Conventional Transarterial Chemo embolization Using Streptozocin in Patients with Unresectable Neuroendocrine Liver Metastases. Cancers (Basel) 2023; 15:4021. [PMID: 37627049 PMCID: PMC10452304 DOI: 10.3390/cancers15164021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 08/01/2023] [Accepted: 08/03/2023] [Indexed: 08/27/2023] Open
Abstract
BACKGROUND The purpose of this study was to evaluate the clinical, biological and radiological responses to, and tolerability of, conventional transarterial chemoembolization (cTACE) using streptozocin for unresectable neuroendocrine liver metastases. PATIENTS AND METHODS A total of 52 patients with predominant liver disease were treated with cTACE using an emulsion of streptozocin, Lipiodol and embolization particles. A sequential approach was favored in patients with high liver tumor burden. Clinical, biological and radiological responses were evaluated using carcinoid symptoms, biomarkers and mRecist criteria, respectively. RESULTS A total of 127 procedures were performed with a sequential approach in 65% of patients. All patients received streptozocin and Lipiodol. Carcinoid syndrome was improved in 69% of patients after treatment (p = 0.01). Post-embolization syndrome was reported in 78% of patients. At the end of all cTACE, objective response and non-progressive disease were 32% and 70%, respectively. Progression-free survival was 18.3 ± 13.3 months (median 14.9) and median overall survival (OS) from start of treatment was 74 months. The OS at 1 year, 2 years, 3 years and 5 years was 91% (IC = 84-99%), 84% (CI = 72-95%), 69% (CI = 53-84%) and 63% (C = 46-81%), respectively. CONCLUSIONS cTACE using streptozocin is an effective and well-tolerated palliative option for patients with neuroendocrine liver metastases, associated with prolonged survival and delayed time to progression.

Perioperative and long-term outcomes of laparoscopic liver resections for non-colorectal liver metastases. Surg Endosc 2019; 34:3833-3844. [PMID: 31586246 DOI: 10.1007/s00464-019-07148-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Accepted: 09/24/2019] [Indexed: 01/15/2023]
Abstract
BACKGROUND Liver is a common metastatic site not only of colorectal but of non-colorectal neoplasms, as well. However, resection of non-colorectal liver metastases (NCRLMs) remains controversial. The aim of this retrospective study was to analyze the short- and long-term outcomes of patients undergoing laparoscopic liver resection (LLR) for NCRLMs. METHODS From a prospectively maintained database between 2000 and 2018, patients undergoing LLR for colorectal liver metastases (CRLMs) and NCRLMs were selected. Clinicopathologic, operative, short- and long-term outcome data were collected, analyzed, and compared among patients with CRLMs and NCRLMs. RESULTS The primary tumor was colorectal in 354 (82.1%), neuroendocrine in 21 (4.9%), and non-colorectal, non-neuroendocrine in the remaining 56 (13%) patients. Major postoperative morbidities were 12.7%, 19%, and 3.6%, respectively (p = 0.001), whereas the mortality was 0.6% for patients with CRLMs and zero for patients with NCRLMs. The rate of R1 surgical margin was comparable (p = 0.432) among groups. According to the survival analysis, 3- and 5-year recurrence-free survival (RFS) rates were 76.1% and 64.3% in the CRLM group, 57.1% and 42.3% in the neuroendocrine liver metastase (NELM) group, 33% and 20.8% in the non-colorectal, non-neuroendocrine liver metastase (NCRNNELM) group (p = 0.001), respectively. Three- and 5-year overall survival (OS) rates were 88.3% and 82.7% in the CRLM group, 85.7% and 70.6% in the NELM group, 71.4% and 52.9% in the NCRNNELM group (p = 0.001), respectively. In total, 113 out of 354 (31.9%) patients with CRLMs, 2 out of 21(9.5%) with NELMs, and 8 out of 56 (14.3%) patients with NCRNNELMs underwent repeat LLR for recurrent metastatic tumors. CONCLUSION LLR is safe and feasible in the context of a multimodal management where an aggressive surgical approach, necessitating even complex procedures for bilobar multifocal metastases and repeat hepatectomy for recurrences, is the mainstay and may be of benefit in the long-term survival, in selected patients with NCRNNELMs.

Abstract
BACKGROUND Resection of liver metastasis in small bowel neuroendocrine tumors (SBNET) may improve survival, however, factors influencing prognosis are unclear. We evaluated how the extent of resection influences outcomes. METHODS Patients with SBNET with liver metastasis from 1990 to 2013 who underwent resection of the primary tumor were identified. Outcomes among patients undergoing complete resection (CR), partial resection (PR), or no resection (NR) of liver metastases with resection of the primary tumor only were compared. RESULTS One hundred eleven patients met the criteria. The median number of liver lesions was seven and median lesions resected was one. Fifty (45%) patients had NR, 41 (36.9%) underwent CR, and 20 (18.1%) underwent PR. The 5-year overall survival (OS) was 79.4% for NR, 84.7% for PR, and 100% for CR, demonstrating a trend that CR was best, followed by PR then NR (P = .02). 10-year OS showed no significant differences (72.7% NR; 84.7% PR; 82.5% CR; P = .10). Greater than 10 liver lesions (hazard ratio [HR] 3.6; P = 0.04) or receiving chemotherapy (HR 3.7; P = .03) were negative predictors of survival. CONCLUSION The extent of resection of liver disease in SBNET influenced survival at 5 years but not at 10 years. In addition, more than 10 liver lesions and chemotherapy were predictors of mortality.

Abstract
BACKGROUND The goals of resection of functional neuroendocrine tumors (NETs) are two-fold: Oncological benefit and symptom control. The interaction between the two is not well understood. METHODS All patients with functional NETs of the pancreas, duodenum, and ampulla who underwent curative-intent resection between 2000 and 2016 were identified. Using Cox regression analysis, factors associated with reduced recurrence-free survival (RFS) were identified. RESULTS Two-hundred and thirty patients underwent curative-intent resection. Fifty-three percent were insulinomas, 35% gastrinomas, and 12% were other types. Twenty-one percent had a known genetic syndrome, 23% had lymph node (LN) positivity, 80% underwent an R0 resection, and 14% had no postoperative symptom improvement (SI). Factors associated with reduced RFS included noninsulinoma histology, the presence of a known genetic syndrome, LN positivity, R1 margin, and lack of SI. On multivariable analysis, only the failure to achieve SI following resection was associated with reduced RFS. Considering only those patients with an R0 resection, failure to achieve SI was associated with worse 3-year RFS compared with patients having SI (36% vs 80%; P = 0.006). CONCLUSIONS Failure to achieve symptomatic improvement after resection of functional NETs is associated with worse RFS. These patients may benefit from short-interval surveillance imaging postoperatively to assess for earlier radiographical disease recurrence.

