    Despite advances in our knowledge of esophageal cancer, 50% of patients present with incurable disease, and the overall survival after diagnosis is poor. The incidence of esophageal adenocarcinoma of the distal esophagus is rising at a rapid rate in developed countries. Recent advances in the epidemiology of esophageal cancer offer insights into preventive strategies in patients who are at risk. New developments in diagnosis may help detect the disease at an early stage. New diagnostic modalities permit more accurate staging procedures and allow appropriate selection of therapy. New studies provide more information on multimodality therapy for esophageal cancer, and new endoscopic techniques allow resection of small lesions without surgery. New stent designs provide better palliation by providing tumor ingrowth. These developments in the treatment of esophageal cancer are the focus of this review.

    Full Text Available Purpose: Dysphagia is a common initial presentation in locally advanced esophageal cancer and negatively impacts patient quality of life and treatment compliance. To induce fast relief of dysphagia in patients with potentially operable esophageal cancer high-dose-rate (HDR brachytherapy was applied prior to definitive radiochemotherapy. Material and methods : In this single arm phase II clinical trial between 2013 to 2014 twenty patients with locally advanced esophageal cancer (17 squamous cell and 3 adenocarcinoma were treated with upfront 10 Gy HDR brachytherapy, followed by 50.4 Gy external beam radiotherapy (EBRT and concurrent chemotherapy with cisplatin/5-fluorouracil. Results : Tumor response, as measured by endoscopy and/or computed tomography scan, revealed complete remission in 16 and partial response in 4 patients (overall response rate 100%. Improvement of dysphagia was induced by brachytherapy within a few days and maintained up to the end of treatment in 80% of patients. No differences in either response rate or dysphagia resolution were found between squamous cell and adenocarcinoma histology. The grade 2 and 3 acute pancytopenia or bicytopenia reported in 4 patients, while sub-acute adverse effects with painful ulceration was seen in five patients, occurring after a median of 2 months. A perforation developed in one patient during the procedure of brachytherapy that resolved successfully with immediate surgery. Conclusions : Brachytherapy before EBRT was a safe and effective procedure to induce rapid and durable relief from dysphagia, especially when combined with EBRT.

    Cancer of the esophagus is an underestimated, poorly understood, and changing disease. Its overall 5-year survival is less than 20%, even in the United States, which is largely a function of a delay in diagnosis until its more advanced stages. Additionally, the epidemiologic complexities of esophageal cancer are vast, rendering screening and prevention limited at best. First, the prevalence of esophageal cancer is unevenly distributed throughout the world. Second, the two histological forms (squamous cell and adenocarcinoma) vary in terms of their geographic prevalence and associated risk factors. Third, some populations appear at particular risk for esophageal cancer. And fourth, the incidence of esophageal cancer is in continuous flux among groups. Despite the varied prevalence and risks among populations, some factors have emerged as consistent associations while others are only now becoming more fully recognized. The most prominent, scientifically supported, and long-regarded risk factors for esophageal cancer are tobacco, alcohol, and reflux esophagitis. Inasmuch as the above are regarded as important risk factors for esophageal cancer, they are not the sole contributors. Dietary habits, nutrition, local customs, and the environment may be contributory. Along these lines, vitamins, minerals, fruits, vegetables, meats, fats, salted foods, nitrogen compounds, carcinogens, mycotoxins, and even the temperature of what we consume are increasingly regarded as potential etiologies for this deadly although potentially preventable disease. The goal of this review is to shed light on the less known role of nutrition and dietary habits in esophageal cancer.

  13. Esophageal Cancer Risk Prediction Models

    Developing statistical models that estimate the probability of developing esophageal cancer over a defined period of time will help clinicians identify individuals at higher risk of specific cancers, allowing for earlier or more frequent screening and counseling of behavioral changes to decrease risk.

    Full Text Available Background. Eosinophilic esophagitis is an inflammatory condition where there is a dense infiltration of eosinophils typically exceeding fifteen cells per high power field. Familial Mediterranean fever is an autosomal recessive disorder characterized by brief, acute, and self-limited episodes of fever and polyserositis that recur at irregular intervals. Case Presentation. A three-year-and-nine-month-old Iranian girl was admitted to our center. The patient’s parents complained of a history of abdominal pain, poor appetite, and poor weight gain from 1.5 years ago and episodes of food impaction after starting solid foods. Eosinophilic esophagitis was diagnosed based on histology. Because of continuing abdominal pain after treatment of eosinophilic esophagitis, the episodic nature of disease, and the presence of fever with pain, screening for familial Mediterranean fever mutation was performed and the patient was found to be heterozygote for Mediterranean fever. Conclusion. We have reported a case of eosinophilic esophagitis coexisting with familial Mediterranean fever which has not been described previously.

    Full Text Available The incidence of esophageal cancer is rapidly increasing especially in developing countries. The major risk factors include unhealthy lifestyle practices such as alcohol consumption, smoking, and chewing tobacco to name a few. Diagnosis at an advanced stage and poor prognosis make esophageal cancer one of the most lethal diseases. These factors have urged further research in understanding the pathophysiology of the disease. Animal models not only aid in understanding the molecular pathogenesis of esophageal cancer but also help in developing therapeutic interventions for the disease. This review throws light on the various recent laboratory animal models for esophageal cancer.

    There have been many new developments in our understanding of esophageal carcinoma biology over the past several years. Information regarding both of the major forms of this disease, adenocarcinoma and squamous cell carcinoma, has accumulated in conjunction with data on precursor conditions such as Barrett's esophagus. Interesting and promising findings have included overexpression of proto-oncogenes,loss of heterozygosity at multiple chromosomal loci, tumor suppressor gene inactivation, epigenetic silencing by DNA methylation, and mutations and deletions involving the tumor suppressor gene p53. Important cancer pathways, the cyclin kinase inhibitor cascade and the DNA mismatch repair process, implicated in the genesis of multiple tumor types have also been inculpated in esophageal carcinogenesis. Alterations in the p16 and p15 cyclin kinase inhibitors including point mutations and homozygous deletions have been reported in primary esophageal tumors. Further developments in the field of molecular carcinogenesis of esophageal malignancies promise to yield improvements in prevention, early detection, prognostic categorization, and perhaps gene-based therapy of this deadly disease.

    Full Text Available Sarah Baker, Alysa Fairchild Department of Radiation Oncology, Cross Cancer Institute, University of Alberta, Edmonton, AB, Canada Abstract: Radiation-induced esophagitis is the most common local acute toxicity of radiotherapy (RT delivered for the curative or palliative intent treatment of lung cancer. Although concurrent chemotherapy and higher RT dose are associated with increased esophagitis risk, advancements in RT techniques as well as adherence to esophageal dosimetric constraints may reduce the incidence and severity. Mild acute esophagitis symptoms are generally self-limited, and supportive management options include analgesics, acid suppression, diet modification, treatment for candidiasis, and maintenance of adequate nutrition. Esophageal stricture is the most common late sequela from esophageal irradiation and can be addressed with endoscopic dilatation. Approaches to prevent or mitigate these toxicities are also discussed. Keywords: non–small cell lung cancer, acute, late, toxicity, stricture

    Introduction Doxycycline-induced esophageal ulcer patients are mostly young persons with no history of esophageal dysfunction. Heartburn, midsternal pain and dysphagia are the most common symptoms. It has generally a benign course. The present case is the first report of doxycycline-induced extensive ulcerations, mimicking esophageal cancer in two esophageal segments alongside, in the literature. Case presentation This report describes a 16-year-old Caucasian girl who, while taking doxycycline capsules100 mg twice a day for acne vulgaris for 3 months, developed these symptoms. An upper endoscopy revealed multiple circumferential deep ulcerations surrounding fragile, irregular, hyperemic and hypertrophic mucosa at the level of the mid-esophagus and concomitantly in the lower esophageal sphincter. The lesions were biopsied to exclude esophageal carcinoma because of the suspicious appearance in the endoscopic examination. The histopathological examination, haematoxylin and eosin stained sections showed ulceration with a mixed inflammatory infiltrate. Doxycycline was discontinued and she was given sucralfate 1 g qid and omeprazole 20 mg bid orally. All symptoms of the patient were resolved on the third day of the treatment. After 4 weeks of the therapy, an upper endoscopic control examination demonstrated normal findings. Conclusion The present case has been an uncommon presentation of doxycycline-induced extensive ulcerations, mimicking esophageal cancer in two esophageal segments, concomitantly. Even the lesions were biopsied to exclude esophageal carcinoma. A modification on the behavior of taking drugs can prevent these unpleasant complications. PMID:18778470

    Esophageal and gastric cancers are both common and deadly. Patients present most often after disease progression and survival is therefore poor. Due to demographic variability and recent changes in disease incidence, much emphasis has been placed on studying risk factors for both esophageal and gastric cancers.However, with increasing understanding of these diseases, low survival rates persist and continued intensive studies are necessary to optimize treatment plans. This review article discusses updates in the evolving epidemiology, clinical presentation, risk factors,and diagnostic and treatment modalities of esophageal and gastric cancers.

    Because the conflicting data currently available from the performed randomized trials it is very difficult to provide strict guidelines for the treatment of patients with locoregional advanced esophageal cancers. Surgery however, remains the standard of care for potentially resectable disease. Preoperative chemotherapy is still controversial with two large randomized trials resulting in two different conclusions regarding the survival benefit. Preoperative chemoradiation is also controversial since only one randomized trial showed a clear survival benefit however, the patients treated with surgery alone in this trial had an unusually poor outcome. And the study by Urba et al was not powered enough to show a clear survival benefit for patients treated with neoadjuvant chemoradiation. The results of three metaanalysis of these randomized studies show lower rate of resection, higher rate of R0-resection, more often postoperative mortality and better prognosis for patients with neoadjuvant radiochemotherapy. As a consequence one may consider offering neoadjuvant chemotherapy or neoadjuvant radiochemotherapy to patients with locallyadvanced disease under the premise that patients have a good performance status and understand the controversies about this therapeutic option. Larger trials with sufficient power to clearly detect survival benefits for patients treated with neoadjuvant chemotherapy or radiochemotherapy are necessary before this therapeutic option will be the standard of care.

    Patients with esophageal cancer have a poor prognosis because they often have no symptoms until their disease is advanced.There are no screening recommendations for patients unless they have Barrett's esophagitis or a significant family history of this disease.Often,esophageal cancer is not diagnosed until patients present with dysphagia,odynophagia,anemia or weight loss.When symptoms occur,the stage is often stage Ⅲ or greater.Treatment of patients with very early stage disease is fairly straight forward using only local treatment with surgical resection or endoscopic mucosal resection.The treatment of patients who have locally advanced esophageal cancer is more complex and controversial.Despite multiple trials,treatment recommendations are still unclear due to conflicting data.Sadly,much of our data is difficult to interpret due to many of the trials done have included very heterogeneous groups of patients both histologically as well as anatomically.Additionally,studies have been underpowered or stopped early due to poor accrual.In the United States,concurrent chemoradiotherapy prior to surgical resection has been accepted by many as standard of care in the locally advanced patient.Patients who have metastatic disease are treated palliatively.The aim of this article is to describe the multidisciplinary approach used by an established team at a single high volume center for esophageal cancer,and to review the literature which guides our treatment recommendations.

    2008-10-01

    Esophageal cancer represents a major public health problem worldwide. Several minimally invasive esophagectomy (MIE) techniques have been described and represent a safe alternative for the surgical management of esophageal cancer in selected centers with high volume and expertise in them. This article reviews the most recent and largest series evaluating MIE techniques. Recent larger series have shown MIE to be equivalent in postoperative morbidity and mortality rates to conventional surgery. MIE has been associated with less blood loss, less postoperative pain, and decreased intensive care unit and hospital length of stay compared with conventional surgery. Despite limited data, conventional surgery and MIE have shown no significant difference in survival, stage for stage. The myriad of MIE techniques complicates the debate of defining the optimal surgical approach for treating esophageal cancer. Randomized controlled trials comparing MIE with conventional open esophagectomy are needed to clarify the ideal procedure with the lowest postoperative morbidity, best quality of life after surgery, and long-term survival.

    Full Text Available Esophageal cancer is the second and third most common malignancy in Iranian malesand females, respectively, claiming lives of approximately 5800 Iranians each year.Squamous cell carcinoma (SCC is presently the most common type accounting forabout 90% of all esophageal cancers in Iran. Recent studies have shown that there isa gradual increase in the incidence of adenocarcinoma of the distal esophagus alongwith gastric cardia adenocarcinoma. Thirty-five years ago, the age standardizied rate (ASR of esophageal SCC in thecity of Gonbad (Golestan Province, northeast of Iran was found to be one of the highestrates for any single cancer that had been reported worldwide (ASR >100/105/year.Recent studies have shown that the incidence of SCC in Gonbad has declined to lessthan half of what it was in the past. This decline in the incidence of esophageal SCCparallels an improvement in the socioeconomic situation of people living in thisregion. According to recent cancer registry data in Iran there is still an obviousintracountry variability between the incidence of esophageal cancer in the south withan ASR of 3 for males and 2 for females in Kerman and 43 and 36 in the northeasternprovince of Golestan. The reasons for this very high rate of SCC in northeastern Iranhave been the subject of several studies during the past 35 years. According to resultsof these studies the suspected risk factors are: low intake of fruits and vegetables, drinkinghot tea, consumption of opium products and tobacco, H.pyloriinfection in the stomach,using unhealthy drinking water from cisterns and genetic susceptibility.

The total dose via EBRT was 50-60 Gy, which was delivered over a period of 5 to 6 weeks with normal fractionation. Results : The median survival time for the 191 patients was 23.6 months, and the 5-year rates for overall survival (OS and local-regional control (LRC were 28.7% and 54.2%, respectively. The patients’ age was a factor that was significantly associated with OS (p = 0.010, according to univariate analysis. The 5-year OS (LRC was 37.3% (58.6% for patients aged 70-74 years and 14.5% (47.9% for patients aged > 74 years (p = 0.010 and p = 0.038. In multivariate analysis, age and clinical N stage were associated with OS and LRC (p = 0.011 [0.041] and p = 0.005 [0.005]. From the time of treatment completion to the development of local-regional recurrence or death, 5 (2.6% patients experienced fistula and 15 (7.9% experienced massive bleeding. The incidence of severe late complications was related to older age (p = 0.027, higher NBT dose/fraction (20-25 Gy/5 fractions, and higher total dose (> 66 Gy. Conclusions : The clinical data indicated that NBT in combination with EBRT produced favorable local control and long-term survival rates for elderly patients with ESCC, and that the side effects were tolerable. Patient’s age, clinical stage N status, and radiation dose could be used to select the appropriate treatment for elderly patients.

    AIM To understand the molecular mechanism of esophageal cancer development and provide molecular markers for screening high-risk populations and early diagnosis. METHODS Two-dimensional electrophoresis combined with mass spectrometry were adopted to screen differentially expressed proteins in nine cases of fetal esophageal epithelium, eight cases of esophageal cancer, and eight cases of tumor-adjacent normal esophageal epithelium collected from fetuses of different gestational age, or esophageal cancer patients from a high-risk area of esophageal cancer in China. Immunohistochemistry (avidin-biotin-horseradish peroxidase complex method) was used to detect the expression of peroxiredoxin (PRX)6 in 91 cases of esophageal cancer, tumor-adjacent normal esophageal tissue, basal cell hyperplasia, dysplasia, and carcinoma in situ, as well as 65 cases of esophageal epithelium from fetuses at a gestational age of 3-9 mo. RESULTS After peptide mass fingerprint analysis and search of protein databases, 21 differential proteins were identified; some of which represent a protein isoform. Varying degrees of expression of PRX6 protein, which was localized mainly in the cytoplasm, were detected in adult and fetal normal esophageal tissues, precancerous lesions, and esophageal cancer. With the progression of esophageal lesions, PRX6 protein expression showed a declining trend (P PRX6 protein expression showed a declining trend with age (P PRX6 protein expression was significantly higher in well-differentiated esophageal cancer tissues than in poorly differentiated esophageal cancer tissues (P PRX6 protein is associated with fetal esophageal development and cancer differentiation.

    Full Text Available BACKGROUND: To estimate the contribution of tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake to esophageal cancer mortality and incidence in China. METHODOLOGY/PRINCIPAL FINDINGS: We calculated the proportion of esophageal cancer attributable to four known modifiable risk factors [population attributable fraction (PAF]. Exposure data was taken from meta-analyses and large-scale national surveys of representative samples of the Chinese population. Data on relative risks were also from meta-analyses and large-scale prospective studies. Esophageal cancer mortality and incidence came from the 3(rd national death cause survey and population-based cancer registries in China. We estimated that 87,065 esophageal cancer deaths (men 67,686; women: 19,379 and 108,206 cases (men: 83,968, women: 24,238 were attributable to tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake in China in 2005. About 17.9% of esophageal cancer deaths among men and 1.9% among women were attributable to tobacco smoking. About 15.2% of esophageal cancer deaths in men and 1.3% in women were caused by alcohol drinking. Low vegetable intake was responsible for 4.3% esophageal cancer deaths in men and 4.1% in women. The fraction of esophageal cancer deaths attributable to low fruit intake was 27.1% in men and 28.0% in women. Overall, 46% of esophageal cancers (51% in men and 33% in women were attributable to these four modifiable risk factors. CONCLUSIONS/SIGNIFICANCE: Tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake were responsible for 46% of esophageal cancer mortality and incidence in China in 2005. These findings provide useful data for developing guidelines for esophageal cancer prevention and control in China.

    Incidence data retrieved from population-based cancer registration were used to analyze the esophageal cancer incidence and trend in China. The results can provide basic information for prevention and control of esophageal cancer. Esophageal cancer incidence data in 2012 were retrieved from the National Central Cancer Registry, nationwide new esophageal cancer cases were estimated using age-specific rate by urban or rural and gender and national population in 2012. Esophageal cancer incidence data from 22 cancer registries were used to analyze the trend during 2000-2011. The estimates of new cases of esophageal cancer were about 286.7 thousand in 2012 in China. The incidence rate was 21.17/10(5,) the age-standardized incidence rates by Chinese standard population and by world population were 14.73/10(5) and 14.93/10(5,) respectively, and the cumulative incidence rate was 1.91%.There was a decreasing trend of incidence rate of esophageal cancer in registration areas of China during 2000-2011 with an average annual percentage change (AAPC) of 0.9% (95%CI: -1.6% to -0.1%), no significant differences were observed in urban area and an increasing trend with AAPC of 1.3% (95%CI: 0.2% to 2.5%) in rural area. After age standardization, the incidence rate was significantly decreased, with AAPC of -4.0% (95%CI: -5.5% to -2.6%) overall, -3.8% (95%CI: -4.9% to -2.7%) in urban and -1.7% (95%CI: -3.0% to -0.4%) in rural areas. Esophageal cancer is one of the most common cancers in China and is an emphasis for cancer control. After effective control of risk factors and development of esophageal cancer screening techniques in high-risk areas for years, esophageal cancer incidence appears to have a significant decreasing trend.

    This paper reports on an autopsied case manifesting an esophageal cancer that had developed 13 years after radiotherapy for lung cancer. The patient was a 61-year-old man. He was found to have a squamous cell carcinoma of the right lower bronchus with a swelling of the mediastinal and left supraclavicular lymph nodes in July of 1973. He received 60 Gy of irradiation in the right lung, the mediastinum, and the left supraclavicular region. Later, after doing well until August of 1986, a squamous cell carcinoma of the esophagus was found at the upper intrathoracic site. Thus, he also received additional radiotherapy but died of pneumonia after this local recurrence 7 months later. At autopsy, no local recurrence of the primary lung cancer was found. The site of esophageal cancer was far from that of the primary lung cancer thought it was included in the previous treatment ports. This suggests the possibility that the primary esophageal cancer had been induded by therapeutic irradiation. So far as we know, this is the first report of esophageal cancer that may have developed after irradiation for lung cancer.

    Thoracoscopic approaches for esophageal cancer are still disparate. Complete scopic technique is feasible for esophagectomy. Mini-thoracotomy is effective for excellent exposure of the mediastinum for lymph node dissection. The magnifying effect of a video, by keeping the camera in close proximity to the dissection is essential to perform the same quality of dissection as open surgery. The benefit, for respiratory morbidity, remains to be studied in a large number of patients. Minimizing the chest wall injury contributed, to the reduction of constrictive pulmonary damage. Survival after the thoracoscopic approach was favorably compared with open surgery, when extensive lymphadenectomy was performed. Because the efficacy improves with the surgeon's experience, satisfactory outcome will only be obtained in a center performing a sufficient volume of esophageal surgery to provide the surgeon with opportunities to refine his necessary skills. Improvements in technique and instrumentation should make the procedure more accessible and steepen the learning curve.

    Between 1980 and 1994, 423 patients with esophageal cancer were given curative radiation therapy. Of these patients, 31 died of massive hemorrhage and were used as the subjects of analysis in this study. The incidence of massive hemorrhage in all patients was 7% (31/423). In the 31 patients who died of massive hemorrhage, 27 had local tumors and two had no tumors at hemorrhage (two unknown cases). The mean time interval from the start of radiation to hemorrhage was 9.2 months. In 9 autopsy cases the origin of hemorrhage was a tear of the aorta in 5 cases, necrotic local tumor in 3 cases and esophageal ulcer in 1 case. The positive risk factors for this complication seemed to be excess total dose, infection, metallic stent, and tracheoesophageal fistula. Chest pain or sentinel hemorrhage proceeding to massive hemorrhage was observed in about half of the patients. (orig.)

    Esophageal cancers are highly malignant tumours with often a poor prognosis, except for minimal lesions treated with surgery. Radiation therapy, or combined radiation and chemotherapy is the most used therapeutic modality, alone or before oesophagectomy. The delineation of target volumes is now more accurate owing the possibility to use routinely the new imaging techniques (mainly PET). The aim of this work is to precise the radio-anatomical particularities, the pattern of spread of esophageal cancer and the principles of 3D conformal radiotherapy illustrated with a clinical case.

There has been a sharp increase in the frequency of esophageal adenocarcinoma and a decline in the frequency of squamous cell carcinoma. A more comprehensive understanding of prognostic factors influencing outcome has also been developed. This has led to more management options for esophageal cancer at all stages than ever before. A multidisciplinary, team approach to management in a high volume center is the preferred approach. Each patient should be individually assessed based on type of cancer, local or regional involvement, and his or her own functional status to determine an appropriate treatment regimen. This review will discuss management of esophageal cancer relative to disease progression and patient functional status.Keywords: esophageal adenocarcinoma, squamous cell carcinoma, treatment regimen, disease progression, patient functional status

    Thoracoscopic esophagectomy is only established in some centers and affords a cervical anastomosis because intrathoracic anastomosis as a routine is technically too difficult. Laparoscopic mobilisation of the stomach (gastrolysis) is an important contribution for minimal invasive surgery of esophageal cancer.This procedure reduces the stress of the two cavity operation for the patient and allows the construction of a comparable gastric conduit like by open surgery. The technique of laparoscopic gastrolysis as preparation for transthoracic en bloc esophagectomy is described in detail and preliminary results are briefly mentioned.

    Full Text Available Esophageal cancer usually is discovered at a late stage and curative therapy seldom is possible. The prognosis is poor and most therapy is palliative. Endoscopic therapy commonly is employed; two common treatments involve thermal modalities. The Nd:YAG laser has been employed for 10 years and is effective in relieving obstruction in approximately 90% of cases. Re-ohstruction usually occurs in two to three months and repeat treatment may be necessary. Limitations to laser use include the fact that equipment is expensive and there are technical restrictions. An alternative thermal modality is the bipolar coagulation tumour probe which employs bipolar electrocoagulation. It is less expensive and, if the tumour is circumferential, tends to be easier to use. (It should not be used if the cancer is noncircumferential. The advantages and limitations of each modality are addressed.

    Intramural metastasis (IM) of esophageal cancer is defined as metastasis from a primary lesion to the esophageal wall without intraepithelial cancer extension. Esophageal cancer with IM is more common and such cases indicate a poor prognosis. In esophageal surgery, if curative resection is possible, the complete removal of both primary tumor and associated IMs is required. Therefore, accurate diagnosis of IMs in esophageal cancer prior to surgery is of particular importance. Multiphoton microscopy (MPM) with subcellular resolution is well-suited for deep tissue imaging since many endogenous fluorophores of fresh biological tissues are excited through two-photon excited fluorescence (TPEF) and second harmonic generation (SHG). Here, a study to identify IM in fresh tissue section using MPM is reported. In this study, the morphological and spectral differences between IM and surrounding tissue are described. These results show that MPM has the ability to accurately identify IM in esophageal tissues. With improvement of the penetration depth of MPM and the development of multiphton microendoscope, MPM may be a promising imaging technique for preoperative diagnosis of IMs in esophageal cancer in the future.

    Full Text Available BACKGROUND: Most inoperable patients with esophageal-advanced cancer (EGC have a poor prognosis. Esophageal stenting, as part of a palliative therapy management has dramatically improved the quality of live of EGC patients. Airway stenting is generally proposed in case of esophageal stent complication, with a high failure rate. The study was conducted to assess the efficacy and safety of scheduled and non-scheduled airway stenting in case of indicated esophageal stenting for EGC. METHODS AND FINDINGS: The study is an observational study conducted in pulmonary and gastroenterology endoscopy units. Consecutive patients with EGC were referred to endoscopy units. We analyzed the outcome of airway stenting in patients with esophageal stent indication admitted in emergency or with a scheduled intervention. Forty-four patients (58+/-\\-8 years of age with esophageal stenting indication were investigated. Seven patients (group 1 were admitted in emergency due to esophageal stent complication in the airway (4 fistulas, 3 cases with malignant infiltration and compression. Airway stenting failed for 5 patients. Thirty-seven remaining patients had a scheduled stenting procedure (group 2: stent was inserted for 13 patients with tracheal or bronchial malignant infiltration, 12 patients with fistulas, and 12 patients with airway extrinsic compression (preventive indication. Stenting the airway was well tolerated. Life-threatening complications were related to group 1. Overall mean survival was 26+/-10 weeks and was significantly shorter in group 1 (6+/-7.6 weeks than in group 2 (28+/-11 weeks, p<0.001. Scheduled double stenting significantly improved symptoms (95% at day 7 with a low complication rate (13%, and achieved a specific cancer treatment (84% in most cases. CONCLUSION: Stenting the airway should always be considered in case of esophageal stent indication. A multidisciplinary approach with initial airway evaluation improved prognosis and decreased

    We investigated whether the incidence of brain metastasis (BM) from primary esophageal and esophagogastric cancer is increasing. A single-institution retrospective review identified 583 patients treated from January 1997 to January 2016 for stages I through IV cancer of the esophagus and esophagogastric junction (follow-up, ≥3 months). Collected data included demographic information, date and staging at primary diagnosis, histologic subtype, treatment regimen for primary lesion, date of BM diagnosis, presence or absence of central nervous system symptoms, presence or absence of extracranial disease, treatment regimen for intracranial lesions, and date of death. The overall cohort included 495 patients (85%) with adenocarcinoma and 82 (14%) with squamous cell carcinoma (492 [84%] were male; median age at diagnosis, 68 years [range: 26-90 years]). BM was identified in 22 patients (3.8%) (median latency after primary diagnosis, 11 months). Among patients with BM, the primary histology was adenocarcinoma in 21 and squamous cell carcinoma in 1 (P = 0.30). BM developed in 12 who were initially treated for locally advanced disease and in 10 stage IV patients who presented with distant metastases. Overall survival (OS) after BM diagnosis was 18% at 1 year (median, 4 months). No difference in OS after BM diagnosis was observed in patients initially treated for localized disease compared to patients who presented with stage IV disease; however, OS was superior for patients who initially had surgical resection compared to patients treated with whole brain radiotherapy or stereotactic radiosurgery alone (1-year OS, 67% vs. 0%; median OS, 13.5 vs. 3 months; P = 0.003). The incidence of BM is low in patients with esophageal cancer. Outcomes were poor overall for patients with BM, but patients who underwent neurosurgical resection had improved survival. © The Authors 2017.

    Purpose/Objective(s): Current guidelines for esophageal cancer contouring are derived from traditional 2-dimensional fields based on bony landmarks, and they do not provide sufficient anatomic detail to ensure consistent contouring for more conformal radiation therapy techniques such as intensity modulated radiation therapy (IMRT). Therefore, we convened an expert panel with the specific aim to derive contouring guidelines and generate an atlas for the clinical target volume (CTV) in esophageal or gastroesophageal junction (GEJ) cancer. Methods and Materials: Eight expert academically based gastrointestinal radiation oncologists participated. Three sample cases were chosen: a GEJ cancer, a distal esophageal cancer, and a mid-upper esophageal cancer. Uniform computed tomographic (CT) simulation datasets and accompanying diagnostic positron emission tomographic/CT images were distributed to each expert, and the expert was instructed to generate gross tumor volume (GTV) and CTV contours for each case. All contours were aggregated and subjected to quantitative analysis to assess the degree of concordance between experts and to generate draft consensus contours. The panel then refined these contours to generate the contouring atlas. Results: The κ statistics indicated substantial agreement between panelists for each of the 3 test cases. A consensus CTV atlas was generated for the 3 test cases, each representing common anatomic presentations of esophageal cancer. The panel agreed on guidelines and principles to facilitate the generalizability of the atlas to individual cases. Conclusions: This expert panel successfully reached agreement on contouring guidelines for esophageal and GEJ IMRT and generated a reference CTV atlas. This atlas will serve as a reference for IMRT contours for clinical practice and prospective trial design. Subsequent patterns of failure analyses of clinical datasets using these guidelines may require modification in the future.

    Purpose/Objective(s) Current guidelines for esophageal cancer contouring are derived from traditional two-dimensional fields based on bony landmarks, and do not provide sufficient anatomical detail to ensure consistent contouring for more conformal radiotherapy techniques such as intensity-modulated radiation therapy (IMRT). Therefore, we convened an expert panel with the specific aim to derive contouring guidelines and generate an atlas for the clinical target volume (CTV) in esophageal or gastroesophageal junction (GEJ) cancer. Methods and Materials Eight expert academically-based gastrointestinal radiation oncologists participated. Three sample cases were chosen: a GEJ cancer, a distal esophageal cancer, and a mid-upper esophageal cancer. Uniform CT simulation datasets and an accompanying diagnostic PET-CT were distributed to each expert, and he/she was instructed to generate gross tumor volume (GTV) and CTV contours for each case. All contours were aggregated and subjected to quantitative analysis to assess the degree of concordance between experts and generate draft consensus contours. The panel then refined these contours to generate the contouring atlas. Results Kappa statistics indicated substantial agreement between panelists for each of the three test cases. A consensus CTV atlas was generated for the three test cases, each representing common anatomic presentations of esophageal cancer. The panel agreed on guidelines and principles to facilitate the generalizability of the atlas to individual cases. Conclusions This expert panel successfully reached agreement on contouring guidelines for esophageal and GEJ IMRT and generated a reference CTV atlas. This atlas will serve as a reference for IMRT contours for clinical practice and prospective trial design. Subsequent patterns of failure analyses of clinical datasets utilizing these guidelines may require modification in the future. PMID:26104943

    Objective:To find an effective treatment for advanced cancer patients with esophageal fistula. Methods:From 1998 to 2006, we studied 42 patients with advanced esophageal cancer and 5 lung cancer patients with carcinomatous esophageal fistula(3 females,44 males,aged 29-92 years). Ten patients with both esophageal cancer stricture and fistula were first dilated under endoscope,then a memory stent with a membrane was placed in the esophageal lumen. Others were treated only with a memory stent with a membrane,three of them with a large fistula(diameter>1.5 cm)were treated with bio-protein glue after placement of an esophageal metal stent.Results:The fistulas were covered by a stent and the patients could eat and drink immediately.Their quality of life was improved and their survival was prolonged, 44 out of 47 patients survived for>3 mo. Conclusion:Placement of esophageal stent with membrane or in combination with bio-protein glue through endoscope is an effective method for treating the bronchoesophageal fistula.

    Radiation therapy (RT) as part of multidisciplinary oncologic care has been marked by profound advancements over the past decades. As part of multimodality therapy for esophageal cancer (EC), a prime goal of RT is to minimize not only treatment toxicities, but also postoperative complications and hospitalizations. Herein, discussion commences with the historical approaches to treating EC, including seminal trials supporting multimodality therapy. Subsequently, the impact of RT techniques, including three-dimensional conformal RT, intensity-modulated RT, and proton beam therapy, is examined through available data. We further discuss existing data and the potential for further development in the future, with an appraisal of the future outlook of technological advancements of RT for EC. PMID:27775643

    Full Text Available CONTEXT: Esophageal cancer is often diagnosed at an advanced stage and has a poor prognosis. Most patients with advanced esophageal cancer have significant dysphagia that contributes to weight loss and malnutrition. Esophageal stenting is a widespread palliation approach, but unsuitable for cancers near the upper esophageal sphincter, were stents are poorly tolerated. Generally, guidelines do not support endoscopic gastrostomy in this clinical setting, but it may be the best option for nutritional support. OBJECTIVE: Retrospective evaluation of patients with dysphagia caused advanced esophageal cancer, no expectation of resuming oral intake and with percutaneous endoscopic gastrostomy for comfort palliative nutrition. METHOD: We selected adult patients with unresecable esophageal cancer histological confirmed, in whom stenting was impossible due to proximal location, and chemotherapy or radiotherapy were palliative, using gastrostomy for enteral nutrition. Clinical and nutritional data were evaluated, including success of gastrostomy, procedure complications and survival after percutaneous endoscopic gastrostomy, and evolution of body mass index, albumin, transferrin and cholesterol. RESULTS: Seventeen males with stage III or IV squamous cell carcinoma fulfilled the inclusion criteria. Mean age was 60.9 years. Most of the patients had toxic habits. All underwent palliative chemotherapy or radiotherapy. Gastrostomy was successfully performed in all, but nine required prior dilatation. Most had the gastrostomy within 2 months after diagnosis. There was a buried bumper syndrome treated with tube replacement and four minor complications. There were no cases of implantation metastases or procedure related mortality. Two patients were lost and 12 died. Mean survival of deceased patients was 5.9 months. Three patients are alive 6, 14 and 17 months after the gastrostomy procedure, still increasing the mean survival. Mean body mass index and laboratory

    In year 2000, a book entitled the Pathology and Genetics of Tumors of the Digestive System was published by the WHO, presenting some new diagnostic criteria and treatment principles. I have analyzed the epidemiologic change of tumors in over 30 years in the high-risk area with esophageal cancer. The following phenomenon was found: accompanied by the sharp decrease in the incidence and mortality of esophageal cancer, there was an increase in the incidence and death rate of stomach cancer involving cardiac cancer. This fact should be considered when analyzing the sharp decrease in esophageal cancer incidence and mortality rate. More attention was given to diagnosis of cardiac cancer; at the same time it is more practical to improve the early screening of cancers. To observe the development of high and lowgrade intraepithelial neoplasms will be an urgent task for esophageal cancer research in the high risk area, according to WHO's new classification.

    About 1500 high-risk subjects of esophageal cancer were found during screening by balloon cytology and all of them were examined endoscopically. Among them, 120 were considered as having early esophageal cancer and precancerous lesions. During the examination, Lugol's solution staining was used and guiding biopsy was taken. 98 subjects with unstained lesions were found, and biopsy showed early esophageal cancer in 60 (61.2%) and moderate and severe dysplasia in 38 (38.8%). It is usually extremely difficult to detect and localize the very early esophageal mucosal and submucosal carcinoma. But endoscopic examination and using Lugol's solution staining with multiple spots biopsy from unstained area are of great assistance. Minute malignant lesions may not be overlooked.

    Elisa Boldrin

    Full Text Available BACKGROUND: Development of novel therapeutic drugs and regimens for cancer treatment has led to improvements in patient long-term survival. This success has, however, been accompanied by the increased occurrence of second primary cancers. Indeed, patients who received regional radiotherapy for Hodgkin's Lymphoma (HL or breast cancer may develop, many years later, a solid metachronous tumor in the irradiated field. Despite extensive epidemiological studies, little information is available on the genetic changes involved in the pathogenesis of these solid therapy-related neoplasms. METHODS: Using microsatellite markers located in 7 chromosomal regions frequently deleted in sporadic esophageal cancer, we investigated loss of heterozygosity (LOH and microsatellite instability (MSI in 46 paired (normal and tumor samples. Twenty samples were of esophageal carcinoma developed in HL or breast cancer long-term survivors: 14 squamous cell carcinomas (ESCC and 6 adenocarcinomas (EADC, while 26 samples, used as control, were of sporadic esophageal cancer (15 ESCC and 11 EADC. RESULTS: We found that, though the overall LOH frequency at the studied chromosomal regions was similar among metachronous and sporadic tumors, the latter exhibited a statistically different higher LOH frequency at 17q21.31 (p = 0.018. By stratifying for tumor histotype we observed that LOH at 3p24.1, 5q11.2 and 9p21.3 were more frequent in ESCC than in EADC suggesting a different role of the genetic determinants located nearby these regions in the development of the two esophageal cancer histotypes. CONCLUSIONS: Altogether, our results strengthen the genetic diversity among ESCC and EADC whether they occurred spontaneously or after therapeutic treatments. The presence of histotype-specific alterations in esophageal carcinoma arisen in HL or breast cancer long-term survivors suggests that their transformation process, though the putative different etiological origin, may retrace

  18. DDEC: Dragon database of genes implicated in esophageal cancer

    KAUST Repository

    Essack, Magbubah

    2009-07-06

    Background: Esophageal cancer ranks eighth in order of cancer occurrence. Its lethality primarily stems from inability to detect the disease during the early organ-confined stage and the lack of effective therapies for advanced-stage disease. Moreover, the understanding of molecular processes involved in esophageal cancer is not complete, hampering the development of efficient diagnostics and therapy. Efforts made by the scientific community to improve the survival rate of esophageal cancer have resulted in a wealth of scattered information that is difficult to find and not easily amendable to data-mining. To reduce this gap and to complement available cancer related bioinformatic resources, we have developed a comprehensive database (Dragon Database of Genes Implicated in Esophageal Cancer) with esophageal cancer related information, as an integrated knowledge database aimed at representing a gateway to esophageal cancer related data. Description: Manually curated 529 genes differentially expressed in EC are contained in the database. We extracted and analyzed the promoter regions of these genes and complemented gene-related information with transcription factors that potentially control them. We further, precompiled text-mined and data-mined reports about each of these genes to allow for easy exploration of information about associations of EC-implicated genes with other human genes and proteins, metabolites and enzymes, toxins, chemicals with pharmacological effects, disease concepts and human anatomy. The resulting database, DDEC, has a useful feature to display potential associations that are rarely reported and thus difficult to identify. Moreover, DDEC enables inspection of potentially new \\'association hypotheses\\' generated based on the precompiled reports. Conclusion: We hope that this resource will serve as a useful complement to the existing public resources and as a good starting point for researchers and physicians interested in EC genetics. DDEC is

    We report a rare case of advanced carcinoma and a second primary carcinoma of the esophagus, both of which were successfully cured by chemotherapy and operation at different times. In 1991, a 38-year-old Japanese man was diagnosed with advanced esophageal cancer, which was unresectable because of the bronchial invasion of the tumor. He was given chemotherapy with cisplatin (CDDP), combined with radiotherapy. During a 4-year follow-up, neither regrowth of the primary tumor nor distant metastasis occurred. In 1995, esophagoscopy demonstrated a lugol-unstained region located 3 cm distal from the area of radiation to the primary lesion shown by esophagography. Histological examination of a biopsy specimen showed the mucosa to be normal. Nevertheless, yearly surveillance by endoscopy and histological examinations showed that the mucosa of the esophagus gradually began to demonstrate mild dysplasia, followed by severe dysplasia; in 1998, a diagnosis of squamous cell carcinoma was made. Esophagectomy with lymph node dissection was performed. Microscopic examination revealed that there had been pathologic complete response for the original advanced esophageal cancer. (author)

    Full Text Available Background. While the surface of a cell normally has some amount of somatostatin receptors, these receptors are overexpressed to a very high degree in multiple neoplastic diseases. No data exist for esophageal carcinoma. Purpose. To find out whether esophageal carcinoma could be imaged using somatostatin receptor scintigraphy. Material and Methods. 34 patients with esophageal lesions were prospectively examined by 99mTc-depreotide scintigraphy 2 and 4 hours after injection. Quantitative evaluation of 99mTc-depreotide uptake was performed around the lesion (T and in healthy lung parenchyma (B. The relative uptake was calculated as T−B/B. Scintigraphy results were compared with histopathology from surgery or biopsy specimens from endoscopic ultrasonography. Results. 21 patients had esophageal cancer, and 13 lesions were benign. Visual assessment revealed positive 99mTc-depreotide uptake in 16 of the 21 cancers. The 13 patients without cancer had no depreotide uptake. The Mann-Whitney U test showed a statistically significant difference (<.005 between 99mTc-depreotide uptake in malignant and benign lesions, for both the 2-hour and the 4-hour measurements. Conclusion. Scintigraphic examination with 99mTc-depreotide is feasible for imaging esophageal cancer, but the method is not suitable neither for screening or primary diagnosis, because of methods modest sensitivity. Our first results showed high specificity which should be used with caution, as the number of patients was relatively low. Further studies are needed to determine the role of the method.

    Fifty-two patients with advanced esophageal cancer have been entered in an open study with vindesine. The regimen consisted of vindesine at a dose of 3 mg/m2 as a continuous infusion over 48 hours followed by 3 mg/m2 iv weekly for 4 weeks and then by monthly maintenance therapy using the same dose. Objective response was seen in 14 (27%) patients. Patients who responded to treatment had significant prolongation of survival. Major pretreatment prognostic factors included performance status and serum albumin concentration. It is concluded that vindesine has definite, although limited, activity against esophageal cancer.

    In order to obtain a reliable experimental model simulating human esophageal cancer, endoscopic and histopathological studies were undertaken in the esophageal cancer produced in the beagle dog. Thirty-seven dogs had been given a solution of N-Ethyl-N'-nitro-N-nitrosoguanidine (ENNG) at a concentration of 150 micrograms/ml for 3-9 months. Follow-up studies included serial endoscopy and biopsy, and almost all animals were eventually sacrificed for histological examination. The results were as follows: Squamous cell carcinoma was observed in 5 out of 22 female dogs, while none in male dogs at all. For the induction of squamous cell carcinoma in the esophagus, administration in the condition of 150 micrograms/ml (75mg/day) for 6-9 months was most suitable. Almost all of esophageal lesions were protruding and well-differentiated squamous cell carcinoma with invasion of the submucosa. The stages of hyperplasia, dysplasia and squamous cell carcinoma in the esophagus were chronologically followed. Carcinoma had been observed in the stomach about 4 months prior to the appearance of esophageal carcinoma. This experimental model was proved to be useful for studies on histogenesis of human esophageal cancer both light and electron microscopically.

    Green tea contains high concentrations of tea polyphenols that have shown inhibitory effects against the development, progress, and growth of carcinogen-induced tumors in animal models at different organ sites, including the esophagus and lung. Green tea polyphenols also have shown to suppress cell proliferation and induce apoptosis. Besides antioxidative property, green tea polyphenols have pro-oxidative activities under certain conditions and modulate phase II metabolic enzymes that can enhance the detoxification pathway of environmental toxicants and carcinogens. Although epidemiological studies have provided inconclusive results on the effect of green tea consumption against the development of esophageal and lung cancers in humans overall, the inverse association between green tea intake and risk of esophageal cancer risk is more consistently observed in studies with adequate control for potential confounders. Epidemiological studies also have demonstrated an inverse, albeit moderate, association between green tea consumption and lung cancer, especially in non-smokers. This article reviews data on the cancer-preventive activities of green tea extract and green tea polyphenols and possible mechanisms against the esophageal and lung carcinogenesis in experimental animals, and summarizes the current knowledge from epidemiological studies on the relationship between green tea consumption and esophageal and lung cancer risk in humans.

    Epidemiological studies have demonstrated that areca quid chewing can be an independent risk factor for developing esophageal cancer. However, no studies are available to elucidate the mechanisms of how areca induces carcinogenesis in the esophagus. Since the areca nut in Taiwan contains a high concentration of safrole, a well-known carcinogenic agent, we analyzed safrole-DNA adducts by the 32P-postlabelling method in tissue specimens from esophageal cancer patients. In total, we evaluated 47 patients with esophageal cancer (16 areca chewers and 31 non-chewers) who underwent esophagectomy at the National Taiwan University Hospital between 1996 and 2002. Of the individuals with a history of habitual areca chewing (14 cigarette smokers and two non-smokers), one of the tumor tissue samples and five of the normal esophageal mucosa samples were positive for safrole-DNA adducts. All patients positive for safrole-DNA adducts were also cigarette smokers. Such adducts could not be found in patients who did not chew areca, irrespective of their habits of alcohol consumption or cigarette smoking (psafrole was also tested in vitro in three esophageal cell lines and four cultures of primary esophageal keratinocytes. In two of the esophageal keratinocyte cultures, adduct formation was increased by treatment with safrole after induction of cytochrome P450 by 3-methyl-cholanthrene. This paper provides the first observation of how areca induces esophageal carcinogenesis, i.e., through the genotoxicity of safrole, a component of the areca juice.

    Nutritional status and body composition parameters such as sarcopenia are important risk factors for impaired outcome in patients with esophageal cancer. This study was conducted to evaluate the effect of sarcopenia on long-term outcome after esophageal resection following neoadjuvant treatment. Skeletal muscle index (SMI) and body composition parameters were measured in patients receiving neoadjuvant treatment for locally advanced esophageal cancer. Endpoints included relapse-free survival (RFS) and overall survival (OS). The study included 130 patients. Sarcopenia was found in 80 patients (61.5%). Patients with squamous-cell cancer (SCC) showed a decreased median SMI of 48 (range 28.4-60.8) cm/m(2) compared with that of patients with adenocarcinoma (AC) of 52 (range 34.4-74.2) cm/m(2), P sarcopenia had a significant impact on patient outcome: HR 1.69 (1.04-2.75), P = 0.036. Median OS was 20.5 (7.36-33.64) versus 52.1 (13.55-90.65) months in sarcopenic and non-sarcopenic patients, respectively. Sarcopenia was identified as an independent risk factor: HR 1.72 (1.049-2.83), P = 0.032. Our data provide evidence that sarcopenia impacts long-term outcome after esophageal resection in patients who have undergone neoadjuvant therapy. Assessment of the body composition parameter can be a reasonable part of patient selection and may influence treatment methods.

    Survival of esophageal cancer generally is poor but has been improving. Induction chemoradiation is recommended before esophagectomy for locally advanced squamous cell carcinoma. Both induction chemotherapy and induction chemoradiation are found to be beneficial for locally advanced adenocarcinoma. Although a clear advantage of either strategy has not yet been demonstrated, consensus-based guidelines recommend induction chemoradiation for locally advanced adenocarcinoma.

