GPR12 inhibits migration and promotes apoptosis in esophageal cancer and hypopharyngeal cancer cells.	BACKGROUND: G protein-coupled receptor 12 (GPR12) is an orphan receptor with no confirmed endogenous ligands. It plays important roles in both physiological and pathological conditions such as neurogenesis and neural inflammation. However, it remains unclear whether GPR12 regulates carcinogenesis and progression in head and neck squamous cell carcinoma (HNSCC), such as esophageal cancer (EC) and hypopharyngeal cancer (HC). METHODS: The Cancer Genome Atlas (TCGA) database was applied to explore the expression of GPR12. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of GPR12 in cancer tissues. Wound healing and transwell assays were carried out to verify the effect of GPR12 on cell migration. Flow cytometric analysis and caspase-Glo 3/7 assay were carried out to verify the influence of GPR12 on cell apoptosis. Western blotting was used to measure the expression of proteins related to migration and apoptosis. RESULT: The qRT-PCR analyses showed that the expression of GPR12 decreased in EC and HC than that in their paired adjacent normal tissues. Wound healing assay and transwell assay demonstrated that GPR12 inhibited tumor cell migration. Flow cytometry analysis and Caspase-Glo 3/7 Assay suggested that GPR12 promoted apoptosis. The mechanism of GPR12 may function via modulating caspase-7, E-cadherin, and α-catenin in EC and HC cells. CONCLUSION: In conclusion, GPR12 induced apoptosis by activating caspase-7 and inhibited migration through epithelial-to-mesenchymal transition (EMT) in EC and HC. Our findings demonstrated that GPR12 as a potential tumor suppressor mediated cell migration and apoptosis in EC and HC.	esophagus
Does a high Mandard score really define a poor response to chemotherapy in oesophageal adenocarcinoma?	BACKGROUND: A high Mandard score implies a non-response to chemotherapy in oesophageal adenocarcinoma. However, some patients exhibit tumour volume reduction and a nodal response despite a high score. This study examines survival and recurrence patterns in these patients. METHODS: Clinicopathological factors were analysed using multivariable Cox regression assessing time to death and recurrence. Computed tomography-estimated tumour volume change was examined in a subgroup of consecutive patients. RESULTS: Five hundred and fifty-five patients were included. Median survival was 55 months (Mandard 1-3) and 21 months (Mandard 4 and 5). In the Mandard 4 and 5 group (332 patients), comparison between complete nodal responders and persistent nodal disease showed improved survival (90 vs 18 months), recurrence rates (locoregional 14.75 vs 28.74%, systemic 24.59 vs 48.42%) and circumferential resection margin positivity (22.95 vs 68.11%). Complete nodal response independently predicted improved survival (hazard ratio 0.34 (0.16-0.74). Post-chemotherapy tumour volume reduction was greater in patients with a complete nodal response (-16.3 vs -7.7 cm(3), p = 0.033) with no significant difference between Mandard groups. CONCLUSION: Patients with a complete nodal response to chemotherapy have significantly improved outcomes despite a poor Mandard score. High Mandard score does not correspond with a non-response to chemotherapy in all cases and patients with nodal downstaging may still benefit from adjuvant chemotherapy.	esophagus
Genome-Wide DNA Methylation Profiling of Esophageal Squamous Cell Carcinoma from Global High-Incidence Regions Identifies Crucial Genes and Potential Cancer Markers.	Epigenetic mechanisms such as aberrant DNA methylation (DNAme) are known to drive esophageal squamous cell carcinoma (ESCC), yet they remain poorly understood. Here, we studied tumor-specific DNAme in ESCC cases from nine high-incidence countries of Africa, Asia, and South America. Infinium MethylationEPIC array was performed on 108 tumors and 51 normal tissues adjacent to the tumors (NAT) in the discovery phase, and targeted pyrosequencing was performed on 132 tumors and 36 NAT in the replication phase. Top genes for replication were prioritized by weighting methylation results using RNA-sequencing data from The Cancer Genome Atlas and GTEx and validated by qPCR. Methylome analysis comparing tumor and NAT identified 6,796 differentially methylated positions (DMP) and 866 differential methylated regions (DMR), with a 30% methylation (Δβ) difference. The majority of identified DMPs and DMRs were hypermethylated in tumors, particularly in promoters and gene-body regions of genes involved in transcription activation. The top three prioritized genes for replication, PAX9, SIM2, and THSD4, had similar methylation differences in the discovery and replication sets. These genes were exclusively expressed in normal esophageal tissues in GTEx and downregulated in tumors. The specificity and sensitivity of these DNAme events in discriminating tumors from NAT were assessed. Our study identified novel, robust, and crucial tumor-specific DNAme events in ESCC tumors across several high-incidence populations of the world. Methylome changes identified in this study may serve as potential targets for biomarker discovery and warrant further functional characterization. SIGNIFICANCE: This largest genome-wide DNA methylation study on ESCC from high-incidence populations of the world identifies functionally relevant and robust DNAme events that could serve as potential tumor-specific markers.

