Proposal of age definition for early-onset gastric cancer based on the Korean Gastric Cancer Association nationwide survey data: a retrospective observational study. Ann Surg Treat Res 2025; 108:245-255. [PMID: 40226172 PMCID: PMC11982448 DOI: 10.4174/astr.2025.108.4.245] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2024] [Revised: 12/30/2024] [Accepted: 01/07/2025] [Indexed: 04/15/2025] Open
Abstract
Purpose This study aimed to define an optimal age cutoff for early-onset gastric cancer (EOGC) and compare its characteristics with those of late-onset gastric cancer (LOGC) using nationwide survey data. Methods Using data from a nationwide survey, this comprehensive population-based study analyzed data spanning 3 years (2009, 2014, and 2019). The joinpoint analysis and interrupted time series (ITS) methodology were employed to identify age cutoffs for EOGC based on the sex ratio and tumor histology. Clinicopathologic characteristics and surgical outcomes were compared between the EOGC and LOGC groups. Results The age cutoff for defining EOGC was suggested to be 50 years, supported by joinpoint and ITS analyses. Early gastric cancer was predominantly present in the EOGC and LOGC groups. Patients with EOGC comprised 20.3% of the total study cohort and demonstrated a more advanced disease stage compared to patients with LOGC. However, patients with EOGC underwent more minimally invasive surgeries, experienced shorter hospital stays, and had lower postoperative morbidity and mortality rates. Conclusion This study proposes an age of ≤50 years as a criterion for defining EOGC and highlights its features compared to LOGC. Further research using this criterion should guide tailored treatment strategies and improve outcomes for young patients with gastric cancer.

Machine Learning Prediction of Early Recurrence in Gastric Cancer: A Nationwide Real-World Study. Ann Surg Oncol 2025; 32:2637-2650. [PMID: 39738899 DOI: 10.1245/s10434-024-16701-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2024] [Accepted: 11/28/2024] [Indexed: 01/02/2025]
Abstract
BACKGROUND Patients with gastric cancer (GC) who experience early recurrence (ER) within 2 years postoperatively have poor prognoses. This study aimed to analyze and predict ER after curative surgery for patients with GC using machine learning (ML) methods. PATIENTS AND METHODS This multicenter population-based cohort study included data from ten large tertiary regional medical centers in China. The clinical, pathological, and laboratory parameters were retrospectively collected from the records of 11,615 patients. The patients were randomly divided into training (70%) and test (30%) cohorts. A total of ten ML models were developed and validated to predict the ER. Model performance was evaluated using area under the receiver operating characteristic curve (AUC), calibration plots, and Brier score (BS). SHapley Additive exPlanations (SHAP) was used to rank the input features and interpret predictions. RESULTS ER was reported in 1794 patients (15%) during follow-up. The stacking ensemble model achieved AUCs of 1.0 and 0.8 in the training and testing cohorts, respectively, with a BS of 0.113. SHAP dependency plots revealed that tumor staging, elevated tumor marker levels, lymphovascular invasion, perineural invasion, and tumor size > 5 cm were associated with higher ER risk. The impact of age and the number of lymph nodes harvested on ER risk exhibited a "U-shaped distribution." Additionally, an online prediction tool based on the best model was developed to facilitate clinical applications. CONCLUSIONS We developed a robust clinical model for predicting the risk of ER after surgery for GC, which may aid in individualized clinical decision-making.

Machine learning models for prediction of lymph node metastasis in patients with gastric cancer: a Chinese single-centre study with external validation in an Asian American population. BMJ Open 2025; 15:e098476. [PMID: 40132850 PMCID: PMC11938237 DOI: 10.1136/bmjopen-2024-098476] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2024] [Accepted: 02/28/2025] [Indexed: 03/27/2025] Open
Abstract
OBJECTIVE To develop and validate machine learning (ML)-based models to predict lymph node metastasis (LNM) in patients with gastric cancer (GC). DESIGN Retrospective cohort study. SETTING Second Affiliated Hospital of Soochow University. PARTICIPANTS A total of 500 inpatients from the Second Affiliated Hospital of Soochow University, collected retrospectively between 1 April 2018 and 31 March 2023, were used as the training set, while 824 Asian patients from the Surveillance, Epidemiology and End Results database comprised the external validation set. MAIN OUTCOME MEASURES Prediction models were developed using multiple ML algorithms, including logistic regression, support vector machine, k-nearest neighbours, naive Bayes, decision tree (DT), gradient boosting DT, random forest and artificial neural network (ANN). The predictive value of these models was validated and evaluated through receiver operating characteristic curves, precision-recall (PR) curves, calibration curves, decision curve analysis and accuracy metrics. RESULTS Among the ML algorithms, the ANN outperformed others, achieving the highest accuracy (0.722; 95% CI: 0.692 to 0.751), precision (0.732; 95% CI: 0.694 to 0.776), F1 score (0.733; 95% CI: 0.695 to 0.773), specificity (0.728; 95% CI: 0.684 to 0.770) and area under the PR curve (0.781; 95% CI: 0.740 to 0.821) in the external validation results. Moreover, it demonstrated superior calibration and clinical utility. Shapley Additive Explanations analysis identified the depth of invasion, tumour size and Lauren classification as the most influential predictors of LNM in patients with GC. Furthermore, a user-friendly web application was developed to provide individual prediction results. CONCLUSIONS This study introduces an accurate, reliable and clinically applicable approach for predicting the risk of LNM in patients with GC. The model demonstrates its potential to enhance the personalised management of GC in diverse populations, supported by external validation and an accessible web application for practical use.

Bone Metastasis Mediates Poor Prognosis in Early-Onset Gastric Cancer: Insights Into Immune Suppression, Coagulopathy, and Inflammation. Cancer Med 2025; 14:e70737. [PMID: 40040540 PMCID: PMC11880774 DOI: 10.1002/cam4.70737] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2024] [Revised: 01/17/2025] [Accepted: 02/21/2025] [Indexed: 03/06/2025] Open
Abstract
BACKGROUND The increasing incidence of gastric cancer (GC) in younger populations, coupled with population aging, has highlighted distinct age-related subtypes with unique clinical characteristics and outcomes. Although younger patients tend to have more aggressive tumors, the prognostic factors for early-onset gastric cancer (EOGC) remain underexplored. This study is dedicated to providing a comprehensive and in-depth analysis of prognostic factors in EOGC, aiming to refine personalized treatment strategies under the precision medicine paradigm. METHODS This retrospective study encompassed 413 local cohort EOGC patients and 8447 Surveillance, Epidemiology, and End Results database patients diagnosed with GC. Survival outcomes were assessed using Kaplan-Meier survival curves, and differences between groups were evaluated with the log-rank test. Prognostic factors were identified through logistic regression and Cox proportional hazards models. Mediation analysis was conducted to assess the indirect effects of clinical factors on EOGC and prognosis. Biomarker comparisons between bone metastasis early-onset gastric cancer and non-bone metastasis early-onset gastric cancer groups were evaluated using the Wilcoxon test for significant differences. RESULTS The overall survival and cancer-specific survival rates in the EOGC group were significantly lower than those in the non-early-onset gastric cancer group (p < 0.05). However, EOGC itself was not an independent risk factor for poor prognosis. Mediation analysis revealed that the adverse impact of EOGC on prognosis was predominantly mediated by metastasis, with bone metastasis identified as the most significant factor. Furthermore, bone metastasis emerged as an independent predictor of poor prognosis in EOGC patients, potentially linked to elevated coagulation markers, increased inflammation-related cytokines, and an imbalance in peripheral blood immune cell ratios. CONCLUSIONS Bone metastasis significantly contributes to the poor prognosis of EOGC. EOGC patients with bone metastasis demonstrate immune suppression, inflammation activation, and coagulopathy, highlighting the need for tailored management and prognostic strategies.

Short- and long-term outcomes of robotic- versus laparoscopic-assisted early-onset gastric cancer: a propensity score-matched retrospective cohort study. BMC Cancer 2025; 25:361. [PMID: 40016662 PMCID: PMC11866809 DOI: 10.1186/s12885-025-13767-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2025] [Accepted: 02/18/2025] [Indexed: 03/01/2025] Open
Abstract
BACKGROUND Early-onset gastric cancer (EOGC) is a distinct subtype of gastric cancer with increasing incidence, characterized by unique clinical and pathological features. This propensity score-matched retrospective cohort study aims to compare the perioperative safety and outcomes of EOGC patients who underwent laparoscopic versus robotic radical gastrectomy, providing a scientific basis for surgical treatment of EOGC. MATERIALS AND METHODS We included 252 patients diagnosed with EOGC at or before the age of 45, who underwent robotic or laparoscopic radical gastrectomy between January 2015 and April 2021. After propensity score matching, 47 patients in the robotic surgery group and 94 in the laparoscopic surgery group were compared. The study evaluated intraoperative and postoperative outcomes, pathological results, and long-term survival. RESULTS The robotic surgery group showed less intraoperative bleeding (50 ml vs. 100 ml, p = 0.042) and shorter postoperative hospital stays (6 days vs. 7 days, p = 0.008) compared to the laparoscopic group. The number of positive lymph nodes was higher in the robotic group (median 2 vs. 1, p = 0.016), but the number of lymph nodes harvested did not significantly differ. No significant differences were found in overall survival (3-year OS: 65.9% vs. 62.5%, p = 0.596) and disease-free survival (3-year DFS: 61.4% vs. 61.7%, p = 0.765) between the two groups. CONCLUSIONS Robotic resection for EOGC is non-inferior to laparoscopic surgery in terms of perioperative outcomes and long-term prognosis. This study suggests that robotic surgery may be a viable option for the treatment of EOGC.

Abstract
Gastric cancer (GC) is one of the most common cancers in the world. It is a multi-factorial disease influenced by both genetic and environmental factors such as diet, obesity, radiation exposure, and infectious agents. Viral infections usually lead to chronic inflammation, which can initiate the development of cancers. To date, only a few studies have been published about Epstein-Barr virus (EBV) and human papillomavirus (HPV) infections in the context of the development of GC. In particular, research on the development of cancer among people under 45 years of age, including the impacts of EBV and HPV, is rare, and clear results have not been obtained. The aim of this study was to analyze the frequency of occurrence of EBV and HPV in GC, particularly in early-onset gastric cancer (EOGC). Tissue material from 135 patients with GC, including 84 men and 51 women, was examined. RT-PCR was performed to detect EBV, and PCR was performed to detect HPV. There were no significant impacts of EBV and HPV infections on any subtype of GC. There was also no statistically significant dependence of gender and location of the tumor on any subtype of GC. Further research on the impacts of infectious agents such as EBV and HPV on GC should be conducted using larger populations.

