Acute Kidney Injury After Esophageal Cancer Surgery: Incidence, Risk Factors, and Impact on Oncologic Outcomes.	OBJECTIVE: To determine the incidence, risk factors, and consequences of AKI in patients undergoing surgery for esophageal cancer. SUMMARY OF BACKGROUND DATA: Esophageal cancer surgery is an exemplar of major operative trauma, with well-defined risks of respiratory, cardiac, anastomotic, and septic complications. However, there is a paucity of literature regarding AKI. METHODS: consecutive patients undergoing curative-intent surgery for esophageal cancer from 2011 to 2017 in 3 high-volume centers were studied. AKI was defined according to the AKI Network criteria. AKI occurred if, within 48 hours postoperatively, serum creatinine rose by 50% or by 0.3 mg/dL (26.5 μmol/L) from preoperative baseline. Complications were recorded prospectively. Multivariable logistic regression determined factors independently predictive of AKI. RESULTS: A total of 1135 patients (24.7%:75.3% female:male, with a mean age of 64, a baseline BMI of 27 kg m-2, and dyslipidemia in 10.2%), underwent esophageal cancer surgery, 85% having an open thoracotomy. Overall in-hospital mortality was 2.1%. Postoperative AKI was observed in 208 (18.3%) patients, with AKI Network 1, 2, and 3 in 173 (15.2%), 28 (2.5%), and 7 (0.6%), respectively. Of these, 70.3% experienced improved renal function within 48 hours. Preoperative factors independently predictive of AKI were age [P = 0.027, odds ratio (OR) 1.02 (1.00-1.04)], male sex [P = 0.015, OR 1.77 (1.10-2.81)], BMI at diagnosis [P < 0.001, OR 1.10 (1.07-1.14)], and dyslipidemia [P = 0.002, OR 2.14 (1.34-3.44)]. Postoperatively, AKI was associated with atrial fibrillation (P = 0.013) and pneumonia (P = 0.005). Postoperative AKI did not impact survival outcomes. CONCLUSION: AKI is common but mostly self-limiting after esophageal cancer surgery. It is associated with age, male sex, increased BMI, dyslipidemia, and postoperative morbidity.	esophagus
GRB7 is an oncogenic driver and potential therapeutic target in oesophageal adenocarcinoma.	Efficacious therapeutic approaches are urgently needed to improve outcomes in patients with oesophageal adenocarcinoma (OAC). However, oncogenic drivers amenable to targeted therapy are limited and their functional characterisation is essential. Among few targeted therapies available, anti-human epidermal growth factor receptor 2 (HER2) therapy showed only modest benefit for patients with OAC. Herein, we investigated the potential oncogenic role of growth factor receptor bound protein 7 (GRB7), which is reported to be co-amplified with HER2 (ERBB2) in OAC. GRB7 was highly expressed in 15% of OAC tumours, not all of which could be explained by co-amplification with HER2, and was associated with a trend for poorer overall survival. Knockdown of GRB7 decreased proliferation and clonogenic survival, and induced apoptosis. Reverse phase protein array (RPPA) analyses revealed a role for PI3K, mammalian target of rapamycin (mTOR), MAPK, and receptor tyrosine kinase signalling in the oncogenic action of GRB7. Furthermore, the GRB7 and HER2 high-expressing OAC cell line Eso26 showed reduced cell proliferation upon GRB7 knockdown but was insensitive to HER2 inhibition by trastuzumab. Consistent with this, GRB7 knockdown in vivo with an inducible shRNA significantly inhibited tumour growth in cell line xenografts. HER2 expression did not predict sensitivity to trastuzumab, with Eso26 xenografts remaining refractory to trastuzumab treatment. Taken together, our study provides strong evidence for an oncogenic role for GRB7 in OAC and suggests that targeting GRB7 may be a potential therapeutic strategy for this cancer. © 2020 The Authors.

