Abstract
ABSTRACT Neuroendocrine neoplasms are a heterogeneous group of gastrointestinal and lung tumors. Their diverse clinical manifestations, variable locations, and heterogeneity present notable diagnostic challenges. This article delves into the imaging modalities vital for their detection and characterization. Computed tomography is essential for initial assessment and staging. At the same time, magnetic resonance imaging (MRI) is particularly adept for liver, pancreatic, osseous, and rectal imaging, offering superior soft tissue contrast. The article also highlights the limitations of these imaging techniques, such as MRI's inability to effectively evaluate the cortical bone and the questioned cost-effectiveness of computed tomography and MRI for detecting specific gastric lesions. By emphasizing the strengths and weaknesses of these imaging techniques, the review offers insights into optimizing their utilization for improved diagnosis, staging, and therapeutic management of neuroendocrine neoplasms.

Abstract
The present paper reflects the position of the Italian Association for Neuroendocrine Tumors (Itanet), the Italian Society of Gastroenterology (SIGE), and the Italian Society of Digestive Endoscopy (SIED) regarding the management of patients affected by gastric, duodenal, and rectal neuroendocrine neoplasms (NENs) amenable to endoscopic treatment. The key questions discussed in this paper are summarized in Table 1. Data were extracted from the MEDLINE database through searches; expert opinions and recommendations are provided in accordance with the available scientific evidence and the authors' expertise. Recommendations are presented alongside a level of evidence and grade of recommendation based on the GRADE system. This paper specifically focuses on subgroups of NENs considered suitable for endoscopic management according to current international guidelines: i. well-differentiated gastric neuroendocrine tumors (gNET) type 1 < 2 cm and selected cases of type 3; ii. well-differentiated duodenal, non-functioning, non-ampullary NET with size < 2 cm; and well-differentiated rectal NET with size < 2 cm.

Abstract
Background and study aims Endoscopic resection (ER) is recommended for the management of duodenal neuroendocrine tumors (D-NETs) confined to the submucosal layer, without lymph node or distant metastasis. While this is accepted practice for lesions < 10 mm, consensus for larger lesions remains unclear. Although endoscopic submucosal dissection (ESD) has been proposed as the preferred ER technique for DNETs ≥10 mm, there are limited data on efficacy and safety, particularly in the Western setting. Patients and methods We performed a retrospective analysis of patients with D-NETs who underwent ESD between 2012 and 2022 in three tertiary referral centers in Australia, France, and Belgium. Results Fourteen patients with 15 D-NETs were evaluated. Median patient age was 64 years (interquartile range [IQR] 58-70 years). All D-NETs were confined to the duodenal bulb. Median D-NET size was 10 mm (IQR 7-12 mm) and specimen size was 15 mm (IQR 15-20 mm). Median procedure time was 60 minutes (IQR 25-90 minutes). The rate of en bloc resection was 100%. Intra-procedural perforation occurred in four patients (26.7%), with all closed endoscopically without long-term sequelae. There were no episodes of clinically significant bleeding. No local recurrence, lymph node or distant metastasis was observed at a median follow-up of 19.9 months (IQR 10.3-49.3 months). Conclusions In experienced hands, ESD for D-NETs can achieve a 100% en bloc resection rate. There were no cases of local recurrence or distant metastatic spread, indicating that ESD may be a viable option for patients with D-NETs 10 to 15 mm that are not surgical candidates.

Cancers (Basel) 2023; 15:4175. [PMID: 37627203 PMCID: PMC10453187 DOI: 10.3390/cancers15164175] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Revised: 08/15/2023] [Accepted: 08/15/2023] [Indexed: 08/27/2023] Open
Abstract
Neuroendocrine neoplasms (NENs), also called neuroendocrine tumors (NETs), are relatively uncommon, heterogenous tumors primarily originating in the gastrointestinal tract. With the improvement in technology and increasing use of cross-sectional imaging and endoscopy, they are being discovered with increasing frequency. Although traditionally considered indolent tumors with good prognoses, some NENs exhibit aggressive behavior. Timely diagnosis, risk stratification, and management can often be a challenge. In general, small NENs without local invasion or lymphovascular involvement can often be managed using minimally invasive advanced endoscopic techniques, while larger lesions and those with evidence of lymphovascular invasion require surgery, systemic therapy, or a combination thereof. Ideal management requires a comprehensive and accurate understanding of the stage and grade of the tumor. With the recent advancements, a therapeutic advanced endoscopist can play a pivotal role in diagnosing, staging, and managing this rare condition. High-definition white light imaging and digital image enhancing technologies like narrow band imaging (NBI) in the newer endoscopes have improved the diagnostic accuracy of traditional endoscopy. The refinement of endoscopic ultrasound (EUS) over the past decade has revolutionized the role of endoscopy in diagnosing and managing various pathologies, including NENs. In addition to EUS-directed diagnostic biopsies, it also offers the ability to precisely assess the depth of invasion and lymphovascular involvement and thus stage NENs accurately. EUS-directed locoregional ablative therapies are increasingly recognized as highly effective, minimally invasive treatment modalities for NENs, particularly pancreatic NENs. Advanced endoscopic resection techniques like endoscopic submucosal dissection (ESD), endoscopic submucosal resection (EMR), and endoscopic full-thickness resection (EFTR) have been increasingly used over the past decade with excellent results in achieving curative resection of various early-stage gastrointestinal luminal lesions including NENs. In this article, we aim to delineate NENs of the different segments of the gastrointestinal (GI) tract (esophagus, gastric, pancreatic, and small and large intestine) and their management with emphasis on the endoscopic management of these tumors.

Expert Rev Gastroenterol Hepatol 2023; 17:785-793.

Abstract
INTRODUCTION Well-differentiated gastric, duodenal, and rectal neuroendocrine neoplasms (NETs) are rare diseases usually managed by endoscopic treatment. Although several endoscopic techniques are available, the number of patients with incomplete (R1) resection is significant. AREAS COVERED This review focuses on the meaning of incomplete R1 findings after endoscopic resection in type I gastric NETs; nonfunctioning, non-ampullary duodenal NETs; and small rectal NETs. Data were identified by MEDLINE database search without publication date limitation. EXPERT OPINION An incomplete R1 finding may have no significant impact on a patient's clinical outcome, particularly in small G1 type I gastric NETs, which have an indolent course. A 'stepwise approach,' which uses more advanced endoscopic techniques, or minimally invasive surgery may be justified to achieve complete margin-free resection. This approach must balance the tumor features and the procedure-related risk of complications, particularly in the duodenum, where the role of deep endoscopic resections is limited due to the thin duodenal wall. Gastric and rectal NETs that are incompletely removed after initial resection are more easily amenable to deep endoscopic techniques. However, this might not be necessary for patients with comorbidities, elderly, or both due to the uncertainty of how R1 finding impacts a patient's clinical outcome.

Abstract
PURPOSE OF REVIEW Our aim is to provide an overview of small bowel neuroendocrine tumours (NETs), clinical presentation, diagnosis algorithm and management options. We also highlight the latest evidence on management and suggest areas for future research. RECENT FINDINGS Dodecanetetraacetic acid (DOTATATE) scan can detect NETs with an improved sensitivity than when compared with an Octreotide scan. It is complimentary to small bowel endoscopy that provides mucosal views and allows the delineation of small lesions undetectable on imaging. Surgical resection is the best management modality even in metastatic disease. Prognosis can be improved with the administration of somatostatin analogues and Evarolimus as second-line therapies. SUMMARY NETs are heterogenous tumours affecting most commonly the distal small bowel as single or multiple lesions. Their secretary behaviour can lead to symptoms, most commonly diarrhoea and weight loss. Metastases to the liver are associated with carcinoid syndrome.