    Esophageal fistula is a critical adverse event in patients treated with chemoradiotherapy (CRT) for locally advanced esophageal cancer. However, risk factors associated with esophageal fistula formation in patients receiving CRT have not yet been elucidated.We retrospectively analyzed data obtained from 140 patients who were enrolled in a phase II/III trial comparing low-dose cisplatin with standard-dose cisplatin administered in combination with 5-flurouracil and concomitant radiotherapy. Inclusion criteria were performance status (PS) 0 to 2 and histologically proven thoracic esophageal cancer clinically diagnosed as T4 and/or unresectable lymph node metastasis for which definitive CRT was applicable. Risk factors for esophageal fistula were examined with univariate analysis using Fisher exact test and multivariate analysis using logistic regression models.Esophageal fistula was observed in 31 patients (22%). Of these, 6 patients developed fistula during CRT. Median time interval between the date of CRT initiation and that of fistula diagnosis was 100 days (inter quartile range, 45-171). Esophageal stenosis was the only significant risk factor for esophageal fistula formation both in univariate (P = 0.026) and in multivariate analyses (odds ratio, 2.59; 95% confidence interval, 1.13-5.92, P = 0.025). Other clinicopathological factors, namely treatment arm, age, sex, PS, primary tumor location, T stage, lymph node invasion to adjacent organs, blood cell count, albumin level, and body mass index, were not risk factors fistula formation.Esophageal stenosis was a significant risk factor for esophageal fistula formation in patients treated with CRT for unresectable locally advanced thoracic esophageal squamous cell carcinoma.

    In patients with operable esophageal cancer, there is evidence supporting the use of preoperative chemotherapy or preoperative chemoradiation. The addition of radiotherapy to chemotherapy seems more relevant for the more locally advanced cancers. There is a need to examine in trials more modern chemotherapy combinations with and without concurrent radiation and for research into assessing methods for predicting outcomes from neoadjuvant therapy as part of the paradigm of therapy for this disease.

    We prospectively investigated dietary flavonoid intake and esophageal cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. The study included 477,312 adult subjects from 10 European countries. At baseline, country-specific validated dietary questionnaires...... were used. During a mean follow-up of 11 years (1992-2010), there were 341 incident esophageal cancer cases, of which 142 were esophageal adenocarcinoma (EAC), 176 were esophageal squamous cell carcinoma (ESCC), and 23 were other types of esophageal cancer. In crude models, a doubling in total dietary...... associated with esophageal cancer risk. No associations were found in either never or former smokers. These findings suggest that dietary flavonoid intake was not associated with overall esophageal cancer, EAC, or ESCC risk, although total flavonoids and some flavonoid subclasses, particularly flavonols, may...

    A 67-year-old man was admitted to our hospital for treatment for multiple superficial esophageal cancers. Screening upper gastrointestinal endoscopy examination revealed a superficial squamous cell carcinoma (SCC) at the middle thoracic esophagus and Barrett's epithelium and a superficial adenocarcinoma at the abdominal esophagus. We performed a subtotal esophagectomy with gastric tube reconstruction via the retrosternal route. Pathological examination revealed a Barrett's adenocarcinoma at the abdominal esophagus. Esophageal cancer is thought to be a multicentric disease, and we sometimes find multiple esophageal cancers. In Japan, most cases of multiple esophageal cancers are composed of SCCs, and the occurrence of multiple esophageal cancers composed of SCC and Barrett's adenocarcinoma is rare. In contrast, the number of the patients with Barrett's esophagus is increasing, and the number of the patients with Barrett's adenocarcinoma also seems to be on the rise. Therefore, it is important be aware of the possibility of multiple esophageal cancers composed of SCC and Barrett's adenocarcinoma while making diagnoses.

    Esophageal cancer treatment has evolved from single modality to trimodality therapy.There are some controversies of the role,target volumes and dose of radiotherapy(RT)in the literature over decades.The present review focuses primarily on RT as part of the treatment modalities,and highlight on the RT volume and its dose in the management of esophageal cancer.The randomized adjuvant chemoradiation(CRT)trial,intergroup trial(INT 0116)enrolled 559 patients with resected adenocarcinoma of the stomach or gastroesophageal junction.They were randomly assigned to surgery plus postoperative CRT or surgery alone.Analyses show robust treatment benefit of adjuvant CRT in most subsets for postoperative CRT.The Chemoradiotherapy for Oesophageal Cancer Followed by Surgery Study(CROSS)used a lower RT dose of41.4 Gray in 23 fractions with newer chemotherapeutic agents carboplatin and paclitaxel to achieve an excellent result.Target volume of external beam radiation therapy and its coverage have been in debate for years among radiation oncologists.Pre-operative and postoperative target volumes are designed to optimize for disease control.Esophageal brachytherapy is effective in the palliation of dysphagia,but should not be given concomitantly with chemotherapy or external beam RT.The role of brachytherapy in multimodality management requires further investigation.On-going studies of multidisciplinary treatment in locally advanced cancer include:ZTOG1201 trial(a phaseⅡtrial of neoadjuvant and adjuvant CRT)and QUINTETT(a phaseⅢtrial of neoadjuvant vs adjuvant therapy with quality of life analysis).These trials hopefully will shed more light on the future management of esophageal cancer.

    AIM: To determine the outcome of esophageal cancer patients referred for palliative care, in Gorgan and Gonbad gastrointestinal clinics, northeast of Iran.METHODS: This cross-sectional study was done on inoperable esophageal cancer cases referred to gastrointestinal clinics in Gorgan and Gonbad city (2005-2006). Demographic data were collected during the procedure and cases were followed up every one month. Improvement proportion was calculated with 95% confidence interval, to determine the rate of improvement. Survival analysis and Kaplan-Meier methods were used to estimate the duration of palliative care effectiveness.RESULTS: We recruited 39 cases into the study. Squamous cell carcinoma was the most prevalent (92.3%). The middle third of the esophagus was involved predominantly (51.3%). Dilation was the most preferred method (89.7%) and stenting was done in 4 cases. Decreasing dysphagia score was not related to palliation method or pathology type of carcinoma. Age of the patients was significantly related to the improvement of dysphagia score. Mean survival time was 137.6d and median was 103d.CONCLUSION: Results of this study showed a low survival rate after palliative care in esophageal cancer cases despite dysphagia scores' improvement after dilating or stenting.

    Retinoblastoma(RB) gene is the prototype of tumor suppressor gene and it`s alteration have been frequently observed in a large number of human tumors. To investigate the role of RB in esophageal cancer, we studied 36 esophageal cancer tissues with Southern blot analysis to detect gross LOH and PCR-SSCP method to find minute LOH and mutation, if any. In the cases with abnormalities, the nucleotide sequence analysis was performed. Allelic loss of chromosome 13q14 occurred in 20 out of 32 informative cases (62.5%) by Southern analysis. Furthermore, PCR-LOH added three positive cases. Mobility shift by PCR-SSCP was observed in one case at exon 22, which showed 1 bp deletion in codon 771 of RB gene resulting in frame shift mutation. Besides, nine PCR-band alteration in tumor tissue compared with normal tissue were observed in exon 14 and 22, but mutation was not found on sequencing analysis suggesting the epigenetic alteration in tumor tissue. Analysis of the clinical data did not show any difference depending upon RB alteration. However, the total incidence of RB gene may play an important role in the development of esophageal cancer. The main genetic alteration of RB gene was deletion detected by Southern blot and one bp deletion leading to frame shift was also observed. 8 figs, 5 tabs. (Author).

    Patients with locally advanced esophageal cancer have a dismal prognosis when treated exclusively by surgery. This fact prompted many investigators to apply neoadjuvant treatment strategies in an effort to improve survival. Results from phase Ⅲ randomized trials are encouraging however, they revealed that only patients with major histopathological response will benefit from treatment. Therefore, predictive molecular markers indicating response or non-response to neoadjuvant treatment would be extremely helpful in selecting patients for current and future treatment protocols. In this paper we review the role of the molecular markers ERCC1 (excision repair cross-complementing 1 gene) and c-erbB-2 (synonym:HER2/neu) in predicting response to radiochemotherapy and outcome for patients with locally advanced resectable esophageal cancers (cT2-4, Nx, M0). The results are promising and it appears that we might expect to unequivocally identify with ERCC1 and c-erbB-2 respectively, approximately up to one third of patients who fulfil the criteria for neoadjuvant treatment for locally advanced esophageal cancer but will not benefit from our treatment protocol. Integration of such markers in the clinical setting might prevent a substantial number of patients from expensive, non-effective and potentially harmful therapies, and could lead to a more individualized type of combined multimodality treatment in the near future.

    Full Text Available Endoscopic submucosal dissection (ESD for the treatment of esophageal mucosal lesions is associated with a risk of esophageal stenosis, especially for near-circumferential or circumferential esophageal mucosal defects. Here, we review historic and modern studies on the prevention and treatment of esophageal stenosis after ESD. These methods include prevention via pharmacological treatment, endoscopic autologous cell transplantation, endoscopic esophageal dilatation, and stent placement. This short review will focus on direct prevention and treatment, which may help guide the way forward.

    Full Text Available Background. Since neoadjuvant treatment in esophageal cancer began to become popular, a complete pathological response at the primary tumour site has been commonly reported. An issue of conflict is whether complete response in the esophageal lumen means that the esophagus is completely tumour-free. Another important issue is whether lymph nodes that are retrieved from pathologically complete response cases are also tumour-free or not. There is a gap in the esophageal cancer staging system for ypT0 N2 M0 tumours that have received neoadjuvant therapy. Here, we will discuss the problem about staging of esophageal cancer associated with neoadjuvant therapy. Case. A female aged 40 years complaining of dysphagia was diagnosed as having locally advanced thoracic esophageal cancer. Neoadjuvant therapy decision was taken by oncology committee. Six weeks after neoadjuvant therapy, with a curative intention, minimal invasive surgery was performed. The pathology report was as follows. “There were no neoplastic cells in the suspected area of the esophageal mucosa upon examination with all staining. There was no cancer at resection margins. Four metastatic lymph nodes were infiltrated with squamous cell cancer.” Conclusion. Despite the growing use of neoadjuvant treatment in locally advanced esophageal cancer in world, we do not have a protocol for the evaluation of these patients’ pathology reports. We believe that new studies and new ideas are needed to resolve this dilemma associated with neoadjuvant therapy.

    Shih-Han Hung

    Full Text Available BACKGROUND: This study attempted to reveal the incidence and risk of synchronous and metachronous esophageal cancer in subjects with oral, oropharyngeal and hypopharyngeal cancer based on a population-wide database in Taiwan. METHODS: We retrieved data for this cross-sectional study from the Taiwanese Longitudinal Health Insurance Database 2000. The study group included 2,965 subjects who had received their first-time diagnosis of oral/oropharyngeal/hypopharyngeal cancer in 2002∼2009. We assigned the date of their first diagnosis of oral/oropharyngeal/hypopharyngeal cancer as the index date. We also randomly retrieved 29,650 comparison subjects matched with the study subjects in terms of gender and age group. We assigned their first medical utilization that occurred in the index year as the index date for the comparison group. We further performed a conditional logistic regression to investigate the association between esophageal cancer and oral cancer. RESULTS: Results showed that prevalences of esophageal cancer within 3 months before and after the index date were respectively 2.19% and 0.04% for the study and comparison groups. A conditional logistic regression revealed that the odds ratio (OR of esophageal cancer for subjects with oral/oropharyngeal/hypopharyngeal cancer was 55.33 (95% confidence interval (CI: 29.86∼102.52 compared to comparison subjects. Furthermore, compared to comparison subjects, ORs for esophageal cancer were respectively 18.41 (95% CI: 8.50-39.85, 40.49 (95% CI: 15.11∼108.64, and 240.96 (95% CI: 125.49-462.69 for study subjects with a malignancy of the oral cavity, oropharynx, and hypopharynx. CONCLUSION: We concluded that there were relatively high chances for synchronous and metachronous esophageal cancers being detected through panendoscopy in patients with oral, oropharyngeal, and hypopharyngeal cancers. The routine use of panendoscopy in such patients should be encouraged with a higher priority.

    There are very few xenograft models available for the study of esophageal (E) and gastro-esophageal junction (GEJ) cancer. Using a NOD/SCID model, we implanted 90 primary E and GEJ tumors resected from patients and six endoscopic biopsy specimens. Of 69 resected tumors with histologically confirmed viable adenocarcinoma or squamous cell carcinoma, 22 (32%) was engrafted. One of 11 tumors, considered to have had a complete pathological response to neo-adjuvant chemo-radiation, also engrafted. Of the 23 patients whose tumors were engrafted, 65% were male; 30% were early stage while 70% were late stage; 22% received neo-adjuvant chemo-radiation; 61% were GEJ cancers. Engraftment occurred in 18/54 (33%) adenocarcinomas and 5/16 (31%) squamous cell carcinomas. Small endoscopic biopsy tissue had a 50% (3/6) engraftment rate. Of the factors analyzed, pretreatment with chemo-radiation and well/moderate differentiation showed significantly lower correlation with engraftment (P<0.05). In the subset of patients who did not receive neo-adjuvant chemo-radiation, 18/41 (44%) engrafted compared with those with pretreatment where 5/29 (17%, P=0.02) engrafted. Primary xenograft lines may be continued through 4-12 passages. Xenografts maintained similar histology and morphological characteristics with only minor variations even after multiple passaging in most instances.

  8. Differential expression analsis of matrix metallo-proteinase 20 (MMP20) in human esophageal cancer

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The aim of this study was to investigate the different expressions of MMP20 in the process of esophageal cancer. RT-PCR, immunohistochemistry and Western blot were employed to detect the mRNA expression and protein expression of MMP20. Compared with the corresponding normal esophagus tissues, results showed the common trend of the dramatical overexpression of MMP20 in the esopha-geal cancer tissues. The analysis of MMP20 expression in different clinical early stages of esophageal cancer by RT-PCR indicated that MMP20 was much more overexpressed in the esophageal cancer with invasion than in the early stages. This suggested that MMP20 might play an important role in the progression of esophageal cancer. It probably plays a critical role in tumor invasion.

    2015-07-01

    Esophageal cancer patients are often diagnosed as "advanced" cases. These patients are subjected to palliative stenting using self-expanding metallic stents (SEMS) to maintain oral alimentation. Unfortunately, SEMS get reoccluded due to tumor growth, in and over the stent struts. To investigate potential solutions to this problem, docetaxel (DTX) delivery films were prepared using PurSil AL 20 (PUS), which can be used as a covering material for the SEMS. Drug-polymer miscibility and interactions were studied. Bilayer films were prepared by adhering the blank film to the DTX loaded film in order to maintain the unidirectional delivery to the esophagus. In vitro release and the local DTX delivery were studied using in vitro permeation experiments. It was found that DTX and PUS were physically and chemically compatible. The bilayer films exhibited sustained release (>30 days) and minimal DTX permeation through esophageal tissues in vitro. The rate-determining step for the DTX delivery was calculated. It was found that >0.9 fraction of rate control lies with the esophageal tissues, suggesting that DTX delivery can be sustained for longer periods compared to the in vitro release observed. Thus, the bilayer films can be developed as a localized sustained delivery system in combination with the stent.

  10. Endoscopic mucosectomy: an alternative treatment for superficial esophageal cancer.

    Science.gov (United States)

    Lambert, R

    2000-01-01

    Recent trends in the management of superficial esophageal cancer consist of improved detection, pretherapeutic staging and reliable criteria for curative endoscopic therapy. The endoscopic treatment is legitimate when the cancer is at an early stage, intra-epithelial or microinvasive (m1 or m2) and N0. Submucosal cancer should not be treated with a curative intent by endotherapy. Concerning squamous cell cancer, the oriental and occidental pathologists include high-grade dysplasia in the same group as intramucosal cancer. The distinction is however maintained for adenocarcinoma in the Barrett's esophagus. Indications of endoscopic rather than surgical treatment rely on: (1) the small size of the tumor (not more than 2 cm in diameter); (2) the endoscopic morphology in the type 0 of the Japanese classification with the flat subtypes IIa and IIb rather than type IIc--there is high risk of submucosal invasion for the polypoid (type I) or ulcerated superficial cancer (type III); and (3) the endoscopic ultrasound staging, with confirmed integrity of the hyperechoic submucosal layer. The high-frequency (20 MHz) miniprobe is preferred to the standard (7.5 MHz) instrument. The elective procedure for tumor eradication is endoscopic mucosectomy. The technique is associated with a 6.8% risk of severe complications (hemorrhage or perforation) and a recurrence rate of 3%-7%. The 5-year survival rate is similar to that of surgery (over 80%). In the small group of patients with superficial esophageal cancer (less than 10% of the disease) endoscopic treatment may now be proposed in about 30% of cases, surgery is preferred for submucosal cancer and for neoplasia with a large surface. Areas of high-grade dysplasia in the Barrett's esophagus offer a new and increasing sector of indications. The concurrent endoscopic procedure of destruction--photodynamic therapy--is preferred for the destruction of lesions with poorly delineated limits.

    Purpose: We previously showed that 75% of radiation therapy (RT) failures in patients with unresectable esophageal cancer are in the gross tumor volume (GTV). We performed a planning study to evaluate if a simultaneous integrated boost (SIB) technique could selectively deliver a boost dose of radiation to the GTV in patients with esophageal cancer. Methods and Materials: Treatment plans were generated using four different approaches (two-dimensional conformal radiotherapy [2D-CRT] to 50.4 Gy, 2D-CRT to 64.8 Gy, intensity-modulated RT [IMRT] to 50.4 Gy, and SIB-IMRT to 64.8 Gy) and optimized for 10 patients with distal esophageal cancer. All plans were constructed to deliver the target dose in 28 fractions using heterogeneity corrections. Isodose distributions were evaluated for target coverage and normal tissue exposure. Results: The 50.4 Gy IMRT plan was associated with significant reductions in mean cardiac, pulmonary, and hepatic doses relative to the 50.4 Gy 2D-CRT plan. The 64.8 Gy SIB-IMRT plan produced a 28% increase in GTV dose and comparable normal tissue doses as the 50.4 Gy IMRT plan; compared with the 50.4 Gy 2D-CRT plan, the 64.8 Gy SIB-IMRT produced significant dose reductions to all critical structures (heart, lung, liver, and spinal cord). Conclusions: The use of SIB-IMRT allowed us to selectively increase the dose to the GTV, the area at highest risk of failure, while simultaneously reducing the dose to the normal heart, lung, and liver. Clinical implications warrant systematic evaluation.

    The aim of this study was to assess the 6-months dysphagia-free survival, improvement in swallowing function, complication rate, and overall survival in patients with incurable esophageal cancer treated with palliative radiotherapy. We retrospectively reviewed data from 139 patients (median age 72 years) with advanced/recurrent incurable esophageal cancer, who were referred to 3 German radiation oncology centers for palliative radiotherapy between 1994 and 2014. Radiotherapy consisted of external beam radiotherapy (EBRT) with 30 - 40.5 Gy/2.5 - 3 Gy per fraction, brachytherapy alone (BT) with 15 - 25 Gy/5 - 7Gy per fraction/weekly and EBRT + BT (30 - 40.5 Gy plus 10 - 14 Gy with BT) in 65, 46, and 28 patients, respectively. Dysphagia-free survival (Dy-PFS) was defined as the time to worsening of dysphagia for at least one point, a new loco-regional failure or death of any cause. Median follow-up time was 6 months (range 1-6 months). Subjective symptom relief was achieved in 72 % of patients with median response duration of 5 months. The 1-year survival rate was 30%. The 6-months Dy-PFS time for the whole group was 73 ± 4%. The 6-months Dy-PFS was 90 ± 4% after EBRT, 92 ± 5% after EBRT + BT and 37 ± 7% after BT, respectively (p<0.001). Five patients lived for more than 2 years, all of them were treated with EBRT ± BT. Ulceration, fistula and stricture developed in 3, 6 and 7 patients, respectively. Radiotherapy leads to symptom improvement in the majority of patients with advanced incurable esophageal cancer. The present results favor EBRT ± BT over BT alone. Due to the retrospective nature of this study, imbalances in baseline characteristics might have contributed to this finding, and further trials appear necessary.

    Full Text Available Abstract The spleen is an infrequent site for metastatic lesions, and solitary splenic metastases from squamous cell carcinoma of the esophagus are very rare: only 4 cases have been reported thus far. These lesions are whitish nodules that are macroscopically and radiologically similar to primary splenic lymphomas. We report a case of metachronous splenic metastases from esophageal cancer and multiple splenic abscesses, which developed nine months after apparently curative esophagectomy without adjuvant chemotherapy. The patient underwent splenectomy dissection followed by adjuvant chemotherapy, but liver and skin metastases developed, and the patient died 9 months later.

    Purpose: Proton beam therapy (PBT) is a promising modality for the management of thoracic malignancies. We report our preliminary experience of treating esophageal cancer patients with concurrent chemotherapy (CChT) and PBT (CChT/PBT) at MD Anderson Cancer Center. Methods and Materials: This is an analysis of 62 esophageal cancer patients enrolled on a prospective study evaluating normal tissue toxicity from CChT/PBT from 2006 to 2010. Patients were treated with passive scattering PBT with two- or three-field beam arrangement using 180 to 250 MV protons. We used the Kaplan-Meier method to assess time-to-event outcomes and compared the distributions between groups using the log-rank test. Results: The median follow-up time was 20.1 months for survivors. The median age was 68 years (range, 38-86). Most patients were males (82%) who had adenocarcinomas (76%) and Stage II-III disease (84%). The median radiation dose was 50.4 Gy (RBE [relative biologic equivalence]) (range, 36-57.6). The most common grade 2 to 3 acute toxicities from CChT/PBT were esophagitis (46.8%), fatigue (43.6%), nausea (33.9%), anorexia (30.1%), and radiation dermatitis (16.1%). There were two cases of grade 2 and 3 radiation pneumonitis and two cases of grade 5 toxicities. A total of 29 patients (46.8%) received preoperative CChT/PBT, with one postoperative death. The pathologic complete response (pCR) rate for the surgical cohort was 28%, and the pCR and near CR rates (0%-1% residual cells) were 50%. While there were significantly fewer local-regional recurrences in the preoperative group (3/29) than in the definitive CChT/PBT group (16/33) (log-rank test, p = 0.005), there were no differences in distant metastatic (DM)-free interval or overall survival (OS) between the two groups. Conclusions: This is the first report of patients treated with PBT/CChT for esophageal cancer. Our data suggest that this modality is associated with a few severe toxicities, but the pathologic response and clinical

    Over 3 years, concurrent chemoradiotherapy was performed in 16 patients with advanced esophageal cancer (clinical Stage IV) and suspected noncurative resection. The subjects were {>=}A3 or N3, or were stage IV with distant metastasis on preoperative diagnosis. Two courses of 5FU and CDDP were given with concurrent radiotherapy. The predominant side effects were nausea, vomiting and anorexia. Mild or moderate leukopenia also occurred. The response was complete remission (CR) in two patients, partial remission (PR) in eight, minor response (MR) in two, no change (NC) in two and progressive disease (PD) in two. The overall response rate was 62.5%. Esophagectomy was performed in four patients (histological stage II in one, stage III in one, and stage IV in two). Two of 4 resected patients are alive (33.8 months), while the other died of unrelated causes. One of the 6 non-resected PR patients has survived for 18 months, but all other patients died of cancer within nine months of starting treatment. The survival rate of 16 patients undergoing chemoradiotherapy was 16.7% at one and two years. Thus, chemoradiotherapy may improve the prognosis of advanced esophageal cancer with suspected noncurative resection by increasing the response rate and the curative resection rate. (author)

    Full Text Available Aim: Esophageal cancer remains a major and lethal health problem. In Nepal, not much has been explored about its management. The aim of this study was to conduct a retrospective review of esophageal cancer patients undergoing surgery or combined modality treatment at a cancer hospital in Nepal. Materials and Methods: Resectable cases were treated primarily with surgery. Locally advanced cases with doubtful or obviously unresectability underwent preoperative chemo/radiation or chemoradiation followed by surgery. Results: Among 900 patients, 103 were treated with curative intent. Mean age of patients was 54 years, and 100% of the patients presented with complaint of dysphagia. Surgery as a single modality of treatment was done in 57% of cases, and the remaining underwent combined modality treatment. Transthoracic and transhiatal approaches were used in 95% and 5% of cases, respectively. Nodal sampling, two-field (2-FD, and three-field lymphadenectomy (3-FD were done in 18%, 59%, and 20% of cases, respectively. A majority of patients had pathological stage III disease (46.6%. In-hospitality mortality was 5%, and anastomotic leakage rate was 14%. In 87% of patients, R0 resection was achieved. Overall, 4-year survival was 20%. A R0 resection, early-stage disease and 3-FD favored the survival advantage (P < 0.05. Conclusion: The mortality, complication, and survival results were in the acceptable range. R0 resection and radical nodal dissection should be standard practice.

    Verrucous squamous cell cancer (VSCC) of the esophagus is a variant of squamous cell carcinoma. This rare entity has been described in only a handful of case reports in the literature. We sought to evaluate the endoscopic features, treatment, and outcomes related to esophageal VSCC. The medical records of all patients with esophageal VSCC seen at our institution from January 1995 to December 2010 were reviewed retrospectively. A total of 11 patients (6 men; mean age 66 years [range 57-75 years]) were identified, with a mean follow up of 4 years (range 0.5-10 years) available in nine patients after diagnosis. About half the patients smoked or consumed alcohol on a regular basis. The median time interval from onset of symptoms to diagnosis of esophageal VSCC was 2.5 years (range 1-20 years), with dysphagia being present in all patients. The majority of tumors (8 of 11) exhibited a white, warty, plaque-like appearance with superimposed Candida at endoscopy, which led solely to a diagnosis of Candida esophagitis on initial presentation. The disease was either extensive (n = 5) throughout the esophagus or localized (n = 6) often by tumor nodules or projections, with the lower third of the esophagus being most commonly involved. Initial pinch biopsies were nondiagnostic in eight (73%) of the patients. Six patients underwent esophagectomy; neoadjuvant chemoradiation therapy was provided in two. In patients treated solely with surgery and who had a preoperative endoscopic ultrasound, the latter tended to overestimate staging of the lesion relative to surgical pathologic staging. Two patients were deemed to be poor operative candidates and received only chemoradiation treatment. One patient with a T2N0 tumor by endoscopic ultrasound staging was managed symptomatically with intermittent endoscopic dilation because of significant comorbidities that precluded surgery and oncologic therapy. There has been no evidence for residual or recurrent neoplastic disease in the eight

    Highlights: • Oral effervescent powder improves esophageal distension and wall assessment at CT. • This technique improves detection and T staging of esophageal cancer at CT. • It can be easily adopted in clinical routine in patients with esophageal pathology. - Abstract: Purpose: To assess the value of oral effervescent powder (EP) for evaluation of esophageal distension, and for detection and staging of esophageal cancer with contrast-enhanced CT. Materials and methods: 84 patients without esophageal pathology and 52 patients with histological confirmed diagnosis of esophageal cancer were included in this prospective IRB-approved study. Half of the patients in both groups received EP prior to CT. Esophageal distension was assessed by planimetry of the inner (IA) and outer area (OA). Two blinded readers evaluated the datasets separately with regard to diagnosis of esophageal cancer (yes/no) and staging (T0-T4), if applicable. Distension results were compared (t-Test). In patients with cancer sensitivity, specificity, NPV and PPV were calculated. CT staging results were compared to histopathology (Cohen-k). Results: IA and IA/OA were significantly larger after EP as compared to the group without EP (p < 0.05). Sensitivity, specificity, NPV and PPV for cancer detection cancer were as follows: 78%/78%, 98%/98%, 95%/95%, 87%/87% with EP; 60%/68%, 98%/98%, 94%/94%, 80%/83% without EP. Staging with EP was good (k = 0.84/0.67) and moderate without EP (k = 0.58/0.59). Conclusions: Administration of EP prior to CT results in good distension of the esophagus, and improves detection and staging of esophageal cancer, as compared to control studies without EP.

    Conclusions: The EM and the ITV margins in cT4 were significantly smaller than those in cT1-T3. The NM and the ITV margins of abdominal LNs were much larger than those of cervicothoracic LNs and the esophagus. In clinical radiation therapy planning for esophageal cancer, we should take cT stage into consideration.

    Full Text Available CONTEXT AND OBJECTIVESEsophageal cancer is the eighth commonest type of cancer worldwide, occupying sixth place in terms of mortality. Smoking and alcohol use are known risk factors for this type of cancer. The aim here was to evaluate the risk factors for esophageal cancer in a low-incidence area.DESIGN AND SETTINGCase-control study in Goiânia, with 99 cases of esophageal cancer and 223 controls.METHODSThe variables were sociodemographic, dietary, occupational and lifestyle data. The sample was analyzed using the chi-square test, Mann-Whitney test and Mantel-Haenszel approach for multivariate analysis. Odds ratios (OR were calculated with 5% significance and 95% confidence intervals.RESULTSThe risk of esophageal cancer was higher in patients ≥ 55 years (OR = 1.95; P < 0.001. Patients from rural areas were at greater risk of esophageal cancer (OR = 4.9; P < 0.001. Smoking was a risk factor among the cases (OR = 3.8; P < 0.001, as was exposure to woodstoves (OR = 4.42; P < 0.001. The practice of oral sex was not a risk factor (OR = 0.45; P = 0.04. Consumption of apples, pears, vegetables, cruciferous vegetables and fruit juices were protective against esophageal cancer.CONCLUSIONIn a region in which the incidence of esophageal cancer is low, the most significant risk factors were exposure to woodstoves, smoking and living in rural areas.

    We studied the clinical outcome of chemoradiotherapy for clinical Stage I squamous cell carcinoma of the esophagus. Seventy-one patients without possibility of cure by endoscopic mucosal resection (EMR) were analyzed. Patients received continuous infusion of 5FU at a dose of 700 mg/m{sup 2}/24 hours on days 1 to 4, combined with CDDP at a dose of 70 mg/m{sup 2} on day 1, and concurrent radiation therapy at a dose of 30 Gy in 15 fractions over 3 weeks. This schedule was repeated twice every 4 weeks, for a total radiation dose of 60 Gy. The 66 patients (93%) achieved a complete response. Toxicities were generally mild, but late radiation morbidity was relatively frequent. However, no toxicities interfering with function were seen. With a median follow-up duration of 23 months, the 1, 2 and 3-year survival rates were 97%, 90% and 80%, respectively. This survival rate compared with that obtained by ordinary surgery with three-field lymph node dissection. Chemoradiotherapy for clinical Stage I esophageal cancer is a promising method, because of its safety and its being a curative therapy. We should present this therapy as well as surgery as an option of possibly curative therapy to patients with clinical Stage I esophageal cancer. (author)

    Carcinoma of the esophagus is an aggressive and lethal malignancy with an increasing incidence world-wide.Incidence rates vary internationally,with the highest rates found in Southern and Eastern Africa and Eastern Asia,and the lowest in Western and Middle Africa and Central America.Patients with locally advanced disease face a poor prognosis,with 5-year survival rates ranging from 15%-34%.Recent clinical trials have evaluated different strategies for management of locoregional cancer; however,because of stage migration and changes in disease epidemiology,applying these trials to clinical practice has become a daunting task.We searched Medline and conference abstracts for randomized studies published in the last 3 decades.We restricted our search to articles published in English.Neoadjuvant chemoradiotherapy followed by surgical resection is an accepted standard of care in the United States.Esophagectomy remains an essential component of treatment and can lead to improved overall survival,especially when performed at high volume institutions.The role of adjuvant chemotherapy following curative resection is still unclear.External beam radiation therapy alone is considered palliative and is typically reserved for patients with a poor performance status.

    HpD photodynamic therapy (PDT) was performed on 4 patients with superficial esophageal cancer, 20 patients with 22 early gastric cancer lesions and one patient with advanced gastric cancer. About 50 h before irradiation, 3 mg/kg of HpD or 1.3-2.5 mg/kg of Photofrin II was injected intravenously. The entire lesion including a 5-mm border of normal surrounding mucosa, was irradiated with an argon dye laser at 630nm wavelength with an output of 100-400mW at the tip of the fiber. Complete response (CR) to HpD-PDT was obtained in 2 of 2 mucosal esophageal cancers, and one of 2 submucosal lesions, totalling 3 of 4, and in 13 of 13 mucosal gastric cancers and 7 of 9 submucosal lesions totalling 20 of 22. The depths of cancer involvement were determined endoscopically. In Borrmann 1 lesion with muscularis externa involvement, in spite of two trials with HpD-PDT, only partial response (PR) was obtained. Tumor laser dose had to be more than 90 J/cm2, and in several cases combined hot biopsy with electrodiathermy and/or repeated HpD-PDT was needed to obtain CR. HpD-PDT is indicated for superficial esophageal cancer and depressed and/or assembled protuberant-type of early gastric cancer with poor risk.

    From 1994 to 1995, to evaluate the utility of preoperative CT, EUS (endoscopic ultrasonography) and US in the diagnosis of lymph node metastasis in thoracic esophageal cancer, 94 patients with thoracic esophageal cancer who underwent esophagectomy were studied clinicopathologically. The sensitivity of EUS diagnosis of upper mediastinal lymph node metastasis (85%), left-sided paragastrin lymph node metastasis (73-77%), and especially lower paraesophageal lymph node metastasis (100%) were good. But due to their low-grade specificity in EUS diagnosis, their overall accuracy was not very good. On the other hand, the overall accuracy of the CT diagnosis of lymph node metastasis was fine. However, sensitivity, the most important clinical factor in the CT diagnosis of lymph node metastasis was considerably inferior to EUS. The assessment of the diagnosis of lymph node metastasis around the tracheal bifurcation and the pulmonary hilum and the left para-cardial lesion by CT or EUS was poor. It was concluded that lymph node metastasis of these area must be the pitfall in preoperative diagnosis. The average diameter of the lymph nodes and the proportion of cancerous tissue in the lymph nodes diagnosed as metastatic lymph nodes by CT was larger than that of the false negative lymph nodes. However, the lymph nodes diagnosed as true positives by EUS showed no such tendency. This must be the reason the sensitivity of the EUS diagnosis and specificity of the CT diagnosis were favorable, but the specificity of the EUS diagnosis and especially the sensitivity of the CT diagnosis were not as good.

    A retrospective study was performed to evaluate whether postoperative adjuvant radiotherapy can improve survival and decrease recurrence as compared with surgery alone in resected esophageal cancer. From Jan. 1985 to Dec. 1993, among 94 esophageal cancer patients treated with surgery, fifty-one patients were included in this study. Transthoracic esophagectomy was performed in 35 patients and transhiatal esophagectomy in 16. Postoperative adjuvant radiotherapy was performed 4 weeks after surgery in 26 among 38 patients in stage II and III. A total dose of 30 {approx} 60 Gy in 1.8 Gy daily fraction, median 54 Gy over 6 weeks, was delivered in the mediastinum + both supraclavicular lymph nodes or celiac lymph nodes according to the tumor location. Forty-seven patients (92%) had squamous histology. The median follow-up period was 38 months. The overall 2-year and 5-year survival and median survival were 56.4%, 36.8% and 45 months. Two-year and 5-year survival and median survival by stage were 92%, 60.3% for stage I, 63%, 42% and 51 months for stage II and 34%, 23% and 19 months for stage III ({rho} = 0.04). For stage II and III patients, 5-year survival and median survival were 22.8%. 45 months for the surgery alone group and 37.8%, 22 months for the postoperative RT group ({rho} = 0.89). For stage III patients, 2-year survival and median survival were 0%, 11 months for the surgery alone group and 36.5%, 20 months for the postoperative RT group ({rho} = 0.14). Local and distant failure rates for stage II and III were 50%, 16% for the surgery alone and 39%, 31% for the postoperative RT group. For N1 patients, local failure rate was 71% for the surgery alone group and 37% for the postoperative RT group ({rho} = 0.19). Among 10 local failures in the postoperative RT group, in-field failures were 2, marginal failures 1, out-field 5 and anastomotic site failures 2. There were no statistically significant differences in either the overall survival or the patterns of failure

    AIM: To evaluate the therapeutic effect of radiotherapy for esophageal cancer after expandable metallic stent placement.METHODS: Ten cases of advanced esophageal cancer were evaluated, 7 having complete obstruction and 3 with digestive-respiratory fistula. Ten nitinol stents were placed at the site of stenosis. Patients were treated with a total dose of 1 200 cGy divided into 3 fractions of 400 cGy 4-7 d after stents placement.RESULTS: All the 10 stents were placed successfully at one time. After radiotherapy for advanced esophageal cancer, the survival period of the cases ranged from 14 to 22 mo, with a mean survival of 17 mo. No re-stenosis occurred among all the 10 cases.CONCLUSION: Stent placement combined with radiotherapy for esophageal cancer is helpful to prolong patients' survival and reduce occurrence of re-stenosis.

    AIM: To characterize the tumor suppressor gene p53 mutations in exon 4, esophageal cancer and adjacent noncancerous tissues.METHODS: We performed p53 (exons 4-8) gene mutation analysis on 24 surgically resected human esophageal cancer specimens by PCR, single-strand conformation polymorphism, and DNA sequencing. RESULTS: p53 gene mutations were detected in 9 of 22 (40.9%) esophageal cancer specimens and 10 of 17 (58.8%) adjacent non-cancerous tissues. Eight of sixteen (50.0%) point mutations detected were G-A transitions and 9 of 18 (50.0%) p53 gene mutations occurred in exon 4 in esophageal cancer specimens. Only 1 of 11 mutations detected was G-A transition and 4 of 11 (36.4%) p53 gene mutations occurred in exon 4 in adjacent non-cancerous tissues.CONCLUSION: Mutation of p53 gene in exon 4 may play an important role in development of esophageal cancer. The observation of p53 gene mutation in adjacent noncancerous tissues suggests that p53 gene mutation may be an early event in esophageal carcinogenesis. Some clinical factors, including age, sex, pre-operation therapy and location of tumors, do not influence p53 gene mutation rates.

    Recently, endoscopic examinations have played a major role in the diagnosis and treatment in the field of gastroenterology. It is considered that endoscopy would be an important examination for cancer screening of the esophagus and the stomach. However, endoscopic services for cancer screening are in short supply. Furthermore, we have to take the complications and poor economic benefits of endoscopy in to consideration when we apply it as a practical cancer screening system. Thus, an effective primary screening system must be provided for the endoscopic screening of cancer of the esophagus and the stomach. People with a defect in aldehyde dehydrogenase-2(ALDH2)should be distinguished by their facial flushing in drinking and for their high risks of esophageal cancer. In cases with gastric cancer screening by endoscopy, an x-ray study is expected to be a primary screening because of its efficacy. It already has been recommended for population-based screening in Japanese guidelines for gastric cancer screening. In cases with opportunistic screening of gastric cancer, patients should be allowed to choose from several studies such as the x-ray study, direct endoscopy, and the so-called high risk screening of gastric cancer for estimating risks and planning of screening for gastric cancer.

    The objectives of this retrospective study were to elucidate the clinicopathological features and recent surgical results of cervical esophageal cancer. Cervical esophageal cancer has been reported to have a dismal prognosis. Accurate knowledge of the clinical characteristics of cervical esophageal cancer is warranted to establish appropriate therapeutic strategies. The clinicopathological features and treatment results of 63 consecutive patients with cervical esophageal cancer (Ce group) who underwent surgical resection from 1980 to 2013 were analyzed and compared with 977 patients with thoracic or abdominal esophageal cancer (T/A group) who underwent surgical resection during that time. Among the patients who received curative resection, the 5-year overall and disease-specific survival rates of the Ce patients were significantly better than those of the T/A patients (overall: 77.3% vs 46.5%, respectively, P = 0.0067; disease-specific: 81.9% vs 55.8%, respectively, P = 0.0135). Although total pharyngo-laryngo-esophagectomy procedures were less frequently performed in the recent period, the rate of curative surgical procedures was markedly higher in the recent period (2000-1013) than that in the early period (1980-1999) (44.4% vs 88.9%, P = 0.0001). The 5-year overall survival rate in the recent period (71.5%) was significantly better than that in the early period (40.7%, P = 0.0342). Curative resection for cervical esophageal cancer contributes to favorable outcomes compared with other esophageal cancers. Recent surgical results for cervical esophageal cancer have improved, and include an increased rate of curative resection and decreased rate of extensive surgery.

  15. Genetic polymorphisms of ADH2 and ALDH2 association with esophageal cancer risk in southwest China

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    AIM: To evaluate the impact of alcohol dehydrogenase 2 (ADH2) and aldehyde dehydrogenase 2 (ALDH2)polymorphisms on esophageal cancer risk.METHODS: One hundred and ninety-one esophageal cancer patients and 198 healthy controls from Yanting County were enrolled in this study. ADH2 and ALDH2genotypes were examined by polymerase-chain-reaction with the confronting-two-pair-primer (PCR-CTPP)method. Unconditional logistic regression was used to calculate the odds ratios (OR) and 95% confidence interval (95% CI).RESULTS: Both ,ADH2*1 allele and ,ALDH2*1/*2 allele showed an increased risk of developing esophageal cancer. The adjusted OR (95% CI) for ,ADH2*1allele compared with ,ADH2*2/*2 was 1.65 (95%CI= 1.02-2.68) and 1.67 (95% CI= 1.02-2.72) for ,ALDH2*1/*2 compared with ALDH2*1/*1. A significant interaction between ,ALDH2 and drinking was detected regarding esophageal cancer risk, the OR was 1.83(95% CI = 1.13-2.95). Furthermore, when compared with ADH2*2/*2 and ALDH2*1/*1 carriers, ADH2*1 and ALDH2*2 carriers showed an elevated risk of developing esophageal cancer among non-alcohol drinkers (OR =2.46, 95% CI= 0.98-6.14), and a significantly elevated risk of developing esophageal cancer among alcohol drinkers among alcohol drinkers (OR = 9.86, 95% CI=3.10-31.38).CONCLUSION: ADH2 and ALDH2 genotypes are associated with esophageal cancer risk. ADH2*1 allele and ALDH2*2 allele carriers have a much higher risk of developing esophageal cancer, especially among alcohol drinkers.

    We herein present the case of a 56-year-old Japanese woman who developed purulent pericarditis after undergoing chemoradiotherapy for esophageal cancer. She developed epigastralgia and a fever and was admitted to our hospital. A physical examination revealed hypotension, tachycardia and pericardial friction rub. Echocardiography revealed moderate pericardial effusion. Based on these observations, the patient was diagnosed with cardiac tamponade. Computed tomography confirmed the presence of an esophagopericardial fistula. Treatment with pericardiocentesis, drainage and short-term intrapericardial administration of antibiotics relieved the patient's symptoms. Daily rinsing through a catheter with normal saline prevented relapse of the purulent pericarditis. Esophagopericardial fistulas are so rare that their treatment is not well-established. We herein report successful palliative care of a malignant esophagopericardial fistula associated with purulent pericarditis.

    Esophageal cancer commonly has a poor prognosis, which requires an accurate diagnosis and early treatment to improve outcome. Other modalities for staging, such as endoscopic ultrasound imaging and computed tomography (CT) scans, have a role in diagnosis and staging. However, PET with fluorine-18 fluoro-2-deoxy-d-glucose/CT (FDG PET/CT) scanning allows for improved detection of distant metastatic disease and can help to prevent unnecessary interventions that would increase morbidity. FDG PET/CT scanning is valuable in the neoadjuvant chemotherapy assessment and predicting survival outcomes subsequent to surgery. FDG PET/CT scanning detects recurrent disease and metastases in follow-up. Copyright © 2017 Elsevier Inc. All rights reserved.

    Esophageal cancer is one of the most common malignancies of the gastrointestinal cancers and carries poorer prognosis than other gastrointestinal cancers. In general practice, the depth of tumor infiltration in esophageal wall is crucial to establishing appropriate treatment plan which is established by detecting the tumor infiltration depth. Connective tissue is one of the main structures that form the esophageal wall. So, identification of tumor cells infiltrating into connective tissue is helping for detecting the tumor infiltration depth. Our aim is to evaluate whether multiphoton microscopy (MPM) can be used to detect tumor cells infiltrating into connective tissue in the esophageal cancer. MPM is well-suited for real-time detecting morphologic and cellular changes in fresh tissues since many endogenous fluorophores of fresh tissues are excited through two-photon excited fluorescence (TPEF) and second harmonic generation (SHG). In this work, microstructure of tumor cells and connective tissue are first studied. Then, morphological changes of collagen fibers after the infiltration of tumor cells are shown. These results show that MPM has the ability to detect tumor cells infiltrating into connective tissue in the esophageal cancer. In the future, MPM may be a promising imaging technique for detecting tumor cells in esophageal cancer.

    Telomerase is mainly active in human tumor cells, which provides an opportunity for a therapeutic window on telomerase targeting. We sought to evaluate the potential of the thio-phosphoramidate oligonucleotide inhibitor of telomerase, imetelstat, as a drug candidate for treatment of esophageal cancer. Our results showed that imetelstat inhibited telomerase activity in a dose-dependent manner in esophageal cancer cells. After only 1 week of imetelstat treatment, a reduction of colony formation ability of esophageal cancer cells was observed. Furthermore, long-term treatment with imetelstat decreased cell growth of esophageal cancer cells with different kinetics regarding telomere lengths. Short-term imetelstat treatment also increased γ-H2AX and 53BP1 foci staining in the esophageal cancer cell lines indicating a possible induction of DNA double strand breaks (DSBs). We also found that pre-treatment with imetelstat led to increased number and size of 53BP1 foci after ionizing radiation. The increase of 53BP1 foci number was especially pronounced during the first 1h of repair whereas the increase of foci size was prominent later on. This study supports the potential of imetelstat as a therapeutic agent for the treatment of esophageal cancer.

    The Swedish Family-Cancer Database was used to analyze second cancers after oral, esophageal, rectal, cervical, genital and skin (squamous cell carcinoma) cancers. A strong and consistent association of second cancers was observed at all these sites, in men and women. As a novel finding, an association of rectal cancer with the human papillomavirus (HVP)-related cancers was shown. New evidence on an excess of skin cancer with the HPV-related cancers was also provided. As an epidemiological study, the associations were strong and often supported by a number of comparisons. These could not be explained by bias or long-term treatment related effects. However, whether the findings on rectal and skin cancer are due to HPV or other infections, transient or inherited depressed immune function or other constitutional factors remains to be established.

