Quality of the patient-oriented web-based information on esophageal cancer.	This study was aimed to analyze the readability and quality of patient education websites on esophageal cancer. Yahoo!, Google, and Bing search engines were searched using keywords esophageal cancer, esophageal tumor, esophageal tumor, esophageal malignancy, esophageal cancer, esophageal tumor, esophageal tumor, and esophageal malignancy. The first 50 websites resulting in each keyword search were evaluated using validated FRES, LIDA, and DISCERN scores to assess readability, usability, and reliability, and quality of information, respectively. Non-parametric tests were used for statistical analysis. A total of 108 eligible websites were included in the analysis. Thirty (27.8%) out of the 108 eligible web sites had obtained Health on the Net (HON) code certification. The median FRES score of the included websites was 48.25 out of 100 (range: 15.6-70.1). The median LIDA usability and reliability scores were 46.5 out of 54 (range: 22-54) and 39.0 out of 51 (range: 10-51), respectively. The median DISCERN score was 50.5 out of 80 (range: 23-79). A low DISCERN score (≤ 50%) was found in 50% (n = 54) of the websites. The DISCERN score was found to be significantly associated with LIDA usability, reliability, LIDA overall scores (p < 0.001), and HON code certification (p = 0.01). The quality of the websites providing patient-centered information on the Internet ranged between moderate and low with regards to readability, usability, and reliability scores. Better informed decisions on treatment may be facilitated with the access to good quality information online. Therefore, strategies need to be implemented to regulate and standardize websites to provide good quality, accurate information.	esophagus
Role of Immunotherapy in Advanced Gastroesophageal Cancer.	PURPOSE OF REVIEW: Immunotherapy and tumor microenvironment have been at the forefront of cancer research over the past several decades. Here, we will review the role of immunotherapy in advanced gastroesophageal cancers including targeted antibodies, immunomodulating agents, vaccines, oncolytic virus therapy, and adoptive immunotherapy, and discuss the future direction for immunotherapy in this population. RECENT FINDINGS: Targeted antibodies are already standard-of-care. An anti-PD-1 monoclonal antibody is currently FDA approved for second-line treatment of locally advanced or metastatic ESCC, as well as beyond second-line treatment of advanced G/GEJ cancers, and recent data suggests it may be considered in first-line treatment of advanced G/GEJ cancers. Combination therapies such as immunotherapy plus chemotherapy and/or radiotherapy, vaccines, oncolytic viral therapy, and adoptive immunotherapy in varying combinations are currently under active investigation. Several trials are ongoing and are hoped to reach more efficacious and individualized treatment options in advanced gastroesophageal cancer, where novel treatment options are desperately needed.	esophagus
Interaction of Estradiol and Endoplasmic Reticulum Stress in the Development of Esophageal Carcinoma.	Gender differences in esophageal cancer patients indicate that estradiol may have antitumor effects on esophageal cancer. The initiation of endoplasmic reticulum stress (ERS) can induce apoptosis in esophageal cancer cells. However, it is still unknown whether estradiol inhibits the development of esophageal cancer by activating ERS pathway. In this study, the gender difference in the development of esophageal cancer was observed by analyzing clinical data and the experimental tumor xenografts in mice. Meanwhile, we investigated the mechanism of ERS in estradiol-mediated inhibition of esophageal cancer using esophageal squamous cell carcinoma cell line EC109. The proportion of male patients with esophageal cancer was significantly higher than female patients. Meanwhile, male patients were prone to have adventitial invasion. The weight of transplanted tumors in female mice was significantly smaller than that in male mice. In vitro experiments showed estradiol inhibits the viability and migration of EC109 cells by increasing the expression of ERS-related proteins, whereas ERS inhibitor 4-PBA abolished the effects of estradiol. In conclusion, our data demonstrate that sex difference exists in the occurrence of esophageal cancer. Estradiol can inhibit the viability and migration of esophageal cancer cells through the activation of ERS, providing a novel insight for esophageal cancer development, treatment, and prevention.	esophagus
