Sequential simulation (SqS) of clinical pathways: a tool for public and patient engagement in point-of-care diagnostics.	OBJECTIVES: Public and patient engagement (PPE) is fundamental to healthcare research. To facilitate effective engagement in novel point-of-care tests (POCTs), the test and downstream consequences of the result need to be considered. Sequential simulation (SqS) is a tool to represent patient journeys and the effects of intervention at each and subsequent stages. This case study presents a process evaluation of SqS as a tool for PPE in the development of a volatile organic compound-based breath test POCT for the diagnosis of oesophagogastric (OG) cancer. SETTING: Three 3-hour workshops in central London. PARTICIPANTS: 38 members of public attended a workshop, 26 (68%) had no prior experience of the OG cancer diagnostic pathway. INTERVENTIONS: Clinical pathway SqS was developed from a storyboard of a patient, played by an actor, noticing symptoms of oesophageal cancer and following a typical diagnostic pathway. The proposed breath testing strategy was then introduced and incorporated into a second SqS to demonstrate pathway impact. Facilitated group discussions followed each SqS. PRIMARY AND SECONDARY OUTCOME MEASURES: Evaluation was conducted through pre-event and postevent questionnaires, field notes and analysis of audiovisual recordings. RESULTS: 38 participants attended a workshop. All participants agreed they were able to contribute to discussions and like the idea of an OG cancer breath test. Five themes emerged related to the proposed new breath test including awareness of OG cancer, barriers to testing and diagnosis, design of new test device, new clinical pathway and placement of test device. 3 themes emerged related to the use of SqS: participatory engagement, simulation and empathetic engagement, and why participants attended. CONCLUSIONS: SqS facilitated a shared immersive experience for participants and researchers that led to the coconstruction of knowledge that will guide future research activities and be of value to stakeholders concerned with the invention and adoption of POCT.	esophagus
Giant oesophageal leiomyoma causing severe hypertension.	Leiomyoma is the most common oesophageal tumour and is symptomatic in about half of the patients. Dysphagia is the most common symptom. A 41-year-old woman presented with recent onset of severe orthostatic hypertension. During the cardiological work-up, a mediastinal mass was found at transthoracic echocardiogram. Further investigation (upper gastrointestinal endoscopy, endoscopic ultrasonography, CT scan and cardiac MRI) confirmed the diagnosis of a large oesophageal submucosal mass compressing the supradiaphragmatic inferior vena cava. The mass was resected through a minimally invasive right thoracoscopic approach with complete relief of symptoms and compression on the vena cava.	esophagus
Does neoadjuvant chemoradiotherapy increase survival in patients with resectable oesophageal cancer?	A best evidence topic in cardiothoracic surgery was written according to a structured protocol. The question addressed was whether trimodal therapy [neoadjuvant chemoradiotherapy (nCRT) in addition to surgery] improves survival in patients with resectable oesophageal cancer. Altogether 565 studies were identified using the below-mentioned search. Eleven represented the best evidence to answer the clinical question. The author, journal, date and country of publication, patient group, relevant outcomes and weaknesses are tabulated. All 11 studies were randomized controlled trials comparing surgery with trimodal therapy, 5 of which showed a survival advantage with combined treatment. The remaining six randomized controlled trials showed no difference between trimodal therapy and surgery alone. The 3-year survival for trimodal treatment varied between 19.3 and 58% compared with that for surgery alone which varied between 7 and 53%. Five of these studies compared trimodal therapy with surgery in terms of resection margins, three of which showed that trimodal therapy led to increased R0 resection rate. One study focused on the differences between adenocarcinoma and squamous cell tumours, and described equivalent effects of trimodal therapy in terms of survival. One randomized controlled trial showed improved survival in patients with complete regression of their tumour following induction treatment. Two studies suggested that induction treatment may lead to a higher operative mortality; however, an increase in disease-free survival was noted in one of the two studies. We conclude that trimodal therapy for resectable oesophageal cancer offers similar or even improved results compared with surgery alone in terms of survival. Furthermore, it is likely that there is an advantage for those patients who have a complete pathological response following induction treatment.	esophagus
