#2996 A Head-to-Head Comparison between Two Software Packages for Hybrid Dosimetry after PRRT
Introduction: The number of dosimetry studies after PRRT is increasing, yet different methodologies are used which challenge comparison or pooling of results.

#2863 Introduction of Dosimetry on PRRT Practice. A Useful Tool to Detect Responders and Evaluate Treatment Safety
Introduction: PRRT is a recognized salvage option for G1-G2 GEPNET. Currently, the Italian protocol (Lutathera AIFA Guidelines) consists in four fixed-dose of 177 Lu-DOTATATE. The dosimetry has recently been recognized as an important tool to guide PRRT but is not yet part of routine practice.

#153 Antibody formation against somatostatin analogues with altered biodistribution and dosimetry: a case with implications for PRRT
Introduction: Peptide receptor radionuclide therapy (PRRT) of neuroendocrine tumors (NETs) has emerged as a powerful palliative therapy. I.v. administration of radiolabeled (e.g. Yttrium-90) somatostatin analogues (SA) results in high-dose local irradiation of all tumor sites. The radiolabelled SA accumulates in the tumors through receptor-mediated internalization depending on the expression of somatostatin receptors and the pharmacokinetics of the radiolabelled SA.

#335 Dosimetry with 111In-octreotide and Coinfusion of Amino Acids in the Prediction of Nephrotoxicity in Neuroendocrine Tumors after PRRT with 90Y-DOTATOC
Introduction: Kidneys are the critical organs in PRRT. A dosimetry protocol was implemented in an ongoing study to estimate the biological effective dose (BED) on the kidneys after 90Y-DOTATOC therapy.

#698 Feasability of a Dosimetry Guided Therapy Planning for Peptide Receptor Radionuclide Therapy with 177Lu-DOTA-Octreotate
Introduction: The efficacy and safety profile of PRRT can theoretically be optimized by planning each individual patient treatment on the absorbed dose to the critical organs and tumor lesions.

#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.

#2066 Pretherapeutic Predictors of Tumor Absorbed Dosimetry in Radionuclide Therapy for Metastatic Neuroendocrine Tumors
Introduction: Pretherapeutic 68Gallium-DOTA-(0-Tyr3)-octreotate Positron Emission Tomography (68Ga-DOTATATE PET) standardised uptake value (SUV) has shown conflicting results in the prediction of tumour lesion absorbed dosimetry (TLAD).

#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.

#2998 Inter- and Intrapatient Mean Absorbed Dose Variation and Simplification of Dosimetric Workflow after PRRT
Introduction: Post-PRRT dosimetry is not routinely performed, partly due to required multiple imaging time points. One time point imaging would reduce patient burden, and make dosimetry more applicable in the clinical settings.
