RESUMO
In 88 patients diagnosed and intervened of lung carcinoma, we evaluate the security of the Diagnostic method--cytology: sputum, brushed bronchial, bronchial aspiration, puncture pulmonary aspiration and histology of the bronchial biopsy--when we correlate them with the histology of the dried up tumour. From the 88 patient, in 11 (12.5%) there was a disparity between some specimen and the piece tumour. If we analyze the specimen: the bronchial biopsy, was different in 3 cases, (4.8%); the brushed and the bronchial biopsy, aspiration in 2, (2.7% and 2.3% respectively); the puncture pulmonary aspiration in 6, (26%) and the cytology of sputum in 2 cases, (2.4%). In 8 patients (9%), the outputs of some specimen were not conclusive, if we remove these we find that: the bronchial biopsy was not conclusive in 2 cases, (3.2%), the brushed bronchial in 5, (6.8%); the bronchial aspiration in 9 (10.2%) and the cytology of sputum in 2 cases, (2.4%). With this data we could infer that sometimes the positive outputs of the specimen have no correlation with the histology of the tumour dried up. This disparity has not been observed in the oat-cells. Therefore when we send the specimens to the pathologist, it would always be advisable for him to inform us if there are any different cells belonging to the principal group of the tumor.
