The management of small (pNET) in both MEN1 and sporadic cases, pose a major clinical challenge. At present, pancreatic surgery is the only curative treatment but it is associated with high morbidity. To reduce the morbidity ascosiated with surgery and thereby potentially improve quality of life for MEN1 patients introduction of less invasive techniques for treatment of pNET is important. High-dose-high precision MR-guided radiotherapy (MRgRT) holds promise as a new less invasive treatment option for pNET. The aim of this study is to assess efficiacy and safety of MRgRT for treatment of pNET in MEN1 patients.",[27,28],"Neuroendocrine Tumor of Pancreas","Multiple Endocrine Neoplasia Type 1","RECRUITING","2024-12-16",{"date":32,"type":33},"2024-12-18","ACTUAL",{"date":35,"type":33},"2022-05-01",{"date":37,"type":21},"2026-12-01",{"name":39,"class":40},"J.M. de Laat","OTHER",""]
