Abstract
OBJECTIVES Extension of adenocarcinoma of the esophagogastric junction under the squamous epithelium may lead to errors when determining lateral margins. However, the characteristics of subsquamous extension are unclear. Herein, we evaluated the prevalence and characteristics of subsquamous extension of adenocarcinoma of the esophagogastric junction and the diagnostic performance of endoscopy for this condition. METHODS Eighty-nine consecutive patients with superficial adenocarcinoma of the esophagogastric junction who underwent endoscopic or surgical resection at a tertiary cancer center between January 2010 and December 2017 were retrospectively evaluated. Endoscopic subsquamous extension was defined as a submucosal tumor-like elevation covered by squamous epithelium and/or a brownish area with abnormal microvessels on the squamous epithelium observed using narrow-band imaging. The diagnostic performance of endoscopy for subsquamous extension was evaluated using histological subsquamous extension as gold standard. RESULTS Thirty-nine patients (44%) had histological subsquamous extension. Proton pump inhibitor use was significantly associated with histological subsquamous extension [odds ratio: 4.65; 95% confidence interval (CI): 1.77-12.2]. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of endoscopic subsquamous extension were 56% (95% CI: 40-72%), 96% (86-99%), 92% (73-99%), 74% (62-84%) and 79% (69-87%), respectively. The median length difference between histological and endoscopic subsquamous extension was 2 mm (range: -6 to 9 mm). CONCLUSIONS The sensitivity of endoscopic diagnosis of subsquamous extension was unsatisfactory. The endoscopic length of subsquamous extension tended to be underestimated. An oral safety margin of one centimeter is reasonable during endoscopic resection of adenocarcinoma of the esophagogastric junction.IMPACT STATEMENT This study will contribute significantly to the literature because this is the first study to determine the difference between the lengths of subsquamous extension detected endoscopically and histologically. This study determines the prevalence of subsquamous extension and identifies characteristics associated with subsquamous extension. An understanding of the risk of subsquamous extension is important when choosing a treatment strategy and planning the resection margins in patients with adenocarcinoma of the esophagogastric junction. This study provides patients with subsquamous extension characteristics and suggests a method for accurately diagnosing this condition.

Abstract
Purpose Most studies have investigated the differences in postgastrectomy quality of life (QOL) based on the surgical procedure or reconstruction method adopted; only a few studies have compared QOL based on tumor location. This large-scale study aims to investigate the differences in QOL between patients with esophagogastric junction cancer (EGJC) and those with upper third gastric cancer (UGC) undergoing the same gastrectomy procedure to evaluate the impact of tumor location on postoperative QOL. Methods The Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45) questionnaire was distributed in 70 institutions to 2,364 patients who underwent gastrectomy for EGJC or UGC. A total of 1,909 patients were eligible for the study, and 1,744 patients who underwent total gastrectomy (TG) or proximal gastrectomy (PG) were selected for the final analysis. These patients were divided into EGJC and UGC groups; thereafter, the PGSAS-45 main outcome measures (MOMs) were compared between the two groups for each type of gastrectomy. Results Among the post-TG patients, only one MOM was significantly better in the UGC group than in the EGJC group. Conversely, among the post-PG patients, postoperative QOL was significantly better in 6 out of 19 MOMs in the UGC group than in the EGJC group. Conclusions Tumor location had a minimal effect on the postoperative QOL of post-TG patients, whereas among post-PG patients, there were definite differences in postoperative QOL between the two groups. It seems reasonable to conservatively estimate the benefits of PG in patients with EGJC compared to those in patients with UGC.