Abstract
PURPOSE Fibroblast growth factor receptor 2 isoform IIIb (FGFR2b) protein overexpression is an emerging biomarker in gastric cancer and gastroesophageal junction cancer (GC). We assessed FGFR2b protein overexpression prevalence in nearly 3,800 tumor samples as part of the prescreening process for a global phase III study in patients with newly diagnosed advanced or metastatic GC. METHODS As of June 28, 2024, 3,782 tumor samples from prescreened patients from 37 countries for the phase III FORTITUDE-101 trial (ClinicalTrials.gov identifier: NCT05052801) were centrally tested for FGFR2b protein overexpression by immunohistochemistry (IHC) and had evaluable results. FGFR2b positivity was defined as both any % tumor cells (TC) and ≥10% TC exhibiting moderate-to-strong (2+/3+) membranous FGFR2b staining. Prevalence was analyzed across patient and sample characteristics. RESULTS FGFR2b protein overexpression at any % and ≥10%, 2+/3+ TC positivity was 37.8% (1,428/3,782 [95% CI, 36.2 to 39.3]) and 16.2% (612/3,782 [95% CI, 15 to 17.4]), respectively. Of any %, 2+/3+ TC-positive tumors, 42.9% (612/1,428 [95% CI, 40.3 to 45.4]) were FGFR2b ≥10%, 2+/3+ TC positive. FGFR2b prevalence was not notably different within multiple patient and sample characteristics examined (age, sex, collection method [biopsy v resection], collection site, location of primary tumor, and geographic region). CONCLUSION As of the data cutoff date, we report the largest prevalence assessment of FGFR2b protein overexpression in GC with more than one third (37.8%) of patients with GC exhibiting FGFR2b protein overexpression (any % TC, 2+/3+) by a validated IHC assay. Approximately 16% of patients had FGFR2b protein overexpression in ≥10% of TC. FGFR2b prevalence was similar across geographic regions and within defined patient and sample variables regardless of the level of expression.

Front Oncol 2024; 14:1476340. [PMID: 39735603 PMCID: PMC11672336 DOI: 10.3389/fonc.2024.1476340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2024] [Accepted: 11/12/2024] [Indexed: 12/31/2024] Open
Abstract
Purpose This study aimed to develop and validate a model for accurately assessing the risk of distant metastases in patients with gastric cancer (GC). Methods A total of 301 patients (training cohort, n = 210; testing cohort, n = 91) with GC were retrospectively collected. Relevant clinical predictors were determined through the application of univariate and multivariate logistic regression analyses. Then the clinical model was established. Venous phase computed tomography (VPCT) images were utilized to extract radiomic features, and relevant features were selected using univariate analysis, Spearman correlation coefficient, and the least absolute shrinkage and selection operator (Lasso) regression. Subsequently, radiomics scores were calculated based on the selected features. Radiomics models were constructed using five machine learning algorithms according to the screened features. Furthermore, separate joint models incorporating radiomic features and clinically independent predictors were established using traditional logistic regression algorithms and machine learning algorithms, respectively. All models were comprehensively assessed through discrimination, calibration, reclassification, and clinical benefit analysis. Results The multivariate logistic regression analysis revealed that age, histological grade, and N stage were independent predictors of distant metastases. The radiomics score was derived from 15 selected features out of a total of 944 radiomic features. The predictive performance of the joint model 1 [AUC (95% CI) 0.880 (0.811-0.949)] constructed using logistic regression is superior to that of the joint model 2 [AUC (95% CI) 0.834 (0.736-0.931)] constructed using SVM algorithm. The joint model 1 [AUC(95% CI) 0.880(0.811-0.949)], demonstrated superior performance compared to the clinical model [AUC(95% CI) 0.781(0.689-0.873)] and radiomics model [AUC(95% CI) 0.740(0.626-0.855), using LR algorithm]. The NRI and IDI values for the joint model 1 and clinical model were 0.115 (95% CI 0.014 -0.216) and 0.132 (95% CI 0.093-0.171), respectively; whereas for the joint model 1 and LR model, they were found to be 0.130 (95% CI 0.018-0.243) and 0.116 (95% CI 0.072-0.160), respectively. Decision curve analysis indicated that the joint model 1 exhibited a higher clinical net benefit than other models. Conclusions The nomogram of the joint model, integrating radiomic features and clinically independent predictors, exhibits robust predictive capability for early identification of high-risk patients with a propensity for distant metastases of GC.

Trends, clinicopathological features, surgical treatment patterns and prognoses of early-onset versus late-onset gastric cancer: A retrospective cohort study. J Adv Res 2024:S2090-1232(24)00548-4. [PMID: 39586373 DOI: 10.1016/j.jare.2024.11.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2024] [Revised: 11/19/2024] [Accepted: 11/22/2024] [Indexed: 11/27/2024] Open
Abstract
INTRODUCTION This study investigates the differences between early-onset gastric carcinoma (EOGC) and late-onset gastric carcinoma (LOGC) by examining trends, demographics, clinical and molecular features, treatments, and outcomes at a leading cancer center in China. OBJECTIVES To delineate the distinctions between EOGC and LOGC in terms of patient characteristics, disease progression, and treatment outcomes, and to suggest appropriate screening strategies. METHODS We analyzed 18,877 gastric carcinoma cases treated at Fudan University Shanghai Cancer Center (FUSCC) from 2000 to 2022. Descriptive statistics were performed using IBM SPSS. Survival rates were assessed via the Kaplan-Meier method and log-rank test, while COX regression analysis identified factors affecting disease-free survival (DFS) and overall survival (OS). RESULTS The average age of gastric cancer diagnosis has increased slightly since 2000, with a steady rise in both EOGC and LOGC cases, though EOGC's proportion has slightly decreased. EOGC had a higher proportion of female patients and was more common in the gastric body and antrum pylorus. EOGC cases showed lower levels of cancer biomarkers, HER2 expression, vascular and lymphatic invasion, and lower differentiation and invasion depth. They also exhibited more advanced N and TNM staging, Borrmann IV type, and low adhesive carcinoma. EOGC underwent more extensive D2 lymphadenectomy and neoadjuvant chemotherapy. There were no significant differences in Claudin18.2 and MMR protein status between EOGC and LOGC. EOGC had higher rates of ovarian and peritoneal metastases, with a better early prognosis but faster late-stage progression. CONCLUSION EOGC and LOGC cases have increased over the past two decades. EOGC presents unique clinical and pathological features, requiring thorough surgical treatment and has a better early prognosis but more rapid late-stage progression. Enhanced screening for younger adults is recommended to address the rising EOGC trend.

Abstract
Gastric cancer (GC) is the fifth most frequently diagnosed cancer and the fifth most common cause of cancer death in the world. Regarding the age at which the diagnosis was made, GC is divided into early-onset gastric cancer (EOGC-up to 45 years of age) and conventional GC (older than 45). EOGC constitutes approximately 10% of all GCs. Numerous reports indicate that EOGC is more aggressive than conventional GC and is often discovered at an advanced tumor stage, which has an impact on the five-year survival rate. The median survival rate for advanced-stage GC is very poor, amounting to less than 12 months. Risk factors for GC include family history, alcohol consumption, smoking, Helicobacter pylori, and Epstein-Barr virus infection. It has been shown that a proper diet and lifestyle can play a preventive role in GC. However, research indicates that risk factors for conventional GC are less correlated with EOGC. In addition, the unclear etiology of EOGC and the late diagnosis of this disease limit the possibilities of effective treatment. Genetic factors are considered a likely cause of EOGC, as young patients are less exposed to environmental carcinogens. Research characterizing GC in young patients is scarce. This comprehensive study presents all aspects: epidemiology, risk factors, new treatment strategies, and future directions.

Gastric Cancer 2024; 27:684-700. [PMID: 38570392 PMCID: PMC11193827 DOI: 10.1007/s10120-024-01494-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Accepted: 03/13/2024] [Indexed: 04/05/2024]
Abstract
BACKGROUND While gastric cancer is generally declining globally, the temporal trend of young-onset (< 40 years) gastric cancer remains uncertain. We performed this analysis to determine the temporal trends of young-onset gastric cancer compared to late-onset cancer (≥ 40 years). METHODS We extracted cross-sectional data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. The burden of gastric cancer from 1990 to 2019 was assessed through indicators including incidence and mortality rates, which were classified at global, national, and regional levels, and according to socio-demographic indexes (SDI) and age or sex groups. Joinpoint regression analysis was used to identify specific years with significant changes. The correlation between AAPC with countries' average SDI was tested by Pearson's Test. RESULTS The global incidence rate of young-onset gastric cancer decreased from 2.20 (per 100,000) in 1990 to 1.65 in 2019 (AAPC: - 0.95; 95% confidence interval [CI] - 1.25 to - 0.65; P < 0.001). Late-onset cancer incidence also decreased from 59.53 (per 100,000) in 1990 to 41.26 in 2019 (AAPC: - 1.23; 95% CI - 1.39 to - 1.06, P < 0.001). Despite an overall decreasing trend, the incidence rate of young-onset cancer demonstrated a significant increase from 2015 to 2019 (annual percentage change [APC]: 1.39; 95% CI 0.06 to 2.74; P = 0.041), whereas no upward trend was observed in late-onset cancer. Mortality rates of young- and late-onset cancer both exhibited a significant decline during this period (AAPC: - 1.82; 95% CI - 2.15 to - 1.56; P < 0.001 and AAPC: - 1.69, 95% CI - 1.79 to - 1.59; P < 0.001). The male-to-female rate ratio for incidence and mortality in both age groups have been increasing since 1990. While countries with high SDI have had a greater decline in the incidence of late-onset gastric cancer (slope of AAPC change: - 0.20, P = 0.004), it was not observed in young-onset cancer (slope of AAPC change: - 0.11, P = 0.13). CONCLUSIONS The global incidence and mortality rates of both young- and late-onset gastric cancer have decreased since 1990. However, the incidence rate of young-onset cancer has demonstrated a small but significant upward trend since 2015. There was disparity in the decline in young-onset gastric cancer among male and high SDI countries. These findings could help to inform future strategies in preventing gastric cancer in younger individuals.

