Challenges and advancing strategies of endoscopic submucosal dissection for early gastric cancer: The puzzle of eCura C1. World J Gastrointest Endosc 2024; 16:439-444. [PMID: 39155999 PMCID: PMC11325872 DOI: 10.4253/wjge.v16.i8.439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2024] [Revised: 06/19/2024] [Accepted: 07/05/2024] [Indexed: 08/01/2024] Open
Abstract
In this editorial, we explore the challenges of managing noncurative resections in early gastric cancer after endoscopic submucosal dissection (ESD), starting from the consideration recently made by Zhu et al. Specifically, we evaluate the management of eCura C1 lesions, where decisions regarding further interventions are pivotal yet contentious. Collaboration among endoscopists, surgeons, and pathologists is underscored to refine risk assessment and personalize therapeutic management. Recent advancements in ESD techniques and interdisciplinary collaboration offer opportunities for outcome optimization in managing eCura C1 lesions. Moreover, despite needing further clinical validation, molecular biomarkers have emerged as promising tools for enhancing prognostication. This manuscript highlights the ongoing research attempts to define treatment paradigms effectively and evaluates the potential of emerging options, ultimately aiming to improve patient care and outcomes in this complex clinical scenario.

Abstract
PURPOSE Long-term outcomes of patients with positive lateral margins (pLMs) after endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). This study aimed to evaluate the remnant cancer and survival rates of patients with pLMs compared with those who underwent curative resection. MATERIALS AND METHODS A retrospective analysis was performed on consecutive patients with pLMs as the only non-curative factor of expanded indication who underwent ESD for EGC with a follow-up duration of 5 years or more. The rates of remnant cancer, recurrence, and survival were analyzed and compared to those of control patients who underwent curative resection by propensity score matching. RESULTS Among 3,515 patients treated with ESD between 2005 and 2018, 123 non-curative EGCs were retrospectively analyzed. A total of 108 patients were followed up without endoscopic or surgical resection for 8.2 years. The control group was matched in a 1:1 ratio with patients with EGC who underwent curative resection after ESD. The observation group with pLMs had a higher incidence of remnant cancer (25.9%; 28/108) compared to that in the curative resection group (0/108; P=0.000). The remaining tumors were treated with surgical or endoscopic resection, and no additional recurrences were observed. The overall survival analysis demonstrated no significant difference between the observation and curative resection groups (P=0.577). CONCLUSIONS No difference was observed in the overall survival rate between observation and curative resection groups. Therefore, observation may be a possible option for incomplete ESD with pLMs if continuous follow-up is performed.

Abstract
BACKGROUND The criteria for surgical intervention after non-curative endoscopic submucosal dissection (ESD) of early gastric cancer are unclear. We aimed to clarify the risk factors for residual cancer and lymph node metastasis after non-curative ESD and to identify recommendations for additional surgery. METHODS We collected data on 133 consecutive patients who underwent additional surgery after non-curative ESD of early gastric cancer at Nanjing Drum Tower Hospital from January 2013 to July 2022. Univariate and multivariate analyses were performed to seek risk factors of residual cancer and lymph node metastasis. RESULTS The incidence rates of residual cancer and lymph node metastasis were 13.5% (18/133) and 10.5% (14/133), respectively. There was neither residual tumor nor lymph node metastasis in 104 (78.2%) cases. Multivariate analyses elucidated that horizontal margin was an independent risk factor for local residual cancer, whereas lymphatic infiltration was an independent risk factor for lymph node metastasis. Patients with mixed histological types were more likely to suffer lymph node metastasis and further undergo additional surgery after non-curative ESD than pure histological type. CONCLUSIONS Additional gastrectomy with lymph node dissection was strongly recommended in patients with lymphatic infiltration after non-curative ESD of early gastric cancer. Patients with mixed histological type have a high propensity for lymph node metastasis and should be treated as a separate subtype.

Abstract
This document from the American Society for Gastrointestinal Endoscopy (ASGE) provides a full description of the methodology used in the review of the evidence used to inform the final guidance outlined in the accompanying Summary and Recommendations document regarding the role of endoscopic submucosal dissection (ESD) in the management of early esophageal and gastric cancers. This guideline used the Grading of Recommendations, Assessment, Development and Evaluation framework and specifically addresses the role of ESD versus EMR and/or surgery, where applicable, for the management of early esophageal squamous cell carcinoma (ESCC), esophageal adenocarcinoma (EAC), and gastric adenocarcinoma (GAC) and their corresponding precursor lesions. For ESCC, the ASGE suggests ESD over EMR for patients with early-stage, well-differentiated, nonulcerated cancer >15 mm, whereas in patients with similar lesions ≤15 mm, the ASGE suggests either ESD or EMR. The ASGE suggests against surgery for such patients with ESCC, whenever possible. For EAC, the ASGE suggests ESD over EMR for patients with early-stage, well-differentiated, nonulcerated cancer >20 mm, whereas in patients with similar lesions measuring ≤20 mm, the ASGE suggests either ESD or EMR. For GAC, the ASGE suggests ESD over EMR for patients with early-stage, well or moderately differentiated, nonulcerated intestinal type cancer measuring 20 to 30 mm, whereas for patients with similar lesions <20 mm, the ASGE suggests either ESD or EMR. The ASGE suggests against surgery for patients with such lesions measuring ≤30 mm, whereas for lesions that are poorly differentiated, regardless of size, the ASGE suggests surgical evaluation over endosic approaches.

Abstract
BACKGROUND AND AIMS The natural course of early gastric cancer (EGC) following endoscopic submucosal dissection (ESD) remains unclear. This study aimed to clarify the long-term clinical outcomes and risk factors of metachronous gastric neoplasm (MGN) 5 years after ESD for EGC. METHODS We performed a retrospective analysis of patients who underwent ESD for EGC from July 2005 to October 2015 in Seoul National University Hospital. Long-term clinical outcomes and risk factors of MGN after 5 years post-ESD were evaluated. RESULTS Among the 2059 patients who underwent ESD for EGC, 1102 were followed up for > 5 years. MGN developed in 132 patients 5 years after ESD. During the median follow-up period of 85 months, the cumulative incidences of MGN and metachronous gastric cancer were 11.7, 16.9, and 27.0 and 7.6, 10.8, and 18.7% after 5, 7, and 10 years, respectively. In multivariable analysis, male sex (odds ratio 1.770; P = 0.042), severe intestinal metaplasia (odds ratio 1.255; P = 0.000), tumor-positive lateral margin (odds ratio 2.711; P = 0.008), < 5 mm lateral safety margin (odds ratio 1.568; P = 0.050), and synchronous adenoma (odds ratio 2.612; P = 0.001) were positive predictive factors, and successful eradication of Helicobacter pylori (odds ratio 0.514; P = 0.024) was a negative predictive factor for MGN after 5 years post-ESD. CONCLUSION The cumulative MGN incidence was high even 5 years post-ESD for EGC. Meticulous long-term endoscopic follow-up is mandatory, especially in male patients with underlying intestinal metaplasia, tumor-positive lateral margins, lateral safety margins of < 5 mm, and synchronous adenomas.

Abstract
Background: Endoscopic resection is indicated for early or superficial gastrointestinal neoplasms with a negligible risk of lymph node metastasis. This procedure could preserve the organ while allowing en bloc resection of tumors, irrespective of the size and location of the lesion. Histological evaluation of the resected specimen determines whether curative resection, which implies a favorable long-term outcome, was achieved. If the resected specimen reveals non-curative, additional treatment is necessary as it is strongly associated with recurrence.Current Concepts: Surgical resection is recommended after non-curative resection of gastrointestinal neoplasms. However, rather than surgical resection, additional endoscopic treatment can be recommended if non-curative resection is solely because of the positive involvement at the horizontal resection margin without any other findings compatible with the non-curative resection criteria.Discussion and Conclusion: Adopting precise indications of endoscopic resection is important to reduce the risk of non-curative resection. If curative resection is not achieved after endoscopic resection, additional treatment should be considered to prevent local recurrence as well as lymph node metastasis.

