Meta-Analysis of the Efficacy and Safety of Pembrolizumab in the Treatment of Advanced Gastric Cancer and Gastroesophageal Junction Cancer.	INTRODUCTION: Pembrolizumab has been approved for the first-line treatment of patients with advanced gastric cancer (GC) and gastroesophageal junction (GEJ) cancer. However, the results of several clinical trials are not entirely consistent, and the dominant population of first-line immunotherapy for advanced GC/GEJ still needs to be precisely determined. PURPOSE: The aim of this meta-analysis was to assess the efficacy and safety of pembrolizumab in the treatment of advanced GC/GEJ. METHODS: We conducted computerized searches across multiple databases, including PubMed, Cochrane Library, Web of Science, and Embase. We established the inclusion criteria to comprise randomized clinical trials examining the efficacy of pembrolizumab in late-stage GC/GCJ cancer. We conducted a meta-analysis of outcome measures using STATA 14.0 software. RESULTS: A total of six studies involving 1,448 cases were included in this analysis. The results of the meta-analysis indicate that, when compared to chemotherapy, patients in the pembrolizumab group experienced a significant reduction in the risk of mortality in terms of overall survival (OS) (hazard ratio [HR] = 0.72, 95% confidence interval [CI]: 0.65-0.79, p < 0.01). In terms of progression-free survival (PFS), pembrolizumab was associated with a similar PFS as compared to chemotherapy (HR = 0.88, 95% CI: 0.73-1.07, p = 0.206). Subgroup analyses based on PD-L1 expression levels indicated a significantly longer PFS with pembrolizumab in subgroups of patients with PD-L1 CPS ≥10 but not in those with PD-L1 CPS ≥1 and PD-L1 CPS ≥5. Subgroup analyses based on distinct geographical regions revealed a comparable effect of PFS in patients residing in Asia or the USA Subgroup analysis based on tumor sites consistently demonstrated a similar effect of PFS in patients with EC/GEJ tumors and GC patients. CONCLUSION: Our findings demonstrated that pembrolizumab led to a significant extension in OS and objective response rate, along with a favorable tolerability profile compared to chemotherapy. Furthermore, the observed survival benefits were particularly pronounced in subgroup patients with a CPS of ≥10. Given the potential limitations inherent in our study, it is imperative to underscore the necessity for further large-scale RCTs to corroborate our results.	esophagus
A comparative assessment of ACS NSQIP-predicted and actual surgical risk outcomes of robotic transhiatal esophagectomy for esophageal adenocarcinoma resection at a high volume institution.	Esophageal adenocarcinoma incidence is increasing in Western nations. There has been a shift toward minimally invasive approaches for transhiatal esophagectomy (THE). This study compares the outcomes of robotic THE for esophageal adenocarcinoma resection at our institution with the predicted metrics from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). With Institutional Review Board (IRB) approval, we prospectively followed 83 patients who underwent robotic THE from 2012 to 2023. Predicted outcomes were determined using the ACS NSQIP Surgical Risk Calculator. Our outcomes were compared with these predicted outcomes and with general outcomes for transhiatal esophagectomy reported in ACS NSQIP, which includes a mix of surgical approaches. The median age of patients was 70 years, with a body mass index (BMI) of 26.4 kg/m(2) and a male prevalence of 82%. The median length of stay was 7 days. The rates of any complications and in-hospital mortality were 16% and 5%, respectively. Seven patients (8%) were readmitted within a 30-day postoperative window. The median survival is anticipated to surpass 95 months. Our outcomes were generally aligned with or surpassed the predicted ACS NSQIP metrics. The extended median survival of over 95 months highlights the potential effectiveness of robotic THE in the resection of esophageal adenocarcinoma. Further exploration into its long-term survival benefits and outcomes is warranted, along with studies that provide a more direct comparison between robotic and other surgical approaches.	esophagus
