Deubiquitylatinase inhibitor b-AP15 induces c-Myc-Noxa-mediated apoptosis in esophageal squamous cell carcinoma.	Esophageal squamous cell carcinoma (ESCC) is one of the most malignant tumors in east Asia. However, the molecular mechanism underlying its progression remains unclear. The ubiquitin-proteasome system (UPS) is a central mechanism for protein degradation and turnover. Accumulating evidence showed that more and more deubiquitinases could serve as attractive anti-cancer target. The expression of USP14 and UCH37 in esophagus squamous cell carcinoma tissues were examined by immunohistochemistry and western blot assays. Effect of b-AP15, a USP14 and UCH37 inhibitor, on ESCC cell growth was evaluated by cell viability assay. After cell lines being treated with b-AP15, cell cycle, apoptosis and the expression of related proteins were further explored to investigate the anti-ESCC mechanism of b-AP15. Results showed that deubiquitinating enzymes (DUBs) USP14 and UCH37 expressed at higher levels in ESCC tissues than in adjacent tissues. b-AP15 could inhibit cell proliferation and induce G2/M cell cycle arrest and apoptosis in ESCC cells. Mechanistically, b-AP15 treatment triggered Noxa-dependent apoptosis, which was regulated by c-Myc. Silencing Noxa and c-Myc could reduce b-AP15-induced apoptosis in ESCC cells. Our results revealed a novel mechanism of anti-tumor activity of b-AP15 in ESCC, and b-AP15 could be used as a potential therapeutic agent in ESCC.	esophagus
Risk factors for febrile neutropenia in neoadjuvant docetaxel, cisplatin, and 5-fluorouracil chemotherapy for esophageal cancer.	PURPOSE: The aim of the present study was to evaluate the incidence and explore the risk factors of febrile neutropenia (FN) in patients with esophageal cancer receiving neoadjuvant docetaxel, cisplatin, and 5-fluorouracil (DCF) chemotherapy in real-world settings. METHODS: We retrospectively reviewed clinical data of 128 consecutive patients with esophageal cancer. Specifically, these patients underwent neoadjuvant DCF chemotherapy with prophylactic antibiotic administration at our institution between July 2009 and January 2015. Two FN-related endpoints were set as follows: definite FN (dFN) defined as grade 4 neutropenia at the onset of fever and clinically suspected FN (csFN), which included both patients with dFN and patients without grade 4 neutropenia but with deteriorating grade 3 neutropenia at the onset of fever who were clinically diagnosed with FN for which they underwent treatment. The risk factors for dFN and csFN were evaluated based on patients' characteristics. RESULTS: A total of 72 (56.3%) patients developed grade 3 or grade 4 neutropenia and 26 (20.3%) developed csFN including 14 (10.9%) with dFN. Multivariate analysis revealed that older age (OR 3.57, CI 1.27-10.1, P = 0.016) and living alone (OR 5.17, 95% CI 1.26-21.3, P = 0.023) were statistically significant risk factors for csFN development. As to dFN, no statistically significant risk factors were identified. CONCLUSIONS: Older age and living alone are significant risk factors for developing FN, and thus, particularly for patients with risk factors for FN, G-CSF should be considered instead of prophylactic antibiotics with careful observation.	esophagus
Risk factors associated with increased drainage volumes of chest tubes after transthoracic esophagectomy for esophageal cancer.	PURPOSE: Prolonged chest drain placement can extend the postoperative hospital stay after esophagectomy in esophageal cancer (EC) patients. This study aimed to identify whether or not the risk factors associated with this prolonged chest tube placement are clinically important. METHODS: A total of 138 patients who underwent subtotal esophagectomy for thoracic EC were retrospectively analyzed. Using the 75th percentile of the total drainage volume of chest tubes as a cutoff value, the high-output (HO; n = 35) and low-output (LO; n = 103) groups were compared in terms of the clinicopathological parameters. RESULTS: The median durations of right and left chest tube placement were 6 and 9 days, respectively, with a median total drainage volume of 2692 ml. When compared with the LO group, the HO group was significantly associated with male gender, a subcutaneous route for reconstruction, blood transfusion, higher morbidity, and prolonged chest drainage and postoperative hospital stays. A multivariable analysis further identified blood loss (p = 0.03) and the subcutaneous route for reconstruction (p = 0.04) as independent risk factors for increased chest tube drainage after esophagectomy. CONCLUSION: Blood loss and the subcutaneous route of reconstruction are risk factors for increased drainage of chest tube after esophagectomy for EC.	esophagus