Long-term Outcomes of Additional Endoscopic Treatments for Patients with Positive Lateral Margins after Endoscopic Submucosal Dissection for Early Gastric Cancer. Gut Liver 2021; 16:547-554. [PMID: 34462393 PMCID: PMC9289831 DOI: 10.5009/gnl210203] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 07/04/2021] [Accepted: 07/06/2021] [Indexed: 11/06/2022] Open
Abstract
Background/Aims It is uncertain whether additional endoscopic treatment may be chosen over surgery in patients with positive lateral margins (pLMs) as the only non-curative factor after endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). We aimed to compare the long-term outcomes of additional endoscopic treatments in such patients with those of surgery and elucidate the clinicopathological factors that could influence the treatment selection. Methods A total of 99 patients with 101 EGC lesions undergoing additional treatment after non-curative ESD with pLMs as the only non-curative factor were analyzed. Among them, 25 (27 lesions) underwent ESD, 29 (29 lesions) underwent argon plasma coagulation (APC), and 45 (45 lesions) underwent surgery. Clinicopathological characteristics and long-term outcomes were compared. Results Residual tumor was found in 73.6% of cases. The presence of multiple pLMs was associated with higher risk of residual tumor (p=0.046). During a median follow-up of 58.9 months, recurrent or residual lesions after additional ESD and APC were found in 4% (1/25) and 6.8% (2/29) of patients, respectively. However, all were completely cured with surgery or repeated ESD. There were no extragastric recurrences after additional endoscopic treatment. Lymph node metastasis was identified after additional surgery in one (2.2%) patient with an EGC showing histological heterogeneity. Conclusions Given the favorable long-term outcomes, additional ESD or APC may be an acceptable choice for patients with pLMs as the only non-curative factor after ESD for EGC. However, clincopathological characteristics such as multiple pLMs and histological heterogeneity should be considered in the treatment selection.

Abstract
Background/Aims This study examined the long-term outcomes of undifferentiated-type early gastric cancer (UD EGC) with positive horizontal margins (HMs) after endoscopic resection (ER) and compared them between additional surgery and nonsurgical management. Methods From 2005 to 2015, a total of 1,124 patients with UD EGC underwent ER at 18 tertiary hospitals in Korea. Of them, 92 patients with positive HMs as the only noncurative factor (n=25) or with both positive HMs and tumor size >2 cm (n=67) were included. These patients underwent additional surgery (n=40), underwent additional endoscopic treatment (n=6), or were followed up without further treatment (n=46). Results No lymph node (LN) metastasis was found in patients who underwent additional surgery. During a median follow-up of 57.7 months (interquartile range, 27.6 to 68.8 months), no LN or distant metastases or gastric cancer-related deaths occurred in the overall cohort. At baseline, the residual cancer rate was 57.8% (26/45) after additional surgery or ER. The 5-year local recurrence rate was 33.6% among patients who were followed up without additional treatment. The 5-year overall survival rates were 95.0% and 87.8% after additional surgery and nonsurgical management (endoscopic treatment or close follow-up), respectively (log-rank p=0.224). In the multivariate Cox regression analysis, nonsurgical management was not associated with an increased risk of mortality. Conclusions UD EGC with positive HMs after ER may have favorable long-term outcomes and a very low risk of LN metastasis. Nonsurgical management may be suggested as an alternative, particularly for patients with old age or chronic illness. (Gut Liver 2021;15-731)

Recurrence rate of intramucosal gastric cancer with positive vertical margin due to lesion damage during endoscopic submucosal dissection. Acta Gastroenterol Belg 2021; 84:289-294. [PMID: 34217177 DOI: 10.51821/84.2.289] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/21/2022]
Abstract
BACKGROUND AND STUDY AIM In principle, additional surgery is performed after endoscopic submucosal dissection for early gastric cancer if the vertical margin is positive, regardless of lesion damage. The recurrence rate of vertical margin-positive lesions due to lesion damage after endoscopic submucosal dissection is unknown, and unnecessary surgeries may be performed. In this study, we investigated whether there was a difference in the recurrence rate between vertical margin-positive lesions due to lesion damage and vertical margin-negative lesions. PATIENTS AND METHODS We included 1,294 intramucosal gastric cancer lesions that were resected by endoscopic submucosal dissection between January 2008 and December 2016, without additional surgery. The lesions were divided into the Damage and No damage groups based on vertical margin status. The Damage group had only one non-curative indication: a positive vertical margin due to lesion damage. The No damage group had no non curative indications. We compared the recurrence rate between the Damage and No damage groups. RESULTS The recurrence rates of the Damage and No damage groups were 0% (0/23; 95% confidence interval: 0-14.8%) and 0% (0/1,271; 95% confidence interval: 0-0.003%), respectively, with no statistically significant difference. CONCLUSIONS In intramucosal gastric cancer, the recurrence rate of vertical margin-positive lesions due to lesion damage was 0%, which did not differ from that of vertical margin-negative lesions with curative resection. Follow-up, instead of additional surgery, may be an option for patients with non-curative resection when the only non-curative indication is a positive vertical margin due to lesion damage.

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/Aims Patients treated with endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) are at risk of developing metachronous gastric cancer (MGC). The aim of this study was to evaluate the clinical outcomes of MGC after ESD for EGC between the re-ESD and surgery groups. Methods In total, data from 1,510 patients who underwent ESD for EGC from January 2005 to May 2014 were retrospectively reviewed, and data from 112 patients with MGC were analyzed according to the type of treatment, namely, re-ESD and surgery. The clinicopathological factors affecting the subsequent treatment and outcomes of MGC were evaluated. Results The median duration to the development of MGC was 47 months. In multivariate analysis, lower body mass index (BMI) (p=0.037) and multiplicity (p=0.014) of index cases were significantly associated with subsequent surgery for MGC. In cases of MGC, a diffuse or mixed-type Lauren classification (p=0.009), the depth of tumor mucosal invasion (p=0.001), and an upper stomach location (p=0.049) were associated with surgery. Overall survival was significantly shorter in the surgery group than in the re-ESD group after treatment for MGC (log-rank test, p=0.01). Conclusions Lower BMI and multiplicity of index cancers were significantly associated with the surgical resection of MGC. Close follow-up is needed to minimize additional treatment for cases at high risk of advanced MGC after ESD for EGC.

Abstract
BACKGROUND Prediction of remnant tumor is important in determining subsequent treatment options for gastric cancer patients with positive resection margin (RM) after endoscopic submucosal dissection (ESD). METHODS Based on the assumption that pathologic factors, including the length and type of involved RM, could potentially predict residual tumor, we evaluated 451 ESD specimens in patients with early gastric cancer. RESULTS Of 408 cases, 37 (9.1 %) showed positive RMs. RM involvement in gastric cancer ESD specimens was associated with extended or beyond ESD criteria, greater tumor size, poor differentiation, submucosal invasion, lymphovascular invasion, and upper third location. Among the 37 positive RM cases, residual tumor was present in seven (18.9 %). The presence of residual tumor was not significantly associated with any clinicopathologic parameters except for tumor size and RM status. The total length of the involved RM was the most significant factor associated with the presence of residual tumor (P < 0.008). A total length cut-off value of 6 mm yielded a sensitivity of 85.7 % and negative predictive value of 94.7 % for predicting remnant tumor at gastrectomy following ESD. CONCLUSIONS In conclusion, when the ESD specimen exhibits positive RM, a quantitative assessment of the involved RM should be included in the pathology report, as this can help the clinician predict remnant tumor and determine appropriate future treatment.