Zolbetuximab: First Approval.	Zolbetuximab (VYLOY™), a recombinant, chimeric, anti-claudin 18.2 (CLDN18.2) monoclonal antibody (mAb), is being developed by Astellas Pharma Inc. for the treatment of patients with HER2-negative (HER2(-)), CLDN18.2-positive (CLDN18.2(+)) advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma and CLDN18.2(+) advanced pancreatic adenocarcinoma. In March 2024, zolbetuximab was approved in Japan for the treatment of patients with HER2(-), CLDN18.2(+) unresectable, advanced/recurrent gastric cancer (the gastric cancer indication includes GEJ cancer). Zolbetuximab is also undergoing regulatory review for HER2(-), CLDN18.2(+) advanced gastric or GEJ adenocarcinoma in the USA, the EU, China, Australia and several other countries. This article summarizes the milestones in the development of zolbetuximab leading to this first approval for the treatment of patients with CLDN18.2(+) gastrointestinal malignancies.	esophagus
Tracheal repair with sternocleidomastoid flap in mediastinoscopic surgery for esophageal cancer.	Tracheal injury during mediastinoscopic esophagectomy is a life-threatening complication that is challenging to manage. However, no precise treatment has been defined. An 80-year-old male patient with upper esophageal cancer underwent a mediastinoscopic esophagectomy and gastric tube reconstruction through the posterior mediastinal route. When the esophagus was separated from the trachea using a bipolar vessel sealing system, the left side of the membranous trachea incurred a 3-cm defect 7 cm below the sternal notch. We successfully repaired the tracheal injury not by directly suturing the defect but by reinforcing it with a pedicle sternocleidomastoid flap. The gastric tube was placed over the tracheal repair for esophageal reconstruction via a posterior mediastinal route. As a result, the patient recovered well and was discharged. A sternocleidomastoid flap might be another surgical option for reinforcement flaps in tracheal injuries.	esophagus
The Novel-B-Cell-Related Gene Signature Predicts the Prognosis and Immune Status of Patients with Esophageal Carcinoma.	BACKGROUND: The current understanding of the prognostic significance of B cells and their role in the tumor microenvironment (TME) in esophageal carcinoma (ESCA) is limited. METHODS: We conducted a screening for B-cell-related genes through the analysis of single-cell transcriptome data. Subsequently, we developed a B-cell-related gene signature (BRGrisk) using LASSO regression analysis. Patients from The Cancer Genome Atlas cohort were divided into a training cohort and a test cohort. Patients were categorized into high- and low-risk groups based on their median BRGrisk scores. The overall survival was assessed using the Kaplan-Meier method, and a nomogram based on BRGrisk was constructed. Immune infiltration profiles between the risk groups were also compared. RESULTS: The BRGrisk prognostic model indicated significantly worse outcomes for patients with high BRGrisk scores (p < 0.001). The BRGrisk-based nomogram exhibited good prognostic performance. Analysis of immune infiltration revealed that patients in the high-BRGrisk group had notably higher levels of immune cell infiltration and were more likely to be in an immunoresponsive state. Enrichment analysis showed a strong correlation between the prognostic gene signature and cancer-related pathways. IC50 results indicated that patients in the low-BRGrisk group were more responsive to common drugs compared to those in the high-BRGrisk group. CONCLUSIONS: This study presents a novel BRGrisk that can be used to stratify the prognosis of ESCA patients and may offer guidance for personalized treatment strategies aimed at improving prognosis.	esophagus
Disease-specific health-related quality of life trajectories up to 15 years after curative treatment for esophageal cancer-a prospective cohort study.	BACKGROUND: The presence of distinct long-term disease-specific HRQL trajectories after curative treatment for esophageal cancer and factors associated with such trajectories are unclear. MATERIALS AND METHODS: This population-based and longitudinal cohort study included 425 esophageal cancer patients who underwent curative treatment, including esophagectomy, in Sweden in 2001-2005 and were followed up until 2020, that is, 15-year follow-up. The outcomes were 10 disease-specific HRQL symptoms, measured by the well-validated EORTC QLQ-OES18 questionnaire at 6 months (n = 402 patients), and 3 (n = 178), 5 (n = 141), 10 (n = 92), and 15 years (n = 52) after treatment. HRQL symptoms were examined for distinct trajectories by growth mixture models. Weighted logistic regression models provided odds ratios (OR) with 95% confidence intervals (95% CI) for nine factors in relation to HRQL trajectories: age, sex, education, proxy baseline HRQL, comorbidity, tumor histology, chemo(radio)therapy, pathological