Abstract
Burkitt lymphoma is a highly aggressive and rapidly growing B cell non-Hodgkin lymphoma with heterogeneous pattern of manifestations. We present a rare case of a 39-year-old immunocompetent male with double localization of Burkitt lymphoma: gastroduodenal and ileal tract. The gastric location is extremely rare, and the association with another site is unusual with only few reports in the literature. Imaging modalities play a crucial role in correct diagnosis as it can manifest as a focal mass or as segmental wall thickening. Radiologists should recognize common and uncommon presentations and sites of Burkitt lymphoma given the urgency of potential treatment, in order to improve the patient's prognosis.

Abstract
Langerhans cell histiocytosis (LCH) of the stomach is rare. Moreover, it is usually found in pediatric patients with systemic diseases and may be associated with a poor prognosis. Solitary gastric LCH in adults is extremely rare and is often misdiagnosed or missed. The aim of our study was to review cases of gastric LCH and explore the characteristics of the disease further. A retrospective study of all patients admitted with solitary gastric LCH was conducted between 2013 and 2023. Clinical manifestations, endoscopic and pathological features, immunophenotypes, and molecular changes were collected from medical records. We examined four cases (one female, three males) of gastric LCH. The affected patients were between 33 and 70 years of age. Endoscopically, three patients presented with a solitary polyp or elevated lesions, whereas one patient showed no abnormalities. Under a microscope, all cases showed abnormal proliferation of histiocytoid cells infiltrating in a nested or sheet-like fashion. The tumor cells were medium-sized, with a slightly eosinophilic cytoplasm, irregular or renal-shaped nuclei, folded nuclear membranes, visible nuclear grooves, and the infiltration of inflammatory cells in the background. Immunohistochemically, all lesions expressed CD1a, S-100, langerin, and cyclinD1. One case showed diffuse BRAF V600E positivity. Follow-up data were available for all patients from 4 to 36 months, and all patients were alive without recurrence or progress at the time of manuscript preparation. Combined with previously reported data, solitary adult gastric LCH is more common in male patients, most of whom are asymptomatic or exhibit only mild gastrointestinal symptoms, with a good prognosis. Endoscopy often reveals solitary polyps or protruding lesions; rare cases may progress to multifocal/multisystem lesions, necessitating long-term close follow-up.

Abstract
Cirrhosis is associated with a high morbidity and mortality. One of the most serious and unpredictable complication of cirrhosis, with a high mortality rate, is bleeding from esophagogastric varices. Endoscopic screening of varices followed by primary prophylactic treatment with beta blockers or band ligation in the presence of large esophageal varices will reduce the variceal bleeding rates and thereby reduce mortality risks in those with advanced cirrhosis. There is a paucity of data on primary prophylaxis of gastric varices but secondary prophylaxis includes glue injection, balloon-occluded retrograde transvenous obliteration, or transjugular intrahepatic portosystemic shunting with coil embolization.

Abstract
The clinical presentation of enteric duplication cysts is dependent on the location of the cyst with symptoms varying from nausea and vomiting to abdominal distension, pain and perforation. Four patients were identified who were diagnosed with enteric duplication cysts within the period from 2019 to 2023. Three of the patients presented with signs of intestinal obstruction-abdominal distension and pain, while one had an antenatally detected abdominal mass. There were three boys and one girl with ages ranging from 4 months to 14 years. Three cases of ileal and one case of caecal duplication cyst were reported. Most of the cases showed ileal/caecal mucosa while one case demonstrated ectopic gastric mucosa. The treatment of these cysts includes surgical excision. Although radiological investigations help in arriving at a provisional diagnosis, the final diagnosis can be confirmed only after histopathological examination. Early treatment prevents complications and results in a good prognosis for the patient.

Abstract
Gastric cancer (GC) is a malignant tumor with poor prognosis. Studies have shown that cysteine-rich secretory protein LCCL domain containing 1 (CRISPLD1) is associated with tumor progression. However, its role in GC is unclear. The present study aimed to determine the pathogenic mechanism of CRISPLD1 in GC. Analysis of public databases revealed high mRNA expression of CRISPLD1 in GC, which was associated with poor prognosis. Additionally, CRISPLD1 expression levels showed significant correlations with T stage, overall survival events, and stage. Knockdown of CRISPLD1 reduced cell proliferation, invasion, and migration. Furthermore, CRISPLD1 knockdown decreased intracellular calcium levels in GC cells and inhibited the phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K)-protein kinase B (AKT) signaling pathway. Treatment with an AKT activator reversed the inhibitory effect of CRISPLD1 knockdown on GC cell migration and invasion. Our findings suggest that CRISPLD1 promotes tumor cell progression in GC by mediating intracellular calcium levels and activating the PI3K-AKT pathway, highlighting CRISPLD1 as a potential therapeutic target for GC.

Abstract
BACKGROUND The Alcian blue (AB) and periodic acid Schiff (PAS) stains are representative mucus markers in gastric signet ring cell carcinoma (SRCC). They are low-cost special staining methods used to detect acidic mucus and neutral mucus, respectively. However, the clinical importance of the special combined AB and PAS stain is unclear. AIM To investigate AB expression, PAS expression and the AB-to-PAS (A/P) ratio in gastric SRCC patients and to assess patient prognosis. METHODS Paraffin-embedded sections from 83 patients with gastric SRCC were stained with AB and PAS, and signet ring cell positivity was assessed quantitatively. Immunohistochemical staining for Ki67, protein 53 (P53) and human epidermal growth factor receptor 2 (HER2) was performed simultaneously. The cancer-specific survival (CSS) rate was estimated via Kaplan-Meier analysis. Cox proportional hazards models were used for univariate and multivariate survival analyses. RESULTS Kaplan-Meier survival analysis revealed that the 3-year CSS rate was significantly greater in the high-PAS-expression subgroup than in the low-PAS-expression subgroup (P < 0.001). The 3-year CSS rate in the A/P ≤ 0.5 group was significantly greater than that in the A/P > 0.5 group (P = 0.042). Univariate Cox regression analysis revealed that the factors affecting prognosis included tumor diameter, lymph node metastasis, vessel carcinoma embolus, tumor stage, the A/P ratio and the expression of Ki67, P53 and the PAS. Cox multivariate regression analysis confirmed that low PAS expression [hazard ratio (HR) = 3.809, 95% confidence interval (CI): 1.563-9.283, P = 0.003] and large tumor diameter (HR = 2.761, 95%CI: 1.086-7.020, P = 0.033) were independent risk factors for poor prognosis. CONCLUSION A/P > 0.5 is potentially a risk factor for prognosis, and low PAS expression is an independent risk factor in the prognosis of gastric SRCC. PAS expression and the A/P ratio could help in predicting the clinical prognosis of patients with SRCC.

Abstract
BACKGROUND AND AIMS With the continuous development of endoscopic technology, endoscopic resection (ER) has gradually become an optional method for the treatment of gastric gastrointestinal stromal tumors (GISTs). However, studies with a large sample or a long follow-up are lacking. Therefore, this research aims to evaluate the efficacy and safety of ER for gastric GISTs in the real-world setting with more than 300 enrolled patients and a follow-up period longer than 45 months. METHODS From January 2013 to February 2023, 409 patients with a pathological diagnosis of GISTs after ER were retrospectively enrolled in this study. After excluding 86 patients with non-gastric GISTs, we assessed 323 patients with gastric GISTs. The main outcome measures were en bloc resection, complete resection, residual disease, recurrence, and complications. RESULTS There were 194 (60.06%) females and 129 (39.94%) males, and the median age of the included patients was 58 years (51, 63). The median tumor size was 15.0 (10.0, 20.0) mm. According to the modified NIH criteria, 246 (75.85%) patients were classified as very low risk, 62 (19.20%) were classified as low risk, 12 (3.72%) were classified as moderate risk, and 3 (0.93%) were classified as high risk. A total of 287 (88.85%) patients achieved en bloc resection, and 287 (88.85%) also achieved complete resection. Only one patient showed residual and no recurrent lesions were noted during the follow-up. Regarding complications, three patients had complications, with a complication rate of 0.93%, and no severe complications requiring surgical intervention occurred. CONCLUSION ER is an appropriate alternative method for the treatment of gastric GISTs, with an en bloc resection rate of 88.85% and a complication rate of 0.93%. No recurrence was noted during follow-up, even for GISTs with piecemeal resection.

