Surveillance Implications of Recurrence Patterns in Early Node-Negative Esophageal Adenocarcinoma.	BACKGROUND: There are limited data regarding optimal surveillance after curative resection for esophageal cancer. Once disease recurrence is diagnosed, the prognosis is poor. The purpose of this article was to characterize disease recurrence in patients with early esophageal adenocarcinoma. METHODS: Two hundred sixty patients were identified from a prospective institutional database with pathologic T1 and T2 node-negative disease therapy treated with curative esophagectomy alone for esophageal adenocarcinoma between 1995 and 2017. Competing risk analysis was used to analyze factors associated with recurrence. RESULTS: The 5-year cumulative incidence of recurrence was 12%. Predictive factors for increased risk of recurrence included increasing tumor size, poor differentiation, and pathologic T2 disease (P < .05), whereas presence of Barrett's esophagus on pathology was protective. Recurrence within 2 years was 2.5%, 6.1%, and 12% for T1a, T1b, and T2 disease, respectively. At 5 years cumulative incidence of recurrence was 8.2%, 11.5% and 22.2%, respectively. Median overall survival after recurrence was 1.04 years (95% confidence interval, 0.7-2.4). There were 14 subclinical and 13 symptomatic recurrences; patients with symptomatic recurrence had a significantly shorter overall survival after recurrence occurred (0.31 vs 0.71 years, P = .018). CONCLUSIONS: Among early node-negative patients with esophageal cancer undergoing curative resection, 5-year recurrence was 12%. Survival after recurrence was poor, and only a few patients had isolated locoregional recurrence at time of diagnosis, suggesting that scheduled surveillance may have an important role.	esophagus
Squamous Cell Carcinoma in Lichen Planus of the Esophagus.	Cancer arising in lichen planus of the esophagus (LPE) is extremely rare. We report 2 elderly female patients with LPE who developed squamous cell carcinoma. Both underwent laparoscopic ischemic gastric preconditioning followed 2 weeks later by 3-field esophagectomy. Final pathological stages were carcinoma in situ and pT3N2, respectively. No adjuvant therapy was given. The patient with in situ cancer has no evidence of recurrence at 24 months. The second patient opted to follow up locally and died 8 months later. LPE should be closely monitored for malignant degeneration. Esophagectomy should be considered when malignancy is detected.	esophagus
LRRC8A Expression Influences Growth of Esophageal Squamous Cell Carcinoma.	The volume-regulated anion channel is composed of leucine-rich repeat-containing protein A (LRRC8A) and is activated by hypotonic conditions to implement the process of regulatory volume decrease. The role of LRRC8A in regulating genes related to progression of esophageal squamous cell carcinoma (ESCC) was investigated, as well as the prognostic significance of LRRC8A expression in this tumor. Knockdown experiments were conducted using ESCC cell lines and LRRC8A siRNA to assess the influence of this protein on tumor function. In addition, the gene expression profile of ESCC was determined by microarray analysis. Immunohistochemistry was performed on 64 primary tumor samples from ESCC patients receiving radical esophagectomy. It was found that depletion of LRRC8A decreased cell proliferation and migration and also promoted apoptosis. Microarray data demonstrated G(1)/S checkpoint regulation and up-regulation or down-regulation of phosphatidylinositol 3-kinase/AKT signaling, matrix metalloproteinase, and integrin signaling-related genes (including p21, p27, MMP1, and ITGAV) in LRRC8A-depleted cells. Immunohistochemistry showed that LRRC8A expression was related to the pathologic N and T stage categories, and strong LRRC8A expression was correlated with a worse prognosis of ESCC. These findings indicate that LRRC8A modulates tumor progression by influencing cell cycle, apoptosis, and migration, providing new insights into its function as an effector or biomarker of ESCC.	esophagus
