New scan criteria could sharpen cancer response readings
NCT ID NCT06448208
First seen Jun 25, 2026 · Last updated Jul 24, 2026 · Updated 3 times
Summary
This study aims to create better guidelines for reading PET scans in people with neuroendocrine tumors. Researchers will compare new criteria against the current standard to see which better predicts if a tumor shrinks, grows, or stays the same. The study involves 11 participants who are already scheduled for standard treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could give doctors a more accurate way to read PET scans for neuroendocrine tumors, helping them better decide if a treatment is working.
- What could go wrong
- This is a very small study (11 people) that only tests a new way to look at scans, not a new treatment. The new criteria may not prove better than the current standard.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Subjects affected by histologically proven, somatostatin-receptor positive, metastatic or inoperable well-differentiated G1, G2 or G3 neuroendocrine tumors (NETs) candidate to receive PRRT with 177Lu-DOTATATE per standard of care. Inclusion Criteria: 1. Histologically proven or cytologically confirmed, metastatic or inoperable NETs 2. Measurable disease as defined by RECIST 1.1. 3. Overexpression of somatostatin receptors of the target lesions at somatostatin receptor imaging (68Ga-DOTATATE or 64Cu-DOTATATE PET/CT) with SUV of lesions greater than normal liver at least in 1 metastasis. Exclusion Criteria: 1. Neuroendocrine Carcinoma), small and large cell type; MIxed Neuroendocrine-Nonneuroendocrine Neoplasm (MiNEN). 2. Presence of somatostatin receptor negative lesions.
