Abstract
PURPOSE Peritoneal metastases (PM) of neuroendocrine neoplasm (NEN) origin are identified with increasing frequency and exert a significant effect on quality of life and clinical status of the patients. The aim of this study was to identify the characteristics and the prognostic significance of PM in patients with NENs. METHODS A retrospective analysis of the data of patients from two tertiary referral centers was performed. We defined a control group of age- and gender-matched NEN patients with comparable stage IV disease but no PM. RESULTS We analysed 70 patients (41 females) with PM. Small intestine was the most common primary NEN site (87.1%). PM prevalence was 10.3%. Forty-four patients presented with synchronous PM, whereas 26 developed metachronous PM. The majority of patients had other concomitant metastases (50 hepatic, 6 lung and 12 bone metastases). Twelve patients developed intestinal obstruction. After PM diagnosis, 76% of patients received treatment with somatostatin analogues while six patients (8.6%) were treated with peptide receptor radionuclide therapy (PRRT). The median progression-free survival (PFS) in the PRRT-treated group was 15 months (95% CI 2-28). Median overall survival (OS) in the PM group was 142 months [95% CI 71-213] while it was not reached in the control group. CONCLUSION Peritoneal metastases show low prevalence among NEN patients and are most likely to develop in patients with small intestinal NENs and advanced metastatic disease. The presence of PM does seem to be associated with a negative prognostic impact on OS of NEN patients and their identification and prompt treatment is of major importance.

Abstract
Bone metastases from gastroenteropancreatic neuroendocrine neoplasms (GEPNENs) have been associated with poor prognosis, but it is unclear whether patients with concurrent bone metastases who receive liver-directed therapy (LDT) would derive survival benefit. The California Cancer Registry dataset, merged with data from the California Office of Statewide Health Planning and Development, was used to perform a retrospective study of GEPNENs metastatic to both liver and bone between 2000 and 2012. A total of 203 patients were identified. Of these, 14.8% underwent LDT after bone metastasis diagnosis, 22.1% received LDT prior to that diagnosis, and 63.1% never received LDT. The median overall survival from the time of bone metastasis diagnosis was significantly longer in those that received LDT after diagnosis when compared with those that never received LDT (p = 0.005) and was not significantly different from the median overall survival of those that had received LDT prior to diagnosis (p = 0.256). LDT may still be associated with improved survival even after a diagnosis of bone metastasis.

Abstract
BACKGROUND Incorporation of patient-reported outcomes such as health-related quality of life has become increasingly important in the management of chronic diseases such as cancer. In this prospective study, we examined the effect of surgical resection on quality of life in patients with intestinal and pancreatic neuroendocrine tumors (NETs). METHODS Thirty-two patients underwent NET resection at our institution from January 2020 to January 2022. All patients completed the 12-item short-form quality-of-life survey prior to surgery, as well as at the 3-, 6-, and 12-month postoperative time points. The presence and severity of specific carcinoid syndrome symptoms (diarrhea, flushing, and abdominal pain) were also recorded during pre- and postoperative appointments. RESULTS Patients experienced significant increases in both mental and physical health after surgery. Mental health scores significantly increased at all three time points (baseline: 51.33; 3-month: 53.17, p = 0.02; 6-month: 57.20, p < 0.001; 12-month: 57.34, p = 0.002), and physical health scores increased at 6 and 12 months (baseline: 50.39; 6-month: 53.16, p = 0.04; 12-month: 55.02, p = 0.003). Younger patients benefited more in terms of physical health, while older patients had more significant increases in mental health. Patients with metastatic disease, larger primary tumors, and those receiving medical therapy had lower baseline quality-of-life scores and greater improvements after surgery. The vast majority of patients in this study also experienced alleviation of carcinoid syndrome symptoms. CONCLUSIONS In addition to prolonging survival, resection of intestinal and pancreatic NETs leads to significantly improved patient-reported quality of life.

Abstract
Peritoneal metastasis (PM) in gastroenteropancreatic neuroendocrine tumors (GEP-NET) and hepato-pancreato-biliary (HPB) tumors has a low incidence and has rarely been studied as a stand-alone condition. The clinical relevance of PM in HPB tumors and GEP-NET arises from the fact that PM significantly worsens the prognosis of the underlying tumors. In GEP-NET, the particular situation is that PM has a negative prognostic impact compared to patients without metastases, which is not evident compared to patients with metastases in other locations. Complete surgical cytoreduction (CRS) is a curative treatment option for patients with PM in GEP-NET. Complete surgical resection should always be strived for, although patients may benefit from incomplete resection (70-90%) or resection of the primary tumor alone. Additional hyperthermic chemoperfusion (HIPEC) is currently not recommended. For nonresectable GEP-NET, systemic treatment is available that is oriented to the studies for generally metastasized GEP-NET. For PM in carcinomas of the bile duct and pancreatic carcinomas, there are no valid data or indications for CRS and HIPEC. In contrast, case series for PM in hepatocellular carcinoma (HCC) after CRS or CRS/HIPEC show good survival outcomes that justify a surgical approach under the condition of a complete resection. Patients with PM in GEP-NET and HCC should therefore be referred to a center for peritoneal tumor surgery to evaluate the option of complete CRS and use it as a curative option.

