Abstract
A literature search of MEDLINE/PUBMED was conducted with the aim to highlight current endoscopic management of localised gastro-entero-pancreatic NETs. Relevant articles were identified through a manual search, and reference lists were reviewed for additional articles. The results of the research have been displayed in a narrative fashion to illustrate the actual state-of-the-art of endoscopic techniques in the treatment of NETs. Localised NETs of the stomach, duodenum and rectum can benefit from advanced endoscopic resection techniques (e.g., modified endoscopic mucosal resection, endoscopic full thickness resection, endoscopic submucosal dissection) according to centre expertise. Radiofrequency thermal ablation can be proposed as an alternative to surgery in selected patients with localised pancreatic NETs.

Abstract
5-hydroxyindole acetic acid, a metabolite of serotonin, is used in the diagnosis and monitoring of patients with neuroendocrine tumours, in particular patients with small intestinal neuroendocrine tumours associated with the carcinoid syndrome. Analysis of 5-hydroxyindole acetic acid was commonly performed in urine, but blood-based assays are now becoming available. The objective of this study was to assess how 5-hydroxyindole acetic acid compares in plasma and serum as a biochemical marker of neuroendocrine tumours. Twenty-four-hour urine, plasma and serum samples were obtained from 80 patients with neuroendocrine tumours and 30 healthy volunteers. We developed a liquid chromatography tandem mass spectrometry assay for plasma and serum 5-hydroxyindole acetic acid. Comparison was made between them, and their cut-off was determined using a receiver-operating characteristic curve. A close correlation was shown between plasma and serum 5-hydroxyindole acetic acid. At a cut-off of 135 nmol/l, a sensitivity of 91.2% with a specificity of 61.9% was obtained for both compared to the urinary assay. A statistically significant agreement was shown when plasma and serum 5-hydroxyindole acetic acid were compared with the currently used urine assay in patients with neuroendocrine tumours; κ = 0.675 (95% CI 0.49 to 0.86), p < 0.001 and healthy volunteers; 0.967 (95% CI 0.828 to 0.999), p = <0.001. In conclusion, 5-hydroxyindole acetic acid in plasma and serum were comparable, hence either sample type can be used interchangeably.

Abstract
Small intestinal neuroendocrine tumours (SI-NETs) are the most common small intestinal tumours. A particularly challenging subset of these tumours is those that involve the superior mesenteric artery or vein for which the role and feasibility of surgery are often questioned. This systematic review aimed to identify and evaluate the management strategies used for these complex SI-NETs. The identified studies showed positive outcomes with surgery and multimodality therapy.

Abstract
Aim: The RAISE project aimed to find a surrogate end point to predict treatment response early in patients with enteropancreatic neuroendocrine tumors (NET). Response heterogeneity, defined as the coexistence of responding and non-responding lesions, has been proposed as a predictive marker for progression-free survival (PFS) in patients with NETs. Patients & methods: Computerized tomography scans were analyzed from patients with multiple lesions in CLARINET (NCT00353496; n = 148/204). Cox regression analyses evaluated association between response heterogeneity, estimated using the standard deviation of the longest diameter ratio of target lesions, and NET progression. Results: Greater response heterogeneity at a given visit was associated with earlier progression thereafter: week 12 hazard ratio (HR; 95% confidence interval): 1.48 (1.20-1.82); p < 0.001; n = 148; week 36: 1.72 (1.32-2.24); p < 0.001; n = 108. HRs controlled for sum of longest diameter ratio: week 12: 1.28 (1.04-1.59); p = 0.020 and week 36: 1.81 (1.20-2.72); p = 0.005. Conclusion: Response heterogeneity independently predicts PFS in patients with enteropancreatic NETs. Further validation is required.

Abstract
Aim: The RAISE project assessed whether deep learning could improve early progression-free survival (PFS) prediction in patients with neuroendocrine tumors. Patients & methods: Deep learning models extracted features from CT scans from patients in CLARINET (NCT00353496) (n = 138/204). A Cox model assessed PFS prediction when combining deep learning with the sum of longest diameter ratio (SLDr) and logarithmically transformed CgA concentration (logCgA), versus SLDr and logCgA alone. Results: Deep learning models extracted features other than lesion shape to predict PFS at week 72. No increase in performance was achieved with deep learning versus SLDr and logCgA models alone. Conclusion: Deep learning models extracted relevant features to predict PFS, but did not improve early prediction based on SLDr and logCgA.

Abstract
AIM The aim of this study was to assess the efficacy and safety of 177Lu-DOTATATE in patients with neuroendocrine tumors (NETs) and extensive bone metastases, that is, more than 50% of the skeleton involved. METHOD A single-center retrospective analysis was performed in 30 patients (13 women and 17 men, mean age, 60 years; range, 35-77 years) undergoing 177Lu-DOTATATE therapy. Patients had progressive metastatic NETs with extensive skeletal metastases (>50% skeletal involvement seen on baseline 68Ga-DOTATATE PET/CT). The average administered activity was 7.308 (SD, 0.02) GBq per cycle with average treatment interval of 15 weeks. Survival analyses (progression-free survival [PFS], overall survival), radiological response assessment, toxicity assessment, and health-related quality of life (QoL) was performed. RESULTS Overall, 26 patients completed 4 cycles, and 4 patients had less than 4 cycles of 177Lu-DOTATATE. One patient (3%) did not complete treatment because of hematological toxicity. The estimated median PFS and median overall survival were calculated at 27 and 35 months, respectively. End-of-treatment radiological assessment showed partial response in 5 patients (17%), stable disease in 20 patients (66%), and radiological progressive disease in 3 patients (10%). Clinical progression was seen in a further 2 patients (7%).The incidence of grade 3/4 bone marrow toxicity was 10%. No patient had grade 3/4 peptide receptor radionuclide therapy-related nephrotoxicity. There was overall improvement in global QoL score (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Gastrointestinal NET-21) (P = 0.019). CONCLUSION 177Lu-DOTATATE seems to have satisfactory therapeutic outcome in patients with advanced metastatic NET with extensive bone disease, with reasonable PFS and significant improvement in the global health-related QoL. The bone marrow toxicity was within the accepted range. Increasing the interval between cycles does not seem to reduce efficacy and may reduce toxicity, ensuring the bone marrow has sufficient time to recover between cycles.