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
PURPOSE We aimed to evaluate the effectiveness and safety of radioembolization with yttrium-90 (90Y) microspheres in cases with unresectable neuroendocrine tumor liver metastases (NETLMs). METHODS Thirty patients (mean age, 55 years) underwent resin-based 90Y radioembolization for unresectable NETLM at a single institution between April 2008 and June 2013. Post-treatment tumor response was assessed by cross-sectional imaging using the Response Evaluation Criteria in Solid Tumors (RECIST). Prognostic variables that affected survival were determined. RESULTS The mean follow-up was 23.0±19.4 months and the median overall survival was 39 months (95% CI, 12.6-65.4 months), with one- and two-year survival rates of 71% and 45%, respectively. Imaging follow-up using RECIST at three-month intervals demonstrated partial response in 43%, complete remission in 3%, stable disease in 37%, and progressive disease in 17% of patients. Extent of tumor involvement was found to have a statistically significant influence on overall survival (P = 0.03). The existence of extrahepatic disease at the time of radioembolization, radiographic response, age, and primary neuroendocrine tumor site were not significant prognostic factors. CONCLUSION The current study demonstrates the effectiveness and safety of radioembolization for the treatment of unresectable NETLMs. We identified that the extent of tumor involvement has a significant effect on overall survival. The use of imaging methods reflecting metabolic activity or cellularity such as scintigraphy or diffusion-weighted MRI would be more appropriate, for the response evaluation of liver metastases after radioembolization.

Abstract
OBJECTIVE Yttrium-90 (Y-90) radioembolization is an emerging treatment option for unresectable neuroendocrine liver metastases (NELM). However, the data regarding this treatment are currently limited. This study evaluates the efficacy and tolerability of Y-90 radioembolization and identifies prognostic factors for radiographic response and survival. METHODS AND MATERIALS Thirty-eight patients underwent Y-90 radioembolization for NELM at our institution between April 2004 and February 2012. Patients were assessed radiographically (RECIST criteria, enhancement), serologically, and clinically at 1month, and then at every 3months after treatment for tumor response, toxicity, and survival outcomes. RESULTS Median length of follow-up was 17.0months (IQR, 9.0-37.0). Median survival was 29.2months. Three patients (9%) had a radiographic complete response to treatment, 6 (17%) had a partial response, 21 (60%) had stable disease, and 5 (14%) developed progressive disease. Two factors were significantly associated with a good radiographic response (complete/partial response): islet cell histological subtype (p=0.043) and hepatic tumor burden ≥33% (p=0.031). Multivariate analysis revealed that patients requiring multiple Y-90 treatments (HR 2.9, p=0.035) and patients who had previously failed systemic therapy with octreotide/chemotherapy (HR 4.4, p=0.012) had worse survival. Grade 3 serologic toxicity was observed in 2 patients (5%; hyperbilirubinemia, elevated alkaline phosphatase) after treatment. Grade 3 non-serologic toxicities included abdominal pain (11%), fatigue (11%), nausea/vomiting (5%), ascites (5%), dyspnea (3%), diarrhea (3%), and peripheral edema (3%). No grade 4 or 5 toxicity was reported. CONCLUSIONS Y-90 radioembolization is a promising treatment option for inoperable NELM and is associated with low rates of grade≥3 toxicity.

Abstract
Pancreatic neuroendocrine tumors (PNETs) are neoplasms that arise from the hormone producing cells of the islets of Langerhans, also known as pancreatic islet cells. PNETs are considered a subgroup of neuroendocrine tumors, and have unique biology, natural history and clinical management. These tumors are classified as 'functional' or 'non-functional' depending on whether they release peptide hormones that produce specific hormone- related symptoms, usually in established patterns based on tumor subtype. This manuscript will review pancreatic neuroendocrine tumor subtypes, syndromes, diagnosis, and clinical management.

Abstract
BACKGROUND Neuroendocrine tumors (NETs) metastatic to the liver are treated with transarterial radioembolization (TARE) using yttrium-90 (Y-90) microspheres or transarterial chemoembolization (TACE). However the criteria for patient selection are not well defined. We sought to determine if Ki67 score could help select patients for one therapy over the other in the management of hepatic neuroendocrine metastases. METHODS Single institution analysis of patients treated with Y-90 or TACE between 2001 and 2014. Pathologists blinded to clinical information performed Ki67 staining. Data were analyzed using multivariate association for survival outcomes. RESULTS Amongst 72 patients (male: 39, female: 33, median age: 57 years) with metastatic NET, the most common site of origin was small bowel (n=35, 49%), while pancreas constituted 32% (n=23). Forty-four patients were treated with Y-90 (61%) and 28 patients received TACE (39%). Ki67 score was available in 28 patients (64%) treated with Y-90 and 16 patients (57%) with TACE. Within Y-90 group, there was greater use of Sandostatin (95% vs. 75%, P=0.02) and less number of total treatments completed (89% vs. 46%, P<0.001). There was no significant difference in overall survival (OS) between Y-90 and TACE when used without selection (median, 69 vs. 82 months, P=0.47). When adjusted for Ki67, patients with Ki67 score ≥3% had better OS with Y-90 compared to TACE (HR, 0.1; CI, 0.01-0.9), however for Ki67 <3%, OS was better when treated with TACE compared to Y-90 (HR, 13.5; CI, 1.22-148.87). CONCLUSIONS There is significant interaction between Ki-67 score and liver-directed treatment benefit in patients with hepatic neuroendocrine metastases. Ki-67 score ≥3% predicts greater benefit with Y-90 and a Ki-67 score <3% predicts greater benefit with TACE.