Abstract
Gastric dysplasia is defined as an unequivocally neoplastic epithelium. Dysplastic lesions are characterized by cellular atypia reflective of abnormal differentiation and disorganized glandular architecture. The last few years have been marked by a refinement of the prognosis and risk of progression of gastric dysplasia and the recognition of novel morphologic patterns of dysplasia. Determination of the correct diagnosis and grade of dysplasia are critical steps since it will be predicting the risk of malignant transformation and help tailor appropriate surveillance strategy. This review describes the morphologic characteristics of conventional dysplasia and nonconventional gastric dysplasia that have been more recently characterized.

Abstract
Feedstuffs are often recommended to mitigate potential damage from acid associated with equine squamous gastric disease (ESGD). In acidic conditions, pectin alters its structure to one like mucus and binds the stomach mucosa, whilst alfalfa has a strong intrinsic acid buffering capacity. The study aimed to determine whether feeding a commercial beet pulp/alfalfa/oat fibre mix aids ESGD healing and/or prevention of recurrence. Ten adult horses with naturally occurring ESGD were included. All animals were treated with omeprazole as per the attending veterinarian's recommendation and randomly allocated to also be fed a commercial beet pulp/alfalfa/oat fibre mix (1Kg/horse divided into 2 meals/day; n=5) or no additional feed (n=5) for one month. Gastroscopy was then repeated to assess response to therapy. If the ESGD had healed, omeprazole therapy was discontinued, and the commercial feed given to all horses for a further month. Gastroscopy was repeated to determine ESGD recurrence. The mean (±SD) age of the horses was 11.6 (±3.8) years; 4 mares and 6 geldings; various breeds were represented; and the median (range) initial ESGD grade was 2 (2-4). ESGD had healed (grade 0/4) in all animals after one month. After a further month, ESGD had recurred in significantly (p=0.04) more animals that did not receive the commercial feed initially (3/5; 60%; mean [range] ESGD grade 3 [0,4]) compared to those that did (0/5; 0%; mean [range] ESGD grade 0 [0,0]). Thus, the commercial beet pulp/alfalfa/oat fibre mix aided prevention of ESGD recurrence when fed during the healing and prevention phases.

Abstract
Metastatic gastrointestinal cancer is not an uncommon situation, especially for pancreatic, gastric, and colorectal cancers. In this setting, few data are available on the impact of the treatment of the primary tumour. Oligometastatic disease is associated with longer survival in comparison with more advanced disease. Metastasis-directed therapy, such as stereotactic body radiotherapy, seems related to better outcomes, but the level of evidence is low. In most tumour locations, prospective data are very scarce and inclusion in ongoing trials is strongly recommended.

Abstract
INTRODUCTION AND IMPORTANCE Gastric volvulus is an abnormal rotation of all or part of the stomach around one of its axes. It is a rare clinical entity and a potentially life-threatening condition. Mesenteroaxial volvulus is a less commonly encountered variant of gastric volvulus. The objective of this study was to describe a rare case of Mesenteroaxial volvulus in a 12-year-old female child. CASE PRESENTATION A 12-year-old female child presented with a complaint of severe abdominal pain of two days duration associated with abdominal distention, failure to pass faeces and flatus, difficulty of breathing, and bloating. The vital sign was blood pressure of 90/60 mmHg, pulse rate of 130 beats per minute, respiratory rate of 29 breaths per minute, and temperature 37.8 degree Celsius. On abdominal examination, there was distension, hyperactive bowel sound, tenderness, and splenomegaly. Exploratory laparotomy was done and the intraoperative finding was gastric volvulus with Mesentroaxial type which was slightly ischemic with poor ligamentous attachment. Decompression with a Nasogastric tube (NGT) and gastropexy was done. The child was discharged on the 6th postoperative day. CLINICAL DISCUSSION Gastric volvulus is an abnormal rotation of the stomach on horizontal or vertical axes causing various degrees of obstruction. Mesenteroaxial volvulus is most commonly seen in young children and is associated with ligamentous laxity. CONCLUSION Gastric volvulus causes grave complications and death if not recognized early or surgical intervention is taken timely. Though it is a rare clinical entity, the primary physician should be aware of the clinical presentation.

Abstract
BACKGROUND Inflammatory myofibroblastic tumor (IMT) is a unique, rarely metastatic tumor composed of myofibroblasts and fibrous spindle cells with inflammatory cell infiltration that can affect any organ in the human body. By reviewing the relevant literature on PubMed, we found that this is the first case report of IMT with both gastric and cardiac involvement. CASE PRESENTATION A 57-year-old male patient was admitted to the hospital with complaints of malaise, poor appetite, and epigastric pain with black stools. We found a mass in the patient's stomach and left atrium by contrast-enhanced computed tomography, 18 F-fluorodeoxyglucose positron emission tomography/computed tomography, and other tests. The patient underwent laparoscopic Billroth II subtotal gastrectomy and Braun's gastrointestinal reconstruction under general anesthesia. On the 46th day following stomach surgery, the cardiac tumor was removed under general anesthesia. The patient has treated with doxorubicin 70 mg of D1 chemotherapy two months after cardiac surgery. Postoperative pathological immunohistochemistry of the mass confirmed the diagnosis of an IMT. His review three months after the cardiac surgery suggested the progression of the left atrial mass, but he declined further treatment and finally died one month after the review. CONCLUSIONS As a unique class of tumors that rarely metastasize, IMTs have an unknown etiology and pathogenesis, and distant metastasis is primarily observed in patients with negative activin receptor-like kinase (ALK) expression. The preferred treatment for IMT is complete surgical resection, and the effectiveness of adjuvant therapy for patients with distant metastases is still being determined. The clinical presentation of IMT lacks specificity and is often related to the location of tumor growth, which poses a diagnostic challenge. Pathological immunohistochemistry is the only way to confirm the diagnosis at present. Our case report reminds clinicians that a category of ALK-negative IMT with a tendency toward distant metastasis should not be ignored.

Abstract
OBJECTIVE Gastrointestinal metaplasia (GIM) has a close relationship with gastric cancer (GC), but it is unclear how to judge which GIM could develop into GC. This study aimed to assess the role of CDX2 and its association with Helicobacter pylori (H.pylori) genotypes in GIM. METHODS CagA and vacA genes were identified via PCR in 466 H. pylori-positive gastric tissues, including gastritis (n=104), GIM diagnosed endoscopically (GIM-1; n=82), gastric cancer (GC; n=173), and paired adjacent GIM tumors resected surgically (GIM-2; n=107). GIM was subclassified per the HID- AB pH2.5-PAS as follows: type I (n=23), type II (n=43), and type III (n=16) in GIM-1; type I (n=8), type II (n=40), and type III (n=59) in GIM-2. CDX2 expression was evaluated immunohistochemically. RESULTS In GIM-1, the infection rate of vacAm2 (55.8%) and vacAs1m2 (53.5%) was higher in subtype II than in others (P<0.05), while that of vacAm1 (49.2%) and vacAs1m1 (33.9%) was higher in subtype III than in others. The cagA+ rate was higher in subtypes I (75.0%) and III (64.4%) than in subtype II (40.0%; P<0.05) respectively. CDX2 was upregulated in subtype I than in subtypes II and III in GIM-1 and GIM-2. In GIM-2 and GC, CDX2 was downregulated in vacAm1, vacAs1m1, and cagA+ (P<0.05). The predominant genotype was vacAs1m2 in subtype II of GIM-1, CDX2 expression remaining unaltered; however, the predominant genotype was cagA+ vacAs1m1 in subtypes II and III of GIM-2, negatively correlated with CDX2 expression. CONCLUSION These GIM subtypes (cagA+ vacAs1m1 H. pylori-positive GIM with negative CDX2 expression) resemble GC and should be evaluated similar to cancerous GIM.