tumor stage, and postoperative complications. RESULTS: Distinct HRQL trajectories were identified for each of the 10 disease-specific symptoms. HRQL trajectories with more symptoms tended to persist or alleviate over time, while trajectories with fewer symptoms were more stable. Eating difficulty had three trajectories: persistently less, persistently moderate, and persistently more symptoms. The OR of having a persistently more eating difficulty trajectory was decreased for adenocarcinoma histology (OR = 0.44, 95% CI 0.21-0.95), and increased for pathological tumor stage III-IV (OR = 2.19, 95% CI 0.99-4.82) and 30-day postoperative complications (OR = 2.54, 95% CI 1.26-5.12). CONCLUSION: Distinct trajectories with long-term persistent or deteriorating disease-specific HRQL symptoms were identified after esophageal cancer treatment. Tumor histology, tumor stage, and postoperative complications may facilitate detection of high-risk patients for unwanted trajectories.	esophagus
Diffuse-Type Histology Is Prognostic for All Siewert Types of Gastroesophageal Adenocarcinoma.	PURPOSE: The optimal treatment for gastroesophageal junction adenocarcinoma (GEJA) remains controversial. We evaluated the treatment patterns and outcomes of patients with locally advanced GEJA according to the histological type. MATERIALS AND METHODS: We conducted a single-institution retrospective cohort study of patients with locally advanced GEJA who underwent curative-intent surgical resection between 2010 and 2020. Perioperative therapies as well as clinicopathologic, surgical, and survival data were collected. The results of endoscopy and histopathological examinations were assessed for Siewert and Lauren classifications. RESULTS: Among the 58 patients included in this study, 44 (76%) were clinical stage III, and all received neoadjuvant therapy (72% chemoradiation, 41% chemotherapy, 14% both chemoradiation and chemotherapy). Tumor locations were evenly distributed by Siewert Classification (33% Siewert-I, 40% Siewert-II, and 28% Siewert-III). Esophagogastrectomy (EG) was performed for 47 (81%) patients and total gastrectomy (TG) for 11 (19%) patients. All TG patients received D2 lymphadenectomy compared to 10 (21%) EG patients. Histopathological examination showed the presence of 64% intestinal-type and 36% diffuse-type histology. The frequencies of diffuse-type histology were similar among Siewert groups (37% Siewert-I, 36% Siewert-II, and 33% Siewert-III). Regardless of Siewert type and compared to intestinal-type, diffuse histology was associated with increased intraabdominal recurrence rates (P=0.03) and decreased overall survival (hazard ratio, 2.33; P=0.02). With a median follow-up of 31.2 months, 29 (50%) patients had a recurrence, and the median overall survival was 50.5 months. CONCLUSIONS: Present in equal proportions among Siewert types of esophageal and gastric cancer, a diffuse-type histology was associated with high intraabdominal recurrence rates and poor survival. Histopathological evaluation should be considered in addition to anatomic location in the determination of multimodal GEJA treatment strategies.	esophagus
Genomic characteristics and evolution of Multicentric Esophageal and gastric Cardiac Cancer.	BACKGROUND: Esophageal carcinoma (EC) and gastric cardiac adenocarcinoma (GCA) have high incidence rates in the Chaoshan region of South China. Multifocal esophageal and cardiac cancer (MECC) is commonly observed in this region in clinical practice. However, the genomic characteristics of MECC remains unclear. MATERIALS AND METHODS: In this study, a total of 2123 clinical samples of EC and GCA were analyzed to determine the frequency of multifocal tumors, as well as their occurrence sites and pathological types. Cox proportional hazards regression was used to model the relationship between age, sex, and tumor state concerning survival in our analysis of the cohort of 541 patients with available follow-up data. We performed whole-genome sequencing on 20 tumor foci and 10 normal samples from 10 MECC patients to infer clonal structure on 6 MECC patients to explore genome characteristics. RESULT: The MECC rate of EC and GCA was 5.65% (121 of 2123). Age and sex were potential factors that may influence the risk of MECC (p < 0.001). Furthermore, MECC patients showed worse survival compared with single tumor patients. We found that 12 foci from 6 patients were multicentric origin model (MC), which exhibited significant heterogeneity of variations in paired foci and had an increased number of