A Novel Prognostic Scoring System Using Inflammatory Response Biomarkers for Esophageal Squamous Cell Carcinoma.	BACKGROUND: We describe a novel scoring system, namely the inflammatory response biomarker (IRB) score. The aim of this study is to evaluate the clinical value of IRB score in patients undergoing curative resection for esophageal squamous cell carcinoma (SCC). METHODS: We retrospectively reviewed patients who underwent curative esophagectomy. We evaluated IRB score in both non-elderly (<70 years) and elderly (≥70 years) SCC patients. The IRB score was determined as follows: a high lymphocyte-to-monocyte ratio (LMR) (>4), a high neutrophil-to-lymphocyte ratio (NLR) (>1.6), and a low platelet-to-lymphocyte ratio (PLR) (<147) were each scored as 1, and the remaining values were scored as 0; the individual scores were then summed to produce the IRB score (range 0-3). RESULTS: Univariate analyses demonstrated that the TNM pStage (p < 0.0001), tumor size (p = 0.002), LMR (p = 0.0057), PLR (p = 0.0328) and IRB score (p = 0.0003) were significant risk factors for a worse prognosis. On multivariate analysis, the TNM pStage (p < 0.0001) and IRB score (p = 0.0227) were independently associated with worse prognosis in overall patients. Among non-elderly patients, multivariate analyses demonstrated that the pStage (p = 0.0015) and IRB score (p = 0.0356) were independent risk factors for a worse prognosis. Among elderly patients, multivariate analysis demonstrated that the pStage (p = 0.0016), and IRB score (p = 0.0102) were independent risk factors for a worse prognosis. CONCLUSION: The present study provides evidence that the preoperative IRB score can be considered a promising independent prognostic factor of cancer-specific survival in patients undergoing curative resection for SCC, and that its predictive ability is useful in both non-elderly and elderly patients.	esophagus
Oesophageal cancer: RNA editing of SLC22A3 mRNAs: causative relevance to familial ESCC?	A new study reveals an involvement of SLC22A3 in the development of familial oesophageal squamous cell carcinoma (ESCC). Reduced expression of SLC22A3 is detected not only in ESCC tumours but also in non-tumour tissues of patients with familial ESCC. Interestingly, adenosine-to-inosine editing of SLC22A3 mRNA is proposed to drive early tumour invasion and metastasis, by inhibiting SLC22A3 expression.	esophagus
Impact of Extracapsular Lymph Node Involvement After Neoadjuvant Chemoradiation Therapy Followed by Surgery in Carcinoma of the Esophagus: A Multicenter Study.	OBJECTIVES: The current study aims to examine the impact of extracapsular lymph node involvement (EC-LNI) on survival for both esophageal adenocarcinoma (AC) and squamous cell carcinoma (SCC) treated with neoadjuvant chemoradiation therapy (nCRT) followed by surgery. BACKGROUND: Studies have demonstrated the negative prognostic value of EC-LNI in primary surgery, but its impact after nCRT remains unclear. METHODS: From the databases of 6 European high-volume centers 1505 patients with R0 resections were withheld. Oncologic variables, including ypT, ypN, number of positive lymph nodes, and lymph node capsular status: EC-LNI and intracapsular lymph node involvement (IC-LNI), were examined. Statistical analysis was performed by Cox proportional hazards modeling. RESULTS: In SCC 182 patients (31.6%) had positive lymph nodes, of whom 60 (33.0%) showed EC-LNI. In AC 391 patients (42.1%) had positive lymph nodes, of whom 147 (37.6%) showed EC-LNI. Overall 5-year survival (O5YS) in SCC was 42.0%. Presence of EC-LNI meant a significantly worse O5YS than IC-LNI or pN0 (10.6%, 39.5%, and 47.4%, respectively; P < 0.05). O5YS in AC was 41.2%. No significant difference was observed between EC-LNI and IC-LNI (P = 0.322). In the multivariate analysis, among the examined possible prognosticators, presence of EC-LNI showed the highest hazard ratio (2.29, confidence interval: 1.52-3.47) as an independent prognosticator for overall survival in SCC, but it was not in AC. CONCLUSIONS: Based on this international multicenter study, the presence of EC-LNI after nCRT is at least as important as N-stage for survival and EC-LNI is the strongest prognosticator for overall survival in SCC but not in AC.	esophagus
