Abstract
Pancreatic neuroendocrine tumors (p-NETs) are rare tumors with a recent growing incidence. In the 2017 WHO classification, p-NETs are classified into well-differentiated (i.e., p-NETs grade 1 to 3) and poorly differentiated neuroendocrine carcinomas (i.e., p-NECs). P-NETs G1 and G2 are often non-functioning tumors, of which the prognosis depends on the metastatic status. In the localized setting, p-NETs should be surgically managed, as no benefit for adjuvant chemotherapy has been demonstrated. Parenchymal sparing resection, including both duodenum and pancreas, are safe procedures in selected patients with reduced endocrine and exocrine long-term dysfunction. When the p-NET is benign or borderline malignant, this surgical option is associated with low rates of severe postoperative morbidity and in-hospital mortality. This narrative review offers comments, tips, and tricks from reviewing the available literature on these different options in order to clarify their indications. We also sum up the overall current data on p-NETs G1 and G2 management.

Abstract
Small-intestinal neuroendocrine tumors (SI-NETs) are the most prevalent small bowel neoplasms with an increasing frequency. In the multimodal management of SI-NETs, surgery plays a key role, either in curative intent, even if R0 resection is feasible in only 20% of patients due to advanced stage at diagnosis, or palliative intent. Surgeons must be informed about the specific surgical management of SI-NETs according to their hormonal secretion, their usual dissemination at the time of diagnosis and the need for bowel-preserving surgery to avoid short bowel syndrome. The aim of this paper is to review the surgical indications and techniques, and perioperative and postoperative management of SI-NETs.

Abstract
Surgical approaches to hepatic metastases occupy an important role in the management of patients with neuroendocrine neoplasms and may have curative or palliative intentions. Resection of hepatic disease with curative intent is the only modality offering potential cure for patients with liver metastases; however, only a minority of patients are eligible. Regardless of resection margin, disease recurrence almost invariably occurs and novel adjuvant/neoadjuvant therapies are mandated to be included within multimodal treatment concepts. Liver transplantation in meticulously selected patients may be associated with excellent outcomes, but unfortunately demands on donated organs limit the wider utilization of this approach.

Abstract
BACKGROUND Pancreatic neuroendocrine tumors (PNETs) are rare pancreatic neoplasms. About 40-80% of patients with PNET are metastatic at presentation, usually involving the liver (40-93%). Liver metastasis represents the most significant prognostic factor. The aim of this study is to present an up-to-date review of treatment options for patients with liver metastases from PNETs. METHODS A systematic literature search was performed using the PubMed database to identify all pertinent studies published up to May 2018. RESULTS The literature search evaluated all the therapeutic options for patients with liver metastases of PNETs, including surgical treatment, loco-regional therapies, and pharmacological treatment. All the different treatment options showed particular indications in different presentations of liver metastases of PNET. Surgery remains the only potentially curative therapeutic option in patients with PNETs and resectable liver metastases, even if relapse rates are high. Efficacy of medical treatment has increased with advances in targeted therapies, such as everolimus and sunitinib, and the introduction of radiolabeled somatostatin analogs. Several techniques for loco-regional control of metastases are available, including chemo- or radioembolization. CONCLUSIONS Treatment of patients with PNET metastases should be multidisciplinary and must be personalized according to the features of individual patients and tumors.

Abstract
Neuroendocrine tumors (NET) represent the variability of almost benign lesions either secreting hormones occurring as a single lesion up to malignant lesions with metastatic potential. Treatment of NET is usually performed by surgical resection. Due to the rarity of NET, surgical treatment is mainly based on the experience and recommendations of experts and less on the basis of prospective randomized studies. In addition, the development and establishment of new surgical procedures is made more difficult by their rarity. The development of laparoscopic-assisted surgery has significantly improved the treatment of many diseases. Due to the well-known advantages of laparoscopic surgery, this method has also been increasingly used to treat NET. However, due to limited comparative data, the assumed superiority of laparoscopic surgery in the area NET remains often unclear or not yet proven. This review focuses on the present usage of laparoscopic techniques in the area of NET. Relating to the current literature, this review presents the evidence of various laparoscopic procedures for treatment of adrenal, pancreatic and intestine NET as well as extraadrenal pheochromocytoma and neuroendocrine liver metastases. Further, this review focuses on recent new developments of minimally invasive surgery in the area of NET. Here, robotic-assisted surgery and single-port surgery are promising approaches.

Abstract
BACKGROUND Patients with metastatic neuroendocrine cancers to the liver often present with disabling endocrinopathies and pain associated with bulky disease. Quality of life for these patients is poor and can require long-term therapy with somatostatin analogs for control of their symptoms. Alternative therapies to decrease tumor burden and subsequent hormone release have been investigated. Of these, cytoreductive surgery was found to have the most consistent and profound impact on symptom regression and overall survival. METHODS Several cases are reported that illustrate an aggressive multimodality approach in the treatment of metastatic neuroendocrine cancers to the liver. The literature is reviewed and the role of cytoreductive surgery in the management of hepatic neuroendocrine metastases is discussed. RESULTS Cytoreductive surgery can be performed safely with minimal morbidity and mortality. Regression of symptoms occurs in the majority of patients and survival is prolonged. CONCLUSIONS Surgical intervention as part of an aggressive multimodality treatment plan results in improved outcomes for patients with advanced hepatic metastases of neuroendocrine origin. Future directions may include earlier surgical intervention with adjuvant therapies reserved for aggressive recurrent disease.

