The overall plant-based diet index(PDI), healthful plant-based diet index(h PDI), and unhealthful plant-based diet index(u PDI), were calculated using survey responses to assess dietary patterns. We applied Cox proportional hazard regression to estimate the multivariable hazard ratios(HRs) and 95% confidence intervals(95% CIs) of EC across 3plant-based diet indices and further stratified the analysis by subgroups.Results: The final study sample included 15,184 participants in the cohort. During a follow-up of 219,365person-years, 176 patients with EC were identified. When the highest quartile was compared with the lowest quartile, the pooled multivariable-adjusted HR of EC was 0.50(95% CI, 0.32-0.77) for h PDI. In addition, the HR per 10-point increase in the h PDI score was 0.42(95% CI, 0.27-0.66) for ECs. Conversely, u PDI was positively associated with the risk of EC, and the HR was 1.80(95% CI, 1.16-2.82). The HR per 10-point increase in the u PDI score was 1.90(95% CI, 1.26-2.88) for ECs. The associations between these scores and the risk of EC were consistent in most subgroups. These results remained robust in sensitivity analyses.Conclusions: A healthy plant-based dietary pattern was associated with a reduced risk of EC. Emphasizing the healthiness and quality of plant-based diets may be important for preventing the development of EC.展开更多

Conversely, u PDI was positively associated with the risk of EC, and the HR was 1.80(95% CI, 1.16-2.82). The HR per 10-point increase in the u PDI score was 1.90(95% CI, 1.26-2.88) for ECs. The associations between these scores and the risk of EC were consistent in most subgroups. These results remained robust in sensitivity analyses.Conclusions: A healthy plant-based dietary pattern was associated with a reduced risk of EC. Emphasizing the healthiness and quality of plant-based diets may be important for preventing the development of EC.

文摘As a highly invasive malignancy,esophageal cancer(EC)is a global health issue,and was the eighth most prevalent cancer and the sixth leading cause of cancerrelated death worldwide in 2020.Due to its highly immunogenic nature,emerging immunotherapy approaches,such as immune checkpoint blockade,have demonstrated promising efficacy in treating EC;however,certain limitations and challenges still exist.In addition,tumors may exhibit primary or acquired resistance to immunotherapy in the tumor immune microenvironment(TIME);thus,understanding the TIME is urgent and crucial,especially given the importance of an immunosuppressive microenvironment in tumor progression.The aim of this review was to better elucidate the mechanisms of the suppressive TIME,including cell infiltration,immune cell subsets,cytokines and signaling pathways in the tumor microenvironment of EC patients,as well as the downregulated expression of major histocompatibility complex molecules in tumor cells,to obtain a better understanding of the differences in EC patient responses to immunotherapeutic strategies and accurately predict the efficacy of immunotherapies.Therefore,personalized treatments could be developed to maximize the advantages of immunotherapy.
文摘BACKGROUND Gastroesophageal reflux disease(GERD)is a common complication of esophageal cancer surgery that can affect quality of life and increase the risk of esophageal stricture and anastomotic leakage.Wendan Decoction(WDD)is a traditional Chinese herbal formula used to treat various gastrointestinal disorders,such as gastritis,functional dyspepsia,and irritable bowel syndrome.Mosapride,a prokinetic agent,functions as a selective 5-hydroxytryptamine 4 agonist,enhancing gastrointestinal motility.AIM To evaluate the therapeutic effects of WDD combined with mosapride on GERD after esophageal cancer surgery.METHODS Eighty patients with GERD were randomly divided into treatment(receiving WDD combined with mosapride)and control(receiving mosapride alone)groups.The treatment was conducted from January 2021 to January 2023.The primary outcome was improved GERD symptoms as measured using the reflux disease questionnaire(RDQ).The secondary outcomes were improved esophageal motility(measured using esophageal manometry),gastric emptying(measured using gastric scintigraphy),and quality of life[measured via the Short Form-36(SF-36)Health Survey].RESULTS The treatment group showed a notably reduced RDQ score and improved esophageal motility parameters,such as lower esophageal sphincter pressure,peristaltic amplitude,and peristaltic velocity compared to the control group.The treatment group showed significantly higher gastric emptying rates and SF-36 scores(in both physical and mental domains)compared to the control group.No serious adverse effects were observed in either group.CONCLUSION WDD combined with mosapride is an effective and safe therapy for GERD after esophageal cancer surgery.It can improve GERD symptoms,esophageal motility,gastric emptying,and the quality of life of patients.Further studies with larger sample sizes and longer follow-up periods are required to confirm these findings.
