional visit will be required for this study; this study will not require any additional time requirements beyond their scheduled evaluations.