Abstract
The remnant liver's ability to regenerate may affect post-hepatectomy immediate mortality. The promotion of autophagy post-hepatectomy could enhance liver regeneration and reduce mortality. This study aimed to identify predictive factors of immediate mortality after surgical resection for hepatocellular carcinoma (HCC). A total of 535 consecutive HCC patients who had undergone their first surgical resection in Taiwan were enrolled between 2010 and 2014. Clinicopathological data and immediate mortality, defined as all cause-mortality within three months after surgery, were analyzed. The expression of autophagy proteins (LC3, Beclin-1, and p62) in adjacent non-tumor tissues was scored by immunohistochemical staining. Approximately 5% of patients had immediate mortality after surgery. The absence of LC3, hypoalbuminemia (<3.5 g/dl), high alanine aminotransferase, and major liver surgery were significantly associated with immediate mortality in univariate analyses. Multivariate logistic regression demonstrated that absence of LC3 (hazard ratio/95% confidence interval: 40.8/5.14-325) and hypoalbuminemia (2.88/1.11-7.52) were significantly associated with immediate mortality. The 3-month cumulative incidence of mortality was 12.1%, 13.0%, 21.4% and 0.4%, respectively, among patients with absence of LC3 expression, hypoalbuminemia, both, or neither of the two. In conclusion, the absence of LC3 expression in adjacent non-tumor tissues and hypoalbuminemia were strongly predictive of immediate mortality after resection for HCC.

Abstract
OBJECTIVES to determine the prognostic factors that may impact on morbidity and mortality and survival of patients undergoing surgical treatment of liver metastases from neuroendocrine tumors. METHODS We studied 22 patients undergoing liver resection for metastases from neuroendocrine tumors between 1997 and 2007. Epidemiological and clinical data were correlated with morbidity and mortality and overall and disease-free survivals. RESULTS twelve patients were male and ten female, with a mean age of 48.5 years. Bilobar disease was present in 17 patients (77.3%). In ten patients (45.5%) the primary tumor originated in the pancreas, terminal ileum in eight, duodenum in two, rectum in one and jejunum in one. Complete surgical resection (R0) was achieved in 59.1% of patients. Eight patients (36.3%) developed complications in the immediate postoperative period, one of them dying from septicemia. All patients undergoing re-hepatectomy and/or two-stage hepatectomy had complications in the postoperative period. The overall survival at one and five years was 77.3% and 44.2%. The disease-free survival at five years was 13.6%. The primary pancreatic neuroendocrine tumor (p = 0.006) was associated with reduced overall survival. Patients with number of metastatic nodules < 10 (p = 0.03) and asymptomatic at diagnosis (p = 0.015) had higher disease-free survival. CONCLUSION liver metastases originating from pancreatic neuroendocrine tumors proved to be a negative prognostic factor. Symptomatic patients with multiple metastatic nodules showed a significant reduction in disease-free survival.

Abstract
Hepatic metastases are one of the most important prognostic factors for survival among patients affected by gastrointestinal neuroendocrine tumors (NETs). The present study aims to evaluate the impact of surgery, including hepatic resection or orthotopic liver transplantation (OLT), on the outcome of patients affected by hepatic metastases from NETs, in terms of overall survival (OS). In this multicentric retrospective study, data was collected on 26 patients, who underwent surgery for hepatic metastases from NETs in two Italian University Clinics between January 1990 and December 2012; of which, 22 patients underwent hepatic resective surgery and 4 patients OLT. Hepatic metastases were synchronous in the 53.8% of cases and metachronous in the 46.2% of cases. The median number of resected hepatic metastases was 3. Surgical radicalness (R0) was reached in the 84.6% of cases. In total, 57.7% of patients had a recurrence, 66.7% of which were intra- and 33.3% extra-hepatic. The OS of patients that underwent hepatic resections and OLT was 44.9% [95% confidence interval (CI95), 26.0-77.7%] and 50% (CI95, 12.5-100.0%) at 5 years, respectively. Although the data regarding the survival of patients receiving surgery for hepatic metastases from NETs are encouraging, randomized clinical trials are necessary to more adequately evaluate the effect of surgery on survival of this group of patients.

Abstract
During the last decades an increase in the incidence of neuroendocrine tumors (NETs) was observed. Gastroenteropancreatic NETs represent the majority of NETs. Compared with their epithelial counterpart they usually have a more indolent behaviour and surgical resection improves survival. Tumor diameter is one of the main parameter in the decision making process for nonfunctioning forms. Generally, small lesions can be treated conservatively whereas larger tumors should be treated with standard surgical resection and lymphadenectomy. Functioning tumors should be resected regardless the dimension of the lesion. Locally advanced and metastatic disease should be also treated with extended resections, keeping in consideration the grading, size, Ki67, and presence of extra-abdominal disease. In the case of metastases the panel of operative treatment includes resection, ablation, up to liver transplantation.

Abstract
Pancreatic neuroendocrine tumors (pNETs) are rare and comprise only 1-2 % of all pancreatic neoplastic disease. Although the majority of these tumors are sporadic (90 %), pNETs can arise in the setting of several different hereditary genetic syndromes, most commonly multiple endocrine neoplasia type 1 (MEN1). The presentation of pNETs varies widely, with over 60 % having malignant distant disease at the time of initial diagnosis involving the liver or other distant sites. Functioning pNETs represent approximately 10 % of all pNETs, secrete a variety of peptide hormones, and are responsible for several clinical syndromes caused by profound hormonal derangement. Surgery remains the cornerstone of therapy and the only curative approach. It should be pursued for localized disease and for metastatic lesions amenable to resection. Multimodality therapies, including liver-directed therapies and medical therapy, are gaining increasing favor in the treatment of advanced pNETs. Their utility is multifold and spans from ameliorating symptoms of hormonal excess (functional pNETs) to controlling the local and systemic disease burden (non-functional pNETs). The recent introduction of target molecular therapy has promising results especially for the treatment of progressive well-differentiated G1/G2 tumor. In this review, we summarize the current knowledge and give an update on recent advancements made in the therapeutic strategies for pNETs.