Heterogeneity of first-line palliative systemic treatment in synchronous metastatic esophagogastric cancer patients: A real-world evidence study.	The optimal first-line palliative systemic treatment strategy for metastatic esophagogastric cancer is not well defined. The aim of our study was to explore real-world use of first-line systemic treatment in esophagogastric cancer and assess the effect of treatment strategy on overall survival (OS), time to failure (TTF) of first-line treatment and toxicity. We selected synchronous metastatic esophagogastric cancer patients treated with systemic therapy (2010-2016) from the nationwide Netherlands Cancer Registry (n = 2,204). Systemic treatment strategies were divided into monotherapy, doublet and triplet chemotherapy, and trastuzumab-containing regimens. Data on OS were available for all patients, on TTF for patients diagnosed from 2010 to 2015 (n = 1,700), and on toxicity for patients diagnosed from 2010 to 2014 (n = 1,221). OS and TTF were analyzed using multivariable Cox regression, with adjustment for relevant tumor and patient characteristics. Up to 45 different systemic treatment regimens were found to be administered, with a median TTF of 4.6 and OS of 7.5 months. Most patients (45%) were treated with doublet chemotherapy; 34% received triplets, 10% monotherapy and 10% a trastuzumab-containing regimen. The highest median OS was found in patients receiving a trastuzumab-containing regimen (11.9 months). Triplet chemotherapy showed equal survival rates compared to doublets (OS: HR 0.92, 95%CI 0.83-1.02; TTF: HR 0.92, 95%CI 0.82-1.04) but significantly more grade 3-5 toxicity than doublets (33% vs. 21%, respectively). In conclusion, heterogeneity of first-line palliative systemic treatment in metastatic esophagogastric cancer patients is striking. Based on our data, doublet chemotherapy is the preferred treatment strategy because of similar survival and less toxicity compared to triplets.	esophagus
Clinical and Molecular Predictors of Response to Immune Checkpoint Inhibitors in Patients with Advanced Esophagogastric Cancer.	PURPOSE: Immune checkpoint inhibitors (ICI) are effective in only a minority of patients with esophagogastric cancer (EGC). Here, we aimed to identify predictors of durable clinical benefit to ICI in EGC. EXPERIMENTAL DESIGN: Patients with advanced EGC treated with ICIs at Memorial Sloan Kettering Cancer Center (New York, NY) were identified. Clinicopathologic variables were assessed. In patients profiled by MSK-IMPACT-targeted sequencing, outcomes were correlated with tumor genomic features. RESULTS: One-hundred sixty-one patients were treated with ICIs (110 with anti-PD-1/PD-L1 antibodies and 51 with anti-CTLA-4 and PD-1/PD-L1 antibodies). The median progression-free survival (PFS) and overall survival (OS) were 1.7 and 4.9 months, respectively. Greater number of disease sites (≥3), liver metastases, treatment with ≥3 prior therapies and ECOG performance status ≥2 were associated with poorer PFS and OS. Patients treated with combination ICI and those with PD-L1-positive tumors had improved outcomes. There was no difference in outcomes between patients treated with antibiotics during or in the 2 months preceding ICI treatment versus those who were not. Occurrence of irAEs was associated with improved OS. In genomically profiled tumors (n = 89), survival was associated with increasing tumor mutation burden (TMB). However, in multivariable analyses and when microsatellite unstable (MSI) patients were excluded, a significant association was no longer observed. CONCLUSIONS: In patients with advanced EGC, heavily pretreated patients, those with high-volume disease and/or poor PS were less likely to benefit from ICI. irAEs were associated with improved OS. TMB correlated with improved survival, but this association was not observed when MSI-high patients were excluded.	esophagus
The association between statin use and survival of esophageal cancer patients: A systematic review and meta-analysis.	Whether statin use has any impact on survival of esophageal cancer patients remains controversial. Therefore, we conducted a meta-analysis focusing on current topic for the first time.We systematically searched the following databases for relevant studies comparing survival between statin users and non-users among esophageal cancer patients up to March 16, 2019: Pubmed, Embase, and Web of Science. We extracted data of hazard ratio (HR) with 95%confidence interval (CI) of all-cause and cancer-specific mortality for analysis. We used the STATA 12.0 software to perform this meta-analysis.We finally included a total of 4 cohort studies involving a total of 20,435 esophageal cancer patients (5319 statin users and 15116 non-users). Our meta-analysis found that statin use after diagnosis of esophageal cancer was significantly correlated to decreased all-cause (random effects: HR = 0.81, 95%CI: 0.75-0.89, P < .001; I = 68.1%) and cancer-specific mortality (fixed effects: HR = 0.84, 95%CI: 0.78-0.89, P < .001; I = 46.6%) in esophageal cancer patients. When stratified by pathological subtypes, the protective effect of statin use after diagnosis of esophageal cancer was observed in both esophageal adenocarcinoma patients and esophageal squamous cell carcinoma patients. Moreover, statin use before diagnosis of esophageal cancer was also confirmed to have favorable survival benefit for esophageal cancer patients.Statin use was significantly correlated to lower mortality risk of esophageal cancer patients regardless of the time when statins were taken and pathological subtypes of esophageal cancer. Statins may serve as promising adjunctive anticancer agents for treating esophageal cancer.	esophagus
Nuclear magnetic resonance-based metabolomics and metabolic pathway networks from patient-matched esophageal carcinoma, adjacent noncancerous tissues and urine.	BACKGROUND: Several studies have demonstrated a correlation between esophageal cancer (EC) and perturbed urinary metabolomic profiles, but none has described the correlation between urine metabolite profiles and those of the tumor and adjacent esophageal mucosa in the same patient. AIM: To investigate how urinary metabolic phenotypes were linked to the changes in the biochemical landscape of esophageal tumors. METHODS: Nuclear magnetic resonance-based metabolomics were applied to esophageal tumor tissues and adjacent normal mucosal tissues alongside patient-matched urine samples. RESULTS: Analysis revealed that specific metabolite changes overlapped across both metrics, including glucose, glutamate, citrate, glycine, creatinine and taurine, indicating that the networks for metabolic pathway perturbations in EC, potentially involved in but not limited to disruption of fatty acid metabolism, glucose and glycolytic metabolism, tricarboxylic acid cycle and glutaminolysis. Additionally, changes in most urinary biomarkers correlated with changes in biomarker candidates in EC tissues, implying enhanced energy production for rapid cell proliferation. CONCLUSION: Overall, these associations provide evidence for distinct metabolic signatures and pathway disturbances between the tumor tissues and urine of EC patients, and changes in urinary metabolic signature could reflect reprogramming of the aforementioned metabolic pathways in EC tissues. Further investigation is needed to validate these initial findings using larger samples and to establish the underlying mechanism of EC progression.	esophagus
International Variation in Surgical Practices in Units Performing Oesophagectomy for Oesophageal Cancer: A Unit Survey from the Oesophago-Gastric Anastomosis Audit (OGAA).	BACKGROUND: Anastomotic leaks are associated with significant risk of morbidity, mortality and treatment costs after oesophagectomy. The aim of this study was to evaluate international variation in unit-level clinical practice and resource availability for the prevention and management of anastomotic leak following oesophagectomy. METHOD: The Oesophago-Gastric Anastomosis Audit (OGAA) is an international research collaboration focussed on improving the care and outcomes of patients undergoing oesophagectomy. Any unit performing oesophagectomy worldwide can register to participate in OGAA studies. An online unit survey was developed and disseminated to lead surgeons at each unit registered to participate in OGAA. High-income country (HIC) and low/middle-income country (LMIC) were defined according to the World Bank whilst unit volume were defined as < 20 versus 20-59 versus ≥60 cases/year in the unit. RESULTS: Responses were received from 141 units, a 77% (141/182) response rate. Median annual oesophagectomy caseload was reported to be 26 (inter-quartile range 12-50). Only 48% (68/141) and 22% (31/141) of units had an Enhanced Recovery After Surgery (ERAS) program and ERAS nurse, respectively. HIC units had significantly higher rates of stapled anastomosis compared to LMIC units (66 vs 31%, p = 0.005). Routine post-operative contrast-swallow anastomotic assessment was performed in 52% (73/141) units. Stent placement and interventional radiology drainage for anastomotic leak management were more commonly available in HICs than LMICs (99 vs 59%, p < 0.001 and 99 vs 83%, p < 0.001). CONCLUSIONS: This international survey highlighted variation in surgical technique and management of anastomotic leak based on case volume and country income level. Further research is needed to understand the impact of this variation on patient outcomes.	esophagus