    Full Text Available Esophageal cancer is one of the most common malignancies in our country. Patients often seek medical advice in advanced and inoperable stages or with cervical esophageal cancer, in which operation is accompanied by sever morbidity. In this conditions many of them cannot tolerate chemo-radiation, or refuse it. Therefore radiotherapy is applied as a single modality in palliation of many patients with esophageal cancer. One of the palliative radio therapeutic methods is application of 5000 CGY in 20 fractions (Long Course; but considering the great number of our patients and limited capacity of radiotherapy centers, as well as emphasis of literature on palliation with 4000 CGY in 13 fractions (short course, we decided to compare these two methods (which are both used in our departments. In this retrospective analytic study, the files of 283 patients with esophageal cancer referred to cancer institute of Imam Khomeini Hospital from 1989-1999 were studied. Patients were between 27-97 years old (mean age=58.3 and most of them were male (53.7 percent. The mean length of lesion was 8.5 cm. The most common site of lesion was middle third at esophagus (48.1 percent and the most common pathology was squamous cell carcinoma (99.6 percent. Fifty-four percent of patients were hot tea drinkers habitually. From the mentioned variables, only length of lesion had significant relationship with overall survival (P=0.04. Thirty-eight of 283 patients were excluded from analytic study because of incomplete follow-up. The number of patients had been treated by long course (5000 CGY in 20 fractions was 137 and the remainder (108 patients by short course (4000 CGY in 13 fractions. No significant difference was seen statistically between these two groups in overall and dysphagia-free survival (Kaplan-Meyer test. Also total dosage of spinal cord is lower in the short course. Thus regarding to less required time in short course and comparable palliation and survival between

    Full Text Available Abstract Background Family history (FH by different relative types and risk of upper gastrointestinal (UGI cancers has been only rarely reported; the data on UGI cancer survival are sparse. Methods 600 esophageal squamous cell carcinoma (ESCC cases, 598 gastric cardia adenocarcinoma cases, and 316 gastric non-cardia adenocarcinoma cases, and 1514 age-, gender-, and neighborhood-matched controls were asked for FH in first degree relatives and non-blood relatives. Odds ratios (ORs and 95% confidence intervals (CIs from logistic regressions, and hazard ratios (HRs from Cox proportional hazard regressions were estimated. Results Increased ESCC risk was associated with FH of any cancer (OR = 1.72, 95% CI = 1.39–2.12, FH of any UGI cancer (OR = 2.28, 95%CI = 1.77–2.95 and FH of esophageal cancer (OR = 2.84, 95%CI = 2.09–3.86, but not FH of non-UGI cancer. Individuals with two or more affected first-degree relatives had 10-fold increased ESCC risk. FH of gastric cardia cancer was associated with an increased risk of all three cancers. Cancer in non-blood relatives was not associated with risk of any UGI cancer. FH of UGI cancer was associated with a poorer survival rate among younger ESCC cases (HR = 1.82, 95%CI = 1.01–3.29. Conclusion These data provide strong evidence that shared susceptibility is involved in esophageal carcinogenesis and also suggest a role in prognosis.

    AIM: To shed light on the possible role of mismatch repair gene Mlh3 in familial esophageal cancer (FEC).METHODS: A total of 66 members from 10 families suggestive of a genetic predisposition to hereditary esophageal cancer were screened for germline mutations in Mlh3 with denaturing high performance liquid chromatography (DHPLC), a newly developed method of comparative sequencing based on heteroduplex detection. For all samples exhibiting abnormal DHPLC profiles,sequence changes were evaluated by cycle sequencing.For any mutation in family members, we conducted a segregation study to compare its prevalence in sporadic esophageal cancer patients and normal controls.RESULTS: Exons of Mlh3 in all samples were successfully examined. Overall, 4 missense mutations and 3 polymorphisms were identified in 4 families. Mlh3 missense mutations in families 9 and 10 might be pathogenic, but had a reduced penetrance. While in families 1 and 7,there was no sufficient evidence supporting the monogenic explanations of esophageal cancers in families.The mutations were found in 33% of high-risk families and 50% of low-risk families.CONCLUSION: Mlh3 is a high risk gene with a reduced penetrance in some families. However, it acts as a low risk gene for esophageal cancer in most families. Mutations of Mlh3 may work together with other genes in an accumulated manner and result in an increased risk of esophageal tumor. DHPLC is a robust and sensitive technique for screening gene mutations.

    Esophageal cancer is the sixth most common cause of cancer-related death worldwide. Current chemotherapy regimens include a combination of 5-fluorouracil (5-FU) and cisplatin, but more efficient therapy strategies are needed to increase 5-year survival. Alterations in the signaling pathway of the tumor suppressor gene Rb-1, which encodes a phosphoprotein (pRB) that negatively regulates the G1/S transition of the cell cycle, are present in 70% of all tumors, but its role in esophageal cancer is still unclear. Most of these are alterations leading to up-regulation of the activity of cyclin-dependent kinases (CDKs) to phosphorylate pRB, which suggests that keeping the wild type pRB phosphorylated might be advantageous. Besides proliferation, pRB also regulates apoptosis induced by tumor necrosis factor-alpha (TNF-α) and DNA-damage. We investigated the status of phosphorylation of pRB along esophageal tumorigenesis stages, as well as whether hyperphosphorylation of pRB could suppress apoptosis induced by cisplatin, 5-FU, or TNF-α in esophageal cancer cells. pRB phosphorylation increased progressively from normal esophageal tissue to metaplasia and adenocarcinoma, suggesting that pRB phosphorylation increases along esophageal tumor stages. When RB-1 was knocked down or CDK inhibitors reduced the levels of phosphorylated pRB, opposite apoptotic effects were observed, depending on the combination of drugs tested: whereas TNF-α- and cisplatin-induced apoptosis increased, 5-FU-induced apoptosis decreased. Taken together, these data suggest that pRB plays a role in esophageal adenocarcinoma and that, depending on the type of anti-cancer treatment, combining CDK inhibitors and chemotherapy has the potential to increase the sensitivity of esophageal cancer cells to cell death.

    Esophageal cancer is a neoplasm with a poor prognosis. Its two histologic subtypes, esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC), have been associated with different risk factors. The possibility of an association between the consumption of hot food and beverages and esophageal cancer, especially ESCC, has long been suspected, presenting a potentially modifiable risk factor. A meta-analysis of existing observational studies was performed to provide a quantitative estimate of the risk of esophageal cancer associated with the consumption of hot food and drink. A search was conducted through MEDLINE, PubMed, EMBASE, and Current Contents Connect to November 11, 2014. Pooled ORs and 95% CIs were calculated using a random effects model for the risk of esophageal cancer associated with the consumption of hot food and drink. Subgroup analyses were conducted for ESCC and EAC, as well as for studies that adjusted for tobacco smoking and alcohol consumption, two well-recognized risk factors for ESCC. Consumption of hot food and drink was associated with an increased risk of any esophageal cancer (OR=1.90, 95% CI=1.46, 2.48). Heterogeneity was observed. There was an increased risk of ESCC (OR=2.29, 95% CI=1.79, 2.93), which remained even after adjusting for significant confounding variables (OR=2.39, 95% CI=1.71, 3.33). The relationship was not significant for EAC. The consumption of hot food and beverages was associated with an increased risk of esophageal cancer, particularly ESCC. Crown Copyright © 2015.

    Objective:To investigate the relationship between p53 protein overexpression in esophageal and cervical squamous cell cancer and their clinical radiosensitivity. Methods: The immuno-histochemical assays were done for 52 cases with esophageal and cervical squamous cell cancer. The relationship between the assay results and short-term radiotherapy was investigated. Results: p53 overer-pression was 52.38% and 35. 48% respectively, in esophageal cancer and cervical cancer;p53 over-expression in high differentiated squamous cell cancer was knver than these in moderate and poor differentiated cases(P0. 05). In the cases of cervical cancer, p53 overexpression had the less short-term effect(P0. 05).Conclusion:This study suggests that p53 gene has the certain relationship with tumor radiosensitivity.

    The existence of other primary tumors during the treatment of esophageal cancer patients has been an important issue. Our aim is to investigate the prevalence and management of colorectal neoplasia (CRN) in surgically treated esophageal cancer patients. Between 2002 and 2008, 93 patients with esophageal cancer were surgically treated. Seventy-three patients underwent subtotal esophagectomy and 20 underwent lower esophagectomy for esophageal cancer. Colonoscopy was available for detecting CRN before and after surgery. Eighty-nine (95.7%) of the 93 patients were screened by colonoscopy preoperatively or within a year from the operation. Thirty-nine patients (43.8%) with CRN were synchronously identified: adenoma in 34 (38.2%) and adenocarcinoma in 5 patients (5.6%). Eleven adenomas with high grade-dysplasia and 8 adenomas with low grade-dysplasia were removed endoscopically. Three superficial adenocarcinomas were endoscopically removed before surgery, and 2 adenocarcinomas were surgically removed. Seventy-four patients (83.1%) were followed using colonoscopy, and 11 subsequent CRN, including 2 superficial adenocarcinomas, were endoscopically detected in 8 patients (10.8%). The size of esophageal cancer was larger in the patients with than without CRN (p = 0.036). The body mass index in esophageal cancer patients with CRN tended to be higher than in those without CRN (p = 0.065). We noted that esophageal cancer is frequently associated with synchronous and/or metachronous colorectal cancer and adenomas. Colonoscopy is useful to detect and manage CRN before and after esophagectomy, although a few limitations exist. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd.

    OBJECTIVE To characterize the histologic types of esophageal cardiac mucosa by endoscopic survey in a high-risk cancer area of China. METHODS An endoscopic survey with Lugol,s staining was carried out in Cixian County, Hebei Province from December 2001 to May 2002. The data were processed using computer SPSS 10.0 software. RESULTS The incidences of mild esophagitis, moderate esophagitis, and severe esophagitis were for 2013 cases, 34.9%(703), 1.6%(33) and 0.1% (2)respectively; those with mild dysplasia, moderate dysplasia, severe dysplasia of the esophagus were 8.6% (172), 7.8% (157) and 2.6% (53) respectively; those with carcinoma in situ, intramucosal carcinoma, invasive squamous carcinoma of the esophagus were 2.5%(50), 0.2% (4) and 0.7%(14) respectively. The histologic-detecting rates of non-atrophic gastritis, and atrophic gastritis of the cardia were 36.3%(730), 11.5% (232) respectively; those with mild dysplasia, severe dysplasia of the cardia were 2.5%(51), 0.8%(17) respectively; those with intramucosal adenocarcinoma, invasive adenocarcinoma of the cardia were 0.1% (3), 0.8%(17) respectively. The early-detection rate of esophageal cancer was 79.4%(54/68). The survey rate(examined population to covered population) was 73.8% (2013/2725). CONCLUSIONS Esophageal endoscopic screening with Lugol's solution staining has an advantage over esophageal balloon cytology, in that the histological diagnoses of esophageal cardiac diseases can be obtained, thus contributing to the prevention of subsequent disease. In using the staining method the detection rate of early esophageal cancer is higher than that revealed by balloon cytology.

    Magnetic stent hyperthermia (MSH) is a novel approach for targeted thermotherapy for esophageal cancer, which is based on the mechanism that inductive heat can be generated by the esophageal stent upon exposure under an alternative magnetic field (AMF). A positive effect of MSH on esophageal cancer has been demonstrated, however, there is no study on the in vitro effects of heating treatment or of the effects of AMF exposure on human esophageal cancer cells. This study aimed to investigate the effect of MSH and of AMF exposure in esophageal cancer cells. Inductive heating characteristics of esophageal stents were assessed by exposing the stents under AMF. A rather rapid temperature rise of the Ni-Ti stent when subjected to AMF exposure was observed and the desired hyperthermic temperature could be controlled by adjusting the field parameter of the AMF. Human esophageal squamous carcinoma (ESCC) ECA-109 cells were divided into four groups: the control group, the water-bath heating group, the MSH group and the AMF exposure group. Hyperthermic temperatures were 43, 48 and 53˚C and the treatment time was in the range of 5-30 min. The MTT assay, apoptotic analysis and TUNEL staining were applied in the current investigation. Exposure of ECA-109 cells under AMF with a field intensity of 50 to 110 kA/m had negligible effect on cell viability, cell necrosis and apoptosis. Hyperthermia had a remarkable inhibitory effect on the cell viability and the effect was dependent on the thermal dose (temperature and time). The optimal thermal dose of MSH for ECA-109 cells was 48˚C for 20-30 min. The study also elucidated that there was a difference in the effects on cell necrosis and apoptosis between the heating mode of water bath and MSH. The data suggest that MSH may have clinical significance for esophageal cancer treatment.

    Full Text Available Abstract Background β-catenin is a multifunctional protein involved in two apparently independent processes: cell-cell adhesion and signal transduction. β-catenin is involved in Wnt signaling pathway that regulates cellular differentiation and proliferation. In this study, we investigated the expression pattern of β-catenin and cyclin D1 using immunohistochemistry and searched for mutations in exon 3 of the β-catenin gene and Axin gene in esophageal squamous cell carcinoma. Materials and methods Samples were obtained from 50 esophageal cancer patients. Immunohistochemical staining for β-catenin and cyclin D1 was done. Mutational analyses of the exon3 of the β-catenin gene and Axin gene were performed on tumors with nuclear β-catenin expression. Results Four (8% esophageal cancer tissues showed high nuclear β-catenin staining. Overexpression of cyclin D1 was observed in 27 out of 50 (54% patients. All four cases that showed nuclear β-catenin staining overexpressed cyclin D1. No relationship was observed between the expression pattern of β-catenin and cyclin D1 and age, sex, tumor size, stage, differentiation grade, lymph node metastasis, response to chemotherapy, or survival. No mutational change was found in β-catenin exon 3 in the four cases with nuclear β-catenin staining. Sequencing analysis of the Axin cDNA revealed only a splicing variant (108 bp deletion, position 2302–2409 which was present in the paired normal mucosa. Conclusion A fraction of esophageal squamous cell carcinomas have abnormal nuclear accumulation of β-catenin accompanied with increased cyclin D1 expression. Mutations in β-catenin or axin genes are not responsible for this abnormal localization of β-catenin.

    AIM: To estimate the incidence of esophageal cancer(EC) in Kilimanjaro in comparison to other regions in Tanzania. METHODS: We also examined the clinical, epidemiologic, and geographic distribution of the 1332 EC patients diagnosed and/or treated at Ocean Road Cancer Institute(ORCI) during the period 2006-2013. Medical records were used to abstract patient information on age, sex, residence, smoking status, alcohol consumption, tumor site, histopathologic type of tumor, date and place of diagnosis, and type and date of treatment at ORCI. Regional variation of EC patients was investigated at the level of the 26 administrative regions of Tanzania. Total, age- and sex-specific incidence rates were calculated. RESULTS: Male patients 55 years and older had higher incidence of EC than female and younger patients. Of histopathologically-confirmed cases, squamous-cell carcinoma represented 90.9% of histopathologic types of tumors. The administrative regions in the central andeastern parts of Tanzania had higher incidence rates than western regions, specifically administrative regions of Kilimanjaro, Dar es Salaam, and Tanga had the highest rates. CONCLUSION: Further research should focus on investigating possible etiologic factors for EC in regions with high incidence in Tanzania.

    Cronkhite-Canada Syndrome (CCS) is a rare non-inherited gastrointestinal polyposis syndrome with characteristic ectodermal changes. We report an extremely unusual case of CCS associated with primary esophageal and gastric cancers. A 74-year-old Japanese man with symptoms of anorexia and diarrhea was found to have primary esophageal and gastric cancers, as well as multiple gastric and colonic polyps. Based on the physical findings of onychodystrophy and alopecia, we diagnosed CCS. Because of his age and nutritional status, we decided to perform total gastrectomy for gastric cancer and chemoradiotherapy for esophageal cancer, upon completion of which the patient was started on steroid therapy for the CCS. After 1 week of steroid therapy, the patient's watery diarrhea improved. We recommend that for patients with CCS, the therapeutic strategy be carefully considered based on the patient's nutritional status, the severity of the CCS, and the extent of gastrointestinal cancer.

    To investigate the treatment outcome and failure patterns after definitive chemoradiation therapy in locally advanced, unresectable esophageal cancer. Materials and Methods: From February 1994 to December 2002, 168 patients with locally advanced unresectable or medically inoperable esophageal cancer were treated by definitive chemoradiation therapy. External beam radiation therapy (EBRT) (42-46 Gy) was delivered to the region encompassing the primary tumor and involved lymph nodes, while the supraclavicular fossa and celiac area were included in the treatment area as a function of disease location. The administered cone-down radiation dose to the gross tumor went up to 54-66 Gy, while the fraction size of the EBRT was 1.8-2.0 Gy/fraction qd or 1.2 Gy/fraction bid. An optional high dose rate (HDR) intraluminal brachytherapy (BT) boost was also administered (Ir-192, 9-12 Gy/3 -4 fx). Two cycles of concurrent FP chemotherapy (5-FU 1,000 mg/m2/day, days 2-6, 30-34, cisplatin 60 mg/m2/day, days 1, 29) were delivered during radiotherapy with the addition of two more cycles. Results: One hundred sixty patients were analyzable for this review [median follow-up time: 10 months (range 1-149 months)]. The number of patients within AJCC stages I, II, III, and IV was 5 (3.1%), 38 (23.8%), 68 (42.5%), and 49 (30.6%), respectively. A HDR intraluminal BT was performed in 26 patients. The 160 patients had a median EBRT radiation dose of 59.4 Gy (range 44.4-66) and a total radiation dose, including BT, of 60 Gy (range 44.4-72), while 144 patients received a dose higher than 40 Gy. Despite the treatment, the disease recurrence rate was 101/160 (63.1%). Of these, the patterns of recurrence were local in 20 patients (12.5%), persistent disease and local progression in 61 (38.1%), distant metastasis in 15 (9.4%), and concomitant local and distant failure in 5 (3.1%). The overall survival rate was 31.8% at 2 years and 14.2% at 5 years (median 11.1 months). Disease-free survival was 29

    AIM: To evaluate the impact of alcohol dehydrogenase-2 (ADH2) and aldehyde dehydrogenase-2 (ALDH2) polymorphisms on esophageal cancer susceptibility in Southeast Chinese males. METHODS: Two hundred and twenty-one esophageal cancer patients and 191 healthy controls from Taixing city in Jiangsu Province were enrolled in this study. ADH2 and ALDH2 genotypes were examined by polymerase chain reaction and denaturing highperformance liquid chromatography. Unconditional logistic regression was used to calculate the odds ratios (OR) and 95% confidence interval (CI). RESULTS: The ADH G allele carriers were more susceptible to esophageal cancer, but no association was found between ADH2 genotypes and risk of esophageal cancer when disregarding alcohol drinking status. Regardless of ADH2 genotype, ALDH2G/A or A/A carriers had significantly increased risk of developing esophageal cancer, with homozygous individuals showing higher esophageal cancer risk than those who were heterozygous. A significant interaction between ALDH2 and drinking was detected regarding esophageal cancer risk; the OR was 3.05 (95% CI: 1.49-6.25). Compared with non-drinkers carrying both ALDH2 G/G and ADH2 A/A, drinkers carrying both ALDH2 A allele and ADH2 G allele showed a significantly higher risk of developing esophageal cancer (OR = 8.36, 95% CI: 2.98-23.46).CONCLUSION: Both ADH2 G allele and ALDH2 A allele significantly increase the risk of esophageal cancer development in Southeast Chinese males. ALDH2 A allele significantly increases the risk of esophageal cancer development especially in alcohol drinkers. Alcohol drinkers carrying both ADH2 G allele and ALDH2 A allele have a higher risk of developing esophageal cancer.

    Purpose: We investigated clinical and treatment-related factors as predictors of symptomatic pericardial effusion in esophageal cancer patients after concurrent chemoradiation therapy. Methods and Materials: We reviewed 214 consecutive primary esophageal cancer patients treated with concurrent chemoradiation therapy between 2001 and 2010 in our institute. Pericardial effusion was detected on follow-up computed tomography. Symptomatic effusion was defined as effusion ≥grade 3 according to Common Terminology Criteria for Adverse Events v4.0 criteria. Percent volume irradiated with 5 to 65 Gy (V5-V65) and mean dose to the pericardium were evaluated employing dose-volume histograms. To evaluate dosimetry for patients treated with two-dimensional planning in the earlier period (2001-2005), computed tomography data at diagnosis were transferred to a treatment planning system to reconstruct three-dimensional plans without modification. Optimal dosimetric thresholds for symptomatic pericardial effusion were calculated by receiver operating characteristic curves. Associating clinical and treatment-related risk factors for symptomatic pericardial effusion were detected by univariate and multivariate analyses. Results: The median follow-up was 29 (range, 6-121) months for eligible 167 patients. Symptomatic pericardial effusion was observed in 14 (8.4%) patients. Dosimetric analyses revealed average values of V30 to V45 for the pericardium and mean pericardial doses were significantly higher in patients with symptomatic pericardial effusion than in those with asymptomatic pericardial effusion (P<.05). Pericardial V5 to V55 and mean pericardial doses were significantly higher in patients with symptomatic pericardial effusion than in those without pericardial effusion (P<.001). Mean pericardial doses of 36.5 Gy and V45 of 58% were selected as optimal cutoff values for predicting symptomatic pericardial effusion. Multivariate analysis identified mean pericardial dose as the

    This study aimed to investigate the contribution of fruit and family history to esophageal cancer, among residents with abnormal esophagus discovered in screening. The study was a frequency-matched case-control design in groups of normal esophagus, abnormal esophagus but not carcinoma, and esophageal squamous cell carcinoma. Odds ratio (OR) was estimated by unconditional logistic regression. Fruit intake (OR = 0.19, 95% CI = 0.06-0.56) and positive family history of esophageal cancer (OR = 3.87, 95% CI = 1.41-10.63) were associated with esophageal cancer compared to individuals with abnormal conditions of the esophagus. In individuals who consumed fruits at least once per week, the OR for family cancer history is reduced to a nonsignificant level (OR = 1.06, 95% CI = 0.07-15.91). In the individuals with abnormal esophagus at screening, fruit intake was possibly protective against esophageal cancer, even in the ones with positive family history. Local public health strategies should focus on the improvement in fruit intake.

    Flavonoids have been suggested to play a chemopreventive role in carcinogenesis. However, the epidemiologic studies assessing dietary intake of flavonoids and esophageal cancer risk have yielded inconsistent results. This study was designed to examine the association between flavonoids, each flavonoid subclass, and the risk of esophageal cancer with a meta-analysis approach. We searched for all relevant studies with a prospective cohort or case-control study design published from January 1990 to April 2016, using PUBMED, EMBASE, and Web of Science. Pooled odds ratios (ORs) were calculated using fixed or random-effect models. In total, seven articles including 2629 cases and 481,193 non-cases were selected for the meta-analysis. Comparing the highest-intake patients with the lowest-intake patients for total flavonoids and for each flavonoid subclass, we found that anthocyanidins (OR = 0.60, 95% CI: 0.49-0.74), flavanones (OR = 0.65, 95% CI: 0.49-0.86), and flavones (OR = 0.78, 95% CI 0.64-0.95) were inversely associated with the risk of esophageal cancer. However, total flavonoids showed marginal association with esophageal cancer risk (OR = 0.78, 95% CI: 0.59-1.04). In conclusion, our study suggested that dietary intake of total flavonoids, anthocyanidins, flavanones, and flavones might reduce the risk of esophageal cancer.

    To explore the function of the default mode network (DMN) in the psychopathological mechanisms of theory of mind deficits in patients with an esophageal cancer concomitant with depression in resting the state. Twenty-five cases of esophageal cancer with theory of mind deficits (test group) that meet the diagnostic criteria of esophageal cancer and neuropsychological tests, including Beck depression inventory, reading the mind in the eyes, and Faux pas, were included, Another 25 cases of esophageal cancer patients but without theory of mind deficits (control group) were enrolled. Each patient completed a resting-state functional magnetic resonance imaging. The functional connectivity intensities within the cerebral regions in the DMN of all the enrolled patients were analyzed. The results of each group were compared. The functional connectivity of the bilateral prefrontal central region with the precuneus, bilateral posterior cingulate gyrus and bilateral ventral anterior cingulate gyrus in the patients of the test group were all reduced significantly (P theory of mind deficits. The theory of mind deficits might have an important function in the pathogenesis of esophageal cancer.

    We searched for cases of perforation of the gastric tube after esophagectomy for esophageal cancer by reviewing the literature. Only 13 cases were found in the English literature, and serious complications were seen in all cases, especially in cases of posterior mediastinal reconstruction. However, in the Japanese literature serious complications were also frequently seen in retrosternal reconstruction. Gastric tubes are at a higher risk of developing an ulcer than the normal stomach, including an ulcer due to Helicobacter pylori infection, insufficient blood supply, gastric stasis, and bile juice regurgitation. H. pylori eradication and acid-suppressive medications are important preventive therapies for ordinary gastric ulcers, but for gastric tube ulcers the effects of such treatments are still controversial. We tried to determine the most appropriate treatment to avoid serious complications in the gastric tubes, but we could not confirm an optimal route because each had advantages and disadvantages. However, at least in cases with severe atrophic gastritis due to H. pylori infection or a history of frequent peptic ulcer treatment, the antesternal route is clearly the best. Many cases of gastric tube ulcers involve no pain, and vagotomy may be one of the reasons for this absence of pain. Therefore, periodic endoscopic examination may be necessary to rule out the presence of an ulcer.

    In the current study, we examined the protective effect of hydroferrate fluid MRN-100 against the carcinogen methylnitronitrosoguanidine (MNNG)-induced gastric and esophageal cancer in rats. MRN-100 is an iron-based compound composed of bivalent and trivalent ferrates. At 33 weeks post treatment with MNNG, rats were killed and examined for the histopathology of esophagus and stomach; liver, spleen, and total body weight; and antioxidant levels in the blood and stomach tissues. Results showed that 17/20 (85%) gastroesophageal tissues from carcinogen MNNG-treated rats developed dysplasia and cancer, as compared to 8/20 (40%) rats treated with MNNG plus MRN-100. In addition, MRN-100 exerted an antioxidant effect in both the blood and stomach tissues by increasing levels of GSH, antioxidant enzymes SOD, CAT, and GPx, and total antioxidant capacity (TAC) level. This was accompanied by a reduction in the total free-radical and malondialdehyde levels. Furthermore, MRN-100 protected against body and organ weight loss. Thus, MRN-100 exhibited significant cancer chemopreventive activity by protecting tissues against oxidative damage in rats, which may suggest its effectiveness as an adjuvant for the treatment of gastric/esophageal carcinoma.

    AIM: To study the mechanisms responsible for inactivation of a novel esophageal cancer related gene 4 (ECRG4) in esophageal squamous cell carcinoma (ESCC). METHODS: A pair of primers was designed to amplify a 220 bp fragment, which contains 16 CpG sites in the core promoter region of the ECRG 4 gene. PCR products of bisulfite-modified CpG islands were analyzed by denaturing high-performance liquid chromatography (DHPLC), which were confirmed by DNA sequencing. The methylation status of ECRG 4 promoter in 20 cases of esophageal cancer and the adjacent normal tissues, 5 human tumor cell lines (esophageal cancer cell line-NEC, EC109, EC9706; gastric cancer cell line- GLC; human embryo kidney cell line-Hek293)and 2 normal esophagus tissues were detected. The expression level of the ECRG 4 gene in these samples was examined by RT-PCR. RESULTS: The expression level of ECRG 4 gene was varied.Of 20 esophageal cancer tissues, nine were unexpressed,six were lowly expressed and five were highly expressed compared with the adjacent tissues and the 2 normal esophageal epithelia. In addition, 4 out of the 5 human cell lines were also unexpressed. A high frequency of methylation was revealed in 12 (8 unexpressed and 4 lowly expressed)of the 15 (80%) downregulated cancer tissues and 3 of the 4 unexpressed cell lines. No methylation peak was observed in the two highly expressed normal esophageal epithelia and the methylation frequency was low (3/20) among the 20 cases in the highly expressed adjacent tissues. The methylation status of the samples was consistent with the result of DNA sequencing. CONCLUSION: These results indicate that the inactivation of ECRG 4gene by hypermethylation is a frequent molecular event in ESCC and may be involved in the carcinogenesis of this cancer.

    Full Text Available BACKGROUND AND PURPOSE: Tissue microRNAs (miRNAs can detect cancers and predict prognosis. Several recent studies reported that tissue, plasma, and saliva miRNAs share similar expression profiles. In this study, we investigated the discriminatory power of salivary miRNAs (including whole saliva and saliva supernatant for detection of esophageal cancer. MATERIALS AND METHODS: By Agilent microarray, six deregulated miRNAs from whole saliva samples from seven patients with esophageal cancer and three healthy controls were selected. The six selected miRNAs were subjected to validation of their expression levels by RT-qPCR using both whole saliva and saliva supernatant samples from an independent set of 39 patients with esophageal cancer and 19 healthy controls. RESULTS: Six miRNAs (miR-10b*, miR-144, miR-21, miR-451, miR-486-5p, and miR-634 were identified as targets by Agilent microarray. After validation by RT-qPCR, miR-10b*, miR-144, and miR-451 in whole saliva and miR-10b*, miR-144, miR-21, and miR-451 in saliva supernatant were significantly upregulated in patients, with sensitivities of 89.7, 92.3, 84.6, 79.5, 43.6, 89.7, and 51.3% and specificities of 57.9, 47.4, 57.9%, 57.9, 89.5, 47.4, and 84.2%, respectively. CONCLUSIONS: We found distinctive miRNAs for esophageal cancer in both whole saliva and saliva supernatant. These miRNAs possess discriminatory power for detection of esophageal cancer. Because saliva collection is noninvasive and convenient, salivary miRNAs show great promise as biomarkers for detection of esophageal cancer in areas at high risk.

    In 2005, a program named “Early Detection and Early Treatment of Esophageal and Cardiac Cancer”(EDETEC) was initiated in China. A total of 8279 residents aged 40-69 years old were recruited into the EDETEC program in Linzhou of Henan Province between 2005 and 2008. Howerer, the cost-benefit of the EDETEC program is not very clear yet. We conducted herein a cost-benefit analysis of screening for esophageal and cardiac cancer. The assessed costs of the EDETEC program included screening costs for each subject, as well as direct and indirect treatment costs for esophageal and cardiac severe dyspiasia and cancer detected by screening. The assessed benefits of this program included the saved treatment costs, both direct and indirect, on esophageal and cardiac cancer, as well as the value of prolonged life due to screening, as determined by the human capital approach. The results showed the screening cost of finding esophageal and cardiac severe dysplasia or cancer ranged from ¥2707 to ¥4512, and the total cost on screening and treatment was ¥13 115-¥14 920. The cost benefit was ¥58 944-¥155 110 (the saved treatment cost, ¥17 730, plus the value of prolonged life,¥41 214-¥137 380). The ratio of benefit-to-cost (BCR) was 3.95-11.83. Our results suggest that EDETEC has a high benefit-to-cost ratio in China and could be instituted into high risk areas of China.

    The standard treatment of locally advanced type of mid-esophageal cancer is concurrent chemoradiation therapy (CRT). We evaluated the feasibility of chemotherapy with adding docetaxel to the classical basic regimens of cisplatin plus 5-fluorouracil (5-FU) and radiotherapy up to 70.2 Gy using dose escalations for esophageal cancer. It was possible to escalate radiation treatment dose up to 70.2 Gy by the respiratory-gated intensity- modulated radiotherapy (gated-IMRT) based on the 4DCT-simulation, with improving target coverage and normal tissue (ex., lung, heart, and spinal cord) sparing. This study suggested that the definitive chemo-radiotherapy with docetaxel, cisplatin, and 5-fluorouracil (i.e., DCF-R) and gating IMRT is tolerable and active in patients with locally advanced mid-esophageal cancer (AEC)

    To confirm the expression of molecular genetic alterations of p53, pRb, p16 in esophageal cancer and to investigate the expression of p53, pRb, p16 in esophageal cancer according to the pathologic steps of carcinogenesis, immuno-histochemistry was performed in 15 resected esophageal cancer specimens with multiple separated lesions after pathologic mapping. The accumulation of mutant p53 was observed in 60 % of dysplasia and 47 % of invasive cancer, while pRb was not detected in 91 % of dysplasia and 72.7 % of invasive cancer. But p16 was not observed in 0 % in dysplasia and 7 % of invasive cancer. But p16 was not observed in 0 % in dysplasia and 28.6 % in invasive cancer. There was no simultaneous negative pRb and p16 expression. There was no relations between p53 and p16, pRb. As a results, the expression of p53, pRb, p16 was co-related well with molecular genetic changes and inactivation of p53, pRb, p16 was co-related well with molecular genetic changes and inactivation of p53 and pRb was common and early event in esophageal carcinogenesis in Korea, but inactivation of p16 was a infrequent change.

    Full Text Available Background: World-wide, esophageal cancer is a growing epidemic and patients frequently present with advanced disease that is surgically inoperable. Hence, chemotherapy is the predominate treatment. Cytotoxic platinum compounds are mostly used, but their efficacy is only moderate. Newer alkylating agents have shown promise in other tumor types, but little is known about their utility in esophageal cancer. Methods: We utilized archived human esophageal cancer samples and esophageal cancer cell lines to evaluate O-6-methylguanine-deoxyribonucleic acid methyltransferase (MGMT hypermethylation status and determined sensitivity to the alkylating drug temozolomide (TMZ. Immunoblot analysis was performed to determine MGMT protein expression in cell lines. To assess and confirm the effect of TMZ treatment in a methylated esophageal cancer cell line in vivo, a mouse flank xenograft tumor model was utilized. Results: Nearly 71% (12/17 of adenocarcinoma and 38% (3/8 of squamous cell carcinoma (SCC patient samples were MGMT hypermethylated. Out of four adenocarcinoma and nine SCC cell lines tested, one of each histology was hypermethylated. Immunoblot analyses confirmed that hypermethylated cell lines did not express the MGMT protein. In vitro cell viability assays showed the methylated Kyse-140 and FLO cells to be sensitive to TMZ at an IC 50 of 52-420 μM, whereas unmethylated cells Kyse-410 and SKGT-4 did not respond. In an in vivo xenograft tumor model with Kyse-140 cells, which are MGMT hypermethylated, TMZ treatment abrogated tumor growth by more than 60%. Conclusion: MGMT methylation may be an important biomarker in subsets of esophageal cancers and targeting by TMZ may be utilized to successfully treat these patients.

    The incidence of Barrett’s esophageal cancer is one of the most rapidly increasing among all cancers in the West, and it is also expected to increase in Japan. The optimal treatment for early Barrett’s esophageal cancer remains controversial. En bloc esophagectomy with regional lymph node dissection has been considered the standard therapy. Endoscopic therapies are currently being evaluated as alternatives to esophagectomy because they can provide the least postoperative morbidity and the best quality of life. Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) allow for removal of visible lesions and histopathologic review of resected tissue, which help in diagnostic staging of the disease. EMR is limited with respect to resection size, and large lesions must be resected in several fragments. Piecemeal resection of lesions is associated with high local recurrence rates, probably because of minor remnants of neoplastic tissue being left in situ. ESD provides larger specimens than does EMR in patients with early Barrett’s neoplasia. This in turn allows for more precise histological analysis and higher en bloc and curative resection rates, potentially reducing the incidence of recurrence. Detailed endoscopic examination to determine the invasion depth and spread of Barrett’s esophageal cancer is essential before ESD. The initial inspection is usually conducted with white-light imaging followed by narrow-band imaging. The ESD procedure is similar to that for lesions in other parts of the gastrointestinal tract. However, the narrow space of the esophagogastric junction and contraction of the lower esophageal sphincter sometimes disturb the visual field and endoscopic control. Skilled endoscope handling, sometimes including retroflexion, is required during ESD for Barrett’s esophageal cancer. Previous reports have shown that ESD achieves en bloc resection in >80% of lesions. Although promising short-term results are reported, a long

    Esophageal cancer is associated with a poor prognosis with 5-year survival rates of approximately 15% to 20%. Although patients with early stage disease may adequately be treated with a single modality, combined therapy typically consisting of neoadjuvant chemoradiation followed by esophagectomy is being adopted increasingly in patients with locally advanced disease. In patients who are not surgical candidates, definitive chemoradiation is the preferred treatment approach. All patients with newly diagnosed esophageal cancer should be evaluated in the multidisciplinary setting by a surgeon, radiation oncologist, and medical oncologist owing to the importance of each specialty in the management of these patients.

    Esophageal cancer patients often present a highly inflamed esophagus at the time of treatment by photodynamic therapy. Immediately after treatment, the inflamed vessels have been shut down and the esophagus presents a white surface. Optoacoustic imaging via an optical fiber device can provide a depth profile of the blanching of inflammation. Such a profile may be an indicator of the depth of treatment achieved by the PDT. Our progress toward developing this diagnostic for use in our clinical PDT treatments of esophageal cancer patients is presented.

    Objective The purposes of this study were to (1) assess the clinicoepidemiological characteristics of esopha-geal cancer patients, (2) analyze the prognostic factors determining treatment failure and survival, and (3) evaluate the results of various treatment modalities for locoregional and disseminated disease and their ef ect on disease-free survival and overal survival (OS). Methods Clinicoepidemiological retrospective data from 81 esophageal cancer patients treated at the Na-tional Cancer Institute of Cairo between 2007 and 2011 were evaluated. Results The study showed that patients with esophageal cancer commonly present with local y advanced disease (87.7% had T-stage 3 and 12.3% had T-stage 4). There was a significant correlation between surgery and survival; patients who received radical surgery and postoperative radiation had a better median survival than patients who received radical radiotherapy (20 months vs. 16 months, respectively; P = 0.04). There was also a significant statistical correlation between radical concomitant chemoradiotherapy (NCRT) and pal iative treatment. Patients who received radical NCRT had a better median survival than patients who received pal-liative radiotherapy (16 months vs. 10 months, respectively; P = 0.001). The median fol ow-up period for al patients was 7 months. The median OS of the whole group was 12 months. The OS after 1 and 2 years was 57.8% and 15%, respectively. Conclusion High-dose NCRT is an acceptable alternative for patients unfit for surgery or with inoperable disease. High-dose radiation is more ef ective than low-dose radiation in terms of local control, time to relapse, and OS. Further study using a larger series of patients and introducing new treatment protocols is necessary for a final evaluation.

    Purpose: While trimodality therapy for esophageal cancer has improved patient outcomes, surgical complication rates remain high. The goal of this study was to identify modifiable factors associated with postoperative complications after neoadjuvant chemoradiation. Methods and Materials: From 1998 to 2011, 444 patients were treated at our institution with surgical resection after chemoradiation. Postoperative (pulmonary, gastrointestinal [GI], cardiac, wound healing) complications were recorded up to 30 days postoperatively. Kruskal-Wallis tests and χ{sup 2} or Fisher exact tests were used to assess associations between continuous and categorical variables. Multivariate logistic regression tested the association between perioperative complications and patient or treatment factors that were significant on univariate analysis. Results: The most frequent postoperative complications after trimodality therapy were pulmonary (25%) and GI (23%). Lung capacity and the type of radiation modality used were independent predictors of pulmonary and GI complications. After adjusting for confounding factors, pulmonary and GI complications were increased in patients treated with 3-dimensional conformal radiation therapy (3D-CRT) versus intensity modulated radiation therapy (IMRT; odds ratio [OR], 2.018; 95% confidence interval [CI], 1.104-3.688; OR, 1.704; 95% CI, 1.03-2.82, respectively) and for patients treated with 3D-CRT versus proton beam therapy (PBT; OR, 3.154; 95% CI, 1.365-7.289; OR, 1.55; 95% CI, 0.78-3.08, respectively). Mean lung radiation dose (MLD) was strongly associated with pulmonary complications, and the differences in toxicities seen for the radiation modalities could be fully accounted for by the MLD delivered by each of the modalities. Conclusions: The radiation modality used can be a strong mitigating factor of postoperative complications after neoadjuvant chemoradiation.

    Esophageal reconstruction with colon interposition is an alternative solution for the esophageal cancer patients who have partial gastrectomy. The aim of this study was to investigate the therapeutic effects of colon interposition among the esophageal carcinoma patients with partial gastrectomy. Under institutional review board approval, 32 esophageal carcinoma patients with a history of partial gastrectomy were included in this study. All the patients had been diagnosed and confirmed squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma by histopathological examination. Surgical approaches, complications and therapeutic results were analyzed in the current study. Thirty-two esophageal carcinoma patients (29 men, 3 women, median age 63.2 years) were included in this study. Isoperistaltic colon interposition was carried out on 14 patients; their 1-year and 2-year survival rate was 92.9% and 78.6%, respectively. Antiperistaltic colon interposition was carried out on 18 patients; their 1-year and 2-year survival rate was 88.9% and 77.8%, respectively. In which, cervical anastomotic leakage was observed on six patients. Colon interposition is an ideal surgical approach for the esophageal carcinoma patients who had partial gastrectomy. Isoperistaltic colon interposition is preferred, but antiperistaltic colon interposition has the advantage that a longer colon can be used.

    Paclitaxel (PTX) is broadly considered the drug of choice for treating human esophageal squamous cell cancer (ESCC). However, PTX resistance often ultimately leads to treatment failure. stathmin, or Op18, is a ubiquitously expressed 19-kDa cytosolic phosphoprotein that can integrate various cellular regulatory signals. stathmin overexpression could lead to resistance to chemotherapeutic agents. In this study we investigated the effect of stathmin gene silencing, using small interfering RNA (stathmin siRNA), on the efficacy of PTX in ESCC. Transfection of stathmin siRNA could significantly inhibit stathmin mRNA and protein levels in ESCC cell lines EC9706 and Eca-109. The silencing of stathmin combined with PTX significantly inhibited the proliferation of EC9706 and Eca-109 cells, with a significantly higher proportion of cells at G2/M phase and this antiproliferative effect was accompanied by an increase in apoptosis rates and morphology changes of EC9706 and Eca-109. Thus, combined chemotherapeutic agent PTX and stathmin siRNA could potentially enhance the therapeutic outcomes of PTX in treating ESCC.

    The best management for small mucosal esophageal cancer is generally endoscopic mucosal resection. However, for submucosal cancer and extensive mucosal caner, either radical surgery or radiation seems to be an equally efficacious option. Radiation therapy concurrent with chemotherapy is more effective than radiation therapy alone for patients with unresectable esophageal cancer. The key drugs are cisplatin and 5-fluorouracil. However, for patients with poor performance status or for aged patients, radiation therapy alone is still a choice of treatment. Surgery has generally been indicated for patients with resectable esophageal cancer. However, outcomes of concurrent chemoradiation therapy may be comparable with those of surgery. Therefore, a prospective randomized study should be performed to determine the best management for patients with resectable esophageal cancer. The usefulness of intra-cavitary irradiation for esophageal cancer has not been clarified. A prospective randomized trial with a large number of patients is necessary to determine the effectiveness of intra-cavitary irradiation. The best management for patients with loco-regionally recurrent esophageal cancer after surgery has not been determined. Intensive therapy should be considered if the site of recurrence is limited and the time interval from surgery to recurrence is long. Chemotherapy is essential in the management of patients with small cell esophageal cancer. However, the best local therapy has not been determined. (author)

    The comorbidity of depression with anxiety disorders is associated with poorer treatment outcomes, worse quality of life, poorer adherence to treatment, and greater suicide risk in cancer patients. To assess the risk of comorbid anxiety and depressive disorders after the diagnosis of esophageal cancer compared with a matched cohort by using the Taiwan National Health Insurance Research Database (NHIRD). We conducted a retrospective study of 28,454 patients (14,227 patients with esophageal cancer and 14,227 matched patients) who were selected from the NHIRD. Patients were observed for a maximum of 12 years to determine the incidence of new-onset anxiety and depressive disorders for which antidepressants had been prescribed. A Cox regression analysis was performed to identify the risk factors associated with anxiety and depressive disorders in esophageal cancer patients. The cumulative incidence of anxiety and depressive disorders in the esophageal cancer patients was significantly higher than that in the matched cohort (P anxiety and depressive disorders among the patients with esophageal cancer included cirrhosis, cerebrovascular disease, and surgical treatment. Esophageal cancer may be a prominent risk factor for anxiety and depressive disorders. Based on our data, we suggest that attention should be focused on esophageal cancer patients with comorbid cirrhosis and cerebrovascular disease and those who have received surgical interventions.

    Fifty-three cases with moderate or advanced esophageal and cardiac cancer treated by endoscopic microwave therapy are reported. The results showed that after 2 to 4 treatments, dysphagia was relieved in 52 (98%), esophageal re-expansion was seen in 48 (90%). Improvement was most pronounced in lesions predominantly shown as localized polypoid projection type. Biopsy after treatment was confirmed pathologically as necrosis in 24 cases. After treatment, the follow-up of 22 cases for over 3 months and 8 cases for over 6 months was carried out. 22/22 could maintain the therapeutic effectiveness and 5/8 were on soft diet (noodles and steamed bread). Microwave therapy is a palliative measure that can definitely improve the dysphagia in short term courses and prolong the survival. Microwave endoscopy, being easy in manipulation without complications, is very useful in the treatment of esophageal and cardiac cancers contra-indicated for surgery.

    To characterize the safety profile and effectiveness of esophageal dilation in head and neck cancer patients. A systematic review was undertaken for articles reporting outcomes of esophageal dilation in head and neck cancer patients. The Medline, Scopus, Web of Science, and Cochrane databases were searched in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Complications related to esophageal dilation in head and neck cancer patients was the primary outcome of interest. Success rates, demographic data, cancer staging, and treatment data were assessed secondarily. Statistical analyses included both qualitative and quantitative assessments. A limited meta-analysis and pooling of the data was performed using a random effects model. Of the collective 8,243 initial candidate articles, 15 retrospective studies containing data for a collective 449 patients were ultimately included in the analysis. There was significant heterogeneity in the outcomes data. With an overall complication rate of 10.6% (95% confidence interval [CI]: 4.1%,17%) and a pooled success rate of 72.9% (95% CI: 65.7%,80.1%) per patient, the articles generally supported the use of dilation. Head and neck cancer patients experience a higher rate of complications following dilation compared to patients with other causes of benign stricture. Esophageal dilation is effective in improving dysphagia, but these benefits are often transient and thus necessitate repeat interventions.

    Neoadjuvant therapy has been proven to be extremely valuable and is widely used for advanced esophageal cancer. However, a significant proportion of treated patients(60%-70%) does not respond well to neoadjuvant treatments and develop severe adverse effects. Therefore, predictive markers for individualization of multimodality treatments are urgently needed in esophageal cancer. Recently, molecular biomarkers that predict the response to neoadjuvant therapy have been explored in multimodal approaches in esophageal cancer and successful examples of biomarker identification have been reported. In this review, promising candidates for predictive molecular biomarkers developed by using multiple molecular approaches are reviewed. Moreover, treatment strategies based on the status of predicted biomarkers are discussed, while considering the international differences in the clinical background. However, in the absence of adequate treatment options related to the results of the biomarker test, the usefulness of these diagnostic tools is limited and new effective therapies for biomarker-identified nonresponders to cancer treatment should be concurrent with the progress of predictive technologies. Further improvement in the prognosis of esophageal cancer patients can be achieved through the introduction of novel therapeutic approaches in clinical practice.

    Full Text Available Context Development of a second primary malignancy after an index esophageal cancer is a rare event, primarily due to short survival of patients with esophageal cancer. However, the number of long-term esophageal cancer survivors has been increasing due to advances in early detection and therapy. Case report We report herein a case of pancreatic adenocarcinoma that developed three years after a successfully treated early-stage adenocarcinoma of the esophagus. A 70-year-old Caucasian male presented with vague complaints of nausea, vomiting and abdominal distention, with subsequent development of jaundice. A computed tomography scan of abdomen revealed a 2.9 cm soft tissue mass in the head of the pancreas and the patient underwent a Whipple’s procedure, with pathology confirming the diagnosis of pancreatic adenocarcinoma. Three years previously, the patient was successfully treated for adenocarcinoma of the esophagus via minimally invasive esophagogastrectomy. Despite chemoradiotherapy for localized disease and subsequent systemic chemotherapy for metastatic pancreatic cancer, the patient eventually succumbed to his illness. Conclusion We discuss the association between esophageal cancer and subsequent second malignancies, along with implications for surveillance and therapy.

