#2119 Positron Emission Tomography (PET) Predictors of Tumor Response to Peptide Receptor Radionuclide Therapy (PRRT) in Metastatic Neuroendocrine Tumors (NET)

Introduction: Pretherapeutic 68Gallium-DOTA-(0-Tyr3)-octreotate (68Ga-DOTATATE) PET standardised uptake value (SUV) has shown conflicting results in the prediction of tumour response to radionuclide therapy.

#2069 Tumor Absorbed Dosimetry and Response of Radionuclide Therapy in Metastatic Neuroendocrine Tumor

Introduction: Increased tumour lesion absorbed dosimetry (TLAD) from peptide receptor radionuclide therapy (PRRT) is associated with neuroendocrine tumours (NET) response. Responses to PRRT might be impacted by NET grade, site of origin and use of concurrent chemotherapy.

#1425 Dosimetry to Estimate the Effect of Gelofusine® on the Renal Absorbed Dose of Lutetium 177-DOTA-octreotate.

Introduction: Lutetium-177 DOTA-octreotate (LuTate), a radiolabelled somatostatin analogue, delivers targeted radiation to neuroendocrine tumours and metastases. Healthy tissues also receive significant irradiation. Charged amino acids are routinely co-infused to block renal proximal tubular LuTate reabsorption. Gelofusine® (a succinylated bovine gelatin molecule), proposed to interact with the megalin/cubulin receptor-mediated transporter system, has been shown to reduce renal uptake of indium-111 octreotide. Routine Gelofusine® administration is limited by risk of allergic reaction.

#1263 Pretherapy Identification of Patients at Risk of Receiving a High Renal Dose Undergoing Peptide Receptor Radionuclide Therapy

Introduction: 68GaDOTA TATE imaging of patients with neuroendocrine tumours has shown that tumour sequestration is a major factor leading to a sink effect that decreases activity concentration in healthy tissues, particularly the renal parenchyma.
