#4607 BH3-mimetic drugs elicit cell death of neuroendocrine tumours in preclinical models – An emerging therapeutic strategy for NETs

Introduction: There is an unmet clinical need to identify new, effective therapies for patients with neuroendocrine tumours (NETs). Analysis of single-cell expression data revealed that NETs express high levels of the Bcl2 family of antiapoptotic proteins. Therefore, we hypothesised that proapoptotic drugs, such as BH3-mimetics, can induce programmed cell death, i.e., apoptosis, of neuroendocrine cancer cells.

#4164 Diagnostic work-up for neuroendocrine tumors of occult primary at diagnosis: A retrospective monocentric study of 60 cases

Introduction: Neuroendocrine tumors (NET) are sometimes diagnosed with an occult primary. Identifying the primary and ruling-out unknown primary NET (NET-UP) has therapeutic implications.

#4141 BRAF/MEK combination treatment in a patient with BRAF mutated neuroendocrine carcinoma

Introduction: Preclinical studies indicate that BRAF V600E mutation is a druggable target in neuroendocrine carcinomas (NEC). Indeed, there are a few case reports that describe clinical response from BRAF inhibitor treatment of colorectal NEC.

#4090 Octreotide infusion pump in patients with functional neuroendocrine tumors and refractory hormonal syndromes

Introduction: In patients with metastatic functional neuroendocrine tumors (NETs), symptoms are, sometimes, not adequately controlled with long-acting somatostatin analogues (LASSAs), so patients need to use boost subcutaneous (sc) octreotide injections (inj) daily. However, this approach is not always effective and convenient for the patients.