Abstract
The chief causes of death of patients with GEPNETs are liver failure from hepatic replacement by tumor in the majority and bowel obstruction in the remainder. Many patients are with liver metastases are actually eligible for hepatic cytoreductive operations, even if they have numerous bilobar metastases and extra-hepatic disease, provided that greater than 70% of the liver tumor volume can be removed. This can often be done by combinations of parenchyma-sparing enucleations, wedge resections and radio frequency ablations. Patients with higher liver tumor burden can be treated with intra-arterial therapies, such as embolization and chemoembolization. Patients with peritoneal carcinomatosis are recommended to undergo cytoreductive operations including peritoneal stripping and bowel resections. Consensus guidelines by experts recommend bisphosphonate therapy for patients with bone metastases, reserving surgical treatment for patients with mechanical issues and/or potential spinal cord compression. Radiation can be employed for isolated painful metastases. PRRT may be an emerging therapy for treatment of bone metastases.

Abstract
INTRODUCTION Peritoneal metastases from neuroendocrine tumors are associated with a bad prognosis. The objective of our study was to evaluate whether surgical resection could lead to prolonged survival in selected patients. This survival was compared to that of patients operated for liver metastasis. METHODS From our prospectively maintained database we included 88 patients who underwent the complete resection of peritoneal and/or liver metastasis between January 1995 and December 2016 in Gustave-Roussy. Three resection groups were compared: peritoneal metastasis alone, liver metastasis alone, and the combined resection of liver and peritoneal metastases. RESULTS The median peritoneal cancer index was 10 in the peritoneal group and 11 in the peritoneal + liver group. The 5-year overall survival was 81% (60-100) in the peritoneal group compared to 78% (65.2-92.8) in the liver group, and 72% (58.7-89.7) in the peritoneal + liver group (p = 0.71). The 3-year disease-free survival reached 26.9% (16.1-45.1) in the liver group, 12.5% (2.3-68.2) in the peritoneal group, and 32.4% (19.9-52.6) in the combined liver + peritoneal group (p = 0.45). In the univariate analysis, the prognosis factors for a longer survival were: small bowel primary tumor origin, low preoperative chromogranin A level, and tumor grade ≤1. CONCLUSION Despite a high recurrence rate, long-term overall survival can be achieved after the resection of peritoneal metastasis in selected patients. This survival is comparable to that of patients operated for liver metastasis only. Surgery should stand as a standard treatment for peritoneal metastases in patients with resectable disease.

Abstract
Neuroendocrine tumors (NETs) are rare neoplasms, with an estimated annual incidence of 6.9/100 000. They arise from cells of the diffuse endocrine system, which are mainly dispersed throughout the gastrointestinal (GI), pancreatic, and respiratory tracts. The incidence of GI-NETs has recently begun to show a steady increase. According to the Surveillance, Epidemiology, and End Results database, 53% of patients with NETs present with localized disease, 20% with locoregional disease, and 27% with distant metastases at the time of diagnosis. Surgery is the mainstay for the treatment of locoregional GI-NETs. Endoscopic resection is an option for well-differentiated early GI-NETs, which are thought to very rarely metastasize to lymph nodes. A lesion that is technically difficult to resect via endoscopy is an indication for local resection (partial resection without lymph node dissection). GI-NETs with possible lymph node metastasis is an indication for enterectomy with lymph node dissection. For NETs with metastatic lesions, cytoreduction surgery can control hormonal hypersecretion and alleviate symptoms; therefore, cytoreduction surgery is recommended. The indications for surgery vary and are based on the organ where the NET arose; therefore, an understanding of the patient's clinical state and individualized treatment that is based on the characteristics of the patient's GI-NET is needed. This review summarizes surgical treatments of GI-NETs in each organ.

