FGFR2 regulation by picrasidine Q inhibits the cell growth and induces apoptosis in esophageal squamous cell carcinoma.	Fibroblast growth factor receptor (FGFR) 2 and its downstream signaling cascades, PI3 K/AKT/mTOR is playing an important role in cell survival and proliferations. In this study, we firstly found that picrasidine Q (PQ), an alkaloid component extracted from Angelica keiskei species, has the capacity of anti-cell transformation and anti-cancer. After ligand shape similarity approach of PQ, we found that PQ targeted FGFR 2 and verified by FGFR2 kinase assay as well as computational docking model. FGFR2 highly expressed in esophageal cancer tissues and PQ inhibited fibroblast growth factor (FGF)-induced cell transformation. Furthermore, PQ inhibited cell proliferation and induced cell cycle arrest and apoptosis in KYSE30, KYSE410, and KYSE450 esophageal squamous cell carcinoma (ESCC) cells. It was confirmed by detecting of biological markers such as cyclinD1, cyclinD3 and cyclinB1 for cell cycle or cleaved caspase-7, caspase-3, and PARP for apoptosis. PQ targeting of FGFR2 kinase activities suppressed downstream target proteins including phosphorylation of AKT and mTOR but not MEK/ERK signaling pathways. Taken together, our results are the first to identify that PQ might be a chemopreventive and chemotherapeutic agent by direct targeting FGFR2 and inhibiting cell proliferation of ESCC cells.	esophagus
Influence of tumor response and treatment schedule on the distribution of tumor recurrence in esophageal cancer patients treated with neoadjuvant chemoradiotherapy.	BACKGROUND AND OBJECTIVES: The impact of different neoadjuvant chemoradiotherapy (nCRT) schedules and pathologic complete response (pCR) on the distribution of recurrence is unclear in esophageal cancer (EC). We assessed the effect of pCR and nCRT schedule in EC. METHODS: Patients with T1N+/T2-4aN0-3/M0 EC treated in different centers, with either carboplatin/paclitaxel/41.4 Gy (CROSS: n = 134) or Cisplatin/5-fluorouracil/45-50.4 Gy (Cis/5FU: n = 88) followed by surgery were included. The effect of pCR on distribution and site-specific recurrence was determined for the CROSS group. After propensity score matching we compared the impact of both schedules (n = 63 each) on the recurrence pattern. RESULTS: Overall (P = 0.005) and disease-free survival (P = 0.002) were significantly longer after pCR (n = 24). The pattern of recurrence differed between pCR and non-pCR group (P = 0.001) for locoregional (0 vs 7; 6.4%), distant (5; 20.8% vs 36; 32.7%), and combined local and distant (0 vs 21; 19.1%), respectively. After pCR, less local and distant recurrences were seen (P = 0.008). With equal median time to recurrence, the distribution of metastases only differed for lung metastases (P = 0.029), with 15 (23.8%) in the CROSS group versus 6 (9.5%) following Cis/5FU. CONCLUSIONS: Patients with pCR have less local and distant recurrence. The nCRT regime had a minor influence on the site-specific distribution of recurrence.	esophagus
Serum Autoantibodies against STIP1 as a Potential Biomarker in the Diagnosis of Esophageal Squamous Cell Carcinoma.	Esophageal squamous cell carcinoma (ESCC) remains one of the leading causes of cancer-related mortality around the world. The identification of novel serum biomarkers is required for early detection of ESCC. This study was designed to elucidate whether autoantibodies against STIP1 could be a diagnostic biomarker in ESCC. An enzyme-linked immunosorbent assay was performed to detect serum levels of STIP1 autoantibodies in a training cohort (148 ESCC patients and 111 controls) and a validation cohort (60 ESCC patients and 40 controls). Mann-Whitney's U test showed that ESCC patients in two cohorts have higher levels of autoantibodies against STIP1 when compared to controls (P < 0.001). According to receiver operating characteristic analysis, the sensitivity, specificity, and area under the curve (AUC) of autoantibodies against STIP1 in ESCC were 41.9%, 90.1%, and 0.682 in the training cohort and 40.0%, 92.5%, and 0.710 in the validation cohort, respectively. Moreover, detection of autoantibodies against STIP1 could discriminate early-stage ESCC patients from controls, with sensitivity, specificity, and AUC of 35.7%, 90.1%, and 0.684 in the training cohort and 38.5%, 92.5%, and 0.756 in the validation cohort, respectively. Our findings indicated that autoantibodies against STIP1 might be a useful biomarker for early-stage ESCC detection.	esophagus