Abstract
BACKGROUND The optimal extent of lymph node dissection in patients receiving non-curative endoscopic submucosal dissection (ESD) and diagnosed with a positive vertical margin is unclear. This study attempted to identify optimal candidates for D2 lymph node dissection among these patients. METHODS This study included patients who underwent gastrectomy for primary gastric cancer following non-curative ESD with a positive vertical margin between January 2002 and December 2018. We classified the patients according to the positive vertical margin pattern into an obvious exposure group and a non-obvious exposure group. We developed a score model for predicting lymph node metastasis (LNM) using factors selected by multivariate analyses and beta regression coefficients, and the incidence of LNM was evaluated. RESULTS This study included 110 patients. LNM was detected in 17 patients (15%). We developed a predictive scoring system as follows: tumor size >30 mm (0, No; 1, Yes) + undifferentiated type tumor in the invasive front (0, No; 2, Yes) + depth of submucosal invasion > 1500 μm (0, No; 1, Yes) + obvious tumor exposure at the vertical margin (0, No; 1, Yes). In patients with 5 points, the incidence rates of all and group 2 LNM were as high as 60% and 40%, respectively. Conversely, in patients with fewer than 5 points, the incidence rates of all and group 2 LNM were just 11% and 5%, respectively. CONCLUSION In patients with 5 points according to our score model for predicting LNM, gastrectomy with D2 lymph node dissection is recommended.

Relevant risk factors and the prognostic impact of positive resection margins after endoscopic resection of gastrointestinal neuroendocrine tumors. Wideochir Inne Tech Maloinwazyjne 2020; 15:276-282.

Abstract
Introduction Endoscopic resection for the treatment of gastrointestinal neuroendocrine tumors has a risk of resection margin residues. The related risk factors and prognosis of post-endoscopic resection margin residues have not been fully evaluated. Aim To investigate the associated risk factors and prognostic impact of resection margin residues after endoscopic resection of gastrointestinal neuroendocrine tumors. Material and methods We conducted a retrospective analysis of 129 patients who underwent endoscopic resection for the treatment of gastrointestinal neuroendocrine tumors. Sex, age, location, diameter of tumor, depth of invasion, endoscopic treatment methods, endoscopic ultrasonography (EUS) evaluation, and the work experience of endoscopists were evaluated as potential risk factors. In addition, the prognoses of patients with positive resection margins were analyzed. Results A total of 18 (18/129, 14.0%) patients exhibited positive resection margins after endoscopic resection. Among 16 successfully followed-up patients, 1 died due to rupture of pulmonary artery aneurysms, 2 underwent supplementary surgical operations, and 2 underwent additional endoscopic submucosal dissection. The remaining 11 patients were periodically followed up, and no recurrences were found. The results of univariate analysis suggested that endoscopic treatment method, the depth of invasion, and EUS evaluation correlated with positive resection margin. Multivariate regression analysis suggested that the depth of invasion and EUS evaluation were risk factors for resection margin residues. Conclusions The depth of invasion and EUS evaluation are independent risk factors for positive resection margins after endoscopic resection. This finding suggests that a greater depth of invasion increases the risk for positive resection margins, while EUS evaluation before resection decreases this risk.

Abstract
Gastric cancer is one of the most frequent neoplasias in the digestive tract and is the result of premalignant lesion progression in the majority of cases. Opportune detection of those lesions is relevant, given that timely treatment offers the possibility of cure. There is no consensus in Mexico on the early detection of gastric cancer, and therefore, the Asociación Mexicana de Gastroenterología brought together a group of experts and produced the "Mexican consensus on the detection and treatment of early gastric cancer" to establish useful recommendations for the medical community. The Delphi methodology was employed, and 38 recommendations related to early gastric cancer were formulated. The consensus defines early gastric cancer as that which at diagnosis is limited to the mucosa and submucosa, irrespective of lymph node metástasis. In Mexico, as in other parts of the world, factors associated with early gastric cancer include Helicobacter pylori infection, a family history of the disease, smoking, and diet. Chromoendoscopy, magnification endoscopy, and equipment-based image-enhanced endoscopy are recommended for making the diagnosis, and accurate histopathologic diagnosis is invaluable for making therapeutic decisions. The endoscopic treatment of early gastric cancer, whether dissection or resection of the mucosa, should be preferred to surgical management, when similar oncologic cure results can be obtained. Endoscopic surveillance should be individualized.

Abstract
Gastric adenocarcinoma carries a poor prognosis, in part due to the late stage of diagnosis. Risk factors include Helicobacter pylori infection, family history of gastric cancer-in particular, hereditary diffuse gastric cancer and pernicious anaemia. The stages in the progression to cancer include chronic gastritis, gastric atrophy (GA), gastric intestinal metaplasia (GIM) and dysplasia. The key to early detection of cancer and improved survival is to non-invasively identify those at risk before endoscopy. However, although biomarkers may help in the detection of patients with chronic atrophic gastritis, there is insufficient evidence to support their use for population screening. High-quality endoscopy with full mucosal visualisation is an important part of improving early detection. Image-enhanced endoscopy combined with biopsy sampling for histopathology is the best approach to detect and accurately risk-stratify GA and GIM. Biopsies following the Sydney protocol from the antrum, incisura, lesser and greater curvature allow both diagnostic confirmation and risk stratification for progression to cancer. Ideally biopsies should be directed to areas of GA or GIM visualised by high-quality endoscopy. There is insufficient evidence to support screening in a low-risk population (undergoing routine diagnostic oesophagogastroduodenoscopy) such as the UK, but endoscopic surveillance every 3 years should be offered to patients with extensive GA or GIM. Endoscopic mucosal resection or endoscopic submucosal dissection of visible gastric dysplasia and early cancer has been shown to be efficacious with a high success rate and low rate of recurrence, providing that specific quality criteria are met.

[PMID: 31413533 PMCID: PMC6689811 DOI: 10.3748/wjg.v25.i29.3996] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2019] [Revised: 06/28/2019] [Accepted: 07/05/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The necessity of additional gastrectomy for early gastric cancer (EGC) patients who do not meet curative criteria after endoscopic submucosal dissection (ESD) is controversial.
AIM To examine the clinicopathologic characteristics of patients who underwent additional laparoscopic gastrectomy after ESD and to determine the appropriate strategy for treating those after noncurative ESD.
METHODS We retrospectively studied 45 patients with EGC who underwent additional laparoscopic gastrectomy after noncurative ESD from January 2013 to January 2019 at the Cancer Hospital of the Chinese Academy of Medical Sciences. We analyzed the patients’ clinicopathological data and identified the predictors of residual cancer (RC) and lymph node metastasis (LNM).
RESULTS Surgical specimens showed RC in ten (22.2%) patients and LNM in five (11.1%). Multivariate analysis revealed that positive horizontal margin [odds ratio (OR) = 13.393, 95% confidence interval (CI): 1.435-125, P = 0.023] and neural invasion (OR = 14.714, 95%CI: 1.087-199, P = 0.043) were independent risk factors for RC. Undifferentiated type was an independent risk factor for LNM (OR = 12.000, 95%CI: 1.197-120, P = 0.035). Tumors in all patients with LNM showed submucosal invasion more than 500 µm. Postoperative complications after additional laparoscopic gastrectomy occurred in five (11.1%) patients, and no deaths occurred among patients with complications.
CONCLUSION Gastrectomy is necessary not only for patients who have a positive margin after ESD, but also for cases with neural invasion, undifferentiated type, and submucosal invasion more than 500 µm. Laparoscopic gastrectomy is a safe, minimally invasive, and feasible procedure for additional surgery after noncurative ESD. However, further studies are needed to apply these results to clinical practice.

Abstract
Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) have been well-established methods of treating upper gastrointestinal neoplasia. The aim of this study was to identify the safety and effectiveness of endoscopic treatment for gastric neoplasia within a 2-day hospital stay.Between 2004 and 2015, a total of 914 patients with gastric neoplasia were treated with EMR or ESD within 2 days of hospitalization. The neoplasia sites, en bloc resection rates, pathology, local residual neoplasia rates, and major complications were evaluated retrospectively.The mean age was 63.4 years old, and 636 (69.6%) patients were male. Adenoma was the most common final diagnosis (60.9%), followed by adenocarcinoma (28.9%). The first follow-up endoscopy was performed 4.9 ± 1.1 months after the procedure, and an average of 4.4 endoscopic examinations were performed for 7.16 years (range, 2.1 to 10.2 years). Additional surgery was performed in 11 (1.2%) cases based on post-procedure pathology results. On follow-up endoscopy, a mean of 5.9 months after the procedure, there were 18 residual neoplasia cases (EMR = 13, ESD = 5). Only 4 (0.4%) patients returned to the emergency unit with delayed bleeding, but all 4 cases were successfully controlled with endoscopic treatment. There were no other complications such as delayed perforation or aspiration pneumonia during the 2 days in hospital.EMR and ESD within only 2 days in hospital showed safe and effective outcomes in terms of managing early gastric neoplasia with low complication and local residual rates.

