ABSTRACT Background Aim Methods Results Conclusions While inflammation is implicated in the development of numerous cancers, whether eosinophilic oesophagitis (EoE) increases the risk of oesophageal cancer (OCa) remains understudied.To assess whether adults with EoE were more likely to have subsequent OCa diagnosis.This case–control study used data from the MarketScan commercial claims database. Cases were 18–64 years old with an oesophageal cancer diagnosis (≥ two coding instances) who had no previous oesophageal cancer code. Controls were matched 10:1 by age and time in health plan. All cases and controls had at least 2 years of continuous healthcare coverage before the index date. EoE status required ≥ two coding instances. We used conditional logistic regression modelling to assess the association between EoE and oesophageal cancer.Of 5562 eligible cases and 55,620 matched controls, median age was 58.8 years and median number of years in health plan was 5.1. The proportions of male cases and controls were 81.3% and 41.4%, respectively. A history of EoE was rare in both cases and controls. Only two oesophageal cancer cases (0.04%) and 44 controls (0.08%) had evidence of an EoE diagnosis (OR 0.46; 95% CI 0.11–1.88).EoE is not associated with the development of oesophageal cancer in privately insured adults under 65 years old; co‐incidence of EoE and oesophageal cancer is extremely rare. Additional studies are needed to confirm these findings and to evaluate whether they hold in older adults or over longer follow‐up, and whether EoE might protect against oesophageal cancer.

Purpose: Oesophaegal cancer patients with a clinical complete response (CR) after neoadjuvant chemoradiotherapy (nCRT) are candidates for an active surveillance strategy. Regrowth rates of 40% after initial clinical CR indicate that identification of a true complete response to nCRT remains challenging. Near-infrared tumour-specific fluorescence endoscopic imaging might help to discriminate patients with a true complete response from patients with residual disease. This study aims to find potential markers to enable molecular imaging in oesophageal cancer and to assess the effect of nCRT on marker expression. Procedures: Oesophageal cancer tissue slides of diagnostic biopsies (n = 41) (pre-treatment) and paired surgical specimens (n = 31) (post-treatment) were collected. Tissue slides of patients with adenocarcinoma (n = 29) and squamous cell carcinoma (n = 12)) were included. Immunohistochemistry was performed to assess expression of the tumour markers CEA, EpCAM, VEGF-α, EGFR, and c-MET in the tumour and compared to the expression of these markers in surrounding healthy tissue. A total immunostaining score (TIS, range 0–12), which combines the percentage and intensity of stained cells, was calculated. The TIS of pre-treated biopsies were compared with the TIS of the post-treatment surgical specimens to assess the effect of neoadjuvant therapy on the marker expression. Results: The median TIS of EpCAM in adenocarcinomas was 10, vs. 0 in healthy mucosa (p < 0.001). The median TIS of EGFR in squamous cell carcinoma was 12, vs. 4 in healthy mucosa (p < 0.001). Neoadjuvant therapy did not affect the expression of the markers. Conclusion: EpCAM and EGFR appear to be the most suitable targets for tumour-specific NIR fluorescence imaging of oesophageal adenocarcinoma and squamous cell carcinoma, respectively. Unaffected expression of all suitable markers by neoadjuvant therapy implies that the diagnostic biopsy can be used to select a patient-specific target for response evaluation by molecular imaging.

The aim of our study was to assess the inter-observer variability in delineation of the gross tumour volume (GTV) of oesophageal cancer on magnetic resonance (MR) in comparison to computed tomography (CT) and positron emission tomography and CT (PET/CT). Twenty-three consecutive patients with oesophageal cancer treated with chemo-radiotherapy were enrolled. All patients had PET/CT and MR imaging in treatment position. Five observers independently delineated the GTV on CT alone, MR alone, CT with co-registered MR, PET/CT alone and MR with co-registered PET/CT. Volumes of GTV were measured per patient and imaging modality. Inter-observer agreement, expressed in generalized conformity index (CIgen), volumetric conformity index (VCI), planar conformity index (PCI) and inter-delineation distance (IDD) were calculated per patient and imaging modality. Linear mixed models were used for statistical analysis. GTV volume was significantly lower on MR (33.03 cm3) compared to CT (37.1 cm3; p = 0.002) and on PET/CT MR (35.2 cm3; p = 0.018) compared to PET/CT (39.1 cm3). The CIgen was lowest on CT (0.56) and highest on PET/CT MR (0.67). The difference in CIgen between MR (0.61) and CT was borderline significant (p = 0.048). The VCI was significantly higher on MR (0.71; p = 0.007) and on CT MR (0.71; p = 0.004) compared to CT (0.67). The PCI was significantly higher on CT MR (0.67; p = 0.031) compared to CT (0.64). The largest differences were observed in the cranio-caudal direction. The highest inter-observer agreement was found for PET/CT MR and the lowest for CT. MR could reduce the difference in delineation between observers and provide additional information about the local extent of the tumour. [ABSTRACT FROM AUTHOR]

Simple Summary: Anastomotic leakage (AL) has a reported incidence of up to 53% and contributes to a high morbidity and mortality after oesophagectomy. Because of its high success rates, endoluminal vacuum-assisted closure therapy (EVAC) is nowadays the standard treatment for AL. However, its effectiveness depends upon different factors. As most patients receive trimodal therapy (neoadjuvant therapy, followed by surgery and adjuvant therapy) due to their preoperative cancer staging, the question arises as to whether neoadjuvant therapy impacts the success rate of EVAC. Therefore, our aim was to identify any adverse effects of a neoadjuvant therapy on EVAC compared to no prior treatment, in order to improve patient care and treatment algorithms. We found no significant influence of neoadjuvant therapy on EVAC. Furthermore, EVAC proved to be an effective and secure treatment option, leading to no changes in the management of AL for now. Background: Anastomotic leakage (AL) is a dreaded complication after oesophagectomy. Endoluminal vacuum-assisted closure therapy (EVAC) has been increasingly used as a first-line treatment for AL. We aimed to identify any potential adverse effects of a neoadjuvant therapy (chemotherapy (CT) or radiochemotherapy (RCT)) on EVAC. Methods: We performed a retrospective cohort study at our tertiary centre between 2013 and 2024. All patients who underwent EVAC for AL after oesophagectomy were included in this study. Parameters such as success rate, length of therapy, number of sponges needed, changes in treatment, and survival were analysed. Results: A total of 29 patients were included, 19 of whom received CT/RCT and 10 of whom received no neoadjuvant treatment (NT). There was no significant difference in patient survival (30-day survival rate CT/RCT n = 1 (5.3%) vs. NT n = 1 (10%), p = 0.632), success rate (CT/RCT n = 15 (78.9%) vs. NT n = 9 (90%), p = 0.454), and length of therapy (CT/RCT vs. NT 24.11 vs. 23.8, p = 0.681), the number of sponges required (CT/RCT vs. NT 6.26 vs. 6.6, p = 0.835), and the need for changing treatment (CT/RCT n = 5 (26.3%) vs. NT n = 1 (10%), p = 0.303). Conclusions: NT did not affect the success rate or length of therapy. Thus, we found no significant influence of CT/RCT on EVAC for AL after oesophagectomy. [ABSTRACT FROM AUTHOR]