Abstract
Background: Gastric cancer is an invasive cancer, which is usually diagnosed in advanced stages. However, the markers affecting its progression, and invasion are of great importance in its diagnosis and treatment. The current research aimed to study the correlation of genes that contributed to epithelial-mesenchymal transition (EMT), Mest1, and GjA1, with some clinicopathological specifications in gastric cancer patients to better comprehend the functions of these genes in this tumor. Materials and Methods: RNA was extracted from the tumor, and normal tissues and cDNA were synthesized. Then, by designing specific primers for Gja1 and Mest1 genes, their expressions were studied by RT-PCR. The data was analyzed by GraphPad Prism 8 software. Results: Significant differences among the expressions of mentioned genes associated with clinicopathological variables of gastric cancer patients, including tumor size, grade, stage, metastasis, and lymphatic invasion were seen. Conclusion: The obtained data showed the important role of EMT-related genes, Gja1 and Mest1 in the clinical progression of the tumor. Further studies with larger sample sizes are required to confirm these genes as biomarker candidates for detecting gastric cancer.

Abstract
There is a growing interest in the development of in vitro models that mimic the intrinsic characteristics of cells in vivo to replace and/or reduce the use of experimental animals. The stomach is lined with mucus secreting epithelial cells, creating a thick mucus layer that protects the underlying epithelial cells from acid, pathogens, and other harmful agents. Mucins are a main component of the mucus layer, and their secretion is an important protective feature of epithelial cells in vivo. Here, we present a method that differentiates pig gastric primary cells into mucin secreting epithelial cells by culturing the cells on polyester membranes under semi-wet interface for 14 days, using differentiation medium containing the N-[(3,5-difluorophenyl)acetyl]-L-alanyl-2-phenyl]glycine-1,1-dimethylethyl ester (DAPT) in the basolateral compartment for the first 7 days and subsequent 7-day culture in non-differentiation medium. The in vitro mucosal surfaces created by these cells are harvested 2 weeks post confluence, and two preservation methods are described to fix the monolayers for further analysis.

Abstract
Background and Objective Gastric cancer is the fifth most common cancer worldwide and the fourth leading cause of cancer-related death. Unfortunately, patients often present with advanced disease at diagnosis, which is directly related to its high mortality. Numerous trials, as early as the 1980's, have shown that cytotoxic chemotherapy improves survival. This review will focus on targeted therapies and immunotherapies which have emerged as treatment options for metastatic gastric cancer, often used in conjunction with cytotoxic chemotherapy. Here we will review the relevant clinical trials of targeted therapies and immunotherapies in the treatment of metastatic gastric cancer. Methods We performed an extensive review of articles in the PubMed database pertaining to targeted therapies and immunotherapies in the treatment of metastatic gastric cancer. Additionally, updated guidelines from the National Comprehensive Cancer Network (NCCN) and European Society for Medical Oncology (ESMO) were reviewed. Key Content and Findings Cytotoxic chemotherapy remains the backbone of treatment of metastatic gastric cancer, but the development of targeted therapies and immunotherapy have revolutionized its treatment with improved survival and outcomes. Therapies have been developed which target human epidermal growth factor receptor 2 (HER2), vascular endothelial growth factor receptor-2 (VEGFR-2), and tyrosine kinase pathways. Novel targeted therapies are currently being investigated with promising results thus far. Immunotherapy, specifically immune checkpoint inhibitors (ICIs), has proven to be a significant advancement in the treatment of gastric cancer. Conclusions Targeted therapies and immunotherapies have improved survival and outcomes in metastatic gastric cancer, however more research is needed to make even greater strides.

Abstract
Current treatments for stomach cancer are often effective in curing cancer. However, these treatments can also have significant side effects, and they may not be effective in all cases. Hence synthetic compounds exhibit promise as potential agents for cancer treatment. In a previous study, we identified (E)-N'- (2,3,4-trihydroxybenzylidene) isonicotinohydrazide (ITHB4) as a novel antimycobacterial derivative of isoniazid with cytotoxic effects on the MCF-7 breast cancer cell line. This led us to investigate the potential anti-cancer properties of ITHB4 against adenocarcinoma gastric (AGS) cell line. The cytotoxic effect of ITHB4 has been determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay and further confirmed for anticancer properties by means of apoptosis, reactive oxygen species (ROS), nuclear fragmentation, lactate dehydrogenase (LDH), caspases, cytokines and morphological including phenotypic changes of cells assay. The ITHB4 demonstrated a lower IC50 in inhibiting growth of AGS cells at 24 h compared to 48 and 72 h. ITHB4 has also shown no toxicity human immune cells. Treatment of ITHB4 against AGS for 24 h eventually lead to formation of early apoptotic AGS cells, reduced mitochondrial membrane potential, nuclear condensation, and nuclear fragmentation lastly increased in ROS levels together with the release of LDH, and secretion of caspases. The altered cytokine profile in ITHB4 treated AGS hints at the possibility that ITHB4 may possess anti-tumor and anti-inflammatory properties. Our results in this study demonstrate that ITHB4 has almost similar chemotherapeutic properties against gastric adenocarcinoma cells compared to breast cancer cell. This is suggesting that the anticancer capabilities of this compound should be in vivo and clinically assessed.

Abstract
PURPOSE We recently showed that low microsatellite instability (MSI-L) is associated with a good response to platinum/5-fluorouracil (5-FU) neoadjuvant chemotherapy (CTx) in gastric cancer. The purpose of this study was to characterize the instability pattern and to investigate an association of MSI-L tumors with mutations in genes of DNA repair pathways and with total tumor mutation burden (TMB). METHODS MSI patterns were compared between 67 MSI high (-H) and 35 MSI-L tumors. Whole-exome sequencing was performed in 34 microsatellite stable (MSS) and 20 MSI-L tumors after or without neoadjuvant CTx. RESULTS Of the 35 MSI-L tumors, 33 tumors had instability at a dinucleotide repeat marker. In the homologous recombination (HR) pathway, 10 of the 34 (29%) MSS and 10 of the 20 (50%) MSI-L tumors showed variants (p = 0.154). In the DNA damage tolerance pathway, 6 of the 34 (18%) MSS and 7 of the 20 (35%) MSI-L tumors had variants (p = 0.194). The HR deficiency score was similar in both tumor groups. TMB was significantly higher in MSI-L compared to MSS tumors after CTx (p = 0.046). In the MSS and MSI-L tumors without CTx no difference was observed (p = 1.00). CONCLUSION MSI-L due to instability at dinucleotide repeat markers was associated with increased TMB after neoadjuvant CTx treatment, indicating sensitivity to platinum/5-FU CTx. If confirmed in further studies, this could contribute to refined chemotherapeutic options including immune-based strategies for GC patients with MSI-L tumors.

Abstract
BACKGROUND The inflammatory myofibroblastic tumor (IMT) is a rare mesenquimal tumor of doubtful biological behaviour. It's characterised for affecting mainly children and young adults, although it can appear at any age, being the lungs the primary affected organ (in children it represents 20% of all primary pulmonary tumors). CASE SUMMARY We present the case of a 45 year old woman, with a computed tomography (CT) finding of injury on the anterior surface of the fundus/gastric body and a solid perigastric injury of 12 mm in the ecoendoscopy. The case is presented in the tumor committee deciding to perform a laparoscopic wedge resection. The histological diagnosis was a IMT. The diagnosis is based on imaging tests like the abdominal CT, abdominal ecography and the ecoendoscopy but to confirm the diagnosis a pathological study is necessary. CONCLUSION Due to the unpredictable nature of this tumor, surgical resection is the best therapeutic option.