Abstract
Pancreatic neuroendocrine tumors (pNETs) are relatively rare tumors comprising 1-2% of all pancreas neoplasms. In the last 10 years our understanding of this disease has increased dramatically allowing for advancements in the treatment of pNETs. Surgical excision remains the primary therapy for localized tumors and only potential for cure. New surgical techniques using laparoscopic approaches to complex pancreatic resections are a major advancement in surgical therapy and increasingly possible. With early detection being less common, most patients present with metastatic disease. Management of these patients requires multidisciplinary care combining the best of surgery, chemotherapy and other targeted therapies. In addition to surgical advances, recently, there have been significant advances in systemic therapy and targeted molecular therapy.

Abstract
Patients who have neuroendocrine tumors frequently present with liver metastases. A wide panel of treatment options exists for these patients. Liver resection with curative intent achieves the best long-term results. Highly selected patients may be considered for liver transplantation. Substantial recurrence rates reported after surgical approaches call for neoadjuvant and adjuvant concepts. Liver-directed, locally ablative procedures are recommended for patients with limited, nonresectable tumor burden. Angiographic liver-directed techniques, such as transarterial embolization, transarterial chemoembolization, and selective internal radiotherapy, offer excellent palliation for patients with liver-predominant disease. Peptide receptor radionuclide therapy is a promising palliative procedure for patients with hepatic and/or extrahepatic metastases. The efficacy of these treatment options needs to be evaluated in randomized trials. Somatostatin analogues have demonstrated effectiveness not only for symptomatic relief in patients with secreting tumors but also for the control of proliferation in small intestinal neuroendocrine tumors and most recently also in those originating from the pancreas. Chemotherapy is an option mainly for those with pancreatic neuroendocrine tumors and high-grade tumors irrespective of the origin. Novel drugs targeting specific pathways within the tumor cell have produced improved progression-free survival compared with placebo in patients with pancreatic neuroendocrine tumors. Despite such a diverse armamentarium, there is uncertainty with regard to the optimal treatment regimens. Newly introduced molecular-based markers, along with the conduction of clinical trials comparing the efficacy of treatment modalities, offer a chance to move the treatment of neuroendocrine tumor disease toward personalized patient care. In this report, the authors review the approaches for treatment of neuroendocrine liver metastases, identify shortcomings, and anticipate future perspectives. Furthermore, clinical practice recommendations are provided for currently available treatment options. Although multiple modalities are available for the treatment of neuroendocrine liver metastases, optimal management is unclear. The current knowledge pertaining to these treatment options is analyzed.

Abstract
The incidence of neuroendocrine tumors (NETs) has increased in the last decades. Surgical treatment encompasses a panel of approaches ranging from conservative procedures to extended surgical resection. Tumor size and localization usually represent the main drivers in the choice of the most appropriate surgical resection. In the presence of small (<2 cm) and asymptomatic nonfunctioning NETs, a conservative treatment is usually recommended. For localized NETs measuring above 2 cm, surgical resection represents the cornerstone in the management of these tumors. As they are relatively biologically indolent, an extended resection is often justified also in the presence of advanced NETs. Surgical options for NET liver metastases range from limited resection up to liver transplantation. Surgical choices for metastatic NETs need to consider the extent of disease, the grade of tumor, and the presence of extra-abdominal disease. Any surgical procedures should always be balanced with the benefit of survival or relieving symptoms and patients' comorbidities.

Abstract
BACKGROUND Liver metastases are a strong prognostic indicator in patients with gastro-entero-pancreatic neuroendocrine tumors (GEP-NETs). Therapeutic options for metastatic NETs are expanding and not mutually exclusive. AIMS This paper reviews the literature relating to multidisciplinary approach towards GEP-NET metastases, to highlight advances in knowledge regarding these tumors, and to understand the interdisciplinary management of individual patients. METHODS A PubMed search was performed for English-language publications from 1995 through 2012. Reference lists from studies selected were manually searched to identify further relevant reports. Manuscripts comparing different therapeutic options and advances for GEP-NET-related liver metastases were selected. RESULTS There is considerable controversy regarding the optimal management of GEP-NET metastases. Although radical surgery still remains the gold standard, a variety of other therapeutic options are available for metastatic GEP-NETs, including loco-regional chemotherapy/radiotherapy, radioembolization, systemic peptide receptor radionuclide therapy, biotherapy, and chemotherapy. In selected patients, liver transplantation should also be considered. Systemic somatostatin analogues and/or interferon show anti-proliferative effects, representing an appropriate first-line treatment for most patients. In advanced metastatic NETs, recent options include targeted therapies (i.e., everolimus and sunitinib). CONCLUSIONS It is evident that multidisciplinary care and multimodality treatments remain the cornerstone of management of NET patients. Since NETs often show a more indolent behavior compared to other malignancies, physicians should aim to preserve a satisfactory quality of life for the patient by personalizing the therapeutic approach according to the tumor's features and prognostic factors.

Abstract
Introduction. The literature on reoperation following pancreaticoduodenectomy is sparse and does not address all concerns.
Aim. To analyze the incidence, causes, and outcome of patients undergoing reoperations following pancreaticoduodenectomy.
Methods. Retrospective analysis of 520 consecutive patients undergoing pancreaticoduodenectomy from May 1989 to September 2010.
Results. 96 patients (18.5%) were reoperated; 72 were early, 18 were late, and 6 underwent both early and late reoperations. Indications for early reoperation were post pancreatectomy hemorrhage in 53 (68%), pancreatico-enteric anastomotic leak in 10 (13%), hepaticojejunostomy leak in 3 (3.8%), duodenojejunostomy leak in 4 (5%), intestinal obstruction in 1 (1.2%) and miscellaneous causes in 7 (9%). Patients reoperated early did not fare poorly on long-term follow up. Indications for late reoperations were complications of index surgery (n = 12), recurrence of the primary disease (n = 8), complications of adjuvant radiotherapy (n = 3), and gastrointestinal bleed (n = 1). The median survival of 16 patients reoperated late without recurrent disease was 49 months.
Conclusion. Early reoperations following pancreaticoduodenectomy, commonly for post pancreatectomy hemorrhage, carries a high mortality due to associated sepsis, but has no impact on long-term survival. Long-term complications related to pancreaticoduodenectomy and adjuvant radiotherapy can be managed successfully with good results.

