A new, simplified endoscopic scoring system for predicting clinical outcome in gastric low-grade intraepithelial neoplasia: the "e-cout system". Neoplasia 2024; 56:101030. [PMID: 39047660 PMCID: PMC11318536 DOI: 10.1016/j.neo.2024.101030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2024] [Revised: 07/08/2024] [Accepted: 07/08/2024] [Indexed: 07/27/2024]
Abstract
BACKGROUND AND OBJECTIVES The clinical outcomes of gastric low-grade intraepithelial neoplasia (LGIN) exhibit significant diversity, and the current reliance on endoscopic biopsy for diagnosis poses limitations in devising appropriate treatment strategies for this disease. This study aims to establish a prognostic prediction scoring system (e-Cout system) for gastric LGIN, offering a theoretical foundation for solving this clinical challenge. METHODS Retrospectively selecting 1013 cases meeting the inclusion and exclusion criteria from over 300,000 cases of upper gastrointestinal endoscopy performed at the Digestive Endoscopy Center of our hospital between 2000 and 2022, the cohort included 484 cases as development cohort and 529 cases for validation. Employing relevant statistical analysis, we used development cohort data to establish the e-Cout system for gastric LGIN, and further used validation cohort data to for internal validation. RESULTS In the developmental stage, based on accordant regression coefficients, we assigned point values to six risk factors for poor prognosis: 4 points for microvessel (MV) distortion, 3 points for MV thickening, 2 points for ulcer, and 1 point each for lesion size > 2cm, disease duration > 1 year, and hyperemia and redness on the lesion surface. Patients were then categorized into four risk levels: low risk (0-1 point), medium risk (2-3), high risk (4-6), and very high risk (≥7). During the validation stage, significant differences in the three different outcomes of gastric LGIN were observed across all risk levels. The probability of reversal and progression showed a significant decrease and increase, respectively, with escalating of risk levels, and these differences were statistically significant (P< 0.001). CONCLUSIONS The proposed e-Cout system holds promise in aiding clinicians to predict the probability and risk levels of different clinical outcomes in patients with gastric LGIN. This system is expected to provide an improved foundation and guidance for the selection of clinical strategies for this disease.

Gastric transcatheter chemoembolization combined with systemic chemotherapy vs. systemic chemotherapy alone for patients with advanced gastric cardiac cancer presenting with dysphagia: A case control study. Oncol Lett 2024; 28:367. [PMID: 38933810 PMCID: PMC11200157 DOI: 10.3892/ol.2024.14500] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2024] [Accepted: 05/17/2024] [Indexed: 06/28/2024] Open
Abstract
The present study aimed to assess the effectiveness of gastric transcatheter chemoembolization (GTC) combined with systemic chemotherapy (SYS) compared with SYS alone in managing dysphagia, and improving the quality of life (QoL) and nutritional status of patients with advanced gastric cardiac cancer (AGCC). A retrospective review was performed using data from consecutive patients with AGCC who experienced dysphagia and underwent either SYS alone or SYS combined with GTC from January 2018 to December 2022. Propensity score matching (PSM) analysis was performed to address potential confounding factors. Ogilvie dysphagia scores were used to assess dysphagia, the Functional Assessment of Cancer Therapy-General 7 (FACT-G7) was used to assess QoL, and the Patient-Generated Subjective Global Assessment (PG-SGA) was used to evaluate nutritional status. After PSM, a total of 228 patients were included in the analysis, with 114 in each group. At 4 and 8 weeks after the initial treatment, the GTC + SYS group demonstrated significantly lower median Ogilvie scores compared with the SYS alone group (P<0.001). Similarly, the median PG-SGA score at 4 weeks after the initial treatment was 2.0 in the GTC + SYS group and 6.0 in the SYS alone group. The median FACT-G7 scores in the GTC + SYS group was 13.0, compared with 10.5 in the SYS alone group. These differences remained significant at 8 weeks (P<0.001). In conclusion, the addition of GTC to SYS may more effectively and promptly relieve dysphagia, improve nutritional status and enhance QoL compared with SYS alone in patients with AGCC presenting with dysphagia.

Abstract
Gastric cancer presents a significant global health burden, as it is the fifth most common malignancy and fourth leading cause of cancer mortality worldwide. Variations in incidence rates across regions underscores the multifactorial etiology of this disease. The overall 5-year survival rate remains low despite advances in its diagnosis and treatment. Although surgical gastrectomy was previously standard-of-care, endoscopic resection techniques, including endoscopic mucosal resection and endoscopic submucosal dissection (ESD) have emerged as effective alternatives for early lesions. Compared to surgical resection, endoscopic resection techniques have comparable 5-year survival rates, reduced treatment-related adverse events, shorter hospital stays and lower costs. ESD also enables en bloc resection, thus affording organ-sparing curative endoscopic resection for early cancers. In this editorial, we comment on the recent publication by Geng et al regarding gastric cystica profunda (GCP). GCP is a rare gastric pseudotumour with the potential for malignant progression. GCP presents a diagnostic challenge due to its nonspecific clinical manifestations and varied endoscopic appearance. There are several gaps in the literature regarding the diagnosis and management of GCP which warrants further research to standardize patient management. Advances in endoscopic resection techniques offer promising avenues for GCP and early gastric cancers.