Abstract
BACKGROUND The value of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for patients with peritoneally metastasized goblet-cell carcinoids (GCCs) and mixed adenoneuroendocrine carcinomas (MANECs) is currently unclear. We compared outcomes of CRS-HIPEC to surgery alone for peritoneally metastasized GCCs and MANECs. PATIENTS AND METHODS Two cohorts were obtained from the Netherlands Cancer Registry (n = 569): patients with peritoneally metastasized GCCs and MANECs treated with CRS-HIPEC in Dutch and Belgian centers (n = 45), and patients treated with surgery alone. Primary outcome was overall survival (OS). Secondary outcomes were morbidity and hospital mortality. After propensity score matching, OS was compared in univariate and multivariate analyses. A systematic literature review was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines from database inception to June 25, 2018. RESULTS After matching for sex, tumor stage, lymph node stage, and liver metastases, CRS-HIPEC was associated with improved median OS in the combined GCC and MANEC group and the separate GCC subgroup in univariate (GCC + MANEC: 39 vs. 12 months, P < .001; GCC: 39 vs. 12 months, P = .017) and multivariate analysis (GCC + MANEC: hazard ratio 4.27, 95% confidence interval 1.88-9.66, P = .001; GCC: hazard ratio 2.77, 95% confidence interval 1.06-7.26, P = .038). Acceptable grade III-IV morbidity (17.5%) and mortality (0) were seen after CRS-HIPEC. The literature review supported these findings. CONCLUSION CRS-HIPEC is associated with substantial survival benefit in patients with peritoneally metastasized GCCs and MANECs compared to surgery alone and is a safe treatment option. These data support centralized care of GCC and MANEC patients with peritoneal spread in expert centers offering CRS-HIPEC.

[PMID: 32473829 DOI: 10.1016/j.surg.2020.03.030] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Revised: 03/05/2020] [Accepted: 03/31/2020] [Indexed: 01/08/2023]
Abstract
BACKGROUND This study determines how much cytoreduction for small bowel neuroendocrine tumors with peritoneal carcinomatosis and liver metastases can be achieved and the corresponding survival benefits of different levels of clearance. METHODS Records of patients with small bowel neuroendocrine tumors with peritoneal carcinomatosis were reviewed and scored using the Lyon Stage system. Kaplan-Meier survival was calculated and compared by log-rank analysis. RESULTS Among 323 patients with small bowel neuroendocrine tumors identified, 98 (30%) had peritoneal carcinomatosis. At laparotomy, 82% had Lyon Stage ≥3 compared with 78% who had Lyon Stage ≤2 after debulking (P < .00001). Median overall survival for Lyon Stage = 0 was 132 months and 51 months for Lyon Stage ≥1 (P = .026). For incomplete clearance, overall survival was 76 months for Lyon Stage ≤1 compared with 32 months for Lyon Stage ≥3 (P = .037). Seventy-nine (81%) patients had liver metastases, and 57 underwent >70% liver metastases cytoreduction. Overall survival was 76 months for Lyon Stage ≤1 and >70% liver metastases cytoreduction, 38.5 months for Lyon Stage ≥3 and >70% liver metastases cytoreduction, 22 months for Lyon Stage ≤1 and liver metastases not cytoreduced, and 20 months for Lyon Stage ≥3 and liver metastases not cytoreduced (P = .018). CONCLUSION A majority of patients with peritoneal carcinomatosis from small bowel neuroendocrine tumors can be cytoreduced. Best survival times are seen with complete clearance; however, there are improved survival times for Lyon Stage ≤1. In patients with liver metastases, best survival after cytoreduction is seen when both Lyon Stage ≤1 and liver metastases >70% are achieved.

Abstract
BACKGROUND Peritoneal carcinomatosis (PC) can affect the quality of life of patients with gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NENs). Peritoneal disease control by medical therapies in these patients has been poorly investigated Objectives: To describe, in a consecutive series of GEP-NENs, the clinical impact of PC and to report the effectiveness of available treatments in PC control. METHODS A retrospective, monocenter analysis was performed of 135 GEP-NENs (1993-2016) with at least a 12-month follow-up. Peritoneal disease progression was defined as detection of a significant increase in size or appearance of new implants by imaging. RESULTS A total of 62.9% of cases had diffuse PC (involving at least 2 abdominal quadrants). According to WHO 2017 classification, cases were 42.3% neuroendocrine tumors NET-G1, 45.5% NET-G2, 6.5% NET-G3, 4.9% neuroendocrine carcinomas NEC-G3, and 0.8% mixed neuroendocrine-nonneuroendocrine neoplasms. Bowel obstruction occurred in 30 (22.2%) patients mainly depending on size of peritoneal implants (HR: 1.10; 95% CI: 1.02-1.20; p = 0.01). Patients with diffuse PC treated with peptide receptor radionuclide therapy (PRRT) showed peritoneal progression in 37.5% of cases, and bowel obstruction or ascites in 28.1%. Better peritoneal disease control was observed in cases receiving somatostatin analogs at first-line therapy, probably due to a less aggressive disease behavior for these patients. CONCLUSIONS Bowel obstruction is not uncommon in GEP-NENs with PC. PRRT should be adopted with caution in GEP-NENs with diffuse PC, but larger series are needed to confirm these data.