germline mutations in immune genes compared to metastatic model. In MC cases, different lesions in the same patient were driven by distinct mutation and copy number variation (CNV) events. Although TP53 and other driver mutation genes have a high frequency in the samples, their mutation sites show significant heterogeneity in paired tumor specimens. On the other hand, CNV genes exhibited higher concordance in paired samples, especially in the amplification of oncogenes and the deletion of tumor suppressor genes. CONCLUSIONS: The extent of inter-tumor heterogeneity suggests both monoclonal and polyclonal origins of MECC, which could provide insight into the genome diversity of MECC and guide clinical implementation.	esophagus
The Tissue Systems Pathology Test Objectively Risk-Stratifies Patients With Barrett's Esophagus: Results From a Multicenter US Clinical Experience Study.	BACKGROUND: Barrett's esophagus (BE) is a diagnosis of esophageal intestinal metaplasia, which can progress to esophageal adenocarcinoma (EAC), and guidelines recommend endoscopic surveillance for early detection and treatment of EAC. However, current practices have limited effectiveness in risk-stratifying patients with BE. AIM: This study aimed to evaluate use of the TSP-9 test in risk-stratifying clinically relevant subsets of patients with BE in clinical practice. METHODS: TSP-9 results for tests ordered by 891 physicians for 8080 patients with BE with clinicopathologic data were evaluated. Orders were from nonacademic (94.3%) and academic (5.7%) settings for nondysplastic BE (NDBE; n=7586; 93.9%), indefinite for dysplasia (IND, n=312, 3.9%), and low-grade dysplasia (LGD, n=182, 2.3%). RESULTS: The TSP-9 test scored 83.2% of patients with low risk, 10.6% intermediate risk, and 6.2% high risk, respectively, for progression to HGD/EAC within 5 years. TSP-9 provided significant risk-stratification independently of clinicopathologic features, within NDBE, IND, and LGD subsets, male and female, and short- and long-segment subsets of patients. TSP-9 identified 15.3% of patients with NDBE as intermediate/high-risk for progression, which was 6.4 times more than patients with a pathology diagnosis of LGD. Patients with NDBE who scored intermediate or high risk had a predicted 5-year progression risk of 8.1% and 15.3%, respectively, which are similar to and higher than published progression rates in patients with BE with confirmed LGD. CONCLUSIONS: The TSP-9 test identified a high-risk subset of patients with NDBE who were predicted to progress at a higher rate than confirmed LGD, enabling early detection of patients requiring management escalation to reduce the incidence of EAC. TSP-9 scored the majority of patients with NDBE as low risk, providing support to adhere to 3- to 5-year surveillance per guidelines.	esophagus
Suppressing SENP1 inhibits esophageal squamous carcinoma cell growth via SIRT6 SUMOylation.	PURPOSE: Esophageal squamous cell carcinoma (ESCC) is a prevalent tumor in the gastrointestinal tract, but our understanding of the molecular mechanisms underlying ESCC remains incomplete. Existing studies indicate that SUMO specific peptidase 1 (SENP1) plays a crucial role in the development and progression of various malignant tumors through diverse molecular mechanisms. However, the functional mechanism and clinical implications of SENP1 in the progression of ESCC remain unclear. METHODS: Bulk RNA-Sequencing (RNA-seq) was used to compare potential genes in the esophageal tissues of mice with ESCC to the control group. The up-regulated SENP1 was selected. The protein level of SENP1 in ESCC patient samples was analyzed by immunohistochemistry and western blot. The potential prognostic value of SENP1 on overall survival of ESCC patients was examined using tissue microarray analysis and the Kaplan-Meier method. The biological function was confirmed through in vitro and in vivo knockdown approaches of SENP1. The role of SENP1 in cell cycle progression and apoptosis of ESCC cells was analyzed by flow cytometry and western blot. The downstream signaling pathways regulated by SENP1 were investigated via using RNA-Seq. SENP1-associated proteins were identified through immunoprecipitation. Overexpression of Sirtuin 6 (SIRT6) wildtype and mutant was performed to investigate the regulatory role of SENP1 in ESCC progression in vitro. RESULTS: Our study discovered that SENP1 was upregulated in ESCC tissues and served as a novel prognostic factor. Moreover, SENP1 enhanced cell proliferation and migration of ESCC cell lines in