Plain-language summary
An international multi-centre, open, randomised, parallel-group phase II study comparing adjuvant treatment with 177Lu-DOTATATE to best supportive care in patients after complete surgical removal of neuroendocrine liver metastases.
In this study, adjuvant treatment with 177Lu-DOTATATE will be compared with best supportive care in patients with well differentiated grade 1 or 2 neuroendocrine tumours in the stomach, pancreas or gut (gastro-entero-pancreatic NETs) who had their primary tumour already removed or in whom both primary and liver tumour metastases removal will take place simultaneously, including removal of perihilar lymph nodes will be eligible.
The primary objective is to compare overall disease-free survival at 3 years after treatment with 177Lu-DOTATATE to best supportive care between both treatment arms, with equal chances of entering either arm (1:1)
Secondary objectives are to describe and compare the difference in disease-free survival in the liver, overall survival, time to the next anticancer treatment, the cost effectiveness and health-related quality of life. The safety and toxicity of 177Lu-DOTATATE as adjuvant therapy will also be described.
Additionally, the clinical use of blood and urine analysis test (NETest) will be evaluated to identify microscopic remaining disease and detect early the return of the tumour.

. Patients aged 18 years or older
. ECOG / WHO performance status 0 or 1
. Patients with well differentiated grade 1 or grade 2 (Ki67\<20%) GEP NET confirmed by histological criteria with the primary localisation in stomach, pancreas, or gut

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. MRI scan prior to surgery (within 4 -6 weeks) confirming liver metastases and no extrahepatic disease (except resectable perihilar lymph node involvement and/or primary tumour, if still in place)