Survival After Surgical Resection of Stage IV Esophageal Cancer.	BACKGROUND: Five-year survival of stage IV esophageal cancer is rare. The treatment of advanced esophageal cancer is typically palliative and the role of surgery remains controversial. We sought to understand the impact of curative surgery on survival and identify any favorable tumor or patient characteristics that might make surgical resection appropriate when treating stage IV esophageal cancer. METHODS: A retrospective review of 3,500 esophagectomies performed at our institution from 1985 to 2013 identified 52 (1.5%) patients with stage IV esophageal cancer who underwent surgical resection with intent for cure. In 46 (88.5%) patients, M1 disease was discovered at the time of surgery and 6 (11.5%) patients had known M1 disease prior to surgery. RESULTS: Median age at the time of surgery was 60 years (range, 31 to 81 years). The majority of patients were men (82.7%) with adenocarcinoma (88.5%). Neoadjuvant therapy was used in 18 (34.6%) patients; all patients operated on after 1999 received neoadjuvant therapy. An Ivor Lewis esophagectomy was performed in 39 (75%) patients. Follow-up was complete in all patients for a median of 324 days (range, 4 days to 8.5 years). Overall, 1-year survival was 29% and 5-year survival was 6%. There was no significant difference in survival between patients with known preoperative versus intraoperative discovery of M1 disease. Factors associated with improved survival included neoadjuvant treatment, low T stage, and lack of alcohol use. CONCLUSIONS: Few patients with stage IV esophageal cancer survive long term after surgical resection, though 5-year survival can occur. Our current recommendation is that esophagectomy should not be performed for stage IV disease.	esophagus
Perioperative chemotherapy with FOLFOX in resectable gastroesophageal adenocarcinoma in real life practice: An AGEO multicenter retrospective study.	PURPOSE: Perioperative chemotherapy with 5-fluorouracil and cisplatin, with or without epirubicin, improves overall survival in resectable gastroesophageal junction and gastric adenocarcinoma. The aim of this retrospective multicenter study was to evaluate the safety and efficacy of perioperative chemotherapy with a FOLFOX-based regimen. PATIENTS AND METHODS: We enrolled patients with resectable gastric or gastroesophageal adenocarcinoma, who had at least 3 cycles of a pre-operative FOLFOX-based regimen. The primary end point was the feasibility of the peri-operative chemotherapy. RESULTS: We enrolled 109 patients from 2007 to 2012 in 12 centres. Their median age was 66, 67% were men and 73% had gastric tumours. The median number of chemotherapy courses was 6 with a median of 4 pre-operative cycles and 2 post-operative cycles. Twenty-three patients received at least 8 cycles of chemotherapy. In univariate analysis, the Karnofsky index at inclusion was the only factor associated with 8 cycles of chemotherapy. An R0 resection was achieved in 100 patients (95.2%). CONCLUSION: The FOLFOX-based perioperative regimen achieves favourable results in real life practice. The optimal number of chemotherapy cycle remains to be determined. FOLFOX regimen may be used as an alternative treatment option to a cisplatin-based regimen in resectable gastroesophageal adenocarcinoma. A prospective randomized trial is needed to confirm these results.	esophagus
Inhibition of miR-196a affects esophageal cancer cell growth in vitro.	Esophageal cancer (EC) is one of the most common causes of cancer-related mortality worldwide. Several oncogenes such as miR-196a have been implicated in the carcinogenesis and progression of EC. The purpose of this study was to determine the effects of anti-miR-196a on the growth and survival of human EC cells in vitro. We found that miR-196a was highly expressed in both TE1 and EC109 cells and that miR-196a knockdown inhibited cell proliferation and migration. Furthermore, miR-196a knockdown sensitized EC cells to radiation treatment and chemotherapy. Inhibition of miR-196a also altered cell cycle progression and induced G(2)/M arrest, which was related to changes in the levels of cyclin B1. ABCG2, which was highly expressed in untransfected EC cells, was inhibited by miR-196a knockdown. Thus, our results confirm the fact that miR-196a is highly involved in the biological behavior of EC progression in vitro. We conclude that miR-196a is a useful biological marker and potential therapeutic target for the clinical treatment of human EC.	esophagus
