Correlation between clinical and pathological factors in resected lung carcinoid tumours

Background: in carcinoid tumours, the need for refinement of pathological classification, influence of the carcinoid syndrome in N1 disease and the role of adjuvant treatment are still controversial. Methods: retrospective study including patients who underwent a lung resection for bronchial carcinoid tumours in a recent 10-years period. Results: a total of 52 patients (typical - group 1 and atypical - group 2) with 26 patients each, underwent a lung resection for lung carcinoid tumours, representing around 2.5% of patients operated for malignant lung tumours. The M:F for typical and atypical subtypes was 1.14 and 1.16: 1, respectively. The patient distribution within age intervals of 50 years for typical carcinoids was 19.3, 30.7 and 50%, respectively; for atypical carcinoids, it was 7.7, 34.6 and 57.7%, respectively (P Conclusion: there are some differences between typical and atypical carcinoids whose prognostic significance needs to be assessed on bigger patient populations.