Abstract
BACKGROUND Whether the Western pT1acN0M0 gastric cancer (GC) patients who met the Japanese expanded criteria could be the candidates for endoscopic treatment (ET) remains unclear because of unknown long-term survival outcomes. METHODS A retrospective cohort study using data from the Surveillance, Epidemiology, and End Results (SEER) program was performed. The survival differences between pT1acN0M0 gastric adenocarcinoma patients who received ET or gastrectomy treatment (GT) were evaluated using multivariate survival analysis. RESULTS A total of 314 pT1acN0M0 gastric adenocarcinoma patients who met the expanded criteria were included, 46 patients received ET and 268 patients received GT. pT1acN0M0 gastric adenocarcinoma patients met the expanded criteria underwent ET experienced a similar hazard of cancer-specific death compared with those underwent GT both in the multivariate Cox survival analysis (adjusted hazard ratio [HR]; 1.18, 95% confidence interval [CI] 0.40-3.49; P = 0.766) and the multivariate competing risk model (subdistribution HR [SHR], 1.12, 95% CI 0.38-3.29; P = 0.845). The result that pT1acN0M0 gastric adenocarcinoma patients met the expanded criteria underwent ET experienced comparable survival outcomes to those who underwent GT did not change even compared with those who underwent GT with > 15 lymph nodes examined (adjusted HR, 1.55, 95% CI 0.44-5.49; P = 0.499; SHR, 1.47, 95% CI 0.44-4.88; P = 0.532). CONCLUSIONS The ET can be considered in Western pT1acN0M0 gastric adenocarcinoma patients who met the Japanese expanded criteria. However, a prospective study should be warranted.

Abstract
Background Malignancies in the upper gastrointestinal tract are amenable to endoscopic resection at an early stage. Achieving a curative resection is the most stringent quality criterion, but post-resection risk assessment and aftercare are also part of a comprehensive quality program. Summary Various factors influence the achievement of curative resection. These include endoscopic assessment prior to resection using chromoendoscopy and HD technology. If resectability is possible, it is particularly important to delineate the lateral resection margins as precisely as possible before resection. Furthermore, the correct choice of resection technique depending on the lesion must be taken into account. Endoscopic submucosal dissection is the standard for esophageal squamous cell carcinoma and gastric carcinoma. In Western countries, it is becoming increasingly popular to treat Barrett's neoplasia over 2 cm in size and/or with suspected submucosal infiltration with en bloc resection instead of piece meal resection. After resection, risk assessment based on the histopathological resection determines the patient's individual risk of lymph node metastases, particularly in the case of high-risk lesions. This is categorized according to the current literature. Key Messages This review presents clinical algorithms for endoscopic resection of esophageal SCC, Barrett's neoplasia, and gastric neoplasia. The algorithms include the pre-resection assessment of the lesion and the resection margins, the adequate resection technique for the respective lesion, as well as the post-resection risk assessment with an evidence-based recommendation for follow-up therapy and surveillance.

Abstract
BACKGROUND AND AIMS Endoscopic submucosal dissection (ESD) is effective in treating early gastric cancer (EGC). Its role in patients with comorbidities along with more advanced disease is unknown. We sought to evaluate this in a large Western cohort. METHODS Consecutive patients who underwent ESD for EGC in a single tertiary Western endoscopy center over 10 years were prospectively analyzed. The primary outcomes were long-term overall survival (OS) and disease-free survival (DFS) up to 5 years. Secondary outcomes were efficacy and serious adverse events (SAEs). RESULTS ESD for 157 cases of EGC in 149 patients was performed in an elderly and comorbid cohort with a mean age of 73.7 years and age-adjusted Charlson Comorbidity Index of 4.2. Over a median follow-up of 51.6 months, no significant differences were found in 5-year OS (88.9% vs 77.9%, P = .290) and DFS (83.2% vs 75.1%, P = .593) between absolute indication (AI) EGC and relative indication (RI) EGC. The AI EGC cohort achieved higher en-bloc (96.3% vs 87.5%, P = .069) and R0 resection rates (93.6% vs 62.5%, P < .001) when compared with RI EGC. No significant differences were found in SAEs (7.3% vs 12.5%, P = .363). No mortality or surgical resection ensued from adverse events from ESD. CONCLUSIONS ESD safely confers DFS in poor surgical candidates with RI EGC in a large Western cohort. Patients who are elderly and/or with comorbidities or decline surgical resection may benefit from ESD and avoid the risks of surgery and its long-term sequelae.

Abstract
BACKGROUND Delayed bleeding (DB) is a possible adverse event following gastric endoscopic submucosal dissection (ESD). The BEST-J score was created as a risk prediction model for DB following gastric ESD, but is yet to be validated in Western populations. AIMS We aimed to validate the BEST-J score on a European sample and to perform a subgroup analysis according to histological classification. METHODS Retrospective study of all consecutive patients undergoing gastric ESD on a European Endoscopic Unit. DB was defined as hemorrhage with clinical symptoms and confirmed by emergency endoscopy from the time of completion to 28 days after ESD. BEST-J score was calculated in each patient and confronted with the outcome (DB). RESULTS Final sample included 161 patients. From these, 10 (6.2%) presented DB following ESD, with a median time to bleeding of 7 days (IQR 6.8). BEST-J score presented an excellent accuracy predicting DB in our sample, with an AUC = 0.907 (95%CI 0.801-1.000; p < 0.001). Subgroup analysis by histological classification proved that the discriminative power was still excellent for each grade: low-grade dysplasia-AUC = 0.970 (p < 0.001); high-grade dysplasia-AUC = 0.874 (p < 0.001); early gastric cancer-AUC = 0.881 (p < 0.001). The optimal cut-off value to predict DB was a BEST-J score ≥ 3, which matches the cut-off value for high-risk of bleeding in the original investigation. CONCLUSIONS The BEST-J score still presents excellent accuracy in risk stratification for post-ESD bleeding in European individuals. Thus, this score may help to guide which patients benefit the most from prophylactic therapies following gastric ESD in this setting.