HERG1 promotes esophageal squamous cell carcinoma growth and metastasis through TXNDC5 by activating the PI3K/AKT pathway.	BACKGROUND: The human ether a-go-go-related gene 1 (HERG1) is involved in tumor progression; however, its role in esophageal squamous cell carcinoma (ESCC) is not well studied. This study investigated HERG1 function in ESCC progression and elucidated the underlying mechanisms. METHODS: The prognostic value of HERG1 was determined by immunohistochemistry in ESCC biopsies. Cell growth and proliferation were analyzed by colony formation and methyl thiazolyl tetrazolium assays. Cell migration and invasion were analyzed by wound healing and Boyden transwell assays. Epithelial-mesenchymal transition (EMT) was evaluated by immunoblotting and quantitative polymerase chain reaction (qPCR). A xenograft mouse model was used to validate the tumorigenic and metastatic roles of HERG1 in vivo. RESULTS: HERG1 expression was overall higher in ESCC tissues compared to adjacent non-tumor tissues. A retrospective analysis of 349 patients with ESCC (stages I-IV) confirmed increased HERG1 expression was associated with disease progression and higher mortality rate. The overall survival of the patients was significantly worse when their tumors displayed higher HERG1 expression. HERG1 knockdown reduced tumor growth and metastasis in athymic mice. HERG1 affected the proliferation, migration, and invasion of two ESCC cell lines (TE-1 and KYSE-30). Changes in HERG1 expression affected the expression of cell cycle- and EMT-related proteins; these effects were reversed by altering the expression of thioredoxin domain-containing protein 5 (TXNDC5), which is also associated with the clinicopathological characteristics of patients with ESCC and is relevant to HERG1 in pathological biopsies. Additionally, HERG1 expression altered phosphoinositide 3-kinase (PI3K) and AKT phosphorylation, thereby affecting TXNDC5 expression. CONCLUSIONS: HERG1 contributes to poor prognosis in patients with ESCC by promoting ESCC cell proliferation, migration, and invasion via TXNDC5 through the PI3K/AKT signaling pathway. Our findings provided novel insights into the pathology of ESCC and role of HERG1 in tumor progression, suggesting that targeting HERG1 has potential diagnostic and therapeutic value for ESCC treatment.	esophagus
Table in the corner: a qualitative study of life situation and perspectives of the everyday lives of oesophageal cancer patients in palliative care.	"BACKGROUND: Incurable oesophageal cancer patients are often affected by existential distress and deterioration of quality of life. Knowledge about the life situation of this patient group is important to provide relevant palliative care and support. The purpose of this study is to illuminate the ways in which incurable oesophageal cancer disrupts the patients' lives and how the patients experience and adapt to life with the disease. METHODS: Seventeen patients receiving palliative care for oesophageal cancer were interviewed 1-23 months after diagnosis. The epistemological approach was inspired by phenomenology and hermeneutics, and the method of data collection, analysis and interpretation consisted of individual qualitative interviews and meaning condensation, inspired by Kvale and Brinkmann. RESULTS: The study reveals how patients with incurable oesophageal cancer experience metaphorically to end up at a ""table in the corner"". The patients experience loss of dignity, identity and community. The study illuminated how illness and symptoms impact and control daily life and social relations, described under these subheadings: ""sense of isolation""; ""being in a zombie-like state""; ""one day at a time""; and ""at sea"". Patients feel alone with the threat to their lives and everyday existence; they feel isolated due to the inhibiting symptoms of their illness, anxiety, worry and daily losses and challenges. CONCLUSIONS: The patients' lives are turned upside down, and they experience loss of health, function and familiar, daily habits. The prominent issues for the patients are loneliness and lack of continuity. As far as their normal everyday lives, social networks and the health system are concerned, patients feel they have been banished to a ""table in the corner"". These patients have a particular need for healthcare professionals who are dedicated to identifying what can be done to support the patients in their everyday lives, preserve dignity and provide additional palliative care."	esophagus