Abstract
The aim of this study was to evaluate the efficacy and safety of 177 Lu-DOTATATE therapy in advanced metastatic disease. A retrospective analysis of 395 patients (180 female, 215 males, mean age 62) with progressive metastatic neuroendocrine tumours (NETs) who were treated with 177 Lu-DOTATATE was performed. Overall, 115 patients had less than four cycles and 280 completed four cycles of treatment. Progression-free survival (PFS) and overall survival (OS) was performed using Kaplan-Meier analysis. Analysis of survival predictors was performed using Cox regression model. Toxicity was defined using the Common Terminology Criteria for Adverse Events version 5 (CTCAE 5.0). The percentage of patients with liver and skeletal metastases were 91 and 57%, respectively. Median PFS and OS were calculated at 33 months (95% CI: 29-37 months) and 46 months (95% CI: 48-56 months), respectively. End of treatment response assessment was performed using cross sectional imaging demonstrated partial response in 22%, stable disease in 64% and progressive disease in 14% of patients. Overall, grade 3 and 4 bone marrow toxicity was seen in 8%. One patient (0.3%) developed irreversible grade 4 nephrotoxicity. Myelodysplastic disease was recorded in one patient (0.3%). Univariate analysis of PFS predictors showed that body mass index (BMI), baseline chromogranin A (CgA) >400 ng/l, baseline alkaline phosphatase (ALP) >130 mg/dl, liver tumour volume and overall tumour burden were significant. On multivariate analysis only Ki67, high CgA and low BMI retained significance. 177 Lu-DOTATATE is an effective treatment in advanced NETs with generally high-volume metastases. It is well-tolerated. Ki-67, CgA and BMI appear to be predictors for PFS.

Abstract
Purpose of Review Mesenteric desmoplasia in small intestinal neuroendocrine neoplasms (SINENs) is associated with increased morbidity and mortality. In this paper, we discuss the development of desmoplasia in SINENs. Recent Findings The fibrotic reactions associated with these tumours could be limited to the loco-regional environment of the tumour and/or at distant sites. Mesenteric fibrotic mass forms around a local lymph node. Formation of desmoplasia is mediated by interactions between the neoplastic cells and its microenvironment via number of profibrotic mediators and signalling pathways. Profibrotic molecules that are mainly involved in the desmoplastic reaction include serotonin, TGFβ (transforming growth factor β) and CTGF (connective tissue growth factor), although there is some evidence to suggest that there are a number of other molecules involved in this process. Summary Desmoplasia is a result of autocrine and paracrine effects of multiple molecules and signalling pathways. However, more research is needed to understand these mechanisms and to develop targeted therapy to minimise desmoplasia.

Abstract
Pancreatic neuroendocrine tumours (panNET) are heterogeneous neoplasms usually characterised by slow growth and secretion of hormones, which often cause symptoms. The effect of these symptoms on quality of life (QoL) has not previously been examined in detail. EORTC (European Organisation for Research and Treatment of Cancer) guidelines were followed in phases 1-3 to produce a potential module of questions usable for trials in panNET, focusing on three common types of panNET. For two less common types, a list of symptoms was constructed. Following an extensive literature search and phase 1a interviews with patients and healthcare workers, a long list of potential issues (169) was obtained. This list was shown to 12 patients from three countries in phase 1b interviews to check that no items were missed. The list was reduced to 57 issues. The list of issues was converted to questions, mainly from existing validated questions within the EORTC item library. The list of questions was then used in a phase 3 international study in eight countries using seven languages. A provisional module of 24 items is presented for use in nonfunctioning panNET, gastrinoma and insulinoma. This module increases knowledge concerning QoL in this condition and may be a useful adjunct in clinical trials. A phase 4 trial is being considered for validation of this questionnaire.

Abstract
Purpose: To assess efficacy and safety of 177Lu-DOTATATE in patients with neuroendocrine tumours (NETs) with reduced renal function i.e., eGFR below 60 ml/min/1.73 m2. Methods: A single-centre retrospective analysis was performed in 33 patients with eGFR less than 60 ml/min/1.73 m2. Of these 33 patients, 26 patients had chronic kidney disease (CKD) stage 3a (eGFR between 45-60 ml/min/1.73 m2) and 7 patients had CKD stage 3b (eGFR between 30-45 ml/min/1.73 m2). Renal toxicity and temporal changes in eGFR were recorded. Association of potential risk factors and any kidney function deterioration (>10% reduction of eGFR) was evaluated. Survival, radiological response assessment and quality of life data was collected. Results: The incidence of permanent grade 3/4 nephrotoxicity was 3% (single patient with grade 4 nephrotoxicity). The mean annual reduction of eGFR estimated at 2.5%. Permanent decline of >10% eGFR of any grade was recorded in 45% of patients (n = 15). Nine patients moved into higher CKD categories (eight patients who moved from CKD 3a to CKD 3b and one patient who moved from CKD3b to CKD 5). No significant relationship was found between renal risk factors and permanent reduction of renal function. Grade 3/4 bone marrow toxicity was observed in 9% of patients. The estimated median progression-free survival (PFS) was 42 months and median overall survival (OS) was 47 months. At the end of the treatment, the radiological assessment showed partial response in 33%, stable disease in 55%, and progressive disease in 12%. There was an improvement in global quality of life and endocrine score (EORTC QLQ-GI-NET21) (p value: 0.046 and 0.041 respectively). Conclusion: 177Lu-DOTATATE appears to be generally well-tolerated in patients with pre-existing CKD stage 3 with a low incidence of permanent major nephrotoxicity. 177Lu-DOTATATE appears to have a good therapeutic effect; with most patients reporting improvement in quality of life.

Abstract
177Lu-Dotatate is increasingly used in patients with advanced neuroendocrine tumour (NET). However, few prognostic markers are available to stratify progression-free survival (PFS) of patients who received 177Lu-Dotatate. Clinicopathological data including baseline circulating biomarkers of patients with advanced NET who received 177Lu-Dotatate were routinely collected and were retrospectively analysed. Continuous variables were normalized by dividing them by their upper normal limits. The whole data set was randomly divided into a training set and a validation set. Univariate and multivariate logistic regression analyses were used to identify independent markers and to develop a scoring model to predict treatment failure at 1 year. In total, 195 patients were included. Elevated baseline chromogranin A (CgA), normal creatinine and previous chemotherapy were three risk factors independently associated with 1-year treatment failure. By combining these risk factors, a scoring model was developed which could accurately predict 1-year treatment failure both in the training set (area under curve, AUC, 0.813; 95% CI, 0.731-0.895; P< 0.001) and in the validation set (AUC, 0.816; 95% CI, 0.644-0.968; P< 0.001). After selecting a score of 29.7 as the cut-off value of the scoring model, patients could be stratified into two groups namely low-risk and high-risk with significantly different 1-year treatment failure rate, PFS and overall survival (OS; P< 0.001) both in the training set and validation set. In conclusion, baseline CgA, creatinine level and previous chemotherapy were independently associated with 1-year treatment failure of patients with advanced NET who received 177Lu-Dotatate and the scoring model and prognostic stratification based on these markers could accurately predict 1-year treatment failure, PFS and OS.