Survival Benefit of Neoadjuvant Treatment in Clinical T3N0M0 Esophageal Cancer: Results From a Retrospective Multicenter European Study.	BACKGROUND: Based on current guidelines, clinical T3N0M0 esophageal tumors may or may not receive neoadjuvant treatment, according to their perception as locally advanced (cT3) or early-stage tumors (stage II). The study aim was to assess the impact of neoadjuvant treatment upon survival for cT3N0M0 esophageal cancer patients, with subgroup analyses by histological type (squamous cell carcinoma vs adenocarcinoma) and type of neoadjuvant treatment (chemotherapy vs radiochemotherapy). METHODS: Data from patients operated on for esophageal cancer in 30 European centers were collected. Among the 382 of 2944 patients with clinical T3N0M0 stage at initial diagnosis (13.0%), we compared those treated with primary surgery (S, n = 193) versus with neoadjuvant treatment plus surgery (NS, n = 189). RESULTS: The S and NS groups were similar regarding their demographic and surgical characteristics. In-hospital postoperative morbidity and mortality rates were comparable between groups. Patients were found to be pN+ in 64.2% versus 42.9% in the S and NS groups respectively (P < 0.001), pN2/N3 in 35.2% versus 21.2% (P < 0.001), stage 0 in 0% versus 16.4% (P < 0.001), and R0 in 81.3% versus 89.4% of cases (P = 0.026). Median overall and disease-free survivals were significantly better in the NS group, 38.4 versus 27.9 months (P = 0.007) and 31.6 versus 27.5 months (P = 0.040), respectively, and this difference remained for both histological types. Radiotherapy did not offer a benefit compared with chemotherapy alone (P = 0.687). In multivariable analysis, neoadjuvant treatment was an independent favorable prognostic factor (HR 0.76, 95% CI 0.58-0.99, P = 0.044). CONCLUSION: Neoadjuvant treatment offers a significant survival benefit for clinical T3N0M0 esophageal cancer.	esophagus
Are Thoracotomy and/or Intrathoracic Anastomosis Still Predictors of Postoperative Mortality After Esophageal Cancer Surgery?: A Nationwide Study.	BACKGROUND: Intrathoracic (vs cervical) anastomosis and a thoracotomy (vs absence) have previously been associated with increasing postoperative mortality (POM). Recent improvements in surgical practices and perioperative management may have changed these dogmas. OBJECTIVES: The aim of this study was to evaluate the impact of performing intrathoracic anastomosis and/or thoracotomy on POM after esophageal cancer surgery in recent years. METHODS: All consecutive patients who underwent esophageal cancer surgery with reconstruction between 2010 and 2012 in France were included (n = 3286). Patients with a thoracoscopic approach were excluded (n = 4). We compared 30-day POM between patients having received intrathoracic (vs cervical) anastomosis and between those having received a thoracotomy or not. Multivariate analyses and propensity score matching were used to adjust for confounding factors. RESULTS: Patients had either cervical (n = 548) or intrathoracic (n = 2738) anastomosis. Thirty-day POM was higher after cervical anastomosis (8.8% vs 4.9%, P < 0.001). Having received a thoracotomy (n = 3061) was associated with a decreased risk of 30-day POM (5.3% vs 9.3%, P = 0.011). After adjustment for confounding factors, cervical anastomosis was associated with 30-day POM [odds ratio (OR) 1.71; 95% confidence interval (CI) 1.05-2.77); P = 0.032], whereas performing a thoracotomy was not associated with 30-day POM (OR 0.97; 95% CI 0.51-1.84; P = 0.926). CONCLUSIONS: Nowadays, intrathoracic anastomosis provides a lower 30-day POM rate compared to cervical anastomosis, and performing a thoracotomy is not associated with POM. Systematic anastomosis neck placement or thoracotomy avoidance is not a relevant argument anymore to decrease POM.	esophagus
Impact of Lymph Node Yield on Overall Survival in Patients Treated With Neoadjuvant Chemoradiotherapy Followed by Esophagectomy for Cancer: A Population-based Cohort Study in the Netherlands.	OBJECTIVE: To evaluate the impact of lymph node yield (LNY) on survival in patients treated with neoadjuvant chemoradiotherapy (nCRT) followed by esophagectomy for cancer. BACKGROUND: The value of an extended lymphadenectomy after nCRT for esophageal cancer is debated. Recent reports demonstrate no association between LNY and survival. This association has not yet been evaluated in larger cohorts. METHODS: All patients who underwent nCRT followed by esophagectomy between 2005 and 2014 were identified from the Netherlands Cancer Registry. The association between LNY and overall survival was analyzed using multivariable Cox regression analyses, adjusting for diagnosis year, referral, hospital volume, age, sex, malignancy history, tumor location, histology, cTN-stage, surgical approach, radicality, and ypTN-stage. Analyses were performed with LNY as categorized predictor (<15 vs ≥15 nodes) and continuous predictor (per 10 additionally nodes). RESULTS: A total of 2698 patients were included with a median overall survival of 34 months (range 4-143). A higher LNY was significantly associated with improved overall survival, both as categorized predictor (hazard ratio 0.77, 95% confidence interval 0.68-0.86) and as continuous predictor (hazard ratio 0.84, 95% confidence interval 0.78-0.90). Furthermore, a higher LNY was associated with favorable hazard ratios across subgroups, including both squamous cell carcinoma and adenocarcinoma, both cN0 and cN+, both transthoracic and transhiatal approaches, and both ypN0 and ypN+. CONCLUSIONS: This large population-based cohort study demonstrates an association between LNY and overall survival, indicating a therapeutic value of extended lymphadenectomy during esophagectomy. Therefore, an extended lymphadenectomy should be the standard of care after nCRT.	esophagus
