#4114 Delays in the dosing administration of PRRT in advanced neuroendocrine tumors – Is there an adverse impact?

Introduction: Peptide receptor radionuclide therapy (PRRT) has emerged as a major therapeutic component in the overall management of advanced neuroendocrine tumors (NETs). In Greece, the treatment has been performed for several years, however because of reimbursement issues, especially during the financial crisis in Greece, there is usually a delay between the administered doses beyond the recommended 6-8 weeks interval.

#3995 Pelvic metastases in patients with neuroendocrine tumors: A rare site of metastases

Introduction: Pelvic metastases (PMs) in patients with neuroendocrine tumors (NETs) are rare and develop predominately in women with small intestinal NETs (Si-NETs). The characteristics of NET related PMs and the efficacy of different management options have been poorly investigated.
