Se estudian once casos de carcinomas bronquiales in situ o microinvasivos que fueron resecados en un período de tiempo comprendido desde el año 1977 al 1984.

En todos los casos el diagnóstico fue realizado mediante citología de las secreciones obtenidas por lavado y aspirado bronquial. La radiología fue negativa en todos los casos excepto en uno en que había una imagen neumónica. Tos acompañada de esputo hemoptoico, fue el síntoma más frecuente (ocho casos). Un paciente tuvo dolor torácico y neumonitis contralateral y los dos restantes fueron asintomáticos.

El tumor se localizó mediante examen de broncoaspirados selectivos, requiriéndose en algunos casos intervalos largos de tiempo hasta que se realizó el diagnóstico (14 meses en uno de ellos) y varios broncoaspirados (siete). La lobectomía fue el tratamiento quirúrgico más frecuente, en siete casos, seguido de la segmentectomía en tres casos, solamente en un caso se realizó una neumonectomía debido a la gran extensión del tumor en superficie. Estos pacientes tienen un buen pronóstico, aunque tres de ellos han desarrollado un segundo tumor maligno. El estudio de supervivencia oscila entre ocho años para el primer paciente operado, a seis meses para el último paciente.

We report on eleven cases of in situ or microinvasive bronchial carcinomas removed between 1977 and 1984. The diagnosis was always established by cytology of the secretions obtained by bronchial lavage and aspiration. Thorax x-ray study was negative in all patients, except one who showed a pneumonic pattern. The most commonly found symptom (8 patients) was cough accompanied by haemoptoic sputum. One patient complained of thoracic pain and developed pneumonitis on the other side, while the other two patients remained asymptomatic.

Tumours were identified by selective bronchial aspirates examination. Occasionally, long intervals elapsed before establishing the diagnosis (as long as 14 months in one patient) and several bronchial aspirations (as many as seven) were required. Lobectomy, performed in seven patients, was the most frequent surgical approach, followed by segmentectomy, which was indicated in three patients. Only one patient required pneumectomy due to the wide spreading of the tumour. Such patients have a good prognosis, even though three of them have developed a second malignancy. The survival time study of the patients of this series is between eight years for the first patient surgically treated and six months for the last patient recruited.
