Tumor-infiltrating lymphocyte signature in epithelial and stromal compartments of an esophageal squamous cell carcinoma acidic microenvironment mediated by MCT4.	Tumor-infiltrating lymphocytes (TILs), including but not limited to neutrophils, M2 macrophages, cytotoxic CD8 T cells and dendritic cells, will play a role in the acidic tumor microenvironment mediated by monocarboxylate transporter 4 (MCT4) in esophageal squamous cell carcinoma (ESCC). However, the roles they play and their significance in ESCC remain less clear. To understand the clinicopathological and prognostic significance of neutrophils, M2 macrophages, CD8 T cells and dendritic cells in the tumor acidic microenvironment mediated by MCT4, we investigated the distribution of these TILs in the epithelial and stromal compartments of ESCC by means of multiplexed immunohistochemistry on a tissue microarray containing 87 paired dots of ESCC and its adjacent normal tissue (ANT) and an additional 6 cases of unpaired ESCC dots. The density of cells stained with MCT4 in the epithelium was significantly associated with overall survival. Dendritic cells stained with S100 in epithelial compartmentalization were found to markedly correlate with clinical stage and tumor invasion depth. No other significant association could be identified in terms of prognostic and clinicopathological significance. The potential correlation between the number of cells stained with MCT4 versus the number of TILs was also explored, showing that only in epithelial cells were there significant and positive correlations identified between the number of cells stained with MCT4 versus the number of neutrophils stained with CD15, M2 macrophages stained with CD163 and CD8 T cells stained by CD8a. However, no significant correlation was found along the stromal line. Together, the data we described here, although somewhat discouraging, showed that in epithelial cells from which ESCC originated, acidicity mediated by MCT4 may be responsible for lactate release and may have an effect on the infiltration of TILs we assessed.	esophagus
Deciphering the Immune Complexity in Esophageal Adenocarcinoma and Pre-Cancerous Lesions With Sequential Multiplex Immunohistochemistry and Sparse Subspace Clustering Approach.	Esophageal adenocarcinoma (EAC) develops from a chronic inflammatory environment across four stages: intestinal metaplasia, known as Barrett's esophagus, low- and high-grade dysplasia, and adenocarcinoma. Although the genomic characteristics of this progression have been well defined via large-scale DNA sequencing, the dynamics of various immune cell subsets and their spatial interactions in their tumor microenvironment remain unclear. Here, we applied a sequential multiplex immunohistochemistry (mIHC) platform with computational image analysis pipelines that allow for the detection of 10 biomarkers in one formalin-fixed paraffin-embedded (FFPE) tissue section. Using this platform and quantitative image analytics, we studied changes in the immune landscape during disease progression based on 40 normal and diseased areas from endoscopic mucosal resection specimens of chemotherapy treatment- naïve patients, including normal esophagus, metaplasia, low- and high-grade dysplasia, and adenocarcinoma. The results revealed a steady increase of FOXP3(+) T regulatory cells and a CD163(+) myelomonocytic cell subset. In parallel to the manual gating strategy applied for cell phenotyping, we also adopted a sparse subspace clustering (SSC) algorithm allowing the automated cell phenotyping of mIHC-based single-cell data. The algorithm successfully identified comparable cell types, along with significantly enriched FOXP3 T regulatory cells and CD163(+) myelomonocytic cells as found in manual gating. In addition, SCC identified a new CSF1R(+)CD1C(+) myeloid lineage, which not only was previously unknown in this disease but also increases with advancing disease stages. This study revealed immune dynamics in EAC progression and highlighted the potential application of a new multiplex imaging platform, combined with computational image analysis on routine clinical FFPE sections, to investigate complex immune populations in tumor ecosystems.	esophagus
