#4590 Association of SST5TMD4 and SST5TMD5 expression with metastasis and poor prognostic markers in gastroenteropancreatic neuroendocrine tumours

Introduction: The expression of the somatostatin receptor isoform SST5TMD4 is linked to poorer prognosis in somatotropinomas, as well as in breast and thyroid cancers, and it is notably overexpressed in gastroenteropancreatic neuroendocrine tumours (GEP-NETs).

#2058 On-going Evaluation of the Use of Resources and the Costs (UR/C) Associated with Controlled or Uncontrolled Carcinoid Syndrome (CS) in Patients (pts) with Neuroendocrine Tumours (NETs): RECOSY Study Design

Introduction: NET pts have high rates of mortality and morbidity, as wells as decreased health-related quality of life (HRQoL) due to CS. Though there is little research on the economic impact of CS, recent studies show that some symptoms, i.e. diarrhoea, are associated with higher healthcare expenditure and use of resources.

#154 Long-term disease stabilization in a patient with advanced pancreatic neuroendocrine tumor treated with combined everolimus and octreotide LAR after prior failure of cytotoxic therapy

Introduction: Targeting of multiple pathways has become an important strategy for improved tumor control in metastatic neuroendocrine tumors (NETs). Among these targets is the mammalian target of rapamycin (mTOR), a central regulator of cell growth, proliferation, and apoptosis, which is blocked by everolimus, an oral inhibitor of mTOR that has shown efficacy in patients with metastatic pancreatic NETs. Recent evidence has suggested that suppression of insulin-like growth factor-1 receptor (IGF-1R) secretion with octreotide therapy, along with concurrent inhibition of mTOR by everolimus, may improve tumor control synergistically by preventing feedback activation of the PI3K/Akt/mTOR pathway.