Abstract
PURPOSE Somatostatin analogs (SSAs) are recommended for the first-line treatment of most patients with well-differentiated, gastroenteropancreatic (GEP) neuroendocrine tumors; however, benefit from treatment is heterogeneous. The aim of the current study was to develop and validate a progression-free survival (PFS) prediction model in SSA-treated patients. PATIENTS AND METHODS We extracted data from the Spanish Group of Neuroendocrine and Endocrine Tumors Registry (R-GETNE). Patient eligibility criteria included GEP primary, Ki-67 of 20% or less, and first-line SSA monotherapy for advanced disease. An accelerated failure time model was developed to predict PFS, which was represented as a nomogram and an online calculator. The nomogram was externally validated in an independent series of consecutive eligible patients (The Christie NHS Foundation Trust, Manchester, United Kingdom). RESULTS We recruited 535 patients (R-GETNE, n = 438; Manchester, n = 97). Median PFS and overall survival in the derivation cohort were 28.7 (95% CI, 23.8 to 31.1) and 85.9 months (95% CI, 71.5 to 96.7 months), respectively. Nine covariates significantly associated with PFS were primary tumor location, Ki-67 percentage, neutrophil-to-lymphocyte ratio, alkaline phosphatase, extent of liver involvement, presence of bone and peritoneal metastases, documented progression status, and the presence of symptoms when initiating SSA. The GETNE-TRASGU (Treated With Analog of Somatostatin in Gastroenteropancreatic and Unknown Primary NETs) model demonstrated suitable calibration, as well as fair discrimination ability with a C-index value of 0.714 (95% CI, 0.680 to 0.747) and 0.732 (95% CI, 0.658 to 0.806) in the derivation and validation series, respectively. CONCLUSION The GETNE-TRASGU evidence-based prognostic tool stratifies patients with GEP neuroendocrine tumors receiving SSA treatment according to their estimated PFS. This nomogram may be useful when stratifying patients with neuroendocrine tumors in future trials. Furthermore, it could be a valuable tool for making treatment decisions in daily clinical practice.

Abstract
BACKGROUND Neuroendocrine tumors (NETs) have a uniquely indolent biology. Management focuses on tumor and hormonal burden reduction. Data on cytoreduction with extrahepatic disease remain limited. OBJECTIVE We sought to define the outcomes of cytoreduction for metastatic NETs with extrahepatic metastases. METHODS Patients undergoing cytoreductive surgery for grade 1 or 2 NETs with extrahepatic metastases (with or without intrahepatic disease) were identified from an institutional database (2003-2014). Primary outcomes included postoperative hormonal response (> 50% urinary 5HIAA decrease), progression-free survival (PFS) and overall survival (OS), while secondary outcomes were 30-day postoperative major morbidity (Clavien grade III-V), mortality, and length of stay. RESULTS Fifty-five patients were identified (median age 59.3 years, 80% small bowel primaries, 56.4% grade 1); 87% of patients presented with combined intra- and extrahepatic metastases. Resection most commonly included the liver (87%), small bowel (22%), mesenteric (25%) and retroperitoneal (11%) lymph nodes, and peritoneum (7%). Thirty-day major morbidity (Clavien III-V) was 18%, with 3.6% mortality, and median length of stay was 7 days [interquartile range (IQR) 5-9]. Liver embolization was performed in 31% of patients after surgery, at a median of 23 months following surgery. Overall, postoperative hormonal response occurred in 70% of patients. At median follow-up of 37 months (IQR range 22-93), 42 (76%) patients were alive and 23 (41.8%) had progressed. Five-year OS was 77% and 5-year PFS was 51%. CONCLUSION Patients undergoing cytoreduction of metastatic well-differentiated NET in the setting of extrahepatic metastatic disease experience good tumoral control with favorable PFS and OS. Cytoreductive surgery can be safely included in the therapeutic armamentarium for NET with extrahepatic metastases.