Abstract
The continuing controversy about surgery for non-colorectal non-neuroendocrine liver metastases (NCRNNE) necessitates identifying risk factors of worsened outcomes to improve patient selection and survival. Prospectively collected data of 167 patients undergoing hepatectomy for NCRNNE were analyzed, and a comparison to a matched population of colorectal liver metastases (CLM) was performed. Overall survival (OS) (35 vs. 54 months; P = 0.008) and recurrence-free survival (RFS) (15 vs. 29 months; P = 0.004) of NCRNNE patients were significantly shorter compared to those with CLM. The best survival was found in the genitourinary (GU; OS, 45 months; RFS, 21 months) NCRNNE subgroup, whereas survival for gastrointestinal (GI) metastases was low (OS, 8 months; RFS, 7 months). Patients with renal cell carcinoma (RCC) showed excellent outcomes when compared to CLM (OS, 50 vs. 51 months; P = 0.901). Extrahepatic disease (EHD) was identified as independent prognostic factor for reducing both RFS (P = 0.040) and OS (P = 0.046). The number of liver lesions (P = 0.024), residual tumor (P = 0.025), and major complications (P = 0.048) independently diminished OS. The degree of survival advantage by surgery is determined by the primary tumor site, EHD, the number of metastases, and residual tumor. Thus-even more than in CLM-these oncological selection criteria must prevail. GU metastases, especially RCC, represent a favorable subgroup.

Abstract
PURPOSE Gastro-entero-pancreatic neuroendocrine tumors (GEPNETs) are increasing in incidence, and accurate staging is important for selecting the appropriate treatment. (68)Ga-DOTATATE imaging is a promising approach for detecting GEPNETs and could help in selecting optimal therapeutic strategies. The aim of this study was to prospectively determine the clinical utility of (68)Ga-DOTATATE positron emission tomography (PET)/computed tomography (CT) in detecting unknown primary and metastatic GEPNETs. PATIENTS AND METHODS One hundred thirty-one patients were enrolled in a prospective study of patients undergoing (68)Ga-DOTATATE PET/CT, (111)In-pentetreotide single-photon emission computed tomography (SPECT)/CT and multiphasic CT scan, and/or magnetic resonance imaging in a blinded fashion with comprehensive biochemical testing. The primary outcome measure was the detection of lesions by each imaging study. RESULTS (68)Ga-DOTATATE PET/CT imaging detected 95.1% of lesions (95% CI, 92.4% to 96.8%) with an average maximum standardized uptake value of 65.4 ± 47 (range, 6.9 to 244), anatomic imaging detected 45.3% of lesions (95% CI, 37.9% to 52.9%), and (111)In-pentetreotide SPECT/CT detected 30.9% of lesions (95% CI, 25.0% to 37.5%), with a significant difference between imaging modalities (P < .001). In four of 14 patients (28.6%), (68)Ga-DOTATATE PET/CT found a previously unknown primary tumor, and detected primary GEPNET, lymph node, and distant metastases correctly in 72 of 113 lesions (63.7%) when compared with histopathology, with 22.1% and 38.9% detected by using (111)In-pentetreotide SPECT/CT and anatomic imaging, respectively. On the basis of findings with (68)Ga-DOTATATE PET/CT, 43 of 131 patients (32.8%) had a change in management recommendation. In patients with carcinoid symptoms but negative biochemical testing, (68)Ga-DOTATATE PET/CT detected lesions in 65.2% of patients, 40% of which were detected neither by anatomic imaging nor by (111)In-pentetreotide SPECT/CT. CONCLUSION (68)Ga-DOTATATE PET/CT imaging provides important information for accurate staging of GEPNETs and selection of appropriate treatment interventions even in the absence of biochemical evidence of disease in symptomatic patients.

Abstract
Neuroendocrine tumors (NETs) of the gastrointestinal (GI) tract have a propensity for producing hepatic metastases. Most GI NETs arise from the foregut or midgut, are malignant, and can cause severe debilitating symptoms adversely affecting quality of life. Aggressive treatments to reduce symptoms have an important role in therapy. Patients with GI NETs usually present with inoperable metastatic disease and severe symptoms from a variety of hormones and biogenic amines. This article describes intra-arterial hepatic-directed therapies for metastases from NETs, a group of treatments in which the therapeutic and/or embolic agents are released intra-arterially in specific hepatic vessels to target tumors.

Abstract
BACKGROUND Patient selection for liver transplantation for metastatic neuroendocrine tumors remains a topic of debate. There is no established MELD exception, making it difficult to obtain donor organs. METHODS A multicenter database was created assessing outcomes for liver and multivisceral transplantation for metastatic neuroendocrine tumors and identifying prognostic factors for survival. Demographic, transplant, primary tumor site and management, pathology, recurrent disease and survival data were collected and analyzed. Survival probabilities were calculated using the Kaplan-Meier method. RESULTS Analysis included 85 patients who underwent liver transplantation November 1988-January 2012 at 28 centers. One, three, and five-year patient survival rates were 83%, 60%, and 52%, respectively; 40 of 85 patients died, with 20 of 40 deaths due to recurrent disease. In univariate analyses, the following were predictors of poor prognosis: large vessel invasion (P < 0.001), extent of extrahepatic resection at liver transplant (P = 0.007), and tumor differentiation (P = 0.003). In multivariable analysis, predictors of poor overall survival included large vessel invasion (P = 0.001), and extent of extrahepatic resection at liver transplant (P = 0.015). CONCLUSION In the absence of poor prognostic factors, metastatic neuroendocrine tumor is an acceptable indication for liver transplantation. Identification of favorable prognostic factors should allow assignment of a MELD exception similar to hepatocellular carcinoma.

BMJ Open 2015; 5:e008248.

Abstract
INTRODUCTION Finding the optimal management strategy for patients with advanced, metastatic neuroendocrine tumours (NETs) of the gastrointestinal tract and pancreas is a work in progress. Sunitinib and everolimus are currently approved for the treatment of progressive, unresectable, locally advanced or metastatic low-grade or intermediate-grade pancreatic NETs. However, mutation-targeted therapy with sunitinib or everolimus has not been studied in this patient population. METHODS AND ANALYSIS This prospective, open-label phase II clinical trial was designed to determine if mutation-targeting therapy with sunitinib or everolimus for patients with advanced low-grade or intermediate-grade NETs is more effective than historically expected results with progression-free survival (PFS) as the primary end point. Patients ≥18 years of age with progressive, low-grade or intermediate-grade locally advanced or metastatic NETs are eligible for this study. Patients will undergo tumour biopsy (if they are not a surgical candidate) for tumour genotyping. Patients will be assigned to sunitininb or everolimus based on somatic/germline mutations profile. Patients who have disease progression on either sunitinib or everolimus will crossover to the other drug. Treatment will continue until disease progression, unacceptable toxicity, or consent to withdrawal. Using the proposed criteria, 44 patients will be accrued within each treatment group during a 48-month period (a total of 88 patients for the 2 treatments), and followed for up to an additional 12 months (a total of 60 months from entry of the first patient) to achieve 80% power in order to test whether there is an improvement in PFS compared to historically expected results, with a 0.10 α level one-sided significance test. ETHICS AND DISSEMINATION The study protocol was approved by the institutional review board of the National Cancer Institute (NCI-IRB Number 15C0040; iRIS Reference Number 339636). The results will be published in a peer-reviewed journal and shared with the worldwide medical community. TRIAL REGISTRATION NUMBER NCT02315625.