Abstract
PURPOSE Type III gastric neuroendocrine neoplasms (g-NENs) have historically been regarded as aggressive tumours, hence current guidelines advocate radical surgery with lymph node dissection. Data on the roles of endoscopic or less extensive surgical resections are more limited. The aim of our study is to evaluate the clinicopathological features and long-term outcomes of patients undergoing endoscopic or limited surgical resection for localised grade 1 or 2 type III g-NENs when compared to radical surgery. METHODS Retrospective analysis of all patients diagnosed with a localised grade 1 or 2 type III g-NENs across six tertiary NEN centers between 2006 and 2019. RESULTS Forty-five patients were diagnosed with a potentially resectable grade 1 or 2 type III g-NEN of whom 36 underwent either endoscopic or surgical resection. No statistically significant differences were found between the three resection groups in terms of patient age, tumour location, grade or size. Only tumour size was found to be significantly associated with poor clinical outcome (p = 0.012) and ROC curve analysis identified tumour size >10 mm as a negative predictor (AUC:0.8030, p = 0.0021). Tumours >10 mm were also more likely to be associated with lymph node metastases on imaging and histology (p = 0.039 and p = 0.026 respectively). CONCLUSIONS Localised grade 1 or 2 type III g-NENs had a good prognosis in this series. Tumour size >10 mm was the most significant prognostic factor affecting patient outcome. Endoscopic resection or limited surgical resection is feasible and safe in small type III g-NENs which demonstrate favourable grade 1/2, well differentiated histology.

Abstract
PURPOSE The safety and efficacy of 177Lu-DOTATATE in older patients with advanced neuroendocrine tumours (NET) are not well understood. METHODS Patients ≥70 years of age and treated with 177Lu-DOTATATE were included. Toxicity, health-related quality of life (HRQoL), objective response, progression-free survival (PFS) and overall survival (OS) were assessed. The relationship between baseline characteristics and PFS and OS was analysed using the Kaplan-Meier method. Univariate analyses were performed using the Cox proportional hazards model. RESULTS In total, 71 patients were included (76.1% midgut primary). The median age at diagnosis and age at 177Lu-DOTATATE treatment were 70 and 74 years, respectively. The majority (78.9%) of patients completed 4 cycles of 177Lu-DOTATATE. Clinically significant myelosuppression was rare (2.8%). There was no deterioration in HRQoL and 'disease-specific worries' significantly improved (P = 0.029). Radiological response assessment was available in 66 patients. Partial response, stable disease and progression of disease were found in 10 (15.2%), 52 (78.8%) and 4 patients (6.1%), respectively. Median PFS and OS were 36.0 and 47.0 months, respectively. Increased baseline alkaline phosphatase was associated with poorer PFS (P = 0.002) and OS (P = 0.006). CONCLUSION Patients ≥70 years of age with advanced NET treated with 177Lu-DOTATATE have efficacy and toxicity profiles similar to the wider NET population, without deterioration of HRQoL.

Abstract
OBJECTIVES There is a pressing need to develop clinical management pathways for grade 3 (G3) gastroenteropancreatic neuroendocrine neoplasms (GEP NEN). METHODS We performed a retrospective study on patients with metastatic G3 GEP NEN. The relationship between baseline characteristics and progression-free survival and overall survival was analyzed using the Kaplan-Meier method. Univariate and multivariate analyses were performed using the Cox proportional hazards model. RESULTS We included 142 patients (74 well-differentiated neuroendocrine tumors [WDNETs], 68 poorly differentiated neuroendocrine carcinomas [PDNECs]). Patients with WDNET had prolonged survival compared with PDNEC (median, 24 vs 15 months, P = 0.0001), which persisted in both pancreatic and nonpancreatic cohorts. Well-differentiated morphology, Ki-67 <50% and positive somatostatin receptor imaging were independently associated with prolonged survival. Of the subgroup treated with first-line platinum-based chemotherapy, response rates were favorable (partial response, 47%; stable disease, 30%); there was no significant difference in response rates nor progression-free survival between WDNET and PDNEC despite significantly prolonged overall survival in the WDNET cohort. CONCLUSIONS Our study corroborates the knowledge of 2 prognostically distinct subgroups within the World Health Organization 2019 G3 GEP NEN population, observed in both pancreatic and nonpancreatic gastrointestinal cohorts. Definitive management pathways are needed to reflect the differences between G3 WDNET and PDNEC.

Abstract
BACKGROUND Circulating tumor cells (CTCs) are detectable in patients with neuroendocrine tumors (NETs) and are accurate prognostic markers although the optimum threshold has not been defined. OBJECTIVE This work aims to define optimal prognostic CTC thresholds in PanNET and midgut NETs. PATIENTS AND METHODS CellSearch was used to enumerate CTCs in 199 patients with metastatic pancreatic (PanNET) (90) or midgut NETs (109). Patients were followed for progression-free survival (PFS) and overall survival (OS) for a minimum of 3 years or until death. RESULTS The area under the receiver operating characteristic curve (AUROC) for progression at 12 months in PanNETs and midgut NETs identified the optimal CTC threshold as 1 or greater and 2 or greater, respectively. In multivariate logistic regression analysis, these thresholds were predictive for 12-month progression with an odds ratio (OR) of 6.69 (P < .01) for PanNETs and 5.88 (P < .003) for midgut NETs. The same thresholds were found to be optimal for predicting death at 36 months, with an OR of 2.87 (P < .03) and 5.09 (P < .005) for PanNETs and midgut NETs, respectively. In multivariate Cox hazard regression analysis for PFS in PanNETs, 1 or greater CTC had a hazard ratio (HR) of 2.6 (P < .01), whereas 2 or greater CTCs had an HR of 2.25 (P < .01) in midgut NETs. In multivariate analysis OS in PanNETs, 1 or greater CTCs had an HR of 3.16 (P < .01) and in midgut NETs, 2 or greater CTCs had an HR of 1.73 (P < .06). CONCLUSIONS The optimal CTC threshold to predict PFS and OS in metastatic PanNETs and midgut NETs is 1 and 2, respectively. These thresholds can be used to stratify patients in clinical practice and clinical trials.

Abstract
Aim Analysis of the pathophysiology of mesenteric fibrosis (MF) in small intestinal neuroendocrine tumors (SI-NETs) in an in vitro paracrine model and in human SI-NET tissue samples. Methods An indirect co-culture model of SI-NET cells KRJ-I and P-STS with stromal cells HEK293 was designed to evaluate the paracrine effects on cell metabolic activity, gene expression by RT2 PCR Profilers to analyse cancer and fibrosis related genes, and RNA sequencing. The integrin signaling pathway, a specific Ingenuity enriched pathway, was further explored in a cohort of human SI-NET tissues by performing protein analysis and immunohistochemistry. Results RT Profiler array analysis demonstrated several genes to be significantly up- or down-regulated in a cell specific manner as a result of the paracrine effect. This was further confirmed by employing RNA sequencing revealing multiple signaling pathways involved in carcinogenesis and fibrogenesis that were significantly affected in these cell lines. A significant upregulation in the expression of various integrin pathway – related genes was identified in the mesenteric mass of fibrotic SI-NET as confirmed by RT-qPCR and immunohistochemistry. Protein analysis demonstrated downstream activation of the MAPK and mTOR pathways in some patients with fibrotic SI-NETs. Conclusion This study has provided the first comprehensive analysis of the crosstalk of SI-NET cells with stromal cells. A novel pathway – the integrin pathway – was identified and further validated and confirmed in a cohort of human SI-NET tissue featured by a dual role in fibrogenesis/carcinogenesis within the neoplastic fibrotic microenvironment.