Automatic treatment planning facilitates fast generation of high-quality treatment plans for esophageal cancer.	BACKGROUND: The quality of radiotherapy planning has improved substantially in the last decade with the introduction of intensity modulated radiotherapy. The purpose of this study was to analyze the plan quality and efficacy of automatically (AU) generated VMAT plans for inoperable esophageal cancer patients. MATERIAL AND METHODS: Thirty-two consecutive inoperable patients with esophageal cancer originally treated with manually (MA) generated volumetric modulated arc therapy (VMAT) plans were retrospectively replanned using an auto-planning engine. All plans were optimized with one full 6MV VMAT arc giving 60 Gy to the primary target and 50 Gy to the elective target. The planning techniques were blinded before clinical evaluation by three specialized oncologists. To supplement the clinical evaluation, the optimization time for the AU plan was recorded along with DVH parameters for all plans. RESULTS: Upon clinical evaluation, the AU plan was preferred for 31/32 patients, and for one patient, there was no difference in the plans. In terms of DVH parameters, similar target coverage was obtained between the two planning methods. The mean dose for the spinal cord increased by 1.8 Gy using AU (p = .002), whereas the mean lung dose decreased by 1.9 Gy (p < .001). The AU plans were more modulated as seen by the increase of 12% in mean MUs (p = .001). The median optimization time for AU plans was 117 min. CONCLUSIONS: The AU plans were in general preferred and showed a lower mean dose to the lungs. The automation of the planning process generated esophageal cancer treatment plans quickly and with high quality.	esophagus
[Use of gastric tube in construction technique thoracoscopic and laparoscopic Ivor-Lewis esophagectomy].	OBJECTIVE: To discuss the safety and feasibility of gastric tube in construction technique in total thoracoscopic and laparoscopic Ivor-Lewis esophagectomy. METHODS: Clinical data of 358 patients with esophageal cancer who underwent the Ivor-Lewis procedure by the same surgical team in our department from June 2015 to June 2016 were retrospectively analyzed. Patients were divided into two groups: group MI (mini-incision): 92 patients undergoing extracorporeally gastric tube through a 4-cm abdominal mini-incision after gastric mobilization; group TL (total laparoscopy): 266 patients undergoing gastric tube made by total laparoscopy and jejunostomy. Intra-operative and postoperative data were compared between two groups. RESULTS: Of 358 patients, 290 were male and 68 were female. The average age was (62.3±15.6) years. The tumor location ratio of group TL and group MI was 27.1%(72/266) and 25.0%(23/92) in middle thoracic esophageal cancer, 35.3%(94/266) and 34.8%(32/92) in mid-lower thoracic esophageal cancer, and 37.6%(100/266) and 40.2%(37/92) in lower thoracic esophageal cancer, respectively. In group TL and group MI, 42.1% (112/266) and 46.7%(43/92) patients were stage I( to II(a; 57.9%(154/266) and 53.3%(49/92) patients were stage II(b to III(a, respectively. All the patients from two groups received successful Ivor-Lewis esophagectomy. There were no significant differences between group TL and MI in operative time [abdominal operative time: (65.6±25.8) min vs. (62.3±25.6) min; thoracic operative time: (180.3±37.4) min vs. (178.1±39.2) min; time of making gastric tube:(16.1±3.2) min vs.(15.7±3.5) min], blood loss [abdominal: (60.5±19.8) ml vs. (62.3±20.9) ml; thoracic: (228.7±47.3) ml vs. (231.6±46.8) ml], and the number of lymph nodes dissection (abdominal: 8.9±1.8 vs. 8.7±1.6; mediastinal: 21.2±3.6 vs. 20.8±3.8)(all P>0.05). And there were no significant differences in occurrence of postoperative anastomotic leakage [4.5%(12/266) vs. 4.3%(4/92), χ(2)=0.845, P=0.948], postoperative hospital stay [(12.2±4.8) d vs. (13.1±5.1) d, t=1.525, P=0.128] and average hospitalization cost(5.5±2.1 vs. 5.3±1.2, t=0.865, P=0.172) (ten thousand yuan, RMB) between group TL and MI. CONCLUSION: During minimally invasive Ivor-Lewis esophagectomy, gastric tube by total laparoscopy is safe and reliable.	esophagus
Recurrence patterns and associated factors of locoregional failure following neoadjuvant chemoradiation and surgery for esophageal cancer.	