Comparative Study between the Macroscopic Pathological Findings and Bronchoscopical Findings and Difficulties in Detection of the Sites of Early-Stage Lung Cancer

Abstract

The recent rapid increase in cases of lung cancer has necessitated the early detection and correct diagnosis of incipient lung cancer in the hilar region of the lung. Bronchial fiberscopy is very valuable for definitive diagnosis, in particular for the diagnosis of the site of the cancer in so-called occult lung cancer cases. Therefore, the authors carried out clinical and pathological studies in our 16 cases of early lung cancer at the hilum region of the lung.
