Abstract
This study evaluated the clinical characteristics of multiple early gastric cancer (MEGC) and high-grade intraepithelial neoplasia (HGIN) treated by endoscopic submucosal dissection. The clinical profiles of 23 patients with MEGC treated by endoscopic submucosal dissection from January 2008 to June 2019 at the Fujian Provincial Hospital or Fujian Provincial Hospital South Branch were analyzed. The following information was extracted from clinical records: general data, preoperative conditions, and pathological data of each lesion after surgery. In total, 23 patients with MEGC or HGIN were evaluated (average age 64 ± 6 years, 17 (73.9%) males). MEGC and HGIN accounted for 4.9 percent of all cases, in which 19 (4.1%) were synchronous multiple cancers and 4 (0.8%) cases were metachronous multiple cancers. Lesions of synchronous and metachronous MEGC groups did not differ in age, sex, smoking history, alcohol consumption, family history of tumors, Helicobacter pylori infection, mucosal background atrophy, or intestinal metaplasia (P > .05). The vertical locations of primary and secondary lesions of MEGC were correlated (R = 0.395, P = .034). The primary and secondary lesions of MEGC shared the same macroscopic subtype (R = 0.590, P = .015), infiltration depth (R = 0.455, P = .014), and pathological subtype (R = 0.736, P < .001). MEGC and HGIN were located in close proximity. Pathologic types tended to be low-grade malignancies. The macroscopic type, histology type, and infiltration depth of the 2 lesions were significantly correlated. When detecting early gastric cancer, we should inspect the stomach and carefully consider the pathological characteristics, to improve the diagnosis of MEGC.

J Dig Dis 2021; 22:637-644. [PMID: 34480521 DOI: 10.1111/1751-2980.13050] [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] [Received: 04/09/2021] [Revised: 08/11/2021] [Accepted: 09/01/2021] [Indexed: 12/11/2022]
Abstract
OBJECTIVE To establish a new and easy-to-use risk-scoring predictive model to help identify high-risk patients with multiple synchronous gastric neoplasms (MSGN), including early gastric cancer (EGC) and gastric dysplasia (GD), before initial endoscopic resection (ER). METHODS We retrospectively enrolled 1361 patients with EGC or GD who had undergone ER from November 2006 to September 2019. The patients were randomly divided into the training (n = 681) and validation cohorts (n = 680). In the training phase a prediction score was constructed to assess the independent predictors of MSGN based on multivariate logistic regression analysis. The performance of the prediction model was evaluated using the receiver operating characteristic (ROC) curve and the Hosmer-Lemeshow test. RESULTS Of the 1361 patients, 122 (9.0%) had MSGN. Three predictors for MSGN were scored and weighted, as follows: elderly male (≥65 y; three points), a family history of gastric cancer (two points) and surface redness (two points). Accordingly, patients were divided into the low (risk score, 0-3 points) or high-risk groups (risk score, 4-7 points). In the validation cohort, the incidence of MSGN in the low-risk and high-risk groups were 6.1% and 32.0%, respectively (P < 0.001). Our predictive risk-scoring model showed good discrimination (the area under the ROC curve [AUROC] 0.719, 95% confidence interval [CI] 0.634-0.794, P < 0.001) and calibration ability (Hosmer-Lemeshow test, χ2 = 6.539, P = 0.587) in the validation group. CONCLUSION This risk-scoring model has a good performance in predicting MSGN before the initial ER.

Risk factor-based optimal endoscopic surveillance intervals after endoscopic submucosal dissection for gastric adenoma. Sci Rep 2021; 11:21408. [PMID: 34725444 PMCID: PMC8560818 DOI: 10.1038/s41598-021-00969-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Accepted: 10/14/2021] [Indexed: 11/17/2022] Open
Abstract
To date, there exists no established endoscopic surveillance interval strategy after endoscopic submucosal dissection (ESD) for gastric adenoma. In this study, we suggest a risk factor-based statistical model for optimal surveillance intervals for gastric adenoma after ESD with curative resection. A cox proportional hazard model was applied to identify risk factors for recurrence after ESD. Patients (n = 698) were categorized into groups based on the identified risk factors. The cumulative density of recurrence over time was computed using a cubic splined baseline hazard function, and the customized surveillance interval was modeled for each risk group. The overall cumulative incidence of recurrence was 7.3% (n = 51). Risk factors associated with recurrence were male (hazard ratio [HR], 2.60, P = 0.030), protruded scar (HR, 3.18, P < 0.001), and age ≥ 59 years (HR, 1.05, P < 0.001). The surveillance interval for each group was developed by using the recurrence limit for the generated risk groups. According to the developed schedule, high-risk patients would have a maximum of seven surveillance visits for 5 years, whereas low-risk patients would have biennial surveillance for cancer screening. We proposed a simple and promising strategy for determining a better endoscopic surveillance interval by parameterizing diverse and group-specific recurrence risk factors into a well-known survival model.

Abstract
Background In Japan, the prevalence of synchronous multiple intramucosal gastric carcinoma is reported to be 5–15%. Here is a case of a synchronous small gastric carcinoma fulfilling the definite indication and curative criteria for endoscopic submucosal dissection with multiple lymph node metastases. Case presentation A Japanese woman in her fifties with a history of endoscopic resection for mucosal poorly differentiated adenocarcinoma was evaluated, with the UICC TNM classification stage being cT1aN0M0 cStageIA. She had undergone total gastrectomy with D1 + lymph node dissection. Histopathological examination revealed 16 individual sporadic lesions in the gastric body, with maximum diameter 3 mm and localization in the lamina propria. Twenty-seven nodes were resected, and metastasis of the carcinoma was revealed in 24 nodes. Conclusions Undifferentiated intramucosal gastric cancer has a relatively high probability of lymph node metastasis; however, synchronous early lesions are often overlooked. Frequent follow-up examinations may increase the detection of multiple gastric cancers.

