Gastro-Entero-Pancreatic tumors (GEPs) are a subset of Neuroendocrine tumors (NETs) derived from the primitive gut and include digestive and bronchial NETs.
Historically, the gold standard in their functional exploration is the "conventional" somatostatin receptors scintigraphy (SRS) labeled with Indium-111 (Octreoscan®). This reference imaging is complementary to Tomography (CT) and liver MRI. However SRS sensitivity is moderate (60 %), because of its intrinsic detection limits, which could delay the diagnosis or lead to inappropriate therapy.
The use of somatostatin agonists (DOTATOC, DOTATATE, DOTANOC), radiolabeled with gallium-68 (68Ga) enables targeting of Somatostatin receptors (SSTRs) with a PET resolution. This has improved diagnosis of TNE with a gain in sensitivity of over 20% compared to SRS. Furthermore, patient irradiation and imaging protocol are significantly reduced.

Experimental: assesment by 68Ga-DOTATATE PET-CT |
Other: PET-CT |
- interest of the realization of 68Ga-DOTATATE PET-CT in the detection of tumor sites in TNE diagnosis, staging and restaging [ Time Frame: 12-15 months ]
- therapeutic impact of 68Ga-DOTATATE PET-CT in addition to reference imaging (SRS, CT, MRI): we will document the rate of changes in treatment options induced by PET-CT [ Time Frame: 12-15 months ]