Retrospective analysis of the clinical effects of endoscopic mucosal dissection on treatment of early esophagogastric precancerous lesions.	INTRODUCTION: The purpose of this study was to conduct a retrospective study about the clinical effects of endoscopic mucosal dissection on the treatment of early esophagogastric precancerous lesions. METHODS: A total of 132 patients with early esophagogastric precancerous lesions who were diagnosed and treated with concurrent surgery in our hospital from January 2018 to December 2019 were included in this retrospective study. Patients were divided into endoscopic mucosal resection (EMR) group (n = 58) and endoscopic submucosal dissection (ESD) group (n = 74) according to different surgical methods. The data in the two groups were compared and analyzed in terms of surgical indicators, treatment status and incidence of postoperative complications. RESULTS: There were statistically significant differences between the two groups in the whole block cutting rate, fractional cutting rate and complete cutting rate (P < 0.05). The mean operation time of ESD group was significantly longer than that of EMR group (P < 0.05). There were no significant differences in the intraoperative bleeding rate, blood loss, average specimen area, length of hospital stay and treatment cost between the two groups (P > 0.05). The incidence and recurrence of postoperative complications, including bleeding, perforation and stenosis in the two groups, were observed within 1 year of postoperative follow-up. The incidence of complications in ESD group was slightly higher than that in EMR group, and the local recurrence rate in ESD group was lower than that in EMR group (P > 0.05). CONCLUSION: ESD is an alternative surgical treatment for patients with early esophagogastric precancerous lesions.	esophagus
Outcomes of robotic esophagectomies for esophageal cancer by hospital volume: an analysis of the national cancer database.	BACKGROUND: Robotic minimally invasive esophagectomies (RMIE) have been associated with superior outcomes; however, it is unclear if these are specific to robotic technique or are present only at high-volume institutions. We hypothesize that low-volume RMIE centers would have inferior outcomes. METHODS: The National Cancer Database (NCDB) identified patients receiving RMIE from 2010 to 2016. Based on the total number of RMIE performed by each hospital system, the lowest quartile performed ≤ 9 RMIE over the study period. Ninety-day mortality, number of lymph nodes evaluated, margins status, unplanned readmissions, length of stay (LOS), and overall survival were compared. Regression models were used to account for confounding. RESULTS: 1565 robotic esophagectomies were performed by 212 institutions. 173 hospitals performed ≤ 9 RMIE (totaling 478 operations over the study period, 30.5% of RMIE) and 39 hospitals performed > 9 RMIE (1087 operations, 69.5%). Hospitals performing > 9 RMIE were more likely to be academic centers (90.4% vs 66.2%, p < 0.001), have patients with advanced tumor stage (65.3% vs 59.8%, p = 0.049), andadministered preoperative radiation (72.8% vs 66.3%, p = 0.010). There were no differences based on demographics, nodal stage, or usage of preoperative chemotherapy. On multivariable regressions, hospitals performing ≤ 9 RMIE were associated with a greater likelihood of experiencing a 90-day mortality, a reduced number of lymph nodes evaluated, and a longer LOS; however, there was no association with rates of positive margins or unplanned readmissions. Median overall survival was decreased at institutions performing ≤ 9 RMIE (37.3 vs 51.5 months, p < 0.001). Multivariable Cox regression demonstrated an association with poor survival comparing hospitals performing ≤ 9 to > 9 RMIE (HR 1.327, p = 0.018). CONCLUSION: Many robotic esophagectomies occur at institutions which performed relatively few RMIE and were associated with inferior short- and long-term outcomes. These data argue for regionalization of robotic esophagectomies or enhanced training in lower volume hospitals.	esophagus
Histopathological landscape of rare oesophageal neoplasms.	The landscape of neoplastic pathology of the oesophagus is dominated by malignancies of epithelial origin, in particular by oesophageal adenocarcinoma and oesophageal squamous cell carcinoma. However, several other histopathological variants can be distinguished, some associated with peculiar histopathological profiles and prognostic behaviours and frequently underrecognized in clinical practice. The aim of this review is to provide a comprehensive characterization of the main morphological and clinical features of these rare variants of oesophageal neoplastic lesions.	esophagus