    While several epidemiological studies have investigated the association between vitamin C and risk of esophageal cancer, the results remain inconsistent. In the present study, a meta-analysis was conducted to assess the impact of dietary vitamin C intake on esophageal cancer risk. Online databases were searched up to March 29, 2015, for studies on the association between dietary vitamin C intake and esophageal cancer risk. Pooled risk ratios (RRs) or odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using a random-effects model. Dose-response analyses were performed using the method of restricted cubic splines with four knots at percentiles of 5, 35, 65 and 95% of the distribution. Publication bias was estimated using Egger's tests and funnel plots. In all, 15 articles were included in this meta-analysis, including 20 studies, containing 7063 controls and 3955 cases of esophageal cancer. By comparing the highest vs. the lowest categories of vitamin C intake, we found that vitamin C was inversely associated with the risk of esophageal cancer [overall OR = 0.58, 95% CI = 0.49-0.68, I(2) = 56%]. A linear dose-response relationship was found. With an increase in dietary vitamin C intake of 50 mg/day, the risk of esophageal cancer statistically decreased by 13% (OR = 0.87, 95% CI = 0.80-0.93, p(linearity) = 0.0002). In conclusion, our analysis suggested that the higher intake of dietary vitamin C might have a protective effect against esophageal cancer.

    Midkine, a heparin-binding growth factor, is expressed in numerous cancer tissues and is reportedly elevated in patients with various neoplasms. The aim of this study was to evaluate the clinicopathological significance of serum midkine concentration (S-MK) in patients with superficial esophageal squamous cell carcinoma (SCC). Pretreatment S-MK was measured by enzyme-linked immunosorbent assay in 135 healthy controls, 16 patients with benign esophageal disease, and 60 patients with primary superficial esophageal squamous cell cancer (SESCC). All patients with SESCC underwent curative resection. The disease was staged according to TNM/UICC guidelines. Serum concentrations of carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC-Ag), and cytokeratin 19 fragment (CYFRA21-1) were also evaluated in the same populations. S-MK in patients with SESCC (388+/-411 pg/ml) was significantly higher than in benign esophageal disease or healthy controls (183+/-73 and 154+/-76 pg/ml, respectively). Using the mean + 2 standard deviations of healthy control S-MK (300 pg/ml) as the cut-off level, 50% of patients with esophageal SESCC were deemed positive. This S-MK positivity rate for detecting SESCC was significantly higher than for other tumor markers. Thus, S-MK may be useful as a tumor marker to detect SESCC.

    Pre- and peri-operative strategies are becoming standard for the management of localized gastro-esophageal cancer. For localized gastric/gastro-esophageal junction (GEJ) cancer there are conflicting data that a peri-operative approach with cisplatin-based chemotherapy improves survival, with the benefits seen in esophageal cancer likely less than a 5-10% incremental improvement. Further trends toward improvement in local control and survival, when combined chemotherapy and radiation therapy are given pre-operatively, are suggested by recent phase III trials. In fit patients, a significant survival benefit with pre-operative chemoradiation is seen in those patients who achieve a pathologic complete response. In esophageal/GEJ cancer, definitive chemoradiation is now considered in medically inoperable patients. In squamous cell carcinoma of the esophagus, surgery after primary chemoradiation is not clearly associated with an improved overall survival, however, local control may be better. In localized gastric/GEJ cancer, the integration of bevacizumab with pre-operative chemotherapy is being explored in large randomized studies, and with chemoradiotherapy in pilot trials. The addition of anti-epidermal growth factor receptor and anti-human epidermal growth factor receptor-2 antibody treatment to pre-operative chemoradiation continues to be explored. Early results show the integration of targeted therapy is feasible. Metabolic imaging can predict early response to pre-operative chemotherapy and biomarkers may further predict response to pre-operative chemo-targeted therapy. A multimodality approach to localized gastro-esophageal cancer has resulted in better outcomes. For T3 or node-positive disease, surgery alone is no longer considered appropriate and neo-adjuvant therapy is recommended. The future of neo-adjuvant strategies in this disease will involve the individualization of therapy with the integration of molecular signatures, targeted therapy, metabolic imaging

    Full Text Available Background: Esophageal cancer is commonly treated with surgery, concurrent chemoradiotherapy (CCRT, or a combination of both. The correlation between the hematological parameters during CCRT and early survival of esophageal cancer has not been fully evaluated. Materials And Methods: We analyzed the records of 65 esophageal cancer patients treated by CCRT between 2007 and 2010 retrospectively. The association between CCRT-associated myelosuppression, demographic variables, and survival rates were analyzed by univariate and multivariate analysis. Results: The univariate analysis showed that tumor extent of T3-4, a higher stage of tumor, a lower albumin level, grade 3 or higher anemia and thrombocytopenia, and interruptions in treatment affected survival rates. Further, the multivariate analysis revealed that stage IV (P = 0.030 is an independently negative prognostic factor for a one-year survival rate. Stage IV (P = 0.035, tumor extent of T3-4 (P = 0.002, and grade 3-4 thrombocytopenia (P = 0.015 are independently negative prognostic factors for a two-year survival rate. Conclusions: Severe decrease in platelet count during CCRT independently affects survival of esophageal cancer patients in addition to stage of the tumor.

    A 68-year-old man underwent subtotal esophagectomy with two fields lymphadenectomy and postoperative chemotherapy so called low dose FP therapy for advanced esophageal cancer (Stage IIIa, pT 3, pN 1, M 0) in October 1999. As he was diagnosed with a recurrence of esophageal cancer as metastatic lymph node tumors which were placed in the right anterocervical and supraclavicular region in March 2001, he underwent enucleation of metastatic lymph node tumors and postoperative chemoradiation therapy, so-called low-dose FP-R therapy. Recently, since other metastatic lymph node tumors in the neck appeared again in August 2001, he underwent radical neck lymph node dissection and postoperative chemoradiation treatment, so-called FAP-R therapy. In October 2003, a chest CT showed multiple lung tumors. He was diagnosed with multiple metastatic lung tumors originating from esophageal cancer. Then, two courses of a combined chemotherapy consisting of TS-1 and CDDP were administered at an interval of one month. We judged the effect of this chemotherapy to be a partial response (PR), because the largest metastatic lung tumor 18 mm in diameter showed a reduction rate of 81.9%, and other tumors had almost disappeared in the chest CT after the combined therapy. No severe adverse effects of more than grade 3 were observed during this combined therapy. This combined chemotherapy consisting of TS-1 and CDDP may prove effective for treating recurrent cases of esophageal cancer.

    For recurrent esophageal cancer after primary definitive radiotherapy, no general treatment guidelines are available. We evaluated the toxicities and clinical outcomes of re-irradiation (re-RT) for recurrent esophageal cancer. We analyzed 10 patients with recurrent esophageal cancer treated with re-RT after primary definitive radiotherapy. The median time interval between primary radiotherapy and re-RT was 15.6 months (range, 4.8 to 36.4 months). The total dose of primary radiotherapy was a median of 50.4 Gy (range, 50.4 to 63.0 Gy). The total dose of re-RT was a median of 46.5 Gy (range, 44.0 to 50.4 Gy). The median follow-up period was 4.9 months (range, 2.6 to 11.4 months). The tumor response at 3 months after the end of re-RT was complete response (n = 2), partial response (n = 1), stable disease (n = 2), and progressive disease (n = 5). Grade 5 tracheoesophageal fistula developed in three patients. The time interval between primary radiotherapy and re-RT was less than 12 months in two of these three patients. Late toxicities included grade 1 dysphagia (n = 1). Re-RT of recurrent esophageal cancer after primary radiotherapy can cause severe toxicity.

    The aim of this study was to more clearly define the clinical course of leptomeningeal carcinomatosis due to esophageal cancer. A single institution retrospective case series was conducted. Additionally, a systematic review of the literature was performed. We present a large case series (n = 7) of leptomeningeal carcinomatosis due to esophageal cancer. Our case series and systematic review of the literature report similar findings. In our series, we report a predominance of male patients (86%) with adenocarcinoma histology (77%). Variable onset of leptomeningeal involvement of esophageal cancer in relation to the original diagnosis of the primary disease (5 months to 3 years and 11 weeks) was noted. Disease progresses quickly and overall survival is poor, measured in weeks (2.5-16 weeks) from the diagnosis of leptomeningeal involvement. Four of our patients initiated whole-brain radiation therapy with only two completing the course prior to clinical deterioration. Our patient with the longest survival (16 weeks) received intrathecal topotecan and oral temozolomide. Leptomeningeal carcinomatosis secondary to esophageal cancer has a poor prognosis. A clearly beneficial treatment modality is lacking.

    F-18-FDG PET has gained acceptance for staging of esophageal cancer. However, FDG is not tumor specific and false-positive results may occur by accumulation of FDG in benign tissue. The tracer F-18-fluoro-3'-deoxy-3'-L-fluorothymidine (F-18-FLT) might not have these drawbacks. The aim of this study

  8. Esophagectomy as a Treatment Consideration for Early-Stage Esophageal Cancer and High-Grade Dysplasia.

    2016-10-01

    In recent years, a number of endoluminal procedures such as endoscopic resection and thermal ablation have emerged as less invasive treatment options for early esophageal cancer. These therapies have demonstrated excellent oncologic outcomes for dysplasia as well as intramucosal cancers. However, few studies have directly compared long-term outcomes of endoscopic therapy versus traditional esophagectomy. Current esophagectomy techniques now deliver consistently good outcomes in the hands of experienced surgeons at high volume centers, and this option should be considered an important treatment consideration for early esophageal cancer. Under current recommendations, esophagectomy should be considered for tumors invading the submucosa, tumors with high-risk pathologic features, bulky tumors, multinodular tumors, tumors within a long segment of Barrett's esophagus, and tumors adjacent to a hiatal hernia. Likewise, individual patient factors and comorbidities must also be considered when determining the best treatment for a patient with early esophageal cancer. The risk of missing metastatic disease or recurrence that is associated with endoscopic treatment must be weighed against the surgical risks of esophagectomy. With these considerations in mind, the aim of this article is to review the current guidelines and literature that explore the role of esophagectomy for early esophageal malignancy in the era of endoscopic therapies.

    Here we explored the potential effect of PP121, a novel dual inhibitor of tyrosine and phosphoinositide kinases, against human esophageal cancer cells. We showed that PP121 exerted potent cytotoxic effect in primary (patient-derived) and established (Eca-109, TE-1 and TE-3 lines) esophageal cancer cells, possibly through activating caspase-3-dependnent apoptosis. PP121 was, however, non-cytotoxic to the normal human esophageal epithelial cells (EECs). At the molecular level, we showed that PP121 blocked Akt-mTOR (mammalian target of rapamycin) activation in esophageal cancer cells, which was restored by introducing a constitutively-active Akt (CA-Akt). Yet, CA-Akt only partly inhibited cytotoxicity by PP121 in Eca-109 cells. Importantly, we showed that PP121 inhibited nuclear factor kappa B (NFκB) signaling activation in esophageal cancer cells, which appeared independent of Akt-mTOR blockage. In vivo, oral administration of PP121 remarkably inhibited Eca-109 xenograft growth in nude mice, and significantly improved mice survival. Further, the immunohistochemistry (IHC) and Western blot assays analyzing xenografted tumors showed that PP121 inhibited Akt-mTOR and NFκB activations in vivo. Together, we demonstrate that PP121 potently inhibits esophageal cancer cells in vitro and in vivo, possibly through concurrently inhibiting Akt-mTOR and NFκB signalings. - Highlights: • PP121 is cytotoxic against primary and established esophageal cancer cells. • PP121 induces caspase-3-dependnent apoptosis in esophageal cancer cells. • PP121 blocks Akt-mTOR activation in esophageal cancer cells. • PP121 inhibits NFκB activation, independent of Akt-mTOR blockage. • PP121 inhibits Eca-109 xenograft growth and Akt-mTOR/NFκB activation in vivo.

    AIM: To characterize the histological types of esophageal and cardiac mucosa by endoscopic survey of a population in a high-risk area of esophageal cancer of China.METHODS: A selected cohort of residents in Cixian County during December 2001 and May 2002 was surveyed by using Lugol′s staining, followed by computer-based statistical analysis of the data with SPSS 10.0 software.RESULTS: Histologically, the detection rates of squamous epithelial acanthosis, squamous epithelial atrophy, and basal cell hyperplasia in the esophagus were 1.9% (38/2 013),0.1% (3/2 013) and 0.9% (18/2 013) respectively, and those of mild, moderate, and severe esophagitis were 34.9% (703/2 013), 1.6% (33/2 013) and 0.2% (2/2 013)respectively. Mild, moderate, and severe esophageal dysplasia were detected in 8.6% (172/2 013), 7.8% (157/2 013) and 2.6% (53/2 013) respectively in the selected population,whereas in situ carcinoma, intramucosal carcinoma, invasive squamous carcinoma of the esophagus in 2.5% (50/2 013),0.2% (4/2 013) and 0.7% (14/2 013) respectively. The detection rates of non-atrophic gastritis and atrophic gastritis of the cardia were 36.3% (730/2 013) and 11.5% (232/2 013) respectively,with mild and severe dysplasia of the cardia detected in 2.5% (51/2 013) and 0.8% (17/2 013), respectively, in this population; the rates of intramucosal adenocarcinoma and invasive adenocarcinoma of the cardia were 0.1% (3/2 013)and 0.8% (17/2 013) respectively. The detection rate of esophageal cancer at early stage was 79.4% (54/68). The survey rate (ratio of examined population to expected population) was 73.8% (2 013/2 725).CONCLUSION: Histologic types of the esophageal and cardiac mucosa were characterized by endoscopic survey in a high-risk population of esophageal cancer, which may help the early detection and treatment of esophageal and cardiac cancers and dysplasia, and reduce the mortality of such malignancies.

    We investigated the outcome and the prognostic factors of patients with locally advanced esophageal cancer who were treated with concurrent chemo-radiotherapy. Two hundred forty six patients with esophageal cancer that were treated by radiotherapy between January 1994 and July 2007. Of these, 78 patients who received radiotherapy of {>=}45 Gy with concurrent chemotherapy were retrospectively enrolled in this study. We included patients stages IIA, IIB, III, IVA, and IVB with supraclavicular metastasis in the middle/lower esophageal cancer or celiac node metastasis in cervical or upper/middle thoracic esophageal cancer. The median radiation dose was 54 Gy and the combination chemotherapy with 5-FU and cisplatin (FP chemotherapy) was given concurrently with radiotherapy in most patients (88%). The follow-up period ranged from 2 to 117 months (median 14 months). The treatment response of the 54 patients could be evaluated by computerized tomography or endoscopy. A complete response (CR) was observed in 17 patients, whereas a partial response was observed in 18 patients. In patients with a CR, the median recurrence time was 20 months and the first relapse sites constituted a locoregional failure in 3 patients and a distant failure in 7 patients. The 1-, 2-, and 5-year overall survival (OS) rates were 58.9%, 21.7%, and 12.2%, respectively. The median survival period was 14 months. A univariate analysis indicated that the treatment response and cycles of FP chemotherapy were significant prognostic factors for OS. Daily or weekly administration of cisplatin as a radiosensitizer showed a better treatment response than FP chemotherapy. This study has shown that results of concurrent chemo-radiotherapy in patients with locally advanced esophageal cancer is comparable to those of other studies. Daily or weekly cisplatin administration may be considered as an alternative treatment in patients that are medically unfit for FP chemotherapy.

    A man in his 60s was admitted for the treatment of advanced cervical esophageal cancer with metastasis to the lymph nodes and advanced tongue cancer with metastasis to the lymph nodes. Esophageal cancer was suspected to have invaded the trachea. The tongue cancer was located on the left side and had invaded beyond the median line of the tongue. Both cancers were pathologically diagnosed as squamous cell carcinomas. Therefore, it was determined that pharyngo-laryngo- esophagectomy and total glossectomy were required prior to the treatment. However, after 2 courses of docetaxel/cisplatin/ 5-FU combined induction chemotherapy, both cancers remarkably decreased; consequently, an esophagectomy to preserve laryngeal function and partial glossectomy could be performed simultaneously. The patient is well without recurrence 1 year post-surgery.

    Esophageal cancer is currently the 8th most common cancer worldwide and the 6th leading cause of cancer-related mortality. Despite remarkable advances, the mortality for those suffering from esophageal cancer remains high, with 5-year survival rates of less than 20%. In part, because most patients present with late-stage disease, long-term survival even after resection and therapy is disappointingly low. As we will discuss in this review, multiple characteristics specific to the disease stage and patient must be considered when choosing a treatment plan. This article will summarize current standard therapies, potential application of chemoprevention drugs and the promise and partial failure of personalized medicine, as well as novel treatments addressing this disease.

    Esophageal cancer (EC) is one of common malignant tumors, and the incidence and mortality of EC in China rank the first place in the world. Because of the occult onset, the early atypical symptoms, and the lack of effective early diagnostic methods, most of patients are diagnosed at an advanced stage of the disease and lost the chance of surgery. Comprehensive treatment including palliative medical treatment, molecular targeted therapy, immunotherapy and so on is appropriate for these patients. How to choose the chemotherapy regimen and formulate reasonable treatment plan has become a hot spot in clinical research. Molecular targeted drugs have become a new developmental direction in cancer treatment because of their high specificity and antitumor activity, but the effects on esophageal cancer remain controversial. With the development of immune check point blockade treatment, breakthrough has been made in tumor immunotherapy, which has become an important means in cancer comprehensive treatment and shown a good prospect of treatment.

    Telomerase is a type of reverse transcriptase that is overexpressed in almost all human tumor cells, but not in normal tissues, which provides an opportunity for radiosensitization targeting telomerase. Zidovudine, abacavir and lamivudine are reverse transcriptase inhibitors that have been applied in clinical practice for several years. We sought to explore the radiosensitization effect of these three drugs on human esophageal cancer cell lines. Eca109 and Eca9706 cells were treated with zidovudine, abacavir and lamivudine for 48 h before irradiation was administered. Samples were collected 1 h after irradiation. Clonal efficiency assay was used to evaluate the effect of the combination of these drugs with radiation doses of 2, 4, 6 and 8 Gy. DNA damage was measured by comet assay. Telomerase activity (TA) and relative telomere length (TL) were detected and evaluated by real-time PCR. Apoptosis rates were assessed by flow cytometric analysis. The results showed that all the drugs tested sensitized the esophageal squamous cell carcinoma (ESCC) cell lines to radiation through an increase in radiation-induced DNA damage and cell apoptosis, deregulation of TA and decreasing the shortened TL caused by radiation. Each of the drugs investigated (zidovudine, abacavir and lamivudine) could be used for sensitizing human esophageal cancer cell lines to radiation. Consequently, the present study supports the potential of these three drugs as therapeutic agents for the radiosensitization of esophageal squamous cell cancer.

    Full Text Available Objective: We aimed to investigate the SUVmax of primary tumor and metastatic lymph node in predicting survival in patients with esophageal cancer. Methods: We retrospectively analyzed patients with esophageal cancer between 2009 and 2011 who had FDG positronemission tomography (PET/computed tomography (CT. All patients were followed-up to 2013. Clinical staging, SUVmax of primary tumor and metastatic lymph node were evaluated. Results: One hundred seven patients were included in the study. All patients were followed-up between 2 and 49 months. The mean SUVmax of primary tumor and metastatic lymph node were 19.3±8.8 and 10.4±9.1, respectively. Metastatic lymph node SUVmax had an effect in predicting survival whereas primary tumor SUVmax did not have an effect (p=0.014 and p=0.262, respectively. Multivariate Cox regression analysis showed that clinical stage of the disease was the only independent factor predicting survival (p=0.001. Conclusion: Among patients with esophageal cancer, the value of primary tumor SUVmax did not have an effect on survival. Clinical stage assessed with FDG PET/CT imaging was found to predict survival in esophageal carcinoma. Additionally, lymph node SUVmax was identified as a new parameter in predicting survival in the present study

    In this clinical study we investigated the use and results of the LigaSure Vessel Sealing Sytem (LVSS) (Valleylab, Boulder, CO) compared with conventional surgery in esophageal cancer resection. The LVSS (Valleylab) is a device with a hemostatic design frequently used in abdominal surgery. Sixty patients (n = 30 in each group) with esophageal cancer from a single center were evaluated to undergo esophagectomy using either the LVSS or conventional clamping methods. The main outcome measures (ie, operating time, intraoperative blood loss, and postoperative course) were then compared. In resections performed using the LVSS, operation duration (307 +/- 35 minutes vs 260 +/- 35 minutes; p = 0.000), intraoperative blood loss (average 533 +/- 211 mL vs 390 +/- 256 mL; p = 0.022), and postoperative drainage volumes (abdomen, 70 +/- 86 mL vs 40 +/- 61 mL; p = 0.122; thorax, 690 +/- 646 mL vs 540 +/- 359 mL; p = 0.271) all decreased. The LVSS is easy to use and a reliable method in esophageal cancer surgery. Compared with conventional hemostatic techniques a reduction in intraoperative and postoperative blood loss, and a shortening of operation duration were determined. We believe that the use of the LVSS in esophageal surgery will become even more widespread in the future.

    We herein present a case in which we used a totally laparoscopic approach for early gastric cancer accompanied by a huge hiatal hernia. An 80-year-old Japanese woman was referred with a chief complaint of dysphagia. A clinical diagnosis of early gastric cancer, T1b (SM) N0M0, stage IA, accompanied by hiatal hernia, was made. Distal gastrectomy with D1 plus lymphadenectomy was carried out. After the gastrectomy, the hernial sac was excised and the hernial orifice was closed. Reconstruction using the Roux-en-Y method was selected. The postoperative course was uneventful and she was discharged on postoperative day 10.

    1998-05-01

    We performed esophageal endoscopy with concurrent chemo-radiotherapy for lung cancer in 19 patients. Endoscopical examination proved that seven patients (36.8%) had esophageal erosion or coating (grade 2), four patients (21.1%) had ulcer or bleeding (grade 3) confined to the radiation field, and only one patient (5.3%) had severe symptoms (WHO grade 3). There was a discrepancy between patients` symptoms and endoscopical findings. Endoscopically proven esophagitis, that is, erosion or coating (grade 2), and ulcer or bleeding (grade 3), was more frequent in the daily low-dose chemotherapy group (5/5) than in the full dose chemotherapy group (5/14) (p<0.05). One patient with grade 3 endoscopical damage showed less recovery in spite of three months medication. In concurrent radiochemotherapy in which the radiation field includes the esophagus, careful attention should be given to radiation esophagitis, which may be underestimated when assessed on the basis of subjective symptoms alone. Therefore, endoscopy is recommended even if patients have few complaints, and once the esophageal ulcer is proven (grade 3), it should be closely followed up using endoscopy. (author)

    This study aimed to investigate whether glucose transporter-1 (GLUT-1) expression in a pretreatment esophageal cancer biopsy was predictive of clinical outcomes in patients with esophageal cancer undergoing concurrent chemoradiotherapy (CRT). A total of 25 patients with esophageal cancer treated with concurrent CRT were reviewed. Radiotherapy was administered up to total doses of 40-66.6 Gy (median 66.6 Gy) with a single fraction of 1.8-2 Gy. Regarding chemotherapy, cisplatin (80 mg/m(2) on day 1) and 5-fluorouracil (800 mg/m(2) on days 2-6) were used concurrently with radiotherapy, every 3-4 weeks for a total of 1-2 courses. Tissue samples from esophageal carcinoma were obtained from the 25 patients by biopsy prior to concurrent CRT, and a semiquantitative analysis of GLUT-1 expression was performed using immunohistochemical staining. High GLUT-1 expression was observed in 7 of 25 (28%) patients, and GLUT-1 expression was significantly correlated with clinical T stage (p=0.0454), clinical N stage (p=0.0324) and initial response to CRT (p=0.0185). Patients with a high GLUT-1 expression had significantly poorer local control (LC) (5-year LC 28.6%) than those with a low expression (5-year LC 73.4%, pGLUT-1 and the number of chemotherapy courses were independent prognostic factors for LC. Patients with a high GLUT-1 expression had significantly lower recurrence-free survival (RFS) compared to those with a low GLUT-1 expression (p=0.0405). Multivariate analysis revealed that GLUT-1, the number of chemotherapy courses and clinical M stage were independent prognostic factors for RFS. GLUT-1 expression was significantly correlated with clinical T stage, clinical N stage and initial response to concurrent CRT, and was predictive of LC and RFS for patients with esophageal cancer treated with concurrent CRT.

    Matrine, as a member of Sophora family, is an alkaloid found in plants, and produces plethora pharmacological effects, including anti-cancer effects. However, the mechanism involved remains largely unknown. This study is conducted to investigate the anti-cancer mechanisms of matrine in human esophageal cancer in vitro and in vivo. In human esophageal cancer cell Eca-109, matrine significantly decreased the cell viability in a dose-dependent manner, and induced apoptosis as well as cell cycle arrest in G0/G1 phase by up-regulation of P53 and P21. The expression of several apoptosis-related proteins in cells and tumor tissues were evaluated by Western blot analysis. We found that matrine induced cell apoptosis by down-regulation of the ratio of BCL-2/BID and increasing activation of caspase-9. Further studies indicated that matrine induced apoptosis of Eca-109 was through the mitochondria-mediated internal pathway, but not by death receptor-mediated extrinsic apoptotic pathway, which was confirmed by the fact that Bid translocated from the nucleus to mitochondria during the process of the apoptosis induced by matrine. In vivo study found that matrine effectively inhibited the tumor formation of Eca-109 cells in nude mice. Our study suggests that matrine could serve as a potential novel agent from natural products to treat esophageal cancer.

    Full Text Available Esophageal cancer is one of the most common cancers world-wide and also the most common cause of cancer death. In this paper, we present an adaptive fuzzy reasoning algorithm for rule-based systems using fuzzy Petri nets (FPNs, where the fuzzy production rules are represented by FPN. We developed an adaptive fuzzy Petri net (AFPN reasoning algorithm as a prognostic system to predict the outcome for esophageal cancer based on the serum concentrations of C-reactive protein and albumin as a set of input variables. The system can perform fuzzy reasoning automatically to evaluate the degree of truth of the proposition representing the risk degree value with a weight value to be optimally tuned based on the observed data. In addition, the implementation process for esophageal cancer prediction is fuzzily deducted by the AFPN algorithm. Performance of the composite model is evaluated through a set of experiments. Simulations and experimental results demonstrate the effectiveness and performance of the proposed algorithms. A comparison of the predictive performance of AFPN models with other methods and the analysis of the curve showed the same results with an intuitive behavior of AFPN models.

    Clinical stage II/III esophageal cancer (EC), as defined by the Japanese Classification, relapses at a moderately high rate even after curative resection. The number of lymph node metastases is known to be associated with tumor relapse. Recently, the prognostic significance of occult metastatic lymph nodes (MLNs), as well as that of overt MLNs, has been reported. The aim of this study was to investigate the impact of the total number of MLNs including occult MLNs on postoperative relapse in clinical stage II/III EC. One hundred and five patients with clinical stage II/III EC who underwent esophagectomy accompanied by radical lymphadenectomy at the Department of Surgical Oncology in Osaka City University Hospital between January 2000 and October 2008 were included in this study. Occult MLNs, metastases not detected by hematoxylin-eosin staining, were identified by immunohistochemistry (IHC) using antipancytokeratin antibody AE1/AE3. The clinicopathological features of occult MLNs were compared between the relapse and no relapse groups. A total of 6558 lymph nodes (1357 from two-field dissection and 5201 from three-field dissection) were examined by IHC staining; 362 overt MLNs and 143 occult MLNs were detected. The number of occult MLNs increased in proportion to the International Union Against Cancer pathological (p)N-status and pStage. When the number of occult MLNs was added to the number of pNs, the number of total MLNs was associated with postoperative relapse. With respect to tumor, node, metastasis stage, 6 of 22 patients (27%) who were pathological node-negative converted to node-positive by considering total MLNs. The number of N3 patients with relapse increased markedly with restaging by total MLNs. The number of total MLNs, but not overt MLNs, was an independent prognostic factor on multivariate analysis. These results suggest that occult MLNs were often found, and they were associated with postoperative relapse of resectable esophageal cancer. The total

    Despite substantial efforts at early diagnosis, accurate staging and advanced treatments, esophageal cancer (EC) continues to be an ominous disease worldwide. Risk factors for esophageal carcinomas include obesity, gastroesophageal reflux disease, hard-alcohol use and tobacco smoking. Five-year survival rates have improved from 5% to 20% since the 1970s, the result of advances in diagnostic staging and treatment. As the most sensitive test for locoregional staging of EC, endoscopic ultrasound (EUS) influences the development of an optimal oncologic treatment plan for a significant minority of patients with early cancers, which appropriately balances the risks and benefits of surgery, chemotherapy and radiation. EUS is costly, and may not be available at all centers. Thus, the yield of EUS needs to be thoughtfully considered for each patient. Localized intramucosal cancers occasionally require endoscopic resection (ER) for histologic staging or treatment; EUS evaluation may detect suspicious lymph nodes prior to exposing the patient to the risks of ER. Although positron emission tomography (PET) has been increasingly utilized in staging EC, it may be unnecessary for clinical staging of early, localized EC and carries the risk of false-positive metastasis (over staging). In EC patients with evidence of advanced disease, EUS or PET may be used to define the radiotherapy field. Multimodality staging with EUS, cross-sectional imaging and histopathologic analysis of ER, remains the standard-of-care in the evaluation of early esophageal cancers. Herein, published data regarding use of EUS for intramucosal, local, regional and metastatic esophageal cancers are reviewed. An algorithm to illustrate the current use of EUS at The University of Texas MD Anderson Cancer Center is presented.

    Full Text Available Abstract Background The roles of mitochondria in energy metabolism, the generation of ROS, aging, and the initiation of apoptosis have implicated their importance in tumorigenesis. In this study we aim to establish the mutation spectrum and to understand the role of somatic mtDNA mutations in esophageal cancer. Methods The entire mitochondrial genome was screened for somatic mutations in 20 pairs (18 esophageal squamous cell carcinomas, one adenosquamous carcinoma and one adenocarcinoma of tumor/surrounding normal tissue of esophageal cancers, using temporal temperature gradient gel electrophoresis (TTGE, followed by direct DNA sequencing to identify the mutations. Results Fourteen somatic mtDNA mutations were identified in 55% (11/20 of tumors analyzed, including 2 novel missense mutations and a frameshift mutation in ND4L, ATP6 subunit, and ND4 genes respectively. Nine mutations (64% were in the D-loop region. Numerous germline variations were found, at least 10 of them were novel and five were missense mutations, some of them occurred in evolutionarily conserved domains. Using real-time quantitative PCR analysis, the mtDNA content was found to increase in some tumors and decrease in others. Analysis of molecular and other clinicopathological findings does not reveal significant correlation between somatic mtDNA mutations and mtDNA content, or between mtDNA content and metastatic status. Conclusion Our results demonstrate that somatic mtDNA mutations in esophageal cancers are frequent. Some missense and frameshift mutations may play an important role in the tumorigenesis of esophageal carcinoma. More extensive biochemical and molecular studies will be necessary to determine the pathological significance of these somatic mutations.

    To find genes involved in tumorigenesis and the development of esophageal cancer, the suppression subtractive hybridization (SSH) method was used to identify genes that are overexpressed in esophageal cancer tissues compared to normal esophageal tissues. In our SSH library, the forkhead box O3 (FOXO3), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and myeloid differentiation primary response 88 (MYD88) genes were the most highly upregulated genes, and they were selected for further studies because of their potential role in the induction of autophagy. Upregulation of these genes was also observed in clinical samples using qRT-PCR. In addition, coexpression analysis of the autophagy-related genes Beclin1, ATG12, Gabarapl, PIK3C3, and LC3 demonstrated a significant correlation between the differentially overexpressed genes and autophagy. Autophagy is an important mechanism in tumorigenesis and the development of chemoresistance in cancer cells. The upregulation of FOXO3, GAPDH, and MYD88 variants in esophageal cancer suggests a role for autophagy and provides new insight into the biology of esophageal cancer. We propose that FOXO3, GAPDH, and MYD88 are novel targets for combating autophagy in esophageal cancer.

    Recent evidence indicates that exosomes can mediate certain microRNAs (miRNAs) involved in a series of biological functions in tumor occurrence and development. Our previous studies showed that microRNA-21 (miR-21) was abundant in both esophageal cancer cells and their corresponding exosomes. The present study explored the function of exosome-shuttling miR-21 involved in esophageal cancer progression. We found that exosomes could be internalized from the extracellular space to the cytoplasm. The exosome-derived Cy3-labeled miR-21 mimics could be transported into recipient cells in a neutral sphingomyelinase 2 (nSMase2)-dependent manner. miR-21 overexpression from donor cells significantly promoted the migration and invasion of recipient cells by targeting programmed cell death 4 (PDCD4) and activating its downstream c-Jun N-terminal kinase (JNK) signaling pathway after co-cultivation. Our population plasma sample analysis indicated that miR-21 was upregulated significantly in plasma from esophageal cancer patients and showed a significant risk association for esophageal cancer. Our data demonstrated that a close correlation existed between exosome-shuttling miR-21 and esophageal cancer recurrence and distant metastasis. Thus, exosome-shuttling miR-21 may become a potential biomarker for prognosis among esophageal cancer patients.

    Background Cancer of the esophagus and gastroesophageal junction remains a virulent malignancy with poor prognosis. Rapid progresses were made in chemotherapeutic agents and the development of molecular markers allowed better identification of candidates for targeted therapy. This study aimed to identify the candidate peptides used for anti-angiogenic therapy of esophageal cancer by in vivo screening C7C peptide library for peptides binding specifically to blood vessels of human esophageal cancer.Methods The phage displayed C7C peptide library was injected intravenously into mice bearing human esophageal tumor xenografts under renal capsule. After 5 rounds of screening, 13 clones were picked up individually and sequenced.During each round of screening, titers of phage recovery were calculated from tumor xenograft and control tissues.Homing of these 9 peptides to tumor vessel was detected by calculating phage titers in the tumor xenograft and control tissues (lung and spleen) after each phage was injected into mice model, and compared with the distribution of phage M13 and Ⅷ-related antigen in tumor xenograft by immunohistochemical staining. Comparisons among groups of data were made using one-way analysis of variance (ANOVA), followed by the Bonferroni multiple comparisons test.Results The number of phage recovered from tumor tissue of each round increased gradually in tumor group while decreased in control groups (P <0.01 in tumor and spleen, P <0.05 in lung). Immunohistochemical staining showed similar staining pattern with M13 antibody or Ⅷ-related antigen antibody, suggesting that phages displaying the selected peptides could home to blood vessel of human esophageal cancer. According to their DNA, 9 corresponding peptide sequences were deduced. And the homing ability to blood vessel of phages displaying the selected peptides was confirmed by comparing with their recovery in tumor and control tissues. Two motifs, YSXNXW and PXNXXN, were also obtained by

    Aim: Esophageal cancer is one of the major types of cancers, causing death of approximately 5% of all cancer deaths. This is due, in large part, to both relatively ineffectual and unavailable treatment. In order to develop an effective treatment strategy against esophageal cancer, it is important to target metastatic genes. In the present study, we have used a cancer-associated ifbroblast (CAF) cell line derived from culturing peripheral blood mononuclear cells from a metastatic esophageal cancer patient to see whether chitosan nanoparticles (Ch-Np) treatment can modulate the metastatic phenotype of CAF cells by using various cellular and molecular markers.Methods: A CAF cell line was developed from peripheral blood mononuclear cells (PBMC) from a metastatic esophageal cancer patient. The cells were treated with 100 µg/mL of chitosan nanoparticlein vitro for the morphological and oncogenic characteristic studies, along with the expression of various genes involved in process of tumor development and metastasis. Techniques such as Light and Phase Contrast Microscopy, cell growth rate, Scratch metastatic assay, and molecular proifling were carried out to see changes in CAF cells before and after Ch-Np treatment.Results: It was observed that CAF cells grew in monolayer and had a doubling time of 25 ± 0.38 h. Morphologically, the cells had a ifbroblastic appearance. After treatment with 100 µg/mL of Ch-Npin vitro, there was an increased doubling time to 30 ± 0.83 h. Similarly, Scratch Assay showed an inhibition in the metastatic property of these cells. These ifndings were conifrmed with gene expression studies. It was also observed that there was complete down-regulation of metastatic genes MMP1 and MMP9 and chemokines such as CXCR-4, CXCR-7, CCR-5, and SDF-1, indicating that Ch-Np inhibited the metastatic characteristic of CAF cells.Conclusion: This study has shown that there was an inhibition of metastatic properties of CAF cells after treatment with Ch

    In the present TNM classification, involvement of supraclavicular nodes is defined as distant metastases. However, the therapeutic value of supraclavicular node dissection remains controversial. The purpose of this study was to evaluate the survival benefit of dissection of metastases to the supraclavicular lymph nodes in patients with thoracic esophageal carcinoma by using a large nationwide registry of esophageal cancer maintained by the Japanese Esophageal Society. The study group comprised 1309 patients with thoracic esophageal carcinoma treated in 2001, 2002, and 2003, who underwent esophagectomy with 3-field dissection for curative intent, and in whom the locations of pathologic metastatic lymph nodes and outcome evaluations were available. Of 1309 patients, 559 (42.7%) had no nodal metastases, 560 (42.8%) had at least 1 positive node but were supraclavicular node-negative, and 190 (14.5%) had supraclavicular node metastases. The 5-year survival was 73.7% for patients with N0, 40.4% for node-positive patients without supraclavicular node disease, and 24.1% for patients with supraclavicular node metastasis. In a multivariate analysis, male sex (Pnodes (PSupraclavicular node metastasis was not significant (P=.062). The survival benefit of dissection of metastases to the supraclavicular lymph nodes was indicated in patients with thoracic esophageal carcinoma. Supraclavicular nodes appear to be regional nodes similar to other regional nodes. Copyright © 2014 The American Association for Thoracic Surgery. Published by Elsevier Inc. All rights reserved.

    The objectives of this study were to (1) examine the relationship between total trihalomethanes (TTHM) levels in public water supplies and risk of esophageal cancer occurrence and (2) determine whether calcium (Ca) and magnesium (Mg) levels in drinking water modify the effects of TTHM on risk to develop esophageal cancer. A matched case-control study was used to investigate the relationship between the risk of death attributed to esophageal cancer and exposure to TTHM in drinking water in 53 municipalities in Taiwan. All esophageal cancer deaths in the 53 municipalities from 2006 through 2010 were obtained from the Bureau of Vital Statistics of the Taiwan Provincial Department of Health. Controls were deaths from other causes and were pair-matched to the cancer cases by gender, year of birth, and year of death. Each matched control was selected randomly from the set of possible controls for each cancer case. Data on TTHM levels in drinking water were collected from Taiwan Environmental Protection Administration. Information on the levels of Ca and Mg in drinking water was obtained from the Taiwan Water Supply Corporation. The municipality of residence for cancer cases and controls was presumed to be the source of the subject's TTHM, Ca, and Mg exposure via drinking water. Relative to individuals whose TTHM exposure level water with a TTHM exposure ≥4.9 ppb. There was evidence of an interaction between drinking-water TTHM levels and low Ca and Mg intake. Our findings showed that the correlation between TTHM exposure and risk of esophageal cancer development was influenced by Ca and Mg levels in drinking water. This is the first study to report effect modification by Ca and Mg intake from drinking water on the correlation between TTHM exposure and risk of esophageal cancer occurrence. Increased knowledge of the interaction between Ca, Mg, and TTHM in reducing risk of esophageal cancer development will aid in public policymaking and standard setting for drinking

    The aim of this study is to evaluate the reliability, validity, and acceptability of the Chinese version of the EORTC QLQ-OES18 in patients with esophageal cancer. The questionnaire was translated according to the guideline of the EORTC. One hundred and forty-nine patients with esophageal cancer from Tianjin Medical University Cancer Institute and Hospital completed the Karnofsky performance scale (KPS) and the simplified Chinese EORTC QLQ-C30/OES18 scales during July 2013 to January 2014. The results were statistically analyzed by Cronbach's α coefficient, Spearman correlation test with multiple strengthen analysis, and Wilcoxon Rank Sum test. The internal consistency (Cronbach's α coefficient) of all four scales (dysphagia, eating, reflux, and pain) was 0.689-0.822, which were satisfactory or near satisfactory. The absolute values of correlation of each scale between EORTC QLQ-OES18 and EORTC QLQ-C30 were 0.002-0.750 while there was no significant difference between groups divided by KPS scores. We confirmed the Chinese version of EORTC QLQ-OES18 appears to be a reliable, valid, and acceptable instrument for measuring the health-related quality of life of patients with esophageal cancer in mainland China. © The Authors 2017.

    The aim of this study is to confirm the predictive value of controlling nutritional status (CONUT), as a postoperative prognostic marker for esophageal cancer patients undergoing esophagectomy. We retrospectively analyzed 373 patients who underwent three-incision esophagectomy with 2- or 3-field lymphadenectomy for esophageal cancer between April 2005 and March 2016. The patients were divided into three groups based on the degree of preoperative malnutrition as assessed by CONUT: normal, light malnutrition, and moderate or severe malnutrition. The patients with moderate or severe malnutrition experienced a significantly higher frequency of reoperation (normal or light malnutrition, 6.3%; moderate or severe malnutrition, 18.2%; P = 0.033) and a higher tendency for respiratory morbidities (normal or light malnutrition, 14.0%; moderate or severe malnutrition, 27.3%; P = 0.088). Cox regression analysis identified a significantly poor prognosis, in both overall survival (hazard ratio (HR), 3.56; 95% confidence interval (CI), 1.714-7.390; P cancer-specific survival (HR, 3.41; 95% CI, 1.790-6.516; P = 0.046). CONUT is convenient and useful for preoperatively assessing malnutrition and prognosis of esophageal cancer patients who underwent surgery.

    Leventhal's common sense model has provided a useful framework for explaining psychological distress in several chronic illnesses. The model indicates that a person's perception of their illness and their coping strategies are the key determinants of their experience of psychological distress. The present research examines whether illness perceptions and coping strategies are related to levels of psychological distress among survivors of esophageal cancer. Everyone registered with the Oesophageal Patients' Association in the UK was mailed a questionnaire booklet, which included the Illness Perception Questionnaire-Revised, the Cancer Coping Questionnaire, and the Hospital Anxiety and Depression Scale. Complete responses were received from 484 people. Regression models indicated that the variables measured could explain 51% of the variance in anxiety and 42% of the variance in depression. Perceptions of esophageal cancer explained the majority of this variance. Positive focus coping strategies were also found to be important in explaining psychological distress. The results of this study are consistent with previous research demonstrating that illness perceptions are stronger correlates of adaptive outcomes than coping strategies. The findings suggest that cognition-based interventions could potentially be most effective in minimizing emotional distress among survivors of esophageal cancer.

    Objective: To investigate the expressions of cyclin D1 and p27 and DNA content in esophageal cancer and adjacent normal tissues, and to discuss the relationship between them. Methods: The cyclinD1 and p27 were detected by immunohistochemical staining; DNA content was measured by flow cytometry. Results: The positive expression rates of cyclinD1 and p27 in cancer were 45.8% and 33.3% respectively, the DNA content in the positive group of cyclinD1 was higher than that in the negative group of cyclinD1(1.54(0.21 versus 1.08(0.43, P<0.05), while the DNA content and SPF (S-phase fraction) in the positive group of p27 were lower than those in the negative group (1.10(0.19 and 5.56%(5.18% versus 1.66(0.28 and 19.78%(6.12%, P<0.05). Conclusion: The data show that the expression of cyclinD1 and p27 are related to the ontogenesis and progression of esophageal cancer. The combined detection of cyclinD1, p27 and DNA content may be indicators of diagnosis and assessment of esophageal cancer.

    Despite recent advances in surgical technique and treatment strategies for esophageal cancer (EC), to effectively manage the advanced (metastatic or disseminated) and recurrent EC still remain a great challenge. The aim of this study was to determine the feasibility of using intra-esophagus radiofrequency hyperthermia to enhance local HSV-TK/ganciclovir-mediated suicide gene therapy of an innovative animal models with orthotopic esophageal squamous cancers. Human esophageal squamous cancer (ESCa) cells were labeled with lentivirus/luciferase. ESCa cells and nude rats with orthotopic ESCa were divided into in four groups (n = 6/group) and treated with: i) combination therapy of MR imaging-heating-guidewire-mediated radiofrequency hyperthermia ((RFH, 42°C) plus local HSV-TK/GCV; ii) HSV-TK/GCV alone; iii) RFH alone; and (iv) phosphate-buffered saline (PBS). Bioluminescence optical imaging and transcutaneous ultrasound imaging were used to follow up bioluminescence signal and size changes of tumors among different groups over two weeks, which were correlated with subsequent histology. We demonstrated that combination therapy of RFH with gene therapy resulted in the lowest cell proliferation (37.5±8.6%, Pbioluminescence optical imaging photon signal intensity (0.81±0.17, P<0.01) of orthotopic esophageal cancers, compared with groups treated with gene therapy alone, RFH alone and PBS. Our study indicated that intra-esophageal radiofrequency hyperthermia could enhance the HSV-TK-mediated effect on esophageal squamous cancers. PMID:27725910

    The diagnostic capability of using tissue intrinsic micro-Raman signals to obtain biochemical information from human esophageal tissue is presented in this paper. Near-infrared micro-Raman spectroscopy combined with multivariate analysis was applied for discrimination of esophageal cancer tissue from normal tissue samples. Micro-Raman spectroscopy measurements were performed on 54 esophageal cancer tissues and 55 normal tissues in the 400-1750 cm-1 range. The mean Raman spectra showed significant differences between the two groups. Tentative assignments of the Raman bands in the measured tissue spectra suggested some changes in protein structure, a decrease in the relative amount of lactose, and increases in the percentages of tryptophan, collagen and phenylalanine content in esophageal cancer tissue as compared to those of a normal subject. The diagnostic algorithms based on principal component analysis (PCA) and linear discriminate analysis (LDA) achieved a diagnostic sensitivity of 87.0% and specificity of 70.9% for separating cancer from normal esophageal tissue samples. The result demonstrated that near-infrared micro-Raman spectroscopy combined with PCA-LDA analysis could be an effective and sensitive tool for identification of esophageal cancer.

    Full Text Available A 60-year-old man with advanced esophageal cancer was admitted for surgical placement of a feeding jejunostomy tube before commencement of chemoradiotherapy. His esophageal cancer had directly invaded the posterior tracheal wall, inducing a nearly total obstruction of the distal trachea. On the day before the surgery, respiratory failure developed due to tumor progression and tracheal edema. Tracheal intubation and mechanical ventilation were attempted without success. Application of veno-venous extracorporeal membrane oxygenation (ECMO corrected the patient’s respiratory acidosis and relieved his dyspnea. With full ECMO support, he underwent tracheal stent insertion. Two hours later, he was weaned from ECMO support uneventfully. This was a successful case of tracheal stenting for airway obstruction under rescue veno-venous ECMO.

