Bronchial carcinoid tumors: a retrospective analysis of 126 patients.
From 1970 until 1990, 8,958 cases of primary carcinoma of the lung were diagnosed at the Duke University Medical Center. During the same period, 126 patients (mean age, 53 +/- 13 years) were diagnosed with bronchial carcinoid. The overall survival was 78% for 5 years and 71% for 10 years. Surgical treatment in 106 patients included pneumonectomy (15), lobectomy (63 with 9 bronchoplastic procedures), stapled wedge resection (22), and bronchoscopic laser resection (6). The method of diagnosis was chest roentgenography (121), chest computed tomography (77), mediastinal tomography (31), bronchoscopy (81), bronchoscopic brushing and washing (50), bronchoscopic biopsy (40), transthoracic needle biopsy (27), thoracotomy (100), and autopsy (5). Univariate analysis of the medical history, presenting signs and symptoms, diagnostic test results, and pathologic data predicted improved survival (p less than 0.001) for: female sex (n = 58), asymptomatic presentation (n = 47), normal serum serotonin or urinary hydroxyindoleacetic acid levels (n = 76), peripheral location of the primary tumor (n = 50), pathologic stage I or II (n = 91), negative lymph nodes (n = 80), primary tumor 2 cm or less in diameter (n = 67), and typical histology (n = 80). No significance (p greater than 0.1) was observed for age, smoking history, race, family history of carcinoid, environmental exposure, or hemoptysis. The most important factors affecting survival defined by multivariate analysis were (p less than 0.01) pathologic stage, atypical histology, and asymptomatic presentation. Bronchial carcinoid tumors are unique, making up 1% to 2% of primary lung neoplasms and having an excellent prognosis after resection with a 95% 5-year and 93% 10-year survival for pathologic stage I disease.
