The potential of herb medicines in the treatment of esophageal cancer.	Esophageal cancer (EC) is one of common malignant neoplasms in the world. Due to dietary habits, environmental factors, stress and so on, larger numbers of person are diagnose with EC every year. Currently, the clinical treatment of EC mainly includes radiotherapy, chemotherapy, surgical resection alone or combined strategy. These treatment options are insufficient and often associated with a number of side effects. Medicinal herbs containing Traditional Chinese Medicine (TCM) have been used as an adjunct treatment for alleviating the side effects of chemotherapy or radiotherapy and for improving the quality of life of cancer patients. The monomer compounds obtained from medicinal herbs also exhibit potential anti-cancer activity against various type cancer cell lines including esophageal cancer, and have the ability to enhance cancer cells sensitizing to chemotherapy or radiotherapy. In this review, we summarize some monomers and composite of medicinal herbs with anti-cancer activity for EC, and elaborate their mechanism of action. Understanding the exact mechanism of their actions may provide valuable information for their possible application in cancer therapy and prevention. This is beneficial for the use and development of medicinal herbs for diseases therapy in the future.	esophagus
A comparative study of quantitative assessment with fluorine-18-fluorodeoxyglucose positron-emission tomography and endoscopic ultrasound in oesophageal cancer.	OBJECTIVES: This study aims to assess the correlation between PET/CT and endoscopic ultrasound (EUS) parameters in patients with oesophageal cancer. PATIENTS AND METHODS: All patients who had complete PET/CT and EUS staging performed for oesophageal cancer at our centre between 2010 and 2016 were included. Images were retrieved and analysed for a range of parameters including tumour length, volume and position relative to the aortic arch. RESULTS: Seventy patients were included in the main analysis. A strong correlation was found between EUS and PET/CT in the tumour length, the volume and the position of the tumour relative to the aortic arch. Regression modelling showed a reasonable predictive value for PET/CT in calculating EUS parameters, with r higher than 0.585 in some cases. CONCLUSION: Given the strong correlation between EUS and PET parameters, fluorine-18 fluorodeoxyglucose (F-FDG) PET can provide accurate information on the length and the volume of tumour in patients who either cannot tolerate EUS or have impassable strictures.	esophagus
Limited additional value of cervical ultrasonography over a negative 18F-FDG PET/CT for diagnosing cervical lymph node metastases in patients with esophageal cancer: a systematic review and meta-analysis.	OBJECTIVE: To assess the additional value of cervical ultrasonography as supplement to a negative fluorine-18-fluorodeoxyglucose (F-FDG) PET/computed tomography (CT) for detecting cervical lymph node metastases during the initial staging of patients with esophageal cancer. METHODS: PubMed/Medline, Embase, and the Cochrane library were systematically searched. The analysis included diagnostic studies describing the accuracy of cervical ultrasonography and integrated F-FDG PET/CT or standalone F-FDG PET and CT for detecting cervical lymph node metastases in patients with esophageal cancer. The reference standard consisted of cytopathology and/or clinical follow-up. The Quality Assessment of Diagnostic Accuracy Studies-2 tool was used to assess the quality of the included studies. A random effects model was used to meta-analyze the additional diagnostic value of cervical ultrasonography. RESULTS: Four diagnostic studies were eligible and included for meta-analysis, comprising 567 patients with esophageal cancer who underwent diagnostic workup before treatment. The quality of the included studies was considered reasonable; there were few concerns regarding risk of bias and applicability. In three of the four studies, cervical ultrasonography did not detect cervical lymph node metastases in addition to a negative finding on F-FDG PET/CT or standalone F-FDG PET and CT. In one study, cervical ultrasonography detected additional cervical lymph node metastases in 4% (3/74) of patients over standalone F-FDG PET and CT. Pooled estimate of the additional value of cervical ultrasonography was 1% (95% confidence interval: 0-5%). CONCLUSION: Cervical ultrasonography has very limited additional diagnostic value as supplement to a negative F-FDG PET/CT in the detection of cervical lymph node metastases during the initial staging of patients with esophageal cancer.	esophagus