The effect of short-term training about depth predicting score on the diagnostic ability of invasion depth for differentiated early gastric Cancer among non-expert endoscopists. BMC MEDICAL EDUCATION 2023; 23:347. [PMID: 37198569 DOI: 10.1186/s12909-023-04230-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Accepted: 04/03/2023] [Indexed: 05/19/2023]
Abstract
BACKGROUND The depth-predicting score (DPS) was proposed based on conventional white-light imaging (C-WLI) endoscopic features of early gastric cancer (EGC) to determine the invasion depth of the neoplasm. However, the effect of DPS on training endoscopists remains unclear. Therefore, we aimed to investigate the effect of short-term DPS training on improving the diagnostic ability of EGC invasion depth and compare the training effect among non-expert endoscopists at different levels. METHODS In the training session, the definitions and scoring rules of DPS were instructed, and classic C-WLI endoscopic example graphics were exhibited to the participants. Another C-WLI endoscopic images of 88 cases of histologically proven differentiated EGC were selected as an independent test dataset for evaluating the training effect. Each participant was tested, and the diagnostic accuracy rate of invasion depth was calculated differently one week before the training and after the completion of training. RESULTS A total of 16 participants were enrolled and completed the training. Participants were divided into a trainee group and a junior endoscopist group according to the total number of C-WLI endoscopies performed. The total number of C-WLI endoscopies performed showed a significant difference between the trainee group and junior endoscopist group (350 vs. 2500, P = 0.001). No significant difference between the trainee group and junior endoscopist group was observed for pre-training accuracy. The overall diagnostic accuracy of invasion depth was improved significantly after completing DPS training compared with before (68.75 ± 5.71% vs. 61.58 ± 9.61%, P = 0.009). In the subgroup analysis, the post-training accuracy was higher than the pre-training accuracy, but significant improvement was observed only in the trainee group (61.65 ± 7.33% vs. 68.32 ± 5.71%, P = 0.034). In addition, no significant difference in post-training accuracy between the two groups was observed. CONCLUSION Short-term DPS training can improve the diagnostic ability of the invasion depth of EGC and homogenize the diagnostic ability of non-expert endoscopists at different levels. The depth-predicting score was convenient and effective for endoscopist training.

Predictive factors of lymphatic metastasis and evaluation of the Japanese treatment guidelines for endoscopic resection of early gastric cancer in a high-volume center in Perú. Heliyon 2023; 9:e16293. [PMID: 37251889 PMCID: PMC10209413 DOI: 10.1016/j.heliyon.2023.e16293] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2022] [Revised: 05/10/2023] [Accepted: 05/11/2023] [Indexed: 05/31/2023] Open
Abstract
Purpose This study aimed to identify the predictive factors of lymph node metastasis (LNM) in patients with early gastric cancer (EGC) and to evaluate the applicability of the Japanese treatment guidelines for endoscopic resection in the western population. Methods Five hundred-one patients with pathological diagnoses of EGC were included. Univariate and multivariate analyses were conducted to identify the predictive factors of LNM. EGC patients were distributed according to the indications for endoscopic resection of the Eastern guidelines. The incidence of LNM was evaluated in each group. Results From 501 patients with EGC, 96 (19.2%) presented LNM. In 279 patients with tumors with submucosal infiltration (T1b), 83 (30%) patients had LNM. Among 219 patients who presented tumors > 3 cm, 63 (29%) patients had LNM. Thirty-one percent of patients with ulcerated tumors presented LMN (33 out of 105). In 76 patients and 24 patients with lymphovascular and perineural invasion, the percentage of LMN was 84% and 87%, respectively. In the multivariate analysis, a tumor diameter >3 cm, submucosal invasion, lymphovascular, and perineural invasion were independent predictors of LMN in EGC. No patient with differentiated, non-ulcerated mucosal tumors presented LNM regardless of tumor size. Three of 17 patients (18%) with differentiated, ulcerated mucosal tumors and ≤ 3 cm presented LNM. No LNM was evidenced in patients with undifferentiated mucosal tumors and ≤ 2 cm. Conclusions The presence of LNM in Western EGC patients was independently related to larger tumors (>3 cm), submucosal invasion, lymphovascular and perineural invasion. The Japanese absolute indications for EMR are safe in the Western population. Likewise, Western patients with differentiated, non-ulcerated mucosal tumors, and larger than 2 cm are susceptible to endoscopic resection. Patients with undifferentiated mucosal tumors smaller than 2 cm presented encouraging results and ESD could be recommended only for selected cases.

Abstract
INTRODUCTION Endoscopic resection (ER) of early gastric cancer (EGC) is increasingly used in Eastern countries due to their low rates of lymph node metastasis (LNM); however, there is a paucity of evidence in Western countries. We investigated LNM and its effect on overall survival (OS) in Western patients with EGC. METHODS Patients diagnosed with T1 gastric cancer between 2000 and 2017 were retrospectively evaluated. Univariate Kaplan-Meier, multivariate logistic and Cox-regression models were used to assess the associations between clinical characteristics, LNM, and OS. RESULTS Among 86 patients, median age was 68 years and 72% were male. Node positivity was 30%. Two percent of patients met the classical guidelines for ER and all were node-negative, while 16% met expanded criteria of which 14% were node-positive. T1b disease (odds ratio [OR] 41.2 [95% confidence interval [CI] 1.62-1048], p = 0.02) and lymphovascular/perineural invasion (OR 18.0 [95% CI 2.41-134], p = 0.01) were predictive of node positivity. The 5-year OS for node-negative and node-positive patients was 84% and 53% (p = 0.004), respectively. CONCLUSIONS The risk of LNM in Western patients with EGC is higher; therefore, generalizability of the expanded criteria for ER should be interpreted with caution.

Abstract
BACKGROUND Vonoprazan is a potassium competitive acid blocker (P-CAB) approved in Japan in 2014 to treat endoscopic submucosal dissection (ESD)-induced ulcers and bleeding or perforation. Therefore, this meta-analysis aimed to determine whether Vonoprazan is more effective than Lansoprazole in the treatment of ESD-induced ulcers which include ulcer healing and shrinking rate, among others. METHODS Randomized controlled trials (RCT) and retrospective studies were collected from the PubMed (Medline), Embase, Web of science and Cochrane Library databases. Meanwhile, studies were selected according to predetermined qualification criteria and data were extracted by two researchers. The quality of the methods for published papers was evaluated using the modified Jadad scale. RESULTS Five studies were included in this meta-analysis, the ulcer healing rate effect was not significantly higher in the intervention groups than in the control groups at 4 weeks, [OR:1.07 (0.51, 2.22), 95% CI, I2=2%, Z=0.18, P=0.86]. There was no significant difference in the ulcer shrinkage rate at 4 weeks [MD:0.20 (-1.51, 1.92), 95% CI, I2=0%, P=0.82] and 8 weeks [MD: -0.09 (-0.30, 0.12), 95% CI, I2=0%, P=0.39]. CONCLUSION There was no significant difference between Vonoprazan and Lansoprazole in the ulcers induced by treatment after 4 weeks and 8 weeks of treatment with ESD.