Abstract
BACKGROUND Neuroendocrine tumours (NET) most commonly metastasize to the liver. Hepatic resection of NET hepatic metastases (NETHM) has been shown to improve symptomology and survival. METHODS A systematic review of clinical studies before September 2010 was performed to examine the efficacy of hepatic resection for NETHM. As a secondary end-point, the impact of treatment on safety and symptomology were determined and prognostic variables were identified. The quality of each study was also assessed using predefined criteria incorporating 9 characteristics. Clinical outcome was synthesized through a narrative review with full tabulation of results of all included studies. RESULTS Twenty-nine included reported survival outcomes with a median 3-, 5- and 10-year overall survival of 83% (range, 63-100%), 70.5% (range, 31-100%), and 42% (range, 0-100%), respectively. The median progression-free survival (PFS) was 21 months (range, 13-46 months) and median 1-,3-,5- and 10-year PFS of 63% (range, 50-80 %), 32% (range, 24-69%), 29% (range, 6-66%) and 1% (range, 0-11%), respectively. Poor histologic grade, extra-hepatic disease and a macroscopically incomplete resection were associated with a poor prognosis. Studies reported a median rate of symptomatic relief from surgery in 95% of patients (range, 50-100%). CONCLUSION Hepatic resection for NETHM provides symptomatic benefit and is associated with favourable survival outcomes although the majority of patients invariably develop disease progression.

Abstract
Liver resection is considered the therapeutic gold standard for primary and metastatic liver neoplasms. The reduction of postoperative complications and mortality has resulted in a more aggressive approach to hepatic malignancies. For the most part, results of liver surgery have been published by highly experienced institutions, but the observations of highly specialized units results may not reflect the current status of hepatic surgery, underestimating mortality and complications. The objective of this study is to evaluate morbidity and mortality as a result of liver resection for primary and metastatic lesions, analyzing a large number of studies with a meta-analytic process taking into account the overdispersion of data. An extensive literature search has been conducted, and 148 papers published between January 2000 and April 2008, including a total of 36,629 patients from both high-volume and low volume institutions, were included in the meta-analysis. A beta binomial model was used to provide a robust estimate of the summary event rate by pooling overdispersion binomial data from different studies. Overall morbidity and mortality after liver surgery were 29.32 per cent and 3.15 per cent, respectively. Significantly higher postoperative mortality was observed after liver resection for hepatocellular carcinomas and primary hepatic tumors. The application of a beta binomial model to correct for overdispersion of liver surgery data showed significantly higher postoperative mortality rates in patients with hepatocellular carcinomas or primary hepatic tumors after liver resection.

Abstract
Neuroendocrine neoplasms (NENs) are a distinctive entity, and nearly 10% of patients already have liver metastases at presentation. The management of neuroendocrine liver metastases (NEN-LM) is complex with differing patterns of metastatic presentation. An aggressive approach should be used to resect the primary tumor, to remove regional lymph nodes, and to resect or treat appropriate distant metastases (including liver tumors). Despite having an indolent course, NENs have a significantly reduced survival when liver metastases are untreated. Though a wide range of therapies are now available with a multimodal approach to the treatment, surgical treatment offers the only chance for a significant survival prolongation and/or improvement of symptoms and quality of life. A review of the existing surgical modalities for NEN-LM is discussed in this paper.

Abstract
Management of Neuroendocrine liver metastases (NELM) is challenging. The presence of NELM worsens survival outcome and almost 10% of all liver metastases are neuroendocrine in origin. There is no firm consensus on the optimal treatment strategy for NELM. A systematic search of the PubMed database was performed from 1995-2010, to collate the current evidence and formulate a sound management algorithm. There are 22 case series with a total of 793 patients who had undergone surgery for NELM. The overall survival ranges from 46-86% at 5 years, 35-79% at 10 years, and the median survival ranges from 52-123 months. After successful cytoreductive surgery, the mean duration of symptom reduction is between 16-26 months, and the 5-year recurrence/progression rate ranges from 59-76%. Five studies evaluated the efficacy of a combination cytoreductive strategy reporting survival rate of ranging from 83% at 3 years to 50% at 10 years. To date, there is no level 1 evidence comparing surgery versus other liver-directed treatment options for NELM. An aggressive surgical approach, including combination with additional liver-directed procedures is recommended as it leads to long-term survival, significant long-term palliation, and a good quality of life. A multidisciplinary approach should be established as the platform for decision making.

Abstract
Patients with neuroendocrine tumours (NETs) are best managed in a specialist centre as part of a multidisciplinary team comprising gastroenterologists, oncologists, endocrinologists, gastrointestinal and hepatopancreaticobiliary surgeons, pathologists, nuclear medicine physicians and technicians, radiologists, specialist nurses, pharmacists, biochemists and dieticians. This should ideally be led by a clinician with experience and interest in NETs. Although the number of medical treatments and clinical trials has increased in the decade, there is still a lack of prospective randomised trials; thus, management is mainly based on limited often single-centre studies, although there are now formal guidelines based on consensus expert opinion. We have outlined the current optimal management of patients with NETs. We have reviewed therapeutic options including surgery, somatostatin analogues and other biotherapies and peptide receptor-targeted therapy. We have discussed the challenge in managing hepatic metastases including hepatic artery embolisation, ablation and orthotopic liver transplant. In addition, we have briefly reviewed the emerging therapies such as the mammalian target of rapamycin and angiogenic inhibitors and the newer somatostatin analogues.