SHCBP1 Promotes the Progression of Esophageal Squamous Cell Carcinoma Via the TGFβ Pathway.	Esophageal cancer (EC) is known as a type of common malignant tumor, with the incidence ranking eighth worldwide. Because of the high metastasis of advanced EC, the total survival rate has been quite low. Esophageal squamous cell carcinoma (ESCC) is a main type of EC. Targeted therapy for ESCC has become a new direction; however, newly therapeutic targets are also badly needed. Shc SH2 domain-binding protein (SHCBP1) is located on 16q11.2, which is a downstream protein of the Shc adaptor. SHCBP1 participates in the regulation of several physiological and pathologic processes, such as cytokinesis. Recent studies have found that SHCBP1 was abnormally upregulated in multiple types of tumors, such as breast cancer and liver cancer, and that it affects the proliferation and motility of cancer cells in vitro. However, it remains unclear whether SHCBP1 is related to the progression of EC. Herein, we found the upregulation of SHCBP1 in human EC tissues. Our findings further demonstrated that SHCBP1 expression was related to the clinical features of ESCC patients. We found that SHCBP1 depletion inhibited the proliferation and motility of ESCC cells via the transforming growth factor β pathway and that it suppressed the growth of tumors in mice. We, therefore, concluded that SHCBP1 could serve as a promising EC molecular target.	esophagus
Esophageal cancer surgery in Greece during the era of the financial crisis.	The aim of this study is to describe outcomes of esophageal cancer surgery in a quaternary upper gastrointestinal (GI) center in Athens during the era of the Greek financial crisis. We performed a retrospective analysis of patients that underwent esophagectomy for esophageal or gastroesophageal junction (GEJ) cancer at an upper GI unit of the University of Athens, during the period January 2004-June 2019. Time-to-event analyses were performed to explore trends in survival and recurrence. A total of 146 patients were identified. Nearly half of the patients (49.3%) underwent surgery during the last 4 years of the financial crisis (2015-2018). Mean age at the time of surgery was 62.3 ± 10.3 years, and patients did not present at older ages during the recession (P = 0.50). Most patients were stage III at the time of surgery both prior to the recession (35%) and during the financial crisis (39.8%, P = 0.17). Ivor-Lewis was the most commonly performed procedure (67.1%) across all eras (P = 0.06). Gastric conduit was the most common form of GI reconstruction (95.9%) following all types of surgery (P < 0.001). Pre-recession anastomoses were usually performed using a circular stapler (65%). Both during (88.1%) and following the recession (100%), the vast majority of anastomoses were hand-sewn. R0 resection was achieved in 142 (97.9%) patients. Anastomosis technique did not affect postoperative leak (P = 0.3) or morbidity rates (P = 0.1). Morbidity rates were not significantly different prior to (25%), during (46.9%), and after (62.5%) the financial crisis, P = 0.16. Utilization of neoadjuvant chemotherapy (26.9%, P = 0.90) or radiation (8.4%, P = 0.44) as well as adjuvant chemotherapy (54.8%, P = 0.85) and irradiation (13.7%, P = 0.49) was the same across all eras. Disease-free survival (DFS) and all-cause mortality rates were 41.2 and 47.3%, respectively. Median DFS and observed survival (OS) were 11.3 and 22.7 months, respectively. The financial crisis did not influence relapse (P = 0.17) and survival rates (P = 0.91). The establishment of capital controls also had no impact on recurrence (P = 0.18) and survival (P = 0.94). Austerity measures during the Greek financial crisis did not influence long-term esophageal cancer outcomes. Therefore, achieving international standards in esophagectomy may be possible in resource-limited countries when centralizing care.	esophagus
Salvage endoscopic resection after definitive chemoradiotherapy for esophageal cancer: a Western experience.	BACKGROUND AND AIMS: Definitive chemoradiotherapy (CRT) is increasingly used as a nonsurgical treatment for esophageal cancer. In Japanese studies, salvage endoscopic resection (ER) has emerged as a promising strategy for local failure after definitive CRT. We aimed to evaluate the safety and efficacy of salvage ER in a Western setting. METHODS: Gastroenterologists from Europe and the United States were invited to submit their experience with salvage endoscopic submucosal dissection (ESD) or endoscopic mucosal resection (EMR) after definitive CRT. Participating gastroenterologists completed an anonymized database, including patient demographics, clinicopathologic variables, and follow-up on survival and recurrence. RESULTS: Gastroenterologists from 10 endoscopic units in 6 European countries submitted information on 25 patients. A total of 35 salvage ER procedures were performed, of which 69% were ESD and 31% EMR. Most patients had squamous cell carcinoma (64%) of the middle or lower esophagus (68%) staged as cT2-3 (68%) and cN+ (52%) before definitive CRT. The median time from end of definitive CRT to ER was 22 months (interquartile range, 6-47). The en-bloc resection rate was 92% for ESD and 46% for EMR. During a median of 24 months (interquartile range, 12-59) of follow-up after salvage ER, 52% developed a recurrence (11 locoregional, 2 distant). The 5-year recurrence-free survival, overall survival, and disease-specific survival were 36%, 52%, and 79%, respectively. No major intra- or postprocedural adverse events, such as bleeding or perforation, were reported. CONCLUSIONS: In carefully selected esophageal cancer patients, salvage ER is technically feasible after definitive CRT. Further prospective research is recommended to validate the safety and effectivity of salvage ER for the management of local failure.	esophagus