Risk Factors Associated with Lymph Node Metastasis for Early Gastric Cancer Patients Who Underwent Non-curative Endoscopic Resection: a Systematic Review and Meta-analysis. J Gastrointest Surg 2019; 23:1318-1328. [PMID: 30187319 DOI: 10.1007/s11605-018-3924-5] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2018] [Accepted: 08/07/2018] [Indexed: 01/31/2023]
Abstract
BACKGROUND Recently, increased evidence indicated that additional surgery should be performed in highly selected patients with non-curative endoscopic resection. In this study, we performed a systematic review and meta-analysis to evaluate the risk factors associated with lymph node metastasis for the patients with non-curative endoscopic resection of early gastric cancer. METHODS The related studies were identified by searching PubMed and Embase databases. According to the status of lymph node metastasis, all patients were classified into node-negative group and node-positive group. The relevant clinicopathologic factors were extracted, and the pooled odds ratio (OR) and 95% confidence interval (CIs) were assessed using a fixed effects model or random effects model. RESULTS A total of nine relevant studies involving 1720 early gastric cancer patients who underwent additional surgery following the non-curative endoscopic resection were included in this meta-analysis. The results indicated that deeper submucosal invasion (SM2) (OR 3.44, 95% CI 1.94-6.10, P < 0.001; I2 = 0%), positive vertical margin (OR 2.35, 95% CI 1.57-3.53, P < 0.001; I2 = 0%), lymphatic invasion (OR 11.06, 95% CI 5.47-22.36, P < 0.001; I2 = 0%), and vascular invasion (OR 2.79, 95% CI 1.68-4.64, P < 0.001; I2 = 0%) were significantly associated with lymph node metastasis for these patients. However, horizontal margin, tumor size, differentiation type, and ulceration were not identified as risk factors associated with lymph node metastasis. CONCLUSION Lymphatic invasion, vascular invasion, deeper submucosal invasion (SM2), and positive vertical margin should be strongly considered in selecting the candidates for additional surgery treatment.

Abstract
If a lesion does not meet the expanded indication criteria for treatment with endoscopic therapy for early gastric cancer or has a positive resection margin, it is regarded as suitable for non-curative resection. Non-curative resection is closely related to the risk of local recurrence, lymph node metastasis, and poor prognosis. If the result is confirmed as non-curative resection, additional treatment should be considered depending on the risks of residual tumor, local recurrence, and lymph node metastasis. As lymphatic invasion is the most important risk factor of recurrence and poor prognosis, surgical treatment should be considered if lymphatic invasion is present. If patients are not suitable for additional surgery owing to old age or coexisting severe disease, close surveillance can be an alternative treatment option.

Abstract
Background/Aims Endoscopic submucosal dissection (ESD) has been regarded as a curative treatment for early gastric cancer (EGC) in indicated cases. The aim of this study was to evaluate the nationwide long-term clinical outcomes of ESD for EGC in Korea. Methods A prospective multicenter cohort study was performed to evaluate the long-term efficacy of ESD for EGC within pre-defined indications at 12 institutes in Korea. The cases that met the expanded criteria upon pathological review after ESD were followed for 5 years. The primary outcome was 5-year disease specific free survival. Results Six hundred ninety-seven patients with 722 EGCs treated with ESD were prospectively enrolled and followed for 5 years. Complete resection was achieved in 81.3% of the cases, and curative resection was achieved in 86.1%. During the 5-year follow-up, the overall survival rate was 96.6%, and the disease specific free survival rate was 90.6%. Local recurrence developed in 0.9%, and metachronous tumor development occurred in 7.8%; both conditions were treated by endoscopic or surgical treatment. Distant metastasis developed in 0.5% during follow-up. Conclusions ESD showed excellent long-term clinical outcomes and can be accepted as a curative treatment for patients with EGC who meet the expanded criteria in final pathology studies.

Abstract
BACKGROUND AND AIMS This study stratified the risk of developing metachronous gastric cancer (MGC) after curative endoscopic submucosal dissection (ESD) of early gastric cancer (EGC) to enable customization of endoscopic surveillance for MGC. METHODS A total of 1115 patients who underwent curative ESD based on the expanded criteria for differentiated EGC from 2005 to 2014 at a single tertiary hospital were enrolled in this retrospective cohort study. They were followed up with annual endoscopy for a median of 50.1 months. Helicobacter pylori and histologic intestinal metaplasia (IM) were evaluated. The Kaplan-Meier method and Cox regression analysis were used for risk stratification. RESULTS Three risk groups were identified: group 1 comprised patients with a synchronous neoplasm; group 2 comprised male patients with corpus IM; and group 3 comprised male patients without corpus IM or female patients. The 5- and 7-year cumulative risks (95% confidence interval [CI]) for metachronous recurrence were 15.1% (95% CI, 7.7-22.5) and 26.1% (95% CI, 14.9-37.3), respectively, in group 1; 5.6% (95% CI, 3.1-8.1) and 9.3% (95% CI, 5.4-13.2), respectively, in group 2; and 3.8% (95% CI, 1.6-6.0) and 4.9% (95% CI, 2.4-7.4), respectively, in group 3 (P < .001 by log-rank test). The incidence of MGCs increased constantly even after 5 years in groups 1 and 2 but not in group 3. There was not enough evidence to show an association between H pylori eradication and metachronous recurrence in the data. CONCLUSIONS Meticulous annual endoscopic surveillance for MGC for more than 5 years is recommended for patients with synchronous neoplasm. Endoscopic surveillance may also be extended beyond 5 years in male patients with corpus IM.

Abstract
BACKGROUND AND AIMS No well-established treatment strategies exist for lateral margin positivity (LM+) alone after endoscopic resection (ER) of early gastric cancer (EGC). Thus, we aimed to clarify a treatment strategy for non-curative resection (non-CR) with LM+ alone after ER in EGC. METHODS Among 2065 patients with EGC treated by ER, 76 (3.6%) with only LM+ after non-CR of EGC were reviewed retrospectively. Of these, 28 underwent gastrectomy, 25 underwent argon plasma coagulation (APC), and 23 underwent repeat ER (re-ER). We analyzed the clinicopathologic characteristics of all patients and compared those who underwent additive surgery, APC, or re-ER. RESULTS Of the 76 patients, 28 (36.8%) fulfilled the absolute criteria and 48 (63.2%) the expanded criteria for ER. Among the latter patients, the proportion undergoing additive surgery was 75.0%, higher than that of patients in the former group (P = .014). Residual cancer cells were observed in 70.6% of patients after additive surgery or re-ER. Residual cancer cells were observed significantly more often in patients with undifferentiated-type than in those with differentiated-type EGC (P = .02). However, no lymph node metastasis was observed in any patient after additive surgery. CONCLUSIONS Our results suggest that endoscopic treatment may be a sufficient additive therapy for patients with LM+ alone after ER, irrespective of whether the absolute or expanded ER criteria are used. However, as complete ablation of remnant cells cannot be guaranteed, re-ER is a better additive treatment than APC.

