Xiaoaiping injection as adjunct therapy for patients with advanced esophageal carcinoma: A protocol for a systematic review and meta-analysis.	BACKGROUND: Esophageal carcinoma (EC) is one of the worst malignant digestive neoplasms with a strong tendency of invasion and metastasis. Despite the improvement of diagnostic and therapeutic methods in the past decades, the prognosis of EC remains unsatisfactory. Xiaoaiping injection (XAPI), a famous traditional Chinese herbal medicine, has been widely applied as a promising adjunctive drug for EC. However, the exact effects and safety of XAPI have yet to be systematically investigated. We aimed to summarize the efficacy and safety of XAPI for the treatment of advanced EC through the meta-analysis, in order to provide scientific reference for the design of future clinical trials. METHODS: Relevant randomized controlled trials (RCTs) were searched from Cochrane Library, PubMed, Google Scholar, Web of Science, Excerpt Medica Database, Medline, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, China Scientific Journal Database and Wanfang Database. Papers in English or Chinese published from January 2000 to May 2020 will be included without any restrictions.Study selection and data extraction will be performed independently by 2 investigators. The clinical outcomes including overall response rate, complete response rate, overall survival, Disease-free survival, quality of life, immune function and adverse events, were systematically evaluated. Review Manager 5.3 and Stata 14.0 were used for data analysis, and the quality of the studies was also evaluated. RESULTS: The results of this study will be published in a peer-reviewed journal, and provide more evidence-based guidance in clinical practice. CONCLUSION: Our study will draw an objective conclusion of the effects of XAPI combined with conventional treatment for advanced EC and provide a helpful evidence for clinicians to formulate the best postoperative adjuvant treatment strategy for EC patients.

A chalcone inhibits the growth and metastasis of KYSE-4 esophageal cancer cells.	OBJECTIVE: To investigate the in vitro and in vivo anticancer effects of a chalcone against KYSE-4 esophageal cancer cells. METHODS: A chalcone was synthesized via the molecular hybridization strategy based on the anticancer activity of chalcone and dithiocarbamate scaffolds. The anticancer effects of different concentrations of the chalcone derivative were compared in esophageal cancer cells. RESULTS: This chalcone displayed strong inhibitory effects on esophageal cancer cell growth with an IC(50) of 1.06 μM in KYSE-4 cells. Analysis of the mechanism revealed that the derivative obviously inhibited KYSE-4 cell growth, migration, and invasion in a concentration-dependent manner. Furthermore, the compound regulated migration-related biomarkers (E-cadherin, N-cadherin, and Slug) and inhibited the Wnt/β-catenin pathway. According to western blotting, this chalcone suppressed the expression of proline-rich protein 11 (PRR11) in a concentration- and time-dependent manner. CONCLUSIONS: This chalcone might be a leading candidate for suppressing the growth and metastasis of esophageal cancer by downregulating PRR11 expression and inhibiting Wnt/β-catenin signaling.	esophagus
Circulating exosomal miRNAs as potential biomarkers for Barrett's esophagus and esophageal adenocarcinoma.	Exosomes, a class of extracellular vesicles, are small membrane-bound vesicles derived from almost all cell types that can play important roles in intercellular communication. Exosomes contain proteins, lipids, and nucleic acids that are obtained from the parental cells and participate in various pathophysiological processes, including cell growth, migration, inflammation, immune regulation, and tumor pathogenesis. Moreover, exosomes might be applied in clinical settings, such as diagnosis, treatment, and outcome prediction of diseases, including various cancers. The incidence rates of Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) have increased in recent decades, and studies have proposed specific factors that may contribute to the development and progression of these diseases. However, how exosomes play a role in this pathological process needs to be clarified. Studies have identified candidate microRNAs (miRNAs) that might be related to BE/EAC. Further studies are needed to ascertain whether circulating exosomal miRNAs are altered before or after disease onset, which could also help understand the pathophysiology of and find potential targets for prevention, diagnosis, and therapy in BE/EAC. This review summarizes recent findings on the features of circulating exosomal miRNAs in BE/EAC, which could be valuable for the early diagnosis, therapeutic approaches, and outcome prediction of BE/EAC.	esophagus