Abstract
Introduction Gastric cancer is a significant major global health concern, particularly prevalent in Asia. In recent years, a large number of new cases have been diagnosed worldwide, leading to a substantial number of deaths. The disease tends to present more aggressively in these cases, leading to debates about the prognosis and survival outcomes. Nonetheless, research has shown that survival rates improve significantly when the tumor is completely surgically resected. Materials and methods This retrospective study included patients between 16 and 45 years old, diagnosed with gastric cancer, with the support of the pathology department, who underwent surgery in the upper GI service, in the period from January 2006 to December 2012. Data collected encompassed variables such as gender, age, tumor size, type of surgery, overall survival, disease-free period, type and histological degree of the tumor, clinical stage of the cancer, and R0 resection (curative resection). All patients with a confirmed diagnosis of gastric cancer were included and treated with surgery and D1 limited dissection or extended D2 dissection. Patients who have received chemotherapy prior to surgical treatment and those who have been surgically treated outside the XXI Century National Medical Center were excluded. Results A total of 104 patients were included; the predominant histological type was diffuse adenocarcinoma accounting for 79.8% and 81.7% of the cases were histological grade 3. The most common clinical stage was IIIA in 41.3% of the cases. In 53.8% of the cases, we obtained an R0 resection. D2 lymphadenectomy was performed in 53.8% of the cases, with an overall survival rate of 82.69%. Significant prognostic factors for survival included T4 depth with an increase in risk for mortality (OR: 25.93; 95% CI: 6.41-53.54; p=0.001), lymph node status (OR: 14.76; 95% CI: 4.6-46.83; p<0.001), and size greater than 5 cm (OR: 1.8; 95% CI: 0.61-6.35; p<0.001). Conclusions Gastric cancer is more common in adults aged above 60 years old, but the incidence in young adults under 45 years old has been increasing. Although young gastric cancer patients present with more aggressive tumor behavior, these patients can have similar or even better overall survival compared to older patients, being 35% in some cases, especially in the resectable setting. Further research is still needed to fully characterize the unique biology and optimal management of gastric cancer in young adults.

Abstract
Gastric cancer poses a significant global health challenge, with high incidence and mortality rates each year. Despite advancements in screening and treatment, late detection remains a critical issue. Efforts to address this include raising public awareness and implementing targeted screening programs for high-risk populations. The increasing incidence of gastric cancer among younger individuals underscores the need for lifestyle adjustments and targeted interventions to mitigate risks and improve outcomes. Understanding the various factors contributing to gastric cancer risk is essential for effective prevention strategies, including Helicobacter pylori eradication, lifestyle modifications, and regular screening for high-risk groups. A comprehensive approach addressing both individual behaviors and broader societal factors is crucial in the fight against gastric cancer. This review provides an in-depth examination of gastric cancer epidemiology, risk factors, preventive measures, and screening initiatives, with a particular focus on the rising incidence among younger demographics. Emphasizing the importance of early detection and intervention, the review highlights the need for proactive screening to improve patient outcomes and reduce mortality rates. By addressing these aspects comprehensively, this paper aims to enhance the understanding of gastric cancer dynamics, particularly its incidence among younger individuals, and to inform future strategies for prevention and control.

Abstract
INTRODUCTION The characteristics of gastric carcinoma in young individuals differ from that in older individuals. We conducted a systematic review and meta-analysis to explore the clinicopathological features and risk factors associated with young-onset (younger than 50 years) gastric carcinoma. METHODS We searched for studies published between January 1, 1990, and September 1, 2023, on patients with young-onset gastric carcinoma in PubMed, EMBASE, Web of Science, and MEDLINE to explore clinicopathological characteristics among this specific patient group. Extracted information included the proportion of patients with symptoms or family history of gastric cancer, tumor location, and histological features such as Lauren or World Health Organization histological classification and degree of differentiation. Additional analyses were conducted on risk factors such as positive family history, Helicobacter pylori infection, or high-risk nutritional or behavioral factors. The estimates were derived using random or fixed-effect models and included subgroup analyses based on different sex and age groups. This study was registered in PROSPERO (CRD42023466131). RESULTS We identified 5,696 records, 1,292 were included in the quality assessment stage. Finally, 84 studies from 18 countries or regions including 89,447 patients with young-onset gastric carcinoma were included. Young-onset gastric carcinoma has slight female predominance (53.7%, 95% confidence interval [CI]: 51.6-55.7%), with most having symptoms (87.0%, 95% CI: 82.4%-91.7%). Family history was reported in 12.1% (95% CI: 9.5%-14.7%). H. pylori infection was detected in 60.0% of cases (95% CI: 47.1%-72.8%). Most of these carcinomas were in the non-cardia region (89.6%, 95% CI: 82.4%-96.8%), exhibiting Lauren diffuse-type histology (71.1%, 95% CI: 66.8%-75.3%) and poor/undifferentiated features (81.9%, 95% CI%: 79.7-84.2%). A positive family history of gastric cancer was the most important risk factor associated with the development of gastric carcinoma in young individuals (pooled odds ratios 4.0, 95% CI: 2.8-5.2), followed by H. pylori infection (odds ratio 2.3; 95% CI: 1.4-3.2) and dietary and other lifestyle risk factors. DISCUSSION Young-onset gastric carcinoma exhibits specific clinicopathological characteristics, with positive family history being the most important risk factor. Most of the patients were symptomatic at diagnosis. These findings could help to inform future strategies for the early detection of gastric carcinoma among young individuals.

Abstract
BACKGROUND The effect of radiotherapy waiting time after last induction chemotherapy (IC-RT) on prognosis of patients with locally advanced nasopharyngeal carcinoma (LANPC) needs further discussion. METHODS Three hundred and six patients with LANPC diagnosed pathologically by induction chemotherapy (IC) and radiotherapy (RT) from 2013 to 2018 were selected for this study. RESULTS The IC-RT was a risk factor for the post-treatment progression of LANPC (OR = 1.017 95%CI: 1.003-1.031), For patients with LANPC, the IC-RT > 40 days significantly reduced 5-year PFS (70% vs. 55%; p = 0.0012), 5-year OS (84% vs. 73%; p = 0.028), 5-year DMFS (80% vs. 66%; p = 0.003), 5-year LRFS (77% vs. 67%; p = 0.012). Indicating that patients with stage IVa who IC-RT > 40 days were found to be a significant predictor of aggravated PFS (HR = 2.69; 95%CI: 1.57-4.6), OS (HR = 2.55; 95%CI: 1.29-5.03), DMFS (HR = 3.07; 95%CI: 1.64-5.76) and LRFS (HR = 2.26; 95%CI: 1.21-4.21). CONCLUSION The prognosis of patients will be adversely affected if the IC-RT exceeds 40 days, especially for stage IVa patients.

Abstract
BACKGROUNDThe tumor immune microenvironment can provide prognostic and therapeutic information. We aimed to develop noninvasive imaging biomarkers from computed tomography (CT) for comprehensive evaluation of immune context and investigate their associations with prognosis and immunotherapy response in gastric cancer (GC).METHODSThis study involved 2,600 patients with GC from 9 independent cohorts. We developed and validated 2 CT imaging biomarkers (lymphoid radiomics score [LRS] and myeloid radiomics score [MRS]) for evaluating the IHC-derived lymphoid and myeloid immune context respectively, and integrated them into a combined imaging biomarker [LRS/MRS: low(-) or high(+)] with 4 radiomics immune subtypes: 1 (-/-), 2 (+/-), 3 (-/+), and 4 (+/+). We further evaluated the imaging biomarkers' predictive values on prognosis and immunotherapy response.RESULTSThe developed imaging biomarkers (LRS and MRS) had a high accuracy in predicting lymphoid (AUC range: 0.765-0.773) and myeloid (AUC range: 0.736-0.750) immune context. Further, similar to the IHC-derived immune context, 2 imaging biomarkers (HR range: 0.240-0.761 for LRS; 1.301-4.012 for MRS) and the combined biomarker were independent predictors for disease-free and overall survival in the training and all validation cohorts (all P < 0.05). Additionally, patients with high LRS or low MRS may benefit more from immunotherapy (P < 0.001). Further, a highly heterogeneous outcome on objective response rate was observed in 4 imaging subtypes: 1 (-/-) with 27.3%, 2 (+/-) with 53.3%, 3 (-/+) with 10.2%, and 4 (+/+) with 30.0% (P < 0.0001).CONCLUSIONThe noninvasive imaging biomarkers could accurately evaluate the immune context and provide information regarding prognosis and immunotherapy for GC.

Abstract
Objective. Early-onset gastric cancer (EOGC) constitutes a serious medical and social problem. Early-onset gastric cancer accounts for approximately 6% of all malignant epithelial neoplasms.Material and Methods. We reviewed retrospective and prospective randomized trials using Medline and Elibrary databases.Results. The applied significance of the molecular genetic classifications consist in the formation of groups for evaluating prognosis of the disease using multifactorial analysis. This classification indicates that EOGC diagnosed at a locally advanced stage and primary dissemination is most often caused by GS (TCGA) and MSS/EMT(ACRG) subtypes and is characterized by mutations in CDH1, RhoA, CLDN18-ARHGAP genes. These changes are accompanied by the prevalence of diffuse histological type of gastric cancer according to the Lauren classification and ulcerated or infiltrative type according to the Borrmann classification (type III and IV) with the presence of high-grade adenocarcinoma with a signet ring cell component.Conclusion. Considering the aggressiveness of gastric cancer in young patients, who more frequently present with locally advanced and metastatic disease at the time of diagnosis, there is a need for increased cancer alertness among physicians of other specialties, early endoscopic controls to detect cancer at early stages and benefit from both surgical and multimodal treatment.