BACKGROUND: Despite neoadjuvant chemoradiation (nCRT) followed by esophagectomy for locally advanced esophageal cancer, locoregional recurrence (LRR) is common and factors associated with LRR have not been clearly identified. METHODS: Patients were identified from a single institution, prospectively maintained database (1996-2013). Patterns of recurrence were described and associated factors of LRR were analyzed using competing risks regression models. RESULTS: Of the 456 patients treated with nCRT and surgery, 167 patients developed recurrence. Locoregional and distant recurrences were observed in 69 (15.1%) and 140 (30.9%) patients, respectively. Time to recurrence (13.6 vs 10.4 months, P = 0.20) and median overall survival (29.3 vs 19.1 months, P = 0.12) were no different among the 27 patients (6%) who developed a solitary LRR compared to patients who developed distant recurrence. Univariable analysis identified lymphovascular invasion (HR 1.46, P = 0.07), lymph node ratio >0.5 (HR 2.16, P = 0.02), positive margin (HR 1.95, P = 0.05), lack of response to neoadjuvant therapy (HR 1.99, P < 0.01), clinical T stage (HR 2.62, P < 0.01) and final T3/4 stage (HR 2.06, P < 0.01) as factors significantly associated with LRR. Clinical T stage and response to neoadjuvant treatment were independently associated with LRR on multivariable analysis. CONCLUSIONS: Although aggressive tumor biology plays a significant role in LRR, optimizing neoadjuvant treatments to obtain a complete pathologic response may lead to improved locoregional control.	esophagus
Racial disparities in cancer-related survival in patients with squamous cell carcinoma of the esophagus in the US between 1973 and 2013.	BACKGROUND: Esophageal cancer makes up approximately 1% of all diagnosed cancers in the US. There is a persistent disparity in incidence and cancer-related mortality rates among different races for esophageal squamous cell carcinoma (SCC). Most previous studies investigated racial disparities between black and white patients, occasionally examining disparities for Hispanic patients. Studies including Asians/Pacific Islanders (API) as a subgroup are rare. Our objective was to determine whether there is an association between race and cancer-related survival in patients with esophageal SCC. METHODS AND FINDINGS: This was a retrospective cohort study using the National Cancer Institute's Surveillance, Epidemiology, and End Result (SEER) database. The SEER registry is a national database that collects information on all incident cancer cases in 13 states of the United States and covers nearly 26% of the US population Patients aged 18 and over of White, Black, or Asian/Pacific Islander (API) race with diagnosed esophageal SCC from 1973 to 2013 were included (n = 13,857). To examine overall survival, Kaplan-Meier curves were estimated for each race and the log-rank test was used to compare survival distributions. Cox proportional hazards models were used to estimate unadjusted and adjusted hazard ratios with 95% confidence intervals. The final adjusted model controlled for sex, marital status, age at diagnosis, decade of diagnosis, ethnicity, stage at diagnosis, and form of treatment. Additional analyses stratified by decade of diagnosis were conducted to explore possible changes in survival disparities over time. After adjustment for potential confounders, black patients had a statistically significantly higher hazard ratio compared to white patients (HR 1.08; 95% confidence interval (CI) 1.03-1.13). However, API patients did not show a statistically significant difference in survival compared with white patients (HR 1.00; 95% CI 0.93-1.07). Patients diagnosed between 1973 and 1979 had twice the hazard of death compared to those diagnosed between 2000 and 2013 (HR 2.05, 95% CI 1.93-2.19). Patients diagnosed in 1980-1989 and 1990-1999 had had HRs of 1.59 (95% CI 1.51-1.68) and 1.33 (95% CI 1.26-1.41), respectively. After stratification according to decade of diagnosis, the HR for black patients compared with white patients was 1.14 (95% CI 1.02-1.29) in 1973-1979 and 1.12 (95% CI 1.03-1.23) in 1980-1989. These disparities were not observed after 1990; the HR for black patients compared with white patients was 1.03 (95% CI 0.93-1.13) in 1990-1999 and 1.05 (95% CI 0.96-1.15) in 2000-2013. CONCLUSIONS: Black patients with esophageal SCC were found to have a higher hazard of death compared to white and API patients. Survival disparities between races appear to have decreased over time. Future research that takes insurance status and other social determinants of health into account should be conducted to further explore possible disparities by race.	esophagus
Epidemiology of Esophageal Squamous Cell Carcinoma.	Esophageal squamous cell carcinoma (ESCC) accounts for about 90% of the 456,000 incident esophageal cancers each year. Regions of high incidence include Eastern to Central Asia, along the Rift Valley in East Africa, and into South Africa. There are many causes of ESCC, which vary among regions. Early studies in France associated smoking cigarettes and heavy alcohol consumption with high rates of ESCC, but these factors cannot explain the high incidence in other regions. We discuss other risk factors for ESCC, including polycyclic aromatic hydrocarbons from a variety of sources, high-temperature foods, diet, and oral health and the microbiome-all require further research. A growing list of defined genomic regions affects susceptibility, but large genome-wide association studies have been conducted with ethnic Chinese subjects only; more studies are called for in the rest of Asia and Africa. ESCC has been understudied, but growing infrastructure in more high-incidence countries will allow rapid progress in our understanding.	esophagus