Abstract
PURPOSE to collect data from real-life experiences of the management of type 3 g-NETs and identify possible prognostic factors that may impact the decision-making process. METHODS We performed a systematic review of the literature on type 3 g-NET management using the PubMed, MEDLINE, and Embase databases. We included cohort studies, case series, and case reports written in the English language. RESULTS We selected 31 out of 556 articles from between 2001 and 2022. In 2 out of the 31 studies, a 10 mm and 20 mm cut-off size were respectively associated with a higher risk of gastric wall infiltration and/or lymph node and distant metastasis at diagnosis. The selected studies reported a higher risk of lymph node or distant metastasis at diagnosis in the case of muscularis propria infiltration or beyond, irrespective of the dimensions or grading. From these findings, size, grading, and gastric wall infiltration seem to be the most relevant factors in management staff making choices and prognoses of type 3 g-NET patients. We produced a hypothetical flowchart for a standardized approach to these rare diseases. CONCLUSION Further prospective analyses are needed to validate the prognostic impact of the use of size, grading, and gastric wall infiltration as prognostic factors in the management of type 3 g-NETs.

Abstract
Subepithelial lesions, formerly known as subepithelial tumors, are incidentally discovered protrusions throughout the gastrointestinal tract with normal overlying mucosa. Studies related to the diagnosis and therapy methods are limited due to the low incidence and malignant potential of these lesions. They commonly originating from the second, third, and fourth layers (muscularis mucosa, submucosa, and muscularis propria) of the gastrointestinal wall. They are reported to be more prevalent in the stomach and esophagus than small intestine and colon. Subepithelial lesions in the stomach and duodenum are more prone to malignancy than the lesions in the esophagus. Despite different strategies in the management of subepithelial lesions based on their size and location, there is still not a unique consensus on the issue. In this review, we have attempted to introduce the most practical approach to managing gastrointestinal subepithelial lesions based on current guidelines.

Abstract
Introduction: Duodenal neuroendocrine tumors (DNETs) smaller than 1 cm in diameter, without invasion to the muscularis propria, have a low risk of metastasis. Therefore, DNETs are frequently resected endoscopically. However, among the various procedures, the best fit for DNET in terms of feasibility, effectiveness, and simplicity is unclear. Methods: Patients with DNET who underwent endoscopic submucosal resection using a ligation device (ESMR-L) at Kanagawa Cancer Center between May 2003 and December 2020 were studied retrospectively to evaluate clinical characteristics and short-term and long-term outcomes. Results: Eleven consecutive patients with 12 lesions were treated with 12 sessions of ESMR-L. Lesions were discovered in patients at a median age of 68 (range, 50–83) years. One patient had two lesions at the time of the initial ESMR-L session. Eleven of the 12 lesions (91.7%) existed in the duodenal bulb, of which 10 (83.3%) were in the anterior wall, and the remaining one (8.3%) existed in the descending part of the duodenum. The en bloc and R0 resection rates were 100% and 75%, respectively. The rates of bleeding and perforation were both 0%. Among the four patients who had non-curative resections, two patients underwent additional surgery after ESMR-L. One patient had a local remnant tumor, and the other had lymph node metastasis. In cases of local remnant tumors, the vertical margin was positive in the ESMR-L specimen. In that case, ligation by the O-ring was insufficient, retrospectively. All patients had no recurrence during the median follow-up period of 5.7 years. Discussion: ESMR-L was the best fit for DNET within the indications for endoscopic resection. It is a simple procedure that enables easy and complete resection of DNETs without complications.

ZusammenfassungNeuroendokrine Tumoren des Verdauungstraktes (GEP-NET) sind eine seltene Tumorentität, die häufig als Zufallsbefund diagnostiziert werden. Ein großer Teil dieser Zufallsdiagnosen wird im
Rahmen einer endoskopischen Untersuchung gestellt. Während die vollständige Entfernung des Tumors im Sinne einer kurativen chirurgischen Resektion nach onkologischen Kriterien das
Standardvorgehen für lokalisierte Tumorerkrankungen ist, kann bei kleinen Tumoren ohne Hinweis und Risiko für eine lymphogene Metastasierung eine endoskopische Abtragung in gleicher
Intention erfolgen. Während dies für Magen-, Duodenum- und Rektum-NET der Standard ist, sollten NET des Jejunums und Ileums aufgrund der hohen Metastasierungsrate trotz geringer Tumorgröße
regelhaft nicht endoskopisch angegangen werden. Die Grenze für eine endoskopische Resektion ergibt sich sowohl durch die technische Machbarkeit im Sinne des Erreichens einer R0-Resektion,
der erwarteten Komplikationen im Sinne von Blutung und Perforationen als auch durch das vermutete Risiko für eine lymphogene Metastasierung. Generell wird eine endoskopische Resektion bei
Befunden < 1 cm regelhaft empfohlen, da sowohl die gute technische Machbarkeit als auch das geringe Metastasierungsrisiko für eine endoskopische Resektion sprechen. Bei allen Befunden
über 2 cm Größe sind sowohl die technischen Erfolgsaussichten so niedrig als auch das Metastasierungsrisiko so hoch, dass in dieser Situation regelhaft ein chirurgisches Vorgehen erfolgen
sollte. Es bleibt somit ein Graubereich bei der Tumorgröße zwischen 1 und 2 cm, wo sowohl endoskopische, aber auch chirurgische Resektionsverfahren sinnvoll eingesetzt werden können.
Zunehmend kommen auch gemeinsame Eingriffe im Sinne eines endoskopisch-laparoskopischen Rendezvous-Verfahrens zum Einsatz – insbesondere im Duodenum bieten sich diese Eingriffe an, um eine
minimale Resektion mit größtmöglicher R0-Erfolgsrate und niedriger Perforationsrate zu erreichen.

Abstract
Background Gastrectomy with lymphadenectomy is recommended for early gastric Neuroendocrine carcinoma (G-NEC). We attempted to determine the prevalence and risk factors of metastasis of T1 G-NEC and compare the long-term survival of patients after receiving endoscopic therapy (ET) and radical surgery. Methods In this study, 205 patients in total with T1 G-NEC were collected from the Surveillance Epidemiology and End Result database. Independent predictors of metastasis were identified by Logistic regression analysis, followed by the calculation of both cancer-specific survival (CSS) and overall survival (OS). Results Twenty-five patients (12.2%) were burdened with metastasis at initial diagnosis, with a prevalence of 5.2% (3/58) in mucosa lesions and 16.2% (16/99) in submucosa lesions (P = 0.045). No metastasis was detected in lesions with mucosa involvement and tumors ≦ 20 mm (0%, 0/49). The most significant risk factor for metastasis was tumors > 20 mm [odds ratio (OR) 18.64; 95% confidence interval (CI) 4.01–86.68; P < 0.001]. For patients with T1N0M0 G-NEC who received ET or surgery, the 10-year OS was similar between the mucosa extension and submucosa extension groups, which was 91.56% in ET group vs 87.50% in surgery group (P = 0.62) and 57.33% vs 77.83% (P = 0.11), respectively. In addition, the 10-year CSS was also similar between the mucosa extension and submucosa extension groups with 97.30% in ET vs 100% in surgery (P = 0.51) and 97.62% vs 86.49% (P = 0.65). Conclusions In G-NEC, tumors > 20 mm were considered as the most significant risk factor for metastasis. ET seemed adequate for the lesions with mucosa involvement and size ≦ 2 cm.