Abstract
BACKGROUND Hepatic resection of metastatic carcinoid cancer can prolong survival and control symptomatic endocrinopathy. Decompensated carcinoid heart disease (CHD) can develop in some patients with metastatic carcinoid cancers, which can preclude operation for resectable hepatic metastases. We hypothesized that outcomes after hepatic resection for patients with the carcinoid syndrome after valve replacement for CHD would be similar to carcinoid patients without CHD. STUDY DESIGN We compared the survival and symptom control after hepatic resection for patients undergoing valve replacement for CHD to carcinoid patients without CHD matched for age, sex, and extent of hepatectomy. RESULTS Fourteen patients with earlier valve replacement for CHD were compared with 28 carcinoid patients without CHD. All patients had hepatic resection for metastatic carcinoid disease and carcinoid syndrome. Mean age, sex distribution, and extent of hepatectomy (major hepatectomy, 78%) was similar between groups. Mean interval from valve replacement to hepatectomy was 101 days. There was no operative mortality. Major operative morbidity, inclusive of operative blood loss and cardiorespiratory events, occurred in 28.5% and 14.2% for CHD and non-CHD groups, respectively (p = 0.16). Symptom-free survival for CHD and non-CHD groups was 69% and 81% at 1 year (p = 0.22) and 61% and 44% (p = 0.17) at 5 years, respectively. Octreotide-free survival after hepatectomy 69% and 84% (p = 0.15) at 1 year and 62% and 52% (p = 0.29) 5 years, respectively. Overall survival CHD and non-CHD groups 100% at 1 year and 100% and 70% (p = 0.002) 5 years. CONCLUSIONS Valve replacement for severe CHD is safe and hepatic resection is associated with similar outcomes as patients without CHD undergoing hepatic resection for carcinoid syndrome. Identifying resectable hepatic metastases from carcinoids in patients with severe CHD should prompt valve replacement and interval hepatic resection.

Abstract
BACKGROUND The incidence of neuroendocrine tumours (NET) has increased over the past three decades. Hepatic metastases which occur in up to 75% of NET patients significantly worsen their prognosis. New imaging techniques with increasing sensitivity enabling tumour detection at an early stage have been developed. The treatment encompasses a panel of surgical and non-surgical modalities. METHODS This article reviews the published literature related to management of hepatic neuroendocrine metastases. RESULTS Abdominal computer tomography, magnetic resonance tomography and somatostatin receptor scintigraphy are widely accepted imaging modalities. Hepatic resection is the only potentially curative treatment. Liver transplantation is justified in highly selected patients. Liver-directed interventional techniques and locally ablative measures offer effective palliation. Promising novel therapeutic options offering targeted approaches are under evaluation. CONCLUSIONS The treatment of neuroendocrine liver metastases still needs to be standardized. Management in centres of expertise should be strongly encouraged in order to enable a multidisciplinary approach and personalized treatment. Development of molecular prognostic factors to select treatment according to patient risk should be attempted.

Abstract
Liver metastases from endocrine tumors can reduce 5-year survival from 90% to 40% and, in cases of functional gastrointestinal endocrine tumors, lead to a carcinoid syndrome. Complete resection of cancerous disease should be considered in all cases. Indeed, after hepatectomy, prolonged survival (41-86% at five years) can be achieved, with low rates of surgery-related mortality (0-6.7%). Extended liver resection is required in most cases. Percutaneous portal embolization increases the volumetric feasibility of resection, and sequential hepatectomy techniques enable a two-stage resection of both bilobar metastases and the primary tumor. For carcinoid syndrome that does not respond to medical therapy, incomplete resection of liver metastases, by reducing tumor volume, may be indicated to reduce symptoms and halt the progression of carcinoid heart disease. In cases of non-resectable liver metastases in selected patients, liver transplantation can lead to 5-year survival rates as high as 77%.

Abstract
The indolent nature of neuroendocrine tumors and their proclivity to be hormonally active warrant aggressive treatment for advanced stage disease with hepatic metastases. Cytoreduction has been associated with improved symptom control as well as prolonged survival compared with those treated with medical therapy. The primary modalities of cytoreduction employed are resection, ablation, and embolization. In particular, radiofrequency ablation has been utilized with good results and minimal morbidity for treating patients with advanced neuroendocrine disease.

Abstract
Neuroendocrine malignancies encompass a variety of tumors that differ considerably in origin, hormonal activity, and biological behavior. Because of their rarity most therapeutic recommendations have been based on limited evidence from small retrospective series observing miscellaneous patient cohorts. Only in recent years proposals for TNM and histological grading systems have been elaborated that allow further stratification of patients suffering from these tumors. Especially patients with well and moderately differentiated neuroendocrine malignancies benefit from resection of liver metastases, improving the 5-year survival rate from <50% to 80%. Orthotopic liver transplantation can likewise improve survival in carefully selected patients. New developments in imaging modalities, intensive care treatment, and in liver surgery itself have broadened the selection of potentially resectable tumors.

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
Patients with gut-based metastatic neuroendocrine tumors (NET) often present late in the course of their slowly progressive disease, when cancer has extended beyond the point of reasonable expectation for surgical cure. At this stage of disease, the tumor's overwhelming hormonal production often significantly impairs the patient's quality of life. Unlike patients with other malignancies that might involve a heavy burden of hepatic metastatic disease, many patients with metastatic NET continue to live for a long time despite escalating hormone-related symptoms. This establishes the justification and rationale for cytoreduction, a noncurative surgical intervention that reduces tumor burden and hormonal burden and thereby can significantly increase symptom-free survival in the setting of an often slow but inevitable disease progression.