Validation Study of Fibrinogen and Albumin Score in Esophageal Cancer Patients Who Underwent Esophagectomy: Multicenter Prospective Cohort Study.	PURPOSE: To arrange multidisciplinary treatment for esophageal cancer, a simple and accurate predictive marker for prognosis is required. The current multicenter prospective study aims to validate the prognostic significance of fibrinogen and albumin score (FA score) for esophageal cancer patients. PATIENTS AND METHODS: Patients who were planned to undergo surgical resection for esophageal cancer at four participating institutions were enrolled in this study. Patient background, clinicopathological factors, and blood concentration of plasma fibrinogen and albumin were collected. Patients with elevated fibrinogen and decreased albumin levels were allocated a score of 2; those with only one of these abnormalities were allocated a score of 1; and those with neither of these abnormalities were allocated a score of 0. Recurrence-free survival (RFS) and overall survival (OS) were evaluated as a primary endpoint. RESULTS: From four participating institutions, 133 patients were registered for the current analysis. The distribution of FA score of 0/1/2 was 84 (63%)/34 (26%)/15 (11%), respectively. In the analysis of primary endpoint, the preoperative FA score significantly classified RFS (FA score 1/2: HR 2.546, p = 0.013/6.989, p < 0.001) and OS (FA score 1/2: HR 2.756, p = 0.010/6.970, p < 0.001). We further evaluated the prognostic significance of FA score under stratification by pStage. As a result, with increasing FA score, RFS and OS were significantly worse in both pStage 0-I and II-IV groups. CONCLUSIONS: The prognostic impact of preoperative FA score was confirmed for esophageal cancer patients in the current multicenter prospective trial. FA score can be considered to predict postoperative survival and rearrange the treatment strategy before esophagectomy.	esophagus
Prognostic Significance of Complete Pathologic Response Obtained with Chemotherapy Versus Chemoradiotherapy in Gastric Cancer.	BACKGROUND: Few studies have compared the survival advantage of complete pathologic response (cPR) achieved through neoadjuvant chemotherapy (nCT) versus neoadjuvant chemoradiotherapy (nCRT) in gastric adenocarcinoma. Our study utilizes a large national cancer database to address this question. PATIENTS AND METHODS: This is a retrospective review of patients with clinical stage I to III gastric adenocarcinoma from 2004 to 2013 who received nCT or nCRT. Patients who achieved cPR were selected. Associations were evaluated using Mann-Whitney U and Fisher's exact tests. Survival information was summarized using standard Kaplan-Meier methods, where estimates of the median and 5-year survival rates were estimated with 95% confidence intervals. RESULTS: A total of 413 patients who had cPR were identified. Eighty-four patients received nCT and 329 patients received nCRT. Patients in the nCRT group had higher clinical stage (88.4% vs. 75.0%) and more proximal location of tumors (95.4% vs. 45.2%). The nCT group (n = 84) had a 94% 5-year survival rate, while the nCRT group's (n = 329) rate was 60% (p < 0.001). On Cox regression modeling using a propensity-weighted approach, nCT treatment was an independent predictor of improved overall survival (nCRT vs. nCT; HR 10.44, p < 0.001). CONCLUSIONS: The use of nCT leads to a significant increase in overall survival in patients when compared with nCRT for those who achieved cPR in gastric adenocarcinoma. While this study is limited in identifying the cause for this difference in overall survival, this important finding nonetheless requires further investigation and should be considered in the development of future gastric cancer trials.	esophagus