Artificial intelligence (AI) has achieved remarkable development in this field. This study aimed to develop an AI-based EUS diagnostic model for the diagnosis of SELs, and evaluated its efficacy with external validation. Methods We developed the EUS-AI model with ResNeSt50 using EUS images from two hospitals to predict the histopathology of the gastric SELs originating from muscularis propria. The diagnostic performance of the model was also validated using EUS images obtained from four other hospitals. Results A total of 2,057 images from 367 patients (375 SELs) were chosen to build the models, and 914 images from 106 patients (108 SELs) were chosen for external validation. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the model for differentiating gastrointestinal stromal tumors (GISTs) and non-GISTs in the external validation sets by images were 82.01%, 68.22%, 86.77%, 59.86%, and 78.12%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in the external validation set by tumors were 83.75%, 71.43%, 89.33%, 60.61%, and 80.56%, respectively. The EUS-AI model showed better performance (especially specificity) than some endosonographers. The model helped improve the sensitivity, specificity, and accuracy of certain endosonographers. Conclusions We developed an EUS-AI model to classify gastric SELs originating from muscularis propria into GISTs and non-GISTs with good accuracy. The model may help improve the diagnostic performance of endosonographers. Further work is required to develop a multi-modal EUS-AI system.

Abstract
BACKGROUND Obesity has been positively associated with gastric cancer. Excess fat impacts hormones, which have been implicated in carcinogenesis. We investigated obesity-related hormones and cardia gastric cancer (CGC) and non-cardia gastric cancer (NCGC) risk. METHODS Nested case-control studies were conducted within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort (61 CGCs, and 172 NCGCs and matched controls) and the Alpha-Tocopherol, Beta-Carotene Cancer Prevention (ATBC) study (100 CGCs and 65 NCGCs and matched controls); serum hormones were measured. In UK-Biobank (n = 458,713), we included 137 CGCs and 92 NCGCs. Sex-specific analyses were conducted. For EPIC and ATBC, odds ratios (ORs), and for UK-Biobank hazard ratios (HRs), were estimated using conditional logistic regression and Cox regression, respectively. RESULTS Insulin-like growth-factor-1 was positively associated with CGC and NCGC in EPIC men (ORper 1-SD increase 1.94, 95% CI 1.03-3.63; ORper 1-SD increase 1.63, 95% CI 1.05-2.53, respectively), with similar findings for CGC in UK-Biobank women (HRper 1-SD increase 1.76, 95% CI 1.08-2.88). Leptin in EPIC men and C-peptide in EPIC women were positively associated with NCGC (ORT3 vs. T1 2.72, 95% CI 1.01-7.34 and ORper 1-SD increase 2.17, 95% CI 1.19-3.97, respectively). Sex hormone-binding globulin was positively associated with CGC in UK-Biobank men (HRper 1-SD increase 1.29, 95% CI 1.02-1.64). Conversely, ghrelin was inversely associated with NCGC among EPIC and ATBC men (ORper 1-SD increase 0.53, 95% CI 0.34-0.84; ORper 1-SD increase 0.22, 95% CI 0.10-0.50, respectively). In addition, dehydroepiandrosterone was inversely associated with CGC in EPIC and ATBC men combined. CONCLUSIONS Some obesity-related hormones influence CGC and NCGC risk.

Abstract
BACKGROUND Ectopic pancreas may be unfamiliar to many people because it is rare and difficult to diagnose. However, this disease is highly susceptible to misdiagnosis and missed diagnosis. In this article, we report two cases of pancreatic heterotopia in the gastric sinus and small intestine, respectively, both of which were confirmed by histopathological examination. CASE SUMMARY The first patient was a 43-year-old female which reported abdominal distension for 2 mo. The second was a 67-year-old female who experienced intermittent epigastric discomfort for 15 d. In both cases, there was no confirmed preoperative examination, and the postoperative pathology indicated the presence of ectopic pancreas. CONCLUSION The diagnosis of ectopic pancreas is difficult, and is often prone to misdiagnosis and the possibility of being overlooked. Various laboratory tests and imaging tests should be carefully evaluated before surgery to achieve early detection, early diagnosis and early treatment.

Abstract
BACKGROUNDS Extended resection for gastric cancer in elderly patients is still challenging for surgeons. This study aimed to evaluate the prognosis and the postoperative outcomes of elderly patients underwent gastric cancer surgery in a high-volume center. METHODS The medical records of patients with gastric cancer surgery at Marmara University Hospital's General Surgery Department were examined retrospectively. Patients were divided into two groups: Age ≤ 70 and Age > 70. The clinicopathological data of the patients were compared. The prognostic factors regarding gastric cancer surgery were analyzed with Cox proportional regression models. Kaplan Meier analysis and log-rank test were used to compare Overall Survival (OS) and Cancer-Specific Survival (CSS) among the groups. Competing risk regression analysis was used to examine cause-specific hazards among elderly patients. RESULTS The number of eligible patients was 250. Age > 70 group was 68 patients, and Age ≤ 70 group was 182 patients. There is no significant difference between the patient's demographics or pathological outcomes. Neoadjuvant therapies performed less in elderly patients [40 (22%) vs. 7 (10%), p: 0.03, respectively]. There was no significant difference in severe complication (≥ Grade III) rates in both groups. Multivariate analysis showed that advanced T stage and adjacent organ invasion were the independent risk factors for OS. No significant difference was observed between the groups regarding OS (Log Rank (Mantel-Cox): 0.102). Younger patients have worse CSS than those who are older. Cause-specific hazard model demonstrated a not increased hazard ratio [HR: 1.04(0.78-1.38)] for elderly patients for OS and CSS. CONCLUSION Gastric resections can be safely performed for elderly patients diagnosed with gastric cancer. This study showed that growing age is no longer a factor that will affect the clinician's decision in performing surgery in gastric cancer patients.

Abstract
BACKGROUND The molecular changes present in gastric neuroendocrine tumors (NETs) include a loss of heterozygosity or mutation of MEN1, CDKN1B gene mutation, P27 heterozygous mutation, and ATP4A gene missense mutation. We identified and are the first to report a case of type 1 histamine-producing enterochromaffin-like cell NETs (ECL-cell NETs) with a BRCA2 gene germline mutation. CASE SUMMARY The patient had a history of iron-deficient anemia for 5 years, and gastroscopic examination indicated multiple gastric tumors. Then, the patient underwent distal gastrectomy. Microscopically, multifocal tumor cells were found in the mucosa and submucosa; tumor cells were organoid and arranged in nests and cords, and the stroma was rich in sinusoids. The surrounding gastric mucosa showed atrophy with mild intestinal metaplasia or pseudopyloric gland metaplasia. Neuroendocrine cells could be seen with diffuse linear, nodular, and adenomatous hyperplasia. Immunohistochemically, the tumor cells diffusely expressed cytokeratin, chromogranin, synaptophysin, and CD56. Whole-genome high-throughput molecular sequencing revealed a pathogenic germline mutation in the BRCA2 gene, a heterozygous germline frameshift mutation in exon 11, c.6443_6444del (p.S2148Yfs*2). The final diagnosis was gastric type 1 ECL-cell NETs with a BRCA2 gene germline mutation, accompanied by autoimmune gastritis. CONCLUSION This is the first report of a case of type 1 gastric ECL-cell NETs with a pathogenic germline mutation of the BRCA2 gene. The findings of this report will expand the germline mutation spectrum of gastric NETs and increase the understanding of the molecular changes present in these tumors for their improved diagnosis in the future.

