Fiberoptic bronchoscopy. Comparison of procedures used in the diagnosis of lung cancer
BA Chaudhary, K Yoneda and NK Burki
We have compared the relative value of various techniques used in
association with fiberoptic bronchoscopy for the diagnosis of lung cancer.
We analyzed the results in 114 patients who underwent diagnostic fiberoptic
bronchoscopy and in whom a definite histologic diagnosis of lung cancer was
made. A comparison of the diagnostic yield from cytologic examination of
prebronchoscopy and postbronchoscopy sputum and of fiberoptic bronchial
biopsy, brushing, and washing was made. Over-all, bronchial washings gave
the highest diagnostic yield (75.4%) and forceps biopsy the next higher
(65.8%). The combination of bronchial washings and forceps biopsy gave the
highest diagnostic yield (95.8%). In six patients, postbronchoscopy sputum
was the only source of positive diagnostis; in 20 patients only one
procedure was positive. Our results suggest that although fiberoptic
bronchoscopy washings and forceps biopsy have the highest diagnostic yield,
brushings and postbronchoscopic sputum examination are also important
diagnostic maneuvers and should be routinely performed.
