Patterns of care and clinical outcomes in primary oesophageal gastrointestinal stromal tumours (GIST): A retrospective study of the French Sarcoma Group (FSG).	BACKGROUND: Oesophageal GIST (ESOGIST) are very rare tumours requiring special consideration regarding diagnosis, surgical management, and perioperative treatment. METHODS: A retrospective study was conducted across 9 centres in the French Sarcoma Group (FSG) to characterize all patients in the years 2000-2014. RESULTS: Seventeen patients (pts) with primary localized ESOGIST were identified, with median age 69 years (36-81) and 11 females. Eight tumours (T) occurred in the lower third of the oesophagus, five in the oesophageal gastric junction, two in the superior third, and two in the middle third. All pts underwent oesophagoscopy and/or endoscopic ultrasound (EUS) and CT scan. Fifteen had EUS guided biopsy. Nine pts received Imatinib (IM) as initial treatment resulting in six PR, three SD. Tumours were resected in nine pts (53%) (7 upfront, 2 after IM); via enucleation in four (44%) [median size 4 cm], oesophagectomy in five (56%) [median size 10 cm]. Resections were R0 in three pts (33%), R1 in six (66%). Eight pts (47%) had no tumour resection, and one patient was never treated. Six pts received adjuvant IM. With a median follow-up of 24 months (7-101), 11 pts are alive (64.7%), five died (29.4%), one was lost to follow-up. Two pts of 4 pts relapsed following enucleation. CONCLUSIONS: ESOGIST can be reliably identified pre-operatively by EUS-guided biopsy. Surgery for ESOGIST is either enucleation or oesophagectomy depending on tumour size, location, and patient's individual surgical risk. Preoperative IM therapy could improve resectability and should be considered if surgery is contraindicated or would lead to negative impact on the functional status of the patient.	esophagus
The Society of Thoracic Surgeons General Thoracic Surgery Database 2017 Update on Outcomes and Quality.	The Society of Thoracic Surgeons General Thoracic Surgery Database (STS GTSD) is a voluntary effort that provides participants with risk-adjusted semiannual performance reports that allow comparison of institutional outcomes against national benchmarks. With nearly 1,000 surgeons contributing data from more than 300 centers across North America, the STS GTSD now includes almost a half million cases. In 2016, updated risk models for lung resection and esophagectomy for cancer were reported, and composite quality measures for lobectomy and esophagectomy were developed. Ongoing efforts include upgrading the STS GTSD, establishing public reporting of lobectomy for lung cancer composite scores, creating an on-line dashboard, and strengthening international collaboration with the European Society of Thoracic Surgery Registry. With these initiatives, the STS GTSD aims to continue to improve quality of care and support research endeavors in general thoracic surgery. This article summarizes current aggregate national outcomes in general thoracic surgery and reviews related activities in the areas of quality measurement, performance improvement, and transparency from the STS GTSD during the past 12 months.	esophagus
Treatment of esophageal cancer with radiation therapy -a pan-Chinese survey of radiation oncologists.	Lots of controversies were found about the treatment in relation to radiation therapy (RT) for esophageal squamous cell carcinoma (ESCC). We designed a questionnaire of these controversies to do a pan-Chinese survey of radiation oncologists (ROs). For operable ESCC, 53% ROs chose surgery plus postoperative chemoradiotherapy (CRT), while 40% chose preoperative CRT plus surgery. For target volume of postoperative RT, most ROs (92%) would delineate tumor bed plus involved lymph nodes region before surgery. For definitive RT, most ROs (81%) would give patients higher RT dose to 60-65Gy. For radiation target volume, most ROs would give patients prophylactic irradiation of the bilateral superclavicular-lymph nodes region for cervical ESCC (93%), and the left gastric lymph nodes region for lower thoracic ESCC (72%). For the treatment of mediastinal lymph nodes, 72% ROs preferred elective nodal irradiation, while 28% did the involved nodal irradiation. For concurrent chemotherapy regimen, PF (5-Fu + cisplatin) and TP (cisplatin + paclitaxel) were used widely (49% and 46%, respectively). During simulation, four-dimensional computer tomography (4D CT) was not widely used (48%), even for cervical or lower thoracic ESCC (52%). For daily RT delivery, only 66% ROs would perform imaging guidance RT daily. In summary, more controversies existed in the treatment of ESCC with RT in China, including treatment strategy, radiation dose and target contour. Future goals include standardization of treatment strategy, radiation dose, and target contour, and application of 4D CT and daily imaging guidance, and pursuit of randomized trials in Chinese population.	esophagus