Abstract
Background Endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) are used to remove esophagogastric junction (EGJ) neoplasm. This study aimed to compare feasibility, safety, and effectiveness between ESD and EMR to help endoscopists choose treatment methods. Methods A total of 130 patients with EGJ neoplasm underwent endoscopic resection, including 52 patients with EMR and 78 patients with ESD. Cap-assisted EMR (EMRC) was performed with typical sequences. Larger lesions required removal in multiple pieces (i.e., piecemeal EMR). The ESD procedures were included that marking the periphery of the lesion, submucosa injected, circumferentially cutting and submucosal dissection. Resection time, adverse events, en bloc resection rate, R0 resection rate and recurrence rate were compared between the two groups. Results There were no significant differences in demographic characteristics or histopathological features between the two groups. Resection time was longer in the ESD group than in the EMR group (64.4±33.9 vs. 22.1±8.0 minutes; P<0.01). Adverse events were more common in the ESD group than in the EMR group (16.7% vs. 3.8%; P=0.03), including bleeding (7.7% vs. 3.8%), perforation (5.1% vs. 0%) and stenosis (5.1% vs. 0%). The en bloc resection rate and R0 resection rate were much higher in the ESD group than in the EMR group (98.7% and 92.3% vs. 23.1% and 23.1%, respectively; P<0.01). The 5-year overall survival rate and disease-free survival rate were 100% vs. 92.0% and 100% vs. 90.1% between the ESD and EMR groups, respectively (P=0.01 and P=0.01). The 5-year cancer-specific survival rate was 100% vs. 96.0% between the ESD and EMR groups (P=0.08). The recurrence rate was lower in the ESD group than in the EMR group (0% vs. 9.6%; P=0.01). Conclusions ESD is an acceptable first-line endoscopic treatment for type II EGJ neoplasm, however, it is time-consuming and has a higher rate of adverse events. Furthermore, EMR is a safe and alternative technique, particularly when EMR could achieve en bloc resection.

Abstract
Background It is still difficult to detect and diagnose early adenocarcinoma of the esophagogastric junction (EGJ) using conventional endoscopy or image-enhanced endoscopy. A glutamylprolyl hydroxymethyl rhodamine green (EP-HMRG) fluorescent probe that can be enzymatically activated to become fluorescent after the cleavage of a dipeptidyl peptidase (DPP)-IV-specific sequence has been developed and is reported to be useful for the detection of squamous cell carcinoma of the head and neck, and esophagus; however, there is a lack of studies that focuses on detecting EGJ adenocarcinoma by fluorescence molecular imaging. Therefore, we investigated the visualization of early EGJ adenocarcinoma by applying EP-HMRG and using clinical samples resected by endoscopic submucosal dissection (ESD). Methods Fluorescence imaging with EP-HMRG was performed in 21 clinical samples resected by ESD, and the fluorescence intensity of the tumor and non-tumor regions of interest was prospectively measured. Immunohistochemistry was also performed to determine the expression of DPP-IV. Results Fluorescence imaging of the clinical samples showed that the tumor lesions were visualized within a few minutes after the application of EP-HMRG, with a sensitivity, specificity, and accuracy of 85.7, 85.7, and 85.7%, respectively. However, tumors with a background of intestinal metaplasia did not have a sufficient contrast-to-background ratio since complete intestinal metaplasia also expresses DPP-IV. Immunohistochemistry measurements revealed that all fluorescent tumor lesions expressed DPP-IV. Conclusions Fluorescence imaging with EP-HMRG could be useful for the detection of early EGJ adenocarcinoma lesions that do not have a background of intestinal metaplasia.

Abstract
Background We present the first description of en bloc endoscopic submucosal dissection (ESD) for total circumferential Barrett’s adenocarcinoma, predominantly of the long-segment Barrett’s esophagus (LSBE), with a 2-year follow-up and management strategies for esophageal stricture prevention. Case presentation A 59-year-old man was diagnosed with LSBE and Barrett’s adenocarcinoma by esophagogastroduodenoscopy (EGD). A 55-mm-long circumferential tumor was completely resected by ESD. Histopathology revealed a well-differentiated adenocarcinoma within the LSBE superficial muscularis mucosa. For post-ESD stricture prevention, the patient underwent an endoscopic triamcinolone injection administration, oral prednisolone administration, and preemptive endoscopic balloon dilatation. Two years later, there is no evidence of esophageal stricture or recurrence. Conclusions ESD appears to be a safe, effective option for total circumferential Barrett’s adenocarcinoma in LSBE.

