[Cytological classification of bronchial carcinoma (author's transl)]

Reliability of cytological classification of tumours from material obtained from sputum or bronchial secretion was tested on 116 histologically confirmed cases of bronchial carcinoma. Squamous-cell carcinoma and small-cell undifferentiated carcinoma were most often correctly classified, results being less good with large-cell undifferentiated carcinoma, adenocarcinoma taking an intermediary position.
