Plain-language summary
Peptide receptor radionuclide therapy (PRRT) with \[177Lu\]Lu-\[DOTA0,Tyr3\]octreotate (177Lu-Dotatate) is an effective and safe treatment for patients with metastatic gastroenteropancreatic neuroendocrine tumors (GEP NET). While 177Lu-Dotatate prolongs progression-free survival (PFS) and preserves quality of life (QoL), objective response rates (ORR) remain limited. Capecitabine, as radiosensitizer, could increase efficacy without increasing 177Lu-Dotatate activity. This phase II randomized controlled trial investigated the additional cytotoxic or radiosensitizing effect of capecitabine in combination with 177Lu-Dotatate.
Patients with advanced somatostatin receptor positive GEP NET or bronchopulmonary NET were included to receive four cycles of 7.4 GBq 177Lu-Dotatate and capecitabine or 177Lu-Dotatate alone. Capecitabine (1650 mg/m2/day) was administered for two weeks from the start of each PRRT cycle. Primary endpoints were ORR, PFS and median overall survival (OS). Secondary endpoints included biochemical response, adverse events and QoL.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Presence of histology proven GEP tumor(s), including bronchial carcinoids.
. Presence of somatostatin-receptors on the known tumor lesions demonstrated by OctreoScan® within 6 months of the first dose of radiolabelled octreotate/octreotide. The uptake on the octreoscan should be at least as high as normal liver uptake on planar imaging.
. Life expectancy greater than 12 weeks
. Serum creatinine ≤150 μmol/liter or 1.7 mg/dL, and a measured creatinine clearance (or measured GFR using plasma clearance methods, not gamma-camera based) of ≥50 mL/min.
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?

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.

. Serum albumin \> 30 g/L, or serum albumin ≤ 30 g/L but normal prothrombin time.
. Karnofsky Performance Status ≥ 60.
Exclusion criteria
. Possible surgery with curative intent.
. Surgery, radiotherapy, chemotherapy, or other investigational therapy within 3 months of the start of therapy.
. Patients with known brain metastases unless these metastases have been treated and stabilized for at least six months prior to study start. Patients with a history of brain metastases must have a head CT with contrast to document stable disease prior to study start.
. Uncontrolled congestive heart failure.
. Any subject who is taking concomitant medications which decrease renal function (such as aminoglycoside antibiotics).
. Any subject receiving therapy with somatostatin analogues, unless the dose has been stable for at least 3 months prior to the first cycle in this study and the disease status during these 3 months has been documented by SWOG criteria as described in this study.
. Any subject receiving therapy with short-acting somatostatin analogues in whom these analogues cannot be interrupted for 12 hours before and 12 hours after the administration of the radiolabelled somatostatin analogues, or any subject receiving therapy with long-acting somatostatin analogues in whom these analogues cannot be interrupted for at least 6 weeks before the administration of the radiolabelled somatostatin analogues, unless the uptake on the Octreoscan during continued somatostatin analogue medication is at least as high as normal liver uptake on planar imaging.
. In patients with unusual hematological parameters, including an increased MCV (\>105 fL), and especially in those who had previous chemotherapy, the advice of a hematologist should be seeked, for adequate further work-up.
