The diagnostic value of cell block as an adjunct to liquid‐based cytology of bronchial washing specimens in the diagnosis and subclassification of pulmonary neoplasms

Abstract

CB combined with LBC was found to improve the rate of detection of malignancy over LBC alone, especially in cases with suspicious or atypical LBC diagnoses. Increased diagnostic yield is observed when CB is used with or without ancillary studies, but the yield is higher with CB using ancillary studies. CB serves as yet another available source of diagnostic material for immunohistochemical and molecular studies.