Abstract
AIM The aim of this study was to assess the outcomes of patients operated on for peritoneal metastases from unusual cancer sites of origin, meaning apart from peritoneal metastases (PM) from colorectal, gastric and epithelial ovarian carcinomas, pseudomyxoma peritonei and mesothelioma. PATIENTS AND METHODS A questionnaire concerning patients treated with cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) for PM arising from unusual cancer sites of origin was sent to all centres, which routinely performed HIPEC, through the Peritoneal Surface Oncology Group International and the RENAPE network. RESULTS Between September 1990 and June 2016, 850 procedures for unusual cases were performed in 781 patients, in 53 centres worldwide. Nearly two-thirds of the procedures were performed for three indications: rare ovarian carcinoma (n = 224), sarcoma (n = 189) and neuroendocrine tumours (n = 127). The median PCI was 12 [0-39]. Grade III-IV postoperative complications occurred in 272 patients (41%). Nineteen patients (2.9%) died postoperatively. After a median follow-up of 46 months, median overall survival (OS) was 39 months [33.18-44.05]. Five-year OS rate was 38.7%. For the three main indications, 5-year OS was significantly greater in patients with PM from rare ovarian carcinoma (57.7%), than that of patients with PM from neuroendocrine tumours (39.9%), and from sarcoma (29.3%) (p < 0.0001). CONCLUSIONS CRS and HIPEC appear to be safe and effective in patients with peritoneal metastases from unusual cancer sites of origin, especially from rare ovarian carcinomas, PM from neuroendocrine tumours. The respective roles of CRS and HIPEC remain unclear and should be evaluated.

Abstract
Background Pancreatic neuroendocrine neoplasias (pNENs) are uncommon but fascinating tumors with an annual incidence of 1 per 100,000 people. pNENs present either as functional tumors, causing specific hormonal syndromes like Zollinger-Ellison syndrome (ZES) or organic hyperinsulinism, or as non-functional pancreatic tumors (NF-pNENs). The natural history of pNENs is highly variable. 90% of all insulinomas or small NF- pNENs are readily curable by surgical resection. Most other functional and late detected NF-pNENs have a less favorable chance for cure. Methods A systematic review of the literature was performed to identify the current state of the art with regard to the key issues of surgery in pNEN G1/G2. Results This article provides a comprehensive review of the current literature addressing the current challenges in pNEN surgery. Conclusion Patients with completely resected tumors generally have a good prognosis, and an aggressive surgical approach combined with conservative treatment options in patients with advanced disease rarely provides cure but often results in long-term survival.

Abstract
BACKGROUND Focal adhesion kinase (FAK) mediates survival of normal pancreatic islets through activation of AKT. Upon malignant transformation of islet cells into pancreatic neuroendocrine tumors (PanNETs), AKT is frequently overexpressed and mutations in the AKT/mTOR pathway are detected. Because mTOR inhibitors rarely induce PanNET tumor regression, partly because of feedback activation of AKT, novel combination strategies are needed to target FAK/AKT/mTOR signaling. METHODS We characterized the activation of FAK in PanNETs using immunohistochemistry and Western blot analysis and tested the FAK inhibitor PF-04554878 in human PanNET cells in vitro and in vivo (at least three mice per group). In addition, we evaluated the effect of combined FAK and mTOR inhibition on PanNET viability and apoptosis. All statistical tests were two-sided. RESULTS We found that FAK is overexpressed and hyperphosphorylated in human PanNETs and that PF-04554878 strongly inhibited FAK (Tyr397) autophosphorylation in a dose-dependent manner. We found that PF-04554878 inhibited cell proliferation and clonogenicity and induced apoptosis in PanNET cells. Moreover, oral administration of PF-04554878 statistically significantly reduced tumor growth in a patient-derived xenograft model of PanNET (P = .02) and in a human PanNET xenograft model of peritoneal carcinomatosis (P = .03). Importantly, PF-04554878 synergized with the mTOR inhibitor everolimus by preventing feedback AKT activation. CONCLUSIONS We demonstrate for the first time that FAK is overexpressed in PanNETs and that inhibition of FAK activity induces apoptosis and inhibits PanNET proliferation. We found that the novel FAK inhibitor PF-04554878 synergizes with everolimus, a US Food and Drug Administration-approved agent for PanNETs. Our findings warrant the clinical investigation of combined FAK and mTOR inhibition in PanNETs.

Abstract
Neuroendocrine tumours (NETs) are a family of neoplasms that come from neuroendocrine cells and express neural markers, such as synaptophysin or chromogranin A. The current classifications of these tumours are presented by the WHO 2000 classification, based on histological parameters, and the WHO 2010 classification, based on the proliferative index, that divides the NETs into a neuroendocrine tumour of a low grade, neuroendocrine tumour of a intermediate grade and neuroendocrine carcinoma (NEC) of a high grade. We are reporting a very rare case of a G1 low-grade neuroendocrine tumour (NET) of the ileum with a peritoneal carcinomatosis. This case is challenging because the tumour expresses low proliferative index as G1 tumours, but it has an aggressive clinical behaviour such as node metastasis and peritoneal carcinomatosis. The peritoneal carcinomatosis is not actually considered by the current classifications of NETs, so it is difficult to predict the prognosis of this patient.

