Complex examination using fiber bronchoscopy under local anesthesia with urgent cytologic examination of samples was performed in 206 outpatients with clinically suspected lung cancer. Malignancy was diagnosed in 138 cases. Tumor was cytologically confirmed in 95.7% of cases; its pattern was established in 88.7%. It is inferred that cytologic method improves the diagnostic potential of fiber bronchoscopy and assures shorter duration of outpatient examination.