Expression of Programmed Cell Death Protein 1 by Tumor-Infiltrating Lymphocytes and Tumor Cells is Associated with Advanced Tumor Stage in Patients with Esophageal Adenocarcinoma.	BACKGROUND: Despite recent advances in the therapy for adenocarcinoma of the esophagogastric junction (AEG), overall prognosis remains poor. Programmed cell death protein 1 (PD1) is a co-inhibitory receptor primarily expressed by T-cells. Tumor cells can escape anticancer immune responses by triggering the PD1 pathway. Moreover, PD1 receptor engagement on cancer cells may trigger tumor-intrinsic growth signals. This study aimed to evaluate the potential clinical relevance of PD1 expression by tumor-infiltrating lymphocytes (TILs) and cancer cells in the AEG. METHODS: Patients with AEG who underwent esophagectomy from 1992 to 2011 were included in the study. Expression of PD1was evaluated by immunohistochemistry and correlated with long-term overall survival (OS), disease-free survival (DFS), and various clinicopathologic parameters. RESULTS: Tumor biospecimens from 168 patients were analyzed. In the analysis, 81% of the patients showed high tumoral frequencies (>5%) of PD1-expressing TILs (TIL-PD1(+)), and 77% of patient tumors harbored high levels (>5%) of PD1(+) cancer cells (cancer-PD1(+)). Expression of PD1 by TILs and cancer cells correlated significantly (p < 0.05) with patients' tumor stage and lymph node involvement. Compared with the patients who had low tumoral frequencies of PD1(+) TILs or cancer cells, the TIL-PD1(+) and cancer-PD1(+) patients demonstrated significantly reduced DFS in the univariate analysis (5-year DFS: 73.3 vs. 41.9%, log-rank 0.008 and 71.3 vs. 41.6%, p = 0.008, respectively). Additionally, the cancer-PD1(+) patients showed significantly decreased OS in the univariate analysis compared with the cancer-PD1(-) patients (5-year OS: 68.8 vs. 43.5%; p = 0.047). However, these correlations did not reach significance in the multivariate analysis. CONCLUSIONS: The PD1 receptor is expressed by both TILs and cancer cells in AEG. High expression of PD1 is associated with advanced tumor stage and lymph node involvement, but not with survival.	esophagus
Inhibition of glutathione metabolism attenuates esophageal cancer progression.	Esophageal squamous cell carcinoma (ESCC) is a deadly malignancy with regard to mortality and prognosis, and the 5-year survival rate for all patients diagnosed with ESCC remains poor. A better understanding of the biological mechanisms of ESCC tumorigenesis and progression is of great importance to improve treatment of this disease. In this study, we demonstrated that the glutathione metabolism pathway is highly enriched in ESCC cells compared with normal esophageal epithelial cells in an in vivo mouse model. In addition, treatment with L-buthionine-sulfoximine (BSO) to deplete glutathione decreased the ESCC tumor burden in mice, thus demonstrating the critical role of glutathione metabolism in ESCC progression. BSO treatment also led to decreased cell proliferation and activation of cell apoptosis in ESCC. Finally, BSO treatment blocked NF-kB pathway activation in ESCC. Our study reveals a new pathway that regulates ESCC progression and suggests that inhibition of glutathione metabolism may be a potential strategy for ESCC treatment.	esophagus
GALNT14 genotype as a response predictor for concurrent chemoradiotherapy in advanced esophageal squamous cell carcinoma.	"Esophageal squamous cell carcinoma is an aggressive cancer. We investigated genetic response predictors for patients with advanced esophageal squamous cell carcinoma receiving concurrent chemoradiotherapy. A cohort of 108 patients was recruited. Survival analysis showed that lower esophageal location of tumor, more advanced metastasis stage, and longer length of tumor were associated with poorer overall survival (adjusted P = 0.001, < 0.001, and 0.045, respectively), while the presence of complete/partial response to concurrent chemoradiotherapy was independently associated with better overall survival (adjusted P < 0.001). The GALNT14-rs9679162 ""GG"" genotype was associated with a lower rate of response (P = 0.014). Multivariate Cox-proportional hazards models also showed that the ""GG"" genotype was associated with a longer time to complete/partial response (adjusted P = 0.022), independent of leukocyte counts and gender. In conclusion, the presence of a complete/partial response to chemoradiotherapy was critical for advanced esophageal squamous cell carcinoma patients to achieve better overall survival. The GALNT14-rs9679162 ""GG"" genotype was associated with a longer time to complete/partial response of concurrent chemoradiotherapy."	esophagus
