Diagnostic utility of conventional transbronchial needle aspiration in older patients

Background In older patients, diagnosis and initial treatment should be considered as soon as possible because of high disease burden and complications. Conventional transbronchial needle aspiration (C-TBNA) is an important and safe method for the diagnosis of mediastinal lesions and staging lung cancer in the general population. We aimed to evaluate the diagnostic utility and complications of C-TBNA procedure in older patients aged ≥ 65 years. Method We retrospectively evaluated C-TBNA results consecutively. Demographic data, clinical, radiological and flexible bronchoscopy (FB) findings, complications during C-TBNA and incidence of diagnostic C-TBNA with the presence of abundant lymphoid cells of polymorphous appearance both in patients aged ≥ 65 years and in younger patients were determined. Results C-TBNA was performed to a total of 317 patients, including 109 older and 208 younger patients attended to our clinic between 2012 and 2016. The mean ages of older and younger patients were 70.3 ± 4.6 and 52.5 ± 10 years, respectively ( p