Residual disease after neoadjuvant chemoradiotherapy for oesophageal cancer: locations undetected by endoscopic biopsies in the preSANO trial.	BACKGROUND: Active surveillance has been proposed for patients with oesophageal cancer in whom there is a complete clinical response after neoadjuvant chemoradiotherapy (nCRT). However, endoscopic biopsies have limited negative predictive value in detecting residual disease. This study determined the location of residual tumour following surgery to improve surveillance and endoscopic strategies. METHODS: The present study was based on patients who participated in the prospective preSANO trial with adenocarcinoma or squamous cell carcinoma of the oesophagus or oesophagogastric junction treated in four Dutch hospitals between 2013 and 2016. Resection specimens and endoscopic biopsies taken during clinical response evaluations after nCRT were reviewed by two expert gastrointestinal pathologists. The exact location of residual disease in the oesophageal wall was determined in resection specimens. Endoscopic biopsies were assessed for the presence of structures representing the submucosal layer of the oesophageal wall. RESULTS: In total, 119 eligible patients underwent clinical response evaluations after nCRT followed by standard surgery. Residual tumour was present in endoscopic biopsies from 70 patients, confirmed on histological analysis of the resected organ. Residual tumour was present in the resection specimen from 27 of the other 49 patients, despite endoscopic biopsies being negative. Of these 27 patients, residual tumour was located in the mucosa in 18, and in the submucosa beneath tumour-free mucosa in eight. One patient had tumour in muscle beneath tumour-free mucosa and submucosa. CONCLUSION: Most residual disease after nCRT missed by endoscopic biopsies was located in the mucosa. Active surveillance could be improved by more sampling and considering submucosal biopsies.	esophagus
Neoadjuvant chemoradiotherapy plus surgery versus surgery alone for clinical node-negative esophageal carcinoma.	BACKGROUND: The impact of neoadjuvant chemoradiotherapy (nCRT) on early stage esophageal cancer is unknown. Here, we compared the outcomes after esophagectomy alone or nCRT plus surgery for clinically staged node-negative esophageal cancer. METHODS: We searched the Surveillance, Epidemiology, and End Results database for patients with clinically node-negative (cN0) esophageal cancer from 2004 to 2016 who underwent surgery alone or nCRT plus surgery. Propensity score matching and Cox regression analysis were used to identify covariates associated with overall survival and cancer-specific survival. RESULTS: A total of 1587 patients were retrospectively identified, of whom 49.8% (n = 791) received nCRT and 80.2% (n = 1273) were truly node-negative diseases. For the entire cohort, surgery alone was associated with a statistically significant but modest absolute increase in survival outcomes (P < 0.01). After matching, nCRT was associated with improved five-year overall survival for pT3-4N0 (localized) disease (59.6% vs. 37.7%; P < 0.001) and pathological node-positive disease (60.5% vs. 40.7%; P = 0.002). Cox multivariate regression analysis revealed that the addition of nCRT for truly node-negative patients with tumor length ≥ 3 cm, pT1-2N0 (early-staged) and localized disease were independent risk factors for survival than surgery alone (P < 0.01). CONCLUSIONS: Compared with surgery alone, patients with cN0 esophageal cancer with pathological node-positive or localized true node-negative disease gain a significant survival benefit from nCRT. However, nCRT plus surgery was associated with decreased survival for early-staged true node-negative patients. This finding may have significant implications on the use of neoadjuvant chemoradiation in patients with cN0 disease.	esophagus