Objective: To understand the CD8+ tumour infiltrating lymphocyte (TIL) compartment of oesophageal adenocarcinoma (OAC) with regards to markers of lymphocyte exhaustion, tissue residency and to identify possible reasons behind differential responses to therapy. Design: Tumour samples from 44 patients undergoing curative resection for OAC were assessed by flow cytometry for presence of antigen-experienced TILs and markers of activation and exhaustion. Populations of PD-1 and CD39 positive OAC TILs were sorted, and bulk RNA sequencing undertaken using a modified SmartSeq2 protocol. Flow cytometric assessment of functionality was completed. Results: A higher proportion of antigen experienced CD8+ OAC TILs was associated with improved survival following surgery; while, high double positivity (DP) for PD-1 and CD39 among these TILs also correlated significantly with outcome. These DP TILs possess a minority population which is positive for the markers of exhaustion TIM3 and LAG3. Transcriptomic assessment of the PD-1 and CD39 DP TILs demonstrated enrichment for a tissue resident memory T lymphocyte (TRM) phenotype associated with improved survival in other cancers, reinforced by positivity for the canonical TRM marker CD103 by flow cytometry. This population demonstrated maintained functional capacity both in their transcriptomic profile, and on flow cytometric assessment, as well as preserved proliferative capacity. Conclusion: Resected OAC are variably infiltrated by PD-1 and CD39 DP TILs, an abundance of which among lymphocytes is associated with improved survival. This DP population has an increased, but still modest, frequency of TIM3 and LAG3 positivity compared to DN, and is in keeping with a functionally competent TRM phenotype. [ABSTRACT FROM AUTHOR]

Background: Cancer affects not only the person with the disease but those around them. Being a family member is described as strenuous and, often, associated with stress, anxiety and feelings of loneliness. There is a heightened risk of distress for family of those with fast-progressing, severe oesophageal or gastric cancer. Early palliative care involving family is vital yet often overlooked. In order to include family members in early palliative care their management in everyday life needs to be explored. Method: Qualitative inductive interview study using content analysis guided by Graneheim and Lundman. Result: The analysis resulted in the overarching theme "Managing the disease together but still alone". Three categories were identified: Adapting to the disease, Taking control of the situation, Processing emotions. Each category described family members management in various aspects of everyday life together with the ill person and alone. Conclusion: The results may contribute to an awareness of family members' management of large parts of everyday life and, further, their feelings of loneliness, and indicates that family members should be included early in oesophageal or gastric cancer palliative care. Further studies are needed to develop the content of such family-inclusive early palliative care. Summary box: What is already known on this topic Cancer is considered a "we-disease". Being a family member or informal caregiver of someone with cancer is fulfilling but strenuous and family members of those with oesophageal or gastric cancer have an increased risk of prolonged stress. Approximately half of all cancers of the oesophagus or stomach are incurable and the disease course is rapid, with severe symptoms. It is important to include family members in palliative care, which ought to be initiated early. There is currently insufficient knowledge about how family members of persons with incurable oesophageal or gastric cancer manage in everyday life, and also about the palliative care including them that should be provided. What this study adds This study adds an insight into family members' perspective of incurable oesophageal or gastric cancer and how they manage everyday life. It provides information about their management of everyday life, early in the disease course and on many levels, both together with the ill person and alone. How this study might affect research, practice or policy The study could contribute to an awareness in the health care community of how family members manage the disease, which might lead to palliative care inclusion. It also might inspire further studies on how the palliative care could be tailored to family members of those with incurable oesophageal or gastric cancer. [ABSTRACT FROM AUTHOR]

OBJECTIVES Elderly-specific data for multimodal treatment of oesophageal cancer (EC) is lacking. This study aimed to evaluate the safety and efficacy of multimodal treatment in older EC patients and to compare the impact of neoadjuvant chemotherapy (NCT) and neoadjuvant chemoradiotherapy (NCRT). METHODS Patients diagnosed with oesophageal squamous cell carcinoma or adenocarcinoma who received NCT/NCRT were identified in the National Cancer Database (NCDB, 2004–2015). First, we compared baseline and post-treatment characteristics between younger (<70 years) and older patients (≥70 years). Logistic regression was used to investigate risk factors of postoperative mortality. Second, we evaluated the effect of neoadjuvant chemotherapy on postoperative mortality and overall survival in the older cohort. Inverse probability of treatment weights and multivariable analyses were used to compensate for differences in baseline covariates. RESULTS We 1st compared outcomes of neoadjuvant therapy plus oesophagectomy in 14 778 eligible EC patients. The older group experienced higher rates of postoperative mortality at 30 days (5.8%) and 90 days (13.5%) compared to younger patients. Postoperative mortality was significantly related to the Charlson–Deyo score and treatment-related factors including neoadjuvant therapy type and minimally invasive technique. Second, among the 3141 older patients (with a median follow-up of 57.8 months and 2029 deaths), those receiving NCT obtained significantly lower postoperative mortality and improved overall survival compared with NCRT (inverse probability of treatment weights-adjusted P  = 0.05; hazard ratio 0.85; 95% Cl 0.72–0.99). CONCLUSIONS Neoadjuvant therapy plus oesophagectomy carries increased short-term mortality risk in older EC patients. NCT in older EC patients showed lower postoperative mortality but no statistically significant differences in overall survival, with a point estimate favouring NCT compared to the NCRT group, making NCT a potential option for consideration in specific cases.

Background: Quality performance indicators for the management of oesophagogastric cancer can be used to objectively measure and compare the performance of individual units and capture key elements of patient care to improve patient outcomes. Methods: Two systematic reviews were completed to identify evidence‐based quality performance indicators for the surgical management of oesophagogastric cancer. Based on the indicators identified, a two‐round modified Delphi process with invitations was sent to all members of the Australia and Aotearoa New Zealand Gastric and Oesophageal Surgery Association. The expert working group discussed each suggested indicator and either removed, added, or adjusted the list of indicators of oesophagogastric cancer. Results: The final list of both OG cancer indicators included Specialized Multi‐disciplinary team discussion, Endoscopy documentation, Staging Contrast CT Chest/Abdomen and Pelvis, Neoadjuvant or Adjuvant chemo/radiotherapy administered in accordance with the Local multi‐disciplinary team, Pathological margin clearance (R0 Resection), Lymphadenectomy retrieving 15 or more nodes, Formal review of pathological findings and documentation, Postoperative complications, 30‐day and 90‐day postoperative mortality, clinical surveillance and Specialized Dietetic guidance. Indicators specific to gastric cancer included Preoperative biopsy for pathological diagnosis and Staging Laparoscopy. Indicators specific to oesophageal cancer include positron emission tomography scan if CT negative for metastasis, Perioperative Oesophagectomy Care Pathway, length of stay of 21 days or more, and Unplanned readmission within 30 days. Conclusions: The results of this study present a core set of indicators for the surgical management of oesophagogastric cancer that can be used to measure quality and compare performance between different units.

Aim: To examine the level and influencing factors of discharge readiness among patients with oesophageal cancer following oesophagectomy and to explore its association with post‐discharge outcomes (post‐discharge coping difficulty and unplanned readmission). Background: Oesophageal cancer is common and usually treated via oesophagectomy in China. The assessment of patient's discharge readiness gradually attracts attention as patients tend to be discharged more quickly. Design: Prospective observational study. The STROBE statement was followed. Methods: In total, 154 participants with oesophageal cancer after oesophagectomy were recruited in a tertiary cancer centre in Southern China from July 2019 to January 2020. The participants completed a demographic and disease‐related questionnaire, the Quality of Discharge Teaching Scale and Readiness for Hospital Discharge Scale before discharge. Post‐discharge outcomes were investigated on the 21st day (post‐discharge coping difficulty) and 30th day (unplanned readmission) after discharge separately. Multiple linear regressions were used for statistical analysis. Results: The mean scores of discharge readiness and quality of discharge teaching were (154.02 ± 31.58) and (138.20 ± 24.20) respectively. The quality of discharge teaching, self‐care ability, dysphagia and primary caregiver mainly influenced patient's discharge readiness and explained 63.0% of the variance. The low discharge readiness could predict more risk of post‐discharge coping difficulty (r = −0.729, p < 0.01) and unplanned readmission (t = −2.721, p < 0.01). Conclusions: Discharge readiness among patients with oesophageal cancer following oesophagectomy is influenced by various factors, especially the quality of discharge teaching. A high discharge readiness corresponds to good post‐discharge outcomes. Implications for the Profession and Patient Care: Healthcare professionals should improve the discharge readiness by constructing high‐quality discharge teaching, cultivating patients' self‐care ability, mobilizing family participation and alleviating dysphagia to decrease adverse post‐discharge outcomes among patients with oesophageal cancer. Patients or Public Contribution: Patients with oesophageal cancer after oesophagectomy who met the inclusion criteria were recruited. [ABSTRACT FROM AUTHOR]