Topical oro-dispersible budesonide tablets for stricture prevention after near circumferential ESD for esophageal squamous cell cancer - a case report.	BACKGROUND:  Endoscopic resection is the treatment of choice for early esophageal cancers. However, resections comprising more than 70-80 % of the circumference are associated with a high risk of stricture formation. Currently, repetitive local injections and/or systemic steroids are given for prevention. CASE REPORT: We present here the case of a 78-year-old male patient who had a near circumferential endoscopic submucosal dissection for a pT1a mm, L0, V0, R0, G2 esophageal squamous cell cancer. At the end of endoscopic resection, 80 mg of triamcinolone was injected locally. The patient was then treated with oro-dispersible budesonide tablets (2 × 1 mg/day) and nystatin (4 × 100 000 I.E.) for 8 weeks. This treatment resulted in complete healing without any stricture formation and did not result in any complications. DISCUSSION:  Treatment with orodispersible budesonide tablets could help prevent strictures after large endoscopic resections in the esophagus.	esophagus
Esophageal Epidermoid Metaplasia: Clinical Characteristics and Risk of Esophageal Squamous Neoplasia.	INTRODUCTION: Esophageal epidermoid metaplasia (EEM) is a rare disease. METHODS: Patients with EEM diagnosed between 2014 and 2020 were reviewed. RESULTS: Forty EEM cases were identified. EEM occurred in 9 (23%) patients before, concordant, or after esophageal squamous cell carcinoma (ESCC). EEM was associated with previous esophageal lichen planus in 5 patients, Barrett's esophagus 7, and esophageal adenocarcinoma 1. EEM was focal in 28 (70%) or diffuse in 12 (30%) and not detected in 45% on recent previous endoscopy. DISCUSSION: EEM is a premalignant underrecognized condition associated with multiple conditions. Close follow-up or endoscopic treatment may be warranted because of its ESCC association.	esophagus
miR-20b and miR-125a promote tumorigenesis in radioresistant esophageal carcinoma cells.	Radiation therapy is an effective method in the management of esophageal cancer. MicroRNAs (miRNAs) have been reported to play an important role in tumorigenesis. However, the roles of specific miRNAs in radioresistant esophageal cancer remain to be investigated. In present study, the relative expression level of miR-20b-5p and miR-125a-5p were evaluated by quantitative Real-time polymerase chain reaction. Cell counting Kit-8 assay, wound-healing assay, transwell assay were used to assess cell proliferation, cell migration and cell invasion. TUNEL and Annexin V-FITC assays were applied to evaluate cell apoptosis. Dual-luciferase reporter gene assay was conducted to identify direct targets of miRNAs. The protein expression level was assessed by Western blot. The results indicated that miR-20b-5p was increased in radioresistant KYSE-150R cells compared with KYSE-150 cells, whereas miR-125a-5p was downregulated. MiR-20b-5p upregulation promoted cell proliferation, migration, invasion, and the EMT process, and decreased apoptosis by negatively regulating PTEN. MiR-125a-5p inhibited cell proliferation, migration, invasion, the EMT process and it induced apoptosis by negatively regulating IL6R. These data indicate that miR-20b-5p and miR-125a-5p promote tumorigenesis in radioresistant KYSE-150R cells and have the potential to be used as novel therapeutic targets for the treatment of esophageal cancer.	esophagus
Safety and feasibility of total laparoscopic radical resection of Siewert type II gastroesophageal junction adenocarcinoma through the left diaphragm and left thoracic auxiliary hole.	BACKGROUND: The incidence of adenocarcinoma of the esophagogastric junction (AEG) is rising every year; however, the mode of operation for Siewert II AEG is still controversial. Accumulating evidence has shown that transabdominal surgery is better than transthoracic surgery for Siewert II AEG with esophageal invasion < 3 cm. In patients with obesity, a large tumor size, and high transection of the esophagus, the transabdominal esophageal hiatus approach for lower mediastinal lymph node dissection and posterior mediastinal anastomosis is difficult. Thus, total laparoscopic radical resection of Siewert II AEG is carried out through the left diaphragm and left chest auxiliary hole for the optimal surgical field of vision and space. In this prospective study, we assessed the feasibility