Abstract
BACKGROUND AND AIMS Data are limited on the role of endoscopic submucosal dissection (ESD) as a potential diagnostic and staging tool in Barrett's esophagus (BE) neoplasia. We aimed to evaluate the frequency and factors associated with change of histologic diagnosis by ESD compared with pre-ESD histology. METHODS This was a multicenter, prospective cohort study of patients who underwent ESD for BE visible neoplasia. A change in histologic diagnosis was defined as "upstaged" or "downstaged" if the ESD specimen had a higher or lower degree, respectively, of dysplasia or neoplasia when compared with pre-ESD specimens. RESULTS Two hundred five patients (median age, 69 years; 81% men) with BE visible neoplasia underwent ESD from 2016 to 2021. Baseline histology was obtained using forceps (n = 182) or EMR (n = 23). ESD changed the histologic diagnosis in 55.1% of cases (113/205), of which 68.1% were upstaged and 31.9% downstaged. The frequency of change in diagnosis after ESD was similar whether baseline histology was obtained using forceps (55.5%) or EMR (52.2%) (P = .83). In aggregate, 23.9% of cases (49/205) were upstaged to invasive cancer on ESD histopathology. On multivariate analysis, lesions in the distal esophagus and gastroesophageal junction (odds ratio, 2.1; 95 confidence interval, 1.1-3.9; P = .02) and prior radiofrequency ablation (odds ratio, 2.5; 95% confidence interval, 1.2-5.5; P = .02) were predictors of change in histologic diagnosis. CONCLUSIONS ESD led to a change of diagnosis in more than half of patients with BE visible neoplasia. Selective ESD can serve as a potential diagnostic and staging tool, particularly in those with suspected invasive disease. (Clinical trial registration number: NCT02989818.).

Abstract
Modern management of Barrett's oesophagus and related neoplasia essentially focuses upon surveillance to detect early low-risk neoplastic lesions and offering organ-preserving advanced endoscopic therapies, while traditional surgical treatments of oesophagectomy and lymph node clearance with or without chemoradiation are preserved only for high-risk and advanced carcinomas. With this evolution towards figless invasive therapy, the choice of therapy hinges upon the pathological assessment for risk stratifying patients into those with low risk for nodal metastasis who can continue with less invasive endoscopic therapies and others with high risk for nodal metastasis for which surgery or other forms of treatment are indicated. Detection and confirmation of neoplasia in the first instance depends upon endoscopic and pathological assessment. Endoscopic examination and biopsy sampling should be performed according to the recommended protocols, and endoscopic biopsy interpretation should be performed applying standard criteria using appropriate ancillary studies by histopathologists experienced in the pathology of Barrett's disease. Endoscopic resections (ERs) are both diagnostic and curative and should be performed by clinicians who are skilled with advanced endoscopic techniques. Proper preparation and handling of ERs are essential to assess histological parameters that dictate the curative nature of the procedure. Those parameters are adequacy of resection and risk of lymph node metastasis. The risk of lymph node metastasis is determined by depth invasion and presence of poor differentiation and lymphovascular invasion. Those adenocarcinomas with invasion up to muscularis mucosae (pT1a) and those with superficial submucosal invasion (pT1b) up to 500 µ with no poor differentiation and lymphovascular invasion and negative margins may be considered cured by endoscopic resections.

Abstract
Endoscopic resection (ER) allows optimal staging with potential cure of early-stage luminal malignancies while maintaining organ preservation. ER and surgery are non-competing but complementary therapeutic options. In addition, histological examination of ER specimens can either confirm or refine the pre-procedure diagnosis. ER is used for the treatment of Barrett's related early carcinomas and dysplasias, early-esophageal squamous cell carcinomas and dysplasias, early gastric carcinomas and dysplasia, as well as low-risk submucosal invasive carcinomas (LR-SMIC) and, large laterally spreading adenomas of the colon. For invasive lesions, histological risk factors predict risk of lymph node metastasis and residual disease at the ER site. Important pathological risk factors predictive of lymph node metastasis are depth of tumor invasion, poor differentiation, and lymphovascular invasion. Complete resection with negative margins is critical to avoid local recurrences. For non-invasive lesions, complete resection is curative. Therefore, a systematic approach for handling and assessing ER specimens is recommended to evaluate all above key prognostic features appropriately. Correct handling starts with pinning the specimen before fixation, meticulous macroscopic assessment with orientation of appropriate margins, systematic sectioning, and microscopic assessment of the entire specimen. Microscopic examination should be thorough for accurate assessment of all pathological risk factors and margin assessment. Site-specific issues such as duplication of muscularis mucosa of the esophagus, challenges of assessing ampullectomy specimens and site-specific differences of staging of early carcinomas throughout the gastrointestinal tract (GI) tract should be given special consideration. Finally, a standard, comprehensive pathology report that allows optimal staging with potential cure of early-stage malignancies or better stratification and guidance for additional treatment should be provided.