Abstract
Background We aim to present incidence rates and geographical distribution of most common early-onset gastrointestinal cancers (EOGICs), including early-onset esophageal cancer (EOEC), gastric cancer (EOGC) and colorectal cancer (EOCRC) in Iran, 2014-2018. Methods Data on new cases of EOEC, EOGC and EOCRC were obtained from publicly available annual reports of the Iranian National Population-based Cancer Registry (INPCR). Incidence rates were calculated using the population data available from the Statistical center of Iran. We considered the World standard population for calculation of age-standardized incidence rates (ASR). We also calculated 95% confidence intervals (CIs) for ASR. All rates are presented per 100000 person-years. Results Overall, 19,679 new cases of EOGIC were registered by the INPCR between 2014 and 2018. The ASRs (95% CI) of EOEC, EOGC and EOCRC were 0.49 (95% CI: 0.47-0.51), 1.67 (1.63-1.71), and 3.07 (3.01-3.13) per 100,000 person-years, respectively. Our findings indicate decreasing and constant trends in the ASR of EOEC and EOGC during the study period, 2014-2018. There was an increasing trend in the ASR of EOCRC. We also found geographical disparities in the incidence rates of EOGICs across provinces of Iran, suggesting the highest ASRs of EOEC in Golestan (1.3), EOGC in Ilam (2.99) and EOCRC in Ilam (4.49). Conclusion Our findings suggested that the incidence rate of EOCRC is consistently increasing. We also found variations in the incidence of EOGICs among different provinces. Further investigations are recommended to clarify the time trends and risk factors of EOGICs in Iran.

Abstract
BACKGROUND Gastroesophageal adenocarcinoma in young adults (GCYA) counts for 10-15% of diagnoses. Previous studies have mainly focused on surgical outcomes in patients with resectable tumors; however, systemic therapy for advanced GCYA remains under-evaluated. This study aims to assess the efficacy-related outcomes and safety of first-line chemotherapy (CT) in younger versus older patients with advanced gastroesophageal adenocarcinoma. METHODS Patients with advanced gastroesophageal adenocarcinoma from the AGAMENON-SEOM registry treated with first-line polychemotherapy between January 2008 and October 2022 were included. We compared clinicopathological features, therapies received, efficacy-related outcomes, and toxicity between individuals aged < and ≥ 45 years. RESULTS Out of 3386 patients, 263 (7.8%) were < 45 years. Young patients exhibited a higher proportion of females affected, lower ECOG-PS ≥ 2, fewer comorbidities, and more aggressive disease-related features, such as higher proportion of diffuse subtype, signet-ring cells, plastic linitis, grade 3, peritoneal metastases and metastatic disease at diagnosis. They received more triple-agent combinations and underwent more surgeries in metastatic setting. No significant differences were observed between groups in overall response rate (53.1% vs. 52.3% in < and ≥ 45 years, respectively, p = 0.579), progression-free survival (6.1 vs. 6.83 months, p = 0.158) and overall survival (11.07 vs. 10.81 months, p = 0.82), even after adjusting for potential confounding factors. Grade 3-4 adverse events were comparable in both groups, although toxicity leading to treatment discontinuation was more frequent in older patients. CONCLUSIONS In the AGAMENON-SEOM registry, younger patients with GCYA exhibited more aggressive clinicopathological features, and despite receiving more aggressive treatments, similar efficacy outcomes and toxicity profiles were achieved compared to their older counterparts. In the AGAMENON-SEOM registry, GEAC in < 45 years showed more aggressive clinicopathological features and, although treated with more intense first-line CT regimens, similar efficacy outcomes and toxicity were achieved compared to older patients.

Abstract
OBJECTIVE To investigate the effect of Src homology 2 domain-containing tyrosine phosphatase-2 (SHP2) in tumor-associated macrophages (TAMs), which is mediated by macrophage colony-stimulating factor (M-CSF) secreted by gastric cancer cells, on the development of gastric cancer and its molecular mechanism. METHODS The progression of gastric cancer was detected by nude mouse tumor-bearing experiments. Colony formation assay and cell counting kit-8 (CCK8) assay were used to detect the proliferation capacity of gastric cancer cells. The migration capacity of gastric cancer cells was examined by wound healing assay. Transwell migration and invasion assays were performed on gastric cancer cells. Detection of relevant protein expression using western blotting. RESULTS Overexpression of SHP2 could promote the progression of gastric cancer in nude mice. The results of colony formation assay and CCK8 assay showed that overexpression of SHP2 could enhance the proliferation of gastric cancer cells. It was found by wound healing assay and Transwell assay that overexpression of SHP2 could facilitate the migration and invasion of gastric cancer cells. The results of Western blotting revealed that overexpression of SHP2 could increase the expressions of p-STAT3, s-PD-1, p-Src, p-Lyn, p-PI3K, p-AKT, Arginase-1, MMP1 and MMP3 but decrease the expressions of TBK1 and SOCS1 in TAMs, and also increase the expressions of CD9, TSG101 and s-PD-1 in exosomes. CONCLUSION M-CSF secreted by gastric cancer cells can promote the proliferation, invasion and migration of gastric cancer cells by increasing the expression of SHP2 in TAMs.

Abstract
BACKGROUND Mucinous gastric carcinoma (MGC) is a distinct histologic subtype of gastric cancer (GC) that is often diagnosed at an advanced stage. The clinicopathological characteristics and prognosis of MGC, when compared to adenocarcinoma and signet-ring cell carcinoma (SRCC), are currently subjects of debate and require further investigation. METHODS In this study, we conducted an investigation on 4,417 patients who were hospitalized with GC at Zhejiang Cancer Hospital between April 2008 and December 2019. The objective was to compare the prognosis and clinicopathological characteristics of MGC with other types of GC. RESULTS In comparison to adenocarcinoma, MGC patients exhibited more advanced tumor infiltration (p < 0.001), lower tumor differentiation (p < 0.001), and higher rates of preoperative tumor marker positivity (except for AFP and CA125) (all p < 0.05). However, after propensity score matching (PSM) to eliminate confounding factors, MGC patients surprisingly exhibited a better prognosis than adenocarcinoma patients (p = 0.008), and the results in multifactorial COX regression were similar (HR = 0.792, 95% CI 0.629-0.997, p = 0.047). Among patients with MGC, age, pN stage, as well as preoperative levels of CA125 and CA724 (all p < 0.05), emerged as independent prognostic markers. While overall survival did not significantly differ between MGC and SRCC (p = 0.196), significant survival disparities emerged in advanced-stage patients (p = 0.009), with MGC showing better survival rates. Furthermore, a nomogram was developed to predict 1-, 3-, and 5-year survival in gastric cancer patients based on various factors, achieving a C-index of 0.772 (95% CI: 0.745-0.799). CONCLUSIONS While the poorer prognosis associated with MGC may be linked to its advanced stage and lower degree of differentiation, its biological behavior could contribute to improved survival.

Abstract
Gastric cancer (GC), a prevalent disease which globally affects both men and women, was predicted by the International Agency for Research on Cancer in 2020 to have an age-standardized incidence rate (ASIR) in Saudi Arabia of 2.7 per 100,000 individuals for all ages and sexes (ranked 15th), and an age-standardized mortality rate of 2.1 per 100,000 individuals (ranked 12th). The present retrospective study aimed to investigate the prevalence of GC across all administrative regions in Saudi Arabia. Specifically, the present study sought to examine the incidence of diagnosed cases, age-specific incidence rates, crude incidence rates (CIRs) and ASIRs adjusted for age, year and region. To meet this aim, this retrospective descriptive epidemiological analysis was conducted on all cases of GC recorded in the Saudi Cancer Registry (SCR) between January 2004 and December 2017. The collected data were subjected to a range of statistical analyses (using SPSS version 20.0), including descriptive analyses, independent sample t-tests, the Kruskal-Wallis test and sex ratio analysis. In the SCR, a total of 4,066 cases of GC were recorded between 2004 and 2017. The regions with the highest overall ASIRs of GC for both men and women were found to be Riyadh, Najran and the Eastern Region, with rates ranging from 2.2-4.0 per 100,000 individuals. Conversely, Jazan had the lowest ASIRs, with rates of 1.5 and 0.5 per 100,000 individuals for men and women, respectively. The overall ASIRs of GC were found to be significantly higher in men compared with women, with a ratio of 2.8 per 100,000 individuals (P<0.05). In conclusion, the present study has revealed that, between 2004 and 2017, there was a slight decrease in the values of both CIR and ASIR of GC in Saudi Arabia.

Abstract
PURPOSE Malignancies of the upper gastrointestinal tract are rare in early-onset patients outside the hereditary genetic disorders. There are few reports describing adenocarcinoma of the esophagogastric junction (AEG) in extremely early-onset patients aged under 50 years old. The aim of this study was to describe the clinicopathological features and prognosis of adenocarcinoma of esophagogastric junction (AEG) in early-onset patients among three successive periods: 1975-1989 (period 1), 1990-2004 (period 2), and 2005-2017 (period 3). METHODS Between 1975 and 2017, data were extracted from the Surveillance, Epidemiology, and End Results database, and 18,278 patients with AEG were enrolled. Three age groups of patients were identified: < 50, 50-69, and ≥ 70 years of age. Clinicopathological characteristics and prognostic outcomes were reviewed and compared among three groups over three periods (1975-89, 1990-04, and 2005-2017). Multivariate Cox regression analysis was performed to adjust for covariate effects related to both overall survival (OS) and cancer-specific survival (CSS). RESULTS Among three age groups, early-onset patients were more likely to present with higher tumor grade, advanced nodal, and distant metastatic disease at diagnosis than other groups (p < 0.01 for both). In comparison to the older group, a higher proportion of patients in the early-onset group received chemotherapy and radiation treatment. After adjusting for covariates, early-onset patients had a better CSS and OS than elderly patients. CONCLUSIONS Early-onset AEG patients were more likely than other age groups to present with advanced disease upon diagnosis. However, the prognosis of early-onset patients was better than their older counterparts after adjustment for covariates. The dissimilarities in tolerance to treatment among early-onset, middle-aged, and elderly patients could be the reason for this difference.

Abstract
An increase trend and a bad prognosis toward gastric cancer (GC) in individuals <40 years have been observed over the past few decades. GC in Young adult needs further evaluation to identify clear risk factors for early screening and better prognosis. A total of 126 young adult patients with gastric cancer (individuals <40 years) (YG) were collected in Liaocheng hospital in China from Jan 2003 to Dec 2019. The overall median follow-up was 96.5 months (rang 1-192 months). Survival was determined by the Kaplan-Meier method and the difference in survival among different subgroups were assessed using the log-lank test. Correlations between risk factors and overall survival were assessed by univariate and multivariate Cox proportional hazards regression analysis. Advanced stage cancer at onset and undifferentiated histologic tumor type were the prominent clinicopathological features of YG. The 5-year overall survival of the YG was 31.7%. The 5-year survival of the YG differed from tumor staging and treatment methods. The 5-year survival was 100% in stage I group, 58.8% in stage II group, 22.6% in stage III group, and 8.3% in stage IV group respectively. The 5-year survival was 52.1% in the curative resection group versus 3.8% in the non-curative resection group. Multivariate analysis displayed that tumor staging (P = .002) and treatment method (P = .034) were 2 independent prognostic predictors for survival. GC in young adult patients have unique clinicopathological features. Upper gastrointestinal endoscopy should regularly perform for young adult especially those symptomatic patients. Early diagnosis and then proceed to a successful curative resection are vital for a better prognosis.