Long Noncoding RNA LINC00634 Functions as an Oncogene in Esophageal Squamous Cell Carcinoma Through the miR-342-3p/Bcl2L1 Axis.	Many long noncoding RNAs reportedly have tumor suppressive roles or are oncogenic in esophageal cancer. We have previously performed a chip-based expression analysis of primary esophageal cancer tissues and found that the expression of LINC00634 in these tissues was higher than that in nontumor tissues. Quantitative real-time-polymerase chain reaction, cell counting kit-8, flow cytometry, caspase3/7 assay, dual-luciferase reporter assay, and restore assay were used to detect the proliferative and apoptotic effects of LINC00634 in esophageal cancer cells. The results showed that the expression of LINC00634 in these tissues was higher than that in nontumor tissues and associated with tumor-node-metastasis (TNM) stage of patients. Knockdown of LINC00634 decreased cell viability and increased cell apoptosis levels in EC9706 and EC1 cells. LINC00634 could target Bcl2L1 through miR-342-3p. In this study, we show that LINC00634 is upregulated in esophageal cancer. We also show that the knockdown of LINC00634 decreased cell viability and increased cell apoptosis levels in EC9706 and EC1 cells through the miR-342-3p/Bcl2L1 axis.	esophagus
LncRNA FAM83H-AS1 promotes oesophageal squamous cell carcinoma progression via miR-10a-5p/Girdin axis.	Long non-coding RNAs (lncRNAs) have been well demonstrated to emerge as crucial regulators in cancer progression, and they can function as regulatory network based on their interactions. Although the biological functions of FAM83H-AS1 have been confirmed in various tumour progressions, the underlying molecular mechanisms of FAM83H-AS1 in oesophageal squamous cell carcinoma (ESCC) remained poorly understood. To address this, we treated human oesophageal cancer cell line Eca109 cells with TGF-β and found FAM83H-AS1 was notably overexpressed. In the present study, FAM83H-AS1 was observed to be significantly up-regulated in ESCC tissues and was associated with TNM stage, pathological differentiation and lymph node metastasis. FAM83H-AS1 reinforced oesophageal cancer cell proliferation, migration and invasion, and participated in epithelial-to-mesenchymal transition (EMT) process at mRNA and protein levels. In addition, a concordant regulation between FAM83H-AS1 and its sense strand FAM83H was detected at the transcriptional and translational levels. Furthermore, FAM83H-AS1 could act as competing endogenous RNA to affect the expression of Girdin by sponging miR-10a-5p verified by RIP and luciferase reporter assays. Consequently, the study provided a unique perspective of FAM83H-AS1 in ESCC progression, which may be considered as potential biomarker and therapeutic target for ESCC therapy.	esophagus
Minichromosome maintenance 6 complex component identified by bioinformatics analysis and experimental validation in esophageal squamous cell carcinoma.	Esophageal squamous cell carcinoma (ESCC), the main subtype of esophageal cancer (EC), is a common lethal type of cancer with a high mortality rate. The aim of the present study was to select key relevant genes and identify potential mechanisms involved in the development of ESCC based on bioinformatics analysis. Minichromosome maintenance 6 complex component (MCM6) has been identified to be upregulated in multiple malignancies; however, its contributions to ESCC remain unclear. For the purposes of the present study, four datasets were downloaded from the Gene Expression Omnibus (GSE63941, GSE26886, GSE17351 and GSE77861), and the intersection of the differentially expressed genes was obtained using a Venn diagram. The protein‑protein interaction was then constructed, and the modules were verified by Cytoscape, in which the key genes have a high connectivity degree with other genes. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway were subsequently filtered out to analyze the development of ESCC. MCM6, an upregulated gene, was selected and connected with most of the other genes, for further research validation. The expression levels of MCM6 were then assessed using the Oncomine, GEPIA and UALCAN databases and validated in both ESCC tissues samples and cell lines by immunohistochemistry and RT‑qPCR. Cell counting kit‑8 (CCK‑8), flow cytometry, wound healing and Transwell assays were used to determine the proliferation, apoptosis, cell cycle, migration and invasion of ESCC cells. A total of 24 genes were identified by a series of bioinformatics analyses and the results revealed that the genes were associated with DNA replication and cell cycle. Experimental validation revealed that MCM6 expression was significantly elevated in both ESCC tissues and cell lines. The results were consistent with those of bioinformatics analysis. Furthermore, the knockdown of MCM6 inhibited cell proliferation, migration and invasion and promoted cell apoptosis, and made cells arrested in S stage. In summary, the findings of bioinformatics analysis provided a novel hypothesis for ESCC progression. In particular, the aberrantly elevated expression of MCM6 is a potential biomarker for ESCC diagnosis and treatment.	esophagus
Germline BRCA2 Truncating Mutation in Familial Esophageal Squamous Cell Carcinoma: A Case Controlled Study in China.	BACKGROUND Germline mutations of BRCA2 have been reported in various malignancies. We investigated BRCA2 germline mutations in familial clusters with esophageal squamous cell carcinoma (ESCC). MATERIAL AND METHODS We screened the DNA of familial ESCC patients for BRCA2 germline mutations with whole gene sequencing. Multiple BRCA2 mutations including one novel splice variant, c.426-2A>G were identified. Other family members, sporadic ESCC patients, and controls were also assessed for the novel mutation. RESULTS The mutation c.426-2A>G was found in 2 affected ESCC sisters and 7 other family members. The splice variant mutation results in exon 5 skipping with a frame shift leading to a premature stop codon in exon 6 and truncation. Novel mutation tracking ruled out single nucleotide polymorphism (SNP) in 100 chromosomes of healthy individuals. CONCLUSIONS BRCA2 germline mutation in ESCC patients may play a role in genetic susceptibility to familial ESCC. Genetic analysis of BRCA2 in patients with familial ESCC could provide opportunities for targeted therapies.	esophagus
Efficacy and safety of endoscopic submucosal tunnel dissection vs endoscopic submucosal dissection for early superficial upper gastrointestinal precancerous lesions and tumors: A meta-analysis.	OBJECTIVE: Endoscopic submucosal tunnel dissection (ESTD) is a new treatment for superficial upper gastrointestinal precancerous lesions and tumors. However, its safety and efficacy for treating these lesions is still uncertain. This meta-analysis aimed to compare the efficacy and safety of ESTD with those of endoscopic submucosal dissection (ESD) in treating early superficial upper gastrointestinal precancerous lesions and tumors. METHODS: Electronic databases, including EMBASE, PubMed, Cochrane Library and the Web of Science, were systematically searched for articles published up to 1 April 2020. The primary outcomes were complete and en bloc resection rates of the lesions. The secondary outcomes included operation time, speed of dissection, complication and recurrence rates. The Newcastle-Ottawa quality assessment scale was used to evaluate the quality of the studies. RESULTS: Seven studies were included in the final meta-analysis. The complete and en bloc resection rates of early superficial esophageal lesions as well as the en bloc resection rate of early superficial gastric lesions were similar between the ESTD and ESD groups. Compared with the ESD group, the ESTD group had a higher en bloc resection rate for early superficial gastric lesions. A faster dissection speed was observed in both superficial esophageal and gastric lesions. In gastric lesions, the operation time of the ESTD group was shorter than that of the ESD group, while it did not differ for esophageal lesions. There were no obvious differences in bleeding and perforation rates between the groups. CONCLUSION: As an endoscopic technique for treating early superficial upper gastrointestinal lesions, ESTD is as safe as and more effective than ESD, especially for gastric lesions.	esophagus