Abstract
BACKGROUND Early gastro-esophageal cancer is staged as m1 to m3 depending on the infiltration of the anatomical layers of the mucosa or, analogously, as sm1 to sm3 depending on the depth of infiltration into the submucosa. The risk of lymph node metastases is low in mucosal carcinoma but increases with the depth of infiltration into the submucosa. METHODS This review is based on pertinent publications retrieved by a selective search in MEDLINE, PubMed, the Cochrane Library, and the International Standard Randomised Controlled Trial Number (ISRCTN) registry. RESULTS New technologies such as narrow-band imaging have improved the endo- scopic diagnosis and staging of early gastro-esophageal cancer. The development of endoscopic submucosal dissection has led to a higher R0 resection rate, a lower risk of recurrence, and an increase in the number of endoscopic resections that are performed with curative intent. In squamous-cell carcinoma of the esophagus, surgical oncological esophagectomy is indicated if the cancer infiltrates into the third mucosal layer (T1a, m3) or deeper. In esophageal adenocarcinoma, the prevalence of lymph node metastases is low if the cancer is restricted to the mucosa and in- creases only when the submucosa is infiltrated. In the current German S3 guideline, endoscopic resection is recommended for intramucosal adenocarcinoma as long as there are no further histopathological risk factors. Lymph node metastasis in gastric carcinoma begins in the deep mucosal infiltration stage (m3). If certain special con- ditions ("extended criteria") are met, carcinoma expanding into the first submucosal layer (sm1) can be removed endoscopically. All further stages must be treated with total or subtotal gastrectomy with systematic D2 lymphadenectomy. CONCLUSION Borderline cases between endoscopic and surgical resection of early carcinoma of the esophagus or stomach must be managed with an interdisciplinary treatment algorithm. If there is a risk of lymph node metastasis, surgical oncological resection is indicated. Such resections of gastroesophageal cancer in the locally advanced stage should always be part of a multimodal treatment approach.

Abstract
Esophageal adenocarcinoma carries a very poor prognosis. For this reason, it is critical to have cost-effective surveillance and prevention strategies and early and accurate diagnosis, as well as evidence-based treatment guidelines. Barrett’s esophagus is the most important precursor lesion for esophageal adenocarcinoma, which follows a defined metaplasia–dysplasia–carcinoma sequence. Accurate recognition of dysplasia in Barrett’s esophagus is crucial due to its pivotal prognostic value. For early-stage esophageal adenocarcinoma, depth of submucosal invasion is a key prognostic factor. Our systematic review of all published data demonstrates a “rule of doubling” for the frequency of lymph node metastases: tumor invasion into each progressively deeper third of submucosal layer corresponds with a twofold increase in the risk of nodal metastases (9.9% in the superficial third of submucosa (sm1) group, 22.0% in the middle third of submucosa (sm2) group, and 40.7% in deep third of submucosa (sm3) group). Other important risk factors include lymphovascular invasion, tumor differentiation, and the recently reported tumor budding. In this review, we provide a concise update on the histopathological features, ancillary studies, molecular signatures, and surveillance/management guidelines along the natural history from Barrett’s esophagus to early stage invasive adenocarcinoma for practicing pathologists.

Abstract
AIM To test the validity of tumour thickness measurement in distinguishing between the different infiltration depths, especially when the duplication of muscularis mucosae cannot be demarcated clearly.
METHODS We re-evaluated 100 completely embedded Barrett’s adenocarcinomas regarding m-classification, maximum tumour thickness, and muscularis mucosae duplication. For validation, smoothelin staining was performed on a subset of cases.
RESULTS The m1-, m2- and m3-classified adenocarcinomas showed a significant lower tumour thickness compared to the m4- and sm1-classified lesions (P < 0.001). Smoothelin staining determined a clear muscularis mucosae duplication in 64% of the tested samples and enabled the differentiation of the two layers in diffuse and merged splits.
CONCLUSION Tumour thickness in early oesophageal adenocarcinoma significantly correlates with the depth of infiltration and demonstrates its worth as an accurate pT classification in non-polypoid lesions. We created a new algorithm, which combines histomorphology with morphometric analyses. It is noteworthy that it facilitates the assessment of mucosal vs submucosal infiltration depth. The smoothelin staining strengthened our results of the tumour thickness evaluation and can be used in cases of doubt.

