title: Long-term follow-up of classical bronchial carcinoid tumors. Clinicopathologic observations.
abstract: Twenty-seven cases of classical bronchial carcinoid were followed up for at least 10 years after curative resection. Surgery was conservative in 15 cases. True lymph-node metastases were identified at operation in two cases. Distant metastases were confirmed in two patients after 5 and 10 years, respectively. One died of unrelated cause 10 years, and the other is alive 19 years, postoperatively. Radiotherapy relieved bone pain in both cases, and chemotherapy halted disease progression in one of them. In immunostaining the original histologic material, all carcinoids expressed neuron-specific enolase, and most expressed chromogranin A, synaptophysin and serotonin. Demonstration of ACTH and related opiopeptides did not portend a more aggressive course or identify cases with nodal metastases. Despite their low malignant potential, long-term follow-up of bronchial carcinoids is warranted. Even in the rare cases of distant metastases, long-term survival seems to be the rule. The occasional presence of nodal metastases and/or demonstration of ACTH and other opiopeptides, while more frequent in neuroendocrine carcinomas, are not inconsistent with bronchial carcinoids and seemingly do not alter their overall favorable prognosis.