Abstract
BACKGROUND & AIMS We aimed to clarify the long-term outcomes of endoscopic resection (ER) for early gastric cancers (EGCs) based on pathological curability in a multicenter prospective cohort study. METHODS We analyzed the long-term outcomes of 9054 patients with 10,021 EGCs undergoing ER between July 2010 and June 2012. Primary endpoint was the 5-year overall survival (OS). The hazard ratio for all-cause mortality was calculated using the Cox proportional hazards model. We also compared the 5-year OS with the expected one calculated for the surgically resected patients with EGC. If the lower limit of the 95% confidence interval (CI) of the 5-year OS exceeded the expected 5-year OS minus a margin of 5% (threshold 5-year OS), ER was considered to be effective. Pathological curability was categorized into en bloc resection, negative margins, and negative lymphovascular invasion: differentiated-type, pT1a, ulcer negative, ≤2 cm (Category A1); differentiated-type, pT1a, ulcer negative, >2 cm or ulcer positive, ≤3 cm (Category A2); undifferentiated-type, pT1a, ulcer negative, ≤2 cm (Category A3); differentiated-type, pT1b (SM1), ≤3 cm (Category B); or noncurative resections (Category C). RESULTS Overall, the 5-year OS was 89.0% (95% CI, 88.3%-89.6%). In a multivariate analysis, no significant differences were observed when the hazard ratio of Categories A2, A3, and B were compared with that of A1. In all the pathological curability categories, the lower limit of the 95% CI for the 5-year OS exceeded the threshold 5-year OS. CONCLUSION ER can be recommended as a standard treatment for patients with EGCs fulfilling Category A2, A3, and B, as well as A1 (UMIN Clinical Trial Registry, UMIN000005871).

Abstract
Background Endoscopic submucosal dissection (ESD) has been accepted as the standard treatment for the appropriate indication of early gastric cancer (EGC). Determining the risk of lymph node metastasis (LNM) is critical for the following treatment selection after ESD. This study aimed to develop a predictive model to quantify the probability of LNM in EGC to help minimize the invasive procedures. Methods A total of 952 patients with EGC who underwent radical gastrectomy were retrospectively reviewed. LASSO regression was used to help screen the potential risk factors. Multivariate logistic regression was used to establish a predictive nomogram, which was subjected to discrimination and calibration evaluation, bootstrapping internal validation, and decision curve analysis. Results Results of multivariate analyses revealed that gender, fecal occult blood test, CEA, CA19-9, histologic differentiation grade, lymphovascular invasion, depth of infiltration, and Ki67 labeling index were independent prognostic factors for LNM. The nomogram had good discriminatory performance, with a concordance index of 0.816 (95% CI 0.781–0.853). The validation dataset yielded a corrected concordance index of 0.805 (95% CI 0.770–0.842). High agreements between ideal curves and calibration curves were observed. Conclusions The nomogram is clinically useful for predicting LNM after ESD in EGC, which is beneficial to identifying patients who are at low risk for LNM and would benefit from avoiding an unnecessary gastrectomy.

Abstract
BACKGROUND AND AIMS Studies evaluating the role of endoscopic submucosal dissection (ESD) in the management of superficial pharyngeal cancers have reported promising results. This meta-analysis evaluates the efficacy and safety of ESD in the management of superficial pharyngeal cancers. METHODS We reviewed several databases from inception to September 03, 2020, to identify studies evaluating the efficacy and safety of ESD in the management of superficial pharyngeal cancers. Our outcomes of interest were en bloc resection rate, complete resection rate, adverse events, and rates of local recurrence. Pooled rates with 95% confidence intervals (CI) for all outcomes were calculated using random-effect model. Heterogeneity was assessed by I2 statistic. We assessed publication bias by using funnel plots and Egger's test. We conducted meta-regression analysis to explore heterogeneity in analyses. RESULTS Ten studies were included in analyses. All studies were from Asia. Pooled rates (95% CI) for en bloc resection and complete resection were 94% (87%, 97%) and 72% (62%, 80%), respectively. The pooled rates (95% CI) for adverse events and local recurrence were 10% (5%, 17%) and 1.9% (0.9%, 4%), respectively. Most of the analyses were limited by substantial heterogeneity. On meta-regression analysis, the heterogeneity was explained by size of tumor and histology. Funnel plots and Egger's test showed no evidence of publication bias. CONCLUSIONS This meta-analysis including studies from Asian countries demonstrated that ESD is an efficacious and safe option in the management of superficial pharyngeal cancers. More studies and studies from Western countries are needed to further validate these findings.

Abstract
BACKGROUND Endoscopic treatment of precancerous lesions and early gastric cancer has been widely accepted in recent years. Endoscopic submucosal dissection (ESD), following established indication criteria, can lead to cure of the disease in more than 90% of cases. OBJECTIVE This study aimed to analyze the use of ESD in patients with early gastric cancer and precancerous lesions, as well as the results of the procedure, its complications and effectiveness in controlling the disease. METHODS This is a retrospective cohort study composed of 41 patients aged from 53 to 87 years (mean age: 65 years; 58.53% male) who were analyzed from 2008 to 2019. The variables collected from the medical records were: comorbidities, classification of the lesion regarding resection criteria, type of resection, histology, degree of invasion, resection margin, complications, disease recurrence. Statistical analysis was performed using the Kruskal-Wallis test, the McNemar's test, and the Mann-Whitney test, with 5% statistical significance (P<0.05). RESULTS The most frequent site of the lesion was the gastric antrum and the predominant presentation by the Japanese or Paris classification was the one with depressed components in 56.09%. Adenocarcinoma occurred in 75.6% of the biopsies, and the remainder were adenomas without neoplasia. En-bloc resection occurred in 97.57% of cases, and compromise of the safety margin occurred in one patient. The main pre-existing comorbidity was liver cirrhosis in 29.26% of cases. There was a significant increase in post- ESD adenocarcinoma compared to pre-resection diagnosis. The mean follow-up time was 38.4 months, with one recurrence (2.43%) and two metachronous lesions (4.87%). Complications during and after the procedure occurred in three patients (7.31%), being due to bleeding (two cases) and perforation (one case). There was one death due to a cardiac event not directly related to the procedure. CONCLUSION Endoscopic submucosal dissection proved to be a safe procedure, with a low complication and recurrence rate. Its recommendation must occur within the established criteria; however, it can be indicated for patients outside the criteria, if there is a high risk for surgical treatment.