Abstract
Background The role of liver resection for non-colorectal, non-neuroendocrine, non-sarcoma (NCNNNS) metastases is ill-defined. This study aimed to examine the oncologic outcomes of liver resection in such patients. Methods A retrospective analysis of liver resection for NCNNNS metastases was performed at two large centers. Liver resection was offered selectively in patients with stable disease. Oncologic outcomes were examined using the Kaplan-Meier method. Results Fifty-two patients underwent liver resection for NCNNNS metastases. Overall 5-year survival was 58%. Five-year survival was 85% for breast metastases, 66% for ocular melanoma, 83% for other melanomas, 50% for gastro-esophageal metastases, and 0% for renal cell carcinoma metastases. A contemporary colorectal liver metastasis cohort had a survival of 63% (p=0.89). Conclusions Liver resection is an effective option in the management of selected patients with NCNNNS metastases which have been deemed stable. Five-year survival rates were comparable to that of a contemporary cohort of patients with colorectal liver metastases in carefully selected patients. Further, larger studies are required to help identify potential prognostic variables and aid in decision-making in this heterogeneous population.

Abstract
Abstract: Neuroendocrine tumors (NETs) commonly metastasize to the liver. Different treatments are available for the management of metastatic NETs. Both primary tumor and metastases can significantly affect the patients’ quality of life and overall survival (OS). Surgical resection is the only chance for cure and should be considered for every patient. For operable patients, current evidence suggests that liver resection is a safe and effective treatment for neuroendocrine liver metastases. High rates of recurrence are reported following resection of neuroendocrine liver metastases. There is no evidence to support incomplete (R2) resection (debulking) surgery to improve OS or quality of life. When surgery is performed for NETs, other conservative adjuvant treatments should also be considered to prolong symptom-free, disease-free and OS.

Abstract
Purpose Management of gastroenteropancreatic (GEP) neuroendocrine tumors with liver metastases (NETLM) presents many clinical challenges. Assessment of the extent of disease and primary tumor site is crucial for management. In this study, we investigated the primary tumor sites and prognostic factors in GEP NETLM among Korean patients. Materials and Methods We reviewed the medical records of 72 Korean patients diagnosed with GEP NETLM between January 1999 and May 2013, focusing on their clinical and pathologic characteristics. Results The most frequently encountered primary tumor sites were the pancreas (n=25, 35%), stomach (n=8, 11%), gall bladder (n=4, 6%) and rectum (n=3, 4%). Twenty-five patients (35%) had occult primary tumor. Twelve patients (17%) had histological grade G1 tumors, 30 patients (42%) had G2 tumors, and 30 patients (42%) had G3 tumors. The mean follow-up period after histological confirmation of hepatic metastases was 11.30±2.44 months for G3 tumors, 19.67±4.09 months for G2 tumors, and 30.67±6.51 months for G1 tumors. Multivariate analyses revealed that an unknown primary tumor site (p=0.001) and higher histological grade (p < 0.001) were independent prognostic indicators for shorter overall survival (OS). Most long-term survivors (OS > 24 months) had received antitumor treatment. Conclusion The primary tumor site most frequently associated with GEP NETLM was the pancreas. Unknown primary tumor and higher histological grade were independent prognostic indicators for shorter OS. Patients identified as being at a risk of shorter OS should be followed up closely.

Abstract
The aim of the study was to analyze the safety and efficacy of yttrium-90 ((90)Y) radioembolization in the treatment of unresectable hepatic melanoma metastases refractory to previous systemic/locoregional therapy. Between February 2004 and April 2010, 16 patients with hepatic melanoma metastases (ocular=7, skin=4, other sites=5) were treated with (90)Y radioembolization at a single center. Toxicity was assessed using the National Cancer Institute Common Terminology Criteria, version 3.0. Response to therapy was assessed by size and necrosis criteria. Progression-free survival (hepatic) and overall survival were calculated using the Kaplan-Meier method. The median dose to the treatment site was 108.57 Gy. Grade 1 and 2 clinical toxicities included fatigue (44%), nausea (19%), and vomiting (12%). Grade 3 absolute lymphocyte toxicity and aspartate aminotransferase toxicity were noted in 2 (12%) and 1 (7%) patients, respectively. Grade 4 bilirubin toxicity was observed in 1 (7%) patient. Overall, 13 (81%) patients showed disease control (response+stable disease) according to WHO, European Association for the Study of the Liver, and Response Evaluation Criteria for Solid Tumors. Progressive disease was observed in 3 (19%) patients according to WHO, European Association for the Study of the Liver, and Response Evaluation Criteria for Solid Tumors. The median overall and hepatic progression-free survival times were 7.63 and 4.23 months. Patients with disease control (responders+stable disease) survived longer than those with progressive disease (9.97 vs. 2.13 months, P<0.0001). Results from this small and single-center experience show that radioembolization is a safe therapy and its potential for being an efficacious therapy for hepatic melanoma metastases should be explored further. Radioembolization should be considered for liver-dominant disease refractory to other forms of systemic therapies.

METHODS This study included 161 patients with surgically confirmed pancreatic neuroendocrine neoplasms. Pathology slides were reviewed to determine the tumour grade. CT image analysis included size, pattern, calcification, margin, pancreatic duct dilatation, bile duct dilatation, vascular invasion, arterial enhancement ratio, and portal enhancement ratio. We used 2 cm, 3 cm, and 4 cm as cutoff values of tumour size and 0.9 and 1.1 of enhancement ratio to determine the sensitivity and specificity. RESULTS Pathology analysis identified 167 lesions in 161 patients. 154 lesions (92 %) were grade 1/2 and 13 (8 %) were grade 3. Portal enhancement ratio (< 1.1) showed high sensitivity and specificity 92.3 % and 80.5 %, respectively in differentiating grade 3 from grade 1/2. It showed the highest odds ratio (49.60), followed by poorly defined margin, size (> 3 cm), bile duct dilatation, and vascular invasion. When at least two of these five criteria were used in combination, the sensitivity and specificity for diagnosing grade 3 were 92.3 % (12/13) and 87.7 % (135/154), respectively. CONCLUSIONS By using specific CT findings, grade 3 can be differentiated from grade 1/2 with a high diagnostic accuracy leading to an appropriate imaging staging. KEY POINTS • Neuroendocrine carcinomas should be differentiated from neuroendocrine tumours. • Neuroendocrine carcinomas can be differentiated from neuroendocrine tumours on dynamic CT. • Neuroendocrine carcinomas show iso- or hypo-enhancement on portal venous phase CT.