The urokinase plasminogen activation system in gastroesophageal cancer: A systematic review and meta-analysis.	BACKGROUND: The urokinase plasminogen activation (uPA) system is a crucial pathway for tumour invasion and establishment of metastasis. Although there is good evidence that uPA system expression is a clinically relevant biomarker in some solid tumours, its role in gastroesophageal cancer is uncertain. RESULTS: We identified 22 studies encompassing 1966 patients which fulfilled the inclusion criteria. uPA, uPAR, or PAI-1 expression is significantly associated with high risk clinicopathological features. High uPA expression is associated with a shorter RFS (HR 1.90 95% 1.16-3.11, p = 0.01) and OS (HR 2.21 95% CI 1.74-2.80, p < 0.0001). High uPAR expression is associated with poorer OS (HR 2.21 95%CI 1.82-2.69, p < 0.0001). High PAI-1 expression is associated with shorter RFS (HR 1.96 96% CI 1.07-3.58, p = 0.03) and OS (HR 1.84 95%CI 1.28-2.64, p < 0.0001). There was no significant association between PAI-2 expression and OS (HR 0.97 95%CI 0.48-1.94, p < 0.92) although data was limited. MATERIALS AND METHODS: We undertook a systematic review evaluating expression of uPA, urokinase plasminogen activator receptor (uPAR), plasminogen activator inhibitor-1 (PAI-1/SerpinE1) and plasminogen activator inhibitor-2 (PAI-2/SerpinB2) on primary oesophageal, gastro-oesophageal junction, and gastric adenocarcinomas. We performed a meta-analysis of clinicopathological associations, overall survival (OS) and recurrence free survival (RFS). CONCLUSIONS: We conclude that the uPA system is a clinically relevant biomarker in primary gastroesophageal cancer, with higher expression of uPA, uPAR and PAI-1 associated with higher risk disease and poorer prognosis. This also highlights the potential utility of the uPA system as a therapeutic target for improved treatment strategies.	esophagus
Oesophageal cancer presenting as Lemierre's syndrome caused by Streptococcus anginosus.	A 59-year-old man presented to the emergency department with complaints of dysphagia, right-sided neck swelling, fever and chills. Physical examination was remarkable for fever and tender swelling over the right side of the neck. Laboratory investigations revealed leucocytosis with neutrophilia. CT of the neck showed right internal jugular vein thrombosis with an overlying abscess and a nodular opacity in the right lung apex with air locules. He underwent surgical drainage of the neck abscess. Aerobic cultures from the drainage and blood cultures grew Streptococcus anginosus Given his initial complaint of dysphagia, upper endoscopy was performed which showed a mass in the upper oesophagus. Histopathology confirmed squamous cell carcinoma. The patient received 6 weeks of antibiotics therapy.	esophagus
Tyrosine kinase inhibitor induced growth factor receptor upregulation enhances the efficacy of near-infrared targeted photodynamic therapy in esophageal adenocarcinoma cell lines.	Esophageal carcinoma (EC) is a global health problem, with disappointing 5-year survival rates of only 15-25%. Near-infrared targeted photodynamic therapy (NIR-tPDT) is a novel strategy in which cancer-targeted phototoxicity is able to selectively treat malignant cells. In this in vitro report we demonstrate the applicability of antibody-based NIR-tPDT in esophageal adenocarcinoma (EAC), using the phototoxic compounds cetuximab-IRDye700DX and trastuzumab-IRDye700DX, targeting respectively epidermal growth factor receptor 1 (EGFR) and 2 (HER2). Furthermore, we demonstrate that NIR-tPDT can be made more effective by tyrosine kinase inhibitor (TKI) induced growth receptor upregulation. Together, these results unveil a novel strategy for non-invasive EAC treatment, and by pretreatment-induced receptor upregulation its future clinical application may be optimized.	esophagus