Abstract
BACKGROUND Cardiac metastases (CM) from neuroendocrine tumours (NET) are rare; however, with the introduction of new molecular imaging modalities, such as 68Ga-DOTATATE PET-CT for NET diagnosis and re-staging, they are now identified more frequently. This study presents a single-institution experience on the NET CM characteristics, management, and prognostic implications. METHODS Between January 1998 and January 2020, 25 NET patients with CM were treated in our unit. A retrospective review of electronic records was performed. Overall survival (OS) was assessed by the Kaplan-Meier method. Cox regression models were used to evaluate the association of various clinical variables with OS. RESULTS The median age in the NET CM cohort was 64 years, with small intestine being the most common primary (84%). Nearly half of the patients suffered either from shortness of breath (48%) or had palpitations (12%). Peptide receptor radionuclide therapy (PRRT) was applied in more than half of the patients (64%), who had an improved trend for a longer median OS compared to those patients who did not receive PRRT (76.0 vs. 14.0 months, p = 0.196). The multivariate analysis demonstrated that concomitant skeletal or pancreatic metastases, as well as N-terminal pro-B-type natriuretic peptide (NT pro-BNP) >2 × upper limit of normal (ULN), were independent poor prognosticators. CONCLUSIONS Clinical features of NET CM ranged from asymptomatic patients to heart failure. Concomitant bone or pancreatic metastases and NT pro-BNP levels >2 ULN predicted shorter survival time. PRRT serves as a feasible therapy with promising survival benefits; however, more data are needed.

Abstract
BACKGROUND Above-label doses of somatostatin analogs (SSAs) are increasingly utilized in the management of inoperable/metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs), progressing on standard 4-weekly regimens. OBJECTIVE To evaluate the antiproliferative effect of 3-weekly SSA administration in a retrospective GEP-NET cohort. METHODS Patients with advanced GEP-NET, treated with long-acting release (LAR) octreotide 30 mg or lanreotide Autogel 120 mg at a 3-weekly interval, after disease progression on standard 4-weekly doses, were retrospectively identified. Clinicopathologic and treatment response data were collected. Progression-free survival (PFS; dose escalation to radiographic progression or death) was estimated with the Kaplan-Meier method. Factors associated with PFS were identified with the Cox proportional-hazards model. RESULTS The inclusion criteria were fulfilled by 105 patients. Octreotide LAR was administered to 60 (57%) and lanreotide Autogel to 45 (43%). Indications for dose escalation were breakthrough carcinoid symptoms (58%), radiographic progression (35%) and/or increasing biomarkers (11%). Diarrheal and/or flushing symptomatic improvement was identified in 37/67 cases (55%) and 30/55 cases (55%) with available data, respectively. The disease control rate (radiographic partial response or stable disease) was achieved in 53 patients (50%). Median PFS was 25.0 months (95% CI 16.9-33.1). Patients with radiographic progression <12 months from 4-weekly SSA initiation had worse PFS after dose escalation (7.0 vs. 17.0 months, p = 0.002). In multivariate analysis, pancreatic NETs, a Ki-67 index ≥5% and multiple extrahepatic metastases were independently associated with inferior PFS. CONCLUSIONS Above-label doses of SSAs may offer a considerable prolongation of PFS and could be utilized as a bridge to other more toxic treatments. Patients with small bowel/colorectal primaries, a Ki-67 index <5% and absence of/limited extrahepatic metastases are more likely to benefit from this approach.

Abstract
BACKGROUND The number of therapeutic options for patients with pancreatic neuroendocrine neoplasms (PNEN) has increased, but the optimal therapeutic algorithm has not been defined due to lack of randomised trials comparing different modalities. METHODS We performed a retrospective study in patients with metastatic PNEN treated with ≥1 line of systemic therapy. The relationship between baseline characteristics, treatment type, and time to treatment failure (TTF), time to progression (TTP), and overall survival (OS) was analysed using the Kaplan-Meier method. Univariate and multivariate analyses were performed using the Cox proportional hazards model. RESULTS Two hundred and fifty-five patients with metastatic PNEN had 491 evaluable lines of therapy. Independent predictors of TTF included treatment type, Ki-67, tumour grade, and chromogranin A. To reduce selection bias, a subgroup of 114 patients with grade 2 (G2) metastatic pancreatic neuroendocrine tumours (PNET) was analysed separately. These patients had received 234 lines of treatment (105 chemotherapy, 82 molecular targeted therapy, and 47 peptide receptor radionuclide therapy [PRRT]). In the G2 cohort, TTF and TTP were superior for PRRT compared with both chemotherapy and molecular targeted therapy. OS in the G2 cohort was also superior for those that had received PRRT compared with those that had not (median 84 vs. 56 months; HR 0.55, 95% CI: 0.31-0.98, p = 0.04). CONCLUSIONS This study suggests that PRRT is associated with superior clinical outcomes relative to other systemic therapies for G2 metastatic PNET. Prospective studies are required to confirm these observations.

Abstract
The role of total parenteral nutrition (TPN) in cancer patients is controversial, but it may be a treatment option for some patients with indolent but advanced small intestinal neuroendocrine neoplasms (SI-NENs). The aim of this study is to investigate whether home TPN was associated with long-term survival and to assess the indications, duration and complications of TPN in patients with advanced SI-NENs. Patients with advanced SI-NENs who received home TPN were retrospectively included. Electronic records were reviewed for clinical information. Five patients receiving home TPN were identified out of 1011 patients with SI-NENs in our center. The median duration of TPN administration was 12 mo. Small bowel obstruction was the most common reason for TPN initiation. TPN-related complications included two catheter infections, one thrombosis and one episode of TPN-related transaminitis. At the last follow-up, three patients had died and two were alive. The median survival was 12 mo. Overall estimated 1-yr probability of survival on home TPN by Kaplan-Meier analysis was 40%. In conclusion, home TPN may be a treatment option in highly selected advanced SI-NEN patients with severe gastrointestinal tract dysfunction. The initiation of home TPN is associated with long-term survival (≥1 yr), and complication rates appear acceptable.

