Overview
Common causes of carcinoid syndrome include genetic disorders (multiple endocrine neoplasia type 1 and neurofibromatosis type 1) and genetic mutations (gains involving chromosomes 5, 14, 17, and 19 and losses involving chromosomes 11 and 18).
Causes
- 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]
- other common causes of carcinoid syndrome includes are mostly genetic:[2]