Abstract
INTRODUCTION At a national level, understanding preventable mortality after oesophago-gastric cancer surgery can direct quality-improvement efforts. Accordingly, utilizing the Australian and New Zealand Audit of Surgical Mortality (ANZASM), we aimed to: (1) determine the causes of death following oesophago-gastric cancer resections in Australia, (2) quantify the proportion of potentially preventable deaths, and (3) identify clinical management issues contributing to preventable mortality. METHODS All in-hospital mortalities following oesophago-gastric cancer surgery from 1 January 2010 to 31 December 2020 were analysed using ANZASM data. Potentially preventable and non-preventable cases were compared. Thematic analysis with a data-driven approach was used to classify clinical management issues. RESULTS Overall, 636 complications and 123 clinical management issues were identified in 105 mortalities. The most common causes of death were cardio-respiratory in aetiology. Forty-nine (46.7%) deaths were potentially preventable. These cases were characterized by higher rates of sepsis (59.2% vs 33.9%, p = 0.011), multiorgan dysfunction syndrome (40.8% vs 25.0%, p = 0.042), re-operation (63.3% vs 41.1%, p = 0.031) and other complications compared with non-preventable mortality. Potentially preventable mortalities also had more clinical management issues per patient [median (IQR): 2 (1-3) vs 0 (0-1), p < 0.001), which adversely impacted preoperative (30.6% vs 7.1%, p = 0.002), intraoperative (18.4% vs 5.4%, p = 0.037) and postoperative (51.0% vs 17.9%, p < 0.001) care. Thematic analysis highlighted recurrent areas of deficiency with preoperative, intraoperative and postoperative patient management. CONCLUSIONS Almost 50% of deaths following oesophago-gastric cancer resections were potentially preventable. These were characterized by higher complication rates and clinical management issues. We highlight recurrent themes in patient management to improve future quality of care.

Abstract
PURPOSE To investigate the prognostic role of microsatellite instability (MSI) in association with sex of patients treated with platinum/fluoropyrimidine neoadjuvant chemotherapy (CTx) with or without a taxane-containing compound. METHODS Of the 505 retrospectively analyzed patients with gastric or gastroesophageal adenocarcinoma, 411 patients were treated without taxane and 94 patients with a taxane-containing compound. MSI was determined using standard assays. RESULTS Females demonstrated a better overall survival (OS) than males in the non-taxane group (HR, 0.59; 95% CI 0.41-0.86; p = 0.005), whereas no significant difference was found in the taxane group (HR 1.22; 95% CI 0.55-2.73, p = 0.630). MSI-High (-H) was associated with a better prognosis in both groups (without taxane: HR 0.56; 95% CI 0.33-0.97; p = 0.038; with taxane: HR 0.28; 95% CI 0.04-2.02, p = 0.204). In the non-taxane group, female MSI-H patients showed the best OS (HR 0.18, 95% CI 0.05-0.73; p = 0.016), followed by the female microsatellite stable (MSS) (HR 0.67, 95% CI 0.46-0.98, p = 0.040) and the male MSI-H group (HR 0.76; 95% CI 0.42-1.37, p = 0.760) taken the male MSS group as reference. In the taxane group, female and male MSI-H patients demonstrated the best OS (female MSI-H: HR 0.05, 95% CI 0.00-240.46; male MSI-H: HR 0.45, 95% CI 0.61-3.63, p = 0.438), whereas the female MSS group showed a decreased OS (HR 1.39 95% CI 0.62-3.12, p = 0.420) compared to male MSS patients. CONCLUSION OS in gastric/gastroesophageal cancer after CTx might depend on sex and MSI status and may differ between patients treated with or without a taxane compound in the chemotherapeutic regimen.

Abstract
BACKGROUND To explore the hematological toxicity (HT) induced by neoadjuvant chemoradiotherapy (nCRT) compared with neoadjuvant chemotherapy (nCT) and to identify the appropriate vertebral body (VB) dosimetric parameters for predicting HT in patients with locally advanced gastric cancer (GC). METHODS In the phase III study, 302 patients with GC from an ongoing multi-center randomized clinical trial (NCT01815853) were included. Patients from two major centers were grouped into training and external validation cohorts. The nCT group received three cycles of XELOX chemotherapy, while the nCRT received the same dose-reduced chemotherapy plus 45 Gy radiotherapy. The complete blood counts at baseline, during neoadjuvant treatment, and in the preoperative period were compared between the nCT and nCRT groups. The VB was retrospectively contoured and the dose-volume parameters were extracted in the nCRT group. Patients' clinical characteristics, VB dosimetric parameters, and HTs were statistically analyzed. Instances of HT were graded according to the Common Terminology Criteria for Adverse Events v5.0 (CTCAE v5.0). The receiver operating characteristic (ROC) curves were generated to identify the optimal cut-off points for dosimetric variables and verify the prediction efficiency of the dosimetric index in both training and external validation cohorts. RESULTS In the training cohort, 27.4% Grade 3 + HTs were noted in the nCRT group and 16.2% in the nCT group (P = 0.042). A similar result was exhibited in the validation cohort, with 35.0% Grade 3 + HTs in the nCRT group and 13.2% in the nCT group (P = 0.025). The multivariate analysis of the training cohort revealed that V5 was associated with Grade 3 + leukopenia (P = 0.000), Grade 3 + thrombocytopenia (P = 0.001), and Grade 3 + total HTs (P = 0.042). The Spearman correlation analysis identified a significant correlation of V5 with the white blood cell nadir (P = 0.0001) and platelet nadir (P = 0.0002). The ROC curve identified the optimal cut-off points for V5 and showed that V5 < 88.75% could indicate a decreased risk of Grade 3 + leukopenia, thrombocytopenia, and total HTs in the training as well as the external validation cohorts. CONCLUSIONS Compared with nCT, nCRT could increase the risk of Grade 3 + HT in patients with locally advanced GC. Dose constraints of V5 < 88.75% in irradiated VB could reduce the incidence of Grade 3 + HT.

Abstract
BACKGROUND Multidisciplinary tumor board (MDT) discussion is standard practice in the management of Upper Gastrointestinal (UGI) cancers. However, poor adherence to MDT recommendations may account for the lack of improved oncological outcomes with MDTs. We aim to quantify adherence rates and compare outcomes between adherent and non-adherent patients. METHODS We included all patients with potentially curable primary UGI carcinomas who were discussed at UGI MDT from 2017 to 2018. MDT recommendations were compared to actual treatment received. Oncological and survival outcomes were compared between both groups. RESULTS Amongst 153 patients, 64 (41.8%) were non-adherent to MDT recommendations. Reasons for non-adherence were patient refusal (50.0%), treatment-related complications (31.3%), disease factors (17.2%) and clinician decision (1.56%). Univariate analysis showed that non-adherent patients were older (71.6 vs 65.2 years, p < 0.001), with higher clinical stage at point of diagnosis (p = 0.028), pathological stage after resection (p < 0.001) and were more likely to be recommended for multimodal therapy. No significant factors were associated with non-adherence at multivariate analysis. Non-adherent patients had worse median overall survival (19.5 months) compared to adherent patients (not reached at follow-up) with both unmatched and propensity-score matched analysis. Patients who received only part of the intended adjuvant chemotherapy course had worse median overall survival and disease-free survival compared to patients who completed or did not initiate adjuvant chemotherapy. CONCLUSIONS Non-adherence to MDT recommendations was associated with advanced age and tumor stage, and potentially contributes to the worse oncological outcomes in a group of patients already predisposed to poor outcomes.

Abstract
Background: Household food insecurity (HFI) which has still been one of the major global public health issues is related to adverse health outcomes in individuals. Therefore, this study aimed to determine the prevalence of HFI and its associated factors in Iranian patients with esophageal and gastric cancers. Methods: The data of this cross-sectional study was obtained from 315 patients with esophageal and gastric cancers who were selected from a gastrointestinal cancer-based cohort study conducted in Firoozgar hospital, in Tehran. Food insecurity (FI) was measured using the Iranian version of the HFI questionnaire that was completed by a trained interviewer. The multivariable logistic regression model was used to determine the independent association of each factor with HFI. A P value lower than 0.05 was considered statistically significant. Results: The mean±SD of participants' age was 63.2±12.6 years and 65.4% were men. Most of the patients (75.8%) suffered from gastric cancer and 24.2% from esophageal cancer. The overall prevalence of FI among participants' households was 35.2%. There was an independent significant association between wealth index (WI) and HFI after the use of the multivariable logistic regression model, in such a way that the odds of FI in the poorest, poor, moderate, and rich patients' households were respectively, 6.41, 5.05, 2.74 and 2.04 times higher compared with the richest households. Conclusion: More than a third of participants' households struggled with FI, which was found to have a higher prevalence in loweconomic households. Therefore, health policymakers should intervene in food-insecure households by developing, establishing, and implementing strategies and control programs to improve affordable food access.

