Imune Cell Infiltration Hierarchical Clustering Based Molecular Subtyping for Predicting Prognosis and Immunotherapy Efficacy in Esophageal Squamous Cell CarcinomaAbstract:Objective To construct an immune molecule-based prognostic model for predicting esophageal squamous cell carcinoma(ESCC)prognosis and immunotherapy efficacy based on estimates of the types and characteristics of immune infiltrating cells within the tumor microenvironment(TME)in ESCC.construct an immune molecule-based prognostic model for predicting ESCC prognosis and immunotherapy efficacy.Methods The mRNA transcriptomic data of 179 ESCC samples(GSE53625)were retrieved from the Gene Expression Omnibus(GEO)databases.The proportions of immune cell infiltration in 179 ESCC tissue were calculated using the CIBERSORT algorithm;unsupervised hierarchical clustering was performed based on 22 immune infiltrating cell levels to identify key immune molecules associated with prognosis in different IIC groups.Based on the differential expression between IIC groups,a molecular prognostic TPM model was constructed,and the prognostic risk values(RS)of TPMpatients in each group were calculated.The predictive effect of TPMmodel on immune therapy response was validated further through multiple datasets(GSE 135222,GSE91061,IMvigor210).Kaplan-Meier curves were used to plot survival curves,and the Log-rank test was employed to assess differences in survival times between groups,with a test level of α=0.05.Results Among 179 ESCC samples,101 samples showed significantly infiltrated immune cells(P<0.05).Through unsupervised hierarchical clustering analysis,101 patients were divided into IIC-1,IIC-2,and IIC-3 groups.Among them,the overall survival time of patients in the IIC-3 group was significantly shorter than that of patients in the IIC-2 and IIC-1 groups at 5 years.Further analysis identified differentially expressed immune related molecules in the IIC 3 group,including CD8A,CD79A,and CXCL9,to construct a TPM model.Among the 101 patients,the high-risk RS group(32 cases)had the shortest overall survival time;the 26 independently validated ESCC samples showed a significant negative correlation between RS and patient prognosis(P=0.002).Conclusion The immune infiltrating cells within the ESCC tumor microenvironment exhibit heterogeneity,represented by CD8A,CD79A,and CXCL9,dictate anti-tumor immunity of ESCC patients,and are correlated with long-term outcome of ESCC patients,which could provide guidance for individualized immunotherapy of ESCC patients.
Research Progress of Combined Immunotherapy Model for Esophageal CancerAbstract:Esophageal cancer(EC)is one of the most common malignant tumors.The number of new cases and deaths in China accounts for 53.7%and 55.35%of the total global figure respectively.As a region with high incidence of esophageal cancer,the prognosis of patients with esophageal cancer is currently poor,and the treatment status is still unsatisfactory.In recent years,immunotherapy,as a new treatment for solid tumors,has been successfully applied in clinical settings,bringing new hope to cancer patients.Immunotherapy for esophageal cancer includes immune checkpoint inhibitors(ICIs),tumor vaccines,and adoptive cell therapy.Among them,immune checkpoint inhibitors release immune cells to fight cancer by blocking the pathways that tumor cells use to shut down anti-tumor immune responses.The programmed cell death protein 1(PD-1)and its ligands are the main drugs that mediate tumor immunosuppression and have shown promising therapeutic effects in combination therapy.This article provides a comprehensive review of the research progress of immunotherapy combined with chemotherapy,targeted therapy,radiotherapy,and surgery in esophageal cancer.
Advances in Neoadjuvant Chemotherapy Combined with Immunotherapy in Adenocarcinoma of Esophagogastric JunctionAbstract:Adenocarcinoma of esophagogastric junction(AEG)is a malignant tumour that originates at the junction of the oesophagus and the stomach.The incidence of AEG has been increasing globally,and it is challenging to diagnose at an early stage,with many patients presenting with locally advanced or metastatic tumours when diagnosed.Neoadjuvant chemotherapy is a standard treatment that can reduce tumour size and improve R0 resection and long-term survival rates.However,the efficacy of chemotherapy is limited,and the toxic side effects are significant.In recent years,immunotherapy has emerged as a prominent area of research in the context of preoperative treatment for AEG,particularly in patients with locally advanced AEG.The combination of immune checkpoint inhibitors and chemotherapy has demonstrated considerable therapeutic potential in this setting.This combination regimen has been demonstrated to increase the rate of pathologic complete response(pCR),while also enhancing the immune response and improving the survival prognosis of patients.Nevertheless,further research is required to address individual differences and immune-related adverse events(irAEs).This review focus on the research progress of neoadjuvant chemotherapy combined with immunotherapy in AEG in recent years,and to evaluate the efficacy and safety of this approach and explore the possibility of individualised treatment.