Abstract
The rate of lymph-node (LN) metastasis in early adenocarcinoma (EAC) of the esophagus with mid to deep submucosal invasion (pT1b sm2/3) has not yet been precisely defined. The aim of the this study was to evaluate the rate of LN metastasis in pT1b sm2/3 EAC depending on macroscopic and histological risk patterns to find out whether there may also be options for endoscopic therapy as in cancers limited to the mucosa and the upper third of the submucosa. A total of 1.718 pt with suspicion of EAC were referred for endoscopic treatment (ET) to the Dept. of Internal Medicine II at HSK Wiesbaden 1996-2010. In 230/1.718 pt, the suspicion (endoscopic ultrasound, EUS) or definitive diagnosis of pT1b EAC (ER/surgery) was made. Of these, 38 pt had sm2 lesions, and 69 sm3. Rate of LN metastasis was analyzed depending on risk patterns: histologically low-risk (hisLR): G1-2, L0, V0; histologically high-risk (hisHR): ≥1 criterion not fulfilled; macroscopically low-risk (macLR): gross tumor type I-II, tumor size ≤2 cm; macroscopically high-risk (macHR): ≥1 criterion not fulfilled; combined low-risk (combLR): hisLR+macLR; combined high-risk (combHR): at least 1 risk factor. LN rate was only evaluated in pt who had proven maximum invasion depth of sm2/sm3, and who in case of ET had a follow-up (FU) by EUS of at least 24 months. 23/38 pt with pT1b sm2 lesions and 39/69 pt with sm3 lesions fulfilled our inclusion criteria. In the pT1b sm2 group, rate of LN metastasis in the hisLR, hisHR, combLR, and combHR groups were 8.3% (1/12), 36.3% (4/11), 0% (0/5), and 27.8% (5/18). In the pT1b sm3 group, rate of LN metastasis in the hisLR, hisHR, combLR and combHR groups were 28.6% (2/7), 37.5% (12/32), 25% (1/4), and 37.1% (13/35). 30-day mortality of surgery was 1.7% (1/58 pt). In EAC with pT1b sm2/3 invasion, the frequency of LN metastasis depends on macroscopic and histological risk patterns. Surgery remains the standard treatment, because the rate of LN metastasis appears to be higher than the mortality risk of surgery. Whether a highly selected group of pT1b sm2 patients with a favourable risk pattern may be candidates for endoscopic therapy cannot be decided until the results of larger case volumes are available.

Abstract
In the current S2k guideline for gastroesophageal reflux disease and the new S3 guideline for esophageal cancer, histopathological evaluation of Barrett's esophagus has been revised and supplemented. The histological diagnosis of Barrett's esophagus still requires the proof of a specialized intestinal metaplastic epithelium (columnar epithelium with goblet cells). Barrett mucosa must be classified as negative, unclear/doubtful, and positive concerning the intraepithelial neoplasia (IEN)/dysplasia according to the current WHO guideline. Each IEN should be confirmed by an external second opinion due to poor interobserver variability. The pathological classification is of decisive importance here, since the recommended monitoring intervals are based solely on the ground of proved IEN. Risk factors in endoscopic resection specimens such as depth of infiltration (m1-m4; sm1-sm3; distance in µm); angioinvasion (L, V); grading and lateral/basal resection margin have to be reported. In surgical specimens, the reference of the tumor center to the gastroesophageal junction and in the neoadjuvant situation the tumor regression should be documented.

Abstract
Endoscopic resection (ER) is considered the therapy of choice for intraepithelial neoplasia associated with visible lesions and T1a adenocarcinoma. Pathologists are bound to encounter specimens collected via these techniques more frequently in their practice. A standardised protocol for handling, grossing, and assessing ER specimens should be adopted to ensure that all prognostic information and characteristics influencing treatment are included in reports (see Supplementary Video Abstract, http://links.lww.com/PAT/A22). The entire specimen should be appropriately oriented, processed and assessed. An ER specimen will commonly show intraepithelial neoplasia or invasive carcinoma. There are essential features that should be recorded if invasive carcinoma is found as they dictate further management and follow-up. These features are the margin status, depth of invasion, degree of differentiation and presence or absence of lymphovascular invasion. Important features such as duplication of muscularis mucosae should be recognised to avoid misinterpretation of depth of invasion. Key diagnostic and prognostic elements that are essential for optimal clinical decisions have been included in the reporting format proposed by the Structured Pathology Reporting committee of the Royal College of Pathologists of Australasia (RCPA).