Abstract
Background Gastric cancer (GC) among adolescents and young adults (AYAs, aged 15-39 years) has limited data on clinicopathological characteristics and prognosis. This study aimed to compare the clinicopathological characteristics, perioperative outcomes, and long-term outcomes of AYAs and older adults (OAs, aged > 39 years) with GC who underwent curative gastrectomy. Methods From January 1994 to June 2019, patients with GC undergoing curative gastrectomy were enrolled and divided into AYA group and OA group. The clinicopathological characteristics, treatment variables, perioperative outcomes and long-term outcomes were compared between the two groups, both before and after propensity score matching (PSM). Results AYAs had fewer comorbid conditions and were more likely to be females, have normal carcinoembryonic antigen (CEA) levels, poorly differentiated tumors with perineural invasion, and receive adjuvant chemotherapy. AYA patients had lower incidence of postoperative complications and shorter length of postoperative hospital stay than OA patients. No significant differences in postoperative 30-day or 90-day mortality were observed between AYAs and OAs, both before and after PSM. In the entire cohort, AYAs had similar median overall survival (OS) to OAs. However, in the PSM cohort, AYAs had significantly shorter median OS. Young age (15-39 years) was an independent risk factor for OS in GC patients following gastrectomy. Conclusion The clinicopathological characteristics were significantly different between AYA and OA patients with GC. AYA patients with GC had worse long-term prognosis than OA patients, and young age was an independent risk factor for OS in GC patients following gastrectomy.

Abstract
Distant metastasis (DM) is relatively uncommon in T1 stage gastric cancer (GC). The aim of this study was to develop and validate a predictive model for DM in stage T1 GC using machine learning (ML) algorithms. Patients with stage T1 GC from 2010 to 2017 were screened from the public Surveillance, Epidemiology and End Results (SEER) database. Meanwhile, we collected patients with stage T1 GC admitted to the Department of Gastrointestinal Surgery of the Second Affiliated Hospital of Nanchang University from 2015 to 2017. We applied seven ML algorithms: logistic regression, random forest (RF), LASSO, support vector machine, k-Nearest Neighbor, Naive Bayesian Model, Artificial Neural Network. Finally, a RF model for DM of T1 GC was developed. The AUC, sensitivity, specificity, F1-score and accuracy were used to evaluate and compare the predictive performance of the RF model with other models. Finally, we performed a prognostic analysis of patients who developed distant metastases. Independent risk factors for prognosis were analysed by univariate and multifactorial regression. K-M curves were used to express differences in survival prognosis for each variable and subvariable. A total of 2698 cases were included in the SEER dataset, 314 with DM, and 107 hospital patients were included, 14 with DM. Age, T-stage, N-stage, tumour size, grade and tumour location were independent risk factors for the development of DM in stage T1 GC. A combined analysis of seven ML algorithms in the training and test sets found that the RF prediction model had the best prediction performance (AUC: 0.941, Accuracy: 0.917, Recall: 0.841, Specificity: 0.927, F1-score: 0.877). The external validation set ROCAUC was 0.750. Meanwhile, survival prognostic analysis showed that surgery (HR = 3.620, 95% CI 2.164-6.065) and adjuvant chemotherapy (HR = 2.637, 95% CI 2.067-3.365) were independent risk factors for survival prognosis in patients with DM from stage T1 GC. Age, T-stage, N-stage, tumour size, grade and tumour location were independent risk factors for the development of DM in stage T1 GC. ML algorithms had shown that RF prediction models had the best predictive efficacy to accurately screen at-risk populations for further clinical screening for metastases. At the same time, aggressive surgery and adjuvant chemotherapy can improve the survival rate of patients with DM.

Abstract
INTRODUCTION Cancers of unknown primary (CUP) are defined as histologically confirmed metastatic cancers that do not have an identified primary site of origin despite an appropriate diagnostic workup. Although accessibility to and quality of medical care influence diagnosis of cancer including CUP, previous studies describing CUP have generally been conducted in patients with various accessibilities to care. This study aimed to describe the demographic, histologic, and temporal trend characteristics of CUP patients in the DoD Cancer Registry of the Military Health System (MHS), which provides universal health care access, reducing the potential effects of accessibility to care on research results. MATERIALS AND METHODS The data were obtained from the DoD's Automated Central Tumor Registry (ACTUR), which collects cancer data from beneficiaries who were diagnosed or received treatment in the MHS. We described the demographic and histologic distributions in CUP patients aged 18 years or older diagnosed from 1987 to 2013. We calculated the proportion of CUP patients among all metastatic cancers and the most common histologic categories of those tumors. We then evaluated whether the proportion of histologic types changed over time. RESULTS CUP comprised 13.3% of all metastatic cancers in ACTUR during the study period. The majority of CUP within ACTUR was moderately and well-differentiated adenocarcinoma (51.3%) and poorly differentiated carcinomas (23.2%) followed by squamous cell carcinomas (12.5%). The percentages of CUP among metastasized cancers of the same histologic category ranged 12%-15% for moderately and well-differentiated adenocarcinomas, squamous cell, and poorly differentiated carcinomas, and 41%-46% for malignant neuroendocrine carcinomas and undifferentiated neoplasms. However, the percentages varied by sex, race, and age for certain pathologies. The proportion of CUP patients among all metastatic cancer patients has steadily declined from 22.4% to 8.3% from 1987 to 2013. CONCLUSION The proportion and trends of CUP in the ACTUR were generally consistent with other descriptive CUP studies. This study provides a description of CUP in a health care system with universal access in the USA and provides a foundation for future studies on CUP.

World J Gastroenterol 2023; 29:1090-1108. [PMID: 36844138 PMCID: PMC9950867 DOI: 10.3748/wjg.v29.i6.1090] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 12/11/2022] [Accepted: 01/05/2023] [Indexed: 02/10/2023] Open
Abstract
BACKGROUND The impact of racial and regional disparity on younger patients with gastric cancer (GC) remains unclear.
AIM To investigate the clinicopathological characteristics, prognostic nomogram, and biological analysis of younger GC patients in China and the United States.
METHODS From 2000 to 2018, GC patients aged less than 40 years were enrolled from the China National Cancer Center and the Surveillance Epidemiology and End Results database. Biological analysis was performed based on the Gene Expression Omnibus database. Survival analysis was conducted via Kaplan-Meier estimates and Cox proportional hazards models.
RESULTS A total of 6098 younger GC patients were selected from 2000 to 2018, of which 1159 were enrolled in the China National Cancer Center, and 4939 were collected from the Surveillance Epidemiology and End Results database. Compared with the United States group, younger patients in China revealed better survival outcomes (P < 0.01). For race/ethnicity, younger Chinese cases also enjoyed a better prognosis than that in White and Black datasets (P < 0.01). After stratification by pathological Tumor-Node-Metastasis (pTNM) stage, a survival advantage was observed in China with pathological stage I, III, and IV (all P < 0.01), whereas younger GC patients with stage II showed no difference (P = 0.16). In multivariate analysis, predictors in China involved period of diagnosis, linitis plastica, and pTNM stage, while race, diagnostic period, sex, location, differentiation, linitis plastica, signet ring cell, pTNM stage, surgery, and chemotherapy were confirmed in the United States group. Prognostic nomograms for younger patients were established, with the area under the curve of 0.786 in the China group and of 0.842 in the United States group. Moreover, three gene expression profiles (GSE27342, GSE51105, and GSE38749) were enrolled in further biological analysis, and distinctive molecular characteristics were identified in younger GC patients among different regions.
CONCLUSION Except for younger cases with pTNM stage II, a survival advantage was observed in the China group with pathological stage I, III, and IV compared to the United States group, which might be partly due to differences in surgical approaches and the improvement of the cancer screening in China. The nomogram model provided an insightful and applicable tool to evaluate the prognosis of younger patients in China and the United States. Furthermore, biological analysis of younger patients was performed among different regions, which might partly explain the histopathological behavior and survival disparity in the subpopulations.

Clinicopathological characteristics of early gastric cancer with different level of undifferentiated component and nomogram to predict lymph node metastasis. Front Surg 2023; 10:1097927.

Abstract
Background Few studies showed that mixed type early gastric cancer (EGC) relates to higher risk of lymph node metastasis. We aimed to explore the clinicopathological feature of GC according to different proportions of undifferentiated components (PUC) and develop a nomogram to predict status of lymph node metastasis (LNM) in EGC lesions. Methods Clinicopathological data of the 4,375 patients who underwent surgically resection for gastric cancer in our center were retrospectively evaluated and finally 626 cases were included. We classified mixed type lesions into five groups (M1:0% < PUC ≤ 20%, M2:20%<PUC ≤ 40%, M3:40%<PUC ≤ 60%, M4:60%<PUC ≤ 80%, M5:80%<PUC < 100%). Lesions with 0% PUC were classified as pure differentiated group (PD) and lesions with 100% PUC were classified as pure undifferentiated group (PUD). Results Compared with PD, LNM rate was higher in group M4 and group M5 (p < 0.05 after Bonferroni correction). Differences of tumor size, presence of lymphovascular invasion (LVI), perineural invasion and invasion depth also exist between groups. No statistical difference of LNM rate was found in cases who met the absolute endoscopic submucosal dissection (ESD) indications for EGC patients. Multivariate analysis revealed that tumor size over 2 cm, submucosa invasion to SM2, presence of LVI and PUC level M4 significantly predicted LNM in EGC. With the AUC of 0.899(P < 0.05), the nomogram exhibited a good discrimination. Internal validation by Hosmer-Lemeshow test showed a good fitting effect in model (P > 0.05). Conclusion PUC level should be considered as one of the predicting risk factors of LNM in EGC. A nomogram that predicts the risk of LNM in EGC was developed.