Identification of molecular targets for esophageal carcinoma diagnosis using miRNA-seq and RNA-seq data from The Cancer Genome Atlas: a study of 187 cases.	Esophageal carcinoma (ESCA) is one of the most common malignancies worldwide, and its pathogenesis is complex. In this study, we identified differentially expressed miRNAs (DEMs) and genes (DEGs) of ESCA from The Cancer Genome Atlas (TCGA) database. The diagnostic values of DEMs were determined by receiver operating characteristic (ROC) analyses and validated based on data from Gene Expression Omnibus (GEO). The top five DEMs with the best diagnostic values were selected, and their potential targets were predicted by various in silico methods. These target genes were then identified among the DEGs from TCGA. Furthermore, the overlapping genes were subjected to protein-protein interaction (PPI) analysis, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses. The miRNA-transcription factor (TF) regulatory relations were determined using CircuitsDB and TransmiR. Finally, the regulatory networks of miRNA-TF and miRNA-gene were constructed and analyzed. A total of 136 DEMs and 3541 DEGs were identified in ESCA. The top five DEMs with the highest area under the receiver operating characteristic curve (AUC) values were miRNA-93 (0.953), miRNA-21 (0.928), miRNA-4746 (0.915), miRNA-196a-1 (0.906) and miRNA-196a-2 (0.906). The combined AUC of these five DEMs was 0.985. The KEGG analysis with 349 overlapping genes showed that the calcium signaling pathway and the neuroactive ligand-receptor interaction were the most relevant pathways. The regulatory networks of miRNA-TF and miRNA-gene, including 38 miRNA-TF and 560 miRNA-gene pairs, were successfully established. Our findings may provide new insights into the molecular mechanisms of ESCA pathogenesis. Future research will aim to explore the role of novel miRNAs in the pathogenesis and improve the early diagnosis of ESCA.	esophagus
Volume-outcome relation in palliative systemic treatment of metastatic oesophagogastric cancer.	INTRODUCTION: Palliative systemic therapy has been shown to improve survival in metastatic oesophagogastric cancer. Administration of palliative systemic therapy in metastatic oesophagogastric cancer varies between hospitals. We aimed to explore the association between the annual hospital volume of oesophagogastric cancer patients and survival. METHODS: Patients diagnosed in the Netherlands between 2005 and 2013 with metastatic oesophagogastric cancer were identified in the Netherlands Cancer Registry. Patients were attributed according to three definitions of high volume: (1) high-volume incidence centre, (2) high-volume treatment centre and (3) high-volume surgical centre. Independent predictors for administration of palliative chemotherapy were evaluated by means of multivariable logistic regression analysis, and multivariable Cox proportional hazard regression analysis was performed to assess the impact of high-volume centres on survival. RESULTS: Our data set comprised 4078 patients with metastatic oesophageal cancer, and 5425 patients with metastatic gastric cancer, with a median overall survival of 20 weeks (95% confidence interval [CI] 19-21 weeks) and 16 weeks (95% CI 15-17 weeks), respectively. Patients with oesophageal cancer treated in a high-volume surgical centre (adjusted hazard ratio [HR] 0.80, 95% CI 0.70-0.91) and a high-volume treatment centre (adjusted HR 0.88, 95% CI 0.78-0.99) exhibited a decreased risk of death. For gastric cancer, patients treated in a high-volume surgical centre (adjusted HR 0.83, 95% CI 0.74-0.92) had a superior outcome. CONCLUSION: Improved survival in patients undergoing palliative systemic therapy for oesophagogastric cancer was associated with treatment in high-volume treatment and surgical centres. Further research should be implemented to explore which specific factors of high-volume centres are associated with improved outcomes.	esophagus
Socioeconomic Status, Not Race, Is Associated With Reduced Survival in Esophagectomy Patients.	BACKGROUND: Black patients with esophageal cancer have worse survival than white patients. This study examines this racial disparity in conjunction with socioeconomic status (SES) and explores whether race-based outcome differences exist using a national database. METHODS: The associations between race and SES with overall survival of patients treated with esophagectomy for stages I to III esophageal cancer between 2003 and 2011 in the National Cancer Data Base were investigated using the Kaplan-Meier method and proportional hazards analyses. Median income by zip code and proportion of the zip code residents without a high school diploma were grouped into income and education quartiles, respectively and used as surrogates for SES. The association between race and overall