[Bronchial cytology of "occult" lung cancers (author's transl)].
Having underlined the value of bronchial cytology for the early diagnosis of lung cancers, the authors report 7 observations concerning a particular clinical form: the "occult" lung cancer with a malignant cytological precession more or less in advance in relation with the radiological or fibroscopical data. Malignant cells can be found in sputum from 9 months to 8 years beforehand. All histological types can be seen but no cancer of the anaplasic type with small cells was identified either in this series or in the literature. The authors insist also on the difficulty in localizing these cancers in situ at a very early stage. They set apart the insufficiencies of the X-ray results in several observations and the limits of other investigating techniques (bronchography, scintigraphy, echotomography, ...). These tumours seem to have a mild evolutivity.