Comparisons of pathologic findings and outcomes of gastric cancer patients younger and older than 40: a propensity score matching study in a single center of Korea. JGH Open 2023; 7:118-127. [PMID: 36852144 PMCID: PMC9958344 DOI: 10.1002/jgh3.12860] [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: 03/09/2022] [Revised: 10/18/2022] [Accepted: 01/01/2023] [Indexed: 01/17/2023]
Abstract
Background and Aim Gastric cancer (GC) is one of the most common cancers worldwide, with a high incidence rate in Korean men. However, comparative studies are scarce on the pathologic findings and treatment effects of GC in patients aged less than 40 years. We evaluated the characteristics and pathologic findings of GC patients aged younger and older than 40 years. Methods We retrospectively analyzed 2307 patients diagnosed with GC between January 2010 and May 2018. Eighty-eight (3.8%) and 2219 (96.2%) patients were younger and older than 40 years, respectively. The patients were divided into younger (n = 70) and older (n = 62) age groups through propensity matching. Results Overall, compared to the younger group, the older group (n = 2219) had a significantly higher proportion of male patients (66.7% vs 39.8%; P < 0.001) and patients who underwent endoscopic submucosal dissection (ESD) (2.3% vs 23.1%; P < 0.001). However, young patients more often underwent operations compared to older patients (78.4% vs 60.1%; P = 0.001). In the propensity-matched group, older patients more often showed differentiated carcinoma, including well-differentiated (5.7% vs 11.3%) and moderately differentiated (1.4% vs 32.3%). However, younger patients more often showed signet ring cell carcinoma (SRC) (70.0% vs 25.8%). In multivariate analysis, Helicobacter pylori infection (odds ratio, 12.643; 95% confidence interval, 1.068-1449.665; P = 0.044) independently correlated with SRC risk. Conclusions Patients below 40 years were more likely to undergo surgery compared to ESD, and pathologic findings were more common in SRC. Therefore, more active screening and H. pylori eradication are needed even in patients aged less than 40 years.

Gastric cancer clinical characteristics and their altered trends in South China: An epidemiological study with 2,800 cases spanning 26 years. Front Oncol 2023; 13:976854. [PMID: 36824130 PMCID: PMC9942704 DOI: 10.3389/fonc.2023.976854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Accepted: 01/02/2023] [Indexed: 02/09/2023] Open
Abstract
BACKGROUND Gastric cancer (GC) is a serious threat to human health. The clinical GC characteristics in China may be impacted by changes in people's lifestyles and the promotion of early GC (EGC) screening. The present study aims to evaluate the recent trends of GC characteristics in South China and search for hazardous factors limiting the survival time of GC patients. METHODS Data on GC patients that were hospitalized in the Department of Digestive Center, the First Affiliated Hospital, Sun Yat-sen University, from 1994 to 2019 were collected and divided into two categories according to the time when the EGC screening began in China: the PRE group (previous 13 years, 1994-2006) and the PAS group (past 13 years, 2007-2019). RESULTS We found that, although the 5-year survival rate increased in the PAS group compared with the PRE group (P < 0.0001), patients with age ≥60 years or Borrmann type IV still had a worse prognosis. In the PAS group, the larger percentages of elderly patients and patients with Borrmann type IV in the lymphatic metastases (N1) group (41.0% vs. 51.1%, P = 0.0014) and stage IV subgroup (20.7% vs. 32.2%, P = 0.016), respectively, when compared with the PRE group, may have contributed to the poor outcome of GC. By comparing the odds ratio (OR) of 5-year overall survival (OS) in the two 13-year periods, female sex and T2 turned into risk factors because of a greater proportion of Borrmann type IV or elderly patients in the PAS group (OR = 0.983, 95% CI = 0.723-1.336 vs. OR = 1.277, 95% CI = 1.028-1.586 and OR = 1.545, 95% CI = 0.499-4.775 vs. OR = 2.227, 95% CI = 1.124-4.271, respectively). CONCLUSIONS Despite the GC epidemiology changes, the overall prognosis of GC patients has improved in South China. However, old age and Borrmann type IV are still the major restrictions affecting the survival of GC patients, a situation which calls for additional attention.

Specifics of Young Gastric Cancer Patients: A Population-Based Analysis of 46,110 Patients with Gastric Cancer from the German Clinical Cancer Registry Group. Cancers (Basel) 2022; 14:cancers14235927. [PMID: 36497406 PMCID: PMC9739447 DOI: 10.3390/cancers14235927] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Accepted: 11/28/2022] [Indexed: 12/02/2022] Open
Abstract
Introduction: 2−8% of all gastric cancer occurs at a younger age, also known as early-onset gastric cancer (EOGC). The aim of the present work was to use clinical registry data to classify and characterize the young cohort of patients with gastric cancer more precisely. Methods: German Cancer Registry Group of the Society of German Tumor Centers—Network for Care, Quality and Research in Oncology (ADT)was queried for patients with gastric cancer from 2000−2016. An approach that stratified relative distributions of histological subtypes of gastric adenocarcinoma according to age percentiles was used to define and characterize EOGC. Demographics, tumor characteristics, treatment and survival were analyzed. Results: A total of 46,110 patients were included. Comparison of different groups of age with incidences of histological subtypes showed that incidence of signet ring cell carcinoma (SRCC) increased with decreasing age and exceeded pooled incidences of diffuse and intestinal type tumors in the youngest 20% of patients. We selected this group with median age of 53 as EOGC. The proportion of female patients was lower in EOGC than that of elderly patients (43% versus 45%; p < 0.001). EOGC presented more advanced and undifferentiated tumors with G3/4 stages in 77% versus 62%, T3/4 stages in 51% versus 48%, nodal positive tumors in 57% versus 53% and metastasis in 35% versus 30% (p < 0.001) and received less curative treatment (42% versus 52%; p < 0.001). Survival of EOGC was significantly better (five-years survival: 44% versus 31% (p < 0.0001), with age as independent predictor of better survival (HR 0.61; p < 0.0001). Conclusion: With this population-based registry study we were able to objectively define a cohort of patients referred to as EOGC. Despite more aggressive/advanced tumors and less curative treatment, survival was significantly better compared to elderly patients, and age was identified as an independent predictor for better survival.

Abstract
Gastric cancer (GC) is the fourth most common cancer in the world and the second most common cancer in China. In this study, we compared the clinicopathological features and prognosis of GC between young and old patients after curative resection. Six hundred and eighty-six patients with GC resected were divided two groups according to patient age: Younger GC patients ≤40 years of age (YGC, n = 52) and older GC patients >40 years of age (OGC, n = 634). The YGC group had 52 (7.6%) patients in total 686 GC patients. YGC patients was predominant in women (53.8% vs 26.5%) compared with OGC patients. 5-year overall survival exhibited differences in tumor sites, tumor sizes, macroscopic types, T staging, N staging, rate of N staging (rN), tumor node metastasis staging, scope of gastrectomy, radical degree, and lymphatic vascular invasion within each of YGC and OGC group. Univariate analysis of the clinical factors affecting overall survival in YGC group revealed the significant differences in tumor size, macroscopic types (except Borrmann), T staging (except T2), N staging (N3a and N3b), rN, tumor node metastasis staging (III), scope of gastrectomy, radical degree, and lymphatic vascular invasion. Gender, N staging, rN, radical degrees were the independent prognostic factors of younger patients with GC. Similar results were found in the OGC groups. The significant differences in radical degree and lymphatic vascular invasion were found between male and female patients in YGC group. Similar results were found in the OGC groups. Our results showed that YGC patients differ from OGC patients in predominance of women. Gender, N staging, rN, radical degrees were independent risk factors for the prognosis in YGC patients.

Abstract
OBJECTIVES To evaluate and compare the burden of gastric cancer in adolescents and young adults (GCAYA) among China, South Korea, Japan and the USA, four countries with similar or different rates of gastric cancer (GC) incidence, development levels and cancer control strategies. DESIGN This population-based observational study collected the epidemiological data of GCAYA from the Global Burden of Diseases Study 2019. The trend magnitude and directions over time for incidence and mortality of GCAYA were analysed and compared among four countries. MAIN OUTCOMES AND MEASURES Outcomes included new cases, deaths, mortality-to-incidence ratios (MIRs), disability-adjusted life years, and their age-standardised rates and estimated annual percentage changes (AAPCs). RESULTS There were 49 008 new cases and 27 895 deaths from GCAYA in 2019, nearly half of which occurred in China. The AAPCs for the age-standardised incidence and mortality rate were 0.3 (-0.1 to 0.7), -3.6 (-3.7 to -3.4), -3.2 (-3.8 to -2.6), -0.1 (-0.6 to 0.5) and -2.0 (-2.3 to -1.6), -5.6 (-6.2 to -5.0), -4.4 (-4.7 to -4.1), -0.7 (-1.0 to -0.3) in China, South Korea, Japan and the USA, respectively. The incidence rate for females in the USA rose by 0.4% annually. GC ranks fifth, first, fourth and ninth in China, South Korea, Japan and the USA regarding burdens caused by cancer in adolescents and young adults. The MIRs declined constantly in South Korea and China, and the MIR in the USA became the highest in 2019. CONCLUSIONS Although not covered by prevention and screening programmes, variations in disease burden and time trends may reflect variations in risk factors, cancer control strategies and treatment accessibility of GC among the four countries. Investigating the reasons behind the varying disease burden and changing trends of GCAYA across countries will inform recommendations for prevention measures and timely diagnosis specific to this underserved population to further decrease the GC burden.

Abstract
PURPOSE The proportion of gastroesophageal junction adenocarcinoma is increasing. This study evaluated trends in early-onset gastric and esophageal cancers and compared socioeconomic and clinical characteristics between early-onset versus late-onset disease. MATERIALS AND METHODS We included all patients with gastric and esophageal cancer from 2004 to 2015 from the National Cancer Database. Patients were categorized by age < 50, 50-69, and ≥ 70 years. Differences in pathologic and socioeconomic factors between early-onset and late-onset cancers were assessed by using chi-square test. The effects of demographic and socioeconomic factors on overall survival (OS) were assessed using Cox models. RESULTS The proportion of patients with early-onset gastric cancer increased from 23.9% in 2004-2006 to 26.2% in 2013-2015, whereas the proportion of early-onset esophageal cancer decreased from 27.3% in 2004-2006 to 23.1% in 2013-2015. For both malignancies, the early-onset group was more likely to be Black or Hispanic and more likely to be diagnosed with stage IV cancer. Black patients had the worst median OS in both malignancies. In gastric cancer, within the Black patient group, patients experienced worse OS if they had government insurance versus private insurance (hazard ratio 1.2; 95% CI, 1.1 to 1.3; P value < .0001) or if they were in the lowest community median income category versus the highest category (hazard ratio 1.2; 95% CI, 1.1 to 1.3; P value < .0001). CONCLUSION Early-onset gastric cancer is increasing, whereas early-onset esophageal cancer is declining. Early-onset gastric cancer disproportionately affects non-White patients, particularly Hispanic patients. Black patients have worse outcomes compared with other races for both gastric and esophageal cancer.

