Preclinical Evaluation of Novel Combinations of 177-Lutetium Octreotate with Molecular Targeted Agents in Neuroendocrine Tumor Models Abstract #613

Introduction: Peptide receptor radionuclide therapy (PRRT) has been valuable in the treatment of somatostatin receptor-2 (SSTR2) expressing neuroendocrine tumors (NET) but more effective clinical regimens are needed.
Aim(s): To develop preclinical NET models and use these to identify novel therapeutic regimens combining radiosensitizing agents and PRRT with improved efficacy for evaluation in the clinical setting.
Materials and methods: We have characterized a panel of NET cell lines for their SSTR2 mRNA and protein expression, in vivo growth properties, in vivo uptake of the PET imaging tracers, FDG and Ga-68 octreotate and in vivo sensitivity to Lu-177 octreotate (Lutate) and a range of chemotherapy drugs.

Introduction: Peptide Receptor Radionuclide Therapy with 177Lu-DOTATATE is gaining acceptance as safe and effective therapy for inoperable neuroendocrine tumors (NET). A radiosensitizing chemotherapeutic drug -capecitabine, the prodrug of 5-Flourouracil, is included in the protocol to further enhance therapeutic efficacy.

Introduction: For the small and large cells poorly differentiated neuroendocrine carcinomas (PDNECs) emergency treatment remains the combination cisplatin/etoposide. However, recent studies suggest that targeted therapies could be a therapeutic option for this group of highly aggressive carcinomas.

#1506 Somatostatin Analogs and mTOR Inhibitors as Radioprotectors or Radiosensitizers in Neuroendocrine Tumor Cells
Introduction: PRRT can deliver radiation doses of up to 250 Gy to the tumors. Nevertheless, complete remission is extremely rare, compared to similar radiotherapies for thyroid cancer and non-Hodgkin lymphoma.