Abstract
Objective This study aimed to systematically evaluate the diagnostic performance of double contrast-enhanced ultrasonography (DCEUS) in the preoperative T staging of gastric cancer (GC). Methods Literature searches for eligible studies were performed using MEDLINE, EMBASE, and Cochrane Library. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio, and area under the summary receiver operating characteristic curve of DCEUS in the diagnosis of each T stage tumor were calculated. Meta-analyses were performed to obtain the pooled effects of risk ratio (RR) with 95% confidence interval (CI) in the comparison of DCEUS with CT/endoscopic ultrasound (EUS). Results A total of 8 studies including 1,232 patients were identified for inclusion in this meta-analysis. The pooled sensitivity and specificity were 0.78 (95% CI = 0.64–0.88) and 0.98 (95% CI = 0.96–0.99) for T1, 0.81 (95% CI = 0.76–0.86) and 0.96 (95% CI = 0.91–0.98) for T2, 0.88 (95% CI = 0.84–0.91) and 0.85 (95% CI = 0.79–0.90) for T3, and 0.81 (95% CI = 0.69–0.89) and 0.96 (95% CI = 0.93–0.97) for T4. Moreover, DCEUS demonstrated significant superiority to CT in diagnosing T1 (RR = 1.57, 95% CI = 1.20–2.05, p = 0.001) and T2 (RR = 1.41, 95% CI = 1.16–1.71, p = 0.001) and to EUS in diagnosing T3 (RR = 1.24, 95% CI = 1.08–1.42, p = 0.003) and T4 (RR = 1.40, 95% CI = 1.09–1.79, p = 0.008). However, it showed a lower diagnostic accuracy than EUS in T1 tumors (RR = 0.77, 95% CI = 0.62–0.94, p = 0.013). Conclusions DCEUS is a feasible complementary diagnostic tool for clinical T staging of GC. However, it is still far from a definitive conclusion for DCEUS to be proposed for use in routine clinical practice.

Santos-Antunes J, Marques M, Morais R, Carneiro F, Macedo G. Colorectal Endoscopic Submucosal Dissection in a Western Center: Analysis of Outcomes and Safety Profile. GE-PORTUGUESE JOURNAL OF GASTROENTEROLOGY 2021; 28:319-327. [PMID: 34604463 DOI: 10.1159/000514797] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Accepted: 01/22/2021] [Indexed: 11/19/2022]
Abstract
Introduction Endoscopic submucosal dissection (ESD) is a well-established endoscopic technique for the treatment of gastrointestinal lesions. Colorectal ESD outcomes are less reported in the Western literature, and Portuguese data are still very scarce. Our aim was to describe our experience on colorectal ESD regarding its outcomes and safety profile. Methods We conducted a retrospective evaluation of recorded data on ESDs performed between 2015 and 2020. Only ESDs performed on epithelial neoplastic lesions were selected for further analysis. Results Of a total of 167 colorectal ESDs, 153 were included. Technical success was achieved in 147 procedures (96%). The lesions were located in the colon (n = 24) and rectum (n = 123). The en bloc resection rate was 92% and 97%, the R0 resection rate was 83% and 82%, and the curative resection rate was 79% and 78% for the colon and the rectum, respectively. The need for a hybrid technique was the only risk factor for piecemeal or R1 resection. We report a perforation rate of 3.4% and a 4.1% rate of delayed bleeding; all the adverse events were manageable endoscopically, without the need of blood transfusions or surgery. Most of the lesions were laterally spreading tumours of the granular mixed type (70%), and 20% of the lesions were malignant (12% submucosal and 8% intramucosal cancer). Conclusion Our series on colorectal ESD reports a very good efficacy and safety profile. This technique can be applied by endoscopists experienced in ESD.

J Gastroenterol Hepatol 2021; 36:2813-2818. [PMID: 34022773 DOI: 10.1111/jgh.15552] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2021] [Revised: 05/13/2021] [Accepted: 05/19/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND AIMS Endoscopic submucosal dissection (ESD) is the recommended treatment for early gastric cancer (EGC). However, there are challenges in attaining expertise in ESD in countries where the incidence of gastric cancer and proportion diagnosed at an early stage of disease are relatively low. This study aims to establish the proportion of gastric cancer meeting histological criteria for EGC, which may be suitable for ESD, in a Western population. METHODS Gastric cancers reported to the Victorian Cancer Registry between January 2011 and December 2016 were analyzed. EGC was defined as tumor confined to mucosa (T1a) or submucosa (T1b). Histology reports were analyzed using Japanese and European guidelines to identify potential ESD candidates. Criteria for extended ESD were based on grade of differentiation, tumor depth, lymphovascular and perineural invasion, and ulceration. RESULTS Twenty percent of 1217 gastric cancers was EGC (237 cases), with detailed histopathology reports suitable for evaluating ESD criteria recorded in 182 cases. Standard and extended ESD criteria were met in 46% (84/182) and 75% (132/182), respectively. Actual treatment of the 237 EGC was endoscopic in 14% (n = 33) and surgery in 86% (n = 204). Endoscopically treated EGCs were more likely to be stage T1a and located in the proximal stomach. CONCLUSIONS EGCs represented 20% of reported gastric adenocarcinomas with the majority fulfilling criteria for ESD. ESD should be considered in the management algorithm and discussed at tumor board meetings involving interventional endoscopists. To increase utilization of ESD, systems need to be implemented to improve training, accreditation, and access to ESD.

