performed in each station, and immunohistochemistry was made in cellblocks as well as DNA extraction for EGFR mutation studies and EML4/ALK gene rearrangements in 50% of cases of NSCLC and PDL1 in 19,2% of these cases. 10(9,26%) of the series was taken to mediastinoscopy with a 100% correlation with the results of EBUS-TBNA. Conclusion: EBUS-TBNA is the recommended technique for lung cancer mediastinal staging. Our results adjust to international results; it is safe, minimally invasive, in many cases an outpatient procedure and a good performance when accompanied with ROSE.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