Outcome after endoscopic treatment for dysplasia and superficial esophageal cancer - a cohort study.	BACKGROUND: Dysplasia and superficial esophageal cancer should initially be treated endoscopically. Little is known about post-procedural health-related quality of life (HRQL). The aim of this study was to present our results with endoscopic treatment and post-procedural HRQL. MATERIALS AND METHODS: From June 2014 to December 2018, all patients treated with endoscopic mucosal resection (EMR) and/or radiofrequency ablation (RFA) for low-grade dysplasia (LGD), high-grade dysplasia (HGD), T1a and a minority of patients with T1b at Oslo University Hospital were prospectively included. In June 2019, all patients alive were scored according to the Ogilvie dysphagia score as well as the QLQ-C30 and QLQ-OG25 for assessment of HRQL. RESULTS: Eighty-six patients were treated out of whom 22 (26%) had LGD, 44 (51%) HGD, 13 (15%) T1a, and six patients (7%) T1b. Histology revealed adenocarcinoma in 18 (21%) and squamous cell carcinoma in one (1%), respectively. The mean follow-up was 22.9 months. Tumor regression or downstaging was archived in 78% of the patients with LGD, 66% of patients with HGD and in 89% of patients with T1a/b. Five patients (6%) had esophagectomy. There were few and no serious complications. The 90-days mortality was 1%. Fifty-two patients (88%) experienced no dysphagia (Ogilvie score 0). There was no difference in 11 out of the 15 variables in QLQ-C30 when compared to a non-cancerous reference population. CONCLUSIONS: Endoscopic treatment is safe and efficient for treatment of dysplasia and superficial esophageal cancer. The two-years post-procedural level of HRQL and dysphagia was satisfactory.	esophagus
A radical change: A qualitative study of patients' experiences of eating and daily living through the first year after oesophageal resection.	PURPOSE: The purpose of this study is to explore the lived experiences of patients in terms of eating and consequences in everyday life in the first year after oesophageal cancer surgery. METHODS: Thirteen patients participated in qualitative interviews one year after surgery for oesophageal cancer. Descriptions capturing the meaning of the lived experiences of patients were then derived from subsequent analysis and interpretation of the interviews. A phenomenological hermeneutical approach comprised the epistemological stance, and theoretical perspectives were drawn from Schutz' theory of everyday life. RESULTS: Patient descriptions of their experiences with food, eating and everyday life in the first year after oesophageal cancer surgery fell into four themes: Adjusting to a different anatomy - food and eating as a dominant and difficult activity; changed body - food and eating as an underlying shadow; feeling different - social consequences of changed eating; a nutritional jungle - guidance and support in an uncertain time. CONCLUSION: The physical and social consequences of oesophageal cancer resection upend everyday structures, requiring patients to adopt a new, conscious and reflexive approach to food and eating as a social activity. Continuous support from healthcare professionals and patient-to-patient interaction can help redefine everyday life.	esophagus
Impact of sex and age on chemotherapy efficacy, toxicity and survival in localised oesophagogastric cancer: A pooled analysis of 3265 individual patient data from four large randomised trials (OE02, OE05, MAGIC and ST03).	BACKGROUND: There is a lack of large-scale randomised data evaluating the impact of sex and age in patients undergoing chemotherapy followed by potentially curative surgery for oesophagogastric cancer. PATIENTS AND METHODS: Individual patient data from four prospective randomised controlled trials were pooled using a two-stage meta-analysis. For survival analysis, hazard ratios (HRs) were calculated for patients aged <70 and ≥ 70 years, as well as between males and females. Mandard tumour regression grade (TRG) and, ≥grade III toxicities were compared using logistic regression models to calculate odds ratios. All analyses were adjusted for the type of chemotherapy received. RESULTS: 3265 patients were included for survival analysis (2668 [82%] male, 597 [18%] female; 2627 (80%) <70 years, 638 (20%) ≥70 years). A significant improvement in overall survival (OS) (HR: 0.78; p < 0.001) and disease-specific survival (DSS) (HR: 0.78; p < 0.001) was observed in females compared with males. No significant differences in OS (HR: 1.11; p = 0.045) or DSS (HR: 1.01; p = 0.821) were observed in older patients compared with younger patients. For patients who underwent resection, older patients (15% vs 10%; p = 0.03) and female patients (14% vs 10%, p = 0.10) were more likely to achieve favourable Mandard TRG scores. Females experienced significantly more ≥grade III nausea (10% vs 5%; p≤0.001), vomiting (10% vs 4%; p≤0.001) and diarrhoea (9% vs 4%; p≤0.001) than males. CONCLUSIONS: In this large pooled analysis using prospective randomised trial data, females had significantly improved survival while experiencing more gastrointestinal toxicities. Older patients achieved comparable survival to younger patients and thus, dependent on fitness, should be offered the same treatment paradigm.	esophagus
