P3.09-24 The Concordance of Histological Diagnosis from Transbronchial Biopsy and Resected Specimen of Lung Cancers

Abstract

examination on stamps from surgical material offers a very high percentage of positive results, close to the histological one. But in the tumor size less than 1.0cm, the establishing of the histological type of lung cancer is more difficult by cytological examination. Despite this, the cytology may be extremely useful in diagnose of the small peripheral tumors. The cytological characteristics of small peripheral adenocarcinoma were little reference to the differentiation at the cellular level. Our findings indicated that the presence of several nucleoli and granular chromatin densely are the factors of adenocarcinoma.
