Value of C-ROSE During EBUS-TBNA to Obtain the Tissue Sample 
in the Diagnosis of Lung Cancer

Background and objective Most of the patients with lung and (or) mediastinal occupying lesions are considered to be primary lung cancer clinically, and endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a commonly useful operation to obtain the tissue sample and get definitive diagnosis of pathological tissues. In the EBUS-TBNA process, cytological rapid on-site evaluation (C-ROSE) is a useful technology. The purpose of our study is to discuss the value of C-ROSE in the diagnosis of lung cancer by EBUS-TBNA sampling. Methods Retrospective analysis of 141 cases clinical data who were performed with EBUS-TBNA and suspected diagnosis primary lung cancer, which were found have mediastinal and (or) lung lesions (including the enlargement of the lymph nodes/mass) by computed tomography (CT). Among these patients, 81 patients were in the C-ROSE group and 60 patients were in the No C-ROSE group. The message of puncture and complication of EBUS-TBNA with or without C-ROSE were compared. At the same time, we analysis the sensitivity and specificity, positive predictive value, negative predictive value of C-ROSE combined with EBUS-TBNA in that of the diagnosis of lung cancer. Results We found no statistical difference of the needle passes between C-ROSE group and No C-ROSE group. But in C-ROSE group, specimen qualified rate and diagnostic yields were signicantly higher than No C-ROSE group (98.77% vs 90.00%, 88.89% vs 75.00%, P