Abstract
Objective Primary gastric lymphomas, which make up the vast majority of extranodal non-Hodgkin lymphoma, are rare and the most common subtype is primary gastric diffuse large B-cell lymphoma (PG-DLBCL). In our study, we investigated the clinical and prognostic factors of this lymphoma type as a single-center experience. Materials and Methods Between January 2001 and February 2021, 91 patients aged ≥18 years, registered with the diagnosis of primary gastric DLBCL, diagnosed histopathologically, and whose evaluation parameters were reached, were retrospectively scanned. Results The median age of 91 patients with a diagnosis of PG-DLBCL was 58 (20-81, minimum-maximum) years. Of the patients, 64.8% were men and 35.2% were women. While the number of patients with an International Prognostic Index (IPI) score of 0-2 (low-low-intermediate risk) was 54 (59.4%), the number of patients with an IPI score of 3 (high intermediate) was 19 (20.9%), and the number of patients with an IPI score of 4-5 (high risk) was 18 (19.8%). While 52.7% of the patients had a complete response, 20.9% had a partial response, 3.3% had stable disease, and 23.1% had progressive disease. The 10-year event-free survival (EFS) and overall survival (OS) rates for all patients, respectively, were 52.1% and 53.2%. We found factors affecting survival in univariate analysis; age groups (≤60/>60), ECOG groups (0-1/≥2), Lugano stage (I-II/III-IV), LDH level (normal/high), IPI risk groups (low/low-intermediate/high-intermediate/high) and radiotherapy (yes/no). In multivariate analysis, only; age groups (≤60/>60) and IPI risk groups (low/low-intermediate/high-intermediate/high) were found to be independent factors affecting survival. In addition, in our study, we determined that the division of the IPI intermediate risk group into low intermediate and high intermediate is one of the factors predicting prognosis. Conclusions Few studies of PG-DLBCL have investigated the long-term survival rates of patients and primarily examined small patient groups because of the low incidence of the disease. In our study, we think that detailed evaluation of age and especially IPI risk groups play a role in predicting survival.

Abstract
General surgical procedures on the gastrointestinal tract are commonly performed worldwide. Surgical resections of the stomach, small intestine, or large intestine can have a significant impact on the anatomy and physiological environment of the gastrointestinal tract. These physiological changes can affect the effectiveness of orally administered formulations and drug absorption and, therefore, should be considered in rational drug formulation design for specific pathological conditions that are commonly associated with surgical intervention. For optimal drug delivery, it is important to understand how different surgical procedures affect the short-term and long-term functionality of the gastrointestinal tract. The significance of the surgical intervention is dependent on factors such as the specific region of resection, the degree of the resection, the adaptive and absorptive capacity of the remaining tissue, and the nature of the underlying disease. This review will focus on the common pathological conditions affecting the gastric and bowel regions that may require surgical intervention and the physiological impact of the surgery on gastrointestinal drug delivery. The pharmaceutical considerations for conventional and novel oral drug delivery approaches that may be impacted by general surgical procedures of the gastrointestinal tract will also be addressed.

Abstract
BACKGROUND The prevalence of sarcopenia in gastric cancer (GC), although varying among the reported studies, is around 60%. In the last few years, it has been recognised that sarcopenia can also occur not only in patients with weight loss and low body weight, but also in patients with normal or increased body mass index. Therefore, the term sarcopenic obesity (SO) is a new definition that further expands the implications of altered body composition. The aim of this study was to assess the impact of SO on the perioperative morbidity and the survival of GC patients undergoing gastrectomy by evaluating body composition on CT images. METHODS Preoperative CT scans were obtained from all patients with a diagnosis of GC undergoing gastrectomy with curative intent between January 2012 and December 2019. Skeletal muscle mass index (SMMI) and visceral adipose tissue (VAT) cross-sectional area at the level of the transverse processes of the third lumbar vertebra (L3) were measured. Sarcopenia and obesity were defined according to sex-specific cut-off points. RESULTS After analysing 190 patients, the prevalence of SO was 21.1% (40 patients) and sarcopenia was 14.7% (28 patients). Multivariate analysis showed that corporal composition was an independent factor of overall survival (p = 0.049). Logistic regression was performed to identify risk factors associated with postoperative complications. SO was identified as a risk factor for serious Clavien-Dindo complications > IIIb/IV [OR 2.82 (1.1-7.1); p = 0.028]. CONCLUSION SO was a risk factor for severe postoperative complications as well as worse long-term oncological after a gastrectomy for GC.

Abstract
The latest WHO classification of the female genital tract tumors introduces a new type of carcinoma: the primary gastric-type (or gastro-intestinal type) carcinoma of the endometrium. This type of neoplasm tends to have a poor outcome, making its correct diagnostic important. As little is known about this entity and given its quite challenging diagnosis, we aim to review existing data about it and propose a practical diagnostic approach. There are currently 11 cases published in 8 articles fitting the precise definition of a primary gastric-type carcinoma of the endometrium. Three main differential diagnoses must be excluded before considering this tumor: endometrioid adenocarcinoma with mucinous (Müllerian-type) differentiation, endocervical primary, and gastro-intestinal primary. Morphological aspects of this tumor can be heterogeneous and confusing; in this context, immunochemistry can be helpful to highlight the gastric or intestinal differentiation, but also to eliminate a mucinous endometrioid adenocarcinoma of Müllerian-type, by the constant negativity of estrogen receptors. A metastasis of a primary gastro-intestinal tract carcinoma must also be excluded by clinical, endoscopic and imaging work-up. Finally, an endometrial extension of a primary endocervical gastric-type carcinoma should be ruled out by complete sampling of the cervix. Intestinal type endocervical adenocarcinoma is easier to eliminate since this is an HPV-associated neoplasm.

Abstract
BACKGROUND Ample evidence supports the potential of programmed death-ligand 1 (PD-L1) expression, detected by immunohistochemistry, as a predictive biomarker for immunotherapy in patients with advanced cancers. To predict the response to immune checkpoint inhibitors in patients with gastric and urothelial carcinomas, we aimed to replace PD-L1 combined positive score (CPS) with CD274 mRNA in the original four-gene signature and PD-L1 CPS model developed by us. METHOD We used quantitative real-time polymerase chain reaction (qRT-PCR) to measure the expression levels of five target genes in a cohort of 49 patients (33 with gastric cancer and 16 with urothelial carcinoma) who had received immunotherapy and whose therapeutic responses were available. The predictive performance was evaluated using R package maxstat. RESULTS Cutoff values of mRNA expression level were measured using the log-rank statistics for progression-free survival (PFS). Based on these cutoffs, immunotherapy responses were predicted and sorted into responder (n = 12, 24.5%) and non-responder (n = 37, 75.5%) groups. The median PFS values of predicted responders and non-responders were 14.8 months (95% confidence interval [CI]: 0-34.7) and 4.7 months (95% CI: 1.0-8.4, p = 0.02), respectively. Among the 12 predicted responders, 10 had microsatellite-stable tumors with a low tumor mutational burden. The actual clinical responses (complete and partial) were higher in the responder group than those in the non-responder group: 83.3% and 16.2%, respectively. CONCLUSION We modified a predictive biomarker for CD274 mRNA expression to predict the response to immunotherapy in patients with gastric or urothelial carcinomas.

