[Cytological examination of bronchial secretions in lung tumours, correlated with the tumour stage (TNM system) (author's transl)].
Brochial secretions were examined cytologically in 2114 patients (2322 secretion samples).  Among the 1006 patients with confirmed malignant lung tumour bronchial secretions were positive in 56%.  The result depended on the size, type, and site of the tumour and its stage according to the TNM system.