Abstract Background The purpose of the study is to examine if prolonged thromboprophylaxis decreases the risk of thrombosis after intended curative surgery for oesophageal cancer. Study results are expected to inform a guideline for thromboprophylaxis after oesophageal cancer surgery. The perspective is to reduce morbidity and mortality in this critically ill patient group. Thrombosis is the second-most common cause of cancer death after the cancer itself. The risk of thrombosis depends on the cancer type, and upper gastrointestinal cancers are considered high risk. This risk is further increased when patients undergo surgery. However, only few studies have investigated the peri- and postoperative coagulation profile in oesophageal cancer patients. Due to this lack of knowledge, prophylaxis is currently restricted to 5000 IU (international units) low-molecular weight heparin daily from surgery until discharge from hospital (approximately 10 days), whereas patients with gastric cancer receive 30 days of treatment. The present study examines whether a 30-day treatment is superior and safe, compared with the current standard treatment. Methods The study is a randomised controlled trial. Inclusion is ongoing, and we aim to include 100 patients. Blood samples are drawn before and after surgery, and the coagulation is extensively examined. The primary endpoint is the difference in plasma levels of prothrombin fragment 1 + 2 (F1 + 2) 30 days after surgery between the intervention and the standard group. Furthermore, patients are examined with ultrasound to screen for asymptomatic venous thrombotic events (VTE). Secondary endpoints are incidence of bleeding, symptomatic and asymptomatic VTE and mortality 30 days 1 one year after surgery. Discussion The study will provide valuable information on the perioperative coagulation profile and VTE risk of oesophageal cancer patients. The study seeks to aid in optimising the postoperative thromboprophylaxis, and the perspective is to reduce morbidity and mortality in this at-risk patient population. Trials registration The trial was prospectively registered at the EU Clinical Trials Register with ID 2021–001335-24 on 30 June 2021 and at ClinicalTrials.gov with study identifier NCT05067153.

The chain mediation analysis was conducted using SPSS PROCESS Macro Model 6.Results: Mediation analysis showed that symptom interference indirectly influenced life satisfaction through two significant mediating pathways: (i) resilience (B = − 0.138, 95% CI: − 0.194 to − 0.091); (ii) the chain mediators involving in resilience and family support (B = − 0.049, 95% CI: − 0.073 to − 0.026). Surprisingly, the mediating pathway of family support was not significant.Conclusion: Interventions for resilience and family support could mitigate the adverse effects of symptom interference in patients after esophagectomy, improving life satisfaction. Of these, resilience may be more critical in terms of the utilization of social resources than family support.Keywords: life satisfaction, oesophageal cancer, social support, resilience, symptom interference

Abstract Background Oesophageal cancer remains a challenging disease with high mortality rates and few therapeutic options. In view of these difficulties, epigenetic drugs have emerged as potential alternatives for patient care. The goal of this study was to evaluate the effect and biological consequences of Panobinostat treatment, an HDAC (histone deacetylase) inhibitor already approved for treatment of patients with multiple myeloma, in oesophageal cell lines of normal and malignant origin, with the latter being representative of the two main histological subtypes: adenocarcinoma and squamous cell carcinoma. Results Panobinostat treatment inhibited growth and hindered proliferation, colony formation and invasion of oesophageal cancer cells. Considering HDAC tissue expression, HDAC1 was significantly upregulated in normal oesophageal epithelium in comparison with tumour tissue, whereas HDAC3 was overexpressed in oesophageal cancer compared to non-malignant mucosa. No differences between normal and tumour tissue were observed for HDAC2 and HDAC8 expression. Conclusions Panobinostat exposure effectively impaired malignant features of oesophageal cancer cells. Because HDAC3 was shown to be overexpressed in oesophageal tumour samples, this epigenetic drug may represent an alternative therapeutic option for oesophageal cancer patients.

Objective: Despite several observational studies attempting to investigate the potential association between type 1 diabetes mellitus (T1DM) and the risk of digestive cancers, the results remain controversial. The purpose of this study is to examine whether there is a causal relationship between T1DM and the risk of digestive cancers. Methods: We conducted a Mendelian randomisation (MR) study to systematically investigate the effect of T1DM on six most prevalent types of digestive cancers (oesophageal cancer, stomach cancer, hepatocellular carcinoma, biliary tract cancer, pancreatic cancer, and colorectal cancer). A total of 1,588,872 individuals were enrolled in this analysis, with 372,756 being the highest number for oesophageal cancer and 3,835 being the lowest for pancreatic cancer. Multiple MR methods were performed to evaluate the causal association of T1DM with the risk of six site-specific cancers using genome-wide association study summary data. Sensitivity analyses were also conducted to assess the robustness of the observed associations. Results: We selected 35 single nucleotide polymorphisms associated with T1DM as instrumental variables. Our findings indicate no significant effect of T1DM on the overall risk of oesophageal cancer (OR= 0.99992, 95% CI: 0.99979-1.00006, P= 0.2866), stomach cancer (OR=0.9298,95% CI: 0.92065-1.09466, P= 0.9298), hepatocellular carcinoma (OR= 0.99994,95% CI: 0.99987-1.00001, P= 0.1125), biliary tract cancer (OR=0.97348,95% CI: 0.8079-1.1729, P= 0.7775)), or pancreatic cancer (OR =1.01258, 95% CI: 0.96243-1.06533, P= 0.6294). However, we observed a causal association between T1DM and colorectal cancer (OR=1.000, 95% CI: 1.00045-1.0012, P<0.001), indicating that T1DM increases the risk of colorectal cancer. We also performed sensitivity analyses, which showed no heterogeneity or horizontal pleiotropy. For the reverse MR from T1DM to six digestive cancers, no significant causal relationships were identified. Conclusions: In this MR study with a large number of digestive cancer cases, we found no evidence to support the causal role of T1DM in the risk of oesophageal cancer, stomach cancer, hepatocellular carcinoma, biliary tract cancer, or pancreatic cancer. However, we found a causal positive association between T1DM and colorectal cancer. Further large-scale prospective studies are necessary to replicate our findings. [ABSTRACT FROM AUTHOR]

Aim Background Design Methods Results Conclusion Impact Reporting Method Patient or Public Contribution To assess early postoperative core symptoms in oesophageal cancer patients and their relationship with resilience.Patients with oesophageal cancer face a high number of severe symptoms in the early post‐operative period and require the development of an effective symptom management programme. Identifying core symptoms through network analysis helps in accurate patient care.A multicentre cross‐sectional study.A cross‐sectional survey was conducted from August 2022 to August 2023 at three hospitals in Anhui Province, China. A total of 469 patients were recruited for this study and 418 (89.1%) patients completed this investigation. Using network analysis to find early post‐operative core symptoms in oesophageal cancer patients. Multiple linear regression was used to analyse resilience factors affecting core symptoms.Sadness was the most core symptom in oesophageal cancer patients in the early post‐operative period (rs = 1.41), followed by incision pain and difficulty breathing while resting (rs = 1.20, rs = 1.08). Resilience was significantly associated with patients' feelings of sadness, with optimism having the greatest impact on sadness (p < .01).Sadness is the most core symptom in patients in the early post‐operative period and special attention should be paid to improving their level of resilience. Local symptoms and dysfunction in the early post‐operative period should be treated in a synergistic manner.This study identifies core symptoms and their relationship to resilience in patients with oesophageal cancer in the early post‐operative period. Symptoms as the main core symptom in patients in the early post‐operative period, which was sadness and was significantly associated with resilience. Precise interventions can be made to target patients' core post‐operative symptoms, which can help improve the effectiveness of symptom management.We have complied with the relevant EQUATOR research reporting checklist.No patient or public contribution in the study.