Abstract
The ideal management of NET must be addressed on a case-by-case basis, with consideration given to patient factors, disease burden, and clinical tumor activity. Outcome improvement for LT in the setting of metastatic disease requires better characterization of the biological behavior of NETs and further identification of factors to be included in the selection criteria. Box 3 summarizes the many areas that have been, and are currently, undergoing investigation. LT as an attempt for cure rather than palliation is a justified treatment option for well-selected patients with metastatic neuroendocrine tumors of the pancreas and GI system. Optimization of pretransplantation staging and patient management algorithms, patient selection, and posttransplant management options are areas that need to be better defined. Further investigations for defining reproducible prognostic factors, consistent histopathologic evaluation, and uniform preoperative staging and site-specific data are needed. With the advancement of newer treatment modalities, it is necessary to define the role of LT along with the optimal perioperative management of existing and recurrent disease.

Abstract
Neuroendocrine tumors (NET) are a heterogeneous group of cancers, with indolent behavior. The most common primary origin is the gastro-intestinal tract but can also appear in the lungs, kidneys, adrenals, ovaries and other organs. In general, NET is usually discovered in the metastatic phase (40%-80%). The liver is the most common organ involved when metastases occur (40%-93%), followed by bone (12%-20%) and lung (8%-10%).A number of different therapeutic options are available for the treatment of hepatic metastases including surgical resection, transplantation, ablation, trans-arterial chemoembolization, chemotherapy and somatostatin analogues. Recently, molecular targeted therapies have been used, usually in combination with other treatment options, to improve outcomes in patients with metastases. This article emphasizes on the role of surgery in the treatment of liver metastases from NET.

Abstract
PURPOSE Whereas resection of colorectal liver metastases is gold standard, there is an ongoing debate on benefit of resection of non-colorectal (NCRC) and non-neuroendocrine (NNEC) liver metastases. METHODS The potential survival benefit of patients undergoing resection of NCRC or NNEC liver metastases was investigated. Data from a prospectively maintained database were reviewed over a 7-year period. Kaplan-Meier method was used for the evaluation of outcome following resection. RESULTS 101 patients underwent 116 surgical procedures for synchronous and metachronous NCRC or NNEC liver metastases with a morbidity of 23% and a mortality of ∼1%. 11 patients underwent repeated liver resection procedures. Overall 5-year survival after liver resection was 30% depending on primary tumour site. Median survival was significantly increased after resection of hepatic metastases from non-gastrointestinal primaries compared to gastrointestinal primaries. Resection of hepatic metastases from non-gastrointestinal primaries resulted in significantly increased median survival compared to exploration only. Patients with hepatic metastases from gastrointestinal primaries did not benefit from hepatic surgery. CONCLUSION Hepatic resection for liver metastases from NCRC or NNEC cancers is a save treatment procedure. However, the decision to perform surgery should depend on the primary cancer. Especially patients with liver metastases from non-gastrointestinal primaries profit from hepatic surgery.

Abstract
Neuroendocrine tumors, particularly those of gastrointestinal tract origin, have a predisposition for metastasizing to the liver, causing parenchymal substitution and paraneoplastic syndrome. Lipiodol embolization combined with anticancer drugs is a recent tool in regional therapy. It has been proven that chemoembolization reduces tumor bulk and hormone levels, and that it palliates the symptoms of many patients with liver-dominant neuroendocrine metastases. Beginning in December 1988, ten patients with unresectable and chemotherapy-refractory liver metastatic neuroendocrine tumors were treated with chemoembolization based on a mixture of lipiodol, mitomycin, cisplatin, epirubicin, followed by gelfoam powder and contrast media. Toxicity encountered included: upper right quadrant pain requiring narcotics, elevation of lactate dehydrogenase, alkaline phosphatase, and transaminases. One patient had liver abscess and persistent fever for 2 weeks. We obtained two complete remissions lasting 12 and 34 months and 5 partial remissions. The median survival was 22 months. Four patients had urinary elevation of 5-hydroxyindolacetic acid (5-HIAA). They showed more than a 75% decrease in urinary secretion after treatment. In a patient with transplanted liver we noticed a partial response lasting 7 months. We conclude that chemoembolization will improve the clinical condition of a significant percentage of patients with liver metastases, that future therapy of carcinoid tumors will be based on specific tumor biology and that treatment will be customized for each individual patient combining the use of cytoreductive procedures including radiofrequency ablation, laser treatment and chemoembolization.

Abstract
OBJECTIVE The purpose of this study was to assess outcomes and indications in a large cohort of patients who underwent liver transplantation (LT) for liver metastases (LM) from neuroendocrine tumors (NET) over a 27-year period. BACKGROUND LT for NET remains controversial due to the absence of clear selection criteria and the scarcity and heterogeneity of reported cases. METHODS This retrospective multicentric study included 213 patients who underwent LT for NET performed in 35 centers in 11 European countries between 1982 and 2009. One hundred seven patients underwent transplantation before 2000 and 106 after 2000. Mean age at the time of LT was 46 years. Half of the patients presented hormone secretion and 55% had hepatomegaly. Before LT, 83% of patients had undergone surgical treatment of the primary tumor and/or LM and 76% had received chemotherapy. The median interval between diagnosis of LM and LT was 25 months (range, 1-149 months). In addition to LT, 24 patients underwent major resection procedures and 30 patients underwent minor resection procedures. RESULTS Three-month postoperative mortality was 10%. At 5 years after LT, overall survival (OS) was 52% and disease-free survival was 30%. At 5 years from diagnosis of LM, OS was 73%. Multivariate analysis identified 3 predictors of poor outcome, that is, major resection in addition to LT, poor tumor differentiation, and hepatomegaly. Since 2000, 5-year OS has increased to 59% in relation with fewer patients presenting poor prognostic factors. Multivariate analysis of the 106 cases treated since 2000 identified the following predictors of poor outcome: hepatomegaly, age more than 45 years, and any amount of resection concurrent with LT. CONCLUSIONS LT is an effective treatment of unresectable LM from NET. Patient selection based on the aforementioned predictors can achieve a 5-year OS between 60% and 80%. However, use of overly restrictive criteria may deny LT to some patients who could benefit. Optimal timing for LT in patients with stable versus progressive disease remains unclear.