of carrying out the procedure abdominally through the left diaphragm and auxiliary hole. METHODS: Ten patients with Siewert II AEG were recruited between April and June 2019. Siewert II AEG was treated by total laparoscopy through the left diaphragm and left chest auxiliary hole. Clinicopathological features, surgical data, and adverse events were collected and analyzed in this prospective study. RESULTS: The average duration of the operation was 348 ± 37.52 min, lower mediastinal dissection took 20.6 min, the OrVil anastomosis time was 29.8 min, the time necessary to suture the seromuscular layer through the left thoracic auxiliary hole was 11 min, the safety margin was 3.2 cm, and the total number of lymph nodes dissected was 40.6. The number of lower mediastinal lymph nodes dissected was 6.2. The rate of lymph node metastasis in the N110 group was 9 ± 12.45%, and the average intraoperative blood loss was 170 ± 57.47 mL. No anastomotic leakage or anastomotic stricture occurred after the operation. The time of intestinal function recovery was 2 days, and the first time of enteral nutrition through a jejunal nutrition tube was 2.4 days. No tumor recurrence was found in 10 patients at 1 year postoperatively. CONCLUSION: Total laparoscopic radical resection through the left diaphragm and left thoracic auxiliary hole for Siewert II AEG patients is feasible and safe. Thus, it may be a good surgical alternative for patients with esophageal tumors invading less than 3 cm. TRIAL REGISTRATION: ChiCTR, ChiCTR2000034286.

Polymorphism of FGD4 and myelosuppression in patients with esophageal squamous cell carcinoma.	Background: Chemotherapy-related adverse events may restrain taxane/cisplatin administration as a regimen for patients with esophageal squamous cell carcinoma. Genetic polymorphisms may contribute to adverse event susceptibility. Method & results: The authors genotyped ten SNPs from five genes (rs1045642, rs2032582 and rs3213619 of ABCB1; rs2231137 and rs2231142 of ABCG2; rs246221 of ABCC1; rs3740066 of ABCC2; and rs10771973, rs12296975 and rs1239829 of FGD4) in 219 patients with esophageal squamous cell carcinoma treated with taxane/cisplatin. Patients with severe toxicities were compared with those with minor or no adverse events by unconditional logistic regression models and semi-Bayesian shrinkage. After adjustment for age and sex, with the null prior, FGD4 rs1239829 was statistically significantly related to grade 3-4 leukopenia (odds ratio [95% CI] in dominant model = 1.77 [1.04-3.03]). Conclusion: The minor allele of FGD4 rs1239829 was related to grade 3-4 leukopenia in patients with esophageal squamous cell carcinoma treated with taxane/cisplatin, with unclear biological mechanism.	esophagus
Signet Ring Cell Features are Associated with Poor Response to Neoadjuvant Treatment and Dismal Survival in Patients with High-Grade Esophageal Adenocarcinoma.	BACKGROUND: While the prognosis of patients with locoregional esophageal adenocarcinoma (EAC) has improved in the neoadjuvant treatment (NAT) era, high-grade histology (G3) is still associated with a limited treatment response. We sought to investigate oncologic outcomes in patients after esophagectomy for G3 EAC and to identify predictors of poor survival among these patients. METHODS: Patients with EAC who underwent resection with curative intent in 2011-2018 were divided by histologic grade (G3, G1/2) and compared for overall survival (OS). Cox regression was performed to analyze the response to NAT and the predictive role of signet ring cell (SRC) features. RESULTS: The cohort included 163 patients, 94 (57.7%) with G3 histology. NAT was administered to 69 (73.4%) patients. Following resection, OS in the G3 EAC group was 30 months (95% confidence interval [CI] 23.9-36.1). On univariate analysis, G3 disease (p = 0.050) and SRC features (p = 0.019) predicted low OS. Median survival in the G3 EAC group was worse in patients with SRC histology (18 months, 95% CI 8.6-27.4) than those without (30 months, 95% CI 23.8-36.1; p = 0.041). No patients with SRC histology were alive at 5 years of follow-up. Among all patients administered NAT, 88.2% of those with SRC showed minimal or no pathologic response and only 27.8% were downstaged. CONCLUSIONS: High-grade histology was found in most patients with EAC and predicted poor survival and treatment response. SRC features in patients with G3 disease were associated with lower OS. The benefit of NAT for G3 EAC in patients with SRC histology appears limited.	esophagus