Esophageal Adenocarcinoma: Screening, Surveillance, and Management.	Esophageal adenocarcinoma (EAC) is a growing problem with a rapidly rising incidence. Risk factors include gastroesophageal reflux disease, central obesity, and smoking. The prognosis of EAC remains poor because it is usually diagnosed late, and many efforts have been made to improve prevention, early detection, and treatment. Acid suppression, nonsteroidal antiinflammatory drugs (NSAIDs), and statins may play a role in chemoprevention. Screening for Barrett's esophagus (BE), the only known precursor lesion of EAC, is indicated for individuals with increased risk. Endoscopic surveillance of patients with BE likely improves overall outcomes. Endoscopic ablation and resection is highly effective for treating dysplastic BE and early EAC, whereas esophagectomy is indicated for patients with locally advanced disease. This review covers epidemiology, staging, screening, and prevention of EAC as well as endoscopic and surgical management.	esophagus
Prognostic Significant or Not? The Positive Circumferential Resection Margin in Esophageal Cancer: Impact on Local Recurrence and Overall Survival in Patients Without Neoadjuvant Treatment.	OBJECTIVE: The aim of this study is to investigate the impact of the circumferential resection margin (CRM) in esophageal cancer on survival and recurrence in patients without pretreatment. BACKGROUND: Whereas the infiltration of the proximal or distal resection margin is associated with poor survival and higher recurrence, studies looking at the role of the circumferential resection margin on survival and local recurrence after esophagectomy are conflicting. METHODS: Influence of CRM infiltration according to the College of American Pathologists (CAP) and Royal College of Pathologists (RCP) on long-term survival of 180 patients with resected pT3 tumors and without neoadjuvant therapy was analyzed. RESULTS: A positive CRM was found in 76 (42.4%) patients according to RCP and 44 (24.4%) patients according to CAP. The CRM status had neither according to CAP nor according to RCP a significant impact on overall survival (P = 0.317 and 0.655, respectively), local recurrence (P = 0.716 and 0.900, respectively), or distant tumor relapse (P = 0.303 and 0.471, respectively).Lymphatic tumor spread found in 129 (71.7%) patients was an independent prognosticator (P = 0.002). In 137 (76.1%) patients who had a transthoracic esophagectomy a CRM infiltration was significantly lower according to CAP compared with 43 (23.9%) patients who had a transhiatal esophagectomy (P = 0.026). CONCLUSIONS: CRM was found to have no impact on survival and recurrence in esophageal cancer. Therefore, the possible impact of neoadjuvant pretreatment in locally advanced tumors should be considered with caution in terms of an improved resectability.	esophagus
Epidemiology of Barrett's esophagus and esophageal adenocarcinoma in Spain. A unicentric study.	INTRODUCTION: Barrett's esophagus (BE) is an acquired disease defined by the presence of intestinal metaplasia with goblet cells in the distal esophagus. The prevalence of BE has increased dramatically over the last years. AIMS: The primary aims of the study were to analyze the characteristics of BE and esophageal adenocarcinoma (EAC) in a Spanish health district during a follow-up period. METHODOLOGY: Sociodemographic factors, alcohol consumption and cigarette smoking were analyzed. We also studied the histological behavior and cause of death in each group. RESULTS: In the present study 430 patients were included, 338 with BE and 92 with EAC. Incidence rates have risen from 2.25 and 1.25 per 100,000 inhabitants in 1996 to 6.5 and 4.75 per 100,000 in 2011, respectively. In the EAC group, male gender, age and alcohol consumption were higher in comparison to the BE group, and the overall survival was 23 months. In the BE group, the main causes of death were non-esophageal cancer and cardiovascular disease. CONCLUSIONS: The incidence and prevalence rates of AEC and BE have risen over the past years. Risk factors for these conditions were male gender, age and alcohol consumption. Long BE (> 3 cm) is involved in dysplasia progression. AEC diagnosis mainly occurs after neoplasia is detected and, in a few cases, due to a previous BE. Cardiovascular diseases and non-esophageal cancers have been found to be the main cause of death in BE patients.	esophagus