Prognostic impact of carcinoembryonic antigen in 1822 surgically treated esophageal squamous cell carcinoma: multi-institutional study of the Japan Esophageal Society.	BACKGROUND: Previous studies have evaluated the clinicopathological significance of carcinoembryonic antigen (CEA) of esophageal cancer in relatively small numbers of patients. Therefore, this study aimed to clarify the prognostic significance of CEA in 1822 patients with esophageal squamous cell carcinoma (SCC). METHODS: Based on the Japanese Esophageal Society nationwide multi-institutional retrospective study, a total of 1,748 surgically treated ESCC from 15 hospitals were enrolled to evaluate prognostic impact of preoperative CEA values. Among them, 605 patients were categorized to up-front surgery group, and 1,217 patients were categorized to neoadjuvant therapy group. The CEA threshold for positivity was 3.7 ng/ml. The clinicopathological and prognostic impact of CEA was evaluated by univariate and multivariate analysis in each treatment modality groups. RESULTS: In total, the CEA positive rate was 25.8% (470/1822). CEA-positive status was significantly associated with distant metastasis (P = 0.004) but not associated with other factors. CEA-positive status was associated with poor overall survival (P < 0.001) in univariate analysis as well as multivariate analysis (P = 0.003). CONCLUSIONS: CEA was an independent prognostic determinant of overall survival in esophageal SCC. Based on the subgroup analysis, regardless of the treatment modality, patients with high pretreatment CEA showed poor overall survival.	esophagus
Longitudinal genomic alternations and clonal dynamics analysis of primary malignant melanoma of the esophagus.	Primary malignant melanoma of the esophagus (PMME) is a rare gastrointestinal melanoma with a high rate of recurrence and metastasis. The standard of care for PMME has not been established yet due to a lack of understanding of its clinical and molecular pathogenesis. Thus, we performed genomic profiling on a recurrent PMME case to seek novel opportunities for the management of this rare disease. Between 2013 and 2016, 6 tissue samples including 3 from the primary tumors, 2 from the relapsed tumors, and 1 from a normal control were collected from a patient diagnosed with PMME and were subjected to whole-exome sequencing to track the dynamic genetic changes. Additionally, we also analyzed a cohort of 398 samples obtained from the TCGA skin cutanesous melanoma (TCGA-SKCM) dataset to assess the frequency and determine the clinical implications of genomic events found in the presented study. ARHGAP35 (p.L1022M) was the only mutation shared across temporal PMME lesions. The PMME samples showed higher levels of genetic instability and intra-tumor heterogeneity. They also shared several concordant copy number variations (CNV). All lesions were concordant with the evolution trajectory, and shrinkage of the founding clone caused the subclonal population to become dominant in PT1c, which was likely the reason behind metastatic seeding. ARHGAP35 mutations were found in 6% of the TCGA-SKCM cohort samples. The presence of the mutations was associated with poor progression-free survival (PFS) by both univariate and multivariate Cox regression analyses. Our study showed that the primary tumor clone disseminates earlier in PMME. This highlights the need to understand the mechanism involved in the early PMME recurrence to optimize treatment.	esophagus
The influence of minimally invasive esophagectomy versus open esophagectomy on postoperative pulmonary function in esophageal cancer patients: a meta-analysis.	OBJECTIVE: To compare the influence of minimally invasive esophagectomy (MIE) and open esophagectomy (OE) on postoperative pulmonary function in patients with esophageal cancer. METHODS: Studies about the influence of MIE and OE on postoperative pulmonary function in esophageal cancer patients were searched from PubMed, EMBASE, the Cochrane Library, CNKI, Chinese Science and Technology Journal Database, CBM, and Wanfang Data from inception to March 18, 2021. Meta-analysis was performed using the RevMan 5.3. RESULTS: This analysis included eight studies, enrolling 264 patients who underwent MIE and 257 patients who underwent OE. The meta-analysis results showed that the MIE group had a higher outcome regarding the percent predicted vital capacity (%VC), forced vital capacity (FVC), forced expiratory volume in 1 s (FEV(1)), and maximum voluntary ventilation (MVV) 1 month after surgery than the OE group. In addition, those who underwent MIE had lower ΔVC%, ΔFVC, and ΔFEV(1) between pre-operation and 1 month after surgery than those who underwent OE. There is no statistical difference between the two groups in ΔMVV. CONCLUSION: Compared with OE, MIE has a more protective effect on postoperative pulmonary function. However, due to the small number of included literature and all cohort studies, this finding needs to be validated with larger samples and higher quality RCT studies.	esophagus
