Bronchial adenoma. Clinicopathologic study and results of treatment.

Among 1,700 primary tumors of the lung, there were 53 cases of bronchial adenoma (3.1 percent); 38 (72 percent) of the 53 were typical carcinoids, and the remaining 15 were of a higher grade of malignant neoplasm. There was a slight predominance of female patients, and the age of greatest incidence was between 30 and 50 years (31/53; 58 percent). The most frequent localization was in the main bronchi and in the left bronchial tree. In cases of higher grades of malignant neoplasm, extensive bronchopulmonary resections were performed, while in the less active and less metastatic carcinoids, partial resections were generally performed, using bronchoplastic techniques, sleeve resections, and grafts, except in those cases in which bronchial obstruction had produced extensive and irreversible lesions. Survival at five and ten years after surgery is presented.