OBJECTIVES Patients undergoing thoracic surgery experience high complication rates. It is uncertain whether preoperative health-related quality of life (HRQOL) measurements can predict patients at higher risk for postoperative complications. The objective of this study was to determine the association between preoperative HRQOL and postoperative complications among patients undergoing thoracic surgery. METHODS This was a retrospective cohort study of prospectively collected data. Consecutive patients undergoing elective thoracic surgery at a Canadian tertiary care centre between January 2018 and January 2019 were included. Patient HRQOL was measured using the Euroqol-5 Dimension (EQ-5D) survey. Complications were recorded using the Ottawa Thoracic Morbidity and Mortality system. Uni- and multivariable analysis were performed. RESULTS Of 515 surgeries performed, 133 (25.8%) patients experienced at least 1 postoperative complication; 345 (67.0%) patients underwent surgery for malignancy. A range of 271 (52.7%) to 310 (60.2%) patients experienced pain/discomfort at each timepoint. On multivariable analysis, lower preoperative EQ-5D visual analogue scale scores were significantly associated with postoperative complications (adjusted odds ratio 0.97, 95% confidence interval 0.95–0.99; P  =   0.01). Presence of malignancy was not independently associated with complications (P  =   0.68). CONCLUSIONS Self-reported preoperative HRQOL can predict incidence of postoperative complications among patients undergoing thoracic surgery. Assessments of preoperative HRQOL may help identify patients at higher risk for developing complications. These findings could be used to direct preoperative risk-mitigation strategies in areas of HRQOL where patients suffer most, such as pain. The full perioperative trajectory of patient HRQOL should be discerned to identify subsets of patients who share common risk factors. [ABSTRACT FROM AUTHOR]

Oesophageal cancer (EC) is a malignancy which accounts for a substantial number of cancer‐related deaths worldwide. The molecular mechanisms underlying the pathogenesis of EC have not been fully elucidated. GSE17351 and GSE20347 data sets from the Gene Expression Omnibus (GEO) database were employed to screen differentially expressed genes (DEGs). Reverse transcription quantitative PCR (RT‐qPCR) was used to examine hub gene expression. ECA‐109 and TE‐12 cells were transfected using the pcDNA3.1 expression vector encoding GABRP. The cell counting kit‐8 (CCK‐8), cell scratch and Transwell assays were performed to assess the effect of GABRP on EC cell proliferation, migration and invasion. Epithelial‐mesenchymal transition (EMT)‐associated protein levels were measured by Western blotting. Subsequently, CFTR was knocked down to verify whether GABRP affected biological events in EC cells by targeting CFTR. Seven hub genes were identified, including GABRP, FLG, ENAH, KLF4, CD24, ABLIM3 and ABLIM1, which all could be used as diagnostic biomarkers for EC. The RT‐qPCR results indicated that the expression levels of GABRP, FLG, KLF4, CD24, ABLIM3 and ABLIM1 were downregulated, whereas the expression level of ENAH was upregulated. In vitro functional assays demonstrated that GABRP overexpression suppressed the proliferation, migration, invasion and EMT of EC cells. Mechanistically, GABRP promoted the expression of CFTR, and CFTR knockdown significantly counteracted the influence of GABRP overexpression on biological events in EC cells. Overexpression of GABRP inhibited EC progression by increasing CFTR expression, which might be a new target for EC treatment. [ABSTRACT FROM AUTHOR]

Simple Summary: Oesogastric cancers are often diagnosed at a locally advanced stage, especially in western countries. Thus, their prognosis is highly influenced by correct staging and response rate to preoperative therapy. Radiomics may offer a promising tool for improving the quality of current diagnostics of these tumors. Radiomic predictive models seem to work best when integrated with clinical characteristics. As a future perspective, the incorporation of molecular subgroup analysis to clinical and radiomic characteristics could even increase the effectiveness of these predictive and prognostic models. Background: Oesophageal, gastroesophageal, and gastric malignancies are often diagnosed at locally advanced stage and multimodal therapy is recommended to increase the chances of survival. However, given the significant variation in treatment response, there is a clear imperative to refine patient stratification. The aim of this narrative review was to explore the existing evidence and the potential of radiomics to improve staging and prediction of treatment response of oesogastric cancers. Methods: The references for this review article were identified via MEDLINE (PubMed) and Scopus searches with the terms "radiomics", "texture analysis", "oesophageal cancer", "gastroesophageal junction cancer", "oesophagogastric junction cancer", "gastric cancer", "stomach cancer", "staging", and "treatment response" until May 2024. Results: Radiomics proved to be effective in improving disease staging and prediction of treatment response for both oesophageal and gastric cancer with all imaging modalities (TC, MRI, and 18F-FDG PET/CT). The literature data on the application of radiomics to gastroesophageal junction cancer are very scarce. Radiomics models perform better when integrating different imaging modalities compared to a single radiology method and when combining clinical to radiomics features compared to only a radiomics signature. Conclusions: Radiomics shows potential in noninvasive staging and predicting response to preoperative therapy among patients with locally advanced oesogastric cancer. As a future perspective, the incorporation of molecular subgroup analysis to clinical and radiomic features may even increase the effectiveness of these predictive and prognostic models.

The therapeutic possibilities of endoscopy have rapidly increased in the last decades and now allow organ-sparing treatment of early upper gastrointestinal malignancy as well as an increasing number of options for symptom palliation. This review contains an overview of the interventional endoscopic procedures in upper gastrointestinal malignancies. It describes endoscopic treatment of early oesophageal and gastric cancers, and the palliative options in managing dysphagia and gastric outlet obstruction. It also provides an overview of the therapeutic possibilities of biliary endoscopy, such as retrograde stenting and radiofrequency biliary ablation. Endoscopic ultrasound-guided therapeutic options are discussed, including biliary drainage, gastrojejunostomy and coeliac axis block. To aid in clinical decision making, the procedures are described in the context of their indication, efficacy, risks and limitations. • Endoscopy now offers curative treatments for early oesophageal and gastric cancer. • Interventional endoscopy can offer effective symptom palliation for dysphagia, pain and jaundice. • Duodenal stents and EUS-guided interventions provide effective palliation in gastric obstruction.