Abstract
1: ESGE recommends endoscopic ultrasonography (EUS) as the best tool to characterize subepithelial lesion (SEL) features (size, location, originating layer, echogenicity, shape), but EUS alone is not able to distinguish among all types of SEL.Strong recommendation, moderate quality evidence. 2: ESGE suggests providing tissue diagnosis for all SELs with features suggestive of gastrointestinal stromal tumor (GIST) if they are of size > 20 mm, or have high risk stigmata, or require surgical resection or oncological treatment.Weak recommendation, very low quality evidence. 3: ESGE recommends EUS-guided fine-needle biopsy (EUS-FNB) or mucosal incision-assisted biopsy (MIAB) equally for tissue diagnosis of SELs ≥ 20 mm in size.Strong recommendation, moderate quality evidence. 4: ESGE recommends against surveillance of asymptomatic gastrointestinal (GI) tract leiomyomas, lipomas, heterotopic pancreas, granular cell tumors, schwannomas, and glomus tumors, if the diagnosis is clear.Strong recommendation, moderate quality evidence. 5: ESGE suggests surveillance of asymptomatic esophageal and gastric SELs without definite diagnosis, with esophagogastroduodenoscopy (EGD) at 3-6 months, and then at 2-3-year intervals for lesions < 10 mm in size, and at 1-2-year intervals for lesions 10-20 mm in size. For asymptomatic SELs > 20 mm in size that are not resected, ESGE suggests surveillance with EGD plus EUS at 6 months and then at 6-12-month intervals.Weak recommendation, very low quality evidence. 6: ESGE recommends endoscopic resection for type 1 gastric neuroendocrine neoplasms (g-NENs) if they grow larger than 10 mm. The choice of resection technique should depend on size, depth of invasion, and location in the stomach.Strong recommendation, low quality evidence. 7: ESGE suggests considering removal of histologically proven gastric GISTs smaller than 20 mm as an alternative to surveillance. The decision to resect should be discussed in a multidisciplinary meeting. The choice of technique should depend on size, location, and local expertise.Weak recommendation, very low quality evidence. 8: ESGE suggests that, to avoid unnecessary follow-up, endoscopic resection is an option for gastric SELs smaller than 20 mm and of unknown histology after failure of attempts to obtain diagnosis.Weak recommendation, very low quality evidence. 9: ESGE recommends basing the surveillance strategy on the type and completeness of resection. After curative resection of benign SELs no follow-up is advised, except for type 1 gastric NEN for which surveillance at 1-2 years is advised.Strong recommendation, low quality evidence. 10: For lower or upper GI NEN with a positive or indeterminate margin at resection, ESGE recommends repeating endoscopy at 3-6 months and another attempt at endoscopic resection in the case of residual disease.Strong recommendation, low quality evidence.

Efficacy of Endoscopic Submucosal Dissection for Superficial Gastric Neoplasia in a Large Cohort in North America. Clin Gastroenterol Hepatol 2021; 19:1611-1619.e1. [PMID: 32565290 DOI: 10.1016/j.cgh.2020.06.023] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Revised: 06/07/2020] [Accepted: 06/11/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Endoscopic submucosal dissection (ESD) is a widely accepted treatment option for superficial gastric neoplasia in Asia, but there are few data on outcomes of gastric ESD from North America. We aimed to evaluate the safety and efficacy of gastric ESD in North America. METHODS We analyzed data from 347 patients who underwent gastric ESD at 25 centers, from 2010 through 2019. We collected data on patient demographics, lesion characteristics, procedure details and related adverse events, treatment outcomes, local recurrence, and vital status at the last follow up. For the 277 patients with available follow-up data, the median interval between initial ESD and last clinical or endoscopic evaluation was 364 days. The primary endpoint was the rate of en bloc and R0 resection. Secondary outcomes included curative resection, rates of adverse events and recurrence, and gastric cancer-related death. RESULTS Ninety patients (26%) had low-grade adenomas or dysplasia, 82 patients (24%) had high-grade dysplasia, 139 patients (40%) had early gastric cancer, and 36 patients (10%) had neuroendocrine tumors. Proportions of en bloc and R0 resection for all lesions were 92%/82%, for early gastric cancers were 94%/75%, for adenomas and low-grade dysplasia were 93%/ 92%, for high-grade dysplasia were 89%/ 87%, and for neuroendocrine tumors were 92%/75%. Intraprocedural perforation occurred in 6.6% of patients; 82% of these were treated successfully with endoscopic therapy. Delayed bleeding occurred in 2.6% of patients. No delayed perforation or procedure-related deaths were observed. There were local recurrences in 3.9% of cases; all occurred after non-curative ESD resection. Metachronous lesions were identified in 14 patients (6.9%). One of 277 patients with clinical follow up died of metachronous gastric cancer that occurred 2.5 years after the initial ESD. CONCLUSIONS ESD is a highly effective treatment for superficial gastric neoplasia and should be considered as a viable option for patients in North America. The risk of local recurrence is low and occurs exclusively after non-curative resection. Careful endoscopic surveillance is necessary to identify and treat metachronous lesions.

Abstract
Small bowel neuroendocrine tumors (NETs) represent approximately one-third of NETs of the gastrointestinal tract, and their incidence is increasing. When determining if endoscopic resection is appropriate, endoscopic ultrasound is used to assess the lesion size and depth of invasion for duodenal NETs. A number of techniques, including endoscopic mucosal resection (EMR), band-assisted EMR (band-EMR), endoscopic submucosal dissection (ESD), and over-the-scope clip-assisted endoscopic full-thickness resection (EFTR), have been studied; however, the best technique for endoscopic resection remains unclear. The vast majority of currently available data are retrospective, and prospective studies with longer follow-up times are required. For jejunal and ileal NETs, endoscopic techniques such as video capsule endoscopy (VCE) and balloon enteroscopy (BE) assist in diagnosis. This includes localization of the primary NET in metastatic disease where initial workup has been negative, and the identification of multifocal disease, which may change management and prognostication.

Abstract
INTRODUCTION Although duodenal neuroendocrine tumors (dNETs) are rare, the incidence, particularly for lesions ≤ 10 mm, continues to rise with the advent of widely available, high-quality endoscopy. Given their rarity and controversy regarding prognostication factors, limited guidelines exist for resection of well-differentiated, ≤ 20-mm dNETs. Importantly, lesions ≤ 10 mm in a duodenal location are ideal for consideration of endoscopic management given both morbidity and technical challenges associated with surgery and their accessibility to a wide range of endoscopic techniques. OBJECTIVES The primary objective of this study was to demonstrate the safety and efficacy of the endoscopic resection of dNETs <10 mm in a case series and literature review. METHODS We performed a literature review and present a series of nine cases to demonstrate the viability of endoscopic resection for diminutive dNETs as an alternative to surgery. RESULTS Our case series included nine well-differentiated diminutive dNETs in seven patients, the majority resected using endoscopic mucosal resection (EMR), 67%, and there was no residual disease at follow-up. The literature review of 178 patients demonstrated that EMR was the most used method of resection of diminutive dNETs, 81%, compared to endoscopic submucosal dissection, 19%. The most common complication was intraoperative bleeding in 9.55%, and only 2.25% of patients had recurrence. CONCLUSION While complications may arise with endoscopic resection of diminutive dNETs, they are usually managed endoscopically and compare favorably with the literature on surgical complication rates and typically result in shorter hospitalizations.