survival stratified by SES is explored. RESULTS: Of 11,599 esophagectomy patients who met study criteria, 3,503 (30.2%) were in the highest income quartile, 2,847 (24.5%) were in the highest education quartile, and 610 patients (5%) were black. Before adjustment for SES, black patients had worse overall survival than white patients (median survival 23.0 versus 34.7 months, log rank p < 0.001), and overall, survival times improved with increasing income and education (p < 0.001 for both). After adjustment for putative prognostic factors, SES was associated with overall survival, whereas race was not. CONCLUSIONS: Prior studies have suggested that survival of esophageal cancer patients after esophagectomy is associated with race. Our study suggests that race is not significantly related to overall survival when adjusted for other prognostic variables. Socioeconomic status, however, remains significantly related to overall survival in our model.	esophagus
Influence of Tanshinone IIA on apoptosis of human esophageal carcinoma Eca-109 cells and its molecular mechanism.	BACKGROUND: Previous studies have shown that Tanshinone (Tan) IIA exerts obvious antitumor efficacy; however, its molecular mechanism remains unclear. This study was conducted to identify the influence of Tan IIA on Eca-109 cell apoptosis, explore its molecular mechanism, and provide a theoretical basis for clinical application. METHODS: Eca-109 cells were cultured in vitro and treated with different concentrations of Tan IIA. Morphologic changes were viewed under inverted fluorescence microscope with dual acridine orange/ethidium bromide staining assay. Methyl-thiazolyl-tetrazolium and Annexin V propidium iodide assays were respectively used to measure cell viability and apoptosis rate. The protein and messenger (m)RNA expression of binding immunoglobulin protein (BIP), mitochondrial cytochrome c (CytC), and caspase-9 were detected by Western blot and quantitative real-time PCR, respectively. RESULTS: Cell viability decreased and the apoptosis rate significantly increased with increasing concentrations of Tan IIA (0, 20, 40, 60 μg/mL), which indicated that Tan IIA inhibited the proliferation and induced the apoptosis of Eca-109 cells in a dose-dependent manner. Eca-109 cells treated with 60 μg/mLTan IIA showed typical morphological changes of apoptosis under the inverted microscope. Moreover, compared with the negative control group, protein and mRNA expression of BIP decreased significantly (P < 0.05), whereas protein and mRNA expression of CytC and caspase-9 increased significantly (P < 0.05). CONCLUSION: Tan IIA can induce apoptosis in human esophageal carcinoma Eca-109 cells by regulating BIP, CytC, and caspase-9 expression. Endoplasmic reticulum stress and mitochondrial-dependent may be involved in Tan IIA-induced Eca-109 cell apoptosis.	esophagus
Preoperative serum lipids as prognostic predictors in esophageal squamous cell carcinoma patients with esophagectomy.	This study was to evaluate the prognostic significance of serum lipids in esophageal squamous cell carcinoma patients who underwent esophagectomy. Preoperative serum lipids were collected from 214 patients who were diagnosed with esophageal squamous cell carcinoma. All of the patients received esophagectomy in Qilu Hospital of Shandong University from January 2007 to December 2008. The records and data were analyzed retrospectively. We found that low total cholesterol (for T stage, p = 0.006; for TNM stage, p = 0.039) and low-density lipoprotein cholesterol (for T stage, p = 0.031; for TNM stage, p = 0.035) were associated with advanced T stage and TNM stage. Kaplan-Meier survival analysis indicated that low total cholesterol and low-density lipoprotein cholesterol were associated with shorter disease-free survival(for total cholesterol, p = 0.045; for low-density lipoprotein cholesterol, p < 0.001) and overall survival (for total cholesterol, p = 0.043; for low-density lipoprotein cholesterol, p < 0.001). Lower low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio (LHR) indicated poorer disease-free survival and overall survival (both p < 0.001). In the multivariate analysis, low-density lipoprotein cholesterol and LHR were independent prognostic factors for disease-free survival and overall survival. In conclusion, our study indicated that preoperative serum total cholesterol and low-density lipoprotein cholesterol are prognostic factors for esophageal squamous cell carcinoma patients who underwent esophagectomy. LHR can serve as a promising serum lipids-based prognostic indicator.	esophagus
