Atypical carcinoid: 50-70% 5-year survival 3. Large cell neuroendocrine carcinoma: 20-40% 5-year survival 4. Small cell lung cancer: 5-10% 5-year survival Note: Pulmonary carcinoid is a complex condition, and treatment decisions should be made in consultation with a healthcare professional. #Pulmonarycarcinoid