文摘Helicobacter pylori(H.pylori)infection affects a substantial proportion of the global population and causes various gastric disorders,including gastric cancer.Recent studies have found an inverse relationship between H.pylori infection and eso-phageal cancer(EC),suggesting a protective role against EC.This editorial focuses on the possible mechanisms underlying the role of H.pylori infection in EC and explores the role of gut microbiota in esophageal carcinogenesis and the prac-ticality of H.pylori eradication.EC has two major subtypes:Esophageal squamous cell carcinoma(ESCC)and esophageal adenocarcinoma(EAC),which have different etiologies and risk factors.Gut microbiota can contribute to EC via inflammation-induced carcinogenesis,immunomodulation,lactagenesis,and genotoxin production.H.pylori infection is said to be inversely related to EAC,protecting against EAC by inducing atrophic gastritis,altering serum ghrelin levels,and triggering cancer cell apoptosis.Though H.pylori infection has no significant association with ESCC,COX-2-1195 polymorphisms and endogenous nitrosamine production can impact the risk of ESCC in H.pylori-infected in-dividuals.There are concerns regarding a plausible increase in EC after H.pylori eradication treatments.However,H.pylori eradication is not associated with an increased risk of EC,making it safe from an EC perspective.
文摘This article reviews the cohort study published in the World Journal of Gastroenterology,which reported low rates of Helicobacter pylori(H.pylori)infection among esophageal cancer(EC)patients,coupled with proton pump inhibitor(PPI)overuse.These findings suggest a potential protective role of H.pylori against EC and indicate a possible association between PPI use and increased cancer risk.In light of these findings,our article examines the complex relationship between H.pylori and esophageal precancerous lesions,exploring the potential underlying mechanisms.We also address growing concerns regarding PPI overuse,including its potential effects on cancer therapy efficacy and the risk of drug interactions.Ultimately,this article highlights the urgent need for further research to evaluate the safety and efficacy of PPIs in cancer patients and to better understand their broader implications.

文摘This editorial comments on the article by Qu et al in a recent edition of World Journal of Gastrointestinal Oncology,focusing on the importance of early diagnosis in managing esophageal cancer and strategies for achieving“early detection”.The five-year age-standardized net survival for esophageal cancer patients falls short of expectations.Early detection and accurate diagnosis are critical strategies for improving the treatment outcomes of esophageal cancer.While advancements in endoscopic technology have been significant,there seems to be an excessive emphasis on the latest high-end endoscopic devices and various endoscopic resection techniques.Therefore,it is imperative to redirect focus towards proactive early detection strategies for esophageal cancer,investigate the most cost-effective screening methods suitable for different regions,and persistently explore practical solutions to improve the five-year survival rate of patients with esophageal cancer.
文摘Robotic surgery systems,as emerging minimally invasive approaches,have been increasingly applied for the treatment of esophageal cancer because they provide a high-definition three-dimensional surgical view and mechanical rotating arms that surpass the limitations of human hands,greatly enhancing the accuracy and flexibility of surgical methods.Robot-assisted McKeown esophagectomy(RAME),a common type of robotic esophagectomy,has been gradually implemented with the aim of reducing postoperative complications,improving postoperative recovery and achieving better long-term survival.Multiple centers worldwide have reported and summarized their experiences with the RAME,and some have also discussed and analyzed its perioperative effects and survival prognosis compared with those of video-assisted minimally invasive esophagectomy.Compared to traditional surgery,the RAME has significant advantages in terms of lymph node dissection although there seems to be no difference in overall survival or disease-free survival.With the continuous advancement of technology and the development of robotic technology,further development and innovation are expected in the RAME field.This review elaborates on the prospects of the application and advancement of the RAME to provide a useful reference for clinical practice.
文摘BACKGROUND Esophageal cancer is one of the most common malignant tumors.The three-dimensional quality structure model is a quality assessment theory that includes three dimensions:Structure,process,and results.AIM To investigate the effects of nursing interventions with three-dimensional quality assessment on the efficacy and disease management ability of patients undergoing esophageal cancer surgery.METHODS In this prospective study,the control group received routine nursing,and the intervention group additionally received a three-dimensional quality assessment intervention based on the above routine care.Self-efficacy and patient disease management abilities were evaluated using the General Self-Efficacy Scale(GSES)and Exercise of Self-Care Agency scale,respectively.IBM SPSS Statistics for Windows,version 17.0,was used for the data processing.RESULTS This study recruited 112 patients who were assigned to the control and experi-mental groups(n=56 per group).Before the intervention,there was no significant difference in GSES scores between the two groups(P>0.05).After the inter-vention,the GSES scores of both groups increased,with the experimental group showing higher values(P<0.05).At the time of discharge and three months after discharge,the scores for positive attitudes,self-stress reduction,and total score of health promotion in the experimental group were higher than those in the control group(P<0.05).CONCLUSION The implementation of a three-dimensional quality structure model for postoperative patients with esophageal cancer can effectively improve their self-management ability and self-efficacy of postoperative patients.