The effect of prophylactic thoracic duct ligation during esophagectomy on the incidence of chylothorax and survival of the patients: an updated review.	BACKGROUND: The role of thoracic duct ligation (TDL) during esophagectomy remains controversial. This review aimed to elucidate the effect of TDL on chylothorax and survival of the patients after esophagectomy for cancer. METHODS: We searched articles from PubMed, Web of Science, Scopus, Cochrane, and Google Scholar till May 2020 according to the PRISMA guidelines using the terms of [Oesophagectomy OR esophagectomy] AND [chylothorax] AND [thoracic duct ligation]. Only those compared the incidence of chylothorax in patients who ligated or resected the thoracic duct (ligation group) or preserved the thoracic duct (preservation group) were selected. RESULTS: First, 15 studies including one randomized controlled trial were collected for meta-analysis regarding post-esophagectomy chylothorax. Of these, 3658 patients underwent TDL and 4638 cases preserved the thoracic duct. Both groups showed similar chylothorax rate (odd ratios 0.73 in favor of ligation group; 95% conﬁdence interval [CI] 0.50-1.07, p = 0.11). Second, four studies providing survival information were included for another meta-analysis, and the patients in preservation group demonstrated better 5-year overall survival compared to those in ligation group (odds ratio 1.25; 95% CI 1.08-1.44, p = 0.002). CONCLUSIONS: The present review provided updated evidence opposing prophylactic TDL during esophagectomy for lowering chylothorax. Considering the harmful effect of TDL on survival of the patients, further well-designed trials should be considered in selected cases under strict supervision.	esophagus
Assessment of PPARGC1A, PPARGC1B, and PON1 Genetic Polymorphisms in Esophageal Squamous Cell Carcinoma Susceptibility in the Eastern Chinese Han Population: A Case-Control Study Involving 2351 Subjects.	Previous studies suggested that alterations in the energy metabolism might be underlying cancer initiation and progression. Polymorphisms of genes involved in energy metabolism regulation, such as peroxisome proliferator-activated receptor gamma coactivator 1α (PPARGC1A), -β (PPARGC1B), and paraoxonase 1 (PON1), might confer susceptibility to esophageal squamous cell carcinoma (ESCC) and partially explain its pathogenesis. We investigated the effects of several single nucleotide polymorphisms (SNPs) in three metabolic-related genes (e.g., PPARGC1A, PPARGC1B, and PON1) on ESCC susceptibility. In total, 829 patients with sporadic ESCC and 1522 nontumor controls were enrolled in the study. SNPs were genotyped using PCR-ligase detection reaction. Our study revealed that the PPARGC1A rs3736265 G/A SNP significantly increased the risk for ESCC (GA vs. GG: adjusted odds ratio [OR] = 1.25, 95% confidence interval [95% CI] = 1.02-1.54, p = 0.034; GA+AA vs. GG: adjusted OR = 1.25, 95% CI = 1.03-1.52, p = 0.027]. In addition, a stratified analysis revealed that the PPARGC1A rs3736265 SNP was correlated with the development of ESCC in male and nondrinking subgroups. We also confirmed that the PPARGC1B rs17572019 G/A SNP promoted the risk of ESCC in subgroup with high alcohol intake. The PPARGC1A rs8192678 C/T polymorphism decreased the susceptibility of ESCC in men. These findings highlight that polymorphisms in PPARGC1A and PPARGC1B may contribute to ESCC susceptibility. In the future, further well-designed epidemiological studies are needed to confirm our findings.	esophagus
Identification of the distinct genomic features in gastroesophageal junction adenocarcinoma and its Siewert subtypes.	Rates of gastroesophageal junction adenocarcinomas (GEJAs) have shown an alarming increase; however, the genetic background of GEJA and its Siewert classification have yet to be uncovered. Here, 60 paired tumor and normal DNA samples from GEJA patients were analyzed by whole-exome sequencing. Among them, 13 were Siewert type I, 14 were type II, and 33 were type III. A predominance of C/G>T/A substitutions was discovered in GEJA, followed by C/G>A/T substitutions. Notably, Siewert type I and type II/III display distinct sets of driver genes, mutational spectrum, and recurrently disrupted pathways. Siewert type I showed similarity to esophageal adenocarcinomas (EACs) and the chromosomal instability subtype of stomach adenocarcinomas, while Siewert type II/III showed similarity to the genomic stable subtype of stomach adenocarcinoma. We also found that mutation of FBXW7, a driver gene of GEJA, was enriched in Siewert type I. Our data identify differences between GEJA and stomach/EACs at the genomic level and provide evidence for differential treatment based on Siewert classification of GEJA. © 2020 The Pathological Society of Great Britain and Ireland.