Texture analysis of (18)F-FDG PET/CT to predict tumour response and prognosis of patients with esophageal cancer treated by chemoradiotherapy.	PURPOSE: This retrospective study was done to examine whether the heterogeneity in primary tumour F-18-fluorodeoxyglucose ((18)F-FDG) distribution can predict tumour response and prognosis of patients with esophageal cancer treated by chemoradiotherapy (CRT). METHODS: The enrolled 52 patients with esophageal cancer underwent (18)F-FDG-PET/CT studies before CRT. SUVmax, SUVmean, metabolic tumour volume (MTV, SUV ≥ 2.5), total lesion glycolysis (TLG) and six heterogeneity parameters assessed by texture analysis were obtained. Patients were classified as responders or non-responders according to Response Evaluation Criteria in Solid Tumors. Progression-free survival (PFS) and overall survival (OS) were calculated by the Kaplan-Meier method. Prognostic significance was assessed by Cox proportional hazards analysis. RESULTS: Thirty four non-responders showed significantly higher MTV (p = 0.006), TLG (p = 0.007), intensity variability (IV; p = 0.003) and size-zone variability (SZV; p = 0.004) than 18 responders. The positive and negative predictive values for non-responders were 77 % and 69 % in MTV, 76 % and 100 % in TLG, 78 % and 67 % in IV and 78 % and 82 % in SZV, respectively. Although PFS and OS were significantly shorter in patients with high MTV (PFS, p = 0.018; OS, p = 0.014), TLG (PFS, p = 0.009; OS, p = 0.025), IV (PFS, p = 0.013; OS, p = 0.007) and SZV (PFS, p = 0.010; OS, p = 0.007) at univariate analysis, none of them was an independent factor, while lymph node status, stage and tumour response status were independent factors at multivariate analysis. CONCLUSION: Texture features IV and SZV, and volumetric parameters MTV and TLG can predict tumour response, but all of them have limited value in prediction of prognosis of patients with esophageal cancer treated by CRT.	esophagus
Genotype Distribution of Human Papillomavirus among Women with Cervical Cytological Abnormalities or Invasive Squamous Cell Carcinoma in a High-Incidence Area of Esophageal Carcinoma in China.	Data of HPV genotype including 16 high-risk HPV (HR-HPV) and 4 low-risk HPV from 38,397 women with normal cytology, 1341 women with cervical cytology abnormalities, and 223 women with ISCC were retrospectively evaluated by a hospital-based study. The prevalence of high-risk HPV (HR-HPV) was 6.51%, 41.83%, and 96.86% in women with normal cytology, cervical cytology abnormalities, and ISCC, respectively. The three most common HPV types were HPV-52 (1.76%), HPV-16 (1.28%), and HPV-58 (0.97%) in women with normal cytology, whereas the most prevalent HPV type was HPV-16 (16.85%), followed by HPV-52 (9.55%) and HPV-58 (7.83%) in women with cervical cytology abnormalities. Specifically, HPV-16 had the highest frequency in ASC-H (24.16%, 36/149) and HSIL (35.71%, 110/308), while HPV-52 was the most common type in ASC-US (8.28%, 53/640) and LSIL (16.80%, 41/244). HPV-16 (75.78%), HPV18 (10.31%), and HPV58 (9.87%) were the most common types in women with ISCC. These data might contribute to increasing the knowledge of HPV epidemiology and providing the guide for vaccine selection for women in Shantou.	esophagus
Proton therapy posterior beam approach with pencil beam scanning for esophageal cancer : Clinical outcome, dosimetry, and feasibility.	PURPOSE: The aim of this study is to present the dosimetry, feasibility, and preliminary clinical results of a novel pencil beam scanning (PBS) posterior beam technique of proton treatment for esophageal cancer in the setting of trimodality therapy. METHODS: From February 2014 to June 2015, 13 patients with locally advanced esophageal cancer (T3-4N0-2M0; 11 adenocarcinoma, 2 squamous cell carcinoma) were treated with trimodality therapy (neoadjuvant chemoradiation followed by esophagectomy). Eight patients were treated with uniform scanning (US) and 5 patients were treated with a single posterior-anterior (PA) beam PBS technique with volumetric rescanning for motion mitigation. Comparison planning with PBS was performed using three plans: AP/PA beam arrangement; PA plus left posterior oblique (LPO) beams, and a single PA beam. Patient outcomes, including pathologic response and toxicity, were evaluated. RESULTS: All 13 patients completed chemoradiation to 50.4 Gy (relative biological effectiveness, RBE) and 12 patients underwent surgery. All 12 surgical patients had an R0 resection and pathologic complete response was seen in 25 %. Compared with AP/PA plans, PA plans have a lower mean heart (14.10 vs. 24.49 Gy, P < 0.01), mean stomach (22.95 vs. 31.33 Gy, P = 0.038), and mean liver dose (3.79 vs. 5.75 Gy, P = 0.004). Compared to the PA/LPO plan, the PA plan reduced the lung dose: mean lung dose (4.96 vs. 7.15 Gy, P = 0.020) and percentage volume of lung receiving 20 Gy (V(20); 10 vs. 17 %, P < 0.01). CONCLUSION: Proton therapy with a single PA beam PBS technique for preoperative treatment of esophageal cancer appears safe and feasible.	esophagus