Abstract
Gastric cancer accounts for a significant proportion of worldwide cancer-related morbidity and mortality. The well documented precancerous cascade provides an opportunity for clinicians to detect and treat gastric cancers at an endoscopically curable stage. In high prevalence regions such as Japan and Korea, this has led to the implementation of population screening programs. However, guidelines remain ambiguous in lower prevalence regions. In recent years, there have been many advances in the endoscopic diagnosis and treatment of early gastric cancer and precancerous lesions. More advanced endoscopic imaging has led to improved detection and characterization of gastric lesions as well as superior accuracy for delineation of margins prior to resection. In addition, promising early data on artificial intelligence in gastroscopy suggests a future role for this technology in maximizing the yield of advanced endoscopic imaging. Data on endoscopic resection (ER) are particularly robust in Japan and Korea, with high rates of curative ER and markedly reduced procedural morbidity. However, there is a shortage of data in other regions to support the applicability of protocols from these high prevalence countries. Future advances in endoscopic therapeutics will likely lead to further expansion of the current indications for ER, as both technology and proceduralist expertise continue to grow.

Abstract
BACKGROUND & AIMS Endoscopic submucosal dissection (ESD) is a widely accepted treatment option for superficial gastric neoplasia in Asia, but there are few data on outcomes of gastric ESD from North America. We aimed to evaluate the safety and efficacy of gastric ESD in North America. METHODS We analyzed data from 347 patients who underwent gastric ESD at 25 centers, from 2010 through 2019. We collected data on patient demographics, lesion characteristics, procedure details and related adverse events, treatment outcomes, local recurrence, and vital status at the last follow up. For the 277 patients with available follow-up data, the median interval between initial ESD and last clinical or endoscopic evaluation was 364 days. The primary endpoint was the rate of en bloc and R0 resection. Secondary outcomes included curative resection, rates of adverse events and recurrence, and gastric cancer-related death. RESULTS Ninety patients (26%) had low-grade adenomas or dysplasia, 82 patients (24%) had high-grade dysplasia, 139 patients (40%) had early gastric cancer, and 36 patients (10%) had neuroendocrine tumors. Proportions of en bloc and R0 resection for all lesions were 92%/82%, for early gastric cancers were 94%/75%, for adenomas and low-grade dysplasia were 93%/ 92%, for high-grade dysplasia were 89%/ 87%, and for neuroendocrine tumors were 92%/75%. Intraprocedural perforation occurred in 6.6% of patients; 82% of these were treated successfully with endoscopic therapy. Delayed bleeding occurred in 2.6% of patients. No delayed perforation or procedure-related deaths were observed. There were local recurrences in 3.9% of cases; all occurred after non-curative ESD resection. Metachronous lesions were identified in 14 patients (6.9%). One of 277 patients with clinical follow up died of metachronous gastric cancer that occurred 2.5 years after the initial ESD. CONCLUSIONS ESD is a highly effective treatment for superficial gastric neoplasia and should be considered as a viable option for patients in North America. The risk of local recurrence is low and occurs exclusively after non-curative resection. Careful endoscopic surveillance is necessary to identify and treat metachronous lesions.

Abstract
Background and study aims The goal of this study was to assess surgical resection (SR) of early gastric cancer (EGC) fitting Japanese Gastric Cancer Association (JGCA) endoscopic resection (ER) criteria. Patients and methods We analyzed EGC data from the national Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2015. Results A total of 2219 EGC cases were identified (1074 T1a and 1145 T1b). Of them, 409 met absolute criteria, 219 met expanded 1, 529 expanded 2, and 229 expanded 3. 259 lesions were treated endoscopically while 1007 were surgically resected (20.5 % vs 79.5 %, P = 0.0001). Temporal analysis showed that the frequency of ER steadily increased while SR proportionally decreased during the study period. Cox proportion regression analysis adjusting for confound variables (including age, gender, and race) showed no significant difference in the risk of mortality following either surgery or endoscopy. Conclusions EGC can be safely treated with ER. However, EGC meeting JGCA ER criteria is largely treated with SR in the United States.

Abstract
Introduction Endoscopic submucosal dissection (ESD) has become the treatment of choice for early gastric malignancies. In recent years, the ESD technique has been implemented in Western countries with increasing use. Objectives To describe the results of gastric ESD in a Western country with a low incidence of gastric cancer. Patients and Methods The prospective national registry was conducted over 4 years in 23 hospitals, including 30 endoscopists. Epithelial and subepithelial lesions (SEL) qualified to complete removal with ESD were assessed. The technique, instruments, and solution for submucosal injection varied at the endoscopist's discretion. ESD was defined as difficult when: en‐bloc resection was not achieved, had to be converted to a hybrid resection, lasted more than 2 h or an intraprocedural perforation occurred. Additionally, independent risk factors for difficult ESD were analyzed. Results Two hundred and thirty gastric ESD in 225 patients were performed from January 2016 to December 2019 (196 epithelial and 34 SEL). Most lesions were located in the lower stomach (111; 48.3%). One hundred and twenty‐eight (55.6%) ESD were considered difficult. The median procedure time was 105 min (interquartile range [IQR]: 60–150). The procedure time for SEL was shorter than for epithelial lesions (90 min [45–121] vs. 110 min [62–160]; p = 0.038). En‐bloc, R0, and curative resection rates were 91.3%, 75.2%, and 70.9%, respectively. Difficult ESD had lower R0 resection rates than ESD that did not meet the difficulty criteria (64.8% and 87.6%; p = 0.000, respectively). Fibrosis and poor maneuverability were independent factors associated with difficult ESD (OR 3.6, 95%CI 1.1–11.74 and OR 5.07, 95%CI 1.6–16.08; respectively). Conclusions Although the number of cases is limited, the results of this analysis show acceptable en‐bloc and R0 rates in gastric ESD considering the wide variability in experience among the operators. Fibrosis and poor maneuverability were associated with more difficulty in completing ESD. Summarize the established knowledge on this subjectEndoscopic submucosal dissection (ESD) is the standard of care for treatment of early gastric cancers (GC). Due to a lower incidence of GC in European countries, the introduction of gastric ESD has been more gradual than in the East. ESD complications, technical and clinical success depend on the endoscopist's experience, the presence of submucosal fibrosis or invasive cancer, and poor access location.
What are the significant and/or new findings of this study?This study shows the results from a prospective nationwide registry of gastric ESD in a low GC incidence country. Despite a relative low number of cases, quite acceptable outcomes (en‐bloc, R0 and curative resection of 91.3%, 75.2% and 70.9%, respectively) were observed considering the wide variability in experience among the operators. Difficult ESD were mainly associated with the presence of submucosal fibrosis and poor maneuverability; however, independent pre‐procedural factors were not identified. There was a trend of association between ESD difficulty and the location of the lesion in the upper/middle stomach