QOLEC2: a randomized controlled trial on nutritional and respiratory counseling after esophagectomy for cancer.	BACKGROUND: Esophagectomy for cancer strongly impairs quality of life. The aim of this trial was to evaluate the effect of the nutritional and respiratory counseling on postoperative quality of life. METHODS: At hospital discharge, patients were randomized into four groups receiving respectively: nutritional and respiratory counseling, nutritional counseling alone, respiratory counseling alone, or standard care. The main endpoint was the impairment in quality of life in the first month after surgery. Linear mixed effect models were estimated to assess mean score differences (MDs) in quality of life scores. RESULTS: Patients receiving nutritional counseling reported less appetite loss (MD - 17.7, 95% CI - 32.2 to -3.3) than those not receiving nutritional counseling at 1 month after surgery. Dyspnea was similar between patients receiving vs. those not receiving respiratory counseling (MD - 3.1, 95% CI - 10.8 to 4.6). Global quality of life was clinically similar between patients receiving vs. those not receiving nutritional counseling over time (MD 0.9, 95% CI - 5.5 to 7.3), as well as in patients receiving vs. those not receiving respiratory counseling over time (MD 0.7, 95% CI - 5.9 to 7.2). CONCLUSIONS: Intensive postoperative care does not affect global quality of life even if nutritional counseling reduced appetite loss.	esophagus
Clinical response assessment on DW-MRI compared with FDG-PET/CT after neoadjuvant chemoradiotherapy in patients with oesophageal cancer.	PURPOSE: In about 30% of patients treated with neoadjuvant chemoradiotherapy (nCRT) followed by surgical resection for locally advanced oesophageal cancer no vital tumour is found in the resection specimen. Accurate clinical response assessment is critical if deferral from surgery is considered in complete responders. Our study aimed to compare the performance of MRI and of FDG-PET/CT for the detection of residual disease after nCRT. METHODS: Patients with oesophageal cancer eligible for nCRT and oesophagectomy were prospectively included. All patients underwent FDG-PET/CT and MRI before and between 6 and 8 weeks after nCRT. Two radiologists scored the MRI scans, and two nuclear medicine physicians scored the FDG-PET/CT scans using a 5-point score for residual disease. Histopathology after oesophagectomy represented the reference standard. Sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) were calculated for detection of residual tumour (ypT+), residual nodal disease (ypN+), and any residual disease (ypT+Nx/ypT0N+). RESULTS: Seven out of 33 (21%) patients had a pathological complete response. The AUCs for individual readers to detect ypT+ were 0.71/0.70 on diffusion-weighted (DW)-MRI and 0.54/0.57 on FDG-PET/CT, and to detect ypN+ were 0.89/0.81 on DW-MRI and 0.75/0.71 on FDG-PET/CT. The AUCs/sensitivities/specificities for the individual readers to detect any residual disease were 0.74/92%/57% and 0.70/96%/43% on MRI; these were 0.49/69%/29% and 0.60/69%/43% on FDG-PET/CT, respectively. CONCLUSION: MRI reached higher diagnostic accuracies than FDG-PET/CT for the detection of residual tumour in oesophageal cancer patients at 6 to 8 weeks after nCRT.	esophagus
SDCBP/MDA-9/syntenin phosphorylation by AURKA promotes esophageal squamous cell carcinoma progression through the EGFR-PI3K-Akt signaling pathway.	SDCBP is an adapter protein containing two tandem PDZ domains mediating cell adhesion. The role and underlying molecular mechanism of SDCBP in ESCC remain obscure. Here, we report that SDCBP is frequently overexpressed in ESCC tissues and cells compared to normal controls and that its overexpression is correlated with late clinical stage and predicts poor prognosis in ESCC patients. Functionally, high expression of SDCBP is positively related to ESCC progression both in vitro and in vivo. Furthermore, mechanistic studies show that SDCBP activates the EGFR-PI3K-Akt signaling pathway by binding to EGFR and preventing EGFR internalization. Moreover, we provide evidence that AURKA binds to SDCBP and phosphorylates it at the Ser131 and Thr200 sites to inhibit ubiquitination-mediated SDCBP degradation. More importantly, the sites at which AURKA phosphorylates SDCBP are crucial for the EGFR signaling-mediated oncogenic function of SDCBP. Taken together, we propose that SDCBP phosphorylation by AURKA prevents SDCBP degradation and promotes ESCC tumor growth through the EGFR-PI3K-Akt signaling pathway. Our findings unveil a new AURKA-SDCBP-EGFR axis that is involved in ESCC progression and provide a promising therapeutic target for ESCC treatment in the clinic.	esophagus