Upregulated long non‑coding RNA LincIN promotes tumor progression via the regulation of nuclear factor 90/microRNA‑7/HOXB13 in esophageal squamous cell carcinoma.	Long non‑coding RNA LincIN has been reported to be overexpressed and to be involved in the metastasis of breast cancer. However, the expression and role of LincIN in esophageal squamous cell carcinoma (ESCC) remain unsolved. In the present study, LincIN expression was examined in ESCC by RT‑qPCR, and the roles of LincIN in ESCC were determined using cell growth, migration and invasion assays. In addition, the effects of LincIN on nuclear factor 90 (NF90) and microRNA/miR (miR)‑7 were examined by RNA immunoprecipitation assay, RT‑qPCR, dual‑luciferase reporter assay and western blot analysis. The results revealed that LincIN expression was significantly increased in ESCC tissues and cell lines. The increased expression of LincIN was positively associated with invasion depth, lymph node metastasis, TNM stage and a poor prognosis. Functional assays revealed that the overexpression of LincIN promoted ESCC cell growth, migration and invasion. Mechanistic analysis revealed that LincIN physically bound to NF90, enhanced the binding between NF90 and primary miR‑7 (pri‑miR‑7), and further enhanced the inhibitory effects of NF90 on miR‑7 biogenesis. Therefore, LincIN downregulated miR‑7 expression in ESCC. The expression of miR‑7 inversely correlated with that of LincIN in ESCC tissues. By downregulating miR‑7, LincIN increased the expression of HOXB13, a target of miR‑7. The overexpression of miR‑7 or the depletion of HOXB13 both attenuated the tumor‑promoting roles of LincIN in ESCC cell growth, migration and invasion. On the whole, the findings of the present study suggest that LincIN is overexpressed and plays an oncogenic role in ESCC via the regulation of the NF90/miR‑7/HOXB13 axis. Thus, LincIN may prove to be a promising prognostic biomarker and therapeutic target for ESCC.	esophagus
Profiles of immune cell infiltration and immune-related genes in the tumor microenvironment of esophageal squamous cell carcinoma.	BACKGROUND: As a complex system participating in tumor development and progression, the tumor microenvironment was poorly understood in esophageal cancer especially squamous cell carcinoma (ESCC). METHODS: ESTIMATE algorithm is used to investigate tumor-infiltrating immune cells and prognostic genes which were associated with the tumor microenvironment in ESCC. RESULTS: Based on the immune and stromal scores, ESCC samples were divided into high and low score groups and 299 overlapping differentially expressed genes were identified. Functional enrichment analysis showed that these genes were mainly involved in muscle-related function. Prognostic genes including COL9A3, GFRA2, and VSIG4 were used to establish a risk prediction model using Cox regression analyses. Then multivariate analysis showed that COL9A3 was an independent discriminator of a better prognosis. Kaplan-Meier survival analysis showed that the expression of COL9A3 was significantly correlated with the overall survival of ESCC patients. The area under the curve for the risk model in predicting 1- and 3- year survival rates were 0.660 and 0.942, respectively. The risk score was negatively correlated with plasma cells, while positively correlated with the proportions of activated CD4 memory T cells, M1 Macrophages and M2 Macrophages (p < 0.001 for each comparison). Gene set enrichment analysis suggested that both immune response and immune system process gene sets were significantly enriched in high-risk group. CONCLUSIONS: Our study provided a comprehensive understanding of the TME in ESCC patients. The establishment of the risk model is valuable for the early identification of high-risk patients to facilitate individualized treatment and improve the possibility of immunotherapy response.	esophagus