Dracorhodin perchlorate induces apoptosis and G2/M cell cycle arrest in human esophageal squamous cell carcinoma through inhibition of the JAK2/STAT3 and AKT/FOXO3a pathways.	Dracorhodin perchlorate (DP), a synthetic analogue of the anthocyanin red pigment dracorhodin, has been shown to exert various pharmacological effects, including anticancer activity. However, its effects on human esophageal squamous cell carcinoma (ESCC) cells have not been previously investigated, and the molecular mechanisms underlying its anticancer activity remain unclear. In the present study, it was demonstrated that DP significantly reduced the viability of ESCC cells compared with that noted in normal human liver LO2 cells. Treatment with DP induced G2/M phase cell cycle arrest through upregulation of p21 and p27, and downregulation of cyclin B1 and Cdc2. Furthermore, DP treatment induced caspase‑dependent apoptosis, which could be reversed by exposure to Z‑VAD‑FMK, a caspase inhibitor. Western blotting demonstrated that DP induced apoptosis through extrinsic and intrinsic pathways by upregulating death receptor 4 (DR4), DR5, cleaved caspase‑3/‑7/‑9 and cleaved poly (ADP‑ribose) polymerase (PARP), and by decreasing total PARP, total caspase‑3/7, Bcl‑2 and caspase‑9/‑10. Moreover, DP treatment decreased the phosphorylation of Janus kinase 2 (JAK2), signal transducer and activator of transcription 3 (STAT3), AKT, and forkhead box O3a (FOXO3a) in ESCC cells, indicating that the activity of the JAK2/STAT3 and AKT/FOXO3a signaling pathways was inhibited. Therefore, DP is a promising therapeutic agent for ESCC.	esophagus
C-Phycocyanin elicited antitumor efficacy via cell-cycle arrest, apoptosis induction, and invasion inhibition in esophageal squamous cell carcinoma.	Objectives: Mounting evidence has demonstrated that C-Phycocyanin (C-PC) exhibits marked antitumor activity in a wide type of tumors, such as pancreas cancer, breast carcinoma, lung cancer, and colon cancer. The current study aimed to confirm the antitumor efficacy of C-PC in esophageal squamous cell carcinoma (ESCC). Methods: The efficacy of C-PC was evaluated against the proliferation of ESCC cell lines EC9706 and EC1 by CCK-8 kit and in a mice model of ESCC EC9706. Cell cycle and apoptosis were investigated by flow cytometry, and cell invasion was determined via transwell chamber. Protein expression was examined by Western blots. Results: We found that C-PC exhibited anti-proliferation ability in a time-dependent manner and a dose-dependent manner in ESCC EC9706 and EC1 cells. Besides, C-PC markedly arrested cell cycle in the G0/G1 phase, induced cell apoptosis and suppressed cell invasion ability in both EC9706 and EC1 cells (p < .01). Notably, C-PC evoked the elevations of Bax, PARP, and cleaved-caspase-3 protein, but reduced cyclin D1, CDK4, Bcl-2, MMP-2, and MMP-9 expression levels. Further investigation from in vivo experiment revealed that C-PC displayed significant antitumor efficacy in the xenografted EC9706 model. Conclusions: Our data presented herein suggest C-PC exerts antitumor efficacy in ESCC.	esophagus
Circulating human papillomavirus DNA detection in Barrett's dysplasia and esophageal adenocarcinoma.	There is evidence to suggest that human papillomaviruses (HPV) are associated with Barrett's dysplasia and esophageal adenocarcinoma. In other HPV-linked cancers such as cervical and oropharyngeal cancer, circulating HPV DNA is a potential biomarker to assist in tumor diagnosis and management. This study aimed to determine whether circulating HPV DNA was detectable in patients with Barrett's dysplasia and esophageal adenocarcinoma, and if so, whether there is any correlation with esophageal tissue HPV status. Plasma from 138 patients representing esophageal adenocarcinoma (N = 41), Barrett's dysplasia (N = 48) and hospital controls (N = 49) were analyzed for the presence of circulating HPV DNA using droplet-digital PCR targeting the E7 gene of HPV types 16 and 18. Circulating HPV DNA was detected in 11/138 (8.0%) study subjects including 1/49 (2.0%) hospital controls, 4/48 (8.3%) Barrett's dysplasia patients, and 6/41 (14.6%) esophageal adenocarcinoma patients. Detection of circulating HPV DNA was higher in patients with HPV-positive esophageal tissue (6/35, 17.1%) compared to those with HPV-negative specimens (5/103; 4.9%) (OR = 4.06; 95% CI 1.15-14.25; P = 0.020). The highest rates of detection occurred in esophageal adenocarcinoma patients, particularly those with invasive tumors that had breached the esophageal submucosa, had regional lymph node involvement or metastatic disease. Circulating HPV DNA was detectable in a subset of Barrett's dysplasia and esophageal adenocarcinoma patients. Detection was associated with tissue HPV positivity and possibly disease severity.	esophagus