Down-regulation of XIAP enhances the radiosensitivity of esophageal cancer cells in vivo and in vitro.	The study investigated the effects of X-chromosome-linked inhibitor of apoptosis (XIAP) gene silencing on the radiosensitivity of esophageal cancer (EC) cells. Western blotting was used to select EC cell lines with XIAP overexpression. Selected EC9706 and KYSE30 cell lines were both divided into four groups: the blank control group, the negative control (NC) group (transfected with pBSHH1), the siRNA-enhanced group (transfected with pBSHH1-XIAP1-siRNA), and the siRNA-decreased group (transfected with pBSHH1-XIAP2-siRNA). Expressions of XIAP were measured by reverse-transcription quantitative PCR (RT-qPCR) and Western blotting, cell survival and viability by MTT assay and colony formation assay, and cell apoptosis by flow cytometry, respectively. Caspase-3 and caspase-9 activity were detected using caspase-3 and caspase-9 activity detection kits. A nude mice model of EC9706 cell line was established to measure tumorigenesis ability. Compared with the NC group, XIAP mRNA and protein expressions were decreased, caspase-3 and caspase-9 activity and apoptosis were up-regulated, and cell survival rate and colony-forming efficiency were lower in the siRNA-enhanced and siRNA-decreased groups in both the cell lines; while the opposite trends were found in the siRNA-decreased group compared with the siRNA-enhanced group. Tumor weight and volume of nude mice were decreased in the siRNA-enhanced and siRNA-decreased groups than those in the NC group, and were elevated in the siRNA-decreased group compared with the siRNA-enhanced group. These results indicate that XIAP gene silencing would strengthen the radiosensitivity of EC9706 cells, which provides a novel target for the treatment of EC.	esophagus
Physical ExeRcise Following Esophageal Cancer Treatment (PERFECT) study: design of a randomized controlled trial.	BACKGROUND: Following esophagectomy, esophageal cancer patients experience a clinically relevant deterioration of health-related quality of life, both on the short- and long-term. With the currently growing number of esophageal cancer survivors, the burden of disease- and treatment-related complaints and symptoms becomes more relevant. This emphasizes the need for interventions aimed at improving quality of life. Beneficial effects of post-operative physical exercise have been reported in several cancer types, but so far comparable evidence in esophageal cancer patients is lacking. The aim of this study is to investigate effects of physical exercise on health-related quality of life in esophageal cancer patients following surgery. METHODS: The Physical ExeRcise Following Esophageal Cancer Treatment (PERFECT) study is a multicenter randomized controlled trial including 150 esophageal cancer patients after surgery with curative intent. Patients are randomly allocated to an exercise group or usual care group. The exercise group participates in a 12-week combined aerobic and resistance exercise program, supervised by a physiotherapist near the patient's home-address. In addition, participants in the exercise group are requested to be physically active for at least 30 min per day, every day of the week. Participants allocated to the usual care group are asked to maintain their habitual physical activity pattern. The primary outcome is health-related quality of life (EORTC-QLQ-C30). Secondary outcomes include esophageal cancer specific quality of life, fatigue, anxiety and depression, sleep quality, work-related factors, cardiorespiratory fitness (VO(2peak)), muscle strength, physical activity, malnutrition risk, anthropometry, blood markers, recurrence of disease and survival. All questionnaire outcomes, diaries and accelerometers are assessed at baseline, post-intervention (12 weeks post-baseline) and 24 weeks post-baseline. Physical fitness, anthropometry and blood markers are assessed at baseline and post-intervention. In addition, adherence and safety are monitored throughout the exercise program. DISCUSSION: This randomized controlled trial investigates effects of physical exercise versus usual care in esophageal cancer patients after surgery. As the design of the exercise program closely resembles daily practice, this study can contribute both to evidence on effects of exercise in esophageal cancer patients, and to potential implementation strategies.