Abstract
BACKGROUND Metachronous gastric tumor (MGT) is one of major concerns after endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). Optimal follow-up strategy has not been yet well-established. The aim of this study was to identify the different clinical features of the patients according to the time interval to development of MGT. METHODS Among 1,780 consecutive patients with EGC who underwent ESD between 2005 and 2014, 115 patients with MGT were retrospectively reviewed. MGT was defined as secondary gastric cancer or dysplasia detected > 1 year after initial ESD. Clinicopathological factors associated with early development of MGT were evaluated. RESULTS The median interval to development of MGT was 37 months. In univariate analysis, the median interval to MGT was shorter if EGC lesion was non-elevated type (39.4 vs 57.0 months, p = 0.011), or synchronous primary lesion was absent (39.8 vs 51.4 months, p = 0.050). In multivariate Cox's proportional hazards analysis, the hazard ratios for early occurrence of MGT were 1.966 (95% CI: 1.141-3.386, p = 0.015) and 1.911 (95% CI: 1.163-3.141, p = 0.011), respectively. There was no significant difference in overall survival after diagnosis of MGT between the early occurrence group and the late occurrence group. CONCLUSIONS Non-elevated gross type and absence of synchronous gastric tumor were independent risk factors for early development of MGT. Meticulous endoscopic inspection is especially important for the detection of MGT during the early follow-up period in patients with these initial tumor characteristics.

Abstract
The cases of non-curative endoscopic resection (NCR) of early gastric cancer have increased due to the widespread use of endoscopic submucosal dissection (ESD). NCR is associated with augmenting chances of local recurrence and lymph node metastasis (LNM). Therefore, some additional treatment strategies after NCR are needed. Treatment strategies for NCR should be determined by considering the risk of residual tumor or local recurrence and LNM. Additional surgical treatment such as gastrectomy and lymph node dissection are recommended in patients who have high-risk of LNM. Close observation without additional treatment is considered for selected patients with a less possibility of local recurrence or LNM. Also it may be suggested if there is no or less benefit from surgery in elderly patients or patients with underlying diseases. Additional endoscopic procedures including ESD, endoscopic mucosal resection or argon coagulation therapy are suggested alternatively for highly selected patients not at risk of LNM based on the absolute or expanded criteria of ESD.

[PMID: 27282267 PMCID: PMC5221865 DOI: 10.5009/gnl15549] [Citation(s) in RCA: 38] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2015] [Revised: 12/23/2015] [Accepted: 01/19/2016] [Indexed: 12/22/2022] Open
Abstract
Background/Aims Endoscopic submucosal dissection (ESD) has been an established treatment for indicated early gastric cancer (EGC) without deterioration of quality of life (QOL) compared with surgical resection. The aim of this study was to evaluate long-term QOL in patients undergoing ESD for EGC. Methods Patients scheduled to undergo curative ESD for EGC were prospectively enrolled from 12 institutions between May 2010 and December 2011. Assessments of QOL with Korean versions of the European Organization for Research and Treatment of Cancer (EORTC) QOL questionnaire-core (QLQ-C30) and a gastric cancer-specific questionnaire (STO22) were performed at baseline and at 7 days, 3 months, and 6 months after ESD. Results A total of 666 subjects were assessed for QLQ-C30 and QLQ-STO22. The mean QLQ-C30 score was 69.5 at baseline, 68.8 at 7 days, 73.1 at 3 months, and 73.2 at 6 months. The global health status on the EORTC QLQ-C30 was significantly improved after 3 and 6 months (p=0.0003 and p<0.0001, respectively). The QLQ-C30 and STO22 scores were not significantly different, or they only slightly deteriorated between before and immediately after ESD, but they were significantly improved after 3 and 6 months (p<0.05). Conclusions QOL did not deteriorate immediately after ESD, and it improved more significantly at up to 6 months in patients who underwent curative ESD for EGC without significant complications.

Abstract
BACKGROUND Whether surveillance strategy after curative endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) differs in young patients is unclear. This study aimed to evaluate the risk of metachronous and extragastric recurrence in young patients with EGC after curative ESD. METHODS We retrospectively enrolled 1237 consecutive patients who underwent curative ESD for EGC from 2005 to 2014 at a single tertiary hospital. The patients were divided into group 1 (<50 years of age, n = 86), group 2 (age 50-74, n = 985), or group 3 (≥75 years of age, n = 166). The clinical characteristics and outcomes were compared among the three age groups. RESULTS Group 1 had more frequent Helicobacter pylori infection (P < 0.001), less frequent intestinal metaplasia (P = 0.021), and more frequent undifferentiated tumors (P = 0.039). Although the 5-year risk of developing metachronous recurrence appeared to be lower in group 1 (2.7%) than in groups 2 (8.6%) or 3 (8.7%), the risk became quite similar at the 7-year follow-up (6.4, 12.7, and 8.7% for groups 1, 2, and 3, respectively; P = 0.409 by log-rank test). Extragastric recurrences developed in only 2 cases in group 2 (0.2%). CONCLUSIONS Surveillance for metachronous and extragastric recurrence after curative ESD in patients <50 years of age should not be different from that in patients ≥50 years of age. Endoscopic surveillance for metachronous recurrence should be continued for longer than 5 years, even in young patients.

Long-term outcomes of endoscopic submucosal dissection for early gastric cancer: a multicenter collaborative study. Gastric Cancer 2017; 20:45-52. [PMID: 27807641 DOI: 10.1007/s10120-016-0664-7] [Citation(s) in RCA: 66] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2016] [Accepted: 10/19/2016] [Indexed: 02/07/2023]
Abstract
OBJECTIVE The indications for endoscopic submucosal dissection (ESD) in patients with early gastric cancer (EGC) have been expanded. However, the long-term outcomes of ESD remain unclear. We retrospectively investigated the long-term outcomes of ESD in patients with EGC. METHODS We retrospectively studied patients with EGC who underwent ESD at 11 institutions between January 2003 and December 2010. A total of 6456 patients (7979 lesions) who met the absolute indications for ESD and 4202 patients (5781 lesions) who met the expanded indications for ESD were studied. Clinicopathological features, clinical course, and outcomes were studied in 67 patients in whom local recurrence or metastatic recurrence was diagnosed as of March 31, 2014. The median follow-up period was 56 months. RESULTS Local recurrence was diagnosed in 14 patients (0.22%) who met the absolute indications and 53 patients (1.26%) who met the expanded indications. The rate of local recurrence was significantly higher in patients with expanded-indication lesions (p < 0.05). As additional treatment for recurrence, most patients received endoscopic treatment. Metastatic recurrence did not develop in any patient with absolute-indication lesions, but was diagnosed in 6 patients (0.14%) with expanded-indication lesions (p < 0.05). The histological type was undifferentiated mixed type in half the patients. Three patients died of primary gastric cancer. CONCLUSIONS ESD for expanded-indication lesions of EGC is considered an effective therapy associated with an extremely low rate of metastatic recurrence on long-term follow-up. However, fully informed consent concerning the risk of metastatic recurrence should be obtained before ESD, and close postoperative follow-up is essential.

Abstract
Background/Aims To identify the risk factors for metachronous gastric neoplasms in patients who underwent an endoscopic resection of a gastric neoplasm. Methods We prospectively collected clinicopathologic data and measured the methylation levels of HAND1, THBD, APC, and MOS in the gastric mucosa by methylation-specific real-time polymerase chain reaction in patients who underwent endoscopic resection of gastric neoplasms. Results A total of 257 patients with gastric neoplasms (113 low-grade dysplasias, 25 high-grade dysplasias, and 119 early gastric cancers) were enrolled. Metachronous gastric neoplasm developed in 7.4% of patients during a mean follow-up of 52 months. The 5-year cumulative incidence of metachronous gastric neoplasm was 4.8%. Multivariate analysis showed that moderate/severe corpus intestinal metaplasia and family history of gastric cancer were independent risk factors for metachronous gastric neoplasm development; the hazard ratios were 4.12 (95% confidence interval [CI], 1.23 to 13.87; p=0.022) and 3.52 (95% CI, 1.09 to 11.40; p=0.036), respectively. The methylation level of MOS was significantly elevated in patients with metachronous gastric neoplasms compared age- and sex-matched patients without metachronous gastric neoplasms (p=0.020). Conclusions In patients who underwent endoscopic resection of gastric neoplasms, moderate/severe corpus intestinal metaplasia and a family history of gastric cancer were independent risk factors for metachronous gastric neoplasm, and MOS was significantly hypermethylated in patients with metachronous gastric neoplasms.