Survival Implications of Increased Utilization of Local Excision for cT1N0 Esophageal Cancer.	OBJECTIVE: We hypothesized that patients with cT1N0 esophageal cancer undergoing local excision would have lower survival compared with esophagectomy due to potential discordant staging. BACKGROUND: Local excision has become an attractive alternative for management of early esophageal cancer, avoiding the morbidity of esophagectomy. It is uncertain if occult nodal metastasis impacts survival. METHODS: An observational study was conducted using the National Cancer Database (1998-2012) for patients with clinical T1N0 esophageal cancer who underwent local excision (n = 1625) or esophagectomy (n = 3255). RESULTS: The proportion of patients undergoing local excision increased from 12% in 1998 to 50% in 2012 (P < 0.001). After esophagectomy, 61% of cT1N0 cancers had concordant clinical and pathological staging, with 5.2% having positive nodal disease; 37% were staged concordant after local excision, with excess missing data (60%). Ninety-day mortality was 7.4% after esophagectomy compared with 2.8% after local excision (P < 0.001). While no significant difference was seen in unadjusted survival, adjusted Cox regression analysis indicated worse survival after esophagectomy compared with local excision for all cases [hazard ratio (HR) 1.57, 95% confidence interval (CI) 1.27-1.95] and for patients with concordant staging (HR 1.68, 95% CI 1.23-2.28). CONCLUSIONS: Local excision for cT1N0 esophageal cancer has increased over time. Contrary to our hypothesis, despite incomplete nodal staging, patients undergoing local excision have favorable survival, particularly in the adenocarcinoma subgroup. This may reflect early differences in mortality due to differences in procedure-related complications and/or selection bias. As this study has limited power to compare outcomes between T1a and T1b cancers, further analysis is warranted.	esophagus
Application of Computer-Aided Tongue Inspection for Preliminary Screening of Esophageal Cancer.	OBJECTIVE: To differentiate patients with esophageal cancer or premalignant lesions from the high-risk population for preliminary screening of esophageal cancer using a feature index determined by a computer-aided tongue information acquisition and processing system (DS01-B). METHODS: Totally, 213 patients diagnosed with esophageal cancer or premalignant lesions and 2,840 normal subjects were collected including primarily screened and reexamined, all of them were confirmed with histological examinations. Their tongue color space values and manifestation features were extracted by DS01-B and analyzed. Firstly, the analysis of variance was performed to differentiate normal subjects from patients with esophageal cancer and premalignant lesions. Secondly, the logistic regression was conducted using 10 features and gender, age to get a predictive equation of the possibility of esophageal cancer or premalignant lesions. Lastly, the equation was tested by subjects undergoing primary screening. RESULTS: Saturation (S) values in the HSV color space showed significant differences between patients with esophageal cancer and normal subjects or those with mild atypical hyperplasia (P<0.05); blue-to-yellow (b) values in the Lab color space showed significant differences between patients with esophageal cancer or premalignant lesions and normal subjects (P<0.05). Logistic regression analysis showed that the computer-aided tongue inspection approach had an accuracy of 72.3% (2008/2776) in identifying patients with esophageal cancer or premalignant lesions for preliminary screening in high-risk population. CONCLUSION: Computer-aided tongue inspection, with descriptive and quantitative profile as described in this study, could be applied as a cost- and timeefficient, non-invasive approach for preliminary screening of esophageal cancer in high-risk population.	esophagus