Abstract
INTRODUCTION AND AIMS Endoscopic submucosal dissection (ESD) in the treatment of superficial neoplasias of the gastrointestinal tract is currently one of the greatest advances in therapeutic endoscopy. Due to its high technical complexity, it is not yet a routine procedure in Latin America. The aim of the present study was to present the experience in Brazil with ESD in superficial gastric neoplasias, based on training received from Japanese experts. MATERIALS AND METHODS A retrospective study was conducted, in which information was prospectively collected from a database that included all patients that underwent ESD due to superficial gastric neoplasias at two endoscopy referral centers in Brazil, within the time frame of June 2008 to June 2019. En bloc, complete, and curative resection rates were calculated, along with the local recurrence rate and adverse events. RESULTS A total of 103 ESDs for superficial gastric neoplasias were performed during the study period. Eighty of those patients (77.6%) presented with early malignant gastric neoplasias or premalignant lesions (adenocarcinoma: 52.5%, high-grade dysplasia: 27.5%, low-grade dysplasia: 16.3%, and neuroendocrine tumors: 3.8%). Overall en bloc and complete resection rates for the superficial gastric neoplasias were 96.3% and 92.5%, respectively, whereas the curative resection rate based on expanded criteria was 76%. CONCLUSIONS ESD for the treatment of superficial gastric neoplasias is a safe and effective therapeutic modality in Latin America, with results similar to those shown in the most representative Japanese studies.

Abstract
Vonoprazan is a potent inhibitor of gastric acid secretion and may have better response than proton pump inhibitors (PPIs) in the treatment of endoscopic submucosal dissection induced artificial ulcers. However, reported outcomes remain controversial. In this study, we conducted a prospective, randomized comparative trial to evaluate healing effects of vonoprazan and lansoprazole on endoscopic submucosal dissection (ESD)-induced ulcers. We enrolled 216 patients who underwent endoscopic submucosal dissection for early gastric neoplasms. They were randomly divided into vonoprazan (20 mg/day) and lansoprazole (30 mg/day) groups. The primary endpoint was the reduction rate of ulcer and complete healing (scar) ratio of ESD-induced ulcers at 4 and 8 weeks. Finally, 101 patients of the vonoprazan group and 95 patients of the lansoprazole group were included in the analysis. There were no significant differences in the reduction rate between the vonoprazan and lansoprazole groups at either timepoint (4 weeks, 94.0 vs 93.4%; 8 weeks, 99.8 vs 99.9%, respectively). The complete healing ratio at 4 and 8 weeks did not differ significantly between the vonoprazan and lansoprazole groups (4 weeks, 11.9 vs 12.6%; 8 weeks, 87.1 vs 86.3%, respectively). In the anti-H. pylori-antibody negative or positive patients, there were no significant differences in the reduction rate and complete healing ratio between the vonoprazan and lansoprazole groups. Regardless of treatment choice, the overall complete healing ratio at 8 weeks was significantly higher in the anti-H. pylori-antibody negative patients than the positive patients (p = 0.006). The healing effects of vonoprazan on ESD-induced ulcers were comparative to those of lansoprazole.

Clinical outcomes of early gastric cardiac cancer treated with endoscopic submucosal dissection in patients with different indications. BMC Gastroenterol 2021; 21:119. [PMID: 33711944 PMCID: PMC7953789 DOI: 10.1186/s12876-021-01700-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Accepted: 03/01/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) has been accepted as a standard treatment for early gastric cardiac cancer (EGCC). Here, we investigate the clinical outcomes of the EGCC patients who underwent ESD in different indications. METHODS From January 2011 to October 2019, we enrolled 502 EGCC lesions from 495 patients which were resected by ESD at our center. We retrospectively analyzed the short-term and long-term clinical outcomes among different indication groups. RESULTS The number of the patients in the absolute indication (AI), expanded indication (EI) and beyond the expanded indication (BEI) groups was 265, 137 and 93, respectively. The en bloc resection rate was 100%, 100% and 98.9% (P = 0.185). The complete resection rate was 99.3%, 98.5% and 74.5%, respectively (P < 0.001). During a median follow-up of 48.1 months, the lymph node metastasis rate was 0%, 0% and 2.3% (P < 0.001). The distant metastasis rate was 0.4%, 0% and 2.3% (P = 0.150). The five-year disease-specific survival rate in the BEI group was 96.6% (P = 0.016), compared to 99.6% in the AI group and 100% in the EI group. CONCLUSION The efficacy for ESD patients in EI group was almost equal to the AI group. Patients in the BEI group showed generally favorable clinical outcomes and needed to be carefully checked after ESD. ESD may be an optional treatment for patients unsuitable for gastrectomy.

