#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.

#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.

#1098 177Lu Dotatate vs Sequential 177Lu Dotatate and 90Y Dotatate: Treatment Outcomes for PRRT Patients at the Christie - A Clinical Audit
Introduction: The traditional treatment regime of somatostatin receptor positive NETs by molecular radiotherapy was based on single radionuclides (e.g. 90Y Dotatate or 177Lu Dotatate), delivered as multiple cycles to allow normal tissue recovery. However a newer practice of alternating tcycles of 177Lu and Y90 Dotatate was implemented at the Christie following introduction of this regime in some European centres. Subsequent follow up studies have indicated that longer overall survival and reduced loss of kidney function is found in patient cohorts treated with combined 177Lu and 90Y regimes to either 177Lu or 90Y alone.

#2698 Safety and Efficacy of Salvage PRRT with 177Lu-DOTA-Octreotate in Patients with Well-Differentiated Metastatic Neuroendocrine Tumours (NET)
Introduction: Peptide receptor radionuclide therapy (PRRT) is an effective therapy in patients with a somatostatin receptor-positive neuroendocrine tumour (NET). NETTER-1 trial demonstrated high efficacy and low toxicity of four cycles.

#2894 Single Institution Experience with Peptide Receptor Radionuclide Therapy (PRRT) in Neuroendocrine Tumors (NET)
Introduction: Neuroendocrine tumors (NETs) are a rare and heterogenous group of tumors with rising incidence. Peptide receptor radionuclide therapy (PRRT) with radiolabeled somatostatin analogue is an encouraging systemic treatment modality with minimum side effects.

#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.

#55 Metronomic combination therapy including temozolamide, bevacizumab and somatostatin analogue for the treatment of malignant gastroenteropancreatic neuroendocrine tumors
Introduction: Malignant gastroenteropancreatic neuroendocrine tumors (GEPNETS), mainly carcinoids, are not considered to be particularly chemotherapy-sensitive to conventional chemotherapeutic schemes. Long-standing evidence suggests these tumors to be highly vascularised and responsive to antiangiogenic strategies. Newest reports demonstrate benefit by the use of temozolamide, an oral alkylating agent similar to intravenous dacarbazine. The DNA repair enzyme O6-alkylguanine–DNA alkyltransferase (AGAT) confers cancer cell resistance to O6-alkylating agents such as temozolamide through its ability to remove methyl/alkyl groups from the O6-position of guanine, thus correcting drug-induced DNA damage.

#66 Adrenocortical cancer: a therapeutic approach with everolimus (RAD001)
Introduction: Adrenocortical cancer (ACC) is a rare disease with very poor outcome. ACC responds poorly to standard chemotherapy. Mitotane, used as adjuvant therapy to surgery, prolongs recurrence-free survival, but the response is limited to 23% of patients and resistance occurs in the majority of patients (1). There is no curative therapy for ACC. Pre-clinical studies have shown involvement of both IGF-2/IGF-1R and Akt/mTOR pathways in ACC, and IGF-1R and mTOR inhibitors inhibited cell proliferation of human adrenocortical carcinoma cell lines in vitro (2,3,4).

#101 Chronic Complications of Peptide Receptor Radionuclide Therapy (PRRT)- A Single Center Experience
Introduction: In the last decade, a new treatment modality, peptide receptor radionuclide therapy (PPRT), has been introduced for gastroenteropancreatic neuroendocrine tumor (GEPNET) patients with non-resectable or progressive disease. PRRT has been associated with several complications, including bone marrow suppression, renal toxicity and hepatic damage.