Abstract
European Neuroendocrine Tumor Society staging, together with the Ki67 grading system, has appeared as superior for classification of neuroendocrine tumors (NET). The management of small intestinal NET (SI-NET) has been overall controversial. Mesenteric metastases occur also with the smallest SI-NET, and the majority of patients risk to ultimately progress with liver metastases. 68Gallium (somatostatin receptor)/PET/CT has appeared as most sensitive for imaging, and fluorodeoxyglucose-PET is recommended to identify lesions with high proliferation. Our treatment policy for SI-NET is to initiate somatostatin analog treatment, and in order to prevent abdominal complications we recommend early intestinal resection for removal of primary tumors and clearance of lymph node metastases. Liver metastases are liberally treated by resection (or ablation), as this can efficiently palliate carcinoid syndrome-associated symptoms.

Abstract
Well-differentiated digestive neuroendocrine tumors (NET) are a heterogeneous group of neoplasms usually associated with slow growth but a high rate of metastases, including peritoneal carcinomatosis (PC). Herein, we aimed to comprehensively review the current knowledge of PC in terms of implications for the management and prognosis of patients with NET, including the latest studies and expert statements. NET-derived PC concerns about 17% of NET patients and up to 30% of those with small intestine primary NET. It has an independent pejorative prognostic impact. The extent of PC in NET patients and its severity can be expressed by analogy to other malignancies. However, it must be placed in the context of NET disorders, which usually vary from other PC-related malignancies. Recently, a gravity PC score was proposed by a consensus European Neuroendocrine Tumor Society (ENETS) expert group, but it requires validation. In addition, the form of peritoneal involvement (nodular or fusiform/infiltrative) might influence its prognosis and management. Aggressive surgical management seems justified for subsets of NET-related PC but requires careful selection of the candidates most likely to benefit. Cytoreductive surgery prolongs survival, especially when the peritoneal lesions are completely resected. Too little is known about the benefit of hyperthermic intraperitoneal chemotherapy for NET-derived PC, but if it confers an advantage, it would have to be counterbalanced by its high morbidity.

Abstract
BACKGROUND One-fifth of all patients with small-intestinal neuroendocrine tumors (SI-NETs) present with or develop peritoneal carcinomatosis (PC). Our aim was to determine the prognosis and genetic profiles of tumors in patients with PC compared with tumors in patients without PC. METHODS We included SI-NET patients (cases with PC, n = 73, and controls without PC, n = 468) who underwent operation between 1985 and 2012. The Lyon prognostic index was used to correlate the amount of PC to survival. DNA samples from patients with (n = 8) and without (n = 7) PC were analyzed with a single-nucleotide polymorphism array (HumanOmni2.5 BeadChip, Illumina) to investigate genetic disparities between groups. RESULTS Patients with PC had poorer survival (median 5.1 years) than controls (11.1 years). An advanced postoperative Lyon prognostic index was a negative prognostic marker for survival by multivariable analysis (P = .042). Patients with and without PC clustered differently based on loss of heterozygosity and copy number variation data from single-nucleotide polymorphism array of the primary tumors (P = .042). CONCLUSION SI-NET patients with PC have poor survival, which diminishes with increasing PC load after surgery. Clustering based on copy number variation and loss of heterozygosity data suggests different genotypes in primary tumors comparing patients with and without PC.

Abstract
Pancreatic neuroendocrine tumors (pNETs) are rare heterogeneous tumors that have been steadily increasing in both incidence and prevalence during the past few decades. Pancreatic NETs are categorized as functional (F) or nonfunctional (NF) based on their ability to secrete hormones that elicit clinically relevant symptoms. Specialized diagnostic tests are required for diagnosis. Treatment options are diverse and include surgical resection, intraarterial hepatic therapy, and peptide receptor radionuclide therapy (PRRT). Systemic therapy options include targeted agents as well as chemotherapy when indicated. Diagnosis and management should occur through a collaborative team of health care practitioners well-experienced in managing pNETs. Recent advances in pNET treatment options have led to the development of the Canadian consensus document described in this report. The discussion includes the epidemiology, classification, pathology, clinical presentation and prognosis, imaging and laboratory testing, medical and surgical management, and recommended treatment algorithms for pancreatic neuroendocrine cancers.

Abstract
Insulinoma are malignant in 4 to 14 % of cases. Their rarity and the sparse data available in the literature have limited publication of specific guidelines for their management. The following review aim to provide up-to-date recommendations on initial evaluation including pathologic grading, measures to control hypoglycemia, antitumor strategies and long term follow-up. Will be discussed in detail respective indications of surgery, diazoxide, somatostatin analogs, everolimus, sunitinib, liver directed treatments including arterial embolization, chemotherapy and radiometabolic therapy. A Medline search using terms "insulinoma", "neuroendocrine pancreatic tumors", "islet cell carcinoma", "malignant insulinoma" was performed limiting the selection to English language articles and adult age cases, along with cross referencing.