Abstract
OBJECTIVE We describe the early and distant results of a 2-step surgical strategy that enables complete resection in selected patients with primary digestive endocrine tumors (DET) and synchronous bilobar liver metastases (LM). BACKGROUND Frequent synchronous and bilobar liver involvement limits indications of surgery in LM from DET. STUDY DESIGN From 1996 to 2004, of 41 patients with synchronous bilobar LM from DET, 23 (56%) were selected for 2-step surgery. The first step included resection of the primary tumor and limited (nonanatomic) resection of left LM (segments 1-4) associated with a right portal vein ligation. After 8 weeks, following hypertrophy of the cleared left liver, a right or extended right hepatectomy was planned. RESULTS At the first step, all primary tumors (bowel = 12, distal pancreas = 10, rectal = 1) were resected and LM were resected in 20 patients (87%). One patient did not have second-step due to tumor progression. The second step (n = 19; 83%) was performed after a median interval of 8 weeks (range, 6-13) and a 54 +/- 21% mean left liver hypertrophy rate. Postoperatively, 4 (17%) and 4 (21%) patients developed nonlethal complications and the median hospital stay was 11 (range, 7-26) and 13 (range, 9-17) days after the first and the second step, respectively. The median number of resected LM was 4 (range, 1-9) and 7 (range, 4-17), respectively. With a median follow-up of 64 months (range, 6-122), of the 19 patients who had complete 2-step surgery, all except one are alive. The 2-, 5-, and 8-year Kaplan-Meier overall and disease-free survival rates were 94%, 94%, 79% and 85%, and 50% and 26%, respectively. CONCLUSIONS This 2-step surgery approach enables complete resection with no mortality, acceptable morbidity, and good long-term survival in selected patients with synchronous bilobar LM from DET.

Abstract
The liver is the most common site of metastatic disease from both gastrointestinal and extra-intestinal malignancies. Historically, only a minority of patients with colorectal liver metastases were candidates for resection. However, over the past several decades, liver resection has evolved as a safe and potentially curative treatment for hepatic colorectal metastases. The development of active chemotherapy and molecular targeted therapies, together with newer modalities like radiofrequency ablation, have expanded the indications for hepatic resection and improved survival. Selected patients with isolated liver metastases from neuroendocrine tumors, germ cell cancers, ocular melanoma, gastrointestinal stromal tumors (GIST), and breast cancer also may be considered for hepatic surgery.

Abstract
Peptide receptor radionuclide therapy is a new therapeutic modality for patients with nonresectable neuroendocrine tumors. The technique is based on the unique ability of these tumors to express cell membrane-specific peptide receptors that can be targeted with radiolabeled somatostatin analogues. A high level of uptake on somatostatin receptor scintigraphy is a prerequisite for effective treatment. The efficacy of this method has been proven in several clinical trials. In a substantial number of patients, an improvement of life quality has been achieved in addition to a marked morphologic and biochemical tumor response. Serious side effects are rarely observed. Attention must be paid to kidney protection during the treatment. The present review summarizes the clinical experience with the treatment of advanced neuroendocrine tumors with radiolabeled somatostatin analogues and focuses on patient selection and the appropriate timing of the therapy. Finally, it emphasizes treatment-related issues that deserve attention in the future.

Abstract
Treatment options for primary and secondary liver tumors that cannot be resected or ablated are based on transarterial techniques. Although the majority of these are based on bland and chemoembolization techniques, yttrium-90 microspheres represent an alternate transarterial option. Although the amount of literature on (90)Y does not rival that of bland or chemoembolization, there nevertheless are ample data that support its use for primary and metastatic liver tumors. A comprehensive review of the entire available literature dating from the early 1960s is presented, as is a discussion of the possibilities for future research with use of radioembolization as a platform.

Abstract
BACKGROUND Surgical resection has been advocated as an effective treatment for hepatic neuroendocrine tumors (HNETs) in Western countries, but few data are available to define its indications. We evaluated the results of Japanese patients to determine the prognostic factors and the feasibility of our aggressive surgical approach. METHODS The records of all consecutive patients who underwent surgical resection for HNETs at our institution were retrospectively reviewed. Patients were selected for surgery if all tumors were deemed resectable, regardless of their extent. RESULTS A total of 21 patients were identified. Bilobar disease was present in 13 patients (62%). Eleven patients (52%) underwent major hepatectomy, which included right trisectionectomy, extended right or left hepatectomy and right hepatectomy. No in-hospital death occurred. The overall 1-, 3- and 5-year survival rates were 95, 68 and 41%, respectively, with a median follow-up of 34 months. Metastatic HNETs from bronchopulmonary primaries exhibited significantly poor outcome compared with other primary sites (P = 0.04). Patients who underwent curative resection had an improved overall 5-year survival rate of 73% compared with palliative resection (0%, P = 0.01). The longest survival in the latter group was 57 months. Complete symptom resolution rate was 92%. CONCLUSIONS This is the first study from Asia demonstrating the safety of aggressive hepatic resection for HNETs. Significant symptom relief and long-term survival were achieved irrespective of the extent of disease or the magnitude of operation. Metastatic HNETs from bronchopulmonary primaries may represent a more lethal subset of tumors.