Ablation Therapy for Barrett's Esophagus: New Rules for Changing Times.	PURPOSE OF REVIEW: In this review, we discuss different endoscopic techniques in the eradication of Barrett's esophagus (BE) as well as some controversies in the field of treatment. RECENT FINDINGS: Patients with T1a esophageal adenocarcinoma and BE of high-grade dysplasia should undergo endoscopic ablative therapy. The most studied technique to date is radiofrequency ablation. It can be combined with endoscopic mucosal resection in cases containing nodular and flat lesions. Cryotherapy and APC have shown promise with good efficacy and safety profiles so far, but are not mainstream as more studies are needed. Surveillance is still required post-ablation since recurrence is common. Low-grade dysplasia can be treated with either endo-ablative therapy or surveillance. Non-dysplastic BE treatment is controversial and so far, only surveillance is recommended. Research is ongoing to better risk stratify these patients. Our ability to diagnose and treat BE has come a long way in the past few years with the goal of preventing its progression into malignancy. The advent of endoscopic techniques in the eradication of BE has provided a less invasive and safer modality of treatment as compared to surgical esophagectomy. Data in the form of randomized trials and high-volume registries has provided good evidence to support the efficacy of these techniques and their long-term durability.	esophagus
Effect of perioperative oral care on prevention of postoperative pneumonia associated with esophageal cancer surgery: A multicenter case-control study with propensity score matching analysis.	The aim of this study was to investigate the effectiveness of oral care in prevention of postoperative pneumonia associated with esophageal cancer surgery.Postoperative pneumonia is a severe adverse event associated with esophageal cancer surgery. It is thought to be caused by aspiration of oropharyngeal fluid containing pathogens. However, the relationship between oral health status and postoperative pneumonia has not been well investigated.This study included 539 patients with esophageal cancer undergoing surgery at 1 of 7 university hospitals. While 306 patients received perioperative oral care, 233 did not. Various clinical factors as well as occurrence of postoperative pneumonia were retrospectively evaluated. Propensity-score matching was performed to minimize selection biases associated with comparison of retrospective data between the oral care and control groups. Factors related to postoperative pneumonia were analyzed by logistic regression analysis.Of the original 539 patients, 103 (19.1%) experienced postoperative pneumonia. The results of multivariate analysis of the 420 propensity score-matched patients revealed longer operation time, postoperative dysphagia, and lack of oral care intervention to be significantly correlated with postoperative pneumonia.The present findings demonstrate that perioperative oral care can reduce the risk of postoperative pneumonia in patients undergoing esophageal cancer surgery.	esophagus
Lymphocyte Nadir and Esophageal Cancer Survival Outcomes After Chemoradiation Therapy.	PURPOSE: Host immunity may affect the outcome in patients with esophageal cancer. We sought to identify factors that influenced absolute lymphocyte count (ALC) nadir during chemoradiation therapy (CRT) for esophageal cancer (EC) and looked for clinically relevant associations with survival. METHODS AND MATERIALS: 504 patients with stage I-III EC (2007-2013) treated with neoadjuvant or definitive CRT with weekly ALC determinations made during treatment were analyzed. Grade of lymphopenia from ALC nadir during CRT was based on Common Terminology Criteria for Adverse Events version 4.0. Associations of ALC nadir with survival were examined using multivariate Cox proportional hazards analysis (MVA) and competing risks regression analysis. RESULTS: The median follow-up time was 36 months. The incidences of grade 1, 2, 3, and 4 ALC nadir during CRT were 2%, 12%, 59%, and 27%, respectively. The impact was lymphocyte-specific because this was not seen for monocyte or neutrophil count. On MVA, grade 4 ALC nadir (G4 nadir) was significantly associated with worse overall and disease-specific survival outcomes. Predictors of G4 nadir included distal tumor location, definitive CRT, taxane/5-fluorouracil chemotherapy, and photon-based radiation type (vs proton-based). Radiation type strongly influenced the mean body dose exposure, which was a strong predictor for G4 nadir (odds ratio 1.22 per Gray, P<.001). CONCLUSIONS: G4 nadir during CRT for EC was associated with poor outcomes, suggesting a role of host immunity in disease control. This observation provides a rationale to prospectively test chemotherapeutic and radiation treatment strategies that may have a lower impact on host immunity.	esophagus