Abstract
The peritoneal cavity must be oncologically considered as an organ in its own right and peritoneal metastases (PM) must be treated with the same curative intent (and the same results) as liver metastases. The package combining complete cytoreductive surgery (CCRS) (treating the visible disease) plus hyperthermic intraoperative peritoneal chemotherapy (HIPEC) (treating the remaining non-visible disease) achieves cure in many patients. Twenty years of publication allow us to assemble sufficient background information and data to point out the good and poor indications for CCRS+HIPEC. HIPEC is the standard of care for the treatment of peritoneal pseudomyxomas and peritoneal mesotheliomas and also, recently for the treatment of colorectal PM with limited peritoneal extension. HIPEC is in the evaluation phase for gastric PM and ovarian PM after initially disappointing results, but it is highly probable that it will be useful in particular settings. PM from neuroendocrine tumours are in the same situation. HIPEC is not currently indicated for the treatment of PM from sarcomas, from GIST, and for small round-cell desmoplastic tumours, given the poor results obtained. HIPEC can be useful, on a case-by-case basis, to treat rare tumours complicated by isolated peritoneal diffusion (e.g. Frantz's tumours). HIPEC can be used in the prophylactic setting to prevent PM in patients with a high risk of developing PM, and the first results of the 'second-look' approach are promising. Finally, CCRS+HIPEC appear to be indispensable tools in the oncologist's armentarium.

Abstract
Little is known about patients with malignant digestive neuroendocrine tumours (MD-NETs). Although their incidence is increasing, MD-NETs remain a rare cancer, representing 1% of digestive cancers. Most MD-NETs are well-differentiated. MD-NET poorly differentiated carcinomas account for 20% of cases on average. Anatomical localisation of MD-NETs varied according to geographic region. Stage at diagnosis and prognosis for patients with MD-NETs in the general population are considerably worse than often reported from small hospital case series. Prognosis varies with tumour differentiation, anatomic site and histological subtype. There are significant differences in survival from MD-NETs among European countries, independent of other prognostic factors. Early diagnosis is difficult; new therapeutic options appear to represent the best approach to improving prognosis.

Abstract
Peritoneal carcinomatosis is a well-known factor of poor prognosis in patients with digestive adenocarcinomas. Peritoneal dissemination may also occur in midgut well-differentiated neuroendocrine tumors, but its influence on survival is ill-defined. We report here the history of a 64-year-old woman who had a neuroendocrine tumor of the cecum with multiple synchronous metastases in the liver and diffuse peritoneal carcinomatosis. She underwent surgical resection of the primary tumor and cytoreduction of liver metastases, and received subsequently chemotherapy and somatostatin analogs. In spite of the widespread extension of the disease, she survived for 13 years and died from a carcinoid heart disease. We discuss the natural history and prognostic factors in patients with midgut well-differentiated neuroendocrine tumors, with a focus on the impact of the peritoneal carcinomatosis.

Abstract
Carcinoid tumors are primary malignant neoplasms that arise from neuroendocrine cells. These cells are located throughout the body, resulting in many possible locations for the development of carcinoid tumor. The most common primary location is the gastrointestinal tract, followed by respiratory and thymic carcinoids. The presentations of these tumors are variable depending on their location, aggressiveness, production of functional peptides, and tendency to invade or metastasize. Carcinoid tumors can be imaged by various modalities including gastrointestinal studies, ultrasound, computed tomography, and magnetic resonance imaging as well as nuclear medicine studies (radioactive octreotide). In this review, we illustrate the spectrum of imaging features of carcinoid tumors in various locations of the human body.

Abstract
BACKGROUND Hepatic surgery is presumed to improve survival of patients with liver metastases (LM) from neuroendocrine tumours (NET). This study identified LM-specific variables that could be used as additional selection criteria for aggressive treatment. METHODS A novel classification of LM from NET was established based on their localization and presentation. RESULTS From 1992 to 2006, 119 patients underwent staging and treatment of LM. Three growth types of LM were identified radiologically: single metastasis (type I), isolated metastatic bulk accompanied by smaller deposits (type II) and disseminated metastatic spread (type III). The three groups differed significantly in terms of chronological presentation of LM, hormonal symptoms, Ki-67 index, 5-hydroxyindoleacetic acid and chromogranin A levels, lymph node involvement, presence of bone metastases and treatment options. The 3-, 5- and 10-year disease-specific survival rates for the entire cohort were 76.4, 63.9 and 46.5 per cent respectively. There were significant differences in survival between the three groups: 5- and 10-year rates were both 100 per cent for type I, 84 and 75 per cent respectively for type II, and 51 and 29 per cent for type III. CONCLUSION The localization and biological features of LM from NET defines therapeutic management and is predictive of outcome.