Diagnosis and Treatment Guidelines for Infectious Esophageal CancerAbstract:China is among the global regions with a high burden of esophageal cancer.The incidence and mortality of esophageal cancer in China exhibited a rising trend prior to 2010,followed by a substantial and sustained decline in the subsequent period.Emerging breakthroughs in etiological studies,particularly the definitive identification of oral microorganisms(e.g.,Porphyromonas gingivalis)as critical pathogenic contributors to esophageal carcinogenesis,have established a solid theoretical foundation for the optimization of prevention,treatment and rehabilitation strategies for esophageal cancer patients.Oral hygiene,as a key indicator for high-risk population screening,has been incorporated into the Plan for Esophageal Cancer Screening and Early Diagnosis and Treatment issued by the National Health Commission.To standardize the whole-course oral hygiene management throughout the full workflow of esophageal cancer prevention,screening,diagnosis,treatment and rehabilitation,the Committee of Infectious Tumors of the China Anti-Cancer Association assembled a panel of domestic multidisciplinary experts.Following multiple rounds of in-depth deliberation and iterative revision,this guideline was formulated based on a systematic review of the latest domestic and international evidence,with full consideration of the current status and practical demands of clinical practice in China.
Advantages of Ultrasound-Guided Subcostal Transversus Abdominis Plane Block Combined with Rectus Sheath Block in Thoracoscopic-Laparoscopic EsophagectomyAbstract:Objective To investigate the analgesic efficacy of ultrasound-assisted subcostal transversus abdominis plane block(OTAPB)combined with rectus sheath block(RSB)for postoperative pain management in patients undergoing thoracoscopic-laparoscopic esophagectomy of esophageal cancer(EC).Methods 80 patients scheduled for elective thoracoscopic and laparoscopic esophagectomy at Anyang Cancer Hospital between November 2023 and May 2024 were prospectively randomized into two groups:the TP group(ultrasound-guided thoracic paravertebral block combined with general anesthesia,n=40)and the OR group(ultrasound-guided oblique subcostal transversus abdominis plane block combined with rectus sheath block and general anesthesia,n=40).Both groups underwent nerve block procedures after anesthesia induction,using 40 mL of 0.25%ropivacaine.Postoperatively,patient-controlled intravenous analgesia was provided to all patients.Primary outcomes included:visual analogue scale(VAS)scores at rest and during cough at 2 h,4 h,8 h,12 h,18 h,and 24 h postoperatively;number of PCA presses and rescue analgesia requirements within 24 h;and duration of nerve block procedure.Secondary outcomes included:MAP,HR,and PPI at predefined timepoints,surgical site,duration,intraoperative opioid and vasopressor use,and complications related to nerve block(hematoma,local anesthetic toxicity,infection)within 24 h postoperatively.Results Compared with the TP group,the OR group had significantly fewer PCA presses(P<0.05)and lower rescue analgesia requirements(P<0.05)within 24 h postoperatively.Additionally,the OR group demonstrated lower VAS scores at rest(4 h,8 h,12 h,18 h)and during cough(2 h,4 h,8 h,12 h,18 h)(P<0.05).The duration of the nerve block procedure was also shorter in the OR group(P<0.05).Conclusion Ultrasound-guided OTAPB+RSB is a more convenient technique that effectively manages postoperative abdominal incisional pain in patients undergoing thoracoscopic and laparoscopic esophagectomy,reducing postoperative pain scores.
Mechanism of FSP1-Mediated Ferroptosis Resistance in 5-Fluorouracil Chemoresistance of Esophageal Carcinoma and the Chemosensitization Effect of iFSP1Abstract:Objective To investigate the expression of ferroptosis suppressor protein 1(FSP1)in esophageal cancer,its relationship with prognosis,the mechanism by which it mediates 5-fluorouracil(5-FU)chemotherapy resistance,and the chemosensitizing effect of the FSP1 inhibitor(iFSP1).Methods The Cancer Genome Atlas(TCGA)was used to analyze FSP1 expression and its prognostic significance in esophageal cancer.Immunohistochemistry was performed to detect FSP1 expression in esophageal cancer and adjacent non-cancerous tissues.A 5-FU resistant esophageal cancer cell line was established using the concentration gradient method.Western blot was used to detect FSP1 protein expression in the resistant cells.Cell immunofluorescence,flow cytometry,CCK-8 assay,and colony formation assay were employed to evaluate the reversal effect of iFSP1 on chemoresistance in esophageal cancer.Results FSP1 was highly expressed in esophageal cancer tissues and was associated with poor prognosis.FSP1 protein expression was increased in 5-FU resistant esophageal cancer cells.High FSP1 expression was closely correlated with resistance to 5-FU chemotherapy.Treatment with a specific FSP1 inhibitor enhanced ferroptosis in tumor cells and increased the sensitivity of esophageal cancer cells to 5-FU.Conclusion FSP1 mediates 5-FU chemotherapy resistance in esophageal cancer by inhibiting ferroptosis in tumor cells.Targeting FSP1 may reverse chemotherapy resistance in esophageal cancer.