    Chemoradiotherapy (CRT) is widely used as non-surgical treatment for esophageal cancer in recent years. CRT is very useful, but it allows about 40% relapse. Salvage surgery after CRT, long-term survival can be expected, but perioperative mortality is high. In contrast, EMR for local failure after definitive CRT has been reported showing a 5-year survival rate of 49. 1%. If it can safely control of local failure, then we thought it's useful for long-term survival. If the depth of invasion was to the submucosal layer of the local failure lesion, we performed an endoscopic resection. If vertical margins are positive pathologically, we have added a photodynamic therapy. In cases of difficult endoscopic resection, PDT alone was performed. We experienced a case of recurrent esophageal cancer after CRT was useful for local treatment with PDT and EMR.

    We performed thoracoscopic pericardial fenestration for persistent pericardial effusion after radiotherapy for esophageal cancer. An 85-year-old man who had radiation therapy (70.2 Gy) for esophageal cancer was admitted for shortness of breath. Chest computed tomography showed a pericardial effusion. During the 6 months prior to this admission, the patient had undergone percutaneous pericardial drainage 3 times for cardiac tamponade. We performed thoracoscopic partial pericardiectomy with creation of a pleuropericardial window via one access port. Histopathologically, no malignant cells were found in either the resected pericardium or the pericardial effusion. Therefore, we believe the persistent pericardial effusion was secondary to radiotherapy. There was no recurrence of the pericardial effusion for 7 months postoperatively. In summary, thoracoscopic pericardial fenestration is useful in both the diagnosis and treatment of persistent pericardial effusion. (author)

    Full Text Available A 63-year-old man visited the clinic with numbness in the right hand. Magnetic resonance imaging demonstrated multiple low-intensity lesions in the cervical vertebrae and sacrum, which was suspicious of cervical bone metastasis. Fluorodeoxyglucose positron emission tomography/computed tomography revealed areas of increased fluorodeoxyglucose uptake in the thoracic esophagus, sternum and sacrum. A flat, elevated esophageal cancer was identified by upper gastrointestinal endoscopy, and the macroscopic appearance indicated early-stage disease. From the cervical, thoracic and abdominal computed tomography images, there were no metastatic lesions except for the bone lesions. To confirm whether the bone lesions were metastatic, we performed bone biopsy. The histopathological diagnosis was bone marrow hyperplasia. It was crucial for treatment planning to establish whether the lesions were distant metastases. Here, we report a case of esophageal cancer with bone marrow hyperplasia mimicking bone metastasis.

    Full Text Available This study aims to describe the findings from a massive endoscopic screening program in a high-risk area of China and to evaluate the prognosis of patients diagnosed through endoscopic screening compared with those diagnosed at usual hospital visits because of illness.In 2006, an early detection and treatment program was initiated in Yangzhong county, China. Local residents aged 40-69 years were eligible for free endoscopic screening. Endoscopic examination was performed with Lugol's iodine staining, followed by biopsies. Patients diagnosed with esophageal or gastric cancer were referred for treatment and followed to assess their long-term survival status.From 2006 through 2012, we screened 12453 participants, including 5334 (42.8% men and 7119 (57.2% women. The average age was 52.8 ± 8.0 years. We detected 166 patients with upper digestive tract cancers, including 106 cancers in the esophagus (detection rate: 0.85% and 60 cancers in the stomach (detection rate: 0.48%. Of these patients, 98.11% with esophageal cancer and 100% with gastric cancer were defined as at the early stage. In the process of follow-up, 17 patients died from cancer-related causes, and the median survival time was greater than 85 months. The overall survival rates for 1, 3 and 5 years were 98.0%, 90.0% and 89.0%, respectively. A significant positive effect was observed for the long-term survival of patients diagnosed through massive endoscopic screening.In a high-risk population, massive endoscopic screening can identify early stage carcinoma of esophageal and gastric cancers and improve patients' prognosis through early detection and treatment.

    There have been many new developments in our understanding of esophageal carcinoma biology over the past several years. Information regarding both of the major forms of this disease, adenocarcinoma and squamous cell carcinoma, has accumulated in conjunction with data on precursor conditions such as Barrett's esophagus. Interesting and promising findings have included overexpression of proto-oncogenes,loss of heterozygosity at multiple chromosomal loci, tumor suppressor gene inactivation, epigenetic silencing by DNA methylation, and mutations and deletions involving the tumor suppressor gene p53. Important cancer pathways, the cyclin kinase inhibitor cascade and the DNA mismatch repair process, implicated in the genesis of multiple .tumor types have also been inculpated in esophageal carcinogenesis. Alterations in the p16 and p15 cyclin kinase inhibitors including point mutations and homozygous deletions have been reported in primary esophageal tumors. Further developments in the field of molecular carcinogenesis of esophageal malignancies promise to yield improvements in prevention, early detection, prognostic categorization, and perhaps gene-based therapy of this deadly disease.

    This study is aimed to assess the long-term health-related quality of life (HRQL) of patients after esopha gectomy for esophageal cancer in comparison with established norms, and to evaluate changes in HRQL during the different stages of follow-up after esophageal resection. A systematic review was performed by searching medical databases (Medline, Embase and the Cochrane Library) for potentially relevant studies that appeared between January 1975 and March 2011. Studies were included if they addressed the question of HRQL after esophageal resection for esophageal cancer. Two researchers independently performed the study selection, data extraction and analysis processes. Twenty-one observational studies were included with a total of 1282 (12-355) patients. Five studies were performed with short form-36 (SF-36) and 16 with European Organization for Research and Treatment of Cancer (EORTC) QLQ C30 (14 of them also utilized the disease-specific 0ES18 or its previous version OES24).The analysis of long-term generic HRQL with SF-36 showed pooled scores for physical, role and social function after esophagectomy similar to United States norms, but lower pooled scores for physical function, vitality and general health perception. The analysis of HRQL conducted using the Global EORTC C30 global scale during a 6-mo follow-up showed that global scale and physical function were better at the baseline. The symptom scales indicated worsened fatigue, dyspnea and diarrhea 6 mo after esophagectomy. In contrast, however, emotional function had significantly improved after 6 mo. In conclusion, short- and long-term HRQL is deeply affected after esophagectomy for cancer. The impairment of physical function may be a long-term consequence of esophagectomy involving either the respiratory system or the alimentary tract. The short-and long-term improvement in the emotional function of patients who have undergone successful operations may be attributed to the impression that they have

    Full Text Available Introduction: Early diagnosis and appropriate treatment is required in esophageal cancer due to its invasive nature. The aim of this study was to evaluate early post-esophagectomy complications in patients with esophageal cancer who received neoadjuvant chemoradiotherapy (NACR.   Materials and Methods: This randomized clinical trial was carried out between 2009 and 2011. Patients with lower-third esophageal cancer were randomly assigned to one of two groups. The first group consisted of 50 patients receiving standard chemoradiotherapy (Group A and then undergoing surgery, and the second group consisted of 50 patients undergoing surgery only (Group B. Patients were evaluated with respect to age, gender, clinical symptoms, type of pathology, time of surgery, perioperative blood loss, and number of lymph nodes resected as well as early post-operative complicate including leakage at the anastomosis site, chylothorax and pulmonary complications, hospitalization period, and mortality rate within the first 30 days after surgery.   Results: The mean age of patients was 55 years. Seventy-two patients had squamous cell carcinoma (SCC and 28 patients had adenocarcinoma (ACC. There was no significant difference between the two groups with respect to age, gender, time of surgery, complications including anastomotic leakage, chylothorax, pulmonary complications, cardiac complications, deep venous thrombosis (DVT, or mortality. However, there was a significant difference between the two groups regarding hospital stay, time of surgery, perioperative blood loss, and number of lymph nodes resected.   Conclusion:  The use of NACR did not increase early post-operative complications or mortality among patients with esophageal cancer.

    The objective of this study is to compare long-term outcomes between younger and older (70 y and above) esophageal cancer patients treated with curative intent. Overall survival (OS), disease-free survival (DFS), and locoregional recurrence-free interval were compared between older (70 y and above) and younger (below 70 y) esophageal cancer patients treated between 1998 and 2013. Treatment consisted of neoadjuvant chemoradiotherapy with surgery or definitive chemoradiotherapy: 36 to 50.4 Gy in 18 to 28 fractions combined with 5-fluorouracil/cisplatin or carboplatin/paclitaxel. The study comprised 253 patients, of whom 76 were 70 years and older. Median age was 64 years (range, 41 to 83). Most patients had stage II-IIIA disease (83%). Planned treatment was neoadjuvant chemoradiotherapy with surgery for 169 patients (41 patients aged 70 y and older) and definitive chemoradiotherapy for 84 patients (31 patients aged 70 y and older). The compliance to radiotherapy was 92%, with no difference between older and younger patients. In 33 patients (13 patients aged 70 y and older) planned surgery was not performed. Median follow-up was 4.9 years. Three-year OS was 42%. The multivariable analysis showed no statistical difference in OS or in DFS comparing older and younger patients: OS (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.61-1.28), DFS (HR, 0.87; 95% CI, 0.60-1.25). Elderly showed a longer locoregional recurrence-free interval; HR, 0.53 (95% CI, 0.30-0.92; P=0.02) and a higher pathologic complete response rate (50% vs. 25%; P=0.02). Long-term outcomes of older esophageal cancer patients (70 y and above) selected for treatment with neoadjuvant chemoradiotherapy followed by surgery or definitive chemoradiotherapy were comparable with the outcomes of their younger counterparts. Advanced age alone should not be a contraindication for potentially curative chemoradiotherapy-based treatment in esophageal cancer patients.

    AIM: To study the relationship between the expression profiles of a plant-associated human cancer antigen and carcinogenesis of esophagus and its significance. METHODS: We analyzed expression of a plant-associated human cancer antigen in biopsy specimens of normal (n=29),mildly hyperplastic (n=29), mildly (n=30), moderately (n=27)and severely dysplastic (n=29) and malignant esophageal (n=30) tissues by immunohistochemistry. RESULTS: The plant-associated human cancer antigen was mainly confined to the cytoplasm and showed diffuse type of staining. Positive staining was absent or weak in normal (0/30) and mildly hyperplastic tissue samples (2/29), while strong staining was observed in severe dysplasia (23/29) and carcinoma in situ (24/30). There was significant difference of its expression between normal mucosa and severely dysplastic tissues (P<0.001) or carcinoma in situ (P<0.001). Significant difference was also observed between mild dysplasia and severe dysplasia (P<0.001) or carcinomain situ (P<0.001). An overall trend toward increased staining intensity with increasing grade of dysplasia was found. There was a linear correlation between grade of lesions and staining intensity (r=0.794,P<0.001). Samples from esophageal cancer showed no higher levels of expression than those in severely dysplastic lesions (P>0.05). CONCLUSION: The abnormal expression of this plantassociated human cancer antigen in esophageal lesions is a frequent and early finding in the normal-dysplasiacarcinoma sequence in esophageal carcinogenesis. It might contribute to the carcinogenesis of esophageal cancer. The abnormal expression of this plant-associated human cancer antigen in esophageal lesion tissues may serve as a potential new biomarker for early identification of esophageal cancer.

    In recent decades, decreasing trends in esophageal cancer mortality have been observed across China. We here describe esophageal cancer mortality trends in Linzhou city, a high-incidence region of esophageal cancer in China, during 1988-2010 and make a esophageal cancer mortality projection in the period 2011-2020 using a Bayesian approach. Age standardized mortality rates were estimated by direct standardization to the World population structure in 1985. A Bayesian age-period-cohort (BAPC) analysis was carried out in order to investigate the effect of the age, period and birth cohort on esophageal cancer mortality in Linzhou during 1988-2010 and to estimate future trends for the period 2011-2020. Age-adjusted rates for men and women decreased from 1988 to 2005 and changed little thereafter. Risk increased from 30 years of age until the very elderly. Period effects showed little variation in risk throughout 1988-2010. In contrast, a cohort effect showed risk decreased greatly in later cohorts. Forecasting, based on BAPC modeling, resulted in a increasing burden of mortality and a decreasing age standardized mortality rate of esophageal cancer in Linzhou city. The decrease of esophageal cancer mortality risk since the 1930 cohort could be attributable to the improvements of social- economic environment and lifestyle. The standardized mortality rates of esophageal cancer should decrease continually. The effect of aging on the population could explain the increase in esophageal mortality projected for 2020.

    Full Text Available Alterations in arachidonic acid metabolism are involved in human carcinogenesis. Cyclooxygenase (COX and lipoxygenase (LOX are key enzymes in this metabolism. We analyzed the expression of 15S-lipoxygenase-2 (15-LOX-2 mRNA and protein in surgical specimens from normal (N=37 and malignant (63 esophageal tissues using in situ hybridization and immunohistochemistry (IHC, in normal (1, premalignant (1, malignant (5 esophageal cell lines using Northern and Western blotting. 15-LOX-2 was expressed in normal esophageal epithelial cells (EECs at the highest levels, whereas an SV40-immortalized HET-1A line and three of five esophageal cancer cell lines failed to express it at detectable levels. 15-LOX-2 was detected in 76% (28/37 of the normal esophageal mucosae, but only in 46% (29/63 of the cancer specimens using IHC (P<.01. Transient transfection of 15-LOX-2 expression vectors into esophageal cancer cells significantly inhibited the proliferation of 15-LOX-2-negative cancer cells. The COX-2 inhibitor, NS398, induced 15LOX-2 expression in esophageal cancer cells, which is associated with reduced cell viability. This study demonstrated that 15-LOX-2 expression is lost in esophageal cancers and that the induction of 15-LOX-2 can inhibit cancer cell proliferation. Further investigation of the effects of nonsteroidal anti-inflammatory drugs on 15-LOX-2 expression and apoptosis in esophageal cancer cells may be warranted.

    Full Text Available Abstract Background The esophageal cancer related gene 4 (ECRG4 was initially identified and cloned in our laboratory from human normal esophageal epithelium (GenBank accession no.AF325503. ECRG4 was a new tumor suppressor gene in esophageal squamous cell carcinoma (ESCC associated with prognosis. In this study, we investigated the novel tumor-suppressing function of ECRG4 in cancer cell migration, invasion, adhesion and cell cycle regulation in ESCC. Methods Transwell and Boyden chamber experiments were utilized to examined the effects of ECRG4 expression on ESCC cells migration, invasion and adhesion. And flow cytometric analysis was used to observe the impact of ECRG4 expression on cell cycle regulation. Finally, the expression levels of cell cycle regulating proteins p53 and p21 in human ESCC cells transfected with ECRG4 gene were evaluated by Western blotting. Results The restoration of ECRG4 expression in ESCC cells inhibited cancer cells migration and invasion (P P > 0.05. Furthermore, ECRG4 could cause cell cycle G1 phase arrest in ESCC (P Conclusion ECRG4 is a candidate tumor suppressor gene which suppressed tumor cells migration and invasion without affecting cell adhesion ability in ESCC. Furthermore, ECRG4 might cause cell cycle G1 phase block possibly through inducing the increased expression of p53 and p21 proteins in ESCC.

    Preoperative nutritional status may impact surgical outcome and prognosis. We evaluated the predictive value of Onodera's prognostic nutritional index (O's-PNI) of surgical outcome following esophagectomy in esophageal cancer patients. In total, 144 patients undergoing esophagectomy for esophageal cancer from April 2010 to May 2015 were evaluated, retrospectively. Eighty-four patients were enrolled in this study. O's-PNIs were calculated before surgery, discharge, and 1, 2, and 6 mo after discharge. The relationship between O's-PNI and occurrence of complications as classified by the Clavien-Dindo (C-D) classification, length of hospital stay, and survival time was investigated. The mean O's-PNI for patients with complications of more than Grade 2 by the C-D classification was 37.4, which was significantly lower than that for Grades 0 or 1 (40.5, P = 0.0094). A negative correlation was obtained between O's-PNI and hospital stay length (P = 0.0006), whereas a positive correlation was obtained for O's-PNI at 6 mo postsurgery and overall survival (P = 0.0171, P = 0.0201). O's-PNI may represent a useful indicator of the occurrence of complications and length of hospital stay, and may influence overall survival at 6 mo postsurgery. Nutritional management during the perioperative period could therefore contribute to satisfactory outcomes following esophagectomy in esophageal cancer patients.

    Sarcopenia or loss of skeletal muscle mass has been identified as a poor prognostic factor for a wide variety of diseases and conditions. We investigated whether preoperative sarcopenia is associated with postoperative complications in patients undergoing esophagectomy for thoracic esophageal cancer. We retrospectively reviewed the medical records of consecutive patients with thoracic esophageal cancer who underwent esophagectomy between September 2005 and July 2014 at Kyoto University Hospital. Skeletal muscle mass was assessed using preoperative computed tomographic scans by measuring the cross-sectional muscle area at the third lumbar vertebral level. Among the 199 eligible patients, 149 (75%) were classified as having sarcopenia. There was no difference in the incidence of overall complications between the groups (risk ratio [RR]: 1.10, 95% confidence interval [CI]: 0.80-1.53, P = 0.54). However, pulmonary complications were significantly more frequent in the sarcopenia group than in the nonsarcopenia group (RR: 2.63, 95% CI: 1.20-5.77, P = 0.007). Multivariate analyses demonstrated that sarcopenia was associated with a high adjusted risk of one or more pulmonary complications (odds ratio: 2.96, 95% CI: 1.14-7.69, P = 0.026). Sarcopenia independently predicts pulmonary complications after esophagectomy for thoracic esophageal cancer. J. Surg.

    To characterize the two components of theory of mind (ToM) in patients with esophageal cancer combined with depression. Sixty-five patients with esophageal cancer combined with depression (depressed group) and 62 normal controls (control group) were assessed using reading the mind in the eyes test, faux pas task, verbal fluency test, digit span test and WAIS IQ test. The depressed group was divided into two subgroups including psychotic depressed (PD) group (32 cases) and nonpsychotic depressed (NPD) group (33 cases). The clinical symptoms of patients were assessed using Beck depression inventory version II and brief psychiatric reacting scale (BPRS). There was a significant difference between the depressed group and the control group on tasks involving ToM social perceptual components (mind reading: t = 7.39, P mind reading (F = 32.98, P mind reading and faux pas questions (P mind reading: F = 18.99, P mind reading: r = -0.35, P mind reading: r = -0.75, P < 0.01; faux pas questions: r = -0.73, P < 0.01), respectively. The two components of ToM are both impaired in patients with esophageal cancer combined with depression. This indicates that there may be an association between ToM deficits and psychotic symptoms in clinical depression.

    Given the poor prognosis of esophageal cancer and the invasiveness of combined modality treatment, improved prognostic scoring systems are needed. We developed a fuzzy logic-based system to improve the predictive performance of a risk score based on the serum concentrations of C-reactive protein (CRP) and albumin in a cohort of 271 patients with esophageal cancer before radiotherapy. Univariate and multivariate survival analyses were employed to validate the independent prognostic value of the fuzzy risk score. To further compare the predictive performance of the fuzzy risk score with other prognostic scoring systems, time-dependent receiver operating characteristic curve (ROC) analysis was used. Application of fuzzy logic to the serum values of CRP and albumin increased predictive performance for 1-year overall survival (AUC=0.773) compared with that of a single marker (AUC=0.743 and 0.700 for CRP and albumin, respectively), where the AUC denotes the area under curve. This fuzzy logic-based approach also performed consistently better than the Glasgow Prognostic Score (GPS) (AUC=0.745). Thus, application of fuzzy logic to the analysis of serum markers can more accurately predict the outcome for patients with esophageal cancer.

    The development of targeted agents for metastatic esophageal or gastroesophageal junction (GEJ) tumors has been limited when compared with that for other common tumors. To date, the anti-human epidermal growth factor receptor-2 (HER-2) antibody, trastuzumab, in combination with chemotherapy, is the only approved novel agent for these cancers, and its use is limited to the small population of patients whose tumors overexpress HER-2. Despite recent progress in the field, median overall survival remains only 8-12 months for patients with stage IV esophageal or GEJ cancer. In this article, we examine the molecular aberrations thought to drive the development and spread of esophageal cancer and identify promising targets for specific tumor inhibition. Data from clinical studies of targeted agents are reviewed, including epidermal growth factor receptor antibodies, tyrosine kinase inhibitors, HER-2, and vascular endothelial growth factor-directed therapy. Current and future targets include MET, fibroblast growth factor receptor, and immune-based therapies. Evidence from trials to date suggests that molecularly unselected patient cohorts derive minimal benefit from most target-specific agents, suggesting that future collaborative investigation should focus on preselected molecular subgroups of patients with this challenging heterogeneous disease.

    Esophageal cancer is the sixth leading cause of cancer death worldwide. Detection of circulating tumor cells (CTCs) is emerging as a novel strategy for predicting cancer patient prognosis. Here we performed a comprehensive literature search to identify relevant articles in EMbase, PubMed, EBSCO, OVID, Cochrane Database, CNKI, WanFangdata and VIPdata. Meta-analysis was conducted using Stata12.0 software, according to the inclusion and exclusion criteria, extracted data and assessment methodology. Thirteen eligible literature studies were included with a total of 979 esophageal squamous cell carcinoma patients, including 424 CTC-positive and 684 CTC-negative cases. Meta-analysis showed that the presence of CTCs was associated with both worse progression-free/disease-free survival [hazard ration (HR) = 2.32, 95% confidence interval (CI) = 1.57 - 3.43, p < 0.001] and poorer overall survival [HR = 2.64, 95% CI = 1.69 - 4.14, p < 0.001]. Further subgroup analyses demonstrated that CTC-positive patients also showed worse progression-free/disease-free survival and poorer overall survival in different subsets. In summary, our meta-analysis provides strong evidence that detection of CTCs in the peripheral blood is an independent prognostic indicator of poor outcome for esophageal squamous cell carcinoma patients.

    Purpose: To quantitatively evaluate the esophageal cancer response to chemoradiation therapy (CRT) by measuring the esophageal wall thickness in CT. Method: Two datasets were used in this study. The first dataset is composed of CT scans of 15 esophageal cancer patients and 15 normal controls. The second dataset is composed of 20 esophageal cancer patients who underwent PET/CT scans before (Pre-CRT) and after CRT (Post-CRT). We first segmented the esophagus using a multi-atlas-based algorithm. The esophageal wall thickness was then computed, on each slice, as the equivalent circle radius of the segmented esophagus excluding the lumen. To evaluate the changes of wall thickness, we computed the standard deviation (SD), coefficient of variation (COV, SD/Mean), and flatness [(Max–Min)/Mean] of wall thickness along the entire esophagus. Results: For the first dataset, the mean wall thickness of cancer patients and normal controls were 6.35 mm and 6.03 mm, respectively. The mean SD, COV, and flatness of the wall thickness were 2.59, 0.21, and 1.27 for the cancer patients and 1.99, 0.16, and 1.13 for normal controls. Statistically significant differences (p < 0.05) were identified in SD and flatness. For the second dataset, the mean wall thickness of pre-CRT and post-CRT patients was 7.13 mm and 6.84 mm, respectively. The mean SD, COV, and flatness were 1.81, 0.26, and 1.06 for pre-CRT and 1.69, 0.26, and 1.06 for post-CRT. Statistically significant difference was not identified for these measurements. Current results are based on the entire esophagus. We believe significant differences between pre- and post-CRT scans could be obtained, if we conduct the measurements at tumor sites. Conclusion: Results show thicker wall thickness in pre-CRT scans and differences in wall thickness changes between normal and abnormal esophagus. This demonstrated the potential of esophageal wall thickness as a marker in the tumor CRT response evaluation. This work was supported in part by

    Preoperative chemoradiotherapy is the standard of care for locally advanced esophageal cancer, causing persistent deterioration in the nutritional status. We performed a prospective study to evaluate the safety and efficacy of esophageal double-covered self-expandable metal stents in patients with esophageal cancer before chemoradiotherapy. The nutritional status and dysphagia were prospectively recorded. Eleven patients were included: eight were moderate and three were severely malnourished. After stent placement, dysphagia improved in all patients. With regard to complications, one patient developed an esophageal perforation that required urgent esophagectomy. Four patients presented stent migration. Three of these patients required enteral nutrition and none was submitted to surgery because of poor nutritional status. Of the other six patients, only four were operated upon. Stent placement presented a high complication rate and did not prevent weight loss or malnutrition. Other alternatives, including naso-gastric tube placement or endoscopic percutaneous gastrostomy or jejunostomy, should be considered.

    Although serum NY-ESO-1 antibodies (s-NY-ESO-1-Abs) have been reported in patients with esophageal carcinoma, this assay system has not been used to study a large series of patients with various other cancers. Serum samples of 1969 cancer patients [esophageal cancer (n = 172), lung cancer (n = 269), hepatocellular carcinoma (n = 91), prostate cancer (n = 358), gastric cancer (n = 313), colorectal cancer (n = 262), breast cancer (n = 365)] and 74 healthy individuals were analyzed using an originally developed enzyme-linked immunosorbent assay system for s-NY-ESO-1-Abs. The optical density cut-off value, determined as the mean plus three standard deviations for serum samples from the healthy controls, was fixed at 0.165. Conventional tumor markers were also evaluated in patients with esophageal carcinoma. The positive rate of s-NY-ESO-1-Abs in patients with esophageal cancer (31 %) was significantly higher than that in the other groups: patients with lung cancer (13 %), patients with hepatocellular carcinoma (11 %), patients with prostate cancer (10 %), patients with gastric cancer (10 %), patients with colorectal cancer (8 %), patients with breast cancer (7 %), and healthy controls (0 %). The positive rate of s-NY-ESO-1-Abs was comparable to that of serum p53 antibodies (33 %), squamous cell carcinoma antigen (36 %), carcinoembryonic antigen (26 %), and CYFRA 21-1 (18 %) and gradually increased with the tumor stage. The positive rate of s-NY-ESO-1-Abs was significantly higher in patients with esophageal cancer than in patients with the other types of cancers. On the basis of its high specificity and sensitivity, even in patients with stage I tumors, s-NY-ESO-1-Abs may be one of the first choices for esophageal cancer.

    Rhizoma Paridis Saponins (RPS), a natural compound purified from Rhizoma Paridis, has been found to inhibit cancer growth in vitro and in animal models of cancer. However, its effects on esophageal cancer remain unexplored. The purpose of this study was to investigate the effects of RPS on tumor growth in a rat model of esophageal cancer and the molecular mechanism underlying the effects. A rat model of esophageal cancer was established by subcutaneous injection of N-nitrosomethylbenzylamine (NMBA, 1 mg/kg) for 10 weeks. RPS (350 mg/kg or 100 mg/kg) was administered by oral gavage once daily for 24 weeks starting at the first NMBA injection. RPS significantly reduced the size and number of tumors in the esophagus of rats exposed to NMBA and inhibited the viability, migration, and invasion of esophageal cancer cells EC9706 and KYSE150 in a dose dependent manner (all P induced apoptosis and cell cycle G2/M arrest in the esophageal cancer cells. The expression of cyclooxygenases-2 (COX-2) and Cyclin D1 in rat esophageal tissues and the esophageal cancer cells were also significantly reduced by RPS (all P cancer development by promoting apoptosis and cell cycle arrest and inhibiting the COX-2 pathway. RPS might be a promising therapeutic agent for esophageal cancer.

    AIM: To identify alterations in genes and molecular functional pathways in esophageal cancer in a high incidence region of India where there is a widespread use of tobacco and betel quid with fermented areca nuts.METHODS: Total RNA was isolated from tumor and matched normal tissue of 16 patients with esophageal squamous cell carcinoma. Pooled tumor tissue RNA was labeled with Cy3-dUTP and pooled normal tissue RNA was labeled with Cy5-dUTP by direct labeling method.The labeled probes were hybridized with human 10K cDNA chip and expression profiles were analyzed by Genespring GX V 7.3 (Silicon Genetics).RESULTS: Nine hundred twenty three genes were differentially expressed. Of these, 611 genes were upregulated and 312 genes were downregulated. Using stringent criteria (P ≤ 0.05 and ≥ 1.5 fold change),127 differentially expressed genes (87 upregulated and 40 downregulated) were identified in tumor tissue. On the basis of Gene Ontology, four different molecular functional pathways (MAPK pathway,G-protein coupled receptor family, ion transport activity,and serine or threonine kinase activity) were most significantly upregulated and six different molecular functional pathways (structural constituent of ribosome,endopeptidase inhibitor activity, structural constituent of cytoskeleton, antioxidant activity, acyl group transferase activity, eukaryotic translation elongation factor activity)were most significantly downregulated.CONCLUSION: Several genes that showed alterations in our study have also been reported from a high incidence area of esophageal cancer in China. This indicates that molecular profiles of esophageal cancer in these two different geographic locations are highly consistent.

    Purpose: The celiac lymph node axis acts as a gateway for metastatic systemic spread. The need for prophylactic celiac nodal coverage in chemoradiation therapy for esophageal cancer is controversial. Given the improved ability to evaluate lymph node status before treatment via positron emission tomography (PET) and endoscopic ultrasound, we hypothesized that prophylactic celiac node irradiation may not be needed for patients with localized esophageal carcinoma. Methods and Materials: We reviewed the radiation treatment volumes for 131 patients who underwent definitive chemoradiation for esophageal cancer. Patients with celiac lymph node involvement at baseline were excluded. Median radiation dose was 50.4 Gy. The location of all celiac node failures was compared with the radiation treatment plan to determine whether the failures occurred within or outside the radiation treatment field. Results: At a median follow-up time of 52.6 months (95% CI 46.1-56.7 months), 6 of 60 patients (10%) without celiac node coverage had celiac nodal failure; in 5 of these patients, the failures represented the first site of recurrence. Of the 71 patients who had celiac coverage, only 5 patients (7%) had celiac region relapse. In multivariate analyses, having a pretreatment-to-post-treatment change in standardized uptake value on PET >52% (odds ratio [OR] 0.198, p = 0.0327) and having failure in the clinical target volume (OR 10.72, p = 0.001) were associated with risk of celiac region relapse. Of those without celiac coverage, the 6 patients that later developed celiac failure had a worse median overall survival time compared with the other 54 patients who did not fail (median overall survival time: 16.5 months vs. 31.5 months, p = 0.041). Acute and late toxicities were similar in both groups. Conclusions: Although celiac lymph node failures occur in approximately 1 of 10 patients, the lack of effective salvage treatments and subsequent low morbidity may justify prophylactic treatment

    Magnetic-mediated hyperthermia (MMH) is a promising local thermotherapy approach for cancer treatment. The present study investigated the feasibility and effectiveness of MMH in esophageal cancer using a rabbit tumor model. The therapeutic effect of two hyperthermia approaches, magnetic stent hyperthermia (MSH), in which heat is induced by the clinical stent that is placed inside the esophagus, and magnetic fluid hyperthermia (MFH), where magnetic nanoparticles are applied as the agent, was systematically evaluated. A rabbit esophageal tumor model was established by injecting VX2 carcinoma cells into the esophageal submucosa. The esophageal stent was deployed perorally into the tumor segment of the esophagus. For the MFH, magnetic nanoparticles (MNPs) were administered to the rabbits by intratumoral injection. The rabbits were exposed under a benchtop applicator using an alternative magnetic field (AMF) with 300 kHz frequency for the hyperthermia treatment. The results demonstrated that esophageal stents and MNPs had ideal inductive heating properties upon exposure under an AMF of 300 kHz. MSH, using a thermal dose of 46°C with a 10-min treatment time, demonstrated antitumor effects on the rabbit esophageal cancer. However, the rabbit esophageal wall is not heat-resistant. Therefore, a higher temperature or longer treatment time may lead to necrosis of the rabbit esophagus. MFH has a significant antitumor effect by confining the heat within the tumor site without damaging the adjacent normal tissues. The present study indicates that the two hyperthermia procedures have therapeutic effects on esophageal cancer, and that MFH may be more specific than MSH in terms of temperature control during the treatment.

    Many epidemiologic studies indicate a potential association between fruit and vegetable intake and various cancers. The purpose of this meta-analysis is to investigate the association between citrus fruit intake and esophageal cancer risk. The authors conducted a comprehensive search on PubMed, EMBASE, and the Cochrane Library from inception until July 2014. Studies presenting information about citrus intake and esophageal cancer were analyzed. The authors extracted the categories of citrus intake, study-specific odds ratio or relative risk, and the P value and associated 95% confidence intervals for the highest versus lowest dietary intake of citrus fruit level. The association was quantified using meta-analysis of standard errors with a random-effects model. Thirteen case-control studies and 6 cohort studies were eligible for inclusion. Citrus intake may significantly reduce risk of esophageal cancer (summary odds ratio = 0.63; 95% confidence interval = 0.52-0.75; P = 0), without notable publication bias (intercept = -0.79, P = 0.288) and with significant heterogeneity across studies (I = 52%). The results from epidemiologic studies suggest an inverse association between citrus fruit intake and esophageal cancer risk. The significant effect is consistent between case-control and cohort studies. Larger prospective studies with rigorous methodology should be considered to validate the association between citrus fruits and esophageal cancer.

    The high incidence of esophageal cancer in Northeast India and the unique ethnic background and dietary habits provide a great opportunity to study the molecular genetics behind esophageal squamous cell carcinoma in this part of the region. We hypothesized that in addition to currently known environmental risk factors for esophageal cancer, genetic and epigenetic factors are also involved in esophageal carcinogenesis in Northeast India. Therefore, in this study, we explored the possible association between the two important G1 cell cycle regulatory genes p16 and p53 and environmental risk factors and risk of esophageal carcinogenesis. A total of 100 newly diagnosed esophageal cancer cases along with equal number of age-, sex-, and ethnicity-matched controls were included in this study. Methylation-specific polymerase chain reaction was used to determine the p16 promoter methylation status. Single-nucleotide polymorphism at codon 72 of p53 gene was assessed by the polymerase chain reaction-restriction fragment length polymorphism method. Aberrant methylation of p16 gene was seen in 81% of esophageal cancer cases. Hypermethylation of p16 gene was not found in healthy controls. p53 Pro/Pro genotype was found to be a risk genotype in Northeast India compared with Arg/Pro and Arg/Arg. p53 variant/polymorphism was significantly associated with esophageal cancer risk in the study population under all three genetic models, namely, dominant model (Arg/Pro + Pro/Pro vs Arg/Arg odds ratio = 2.25, confidence interval = 1.19-4.26; p = 0.012), recessive model (Arg/Arg + Arg/Pro vs Pro/Pro odds ratio = 2.35, confidence interval = 1.24-4.44; p = 0.008), and homozygous model (Pro/Pro vs Arg/Arg odds ratio = 3.33, confidence interval = 1.54-7.20; p = 0.002). However, p53 variant/polymorphism was not statistically associated with esophageal cancer risk under the heterozygous model (Pro/Pro vs Arg/Pro). In the case-only analysis based on p16

    Esophageal cancer(EC) caused about 395000 deaths in 2010. China has the most cases of EC and EC is the fourth leading cause of cancer death in China. Esophageal squamous cell carcinoma(ESCC) is the predominant histologic type(90%-95%), while the incidence of esophageal adenocarcinoma(EAC) remains extremely low in China. Traditional epidemiological studies have revealed that environmental carcinogens are risk factors for EC. Molecular epidemiological studies revealed that susceptibility to EC is influenced by both environmental and genetic risk factors. Of all the risk factors for EC, some are associated with the risk of ESCC and others with the risk of EAC. However, the details and mechanisms of risk factors involved in the process for EC are unclear. The advanced methods and techniques used in human genome studies bring a great opportunity for researchers to explore and identify the details of those risk factors or susceptibility genes involved inthe process of EC. Human genome epidemiology is a new branch of epidemiology, which leads the epidemiology study from the molecular epidemiology era to the era of genome wide association studies(GWAS). Here we review the epidemiological studies of EC(especially ESCC) in the era of GWAS, and provide an overview of the general risk factors and those genomic variants(genes, SNPs, miRNAs, proteins) involved in the process of ESCC.

    A 66-year-old man with advanced esophageal cancer (staging Mt, 6.0 cm, cT3N0M0, cStage II) was administered neoadjuvant chemotherapy (NAC: 5-fluorouracil and cisplatin). As the tumor continued to grow after one course of NAC, video-assisted thoracoscopic surgery(VATS) was used to perform an esophagectomy along with 3-field lymph node dissection and retrosternal route reconstruction using a gastric tube. The second course of NAC was not administered. Intraoperative findings showed the direct invasion of the primary esophageal cancer into the membranous portion of the left bronchus. The maximum possible tumor tissue was resected and removed. The tumor tissue was exposed extensively to the surface of the esophageal adventitia and a residual tumor at the surface of the left bronchus was suspected. It was diagnosed as CT-pT4 (left bronchus), N0, M0, CT-pStage III. Subsequently, we administered chemoradiotherapy consisting of weekly low-dose docetaxel with radiation for the residual tumor (60 Gy/30 Fr). The patient is still alive 40 months after surgery without any signs of recurrence.

    Esophageal cancer is a mjaor health problems in many parts of the world. A geographical information system (GIS) allows investigation of the geographical distribution of diseases. The purpose of the present study was to explore the relationship between esophageal cancer and effective climatic factors using GIS. The dispersion distribution and the relationship between environmental factors effective on cancer were measured using Arc GIS. The highest degree of spread was in Germi town and the least was in Ardabil city. There was a significant relationship between effective environmental factors and esophageal cancer in Ardabil province. The results indicated that environmental factors probably are influential in determining the incidence of esophageal cancer. Also, these results can be considered as a window to future comprehensive research on esophageal cancer and related risk factors.

    Full Text Available Abstract Background Proton-beam therapy (PBT provides therapeutic advantages over conformal x-ray therapy in sparing organs at risk when treating esophageal cancer because of the fundamental physical dose distribution of the proton-beam. However, cases with extended esophageal lesions are difficult to treat with conventional PBT with a single isocentric field, as the length of the planning target volume (PTV is longer than the available PBT field size in many facilities. In this study, the feasibility of a practical technique to effectively match PBT fields for esophageal cancer with a larger regional field beyond the available PBT field size was investigated. Methods Twenty esophageal cancer patients with a larger regional field than the available PBT single-field size (15 cm in our facility were analyzed. The PTV was divided into two sections to be covered by a single PBT field. Subsequently, each PTV isocenter was aligned in a cranial-caudal (CC axis to rule out any influence by the movement of the treatment couch in anterior-posterior and left-right directions. To obtain the appropriate dose distributions, a designed-seamless irradiation technique (D-SLIT was proposed. This technique requires the following two adjustments: (A blocking a part of the PTV by multi-leaf collimator(s (MLCs; and (B fine-tuning the isocenter distance by the half-width of the MLC leaf (2.5 mm in our facility. After these steps, the inferior border of the cranial field was designed to match the superior border of the caudal field. Dose distributions along the CC axis around the field junction were evaluated by the treatment-planning system. Dose profiles were validated with imaging plates in all cases. Results The average and standard deviation of minimum dose, maximum dose, and dose range between maximum and minimum doses around the field junction by the treatment-planning system were 95.9 ± 3.2%, 105.3 ± 4.1%, and 9.4 ± 5.2%. The dose profile validated by the

    Regulatory regions within the 3' untranslated region (UTR) influence polyadenylation (polyA), translation efficiency, localization and stability of mRNA. Alternative polyA (APA) has been considered to have a key role in gene regulation since 2008. Esophageal carcinoma is the eighth most common type of cancer worldwide. The association between polyA and disease highlights the requirement for comprehensive characterization of genome-wide polyA profiles. In the present study, global polyA profiles were established using the sequencing APA sites (SAPAS) method in order to elucidate the interrelation between 3' UTR length and the development of esophageal cancer. PolyA profiles were analyzed in squamous cell carcinoma, with ~903 genes identified to have shortened 3' UTRs and 917 genes identified to use distal polyA sites. The genes with shortened 3' UTRs were primarily associated with adherens junctions and the cell cycle. Four differentially expressed genes were also found, among which three genes were observed to be upregulated in cancerous tissue and involved in the positive regulation of cell motion, migration and locomotion. One gene was found to be downregulated in cancerous tissue, and associated with oxidative phosphorylation. These findings suggest that esophagitis may have a key role in the development of esophageal carcinoma. Furthermore, the genes with tandem 3' UTRs and differential expression identified in the present study may have the potential to be used as biomarkers for the diagnosis and prognosis of esophageal cancer.

    The growing prevalence of esophageal cancer survivors represent a population typified by an extensive treatment regime, significant postsurgical long-term effects, and a dismal prognosis. Despite this, little is known of the supportive care needs of this patient group and the extent to which these are being met in practice. This review provides a synthesis of the research evidence to date; emphasizing opportunities for clinical application and setting a future agenda with research priorities. A literature search was performed using Medline/Embase, PsycINFO, and Web of Science. Search headings used included; [esophagus] or [esopohageal] or [upper gastrointestinal] or [upper GI] AND [cancer] or [carcinoma] or [squamous cell] AND [supportive care] or [survivorship] or [psychological] or [emotional] or [information] or [social] or [communication] or [spiritual] or [health-related-quality-of-life] or [HRQL] or [qualitative] or [patient narrative] or [clinical nurse specialist] or [CNS]. Related articles in English were reviewed, with additional articles harvested from reference sections. Esophageal cancer survivors report significant late-term effects posttreatment, encompassing sustained impairment in most areas of health-related quality of life. With a necessitated change in eating behavior, survivors find it particularly challenging to adjust to a new social identity and as a cancer population report high levels of psychological morbidity. Although the determinants of psychological morbidity are largely unknown, illness representations may be a key contributor. Several multidisciplinary supportive care interventions have been developed with promising results. The research summarized in this paper provides valuable insight into the psychosocial well-being of the esophageal cancer survivor. However, knowledge gaps remain, alongside a dearth of applied examples in meeting supportive care need. © 2015 International Society for Diseases of the Esophagus.

    BACKGROUND: Health-related quality of life (HRQL) has been studied extensively during the first year following esophagectomy, but little is known about HRQL in long-term survivors. The aim of this study was to investigate HRQL in patients alive at least 1 year after surgical resection for esophageal cancer using validated European Organisation for Research and Treatment of Cancer (EORTC) quality of life (QOL) questionnaires (QLQ). METHODS: Eligible patients, without known disease recurrence and at least 1 year after esophagectomy, were identified from a prospectively maintained database. Patients completed general (QLQ-C30) and esophageal cancer-specific (QLQ-OES18, OG25) questionnaires. A numeric score (0-100) was computed in each conceptual area and compared with validated cancer (n = 1031) and age-matched (n = 7802) healthy populations using two-tailed unpaired t-tests. A cohort of 80 patients had pretreatment scores recorded. RESULTS: Altogether, 132 of 156 eligible patients (84%) completed the self-rated questionnaire, 105 (67.3%) were men, and the mean age was 62 years (range 29-84 years). The mean time since esophagectomy was 70.3 months (12-299 months). Global health status was significantly reduced at least 1 year after esophagectomy (mean +\\/- SD score 48.4 +\\/- 18.6) when compared with patients with esophageal cancer prior to treatment (55.6 +\\/- 24.1) and the general population (71.2 +\\/- 22.4) (p < 0.0001). In a prospective cohort of eighty patients, symptoms related to swallowing difficulty, reflux, pain, and coughing significantly decreased in the long term (p < 0.0001). The degree of subjective swallowing dysfunction was highly correlated with a poor QOL (Spearman\\'s rho = 0.508, p < 0.01). CONCLUSIONS: Global health status remains significantly reduced in long-term survivors after esophagectomy compared with population controls, and swallowing dysfunction is highly associated with this compromised QOL.

    Full Text Available Ngoc Hoang Ha, Richard Hummel, David I WatsonDepartment of Surgery, Flinders University, Flinders Medical Centre, Bedford Park, Adelaide, South Australia, AustraliaAbstract: Barrett’s esophagus is the only known precursor lesion for esophageal adenocarcinoma. Previous studies have shown that a variety of methods can be applied to destroy Barrett’s esophagus epithelium, and healing with a new esophageal squamous epithelium usually occurs following ablation. Radiofrequency ablation (RFA is a relatively new endoscopic technique. It has been claimed that ablation using RFA reduces the risk of cancer progression. RFA is usually easy to apply and is associated with a low risk of morbidity. It achieves complete eradication of (non dysplastic Barrett’s esophagus in most individuals, and the risk of progression to higher grades of dysplasia or cancer is reduced after RFA, although not completely eliminated. Limitations include recurrence of Barrett’s esophagus in up to one-third of individuals, a risk of “buried islands” of Barrett’s esophagus remaining below the regenerated mucosa, and uncertainty about the biological behavior of the new squamous epithelium after RFA. Current evidence supports the use of RFA in individuals with high-grade dysplasia in Barrett’s esophagus, and early stage (T1a intramucosal cancer, and select individuals with low-grade dysplasia. As accurate diagnosis of low-grade dysplasia remains difficult outside expert centers, it is probably premature to recommend routine RFA for all patients diagnosed with low-grade dysplasia in the community, despite the favorable outcomes from one randomized trial. Furthermore, long-term outcomes following ablation remain uncertain, and ongoing endoscopy surveillance is still required after RFA as progression to cancer remains a possibility. Outcomes from large studies with long-term follow-up are needed to definitively confirm that RFA ablation can reliably prevent cancer

  7. ICAM1 Is a Potential Cancer Stem Cell Marker of Esophageal Squamous Cell Carcinoma.

    Full Text Available Esophageal squamous cell carcinoma (ESCC accounts for about 90% of esophageal cancer diagnosed in Asian countries, with its incidence on the rise. Cancer stem cell (CSC; also known as tumor-initiating cells, TIC is inherently resistant to cytotoxic chemotherapy and radiation and associates with poor prognosis and therapy failure. Targeting therapy against cancer stem cell has emerged as a potential therapeutic approach to develop effective regimens. However, the suitable CSC marker of ESCC for identification and targeting is still limited. In this study, we screened the novel CSC membrane protein markers using two distinct stemness characteristics of cancer cell lines by a comparative approach. After the validation of RT-PCR, qPCR and western blot analyses, intercellular adhesion molecule 1 (ICAM1 was identified as a potential CSC marker of ESCC. ICAM1 promotes cancer cell migration, invasion as well as increasing mesenchymal marker expression and attenuating epithelial marker expression. In addition, ICAM1 contributes to CSC properties, including sphere formation, drug resistance, and tumorigenesis in mouse xenotransplantation model. Based on the analysis of ICAM1-regulated proteins, we speculated that ICAM1 regulates CSC properties partly through an ICAM1-PTTG1IP-p53-DNMT1 pathway. Moreover, we observed that ICAM1 and CD44 could have a compensation effect on maintaining the stemness characteristics of ESCC, suggesting that the combination of multi-targeting therapies should be under serious consideration to acquire a more potent therapeutic effect on CSC of ESCC.

    The precise incidence rates of multiple primary colorectal cancers in esophageal cancer patients are unknown. In total, 480 consecutive patients with esophageal cancers surgically resected in the Kumamoto University Hospital received preoperative total colonoscopy for the assessment of colorectal disease between April 2005 and February 2016. We retrospectively investigated the occurrence of synchronous colorectal cancer with esophageal cancer. In addition, we examined the risk factors for the incidence of multiple primary colorectal cancers. Of the 480 patients, 14 (2.9 %) had synchronous colorectal cancers, 13 had well-differentiated tubular adenocarcinomas, and 1 had papillary adenocarcinoma. Other 14 patients had metachronous colorectal cancer. The current incidence rates of synchronous and total (both synchronous and metachronous) colorectal cancers outnumbered those in normal healthy population and those in esophageal cancer patients which previously reported by The Japan Esophageal Society. The age ≥70 years (hazard ratio 4.82, 95 % confidence interval 1.473-15.78; p = 0.009) and Brinkman index ≥800 (hazard ratio 3.47, 95 % confidence interval 1.056-11.37; p = 0.040) were the independent risk factors for the incidence of synchronous colorectal cancer. They were also the independent risk factors for the incidence of total colorectal cancer. The results of the present study suggested that pretreatment screening with total colonoscopy is meaningful for patients with esophageal cancer, because the frequency of synchronous colorectal cancer was not negligible. Particularly, in patients >70 years and with history of heavy smoking, pretreatment colonoscopy might be necessary.