AbstractPurposeMethodResultConclusionThe impact of long-term aerodigestive symptoms following oesophageal cancer surgery is still not well understood. This study aimed to qualitatively understand the long-term impact of aerodigestive symptoms on quality of life in adults post-oesophagectomy.Participants who received curative transhiatal/transthoracic surgery for oesophageal cancer in Ireland’s National Oesophageal Cancer Centre were invited to attend semi-structured interviews. Surgery had to be completed at least 12 months prior. Reflexive thematic analysis was conducted.Forty participants were interviewed individually face-to-face. Four key themes were identified: (a) isolation, reflecting the reported solitude experienced by oesophageal cancer survivors when attempting to manage their ongoing aerodigestive symptoms; (b) fear, including fear of choking and fear that dysphagia symptoms may indicate recurrence of oesophageal cancer; (c) altered work capacity, caused by ongoing aerodigestive symptoms; and (d) avoidance of social situations involving food, due to the pain, discomfort, and embarrassment caused by these symptoms.Oesophageal cancer treatment can be lifesaving, however, such medical interventions can result in distressing physiological aerodigestive symptoms throughout survivorship, which can significantly impact quality of life. Our findings indicate a need for greater community support to manage aerodigestive symptoms and reduce the impact these have on quality of life. [ABSTRACT FROM AUTHOR]

Aim: The primary objective was to assess the relationship between the citation number and the quality of the articles, as compared with the level of evidence and the MINORS score. This study's secondary objective was to characterize the 50 most cited articles in the field of oesophagectomy research. Background: There has been an increased need for an evaluation tool to indicate research quality. Available quality assessment tools include the Level of Evidence, the MINORS score, the Cochrane Risk of Bias 2.0 Tool, the Newcastle Ottawa Scale, CASP Appraisal Checklists, and Legend Evidence Evaluation tools. Methods: The Web of Science allowed evaluating and comparing articles on oesophagectomy research. The quality of the 50 most cited articles was assessed using the Oxford Centre level of evidence classification and the methodological index for non-randomized studies (MINORS). Results: Level of evidence II studies were cited more than level IV (P=0.008). There was a significant positive correlation between citation number and MINORS score (P=0.002). The median MINORS score was highest amongst level II studies, followed by levels III, IV, and I. The median MINORS score for level II evidence was significantly higher than for level IV (P=0.001). The study sample size is associated with higher levels of evidence but does not correlate with the citation number. Female authors contributed to 4 out of 50 articles. Recently published articles tended to be cited more frequently. More authors equated to more citations. Prospective studies are more likely to be cited. Conclusion: Citation analysis can be used as an indicator of quality when assessing articles. It should, however, be used with caution as highly cited work, famous authors, and journals are all more likely to be cited. Citation analysis should be used alongside other well-established tools.

OBJECTIVES Unlike the initial plan, some patients with oesophageal squamous cell carcinoma cannot or do not receive surgery after neoadjuvant chemoradiotherapy (nCRT). This study aimed to report the epidemiology of patients not receiving surgery after nCRT and to evaluate the potential risk of refusing surgery. METHODS We analysed patients with clinical stage T3-T4aN0M0 or T1-T4aN1-N3M0 oesophageal squamous cell carcinoma who underwent nCRT as an initial treatment intent between January 2005 and March 2020. Patients not receiving surgery were categorized using predefined criteria. To evaluate the risk of refusing surgery, a propensity-matched comparison with those who received surgery was performed. Recurrence-free (RFS) and overall survival (OS) was compared between groups, according to clinical response to nCRT. RESULTS Among the study population (n  = 715), 105 patients (14.7%) eventually failed to reach surgery. There were three major patterns of not receiving surgery: disease progression before surgery (n  = 25), functional deterioration at reassessment (n  = 47), and patient's refusal without contraindications (n  = 33). After propensity-score matching, the RFS curves of the surgery group and the refusal group were significantly different (P  <   0.001), while OS curves were not significantly different (P  =   0.069). In patients who achieved clinical complete response on re-evaluation, no significant difference in the RFS curves (P  =   0.382) and in the OS curves (P  =   0.290) was observed between the surgery group and the refusal group. However, among patients who showed partial response or stable disease on re-evaluation, the RFS and OS curves of the refusal group were overall significantly inferior compared to those of the surgery group (both P  <   0.001). The 5-year RFS rates were 10.3% for the refusal group and 48.2% for the surgery group, and the 5-year OS rates were 8.2% for the refusal group and 46.1% for the surgery group. CONCLUSIONS Patient's refusal remains one of the major obstacles in completing the trimodality therapy for oesophageal squamous cell carcinoma. Refusing surgery when offered may jeopardize oncological outcome, particularly in those with residual disease on re-evaluation after nCRT. These results provide significant implications for consulting patients who are reluctant to oesophagectomy after nCRT. [ABSTRACT FROM AUTHOR]

There has been limited progress made in improving the suboptimal outcomes delivered by conventionally fractionated radiotherapy (RT) for oesophageal adenocarcinoma (OAC) and squamous cell carcinoma (OSCC). A greater biological effect may be achieved using hypofractionated RT (HFRT), though the toxicity, tolerability and efficacy of this approach in OAC and OSCC is uncertain. A systematic literature review was carried out in accordance with Preferred Reporting Items for Systematic Reviews guidance. Medline, EMBASE, PubMed, Cochrane, CINAHL, Scopus and Web of Science databases were searched for terms relating to HFRT (>2.4Gy per fraction) for OAC or OSCC. All relevant clinical studies published between January 2000 and April 2023 were included. Study quality was assessed using predefined criteria. Ninety-six studies were screened and 20 subsequently included, together incorporating 1208 patients. Fourteen studies focussed on neoadjuvant or definitive treatment. These were predominantly retrospective (n = 10, 71%) though two (n = 2, 14%) early phase trials were identified. Most focussed on OSCC (n = 7, 47%) or mixed OSCC/OAC (n = 6, 43%) populations. Four (28.6%) included a conventionally fractionated chemoradiotherapy (CRT) comparator, against which median overall (mOS) and progression free survival outcomes from HFRT did not differ. Reported mOS for HFRT ranged between 29-36 months at 2.5–3.125Gy per fraction (total dose 50–60Gy) for OAC and OSCC combined. Toxicity and tolerability with HFRT was comparable with conventionally fractionated CRT up to, but not exceeding, 5Gy. Three (50%) of the six palliative-intent studies were early phase trials and most (n = 4, 67%) focussed on OAC and OSCC. Response rates with HFRT in the palliative setting were 63.6–88.0%. These data provide evidence in OAC/OSCC for promising efficacy and an acceptable toxicity profile for moderately HFRT, alone or with concurrent chemotherapy. These data should prompt prospective, randomised comparisons of HFRT and conventionally fractionated CRT and single-modality RT schedules. PROSPERO; CRD42023457791. • Hypofractionated radiotherapy has promising efficacy in oesophageal cancer. • Moderately hypofractionated regimens appear well tolerated with reasonable toxicity. • The histological subtype response to hypofractionation is uncertain.

Abstract Background We aimed to identify the impact of muscle mass on locally advanced oesophageal cancer (LAEC) in elderly patients receiving neoadjuvant chemoradiation therapy (NACRT). Methods We reviewed the medical records of 345 patients diagnosed with LAEC who underwent NACRT and surgery. Physical variables, including height, weight, skeletal muscle mass, and laboratory values, were obtained before and after NACRT. Body mass index (BMI, kg/m2), neutrophil‐to‐lymphocyte ratio (NLR), platelet‐to‐lymphocyte ratio (PLR), and prognostic nutritional index (PNI) were calculated as height/(weight)2, ANC/ALC, platelet count/ALC, and (10 × albumin + 0.05 × ALC), respectively. The cutoff for low muscle mass was 43.0 cm2/m2 for BMI below 25 kg/m2 and 53.0 cm2/m2 for BMI 25 kg/m2 or higher. The skeletal muscle index (SMI) was defined as skeletal muscle area/(height)2 (cm2/m2). The ΔSMI (%/50 days) was defined as (SMI after NACRT − SMI before NACRT)/interval (days) × 50 (days) to compare changes over the same period. The excessive muscle loss (EML) group was defined as patients with ΔSMI ≤−10% following NACRT. An elderly patient was defined as aged ≥65 years. The primary outcome measure was overall survival (OS). Results During a median follow‐up of 32.8 months (range, 2.0–176.2), 192 patients died, with a median OS of 50.2 months. Elderly patients did not show inferior OS (young vs. elderly, 57.7% vs. 54.0% at 3 years, P = 0.247). 71.0% and 87.2% of all patients had low muscle mass before and after NACRT, respectively, which was not associated with OS (P = 0.270 and P = 0.509, respectively). Inflammatory (NLR and PLR) and nutritional index (PNI) values or their changes did not correlate with OS. However, the EML group had worse OS (41.6% vs. 63.2% at 3 years, P