Abstract
BACKGROUND Endoscopic resection is considered the treatment of choice for type I gastric neuroendocrine neoplasia (gNEN) given its indolent behaviour; however, the favoured endoscopic technique to remove these tumours is not well established. AIMS This systematic review is aimed at investigating the best endoscopic management for type I gNEN. METHODS PubMed Central/Medline and Scopus were systematically searched for records up to August 31, 2020. RESULTS After screening the 675 retrieved records, 6 studies were selected for the final analysis. The main endoscopic resection techniques described were endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD). Overall, 112 gNENs were removed by EMR and 77 by ESD. Both techniques showed similar results for complete and en bloc resection (97.4% and 98.7%; 92.3% and 96.3% with ESD and EMR, respectively). ESD was associated with a higher rate of complications than EMR (11.7% vs. 5.4%), but this difference was not statistically significant (p = 0.17). The rates of recurrence during follow-up were 18.2% and 11.5% for EMR and ESD, respectively. CONCLUSIONS To date, there are no sufficient data showing superiority of a given endoscopic technique over others. Both ESD and EMR seem to be effective in the management of type I gNEN, with a relatively low rate of recurrence.

Abstract
Guidelines have differed in their opinion regarding the indications for endoscopic resection of gastric-neuroendocrine neoplasms (g-NENs) and duodenal-NENs (d-NENs). We examined the association between size and lymph node metastasis (LNM) to identify candidates most suitable for endoscopic resection. We identified 706 patients with T1/T2 g-NENs and 621 patients with T1/T2 d-NENs from the SEER database. The prevalence of LNM and risk factors associated with LNM were analyzed. LNM was present in 8.1% of patients with gastroduodenal neuroendocrine tumors (NETs) and 31.6% of patients with neuroendocrine carcinomas (NECs). Multivariate logistic regression indicated that tumor size >10mm, greater invasion depth, and poor differentiation were independently associated with LNM. In addition, the percentage of g-NETs invading submucosa with LNM increased with tumor size (≤10 mm,3.9%;11-20 mm,8.6%;>20 mm,16.1%). However, in contrast to the low LNM risk in patients with small g-NETs (≤10 mm), we found that LNM rate exceeded 5% even for patients with small submucosal-infiltrating d-NETs. Among patients with nodal-negative g-NETs, the cause specific survival (CSS) was similar for those who received surgical resection and endoscopic resection. Among patients with d-NETs, the CSS was better for those who received endoscopic resection. In conclusion, patients with d-NETs had a higher probability of LNM than those with g-NETs. Endoscopic resection can be utilized for curative treatment of submucosa-infiltrating g-NETs and intramucosal d-NETs when the size is 10 mm or less. These results reinforce the need to search for LNM in lesions that are larger than 10 mm.

Abstract
BACKGROUND As a subtype of esophageal neuroendocrine neoplasms (ENENs), esophageal neuroendocrine carcinoma (ENEC) is rare. ENEC can be poorly differentiated and highly aggressive. This study aims to illustrate the incidence, treatment, and prognosis of ENEC by using a population-based database. METHODS We collected clinicopathological data [1975-2016] of ENEC, esophageal adenocarcinoma (EACA), and esophageal squamous cell carcinoma (ESqCC) from the Surveillance, Epidemiology and End Results (SEER) database, and analyzed their incidence, treatment, and prognosis. RESULTS A total of 60,238 cases were in our study cohort, including ENEC (n=686), EACA (n=26,575), and ESqCC (n=32,977). The incidence of ENEC in 2016 was 0.044 per 100,000 persons. The tumor grade of ENEC was significantly higher than that of EACA and ESqCC (P<0.001). Both cancer-specific survival (CSS) and overall survival (OS) of ENEC were significantly worse than those of EACA and ESqCC (P<0.001). Kaplan-Meier analysis showed significant improvement of CSS and OS by surgery, radiotherapy, and chemotherapy (all P<0.001). Besides, compared with monotherapies, combinational therapies brought more benefits to both CSS and OS of patients with ENEC. CONCLUSIONS Our population-based evidence revealed that ENEC, as a rare cancer, had a worse prognosis, compared with EACA and ESqCC. Surgery, chemotherapy, and radiotherapy can all improve the prognosis of ENEC patients. Combinational therapy can yield a better prognosis than monotherapy.

Abstract
BACKGROUND & AIMS Esophageal neuroendocrine tumors (NET) are very rare and mostly carcinomic, carrying poor prognosis. There is still no guideline or consensus on the treatment for esophageal NET. METHODS Patients with histologically-proven esophageal neuroendocrine tumor were recruited from 9 hospitals in Taiwan between 2002 and 2017. Clinical, laboratory, radiological, endoscopic, pathological data, treatment strategies, follow-up periods, and survivals were collected retrospectively. RESULTS In total, 39 esophageal NET were analyzed and 38 were neuroendocrine carcinoma (NEC). Sixteen (41%) patients had mixed components with either adenocarcinoma (N = 9, 23%) or squamous-cell carcinoma (SCC) (N = 7, 18%). 64.1% of the patients experienced dysphagia and ulcerative mass was the most comment endoscopic finding. There was a higher proportion of drinkers (54.1%), betel chewers (21.6%) and smokers (64.9%) among the patients than in the general population in Taiwan. Five patients (12.8%) had been diagnosed with other cancers. Definite chemoradiotherapy (N = 14, 35.9%) and surgery (N = 7, 17.9%) were the major treatment. Patients with Ki-67% above the median level (50%) in the tumors tended to have worse survival (P = 0.06). However, presence of mixed component was not a significant survival predictor in our study (P = 0.56). CONCLUSION Mixed component of an esophageal NET is commonly observed. Staged workup and the principle of treatment can follow that for the common cancer type of esophagus. The risk factors and behaviors of esophageal NEC in Taiwan seem to be similar to that of esophageal SCC.

Abstract
BACKGROUND Neuroendocrine tumours (NETs) of the stomach and duodenum are rare, but are increasing in incidence. Optimal management of localised, low-grade gastric and duodenal NETs remains controversial. AIMS To systematically review recent literature that has evaluated the management of localised low-grade gastric and duodenal NETs. METHODS A systematic literature search was conducted. Articles were screened and eligible articles fully assessed. Additional articles were identified through the included articles' reference lists. RESULTS Several relevant retrospective case series were identified, but there was considerable heterogeneity between studies and they reported a variety of parameters. Type I gastric NETs had an excellent prognosis and conservative management approaches such as endoscopic surveillance/resection were appropriate in most cases. Many type III gastric NETs were low grade and appeared to have a better prognosis than has previously been appreciated. Endoscopic rather than surgical resection was therefore effective in some patients who had small, low-grade tumours. Duodenal NETs were more heterogenous. Endoscopic resection was generally safe and effective in patients who had small, low-grade, nonfunctional, non-ampullary tumours. However, some patients, especially those with larger or ampullary duodenal NETs, required surgical resection. CONCLUSIONS Most type I gastric NETs behave indolently and surgical resection is only rarely indicated. Some type III gastric and duodenal NETs have a worse prognosis, but selected patients who have small, localised, nonfunctional, low-grade tumours are adequately and safely treated by endoscopic resection. Due to the complexity of this area, a multidisciplinary approach to management is strongly recommended.

