Value of C-ROSE During EBUS-TBNA to Obtain the Tissue Sample in the Diagnosis of Lung Cancer / 中国肺癌杂志

ABSTRACT

BACKGROUND@#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<0.05), the incidence of complications in the C-ROSE group was signicantly lower than that in the No C-ROSE group (1.23% vs 11.67%, P<0.05). The sensitivity, specificity, positive predictive value and negative predictive value of C-ROSE combined with EBUS-TBNA in the diagnosis of lung cancer are 92.21%, 100.00%, 100.00% and 40.00%.@*CONCLUSIONS@#EBUS-TBNA combined with C-ROSE can improve the specimen qualified rate and diagnostic rate, also can reduce the complications thus worthy of further promotion.