Recurrence Patterns and Long-term Results After Induction Chemotherapy, Chemoradiotherapy, and Curative Surgery in Patients With Locally Advanced Esophageal Cancer.	OBJECTIVE: The long-term follow up data of 2 prospective phase II trials is reported (NCT00072033, NCT00445861), which investigated neoadjuvant chemoradiation followed by surgery in patients with esophageal carcinoma. Postoperative complications as well as prognostic factors and patterns of relapse during long-term observation are shown. SUMMARY OF BACKGROUND DATA: Long-term follow-up is often missing in the complex setting of multimodal treatments of esophageal carcinoma; this leads to rather undifferentiated follow-up guidelines for this tumor entity. METHODS: In the first trial, patients received induction chemotherapy followed by chemoradiation and surgery. In the second trial, cetuximab was added to the same neoadjuvant treatment concomitant with induction chemotherapy and chemoradiation. RESULTS: Eighty-two patients underwent surgery; the median follow-up time was 6.8 and 6.4 years, respectively. Fifty-five percent were diagnosed with adenocarcinoma, 80% clinically node-positive, 68% received transthoracic esophagectomy, and 32% transhiatal or transmediastinal resection. Five patients died postoperatively in-hospital due to complications (6%). The median overall survival was 4.3 years, and the median event-free survival was 2.7 years. Patients with adenocarcinoma rarely relapsed after a 3-year event-free survival. Whereas patients with residual tumor cells after neoadjuvant therapy primarily experienced relapse within the first 2 postoperative years, this in contrast to several patients with complete remission who also experienced late relapses 4 years after surgery. CONCLUSION: After curative surgery in a multimodal setting, the histological type and the response to neoadjuvant therapy predicted the time frame of relapse; this knowledge may influence further follow-up guidelines for esophageal carcinoma.	esophagus
Systematic Review and Meta-Analysis of Epidural Analgesia Versus Different Analgesic Regimes Following Oesophagogastric Resection.	INTRODUCTION: Effective analgesia following open oesophagogastric (OG) resection is considered a key determinant of recovery. This review aimed to compare epidural to alternative analgesic techniques in patients undergoing major open resection for OG cancer. METHODS: A systematic review and meta-analysis was conducted of randomized controlled trials comparing epidural with alternative analgesic methods in open OG surgery. Primary outcome was the overall post-operative morbidity rate. Secondary outcomes included pulmonary complication rates, length of stay (LOS) and pain scores at 24 h. RESULTS: Six trials which comprised of 249 patients were identified (3 following gastrectomy and 3 following oesophagectomy). Following gastrectomy, secondary outcomes including pulmonary complications and dynamic pain scores at 24 h were improved in the epidural groups. No difference was observed in overall morbidity rates or LOS. Following oesophagectomy, overall morbidity rates were not reported at all. LOS was not shortened, and rest pain was not significantly different in the epidural group, but dynamic pain scores were reported to be improved. CONCLUSION: Few trials of analgesic regimen have been performed following open OG resection. In those trials that have been performed, epidural analgesia has not been shown to reduce overall morbidity. Epidural is associated with reduced pulmonary complications after gastrectomy, but no benefit has been shown after oesophagectomy. Whilst widespread investigation of minimally invasive OG techniques currently takes place, it is clear that the most effective patient pathway following open OG surgery, particularly oesophagectomy, is still not proven. Further trials are required.	esophagus