Cardiac Toxicity in Operable Esophageal Cancer Patients Treated With or Without Chemoradiation.	PURPOSE: The purpose of this study was to evaluate predictors of cardiac events in esophageal cancer patients treated with neoadjuvant chemoradiotherapy (NA CRT) followed by surgery compared with surgery alone. MATERIALS AND METHODS: We retrospectively identified patients treated for esophageal cancer between 2006 and 2016. A total of 123 patients were identified; 70 were treated with surgery alone, and 53 were treated with NA CRT. Cardiac events were scored based on Common Terminology Criteria for Adverse Events (version 4.03), and dosimetric data was compiled for all patients who received radiation. Univariate analysis and multivariable analysis (MVA) were performed to identify predictors of cardiac events. Competing risk of death regression was performed to a model the cumulative incidence of cardiac events. RESULTS: The overall rates of grade ≥3 cardiac events were 24.5% in the NA CRT group versus 10% in the surgery group (P=0.04). On MVA, use of NA CRT (P<0.01, hazard ratio [HR]: 3.45, 95% confidence interval [CI]: 1.35-9.09) predicted for grade ≥3 cardiac events, though no dosimetric variable predicted for grade ≥3 cardiac events or overall survival. On MVA, NA CRT predicted for pericardial effusions of any grade (P<0.01, HR: 3.70, 95% CI: 1.67-8.33). The V45 Gy was the most significant predictor of pericardial effusions (P=0.012, HR: 1.03, 95% CI: 1.01-1.06) CONCLUSIONS:: NA CRT significantly increased the rate of grade ≥3 cardiac events compared with patients treated with surgery alone. Although no dosimetric parameter predicted for grade ≥3 cardiac events or survival, the V45 Gy predicted for pericardial effusions.	esophagus

Association of skeletal muscle loss with the long-term outcomes of esophageal cancer patients treated with neoadjuvant chemotherapy.	PURPOSE: To investigate the change in skeletal muscle mass and evaluate the prognostic impact of sarcopenia on esophageal cancer (EC) patients METHODS: The subjects of this retrospective study were 90 EC patients who were treated with neoadjuvant chemotherapy (NAC) and subsequent esophagectomy. The skeletal muscle index (SMI) was defined according to computed tomography (CT) imaging of the total cross-sectional muscle tissue, measured at the third lumbar level using a volume analyzer before NAC and surgery. The SMI was calculated by normalization according to height, and skeletal muscle loss (SML) was defined as (pre-NAC SMI value - preoperative SMI value) × 100/pre-NAC SMI. RESULTS: Sarcopenia was evident in 72 (80.0%) patients before NAC and 77 (85.6%) patients before NAC and surgery. The SMI value was decreased in 28 (68.9%) patients and the median SML was 3.3%. The 3-year overall survival rate was 68.9% in the low SML group and 0% in the high SML group (P < 0.001). Sarcopenia before NAC or surgery was not significantly associated with overall survival. Multivariable analysis identified high SML as an independent prognostic factor. CONCLUSIONS: These results suggest that skeletal muscle loss is associated with a worse long-term outcome for EC patients treated with NAC.	esophagus
Ultrasonographic imaging of calcifying fibrous tumor of cervical esophagus: A case report.	RATIONALE: Calcifying fibrous tumor (CFT) is a rare benign mesenchymal tumor characterized by cytologically benign fibroblasts that produce abundant collagen with scattered lymphocytes, plasma cells, and psammomatous or dystrophic calcifications. PATIENT CONCERNS: A 37 years old women was initially diagnosed thyroid nodule in local hospital. She was referred to receive microwave ablation of the nodule in our hospital. The patient was in good health with occasional foreign body sensation in the neck. Routine laboratory examination was normal. DIAGNOSIS: The lesion was suspected benign and originating from the esophagus rather than the thyroid gland by conventional ultrasound and contrast-enhanced ultrasound in our hospital and was finally proved to be CFT by pathology. INTERVENTIONS: The lesion was surgically removed. OUTCOMES: The patient recovered well and was followed up for 2 years without recurrence. LESSONS: Although imaging diagnosis of CFT is difficult, the findings of clear border, coarse calcification on conventional ultrasound and peripheral hypoenhancement without central enhancement on contrast-enhanced ultrasound (CEUS), together with real-time evaluation of the relationship between the tumor and esophagus help to distinguish CFT of cervical esophagus from other lesions in the neck.	esophagus