Abstract
Background Endoscopic resection is recommended for non-ampullary duodenal neuroendocrine tumors (NAD-NETs) ≤10 mm in diameter and confined to the submucosal layer, without lymph node or distant metastasis. However, the efficacy and safety of endoscopic submucosal dissection (ESD) for NAD-NET remains unclear. The aim of this study was to assess the short-term efficacy and safety and the long-term outcomes of ESD for NAD-NET. Methods Eight patients with 8 NAD-NETs who underwent ESD between 2015 and 2018 were included. The indications for ESD were: i) tumor ≤10 mm in diameter; ii) NET G1; iii) confined to the submucosal layer; and iv) without lymph node or distant metastasis. We retrospectively assessed the short- and long-term outcomes and safety. Results The median patient age was 69 (48-76) years. All tumors were located in the duodenal bulb and showed 0-Is morphology. The median size was 6.4 (3-9.3) mm. The rates of en bloc resection, histologically free horizontal and vertical margins, and curative resection were 100%, 88%, and 88%, respectively. Intraoperative and postoperative perforation each occurred in 13% of patients, all of whom were treated conservatively and avoided emergent surgery. Delayed bleeding was not observed. No local, lymph node or distant recurrence was observed during a median follow-up period of 34 (18.5-62.5) months. Conclusions The rates of en bloc and curative resection, and histologically free margins were sufficiently high. Although intraoperative and postoperative perforations occurred, emergency surgery was not needed. The results show that ESD is an efficacious and safe treatment for NAD-NET.

Abstract
BACKGROUND To date, the histopathological parameters predicting the risk of lymph node (LN) metastases and local recurrence, associated mortality and appropriateness of endoscopic or surgical resection in patients with gastric neuroendocrine neoplasms type 1 (GNENs1) have not been fully elucidated.
AIM To determine the rate of LN metastases and its impact in survival in patients with GNEN1 in relation to certain clinico-pathological parameters.
METHODS The PubMed, EMBASE, Cochrane Library, Web of Science and Scopus databases were searched through January 2019. The quality of the included studies and risk of bias were assessed using the Newcastle-Ottawa Scale (NOS) in accordance with the Cochrane guidelines. A random effects model and pooled odds ratios (OR) with 95%CI were applied for the quantitative meta-analysis.
RESULTS We screened 2933 articles. Thirteen studies with 769 unique patients with GNEN1 were included. Overall, the rate of metastasis to locoregional LNs was 3.3% (25/769). The rate of LN metastases with a cut-off size of 10 mm was 15.3% for lesions > 10 mm (vs 0.8% for lesions < 10 mm) with a random-effects OR of 10.5 (95%CI: 1.4 -80.8; heterogeneity: P = 0.126; I2 = 47.5%). Invasion of the muscularis propria was identified as a predictor for LN metastases (OR: 17.2; 95%CI: 1.8-161.1; heterogeneity: P = 0.165; I2 = 44.5%), whereas grade was not clearly associated with LN metastases (OR: 2; 95%CI: 0.3-11.6; heterogeneity: P = 0.304; I2 = 17.4%). With regard to GNEN1 local recurrence, scarce data were available. The 5-year disease-specific survival for patients with and without LN metastases was 100% in most available studies irrespective of the type of intervention. Surgical resection was linked to a lower risk of recurrence (OR: 0.3; 95%CI: 0.1-1.1; heterogeneity: P = 0.173; I2 = 31.9%). The reported complication rates of endoscopic and surgical intervention were 0.6 and 3.8%, respectively.
CONCLUSION This meta-analysis confirms that tumor size ≥ 10 mm and invasion of the muscularis propria are linked to a higher risk of LN metastases in patients with GNEN1. Overall, the metastatic propensity of GNEN1 is low with favorable 5-year disease-specific survival rates reported; hence, no clear evidence of the prognostic value of LN positivity is available. Additionally, there is a lack of evidence supporting the prediction of local recurrence in GNEN1, even if surgery was more often a definitive treatment.

Abstract
Synchronous early gastric cancer/neuroendocrine tumor (NET) associated with autoimmune gastritis is rare, and its endoscopic and pathological features remain poorly described. Screening esophagogastroduodenoscopy performed on a 71-year-old man revealed a whitish, superficial elevated lesion and a submucosal tumor with redness that appeared slightly centrally depressed. Endoscopic submucosal dissection (ESD) allowed these lesions to be resected with negative margins, and they were diagnosed as tubular adenocarcinoma, well-differentiated type (tub1), pT1a (M) and NET G1, pT1b (SM). To our knowledge, this is the first report describing the endoscopic and pathological findings of synchronous early gastric cancer/NET that was amenable to complete resection with ESD.

Abstract
Zollinger-Ellison syndrome (ZES) is characterized by gastric acid hypersecretion causing severe recurrent acid-related peptic disease. Excessive secretion of gastrin can now be effectively controlled with powerful proton pump inhibitors, but surgical management to control gastrinoma itself remains controversial. Based on a thorough literature review, we design a surgical algorithm for ZES and list some significant consensus findings and recommendations: (1) For sporadic ZES, surgery should be routinely undertaken as early as possible not only for patients with a precisely localized diagnosis but also for those with negative imaging findings. The surgical approach for sporadic ZES depends on the lesion location (including the duodenum, pancreas, lymph nodes, hepatobiliary tract, stomach, and some extremely rare sites such as the ovaries, heart, omentum, and jejunum). Intraoperative liver exploration and lymphadenectomy should be routinely performed; (2) For multiple endocrine neoplasia type 1-related ZES (MEN1/ZES), surgery should not be performed routinely except for lesions > 2 cm. An attempt to perform radical resection (pancreaticoduodenectomy followed by lymphadenectomy) can be made. The ameliorating effect of parathyroid surgery should be considered, and parathyroidectomy should be performed first before any abdominal surgery for ZES; and (3) For hepatic metastatic disease, hepatic resection should be routinely performed. Currently, liver transplantation is still considered an investigational therapeutic approach for ZES. Well-designed prospective studies are desperately needed to further verify and modify the current considerations.

Abstract
Significant augmentation of the incidence of duodenal neuroendocrine tumors duodenum has been observed in recent decades. There are 5 histological types of these tumors: gastrinoma (50-60%), somatostatin-producing tumor (15%), inactive serotonin-containing tumors (20%), poorly differentiated neuroendocrine carcinoma (<3%) and gangliocytic paraganglioma (<2%). The majority of tumors are localized within the bulb and postbulbar part of duodenum, 20% are found in periampular area. Treatment strategy depends on dimensions, localization, histological class, stage and type of tumor. It is believed that endoscopic resection is permissible for small inactive tumors (G1) located above major duodenal papilla. The majority of other neoplasms requires surgical resection. Personal experience of various surgeons is limited by small group of patients. Therefore, it is necessary to summarize results for selection of optimal treatment.

Abstract
INTRODUCTION Gastric neuroendocrine carcinoma (NEC) is rare. It is considered to be aggressive and has a poor prognosis since the diagnosis is usually made at its advanced stage. However, the survival rate is increased in some early gastric NECs. This study showed a case and reviewed the clinical characteristics of early NECs in stomach. PATIENT CONCERNS A 38-year-old man displayed no symptoms and underwent the gastric endoscopy test for his health examination, which showed a red slightly depressed lesion 1.0 cm in size on the lesser curvature of gastric cardia. Magnifying endoscopy with narrow-band imaging (NBI) revealed a clear demarcation and an irregular mesh in vessels within the depressed area. The background mucosa was negative for atrophic gastritis and Helicobacter Pylori infection. A contrast-enhanced computed tomography (CT) scan disclosed no obvious thickening of stomach and lymphadenopathy. Blood tests and physical examination were unremarkable. He had not received any surgical treatment and denied a family history of cancer and any genetic disorders. The pathologic result of biopsy from the lesion was suspicious of superficial carcinoma. Then endoscopic submucosal dissection (ESD) was performed. DIAGNOSIS Gastric NEC G3 in the early stage (T1aN0M0). INTERVENTIONS Concerning this patient's situation, we considered the ESD as a curable treatment. And no radical surgery or adjuvant chemotherapy was arranged. OUTCOMES The patient is doing well and displays no recurrence for 11 months, who is still in follow-up. LESSONS SUBSECTIONS AS PER STYLE The early diagnosis and effective treatment by endoscopy would contribute to improve the prognosis of gastric NECs.