Abstract
BACKGROUND Although controversial, surgical resection for metastatic carcinoid tumors (MCTs) can potentially prolong survival. METHODS Patients with MCTs were identified from the Surveillance, Epidemiology and End Results database. Patients undergoing surgery were compared to unresected patients. RESULTS Surgery was performed in 33% of patients. Predictors of surgery included age <50 years (odds ratio [OR], 2.4), low grade (OR, 3.1), and the appendix (OR, 36.2) or small intestine (OR, 27.2) as the primary site. Predictors of adverse survival included high grade (hazard ratio, 2.4) and no surgery (hazard ratio, 2.5) or surgery on only primary or distant disease (hazard ratio, 1.5) compared with surgery for both. Survival at 5 years was 5% with no surgery, 28% with surgery on either site, and 46% with surgery at both sites (P < .001). CONCLUSIONS Surgery for MCTs is more common in younger patients, those with low-grade disease, and those with small bowel or appendiceal primary tumors. Although selection bias cannot be excluded, these data lend support to "debulking" for MCT.

Abstract
Introduction. The role of hepatic resection in patients with liver metastases from gastroenteropancreatic neuroendocrine tumors (GEP-NETs) is still poorly defined. Therefore, we examined the results obtained with surgical resection and other locoregional or systemic therapies by reviewing the recent literature on this topic. We performed the meta-analysis for comparing surgical resection of hepatic metastases with other treatments. Materials and Methods. In this systematic review and meta-analysis of observational studies, the literature search was undertaken between 1990 and 2012 looking for studies evaluating the different survivals between patients treated with surgical resection of hepatic metastases and with other surgical or nonsurgical therapies. The studies were evaluated for quality, publication bias, and heterogeneity. Pooled hazard ratio (HR) estimates and 95% confidence intervals (CI.95) were calculated using fixed-effects model. Results. We selected six studies in the review, five of which were suitable for meta-analysis. We found a significant longer survival in patients treated with hepatic resection than embolisation HR 0.34 (CI.95 0.21-0.55) or all other nonsurgical treatments HR 0.45 (CI.95 0.34-0.60). Only one study compared surgical resection with liver transplantation and meta-analysis was not feasible. Conclusions. Our meta-analysis provides evidence supporting the hypothesis that hepatic resection increases overall survival in patients with liver metastases from GEP-NETs. Further randomized clinical trials are needed to confirm these findings and it would be desirable to identify new markers to properly select patients for surgical treatment.

Abstract
BACKGROUND Surgical extirpation of neuroendocrine neoplasms hepatic metastases (NENHM) provides the best opportunity of long-term survival but is not feasible in the majority of patients given the widespread presentation of liver disease. Combining resection with local ablation can potentially expand the resection criteria and thereby improve survival. The present study critically evaluates the progression-free survival (PFS) and overall survival (OS) of patients with NENHM who underwent concomitant hepatic resection and cryoablation. METHODS Forty patients with NENHM underwent concomitant hepatic resection and cryoablation between December 1992 and June 2010. PFS and OS were determined; clinicopathologic and treatment-related factors associated with PFS and OS were evaluated through univariate and multivariate analyses. RESULTS The median follow-up for the patients who were alive was 61 months (range, 1 to 162 mo). The median PFS and OS after hepatic resection were 22 and 95 months, respectively. Five-year and 10-year OS rate was 61% and 40%, respectively. One independent factor was associated with OS: histologic grade (P=0.001). One independent factor was associated with PFS: extrahepatic disease (P=0.003). CONCLUSION Concomitant hepatic resection and cryoablation to achieve tumor debulking is associated with excellent survival outcomes in selected patients. This approach may increase the number of patients with borderline resectable disease undergoing surgical management of advanced NENHM.

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
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
The incidence of gastrointestinal carcinoids appears to be increasing, and the rectum is the third most common location. Transcatheter arterial embolization (TAE) with trisacryl gelatin microspheres (Embosphere®) has been reported as an effective method for hepatic metastases of rectal carcinoids. Complications are uncommon and usually of minor consequence. We report an unusual case of a 34-year-old man with tumor lysis syndrome following TAE with Embosphere® in a patient with multiple hepatic metastases of a rectal carcinoid. Early detection and effective treatment are essential for this rare but potentially catastrophic complication.

Abstract
BACKGROUND Surgery confers the best chance of long-term survival in patients with neuroendocrine neoplasm hepatic metastases (NENHM). Disease progression invariably occurs in the majority of patients. No previous study has addressed the outcomes after treatment of hepatic disease progression in patients who initially underwent surgical extirpation of NENHM. This was the principal aim of the current study. METHODS Seventy-four patients with NENHM underwent surgery for NENHM between December 1992 and December 2009. Of these, 50 patients developed disease progression in the liver. These patients were then treated with specific liver-directed therapies according to consensus of a multidisciplinary team. The current study evaluates progression-free survival (PFS) and overall survival (OS) following treatment of hepatic disease progression with specific liver-directed therapies. RESULTS No patient was lost to follow up. The median follow-up after treatment of progression was 29 months (range = 2-137). The median PFS and OS after diagnosis of disease progression were 15 and 48 months, respectively. Specific liver-directed therapies included surgery in 10 patients, radioembolization in 15, cytotoxic chemotherapy in 14, and conservative therapy in 11. Four independent factors associated with PFS and OS were identified through a multivariate analysis. These were initial progression-free survival (PFS, P = 0.006, HR= 0.32), extra-hepatic disease (OS, P = 0.029, HR = 4.04; PFS, P = 0.004, HR = 4.03), histological grade (PFS, P = 0.006, HR = 4.08), and type of secondary intervention (PFS, P = 0.024, HR = 0.63). CONCLUSION A multimodality approach towards treatment of disease progression as shown in this study that includes repeat surgery or radioembolization has been shown to achieve a superior outcome in the setting of disease progression/recurrence.