Abstract
Gastric cancer is one of the most common and deadly cancer types worldwide, which brings millions of dollars of economic loss each year. Patients diagnosed with early-onset gastric cancer were reported to have a worse prognosis compared to other gastric cancer patients, while the mechanisms behind such phenomenon are unknown. To identify age-dependent somatic alternations in gastric cancer, next-generation sequencing targeting 425 genes was performed on 1688 gastric tumor tissues and corresponding plasma samples. In our study, the microsatellite instability (MSI) and chromosomal instability score (CIS) values increased along with the age of patients, which indicates that older patients display a less genomic stability pattern. The differences of somatic alternations between young and old groups were compared. Somatic mutations CDH1 and copy number gains of FGFR2 were identified to enrich in the younger gastric cancer patients, which may contribute to the worse prognosis of early-onset gastric cancer patients.

Abstract
BACKGROUND Early-onset pancreatic cancer (≤50 years, EOPC) is uncommon. This study aims to characterize the clinical and survival characteristics of EOPC in comparison to late-onset pancreatic cancer (>50 years, LOPC). METHODS We retrospectively investigated consecutive PC patients treated at our institution between 2010 and 2019. We analyzed and compared clinicopathological characteristics, treatments, and outcomes of EOPC and LOPC. RESULTS Of 1646 PC patients identified (768 resectable/borderline resectable; 248 locally advanced; 630 metastatic), 127 (8%) had EOPC. Current smoking and heavy drinking were associated with EOPC. EOPC presented at a more advanced stage and had higher neutrophil-to-lymphocyte ratios than LOPC. Survival outcomes were similar between the two groups, both in the entire cohort and in each resectability group. In patients undergoing resection, EOPC tended to have a higher N stage (p = 0.099) and had a higher pathological stage (stage IV, 20% vs. 7%, p = 0.005) and a lower rate of macroscopically curative resection (80% vs. 93%, p = 0.006). Liver recurrence was more commonly observed in EOPC (42% vs. 23%, p = 0.015). In the metastatic cohort, combination chemotherapy regimens were more frequently administered in EOPC as first-line treatment (79% vs. 64%, p = 0.028). Both median PFS (4.4 vs. 5.3 months, p = 0.647) and OS (11.5 vs. 9.5 months, p = 0.183) were not significantly different between the two groups. CONCLUSIONS EOPC presented with a more aggressive tumor biology. Survival outcomes were similar to LOPC due to more intensive treatment.

Abstract
Treatments for early-onset gastric cancer (EOGC) patients are rarely included in clinical trials, resulting in an unclear impact on survival. This study aimed to investigate the treatment patterns of EOGC patients and their impact on survival. Based on the Surveillance, Epidemiology, and End Results database, we conducted a retrospective analysis of 1639 EOGC patients (< 50 years) diagnosed between 2010 and 2018. Patients with larger tumours, distant metastasis, and AJCC TNM stage in IV were prone to receive nonsurgical treatment. Patients treated with surgery alone had a better prognosis than those receiving SROC or SCRT or nonsurgical treatment. However, analyses stratified by histological type, tumour size and TNM stage showed that patients did not benefit more from SROC and SCRT than from surgery alone. Similar results were observed in the stratified Cox regression risk analysis. Patients who received nonsurgical treatment had the highest risk of overall death [hazard ratio (HR) = 2.443, 95% confidence interval (CI) 1.865–3.200, P < 0.001]. This study indicated that additional radiotherapy, chemotherapy or chemoradiotherapy did not provide a coordinated survival benefit to EOGC patients.

Abstract
PURPOSE With the aging of society, the mean age of patients with gastric cancer (GC) in Japan has increased. However, there are few documented outcomes for young patients with stage IV GC. We investigated the clinical characteristics and prognosis of such patients aged < 40 years using a dataset from an integrated population-based cohort study. METHODS We conducted this multicenter population-based cohort study to determine whether earlier onset of GC was a poor prognostic factor. We enrolled patients with metastatic GC aged < 40 years (young group) and those aged between 60 and 75 years (middle-aged group). Patients were histologically diagnosed as having gastric adenocarcinoma. We evaluated the overall survival (OS) of both groups and the hazard ratio (HR) for OS based on age. The adjusted HR with 95% confidence interval (CI) was evaluated using the Cox proportional hazards model after adjusting for confounding factors, including sex, histology, number of metastatic lesions, surgical resection, and chemotherapy. RESULTS This study enrolled 555 patients. The patients were classified into the young (n = 20) and the middle-aged group (n = 535). The median OS durations were 5.7 and 8.8 months in the young and middle-aged groups, respectively (p = 0.029). The adjusted HR (95% CI) of the young group was 1.88 (1.17-3.04, p = 0.009). CONCLUSION Age was an independent prognostic factor in patients with stage IV GC. Further studies investigating the genomic characteristics of GC and exploring more effective chemotherapeutic agents are required.

Abstract
Purpose The purpose of the current study was to compare the postoperative complications, overall survival and disease-free survival in young and old gastric cancer patients after gastrectomy using propensity score matching (PSM). Methods Adult patients (aged ≥ 18 years) who underwent gastrectomy for gastric cancer in a single clinical center from January 2013 to December 2017 were enrolled continuously for retrospective analysis. To minimize the selection bias between the young and old groups, the PSM was conducted in this study. Results A total of 558 patients were included in this study, with 51 patients in the young group (aged ≤ 45 years) and 507 patients in the old group (aged > 45 years). After 1:1 matching according to PSM, 51 patients in the young group were matched to 51 patients in the old group. After PSM, there was no difference in the baseline information. In terms of short-term outcomes, no difference was found in operation time (P = 0.190), intraoperative blood loss (P = 0.336), retrieved lymph nodes (P = 0.948), blood transfusion (P = 0.339), postoperative hospital stay (P = 0.194), or postoperative complications (P = 0.477) between the two groups. For overall survival, no statistically significant difference was found in all stages (P = 0.383), stage I (P = 0.431), stage II (P = 0.875) or stage III (P = 0.446) gastric cancer. Furthermore, regarding disease-free survival, no differences were found between the two groups in all stages (P = 0.378), stage I (P = 0.431), stage II (P = 0.879) or stage III (P = 0.510) gastric cancer. Conclusion Age might not be an independent prognostic factor for short-term outcomes, OS, or DFS in gastric cancer patients who underwent gastrectomy. The pTNM stage of GC might be an independent prognostic factor for OS and DFS.

J Gastroenterol Hepatol 2021; 36:2834-2840. [PMID: 34033134 DOI: 10.1111/jgh.15558] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 03/26/2021] [Accepted: 05/23/2021] [Indexed: 12/14/2022]
Abstract
BACKGROUND AND AIM Obesity was suggested to increase the incidence of gastric cancer (GC) in women, but results from previous studies were inconsistent. We investigated the relationship between obesity and the risk of GC according to menopausal status. METHODS We enrolled 1 418 180 premenopausal and 4 854 187 postmenopausal women aged ≥ 40 years using the Korean National Health Insurance System Cohort (2009-2014). We calculated hazard ratios (HRs) and 95% confidence intervals (CIs) for GC incidence according to body mass index (BMI) and waist circumference (WC) using the Cox proportional hazards models. RESULTS During the mean follow-up period of 7.2 years, 42 441 women were newly diagnosed with GC. Compared with the group with BMI 18.5-22.9 kg/m2 , the adjusted HRs (95% CIs) for GC in the groups with BMI < 18.5, 23-24.9, 25-29.9, and ≥ 30 kg/m2 were 1.12 (0.95-1.33), 0.96 (0.89-1.04), 1.02 (0.94-1.11), and 0.99 (0.83-1.18), respectively, for premenopausal women and 1.07 (1.00-1.14), 1.01 (0.99-1.04), 1.03 (1.00-1.05), and 1.11 (1.10-1.16), respectively, for postmenopausal women. Compared with the group with WC 65-74.9 cm, the adjusted HRs (95% CIs) for GC for the groups with WC < 65, 75-84.9, 85-94.9, and ≥ 90 cm were 1.00 (0.88-1.15), 1.03 (0.96-1.11), 1.10 (0.99-1.22), and 1.02 (0.81-1.27), respectively, for premenopausal women and 1.01 (0.94-1.09), 1.01 (0.99-1.04), 1.09 (1.06-1.13), and 1.14 (1.09-1.19), respectively, for postmenopausal women. CONCLUSIONS We found a positive association between the highest BMI and WC category and risk of GC in postmenopausal women; however, such an association was not evident in premenopausal women.

Abstract
Background Accurate staging plays a pivotal role in cancer care. The lymph node (LN) ratio (LNR) and the log odds of positive LNs (LODDS) have been suggested as alternatives to the N staging since the TNM system has the risk of stage migration. The prognostic significance of LNR and LODDS in young patients with gastric cancer (GC) has not been reported. This study aims to investigate the correlations between LNR and LODDS and survival of young patients with GC, and compare the predictive performance of these LN staging methods. Methods GC patients before the age of 40 from 2004 to 2016 in the Surveillance, Epidemiology and End Results database were enrolled. The prognostic evaluation of the N factor, LNR and LODDS was compared using the time-dependent receiver operating characteristic (ROC) analysis, area under the curve (AUC), C-index and Akaike information criterion (AIC). Results Multivariate survival analysis identified that the LNR and LODDS were significantly independent prognostic indicators for overall survival (OS) in young patients with GC and in the subgroups comprised of patients with ≤15 LNs examined. The time-dependent ROC curves of the LNR and LODDS were continuously superior to that of the N factor in predicting OS during the observation period. And the AUCs revealed that the predictive accuracy of the LNR and LODDS was remarkably superior to the N factor at 1 and 3 years (P<0.05). The model incorporating LNR or LODDS had higher C-index and lower AIC when comparing to the model incorporating the N factor. Conclusions The LNR and LODDS improve accuracy of survival risk prediction in young patients with GC when comparing to the N factor. These two novel LN classification methods should be considered as alternatives to the N staging for the prognostic prediction of young patients with GC.