Abstract
BACKGROUND & AIMS Endoscopic screening for gastric cancer is routine in some countries with high incidence and is associated with reduced gastric cancer-related mortality. Immigrants from countries of high incidence to low incidence of gastric cancer retain their elevated risk, but no screening recommendations have been made for these groups in the United States. We aimed to determine the cost effectiveness of different endoscopic screening strategies for noncardia gastric cancer, compared with no screening, among Chinese, Filipino, Southeast Asian, Vietnamese, Korean, and Japanese Americans. METHODS We generated a decision-analytic Markov model to simulate a cohort of asymptomatic 50-year-old Asian Americans. The cost effectiveness of 2 distinct strategies for endoscopic gastric cancer screening was compared with no screening for each group, stratified by sex. Outcome measures were reported in incremental cost-effectiveness ratios (ICERs), with a willingness-to-pay threshold of $100,000/quality-adjusted life-year (QALY). Extensive sensitivity analyses were performed. RESULTS Compared with performing no endoscopic gastric cancer screening, performing a 1-time upper endoscopy with biopsies, with continued endoscopic surveillance if gastric intestinal metaplasia was identified, was cost effective, whereas performing ongoing biennial endoscopies, even for patients with normal findings from endoscopy and histopathology, was not. The lowest ICERs were observed for Chinese, Japanese, and Korean Americans (all <$73,748/QALY). CONCLUSIONS Endoscopic screening for gastric cancer with ongoing surveillance of gastric preneoplasia is cost effective for Asian Americans ages 50 years or older in the United States. The lowest ICERs were for Chinese, Japanese, and Korean Americans (all <$73,748/QALY).

Abstract
INTRODUCTION Endoscopic submucosal dissection (ESD) is a well-established procedure that can provide curative resection of malignant and premalignant lesions endoscopically, thereby offering patients an effective non-operative option. Though ESD is safe and highly effective when performed in appropriately selected patients by an experienced ESD expert, it carries risks including intraprocedural and delayed perforation. AREAS COVERED This review provides a practical approach to the initial management of perforation to minimize subsequent complications. The importance of prompt recognition of perforation and early intervention cannot be overstated. This review summarizes indications for closure, anatomic considerations impacting closure, and closure techniques. This article also highlights the do's and don'ts of various closure devices, focusing particularly on advanced closure methods, the-over-the-scope clips (OTSCs) and endoscopic suturing. EXPERT OPINION As ESD offers surgery-sparing alternatives to patients, advanced closure techniques allow endoscopists to effectively and promptly manage associated complications, improving the possibility of the widespread implementation of ESD in the US. With continued improvements in OTSCs and endoscopic suturing, ESD will become a stalwart of endoscopic management of malignant and premalignant gastrointestinal lesions.

Abstract
BACKGROUND AND AIMS Recent studies show promise for endoscopic submucosal dissection (ESD) in the US, but do not identify the potential impact of ESD among newly diagnosed gastric cancers. We utilize the Veterans Health Administration to identify cancers suitable for ESD, to define the role of ESD in the US. METHODS Retrospective cohort study using the Veterans Affairs Central Cancer Registry to identify patients with gastric cancer who underwent surgical resection from 1995-2018. TNM stage was used to categorize those who would meet absolute vs expanded indications for ESD. Primary outcome was lymph node status. Secondary analysis was performed with death as outcome. RESULTS Of 12,584 primary gastric cancers, 4,735 (37.6%) were non-metastatic gastric adenocarcinomas. Median age at diagnosis was 70.3 years, 4,676 (98.8%) male. 2,306 (48.7%) underwent surgical resection, of which 636 (27.6%) were T1 lesions or cancer in situ. Of these, 44 (6.9%) met absolute indications for resection, 99 (15.6%) met established expanded criteria, and 98 (15.4%) may meet expanded criteria. Half of all tumors in each group were proximal in location.Rate of lymph node positivity was: 4.5%; 95% CI:0.5-15.5% in absolute group; 8.1%; 95% CI:3.6-15.3% in expanded group; 13.3%; 95% CI:7.3-21.6 in those potentially meeting expanded criteria. Lymph nodes positivity was associated with death (HR 1.49; 95% CI:1.36-1.62, p<0.001). CONCLUSIONS Less than 10% of T1 or in situ cancers meet absolute criteria for ESD. Those that meet expanded criteria had higher risk for lymph node metastases, particularly proximal tumors. Future studies should evaluate the safety of ESD in proximal gastric tumors.

Accuracy of the revised Vienna Classification for predicting postendoscopic resection outcomes for gastric and oesophageal neoplasms: a retrospective cohort study of patients from a UK tertiary referral centre. J Clin Pathol 2020; 73:493-501. [PMID: 31959615 DOI: 10.1136/jclinpath-2019-206285] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2019] [Revised: 12/22/2019] [Accepted: 12/23/2019] [Indexed: 02/06/2023]
Abstract
AIMS To review the effectiveness of the revised Vienna classification (rVC) at predicting histological outcome and defining the postendoscopic resection (ER) clinical management plan of gastro-oesophageal dysplasia and early neoplasia in a UK tertiary-centre population. METHODS This was a retrospective cohort study between November 2011 and May 2018. 157 patients from Salford Royal NHS Foundation Trust in the UK were included. The primary outcome was the histological results of postsurgical resection (SR) specimens compared with their post-ER rVC. The secondary outcome was overall survival rates of patients with category 4.4 and 5 of the rVC. RESULTS One-hundred and thirteen patients were diagnosed with category ≥4 of the rVC. 23 patients (20.4%) were referred for additional surgery, whereas 69 patients (61.1%) were on endoscopic surveillance only. 60.9% of post-SR specimens (14/23) revealed no residual neoplasia. 78.6% of these cancer-free specimens were classed as category 5 rVC. The overall 7-year survival rate of 25 patients with category ≥4.4 was 68% with causes of mortality not linked to upper gastrointestinal neoplasia. The overall 7-year and 3-year survival rates of category 4.4 and 5 were 73.6% and 50%, respectively, although age and comorbid state played a role. CONCLUSIONS This study provides evidence of outcomes comparable to other reported cohorts for cases after ER in a single-centre UK population even at rVC 4.4/5. It suggests surgery may not be necessary in all cases due to the lack of residual disease and further refinement of the rVC category 5 may help guide management.