Abstract
Primary neuroendocrine carcinoma of the hypopharynx is extremely rare. A 59-year-old man complaining of swollen right cervical lymph node was admitted to our hospital. Although computed tomography, upper endoscopy, and positron emission tomography scan were performed, the primary lesion was unknown. Bilateral neck lymph node dissection was performed and diagnosed as metastasis of neuroendocrine carcinoma. Sixteen months after the first operation, computed tomography scan revealed multiple liver metastases. There was no another metastatic lesion, and hepatectomy with negative margin was performed. Three months after the second operation, a small tumor of the hypopharynx was detected by upper endoscopy, and biopsy revealed neuroendocrine carcinoma. Concurrent chemotherapy (cisplatin + docetaxel) and radiotherapy (60 Gy) were carried out. This therapy was highly effective, and primary lesion disappeared. After the chemoradiotherapy, lung metastasis and bone metastasis emerged and treated by radiotherapy and chemotherapy (cisplatin + irinotecan). These therapies were also effective, but multiple liver metastases appeared. The patient died 39 months after the first surgery. Although neuroendocrine carcinoma is a high-grade malignancy which metastasizes easily, combined treatment strategy may be useful for these patients. We have here reported, with bibliographic consideration, a case in which multimodal treatment was employed for primary hypopharyngeal neuroendocrine carcinoma with distant metastases.

Abstract
BACKGROUND The aim of the present study was to analyse the outcome after hepatic resection for non-colorectal, non-neuroendocrine, non-sarcomatous (NCNNNS) metastatic tumours and to identify the factors predicting survival. METHODS All patients who underwent hepatic resection for NCNNNS metastatic tumours between September 1996 and June 2009 were included. Patients' demographics, clinical and histopathological parameters, overall survival and the factors predicting survival were analysed. RESULTS In all, 65 patients underwent hepatic resection for metastasis. The most common site of a primary tumour was the kidney (24 patients). Fifteen patients had synchronous tumours. Fifty patients had major liver resections and 22 patients had bilobar disease. The median number of liver lesions resected was 1 and the median maximum diameter of the metastasis was 6 cm. A R0 resection was performed in 51 patients. The 1-, 3- and 5-year overall survival from the time of metastasectomy was 72.9%, 47.9% and 25.6%, respectively, with a median survival of 19 months. The presence of a tumour of greater than 6 cm (P= 0.048) and a positive resection margin (P= 0.04) were associated with poor survival. CONCLUSION Hepatic resection for metastasis from NCNNNS tumours can offer acceptable long-term survival in selected patients. To offer a chance of a cure a R0 resection must be performed.

Dong XD, Carr BI. Hepatic artery chemoembolization for the treatment of liver metastases from neuroendocrine tumors: a long-term follow-up in 123 patients. Med Oncol 2010; 28 Suppl 1:S286-90. [PMID: 21107755 DOI: 10.1007/s12032-010-9750-6] [Citation(s) in RCA: 41] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2010] [Accepted: 11/12/2010] [Indexed: 12/14/2022]
Abstract
Neuroendocrine tumors (NETs) of the gastrointestinal tract have a propensity for hepatic metastases. Surgical resection for hepatic metastases remains the gold standard for long-term survival, but many patients present with multifocal tumors, precluding surgery with increasing use of chemoembolization. However, there are few studies examining long-term survival factors. We reviewed our 15-year experience with chemoembolization in 123 patients with unresectable NET liver metastases, whose prognosis was evaluated upon baseline clinical factors. There were 64 males (53%) and 59 females (47%). Average age at presentation was 56 years (range: 14.3-85.5 years). Abdominal pain (44%) was the most common presenting symptom, followed by diarrhea (30%) and weight lost (22%). Patients underwent an average 7.3 cycles of chemoembolization (range 1-32 cycles). Responses: 62% of patients had PR; 24% had stable disease and 14% had tumor progression. Overall 3-, 5- and 10-year survivals were 59, 36 and 20% of patients with a mean follow-up of 3.2 years (range 2 weeks-18.3 years) and mean survival of 3.3 years. Univariate analysis showed that age greater than 60 years had worse outcome (P < 0.01), as did baseline serum albumin of ≤ 3.5 g/dL and prothrombin time >13 s. Location of the primary tumor (P = 0.68), gender (P = 0.4) and serum NET peptide levels did not influence survival. However, multivariate analysis showed that a low baseline serum albumin level was an independent factor for prognosis (P = 0.003). Chemoembolization for unresectable NETs metastatic to liver is useful for tumor size reduction, symptom palliation and can be associated with prolonged survival.

Abstract
The optimal treatment of patients with gastroenteropancreatic neuroendocrine tumors requires accurate staging. Nuclear medicine is an imaging technique that provides functional information. In gastroenteropancreatic neuroendocrine tumors this information is obtained from radiotracers providing data on amine synthesis (MIBG) and/or somatostatin receptor expression (111-In-octreotide, 68Galio-DOTATOC) by the tumoral cell, both in primary and metastatic tumors. The accumulated experience shows that nuclear medicine techniques are essential in the management of these patients. The indications in the diagnosis, extension study and follow-up of these tumors, as well as the distinct radiotracers available, are reviewed.

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
Orthotopic liver transplantation (OLT) is currently incorporated into the treatment regimens for specific nonhepatocellular malignancies. For patients suffering from early-stage, unresectable hilar cholangiocarcinoma (CCA), OLT preceded by neoadjuvant radiotherapy has the potential to readily achieve a tumor-free margin, accomplish a radical resection, and treat underlying primary sclerosing cholangitis when present. In highly selected stage I and II patients with CCA, the 5-year survival rate is 80%. As additional data are accrued, OLT with neoadjuvant chemoradiation may become a viable alternative to resection for patients with localized, node-negative hilar CCA. Hepatic involvement from neuroendocrine tumors can be treated with OLT when metastases are unresectable or for palliation of medically uncontrollable symptoms. Five-year survival rates as high as 90% have been reported, and the Ki67 labeling index can be used to predict outcomes after OLT. Hepatic epithelioid hemangioendothelioma is a rare tumor of vascular origin. The data from single-institution series are limited, but compiled reviews have reported 1- and 10-year survival rates of 96% and 72%, respectively. Hepatoblastoma is the most common primary hepatic malignancy in children. There exist subtle differences in the timing of chemotherapy between US and European centers; however, the long-term survival rate after transplantation ranges from 66% to 77%. Fibrolamellar hepatocellular carcinoma is a distinct liver malignancy best treated by surgical resection. However, there is an increasing amount of data supporting OLT when resection is contraindicated. In the treatment of either primary or metastatic hepatic sarcomas, unacceptable survival and recurrence rates currently prohibit the use of OLT.

