Survival and Predictors of Death for Patients with Bronchopulmonary Carcinoid at a Danish Tertiary NET Centre

Background/Aim: Bronchopulmonary carcinoids comprise of typical carcioids (TC) and atypical carcinoids (AC). We present characteristics and associated mortality in patients with TC and AC followed-up at a Danish NET Centre between 2000-2014. Patients and Methods: Data were obtained from medical records, computed tomographic scans, and pathology reports. Mortality was investigated by Kaplan-Meier survival analysis. Results: We included 68 patients, 55 with TC (81%) and 13 with AC (19%). Median follow-up was 5.6 years (range=1.0-26.3). Fourteen patients died; 13 were smokers, and nine had a Ki67 index > 2%. Metastatic disease, smoking and male gender were significantly associated with risk of dying within the first 5 years (log-rank, all p<0.05), while Ki67 index > 2% showed a trend for being associated with risk of death (p=0.11). Conclusion: Survival is strongly associated with tumor type and current/previous smoking. Metastatic disease at diagnosis and male gender are predictors of death within 5 years.