Prevalence and risk factors of barrett's esophagus in lynch syndrome.	Lynch syndrome (LS), the most common hereditary cause of colorectal cancer, predisposes to upper gastrointestinal neoplasia. The prevalence of Barrett's esophagus (BE) is elevated in some hereditary gastrointestinal cancer syndromes but has not been systematically evaluated in LS. We assessed the prevalence of BE, BE-related dysplasia, esophageal adenocarcinoma (EAC), and factors associated with BE in LS. Asymptomatic patients with a germline pathogenic variant (PV) in the DNA mismatch repair (MMR) genes undergoing EGD for LS surveillance were identified from a hereditary colorectal cancer registry. We assessed the prevalence of BE and compared demographic, clinical, and endoscopic factors in LS patients with and without BE by logistic regression analysis. 323 patients were included. 21 patients (6.5%) were diagnosed with BE including 38% of females and 33% without gastroesophageal reflux disease (GERD). Dysplasia was diagnosed in two patients (9.5%) and EAC in one (4.8%) patient. Factors associated with BE included male gender (OR 3.00, 1.21-7.46), age at last LS EGD (OR 1.04, 1.01-1.08), presence of hiatal hernia (OR 20.09, 4.57-88.23), hiatal hernia > 3 cm (OR 11.25, 2.41-51.94), and GERD (OR 3.39, 1.32-8.67). No MMR PV was associated with BE. BE was diagnosed in 1 of 15 patients undergoing EGD surveillance for LS and nearly 10% had dysplasia including one EAC. Risk factors associated with BE in LS are similar to those established for BE in the general population. More studies are needed to evaluate if an association between BE and LS exists.	esophagus
Transferrin and Prealbumin Identify Esophageal Cancer Patients with Malnutrition and Poor Prognosis in Patients with Normal Albuminemia: A Cohort Study.	In this study, we aimed to analyze whether serum prealbumin and transferrin have a higher sensitivity than albumin for detecting malnutrition and predicting survival in esophageal cancer patients. A total of 212 patients were prospectively enrolled. Serum albumin, prealbumin, and transferrin were analyzed by enzyme-linked immunosorbent assays. The association of nutritional markers with survival was analyzed. We found that malnutrition was presented in 44.5% of the patients, while 56.6% were unaware of their body weight change. The area under the curve for diagnosing malnutrition was largest for prealbumin, followed by transferrin and albumin, with optimal breakpoints of 21 mg/dL, 206 mg/dL, and 4.3 g/dL, respectively, for diagnosing malnutrition. The diagnostic sensitivity for malnutrition was 34.1-63.4% with a single marker and this increased to 80.5% with all 3 markers. In patients with normal albuminemia (≥ 4.3 g/dL), a low level of prealbumin and/or transferrin predicted malnutrition and poor prognosis. Multivariate Cox regression analysis confirmed that a low level of the nutritional marker was an independent poor prognostic factor. In conclusion, serum prealbumin and transferrin outperformed albumin in identifying esophageal cancer patients with malnutrition and poor prognosis. Checking all three markers will help with the early diagnosis of malnutrition and enable timely intervention.	esophagus
The Role of Toll-like Receptors in Esophageal Cancer.	Esophageal adenocarcinoma (AC) develops through Barrett's esophagus (BE) and columnar dysplasia, preceded by gastro-esophageal reflux disease (GERD). Incidence of esophageal squamous cell carcinoma (SCC) is increased with tobacco smoking and alcohol abuse. Toll-like receptors (TLRs) can act as prognostic factors and potential therapeutic targets of esophageal cancer. TLRs, an important family of pattern recognition receptors, allow immune cells to recognize pathogens triggering inflammation. TLR-signaling pathway activates signaling-elements, regulating inflammatory response, possibly correlating to carcinogenesis. In the normal esophagus, TLRs recognize molecular patterns on microorganisms and inflammatory response produced by tissue-damage. TLR3, TLR4, TLR5, and TLR9 are expressed at increasing levels from GERD to AC. TLR4 is a mediator of proliferation in AC, while TRL1 and TLR4 over-expression in AC is related to poor prognosis and metastasis. Additionally, TLR3, TLR4, and TLR9 expression in SCC has been associated with lymphatic metastasis, whereas increased expression of TLR7 and TLR9 has been also associated with advanced disease. It seems that TLR expression can indicate esophageal metaplasia, dysplasia, and cancer. Herein, we aimed to present all available data regarding the relation of TLRs and esophageal cancer. They may represent significant and valuable diagnostic or prognostic factors for esophageal cancer.	esophagus