Abstract
Gastric cancer is one of the most common and lethal cancers in the world. In Portugal, it is a major health problem presenting one of the highest incidence rates among European countries. In most Western countries, gastric cancer is generally diagnosed in advanced stages. Nevertheless, with the widespread use of upper endoscopy, gastric superficial neoplastic lesions are being increasingly recognized and diagnosed. However, there are no clear recommendations regarding who should be screened for its presence and only recently guidelines concerning the evaluation and management of these lesions were published. In this review, we summarize the current scientific evidence regarding diagnosis and management of gastric superficial neoplastic lesions. Topics like screening, diagnosis, endoscopic evaluation, management, treatment, pathologic evaluation and follow-up of patients with these lesions are covered and areas of future research are discussed. Whenever possible, evidence-based recommendations are made, and on the other cases expert opinion is presented.

Abstract
BACKGROUND Mutations in DNA of mismatch repair (MMR) genes result in failure to repair errors that occur during DNA replication in microsatellites, resulting in accumulation of frameshift mutations in these genes and leading to DNA mismatch replication errors and microsatellite instability. Gastric cancers (GCs) with high MSI (MSI-H) are a well-defined subset of carcinomas showing distinctive clinicopathological features. In this study we investigated the rate of MSI and the correlation between MSI status and clinicopathological features of GC. MATERIAL AND METHODS The study included 107 patients with GCs: 61 with advanced gastric cancers (AGC) and 46 with early gastric cancer (EGC). MSI deficiency in GCs was assessed by the immunohistochemical analysis of expression of MMR proteins - MLH1, MSH2, MSH6, and PMS2 - using formalin-fixed and paraffin-embedded tissue. RESULTS A total of 6 (5.6%) MSI-H were observed. The loss of MMR proteins expression was associated with the intestinal type of GC in Lauren classification, and tubular and papillary architecture in WHO classification. There was no statistically significant association between negative MMR expression and other selected clinical parameters: age, sex, tumor location, depth of invasion (EGC and AGC), lymph nodes status, presence of the ulceration, and lymphocytic infiltrate. CONCLUSIONS In the present era of personalized medicine, the histological type of GC and MMR proteins status in cancer cells are very important for the proper surveillance of patients with familial GC and sporadic GCs, as well as for selecting the proper follow-up and treatment. Larger collaborative studies are needed to verify the features of MSI-H GCs in Poland.

Abstract
Endoscopic resection of early gastric cancer is defined as incomplete when tumor cells are found at the resection margin upon histopathological examination. However, a tumor-positive resection margin does not always indicate residual tumor; it can also be caused by tissue contraction during fixation, by the cautery effect during endoscopic resection, or by incorrect histopathological mapping. Cases of highly suspicious residual tumor require additional endoscopic or surgical resection. For inoperable patients, argon plasma coagulation can be used as an alternative endoscopic treatment. Immediately after the incomplete resection or residual tumor has been confirmed by the pathologist, clinicians should also decide upon any additional treatment to be carried out during the follow-up period.

Abstract
BACKGROUND AND AIM Although follow-up endoscopy is routinely performed after endoscopic resection (ER) for early gastric cancer (EGC), it remains unclear whether resection scar biopsies should also be taken. This study sought to predict local recurrence at the ER scar on the basis of endoscopic criteria after margin-negative EGC resection and to determine the necessity of taking scar biopsies. METHODS All consecutive patients with EGC who underwent margin-negative ER in June 1995 to December 2011 and developed recurrence at the scar were identified. Each case was matched by four controls with EGC and margin-negative ER but without local recurrence for age, sex, and en-bloc resectability (en-bloc vs. piecemeal resection). Endoscopic data were reviewed by consensus of two endoscopists. Key endoscopic criteria were gross morphology (evenly elevated, unevenly elevated, and flat), hyperemic change, mucosal defect, and spontaneous bleeding. RESULTS Of 3037 cases, which underwent margin-negative ER, 22 developed local recurrence (mean age, 63.8 years; 72.9% male). En-bloc resection was achieved in 20 of the 22 (90.9%). Flat endoscopic morphology without hyperemic changes predicted non-recurrence at the scar with a sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 95.5%, 68.2%, 2.6%, 99.94%, and 73.6%, respectively. For patients who underwent en-bloc resection for differentiated EGC, these values were 100%, 71.4%, 3.0%, 100%, and 75.8%, respectively. CONCLUSIONS Routine follow-up biopsies may be unnecessary when follow-up endoscopy reveals flat mucosa without hyperemic changes at the scar, especially for en-bloc resected and differentiated EGCs.

Additional surgery for non-curative resection after endoscopic submucosal dissection for gastric cancer: a retrospective analysis of 200 cases. Surg Today 2016; 47:202-209.

Abstract
PURPOSE Endoscopic submucosal dissection is recommended for early gastric cancer with a low risk of lymph node metastasis. When the pathological findings do not meet the curative criteria; then, an additional gastrectomy with lymph node dissection is recommended. However, most cases have neither lymph node metastasis nor a local residual tumor during an additional surgery. METHODS This was a single-institutional retrospective cohort study, analyzing 200 patients who underwent an additional gastrectomy after non-curative endoscopic submucosal dissection from January 2005 to October 2015. We reviewed the patients' clinicopathological data and evaluated the predictors for the presence of a residual tumor. RESULTS Histopathology revealed lymph node metastasis in 15 patients (7.5 %) and a local residual tumor in 23 (11.5 %). A multivariable analysis revealed macroscopic findings (flat/elevated type) (p = 0.011, odds ratio = 4.63), lymphatic invasion (p < 0.0001, odds ratio = 14.2), and vascular invasion (p = 0.04, odds ratio = 4.00) to be predictors for lymph node metastasis. A positive vertical margin (p = 0.0027, odds ratio = 3.26) and horizontal margin (p = 0.0008, odds ratio = 5.74) were predictors for a local residual tumor. All cases with lymph node metastasis had lymphovascular invasion with at least one other non-curative factor. CONCLUSIONS The risk of a residual tumor can, therefore, be estimated based on the histopathology of endoscopic submucosal dissection samples. Lymphovascular invasion appears to be a pivotal predictor of lymph node metastasis.

Abstract
OBJECTIVE This study aimed to systematically assess the relevant risk factors of positive lateral margin (LM) after en bloc resection of early gastric adenocarcinoma. METHODS A total of 242 patients who had undergone endoscopic submucosal dissection (ESD) due to early gastric lesions from January 2009 to March 2015 were included in the study. Clinicopathological features of the lesions and the risk factors related to positive LM were analyzed. RESULTS The curative rate was 82.2% and positive LM was found in 12.4% of the lesions. Univariate analysis showed that positive LM was significantly associated with the tumor location (at the upper third of the stomach), size (>3 cm), histological findings, the presence of lymphovascular invasion and deeper invasion depth. Moreover, positive LM had a higher incidence of recurrent or residual tumors. A multivariate analysis showed that the location, tumor size and histological classification of tumors were independent risk factors for positive LM. CONCLUSIONS Positive LM is closely related to the upper third of stomach, a tumor larger than 3 cm and a mixed-type carcinoma. Additionally, positive LM has a predilection for recurrent or residual tumors.

Abstract
BACKGROUND The aim of this study was to identify the risk factors for residual/recurrent tumors in patients with a tumor-positive lateral resection margin (LRM+) after endoscopic resection of early gastric cancer (EGC) and to establish the criteria for performing additional treatment. METHODS A retrospective analysis was performed on consecutive patients who underwent endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) of EGC. Clinicopathological characteristics and risk factors for residual/recurrent tumor in LRM+ patients were analyzed. RESULTS Eighty-two patients (84 lesions) with LRM+ after EMR (n = 45) or ESD (n = 39) were enrolled. Forty patients underwent additional gastrectomy or ESD, and 44 were closely observed. The residual/recurrent tumor rate was 34.5 % (29 of 84 lesions). Univariate analysis found that the residual/recurrent tumor was associated with the endoscopic resection type (EMR), undifferentiated histology, number of involved directions, rate of lateral resection margin involvement and the total length (mm) of the lateral resection margin involved by the tumor. In multivariate logistic regression analysis, undifferentiated histology and rate (%) were independent risk factors (odds ratio [OR] 5.28, 95 % confidence interval [CI] 1.13-24.72, p = 0.035 and OR 1.08, 95 % CI 1.03-1.14, p = 0.004, respectively). Clinicopathological factors that were identified from the univariate and multivariate analyses were scored in order to predict residual/recurrent tumors. CONCLUSION We suggest a scoring system for additional treatment in patients with LRM+ after endoscopic resection of EGC based on the development of residual/recurrent tumors. This scoring system enables a more detailed selection of cases and may be useful in determining further treatment.