Study on M2 Macrophages and Their Associated Gene FOLR2 in Esophageal Squamous Cell CarcinomaAbstract:Objective To investigate the infiltration or expression levels of M2 macrophages and their related key genes in esophageal squamous cell carcinoma(ESCC),and to assess their impact on the prognosis of ESCC patients.Methods The ESCC gene expression matrix was obtained from the TCGA database.Basingon Rstudio,the infiltration level of M2 macrophages in ESCC tissues was assessed with the immune infiltration CIBERSORT package,and the key genes related to M2 macrophages were identified through difference analysis with the Limma package.Finally,the influence of M2 macrophages infiltration level and related keys on the prognosis of ESCC patients was evaluated by survⅣal package.Results Studies have shown that there are differences in the infiltration levels of 22 types of immune cells in ESCC tissue,among which M2 macrophages have relatively higher infiltration levels and are significantly correlated with poorer survival rates.FOLR2,as a key gene,is highly expressed in ESCC tissues and is closely related to pathological grading,clinical staging,TP53 mutation and poor prognosis.Single-cell data analysis suggests that FOLR2 is mainly expressed in macrophages.Conclusion M2 macrophages play an important role in ESCC studies,and FOLR2 can be used as an effective biomarker and potential therapeutic target for ESCC.

Retrospective Study on Pulmonary Infection after Thoracoscopic Assisted Radical Resection of Esophageal Cancer through Right Thoracic PathwayAbstract:Objective To identify the risk factors associated with pulmonary infections following thoracoscopic-assisted radical esophagectomy via the right thoracic approach.Methods Clinical data were collected from patients who underwent thoracoscopic-assisted radical esophagectomy using a right thoracic approach in our hospital,between February 2023 and April 2024 and were categorized into two groups based on the presence or absence of postoperative pulmonary infections.Methods Univariate and multivariate regression analyses were employed to identify potential risk factors for postoperative pulmonary infections,and the underlying pathological mechanisms were explored.Results A total of 86 patients with esophageal cancer were included,of whom 18(20.9%)developed postoperative pulmonary infections.Univariate regression analysis indicated that age≥60 years,abnormal body mass index(BMI),a history of smoking≥600 cigarettes annually,pre-existing lung disease,diabetes mellitus,operative time≥4 h,and preoperative serum albumin levels<40 g·L-1 were significantly associated with an increased risk of postoperative pulmonary infections(P<0.05),and that prolonged operative time,pre-existing lung disease,and diabetes mellitus were independent risk factors for postoperative pulmonary infections(P<0.05).Conclusion The risk of lung infection in patients with prolonged operation time,basic lung diseases and diabetes after right thoracic approach thoracoscopic assisted radical esophagectomy for esophageal cancer is significantly increased.Targeted preventive measures can help reduce the incidence of postoperative pulmonary infections.
Current Situation and Progress of Timing of Surgery after Neoadjuvant Therapy for Esophageal CancerAbstract:Followed by neoadjuvant therapy,patients with locally advanced esophageal cancer will un-dergo radical surgical resection after a time interval,which is mainly to allow the tumor regression within it,to increase the R0 resection rate,pathological complete response rate and long-term survival.Secondly,a certain interval of time can maximize the recovery from toxicities caused by preoperative therapy and reduce the incidence of perioperative complications.However,a long interval before operation will increase the risk of tumor cell proliferation and metastasis,and the continuous fibrosis after tumor regression will increase the difficulty of surgery.The optimal timing of surgery is inconclusive.This article reviews and analyzes relevant literature and research,and elaborates on the selection of surgical timing after neoadjuvant therapy,hoping to provide reference for clinical work and further research,thereby improving the survival benefits of esophageal cancer patients.