Abstract
INTRODUCTION Gastric cancer is divided into four subtypes by their molecular features linked with genetic alterations, e.g., Epstein-Barr virus (EBV), microsatellite instability-high (MSI-high), chromosomal instability (CIN), and genomically stable (GS), called as TCGA classification. In this study, we tried to clarify the epigenetic features of the four GC subtypes according to aberrant methylation status in 23 loci. METHODS A total of 98 gastric cancers and their normal gastric mucosa samples were included in this study. We divided gastric cancers into TCGA subtypes which were determined in line with MSI-high, EBV, CIN, to GS by their molecular features. The 13 loci of polymorphic microsatellite sequences were used to determine loss of heterogeneity for the detection of CIN. The MSI status was determined by three mononucleotide repeat markers. Infection of EBV was determined by recovering EBV BNRF1 sequence from genomic DNA collected from gastric cancers. Methylation status of 23 loci was investigated by the combined bisulfite restriction analysis. Status of other findings, e.g., KRAS mutations, HER2 expression status, and infection of helicobacter pylori were confirmed. RESULTS Gastric cancers were divided into MSI (13%), EBV (7%), CIN (53%), and GS (27%). By histological classification, poorly differentiated adenocarcinoma was more in tumors categorized in MSI-high, and GS and signet-ring cell carcinoma (sig) were more in GS. Among the 23 loci investigated their methylation status, 18 loci were significantly hypermethylated in caner tissues. An unsupervised clustering divided gastric cancers into two clusters and revealed that most GS tumors clustered together in a cluster that exhibited lower methylation levels, distinct from the other subtypes. The inter-variable clustering revealed that a cluster contained the three loci (SFRP2-region 1/2 and APC) belonging to the Wnt signal cascade (Wnt-associated loci). The mean methylation score of Wnt-associated loci was the lowest in GS tumors (MSI-high: 2.7 [95% confidence interval, 2.3-2.9]; EBV: 2.1 [1.2-3.1]; CIN: 2.4 [2.2-2.7]; GS: 1.3 [0.8-0.7]). In contrast, the mean methylation score of the other 15 loci was significantly higher in MSI-high, while that in GS was as same as that in EBV or CIN (MSI-high: 10.4 [8.3-12.4]; EBV: 5.7 [1.7-9.7]; CIN: 4.4 [3.6-5.1]; GS: 3.4 [2.2-4.6]). Additionally, the lower methylation score of Wnt-associated loci was observed only in sig tumors. CONCLUSIONS GS subtype tumors have the potential to possess distinct signatures in DNA hypomethylation profiles in Wnt signaling pathway, especially in sig.

Abstract
Localized mesothelioma is a rare disease with very few reports of presentation in visceral organs. We report a case of localized gastric mesothelioma with lymph node metastasis in a 32-year-old man without asbestos exposure. A failed attempt at resection was made before presentation at another center. He was given perioperative chemotherapy that was followed by a D2 radical subtotal gastrectomy and hyperthermic intraperitoneal chemotherapy. Histopathology showed epithelioid mesothelioma with nodal metastasis but without visceral peritoneal involvement. Cytoreductive surgery and regional chemotherapy are standard in diffuse mesothelioma. Management of localized mesothelioma is anecdotal; however aggressive surgery plays a central role with selective use of perioperative chemotherapy.

Abstract
BACKGROUND Gastric mixed neuroendocrine-non-neuroendocrine neoplasm (MiNEN), which consists of neuroendocrine and non-neuroendocrine components, is quite rare. Until now, most data on gastric MiNEN come from clinical cases, without large-scale retrospective studies or controlled clinical trials. Consequently, no consensus regarding the origin, molecular characteristics, or appropriate treatment of MiNEN has been reached so far. We conducted chemotherapy of irinotecan plus cisplatin (IP regimen) and surgery in two patients with gastric MiNEN, which had never been used in treating this kind of tumor, leading to their long-term survival for more than 3 and 7 years, respectively.
CASE SUMMARY We present two patients (one male and one female) with gastric MiNEN, with the primary manifestation of recurrent upper abdominal pain. After they were referred to our hospital, a diagnosis of gastric MiNEN was defined with the help of CT scan, and histopathological and immunohistochemical examinations on the samples of gastrointestinal endoscopy or radical surgery. The male patient (case 1) were found to have metastases in the reginal lymph nodes and the left liver. He received four cycles of IP regimens first, then the gastrectomy and partial left liver resection, followed by additional two cycles of IP chemotherapy. The female patient (case 2) underwent a laparoscopic gastrectomy, and received six cycles of IP regimen. She was found to have metastatic lesions in the right lung 2 years after that, and underwent video-assisted thoracoscopic surgery (VATS) of the lower lobe of the right lung. The two patients have now survived for more than 3 years and 7 years, respectively, without any evidence of recurrence or metastases.
CONCLUSION IP regimen, combined with curative-intent surgery if feasible, could be considered as the priority in the choice of front-line chemotherapy for gastric MiNEN.

Abstract
One in four patients with colorectal cancer, 40% of gastric cancer patients, and 60% of ovarian cancer patients will develop peritoneal metastases (PM) in the course of their disease. The outcome of patients with widespread PM remains poor with currently available treatments. Despite the relatively common occurrence of PM, little is known on the pathophysiology that drives the peritoneal metastatic cascade. It is increasingly recognized that the stromal components of the peritoneal microenvironment play an essential role in tumor progression. However, little is known about the specific interactions and components of the peritoneal tumor microenvironment, particularly with respect the immune cell population. We summarize the current knowledge of the tumor immune microenvironment (TIME) in peritoneal metastases originating from the three most common origins: ovarian, gastric, and colorectal cancer. Clearly, the TIME is highly heterogeneous and its composition and functional activity differ according to tumor type and, within the same patient, according to anatomical location. The TIME in PM remains to be explored in detail, and further elucidation of their immune contexture may allow biology driven design of novel immune modulating or immune targeting therapies.

Abstract
Background The lesions of certain diseases are widely distributed in both stomach and small intestine, while the step-by-step strategy of gastroscopy followed by enteroscopy can be burdensome and costly. We aimed to determine if magnetically controlled capsule endoscopy (MCE) could be used in one-time gastro-small intestine (GSI) joint examination. Methods In this study, data of patients in Chinese PLA General Hospital and Changhai Hospital who underwent MCE GSI examination from January 2020 to August 2021 were retrospectively analysed. The primary outcome of this study was the success rate of one-time GSI joint examination, and secondary outcomes included visualization and cleanliness of gastrointestinal tract, gastrointestinal transit times, diagnostic yield and safety of MCE examination. Results A total of 768 patients were included. The success rate of one-time GSI joint examination was 92.58%. There were 94.92% MCEs observed > 90% gastric mucosa in the 6 anatomic landmarks. The rate of complete small bowel examination was 97.40%. The median gastric examination time, gastric transit time and small intestine transit time were 8.18 min, 63.89 min and 4.89 h, respectively. Magnetic steering of MCE significantly decreased gastric transit time (8.92 min vs. 79.68 min, P = 0.001) and increased duodenal lesion detection rate (13.47% vs. 6.26%, P = 0.001) when compared with non-magnetic steering group. Two capsules were retained and were removed by enteroscopy or spontaneously excreted. Conclusions MCE is feasible to complete GSI joint examination and the detection of both gastric and small intestinal diseases can be achieved simultaneously.

Abstract
INTRODUCTION Penetrating gastric injury (PGI) is common and although primary repair is sufficient for most injuries, several areas surrounding the peri-operative management remain contentious. This study reviews our experience in the management of PGI and review the clinical outcome at a major trauma centre in South Africa. MATERIALS AND METHODS A retrospective study was conducted from January 2012 to April 2020 at a major trauma centre in South Africa. RESULTS 210 cases were included (184 male, median age: 30 years). Mechanism of injury was 59% stab wounds (SWs) and 41% gunshot wounds (GSWs). The AAST grade was predominantly (92%) grade 2 for all cases. 20% (41/210) were isolated gastric injuries. All cases underwent primary repair and there were no cases of suture line failure. Eleven cases (5%) had one or more injuries not identified at the index laparotomy: 7 were unidentified gastric injuries and the remaining 4 were unidentified non gastric injuries. There was no association between unidentified injuries and mechanism of injury or outcome. Fifty-seven (27%) cases experienced one or more complications. Eighty-two cases (39%) required intensive care unit admission. The overall median length of hospital stay was 7 (IQR 4-11) days. The overall mortality was 14%. GSW injuries were more likely to have additional organ injury, higher ISS and PATI scores, longer length of hospitalization, higher likelihood of ICU stay, greater morbidity and mortality than SW injuries. There was a slight increase in the wound sepsis rate as number of associated extra gastric injuries increased but this was not statistically significant. There was no difference in wound overall sepsis rate between SW and GSW injuries (2% vs 8%, p=0.121). CONCLUSIONS Primary repair alone is sufficient for most PGI, but laparotomy is associated with high incidence of unidentified injury and surgeons must to be cognisant of the likelihood of these occult injuries.