Postoperative follow-up programs improve survival in curatively resected gastric and junctional cancer patients: a propensity score matched analysis.	BACKGROUND: To date there is no evidence that more intensive follow-up after surgery for esophagogastric adenocarcinoma translates into improved survival. This study aimed to evaluate the impact of standardized surveillance by a specialized center after resection on survival. METHODS: Data of 587 patients were analyzed who underwent curative surgery for esophagogastric adenocarcinoma in our institution. Based on their postoperative surveillance, patients were assigned to either standardized follow-up (SFU) by the National Center for Tumor Diseases (SFU group) or individual follow-up by other physicians (non-SFU group). Propensity score matching (PSM) was performed to compensate for heterogeneity between groups. Groups were compared regarding clinicopathological findings, recurrence, and impact on survival before and after PSM. RESULTS: Of 587 patients, 32.7% were in the SFU and 67.3% in the non-SFU group. Recurrence occurred in 39.4% of patients and 92.6% within the first 3 years; 73.6% were treated, and of those 17.1% underwent resection. In recurrent patients overall and post-recurrence survival (OS/PRS) was influenced by diagnostic tools (p < 0.05), treatment (p ≤ 0.001), and resection of recurrence (p ≤ 0.001). Standardized follow-up significantly improved OS (84.9 vs. 38.4 months, p = 0.040) in matched analysis and was an independent positive predictor of OS before and after PSM (p = 0.034/0.013, respectively). CONCLUSION: After PSM, standardized follow-up by a specialized center significantly improved OS. Cross-sectional imaging and treatment of recurrence were associated with better outcome. Regular follow-up by cross-sectional imaging especially during the first 3 years should be recommended by national guidelines, since early detection might help select patients for treatment of recurrence and even resection in few designated cases.	esophagus
Relationship of Th17/Treg Cells and Radiation Pneumonia in Locally Advanced Esophageal Carcinoma.	BACKGROUND/AIM: Radiation pneumonia is a main side-effect that has limited the clinical usage of radiotherapy in locally advanced esophageal carcinoma. T helper cells 17 (Th 17) and T regulatory cells (Tregs) play an important role in inflammatory diseases. The balance between Treg and Th17 cells is a key factor in the progression of many inflammatory and autoimmune diseases. Whether Tregs and Th17 cells are predictive factors of radiation pneumonia has not yet been reported. In this study, we investigated the relationships of Treg/Th17 cells and radiation pneumonia in patients with locally advanced esophageal cancer who received radiotherapy. PATIENTS AND METHODS: One hundred and forty-eight patients with locally advanced esophageal cancer who received radical and palliative radiotherapy were enrolled. The levels of Th17 and Treg cells in the blood of patients were detected using flow cytometry at the time point of pre-radiotherapy, 1st, 2nd, 3rd, 4th, 5th and 6th week from the start of radiation and 4 weeks after completion of radiotherapy. Radiation pneumonia was evaluated according to Radiation Therapy Oncology Group's acute radiation pneumonia standards, with the endpoint being grade 2 or above radiation pneumonia. RESULTS: There were 24 cases of radiation pneumonia in 148 cases of locally advanced esophageal cancer patients who underwent radiotherapy. Th17 cells increased and, in contrast, Treg cells decreased in the radiation pneumonia group. The change in the ratio of Th17/Treg was more pronounced and the difference was statistically significant from the 5th week after irradiation compared to patients with no radiation pneumonia (p<0.05). There was no significant difference in dosimetric parameters, including V5, V20, V30 and mean lung dose (MLD) and clinical factors, such as gender, age, smoking history, history of surgery and chemotherapy. CONCLUSION: The ratio of Th17/Treg cells may be an effective predictive factor of radiation pneumonia.	esophagus
Clinical Outcomes of Esophagojejunostomy in Totally Laparoscopic Total Gastrectomy: A Multicenter Study.	PURPOSE: To examine the short-term outcomes of intracorporeal anastomosis during totally laparoscopic total gastrectomy retrospectively at multiple institutions. PATIENTS AND METHODS: We collected data of the patients who had undergone totally laparoscopic total gastrectomy at 4 institutions. All patients received an intracorporeal esophagojejunostomy. RESULTS: Of the 215 patients evaluated, 147 underwent functional end-to-end anastomosis (FEEA) as the intracorporeal esophagojejunostomy (FEEA group), and 68 patients received a circular stapler anastomosis (Circular group). The rate of tumor invasion to the esophagus was significantly higher in the Circular group than in the FEEA group (33% vs. 6%, respectively; P<0.0001). Univariate and multivariate analyses revealed that the circular stapler anastomosis and high preoperative BMI were statistically significant risk factors for postoperative leakage. However, the rates of complications and mortality were not significantly different between groups. CONSIDERATION: Our results showed that each type of esophagojejunostomy is safe and feasible for patients with gastric cancer with acceptable morbidity and mortality.	esophagus