    During thoracic cavity operations, it is difficult to obtain sufficient working space and good operative field visibility in patients with pectus excavatum because the space between the vertebral bodies and sternum is very narrow. Here, we report the successful treatment of esophageal cancer in a patient with pectus excavatum. A 77-year-old man with esophageal cancer was referred to our hospital for further treatment. He was diagnosed with multiple early esophageal squamous cell carcinomas. The patient had pectus excavatum, but because it was asymptomatic, a video-assisted thoracoscopic radical esophagectomy in the left lateral decubitus position without pectus excavatum repair was selected. Despite the patient's unusual anatomy, video-assisted thoracoscopic esophagectomy in the left decubitus position allowed for good operative field visibility, as the videoscope was inserted from the side of the diaphragm. This operative procedure is useful in patients with esophageal cancer who also have pectus excavatum. To the best of our knowledge, this is the second report of video-assisted thoracoscopic esophagectomy in an esophageal cancer patient with pectus excavatum.

    It has been well documented that the diagnosis of cancer is psychologically devastating to both the patients and caregivers. The incidence and mortality of esophageal cancer were 20.85 and 16.24 per 100,000 persons and the sixth most commonly diagnosed cancer and the fourth main cause of cancer death in China. We surveyed patients-caregivers dyad and examined the determinants of their depression and hopelessness. The prevalence of depression among patients and caregivers was 52.8% and 47.2%, and the prevalence for hopelessness was 64.4% and 53.9%, respectively Regression models indicate that the variables measured could explain 58.9% and 51.7% of the variance in depression and 66.8% and 45.7% of the variance in hopelessness among patients and caregivers, respectively. Overall, hopelessness was a determinant of depression and vice versa to both patients and caregivers. Esophageal patients' depression and hopelessness could also affect caregivers' depression and hopelessness despite the social support that family caregivers have. Psychosocial interventions should be planned to both Chinese patients and caregivers considering the predictors found in this study. Copyright © 2013 John Wiley & Sons, Ltd.

    Objective: To explore the systemic and local cellular immune function of patients with esophageal carcinoma or cardiac cancer. Methods: The distribution of tumor-infiltrating lymphocyte (TIL) and cancer-associated macrophage (TAM) in local tumor tissues of 52 patients with esophageal cancer or cardiac cancer were observed by immunehistochemical method. The level of peripheral SIL-2R and TNF-α of preoperative and postoperative 1, 2, 3 weeks were detected by ELISA and ABC-ELISA methods respectively, then the acquired results were compared with 30 cases of normal control group. Results:The peritumor inifltration densities of TIL and TAM was greater than that of cancer nest stroma (P<0.05). Compared with the normal control group, the levels of sIL-2R and TNF-α increased signiifcantly (P<0.01). Immune function could be suppressed by operative wound in a short time of post-operation, whose damage severity was closely associated with tumor TNM stages. Conclusion: Patients with esophageal or cardiac cancer have cellular immune function disorders. Dynamic testing of peripheral sIL-2R and TNT-α level in patients with esophageal or cardiac cancer has positive clinical signiifcance in the evaluation of cellular immune function, tumor lesion degree and curative effect.

    The north-western region of China carries a big burden of esophageal cancer with incidence above the national average. This study ascertained the association between fruit and vegetable consumption and the risk of esophageal cancer in this remote part of China. A case-control study was undertaken in Urumqi and Shihezi, Xinjiang Uyghur Autonomous Region of China, between 2008 and 2009. Participants were 359 incident esophageal cancer patients and 380 hospital-based controls. Information on habitual fruit and vegetable consumption was obtained by face-to-face interview using a validated semiquantitative food frequency questionnaire. Unconditional logistic regression analyses were performed to assess the strength of the associations. The esophageal cancer patients consumed significantly less fruits (mean 364.3, standard deviation [SD] 497.4 g) and vegetables (mean 711.4, SD 727.9 g) daily than their counterparts without the disease (mean 496.5, SD 634.4 g and mean 894.5, SD 746.1 g, respectively). The adjusted odds ratios were 0.48 (95% confidence interval 0.33-0.71) and 0.46 (95% confidence interval 0.32-0.68) for consuming at least 515 g of fruits and 940 g of vegetables per day, respectively, relative to at most 170 g and 520 g. With respect to nutrients contained in fruits and vegetables, intakes of vitamin C, vitamin E, β-cryptoxanthin, potassium, and magnesium at high levels also reduced the esophageal cancer risk. In conclusion, inverse associations were evident between consumption of fruits and vegetables and the risk of esophageal cancer for adults residing in north-west China.

However, there is no consensus regarding delineation of the nodal clinical target volume (CTVn, especially for lower cervical lymph nodes. This study aimed to map the location of metastatic supraclavicular lymph nodes in thoracic esophageal carcinoma patients with supraclavicular node involvement and generate an atlas to delineate the CTVn for elective nodal radiation of esophageal squamous cell carcinoma. Patients and methods: In this study, the supraclavicular regional lymph node was further divided into four subgroups. The locations of the involved supraclavicular nodes for all patients were then transferred onto a template computed tomography (CT image. A volume probability map was then generated with nodal volumes, and was displayed on the template CT to provide a visual impression of nodal frequencies and anatomic distribution. Results: We identified 154 supraclavicular nodal metastases based on CT image in 96 patients. Of these, 29.2% were located in group I region, 59.7% in group II region, 10.4% in group III region, and 0.7% in group IV region. Conclusion: On the basis of our study, we suggest that the appropriate radiation field of CTVn should include the group I and II regions and the CTVn exterior margin along the lateral side of the internal jugular vein may be suitable.

    Objective To investigate the effects of bisdemethoxycurcumin (BDMC) on non-small cell lung cancer (NSCLC) cell line, A549, and the highly metastatic lung cancer 95D cells. Methods CCK-8 assay was used to assess the effect of BDMC on cytotoxicity. Flow cytometry was used to evaluate apoptosis. Western blot analysis, electron microscopy, and quantification of GFP-LC3 punctuates were used to test the effect of BDMC on autophagy and apoptosis of lung cancer cells. Results BDMC inhibited the viability of NSCLC cells, but had no cytotoxic effects on lung small airway epithelial cells (SAECs). The apoptotic cell death induced by BDMC was accompanied with the induction of autophagy in NSCLC cells. Blockage of autophagy by the autophagy inhibitor 3-methyladenine (3-MA) repressed the growth inhibitory effects and induction of apoptosis by BDMC. In addition, BDMC treatment significantly decreased smoothened (SMO) and the transcription factor glioma-associated oncogene 1 (Gli1) expression. Furthermore, depletion of Gli1 by siRNA and cyclopamine (a specific SMO inhibitor) induced autophagy. Conclusion Aberrant activation of Hedgehog (Hh) signaling has been implicated in several human cancers, including lung cancers. The present findings provide direct evidence that BDMC-induced autophagy plays a pro-death role in NSCLC, in part, by inhibiting Hedgehog signaling.

    Purpose: To identify germline polymorphisms to predict concurrent chemoradiation therapy (CCRT) response in esophageal cancer patients. Materials and Methods: A total of 139 esophageal cancer patients treated with CCRT (cisplatin-based chemotherapy combined with 40 Gy of irradiation) and subsequent esophagectomy were recruited at the National Taiwan University Hospital between 1997 and 2008. After excluding confounding factors (i.e., females and patients aged {>=}70 years), 116 patients were enrolled to identify single nucleotide polymorphisms (SNPs) associated with specific CCRT responses. Genotyping arrays and mass spectrometry were used sequentially to determine germline polymorphisms from blood samples. These polymorphisms remain stable throughout disease progression, unlike somatic mutations from tumor tissues. Two-stage design and additive genetic models were adopted in this study. Results: From the 26 SNPs identified in the first stage, 2 SNPs were found to be significantly associated with CCRT response in the second stage. Single nucleotide polymorphism rs16863886, located between SGPP2 and FARSB on chromosome 2q36.1, was significantly associated with a 3.93-fold increase in pathologic complete response to CCRT (95% confidence interval 1.62-10.30) under additive models. Single nucleotide polymorphism rs4954256, located in ZRANB3 on chromosome 2q21.3, was associated with a 3.93-fold increase in pathologic complete response to CCRT (95% confidence interval 1.57-10.87). The predictive accuracy for CCRT response was 71.59% with these two SNPs combined. Conclusions: This is the first study to identify germline polymorphisms with a high accuracy for predicting CCRT response in the treatment of esophageal cancer.

    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. 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. 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 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. 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.

    Background Older patients are commonly excluded from clinical trials in esophageal and gastroesophageal junction (gej) cancer. High-level evidence to guide management in this group is lacking. In the present study, we compared outcomes and described tolerance for curative- and noncurative-intent treatments among patients 70 years of age and older. Methods We retrospectively reviewed all patients 70 years of age and older diagnosed with localized esophageal and gej cancer at our centre between 2005 and 2012. Results The 74 patients identified had a median age of 77 years. Of those patients, 62% received curative-intent treatment, consisting mostly of concomitant chemoradiation therapy (n = 43, 93%). Median overall survival for patients receiving curative-intent treatment was 18.6 months [95% confidence interval (ci): 13.0 to 28.0 months], with 23% being long-term survivors (95% ci: 11.3% to 36.7%). In contrast, patients receiving noncurative-intent treatment had a median overall survival of 8.8 months (95% ci: 6.7 to 11.9 months), with none being long-term survivors (p dysphagia was seen after curative (81%) or palliative radiotherapy (78%) in symptomatic patients, and toxicities were manageable. The odds of not receiving curative treatment was higher by a factor of 8.5 among patients 80 years of age or older compared with those 70–79 years of age (95% ci: 2.5 to 28.7). Conclusions In managing older patients with esophageal and gej cancer, curative-intent treatment (compared with noncurative-intent treatment) leads to a significant survival benefit with a reasonable toxicity profile. Informed counselling of patients and their families about a curative treatment approach and efforts to increase awareness among oncology care providers are suggested. PMID:26715880

Therefore, 60 cases could be evaluated, and then divided into combined group (given Endostar+DP plan and single chemotherapy group, 30 cases in each group. The level of VEGF, tumor size and CT perfusion (CTP parameters, including blood flow (BF, blood volume (BV, mean transit time (MTT, and permeability surface (PS before and after treatment were determined for comparison. Kaplan-Merier method was used to analyze the overall survival (OS of 2 groups.Results: The efficacy of combined group was superior to single chemotherapy group. The level of vascular endothelial growth factor (VEGF in combined group was obviously lower than that in single chemotherapy group after treatment (P<0.01. Compared with treatment before in combined group, BF, BV and PS decreased while MTT increased after treatment (P<0.05. However, there were no significant differences in single chemotherapygroup before and after treatment (P>0.05. The median OS was 30 months (95%CI: 20.935-39.065 for combined group and 21 months (95%CI: 15.109-26.591 for single chemotherapy group, respectively (P=0.048. The 1-, 2- and 3-year survival rates were 86.2%, 59.3% and 36.6% in combined group, and 70.8%, 32.1% and 17.8% in single chemotherapy group, respectively.Conclusion: Endostar can down-regulate the expression of VEGF, improve the state of hypertransfusion and high permeability of tumor vessels, has better curative effect without slighter adverse reactions, and prolong the survival time of patients with advanced esophageal cancer when combined with chemotherapy.

    Patients with esophageal cancer experience chronic dysphagia. This condition typically necessitates the use of a jejunal feeding tube to provide the patient with adequate nutrition. Obstruction of the jejunal feeding tube is common in clinical practice and results in malnutrition in most patients and mortality in the most serious cases. An analysis of the status of jejunostomy-tube use in our unit found that these tubes were obstructed in 27.6% of the cases. The causes of this obstruction were: tube bending due to tight suturing, small inner-tube diameter, the absence of adequate jejunal-feeding standards, and failure to implement relevant training strategies. These findings motivated us to attempt to reduce the incidence of jejunostomy-tube obstruction at our center. This project was designed to reduce the incidence of jejunostomy-tube obstruction in esophageal cancer patients from 27.6% to ≤ 3%. Clear strategies, including modification of the stitching method used at the implantation end of the central venous catheter-type jejunostomy tube, establishment of feeding standards, creation of educational guidelines and leaflets, classroom teaching, and technical examinations, were used to reduce the prevalence of obstruction incidents. The jejunostomy-tube obstruction rate was reduced from 27.6% to 6.7%. While the study objective was not achieved, the magnitude of the reduction was still significant at 75.7%. Cross-disciplinary collaboration, continuous education and training, and the promotion of standards of practice were used to significantly reduce the jejunostomy tube obstruction rate in esophageal cancer patients. This result substantially increased the nutrition and quality of care received by this patient population.

    Objective: To observe the clinical outcomes of Endostar combined with DP regimen for treating advanced esophageal cancer. Methods: A total of 62 patients with advanced esophageal cancer admitted from May, 2011 to May, 2013 were enrolled for a prospective, randomized controlled trial and 2 cases were excluded from the study because ofⅣ degree of digestive tract reaction and myelosuppression. Therefore, 60 cases could be evaluated, and then divided into combined group (given Endostar+DP plan) and single chemotherapy group, 30 cases in each group. The level of VEGF, tumor size and CT perfusion (CTP) parameters, including blood flow (BF), blood volume (BV), mean transit time (MTT), and permeability surface (PS) before and after treatment were determined for comparison. Kaplan-Merier method was used to analyze the overall survival (OS) of 2 groups. Results:The efifcacy of combined group was superior to single chemotherapy group. The level of vascular endothelial growth factor (VEGF) in combined group was obviously lower than that in single chemotherapy group after treatment (P0.05). The median OS was 30 months (95%CI: 20.935-39.065) for combined group and 21 months (95%CI: 15.109-26.591) for single chemotherapy group, respectively (P=0.048). The 1-, 2- and 3-year survival rates were 86.2%, 59.3% and 36.6% in combined group, and 70.8%, 32.1% and 17.8% in single chemotherapy group, respectively. Conclusion: Endostar can down-regulate the expression of VEGF, improve the state of hypertransfusion and high permeability of tumor vessels, has better curative effect without slighter adverse reactions, and prolong the survival time of patients with advanced esophageal cancer when combined with chemotherapy.

    To evaluate treatment outcomes and determine prognostic factors in patients with esophageal cancer treated with esophagectomy after neoadjuvant chemoradiotherapy (NCRT). We retrospectively evaluated 39 patients with esophageal cancer who underwent concurrent chemoradiotherapy followed by esophagectomy between 2002 and 2012. Initial clinical stages of patients were stage IB in 1 patient (2.6%), stage II in 5 patients (12.9%), and stage III in 33 patients (84.6%). The median age of all the patients was 62 years, and the median follow-up period was 17 months. The 3-year overall survival (OS) rate was 33.6% in all the patients. The 3-year locoregional recurrence-free survival (LRFS) rate was 33.7%. In multivariate analysis with covariates of age, the Eastern Cooperative Oncology Group performance status, hypertension, diabetes mellitus, tumor length, clinical response, clinical stage, pathological response, pathological stage, lymphovascular invasion, surgical type, and radiotherapy to surgery interval, only pathological stage was an independent significant prognostic factor affecting both OS and LRFS. The complications in postoperative day 90 were pneumonia in 9 patients, anastomotic site leakage in 3 patients, and anastomotic site stricture in 2 patients. Postoperative 30-day mortality rate was 10.3% (4/39); the cause of death among these 4 patients was respiratory failure in 3 patients and myocardial infarction in one patient. Only pathological stage was an independent prognostic factor for both OS and LRFS in patients with esophageal cancer treated with esophagectomy after NCRT. We could confirm the significant role of NCRT in downstaging the initial tumor bulk and thus resulting in better survival of patients who gained earlier pathological stage after NCRT.

    A 72-year-old male with a chief complaint of dysphagia was admitted to our hospital. Upper gastrointestinal endoscopic examination showed double cancers with thoracic esophageal cancer in the middle esophagus and gastric cancer in the antrum. Pathological examinations of the double cancer revealed the first one to be moderately-differentiated squamous cell carcinoma and the second to be well-differentiated adenocarcinoma. Computed tomography (CT) of the chest and abdomen showed no distant or lymph node metastases. Clinical stagings of the double cancer were stage II (T2N0M0)in esophageal cancer and stage I A (T1N0M0) in gastric cancer. The patient received neoadjuvant chemotherapy using docetaxel, CDDP and 5-FU. After 2 courses of chemotherapy, the adverse event was grade 2 in leucopenia and grade 2 in alopecia. Repeated macroscopic and histological examinations after chemotherapy revealed that the esophageal cancer had significant reductions in the size of tumors, leading to a partial response, and the gastric cancer had disappeared, leading to a complete response. He underwent thoracoscopy-assisted esophagectomy in the prone position, and laparoscopy-assisted gastric tube reconstruction. This neoadjuvant chemotherapy of docetaxel, CDDP and 5-FU might be effective and tolerable as with patients with double cancer of esophageal and gastric cancers.

    Full Text Available BACKGROUND: To evaluate the risk and sites of metachronous secondary primary malignancies (SPMs among patients with esophageal cancer. METHODS: Newly diagnosed esophageal cancer patients between 1997 and 2011 were recruited. To avoid surveillance bias, SPMs that developed within one year were excluded. Standardized incidence ratios (SIRs of metachronous SPMs in these patients were calculated by comparing to the cancer incidence in the general population. Risk factors for SPM development, included age, sex, comorbidities and cancer-related treatments, were estimated by Cox proportional hazards models. RESULTS: During the 15-year study period, 870 SPMs developed among 18,026 esophageal cancer patients, with a follow-up of 27,056 person-years. The SIR for all cancers was 3.53. The SIR of follow-up period ≥ 10 years was 3.56; 5-10 years, 3.14; and 1-5 years, 3.06. The cancer SIRs of head and neck (15.83, stomach (3.30, lung and mediastinum (2.10, kidney (2.24 and leukemia (2.72, were significantly increased. Multivariate analysis showed that age ≥ 60 years (hazard ratio [HR] 0.74, being male (HR 1.46 and liver cirrhosis (HR 1.46 were independent factors. According to the treatments, major surgery (HR 1.24 increased the risk, but chemotherapy was nearly significant. CONCLUSIONS: Patients with esophageal cancer were at increased risk of developing metachronous SPMs. The SIR remained high in follow-up > 10 years, so that close monitoring may be needed for early detection of SPM among these esophageal cancer patients.

    Natural and synthetic triterpenoids have been shown to kill cancer cells via multiple mechanisms. The therapeutic effect and underlying mechanism of the synthetic triterpenoid bardoxolone methyl (C-28 methyl ester of 2-cyano-3,12-dioxoolean-1,9-dien-28-oic acid; CDDO-Me) on esophageal cancer are unclear. Herein, we aimed to investigate the anticancer effects and underlying mechanisms of CDDO-Me in human esophageal squamous cell carcinoma (ESCC) cells. Our study showed that CDDO-Me suppressed the proliferation and arrested cells in G2/M phase, and induced apoptosis in human ESCC Ec109 and KYSE70 cells. The G2/M arrest was accompanied with upregulated p21Waf1/Cip1 and p53 expression. CDDO-Me significantly decreased B-cell lymphoma-extra large (Bcl-xl), B-cell lymphoma 2 (Bcl-2), cleaved caspase-9, and cleaved poly ADP ribose polymerase (PARP) levels but increased the expression level of Bcl-2-associated X (Bax). Furthermore, CDDO-Me induced autophagy in both Ec109 and KYSE70 cells via suppression of the phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway. There were interactions between the autophagic and apoptotic pathways in Ec109 and KYSE70 cells subject to CDDO-Me treatment. CDDO-Me also scavenged reactive oxygen species through activation of the nuclear factor (erythroid-derived 2)-related factor 2 (Nrf2) pathway in Ec109 and KYSE70 cells. CDDO-Me inhibited cell invasion, epithelial-mesenchymal transition, and stemness in Ec109 and KYSE70 cells. CDDO-Me significantly downregulated E-cadherin but upregulated Snail, Slug, and zinc finger E-box-binding homeobox 1 (TCF-8/ZEB1) in Ec109 and KYSE70 cells. CDDO-Me significantly decreased the expression of octamer-4, sex determining region Y-box 2 (Sox-2), Nanog, and B lymphoma Mo-MLV insertion region 1 homolog (Bmi-1), all markers of cancer cell stemness, in Ec109 and KYSE70 cells. Taken together, these results indicate that CDDO-Me is a promising anticancer agent

    Full Text Available Abstract Background Secondary radiation-induced cancers are rare but well-documented as long-term side effects of radiation in large populations of breast cancer survivors. Multiple neoplasms are rare. We report a case of esophageal adenocarcinoma in a patient treated previously for breast cancer and clear cell carcinoma of the kidney. Case presentation A 56 year-old non smoking woman, with no alcohol intake and no familial history of cancer; followed in the National Institute of Oncology of Rabat Morocco since 1999 for breast carcinoma, presented on consultation on January 2011 with dysphagia. Breast cancer was treated with modified radical mastectomy, 6 courses of chemotherapy based on CMF regimen and radiotherapy to breast, inner mammary chain and to pelvis as castration. Less than a year later, a renal right mass was discovered incidentally. Enlarged nephrectomy realized and showed renal cell carcinoma. A local and metastatic breast cancer recurrence occurred in 2007. Patient had 2 lines of chemotherapy and 2 lines of hormonotherapy with Letrozole and Tamoxifen assuring a stable disease. On January 2011, the patient presented dysphagia. Oesogastric endoscopy showed middle esophagus stenosing mass. Biopsy revealed adenocarcinoma. No evidence of metastasis was noticed on computed tomography and breast disease was controlled. Palliative brachytherapy to esophagus was delivered. Patient presented dysphagia due to progressive disease 4 months later. Jejunostomy was proposed but the patient refused any treatment. She died on July 2011. Conclusion We present here a multiple neoplasm in a patient with no known family history of cancers. Esophageal carcinoma is most likely induced by radiation. However the presence of a third malignancy suggests the presence of genetic disorders.

  12. Identification of differentially expressed genes in esophageal cancer through SSH in com- bination with high throughput reverse Northern screening

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    To understand the molecular mechanisms of carcinogenesis of esophagus and to isolate genes with different expression levels in esophageal cancer, suppression subtractive hybridization (SSH) was combined with PCR-based cDNA synthesis and reverse Northern on the cancer tissues and matched almost normal mucosa using 5 microgram of total RNA as starting marterial. Eight genes were found expressed differentially in esophageal cancer, in which 5 were known genes and 3 were novel ones; and 6 were down-regulated in cancer tissues, while 2 were up-regulated; 6 were of mid-high abundance and 2 were of low abundance in esophagus. The results revealed that alteration in expression level of multiple genes underlied the initiation and development of esophageal cancer. The differentially expressed genes identified in this study such as liporcotinⅠ, cystatin A, cystatin B, cytokeratin 13 may play roles in dedifferentiation, transformation and malignant proliferation of esophageal cancer. The combination of SSH with PCR-based double- strand cDNA synthesis and high throughput reverse Northern screening is an efficient way to isolate differentially expressed genes from microgram of total RNA.

    Highlights: • MiR-146b promotes esophageal cancer cell proliferation. • MiR-146b inhibits esophageal cancer cell apoptosis. • C/EBPβ directly binds to miR-146b promoter conserved region. • MiR-146b is up-regulated by C/EBPβ LAP2 transcriptional activation. - Abstract: Recent clinical study indicated that up-regulation of miR-146b was associated with poor overall survival of patients in esophageal squamous cell carcinoma. However, the underlying mechanism of miR-146b dysregulation remains to be explored. Here we report that miR-146b promotes cell proliferation and inhibits cell apoptosis in esophageal cancer cell lines. Mechanismly, two C/EBPβ binding motifs are located in the miR-146b promoter conserved region. Among the three isoforms of C/EBPβ, C/EBPβ LAP2 positively regulated miR-146b expression and increases miR-146b levels in a dose-dependent manner through transcription activation of miR-146b gene. Together, these results suggest a miR-146b regulatory mechanism involving C/EBPβ, which may contribute to the up-regulation of miR-146b in esophageal squamous cell carcinoma.

    The purpose of this report is to communicate the use of single-positron emission computed tomography scan in planning radiation treatments for patients with a history of radiation to the thoracic cavity. A patient presented with obstructive esophageal cancer, having previously received chemotherapy and radiation therapy to the mediastinum for non-Hodgkin lymphoma 11 years earlier. Owing to a number of comorbidities, the patient was not a surgical candidate and was referred to the University of Washington Medical Center for radiation therapy. Prior dose to the spinal cord and lung were taken into account before designing the radiation treatment plan.

  15. Potential diagnostic value of serum p53 antibody for detecting esophageal cancer: a meta-analysis.

    Directory of Open Access Journals (Sweden)

    Jun Zhang

    Full Text Available BACKGROUND: Mutant p53 protein overexpression has been reported to induce serum antibodies against p53. Various studies assessing the diagnostic value of serum p53 antibody in patients with esophageal cancer remain controversial. This study aims to comprehensively and quantitatively summarize the potential diagnostic value of serum p53 antibody in esophageal cancer. METHODS: We systematically searched PubMed and Embase until 31st May 2012, without language restriction. Studies were assessed for quality using QUADAS (quality assessment of studies of diagnostic accuracy. Positive likelihood ratio (PLR and negative likelihood ratio (NLR were pooled separately and compared with overall accuracy measures diagnostic odds ratio (DOR and symmetric summary receiver operating characteristic (sROC. The PLR and NLR and their 95% confidence interval (CI were calculated using a fixed effects model according to the Mantel-Haensed method and random effects model based on the work of Der Simonian and laird, respectively. RESULTS: Fifteen studies (cases = 1079, controls = 2260 met the inclusion criteria for the meta-analysis. Approximately 53.33% (8/15 of the included studies were of high quality (QUADAS score≥8, which were retrospective case-control studies. The summary estimates for quantitative analysis of serum p53 antibody in the diagnosis of esophageal cancer were PLR 6.95 (95% CI: 4.77-9.51, NLR 0.75 (95%CI: 0.72-0.78 and DOR 9.65 (95%CI: 7.04-13.22. However, we found significant heterogeneity between NLRs. CONCLUSIONS: The current evidence suggests serum p53 antibody has a potential diagnostic value for esophageal cancer. However, its discrimination power is not perfect because of low sensitivity. IMPACT: These results suggest that s-p53-antibody may be useful for monitoring residual tumor cells and for aiding in the selection of candidates for less invasive treatment procedures because of the high specificity of s-p53-antibody.

    Thoracoscopic esophagectomy is only established in some centers and affords a cervical anastomosis because intrathoracic anastomosis as a routine is technically too difficult. Laparoscopic mobilisation of the stomach (gastrolysis) is an important contribution for minimal invasive surgery of esophageal cancer.This procedure reduces the stress of the two cavity operation for the patient and allows the construction of a comparable gastric conduit like by open surgery. The technique of laparoscopic gastrolysis as preparation for transthoracic en bloc esophagectomy is described in detail and preliminary results are briefly mentioned.

    We aim to compare the outcomes of patients undergoing R0 esophagectomy by a multidisciplinary team (MDT) with outcomes after surgery alone performed by surgeons working independently in a UK cancer unit. An historical control group of 77 consecutive patients diagnosed with esophageal cancer and undergoing surgery with curative intent by six general surgeons between 1991 and 1997 (54 R0 esophagectomies) were compared with a group of 67 consecutive patients managed by the MDT between 1998 and 2003 (53 R0 esophagectomies, 26 patients received multimodal therapy). The proportion of patients undergoing open and closed laparotomy and thoracotomy decreased from 21% and 5%, respectively, in control patients, to 13% and 0% in MDT patients (chi2 = 11.90, DF = 1, P = 0.001; chi2 = 5.45, DF = 1, P = 0.02 respectively). MDT patients had lower operative mortality (5.7%vs. 26%; chi2 = 8.22, DF = 1, P = 0.004) than control patients, and were more likely to survive 5 years (52%vs. 10%, chi2 = 15.05, P = 0.0001). In a multivariate analysis, MDT management (HR = 0.337, 95% CI = 0.201-0.564, P team management and surgical subspecialization improved outcomes after surgery significantly for patients diagnosed with esophageal cancer.

    Berberine is an isoquinoline alkaloid found in several plant species like famous chinese herb, Rhizoma coptidis which has been used locally as a strong gastrointestinal remedy for thousands of years. The inhibitory effects of berberine on tumor progression properties have been reported before. In this study, we investigated the effect of berberine on an esophageal cancer cell line, KYSE-30 with emphasis on its effects on the expression of certain chemokine receptors. The cytotoxic effect of berberine on KYSE-30 cells was analyzed by MTT assay. In vitro cell migration assay was also applied to the treated cells and the expression levels of the selected chemokine receptors (CXCR4 and CCR7) was measured at mRNA level. A retarded growth, associated with increasing concentrations of berberine, was obvious. On the other hand, the migration rate of the cells was decreased when they were treated with different concentrations of berberine and the expression levels of the two chemokine receptors, involved in the migration and metastasis of esophageal cancer cells, were decreased following the same treatments. With these results, we tend to conclude that berberine might be a proper candidate for further investigations, by targeting the chemokine receptors, and possible applications as anti-metastatic agent in cancer studies.

    A 51-year-old male patient with esophageal cancer and cervical, thoracic and celiac artery lymph node metastases was treated by combination chemotherapy of TS-1 and cisplatin. TS-1 (80 mg/m2/day) was administered for 14 days followed by 14 days rest as 1 course. Cisplatin (70 mg/m2/day) was administered in 24-hour continuous intravenous infusion at day 8 after the start of TS-1. Before treatment, the tumor marker, CEA showed 27,060 ng/ml. After 5 courses of chemotherapy, endoscopy revealed that the primary tumor had disappeared and no cancer cells were detected by endoscopic biopsy. Chest and abdominal CT scan also showed almost total disappearance of the lymph nodes metastases. CEA decreased to 710 ng/ml. No high-grade toxicities (WHO grade 3 or 4) were seen during the chemotherapy. He is now very well. This TS-1/cisplatin chemotherapy regimen might be a useful treatment for metastatic esophageal cancer.

    1983-11-01

    A study was made of 74 patients with esophageal and cardiac cancer, Stages 3 and 4. The excretion of catecholamines, corticosteroids and their precursors was studied, tests with adrenalin before and after preoperative irradiation at a summary dose of 30 Gy were done. It has been shown that before the start of radiation therapy the excretion of catecholamines and corticosteroids is lowered, the reaction to adrenalin administration is negative in most patients, the phase syndrome of cardiac hypodynamics associated with disturbed function of the sympathoadrenal system was revealed. Preoperative irradiation in patients with esophageal and cardiac cancer results in an increased excretion of 17-ketosteroids (17-KS) and 17-ketogenic steroids, however 17-KS excretion does not reach the normal level. For better tolerance of irradiation and for a radiosensitization effect testenate is administered to patients before and during radiation therapy. The administration of testenate 7-10 days before the start and during radiotherapy proved to be effective which was confirmed by noticeable necrobiotic and necrotic changes of cancer cells.

    An analysis of the results of treatment of 344 patients with cancer of the thoracic part of the esophagus was performed. Out of those, 104 received surgical and combined treatment and 240 (inoperable cancer) were given radiotherapy alone or in combination with local hyperthermia, general chemotherapy or intratumoral iontophoresis of chemotherapeutic agents. The operation after Dobromyslov-Torek proved to be insufficient in most of surgical cases because there were metastatic lesions below the diaphragm. Local hyperthermia potentiated the effect of radiation treatment. The early results of treatment improved after intratumoral sarcolysin ionophoresis was used in conjunction with radiation therapy.

    Full Text Available OBJECTIVE: To assess the reliability of magnetic resonance imaging (MRI for detection of esophageal cancer in the Levrat model of end-to-side esophagojejunostomy. BACKGROUND: The Levrat model has proven utility in terms of its ability to replicate Barrett's carcinogenesis by inducing gastroduodenoesophageal reflux (GDER. Due to lack of data on the utility of non-invasive methods for detection of esophageal cancer, treatment efficacy studies have been limited, as adenocarcinoma histology has only been validated post-mortem. It would therefore be of great value if the validity and reliability of MRI could be established in this setting. METHODS: Chronic GDER reflux was induced in 19 male Sprague-Dawley rats using the modified Levrat model. At 40 weeks post-surgery, all animals underwent endoscopy, MRI scanning, and post-mortem histological analysis of the esophagus and anastomosis. With post-mortem histology serving as the gold standard, assessment of presence of esophageal cancer was made by five esophageal specialists and five radiologists on endoscopy and MRI, respectively. RESULTS: The accuracy of MRI and endoscopic analysis to correctly identify cancer vs. no cancer was 85.3% and 50.5%, respectively. ROC curves demonstrated that MRI rating had an AUC of 0.966 (p<0.001 and endoscopy rating had an AUC of 0.534 (p = 0.804. The sensitivity and specificity of MRI for identifying cancer vs. no-cancer was 89.1% and 80% respectively, as compared to 45.5% and 57.5% for endoscopy. False positive rates of MRI and endoscopy were 20% and 42.5%, respectively. CONCLUSIONS: MRI is a more reliable diagnostic method than endoscopy in the Levrat model. The non-invasiveness of the tool and its potential to volumetrically quantify the size and number of tumors likely makes it even more useful in evaluating novel agents and their efficacy in treatment studies of esophageal cancer.

    Preoperative nutritional supplementation, management of esophageal leaks, and postoperative anastomotic strictures still remain common problems in the management of esophageal cancer. Jejunal feeding tubes, total parenteral nutrition (TPN) with nasogastric suction, and repeated esophageal dilations remain the most common treatments, respectively. The aim of this study was to evaluate the use of removable silicone stents in (1) the preoperative nutritional optimization during neoadjuvant therapy, (2) the management of perioperative anastomotic leak, and (3) the management of postoperative anastomotic strictures. Review of our prospectively maintained esophageal database identified 15 patients who had removable self-expanding silicone stents placed in the management of one of these three management problems from July 2004 to August 2006. Preoperative therapy: Five patients underwent initial stent placement in preparation for neoadjuvant therapy. Dysphagia relief was seen in 100% of patients, with optimal caloric needs taken within 24 h of placement. All patients tolerated neoadjuvant therapy without delay from dehydration or malnutrition. One stent migration was found at the time of operation, which was removed without sequelae. Perioperative therapy: Five patients developed delayed (>10 days) esophageal leaks that were managed with removable esophageal stent and percutaneous drainage (in three patients). All patients had successful exclusion of the leak on the day of the procedure with resumption of oral intake on the evening of procedure. All five healed leaks without sequelae. Postoperative therapy: Five patients developed postoperative anastomotic strictures that required dilation and placement of removable esophageal stent. The median number of dilations was 1 (range 1-2), with all stents placed for approximate 3 months duration. All patients had immediate dysphagia relief after stent placement. Removable esophageal stents are novel treatment option to optimize

    LKB1 is a tumor susceptibility gene for the Peutz-Jeghers cancer syndrome and is a target for mutational inactivation in sporadic human malignancies. LKB1 encodes a serine/threonine kinase that has critical roles in cell growth, polarity and metabolism. A novel and important function of LKB1 is its ability to regulate the phosphorylation of CREB-regulated transcription co-activators (CRTCs) whose aberrant activation is linked with oncogenic activities. However, the roles and mechanisms of LKB1 and CRTC in the pathogenesis of esophageal cancer have not been previously investigated. In this study, we observed altered LKB1-CRTC signaling in a subset of human esophageal cancer cell lines and patient samples. LKB1 negatively regulates esophageal cancer cell migration and invasion in vitro. Mechanistically, we determined that CRTC signaling becomes activated because of LKB1 loss, which results in the transcriptional activation of specific downstream targets including LYPD3, a critical mediator for LKB1 loss-of-function. Our data indicate that de-regulated LKB1-CRTC signaling might represent a crucial mechanism for esophageal cancer progression.

    Background and study aims: Multiple squamous cell carcinomas (SCCs) frequently arise in the upper aerodigestive tract, referred to as the field cancerization phenomenon. The aim of this study was to elucidate the detailed clinical features of second primary head and neck (H&N) SCCs arising in patients with esophageal SCC. Patients and methods: A total of 818 patients underwent endoscopic resection for superficial esophageal cancer between January 2006 and December 2013. Of these, 439 patients met our inclusion criteria, and we retrospectively investigated the incidence, primary sites, and stages of second primary H&N SCCs in these patients. Results: A total of 53 metachronous H&N SCCs developed in 40 patients after a median follow-up period of 46 months (range 9 – 109). The cumulative incidence rates of metachronous H&N SCCs at 3, 5, and 7 years were 5.3 %, 9.7 %, and 17.2 %, respectively. These lesions were frequently located at pyriform sinus or in the posterior wall of the pharynx (70 %, 37/53 lesions). Most of the lesions were detected at an early stage, though 4 lesions were associated with lymph node metastasis when their primary sites were detected (1 postcricoid area, 2 posterior wall of hypopharynx, and 1 lateral wall of oropharynx). Conclusions: Patients with esophageal SCC should undergo careful inspection of the pyriform sinus and posterior wall of the pharynx for detection of H&N SCCs. Methods to open the hypopharyngeal space, such as the Valsalva maneuver, should be included in the surveillance program. PMID:27556090

    Background Angiopoietin-2 (Ang-2) is one of the critical regulators of tumor angiogenesis. Studies have shown a significant correlation of Ang-2 expression to tumor invasion and metastasis in various human cancers, but little is known about the serum Ang-2 (sAng-2) levels in esophageal squamous cell cancer (ESCC) and its precursors. In this study, we aimed to investigate its role in screening for ESCC and its precursors.Methods We carried out a free endoscopic screening in Feicheng City, a high ESCC incidence area in Shandong Province of China. Serum samples were collected as follows: 91 from normal subjects, 44 from patients with esophagitis,85 from patients with hyperplasia, and 13 from patients with early ESCC. In addition, 28 serum samples were obtained from patients with invasive ESCC undergoing surgery in People's Hospital of Feicheng City. All the subjects of the five groups were diagnosed by histopathology. The sAng-2 levels were tested and compared, and the diagnostic power in early or/and invasive ESCC was calculated in terms of sensitivity and other parameters.Results The sAng-2 levels were (22.0±5.5), (21.3±3.2), (20.5±3.3), (24.0±5.0), and (29.8±5.0) U/ml in normal,esophagitis, hyperplasia, early ESCC, and invasive ESCC groups respectively. It was significantly higher in early ESCC than inhyperplasia group (P=0.009). The invasive ESCC group showed the highest Ang-2 level among all groups (all P=0.000). The sensitivities of sAng-2 to early and invasive ESCC were 23.1% and 78.6% respectively.Conclusion sAng-2 level is related to carcinogenesis and progression of ESCC, but it can not be used to screen for early ESCC.

    AIM:To determine the functional significance of TC21 in esophageal squamous cell carcinoma (ESCC).METHODS:TC21 siRNA transfection was carried out using Hyperfectamine to knock down TC21,and transcripts were analyzed by reverse transcription-polymerase chain reaction and protein by Western blotting.We demonstrated the effect of TC21 downregulation of cell signaling in esophageal cancer cells by assessing the phosphorylation status of its downstream targets,phosphoinositide 3-kinase (PI3K),phosphatase and tensin homolog (PTEN),protein kinase B (pAkt),nuclear factor-κB (NF-κB) and cyclinD1 using specific antibodies.Cell survival analysis after cisplatin treatment was carried out by cell viability assay and cell cycle analysis using flow cytometry.RESULTS:TC21 knockdown in human ESCC cell line TE13 cells,showed only a marginal increase (14.2%) in cell death compared with control cells.The expressions of the signaling proteins PI3K and pAkt,transcription factor NF-κB,and cell cycle protein cyclin D1 were markedly decreased in response to TC21 downregulation,whereas the level of pPTEN,an antagonist of PI3K,was increased.In addition,we evaluated the potential of TC21 as a putative target for sensitizing ESCC cells to the chemotherapeutic agent dsplatin.Increased cell death (38.4%) was observed in cells treated with cisplatin after TC21 knockdown compared with cells which were treated with cisplatin alone (20% cell death).CONCLUSION:Results suggest that TC21 mediates its effects via the PI3K-Akt pathway,NF-κB and cydin D1,and enhances chemoresistance in esophageal cancer cells.

    Full Text Available Esophageal candidiasis is the most common opportunistic infection in patients with altered immunity such as Human Immunodeficiency Virus (HIV infection, cancer patients on chemotherapy and radiotherapy. Neutropenia, irradiation and chemotherapy will facilitate deeper mucosal invasion leading to esophageal candidiasis. Empirical treatment of esophageal candidiasis without antifungal susceptibility testing will lead to the emergence of drug resistant species increasing the morbidity and mortality associated with cancer. The present study aimed to study the frequency of esophageal candida in individuals with cancer, species level identification and antifungal susceptibility pattern. Scrapings of whitish appearing lesions were obtained from a total of thirty five cases of endoscopically identified esophageal candidiasis were obtained from cancer patients. Identification of the Candida isolates were done by cultivation in Sabouraud dextrose agar (SDA, Gram staining, germ tube test, colony morphology in Chrom agar and corn meal agar, sugar assimilation and fermentation tests. Antifungal susceptibility was done by Microbroth dilution method for Fluconazole, Itraconazole and Amphotericin B. We found that Candida albicans was the predominant species isolated followed by Candida tropicalis and Candida glabrata. Sensitivity rates were 94%, 96% and 100% for Fluconazole, Itraconazole and Amphotericin B. Species level identification of Candida isolated from esophageal candidiasis and their antifungal sensitivity testing should be performed for early identification of resistant strains and for promptly treating the cases there by preventing the dissemination of infection in case of immune-compromised individuals. Further the susceptibility pattern will facilitate therapeutic guidance especially in individuals prone to relapse. [J Med Allied Sci 2016; 6(1: 29-34

    Objectives To conduct a systematic review and meta-analysis of studies comparing the gastric-tube vs. whole-stomach for esophageal cancer in order to determine the optimal surgical technique of esophagectomy. Methods A comprehensive literature search was performed using PubMed, EMBASE, ScienceDirect, Ovid MEDLINE, Cochrane Library, Web of Science, Google Scholar, and Scopus. Clinical trials that compared the gastric-tube versus whole-stomach for esophageal cancer were selected. The clinical endpoints included anastomotic leakage, anastomotic stenosis, reflux esophagitis, pneumonia, delayed gastric emptying, and thoracic stomach syndrome. Results A total of 6 articles (1571 patients) were included. Compared to the whole-stomach approach, the gastric-tube approach was associated with a lower incidence of reflux esophagitis (95% confidence interval [CI]: 0.16 to 0.81, p = 0.01) and thoracic stomach syndrome (95% CI: 0.17 to 0.55, p < 0.0001). The rates of anastomotic leakage, anastomotic stenosis, pneumonia, and delayed gastric emptying did not significantly differ between the two groups. Conclusions The gastric-tube esophagectomy is superior to the whole-stomach approach, as it is associated with a lower incidence of postoperative reflux esophagitis and thoracic stomach syndrome. Our findings must be validated in large-scale randomized controlled trials. PMID:28267808

    To identify the risk factors of esophageal cancer and study their effect on the survival rates patients of Jammu region, India. Detailed information was collected on socio-demographic, dietary and clinico-pathological parameters for 200 case control pairs. Discrete (categorical) data of 2 independent groups (control and cases) were summarized in frequency (%) and compared by using Chi-square (χ2 ) test. The mean age of two independent groups was compared by independent Student's t-test. To find out potential risk factor (s), the variable (s) found significant in univariate analysis were further subjected to multivariate logistic regression analysis. The association of potential risk factors with patients survival (3-year overall survival) was done by Kaplan-Meier survival curve analysis using Log-rank test. A 2-tailed (a = 2) P food (OR = 1.77, 95% CI = 1.10-2.85) and red chilly (OR = 1.76, 95% CI = 1.07-2.89). Probability of survival lowered significantly (P factor of esophageal cancer in Jammu region, followed by the salt tea, smoking and the sundried food.

    Full Text Available We examined esophageal cancer patients who received enteral nutrition (EN to evaluate the validity of early EN compared to delayed EN, and to determine the appropriate time to start EN. A total of 208 esophagectomy patients who received EN postoperatively were divided into three groups (Group 1, 2 and 3 based on whether they received EN within 48 h, 48 h–72 h or more than 72 h, respectively. The postoperative complications, length of hospital stay (LOH, days for first fecal passage, cost of hospitalization, and the difference in serum albumin values between pre-operation and post-operation were all recorded. The statistical analyses were performed using the t-test, the Mann-Whitney U test and the chi square test. Statistical significance was defined as p < 0.05. Group 1 had the lowest thoracic drainage volume, the earliest first fecal passage, and the lowest LOH and hospitalization expenses of the three groups. The incidence of pneumonia was by far the highest in Group 3 (p = 0.019. Finally, all the postoperative outcomes of nutritional conditions were the worst by a significant margin in Group 3. It is therefore safe and valid to start early enteral nutrition within 48 h for postoperative esophageal cancer patients.

    For cancer risk assessment in astronauts and for countermeasure development, it is essential to understand the molecular mechanisms of radiation carcinogenesis and how these mechanisms are influenced by exposure to the types of radiation found in space. We are developing an in vitro model system for the study of radiation-induced initiation and progression of esophageal carcinoma. Development of squamous cell carcinoma of the esophagus is associated with radiation exposure, as revealed by the significant enhanced in incidence rates for this type of cancer in the survivors of the atomic bomb detonations in Japan. It is also associated with poor nutritional status and micronutrient deficiencies, which are also important issues for long duration spaceflight. The possible synergies between nutritional issues and radiation exposure are unknown. Here we present the results of preliminary characterization of both normal and hTERT-immortalized esophageal epithelial cells grown in 2-dimensional culture. We analyzed DNA repair capacity by measuring the kinetics of formation and loss of gamma-H2AX foci following radiation exposure. Additionally, we analyzed induction of chromosomal aberrations using 3-color fluorescence in situ hybridization (FISH). Data were generated using both low LET (gamma rays) and high LET ions (1000 MeV/nucleon iron.

    More than 4000 cases of esophagus neoplasms are diagnosed every year in France. Radiotherapy, which can be delivered in preoperative or exclusive with a concomitant chemotherapy, plays a central role in treatment of esophagus cancer. Even if efficacy of radiotherapy no longer has to be proved, the prognosis of esophagus cancer remains unfortunately poor with a high recurrence rate. Toxicity of esophageal radiotherapy is correlated with the irradiation volume, and limits dose escalation and local control. Esophagus is a deep thoracic organ, which undergoes cardiac and respiratory motion, making the radiotherapy delivery more difficult and increasing the planning target volume margins. Definition of accurate planning target volume margins, taking into account the esophagus' intrafraction motion and set up margins is very important to be sure to cover the clinical target volume and restrains acute and late radiotoxicity. In this article, based on a review of the literature, we propose planning target volume margins adapted to esophageal radiotherapy.