Defining pneumonia after esophagectomy for cancer: validation of the Uniform Pneumonia Score in a high volume center in North America.	Surgery is a central component of multimodality therapy for esophageal and gastroesophageal junction cancer. Pneumonia is a common sequela of esophagectomy, leading to an increase in intensive care unit stay, hospital stay, readmission rates, and postoperative mortality. Developing strategies to reduce pneumonia after esophagectomy is hampered by the absence of a standardized methodology for defining pneumonia. This study aims to validate the Uniform Pneumonia Score (UPS) in a high volume center in the USA. The UPS was developed to define pneumonia after esophagectomy for cancer and is based on the assessment of temperature (°C), leukocyte count (×109/L), and pulmonary radiography. The UPS has been validated utilizing a prospective, Institutional Review Board approved database of esophageal cancer patients treated in a high volume esophagectomy center in the USA between 2010 and 2015. One hundred ninety-three consecutive patients were included and 21 (10.9%) were treated for pneumonia. The UPS was able to predict treatment for suspected pneumonia with a good sensitivity (85.7%, confidence interval (CI): 63.7%-96.7%), specificity (97.1%, CI: 93.4%-99.1%), positive predictive value (78.3%, CI: 59.9%-89.7%), and negative predictive value (98.2%, CI: 95.1%-99.4%). The diagnostic accuracy was 95.9%, CI: 92.0%-98.2%. The UPS demonstrated to be a reliable scoring system to define pneumonia after esophagectomy for cancer. Global application of this model will standardize the definition of pneumonia after esophagectomy. This will improve outcome reporting and comparisons of complications between individual institutions, clinical trials, and national audits.	esophagus
Aberrant methylation of EYA4 promotes epithelial-mesenchymal transition in esophageal squamous cell carcinoma.	EYA4, one of the four members of the EYA gene family, is associated with several human cancers. However, its biological functions and molecular mechanisms in the progression of cancer, particularly in esophageal squamous cell carcinoma (ESCC), remain unknown. In the present study, we found that EYA4 was underexpressed and hypermethylated in most of the ESCC cell lines tested (85.7%, 6/7). Treatment with 5-aza-dC and/or trichostatin A (TSA) restored EYA4 expression in ESCC cell lines, which indicates that EYA4 expression was epigenetically regulated. Similarly, EYA4 was aberrantly hypermethylated in ESCC tissues (78%, 39/50) and downregulation of EYA4 occurred in approximately 65% of primary ESCC at protein level where it was associated significantly with TNM stage and lymph node metastases. Knockdown of EYA4 in KYSE30 and KYSE70 ESCC cells using small hairpin RNA increased migration and invasive motility in vitro. Conversely, the overexpression of EYA4 in KYSE180 and KYSE450 promoted an epithelial phenotype, which consisted of decreased migration and invasion abilities and a decrease in TGF-β1-induced epithelial-mesenchymal transition. Mechanistically, EYA4 overexpression reduced the phosphorylation of Akt and glycogen synthase kinase (GSK) 3β, which led to the inactivation of slug. In addition, we found that TGF-β1 decreased EYA4 expression in both a dose-dependent and a time-dependent manner in KYSE30 cells, accompanied by an increase in the expression of DNA methyltransferases, especially DNMT3A. In summary, EYA4 is frequently hypermethylated in ESCC and may function as a tumor suppressor gene in the development of ESCC.	esophagus
Risk factors for pericardial effusion after chemoradiotherapy for thoracic esophageal cancer-comparison of four-field technique and traditional two opposed fields technique.	Pericardial effusion is an important late toxicity after concurrent chemoradiotherapy (CCRT) for locally advanced esophageal cancer. We investigated the clinical and dosimetric factors that were related to pericardial effusion among patients with thoracic esophageal cancer who were treated with definitive CCRT using the two opposed fields technique (TFT) or the four-field technique (FFT), as well as the effectiveness of FFT. During 2007-2015, 169 patients with middle and/or lower thoracic esophageal cancer received definitive CCRT, and 94 patients were evaluable (51 FFT cases and 43 TFT cases). Pericardial effusion was observed in 74 patients (79%) and appeared at 1-18.5 months (median: 5.25 months) after CCRT. The 1-year incidences of pericardial effusions were 73.2% and 76.7% in the FFT and TFT groups, respectively (P = 0.6395). The mean doses to the pericardium were 28.6 Gy and 31.8 Gy in the FFT and TFT groups, respectively (P = 0.0259), and the V40 Gy proportions were 33.5% and 48.2% in the FFT and TFT groups, respectively (P < 0.0001). Grade 3 pericardial effusion was not observed in patients with a pericardial V40 Gy of <40%, or in patients who were treated using the FFT. Although the mean pericardial dose and V40 Gy in the FFT group were smaller than those in the TFT group, the incidences of pericardial effusion after CCRT were similar in both groups. As symptomatic pericardial effusion was not observed in patients with a pericardial V40 Gy of <40% or in the FFT group, it appears that FFT with a V40 Gy of <40% could help minimize symptomatic pericardial effusion.	esophagus
