Bronchial carcinoid: a clinical follow-up study of 33 cases.
Thirty-three bronchial carcinoid tumours operated on in a 22-year period are reviewed. They were histologically verified as typical carcinoids with Grimelius' argryophilic staining (25 cases), electron microscopy (6) and immunostaining for synaptophysin (4). Nineteen were endobronchial and 14 peripheral, intraparenchymal tumours. Lymph-node metastases were present at operation in two patients. Two tumours, in patients with Cushing's syndrome, were hormonally active (one secreting ACTH and the other ACTH and calcitonin). There was one case of multiple endocrine neoplasia syndrome, but none of carcinoid syndrome. During follow-up for 5-18 (mean 8.2) years five patients died of unrelated causes. Only one patient showed distant metastasis (after 15 years in salivary gland and a year later in mediastinal fat). Extensive clinical re-examination was performed on 20 patients, and six others were interviewed. All were well but one, who died of uterine cancer 8 weeks later. Typical bronchial carcinoid is concluded to be of low-grade malignancy and suitable for limited pulmonary resection.
