Utility of Cell-Block of Bronchial Washings in Diagnosis of Lung Cancer- A Comparative Analysis with Conventional Smear Cytology

摘要

IntroductionBronchoscopy is a safe & effective means of diagnosing bronchogenic carcinoma with a varying diagnostic yield of different bronchoscopic procedures.Cell-Block (CB) preparation of cytology specimen has been shown to increase the diagnostic yield further. To the authors’ knowledge, the diagnostic value of CB as an adjunct to conventional smear cytology (CS) of bronchial washing specimens in the detection of bronchogenic carcinoma has not been well evaluated.