Abstract
BACKGROUND The necessity of additional gastrectomy for patients not meeting the inclusion criteria after endoscopic submu cosal dissection (ESD) is controversial. The aim of this study was to elucidate the risk factors for lymph node metastasis (LNM) and residual cancer (RC) in patients not meeting the inclusion criteria after ESD and to determine additional treatment strategies. METHODS Of 1443 gastric cancer patients who underwent ESD between 2004 and 2013, 167 patients diagnosed as having a lesion not meeting the inclusion criteria after ESD were retrospectively analyzed. Of the 167 cases, 100 cases underwent additional gastrectomy, and 67 cases were observed without surgery. RESULTS Overall, 9.0 % (9/100) and 9.0 % (9/100) of patients not meeting the inclusion criteria after ESD presented with LNM and RC, respectively, but neither was observed in 83 patients (83.0 %). Multivariate analysis revealed that lymphovascular involvement (LVI) (OR 38.38; 95 % CI 1.94-761.43, p = 0.017) and undifferentiated type (OR 45.58; 95 % CI 2.88-720.94, p = 0.007) were independent risk factors for LNM, and positive horizontal margin was an independent risk factor for RC (OR 9.48; 95 % CI 1.72-52.13, p = 0.010). In differentiated types without LVI, no cases had LNM (0/38) in the additional gastrectomy group, and there was no lymph node or distant recurrence (0/39) in the observation group. CONCLUSIONS Additional treatment is necessary for patients with LVI, undifferentiated type, and positive horizontal margin. Careful follow-up may be acceptable for patients with the differentiated type without LVI, especially for the elderly or patients with severe comorbidities.

What are the risk factors for residual tumor cells after endoscopic complete resection in gastric epithelial neoplasia? Surg Endosc 2015; 29:487-92.

Abstract
BACKGROUND In early gastric cancer (EGC) and gastric adenoma, residual tumors may develop despite complete endoscopic resection (ER). To improve the chance of curative resection, we investigated the risk factors of residual tumor development in completely resected gastric epithelial neoplasia after ER. METHODS In total, 3,879 gastric epithelial neoplasms showing complete resection after ER were examined; 46 (1.2 %) residual tumors were found upon follow-up endoscopy. Clinicopathological characteristics were evaluated between those with and without residual tumors. RESULTS For gastric adenoma, high-grade dysplasia and severe intestinal metaplasia (IM) in the background mucosa were significantly associated with residual tumors. For EGC, poorly differentiated adenocarcinoma (PD), signet ring cell carcinoma (SRC), having a minimum lateral safety margin of <3 mm, and localization in the upper third of the stomach were significantly associated with residual tumors. Multivariate analysis revealed that a lateral safety margin of <3 mm (OR 13.8; p < 0.001), PD (OR 16.3; p = 0.014), and SRC (OR 9.8; p = 0.009) among EGC patients, and severe IM in the background mucosa (OR 9.0; p = 0.024) among gastric adenoma patients, were significantly associated with residual tumors. CONCLUSIONS For neoplasms with undifferentiated histology (PD or SRC), short-term endoscopic follow-up may help to detect residual tumors that form after complete resection via ER. For EGC, the lateral margin may be considered safe if greater than 3 mm. However, the possibility of satellite lesions should be investigated when the gastric adenoma to be resected is surrounded by severe IM.

Abstract
BACKGROUND No residual disease (NRD) can be found in the specimen after endoscopic resection (ER) of biopsy-proven gastric neoplasm. This study aimed to evaluate the endoscopic and pathologic characteristics of patients with NRD and identify the cause and long-term prognosis. METHODS Medical records of patients who underwent ER for biopsy-proven gastric neoplasms at a single tertiary hospital between January 2005 and November 2014 were retrospectively reviewed. Patients whose post-ER histology was revealed as NRD were included. Overall incidence, clinicopathologic characteristics, cause, and long-term prognosis were analyzed. RESULTS NRD was detected in 143 (3.2%) of 4401 cases of gastric neoplasms treated with ER. Mean endoscopic size of the initial lesion was 8.15 ± 6.64 mm; in 93 cases (65.0%), the lesion was located in the lower third of the stomach. Initial pathologic diagnosis was as follows: adenoma (n = 110), carcinoma (n = 29), and atypical gland (n = 4). The causes of NRD were minute lesions removed by biopsy in 140 patients, pathologic misdiagnoses in two, and localization error in one. Local recurrence was detected in five patients (3.6%) with minute lesions during follow-up and treated with argon plasma coagulation (n = 4) or re-ER (n = 1). Synchronous (n = 5, 3.6%) and metachronous gastric lesions (n = 6, 4.3%) were also detected during follow-up. CONCLUSIONS The main cause of NRD was minute lesions which might be completely removed by initial diagnostic biopsy. These cases showed a minimal rate of local recurrence and synchronous or metachronous gastric neoplasms. Careful follow-up is also mandatory for detection of residual disease.

Abstract
BACKGROUND There is often a discrepancy between results from endoscopic forceps biopsy and resected specimen. We aimed to identify endoscopic predictors for undifferentiated histology in differentiated gastric neoplasms prior to endoscopic resection. METHODS Medical records of the patients who underwent endoscopic submucosal dissection (ESD) for biopsy-proven differentiated gastric neoplasms at Seoul National University Hospital between July 2005 and July 2014 were retrospectively reviewed. The lesions were divided into two groups based on the final histologic result of ESD: differentiated adenocarcinoma (DA group) and undifferentiated histology (UDH group). The discordant rate, clinicopathologic characteristics, and endoscopic factors were analyzed. RESULTS A total of 1641 early gastric cancers from 1615 patients were included. Of these, 1556 (94.8%) were diagnosed as DA and 85 (5.2%) as UDH. The mean age was significantly lower, and number of women was higher in the UDH group than in the DA group. On multivariate analysis, age <65 years [odds ratio (OR) 1.75, 95 % confidence interval (CI) 1.10-2.80], female sex (OR 3.19, 95% CI 2.00-5.08), endoscopic size >10 mm (OR 1.81, 95% CI 1.12-2.92), depressed type (OR 2.85, 95% CI 1.56-5.21), nodularity (OR 2.83, 95% CI 1.59-5.05), and whitish discoloration (OR 19.64, 95% CI 6.98-55.25) were independent predictors. CONCLUSIONS Female sex, age <65 years, large endoscopic size, depressed morphology, surface nodularity, and whitish discoloration were predictors for UDH. Meticulous attention should be paid to the lesions with these endoscopic predictors for determining the risk of UDH prior to endoscopic resection.

Abstract
BACKGROUND With the widespread use of endoscopic submucosal dissection (ESD) in patients with early gastric cancer (EGC), the number of cases with incomplete resection due to positive lateral resection margins (LM+) is increasing. Local recurrence, which occurs frequently in LM+ cases, is an important issue. This study aimed to clarify the clinicopathological factors related to tumor recurrence in LM+ cases after ESD for EGC. METHODS From January 2005 to December 2012, a total of 1,083 patients with EGC underwent ESD at our hospital. Of these, cases with a pathological diagnosis of LM+ were included in this study. Patients with positive vertical resection margins, those who underwent surgical resection immediately or were followed up for less than 6 months after ESD, were excluded. RESULTS A total of 55 LM+ cases after ESD for EGC were enrolled. Incorrect delineation of a lesion that extended pathologically beyond the ESD marking dots was the main cause of LM+. Local recurrence was found in 20 (36.4 %) patients (median follow-up period, 23 months). Local recurrence rates related to LM+ length were as follows: 7/29 (24.1 %) in 2 mm, 6/16 (37.5 %) in 4 mm, 1/3 (33.3 %) in 6 mm, 4/5 (80 %) in 8 mm, and 2/2 (100 %) in ≥ 10 mm. In multivariate analysis, tumor size > 2 cm (OR 4.48, 95 % CI 1.18-16.99, p = 0.027), and LM+ length > 6 mm (OR 7.65, 95 % CI 1.15-50.70, p = 0.035) were independent risk factors for tumor recurrence. CONCLUSION To decrease the risk of LM+, it is highly important to accurately delineate the lateral margins during ESD; when the final histopathological result is LM+, cases with LM+ length >6 mm or tumor size > 2 cm should be considered for additional surgical resection or re-ESD because of a high risk of tumor recurrence.