    Emerging data suggests a benefit for using intensity modulated radiation therapy (IMRT) for the management of esophageal cancer. We retrospectively reviewed patients treated at our institution who received definitive or preoperative chemoradiation with either IMRT or 3D conformal radiation therapy (3DCRT) between October 2000 and January 2012. Kaplan Meier analysis and the Cox proportional hazard model were used to evaluate survival outcomes. We evaluated a total of 232 patients (138 IMRT, 94 3DCRT) who received a median dose of 50.4 Gy (range, 44-64.8) to gross disease. Median follow up for all patients, IMRT patients alone, and 3DCRT patients alone was 18.5 (range, 2.5-124.2), 16.5 (range, 3-59), and 25.9 months (range, 2.5-124.2), respectively. We observed no significant difference based on radiation technique (3DCRT vs. IMRT) with respect to median overall survival (OS) (median 29 vs. 32 months; P = 0.74) or median relapse free survival (median 20 vs. 25 months; P = 0.66). On multivariable analysis (MVA), surgical resection resulted in improved OS (HR 0.444; P 20% weight loss (OR 0.51; P = 0.050). Our data suggest that while IMRT-based chemoradiation for esophageal cancer does not impact survival there was significantly less toxicity. In the IMRT group there was significant decrease in weight loss and grade ≥3 toxicity compared to 3DCRT.

    The establishment of a database has been suggested in order to collect, organize, and distribute genetic information about esophageal cancer. The World Organization for Specialized Studies on Diseases of the Esophagus and the Human Variome Project will be in charge of a central database of information about esophageal cancer-related variations from publications, databases, and laboratories; in addition to genetic details, clinical parameters will also be included. The aim will be to get all the central players in research, clinical, and commercial laboratories to contribute. The database will follow established recommendations and guidelines. The database will require a team of dedicated curators with different backgrounds. Numerous layers of systematics will be applied to facilitate computational analyses. The data items will be extensively integrated with other information sources. The database will be distributed as open access to ensure exchange of the data with other databases. Variations will be reported in relation to reference sequences on three levels--DNA, RNA, and protein-whenever applicable. In the first phase, the database will concentrate on genetic variations including both somatic and germline variations for susceptibility genes. Additional types of information can be integrated at a later stage.

    To summarize the evidence about the association between red and processed meat intake and the risk of esophageal cancer, we systematically searched the PubMed and EMBASE databases up to May 2012, with a restriction to English publications, and the references of the retrieved articles. We combined the study-specific relative risks (RRs) and 95%CI, comparing the highest with the lowest categories of consumption by using a random-effects model. A total of 4 cohort studies and 23 case-control studies were included in the meta-analysis. The combined RRs (95%CI) of the cohort studies comparing the highest and lowest categories were 1.26 (1.00-1.59) for red meat and 1.25 (0.83-1.86) for processed meat. For the case-control studies, the combined RRs (95%CI) comparing the highest and lowest categories were 1.44 (1.16-1.80) for red meat and 1.36 (1.07-1.74) for processed meat. Findings from this meta-analysis suggest that a higher consumption of red meat was associated with a greater risk of esophageal cancer.

    Esophageal cancer (EC) is one of the most common malignant tumors around the world and has a high incidence in China. Chinese EC patients account for more than 50% in the world. The pathological subtype of EC shows a geographic distribution. Adenocarcinoma is the main pathological type in western countries, while squamous cell carcinoma is the dominant subtype in China. Thus specific diagnosis and treatment of EC are needed for Chinese patients. Although early diagnosis, progress in surgery and comprehensive treatment of EC have made remarkable achievements in China in recent years, yet the prognosis for resectable EC patients remains poor, with a 5-year survival of 30%. In addition, as the level of treatment varies significantly in different regions and centers around China, the current status of treatment for EC needs further improvement. This article reviews the advances in the treatment for EC in recent years, analyzes the present problems, and explores the perspective of the progress in esophageal cancer treatment in the era of precision medicine.

    Severity and frequency of late complications were investigated in long-surviving patients who had received radiotherapy for esophageal cancer from 1980 to 1989. Ten patients who had survived more than 5 years were studied. Pathologically, squamous cell carcinoma was demonstrated in all 10 patients, which involved 8 males and 2 females aged 51 to 86 years (average, 69). The exposure dose was 70 Gy/35-38 fr/7-7.5 w in patients with external irradiation alone and 54-64 Gy/27-32 fr/5.5-6.5 w externally and 6-16 Gy/2-5 fr/2-3 w internally in patients with external and intracavitary irradiation. Stenosis appeared from 4 to 40 months after radiotherapy in 9 of the 10 patients, and 2 patients developed fistulas. There were 4 patients with serious complications requiring surgical treatment (severe stenosis in 3 patients and fistula with lung abscess in 1 patient). For patients treated with external and intracavitary brachytherapy, the severity of late complications increased when the total dose including both external and intracavitary irradiation exceeded 70 Gy. To determine an appropriate therapeutic dose for esophageal cancer is extremely difficult, and a strict, long-term follow-up procedure must be performed along with appropriate treatment. (author).

    Nanoparticles, such as gold nanoparticles (GNP), upon convenient modifications perform multi tasks catering to many biomedical applications. However, GNP or any other type of nanoparticles is yet to achieve the feat of intracellular regulation of endogenous genes of choice such as through manipulation of a gene-promoter in a chromosome. As for gene modulation and delivery, GNP (or other nanoparticles) showed only limited gene therapy potential, which relied on the delivery of `exogenous' genes invoking gene knockdown or replacement. Practically, there are no instances for the nanoparticle-mediated promoter regulation of `endogenous' genes, more so, as a cancer selective phenomenon. In this regard, we report the development of a simple, easily modifiable GNP-formulation, which promoted/up-regulated the expression of a specific category of `endogenous' genes, the glucocorticoid responsive genes. This genetic up-regulation was induced in only cancer cells by modified GNP-mediated transcriptional activation of its cytoplasmic receptor, glucocorticoid receptor (GR). Normal cells and their GR remained primarily unperturbed by this GNP-formulation. The most potent gene up-regulating GNP-formulation down-regulated a cancer-specific proliferative signal, phospho-Akt in cancer cells, which accompanied retardation of tumor growth in the murine melanoma model. We show that GR-targeted GNPs may find potential use in the targeting and modulation of genetic information in cancer towards developing novel anticancer therapeutics.Nanoparticles, such as gold nanoparticles (GNP), upon convenient modifications perform multi tasks catering to many biomedical applications.

    MicroRNAs (abbreviated miRNAs) have been demonstrated to be involved in tumorigenesis and cancer development and proposed as promising biomarkers in cancer diagnosis. Numerous studies have observed the aberrant expression of miRNAs in esophageal cancer. However, there are some discrepant results. Thus, we conducted this meta-analysis to identify the overall accuracy of miRNAs in the diagnosis of esophageal cancer. A comprehensive literature search was conducted in PubMed and other databases using combinations of key words. The summary receiver operator characteristic curves were plotted to assess the overall diagnostic performance of miRNAs. Chi-squared and I(2) tests were used to assess the heterogeneity between studies. Additionally, we conducted subgroup and sensitivity analyses to analyze the potential sources of heterogeneity. In total, 33 studies from 12 articles were available in this meta-analysis. The pooled sensitivity, specificity, positive and negative likelihood ratio (PLR, NLR) diagnostic odds ratio, and area under the curve were 0.80, 0.80, 4.0, 0.25, 16, and 0.87, respectively. Subgroup analyses based on the sample types (saliva-, serum- and plasma-based) showed no differences in the diagnostic accuracy of each subgroup. An independent meta-analysis of eight articles was conducted to evaluate the diagnostic accuracy of miRNAs in patients with esophageal squamous cell carcinoma, with a pooled sensitivity of 0.77, specificity of 0.83, PLR of 4.4, NLR of 0.27, diagnostic odds ratio of 16, and area under the curve of 0.87. In conclusion, this meta-analysis demonstrates the feasibility of using miRNAs as non-invasive biomarkers to discriminate esophageal cancer from healthy controls. However, further high-quality studies on more clearly defined esophageal cancer patient are needed to confirm our conclusion. © 2015 International Society for Diseases of the Esophagus.

    High Glasgow Prognostic scores (GPSs) have been associated with poor outcomes in various tumors, but the values of GPS and modified GPS (mGPS) in patients with advanced esophageal cancer receiving chemoradiotherapy (CRT) has not yet been reported. We have evaluated these with respect to predicting responsiveness to CRT and long-term survival. Between January 2002 and December 2011, tumor responses in 142 esophageal cancer patients (131 men and 11 women) with stage III (A, B and C) and IV receiving CRT were assessed. We assessed the value of the GPS as a predictor of a response to definitive CRT and also as a prognostic indicator in patients with esophageal cancer receiving CRT. We found that independent predictors of CRT responsiveness were Eastern Cooperative Oncology Group (ECOG) performance status, GPS and cTNM stage. Independent prognostic factors were ECOG performance status and GPS for progression-free survival and ECOG performance status, GPS and cTNM stage IV for disease-specific survival. GPS may be a novel predictor of CRT responsiveness and a prognostic indicator for progression-free and disease-specific survival in patients with advanced esophageal cancer. However, a multicenter study as same regime with large number of patients will be needed to confirm these outcomes. © 2015 International Society for Diseases of the Esophagus.

    Esophageal cancer is the eighth most common cancer in the world and has an extremely dismal prognosis, with a 5-year survival of less than 20%. Current treatment options are limited, and thus identifying new molecular targets and pathways is critical to derive novel therapies. Worldwide, more than 90% of esophageal cancers are esophageal squamous cell cancer (ESCC). Previously, we identified that Krüppel-like factor 5 (KLF5), a key transcriptional regulator normally expressed in esophageal squamous epithelial cells, is lost in human ESCC. To examine the effects of restoring KLF5 in ESCC, we transduced the human ESCC cell lines TE7 and TE15, both of which lack KLF5 expression, with retrovirus to express KLF5 upon doxycycline induction. When KLF5 was induced, ESCC cells demonstrated increased apoptosis and decreased viability, with up-regulation of the proapoptotic factor BAX. Interestingly, c-Jun N-terminal kinase (JNK) signaling, an important upstream mediator of proapoptotic pathways including BAX, was also activated following KLF5 induction. KLF5 activation of JNK signaling was mediated by KLF5 transactivation of two key upstream regulators of the JNK pathway, ASK1 and MKK4, and inhibition of JNK blocked apoptosis and normalized cell survival following KLF5 induction. Thus, restoring KLF5 in ESCC cells promotes apoptosis and decreases cell survival in a JNK-dependent manner, providing a potential therapeutic target for human ESCC.

    @@INTRODUCTION The esophageal carcinoma is a common malignant tumor in Linzhou City (Linxian) of Henan Province in northern China. Although the etiology and natural history of esophageal carcinoma are not clear, a substantial amount of evidence has been provided to suggest that the development of human esophageal squamous cell carcinomas (SCC) is a multistage progressive process[1-4] An early indicator of abnormality in persons predisposed to esophageal SCC is an increased proliferation of esophageal epithelial cells,morphologically manifested as basal cell hyperplasia (BCH), and dysplasia (DYS), and carcinoma in situ, which could be considered precancerous lesions of esophageal SCC[1-4].

    Epidemiological data regarding tea and coffee consumption and risk of esophageal cancer (EC) is still inconclusive. We examined the association of tea and coffee consumption with EC risk among 442,143 men and women without cancer at baseline from 9 countries of the European Prospective Investigation into Cancer and Nutrition. Tea and coffee intakes were recorded using country-specific validated dietary questionnaires. Cox regression models were used to analyze the relationships between tea and coffee intake and EC risk. During a mean follow-up of 11.1 years, 339 participants developed EC, of which 142 were esophageal adenocarcinoma (EAC) and 174 were esophageal squamous cell carcinoma (ESCC). In the multivariable models, no significant associations between tea (mostly black tea), and coffee intake and risk of EC, EAC and ESCC were observed. In stratified analyses, among men coffee consumption was inversely related to ESCC (HR for comparison of extreme tertiles 0.42, 95% CI 0.20-0.88; p-trend=0.022), but not among women. In current smokers, a significant and inverse association was observed between ESCC risk and tea (HR 0.46, 95% CI 0.23-0.93; p-trend=0.053) and coffee consumption (HR 0.37, 95% CI 0.19-0.73; p-trend=0.011). However, no statistically significant findings were observed using the continuous variable (per 100 mL/d). These data did not show a significant association between tea and coffee consumption and EC, EAC and ESCC, although a decreased risk of ESCC among men and current smokers is suggested, but need to be confirmed in further prospective studies including more cases. © 2014 UICC.

    AIM: To assess whether the molecular markers of malignant tumors could improve the understanding of tumor characteristics, and to observe the characteristics of expression of cell cycle markers Ki-67 and cydin A in esophageal carcinoma and to analyze the relationship between proliferative activity of cancer cells and clinicopathological factors.METHODS: Seventy of surgically resected esophageal squamous cell carcinoma (SCC) were examined by immunohistochemistry utilizing commercially available antibodies. Nuclear staining was regarded as a positive result. At least 50 fields in each tumor and non-tumor section were evaluated at a medium power (x200) to determine the proportion of tumor cells and the staining intensity of nuclei in the entire sections.RESULTS: Ki-67 and cyclin A were only expressed in base cells of normal esophageal mucosa. The positive immunostaining of nuclei of SCC was significantly higher than that in normal esophageal mucosa (t= 13.32 and t= 7.52,respectively, P<0.01). The distribution of positively stained was more diffuse and stronger in poorly differentiated SCC. Both Ki-67 and cyclin A expressions were related to histological grades of tumors (t = 3.5675 and t = 3.916; t= 2.13, respectively, P<0.05) but not to the sex and age of the patients, tumor size, lymphatic invasion, location, or stage grouping.CONCLUSION: The proliferative activity of cancer cells may be understood by immunohistochemistry of Ki-67 and cyclin A in Chinese patients with esophageal SCC. These cell cycle markers may serve as an indicator of cancer cell proliferation rate. The overexpression of cell cycle markers Ki-67 and cyclin A suggests the poor SCC differentiation in patients with esophageal carcinoma.

    AIM: In order to detect risk factors for esophageal cancer,a national research program was carried out during the Eighth Five-Year Plan (from 1991 to 1995). METHODS: Cixian County and Chichen County in Hebei Province were selected as the index and the control for the study fields with higher or lower incidence of esophagus cancer in China, respectively. In these areas, we investigated the pollution of three nitrogenous compounds in well water for drinking and the use of nitrogen fertilizer in farming. RESULTS: In well water, nitrate nitrogen, nitrite nitrogen and ammonia nitrogen were 8.77 mg/L, 0.014 mg/L and 0.009 mg/L in Cixian County in 1993, respectively. They were significantly higher than their levels (3.84 mg/L, 0.004 mg/L and 0.004 mg/L) in Chichen County (P<0.01, t=6.281,t=3.784,t=3.775). There was a trend that the nitrogenous compounds in well water increased from 1993 to 1996.The amount of nitrogen fertilizer used in farming was 787.6 kg per hectare land in Cixian County in 1991, significantly higher than 186 kg per hectare in Chichen County (t=9.603,P<0.001). CONCLUSION: These investigations indicate that the poilution of nitrogenous compounds in well water for drinking is closely related to the use of nitrogen fertlizer in farming, and there is a significantly positive correlation between the level of three nitrogenous compounds in well water and the mortality ofesophageal cancer (correlation coefficient =0.5992). We suggest that improvement of well system for drinking water quality should be an effective measure for esophageal cancer prevention and control in rural areas.

    Aim: To investigate the effects of insulin on enhancing 5-fluorouracil (5-FU) anti-cancer functions and its mechanisms in the human esophageal cancer cell line (Eca 109) and human colonic cancer cell line (Ls-174-t). Methods: The effect of insulin/5-FU combination treatment on the growth of Eca 109 and Ls-174-t cells was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay. After insulin treatment or insulin/5-FU treatment, cell cycle distri-bution of both cell lines was analyzed by flow cytometry. Western blot assay was used to assess the expression of caspase-3 and thymidylate synthase (TS).Apoptosis was detected by flow cytometry, DNA fragmentation assay, and termi-nal transferase dUTP nick end labeling assay (TUNEL). Moreover, the changes of 5-FU uptake after insulin pretreatment were detected by HPLC assay and Western blot analysis. Results: We found that insulin enhanced the inhibitory effect of 5-FU on cell proliferation when Eca 109 cells and Ls- 174-t cells were pretreated with insulin for the appropriate time. Insulin increased the cell number of the S phase and the uptake of 5-FU. Insulin/5-FU treatment enhanced apoptosis of tumor cells and upregulated the expression of cleaved caspase-3 compared with 5-FU treatment.Moreover, insulin/5-FU treatment induced the changes of free TS and the TS ternary complex level compared with 5-FU treatment in Eca 109 and Ls-174-t cells.Conclusion: These data suggest that insulin enhances anticancer functions of 5-FU when it is treated before 5-FU for the appropriate time in human esophageal and colonic cancer cell lines.

    Diets high in vegetables and fruits have been suggested to be inversely associated with risk of gastric cancer. However, the evidence of the effect of variety of consumption is limited. We therefore investigated whether consumption of a variety of vegetables and fruit is associated with gastric and esophageal cancer in the European Prospective Investigation into Cancer and Nutrition study. Data on food consumption and follow-up on cancer incidence were available for 452,269 participants from 10 European countries. After a mean follow-up of 8.4 years, 475 cases of gastric and esophageal adenocarcinomas (180 noncardia, 185 cardia, gastric esophageal junction and esophagus, 110 not specified) and 98 esophageal squamous cell carcinomas were observed. Diet Diversity Scores were used to quantify the variety in vegetable and fruit consumption. We used multivariable Cox proportional hazard models to calculate risk ratios. Independent from quantity of consumption, variety in the consumption of vegetables and fruit combined and of fruit consumption alone were statistically significantly inversely associated with the risk of esophageal squamous cell carcinoma (continuous hazard ratio per 2 products increment 0.88; 95% CI 0.79-0.97 and 0.76; 95% CI 0.62-0.94, respectively) with the latter particularly seen in ever smokers. Variety in vegetable and/or fruit consumption was not associated with risk of gastric and esophageal adenocarcinomas. Independent from quantity of consumption, more variety in vegetable and fruit consumption combined and in fruit consumption alone may decrease the risk of esophageal squamous cell carcinoma. However, residual confounding by lifestyle factors cannot be excluded.

    We evaluated the failure pattern of the celiac axis, gastric lymph node, and treatment outcome in the upper and mid-esophageal region of cancer patients treated by definitive radiotherapy, except when treating the celiac axis and gastric lymph node for treatment volume, retrospectively. Materials and Methods: The study constituted the evaluation 108 patients with locally advanced esophageal cancer receiving radiotherapy or a combination of radiotherapy and chemotherapy at Chonbuk National University Hospital from January 1986 to December 2006. In total, 82 patients treated by planned radiotherapy, except when treating the celiac axis and gastric lymph node for treatment volume, were analysed retrospectively. The study population consisted of 78 men and 2 women (mean age of 63.2 years). In addition, 51 patients received radiotherapy alone, whereas 31 patients received a combination of radiation therapy and chemotherapy. The primary cancer sites were located in the upper portion (17 patients), and mid portion (65 patients), respectively. Further, the patients were in various clinical stages including T1N0-1M0 (7 patients), T2N0-1M0 (18 patients), T3N0-1M0 (44 patients) and T4N0-1M0 (13 patients). The mean follow up period was 15 months. Results: The various treatment outcomes included complete response (48 patients), partial response (31 patients) and no response (3 patients). The failure patterns of the lymph node were comprised of the regional lymph node (23 patients) and the distance lymph node which included celiac axis and gastric lymph node (13 patients). However, metastasis was not observed in the regional and distant lymph node in 10 patients, whereas 36 patients were not evaluated. Furthermore, of the 13 patients who developed celiac axis and gastric lymph node metastases, 3 were in stage T1N0-1M0 and 10 were in stage T2-4N0-1M0.

    Lysosome-associated transmembrane-4 beta (LAPTM4B) is an oncogene that participates tumorgenesis in a variety of human solid tumors, and it has two alleles named as LAPTM4B*1 and *2. The present study aimed to identify the association of LAPTM4B genotype with clinicopathological features and prognosis in colorectal and esophageal cancer patients. Genotypes of LAPTM4B were determined by PCR in 167 colon cancer cases (72 patients in a discovery cohort and 95 patients in a testing cohort), 160 rectal cancer cases and 164 esophageal cancer cases. Association between the LAPTM4B gene polymorphism and clinicopathological variables was calculated by Chi-square test or Fisher's exact test. Patient survival differences were calculated by the Kaplan-Meier method. Prognostic factors were determined with Log-rank test and Cox regression model. LAPTM4B *1/1 was more frequently detected in colon cancer patients with lymph node metastasis and TNM III+IV stages in total colon cancer (discovery + testing cohorts). LAPTM4B *2/2 decreased in recurrent patients in total colon cancer patients (P = 0.045). Kaplan-Meier survival curves and Log-rank test showed that LAPTM4B*1 was correlated with shorter overall survival (OS) in discovery and testing cohorts of colon cancer (P = 0.0254 and 0.0292, respectively), but not in rectal and esophageal cancer cases (P = 0.7669 and 0.9356, respectively). Multivariate analysis showed that LAPTM4B genotype was an independent prognostic factor for OS in total colon cancer [P = 0.004, hazard ratio (HR) = 0.432; 95% confidence interval (CI) = 0.243-0.768], but not in rectal and esophageal cancers (P = 0.791, HR = 1.073, 95% CI = 0.638-1.804 and 0.998, HR = 1.000, 95% CI = 0.663-1.530, respectively). These findings suggested that LAPTM4B allele *1 was a risk factor associated with poor prognosis in patients with colon cancer, but not in patients with rectal or esophageal cancers. LAPTM4B genotype status might be a useful prognostic indicator for patients

    Rapid increases in the incidence of esophageal adenocarcinoma (EAC) in high-income countries in the past decades have raised public health concerns. This study is the first to predict the future burden of esophageal cancer by histological subtype using international incidence data. Data on esophageal cancer incidence by year of diagnosis, sex, histology, and age group were extracted from 42 registries in 12 countries included in the last three volumes (VIII-X) of Cancer Incidence in Five Continents, contributing at least 15 years of consecutive data. Numbers of new cases and incidence rates were predicted up to 2030 by fitting and extrapolating age-period-cohort models; the differential impact of demographic vs. risk changes on future cases were examined. The number of new AC cases is expected to increase rapidly 2005-2030 in all studied countries as a combined result of increasing risk and changing demographics. In contrast, the incidence of esophageal squamous cell carcinoma (ESCC) is predicted to continue decreasing in most countries. By 2030, 1 in 100 men in the Netherlands and the United Kingdom are predicted to be diagnosed with EAC during their lifetime. The burden from EAC is expected to rise dramatically across high-income countries and has already or will surpass ESCC incidence in the coming years, especially among men. Notwithstanding the inherent uncertainties in trend-based predictions and in subtype misclassification, these findings highlight an ongoing transition in the epidemiology of esophageal cancer that is highly relevant to future cancer control planning and clinical practice.

    Full Text Available The high morbidity and mortality of patients with esophageal (E and gastro-esophageal junction (GEJ cancers, warrants new pre-clinical models for drug testing. The utility of primary tumor xenografts (PTXGs as pre-clinical models was assessed. Clinicopathological, immunohistochemical markers (p53, p16, Ki-67, Her-2/neu and EGFR, and global mRNA abundance profiles were evaluated to determine selection biases of samples implanted or engrafted, compared with the underlying population. Nine primary E/GEJ adenocarcinoma xenograft lines were further characterized for the spectrum and stability of gene/protein expression over passages. Seven primary esophageal adenocarcinoma xenograft lines were treated with individual or combination chemotherapy. Tumors that were implanted (n=55 in NOD/SCID mice had features suggestive of more aggressive biology than tumors that were never implanted (n=32. Of those implanted, 21/55 engrafted; engraftment was associated with poorly differentiated tumors (p=0.04 and older patients (p=0.01. Expression of immunohistochemical markers were similar between patient sample and corresponding xenograft. mRNA differences observed between patient tumors and first passage xenografts were largely due to loss of human stroma in xenografts. mRNA patterns of early vs late passage xenografts and of small vs large tumors of the same passage were similar. Complete resistance was present in 2/7 xenografts while the remaining tumors showed varying degrees of sensitivity, that remained constant across passages. Because of their ability to recapitulate primary tumor characteristics during engraftment and across serial passaging, PTXGs can be useful clinical systems for assessment of drug sensitivity of human E/GEJ cancers.

    Esophageal cancer is common worldwide, with poor prognosis. Smoking, including exposure to polyaromatic hydrocarbons like benzo[a]pyrene (BaP), is a major risk factor. In human esophageal HET-1A cells, we found that time-dependent BaP-DNA binding was associated with upregulation of CYP1B1, but not CYP1A1, mRNA and protein. The dietary flavonoid 5,7-dimethoxyflavone significantly inhibited BaP-DNA binding and down-regulated BaP-induced CYP1B1 mRNA and protein. 3',4'-Dimethoxyflavone was an even more potent inhibitor of CYP1B1 expression, while resveratrol had no effect. Thus, dietary methoxylated flavones inhibited BaP-induced CYP1B1 transcription in a cell-specific manner and hold promise as chemopreventive agents in esophageal carcinogenesis.

    Several studies have evaluated associations between the characteristics of patients with esophageal and gastric cancer and survival, but these associations remain unclear. We described the distribution of demographic and lifestyle factors among patients with esophageal and gastric cancer in Japan, and investigated their potential effects on survival. Between 2003 and 2007, 24- to 95-year-old Japanese patients with esophageal and gastric cancer were enrolled in the BioBank Japan Project. The analysis included 365 patients with esophageal squamous cell carcinoma (ESCC) and 1574 patients with gastric cancer. Hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality were estimated using medical institution-stratified Cox proportional hazards models. During follow-up, 213 patients with ESCC (median follow-up, 4.4 years) and 603 patients with gastric cancer (median follow-up, 6.1 years) died. Among patients with ESCC, the mortality risk was higher in ever drinkers versus never drinkers (multivariable HR = 2.37, 95% CI: 1.24, 4.53). Among patients with gastric cancer, the mortality risk was higher in underweight patients versus patients of normal weight (multivariable HR = 1.66, 95% CI: 1.34, 2.05). Compared to patients with gastric cancer with no physical exercise habit, those who exercised ≥3 times/week had a lower mortality risk (multivariate HR = 0.75, 95% CI = 0.61, 0.93). However, lack of stage in many cases was a limitation. Among patients with ESCC, alcohol drinkers have a poor prognosis. Patients with gastric cancer who are underweight also have a poor prognosis, whereas patients with physical exercise habits have a good prognosis. Copyright © 2017 The Authors.

    The evidence for an association between occupational asbestos exposure and esophageal, gastric and colorectal cancer is limited. We studied this association specifically addressing risk differences between relatively low and high exposure, risk associated with cancer subtypes, the influence of potential confounders and the interaction between asbestos and smoking in relation to cancer risk. Using the Netherlands Cohort Study (n = 58,279 men, aged 55-69 years at baseline), asbestos exposure was estimated by linkage to a job-exposure matrix. After 17.3 years of follow-up, 187 esophageal, 486 gastric and 1,724 colorectal cancer cases were available for analysis. The models adjusted for age and family history of cancer showed that mainly (prolonged) exposure to high levels of asbestos was statistically significantly associated with risk of esophageal adenocarcinoma (EAC), total and distal colon cancer and rectal cancer. For overall gastric cancer and gastric non-cardia adenocarcinoma (GNCA), also exposure to lower levels of asbestos was associated. Additional adjustment for lifestyle confounders, especially smoking status, yielded non-significant associations with overall gastric cancer and GNCA in the multivariable-adjusted model, except for the prolonged highly exposed subjects (tertile 3 vs. never: HR 2.67, 95% CI: 1.11-6.44 and HR 3.35, 95% CI: 1.33-8.44, respectively). No statistically significant additive or multiplicative interaction between asbestos and smoking was observed for any of the studied cancers. This prospective population-based study showed that (prolonged) high asbestos exposure was associated with overall gastric cancer, EAC, GNCA, total and distal colon cancer and rectal cancer.

    Full Text Available Abstract Background The purpose of this study was to evaluate the association of multi-genotype polymorphisms with the stepwise progression of esophageal squamous cell cancer (ESCC and the possibility of predicting those at higher risk. Methods A total of 1,004 subjects were recruited from Feicheng County, China, between Jan. 2004 and Dec. 2007 and examined by endoscopy for esophageal lesions. These subjects included 270 patients with basal cell hyperplasia (BCH, 262 patients with esophageal squamous cell dysplasia (ESCD, 226 patients with ESCC, and 246 controls with Lugol-voiding area but diagnosed as having normal esophageal squamous epithelial cells by histopathology. The genotypes for CYP2E1 G1259C, hOGG1 C326G, MTHFR C677T, MPO G463A, and ALDH2 allele genes were identified in blood samples collected from all participants. Results The alleles ALDH2 and MTHFR C677T were critical for determining individual susceptibility to esophageal cancer. Compared to the ALDH 1*1 genotype, the ALDH 2*2 genotype was significantly associated with increased risks of BCH, ESCD, and ESCC. However, the TT genotype of MTHFR C677T only increased the risk of ESCC. Further analysis revealed that the combination of the high-risk genotypes 2*2/1*2 of ALDH 2 and TT/TC of MTHFR C677T increased the risk of BCH by 4.0 fold, of ESCD by 3.7 fold, and ESSC by 8.72 fold. The generalized odds ratio (ORG of the two combined genotypes was 1.83 (95%CI: 1.55-2.16, indicating a strong genetic association with the risk of carcinogenic progression in the esophagus. Conclusions The study demonstrated that the genotypes ALDH2*2 and MTHFR 677TT conferred elevated risk for developing esophageal carcinoma and that the two susceptibility genotypes combined to synergistically increase the risk.

    Full Text Available BACKGROUND: Cancer-associated fibroblasts (CAF are activated fibroblasts in the cancer stroma and play an important role in cancer progression. Some reports have indicated the correlation between the expression of CAF markers and adverse prognosis in several cancers. However, no reports have studied CAF phenotype and its clinical relevance in esophageal squamous cell carcinoma (ESCC. METHODS: We investigated CAF phenotype of ESCC based on histology and immunohistochemical expressions of five CAF markers such as fibroblast activation protein (FAP, smooth muscle actin (SMA, fibroblast-specific protein-1 (FSP1, platelet-derived growth factor receptor (PDGFRα, and PDGFRβ in 116 ESCC tissue samples. Besides, we also examined the correlation of the CAF phenotype with clinical relevance as well as other cancer-microenvironment related factors. RESULTS: Histologically immature CAF phenotype was correlated with poor prognosis (p<0.001 and associated with increased microvessel density, increased tumor associated macrophages, and epithelial to mesenchymal transition. CAF markers were characteristically expressed in stromal fibroblast close to tumor cells and the expression pattern of 5 CAF markers was highly heterogeneous in every individual cases. Of five CAF markers, SMA, FSP1, and PDGFRα were unfavorable prognostic indicators of ESCC. The number of positive CAF markers was greater in ESCC with immature CAFs than in those with mature ones. CONCLUSIONS: Our results demonstrate that histologic classification of CAF phenotype is a reliable and significant prognostic predictor in ESCC. CAF markers have the potential to be diagnostic and therapeutic targets in ESCC.

    Esophageal cancer (EC) is commonly diagnosed in South Africa (SA), with high incidences occurring in SA's black population. Moringa oleifera (MO), a multipurpose tree, is used traditionally for its nutritional and medicinal properties. It has been used for the treatment of a variety of ailments, including cancer. We investigated the antiproliferative effect of MO crude aqueous leaf extract (MOE) on a cancerous esophageal cell line (SNO). SNO cells were exposed to a range of MOE dilutions to evaluate cytotoxicity (MTT assay). Oxidative stress was determined using the TBARS assay. The comet assay was used to assess DNA damage. We then determined cell death mechanisms by measuring phosphatidylserine (PS) externalization (flow cytometry), caspase-3/7 and caspase-9 activities, and adenosine triphosphate (ATP) levels (luminometry). Protein expression of Smac/DIABLO and PARP-1 was determined by western blotting. SNO cells were treated with a range of MOE dilutions to obtain an IC50 value of 389.2 μg/mL MOE (24 h), which was used in all subsequent assays. MOE significantly increased lipid peroxidation (P < .05) and DNA fragmentation (P < .0001) in SNO cells. The induction of apoptosis was confirmed by the increase in PS externalization (P < .0001), caspase-9 (P < .05) and caspase-3/7 (P = .22) activities, and decreased ATP levels (P < .0001). MOE significantly increased both the expression of Smac/DIABLO protein and cleavage of PARP-1, resulting in an increase in the 24-kDa fragment (P < .001). MOE possesses antiproliferative effects on SNO EC cells by increasing lipid peroxidation, DNA fragmentation, and induction of apoptosis.

    Full Text Available Esophageal cancer was the fifth most commonly diagnosed cancer and the fourth leading cause of cancer-related death in China in 2009. Genetic factors might play an important role in the carcinogenesis of esophageal squamous cell carcinoma (ESCC. We conducted a hospital-based case-control study to evaluate ten NAT2 tagging single nucleotide polymorphisms (SNPs on the risk of ESCC. Six hundred and twenty-nine ESCC cases and 686 controls were recruited. Their genotypes were determined using the ligation detection reaction method. In the single locus analyses, there was a borderline statistically significant difference in genotype frequencies of NAT2 rs1565684 T>C SNP between the cases and the controls (p = 0.057. The NAT2 rs1565684 CC genotype was associated with a borderline significantly increased risk for ESCC (CC vs. TT: adjusted OR = 1.77, 95% CI = 0.97-3.21, p = 0.063 and CC vs. TT/TC: adjusted OR = 1.68, 95% CI = 0.93-3.04, p = 0.085. The association was evident among older patients and patients who never drunk. After the Bonferroni correction, in all comparison models, NAT2 rs1565684 T>C SNP was not associated with ESCC risk (p>0.05. For the other nine NAT2 SNPs, after Bonferroni correction, in all comparison models, the nine SNPs were also not associated with ESCC risk (p>0.05. Thus, nine NAT2 tagging SNPs were not associated with risk of ESCC. NAT2 rs1565684 T>C SNP might play a slight role in ESCC etiology. Additional, larger studies and tissue-specific biological characterization are required to confirm the current findings.

    Endoscopic evaluation after chemoradiotherapy (CR) is impossible with an esophageal stent in place. The main study objective was to evaluate self-expanding plastic stent (SEPS) removal post-CR. Secondary end-points were the improvement of dysphagia and patients' quality of life. From October 2008 to March 2011, 20 dysphagic patients who suffered from advanced esophageal cancer were enrolled in a multicenter, prospective study. SEPS was inserted prior to CR and then removed endoscopically. SEPS efficiency (dysphagia score) and tolerance, as well as the patients' quality of life (European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire validated for the esophagus), were monitored. Continuous variables were compared using a paired t-test analysis for matched data. A P-value of less than 0.05 was considered statistically significant. Twenty patients (15 men and 5 women), aged 61.5 years (±9.88) (range 43-82 years), with adenocarcinoma (n = 12) and squamous cell carcinoma (n = 8), were enrolled. SEPS were successfully inserted in all patients (100%). There was one perforation and three episodes of migration. All of these complications were medically treated. The mean dysphagia score at the time of stent placement was 2.79 (0.6). Mean dysphagia scores obtained on day 1 and day 30 post-SEPS placement were 0.7 (0.9) (P cancer. Early stenting by SEPS prior to and during CR may reduce dysphagia and improve quality of oral alimentation. © 2013 Wiley Periodicals, Inc. and the International Society for Diseases of the Esophagus.

    Background: Paclitaxel poliglumex (PPX) is a drug conjugate that links paclitaxel to poly-L-glutamic acid thereby increasing its radiation enhancement factor to 4.0–8.0 compared to 1.5–2.0 for paclitaxel. In previous phase I studies, The Brown University Oncology Group evaluated PPX with concurrent radiation and PPX/cisplatin/RT. A phase II study was subsequently performed to evaluate the pathologic response rate of neoadjuvant PPX, cisplatin, and radiation for patients with esophageal cancer. Methods: Eligible patients had pathologically confirmed adenocarcinoma or squamous cell carcinoma of the esophagus or GE junction with no evidence of distant metastasis. Patients received weekly PPX 50 mg/m2 and cisplatin 25 mg/m2 for 6 weeks with concurrent 50.4 Gy of radiation. Six to eight weeks after completion of chemoradiotherapy, patients underwent surgical resection. Results: The study has completed accrual of 40 patients, 37 with adenocarcinoma and 3 with squamous cell cancer. The median age is 62 years. Toxicity data are available for the first 35 patients. Four of 35 patients experienced grade 4 non-hematologic toxicities, which included electrolyte abnormalities, glucose intolerance, hypersensitivity reaction, and thromboembolus. Eleven of 35 patients had grade 3 non-hematologic toxicities including electrolyte abnormalities (n=5), nausea (n=3), dysphagia (n=2), fatigue (n=2), glucose intolerance (n=2), and hypersensitivity reaction (n=1). Grade 3 anorexia was reported in only 1 patient who subsequently was given TPN. No patients required a feeding tube. There were no grade 4 hematologic toxicities; grade 3 hematologic toxicities included neutropenia (n=2) and anemia (n=1). Of the first 28 patients undergoing surgery, all with adenocarcinoma, 7 of 28 (25%) have had a pathologic complete response. Conclusion: PPX, cisplatin and concurrent radiation is a well tolerated, easily administered regimen for esophageal cancer with a very low incidence of significant

    AIM: Phase Ⅰ/Ⅱ enzymes metabolize environmental carcinogens and several functional polymorphisms have been reported in their encoding genes. Although their significance with regard to esophageal carcinogenicity has been examined epidemiologically, it remains controversial. The present systematic review of the literature was performed to clarify associations.METHODS: Eligible studies were case-control or cohort studies published until September 2004 that were written in any language. From PubMed and a manual review of reference lists in relevant review articles, we obtained 16 studies related to the CYP1A1 Ile-Val substitution in exon 7, CYP1A1MspI polymorphisms, CYP2E1 RsaI polymorphisms,GSTM1 null type, GSTT1 null type and GSTP1 Ile104Val.All were of case-control design. Summary statistics were odds ratios (ORs) comparing heterozygous-, homozygousnon-wild type or these two in combination with the homozygous wild type, or the null type with the non-null type for GSTM1 and GSTT1. A random effect model was used to estimate the summary ORs. A meta-regression analysis was applied to explore sources of heterogeneity. RESULTS: Individuals with the Ile-Val substitution in CYP1A1 exon 7 had increased esophageal cancer risk,with ORs (95%CI) compared with Ile/Ile of 1.37 (1.09-1.71),2.52 (1.62-3.91) and 1.44 (1.17-1.78) for Ile-Val, Val/Val genotype and the combined group. No significant association was found between esophageal cancer risk and the other genetic parameters.CONCLUSION: A significant association exists between the CYP1A1 Ile-Val polymorphism and risk of esophageal cancer. Polymorphisms that increase the internal exposure to activated carcinogens may increase the risk of esophageal cancer.

    Patient 1 was a 63-year-old woman whose chief complaint was a mass in the left breast. Physical examination revealed an inverted left nipple, a very large mass on the anterior aspect of the sternum, and erythema. Because the tumor had directly invaded the sternum, T4cN3M0, stage IIIC breast cancer was diagnosed. The patient preoperatively received chemotherapy with 6 courses of FEC100 (5-fluorouracil, epirubicin, and cyclophosphamide) and 5 courses of nanoparticle albumin -bound paclitaxel (260 mg/m2), which enabled a partial response. Patient 2 was an 83-year-old woman whose chief complaint was a mass in the upper internal and external quadrants of the right breast measuring 20×15 cm and erythema. The mass was accompanied by enlarged right axillary lymph nodes(T4bN1M0, stage IIIB breast cancer). Both patients underwent core needle biopsy of the skin and breast masses. They were both diagnosed with invasive, lobular, triple-negative breast cancer (estrogen receptor negative, progesterone receptor negative, human epidermal growth factor receptor 2 negative). The surgical resection line was drawn to include the extensive skin invasion, and mastectomy and axillary dissection were performed. Skin grafting was scheduled but the retromammary space on the healthy side was dissected to the anterior border of the latissimus dorsi muscle, and the skin of the healthy side was used to cover the defect on the affected side. Consequently, the pendulous breast on the healthy side was elevated. This surgical technique provided an excellent aesthetic outcome without any skin problems, because autologous skin was used to fill the defect. Radiotherapy could subsequently be administered as scheduled. This procedure may be useful for elderly patients.

    The 5-year survival of patients with low socioeconomic status (SES) and esophageal cancer is significantly lower than that in patients with high SES. It is poorly understood what causes these worse outcomes. We hypothesized that a qualitative approach could elucidate the underlying causes of these differences. Patients with a diagnosis of esophageal cancer were recruited through flyers in regional cancer centers as well as through Facebook advertisements in cancer support groups and newspapers; they participated in a 1-hour semistructured interview or completed an online survey. Patients were stratified into low- and high-SES groups and were surveyed about their health history and access to cancer care. Data were coded into common themes based on participant responses. Eighty patients completed the interviews or surveys, with 38 in the high-SES group and 42 in the low-SES group. There were no clinically significant differences between the groups in comorbidities and cancer staging. Patients with low SES were offered operative treatment at significantly lower rates (19 of 42 [44.7%] versus 29 of 38 [76.3%]; p = 0.0048), had a decreased rate of second opinions (10 of 42 [23.8%] versus 25 of 38 [65.8%]; p = 0.00016), and were more likely to lose their jobs (14 of 42 [33.3%] versus 1 of 38 [2.6%]; p = 0.00044) than their high-SES counterparts. Thematic analysis found that communication difficulties, lack of understanding of treatment, and financial troubles were consistently reported more prominently in the lower-SES groups. Having a facilitator (eg, social worker) improved care by helping patients navigate complex treatments and financial concerns. Financial and communication barriers exist, which may lead to disparities in cancer outcomes for patients with low SES. There is a critical need for medical advocates to assist patients with limited resources. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

    We evaluated the LFP combined with radiation therapy for the treatment of advanced or recurrent esophageal cancer. The patients consisted of 4 inoperable cases, 4 cases in combination with operation, and 5 cases with recurrent tumor. The response rate was 80% (CR2, PR6, NC1 and PD1). We conclude that the LFP combined with radiation therapy was effective and useful for the treatment of advanced or recurrent esophageal cancer. (author)

    Full Text Available A 72-year-old woman was admitted to our hospital for esophagectomy for esophageal cancer. On the third postoperative day, she developed polyuria (3.8 L/day, massive natriuresis, hyponatremia (112 mEq/L, hyperkalemia (5.6 mEq/L, and decreased central venous pressure, which was refractory to isotonic saline infusion. Laboratory findings indicated proximal tubular injury (high urinary β2-microglobulin, coexistence of hypouricemia together with reduced aldosterone action at the cortical collecting duct. A diagnosis of salt-losing nephropathy was made and sodium correction was done with 3% saline and fludrocortisone. She responded well to therapy. The cause of hyponatremia was considered renal tubular dysfunction together with elevated antidiuretic hormone level. Postoperatively, it is important to look for the development of salt-losing nephropathy.

    Esophageal squamous cell neoplasia (ESCN) is the sixth leading cause of cancer death worldwide. Most deaths due to ESCN occur in developing countries, with highest risk areas in northern China. Lugol's chromoendoscopy (LCE) is the gold-standard for ESCN screening; while the sensitivity of LCE for ESCN is >95%, LCE suffers poor specificity (< 65%) due to false positive findings from inflammatory lesions. High resolution microendoscopy (HRME) uses a low-cost, fiber-optic fluorescence microscope to image morphology of the surface epithelium without need for biopsy. We developed a tablet-interfaced HRME with automated, real-time image analysis. In an in vivo study of 177 patients referred for endoscopy in China, use of the algorithm identified neoplasia with a sensitivity and specificity of 95% and 91% compared to the gold standard of histology.

    Full Text Available Abstract Introduction Takotsubo cardiomyopathy has increasingly been reported in the medical literature in recent years. Much is still unknown regarding risk factors and clinical relationships. We contribute this case report to the growing set of literature on the topic. Case presentation We report the case of a 64-year-old woman with esophageal cancer who developed takotsubo cardiomyopathy, a form of reversible heart failure, and we present a review of the literature. Patients present with symptoms similar to an acute coronary syndrome; however, cardiac catheterization reveals patent coronary arteries, and symptoms of heart failure resolve completely within weeks. Conclusion It is important that clinicians consider takotsubo cardiomyopathy in the differential diagnosis of heart failure and gain a basic understanding of the clinical presentation and diagnosis.

    Herein, we report the treatment outcomes of patients with limited cervical lymph node recurrence after esophagectomy for esophageal cancer. Between April 2010 and December 2013, 8 patients with cervical lymph nodes recurrence were diagnosed and treated in our department. All patients were detected with recurrent disease by using positron emission tomography computed tomography(PET-CT), and among these, 5 patients had solitary node recurrence. Initial treatments were irradiation therapy in 5 patients and lymphadenectomy in 3 patients. Four of 5 patients underwent irradiation therapy and lymphadenectomy. Four of 5 patients with solitary node recurrence are still alive without relapse of disease. In conclusion, PET-CT can be useful for early detection of recurrent disease after esophagectomy. Appropriate therapy for patients with solitary cervical lymph node recurrence is associated with long-term survival after recurrence.

    We investigated the anti-tumor effects of dual cancer specific-oncolytic adenovirus Ad-VP on esophageal cancer(EC).The anti-tumor activity of Ad-VP was compared with that of the control recombinant adenoviruses (Ad-GP,Ad-Apoptin,Ad-EGFP) in human esophageal cancer cell EC-109 and human normal liver cell L02 in vitro.In 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assays,the growth of EC-109 cells was slightly inhibited by Ad-GP.Ad-Apoptin and Ad-EGFP.However,Ad-VP induced a significant cytotoxic effect.Infection of EC-109 cells with Ad-VP resulted in a significant induction of apoptosis of them in vitro,detected by 4′,6-diamidino-2-phenylindole(DAPI) or acridine orange and ethidium bromide staining.The results of Western blot and flow cytometric assay indicate the loss of mitochondrial membrane potential(△ψm),the release of cytochrome c and the activation of caspase-3,6 and 7 in Ad-VP infiected EC-109 cells.In contrast,all these assays show almost no effects of the recombinant adenoviruses on L02 cells.These results demonstrate that the treatment of tumors with Ad-VP selectively inhibits tumor growth and induces apoptosis of esophageal cancer cells.Ad-VP may provide a novel and powerful strategy for cancer gene therapy.