Abstract
Objective: Endoscopy is the main method to treat gastrointestinal neuroendocrine tumors (GI-NETs), but the specific indications are still controversial. We aim to investigate the clinical outcomes of GI-NETs patients who experienced endoscopic submucosal dissection (ESD). Methods: We retrospectively reviewed the clinical features and prognosis of 65 GI-NETs patients who underwent ESD between 2008 and 2018. Results: A total of 65 patients diagnosed with GI-NETs pathologically, bearing 75 lesions, were found by endoscopy incidentally for other symptoms. The locations of these lesions were stomach (n = 24), duodenal bulb (n = 4) and rectum (n = 47). The diameter of 75 tumors were as follows: size ≤ 1 cm (78.7%), 1 cm < size ≤ 2 cm (17.3%), 2 cm < size ≤ 3.5 cm (4.0%). Endoscopic ultrasonography (EUS) suggested that 72 lesions were confined to submucosa and 3 lesions invaded into muscularis propria. The rates of en bloc resection and complete resection were all 100% and the rates of intraoperative bleeding and perforation were 2.7% and 1.3%, respectively. None of the 65 patients had lymph nodes and distant metastasis during the period of study. Conclusion: For GI-NETs without lymph nodes and distant metastases, the lesion confined to submucosa with the diameter ≤1 cm is absolute indication of ESD. For rectal neuroendocrine tumors limited in submucosa with the diameter between 1 and 2 cm, and Type 1 gastric neuroendocrine tumors predicted to be T2, ESD should be prioritized to preserve gastrointestinal volume and function at initial treatment.

Abstract
INTRODUCTION Neuroendocrine tumors (NETs) are a heterogeneous group of neoplasms composed of cells containing dense-core neuroendocrine secretory granules in their cytoplasm. NETs of the esophagus are exceedingly uncommon, with a parallel absence of data published on clinical features, prognosis, and proposed treatment strategies. METHODS As relevant classification is not well-established, knowledge acquired in NETs of lung and gastrointestinal sites usually guides esophageal NET management. Associated subtypes are divided based upon shared neuroendocrine features into small and large cell NET, typical and atypical carcinoid. RESULTS Common presenting symptoms include dysphagia, abdominal discomfort, weight loss, melena, and on occasion, signs of carcinoid syndrome. Endoscopic findings describe a polypoid, nodular elevated lesion with an overlying surface depicted as mostly smooth and glistening. Disease metastasis is assessed using anatomical imaging, including computed tomography (CT), endoscopic ultrasonography (EUS), and positron emission tomography (PET)-CT. Prognosis is influenced by the extent of lymph node metastasis and potential lymphovascular invasion. Furthermore, proliferative activity, estimated using mitotic count or Ki-67 immunostaining, has been suggested as a significant prognostic parameter. CONCLUSION Therapeutic approach depends on clinical staging. Nevertheless, currently, a specific treatment algorithm for esophageal NETs has not been elucidated. Endoscopic resection has been proposed in NETs less than 1 cm in size with absence of regional lymph node metastasis, while surgical excision combined with adjuvant chemotherapy remains the treatment of choice.

Abstract
Upper gastrointestinal neuroendocrine tumors (NETs) are rare tumors which are increasingly recognised by practising endoscopists. After confirmation by endoscopic biopsies of these focal lesions, many questions may arise. As NETs are less frequently encountered compared to other malignancies or gastrointestinal pathology, many endoscopists may not fully understand the natural history, diagnosis and management of these tumors. In this review, we aim to update the practising endoscopist on the key clinical features and management of patients with upper gastrointestinal NET.

Abstract
INTRODUCTION Nonfunctional, non-ampullary duodenal neuroendocrine tumors (dNETs) are rare neoplasms, and specific treatment recommendations are less clear than for other NETs. MATERIALS AND METHODS We performed a retrospective review of patients (pts) with a diagnosis of dNET, excluding hormonally functional, ampullary, and high-grade tumors. Clinical data were evaluated to identify factors that might impact clinical staging and predictors of metastases. RESULTS Thirty-six pts were identified. Surgical resection was performed in 28 and endoscopic resection in 8. LNs were included in specimens of 19/28 (68 %) pts who underwent surgical resection (median #LNs 5, range 1-12). Of these 19 pts, 5 (26 %) were found to be LN+. Of LN+ pts, all had tumors ≤2 cm. When compared to LN- pts, LN+ pts were more likely to have muscularis propria (MP) invasion (80 vs. 23 %, p = 0.04). Tumor size, tumor grade, lymphovascular invasion, and multifocality were similar between LN+ and LN- patients. No pt was found to have distant metastases. Heterogeneity in clinical staging modalities and small number of pts evaluated prohibited meaningful analysis of most appropriate preoperative imaging. At a median follow-up of 25 months (range 9-139), no patient developed recurrence or experienced disease-specific death. CONCLUSIONS Non-functional, non-ampullary dNETs, particularly those with MP invasion, have a propensity to metastasize to regional LNs. However, these neoplasms appear to have a favorable prognosis. Further evaluation of preoperative imaging is required to better determine most appropriate clinical staging. A suggested workup and management strategy for prospective evaluation is proposed.

Abstract
Esophageal neuroendocrine neoplasms are rare. With the improvement and popularization of diagnostic methods, the morbidity statistics have increased annually in recent years. There are currently no treatment guidelines for esophageal neuroendocrine neoplasms, and surgery is the only cure. This usually involves radical surgery when the tumor is limited to the primary site or when only regional lymph node metastasis occurs. Surgical treatment is key to treating esophageal neuroendocrine neoplasms, but combined treatment with chemotherapy and radiotherapy can significantly improve patient survival. The effect of radiotherapy alone on this disease is poor. However, targeted endocrine therapy can improve endocrine hormone symptoms. The prognosis of patients with esophageal neuroendocrine neoplasms is mainly determined by the pathological stage. With the development of molecular biology techniques, the combination of targeted drugs and traditional chemotherapy is expected to provide novel ideas and directions for the treatment of esophageal neuroendocrine neoplasms in the coming years. In this article, the status of esophageal neuroendocrine tumor treatments was reviewed in detail.

Abstract
Background and Aims. Endoscopic submucosal dissection (ESD) outcomes have traditionally been reported from high volume centers in East Asia. Data from low volume centers in other parts of Asia remain sparse. Methods. A retrospective survey with a structured questionnaire of 5 tertiary centers in 3 countries in South East Asia was conducted. Details of training and clinical outcomes of ESD cases, with follow-up data from these centers, were analyzed. Results. Seven endoscopists from the 5 centers performed a total of 35 cases of ESD in the upper gastrointestinal tract (UGIT) over a 6-year duration. Details of the lesions excised were as follows: median size was 20 mm, morphologically 20 (68.6%) were flat/depressed and 6 (17.1%) were submucosal, and histologically 27 (77.1%) were neoplastic. The median duration of ESD procedures was 105 minutes, with an en-bloc resection rate of 91.4%. There was 1 (2.9%) case of delayed bleeding, but no perforation nor mortality in any of the cases. The recurrence rate after ESD was 5.7%. A prolonged ESD duration was influenced by a larger size of lesion (25 mm, p = 0.02) but not by factors related to the training experience of endoscopists. Conclusions. ESD in the UGIT is feasible and safe in low volume centers in Asia.