Abstract
This review summarizes regional strategies for management of neuroendocrine liver metastases (NLM), including hepatic resection, ablation, liver transplantation, and hepatic arterial embolization/chemoembolization. Despite early disease recurrence and/or progression, resection of NLM with or without combined ablation provides long-term survival and symptom improvement. When complete resection of gross liver disease is not feasible, resection as a tumor debulking strategy should be considered in patients with extreme hormonal symptoms refractory to other treatments or with tumors in locations that would affect short-term quality of life. Hepatic arterial embolization with or without local instillation of chemotherapy may induce disease response, symptomatic improvement, and prolonged survival in patients with unresectable NLM. Early disease recurrence, high postoperative mortality, the absence of extensive experience, and lack of universal indications for organ allocation preclude orthotopic liver transplantation as an option for most patients with unresectable NLM.

Abstract
BACKGROUND Yttrium-90 (90Y) radioembolization is a promising treatment option for unresectable neuroendocrine tumor liver metastases (NETLM). This study is the first to evaluate the prognostic variables that influenced radiologic response and survival in patients with unresectable NETLM who were treated with 90Y radioembolization. As a secondary outcome, the impact of this treatment on serologic toxicity was assessed. METHODS Forty-eight patients underwent resin-based 90Y radioembolization for unresectable NETLM at a single institution between December 2003 and May 2009. Patients were assessed radiologically and serologically at 1 month and then at 3 month intervals after treatment. Prognostic variables that affected response and survival were determined. The impact of this treatment on serologic toxicity over a 6-month period was assessed. DISCUSSION No patient was lost to follow-up. The median follow-up for the patients who were alive was 41 months. The median survival was 35 months (range: 5-63). On imaging follow-up, 7 patients (15%) had a complete response and 19 patients (40%) had a partial response to treatment. Eleven patients (23%) had stable disease and 11 patients (23%) had progressive disease. Five prognostic factors were associated with an improved survival: complete/partial response (P=0.003), low hepatic tumor burden (P=0.022), female gender (P=0.022), well-differentiated tumor (P=0.001), and absence of extra-hepatic metastasis (P<0.001). Three factors were associated with a complete/partial response: female gender (P=0.040), well-differentiated tumor (P<0.001) and low hepatic tumor burden (P=0.041). There was a significant increase in the level of alkaline phosphatase over the 6-month period (P<0.001). CONCLUSIONS 90Y radioembolization is a promising treatment option for unresectable NETLM. Patients with low hepatic tumor burden, well-differentiated tumor, female gender, and no extrahepatic disease benefit most from treatment.

Abstract
Neuroendocrine tumor (NET) metastases represent at this moment the only accepted indication of liver transplantation (LT) for liver secondaries. Between 1984-2007, nine (1.1%) of 824 adult LTs were performed because of NET. There were five well differentiated functioning NETs (four carcinoids and one gastrinoma), three well differentiated non functioning NETs and one poorly differentiated NET. Indications for LT were an invalidating unresectable tumor (4x), and/or a diffuse tumor localization (3x) and/or a refractory hormonal syndrome (5x). Median post-LT patient survival is 60.9 months (range 4.8-119). One-, 3- and 5-year actuarial survival rates are 88%, 77% and 33%; 1, 3 and 5 years disease free survival rates are 67%, 33% and 11%. Due to a more rigorous selection procedure, results improved since 2000; three out of five patients are alive disease-free at 78, 84 and 96 months. Review of these series together with a review of the literature reveals that results of LT for this oncological condition can be improved using better selection criteria, adapted immunosuppression and neo- and adjuvant surgical as well as medical treatment. LT should be considered earlier in the therapeutic algorithm of selected NET patients as it is the only therapy that can offer a cure.

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
Abstract
Background
90Y microsphere radioembolization is performed by injecting the microspheres through a hepatic artery catheter placed percutaneously via the femoral or brachial artery. This study assessed the efficacy of 90Y microsphere therapy for patients with unresectable neuroendocrine tumour liver metastases (NETLMs). Potential prognostic factors were analysed for their impact on overall survival.
Methods
A prospectively collected database for patients with NETLMs treated by 90Y microspheres in two centres from 2003 to 2008 was examined retrospectively. Serial radiographic evidence was collected during follow-up to assess response.
Results
Fifty-eight patients were included, 51 of whom had evaluable disease at most recent follow-up. Six patients achieved a complete response, 14 a partial response, 14 had stable disease and 17 had disease progression. Overall survival rates at 1, 2 and 3 years were 86, 58 and 47 per cent respectively; median survival was 36 (range 1–61) months. Extent of tumour involvement, radiographic response to treatment, extrahepatic disease and tumour grade were significant prognostic factors for overall survival.
Conclusion
90Y microsphere radioembolization achieved a radiographic response in a significant proportion of patients with NETLMs.

Abstract
The gastrointestinal tract is the largest neuroendocrine system in the body. Carcinoid tumors are amine precursor uptake decarboxylase (APUD) omas that arise from enterochromaffin cells throughout the gut. These tumors secrete discrete bioactive substances producing characteristic immunohistochemical patterns. Most tumors are asymptomatic and detected at late stages. Hepatic metastases are commonly responsible for carcinoid syndrome. The small bowel is the most common location of carcinoids. Computed tomography scan and magnetic resonance imaging are useful in the detection of these tumors. The measurement of bioactive amines is the initial diagnostic test. Various treatment options, including somatostatin analogs, interferon, chemotherapy, surgery, hepatic artery chemoembolization, and surgery have emerged in the past two decades. However, the incidence and prevalence of carcinoid tumors has increased, while mean survival time has not changed significantly. The lack of standardized classification, federal support, and an incomplete understanding of the complications of this disease are some of the impediments to progress in treatment.

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
Solid pseudo-papillary tumors (SPT) are rare primary tumors of the pancreas that primarily affect young women. They are of borderline malignancy, and, unlike other pancreatic malignancies, the prognosis after resection is quite good. However, metastatic disease does occur; the liver is the most common site of tumor dissemination. Herein we have reported a case of a 20-year-old woman who presented with multiple, bilateral liver metastases at 3 years after distal pancreatectomy for SPT of the body and tail of the pancreas. The patient underwent living donor liver transplantation (LDLT) and is alive and disease-free at 24 months after surgery. In this report, we discuss the treatment of liver metastases from SPT, with an emphasis on the possible role of orthotopic liver transplantation (OLT).
