#2280 The BON-SSTR2 Chicken Chorioallantoic Membrane (CAM) Model for the Analysis of Lu-17-DOTATOC Sensitizing Agents
Introduction: Peptide radioreceptor therapy (PRRT) is a promising therapy option for SSTR2-positive pancreatic neuroendocrine neoplasms (NEN). However, therapeutic effects are often not satisfying concerning sensitivity to PRRT. We hypothesize that the slow proliferation of NENs provides sufficient time for the repair of beta-particle induced-DNA damage. The ubiquitin-proteasome-system is involved in DNA damage repair and affected by the proteasome inhibitor bortezomib (Velcade®). The inhibition of DNA damage repair during PRRT may be an option to improve therapy response in NEN. We have recently demonstrated the damage repair inhibitory and pro-apoptotic effect of bortezomib in NEN in vitro (Briest et al., in revision).

#80 Metastatic growth hormone secreting pituitary carcinoma treated with peptide receptor radionuclide therapy
Introduction: Pituitary carcinoma (PC) is an extremely rare condition defined by the presence of adenohypophyseal neoplastic tissue outside the pituitary. Clinical experience regarding diagnosis, management and prognosis of PC is very limited. Growth hormone (GH) secreting PC is even rarer and represents a particular challenge to clinical practice. Therapeutic modalities utilized to treat PC include surgery, radiation, hormonal therapy, and cytotoxic drugs. Peptide Receptor Radionuclide Therapy (PRRT) is an emerging therapeutic modality that involves the targeted delivery of an ablative dose of radiolabelled somatostatin analog. PRRT has been applied to various neuroendocrine tumors and results in prolonged survival and enhanced quality of life. As yet, this therapy has not been applied to malignant pituitary tumors.

#156 Toxicity, response and survival analyses of Peptide Receptor Radionuclide Therapy (PRRT) in treatment refractory metastatic thyroid cancer using Yttrium-90 and Lutetium-177 Labeled somatostatin analogs
Introduction: Medullary thyroid carcinoma (MTC) represents about 3-16% of thyroid cancer. After first line treatment, therapeutic options for locally recurrent or metastasizing tumors include repeated surgery, whenever possible. Doxorubicin containing chemotherapy regimens in iodine-nonavid differentiated thyroid cancer have poor efficacy.

#161 Low Dose Multiple Cycle (LD/MT) Peptide Receptor Radionuclide Therapy: a new concept for the treatment of well-differentiated metastatic neuroendocrine tumors
Introduction: It has been shown experimentally that low dose radiation can effectively kill slow growing cancer cells. Also, external beam radiation therapy applies a fractionated delivery of radiation dose to reduce toxicity with equal or even better therapeutic efficacy.

#411 Efficacy of Peptide Receptor Radionuclide Therapy Treatment with 177Ludotatate in Advanced Well-Differentiated Pancreatic Neuroendocrine Tumors
Introduction: Peptide receptor radionuclide therapy with 177Lu-DOTATATE (177Lu-PRRT) has shown activity against advanced well-differentiated pancreatic neuroendocrine tumors (P-NET) in previous phase I/II studies.

#2159 Hepatic Steatosis Secondary to Peptide Receptor Radionuclide Therapy with Somatostatin Analogue
Introduction: Peptide Receptor Radionuclide Therapy (PRRT) with 177-Lutetium-DOTA-TATE is a therapeutic modality for neuroendocrine tumors. It has some well known side effects, concerning specially the bone marrow (from cytopenias to myelodysplastic syndrome), in addition to mild renal effects. Hepatotoxicity from PRRT is still being studied.

#13 Neoadjuvant peptide receptor radionuclide therapy for an inoperable neuroendocrine pancreatic carcinoma
Introduction: Pancreatic endocrine tumors (pNETs) are rare but are among the most common neuroendocrine neoplasms of the abdomen. At diagnosis, many of them are already advanced and difficult to treat.

#236 Very Long-term Follow-up (> 5 years) of Renal Function of Neuroendocrine Tumor Patients Treated with Five or More Cycles of Peptide Receptor Radionuclide Therapy (PRRNT)
Introduction: Nephrotoxicity is one of the primary concerns in neuroendocrine tumor (NET) patients (pts.) treated with peptide receptor radionuclide therapy (PRRNT).

#567 Efficacy of Combined Peptide Receptor Radionuclide Therapy and Radiofrequency Ablation for the Management of Hepatic Metastases of Neuroendocrine Tumors
Introduction: Hepatic metastases significantly affect the overall prognosis and quality of life in patients with gastroenteropancreatic neuroendocrine tumours (GEP-NET). Radiofrequency ablation (RFA) is one of the important local ablative strategies for hepatic metastases. Peptide receptor radionuclide therapy (PRRNT) is a well-established therapeutic modality for metastatic NET.