Abstract
PURPOSE Surgical resection is the only effective curative strategy for small intestinal neuroendocrine neoplasms (SINENs). Nevertheless, the evaluation of residual disease and prediction of disease recurrence/progression remains a problematic issue. METHODS We evaluated 13 SINENs that underwent surgical resection of the primary tumour and/or mesenteric mass. Patients were divided in three groups: (a) Group 1: SINENs that underwent resection with curative intent, (b) Group 2: SINENs treated with resection in the setting of metastatic disease, which remained stable and (c) Group 3: SINENs treated with resection in the setting of metastatic disease, with evidence of any progression at follow-up. NETest and chromogranin A were measured pre-operatively and post-operatively during a 22-month median follow-up period and compared with imaging studies. NETest score <20% was determined as normal, 20-40% low, 41-79% intermediate and ≥80% high score. RESULTS NETest score was raised in all (100%) SINENs pre-operatively. Surgery with curative intent resulted in NETest score reduction from 78.25 ± 15.32 to 25.25 ± 1.75 (p < 0.05). Low NETest scores post-operatively were evident in all cases without clinical evidence of residual disease (Group 1). However, the low disease activity score suggested the presence of microscopic residual disease. In three cases (75%) with stable disease (Group 2) the NETest score was low consistent with indolent disease. In the progressive disease group (Group 3), a high NETest score was present in three cases (60%) and an intermediate NETest score in the remainder (40%). CONCLUSIONS Blood NETest scores accurately identified SINENs and were significantly decreased by curative surgery. Monitoring NETest post-operatively may facilitate management by identifying the presence of residual/progressive disease.

Abstract
PURPOSE Mesenteric fibrosis (MF) in small intestinal neuroendocrine neoplasms (SINENs) is often associated with significant morbidity and mortality. The detection of MF is usually based on radiological criteria, but no previous studies have attempted a prospective, multidimensional assessment of mesenteric desmoplasia to determine the accuracy of radiological measurements. There is also a lack of non-invasive biomarkers for the detection of image-negative MF. METHODS A multidimensional assessment of MF incorporating radiological, surgical and histological parameters was performed in a prospective cohort of 34 patients with SINENs who underwent primary resection. Pre-operative blood samples were collected in 20 cases to evaluate a set of five profibrotic circulating transcripts-the "fibrosome"-that is included as an "omic" component of the NETest. RESULTS There was a significant correlation between radiological and surgical assessments of MF (p < 0.05). However, there were several cases of image-negative MF. The NETest-fibrosome demonstrated an accuracy of 100% for the detection of microscopic MF. CONCLUSIONS The detection of MF by radiological criteria has limitations. The NETest-fibrosome is a promising biomarker for fibrosis detection and further validation of these results would be needed in larger, multicentre studies.

Abstract
PURPOSE Neuroendocrine neoplasms (NENs) may rarely metastasise to the orbit. Published data on epidemiology, incidence and preferred treatment is limited. We present the largest cohort of symptomatic and asymptomatic NEN patients with orbital metastases and data on epidemiological parameters, symptoms as well as diagnostic/treatment modalities used. METHODS We identified patients from our internal NEN database of patients who had also undergone Gallium68-DOTATATE PET (Ga68-DOTA). The diagnosis of orbital metastatic NEN was made on somatostatin receptor imaging and confirmed on a dedicated MRI of orbits. RESULTS We identified 27 patients of 994 patients evaluated with Ga68-DOTATATE PET imaging during their surveillance monitoring in our department; 15 female, average age at NEN diagnosis 53 years and orbital metastatic NEN diagnosis 59 years. The majority of NEN primaries originated from small bowel (18/27, 66.4%) or pancreas 4/27 (4/27, 14.8%). Hepatic with or without concomitant skeletal metastases were present in 23/27 (85%) of patients. Ocular symptoms and/or signs were evident in 11/27 (41%) of patients. 5/11 symptomatic patients underwent external beam radiotherapy (EBRT) resulting in complete symptoms resolution. The 5-year survival was estimated at 84.1%. CONCLUSIONS Orbital metastases of NEN have a relatively low prevalence, more commonly associated with small bowel primary. Extraocular muscles are primarily affected, irrespectively of liver disease burden. Survival does not seem to be affected. EBRT is an efficacious treatment modality for both symptom relief and tumour growth control. Administration of peptide receptor radionuclide therapy may occasionally induce temporary ocular symptoms, which resolve following treatment with a short course of steroids.

Abstract
PURPOSE The antiproliferative properties of lanreotide autogel (LAN) in gastroenteropancreatic neuroendocrine neoplasms (GEP NENs) were demonstrated in the CLARINET study. However, there is limited literature regarding factors that affect progression-free survival (PFS) in patients with GEP NENs treated with LAN. METHODS We identified a total of 191 treatment-naive patients with advanced GEP NENs and positive SSTR uptake on imaging (Octreoscan or 68Gallium DOTATATE Positron Emission Tomography [68GaPET]) who received first-line LAN monotherapy, albeit at various starting doses (60, 90 or 120 mg/month). A group of 102 patients who initiated treatment at the standard dose of 120 mg/month were included in the study and further evaluated by univariate and multivariate analyses to identify predictors of PFS. RESULTS The location of tumour primary was in the small bowel in 63 (62%), pancreas in 31 (30%) and colon/rectum in 8 patients (8%). The tumours were well-differentiated, and the majority were grade 1 (52%), or 2 (38%). About 60% of cases had progressive disease at the time of treatment initiation. Most patients with available pretreatment nuclear medicine imaging (Octreoscan or 68Ga PET) had a Krenning score of 3 (44%) or 4 (50%). The median PFS for the entire cohort was 19 months (95% CI 12, 26 months). The univariate analysis demonstrated that grade 2 tumours, progressive disease at baseline and metastatic liver disease were associated with a significantly shorter PFS, while other evaluated variables did not affect PFS at a statistically significant level. However, at multivariate analysis only the tumour grade remained statistically significant. CONCLUSIONS The current study showed that, of many evaluated variables, only the tumour grade was predictive of PFS duration and this should be considered during patient selection for treatment.

Abstract
Background Bone metastases are associated with a worse outcome in patients with neuroendocrine tumours (NETs). Tumour overexpression of C-X-C chemokine receptor 4 (CXCR4) appears predictive of skeletal involvement. We investigated the role of circulating tumour cells (CTCs) and CXCR4 expression on CTCs as potential predictors of skeleton invasion. Methods Blood from patients with metastatic bronchial, midgut or pancreatic NET (pNET) was analysed by CellSearch. CXCR4 immunohistochemistry was performed on matched formalin-fixed paraffin-embedded (FFPE) samples. Results Two hundred and fifty-four patients were recruited with 121 midgut and 119 pNETs, of which 51 and 36% had detectable CTCs, respectively. Bone metastases were reported in 30% of midgut and 23% of pNET patients and were significantly associated with CTC presence (p = 0.003 and p < 0.0001). In a subgroup of 40 patients, 85% patients with CTCs had CTCs positive for CXCR4 expression. The proportion of CXCR4-positive CTCs in patients with bone metastases was 56% compared to 35% in those without (p = 0.18) it. Staining for CXCR4 on matched FFPE tissue showed a trend towards a correlation with CXCR4 expression on CTCs (p = 0.08). Conclusions CTC presence is associated with bone metastases in NETs. CXCR4 may be involved in CTC osteotropism and present a therapeutic target to reduce skeletal morbidity.