Tumor Compactness based on CT to predict prognosis after multimodal treatment for esophageal squamous cell carcinoma.	We aimed to establish a risk model using computed tomography-based compactness to predict overall survival (OS) and progression-free survival (PFS) after multimodal treatment for esophageal squamous cell carcinoma (ESCC). We extracted pre-treatment computed tomography-based tumor data (volume, surface area, and compactness) for 512 cases of ESCC that were treated at 3 centers. A risk model based on compactness was trained using Cox regression analyses of data from 83 cases, and then the model was validated using two independent cohorts (98 patients and 283 patients). The largest cohort (283 patients) was then evaluated using the risk model to predict response to radiotherapy with or without chemotherapy. In the three datasets, the pre-treatment compactness risk model provided good accuracy for predicting OS (P = 0.012, P = 0.022, and P = 0.003) and PFS (P < 0.001, P = 0.003, and P = 0.005). Patients in the low-risk group did not experience a significant OS benefit from concurrent chemoradiotherapy (P = 0.099). Furthermore, after preoperative concurrent chemoradiotherapy, the OS outcomes were similar among patients in the low-risk group who did and did not achieve a pathological complete response (P = 0.127). Tumor compactness was correlated with clinical T stage but was more accurate for predicting prognosis after treatment for ESCC, based on higher C-index values in all three datasets. The compactness-based risk model was effective for predicting OS and PFS after multimodal treatment for ESCC. Therefore, it may be useful for guiding personalized treatment.	esophagus
Capsaicin inhibits the migration and invasion via the AMPK/NF-κB signaling pathway in esophagus sequamous cell carcinoma by decreasing matrix metalloproteinase-9 expression.	Antitumor activity of Capsaicin has been studied in various tumor types, but its potency in esophageal squamous cell carcinoma (ESCC) remains to be elucidated. Here, we explored the molecular mechanism of the capsaicin-induced antitumor effects on ESCC Eca109 cells. Eca109 cells were treated with capsaicin in vitro, the migration and invasion capacities were significantly decreased by scratch assay and transwell invasion assay. Meanwhile, matrix metalloproteinase (MMP)-9 (MMP-9) expression levels were also obviously down-regulated by Western blot. However, phosphorylated AMPK levels were significantly up-regulated, and this effect was eliminated by the AMPK inhibitor Compound C treatment. In addition, capsaicin can enhance sirtuin1 (SIRT1) expression, which could activate nuclear factor-κB (NF-κB) through deacetylation, and activate AMPK inducing the phosphorylation of IκBα and nuclear localization of NF-κB p65. Overall, these results revealed that Capsaicin can inhibit the migration and invasion of ESCC cells via the AMPK/NF-κB signaling pathway.	esophagus
IL-6 and IL-8 secreted by tumour cells impair the function of NK cells via the STAT3 pathway in oesophageal squamous cell carcinoma.	BACKGROUND: Recurrence and metastasis are the leading causes of tumour-related death in patients with oesophageal squamous cell carcinoma (ESCC). Tumour-infiltrating natural killer cells (NK cells) display powerful cytotoxicity to tumour cells and play a pivotal role in tumour therapy. However, the phenotype and functional regulation of NK cells in oesophageal squamous cell carcinoma (ESCC) remains largely unknown. METHODS: Single cell suspensions from blood and tissue samples were isolated by physical dissociation and filtering through a 70 μm cell strainer. Flow cytometry was applied to profile the activity and function of NK cells, and an antibody chip experiment was used to identify and quantitate cytokine levels. We studied IL-6 and IL-8 function in primary oesophageal squamous carcinoma and NK cell co-cultures in vitro and by a xenograft tumour model in vivo. Western blotting was used to quantitate STAT3 (signal transducer and activator of transcription 3) and p-STAT3 levels. Finally, we performed an IHC array to analyse IL-6/IL-8 (interleukin 6/interleukin 8) expression in 103 pairs of tumours and matched adjacent tissues of patients with ESCC to elucidate the correlation between IL-6 or IL-8 and clinical characteristics. RESULTS: The percentages of NK cells in both peripheral blood and tumour tissues from patients with ESCC were significantly increased in comparison with those in the controls and correlated with the clinical characteristics. Furthermore, the decrease in activating receptors and increase in inhibitory receptors on the surface of tumour-infiltrating NK cells was confirmed by flow cytometry. The level of granzyme B, the effector molecule of tumour-infiltrating NK cells, was also decreased. Mechanistically, primary ESCC cells activated the STAT3 signalling pathway on NK cells through IL-6 and IL-8 secretion, leading to the downregulation of activating receptors (NKp30 and NKG2D) on the surface of NK cells. An ex vivo study showed that blockade of STAT3 attenuated the IL-6/IL-8-mediated impairment of NK cell function. Moreover, the expression of IL-6 or IL-8 in tumour tissues was validated by immunohistochemistry to be positively correlated with tumour progression and poor survival, respectively. CONCLUSIONS: Tumour cell-secreted IL-6 and IL-8 impair the activity and function of NK cells via STAT3 signalling and contribute to oesophageal squamous cell carcinoma malignancy.	esophagus