Can We Use Diet to Effectively Treat Esophageal Disease? A Review of the Current Literature.	PURPOSE OF REVIEW: Esophageal diseases represent a wide variety of conditions affecting esophageal anatomy, physiology, and motility. Therapy focuses on pharmacotherapy and endoscopic or surgical management. Dietary therapy can be considered in management algorithms for specific esophageal diseases. This review focuses on outlining the literature related to dietary therapy in gastroesophageal reflux disease, eosinophilic esophagitis, Barrett's esophagus, and esophageal adenocarcinoma. RECENT FINDINGS: Currently, data are strongest for dietary manipulation in eosinophilic esophagitis, specifically the six-food elimination diet. Dietary effects on gastroesophageal reflux disease are less clear, though newer research indicates that increased fiber with reduction in simple sugar intake may improve symptoms. In terms of Barrett's esophagus and esophageal adenocarcinoma, antioxidant intake may affect carcinogenesis, though to an unknown degree. Outcomes data regarding dietary manipulation for the management of esophageal diseases is heterogeneous. Given the rising interest in non-pharmacological treatment options for these patients, continued research is warranted.	esophagus
Disseminated tumour cells with highly aberrant genomes are linked to poor prognosis in operable oesophageal adenocarcinoma.	BACKGROUND: Chromosomal instability (CIN) has repeatedly been identified as a prognostic marker. Here we evaluated the percentage of aberrant genome per cell (PAG) as a measure of CIN in single disseminated tumour cells (DTC) isolated from patients with operable oesophageal adenocarcinoma (EAC), to assess the impact of CIN(high) DTCs on prognosis. METHODS: We isolated CK18(positive) DTCs from bone marrow (BM) or lymph node (LN) preparations of operable EAC patients. After whole-genome amplification, single DTCs were analysed for chromosomal gains and losses using metaphase-based comparative genomic hybridisation (mCGH). We calculated the PAG for each DTC and determined the critical threshold value that identifies high-risk patients by STEPP (Subpopulation Treatment Effect Pattern Plot) analysis in two independent EAC patient cohorts (cohort #1, n=44; cohort #2; n=29). RESULTS: The most common chromosomal alterations observed among the DTCs were typical for EAC, but the DTCs showed a varying PAG between individual patients. Generally, LNDTCs displayed a significantly higher PAG than BMDTCs. STEPP analysis revealed an increasing PAG of DTCs to be correlated with an increased risk for short survival in two independent EAC cohorts as well as in the corresponding pooled analysis. In all three data sets (cohort #1, cohort #2 and pooled cohort), PAG(high) DTCs conferred an independent risk for a significantly decreased survival. CONCLUSIONS: The analysis of PAG/CIN in solitary marker-positive DTCs identifies operable EAC patients with poor prognosis, indicating a more aggressive minimal residual disease.	esophagus
Microvessel density as a prognostic factor in esophageal squamous cell cancer patients: A meta-analysis.	BACKGROUND: To date, literature has emerged that shows contradictory results about the prognostic role of microvessel density (MVD) in esophageal squamous cell cancer (ESCC). The aim of the study set out to evaluate the correlation between MVD and the prognosis of ESCC. METHODS: Identified publications from various databases were obtained and reviewed. A meta-analysis was performed to evaluate the prognostic role of MVD among ESCC patients. RESULTS: A total of 11 eligible studies containing 891 ESCC cases were included in the meta-analysis. The pooled hazard ratio for overall survival was 2.39 (95% confidence interval 1.92-2.96, P < .001). Heterogeneity among the studies was not significant, and publication bias was not found. Subgroup analyses were also performed on different issues, such as districts, antibodies, and median age. CONCLUSION: High MVD is a prognostic factor among ESCC that indicated worse prognosis in these patients. More studies are needed, and through abundant evidence, the topic could be re-evaluated by then.	esophagus