Abstract
BACKGROUND AND STUDY AIMS Endoscopic submucosal dissection (ESD) carries significant advantages over endoscopic mucosal resection. As such, ESD is an established therapy for esophageal squamous cell carcinoma but there are only limited data on ESD as therapy for Barrett's esophagus (BE). Thus, we prospectively evaluated the outcomes of ESD in patients with BE with high-grade dysplasia (HGD) and early esophageal adenocarcinoma (EAC) performed in a Western center. PATIENTS AND METHODS This is a prospective cohort study. Indications for ESD included: (1) early EAC defined as lesions with intramucosal cancer or superficial submucosal invasion; (2) early EAC with positive lateral margin after EMR; and (3) nodularity with HGD that could not be removed en-bloc with EMR Results: From October 2013 to July 2015, 36 consecutive patients (median age 69, 32 males) underwent ESD at our center. Median procedure time was 88 minutes, with median maximal diameter of resected specimens of 49 mm. En-bloc, R0, and curative resection rates were 100 %, 81 %, and 69 %, respectively. Intramucosal EAC was found in 13 patients (36 %), and submucosal invasion in 13 patients (36 %). In 59 % of the cases, there was discrepancy in the pre- and post-ESD histopathologic diagnosis. Adverse events occurred in 8 patients (22 %), including one episode of bleeding treated with endoscopy and seven esophageal strictures, which were successfully managed with dilations. CONCLUSIONS ESD for BE with HGD/early EAC is feasible and safe with resulting very high en-bloc and R0 resection rates. ESD provided for more accurate pathologic evaluation and significant discrepancy between the pre- and post-ESD histopathological diagnosis was noted.

Abstract
OBJECTIVE Evaluate the incidence of metachronous visible lesions (VLs) in patients referred for radiofrequency ablation (RFA) for early Barrett's neoplasia. DESIGN This study was conducted as part of the service evaluation audit. SETTING Tertiary referral centre. PATIENTS All patients with dysplastic Barrett's oesophagus referred for RFA were included for analysis. White light high-resolution endoscopy (HRE), autofluorescence imaging and narrow band imaging were sequentially performed. Endoscopic mucosal resection (EMR) was performed for all VL. Three to six months after EMR, all patients underwent initial RFA and then repeat RFA procedures at three monthly intervals. INTERVENTIONS All endoscopy reports and final staging by EMR/surgery were evaluated and included for analysis. RESULTS Fifty patients were analysed; median age 73 years, 84% men. 38/50 patients (76%) had a previous EMR due to the presence of VL before referred for ablation; twelve patients had no previous treatment. In total, 151 ablation procedures were performed, median per patient 2.68. Twenty metachronous VL were identified in 14 patients before the first ablation or during the RFA protocol; incidence was 28%. All metachronous lesions were successfully resected by EMR. Upstaging after rescue EMR compared with the initial histology was observed in four patients (28%). CONCLUSIONS In total, 28% of patients enrolled in the RFA programme were diagnosed to have metachronous lesions. This high-incidence rate highlights the importance of a meticulous examination to identify and resect any VL before every ablation session. RFA treatment for early Barrett's neoplasia should be performed in tertiary referral centres with HRE and EMR facilities and expertise.