Increased risk of esophageal squamous cell carcinoma associated with frequent and long-term consumption of salted meat and salted fat.	OBJECTIVE: This study aimed to investigate the association between the consumption of salted meat and salted fat and esophageal cancer risk among individuals with normal esophageal mucosa or esophagitis. METHODS: This case-control study enrolled 216 individuals from Yanting County. Information on the consumption of salted meat and salted fat was collected using a food-frequency questionnaire validated among Yanting people. RESULTS: Higher intake frequencies (≥once a week) of salted meat and salted fat were associated with 2.40-fold and 7.37-fold increased risks of esophageal cancer among individuals with normal esophageal mucosa, while long-term intakes (≥6 months) increased the risks by 6.87-fold and 85.45-fold, respectively. Similarly, the odds ratios (ORs) of patients with esophagitis developing esophageal cancer from frequent intakes of salted meat and salted fat were 6.48 and 5.05, respectively, and the ORs associated with long-term intakes were 44.38 and 74.90, respectively. CONCLUSIONS: Frequent and long-term consumption of salted meat and salted fat could increase the risk of esophageal cancer in individuals from Yanting with normal esophageal mucosa or esophagitis. Efforts should thus be made to reduce the consumption of these foods among people in this region.	esophagus
Quality Assurance of Dose-Escalated Radiation Therapy in a Randomized Trial for Locally Advanced Oesophageal cancer.	PURPOSE: The ongoing phase 2/3 PRODIGE 26/CONCORDE trial compares chemoradiation therapy with and without dose escalation in patients with locally advanced or unresectable esophageal cancer. The results of a benchmark case procedure are reported here to evaluate the protocol compliance of participating centers as part of quality assurance for radiation therapy. METHODS AND MATERIALS: Volume delineation, target coverage, and dose constraints to the organs at risk (OARs) were assessed on treatment plans of a common benchmark case performed by each participating center. The centers were classified in 3 categories: per protocol, minor acceptable deviation (MiD), or major unacceptable deviation (MaD). A plan was rejected if ≥4 MiDs or 1 MaD were found. RESULTS: Thirty-5 centers submitted 43 plans. Among them, 14 (32.6%) were per protocol, 19 (44.2%) presented at least 1 MiD, 2 (4.6%) presented at least 1 MaD, and 8 (18.6%) presented both MiD and MaD. Overall, 11 (25.6%) plans were rejected. Only 1 plan was rejected because gross tumor volume was not correctly delineated. The OAR delineation was respected in all cases. Dose constraints to the OARs were respected in the majority of cases except for the heart, where one-third of the plans presented a deviation. As for the target volume, 3 plans (5.8%) had a major underdosage and 1 plan (1.9%) had a major overdosage. Overall, 58% of all treatments were planned with intensity modulated radiation therapy, whereas 42% were planned with 3-dimensional chemoradiation therapy. Significantly more plans in the intensity modulated radiation therapy group were accepted compared with the 3-dimensional chemoradiation therapy group (P = .03). CONCLUSION: The high frequency of protocol deviations underlines the importance of a quality assurance program in clinical trials. Further work should assess the impact of quality assurance for radiation therapy on patient outcomes.	esophagus
MiR-296-5p inhibits cell invasion and migration of esophageal squamous cell carcinoma by downregulating STAT3 signaling.	OBJECTIVE: Many studies have emphasized the function of microRNA-296 (miR-296) that inhibits tumor formation. To some extent, the role of miR-296 in esophageal squamous cell carcinoma (ESCC) remains misleading. Therefore, the current research was designed to investigate the regulatory mechanisms of miR-296 and signal transducer and activator of transcription 3 (STAT3) in ESCC. PATIENTS AND METHODS: The mRNA expression of miR-296-5p and STAT3 in ESCC tissues or cell lines was measured via quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The protein level of STAT3 was measured by Western blotting assay. The Luciferase reporter assay was used to verify the binding sites between miR-296-5p and STAT3. The transwell assay was employed to identify cell migration and invasion. RESULTS: Down-regulation of miR-296-5p was detected in ESCC tissues and cell lines (p<0.01). Additionally, miR-296-5p was found to target STAT3 directly. Functionally, up-regulation of miR-296-5p or down-regulation of STAT3 significantly inhibited cell migration and invasion in ESCC. CONCLUSIONS: MiR-296-5p inhibited cell invasion and migration in ESCC by downregulating STAT3. The overexpression of miR-296-5p by targeting STAT3 suppressed tumorigenesis of ESCC cells.	esophagus