Abstract
Carcinoid tumours are neuroendocrine neoplasms that can appear in every location of the digestive tract. They are low aggressive tumours, although they often produce local invasion and hepatic metastases, whose resection allows long-term survival. We report a case of a 64-year-old man with ileal carcinoid tumour, that underwent ileal resection and metastasectomy of one lesion in liver segment II. Surgical findings indicated peritoneal carcinomatosis. Carcinoid dissemination as peritoneal carcinomatosis has been rarely described in the literature. Cytoreductive surgery, always when complete resection is aimed, achieves asymptomatic long-term survivals.

Abstract
BACKGROUND AND AIMS Little is known about the prognosis of patients with malignant digestive endocrine tumors (MDETs), primarily because of their rarity. METHODS Survival from these tumors has been evaluated in a large, well-defined, national population. All patients diagnosed and registered in England and Wales during the 14-year period from 1986 to 1999 were followed up for vital status to the end of 2001. Relative survival was estimated and the impact of age, sex, period, histology, and anatomic site modeled. RESULTS Among 4104 cases of MDETs, 21.2% were small cell tumors. Relative survival for all MDETs combined was 45.9% at 5 years and 38.4% at 10 years. Five-year survival was 56.8% for well-differentiated tumors but only 5.2% for small cell tumors (P < .0001). Survival was highest for large bowel tumors and lowest for esophageal tumors. Among well-differentiated pancreatic tumors, 5-year relative survival was 49.2% for insulinomas, 39.9% for gastrinomas, 17.1% for glucagonomas, 26.3% for carcinoid tumors, and 29.3% for nonfunctioning tumors. There was no difference in survival between socioeconomic groups. Five-year survival did not improve between 1986 and 2001. Survival was higher for women and for younger patients. Gender, age at diagnosis, and anatomic site were independent prognostic factors. CONCLUSIONS The prognosis of patients with MDETs in the general population is considerably worse than is often reported from small hospital case series. Prognosis varies with tumor differentiation, anatomic site, and histologic type. Early diagnosis is difficult; new therapeutic options appear to represent the best approach to improved prognosis.

Abstract
BACKGROUND Peritoneal carcinomatosis from a gastrointestinal carcinoid tumour is rare and the long-term management and prognosis have not been clearly defined. The natural history is different from gastrointestinal adenocarcinoma, although its capacity to invade regional lymph nodes and generate distal metastasis can make the management more complex. Whilst the development of carcinomatosis is uncommonly reported, it may be higher than expected. CASE PRESENTATION A 63 years-old woman underwent emergency surgery in 1993 for right iliac fossa pain and a mass that was found to be an ileal carcinoid tumour. Over the next ten years, further surgery was required for disseminated disease with peritoneal carcinomatosis and liver metastasis. Systemic chemotherapy had little effect, although Somatostatin was used effectively to relieve symptoms caused by the disseminated disease (flushing and diarrhoea). CONCLUSION Peritoneal carcinomatosis from carcinoid tumours is not well documented in the literature. Aggressive surgery must be performed in order to control the disease since chemotherapy has not been reported to be effective. With repeated surgery long-term survival can be achieved in these patients.

Abstract
Carcinoid tumors can present a difficult diagnostic and therapeutic dilemma. Despite their reputation as indolent tumors, they frequently metastasize and can cause significant symptomatology. The only curative therapy remains surgical resection. The prognosis and treatment of carcinoids vary based on location and histology, and therapy must be tailored to each patient.

Abstract
PURPOSE OF REVIEW Carcinoid tumors often present with metastatic disease. Generally, these tumors can be treated conservatively. New evidence exists, however, that stage IV disease may be better managed with more aggressive medical and surgical treatment. Headway is also being made into understanding the associated fibrosis seen with advanced disease and in better understanding signaling pathways with the hope of offering future treatment options. RECENT FINDINGS Recent literature has advocated for more aggressive surgical treatment of carcinoid tumors, especially in the setting of hepatic metastases and peritoneal carcinomatosis. Octreotide and lanreotide are further being described for treating metastatic carcinoids. Radiolabeled somatostatin analogues may prove to be as effective for treating carcinoids as for visualizing them. Other potential treatment modalities include pharmacologic activation of signaling pathways to control excess hormone production. Research into fibrosis - a cause of pain, bowel obstruction, retroperitoneal vascular constriction and right heart failure - has shown that serotonin and tachykinins may be the key mediators. SUMMARY Patients with stage IV carcinoid tumors may benefit from more aggressive surgical management and new treatment modalities. The growing body of knowledge regarding important molecular signaling pathway may lead to new medical therapies and further understanding of the sequelae of excess hormone production.