Abstract
Glucagonoma is an extremely rare, glucagon-secreting neuroendocrine tumor of the pancreas. Only sparse data are available about the characteristics of this tumor in somatostatin receptor imaging and only for the situation of initial diagnosis. We present a series of 3 glucagonoma patients who underwent at least 1 Ga-DOTATATE PET/CT scan. All patients were diagnosed by either histology and/or elevated serum levels of glucagon. The presented cases suggest that somatostatin receptor-based imaging can probably be used for re-evaluation of disease status in patients with glucagonoma in a similar way as it is already established for neuroendocrine tumors of other origin.

Abstract
BACKGROUND Small intestinal neuroendocrine tumours (SI NETs) represent 30-50% of small bowel neoplasms and often present at an advanced stage. To date, there is relatively limited literature regarding prognostic factors affecting overall survival (OS) in stage IV disease. In addition, the prevalence of mesenteric fibrosis (MF) in SI NETs and its effect on OS have not been sufficiently explored in the literature. AIM The primary aim of this study was to perform a large-scale survival analysis in an institutional cohort of 387 patients with metastatic (stage IV) SI NETs. The secondary aim was to provide epidemiological information regarding the prevalence of MF and to evaluate its effect on OS. RESULTS The median OS was 101 months (95% CI 84, 118). Age > 65 years, mesenteric metastases with and without desmoplasia, liver metastases, carcinoid heart disease (CHD) and bone metastases were associated with a significantly shorter OS, while primary tumour resection was predictive of a longer OS. The benefit of surgical resection was limited to symptomatic patients. MF was present in approximately 50% of patients with mesenteric lymphadenopathy. Elevated urinary 5-HIAA levels correlated strongly with the presence of CHD (p < 0.001) and to a lesser extent (p = 0.02) with MF. MF and CHD did not usually co-exist, suggesting that different mechanisms are likely to be involved in the development of these fibrotic complications. CONCLUSIONS This study has identified specific prognostic factors in a large cohort of 387 patients with advanced SI NETs and has provided useful epidemiological data regarding carcinoid-related fibrotic complications.

Abstract
BACKGROUND Small intestinal neuroendocrine tumours (SI NETs) represent 30-50% of small bowel neoplasms and are often associated with diverse fibrotic complications. Mesenteric fibrosis is a hallmark of SI NETs which may cause substantial morbidity and is considered an adverse feature. However, survival analyses in this group of patients are lacking. METHODS The aim of this retrospective study was to determine the overall survival (OS) and factors affecting prognosis in a large cohort of 147 patients with SI NETs and radiological evidence of mesenteric desmoplasia from our centre. The severity of desmoplasia was graded radiologically and its effect on OS and long-term complications was assessed. The median follow-up period was 82 months. RESULTS The median OS was 8.7 years (95% CI 6.8-9.9) with an overall 5-year survival of 71%. The univariate analysis demonstrated that an age >65 years, a liver tumour burden >50% of the hepatic parenchyma, carcinoid heart disease, chromogranin A levels >10 times the upper limit of normal, and urinary 5-hydroxyindoleacetic acid (5-HIAA) levels >5 times the upper limit of normal were poor prognosticators, while primary resection was associated with a longer OS. However, only an age >65 years and urinary 5-HIAA levels >10 times the upper limit of normal remained statistically significant after multivariate analysis. The severity of mesenteric desmoplasia did not seem to demonstrate a statistically significant relationship to OS or long-term outcomes. CONCLUSION This study is the first comprehensive survival analysis of patients with SI NETs associated with mesenteric desmoplasia and has provided important and clinically relevant epidemiological data for this group of patients.

Abstract
4090 Background: The efficacy of peptide-radiolabelled receptor targeted therapy (PRRT) in patients with well differentiated neuroendocrine tumours has been demonstrated in Phase II and Phase III studies. The recently completed phase IV NETTER-01 demonstrated disease stabilisation or partial response in approximately 80% of patients. However, more studies are needed to identify predictors of PRRT response. We sought to investigate the clinic-pathological characteristics in patients that had radiological progression or death within 12 months of completion of treatment with PRRT. Methods: We performed a retrospective analysis of all patients who had PRRT from 2011-2016. Patient with at least one year of follow-up data from the last treatment dose were included. Patients with evidence of radiological progression within one year of finishing treatment (Group 1) were compared to a similar group with disease stabilisation/response (Group 2)that were matched for age, grade, primary and distribution of metastases. The indication for PRRT was defined as either small volume progression ( < 20%) or progression by RECIST. Results: 307 patients underwent PRRT with Lu-177 or Y-90 DOTATATE during this period. 66 patients in Group 1 were compared to 64 patients in Group 2. There was a significant difference in median overall survival, Group 1 = 21 months compared to Group 2 = 35 months, (p < 0.002). A significantly higher proportion of patients in group 1 had more than 50% liver volume (p < 0.0001). Mean CgA was significantly higher in Group 1, 1250 pg/ml vs 608 pg/ml in Group 2 ( p < 0.03). 18 patients in Group 2 had small volume progression prior to treatment commencement compared to 6 in Group 1 (p < 0.003). Conclusions: Radiological progression within 12 months of completion of PRRT is associated with a worse outcome in terms of OS. Patients with greater liver involvement and highest CgA levels are more likely to progress within 12 months of treatment completion. Earlier treatment with PRRT in patients with radiological progression not meeting RECIST criteria may need to be conisdered. There may be a greater survival benefit if PRRT is given prior to the development of large volume disease.

Abstract
8528 Background: Bronchial Neuroendocrine tumours (NETs) are rare with an incidence of between 0.2 – 2 per 100,000 population. There has been an increase in prevalence due to increased awareness, enhanced immunohistochemistry and greater use of Computed tomography (CT). Bronchial NETs are classified according to the WHO guidelines developed in 2004 where they are graded by histological classification into ‘typical’, ‘atypical’ NETs or small and large neuroendocrine carcinoma’s (NECs). Typical NETs are regarded as being low-grade malignant however metastatic disease can still develop. Aims: We sought to determine the incidence of metastatic typical bronchial NETs, their survival and investigate the imaging and treatment used in their management. Methods: We performed a retrospective analysis of all bronchial NETs managed at our centre from 2001 to 2016. From those identified as typical NETs, we analysed clinical records in those with advanced disease (Stage IV). Results: From a total of 251 bronchial NETs, there were 147 ‘Typical’ NETs, 30(20%) of whom had advanced disease compared to 82 'Atypical' bronchial NETs of whom 55 had advanced disease (67%). The median age at diagnosis was 58 (range 24-77). In the 'Typical' NETs, 24/30 had liver metastases, 19/30 skeletal metastases, and 16 had carcinoid syndrome (CS). Functional imaging with FDG PET scan was positive in 7/10 patients and somatostatin receptor scintigraphy (SRS) positive in 16/20 and in 4/11 there was avidity with both. 20 patients were treated with somatostatin analogues predominantly for CS symptoms. 11 patients treated with peptide radiolabelled receptor targeted therapy (PRRT) with a median Time-To-Progression (TTP) of 27 months. 11 patients received chemotherapy with median TTP of 16 months with 4 patients demonstrating partial response. Conclusions: Typical bronchial NETs can lead to advanced disease in up to 20% of patients. Their behavior can be aggressive and is not predictable by histology alone. Functional imaging with both FDG and SRS may help determine the most appropriate treatment. Both PRRT and chemotherapy can be considered in progressive disease.