Abstract
OBJECTIVE To define prognostic risk factors in patients with early adenocarcinomas of the esophagus (eACEs) who were treated by esophagectomy. BACKGROUND Although endoscopic resection (ER) is more accepted for eACEs limited to the mucosa, the reported prevalence of lymph node metastases once the tumor infiltrates the submucosa seems to necessitate surgery in these cases. METHODS We analyzed the results of 168 patients who had an esophageal resection because of an eACE. On the basis of specimen histologies and clinical follow-up (median, 64 months), we investigated the influence of lymph node metastases (N+), tumor infiltration depth, tumor differentiation (G1-3), and lymphatic or venous infiltration (L+ or V+) on overall and tumor-specific survival and recurrence rates. RESULTS The 5-year survival rate was 79%. Lymph node infiltration was the only prognostic factor for the overall survival [hazard ratio (HR), 2.856; 1.314-6.207; P = 0.008], tumor-specific survival (HR, 8.336; 2.734-25.418; P < 0.001), and tumor recurrence (HR, 8.031; 3.041-21.206; P < 0.001) that was consistently present in all multivariate hazard Cox regression analyses. A total of 47% of the patients who had an N+ status developed tumor recurrences compared with 5.2% of those who had no lymph node involvement (P = <0.001). We found a significant correlation between N+ status and increasing depth of tumor infiltration (P = 0.004), lymphatic vessel infiltration (P = 0.002), tumor differentiation (G1 + G2 vs G3; P = 0.014) and vascular infiltration (P = 0.01). CONCLUSIONS Lymph node status is the only independent risk factor for survival and recurrence rates. Tumor infiltration depth correlates with the rate of the lymph node metastases, but a clear watershed between deep mucosal and submucosal infiltration does not exist. As a consequence, careful staging procedures, including diagnostic ER, are mandatory to determine which patients can be treated by ER and which require an esophagectomy.

Abstract
The definition of Barrett esophagus is currently under discussion. It is now suggested that a distal esophagus coated with cylinder epithelium with cardia-fundus mucosa should also be classified as Barrett esophagus because the risk of cancer is significantly increased even without histological evidence of intestinal metaplasia with goblet cells. The results of recent epidemiological investigations imply that the cancer risk of cylinder cell metaplasia and low grade intraepithelial neoplasia in Barrett esophagus has previously been overestimated. The histological detection of dysplasia still remains the best biomarker for estimation of the risk of cancer of Barrett esophagus. Exact determination of invasion depth in the mucosa, respective submucosa is now established as prognostic marker for overall survival in Patients with early carcinomas and this classification is useful for therapy decisions (endoscopic versus surgical removal). In advanced Barrett carcinoma following neoadjuvant therapy the lymph node status (ypN) is a better prognostic factor than the ypT category. In metastasized tumors therapies targeting HER2/new, EGFR or c-Met have been investigated explicitly in Barrett carcinoma only in phase I/II studies, whereby the predictive value of appropriate molecular pathology investigations is not yet reliably established.

Abstract
Recently developed endoscopic resection (endoscopic submucosal dissection [ESD]/ endoscopic mucosal resection) has dramatically changed the therapeutic approach for Barrett's esophageal cancer. The rationale for endoscopic resection is that lesions confined to the mucosal layer have negligible risk for developing lymph node metastasis and can be successfully eradicated by endoscopic treatment as a curative treatment with minimal invasiveness. According to some reports that analyzed the rate of lymph-node involvement relative to the depth of mucosal or submucosal tumor infiltration, endoscopic resection is clearly indicated for intramucosal carcinoma and might be extended to lesions with invasion into the submucosa (<200 μm, sm1) because of the low risk for lymph node metastasis. Most Japanese experts recommend ESD for Barrett's esophageal cancer after accurate diagnosis of the margin of cancer using narrow band imaging with magnifying endoscopy because of its high curative rate. However, few studies have evaluated the long-term outcomes of endoscopic resection for Barrett's esophageal cancer in Japan. Further investigations should be conducted to establish endoscopic resection for Barrett's esophageal cancer.

Abstract
Endoscopic ultrasound (EUS) is considered the most accurate tool for the TNM staging of esophageal cancer, but its role in early Barrett's neoplasia is still debatable. The aim was to evaluate the utility of EUS in Barrett's patients prior to therapy. Retrospective review of 109 patients enrolled in a treatment protocol for Barrett's neoplasia in our institution. EUS assessment was classified as suspicious for invasion in 19 patients; 84% of them had no evidence of invasion in final pathology. The assessment of depth of invasion of Barrett's neoplasia based solely on EUS findings leads to overstaging in most patients.

