[Macroscopic evaluation of bronchial mucosa and histological diagnosis in relation to localization of neoplastic...

In 140 lung cancer patients fiberoptic bronchoscopy with biopsy and BAL procedure were performed in diagnostic process. Obtained results of macroscopic changes were analyzed in relation to histological diagnosis and localization in the bronchial tree (central and peripheral). Squamous cell lung cancer was the most often diagnosed in central localized tumors and adenocarcinoma in peripheral ones. Macroscopic changes were more evident and more characteristic for cancer process in central localized tumors. In peripheral changes non-characteristic, inflammatory-like symptoms were determined.