Identification of Differentially Expressed Genes and miRNAs Associated with Esophageal Squamous Cell Carcinoma by Integrated Analysis of Microarray Data.	To identify candidate key genes and miRNAs associated with esophageal squamous cell carcinoma (ESCC) development and prognosis, the gene expression profiles and miRNA microarray data including GSE20347, GSE38129, GSE23400, and GSE55856 were downloaded from the Gene Expression Omnibus (GEO) database. Clinical and survival data were retrieved from The Cancer Genome Atlas (TCGA). Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of differentially expressed genes (DEGs) was analyzed via DAVID, while the DEG-associated protein-protein interaction network (PPI) was constructed using the STRING database. Additionally, the miRNA target gene regulatory network and miRNA coregulatory network were constructed, using the Cytoscape software. Survival analysis and prognostic model construction were performed via the survival (version 2.42-6) and rbsurv R packages, respectively. The results showed a total of 2575, 2111, and 1205 DEGs, and 226 differentially expressed miRNAs (DEMs) were identified. Pathway enrichment analyses revealed that DEGs were mainly enriched in 36 pathways, such as the proteasome, p53, and beta-alanine metabolism pathways. Furthermore, 448 nodes and 1144 interactions were identified in the PPI network, with MYC having the highest random walk score. In addition, 7 DEMs in the microarray data, including miR-196a, miR-21, miR-205, miR-194, miR-103, miR-223, and miR-375, were found in the regulatory network. Moreover, several reported disease-related miRNAs, including miR-198a, miR-103, miR-223, miR-21, miR-194, and miR-375, were found to have common target genes with other DEMs. Survival analysis revealed that 85 DEMs were related to prognosis, among which hsa-miR-1248, hsa-miR-1291, hsa-miR-421, and hsa-miR-7-5p were used for a prognostic survival model. Taken together, this study revealed the important roles of DEGs and DEMs in ESCC development, as well as DEMs in the prognosis of ESCC. This will provide potential therapeutic targets and prognostic predictors for ESCC.	esophagus
TWIST1 correlates with Notch signaling pathway to develop esophageal squamous cell carcinoma.	Notch signaling pathway mediates different biological processes including stem cell self-renewal, progenitor cell fate decision, and terminal differentiation. TWIST1 plays a key role in tumor development and metastasis through inducing epithelial-mesenchymal transition (EMT). Expression of the core transcriptional complex of Notch pathway and its target genes, as well as TWIST1 overexpression, are closely related to the aggressive clinicopathological variables of esophageal squamous cell carcinoma (ESCC). Here we aimed to functionally elucidate probable crosstalk between TWIST1 and Notch pathway in ESCCs. Correlation between TWIST1 and Notch target genes was analyzed in 50 ESCCs and corresponding normal tissues. Using retroviral system, enforced expression of TWIST1 was established in ESCC line KYSE-30 cells and expression of Notch signaling genes was assessed. Significant correlation between TWIST1 and HEY1/HEY2 expression was found in different pathological variable of ESCC poor prognosis. Induced expression of TWIST1 in KYSE-30 cells caused a noteworthy increase of Notch pathway genes expression revealing regulatory role of TWIST1 on Notch signaling genes in the cells. Based on existed correlations between expression of TWIST1 and Notch pathway genes in different pathological features of ESCC patients, as well as KYSE-30 cell line, we may extrapolate that TWIST1 is involved in aggressiveness of the disease through regulation of Notch signaling genes. To the best of knowledge, this is the first report describing the impact of TWIST1 on Notch cascade genes in ESCC.	esophagus
Hydrogen-bubbled platinum-colloid suppresses human esophagus- or tongue-carcinoma cells with intracellular platinum-uptake and the diminished normal-cell mortality.	Carcinostatic effects of combined use of hydrogen nano-bubbles (nano-H) and platinum-povidone (PVP--Pt) were examined. Hydrogen-dissolved medium was prepared by hydrogen-gas bubbling with a microporous gas-emittance-terminal into a medium in the absence or presence of PVP-Pt (nano-H, nano-H/PVP-Pt). Human esophagus-derived carcinoma cells KYSE70 were repressed for cell proliferation with nano-H/PVP-Pt more markedly than with nano-H, indicating the hydrogen-intensification for PVP-Pt-alone-carcinostasis. However, the intensified carcinostasis required co-administration of nano-H and PVP-Pt, and no intensified carcinostasis was shown in two-step separate administration of nano-H and PVP-Pt. Furthermore, hydrogen bubbling into PVP-Pt-containing medium achieved more appreciable carcinostasis than mere addition of PVP-Pt into nano-H-containing medium, indicating the potent interaction of hydrogen and PVP-Pt. The nano-H/PVP-Pt-administered human tongue-derived carcinoma cells HSC-4 were repressed for cell proliferation more markedly than pre-malignant human tongue-derived epitheliocytes DOK, concurrently with more abundant intracellular Pt-intake into HSC-4 cells than DOK as analyzed by ICP-MS. Thus, PVP-Pt is able to adsorb hydrogen nano-bubbles on Pt and applicable for cancer therapy by diminishing the side-effects to normal cells.	esophagus