Abstract
More than 10 years have passed since endoscopic submucosal dissection (ESD) was first developed in Japan. ESD enables en bloc complete resection of superficial gastrointestinal neoplasms regardless of the size and location of the lesions. With improvements in techniques and devices, excellent therapeutic results have been achieved despite the inherent technical difficulties of this procedure. ESD aiming for curative treatment can be performed for gastrointestinal neoplasms without risk of lymph node metastasis. Accurate histopathologic examination of the resected specimen is required to determine the risk of lymph node metastasis, for which en bloc resection is beneficial. Owing to the high success rate of en bloc complete resection and accurate histopathologic examination, tumour recurrence rates after ESD are reported to be very low in Japan. Excellent results of ESD in a large number of cases have also been reported from other Asian countries such as South Korea, Taiwan and China. Although scepticism exists among Western clinicians regarding the application of ESD, it is developing slowly and reports indicate promising results in some European countries. With further development of technologies, such as endoscopic robotics, ESD could become the worldwide treatment of choice for early gastrointestinal neoplasms.

Abstract
PURPOSE OF REVIEW The aim of this review is to evaluate the role of esophagectomy for high-grade dysplasia (HGD) and intramucosal adenocarcinoma (IMC) in light of recent advances in endoscopic therapy for Barrett's esophagus. RECENT FINDINGS Radiofrequency ablation (RFA) and endoscopic mucosal resection (EMR) are proven well tolerated and effective, at least in midterm follow-up. The application of these techniques has opened a new road for the local treatment of esophageal HGD and IMC. To safely employ these techniques, reliable and accurate staging of the esophageal neoplasm is essential. EMR has taken a central role, as it allows the pathologist to provide tumor-staging information necessary for an appropriate clinical management decision process. Unfortunately, both RFA and EMR have limitations that preclude their universal use in the treatment of early esophageal cancer. In some cases, esophagectomy still remains the best treatment option. The evolution of the minimally invasive approach to esophagectomy may improve outcomes of this major operation. SUMMARY A better understanding of the indications and limitations of endoscopic therapy for HGD and IMC permits a tailored approach to the management of patients with early esophageal adenocarcinoma. When indicated, the selection of a less morbid surgical technique has the potential to improve overall surgical and oncological outcomes.

Abstract
Esophageal adenocarcinoma is the most rapidly increasing cancer in western countries. High-grade dysplasia (HGD) arising from Barrett’s esophagus (BE) is the most important risk factor for its development, and when it is present the reported incidence is up to 10% per patient-year. Adenocarcinoma in the setting of BE develops through a well known histological sequence, from non-dysplastic Barrett’s to low grade dysplasia and then HGD and cancer. Endoscopic surveillance programs have been established to detect the presence of neoplasia at a potentially curative stage. Newly developed endoscopic treatments have dramatically changed the therapeutic approach of BE. When neoplasia is confined to the mucosal layer the risk for developing lymph node metastasis is negligible and can be successfully eradicated by an endoscopic approach, offering a curative intention treatment with minimal invasiveness. Endoscopic therapies include resection techniques, also known as tissue-acquiring modalities, and ablation therapies or non-tissue acquiring modalities. The aim of endoscopic treatment is to eradicate the whole Barrett’s segment, since the risk of developing synchronous and metachronous lesions due to the persistence of molecular aberrations in the residual epithelium is well established.

Abstract
Duplicated muscularis mucosae (MM) in early esophageal adenocarcinoma (EAC) can cause overstaging of the disease on endoscopic ultrasound and pathology specimens. No study has determined the correlation between lymph node metastasis and invasion in the space between duplicated MM in pathologic tumor stage (pT) 1 EAC. Hematoxylin and eosin-stained slides from surgically resected pT1 EAC (n=99) were reviewed for tumor configuration, grade, level of invasion (lamina propria/inner MM, space between duplicated MM, and submucosa), quantitative depth of invasion in millimeter, and lymphovascular invasion (LVI). These pathologic characteristics were correlated with lymph node status and recurrence-free survival (RFS). All specimens had duplicated MM with thick-walled blood vessels. Tumor differentiation was well in 37, moderate in 47, and poor in 15 specimens. EAC invaded the lamina propria/inner MM in 28 cases, duplicated MM space in 41 cases, and submucosa in 30 cases. LVI was identified in 23 tumors. Eleven patients had lymph node metastasis. Quantitative depth of invasion as a continuous variable (P=0.002), poorly differentiated histology (P=0.028), presence of LVI (P=0.001), and submucosal invasion versus duplicated MM/lamina propria invasion (P=0.02) were associated with increased risk of lymph node metastasis and shorter RFS by univariate analysis. By multivariate analysis, LVI was an independent predictor of lymph node status and RFS. EAC invasion into the space between duplicated MM confers a similar risk of lymph node metastasis and recurrence as those of intramucosal EAC, and LVI is the best predictor of lymph node status and RFS in pT1 EAC.