Background and Aims: Acute kidney injury (AKI) is a significant postoperative complication. Multiple perioperative factors are implicated in the causation of AKI in the postoperative period in patients with oesophageal cancer. The study aimed to find out the incidence, causes and effects of AKI following oesophagectomy surgery. Methods: A prospective observational study was conducted in consecutive adult patients undergoing elective oesophagectomy at a tertiary cancer care hospital. Patients with preoperative chronic renal insufficiency (serum creatinine >1.5 mg/dl), AKI in the past and a history of renal replacement therapy were excluded. Serum creatinine values were measured on postoperative days 1, 3, 5, the day of discharge or day 15 and on the day of first follow-up or day 28, following oesophagectomy surgery. The incidence of AKI was measured using the ‘Kidney Disease Improving Global Outcome’ (KDIGO) criteria. Results: The incidence of AKI was 14.7% [95% confidence interval (CI) 9.9%, 20.7%] (i.e., 27/183) in patients who underwent elective oesophagectomy. AKI was associated with prolonged hospital stay [median- 13 days (interquartile range {IQR} 11–21.5) versus 9 days (IQR 8–12), P < 0.001] and increased in-hospital mortality (14.8% versus 1.3%, P 0.004, odds ratio = 13.2, 95% CI 2.3, 77.3). After multivariate analysis, age, anastomotic leak and use of vasopressors in the postoperative period were independent predictors of AKI. Conclusion: The incidence of AKI was 14.7% after elective oesophagectomy. AKI was associated with prolonged hospital stay and in-hospital mortality. Higher age, anastomotic leak and use of vasopressors in the postoperative period were independent predictors of AKI.

Abstract Background Previous literature has explored the relationship between chronic atrophic gastritis (CAG) and isolated cancers within the upper gastrointestinal cancers; However, an integrative synthesis across the totality of upper gastrointestinal cancers was conspicuously absent. The research objective was to assess the relationship between CAG and the risk of incident upper gastrointestinal cancers, specifically including gastric cancer, oesophageal cancer, and oesophagogastric junction cancer. Methods Rigorous systematic searches were conducted across three major databases, namely PubMed, Embase and Web of Science, encompassing the timeline from database inception until August 10, 2023. We extracted the necessary odds ratio (OR) and their corresponding 95% confidence interval (CI) for subsequent meta-analysis. Statistical analyses were conducted using Stata 17.0 software. Results This meta-analysis included a total of 23 articles encompassing 5858 patients diagnosed with upper gastrointestinal cancers. CAG resulted in a statistically significant 4.12-fold elevated risk of incident gastric cancer (OR = 4.12, 95% CI 3.20–5.30). Likewise, CAG was linked to a 2.08-fold increased risk of incident oesophageal cancer (OR = 2.08, 95%CI 1.60–2.72). Intriguingly, a specific correlation was found between CAG and the risk of incident oesophageal squamous cell carcinoma (OR = 2.29, 95%CI 1.77–2.95), while no significant association was detected for oesophageal adenocarcinoma (OR = 0.62, 95%CI 0.17–2.26). Moreover, CAG was correlated with a 2.77-fold heightened risk of oesophagogastric junction cancer (OR = 2.77, 95%CI 2.21–3.46). Notably, for the same type of upper gastrointestinal cancer, it was observed that diagnosing CAG through histological methods was linked to a 33–77% higher risk of developing cancer compared to diagnosing CAG through serological methods. Conclusion This meta-analysis indicated a two- to fourfold increased risk of gastric cancer, oesophageal cancer, and oesophagogastric junction cancer in patients with CAG. Importantly, for the same upper gastrointestinal cancer, the risk of incident cancer was higher when CAG was diagnosed histologically compared to serological diagnosis. Further rigorous study designs are required to explore the impact of CAG diagnosed through both diagnostic methods on the risk of upper gastrointestinal cancers.

Abstract Background Surgery is widely regarded as a pivotal therapeutic approach for treating oesophageal cancer, and clinical observations have revealed that many oesophageal cancer patients also present with concomitant hyperlipidaemia. It is surprising that few studies have been performed to determine how blood lipid levels are affected by oesophageal cancer resection. This research was designed to assess the influence of oesophageal cancer resection on lipid profiles among individuals diagnosed with both oesophageal cancer and hyperlipidaemia. Methods A retrospective analysis was carried out on 110 patients with hyperlipidaemia and oesophageal cancer who had undergone oesophagectomy at the 900th Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army. Preoperative and postoperative serological data were collected at seven-, thirty-, sixty-day-, and one-year-long intervals. Changes in lipid levels were compared, the remission of various types of hyperlipidaemia was statistically assessed, and Pearson correlation was used to analyse the association between lipid changes and preoperative body weight. The research sought to assess the reduction in body weight and the proportion of body weight lost one year following surgery. Results Noteworthy decreases were observed in total cholesterol (TC), triglyceride (TG), and low-density lipoprotein (LDL) levels, with TC decreasing from 6.20 mmol/L to 5.20 mmol/L, TG decreasing from 1.40 mmol/L to 1.20 mmol/L, and LDL decreasing from 4.50 mmol/L to 3.30 mmol/L. Conversely, there was a notable increase in high-density lipoprotein (HDL) levels, which increased from 1.20 mmol/L to 1.40 mmol/L (P

Abstract Introduction There are uncertainties surrounding the spectrum of upper gastrointestinal (UGI) diseases in sub-Saharan Africa. This is mainly due to the limitations of data collection and recording. We previously reported an audit of UGI endoscopic diagnoses in Zambia spanning from 1977 to 2014. We now have extended this analysis to include subsequent years, in order to provide a more comprehensive picture of how the diagnoses have evolved over 4 decades. Methods We combined data collected from the endoscopy unit at the University Teaching Hospital (UTH) in Lusaka during a previous review with that collected from the beginning of 2015 to the end of 2021. Since 2015, an electronic data base of endoscopy reports at the UTH was kept. The electronic data base was composed of drop-down menus that allowed for standardised reporting of findings. Collected data were coded by two experienced endoscopists and analysed. Results In total, the analysis included 25,849 endoscopic records covering 43 years. The number of endoscopic procedures performed per year increased drastically in 2010. With the exception of the last 2 years, the proportion of normal endoscopies also increased during the time under review. In total, the number of gastric cancer (GC) cases was 658 (3%) while that of oesophageal cancer (OC) was 1168 (5%). The number of GC and OC diagnoses increased significantly over the period under review, (p

Methylated circulating tumour DNA (ctDNA) blood tests for BCAT1/IKZF1 (COLVERA) and SEPT9 (Epi proColon) are used to detect colorectal cancer (CRC). However, there are no ctDNA assays approved for other gastrointestinal adenocarcinomas. We aimed to characterize BCAT1, IKZF1 and SEPT9 methylation in different gastrointestinal adenocarcinoma and non-gastrointestinal tumours to determine if these validated CRC biomarkers might be useful for pan-gastrointestinal adenocarcinoma detection. Tissue DNA methylation data from colorectal (COAD, READ), gastroesophageal (ESCA, STAD), pancreatic (PAAD) and cholangiocarcinoma (CHOL) adenocarcinoma cohorts within The Cancer Genome Atlas were used for differential methylation analyses. Clinicodemographic predictors of BCAT1, IKZF1 and SEPT9 methylation, and the selectivity of hypermethylated BCAT1, IKZF1 and SEPT9 for colorectal adenocarcinomas in comparison to other cancers were each explored with beta regression. Hypermethylated BCAT1, IKZF1 and SEPT9 were each differentially methylated in colorectal and gastroesophageal adenocarcinomas. IKZF1 was differentially methylated in pancreatic adenocarcinoma. Hypermethylated DNA biomarkers BCAT1, IKZF1 and SEPT9 were largely stable across different stages of disease and were highly selective for gastrointestinal adenocarcinomas relative to other cancer types. Existing CRC methylated ctDNA blood tests for BCAT1/IKZF1 and SEPT9 might be usefully repurposed for use in other gastrointestinal adenocarcinomas and warrant further prospective ctDNA studies.