Abstract
Purpose The aim of this retrospective study was to probe into clinicopathological features and prognosis of early-onset gastric cancer (EOGC) patients aged ≤ 45 years old. Methods This study selected 154 young gastric cancer patients aged ≤ 45 years old and 158 elderly gastric cancer patients aged > 50 years old admitted to West China Hospital of Sichuan University in 2009-2019 as the research object. These patients were further divided into two groups according to whether tumor can be resected radically. The following parameters were analyzed: age, gender, helicobacter pylori (HP) infection status, Her-2 status, pathological type and stage, chemotherapy, tumor differentiation degree, overall survival (OS). Results More than 3,000 patients with gastric carcinoma were screened, and 154 young gastric cancer patients aged ≤ 45 years old were identified as EOGC. Among them, the number of female patients in EOGC group was significantly higher than that of males, accounting for 63.6%. In addition, EOGC were associated with diffuse Laur´en type and poorly differentiated tumors. Interestingly, the Kaplan-Meier method showed that the OS of unresectable EOGC group was significantly lower than that of unresectable LOGC group (P = 0.0005) and chemotherapy containing paclitaxel tended to be more effective in the young people (P = 0.0511). Nevertheless, there was no significant difference in OS between young and elderly patients with gastric cancer in the radical resection group (P = 0.3881). Conclusion EOGC patients have a worse prognosis than late-onset gastric cancer (LOGC) patients with advanced unresectable gastric cancer. Palliative surgery or chemotherapy containing paclitaxel may improve the OS of unresectable young individuals with gastric cancer. Additional randomized controlled trials are required for guiding clinical practice.

Abstract
Mortality difference by age, sex, body mass index (BMI) in gastric cancer (GC) has been controversial. We evaluated sex-specific mortality by age and BMI. A total of 5961 patients diagnosed with GC from 2005 to 2013 in a single tertiary center were included and were followed until December 2017. The plot in goodness-of-fit-test by sex was crossed, so we performed sex-specific analysis. Overall mortality was lower in women than in men (adjusted hazard ratio [aHR], 0.72). Favor outcomes in women compared to men were observed among patients older than 60 yr (aHR, 0.64; 95% CI, 0.56-0.74), a BMI less than 25 kg/m2 (aHR, 0.69; 95% CI, 0.61-0.79), and stage I (aHR, 0.46; 95% CI, 0.38-0.56). In sex-specific analysis, mortality increased in age older than 60 yr in men, whereas it increased in both extreme ages (<40 yr and ≥ 70 yr) in women. Mortality by BMI was lowest at BMI of 25-29.9 kg/m2 and gradually increased according to decrease of BMI in men; aHR, 1.24 (23-24.9 kg/m2), 1.44 (18.5-22.9 kg/m2), and 2.54 (BMI<18.5 kg/m2). However, mortality decreased in patients with BMI ≥ 30 kg/m2 (aHR, 0.46) in women. The sex discrepancies in GC mortality by age and BMI suggest the need for sex-specific approaches to prognostic prediction.

Front Oncol 2021; 11:595421. [PMID: 34307116 PMCID: PMC8297973 DOI: 10.3389/fonc.2021.595421] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2020] [Accepted: 05/21/2021] [Indexed: 12/29/2022] Open
Abstract
Background Despite the implementation of the 8th American Joint Committee on Cancer (AJCC) TNM staging system for gastric cancer (GC) in 2017, it still holds a significant level of stage migration which affects patients’ proper classification and accurate prognosis. Here, to reduce this effect, we evaluated the prognostic value of a lymph node ratio (LNR) and established a novel tumor–ratio–metastasis (TRM) staging system. Method The data of 15,206 GC patients from the Sun Yat-sen University Cancer Center (Training set; n=2,032) and the US Surveillance, Epidemiology, and End Results (SEER) database (Validation set; n=13,174) were analyzed. The training set was classified into 5 LNR categories, based on which the novel TRM staging system was constructed. The overall survival (OS) between the TRM and AJCC TNM systems was compared in the training set and validated in the validation set. The likelihood ratio x2, liner trend x2, C-index, and Akaike information criterion (AIC) values were used to measure the discriminatory ability between the two different staging systems. Decision curve analyses (DCAs) were conducted to test the clinical value of the two staging systems. Result The patients were classified into the following categories: LNR0: 0%, LNR1: 0%<LNR ≤ 10%, LNR2: 10%<LNR ≤ 25%, LNR 3a: 25%<LNR ≤ 60%, and LNR 3b: LNR>60%. Univariate analyses demonstrated that the log-rank x2 of the LNR stage (Training/Validation set: x2 = 463.1/2880.8) was larger than the AJCC pN stage (Training/Validation set: x2 = 281.5/2240.8). For both the training set and validation set, stratified analyses using the Kaplan-Meier method identified significantly heterogeneous OS in every pN category but only one using the LNR. The TRM staging system had higher likelihood ratio x2, liner trend x2, C-index and smaller AIC values than the TNM system. Conclusion The TRM staging system demonstrated improved homogeneity and discriminatory ability in predicting the prognosis of GC patients compared with the AJCC TNM staging system.

Abstract
Background Alternative splicing (AS), e.g. the tandem alternative polyadenylation (TAPA), has emerged as major post-transcriptional modification events in human disease. However, the roles of the AS and TAPA in early-onset gastric cancer (EOGC) have not been revealed. Methods The global AS profiles of 80 EOGC patients were analyzed. The EOGC-specific AS events (ESASs) were identified in both the EOGC and adjacent non-tumor tissues. The functional enrichment analysis, Splicing network, Alternative Polyadenylation (APA) core factor network, and cell abundancy analysis were performed. Furthermore, the landscapes of the AS events in the varied subtypes of the EOGC patients were evaluated. Results Overall, 66,075 AS events and 267 ESASs were identified in the EOGC. Furthermore, 4809 genes and 6152 gene isoforms were found to be aberrantly expressed in the EOGC. The Gene Ontology (GO) and Kyoto Encyclopedia of Gene and Genome (KEGG) pathway analyses showed that the significant pathway alterations might exist in these AS events, genes, and gene isoforms. Moreover, the Protein-protein interaction (PPI) network analysis revealed that the UBC, NEK2, EPHB2, and DCTN1 genes were the hub genes in the AS events in the EOGC. The immune cell infiltration analysis indicated a correlation between the AS events and the cancer immune microenvironment. The distribution of the AS events in varied EOGC subtypes, protein phosphorylation and glycosylation was uneven. Conclusion The study highlighted the vital roles of the AS in the EOGC, including modulating the specific protein modification and reshaping the cancer immune microenvironment, and yielded new insights into the diagnosis of the EOGC as well as cancer treatment.

Abstract
BACKGROUND Gastric cancer is a common cancer in China. This project investigated the disease burden of gastric cancer from 1990 to 2019 in China and globally. METHODS The global age-standardized rates (ASRs) were extracted from the Global Burden of Disease. Moreover, the estimated annual percentage changes (eAPCs) in the ASRs of incidence (ASIR), mortality (ASMR), and disability-adjusted life-years (DALYs) were calculated to determine the trends by countries and regions. RESULTS In China, the ASIR declined from 37.56 to 30.64 per 100,000 and the ASMR declined from 37.73 to 21.72 per 100,000. The global ASIR decreased from 22.44 to 15.59 and the ASMR declined from 20.48 to 11.88 per 100,000 persons from 1990 to 2019. The ASIR was the lowest in Malawi (3.28 per 100,000) and the highest in Mongolia (43.7 per 100,000), whereas the ASMR was the lowest in the United States of America (3.40 per 100,000) and the highest in Mongolia (40.04 per 100,000) in 2019. The incidence of early-onset gastric cancer increased in China. The DALYs attributed to gastric cancer presented a slight decrease during the period. China had a higher mortality/incidence ratio (0.845) and 5-year prevalence (27.6/100,000) than most developed countries. CONCLUSION China presented a steady decline in the incidence and mortality rates for gastric cancer. The global ASIR, ASMR, and DALYs showed a slight rise decrease. Different patterns of gastric cancer rates and temporal trends have been identified in different geographical regions, indicating that specific strategies are needed to prevent the increase in some countries.

Risk factors for lymph node metastasis in early gastric cancer without lymphatic invasion after endoscopic submucosal dissection. Eur J Surg Oncol 2021; 47:3059-3063.

Abstract
BACKGROUND Lymphatic invasion (LI) is a potent risk factor for lymph node metastasis (LNM) in early gastric cancer (EGC) after endoscopic submucosal dissection (ESD). However, there are also other risk factors for LNM. Hence, to identify the need for additional surgery in some case of EGC without LI, the present study aimed to identify the risk factors for LNM in patients with EGC without LI. METHODS Data from 2284 patients diagnosed with EGC who underwent curative surgery at National Cancer Center in Korea from January 2012 to May 2019 were collected. The clinicopathological characteristics of patients with EGC without LI were compared on the basis of LNM status. RESULTS There were 339 (17.1%) and 1648 (82.9%) patients with and without LI respectively. Among these patients with and without LI, 118 (34.8%) and 91 (5.5%) patients presented with LNM, respectively. In patients with EGC without LI, tumor size larger than 3 cm (OR = 2.12, 95% CI = 1.22-3.68; p = 0.007), submucosal invasion (OR = 4.14, 95% CI = 2.57-6.65; p < 0.001), and undifferentiated histologic type (OR = 2.33, 95% CI = 1.45-3.76; p < 0.001) were significant risk factors for LNM. Rates of LNM in patients meeting absolute, expanded, and beyond expanded criteria without LI were 0%, 1.5% (OR = 3.27, 95% CI = 0.18-59.41; p = 0.423), and 7.3% respectively. When the expanded criteria were divided into four subtypes patients with EGC, without LI within each subtype did not show significant risk of incidence of LNM compared to the absolute criteria. CONCLUSIONS The current expanded criteria for endoscopic resection (ER) are tolerable in cases without LI, even though minimal risk LNM exists. Therefore, additional surgery may not be needed for patients meeting expanded criteria for ER.
