Bronchoscopic diagnosis of endoscopically visible lung malignancies: should cytologic examinations be performed routinely?
Aims: The aim of this study was to determine the diagnostic yield of flexible bronchoscopy in endoscopically visible malignancies and to evaluate whether cytological examination including bronchial washings and brushings increase the diagnostic yield compared with bronchial biopsy alone. Methods We reviewed a series of bronchoscopies over a period of 7.5 years in which an endoscopically visible tumour was identified and which had a definite cytological or histological diagnosis of pulmonary malignancy obtained by bronchoscopy or any other examination. Results The above criteria were met by 174 bronchoscopies. ⋯ Conclusions The tumour detection rate with flexible bronchoscopy in endoscopically visible lung malignancies is high. Cytology-based sampling techniques by means of bronchial washings and brushings significantly increase the overall diagnostic yield compared to forceps biopsy only. Repeat bronchoscopies after an initial non-diagnostic bronchoscopy have a relatively high diagnostic yield, and should therefore be considered in all patients with endoscopically visible tumour.