It is unclear how metabolomic age is associated with the risk of a wide range of chronic diseases. Our analysis included 110,692 participants (training: n = 27,673; testing: n = 27,673; validating: n = 55,346) aged 39–71 years at baseline (2006–2010) from the UK Biobank. Incident chronic diseases were identified using inpatient records, or death registers until January 2021. Predicted metabolomic age was trained and tested based on 168 metabolomics. Metabolomic age was linked to the risk of 50 diseases in the validation dataset. The median follow‐up duration for individual diseases ranged from 11.2 years to 11.9 years. After controlling for false discovery rate, chronological age‐adjusted age gap (CAAG) was significantly associated with the incidence of 25 out of 50 chronic diseases. After adjustment for full covariates, associations with 15 chronic diseases remained significant. Greater CAAG was associated with increased risk of eight cardiometabolic disorders (including cardiovascular diseases and diabetes), some cancers, alcohol use disorder, chronic obstructive pulmonary disease, chronic kidney disease, chronic liver disease and age‐related macular degeneration. The association between CAAG and risk of peripheral vascular disease, other cardiac diseases, fracture, cataract and thyroid disorder was stronger among individuals with unhealthy diet than in those with healthy diet. The association between CAAG and risk of some conditions was stronger in younger individuals, those with metabolic disorders or low education. Metabolomic age plays an important role in the development of multiple chronic diseases. Healthy diet and high education may mitigate the risk for some chronic diseases due to metabolomic age acceleration. [ABSTRACT FROM AUTHOR]

The cardiovascular disease (CVD) burden among patients with oesophageal cancer (EC) treated with curative intent is unclear. To determine CVD incidence and all-cause mortality in patients with EC. Danish national health registries were used to identify patients diagnosed with primary EC between 2008 and 2018. Each EC patient was matched with 10 individuals from the general population. The primary endpoint was a CVD hospital contact (CVD-HC), either admission or outpatient contact. Cox proportional hazard regression models were used to compare the risk of incident CVD-HCs between the cohorts. The study included 1,525 patients with EC and 15,250 individuals from the general population. Patients with EC had a post-diagnosis one-year adjusted hazard ratio (HR) of CVD-HC of 6.1 (95% confidence intervals [CIs] 5.6–6.8) compared with the general population. During the next nine years, the risk of CVD-HC was comparable between the two cohorts, with an adjusted HR of 1.0 (95% CI 0.9–1.3). Patients with EC, and particularly those with prevalent CVD, had a high risk of atrial fibrillation, ischaemic heart disease, and venous thromboembolism within the first year after EC diagnosis. Prevalent CVD among patients with EC was not associated with higher mortality. CVD morbidity was transiently increased in the first year following EC diagnosis compared with the general population. All-cause mortality risks were high but did not appear to be affected by prevalent CVD. The very high risk of CVD in patients with primary EC to be treated with curative intent calls for healthcare initiatives to advance preventive and post-treatment strategies. [ABSTRACT FROM AUTHOR]

Oesophageal cancer (OC) is the sixth leading cause of cancer-related death worldwide. OC is highly aggressive, primarily due to its late stage of diagnosis and poor prognosis for patients' survival. Therefore, the establishment of new biomarkers that will be measured with non-invasive techniques at low cost is a critical issue in improving the diagnosis of OC. In this review, we summarize several original studies concerning the potential significance of selected chemokines and their receptors, including inflammatory proteins such as interleukin-6 (IL-6) and C-reactive protein (CRP), hematopoietic growth factors (HGFs), claudins (CLDNs), matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs), adamalysines (ADAMs), as well as DNA- and RNA-based biomarkers, in OC. The presented results indicate the significant correlation between the CXCL12, CXCR4, CXCL8/CXCR2, M-CSF, MMP-2, MMP-9 ADAM17, ADAMTS-6, and CLDN7 levels and tumor stage, as well as the clinicopathological parameters of OC, such as the presence of lymph node and/or distant metastases. CXCL12, CXCL8/CXCR2, IL-6, TIMP-2, ADAM9, and ADAMTS-6 were prognostic factors for the overall survival of OC patients. Furthermore, IL-6, CXCR4, CXCL8, and MMP-9 indicate higher diagnostic utility based on the area under the ROC curve (AUC) than well-established OC tumor markers, whereas CLDN18.2 can be used in novel targeted therapies for OC patients.

Conversely, there was a notable increase in high-density lipoprotein (HDL) levels, which increased from 1.20 mmol/L to 1.40 mmol/L (P < 0.05) compared to the preoperative levels. Notably, the remission rates for mixed hyperlipidaemia (60.9%) and high cholesterol (60.0%) were considerably greater than those for high triglycerides (16.2%). Alterations in TC at one year postoperatively correlated with preoperative weight and weight loss (r = 0.315, -0.216); changes in TG correlated with preoperative weight, percentage of total weight loss (TWL%), and weight reduction (r = -0.295, -0.246, 0.320); and changes in LDL correlated with preoperative weight, TWL%, and weight loss (r = 0.251, 0.186, and -0.207). Changes in non-high-density lipoprotein(non-HDL) were linked to preoperative weight (r = 0.300), and changes in TG/HDL were correlated with preoperative weight and TWL% (r = -0.424, -0.251). Conclusions: Oesophagectomy significantly improved lipid profiles in oesophageal cancer patients, potentially leading to a reduction in overall cardiovascular risk. [ABSTRACT FROM AUTHOR]

Perioperative music can have beneficial effects on postoperative pain, anxiety, opioid requirement, and the physiological stress response to surgery. The aim was to assess the effects of intraoperative music during general anesthesia in patients undergoing surgery for esophagogastric cancer. The IMPROMPTU study was a double-blind, placebo-controlled, randomized multicenter trial. Adult patients undergoing surgery for stage II-III esophagogastric cancer were eligible. Exclusion criteria were a hearing impairment, insufficient Dutch language knowledge, corticosteroids use, or objection to hearing unknown music. Patients wore active noise-cancelling headphones intraoperatively with preselected instrumental classical music (intervention) or no music (control). Computerized randomization with centralized allocation, stratified according to surgical procedure using variable block sizes, was employed. Primary endpoint was postoperative pain on the first postoperative day. Secondary endpoints were postoperative pain during the first postoperative week, postoperative opioid requirement, intraoperative medication requirement, the stress response to surgery, postoperative complication rate, length of stay, and mortality, with follow-up lasting 30 d. From November 2018 to September 2020, 145 patients were assessed and 83 randomized. Seventy patients (music n = 31, control n = 39) were analyzed. Median age was 70 [IQR 63–70], and 48 patients (69%) were male. Music did not reduce postoperative pain (numeric rating scale 1.8 (SD0.94) versus 2.0 (1.0), mean difference −0.28 [95% CI -0.76–0.19], P = 0.236). No statistically significant differences were seen in medication requirement, stress response, complication rate, or length of stay. Intraoperative, preselected, classical music during esophagogastric cancer surgery did not significantly improve postoperative outcome and recovery when compared to no music using noise-cancelling headphones.