Murine Double Minute 2 Antagonist Nutlin-3 Enhanced Chemosensitivity in Esophageal Squamous Cell Carcinoma.	BACKGROUND/AIM: Murine double minute 2 (MDM2) is well known to inhibit p53 function and its over-expression is associated with poor prognosis in several human malignancies. Nutlin-3, a small-molecule inhibitor of MDM2, exerts antitumor effects on various solid tumors harboring wild-type p53. We aimed to clarify its effects on esophageal cancer. MATERIALS AND METHODS: We first examined the potential antitumor effects of nutlin-3 according to MDM2 status using esophageal carcinoma cell lines (KYSE 170/180). We then immunolocalized MDM2 immunoreactivity in 62 surgical cases of esophageal squamous cell carcinoma undergoing neoadjuvant chemotherapy followed by esophagectomy and correlated the findings with clinicopathological variables. RESULTS: MDM2 mRNA expression in KYSE 170 was significantly higher than that in KYSE 180 cells. No significant changes were detected in both cell lines when nutlin-3 was added. However, cell proliferation was significantly decreased in KYSE 170 cells treated with nutlin-3 and cisplatin compared to cisplatin alone but not in KYSE 180. MDM2 immunoreactivity was also significantly associated with poor sensitivity to neoadjuvant chemotherapy in the cases examined. CONCLUSION: The combination of nutlin-3 with chemotherapeutic agents may become a novel therapeutic strategy in esophageal cancer over-expressing MDM2.	esophagus
Laparoscopic total fundoplication is superior to medical treatment for reducing the cancer risk in Barrett's esophagus: a long-term analysis.	The present study aims to compare the effectiveness of surgical and medical therapy in reducing the risk of cancer in Barrett's esophagus in a long-term evaluation. A prospective cohort was designed that compared Barrett's esophagus patients submitted to medical treatment with omeprazole or laparoscopic Nissen fundoplication. The groups were compared using propensity score matching paired by Barrett's esophagus length. A total of 398 patients met inclusion criteria. There were 207 patients in the omeprazole group (Group A) and 191 in the total fundoplication group (Group B). After applying the propensity score matching paired by Barrett's esophagus length, the groups were 180 (Group A) and 190 (Group B). Median follow-up was 80 months. Group B was significantly superior for controlling GERD symptoms. Group B was more efficient than Group A in promoting Barrett's esophagus regression or blocking its progression. Group B was more efficient than Group A in preventing the development of dysplasia and cancer. Logistic regression was performed for the outcomes of adenocarcinoma and dysplasia. Age and body mass index were used as covariates in the logistic regression models. Even after regression analysis, Group B was still superior to Group A to prevent esophageal adenocarcinoma or dysplasia transformation (odds ratio [OR]: 0.51; 95% confidence interval [CI]: 0.27-0.97, for adenocarcinoma or any dysplasia; and OR: 0.26; 95% CI: 0.08-0.81, for adenocarcinoma or high-grade dysplasia). Surgical treatment is superior to medical management, allowing for better symptom control, less need for reflux medication use, higher regression rate of the columnar epithelium and intestinal metaplasia, and lower risk for progression to dysplasia and cancer.	esophagus
End-to-side circular stapled versus side-to-side linear stapled intrathoracic esophagogastric anastomosis following minimally invasive Ivor-Lewis esophagectomy: comparison of short-term outcomes.	PURPOSE: The search for the optimal procedure for creation of a safe gastroesophageal intrathoracic anastomosis with a lower risk of leakage in totally minimally invasive Ivor-Lewis esophagectomy (TMIIL) is ongoing. In the present study, we compared the outcomes of end-to-side (with circular stapler [CS]) and side-to-side (with linear stapler [LS]) techniques for intrathoracic anastomosis during TMIIL performed in 2 European high-volume centers for upper gastrointestinal surgery. A propensity score method was used to compare the CS and LS groups. METHODS: We retrospectively evaluated patients with lower esophageal cancer or Siewert type 1 or 2 esophagogastric junction carcinoma who underwent a planned TMIIL esophagectomy, performed from January 2017 to September 2020. The anastomosis was created by a semi-mechanical technique using a LS in one center and by a mechanical technique using a CS in the other center. General features, operative techniques, pathology data, and short-term outcomes were analyzed. Statistical evaluations were performed on the whole cohort, stratifying the analyses by risk strata factors identified with the propensity scores, and on a subgroup of patients matched by propensity score. The primary endpoint of the study was the rate of anastomotic leakage in the two groups. Secondary endpoints included rates of anastomotic stricture and overall postoperative complications. RESULTS: Considering the whole