Neuroendocrine tumours are a heterogeneous group of tumours that arise in diverse anatomical locations and vary greatly in behavior and response to treatment. A biomarker is a characteristic that can be objectively measured and evaluated as an indicator of a pathogenic process or response to treatment. Biomarkers can be diagnostic, prognostic, predictive or surrogate markers of clinical endpoints. The management of neuroendocrine tumours has changed dramatically with the intro...

Introduction: Glucagonomas are rare functional pancreatic neuroendocrine tumours (p NETs), with an annual occurrence of 0.01 to 0.1 new cases per 100,000. Objective: We focused on presenting symptoms, primary’s size and location, presence of metastases, biomarkers at diagnosis, histology, response to first line treatment (clinical and biochemical), disease fee survival (DFS) and PFS (progression free survival). Methods: Eighteen pa...

Background: 177Lu-DOTATATE is increasingly used in patients with advanced neuroendocrine tumour (NET). However, few circulating biomarkers are available to predict progression-free survival (PFS) of patients received 177Lu-DOTATATE.Materials and methods: Clinicopathological data and data of baseline circulating biomarkers including neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), lymphocyte-monocyte ratio (LMR), e...

Background: The incidence of neuroendocrine neoplasms (NENs) in younger populations (<50 years) is increasing and was 1.8 per 100,000 persons in 2011. There is limited data on NENs and pregnancy.Methods: A retrospective analysis was performed on pregnant women with NENs managed in an ENETS Centre of Excellence. The objectives of the study were to describe the tumour characteristics, pregnancy outcomes, treatment and the tumour behaviour intra-pregnan...

Introduction: High doses/frequency of somatostatin analogues (SSA) are often used to control refractory functional symptoms and/or tumour progression in patients treated with standard doses of SSAs, but there is limited evidence for the efficacy of this strategy.Methods: Retrospective analysis of 47 NET patients on lanreotide Autogel 120 mg every 3 weeks (as monotherapy). Progression-free survival (PFS) and clinical outcomes were assessed. A 30% change i...

Introduction: Escalated doses of octreotide LAR are commonly used to control functional symptoms and/or tumour growth, but there is limited evidence regarding the efficacy of this approach.Methods: Retrospective analysis of 69 NET patients treated with octreotide LAR 30 mg every 3 weeks (as monotherapy). Progression-free survival (PFS) and clinical outcomes were assessed. A 30% change in symptomatology and biomarker levels was considered significant....

Background: Bone metastases have been described in up to 15% of patients with NETs and are associated with a worse clinical outcome. Here we investigate the role of CTCs as a marker of bone metastases in a large cohort of patients with gastroenteropancreatic NETs.Methods: To be eligible for the study, patients were required to be ≥ 18 years old, have histologically confirmed midgut or pancreatic NET (pNET) and metastatic disease measurable by RECIS...

Background: Gastrointestinal (GI) neuroendocrine tumours (NETs) are potentially malignant lesions originating from the enterochromaffin cells of the GI tract. These neoplasms often produce characteristic hormonal syndromes and can cause debilitating symptoms. Endoscopic submucosal dissection (ESD) is a well-established, complex, endoscopic technique, which allows for full resection of the mucosal and submucosal lesions without the need for open surgery.M...

Background: Although small bowel (SB) neuroendocrine tumours (SBNETs) often present as indolent lesions, late diagnosis may result in poor outcomes. Successful management is therefore dependent on early identification. Double-balloon enteroscopy (DBE) enables direct SB mucosal visualisation, sampling and endotherapy. Our aim was to evaluate the role of DBE for early diagnosis and management of SBNETs.Methods: Retrospective review of all SBNETs diagnosed/...

Introduction: Phaeochromocytomas and paragangliomas (PPGL) are rare neuroendocrine tumours with no standardised protocol for treatment. 177Lu-DOTATATE peptide receptor radionuclide therapy (PRRT) is an emerging treatment option for patients with metastatic and/or inoperable PPGL, and with low toxicity. We present our experience with PRRT in advanced PPGL, treated in a ENETS Centre of Excellence.Materials and Methods: 165 patients with...
