1. Ninety-seven cases of proved bronchogenic carcinoma were bronchoscoped in a one-year period. Saline bronchial washings were obtained in all cases. [SEE TABLE 2 IN SOURCE PDF].
2. Positive sputum for tumor cells was less frequent when the lesion was not bronchoscopically visible indicating the need for more extensive sputum studies in these cases.
3. Where the neoplastic lesion was not visible bronchoscopically, the yield of positive cytological findings in the saline washings was less than ten per cent.
4. Bronchoscopy, merely for the purpose of obtaining bronchial washings, does not appear to be justifiable.