population, 256 patients were included; of those, 220 received the anastomosis with a circular stapler (CS group), and 36 received the anastomosis with a linear stapler (LS group). No significant differences by group in terms of sex, age, American Society of Anesthesiologists physical status classification, and type of neoplasm were showed. The rate of anastomotic leakage did not differ in the two groups (9.6% CS vs. 5.6% LS, p = 0.438), as well as the rate of anastomotic stricture in the 3-month follow-up (0.9% CS vs. 2.8% LS, p = 0.367). The rate of chyle leakage and of pulmonary, cardiac, and infective complications was not significantly different in the groups. After propensity score matching, 72 patients were included in the analysis. The 2 obtained propensity score matched groups did not differ for any of the clinical and pathologic variables considered for the analysis, resulting in well-balanced cohorts. The results obtained on the whole population were confirmed in the matched groups. CONCLUSIONS: The results of our study suggest that both techniques for esophagogastric anastomosis during TMIIL are feasible, safe, and effective, with comparable rates of postoperative anastomotic leakage and stricture.	esophagus
Deubiquitinase USP8 increases ID1 stability and promotes esophageal squamous cell carcinoma tumorigenesis.	ID1 is a labile protein implicated in the development and progression of several malignant tumors, but the mechanisms regulating ID1 stability and function in human esophageal squamous cell carcinoma (ESCC) are largely unclear. In this study, we performed an immunoprecipitation assay to screen for deubiquitinases that may interact with ID1 and identified USP8 as a novel deubiquitinase for ID1. USP8 interacts with ID1, and increases the protein level and stability of ID1 by reducing its ubiquitination. Ectopic expression of USP8 promotes ESCC tumorigenesis by suppressing ID1 degradation, whereas knockdown of USP8 results in the opposite phenotypes in vitro and in vivo. Moreover, we found that TXNIP is a novel downstream target of ID1, and USP8 promotes ESCC tumorigenesis by activating the ID1-TXNIP pathway. Increased expression of USP8 and ID1 positively correlates with reduced TXNIP expression in ESCC tissues and predicts an advanced tumor stage. Overall, our data indicate that USP8 is a novel deubiquitinase for ID1 and show the importance of the USP8-ID1-TXNIP axis in promoting ESCC tumorigenesis.	esophagus
Identification of active components in Andrographis paniculata targeting on CD81 in esophageal cancer in vitro and in vivo.	BACKGROUND: Esophageal cancer (EC) is highly prevalent in Eastern Asia (including China) with high rates of mortality. The metastatic tendency in EC is associated with a poor prognosis. Our previous studies have demonstrated the suppressive effects of Andrographis paniculata water extract (APW) on metastatic esophageal cancer in vitro and in tumor-bearing mice models, as well as illustrated the potential underlying mechanism by transcriptome analysis. HYPOTHESIS: High expressions of several membrane protein tetraspanins were reported to lead to a high risk of metastasis in esophageal cancer in patients. We hypothesized that APW could downregulate the expression of tetraspanin CD81 in esophageal cancer cells and xenografts. METHODS: Human esophageal cancer cells EC109 and KYSE520 were incubated with APW for 24 hours in cell culture, while mice bearing EC109 xenograft tumors were treated with APW for 21 days. The expressions of CD81 in cancer cells and in tumors from mice were evaluated. Molecular docking and microscale thermophoresis analyses were applied to identify the components in APW interacting with CD81. The influence of the identified components on CD81 expression was further evaluated in EC109 cells. RESULTS: APW could significantly suppress the expressions of CD81 in both EC109 and KYSE520 cells in a concentration-dependent manner. Treatment of APW in xenograft-bearing mice reduces the metastasis in lungs, livers, and lymph nodes. The expression of CD81 in xenograft tumors of APW-treated mice was significantly lower than those of untreated control mice. The binding of andrographolide, bisandrographolide A, and bisandrographolide C with CD81 were elucidated by microscale thermophoresis. The suppressive effects of these compounds on the motility of EC109 cells, as well as CD81 protein and mRNA expressions, were further confirmed. CONCLUSION: This is the first time to demonstrate that andrographolide, bisandrographolide A, and bisandrographolide C, which are present in APW, bind to CD81 and suppress its function. These compounds are likely to be responsible for the anti-metastatic activities of APW in esophageal cancer.	esophagus