文摘Objective:Esophageal cancer(EC)ranks eighth among cancers in cancer-related deaths globally,and~44%of new cases occur in China.We sought to describe the clinical characteristics and treatment landscape of EC in China before the approval of immunotherapy in 2020.Methods:CHANNEL was a large,retrospective study using patient-level data from 14 hospitals/cancer centers across China,including adults initiating therapy for newly diagnosed EC(January to December 2018).Demographics,clinicopathologic characteristics,and treatment patterns over 6 months were descriptively summarized.Results:Of 3,493 patients,75.7%were men,the mean age was 64.1 years,and 75.0%had no family history of cancer.Most(92.8%)had squamous cell carcinoma,with a primary lesion in the middle esophagus(56.4%).Among patients with resectable EC,92.9%received initial surgery,and 7.1%received neoadjuvant therapy,primarily chemotherapy(85.5%platinum-taxane).Among patients with unresectable early or locally advanced EC,50.8%and 49.2%received palliative and radical therapy,respectively,as the initial treatment,primarily chemotherapy(66.5%platinum-taxane)and chemoradiotherapy(50.8%platinum-taxane),respectively.Adjuvant therapy was administered to 22.9%of patients undergoing initial surgery,and 2.4%receiving neoadjuvant therapy and surgery.Among patients with advanced EC,84.6%received systemic therapy as an initial treatment,primarily chemotherapy(61.5%platinum-taxane).Conclusions:Before the approval of immunotherapy in China,most patients with resectable early or locally advanced EC underwent radical surgery without preoperative treatment,whereas most patients with advanced EC received platinum-taxane chemotherapy.These findings highlight the need for novel EC treatments before immunotherapy was introduced,and provide a baseline for evaluating the benefits of immunotherapy,now that this treatment is widely used in this setting.
文摘Aim: This study evaluates the impact of Enhanced Recovery After Surgery (ERAS) nursing on postoperative complications and quality of life in patients undergoing robot-assisted minimally invasive esophagectomy (RAMIE). Methods: A total of 150 patients who underwent RAMIE from January 2020 to January 2022 at our hospital were randomly assigned to either the observation group or the control group, with 75 patients in each. The control group received standard perioperative management and nursing care, while the observation group was treated with ERAS nursing strategies. Interventions continued until discharge, and outcomes such as postoperative complications, quality of life, and nutritional status were compared between the groups. Results: The observation group exhibited a significantly lower incidence of postoperative adverse reactions compared to the control group (P ionally, all dimension scores of the Short-Form 36 Health Survey (SF-36), including the total score, were higher in the observation group (P < 0.05). Furthermore, the Nutritional Risk Screening (NRS) scores for impaired nutritional status and disease severity, along with the total NRS score, were significantly lower in the observation group compared to the control group (P Conclusion: Implementing ERAS nursing in the perioperative care of patients undergoing RAMIE is associated with reduced postoperative complications and enhanced postoperative quality of life and nutritional status. .
文摘In this editorial we comment on the article published by Ning et al,“Role of exosomes in metastasis and therapeutic resistance in esophageal cancer”.Esophageal cancer(EC)represents a significant global health concern,being the seventh most common and sixth in terms of mortality worldwide.Despite the advances in therapeutic modalities,the management of patients with EC remains challenging,with a 5-year survival rate of only 25%and a limited eligibility for curative surgery due to its late diagnosis.Conventional screening methods are impractical for the early detection of EC,given their either invasive or insensitive nature.The advent of liquid biopsy,with a focus on circulating tumor cells,circulating tumor DNA,and exosomes,heralds a non-invasive avenue for cancer detection.Exosomes,small vesicles involved in intercellular communication,are highlighted as potential biomarkers for EC diagnosis and prognosis.Along with a diverse cargo encompassing various types of RNA,DNA molecules,proteins,and metabolites,exosomes emerge as key players in tumorigenesis,tumor development,and metastasis.Their significance extends to carrying distinctive biomarkers,including microRNAs(miRNAs),long non-coding RNAs,and circular RNAs,underscoring their potential diagnostic and prognostic value.Furthermore,exosomes may be utilized for therapeutic purposes in the context of EC treatment,serving as efficient delivery vehicles for therapeutic agents such as chemotherapeutic medicines and miRNAs.In this editorial we delve into the applications of exosomes for the early detection and treatment of EC,as well as the future perspectives.