Abstract
BACKGROUND Treatment modalities for hepatic metastases from neuroendocrine tumours (NETs) include surgery, somatostatin analogues and arterial embolization. The aims of this study were to evaluate the outcome of patients following surgery and to identify prognostic predictors of recurrent disease. PATIENTS AND METHODS This was a retrospective clinico-pathological analysis of patients managed with hepatic NET metastases over a 13-year period (January 1994 to December 2006). RESULTS Eighteen patients with hepatic metastases from NET were identified with a median age of 53 years (range 31-75). The localization of the primary tumour was the terminal ileum (n=8), pancreas (n=7), appendix (n=2) or duodenum (n=1). Twelve patients had synchronous disease and six patients developed metachronous hepatic tumours over a median period of 20 months (range 6-144). Presenting symptoms included abdominal pain (n =13), recurrent diarrhoea (n=7) and flushing (n=7). Fifteen patients underwent surgery with complete cytoreduction and three patients had partial cytoreduction. The overall 2- and 5-year actuarial survival rates were 94% and 86%, respectively. The 2- and 5-year disease-free rates following hepatic resection with complete cytoreduction were both 66%. Partial or complete control of endocrine-related symptoms was achieved in all patients with functioning tumours following surgery. Recurrent disease occurred in four patients following complete cytoreductive surgery. Resection margin involvement was associated with developing recurrent disease (p=0.041). CONCLUSION Surgical resection for hepatic NET metastases results in good long-term survival in selected patients and resection margin involvement was associated with recurrent disease.

Abstract
The development of hepatic metastases (HM) marks a turning point in the evolutionand prognosis of well-differentiated endocrine tumors (ET). Management is usually multicisciplinary (chemotherapy, arterial chemo-embolization, percutaneous ablation, somatostatin analogs, biotherapy, and surgery). A thorough pre-operative work-up is neecessary to exclude extrahepatic disease and to detect tiny HM's. Complete resection (RO) is the only curative treatment for well-differentiated ET with HM. The type of resection is specific to each case and may range from wedge resection of a metastasis to complex hepatectomy with simultaneous resection of the primary ET. Cytoreductive surgery may be indicated for palliation when medical therapy fails to control endocrine symptoms. Operative mortality is low (0-6%) and global survival is 60-70% afterafter R) resection of HM of well-differentiated ET's. After resection of HM involving only one hepatic lobe, 5 year survival is better than 90%. When HM are multiple, bilobar and synchronous, the prognosis is very poor--only 10% of such patients can have a complete resection and this often requires a long prologue of ancillary procedures (chemotherapy, chemoembolization, portal vein ligation, percutaneous ablation). Hepatic transplantation (HT) has only a limited rôle in the treatment of HM for ET; mortality is high when HT is associated with large and complex resections, i.e. pancreaticoduodenectomy. Although there is no consensus in the literature, HT should be limited to the most optimal cases (young, good general health, well-differentiated tumor, slow evolution, complete resection of the primary rumor, and unresectable liver metastases). Global survival for HT in patients with ET is 60% at 2 years, 47% at 5 years; tumor-free survival at 5 years is 24%. HT for HM has better survival results for ET's of intestinal origin (carcinoids) than for duodenopancreatic ET's.

Abstract
Endocrine tumors (ET) of the digestive tract (formerly called neuroendocrine tumors) are rare. They are classified into two principal types: gastrointestinal ET's (formerly called carcinoid tumors) which are the most common, and pancreaticoduodenal ET's. Functioning ET's secrete polypeptide hormones which cause characteristic hormonal syndromes. The management of ET is multidisciplinary. Poorly-differentiated ET's have a poor prognosis and are treated by chemotherapy. Surgical excision is the only curative treatment of well-differentiated ET's. The surgical goals are to: 1. prolong survival by resecting the primary tumor and any nodal or hepatic metastases, 2. control the symptoms related to hormonal secretion, 3. prevent or treat local complications. The most common sites of gastrointestinal ET's ( carcinoids) are the appendix and the rectum; these are often small (<1 cm), benign, and discovered fortuitously at the time of appendectomy or colonoscopic removal. Ileal ET's, even if small, are malignant, frequently multiple, and complicated in 30-50% of cases by bowel obstruction, mesenteric invasion, or bleeding. The carcinoid syndrome (consisting of abdominal pain, flushing, diarrhea, hypertension, bronchospasm, and right sided cardiac vegetations) is caused by the hypersecretion of serotonin into the systemic circulation; it occurs in 10% of cases and is usually associated with hepatic metastases. More than half of the cases of pancreatic ET are non-functional. They are usually malignant and of advanced stage at diagnosis presenting as a palpable or obstructing mass or as liver metastases. Insulinoma and gastrinoma (cause of the Zollinger-Ellison syndrome) are the most common functional ET's. 80% are sporadic; in these cases, tumor size, location, and malignant potential determine the type of resection which may vary from a simple enucleation to a formal pancreatectomy. In 10-20% of cases, pancreaticoduodenal ET presents in the setting of multiple endocrine neoplasia (NEM type I), an autosomal-dominant genetic disease with multifocal endocrine involvement of the pituitary, parathyroid, pancreas, and adrenal glands. For insulinoma with NEM-I, enucleation of lesions in the pancreatic head plus a caudal pancreatectomy is the most appropriate procedure. For gastrinoma with NEM-I, the benefit of surgical resection for tumors less than 2-3 cm in size is not clear. The lesions are frequently small, multiple, and widespread and recurrence is frequent after excision. The long-term prognosis is nevertheless fairly good. But the eventual development of liver metastases which are the most common cause of mortality still argues for an aggressive surgical approach in the early stages of the disease.

