Although pan-NET are quite rare, the incidence is on the rise and together with other abdominal neuroendocrine tumours an approximate incidence in Sweden would be 850 patients per year extrapolating from Norwegian data. Pan-NET are divided into symptomatic hormone producing tumours (such as insulinomas\u002Fglucagonomas\u002FVIPomas) or non-functioning tumours that often are asymptomatic. As early symptoms often are lacking in non-functioning-pan-NET, many patients present with distant metastases and are thus beyond a curative surgical approach at the time of diagnosis. Metastatic non-functioning pan-NETs present a significant challenge and the optimal management remains a subject of debate.\n\nThis is a prospective, two armed, parallel, randomised, controlled, international multi-centre study, aiming to investigate if a near-total tumour debulking (intervention) in metastatic (stage 4) GI-WHO grade 1-2 pan- NET, with or without oncologic treatment, is superior to oncologic treatment alone (control), with regards to overall survival, health-related quality of life, participant performance status, time until hospitalisation, adverse event characteristics and cost in the short and long term.",[113],"Pancreatic Neuroendocrine Tumor",[115,116,22,117,118],"Pan-NET","Stage 4","Non-functional Pan-NET","GI-WHO grade 1-2 Pan-NET","2026-01-21",{"date":121,"type":122},"2026-01-22","ACTUAL",{"date":124,"type":122},"2026-01-09",{"date":126,"type":107},"2033-05-31",{"name":5,"class":6},4]
