MEN1 환자에서 췌장 NET는 30-80% 동반된다. 증상 및 악성 가능성이 있는 경우 수술적 절제가 예후에 중요한 영향을 미친다. 수술이 불가능한 췌장 NET에 대해 EUS-EI를 고 려할 때는 합병증과 불완전 치료 및 재발 가능성에 대한 주 의 깊은 고려가 필요하다.
Multiple endocrine neoplasia type 1 (MEN1) is a rare inherited disorder caused by mutations in the MEN1 gene on chromosome 1. Clinical diagnostic criteria for MEN1 include the presence of two or more endocrine tumors such as pituitary, parathyroid, and pancreatic islet tumors. Treatment is needed for tumors accompanied by symptoms or having malignant potential. Malignant neuroendocrine tumors (NETs) are the major cause of MEN1-related death, and pancreatic NETs account for 30- 80% of MEN1 cases. Surgery is the mainstay curative treatment, and endoscopic intervention is a treatment option when patients are poor candidates for surgery. A 33-year old female patient with MEN1 was treated via endoscopic ultrasonographyguided ethanol injection for a pancreatic NET.
