Comparative study of bronchial brushing and transbronchial needle aspiration cytology in diagnosing lung cancer

Aim: To compare sensitivity, specificity and accuracy of bronchial brushing (BB) and transbronchial needle aspiration (TBNA) cytology in diagnosing lung cancer and to correlate and compare them with corresponding histopathology. Introduction: Lung cancer is a leading cause of death worldwide in both genders. Various cytological techniques such as BB and aspirate, TBNA, bronchoalveolar lavage, transthoracic and pleural puncture can aid in early diagnosis of lung malignancies. Material and Methods: One-year retrospective study included 359 patients with suspected lung cancer who underwent bronchoscopy. During bronchoscopy, cytopathological samples were obtained for smears using BB and TBNA as well as biopsy for histopathological examination that was considered the  gold standard .  All the samples were microscopically examined and statistically analyzed using descriptive methods and non-parametric Kendal-tau correlation coefficient (the level of significance p<0.05). Results: Sensitivity of BB and TBNA cytology comparing to histopathology was 97.17% and 98.32% respectively whereas specificity was 97.26% and 97.75 % respectively. Positive predictive value was 97.14% in BB and 99.66% in TBNA and negative predictive value was 93.23% in BB and 98.77% in TBNA. The accuracy of BB was 96.51% and 99.14% of TBNA cytology. Discordance of BB cytological and histopathological diagnosis was in 3.21%, whereas discordance of TBNA was in 2.03% cases. There was no statistically significant difference neither between BB (p=0.550) nor between TBNA (p=0.602) cytology and histopathological diagnosis. Conclusion: Cytology is valuable and useful in establishing lung cancer diagnosis, which yields almost the same information as histopathology no matter which method of cytological sampling is used.
