Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with histologically confirmed grade 1 or 2 neuroendocrine tumors that are inoperable or metastatic.

Probably not a fit

Patients who have previously received Lu-177 oxodotreotide or have contraindications to this treatment may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective, multicenter, open-label study aims to assess the Inflammation Based Index (IBI) score as a predictive marker for clinical and radiological responses in patients with inoperable or metastatic, progressive grade 1 or 2 intestinal neuroendocrine tumors treated with Lu-177 oxodotreotide. The IBI score is calculated based on C-reactive protein and albumin levels, categorizing patients into low, intermediate, or high mortality risk. The study will involve additional blood tests and data collection to evaluate the effectiveness of the IBI score in predicting treatment outcomes.

Why it matters

Potential benefit: If successful, this study could provide a reliable biomarker to predict treatment responses, potentially improving patient management and outcomes.

How similar studies have gone: While the use of inflammatory markers as predictive tools is established in other contexts, this specific application of the IBI score in neuroendocrine tumors is novel and has not been extensively tested.
