#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.

#3801 Local treatment of neuroendocrine liver metastases – How effective and safe is stereotactic microwave ablation?

Introduction: The less invasiveness of local ablation techniques such as stereotactic microwave ablation (SMWA) for the treatment of malignant hepatic lesions has made it an attractive alternative to conventional surgical resection.

#3251 Impact of Wnt signalling on CXCR4 expression and function

Introduction: Loss of Somatostatin Receptor 2 (SSTR2) expression and rising Chemokine Receptor Type 4 (CXCR4) expression are associated with increasing dedifferentiation in Neuroendocrine Tumors (NET). CXCR4 expression is associated with enhanced metastatic and invasive potential and worse prognosis in NET, but might be a theranostic target in NET not sufficiently expressing SSTR2. Likewise, aberrant activation of Wnt/β-catenin signalling may promote a more aggressive phenotype in NET.