Abstract
Patients with neuroendocrine tumours often present with synchronous liver metastases or develop hepatic metastases in the course of their disease. A complete removal of liver metastases with an intention to cure may be accomplished by liver resection or, if hepatic disease is disseminated or hormonal symptoms and pain cannot be controlled medically, by total hepatectomy and transplantation. The indications for orthotopic liver transplantation for metastatic neuroendocrine tumour disease should be anchored in a multimodal and multidisciplinary therapeutic approach. Approximately, 120-130 cases of orthotopic liver transplantation for neuroendocrine tumours have been published so far, but follow-up after transplantation has been limited, and most reports comprise a small number of patients. After considering published studies and data, some recommendations may be given, although these are based on a low level of evidence. After excluding extrahepatic tumour manifestations by imaging procedures and diagnostic laparoscopy, the indication should be chosen restrictively. Few prognostic markers, for example age below 50 years and absence of concurrent extensive surgery, were identified by multivariate analysis in a large retrospective analysis. The prognostic impact of primary tumour localisation is still controversial. However, further indicators of favourable long-term prognosis are needed. Tumour biology characterised by Ki67 and E-cadherin expression may help to identify patients with a favourable outcome so that patient selection can be improved, but this needs further evaluation in larger patient cohorts. Orthotopic liver transplantation for patients with remission of disease or stable disease under medical treatment, and orthotopic liver transplantation for palliative reasons, should be restricted to selected individual cases.

Abstract
A multicenter retrospective review of 1467 patients treated by liver resection (LR) for hepatocellular carcinoma (HCC) in Europe over a 13-year period showed a mean mortality rate of 10.6%, which was correlated with the extent of LR, the etiology of cirrhosis and the study period with an improvement during the last years. Improved 5-year overall survival (20-51%) and disease-free survival (20-33%) reached similar rates in cirrhotic than in non-cirrhotic patients. Overall results were similar to those reported in Asian series as far as patients and tumor characteristics were comparable.

Abstract
The maximum extent of hepatic resection compatible with a safe postoperative outcome is unknown. The study goal was to determine the incidence and impact of a small remnant liver volume after major liver resection in patients with normal liver parenchyma. Among 265 major hepatectomies performed at our institution (1998 to 2000), 138 patients with normal liver and a remnant liver volume (RLV) systematically calculated from the ratio of RLV to functional liver volume (FLV) were studied. Patients were divided into five groups based on RLV-FLV ratio from </=30% to >/=60%. Kinetics of postoperative liver function tests were correlated with RLV. Postoperative complications were stratified by RLV-FLV ratios. Ninety patients (65%) underwent resection of up to four Couinaud segments. The RLV-FLV ratio was </=60% in 94 patients (68%) including only 13 (9%) with RLV-FLV </=30%. There was no linear correlation between the number of resected segments and the RLV-FLV. Postoperative serum bilirubin but not prothrombin time correlated with extent of resection. The incidence of complications including liver failure was not different among groups. Analysis of the four groups with a RLV-FLV ratio <60% showed a trend toward more complications and a longer intensive care unit stay in patients with the smallest RLVs. After major hepatectomy in patients with normal livers, the proportion of patients with a small remnant liver is low and not directly related to the number of segments resected. Although the rate of postoperative complications, including liver failure, did not directly correlate with the volume of remaining liver, the postoperative course was more difficult for patients with smaller remnants. Therefore preoperative portal vein embolization should be considered in patients who will undergo extended liver resection who have (1) injured liver or (2) normal liver when the planned procedure will be complex or when the anticipated RLV-FLV will be <30%.

Abstract
BACKGROUND The surgical strategy for treatment of synchronous colorectal liver metastases remains controversial. The outcome and overall survival of patients presenting with such metastases, treated either by simultaneous resection or by delayed resection, were evaluated. METHODS From 1987 to 2000, 97 patients presented with synchronous colorectal liver metastases, of whom 35 (36 per cent) underwent a simultaneous resection and 62 patients (64 per cent) a delayed resection. Simultaneous resection was considered prospectively for patients with fewer than four unilobar metastases. RESULTS Age, blood transfusion requirements, operating time, duration of inflow occlusion, hospital stay and mortality rate were similar in the two groups. The morbidity rate did not differ significantly (23 per cent after simultaneous resection and 32 per cent after delayed resection). The location of the primary tumour and extent of liver resection did not influence the morbidity rate significantly in the simultaneous resection group. The overall survival rate was 94, 45 and 21 per cent at 1, 3 and 5 years respectively after simultaneous resection, and 92, 45 and 22 per cent after delayed resection. CONCLUSION In selected patients, simultaneous resection of the colorectal primary tumour and liver metastases does not increase mortality or morbidity rates compared with delayed resection, even if a left colectomy and/or a major hepatectomy are required.

Abstract
BACKGROUND Hepatic metastases from neuroendocrine tumors have a protracted natural history and are associated with endocrinopathies. Resection is indicated for symptom control. Previous reports have suggested improvement in survival for patients undergoing debulking procedures. STUDY DESIGN The records of all consecutive patients undergoing resection of hepatic metastases from neuroendocrine tumors between 1977 and 1998 were reviewed. Tumors were classified according to histology, endocrine activity, and primary location. Patients lost to followup before 1 year were excluded. Followups were based on outpatient evaluations and were updated by correspondence. The Kaplan-Meier method was used to generate survival and recurrence curves, and the log-rank test was used for comparison. RESULTS A total of 170 patients fulfilled the inclusion criteria, of whom 73 were men. Mean age (+/-SD) was 57 (+/-11.5) years. Carcinoid (n = 120) and nonfunctioning islet cell tumors (n = 18) predominated; the ileum (n = 85) and the pancreas (n = 52) were the most common primary sites. Major hepatectomy (one or more lobes) was performed in 91 patients (54%). The postoperative complication rate was 14%, and two patients died (1.2%). Operation controlled symptoms in 104 of 108 patients, but the recurrence rate at 5 years was 59%. Operation decreased 5-hydroxyindoleacetic acid levels considerably, and no patient experienced carcinoid heart disease postoperatively. Recurrence rate was 84% at 5 years. Overall survival was 61% and 35% at 5 and 10 years, respectively, with no difference between carcinoid and islet cell tumors. CONCLUSIONS Hepatic resection for metastatic neuroendocrine tumors is safe and achieves symptom control in most patients. Debulking extends survival, although recurrence is expected. Hepatic resection is justified by its effects on survival and quality of life.