[Endoscopic trans-fistula drainage for gastroesophageal anastomotic fistula with para-fistula abscess after esophagectomy].	Objective: To evaluate the efficiency and safety of endoscopic trans-fistula drainage (ETFD) for gastroesophageal anastomotic fistula with para-fistula abscess after esophagectomy. Methods: Among 456 esophageal cancer patients receiving esophagectomy between February 2012 and February 2017 in Sir Run Run Shaw Hospital, 15 cases were diagnosed as gastroesophageal anastomotic fistula with para-fistula abscess after surgery. Seven cases received ETFD treatment (ETFD group), and 8 cases received conventional treatment (control group). Recovery of inflammatory markers and fistula, length of hospital stay after esophagectomy and total medical expenses were compared between ETFD group and control group. Results: All patients recovered in ETFD group. Time of white cell count returning to normal and decline of C-reactive protein, time of fistula healing and length of hospital stay after esophagectomy in ETFD group were significantly shorter than those of control group (all P<0.05). And medical expenses in ETFD group was also lower (P<0.05). Conclusion: ETFD is effective and safe for gastroesophageal anastomotic fistula with para-fistula abscess after esophagectomy.	esophagus
TSPAN15 interacts with BTRC to promote oesophageal squamous cell carcinoma metastasis via activating NF-κB signaling.	Beta-transducin repeat containing E3 ubiquitin protein ligase (BTRC) is crucial for the degradation of IκBα. Our previous transcriptome sequencing analysis revealed that tetraspanin 15 (TSPAN15) was significantly upregulated in clinical oesophageal squamous cell carcinoma (OSCC) tissues. Here, we show that high TSPAN15 expression in OSCC tissues is significantly associated with lymph node and distant metastasis, advanced clinical stage, and poor prognosis. Elevated TSPAN15 expression is, in part, caused by the reduction of miR-339-5p. Functional studies demonstrate that TSPAN15 promotes metastatic capabilities of OSCC cells. We further show that TSPAN15 specifically interacts with BTRC to promote the ubiquitination and proteasomal degradation of p-IκBα, and thereby triggers NF-κB nuclear translocation and subsequent activation of transcription of several metastasis-related genes, including ICAM1, VCAM1, uPA, MMP9, TNFα, and CCL2. Collectively, our findings indicate that TSPAN15 may serve as a new biomarker and/or provide a novel therapeutic target to OSCC patients.	esophagus
DCE-MRI-Derived Volume Transfer Constant (K(trans)) and DWI Apparent Diffusion Coefficient as Predictive Markers of Short- and Long-Term Efficacy of Chemoradiotherapy in Patients With Esophageal Cancer.	This study aimed to evaluate both the short- and long-term efficacies of chemoradiotherapy in relation to the treatment of esophageal cancer . This was achieved through the use of dynamic contrast-enhanced magnetic resonance imaging-derived volume transfer constant and diffusion weighted imaging-derived apparent diffusion coefficient . Patients with esophageal cancer were assigned into the sensitive and resistant groups based on respective efficacies in chemoradiotherapy. Dynamic contrast-enhanced magnetic resonance imaging and diffusion weighted imaging were used to measure volume transfer constant and apparent diffusion coefficient, while computed tomography was used to calculate tumor size reduction rate. Pearson correlation analyses were conducted to analyze correlation between volume transfer constant, apparent diffusion coefficient, and the tumor size reduction rate. Receiver operating characteristic curve was constructed to analyze the short-term efficacy of volume transfer constant and apparent diffusion coefficient, while Kaplan-Meier curve was employed for survival rate analysis. Cox proportional hazard model was used for the risk factors for prognosis of patients with esophageal cancer. Our results indicated reduced levels of volume transfer constant, while increased levels were observed in ADC(min), ADC(mean), and ADC(max) following chemoradiotherapy. A negative correlation was determined between ADC(min), ADC(mean), and ADC(max), as well as in the tumor size reduction rate prior to chemoradiotherapy, whereas a positive correlation was