title: [Bronchiolo-alveolar cell carcinoma].
abstract: 15 cases of bronchiolo-alveolar cell carcinoma were observed at the Dept. of Surgery of the University Hospital of Zurich from 1961 to 1976. The mean age of these patients was 56 years. The sex distribution was 13 males and 2 females. Five cases were discovered accidentally; the symptoms of the remaining 10 were uncharacteristic. Cytology, bronchoscopy and mediastinoscopy were negative at early stages. Diagnosis was made by histologic examination of the specimens only. Needle biopsy, performed routinely over recent years, proved helpful in 4 cases. In 12 out of 14 patients, lobectomy was considered 'radical'; nevertheless, only 2 survived more than 5 years. The disseminated form of the bronchiolo-alveolar cell carcinoma is characterized by a particularly poor prognosis. According to our experience and to the literature, only the solitary, nodular type shows a more favourable outlook.