Abstract
BACKGROUND The clinicopathological features and optimum treatment of esophageal neuroendocrine carcinoma (NEC) are hardly known due to its rarity. Therefore, we conducted a retrospective study to analyze the clinical characteristics and prognosis of patients with surgically resected esophageal NEC. METHODS We collected clinicopathological data on consecutive limited disease stage esophageal NEC patients who underwent esophagectomy with regional lymphadenectomy in West China Hospital from January 2007 to December 2013. RESULTS A total of forty-nine patients were analyzed retrospectively. The mean age of the patients was 58.4±8.2 years with male predominance. Fifty-five percent of the esophageal NEC were located in the middle thoracic esophagus. Histologically, 28 (57.1%) patients were found to be small cell NECs. Fifty-one percent of the patients were found to have lymph node metastasis. According to the 2009 American Joint Committee on Cancer (AJCC) staging system for esophageal squamous cell carcinoma, 9 patients were at stage I, 21 patients stage II, and 19 patients stage III. Twenty-six patients (53.1%) received adjuvant therapy. After a median follow-up of 44.8 months [95% confidence interval (CI), 35.2-50.4 months], the median survival time of the patients was 22.4 months (95% CI, 14.0-30.8 months). The 1-year and 3-year survival rates for the whole cohort patients were 74.9% and 35.3%, respectively. In univariate analysis, TNM staging, lymph node metastasis and adjutant therapy significantly influenced survival time. In multivariate analysis, TNM staging was the only independent prognostic factor. CONCLUSIONS Esophageal NEC has a poor prognosis. The 2009 AJCC TNM staging system for esophageal squamous cell carcinoma may also fit for esophageal NEC. Surgery combined with adjuvant therapy may be a good option for treating limited disease stage esophageal NEC. Further prospective studies defining the optimum therapeutic regimen for esophageal NEC are needed.

Abstract
BACKGROUND Treatment for type 1 gastric carcinoid (T1GC) includes esophagogastroduodenoscopy (EGD), polypectomy, and antrectomy, but few studies compare outcomes. This study assessed risk-benefit ratio to determine the most effective treatment for T1GC. METHODS A retrospective review of 52 T1GC patients (ages 30 to 88 years; 77% female) presenting to Mount Sinai Medical Center between 2004 and 2012 was conducted. Patient demographics, procedures, and outcomes were reviewed, and patient satisfaction was assessed using a phone-administered validated questionnaire. Data were analyzed using SPSS version 20 software. RESULTS Average EGDs needed per follow-up year was significantly lower for antrectomy than polypectomy or EGD surveillance (.395 vs 1.038 vs 1.380, P = .002). Antrectomy patients exhibited decreased recurrence risk than polypectomy patients (11% vs 44%, P = .049), despite longer follow-up time (6.10 vs 4.39 years, P = .023). CONCLUSIONS Antrectomy treats T1GC with lower recurrence risk and less postintervention monitoring, whereas allowing patients to avoid the discomfort of repeated EGD surveillance and anxiety over a lingering condition.

Abstract
BACKGROUND Optimal management and treatment of type-1 gastric carcinoids is under debate. AIMS This prospective study evaluates the outcome of patients with recurrent type-1 gastric carcinoids treated with somatostatin analogues. METHODS From 2000 to 2013, among a population of 107 chronic atrophic gastritis patients, 25 (20% males, median age 62 years) developed type-1 gastric carcinoids and underwent regular clinical and endoscopic follow-up (median 77 months, range 6-165) after the initial treatment. Those patients showing recurrent disease were treated with somatostatin analogues until carcinoid disappearance. RESULTS 12/25 patients (33% males, median age 65 years) showed recurrent gastric carcinoids and were treated with somatostatin analogues for a median duration of 12 months. Median gastrin and chromogranin A levels, which were 802 pg/mL and 33 U/L, respectively, decreased to 299 pg/mL (p=0.002) and 15.6 U/L (p=0.001) at the end of the treatment. Gastric carcinoids disappeared after a median length of treatment of 12 months. After a median time of 19.5 months from somatostatin analogues discontinuation, 4/12 patients (25% males, median age 56 years) showed a further recurrence. A new cycle of treatment was performed successfully. CONCLUSIONS This study confirms that type-1 gastric carcinoids are a recurring disease and somatostatin analogues, administered on 12-month cycles, represent an effective treatment.

Abstract
OBJECTIVE Endoscopic resection (ER) of foregut neuroendocrine tumors (NETs) is increasingly performed instead of surgery. This study aimed to compare the long-term therapeutic outcomes of ER and surgical resection (SR) for foregut NETs. METHODS From 2002 to 2012, a total of 49 patients with histologically confirmed foregut NETs were treated by ER (n = 33) and SR (n = 16). The clinicopathological characteristics and therapeutic outcomes were evaluated. RESULTS Of the 33 patients who underwent ER [endoscopic mucosal resection (n = 26), endoscopic mucosal dissection (n = 7)], 32 were diagnosed as NET-G1 and NET-G2, and the other as neuroendocrine carcinoma (NEC). Of the 16 patients who underwent SR, 10 were diagnosed as NET-G1, 2 as NET-G2 and 4 as NEC. The median tumor size was significantly smaller in the ER group compared with the SR group (7 mm vs 19 mm, P = 0.001). In almost all patients treated with ER (32/33), NET invasion was limited to the mucosa and submucosa. Non-curative resections were observed in 24.2% of the patients in the ER group (8/33) and 25.0% in the SR group (4/16). No recurrence occurred in NET cases with positive resection margins by ER. However, all cases of non-curative resection with lymphatic invasion (one in the ER group and four in the SR group) developed liver metastasis during the follow-up despite complete resection, and all these five patients has histologically confirmed NECs. CONCLUSION NET patients treated by ER may have a good prognosis if the tumor size is small and histologically low grade without lymphatic invasion.

Abstract
BACKGROUND Gastric subepithelial tumors represent a diagnostic and therapeutic challenge, given their histologic heterogeneity and potential malignant behavior. OBJECTIVE The objective of this article is to evaluate the interest, efficiency and safety of endoscopic resection for subepithelial gastric lesions of size <20 mm. METHODS We conducted a single-center retrospective study in a tertiary care center. RESULTS A total of 33 lesions (10 malignant/23 benign lesions) were studied. Mean histological size was 14.5 mm. Nine EMR, 18 ESD and six hybrid resections were performed. A total of 93.9% lesions were resected in one piece. At six months' follow-up, complete and definitive resection was obtained in 96.7% of cases. A vertical resection was insufficient in four cases. One GIST needed a complementary surgical resection, one neuroendocrine tumor was successfully treated by a new ESD session and two pancreatic rests were not additionally treated given the benign character and the absence of residual tissue in endoscopic control after six months. There was only one severe adverse event (2.9%); one pneumoperitoneum with ESD, three bleeding with one ESD and two EMR, always treated conservatively or endoscopically. CONCLUSION Endoscopic resection is safe and should be the procedure of choice for both diagnosis and definitive resection of subepithelial gastric lesions of size under 20 mm.

Abstract
BACKGROUND Gastrinomas are one of the neuroendocrine tumors with potential distant metastasis. Most gastrinomas are originated from pancreas and duodenum, but those of gastric origin have been much less reported. The aim of the study is to compare gastrinomas of gastric and non-gastric origins. METHODS Four hundred twenty-four patients with neuroendocrine tumor by histological proof in Chang Gung Memorial Hospital, Linkou branch in the past 10 years were included. A total of 109 (25.7 %) cases were identified of upper gastrointestinal origins, of which 20 (18.3 %) were proven gastrinomas. The clinical characteristics were collected and analyzed retrospectively. RESULTS In our study, 21 tumors of the 20 cases were identified by pathologic proof, 11 (55 %) had resection or endoscopic mucosa resection, 9 of gastric origins, 9 of duodenal origins, 2 of pancreatic origins, and 1 of hepatic origins. One case had multiple lesions. Patients with gastric gastrinomas had older age, higher levels of gastrin, seemingly smaller tumor size (p = 0.024, 0.030, and 0.065, respectively), and usually lower grade in differentiation (p = 0.035). Though gastric gastrinomas had a high recurrent rate (80 %), the lymph node and liver involvement was less common. Gastrinomas with liver involvement/metastasis had a high mortality rate where 80 % died of liver dysfunction. CONCLUSIONS Gastrinomas originating from stomach had higher gastrin level and lower tumor grading and presented at older age. The long-term outcome was probably better than non-gastric origin because of lower grading and less lymph node and liver involvement.