uncovered postchemoradiotherapy. Volume transfer constant was positively correlated with tumor size reduction rate both before and after chemoradiotherapy. The 5-year survival rate of patients with esophageal cancer having high ADC(min), ADC(mean), and ADC(max) and volume transfer constant before chemoradiotherapy was greater than those with respectively lower values. According to the Cox proportional hazard model, ADC(mean), clinical stage, degree of differentiation, and tumor stage were all confirmed as being independent risk factors in regard to the prognosis of patients with EC. The findings of this study provide evidence suggesting that volume transfer constant and apparent diffusion coefficient as being tools allowing for the evaluation of both the short- and long-term efficacies of chemoradiotherapy esophageal cancer treatment.	esophagus
Comparative study of computed tomography (CT) and pathological diagnosis toward mediastinal lymph node metastasis in esophageal carcinoma.	OBJECTIVE: To investigate the diagnostic criteria of mediastinal lymph node metastasis (MLNM) in esophageal carcinoma (EC) by comparing the lymph node sizes measured by computed tomography (CT) and obtained by postoperative pathological examination. METHOD: A total of 305 EC patients were selected. MLNM location, shortest diameter and number were investigated one week before surgery, and then compared with their pathological findings. RESULTS: The receiver operating characteristic (ROC) curve analysis revealed that the minimum diameters of MLNM in the thoracic cavity was 8 mm (area under curve [AUC] = 0.766, Youden index = 0.424), 5 mm in supraclavicular fossa (AUC = 0.785, Youden index = 0.494), 6 mm in tracheoesophageal groove (AUC = 0.755, Youden index = 0.405); the sensitivity was increased significantly, and the Youden index was increased significantly when compared with 10 mm. CONCLUSION: The shortest diameter of diagnostic criteria of lymph nodes in EC could be less than 10 mm on CT.	esophagus
Validation of a biomarker panel in Barrett's esophagus to predict progression to esophageal adenocarcinoma.	In a prior study, baseline mutational load (ML) predicted progression to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) in Barrett's esophagus (BE) with an area under the curve (AUC) of 0.95. We aimed to validate the test characteristics of this predictive biomarker panel using crude DNA lysates in a larger well-characterized cohort. We performed a nested case-control study of BE patients from three tertiary referral centers in the Netherlands. Cases had baseline nondysplastic BE (NDBE) and developed HGD/EAC ≥ 2 years later. Controls were matched 2:1, had baseline NDBE, and no progression. Polymerase chain reaction (PCR)-based mutational analysis was performed on crude lysates from formalin-fixed, paraffin-embedded tissue. ML was calculated from loss of heterozygosity (LOH) and microsatellite instability (MSI) at 10 genomic loci. Receiver operator characteristic (ROC) curves were created to assess the diagnostic utility of various cutoffs of ML for progression. Of 159 subjects, 58 were progressors and 101 were nonprogressors, there was no difference in mean ML in preprogression tissue in progressors and nonprogressors (ML = 0.73 ± 0.69 vs. ML = 0.74 ± 0.61, P = 0.93). ROC curves showed poor discrimination of ML in predicting progression with AUC of 0.50 at ML ≥ 1. AUC did not vary with different ML cut-points. The utility of the ML to stratify BE patients for risk of progression was not confirmed in this study. The etiology for discrepancies between this and prior studies showing high predictiveness is likely due to the use of crude lysates in this study, but requires further investigation.	esophagus
Exploring the microbiota to better understand gastrointestinal cancers physiology.	Gastrointestinal cancers account for around 40% of cancer-related deaths worldwide, representing a global health burden. There is a growing body of evidence highlighting the link between microbiota and gastrointestinal tumorigenesis and/or resistance to therapy. In the present manuscript, we reviewed the published studies on the relationship between the microbiota and the different gastrointestinal tumors, namely, gastric, colorectal and esophageal, including also the cancer of accessory organs such as liver and pancreas. There is an emergent interest in the manipulation of gastrointestinal microflora in order to understand the gastrointestinal tumorigenesis' processes and the establishment of chemoresistance mechanisms.	esophagus