Abstract
PURPOSE Small intestinal neuroendocrine tumors (SINET) are the commonest malignancy of the small intestine; however, underlying pathogenic mechanisms remain poorly characterized. Whole-genome and -exome sequencing has demonstrated that SINETs are mutationally quiet, with the most frequent known mutation in the cyclin-dependent kinase inhibitor 1B gene (CDKN1B) occurring in only ∼8% of tumors, suggesting that alternative mechanisms may drive tumorigenesis. The aim of this study is to perform genome-wide molecular profiling of SINETs in order to identify pathogenic drivers based on molecular profiling. This study represents the largest unbiased integrated genomic, epigenomic, and transcriptomic analysis undertaken in this tumor type. EXPERIMENTAL DESIGN Here, we present data from integrated molecular analysis of SINETs (n = 97), including whole-exome or targeted CDKN1B sequencing (n = 29), HumanMethylation450 BeadChip (Illumina) array profiling (n = 69), methylated DNA immunoprecipitation sequencing (n = 16), copy-number variance analysis (n = 47), and Whole-Genome DASL (Illumina) expression array profiling (n = 43). RESULTS Based on molecular profiling, SINETs can be classified into three groups, which demonstrate significantly different progression-free survival after resection of primary tumor (not reached at 10 years vs. 56 months vs. 21 months, P = 0.04). Epimutations were found at a recurrence rate of up to 85%, and 21 epigenetically dysregulated genes were identified, including CDX1 (86%), CELSR3 (84%), FBP1 (84%), and GIPR (74%). CONCLUSIONS This is the first comprehensive integrated molecular analysis of SINETs. We have demonstrated that these tumors are highly epigenetically dysregulated. Furthermore, we have identified novel molecular subtypes with significant impact on progression-free survival.

Abstract
OBJECTIVE To describe the use of combined ursodeoxycholic acid (UDCA) and rifampicin treatment in intrahepatic cholestasis of pregnancy (ICP). STUDY DESIGN A questionnaire survey of 27 women with 28 affected pregnancies identified via the UK and International Obstetric Medicine forum. The clinical case notes of women with ICP treated with combined UDCA and rifampicin therapy were reviewed, and data regarding maternal and perinatal outcomes extracted. RESULTS Serum bile acids remained high whilst taking UDCA as monotherapy. In 14 pregnancies (54%) serum bile acids decreased following the introduction of rifampicin. In 10 pregnancies (38%), there was a 50% reduction in serum bile acids. There were no adverse effects reported with either drug. CONCLUSIONS This is the first report of the use of rifampicin in ICP. The data suggest that combined treatment with UDCA and rifampicin is an effective way of treating women with severe ICP who do not respond to treatment with UDCA alone.

Abstract
BACKGROUND/AIM Breast cancer (BC) is the leading global cause of cancer-related death in women. There is growing evidence for a role for dietary factors in BC pathophysiology. The aim of the present review was to evaluate the impact of dietary factors in BC risk. MATERIALS AND METHODS Bibliographical searches were performed in PubMed, using the following terms: "nutrition and breast cancer", "nutrition and breast carcinoma", "dietary factors and breast cancer", "risk factors and breast cancer", "diet and breast cancer, "breast cancer epidemiology", "breast cancer and prevention". RESULTS Consumption of well-done red meat appears to be associated with increased risk of BC, whereas fish may be protective. Total cholesterol, triglyceride levels and glycaemic load should be monitored and controlled in at risk populations because they may be associated with increased risk of BC, although the exact mechanisms involved are not clear. Alcohol intake should be minimized since it is a risk factor for BC. High intake of polyphenol/phyto-oestrogen -rich food (i.e. flavonoids, soya products), as well as fibres, fruits and vegetables, may have potential protective effects against BC occurrence but the results might vary according to hormonal status. Vitamin D supplements appear protective against BC development and similarly other vitamins and oligo-elements might decrease BC risk, although further large prospective studies are required. CONCLUSION There exist increasing evidence that dietary factors can play an important role in both the development and prevention of BC. Large randomized clinical and epidemiological studies are required but are difficult to design due to the number of variable factors.

Abstract
BACKGROUND/AIM Interferon alpha (IFNα) is used sparingly in the management of neuroendocrine tumors (NETs) due to toxicity and perceived limited efficacy. Other medical therapeutic options include somatostatin analogues and molecular-targeted agents, as well as chemotherapy and radionuclide targeted-therapy. The aim of the present study was to perform a retrospective analysis of patients treated with IFNα. PATIENTS AND METHODS Patients were identified from the NET database. Radiological, biochemical and symptomatic response were assessed. Progression-free survival (PFS), adverse events and toxicities were recorded. RESULTS Thirty-five patients were treated with IFNα, with a mean age of 60.1 (range=38-85) years; eight patients (23%) withdrew before 3 months, one (3%) had complete response; there was one partial response; 25 patients (71%) had at least three months of stable disease. The median PFS was 25 months. CONCLUSION IFNα demonstrated efficacy and was reasonably tolerated. IFNα may still have a role in small-volume diffuse disease, in syndromic patients where there is resistance to somatostatin analogue, or as a bridge to other therapies.

Abstract
Background Prostate cancer is the second most common cause of cancer worldwide after lung cancer. There is increasing evidence that diet and lifestyle plays a crucial role in prostate cancer biology and tumourigenesis. Prostate cancer itself represents a good model of cancer in which to look for chemopreventive agents due to the high disease prevalence, slowly progressive nature, and long latency period. Dietary agents have gained considerable attention, often receiving much publicity in the media. Aim To review the key evidence available for potential chemopreventive nutrients. Methods The methodology for this review involved a PubMed search from 1990 to 2013 using the key-words “diet and prostate cancer”, “nutrition and prostate cancer”, “dietary factors and prostate cancer”, “prostate cancer epidemiology”, “prostate cancer prevention”, “prostate cancer progression”. Results Red meat, dietary fat and milk intake should be minimised as they appear to increase the risk of prostate cancer. Fruit and vegetables and polyphenols may be preventive in prostate cancer, but further studies are needed to draw more solid conclusions and to clarify their role in patients with an established diagnosis of prostate cancer. Selenium and vitamin supplements cannot be advocated for the prevention of prostate cancer and indeed higher doses may be associated with a worse prognosis. There is no specific evidence regarding benefits of probiotics or prebiotics in prostate cancer. Conclusions From the wealth of evidence available, many recommendations can be made although more randomised control trials are required. These need to be carefully designed due to the many confounding factors and heterogeneity of the population.