Abstract
BACKGROUND AND AIM The incidence of esophageal adenocarcinoma (EAC) in cases with long-segment Barrett's esophagus (BE) has not been investigated in Japan. The aim of this study is to investigate the incidence of EAC in Japanese cases with long-segment BE prospectively. METHODS This is a multicenter prospective cohort study investigating the incidence rate of EAC in patients with BE with a length of at least 3 cm. Study subjects received index esophagogastroduodenoscopy at the time of enrollment, and they were instructed to undergo yearly follow-up esophagogastroduodenoscopy. Patients in whom EAC was diagnosed in the endoscopic examinations underwent subsequent treatment, and their prognosis was observed. RESULTS Of 215 enrolled patients, six (2.8%) were initially diagnosed with EAC at the enrollment. Among the remaining 209 patients, 132 received at least one follow-up esophagogastroduodenoscopy. In this follow-up, three EACs developed in 251 observed patient-years (incidence rate: 1.2% per year). Most of the EACs detected at the initial endoscopic examination (5/6, 83%) were already at advanced stages. Meanwhile, all the three lesions detected in the follow-up esophagogastroduodenoscopies were identified as early cancers and subjected to curative resection. CONCLUSIONS The incidence rate of EAC in Japanese cases with long-segment BE was calculated to be 1.2% in a year.

Abstract
BACKGROUND AND STUDY AIMS Barrett's esophagus (BE) - associated neoplasia can be treated endoscopically, but accurate assessment before intervention is challenging. This study aimed to investigate the role of confocal laser endomicroscopy (CLE) as an adjunct in the endoscopic treatment of BE-associated neoplasia by assessing lateral tumor and subsquamous tumor (SST) extension. PATIENTS AND METHODS In the context of a prospective, single-arm pilot clinical trial, patients referred for endoscopic resection of BE-associated neoplasia (high grade dysplasia and esophageal adenocarcinoma) underwent high definition, white light endoscopy with narrow-band imaging (NBI). Then, CLE mapping of suspected neoplastic lesions was performed by another endoscopist, partially blinded to the previous findings, before the patients underwent endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD), depending on lesion size and anticipated histology. RESULTS In 7 of 38 patients (18 %), CLE revealed additional neoplastic tissue compared with prior white light endoscopy and NBI: 2 concomitant lesions, 2 cases of lateral tumor extension within the Barrett's epithelium, and 3 cases of previously undetected SST extension. Overall, en bloc resection (tumor-free lateral margin) was achieved in 28 of 34 neoplastic lesions (82 %), and complete resection (tumor-free lateral and basal margins) in 21 of 34 neoplastic lesions (62 %). CONCLUSIONS CLE-assisted endoscopic resection of BE-associated neoplasia was safe and effective in this study, as proved by a high additional diagnostic yield of CLE (including visualization of occult SST extension) and a favorable rate of en bloc resection. The clinical value of CLE for assisting endoscopic therapy of BE-associated neoplasia deserves further evaluation in randomized controlled trials.

Current status of endoscopic diagnosis and treatment of superficial Barrett's adenocarcinoma in Asia-Pacific region. Dig Endosc 2013; 25 Suppl 2:146-50.

Abstract
The incidence of Barrett's adenocarcinoma has increased dramatically over the past few decades in most Western countries. While Barrett's esophagus is uncommon and adenocarcinoma is still rare in Asian populations, several Asian studies have indicated that the prevalence of esophageal adenocarcinoma is gradually increasing. Therefore, in order to determine the best way to treat superficial Barrett's adenocarcinoma, 12 expert endoscopists and a pathologist from the Asia-Pacific region conducted a session entitled 'The current status of endoscopic diagnosis and treatment of superficial Barrett's adenocarcinoma'. After three keynote lectures, three Japanese panels presented cases of superficial Barrett's adenocarcinomas diagnosed by image-enhanced endoscopy (IEE). We then confirmed the results of a questionnaire on the diagnosis and treatment of superficial Barrett's adenocarcinomas. Finally, a panel introduced an Asia-Pacific international study on simplified narrow-band imaging (NBI) classification of Barrett's esophagus and neoplasias. After a discussion, we proposed consensus statements on endoscopic diagnosis and treatment of superficial Barrett's adenocarcinoma as follows. Representative characteristics by conventional white light endoscopy are a reddish area or a lesion located on the anterior to right side wall. IEE may be useful for characterizing the tumor and diagnosing lateral tumor extension. Superficial Barrett's adenocarcinoma adjacent to the squamocolumnar junction is sometimes associated with subsquamous tumor extension. IEE may be useful to detect the subsquamous tumor extension especially when using NBI or an acetic acid-spraying method. Endoscopic mucosal resection or endoscopic submucosal dissection for mucosal carcinomas could provide excellent prognosis.