Abstract
BACKGROUND & AIMS The management of gastrointestinal (GI) cancers is associated with high health care spending. We estimated trends in United States (US) health care spending for patients with GI cancers between 1996 and 2016 and developed projections to 2030. METHODS We used economic data, adjusted for inflation, developed by the Institute for Health Metrics and Evaluations for the Disease Expenditure Project. Corresponding US age-adjusted prevalence of GI cancers was estimated from the Global Burden of Diseases Study. Prevalence-adjusted temporal trends in the US health care spending in patients with GI cancers, stratified by cancer site, age, and setting of care, were estimated using joinpoint regression, expressed as annual percentage change (APC) with 95% confidence intervals (CIs). Autoregressive integrated moving average models were used to project spending to 2030. RESULTS In 2016, total spending for GI cancers was primarily attributable to colorectal ($10.50 billion; 95% CI, $9.35-$11.70 billion) and pancreatic cancer ($2.55 billion; 95% CI, $2.23-$2.82 billion), and primarily for inpatient care (64.5%). Despite increased total spending, more recent per-patient spending for pancreatic (APC 2008-2016, -1.4%; 95% CI, -2.2% to -0.7%), gallbladder/biliary tract (APC 2010-2016, -4.3%; 95% CI, -4.8% to -3.8%), and gastric cancer (APC 2011-2016, -4.4%; 95% CI, -5.8% to -2.9%) decreased. Increasing price and intensity of care provision was the largest driver of higher expenditures. By 2030, it is projected more than $21 billion annually will be spent on GI cancer management. CONCLUSIONS Total spending for GI cancers in the US is substantial and projected to increase. Expenditures are primarily driven by inpatient care for colorectal cancer, although per-capita spending trends differ by GI cancer type.

Abstract
This paper describes the feasibility of Attenuated total reflection-Fourier transform mid-infrared (ATR-MIR) spectroscopy method coupled with chemometrics for the rapid diagnostic approach and screening spectral changes for gastric and colon cancers from paraffin-embedded tissues. A total number of 82 tissue samples were analyzed by a simple ATR-MIR method combined with PCA, HCA, SIMCA and LDA methodologies. Spectral analyses showed significant differences for the molecular contents particularly about the lipid, nucleic acid, protein and other biomolecules in the samples of gastric cancer (GC) and colon cancer (CC) groups from their control/healthy groups. Significant changes in the characteristic of these molecules were only observed for cancer groups based upon the increment in their biosynthesis, and they could be utilized as diagnostic spectral biomarkers. Under the optimum conditions, SIMCA provided excellent classification for diseased and control groups, with 5% significance level. As well, 97.75% of the studied tissue samples were correctly discriminated on the basis of their origin by LDA. Consequently, the findings of this study highlighted the rapid diagnosis of gastric and colon cancer cases from paraffin-embedded tissues via ATR-MIR spectroscopy complemented with chemometrics.

Abstract
Disturbances in gastrointestinal (GI) microbiota could play a significant role in the development of GI cancers, but the underlying mechanisms remain largely unclear. While some bacteria seem to facilitate carcinogenesis, others appear to be protective. So far only one bacterium (Helicobacter pylori) has been classified by the International Agency for Cancer Research as carcinogenic in humans but many other are the subject of intense research. Most studies on the role of microbiota in GI tract oncogenesis focus on pancreatic and colorectal cancers with the following three species: Helicobacter pylori, Escherichia coli, and Porphyromonas gingivalis as likely causative factors. This review summarizes the role of bacteria in GI tract oncogenesis.

Abstract
Background/Aims Gastric cancers (GCs), particularly the Lauren intestinal type, show a male predominance. The aim of this study was to investigate the effects of reproductive factors on GCs in females, according to Lauren classification. Methods Medical records of 1,849 males and 424 females who underwent radical gastrectomy or endoscopic resection for GCs between 2010 and 2018 were reviewed. The incidences of intestinal-type GCs were compared between males and groups of females stratified according to postmenopausal period. Associations between reproductive factors in females and intestinaltype GCs were analyzed using multivariate models. Results The proportions of intestinal-type GCs were significantly lower in premenopausal (19%), less than 10 years postmenopausal (30.4%), and 10 to 19 years postmenopausal females (44.1%) than in males (61.0%) (p<0.05 for all). Females ≥20 years postmenopause had a proportion of intestinal-type GCs similar to that in males (60.6% vs 61.0%; p=0.948). Multivariate analysis revealed that age (odds ratio [OR], 1.075; 95% confidence interval [CI], 1.039 to 1.113; p<0.001) and parity ≥3 (OR, 1.775; 95% CI, 1.012 to 3.114; p=0.045) were positively associated with an increased risk of intestinal-type GCs in postmenopausal females, while long fertility duration (OR, 1.147; 95% CI, 1.043 to 1.261; p=0.005) was positively associated with an increased risk of intestinal-type GCs in premenopausal females. Conclusions There were no significant differences in the proportions of intestinal-type GCs between males and females ≥20 years postmenopause, suggesting that female reproductive factors play a role in the prevention of intestinal-type GC.

Abstract
Gastrointestinal (GI) cancers represent a heterogeneous group of malignancies, each with a unique tumor biology that in turn affects response to treatment and subsequent prognosis. The interplay between tumor cells and the local immune microenvironment also varies within each GI malignancy and can portend prognosis and response to therapy. Treatment with immune checkpoint inhibitors has changed the treatment landscape of various solid tumors including (but not limited to) renal cell carcinoma, melanoma, and lung cancer. Advances in the understanding between the interplay between the immune system and tumors cells have led to the integration of immunotherapy as standard of care in various GI malignancies. For example, immunotherapy is now a mainstay of treatment for tumors harboring defects in DNA mismatch repair proteins and tumors harboring a high mutational load, regardless of primary site of origin. Data from recent clinical trials have led to the integration of immunotherapy as standard of care for a subset of gastroesophageal cancers and hepatocellular carcinoma. Here, we outline the current landscape of immunotherapy in GI malignancies and highlight ongoing clinical trials that will likely help to further our understanding of how and when to integrate immunotherapy into the treatment of various GI malignancies.

Abstract
Lymphoepithelioma-like gastric carcinoma (LELGC) constitutes 1-4% of all gastric carcinomas and gastrointestinal involvement in leukemia can be present in up to 25%, being more common in acute than chronic leukemia, affecting most frequently the stomach, ileum, and proximal colon. LELGC is usually associated with a better prognosis than other gastric carcinomas, generally presenting with low T and N stages. The reports of chronic lymphocytic leukemia (CLL) involving infiltration of the gastrointestinal tract are relatively rare in the literature, and the estimated incidence ranges from 5.7% to 25%. We present the case of a 77-year-old female, on surveillance by a known CLL that was diagnosed with gastric carcinoma on an esophagogastroduodenoscopy (EGD) performed for epigastric pain. A subtotal gastrectomy was performed and the surgical specimen revealed simultaneous involvement of the stomach by LELGC and CLL. To the best of our knowledge, this is the first reported case of a LELGC and CLL simultaneously involving the stomach.

Abstract
Gastric type 1 neuroendocrine tumours are considered to have low rates of proliferation and a good prognosis. We report here a patient with an aggressive well-differentiated high-grade gastric neuroendocrine tumour (gastric grade 3 NET), in a context of autoimmune gastritis. Consistent with grade 3 disease, the tumour had a Ki-67 proliferation index of 30%. Targeted next-generation sequencing identified variants of four genes, including a pathogenic ATM variant underlying the differentiation and metastatic potential of the tumour. Liver metastasis was diagnosed during follow-up, and the patient died after 6 years, due to disease progression.