Ubiquitin-specific peptidase 46 promotes tumor metastasis through stabilizing ENO1 in human esophageal squamous cell carcinoma.	Esophageal squamous cell carcinoma (ESCC) has high aggressiveness and poor prognosis, and is the major histological subtype of esophageal cancer in East Asia and East Africa. In this study, we found that USP46, a deubiquitinating enzyme, is overexpressed in clinical ESCC samples, especially in patients with positive lymph node metastasis. Moreover, USP46 enhances the migration and invasion of ESCC cells by mediating the EMT process in vitro, and promotes lymph nodes and lung metastasis of ESCC in vivo. In addition, we found that USP46 is a bona fide deubiquitinating enzyme to stabilize the protein level of ENO1 through deubiquitination. ENO1 protein level was also positively correlated with USP46 in the ESCC samples. In summary, these findings reveal the functional role of USP46 as a deubiquitinating enzyme on ESCC metastasis, providing us a potential therapeutic target for the treatment of ESCC.	esophagus
Incidental Detection of Elastofibroma Dorsi With 68Ga-FAPI-46 and 18F-FDG PET/CT in a Patient With Esophageal Cancer.	A 71-year-old man underwent 18F-FDG and 68Ga-FAPI-46 PET/CT for initial staging prior to surgery of a squamous cell carcinoma of the lower esophagus under the prospective study NCT04147494. Both scans showed increased uptake in the mid and distal esophagus without evidence of metastatic disease. A soft tissue right infrascapular mass with mild 18F-FDG and moderate 68Ga-FAPI-46 uptake was incidentally found. The patient underwent robotic-assisted Ivor-Lewis esophagectomy and excision of the right infrascapular mass. Histopathology of the right chest wall mass confirmed the diagnosis of elastofibroma.	esophagus
Multi-faceted epigenetic dysregulation of gene expression promotes esophageal squamous cell carcinoma.	Epigenetic landscapes can shape physiologic and disease phenotypes. We used integrative, high resolution multi-omics methods to delineate the methylome landscape and characterize the oncogenic drivers of esophageal squamous cell carcinoma (ESCC). We found 98% of CpGs are hypomethylated across the ESCC genome. Hypo-methylated regions are enriched in areas with heterochromatin binding markers (H3K9me3, H3K27me3), while hyper-methylated regions are enriched in polycomb repressive complex (EZH2/SUZ12) recognizing regions. Altered methylation in promoters, enhancers, and gene bodies, as well as in polycomb repressive complex occupancy and CTCF binding sites are associated with cancer-specific gene dysregulation. Epigenetic-mediated activation of non-canonical WNT/β-catenin/MMP signaling and a YY1/lncRNA ESCCAL-1/ribosomal protein network are uncovered and validated as potential novel ESCC driver alterations. This study advances our understanding of how epigenetic landscapes shape cancer pathogenesis and provides a resource for biomarker and target discovery.	esophagus
Clinical characteristics and surgical treatment of esophageal cancer spinal metastasis - A single center 10-year retrospective study.	OBJECTIVE: Our research aims to discuss the clinical characteristics, treatment methods, and prognostic characteristics of patients with esophageal cancer spinal metastasis. It is one of the largest clinical studies on the disease to date. The purpose is to improve clinicians' understanding of the clinical features and prognosis of esophageal spine metastases and share our experience in dealing with this entity. METHODS: Six patients with spinal metastasis due to esophageal cancer who had received surgical treatment at the bone tumor center of Peking Union Medical College Hospital from January 2010 to January 2020 were selected. The clinical data, surgical records, imaging examinations, pathological reports, and immunohistochemical results of all patients were reviewed by the team. In the study, we applied two surgical treatments, namely open surgery and percutaneous vertebroplasty. Radiotherapy, chemotherapy, and targeted therapy were used as adjuvant treatments. Retrospective analysis of the patient's basic clinical data were analyzed. RESULTS: All six patients with metastatic spinal esophageal cancer (MSEC) were male with an average age of 58.0 ± 5.3 years. The average duration between the esophageal cancer resection and diagnosis of spinal metastases was 24.8 (2-72) months. Of the six patients, four had spinal metastases located in the thoracic spine and two had metastases located in the lumbar spine. We referred to the revised Tokuhashi score and Tomita score to recommend individualized surgical treatment plans for patients, and fully respected the patients' wishes. All six patients underwent surgical treatment, a total of six operations, including four percutaneous vertebroplasty and two open surgery. After the operations, the symptoms of the patients improved significantly. During the follow-up, all six patients died of the disease with the average time from spinal surgery to death being 8.8 ± 3.7 months. CONCLUSIONS: In general, patients with esophageal cancer spine metastases have a poor prognosis, and the average survival time of these patients often does not exceed 12 months. The combination of surgical treatment and postoperative adjuvant therapy can control symptoms effectively and improve the patient's quality of life.	esophagus