Abstract
212 Background: Aberrant DNA methylation is known to play an important role in the pathogenesis of many human cancers, however little is known about its role in gastrointestinal neuroendocrine tumours (GI NET) development. We report the first unbiased genome-wide DNA methylation analysis of a large cohort of GI NETs, aiming to identify key methylation variable positions (MVPs) specific to GI NETs which may contribute to tumorigenesis and metastatic progression. Methods: Illumina Infinium Human Methylation 450 Array analysis was performed on 56 cases of GI NET DNA extracted from macrodissected tumour (n=67) and normal (n=29) specimens. Tumours were gastrointestinal primaries (n=39) or metastases (liver, mesenteric, omental or lymph node, n=28) of low (n=35), intermediate (n=17) or high grade (n=3)(unknown grade n=12). Data analysis was performed using the "ChAMP" custom pipeline and pathway analyses were performed using "GREAT," "WebGestalt," and "GSEA" web tools. A Bonferroni adjusted significance threshold value of p<0.05 was used throughout. Results: In order to identify and validate a GI NET specific methylation signature our cohort was divided into a discovery set (31 cases) and validation set (25 cases). Comparison of primary GI NET tumours with normal small bowel identified a total of 77,916 MVPs, including 1,666 sites hypermethylated by over 30% in tumour compared to normal tissue. Application of the profile to the validation set correctly identified 85% of samples. Tumours demonstrated global hypomethylation relative to normal tissue. Gene ontology analysis identified methylation of multiple cancer related pathways (including the Wnt, mTOR and Notch pathways) as a feature of hepatic metastases of GI NET primaries. Increasing RASSF1 promoter hypermethylation was associated with higher tumour grade. Conclusions: This study is the first comprehensive analysis of the epigenetic profile of GI NETs and identifies potential novel biomarkers and therapeutic targets. We are currently performing integrated analysis of epigenomic, genomic and transcriptomic data to further define the pathways involved in GI NET pathogenesis.

Abstract
BACKGROUND Pancreatic cancer is the fourth leading cause of cancer death in men and women. Prognosis is poor with a 5-year survival rate of less than 5%. As there is no effective screening modality, the best way to reduce morbidity and mortality due to pancreatic cancer is by effective primary prevention. AIM To evaluate the role of dietary components in pancreatic cancer. MATERIALS AND METHODS Bibliographical searches were performed in PubMed using the terms "pancreatic cancer", together with "nutrition", "diet", "dietary factors", "lifestyle", "smoking", "alcohol" and "epidemiology". RESULTS Fruits (particularly citrus) and vegetable consumption may be beneficial. The consumption of whole grains has been shown to reduce pancreatic cancer risk and fortification of whole grains with folate may confer further protection. Red meat, cooked at high temperatures, should be avoided, and replaced with poultry or fish. Total fat should be reduced. The use of curcumin and other flavonoids should be encouraged in the diet. There is no evidence for benefit from vitamin D supplementation. There may be benefit for dietary folate. Smoking and high Body Mass Index have both been inversely associated with pancreatic cancer risk. CONCLUSION The lack of randomized trials and the presence of confounding factors including smoking status, physical activity, distance of habitat from the equator, obesity, and diabetes may often result in inconclusive results. There is evidence to encourage the use of whole grain in the staple diet and supplementation within the diet of folate, curcumin and other flavanoids. Carefully designed randomized trials are required to further elucidate these important matters.

Abstract
BACKGROUND Colorectal cancer is the third commonest cancer and the third leading cause of cancer death among men and women. It has been proposed that dietary factors are responsible for 70-90% of colorectal cancer and diet optimization may prevent most cases. AIM To evaluate the role of dietary components and supplements in colorectal cancer. METHODS Bibliographical searches were performed in Pubmed for the terms "diet and colorectal cancer", "diet and colon cancer", "diet and rectal cancer", "nutrition and colorectal cancer", "probiotics and colorectal cancer", "prebiotics and colorectal cancer", "alcohol and cancer" and "colorectal cancer epidemiology". RESULTS Consumption of processed or red meat, especially when cooked at high temperatures may be associated with increased risk of colorectal cancer. The evidence for dietary fibre is unclear but foods that contain high amounts of fibre are usually rich in polyphenols which have been shown to alter molecular processes that can encourage colorectal carcinogenesis. Meta-analyses provide evidence on the benefits of circulating, diet-derived and supplemented, vitamin D and Calcium. We also found that diets rich in Folate may prevent colorectal carcinoma. The evidence on dietary micronutrients such as Zinc and Selenium in association with colorectal cancer is not conclusive. It has been suggested that there may be a direct association between alcohol intake and colorectal cancer. In vitro and in vivo studies have highlighted a possible protective role of prebiotics and probiotics. CONCLUSIONS The lack of randomized trials and the presence of confounding factors including smoking, physical activity, obesity and diabetes may often yield inconclusive results. Carefully designed randomized trials are recommended.

Abstract
UNLABELLED Budd-Chiari syndrome (BCS) is a rare, life-threatening disease caused by obstruction of hepatic venous outflow. The aim of the study was to assess long-term outcome and identify prognostic factors in BCS patients managed by a step-wise approach using anticoagulation, angioplasty/thrombolysis, transjugular intrahepatic portosystemic shunting (TIPS), and orthotopic liver transplantation (OLT). We reviewed long-term data on 157 patients previously included by the European Network for Vascular Disorders of the Liver, a multicenter prospective study of newly diagnosed BCS patients in nine European countries. Patients were followed for a median of 50 months (range, 0.1-74.0). During the study, 88 patients (56%) received at least one invasive intervention (22 patients angioplasty/thrombolysis, 62 TIPS, and 20 OLT) and 36 (22.9%) died. Most interventions and/or deaths occurred in the first 2 years after diagnosis. The Rotterdam score was excellent in predicting intervention-free survival, and no other variable could significantly improve its prognostic ability. Moreover, BCS-TIPS prognostic index (PI) score (based on international normalized ratio, bilirubin, and age) was strongly associated with survival and had a discriminative capacity, which was superior to the Rotterdam score. CONCLUSIONS The current study confirms, in a large cohort of patients with BCS recruited over a short period, that a step-wise treatment approach provides good long-term survival. In addition, the study validates the Rotterdam score for predicting intervention-free survival and the BCS-TIPS PI score for predicting survival.

Abstract
Neuroendocrine tumours of the Colon and Rectum are rare but are increasing in incidence as a result of greater investigation with endoscopy and improved histological reporting. Classification with the 2010 WHO TNM staging system as well as grading based on the Ki-67 index has led to improved prognostic assessment. The use of Endoanal Ultrasound has increased the sensitivity of detection of depth of invasion and lymphovascular involvement, which is associated with a poor prognosis. Standard polypectomy has largely been replaced by endoscopic mucosal resection of smaller polyps, although newer techniques such as band ligation or endoscopic submucosal dissection are likely to be associated with less residual disease. The management of advanced disease remains a challenge but new treatments such as Peptide Receptor Targeted therapy and molecular targeted treatments offer hope of improved progression free survival in non-resectable disease.