Downregulation of p70S6K Enhances Cell Sensitivity to Rapamycin in Esophageal Squamous Cell Carcinoma.	It has been demonstrated that mTOR/p70S6K pathway was abnormally activated in many cancers and rapamycin and its analogs can restrain tumor growth through inhibiting this pathway, but some tumors including esophageal squamous cell carcinoma (ESCC) appear to be insensitive to rapamycin in recent studies. In the present study, we explored the measures to improve the sensitivity of ESCC cells to rapamycin and identified the clinical significance of the expression of phosphorylated p70S6K (p-p70S6K). The results showed that, after downregulating the expression of p70S6K and p-p70S6K by p70S6K siRNA, the inhibitory effects of rapamycin on cell proliferation, cell cycle, and tumor growth were significantly enhanced in vitro and in vivo. Furthermore, p-p70S6K had strong positive expression in ESCC tissues and its expression was closely related to lymph node metastasis and the TNM staging. These results indicated that p-p70S6K may participate in the invasion and metastasis in the development of ESCC and downregulation of the expression of p-p70S6K could improve the sensitivity of cells to rapamycin in ESCC.	esophagus
Impact of the radiotherapy combined with cisplatin plus paclitaxel chemotherapy on the immunologic functions in the patients with esophageal cancer.	To study the impact of radiotherapy combined with cisplatin plus paclitaxel chemotherapy on the immunologic functions in the patients with esophageal cancer, from July 2012 to September 2014, 82 patients of esophageal cancer which were receiving treatment in our hospital chose out for this research. Among them, 42 patients received radiotherapy only, as the control group; while the other 40 patients with concurrent cisplatin plus paclitaxel chemo radiotherapy was taken as the observation group. Then the immunologic functions, toxic and side effects were compared between the two groups as well as the survival rates after 3-year-followup-visit, Th level of the total T cells, Th cells and the ratio of Th cells to Ts cells after receiving treatment all increased significantly compared with prior treatment. And the difference was statistically significant (P<0.05). After the treatment, the level of T cells, Th cells and the ratio of Th cells to Ts cells of the observation group were all significantly lower than the control group, and the difference was statistically significant (P<0.05). While the difference of the ratio of Ts cells to natural killer cells (NK cells) between the two groups were not significant. The toxic and side effects were mainly myelosuppression, decrease leukocyte, esophagit, nausea and vomiting, and it was not statistically significant in the difference between the two groups (P >0.05), the survival rates from the first year to the third year in the observation group were respectively significantly higher than the control group, and the difference was statistically significant (P<0.05). Radiotherapy combined with cisplatin plus paclitaxel chemotherapy could properly increase the immunologic functions in patients with esophageal cancer, benefiting for the survival rate with a good security. Therefore, it was worth promoting.	esophagus
[Vital Sign Changes and the Requirement of Analgesics after Discontinuation of Dexmedetomidine in Patients after Esophageal Cancer Surgery.].	BACKGROUND: There is few study to examine the vital sign changes and the requirement of analgesics after discontinuation of dexmedetomidine in postopera- tive patients. METHODS: This is a retrospective observational study conducted in 74 patients after esophageal cancer sur- gery. We recorded vital signs including blood pressure, heart rate and respiratory rate one hour before discon- tinuation of dexmedetomidine, and at 1, 2, 4, 6 hours after its discontinuation. We also recorded the use of opioid and analgesic within 6 hours after discontinua- tion. RESULTS: Mean blood pressure, pulse rate, and respi- ratory rate significantly increased after DEX discon- tinuation. Compared with the data before discontinua- tion, the mean blood pressure increased by 13.3 mmHg, heart rate increased by 7.5 beats - min- and respira- tory rate increased by 3.0 times - min-' in average at 6 hours after discontinuation. There were 28 patients (38%) who required the additional analgesics within 6 hours after discontinuation. CONCLUSIONS: After discontinuation of dexmedetomi- dine, significant changes of vital signs, especially in mean blood pressure, were observed in post-esopha- gectomy patients. About 38% of them required addi- tional analgesics within 6 hours after dexmedetomidine discontinuation.	esophagus
