The number of people diagnosed and living with cancer in the UK continues to rise and this also places increasing demands on specialist cancer care services (NHS England 2015). Neuroendocrine Tumours (NETs) incidence and prevalence increases alongside this demand (PHE 2016). NETs still remain a rare cancer with specialist needs and the clinical nurse specialist (CNS) team are ideally placed to support these patients. Oncology clinics are becoming increasingly pressured and the...

Introduction: Neuroendocrine tumours (NET) are a diverse group of neoplasms originating from cells within the diffuse endocrine system. Urine 5-HIAA is commonly used in the diagnosis and monitoring of patients with NET in particular small intestinal neuroendocrine tumour with carcinoid syndrome. Urine 5-HIAA collection over a 24 hour period and the potential exposure to acid preservative in the sample container, limit the use of urine 5-HIAA.Methods: Sam...

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...

Olfactory neuroblastoma (ONB) is a rare neuroendocrine tumour with a slow onset of symptoms, and classically a propensity for recurrence and a poor prognosis. Due to its rarity, there is no agreed standard therapy, but treatment will usually include surgical resection, adjuvant radiotherapy and/or chemotherapy. However, such tumours very often show positive uptake on somatostatin receptor radionuclide scanning, and selective use of peptide receptor radionuclide therapy (PRRT) ...

Background: CALM-NET (EudraCT 2013-002194-22; NCT02075606), a prospective, exploratory study, evaluated enumeration of pre-treatment circulating tumour cells as a predictor of symptomatic response to lanreotide autogel (LAN) in patients with functional midgut neuroendocrine tumours (NETs). Here, we describe the effect of LAN on biomarkers.Methods: Patients, ≥18 years, with functional, well- or moderately-differentiated midgut NETs were treated with...

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: Transplantation for cancer indications is evolving rapidly in UK and Ireland. Liver transplantation [LT] for unresectable neuroendocrine tumour liver metastases [NET LM] is one of three new cancer indications. It has the potential to significantly improve survival outcomes however, transplant benefit has likely been achieved only by highly experienced Centre(s). Since eligible patients for transplantation also have excellent prognosis with standard management, care...
