What is the yield of EBUS-TBNA for re-evaluation of previously treated non-small-cell lung cancer?

Background/aAim: Locoregional recurrence in lung cancer still remains an important problem. We aimed to indicate the effectiveness of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for reevaluation previously treated nonsmall cell (NSCLC). Materials and methods: NSCLC patients who underwent EBUS rebiopsy suspicious recurrent or progressive lesions between January 2010 June 2017 were reviewed. Patients categorized into two groups based on previous treatment modalities: Group 1 (G1) consisted had been with chemoradiotherapy, 2 (G2) undergone radical surgery. Results: Of 115 patients, 100 enrolled study. 26 35 lymph nodes G1, malignant cells identified thirteen (50%). Anthracosis was detected remaining. Malignancy 28 (37.8%) G2. Thirty-three diagnosed as benign (24 anthracosis; 8 lymphocytes, granulomatous); not sampled, inadequate material obtained five. The sensitivity, specificity, negative positive predictive value, overall diagnostic accuracy EBUS-TBNA G1 84.8%, 100%, 89.1%, 93.2%, respectively. These values all perfect Conclusion: could be preferred a feasible efficient procedure patients.
