Histology, not lymph node involvement, predicts long-term survival in bronchopulmonary carcinoids

Am Surg. 2011 Dec;77(12):1669-74.

Abstract

Recently, the incidence of bronchopulmonary carcinoid has increased substantially, whereas survival associated with both subtypes has declined. We reviewed our experience with bronchopulmonary carcinoid to identify factors associated with long-term survival. We reviewed our cancer registry from 1985 to 2009 for all patients undergoing surgical resection for bronchopulmonary carcinoid. Cox regression analysis was used to evaluate prognostic factors. Fifty-two patients met criteria for inclusion. Forty-three patients (82%) presented with typical histology. The likelihood of lymph node metastasis was similar for patients with typical histology and patients with atypical histology. For patients with typical histology, the 5-year survival rates with and without lymph node metastases were 100 per cent and 97 per cent, respectively (P = 0.420). The overall survival rate for patients with typical histology (97% at 5 years; 72% at 10 years) was significantly better than for patients with atypical histology (35% at 5 years, 0% at 10 years) (P < 0.001). Univariate and multivariate analyses demonstrated that long-term survival was associated with histology but not lymph node involvement (hazards ratio = 14.6, 95% confidence interval: 1.7, 125.2). Our data suggests that long-term survival is associated with histology, not lymph node involvement. We found tumor histology to be the strongest predictor of long-term survival in patients with pulmonary carcinoid tumors.