vitro, as well as promoted tumor growth in vivo. Thymidine kinase 1 (TK1), Geminin (GMNN), cyclin dependent kinase 1(CDK1), and cyclin A2 (CCNA2) were identified as downstream genes of SENP1. Mechanistically, SENP1 deSUMOylated SIRT6 and subsequently inhibited SIRT6-mediated histone 3 lysine 56 (H3K56) deacetylation on those downstream genes. SIRT6 SUMOylation mutant (4KR) rescued the growth inhibition upon SENP1 depletion. CONCLUSIONS: SENP1 promotes the malignant progression of ESCC by inhibiting the deacetylase activity of SIRT6 pathway through deSUMOylation. Our findings suggest that SENP1 may serve as a valuable biomarker for prognosis and a target for therapeutic intervention in ESCC.	esophagus
Prognostic Impact of Inflammation-Based Factors in Patients with Esophageal Squamous Cell Carcinoma Achieving Pathological Complete Response After Neoadjuvant Chemoradiotherapy Followed by Surgery.	BACKGROUND: Patients achieving pathological complete response (pCR) post-neoadjuvant chemoradiotherapy (nCRT) and surgery for locally advanced esophageal squamous cell carcinoma (ESCC) have a favorable prognosis. However, recurrence occurs in approximately 20-30% of all patients, with few studies evaluating their prognostic factors. We identified these prognostic factors, including inflammation-based markers, in patients with ESCC showing pCR after nCRT and surgery. PATIENTS AND METHODS: Patients with ESCC undergoing esophagectomy post-nCRT (January 2007-August 2017) were studied. Survival analysis evaluated 5-year overall (OS) and recurrence-free survival (RFS). Risk factors, including inflammation factors, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio (PLR), were analyzed using Cox-proportional hazards model. RESULTS: Overall, 123patients participated herein. After a median follow-up duration of 67 months (44-86 months), 17 patients (12.3%) had recurrent disease. The 5-year OS and RFS rates were 71.6% and 68.0%, respectively. In the multivariable analysis, older age (  ≥  60 years) [hazard ratio (HR) 3.228, 95% confidence interval (CI) 1.478-7.048, p = 0.003], higher pretreatment T stage (≥ T3; HR 2.563, 95% CI 1.335-4.922, p = 0.005), nonapplication of induction chemotherapy (HR 2.389, 95% CI 1.184-4.824, p = 0.015), and higher post-nCRT PLR (≥ 184.2; HR 2.896, 95% CI 1.547-5.420, p = 0.001) were poor independent prognostic factors for 5-year RFS. The patient group with three to four identified factors with poor outcomes exhibited a 5-year RFS rate of 46.2%. CONCLUSIONS: Significant prognostic factors include higher post-nCRT PLR, older age, higher clinical T stage, and nonapplication of induction chemotherapy. Identifying higher recurrence risk patients is crucial for tailored follow-up and treatment.	esophagus
Multiple diffusion models for predicting pathologic response of esophageal squamous cell carcinoma to neoadjuvant chemotherapy.	BACKGROUND: To assess the feasibility and diagnostic performance of the fractional order calculus (FROC), continuous-time random-walk (CTRW), diffusion kurtosis imaging (DKI), intravoxel incoherent motion (IVIM), mono-exponential (MEM) and stretched exponential models (SEM) for predicting response to neoadjuvant chemotherapy (NACT) in patients with esophageal squamous cell carcinoma (ESCC). MATERIALS AND METHODS: This study prospectively included consecutive ESCC patients with baseline and follow up MR imaging and pathologically confirmed cT1-4aN + M0 or T3-4aN0M0 and underwent radical resection after neoadjuvant chemotherapy (NACT) between July 2019 and January 2023. Patients were divided into pCR (TRG 0) and non-pCR (TRG1 + 2 + 3) groups according to tumor regression grading (TRG). The Pre-, Post- and Delta-treatment models were built. 18 predictive models were generated according to different feature categories, based on six models by five-fold cross-validation. Areas under the curve (AUCs) of the models were compared by using DeLong method. RESULTS: Overall, 90 patients (71 men, 19 women; mean age, 64 years ± 6 [SD]) received NACT and underwent baseline and Post-NACT esophageal MRI, with 29 patients in the pCR group and 61 patients in the non-pCR group. Among 18 predictive models, The Pre-, Post-, and Delta-CTRW model showed good predictive efficacy (AUC = 0.722, 0.833 and 0.790). Additionally, the Post-FROC model (AUC = 0.907) also exhibited good diagnostic performance. CONCLUSIONS: Our study indicates that the CTRW model, along with the Post-FROC model, holds significant promise for the future of NACT efficacy prediction in ESCC patients.	esophagus
