• Approximately 30-40% of patients with well-differentiated neuroendocrine tumors present with carcinoid syndrome.
• Carcinoid syndrome is predominantly associated with neuroendocrine tumors (NETs) that arise from the midgut in the setting of extensive liver metastases
• Carcinoid syndrome may be present in patients with bronchial carcinoids.^[1]
