1111P New prognostic frontiers for lung neuroendocrine tumors: An Italian-Spanish multicentric study of 200 cases

Abstract

Well-differentiated neuroendocrine tumors of the lung (Lung NET) are classified as typical (TC) and atypical (AC) carcinoids, on the basis of mitotic count and presence of necrosis. However, the identification of prognostic factors, other than TNM stage and histopathological diagnosis of AC versus TC, are still lacking.