Abstract
Gastric carcinoids (GCs) are classified as: type I, related to hypergastrinemia due to chronic atrophic gastritis (CAG), type II, associated with Zollinger-Ellison syndrome in multiple endocrine neoplasia type 1, and type III, which is normogastrinemic. The management of type-I gastric carcinoids (GC1s) is still debated, because of their relatively benign course. According to the European Neuroendocrine Tumor Society guidelines endoscopic resection is indicated whenever possible; however, it is not often feasible because of the presence of a multifocal disease, large lesions, submucosal invasion or, rarely, lymph node involvement. Therefore, somatostatin analogs (SSAs) have been proposed as treatment for GC1s in view of their antisecretive, antiproliferative and antiangiogenic effects. However, in view of the high cost of this therapy, its possible side effects and the relatively benign course of the disease, SSAs should be reserved to specific subsets of “high risk patients”, i.e., those patients with multifocal or recurrent GCs. Indeed, it is reasonable that, after the development of a gastric neuroendocrine neoplasm in patients with a chronic predisposing condition (such as CAG), other enterochromaffin-like cells can undergo neoplastic proliferation, being chronically stimulated by hypergastrinemia. Therefore, definite indications to SSAs treatment should be established in order to avoid the undertreatment or overtreatment of GCs.

Abstract
Submucosal gastrointestinal tumors represent a unique, diverse and challenging group of lesions found in modern medical practice. While management has traditionally been surgical, the development of advanced endoscopic techniques is challenging this approach. This review aims to investigate the role of endotherapy in treatment pathways, with a focus on carcinoid and gastrointestinal stromal tumors. In particular, we will discuss which lesions can be safely treated endoscopically, the evidence base behind such approaches and the limitations of the current evidence. The review will consider how these techniques may change the management of submucosal tumors in the future.

Abstract
A 32-year-old Japanese man presented with a gastric submucosal tumor. Esophagogastroduodenoscopy showed a sessile submucosal tumor measuring approximately 10 mm in diameter on the greater curvature of the gastric antrum. Endoscopic ultrasonography examination revealed a solid tumor with a diameter of 11.8 mm, which was located in the deep mucosal and submucosal layers. The internal echogenicity was homogenous and hypoechoic. Biopsy examinations were performed twice but were not diagnostic since only the intact mucosal layer was obtained. The patient was subsequently diagnosed with ectopic pancreas in the stomach by endoscopic submucosal dissection (ESD). This case underscores the usefulness of the ESD technique for the pathological diagnosis of gastric submucosal tumors.

Abstract
Objectives. Sessile nonampullary duodenal tumors (SNADTs) are relatively rare and endoscopic resection of these lesions is considered more challenging than in other parts of the gastrointestinal tract. The aim of this study was to evaluate the feasibility of endoscopic resection for SNADT. Methods. Medical records including endoscopic resection for SNADT from July 2002 to July 2013 from 5 centers affiliated to The Catholic University of Korea were reviewed retrospectively. Demographic features and clinical outcomes such as complete resection and complications were analyzed. Results. A total of 56 lesions from 54 patients were enrolled in this study. Forty-five lesions were resected by endoscopic mucosal resection (EMR), 6 lesions by endoscopic submucosal dissection (ESD), and 5 lesions by simple polypectomy. Histologic examination after endoscopic resection revealed adenocarcinoma in 2, low grade adenoma in 25, high grade adenoma in 11, and carcinoid tumor in 18 lesions. En bloc resection rates and histological complete resection rates were 78.6% (44/56) and 80.0% (28/35), respectively. Bleeding which required additional endoscopic intervention occurred in 1.8% (1/56) and perforation in 7.1% (4/56). There was no procedure-related mortality. Conclusions. Endoscopic resection techniques including ESD might be safe and effective modalities for the management of SNADT.

Abstract
BACKGROUND Gastric carcinoids (GCs) or neuroendocrine tumours (NETs) are increasingly identified at endoscopy, and account for 0.6-2% of all gastric polyps identified. The SEER database in the US has demonstrated a rising incidence of gastric NETs amongst all NETs; from 2.2% between 1950 and 1969 to 6.0% between 2000 and 2007. AIM To review the literature and assist clinicians in managing patients with GCs. METHODS A literature search was conducted through MEDLINE using search terms: gastric, carcinoid, neuroendocrine tumour, therapy, endoscopy, mucosal resection, submucosal dissection. Relevant articles were identified through manual review. The reference lists of these articles were reviewed to include further appropriate articles. RESULTS There are three types of GCs with important epidemiological, pathophysiological, histological and endoscopic differences that affect prognosis and management. Type 1 and 2 GCs develop in the context of hypergastrinaemia that originates from achlorhydria in atrophic gastritis and a gastrinoma, respectively. Type 3 GCs occur sporadically and independent of gastrin. The histological type, grade and Ki67 index are used to determine prognosis and direct clinical management. Type 1 GCs >1 cm in size and type 2 GCs should be assessed for invasion beyond the submucosa with EUS prior to endoscopic resection with EMR or ESD. Type 3 GCs should be managed as per recommendations for gastric adenocarcinoma. The treatment of advanced disease is multimodal. CONCLUSIONS Patients with gastric carcinoids should be discussed in a specialist neuroendocrine tumour multidisciplinary meeting to ensure all treatment options are explored in localised and advanced disease. Areas of controversy exist that need further research.

The efficacy of endoscopic submucosal dissection of type I gastric carcinoid tumors compared with conventional endoscopic mucosal resection. Gastroenterol Res Pract 2014; 2014:253860. [PMID: 24693280 PMCID: PMC3947882 DOI: 10.1155/2014/253860] [Citation(s) in RCA: 35] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2013] [Accepted: 01/09/2014] [Indexed: 12/13/2022] Open
Abstract
Background and Aims. Conventional endoscopic submucosal resection (EMR) of carcinoid tumors often involves the resection margin, which necessitates further intervention. Endoscopic submucosal dissection (ESD) is widely accepted for removing carcinoid tumors. We aimed to evaluate the clinical usefulness of ESD with that of EMR for resection of type I gastric carcinoid tumors. Patients and Methods. The study enrolled 62 patients (37 males, 25 females; median age, 50 years; range, 40-68 years) who were treated with EMR or ESD at three hospitals; the study group had 87 type I gastric carcinoid tumors with an estimated size of ≤10 mm. The complete resection rate and the complications associated with these two procedures were analyzed. Results. The overall ESD complete resection rate was higher than that of the EMR rate (94.9% versus 83.3%, P value = 0.174). A statistically lower vertical margin involvement rate was achieved when ESD was performed compared to when EMR was performed (2.6% versus 16.7%, P value = 0.038). The complication rate was not significantly different between the two groups. Conclusions. ESD showed a higher complete resection rate, particularly for the vertical margin, with a similar complication rate. We mildly recommend ESD rather than EMR for removing type I gastric carcinoid tumors.