In total, the number of gastric cancer (GC) cases was 658 (3%) while that of oesophageal cancer (OC) was 1168 (5%). The number of GC and OC diagnoses increased significantly over the period under review, (p < 0.001 for both). For OC the increase remained significant when analysed as a percentage of all procedures performed (p < 0.001). Gastric ulcers (GU) were diagnosed in 2095 (8%) cases, duodenal ulcers (DU) in 2276 (9%) cases and 239 (1%) had both ulcer types. DU diagnosis showed a significantly decreasing trend over each decade (p < 0.001) while GU followed an increasing trend (p < 0.001). Conclusions: UGI endoscopic findings in Lusaka, Zambia, have evolved over the past four decades with a significant increase of OC and GU diagnoses. Reasons for these observations are yet to be established. [ABSTRACT FROM AUTHOR]

Background: Although fast-track treatment pathways are well established in colorectal surgeries, their role in oesophageal resections has not been well studied. This study aims to prospectively evaluate the short-term outcomes of enhanced recovery after surgery (ERAS) protocol in patients undergoing minimally invasive oesophagectomy (MIE) for oesophageal malignancy. Patients and Methods: We studied a prospective cohort of 46 consecutive patients from January 2019 to June 2022 who underwent MIE for oesophageal malignancy. The ERAS protocol mainly consists of pre-operative counselling, pre-operative carbohydrate loading, multimodal analgesia, early mobilisation, enteral nutrition and initiation oral feed. Principal outcome measures were the length of post-operative hospital stay, complication rate, mortality rate and 30-day readmission rate. Results: The median (interquartile range [IQR]) age of patients was 49.5 (42, 62) years, and 52.2% were female. The median (IQR) post-operative day of intercoastal drain removal and initiation of oral feed was 4 (3, 4) and 4 (4, 6) days, respectively. The median (IQR) length of hospital stay was 6 (6.0, 7.25) days, with a 30-day readmission rate of 6.5%. The overall complication rate was 45.6%, with a major complication (Clavien-Dindo ≥3) rate of 10.9%. Compliance with the ERAS protocol was 86.9%, and the incidence of major complications was associated with failure to follow the protocol (P = 0.000). Conclusions: ERAS protocol in minimally invasive oesophagectomy is feasible and safe. This may result in early recovery with shortened length of hospital stay without an increase in complication and readmission rates. [ABSTRACT FROM AUTHOR]

Chylothorax is a serious postoperative complication of oesophageal cancer, and to date, there is no standardized and effective intraoperative diagnostic tool that can be used to identify the thoracic duct and determine the location of lymphatic fistulas. A 50-year-old patient with oesophageal squamous cell carcinoma developed chylothorax after thoracolaparoscopy combined with radical resection of oesophageal cancer. Twelve hours after surgery, 1200 mL of clear fluid was drained from the thoracic drainage tube, and a chyle test was sent. A thoracothoracic duct ligation procedure was performed on the first day after surgery. Although fluid accumulating in the posterior mediastinum was observed, the location of the lymphatic fistula could not be determined. During the surgery, indocyanine green (ICG) was injected into the bilateral inguinal lymph nodes, and a fluorescent lens was used to determine the location of the lymphatic fistula so the surgeon could ligate the thoracic duct. ICG fluorescence imaging technology can help surgeons effectively manage chylothorax after oesophageal cancer surgery. To our knowledge, this is the first report to describe the use of ICG fluorescence imaging technology to treat postoperative chylothorax in patients with oesophageal cancer in China.

Abstract Background Food bolus obstruction (FBO) leading to hospital treatment is often associated with eosinophilic oesophagitis (EoE), stenosis, or oesophageal cancer (1). Danish national guidelines recommend that patients with FBO undergo a diagnostic upper endoscopy within two weeks of presentation to exclude possible malignancy, and histological evaluation of eight biopsies (2, 3). Aims The aims of this study were to (1) report the incidence and describe the causes and treatment of FBO in the North Denmark Region (NDR), (2) determine the proportion of patients who underwent upper endoscopy and biopsy according to regional and national guidelines, and (3) identify International Classification of Diseases 10th Revision (ICD-10) diagnosis and procedure codes applied to the hospital visits due to FBO in the NDR. Methods Among all acute hospital visits in the NDR in 2021, all visits with ICD-10 codes possibly reflecting FBO, as well as a random sample of 14,400 visits with unspecific ICD-10 codes (R and Z codes), were screened manually for possible FBO. Diagnosis, follow-up, and treatment of all patients with FBO were recorded. Results The median patient age was 66.0 (Q1-Q3: 49.8–81.0) years, and half of the patients had experienced FBO before. Two thirds of patients (66.0%) were never diagnosed with a cause of FBO, followed by 17.3% with EoE. 30% of patients did not undergo upper endoscopy within two weeks of the hospital visit, and 50.7% were never biopsied in the oesophagus. Of 1886 hospital visits with registry ICD-10 codes that possibly reflected FBO, 8.4% were due to FBO, while FBO was present in 0.028% of the random sample of unspecific ICD-10 codes. Conclusions Most hospitalized FBO patients in the NDR in 2021 were never diagnosed with a cause. In these patients there is a high risk of overlooked EoE or upper gastrointestinal cancers. The area needs immediate focus and changed routines to improve treatment and prevent new FBO.

Background: Although fast-track treatment pathways are well established in colorectal surgeries, their role in oesophageal resections has not been well studied. This study aims to prospectively evaluate the short-term outcomes of enhanced recovery after surgery (ERAS) protocol in patients undergoing minimally invasive oesophagectomy (MIE) for oesophageal malignancy. Patients and Methods: We studied a prospective cohort of 46 consecutive patients from January 2019 to June 2022 who underwent MIE for oesophageal malignancy. The ERAS protocol mainly consists of pre-operative counselling, pre-operative carbohydrate loading, multimodal analgesia, early mobilisation, enteral nutrition and initiation oral feed. Principal outcome measures were the length of post-operative hospital stay, complication rate, mortality rate and 30-day readmission rate. Results: The median (interquartile range [IQR]) age of patients was 49.5 (42, 62) years, and 52.2% were female. The median (IQR) post-operative day of intercoastal drain removal and initiation of oral feed was 4 (3, 4) and 4 (4, 6) days, respectively. The median (IQR) length of hospital stay was 6 (6.0, 7.25) days, with a 30-day readmission rate of 6.5%. The overall complication rate was 45.6%, with a major complication (Clavien–Dindo ≥3) rate of 10.9%. Compliance with the ERAS protocol was 86.9%, and the incidence of major complications was associated with failure to follow the protocol (P = 0.000). Conclusions: ERAS protocol in minimally invasive oesophagectomy is feasible and safe. This may result in early recovery with shortened length of hospital stay without an increase in complication and readmission rates.

Artificial intelligence (AI) and machine learning (ML) systems are increasingly used in medicine to improve clinical decision-making and healthcare delivery. In gastroenterology and hepatology, studies have explored a myriad of opportunities for AI/ML applications which are already making the transition to bedside. Despite these advances, there is a risk that biases and health inequities can be introduced or exacerbated by these technologies. If unrecognised, these technologies could generate or worsen systematic racial, ethnic and sex disparities when deployed on a large scale. There are several mechanisms through which AI/ML could contribute to health inequities in gastroenterology and hepatology, including diagnosis of oesophageal cancer, management of inflammatory bowel disease (IBD), liver transplantation, colorectal cancer screening and many others. This review adapts a framework for ethical AI/ML development and application to gastroenterology and hepatology such that clinical practice is advanced while minimising bias and optimising health equity.