Treatment of Locally Advanced Esophageal Carcinoma: ASCO Guideline.	PURPOSE: To develop an evidence-based clinical practice guideline to assist in clinical decision making for patients with locally advanced esophageal cancer. METHODS: ASCO convened an Expert Panel to conduct a systematic review of the more recently published literature (1999-2019) on therapy options for patients with locally advanced esophageal cancer and provide recommended care options for this patient population. RESULTS: Seventeen randomized controlled trials met the inclusion criteria. Where possible, data were extracted separately for squamous cell carcinoma and adenocarcinoma. RECOMMENDATIONS: Multimodality therapy for patients with locally advanced esophageal carcinoma is recommended. For the subgroup of patients with adenocarcinoma, preoperative chemoradiotherapy or perioperative chemotherapy should be offered. For the subgroup of patients with squamous cell carcinoma, preoperative chemoradiotherapy or chemoradiotherapy without surgery should be offered. Additional subgroup considerations are provided to assist with implementation of these recommendations. Additional information is available at www.asco.org/gastrointestinal-cancer-guidelines.	esophagus
Surgical oncology in patients aged 80 years and older is associated with increased postoperative morbidity and mortality: A systematic review and meta-analysis of literature over 25 years.	BACKGROUND: The study aim is to analyze the evolution over the last 25 years of the results reported after abdominal oncological surgery in patients aged 80 years of age and older. The primary endpoint was morbidity and mortality in this group of patients; the secondary endpoint was overall survival. METHODS: A systematic search strategy was used to browse through Medline/PubMed, EMBASE, Scopus, ClinicalTrials.gov, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials using a combination of standardized index terms. Studies published between 1997 and 2017 were selected. Only those studies that showed morbidity and mortality after digestive and hepatobiliary tract oncological surgery in individuals aged 80 years and older were included. The PROSPERO registration number is CRD42018087921. PRISMA and MOOSE guidelines were applied. RESULTS: A total of 79 studies were included, categorized by origin of malignancy: esophageal (7), stomach (26), liver (4), pancreas (19), and colorectal (23). Compared with the non-elderly group, the elderly group had similar esophageal morbidity with higher mortality (RR 2.51, 1.50 to 4.21; P = 0.0005); higher gastric morbidity (RR 1.25, 1.09 to 1.43; P = 0.001), and mortality (RR 2.51, 1.81 to 3.49; P = 0.0001); similar liver morbidity and mortality; higher pancreatic morbidity (RR 1.17, 1.03 to 1.33; P = 0.02) and mortality (RR 2.37, 1.86 to 3.03; P < 0.00001); and similar colorectal morbidity with higher mortality (RR 4.44, 1.91 to 10.32; P = 0.005). CONCLUSION: Oncological surgery of most abdominal visceral tumors is associated with increased morbidity and mortality in patients older than 80 years.	esophagus
Transhiatal laparoscopic esophagectomy with extended lymphadenectomy guided by green-indocyanine imaging for adenocarcinoma of the esophagogastric junction.	INTRODUCTION: Surgical treatment for adenocarcinoma of the esophagogastric junction (AEGJ) has been long-established, from resection margins to the extension of lymphadenectomy [1,2,4]. The addition of cyanine dye, namely indocyanine green (ICG), to identify suspicious lymph nodes (LN) and evaluate organ vascularization may improve results and outcomes [3]. VIDEO: A 58-year-old female patient with Siewert type II AEGJ was administered mFLOX neoadjuvant treatment. After three cycles, she underwent surgical treatment. The day before surgery, an upper endoscopy was performed to inject 0.2 ml ICG 0.5 cm from the proximal and distal tumor margins. The patient underwent laparoscopic transhiatal esophagectomy with extended lymphadenectomy due to a 4 cm distal esophagus compromised margin. We describe the primary steps of the procedure and demonstrate the role of the ICG in the lymphadenectomy. RESULTS: Surgery was carried out laparoscopically with a cervical approach (McKeown access), and posterior mediastinal gastric tube reconstruction and cervical gastroplasty were performed. During the standard lymphadenectomy, we observed an ICG-positive LN in station 10, which was found positive in the subsequent pathology examination. After these findings, we performed an extended lymphadenectomy through the splenic hilum. The final pathologic assessment was T3N2 (two perigastric and one positive LN at station 10 among 60 retrieved LN). The operative time was 360 min. The patient started a liquid diet on the seventh postoperative day, and she was discharged on the tenth postoperative day. CONCLUSIONS: ICG may be helpful to guide both extended lymphadenectomy and distal margin evaluation in transhiatal laparoscopic esophagectomy.	esophagus
