Definition
A well-differentiated neuroendocrine neoplasm that arises from the lung. It is characterized by the presence of uniform polygonal cells with small or moderate amount of cytoplasm and inconspicuous nucleoli. The cells are usually arranged in organoid and trabecular patterns. It is classified as grade 1 (G1-typical carcinoid tumor) or grade 2 (G2-atypical carcinoid tumor) based on the number of mitotic figures and the absence or presence of necrosis. Grade 2 neuroendocrine tumors have a worse prognosis.

Names
CancerIndex is a research and information platform. It does not diagnose and does not recommend treatment.
Key figures
Each figure carries its unit, period and source; ranks link to "Why this rank?".
No registry-level ancestor: burden figures are published for the mutually exclusive top-level site groups only, and this entity does not descend from one. Global figures (IARC / GLOBOCAN) stay under license review and SEER awaits credentials.