Abstract
BACKGROUND In early gastric cancer (EGC) cases with lymphovascular invasion or positive vertical margins after endoscopic submucosal dissection (ESD), additional radical gastrectomy is performed on principle. However, an additional surgery is often difficult to consider if the surgical approach itself is challenging or the patient refuses surgery. In such cases, only close surveillance is performed without additional surgical procedures. This study aimed to examine the difference in clinical prognosis of EGC cases with lymphovascular invasion or positive vertical margins after ESD either with or without surgery. METHODS We retrospectively studied 83 patients with lymphovascular invasion or positive vertical margins after ESD from July 2005 to November 2013. RESULTS Of the 83 patients, 45 (54.2%) underwent radical additional gastrectomy (surgical group) and 38 (45.8%) were under close surveillance without surgical or endoscopic treatments (close surveillance group.) The cancer-free survival period was 78.3 ± 3.4 months in the surgical group and 64.5 ± 4.6 months in the close surveillance group. The recurrence rates did not significantly differ between the 2 groups, at 7.9% in the surgical group and 6.7% in the non-surgical group. CONCLUSIONS Close surveillance may be suggested as an option for EGC patients for whom a surgical approach is difficult, who exhibit a positive vertical margin after ESD, and who have no lymphovascular or deep submucosa invasion after ESD.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) is a widely accepted technique for the management of gastric tumors. However, residual or recurrent tumors can occur after ESD; currently, there is no adequate management strategy for these tumors. Thus, the aim of the present study was to establish a strategy of secondary ESD (sESD) for cases with positive lateral margins (LM+), which cause post-ESD residual or recurrent tumors. METHODS Fifty-three lesions that were subjected to ESD were diagnosed as LM+ with suspected local residual tumor. The short- and long-term outcomes of early sESD (performed shortly after the initial ESD in LM+ cases to prevent local recurrence) were retrospectively compared with those of late sESD (performed after the detection of recurrent tumors). RESULTS Of the 53 LM+ cases, the local residual positive rate was 38.5 % (10/26) in those undergoing early sESD or additional surgery and the local recurrence rate was 29.6 % (8/27) in those that were not treated. Thus, the overall incidence of residual or recurrent tumors in LM+ cases was 34.0 % (18/53). Both early and late sESD had favorable outcomes with no severe complications: 100 % of early sESD resections were curative, compared with 86.7 % of late sESD resections, over the course of a mean (±SD) observation period of 50.8 ± 16.7 months. The performance of early sESD was significantly greater than that of late sESD (in terms of dissection speed). CONCLUSIONS Early sESD is more reliable than late sESD as a therapeutic strategy for salvaging residual tumors and for preventing recurrence. However, if a tumor has already recurred, late sESD remains useful.

Abstract
BACKGROUND Although surgery is recommend for non-curative endoscopic resection of early gastric cancer (EGC), only a part of patients are found to have lymph node (LN) metastasis. This study aimed to identify the predictors of LN metastasis in patients with non-curative endoscopic resection. METHODS Between April 2005 and July 2013, consecutive patients who received non-curative endoscopic resection and then underwent gastrectomy with lymphadenectomy or followed at least 1 year with abdominal computed tomography were retrospectively enrolled at a single tertiary hospital. Non-curative resection was defined as a resection beyond the expanded criteria in pathologic mapping. The predictors for LN metastasis were identified by fitting a multivariate logistic regression model. RESULTS Among the 1783 consecutive patients who received endoscopic resection of EGC, non-curative resection was performed in 323 (18.1%) patients. Of these patients, a total of 267 patients were enrolled, and the rate of LN metastasis was 6.7% (18/267). In multivariate analysis, venous invasion [odds ratio (OR), 7.83; 95% confidence interval (CI) 2.20-27.86; p = 0.001], sm2 invasion (tumor invasion ≥500 µm into submucosa; OR 4.98; 95% CI 1.34-18.47; p = 0.016), or antral tumor location (OR 12.65; 95% CI 1.57-102.00; p = 0.017) were independent predictors for LN metastasis. The rates of LN metastasis were 1.1% (95% CI 0-2.7) for patients with one or no predictor and 17.8% (95% CI 9.7-25.8) for those with two or more predictors. CONCLUSIONS Additional gastrectomy with lymphadenectomy after non-curative endoscopic resection of EGC is recommended for the patients with two or more identified predictors. However, close follow-up without immediate surgery might be considered cautiously for those with only one or no predictor.

Relevant risk factors and prognostic impact of positive resection margins after endoscopic submucosal dissection of superficial esophageal squamous cell neoplasia. Surg Endosc 2014; 28:1653-9. [PMID: 24380990 DOI: 10.1007/s00464-013-3366-9] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2013] [Accepted: 12/03/2013] [Indexed: 02/06/2023]
Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) for the treatment of esophageal mucosal lesions has a risk of resection margin residues. The related risk factors and prognosis of post-ESD resection margin residues have not been fully evaluated. The aim of this study was to investigate the associated risk factors and the prognostic impact of resection margin residues after ESD of superficial esophageal squamous cell neoplasia. METHODS We conducted a retrospective analysis of medical records at our hospital, including the clinical, endoscopic, and pathological data from patients who underwent ESD for the treatment of superficial esophageal squamous cell neoplasia from January 2008 to December 2012. In addition, we conducted a statistical analysis of the following factors: sex, age, location, the proportion of circumferential extension, the maximum diameter of the resected specimen, macroscopic type, the depth of invasion, and the endoscopists. RESULTS A total of 145 patients were included in the study. Overall, 148 lesions were completely resected. There were 17 patients (17 lesions) presenting with positive resection margin after ESD and the positive rate was 11.5 %. A total of 16 patients were followed-up. Among the patients who had resection margin residues, three underwent surgical esophageal resection, one underwent radiotherapy, two received ESD, and one received endoscopic mucosal resection. The remaining nine patients were periodically followed-up, and no recurrences were found. The results of a one-dimensional analysis suggested that there were significant differences in the maximum diameters of the resected specimens, macroscopic type, and the depth of invasion between the positive resection margin group and the negative resection margin group. The results of a multivariate regression analysis suggested that the maximum diameter of the resected specimens and the depth of invasion were risk factors for resection margin residues. CONCLUSIONS The maximum diameter of the resected specimens and the depth of tumor invasion are risk factors for post-ESD positive resection margins, which suggests that larger lesions and a greater depth of invasion increases the chance of residual tumor after ESD.

Abstract
Nowadays, endoscopic mucosal resection or endoscopic submucosal dissection has shown effectiveness equivalent to that of gastrectomy and has emerged as a popular technique for curative treatment of gastric cancer. However, noncurative resection or resection beyond the indication may lead to lymphatic and extended organ metastasis resulting in loss of the opportunity for full recovery. Therefore, it is an important issue to decide the range of curative resection in the endoscopic resection field. Furthermore, management of noncurative endoscopic resection in early gastric cancer is also important. The most favorable treatment after noncurative resection would be surgery. However, other noninvasive treatments such as argon plasma coagulation, additional endoscopic resection and close observation for recurrence are thought to be the optional treatments after the noncurative resection. In the future, prospective research studies and observations are expected to verify the effectiveness of noninvasive treatments.
