Roles of EBUS-TBNA in clinical practice

We read with interest the article published by Chung and colleagues entitled “Roles of EBUS-TBNA in non-small cell lung cancer” (1). The Authors reviewed their experience on 164 patients: 64 patients constituted the “diagnosis group” and EBUS –TBNA was used to establish the first diagnosis of non-small cell lung cancer biopsying mediastinal or hilar lymph-nodes; 100 patients represented the “staging group”, then EBUS-TBNA was used for staging or restaging mediastinal lymph-nodes. The sensitivity, specificity and accuracy reached by the Authors were of the highest quality, as a consequence there is no doubt that they managed this diagnostic method with great skill.