The transcription factor LEF1 promotes tumorigenicity and activates the TGF-β signaling pathway in esophageal squamous cell carcinoma.	BACKGROUND: Esophageal squamous cell carcinoma (ESCC) is the most difficult subtype of esophageal cancer to treat due to the paucity of effective targeted therapy. ESCC is believed to arise from cancer stem cells (CSCs) that contribute to metastasis and chemoresistance. Despite advances in diagnosis and treatment, the prognosis of ESCC patients remains poor. METHODS: In this study, we applied western blot, quantitative real-time polymerase chain reaction (qRT-PCR), immunohistochemistry, RNA-Seq analysis, luciferase reporter assay, Chip-qPCR, bioinformatics analysis, and a series of functional assays to show the potential role of LEF1 in regulating esophageal CSCs. RESULTS: We found that the overexpression of LEF1 was associated with aberrant clinicopathological characteristics and the poor prognosis of ESCC patients. In addition, the elevated expression of LEF1 and OV6 was significantly associated with aberrant clinicopathological features, and poor patient prognosis. Moreover, the overexpression of LEF1 was observed in esophageal CSCs purified by the magnetic sorting of adherent and spheroidal ESCC cells. The increased level of LEF1 in CSCs facilitated the expression of CSC markers, stem cell-like properties, resistance to chemotherapy, and tumorigenicity and increased the percentage of CSCs in ESCC samples. Conversely, the knockdown of LEF1 significantly diminished the self-renewal properties of ESCC. We showed that LEF1 played an important mechanical role in activating the TGF-β signaling pathway by directly binding to the ID1 gene promoter. A positive association between LEF1 and ID1 expression was also observed in clinical ESCC samples. CONCLUSION: Our results indicate that the overexpression of LEF1 promotes a CSC-like phenotype in and the tumorigenicity of ESCC by activating the TGF-β signaling pathway. The inhibition of LEF1 might therefore be a novel therapeutic target to inactivate CSCs and inhibit tumor progression.	esophagus
Clinical characteristics of young patients with early Barrett's neoplasia.	BACKGROUND: Esophageal adenocarcinoma (EAC) and high-grade dysplasia (HGD) may appear in young patients with Barrett's esophagus (BE). However, characteristics of Barrett's-related neoplasia in this younger population remain unknown. AIM: To identify clinical characteristics that differ between young and old patients with early-stage Barrett's-related neoplasia. METHODS: We conducted a retrospective analysis of a prospectively maintained database comprised of consecutive patients with early-stage EAC (pT1) and HGD at a tertiary-referral center between 2001 and 2017. Baseline characteristics, drug and risk factor exposures, clinicopathological staging of EAC/HGD and treatment outcomes [complete eradication of neoplasia (CE-N), complete eradication of intestinal metaplasia (CE-IM), recurrence of neoplasia and recurrence of intestinal metaplasia] were retrieved. Multivariate analyses were performed to identify factors that differed significantly between older and younger (≤ 50 years) patients. RESULTS: We identified 450 patients with T1 EAC and HGD (74% and 26%, respectively); 45 (10%) were ≤ 50 years. Compared to the older group, young patients were more likely to present with ongoing gastroesophageal reflux disease (GERD) symptoms (55% vs 38%, P = 0.04) and to be obese (body mass index > 30, 48% vs 32%, P = 0.04). Multivariate logistic regression analysis showed that young patients were significantly more likely to have ongoing GERD symptoms [odds ratio (OR) 2.00, 95% confidence interval (CI) 1.04-3.85, P = 0.04] and to be obese (OR 2.06, 95%CI 1.07-3.98, P = 0.03) whereas the young group was less likely to have a smoking history (OR 0.39, 95%CI 0.20-0.75, P < 0.01) compared to the old group. However, there were no significant differences regarding tumor histology, CE-N, CE-IM, recurrence of neoplasia and recurrence of intestinal metaplasia (mean follow-up, 44.3 mo). CONCLUSION: While guidelines recommend BE screening in patients > 50 years of age, younger patients should be considered for screening endoscopy if they suffer from obesity and GERD symptoms.	esophagus