Survival differences between chemotherapy and chemoradiotherapy in metastatic esophageal cancer: a propensity score-matched study based on the SEER database.	BACKGROUND: The aim of this study was to explore the impact of chemotherapy (CT) and chemoradiotherapy (CRT) on prognosis in metastatic esophageal cancer (mEC) patients. METHODS: Information of patients with mEC from 2010 to 2016 was retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. Demographic and clinical data between CT and CRT groups were compared. Propensity score matching (PSM) analysis was used to reduce the influence of potential confounding factors. Multivariate Cox regression analysis was used to evaluate prognostic factors. Moreover, interaction tests and survival analyses were performed to determine whether pathological type conferred any survival benefits in subgroups. RESULTS: A total of 3,352 mEC patients were recruited including 1,697 CT patients and 1,655 CRT patients. In multivariable Cox regression, marital status, gender and pathological type were identified as independent prognostic factors for mEC. There was no statistical significance between the CT group and CRT group in overall survival (OS) and cancer-specific survival (CSS) in the matched and unmatched cohort. In subgroup analyses, patients with esophageal adenocarcinoma (EAC) undergoing CT had favorable prognosis. However, in the subgroup of esophageal squamous cell carcinoma (ESCC), patients in the CT group had worse outcomes compared with patients in the CRT group. CONCLUSIONS: Patients with EAC and ESCC could respectively benefit from CT and CRT. Besides, we recommend individualizing the treatment strategy for mEC based on the pathological type.	esophagus
Transcervical Transtracheal Resection of Cervical Esophageal Smooth Muscle Tumor.	Cervical esophageal smooth muscle tumors are traditionally resected via lateral transcervical with or without video-assisted thoracoscopic approaches. Exposure is frequently limited, however, with risks of recurrent laryngeal nerve and posterior tracheal wall injury and jeopardization of cervical tracheal and cervical esophageal blood supply. We herein describe an anterior transcervical transtracheal approach to counter some of the aforementioned problems and avoid morbidities associated with thoracoscopic surgery when resecting smooth muscle tumors arising from the cervical esophagus.	esophagus
IL-32 Promotes the Radiosensitivity of Esophageal Squamous Cell Carcinoma Cell through STAT3 Pathway.	OBJECTIVE: This study is set out to determine the relationship between IL-32 and radiosensitivity of esophageal squamous cell carcinoma (ESCC). METHODS: Western blot was adopted for measuring IL-32 expression in Eca-109 and TE-10 cells. Eca-109 and TE-10 cells with interference or overexpression of IL-32 were treated with the presence or absence of X-ray irradiation. Then, the use of CCK8 assay was to detect proliferation ability, and effects of IL-32 expression on radiosensitivity of ESCC were tested by colony formation assay. The cell apoptosis was detected using flow cytometry. STAT3 and p-STAT expression, and apoptotic protein Bax were detected by western blot. RESULTS: Colony formation assay and CCK8 assay showed that compared with the NC group without treatment, the growth of the ESCC cells, that is Eca-109 and TE-10, was significantly inhibited in the OE+IR group with highly expressed IL-32 and irradiation. In flow cytometry analysis, in Eca-109 and TE-10 cells, highly expressed IL-32 combined with irradiation significantly increased apoptosis compared with the control group. Highly expressed IL-32 has a synergistic effect with irradiation, inhibiting STAT3 and p-STAT3 expression and increasing apoptotic protein Bax expression. CONCLUSION: IL-32 can improve the radiosensitivity of ESCC cells by inhibiting the STAT3 pathway. Therefore, IL-32 can be used as a new therapeutic target to provide a new attempt for radiotherapy of ESCC.	esophagus
Dermatomyositis with exfoliation of esophageal mucosa: A case report.	Dermatomyositis (DM) is a kind of idiopathic inflammatory myopathy characterized by chronic proximal skeletal muscle weakness and unique skin lesions. However, DM with exfoliation of esophageal mucosa is rare. A 36-year-old male patient complained of muscular soreness of extremities, dysphagia, and pharyngalgia was diagnosed with DM with exfoliation of esophageal mucosa. After treatment with glucocorticoid, immunosuppressant, acupuncture, and endoscopic submucosal dissection (ESD), the above symptoms were disappeared. During the 3-year follow-up period, the results of routine physical examination, laboratory examination, gastroscopy, and imaging examination were normal. High-dose of corticosteroid is needed in the initial treatment, but it must be reduced regularly to avoid adverse reactions. Acupuncture and ESD are also effective as adjuvant therapy.	esophagus
