Several clinical groups consider cytological assessment under EBUS (Endobronchial Ultrasonography)‐ROSE (Rapid Onsite Evaluation) as the golden standard for diagnosis and staging of intrathoracic lesions. On the other hand, some investigators proposed that EBUS‐TBNA (Transbronchial Needle Aspiration) has considerably high false‐negative rates for diagnosis. In this study, we analyzed our patient cohort (n = 152) with intrathoracic lesions and suspected malignancies evaluated by EBUS‐ROSE. Our specific aims were: (i) to determine whether EBUS‐ROSE could provide sufficient pathologic material for diagnosis and staging; (ii) to determine the fidelity of EBUS‐ROSE‐guided initial diagnoses in comparison to paraffin block diagnoses; (iii) to evaluate whether anatomical localization of sampled lymph nodes associate with material adequacy and final diagnoses.