Abstract
BACKGROUND AND AIM Endoscopic examination of gastric atrophy has been developed to determine the extent of atrophy by identifying the atrophic border of gastric mucosa, but its value in predicting the risk of developing gastric neoplasms is not quantified. Thus, this systematic review and meta-analysis aim to assess the incidence risk of gastric neoplasms on the basis of endoscopic grading of gastric atrophy. METHODS Two authors independently searched the electronic databases (PubMed, Embase, and the Cochrane Library) from inception through December 31, 2019, without language restriction. The effect size on study outcomes is calculated using random-effects model and presented as risk ratio (RR) with 95% confidence interval (CI). Heterogeneity, publication bias, and quality of included studies were also assessed. RESULTS Fourteen retrospective studies are identified to perform systematic review and meta-analysis, 11 were cohort studies, and three were cross-sectional research. The pooled RR for developing gastric neoplasms is 3.89 (95% CI 2.92-5.17) among general patients with severe endoscopic atrophy. For patients who underwent endoscopic resection for early gastric neoplasms, nearly two times increased risk of synchronous or metachronous neoplasms is pooled (RR = 1.96, 95% CI 1.39-2.75). In terms of the type of endoscopic atrophy, patients with open-type endoscopic atrophy have a higher risk of gastric cancer development (RR 8.02; 95% CI 2.39-26.88) than those with close type. [Correction added on 22 December 2020, after first online publication: '(RR = 7.27; 95% CI 1.64-32.33)' has been corrected to '(RR 8.02; 95% CI 2.39-26.88)'] CONCLUSIONS: Grading endoscopic atrophy according to the Kimura-Takemoto classification can assess the risk of gastric neoplasia development. Patients with severe or open-type endoscopic gastric atrophy at baseline should undergo rigorous surveillance to early detect premalignant lesions and cancer.

Gastric cancer screening in low incidence populations: Position statement of AEG, SEED and SEAP. GASTROENTEROLOGIA Y HEPATOLOGIA 2020; 44:67-86.

Abstract
This positioning document, sponsored by the Asociación Española de Gastroenterología, the Sociedad Española de Endoscopia Digestiva and the Sociedad Española de Anatomía Patológica, aims to establish recommendations for the screening of gastric cancer (GC) in low incidence populations, such as the Spanish. To establish the quality of the evidence and the levels of recommendation, we used the methodology based on the GRADE system (Grading of Recommendations Assessment, Development and Evaluation). We obtained a consensus among experts using a Delphi method. The document evaluates screening in the general population, individuals with relatives with GC and subjects with GC precursor lesions (GCPL). The goal of the interventions should be to reduce GC related mortality. We recommend the use of the OLGIM classification and determine the intestinal metaplasia (IM) subtype in the evaluation of GCPL. We do not recommend to establish endoscopic mass screening for GC or Helicobacter pylori. However, the document strongly recommends to treat H.pylori if the infection is detected, and the investigation and treatment in individuals with a family history of GC or with GCPL. Instead, we recommend against the use of serological tests to detect GCPL. Endoscopic screening is suggested only in individuals that meet familial GC criteria. As for individuals with GCPL, endoscopic surveillance is only suggested in extensive IM associated with additional risk factors (incomplete IM and/or a family history of GC), after resection of dysplastic lesions or in patients with dysplasia without visible lesion after a high quality gastroscopy with chromoendoscopy.

Abstract
Detection of early-stage gastric cancer improves the prognosis of patients. Endoscopic submucosal dissection (ESD) is a curative and stomach-preserving treatment for early gastric cancer (EGC) associated with a low risk of lymph node metastasis. However, several studies have reported missed diagnosis of gastric cancer. Therefore, endoscopists are required to learn accurate diagnostic skills to eliminate endoscopic blind spots. A systematic screening protocol to map the entire stomach without blind spots reduces the risk of missed lesions. Knowledge of the features of EGC or dysplasia is essential to identify suspicious lesion. Information of the common sites of occurrence of EGC can also enable a detailed endoscopic examination to improve detection rates. Previous reports investigating the location of gastric cancers resected by ESD or surgery showed that the antrum and lesser curvature of stomach were predominantly affected. Helicobacter pylori-induced atrophic changes advance from the antrum to the corpus along the lesser curvature, predominantly affecting these areas. Gastric cancers in the antrum and the lower corpus are also commonly missed during screening examination. Therefore, a careful examination of the lower third stomach is warranted to avoid missing synchronous and metachronous gastric lesions. Knowledge of the location of EGC enables accurate endoscopic examination and detection of EGC in early stage.

Abstract
The assessment of endoscopic gastric atrophy (EGA) according to the Kimura-Takemoto classification has been reported to correlate well with histological assessment. Although agreement among beginner endoscopists was less than that among experienced endoscopists, it has been shown that agreement level could markedly improve and remained stable after proper training. Several cohort studies have consistently shown that the severity of EGA at baseline is significantly associated with the presence of advanced precancerous gastric lesions and gastric cancer, as well as the development of gastric cancer in future. Patients with moderate-to-severe EGA still have high risk of gastric cancer even after successful Helicobacter pylori eradication and should be candidates for gastric cancer surveillance. The assessment of EGA, therefore, could be used as a preliminary tool to identify individuals at high risk for gastric cancer. In this paper, we review the agreement on mucosal atrophy assessment between the Kimura-Takemoto classification and histology as well as the potential application of this endoscopic classification to identify precancerous gastric lesions and gastric cancer in daily practice.