    Full Text Available Oral glutamine supplementation is highly effective in preventing and delaying radiation-induced esophagitis, one of the most common discomforting side effects of radiation to the thoracic area among lung cancer patients. According to the literature, lung cancer is the leading cause of death among all cancers with the highest incidence worldwide. This paper aims to emphasize the importance of oral glutamine supplementation in preventing radiation-induced esophagitis among lung cancer patients. Several databases have been searched and seven studies included in this review (five randomized control studies, one quasi-experimental study and one systematic review with a total of 453 patients. The patients in these studies were diagnosed with lung cancer regardless of type or stage. The patients were either assigned to an intervention group (glutamine supplementation or a control group. These studies were conducted in the US, Turkey, Spain, and Greece from 2003 until 2012. The results showed that 10 mg of oral glutamine three times per day on a daily basis (from one month before starting radiation until one month after completion of radiationwas effective in preventing and delaying radiation-induced esophagitis.

    Background Esophageal cancer has traditionally been associated with very poor outcomes. A number of therapies are available for the treatment and palliation of esophageal cancer, but little systematic evidence compares the efficacy of different treatment strategies. This meta-analysis aimed to investigate whether treatments in addition to radiotherapy could provide better efficacy and safety. Material/Methods We identified a total of 12 eligible studies with 18 study arms by searching PubMed, the Cochrane Library, EMBASE, and Clinical Trials.gov without time or language restrictions. The final search was conducted on 17 August 2016. We calculated mean differences (MD) and risk ratios (RR) with 95% confidence intervals (CI) for continuous and dichotomous data, respectively. Heterogeneity was calculated and reported using Tau2, Chi2, and I2 analyses. Results Twelve studies with 18 study arms were included in the analysis. Addition of surgery to chemo-radiotherapy resulted in improved median survival time (p=0.009) compared with chemo-radiotherapy alone, but all other outcomes were unaffected. Strikingly, and in contrast with patients with squamous cell carcinomas, the subset of patients with adenocarcinoma who received therapies in addition to radiotherapy showed a significant improvement in median survival time (p<0.0001), disease-free survival (p=0.007), 2-year survival rates (p=0.002), and 3-year survival rates (p=0.01). The incidence of adverse effects increased substantially with additional therapies. Conclusions This meta-analysis reveals stark differences in outcomes in patients depending on the type of carcinoma. Patients with squamous cell carcinoma should be educated about the risks and benefits of undergoing multiple therapies. PMID:28214903

    Full Text Available Purpose : In this study, we present the clinical implementation of a novel transoral balloon centering esophageal applicator (BCEA and the initial clinical experience in high-dose-rate (HDR brachytherapy treatment of esophageal cancer, using this applicator. Material and methods: Acceptance testing and commissioning of the BCEA were performed prior to clinical use. Full performance testing was conducted including measurements of the dimensions and the catheter diameter, evaluation of the inflatable balloon consistency, visibility of the radio-opaque markers, congruence of the markers, absolute and relative accuracy of the HDR source in the applicator using the radiochromic film and source position simulator, visibility and digitization of the applicator on the computed tomography (CT images under the clinical conditions, and reproducibility of the offset. Clinical placement of the applicator, treatment planning, treatment delivery, and patient’s response to the treatment were elaborated as well. Results : The experiments showed sub-millimeter accuracy in the source positioning with distal position at 1270 mm. The digitization (catheter reconstruction was uncomplicated due to the good visibility of markers. The treatment planning resulted in a favorable dose distribution. This finding was pronounced for the treatment of the curvy anatomy of the lesion due to the improved repeatability and consistency of the delivered fractional dose to the patient, since the radioactive source was placed centrally within the lumen with respect to the clinical target due to the five inflatable balloons. Conclusions : The consistency of the BCEA positioning resulted in the possibility to deliver optimized non-uniform dose along the catheter, which resulted in an increase of the dose to the cancerous tissue and lower doses to healthy tissue. A larger number of patients and long-term follow-up will be required to investigate if the delivered optimized treatment can

    Full Text Available Objectives. We performed this meta-analysis to summarize all the results from available studies, aiming delineating the prognostic role of miRNA in esophageal cancer. Design and Methods. We searched the electronic databases PubMed, EMBASE, and ISI Web of Science without time restrictions for the correlative literature to aggregate the survival results. Relevant data were extracted from studies investigating the relationship between miRNAs expression and survival in esophageal cancer patients. Pooled hazard ratios of miR-21and miR-375 for OS in ESCC were calculated. Results. A total of 25 studies involving 2,258 subjects analyzed the relationship between miRNA and prognosis of EC. In all, thirty-nine miRNAs associated with prognosis were reported in these studies. The pooled HR of higher miR-21 expression compared with lower miR-21 expression in ESCC was 1.84 (95% CI: 1.41–2.40, P<0.001, which could significantly predict poorer OS in ESCC. Besides, higher miR-375 was also a significant predictor for OS in ESCC, with a pooled HR of 0.55 (95% CI: 0.42–0.72, P<0.001. Conclusions. Our results support that miR-21 and miR-375 have a prognostic role in ESCC and may be useful therapeutic targets for the treatment of ESCC and meticulous follow-up for early detection of recurrence.

    Purpose: This study reports the results of the use of preoperative concurrent radiochemotherapy (CRCT) for the treatment of locoregionally advanced esophageal cancer. Materials and Methods: From 1998 through 2005, 61 patients with intrathoracic esophageal cancer at stages II-IVB (without distant organ metastasis and presumed to be respectable) received preoperative CRCT. CRCT consisted of radiotherapy (45 Gy /25 fractions /5 weeks) and FP chemotherapy (5-FU 1 g/m2/day, days 1-4 and 29-32, Cisplatin 60 mg/m2/day, days 1 and 29). An esophagectomy was planned in 4 {approx} 6 weeks after the completion of CRCT. Results: There were two treatment-related deaths. Among the 61 patients, 53 patients underwent surgery and 17 patients achieved a pathological complete response (pCR). The overall survival (OS) rates of all 61 patients at 2 and 5 years were 59.0% and 38.0%, respectively. The rates of OS and disease-free survival (DFS) of the surgically resected patients at 2 and 5 years were 61.6%, 40.1% and 53.3%, 41.8%, respectively. By univariate analysis, achievement of pCR and a clinically uninvolved distant lymph node (cM0) were favorable prognostic factors for OS and DFS. There were 27 patients that experienced a relapse-a locoregional relapse occurred in 5 patients, a distant metastasis occurred in 12 patients and combined failure occurred in 10 patients. Conclusion: The results of the current study are favorable. pCR and an uninvolved distant lymph node were found to be favorable prognostic factors.

    Full Text Available Introduction: The incidence of malnutrition in hospitalized patients is reported to be high. In particular, patients with esophageal cancer are prone to malnutrition, due to preoperative digestive system dysfunctions and short-term non-oral feeding postoperatively. Selection of an appropriate method for feeding in the postoperative period is important in these patients.   Materials and Methods: In this randomized clinical trial, 40 patients with esophageal cancer who had undergone esophagectomy between September 2008 and October 2009 were randomly assigned into either enteral feeding or parenteral feeding groups, with the same calorie intake in each group. The level of serum total protein, albumin, prealbumin, transferrin, C3, C4 and hs-C-reactive protein          (hs-CRP, as well as the rate of surgical complications, restoration of bowel movements and cost was assessed in each group.   Results: Our results showed that there was no significant difference between the groups in terms of serum albumin, prealbumin or transferrin. However, C3 and C4 levels were significantly higher in the enteral feeding group compared with the parenteral group, while hs-CRP level was significantly lower in the enteral feeding group. Bowel movements were restored sooner and costs of treatment were lower in the enteral group. Postoperative complications did not differ significantly between the groups. There was one death in the parenteral group 10 days after surgery due to myocardial infarction.   Conclusion:  The results of our study showed that enteral feeding can be used effectively in the first days after surgery, with few early complications and similar nutritional outcomes compared with the parenteral method. Enteral feeding was associated with reduced inflammation and was associated with an improvement in immunological responses, quicker return of bowel movements, and reduced costs in comparison with parenteral feeding.

    Purpose: Preoperative chemoradiation therapy (CRT) has become the standard treatment strategy for patients with resectable esophageal cancer. This multicenter phase 2 study investigated the efficacy of the addition of the epidermal growth factor receptor (EGFR) inhibitor panitumumab to a preoperative CRT regimen with carboplatin, paclitaxel, and radiation therapy in patients with resectable esophageal cancer. Methods and Materials: Patients with resectable cT1N1M0 or cT2-3N0 to -2M0 tumors received preoperative CRT consisting of panitumumab (6 mg/kg) on days 1, 15, and 29, weekly administrations of carboplatin (area under the curve [AUC] = 2), and paclitaxel (50 mg/m{sup 2}) for 5 weeks and concurrent radiation therapy (41.4 Gy in 23 fractions, 5 days per week), followed by surgery. Primary endpoint was pathologic complete response (pCR) rate. We aimed at a pCR rate of more than 40%. Furthermore, we explored the predictive value of biomarkers (EGFR, HER 2, and P53) for pCR. Results: From January 2010 until December 2011, 90 patients were enrolled. Patients were diagnosed predominantly with adenocarcinoma (AC) (80%), T3 disease (89%), and were node positive (81%). Three patients were not resected due to progressive disease. The primary aim was unmet, with a pCR rate of 22%. Patients with AC and squamous cell carcinoma reached a pCR of 14% and 47%, respectively. R0 resection was achieved in 95% of the patients. Main grade 3 toxicities were rash (12%), fatigue (11%), and nonfebrile neutropenia (11%). None of the biomarkers was predictive for response. Conclusions: The addition of panitumumab to CRT with carboplatin and paclitaxel was safe and well tolerated but could not improve pCR rate to the preset criterion of 40%.

    Purpose: We investigated whether quantitative diffusion imaging can be used as an imaging biomarker for early prediction of treatment response of esophageal cancer. Methods: Eight patients with esophageal cancer underwent a baseline and an interim MRI studies during chemoradiation on a 3T whole body MRI scanner with an 8-channel torso phased array coil. Each MRI study contained two axial diffusion-weighted imaging (DWI) series with a conventional DWI sequence and a reduced field-of-view DWI sequence (FOCUS) of varying b-values. ADC maps with two b-values were computed from conventional DWI images using a mono-exponential model. For each of DWI sequences, separate ADCall was computed by fitting the signal intensity of images with all the b-values to a single exponential model. For the FOCUS sequence, a bi-exponential model was used to extract perfusion and diffusion coefficients (ADCperf and ADCdiff) and their contributions to the signal decay. A board-certified radiologist contoured the tumor region and mean ADC values and standard deviations of tumor and muscle ROIs were recorded from different ADC maps. Results: Our results showed that (1) the magnitude of ADCs from the same ROIs by the different analysis methods can be substantially different. (2) For a given method, the change between the baseline and interim muscle ADCs was relatively small (≤10%). In contrast, the change between the baseline and interim tumor ADCs was substantially larger, with the change in ADCdiff by FOCUS DWI showing the largest percentage change of 73.2%. (3) The range of the relative change of a specific parameter for different patients was also different. Conclusion: Presently, we do not have the final pathological confirmation of the treatment response for all the patients. However, for a few patients whose surgical specimen is available, the quantitative ADC changes have been found to be useful as a potential predictor for treatment response.

    Purpose: This study investigated the trade-off in tumor coverage and organ-at-risk sparing when applying dose escalation for concurrent chemoradiation therapy (CRT) of mid-esophageal cancer, using radiobiological modeling to estimate local control and normal tissue toxicity. Methods and Materials: Twenty-one patients with mid-esophageal cancer were selected from the SCOPE1 database (International Standard Randomised Controlled Trials number 47718479), with a mean planning target volume (PTV) of 327 cm{sup 3}. A boost volume, PTV2 (GTV + 0.5 cm margin), was created. Radiobiological modeling of tumor control probability (TCP) estimated the dose required for a clinically significant (+20%) increase in local control as 62.5 Gy/25 fractions. A RapidArc (RA) plan with a simultaneously integrated boost (SIB) to PTV2 (RA{sub 62.5}) was compared to a standard dose plan of 50 Gy/25 fractions (RA{sub 50}). Dose-volume metrics and estimates of normal tissue complication probability (NTCP) for heart and lungs were compared. Results: Clinically acceptable dose escalation was feasible for 16 of 21 patients, with significant gains (>18%) in tumor control from 38.2% (RA{sub 50}) to 56.3% (RA{sub 62.5}), and only a small increase in predicted toxicity: median heart NTCP 4.4% (RA{sub 50}) versus 5.6% (RA{sub 62.5}) P<.001 and median lung NTCP 6.5% (RA{sub 50}) versus 7.5% (RA{sub 62.5}) P<.001. Conclusions: Dose escalation to the GTV to improve local control is possible when overlap between PTV and organ-at-risk (<8% heart volume and <2.5% lung volume overlap for this study) generates only negligible increase in lung or heart toxicity. These predictions from radiobiological modeling should be tested in future clinical trials.

    Less invasive operations such as laparoscopic surgery have been developed for treating gastrointestinal malignancies. However, the advantages of video-assisted thoracoscopic surgery for esophageal cancer (VATS-e) with regard to postoperative morbidity and mortality remains controversial. We investigated the postoperative clinical course of patients who underwent esophagectomy for esophageal cancer in terms of systemic inflammatory response syndrome (SIRS) induced by VATS-e (VATS-e group) or conventional open surgery (OS group) combined with laparoscopic gastric tube reconstruction. Compared with the OS group (n = 27), the VATS-e group (n = 22) had a greater thoracic operation time (VATS-e versus OS, 181 ± 56 vs 143 ± 45 minutes, respectively), and lesser duration of stay in the intensive care unit (17 ± 2 vs 32 ± 21 hours, respectively). The VATS-e group also had a lesser SIRS duration (1.5 vs 4.3 days), a lesser incidence of SIRS, a lesser number of positive SIRS criteria, and lesser serum interleukin-6 levels immediately after operation and on postoperative day (POD) 1. The heart rate in the VATS-e group was less than that in the OS group on POD 3. The respiratory rate in the VATS-e group was significantly less than that in the OS group on PODs 3, 5, and 7. Although no difference was observed in the frequencies of postoperative complications between the 2 groups, the VATS-e group had less postoperative pneumonia. VATS-e attenuates postoperative SIRS, and is therefore a potentially less invasive operative procedure. Copyright © 2012 Mosby, Inc. All rights reserved.

    Objective:To determine the clinical serum levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9), individually and in combination, for the diagnosis of 50 healthy subjects and 150 cases of esophageal, gastric, and colon cancers. Methods:The sensitivities of the two markers were compared individually and in combination, with specificity set at 100%. Receiver operating characteristic (ROC) curves were plotted. Results:Serum CEA levels were significantly higher in cancer patients than in the control group. The sensitivity of CEA was determined:in esophageal cancer, sensitivity=28%, negative predictive value (NPV)=61.72%, and AUC=0.742 (SE=0.05), with a significance level of P Conclusion:CEA exhibited the highest sensitivity for colon cancer, and CA19-9 exhibited the highest sensitivity for gastric cancer. Combined analysis indicated an increase in diagnostic sensitivity in esophageal and gastric cancer compared with that in colon cancer.

    Full Text Available Objective  To further investigate the diagnostic pitfalls of Kimura's disease(KD. Methods  We report one case of Kimura's disease accompanied with mediastinal lymphadenopathy admitted to General Hospital of Chinese PLA in the year 2010. After searching on PubMed and Chinese Medical Journal Searching Engines(Wanfang data base,Cqvip data base,we have found literatures reporting another 3 cases of Kimura's disease with mediastinal lymphadenopathy. Plus the one we presented, all four patients' clinical data were collected and analyzed thereafter. Up-to-date advancement on KD's diagnosis and therapy would also be reviewed. Results  Our case, a 61-year-old male, was initially misdiagnosed as lung cancer with mediastinal metastasis in 2008, but histopathology had confirmed only eosinophil infiltration in enlarged mediasinal lymph nodes, no malignant cells were identified. In the year 2010, he complained bilateral orbital masses, one of which was surgically removed, and was later confirmed as Kimura's disease by histopathology. Clinical features of 4 patients, including our case and the other 3 retrieved in literatures, were available, 2 of whom were misdiagnosed as lung cancer while the other 2 as lymphoma in the beginning. All the 4 patients were responsive to steroid therapy. Conclusions  Kimura's disease could be associated with mediastinal lymphadenopathy which may confuse the physicians in diagnosing. Newly developed minimal invasive approaches such as endoscopic ultrasound-guided fine needle aspiration (EUS-FNA and endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA are helpful for the differential diagnosis.

    The positive expression of MMP-2 and TIMP-2 were found in esophageal cancer (EC) tissue and correlated with cancer stage and clinico-pathological features of tumor and patients' survival. However, little is known about serum levels of those proteins in EC patients. The aim of the present study was to investigate the diagnostic significance of MMP-2 and TIMP-2 serum levels in EC patients in relation to clinico-pathological features of cancer. The study included 53 EC patients and 92 healthy controls. The serum levels of MMP-2, TIMP-2 and classical tumor markers CEA (carcinoembryonic antigen) and SCC (squamous cell carcinoma antigen) were assayed. The prognostic values and diagnostic criteria for the biomarkers tested were defined. Serum levels of MMP-2, TIMP-2 in EC patients were significantly lower, whereas CEA and SCC significantly higher than in control group. The diagnostic sensitivity of TIMP-2 (57%) was higher than those for other biomarkers tested and increased in combination with SCC (70%). Area under ROC curve for TIMP-2 (0.8698) was larger than for other proteins. In Cox's univariate analysis only SCC serum levels were significant prognostic factors for EC patients' survival. The results suggest the limited value of serum analyses of MMP-2 for tumor staging and prognosis in EC and the better usefulness of TIMP-2 than MMP-2 as a tumor marker in the diagnosis of EC, especially in combined use with SCC.

    The asymptomatic nature of esophageal cancer (EC) at early stages results in late clinical presentation leading to poor prognosis and limited success of therapeutic modalities. Efforts to identify diagnostic/prognostic markers have proven to be unsuccessful for translation into clinics. Hence, there is a pressing need for establishment of novel non-invasive biomarker for early diagnosis/better prognosis of EC. Recently, alteration in microRNA (miRNA) expression has emerged as an important hallmark of cancer. This review summarizes the differential expression of miRNAs in EC and addresses how their aberrant expression influences crucial biological processes such as apoptosis, cell proliferation, invasion and metastasis. Additionally, this review highlights the current status of circulating miRNA based diagnostic/prognostic markers. An effort has been made to find a connection between different miRNAs involved in EC and a detailed analysis has been done to screen out micoRNAs involved in prognosis and multidrug resistance. Further, investigation of these miRNAs would not only provide a gene therapy based strategy to prevent/treat cancer but also to reverse multidrug resistance leading to decreased requirement of harmful chemotherapeutic drugs.

    Cancer-testis (CT) antigens are attractive tumor antigens for cancer immunotherapy. They comprise a group of proteins normally expressed in germ cells and aberrantly activated in a variety of human cancers. The protein expression of eight cancer-testis antigens [MAGEA, NY-ESO-1, GAGE, MAGEC1 (CT7), MAGEC2 (CT10), CT45, SAGE1, and NXF2] was evaluated by immunohistochemistry in 61 esophageal carcinomas (40 adenocarcinoma and 21 squamous cell carcinoma), 50 gastric carcinomas (34 diffuse and 16 intestinal type), and 141 colorectal carcinomas. The highest frequency of expression was found in esophageal squamous cell carcinomas: Positive staining for MAGEA, CT45, CT7, SAGE1, GAGE, NXF2, NY-ESO-1, and CT10 was observed in 57%, 38%, 33%, 33%, 29%, 29%, 19%, and 14% of squamous cell carcinomas, respectively. Similar staining patterns were observed in squamous dysplasias. Expression frequencies of cancer-testis antigens were seen in 2% to 24% of gastroesophageal adenocarcinomas and were not significantly different between adenocarcinomas of the stomach versus the esophagus, or between diffuse and intestinal types of gastric adenocarcinomas. Colorectal cancers did not express NY-ESO-1, CT7, CT10, or GAGE, and only infrequently expressed SAGE1 (0.7%) MAGEA (1.4%), CT45 (3.5%), and NXF2 (8.5%). We conclude that cancer-testis antigens are frequently expressed in esophageal squamous neoplasms. Although cancer-testis antigens are generally considered to be expressed later in tumor progression, they are found in squamous dysplasias, suggesting a potential diagnostic role for cancer-testis antigens in the evaluation of premalignant squamous lesions.

    Radial forearm free flap (RFFF)-accompanied phonation tube (PT) for voice and speech restoration after pharyngolaryngectomy is promising, especially in phonation efficacy and intelligibility. It offers not only another safe surgical option but also a satisfactory result for such patients with advanced hypopharyngeal cancer. We use RFFF with RFFF-accompanied PT for one-stage reconstruction both for tissue defect and voice reconstruction in patients undergoing total pharyngolaryngectomy. Eight male patients with advanced hypopharyngeal cancer underwent total pharyngolaryngectomy. Voice restoration was done with RFFF-accompanied PT. Phonation outcomes and speech outcomes of the patients were evaluated and scored. The mean follow-up time was 13.7 months. All free flaps were successful without perioperative mortality. All the patients were able to produce sound. Phonation efficacy ranged from 70% to >90% postoperatively and 40% to >90% at the last follow-up. The speech intelligibility was graded as moderately good.

    @@ Surgical complications after the transthoracic operation for esophageal cancer mainly include anastomatic fistula, thoraco-stomach fistula, stenosis of anastomosis,gastric perforation, gastric volvulus, diaphragmatic hernia,wound infection, and some other pulmonary complications. Unfortunately, there are few reports about the complications caused by position change of the chest tube until now. We presented an unusual case of a patient who underwent a transthoracic operation for esophageal cancer in our department on August 17, 2006, and a lot of intragastric material was found in his chest tube 17 days later, endoscopic examination suggested that the chest tube had inserted into the stomach. We tried to discuss the etiology and clinical management for this case as well.

    The management of postoperative leaks into the mediastinum after esophagectomy remains a challenge.We describe our clinical management of this complication through endoscopic transluminal drainage.Between 2008 and 2011,4 patients with esophageal squamous cell carcinoma (ESCC) who underwent McKeown-type esophagectomy with two-field lymphadenectomy experienced complicated anastomotic fistulae in the presence of superior mediastinal sepsis.All 4 patients underwent endoscopic transluminal drainage,and all survived.The mean healing period was 50 days (range,31 to 58 days),the mean stay in the intensive care unit was 7.3 days (range,1 to 18 days),and the mean hospital stay was 64.5 days (range,49 to 70 days).Endoscopically guided transluminal drainage should be considered for ESCC patients with superior mediastinal fistulae after esophagectomy.

    This study was aimed to investigate the functional roles of cytokine receptor (CXCR) CXCR2 and CXCR7 in esophageal cancer (EC). Specific small interfering RNAs (siRNA) against CXCR2 and CXCR7 were transfected into EC cell lines TE-1, EC9706, and EC109 cells. Expression of CXCR2 and CXCR7 was validated, along with cell viability, chemotaxis, apoptosis rate, and ERK1/2 pathways associated protein after transfection. Moreover, EC9706 cells treated with or without CXCR2/7 siRNA were injected into athymic nude mice. Tumor volumes were measured. Besides, immunohistochemical (IHC) staining was performed to investigate the expression of CXCR2/7 in adjacent normal tissues and tumor tissues from esophageal squamous cell carcinoma (ESCC) patients. Also, the associations between CXCR2/7 expression and clinicopathological features and progression were explored. The mRNA levels of CXCR2 and CXCR7 were significantly reduced after transfection. Silencing of CXCR2 and CXCR7 statistically decreased cell viability and chemotaxis, and increased apoptotic rate. Cells invasion was significantly reduced by silencing of CXCR2, however, no significance was found in silencing of CXCR7. The protein levels of pERK1/2 were significantly decreased by silencing of CXCR2 and CXCR7. Besides, silencing of CXCR2 and CXCR7 significantly reduced tumor growth in vivo, and associated with clinicopathological features and progression. Silencing of CXCR2 and CXCR7 protects against EC by inhibiting cell growth and chemotaxis, and inducing apoptosis though ERK1/2 pathways. Silencing of CXCR2 and CXCR7 has potentially therapeutic target for EC. PMID:27648130

    In the past 30 years, the incidence of esophageal adenocarcinoma (EAC) has increased more rapidly than any other cancer in the United States. The prevalence of obesity and diabetes mellitus has drastically increased as well. We explored the potential association between obesity, diabetes mellitus, and EAC. By means of retrospective interrogation of an administrative database from fiscal year 2005-2009, we identified two cohorts. The cancer cohort was defined as patients with adenocarcinoma of the distal esophagus or gastric cardia. The comparison cohort contained patients with gastroesophageal reflux disorder (GERD; diagnosis coupled with a procedure code for fundoplication). Patient data, including demographic measures, diagnoses of obesity, diabetes mellitus, dyslipidemia, alcohol abuse, and nicotine dependence were examined. A logistic regression model identified risk factors for development of EAC. The sample included 2,836 patients identified as having either EAC (1,704) or fundoplication with GERD (1,132). Although slightly higher percentages of the benign cohort were obese, the cancer cohort had more diabetics (30.8% vs. 14.8%; chi-square = 94.5; P cancer as opposed to GERD without cancer (OR = 2.2; 95% confidence interval [CI] 1.7-2.8). Nicotine dependence was also identified as a risk factor (OR = 1.7; 95% CI 1.4-2.0). We identified a potential association between diabetes mellitus and adenocarcinoma of the esophagus or gastric cardia. This association appears to be independent of obesity. Additionally, nicotine dependence was identified as a risk factor for EAC. © 2015 International Society for Diseases of the Esophagus.

    No definitive operative method has been established for the treatment of early subcardial gastric cancer. Our newly developed technique involves local resection of the subcardia while preserving the lower esophageal sphincter and vagus nerve. A new fornix is constructed to accept the transposed esophagus. Thirty patients underwent this procedure between July 2003 and December 2010. Continuous gastric pH monitoring was performed immediately after surgery, and esophageal manometry was undertaken 1 month later. Serum total protein, albumin, total cholesterol, cholinesterase, and body mass index (BMI) were recorded every 3 months. Pre- and postoperative oral intake were compared, reflux symptoms were recorded, and reflux esophagitis was assessed by endoscopy after 1 year. Twenty-five patients (86 %) reported no symptoms of reflux, and 27 (92.8 %) patients could eat 70 % or more of what they had eaten before surgery. Lower esophageal pressures were found to be >10 mmHg in 66.7 % of patients, and the fraction of time that pH <4 was <5 % of the 24-h monitoring period in 70 %. Serum parameters and BMI were unchanged. This surgical technique is a useful means of preserving postoperative quality of life after local gastrectomy by preventing reflux and maintaining nutritional status.

  14. An EGFR/HER2-Bispecific and enediyne-energized fusion protein shows high efficacy against esophageal cancer.

    Full Text Available Esophageal cancer is one of the most common cancers, and the 5-year survival rate is less than 10% due to lack of effective therapeutic agents. This study was to evaluate antitumor activity of Ec-LDP-Hr-AE, a recently developed bispecific enediyne-energized fusion protein targeting both epidermal growth factor receptor (EGFR and epidermal growth factor receptor 2 (HER2, on esophageal cancer. The fusion protein Ec-LDP-Hr-AE consists of two oligopeptide ligands and an enediyne antibiotic lidamycin (LDM for receptor binding and cell killing, respectively. The current study demonstrated that Ec-LDP-Hr had high affinity to bind to esophageal squamous cell carcinoma (ESCC cells, and enediyne-energized fusion protein Ec-LDP-Hr-AE showed potent cytotoxicity to ESCC cells with differential expression of EGFR and HER2. Ec-LDP-Hr-AE could cause significant G2-M arrest in EC9706 and KYSE150 cells, and it also induced apoptosis in ESCC cells in a dosage-dependent manner. Western blot assays showed that Ec-LDP-Hr-AE promoted caspase-3 and caspase-7 activities as well as PARP cleavage. Moreover, Ec-LDP-Hr-AE inhibited cell proliferation via decreasing phosphorylation of EGFR and HER2, and further exerted inhibition of the activation of their downstream signaling molecules. In vivo, at a tolerated dose, Ec-LDP-Hr-AE inhibited tumor growth by 88% when it was administered to nude mice bearing human ESCC cell KYSE150 xenografts. These results indicated that Ec-LDP-Hr-AE exhibited potent anti-caner efficacy on ESCC, suggesting it could be a promising candidate for targeted therapy of esophageal cancer.

    Background: To characterize the potential function and clinical significance of Transketolase (TKT) in esophageal cancer. Methods: High invasive esophageal squamous cell carcinoma (ESCC) cell line CE48T/VGH was used. Cellular functions in response to TKT modulation were examined, including cell growth, migration and invasion. The underlying molecules involved in the TKT regulatory mechanism were determined by western blot and confocal microscopic analysis. Clinically, TKT expressions in 76 ESCC patients were assessed by immunohistochemical (IHC) method, and the association with treatment outcome was determined. Results: TKT silencing inhibited cell migration and invasion but had a minimal effect on cell growth. This TKT silencing also induced the reversion of epithelial-mesenchymal transition (EMT), as evidenced by the spindle to cuboidal morphological change, increased the expression of epithelial markers (γ-catenin), and decreased the levels of mesenchymal markers (fibronectin and N-cadherin). Mechanically, TKT was shown to modulate the EMT through the pERK-Slug/Snail-associated signaling pathway. Clinically, a high level of TKT in the cancer tissues of patients with esophageal squamous cell carcinoma was associated with poor survival (P = 0.042). In the multivariate analysis, a high TKT level was also shown to be an independent unfavorable prognostic factor (Odds ratio: 1.827, 95% confidence interval: 1.045-3.196, P = 0.035). Conclusions: TKT contributes to esophageal cancer by promoting cell invasion via meditating EMT process. Clinically, the over-expression of TKT in ESCC patients predicts poorer survival. TKT inhibition may be a useful strategy to intervene in cancer cell invasion and metastasis, which may lead to better prognosis for ESCC patients. PMID:27698919

    Esophagectomy for cancer can be performed in a two-stage procedure with an intrathoracic anastomosis: the Ivor Lewis esophagectomy. A growing incidence of distal and gastroesophageal junction adenocarcinomas and increasing use of minimally invasive techniques have prompted interest in this procedure. The aim of this study was to assess short-term results of minimally invasive Ivor Lewis esophagectomy (MIE-IL). A retrospective cohort study was performed from June 2007 until September 2014, including patients that underwent MIE-IL for distal esophageal and gastroesophageal junction cancer in six different hospitals in the Netherlands and Spain. Data were collected with regard to operative techniques, pathology and postoperative complications. In total, 282 patients underwent MIE-IL, of which 90.2 % received neoadjuvant therapy. Anastomotic leakage was observed in 43 patients (15.2 %), of whom 13 patients (4.6 %) had empyema, necessitating thoracotomy for decortication. With an aggressive treatment of complications, the 30-day and in-hospital mortality rate was 2.1 %. An R0-resection was obtained in 92.5 % of the patients. After neoadjuvant therapy, 20.1 % of patients had a complete response. Minimally invasive Ivor Lewis esophagectomy for distal esophageal and gastroesophageal junction adenocarcinomas is an upcoming approach for reducing morbidity caused by laparotomy and thoracotomy. Anastomotic leakage rate is still high possibly due to technical diversity of anastomotic techniques, and a high percentage of patients treated by neoadjuvant chemoradiotherapy. An aggressive approach to complications leads to a low mortality of 2.1 %. Further improvement and standardization in the anastomotic technique are needed in order to perform a safe intrathoracic anastomosis.

    Highlights: {yields} Loss of MUC4 reduces proliferation of esophageal cancer cells. {yields} MUC4 inhibition impairs migration of esophageal cancer cells but not their invasion. {yields} Loss of MUC4 significantly reduces in vivo tumor growth. {yields} Decrease of S100A4 induced by MUC4 inhibition impairs proliferation and migration. -- Abstract: MUC4 is a membrane-bound mucin known to participate in tumor progression. It has been shown that MUC4 pattern of expression is modified during esophageal carcinogenesis, with a progressive increase from metaplastic lesions to adenocarcinoma. The principal cause of development of esophageal adenocarcinoma is the gastro-esophageal reflux, and MUC4 was previously shown to be upregulated by several bile acids present in reflux. In this report, our aim was thus to determine whether MUC4 plays a role in biological properties of human esophageal cancer cells. For that stable MUC4-deficient cancer cell lines (shMUC4 cells) were established using a shRNA approach. In vitro (proliferation, migration and invasion) and in vivo (tumor growth following subcutaneous xenografts in SCID mice) biological properties of shMUC4 cells were analyzed. Our results show that shMUC4 cells were less proliferative, had decreased migration properties and did not express S100A4 protein when compared with MUC4 expressing cells. Absence of MUC4 did not impair shMUC4 invasiveness. Subcutaneous xenografts showed a significant decrease in tumor size when cells did not express MUC4. Altogether, these data indicate that MUC4 plays a key role in proliferative and migrating properties of esophageal cancer cells as well as is a tumor growth promoter. MUC4 mucin appears thus as a good therapeutic target to slow-down esophageal tumor progression.

    We sought to determine the response rate and toxicity profile of sequential paclitaxel and bryostatin-1, a novel, selective inhibitor of protein kinase C, in patients with advanced esophageal cancer. Patients with advanced esophageal and gastroesophageal junction cancer were enrolled. All gave informed consent. They were initially treated with paclitaxel 90 mg/m(2) intravenously on Day 1 and bryostatin-1 50 microg/m2 on Day 2 weekly for three consecutive weeks out of four. Because of severe myalgias, dosing was reduced to paclitaxel 80 mg/m2 with bryostatin-1 40 microg/m2 and then to paclitaxel 80 mg/m2 with bryostatin-1 25 microg/m2. Twenty-four patients were enrolled, with 22 assessable for response. The partial response rate was 27%. 10 patients treated with bryostatin-1 40-50 microg/m2 had a response rate of 40 versus 17% at bryostatin-1 25 microg/m2 (p-value = 0.3). Median time-to-progression was 3.7 months and median survival was 8.3 months. Grade 3/4 myalgias were seen in 50% of patients. Myalgias appeared to be related to bryostatin-1 dose. Because of toxicity, the trial was closed prior to full accrual. Despite potential anti-tumor activity of this combination in patients with advanced esophageal cancer, further development is not warranted, given the severe toxicity, especially myalgias, that were seen.

    We investigated the effects of stathmin 1 (STMN1) silencing by small interfering (siRNA) on the sensitivity of esophageal cancer cells Eca-109 to paclitaxel. STMN1 siRNA was transiently transfected into Eca-109 cells. The effects of transfection were detected by quantitative polymerase chain reaction and western blotting. The effects of STMN1 silencing by siRNA on the sensitivity of esophageal cancer cells Eca-109 to paclitaxel was tested by MTT and colony formation assays. Hoechst 33258 nuclear staining was used to investigate the differences in Eca-109 cell apoptosis induced by paclitaxel. STMN1 siRNA was successfully transfected and the expression of STMN1 was inhibited. The sensitivity of STMN1 siRNA-transfected Eca-109 cells to paclitaxel was significantly increased (P < 0.01). The apoptosis of Eca-109 cells significantly increased following treatment with paclitaxel (P < 0.01). STMN1 silencing by siRNA may enhance the sensitivity of esophageal cancer cells Eca-109 to paclitaxel and induce apoptosis.

    This study examined the effects of a psychological nursing intervention on personality characteristics and quality of life of esophageal cancer patients. Esophageal cancer patients (n=86) were randomized into either an intervention group (n=45) or a control group (n=41). Patients in the control group were given routine nursing care, and those in the intervention group were provided with psychological nursing interventions in addition to routine nursing care. Personality characteristics, assessed through Eysenck Personality Questionnaire, and quality of life, assessed through EORTC QLQ-C30, were compared between the two groups. The results showed that personality characteristics were closely related to quality of life. After the psychological nursing intervention, the main factors were neurosis, psychosis or mood instability, and personality stability. However, introverted and extroverted personality characteristics were not associated with quality of life. The psychological nursing intervention was associated with decreased P-scale and E-scale scores of personality characteristics and improved quality of life in each dimension scored. A psychological nursing intervention can affect the personality characteristics of esophageal cancer patients and improve their quality of life; this approach is worthy of further study and clinical application.

    Purpose: to study efficacy and toxicity of radiochemotherapy in esophageal cancer including initial endoluminal high-dose-rate brachytherapy (HDR-BT). Patients and methods: between 01/1995 and 06/2005, 61 patients with esophageal cancer were treated preoperatively with definitive and palliative intent. Treatment started with intraluminal HDR-BT for recanalization of the esophagus (single fraction size of 8 Gy in 0.5 cm depth, three times, q7d) followed by external-beam radiation therapy (50 Gy total dose, 5 x 2 Gy/week, 25 fractions in 5 weeks). Chemotherapy was started simultaneously with external irradiation (three courses of cisplatin and 5-fluorouracil, q21d). Results: swallowing function improved in 55/61 patients (dysphagia classification according to the RTOG), and worsened in 6/61 patients, respectively. Median duration of symptomatic improvement was 11 months, median follow-up 12 months (range 3-68 months). Following simultaneous radiochemotherapy, tumor resectability was achieved in 7/25 patients of the neoadjuvant group, and the histological specimen showed complete remission in 6/7 patients. Conclusion: these results indicate a favorable effect of simultaneous radiochemotherapy starting with endoluminal HDR-after-loading-(AL-)BT in esophageal cancer. (orig.)

    Purpose: To develop a 4DCT robust optimization method to reduce the dosimetric impact from respiratory motion in intensity modulated proton therapy (IMPT) for esophageal cancer. Methods: Four esophageal cancer patients were selected for this study. The different phases of CT from a set of 4DCT were incorporated into the worst-case dose distribution robust optimization algorithm. 4DCT robust treatment plans were designed and compared with the conventional non-robust plans. Result doses were calculated on the average and maximum inhale/exhale phases of 4DCT. Dose volume histogram (DVH) band graphic and ΔD95%, ΔD98%, ΔD5%, ΔD2% of CTV between different phases were used to evaluate the robustness of the plans. Results: Compare to the IMPT plans optimized using conventional methods, the 4DCT robust IMPT plans can achieve the same quality in nominal cases, while yield a better robustness to breathing motion. The mean ΔD95%, ΔD98%, ΔD5% and ΔD2% of CTV are 6%, 3.2%, 0.9% and 1% for the robustly optimized plans vs. 16.2%, 11.8%, 1.6% and 3.3% from the conventional non-robust plans. Conclusion: A 4DCT robust optimization method was proposed for esophageal cancer using IMPT. We demonstrate that the 4DCT robust optimization can mitigate the dose deviation caused by the diaphragm motion.

    Dysphagia is a common initial presentation in locally advanced esophageal cancer and negatively impacts patient quality of life and treatment compliance. To induce fast relief of dysphagia in patients with potentially operable esophageal cancer high-dose-rate (HDR) brachytherapy was applied prior to definitive radiochemotherapy. In this single arm phase II clinical trial between 2013 to 2014 twenty patients with locally advanced esophageal cancer (17 squamous cell and 3 adenocarcinoma) were treated with upfront 10 Gy HDR brachytherapy, followed by 50.4 Gy external beam radiotherapy (EBRT) and concurrent chemotherapy with cisplatin/5-fluorouracil. Tumor response, as measured by endoscopy and/or computed tomography scan, revealed complete remission in 16 and partial response in 4 patients (overall response rate 100%). Improvement of dysphagia was induced by brachytherapy within a few days and maintained up to the end of treatment in 80% of patients. No differences in either response rate or dysphagia resolution were found between squamous cell and adenocarcinoma histology. The grade 2 and 3 acute pancytopenia or bicytopenia reported in 4 patients, while sub-acute adverse effects with painful ulceration was seen in five patients, occurring after a median of 2 months. A perforation developed in one patient during the procedure of brachytherapy that resolved successfully with immediate surgery. Brachytherapy before EBRT was a safe and effective procedure to induce rapid and durable relief from dysphagia, especially when combined with EBRT.

    Human esophageal cancers have been shown to express high levels of epidermal growth factor receptor (EGFR and a relationship between high EGFR expression and local advance, the number of lymph node metastases, life expectancy, and sensitivity to chemo-radiotherapy has been demonstrated. We examined the use of gefitinib, an orally active EGFR-selective tyrosine kinase inhibitor, as a new strategy for treatment of esophageal carcinoma. The effects of gefitinib were evaluated in monotherapy and in combination with radiotherapy in human esophageal carcinoma cell lines. Gefitinib produced a dose-dependent inhibition of cellular proliferation in all of the 8 esophageal carcinoma cell lines examined, with IC50 values ranging from 5.7 microM to 36.9 microM. In combination, gefitinib and radiotherapy showed a synergistic effect in 2 human esophageal carcinoma cell lines and an additive effect in 5 cell lines. Western blotting demonstrated that gefitinib blocked activation of the EGFR-extracellular signal-regulated kinase (Erk pathway and the EGFR-phosphoinositide-3 kinase (PI3K-Akt pathway after irradiation. These results suggest that further evaluation of EGFR blockade as a treatment for esophageal cancer should be performed, and that radiotherapy combined with EGFR blockade may enhance the response of esophageal carcinoma to therapy.

    Genetic abnormalities of proto-oncogenes and tumor suppressor genes have been demonstrated to be changes that are frequently involved in esophageal cancer pathogenesis. However, hypermethylation of CpG islands, an epigenetic event, is coming more and more into focus in carcinogenesis of the esophagus. Recent studies have proved that promoter hypermethylation of tumor suppressor genes is frequently observed in esophageal carcinomas and seems to play an important role in the pathogenesis of this tumor type. In this review, we will discuss current research on genes that are hypermethylated in human esophageal cancer and precancerous lesions of the esophagus. We will also discuss the potential use of hypermethylated genes as targets for detection, prognosis and treatment of esophageal cancer.

    Irisin is a novel hormone that has been proposed to mediate the beneficial effects of exercise on metabolism, including body weight regulation and insulin resistance. No previous studies have evaluated whether irisin may regulate cell proliferation and malignant potential of obesity-related cancer cell lines. Cell proliferation and malignant potential i.e. cell adhesion and colony formation were studied in vitro using human and mouse obesity-related cancer cell lines i.e. endometrial (KLE and RL95-2), colon (HT29 and MCA38), thyroid (SW579 and BHP7) and esophageal (OE13 and OE33). We observed that, in contrast to metformin, cell proliferation is not regulated by irisin in a dose-dependent manner in human and mouse obesity-related cancer cell lines. Specifically, physiological (5 to 10 nmol/L) and high physiological/pharmacological (50 to 100 nmol/L) concentrations of irisin had no effect on cell proliferation when compared to control in human and mouse endometrial, colon, thyroid and esophageal cancer cell lines. Also, we observed that, in contrast to metformin, neither physiological nor high physiological/pharmacological concentrations of irisin regulate cell adhesion and/or colony formation in human and mouse endometrial, colon, thyroid and esophageal cancer cell lines. Our data suggest that irisin, in physiological and high physiological/pharmacological concentrations, has no in vitro effect on cell proliferation and malignant potential of obesity-related cancer cell lines. Future work is needed to determine the regulation of irisin levels and any physiological effects it may have on obesity-related cancers in vivo in animals and humans. © 2013.

    Anyang is known to be a high-incidence area of esophageal cancer (EC) in China. Among a long list of risk factors, the quality of drinking water was evaluated. We have selected 3806 individuals and collected 550 drinking water samples correspondent with this not-matched case-control survey. There are 531 EC patients included based on Population Cancer Registry from 92 townships, of which 3275 controls with long-lived aged over 90 years and free from EC are used as controls in the same regions. Our result suggests that the quality of drinking water is a highly associated risk factor for EC. The residential ecological environment and the quality of water resource positively link with each other. The analysis of water samples also demonstrated that the concentrations of methyl ethylamine, morpholine, N-methylbenzylamine, nitrate and chloride in water from springs and rivers are higher than those in well and tap water (P = 0.001). Micronuclei formation tests show that well water and tap water in these regions have no mutagenicity.

    In the seventh edition of the Union for International Cancer Control (UICC) TNM classification, supraclavicular lymph node (SCLN) in regard to thoracic esophageal cancer (EC) is regarded as a distant organ, therefore, if resectable, SCLN metastasis is considered a candidate for systemic chemotherapy. The purpose of this study was to clarify the survival outcome in patients with resectable thoracic EC with SCLN metastases (M1LYM) treated with curative intent. Clinical outcomes in patients with resectable thoracic EC with SCLN metastases (M1LYM) treated by esophagectomy or definitive chemoradiotherapy (dCRT) were retrospectively analyzed. A total of 102 patients were divided in three groups: Surgery with perioperative therapy, n=45; surgery alone, n=19; and dCRT, n=38. Overall, median progression-free survival and median survival time were 9.3 and 26.7 months, respectively. The median survival time was 27.5 months in the group treated with surgery with perioperative treatment, 50.6 months in those treated with surgery alone, and 22 months in the dCRT group. No significant survival difference was seen among the three groups. Over 30% of patients with resectable M1LYM treated with curative intent achieved long-term survival.

    To explore the relationships between esophageal cancer (EC) and climatic, geographic factors in China by using Geographic Information System, database of EC mortality of 237 sampling areas surveyed in 1990-1992 was established in Excel and linked with the digital polygon maps of study areas. Geographic and climate data of sampling areas were extracted from the raster dataset and finished in Arc/Info 9.0 and ENVI4.2 software by using spatial analysis. Spearman correlation analysis and multiple regression analysis after principal component analysis (PCA) were performed to analyze the relationship between EC and these factors. The counties that have the highest EC morality show significant aggregation. Spearman correlation analysis shows weak negative correlation between precipitation, water-heat index (WHI), highest/lowest temperature and EC mortality, and weak positive correlation between drought index (DI), wind speed, population density and EC mortality. Multiple linear regression analysis indicated that the variables associated with EC mortality were precipitation, temperature, wind speed, elevation, DI, WHI and normalized difference vegetation index (NDVI) of July. Our study suggested that the high-risk areas of EC in China are mostly drought and low altitude areas relatively. There were relatively lower NDVI in summer and higher wind speed in these areas. GIS can be applied to cancer epidemiology study and will exert active effect, which should be further explored.

    Target volume definition in modern radiotherapy is based on planning computed tomography (CT). So far, 18-fluorodeoxyglucose positron emission tomography (FDG-PET) has not been included in planning modality in volume definition of esophageal cancer. This study evaluates fusion of FDG-PET and CT in patients with esophageal cancer in terms of geographic misses and inter-observer variability in volume definition. In 28 esophageal cancer patients, gross, clinical and planning tumor volumes (GTV; CTV; PTV) were defined on planning CT by three radiation oncologists. After software-based emission tomography and computed tomography (PET/CT) fusion, tumor delineations were redefined by the same radiation-oncologists. Concordance indexes (CCI's) for CT and PET/CT based GTV, CTV and PTV were calculated for each pair of observers. Incorporation of PET/CT modified tumor delineation in 17/28 subjects (61%) in cranial and/or caudal direction. Mean concordance indexes for CT-based CTV and PTV were 72 (55-86)% and 77 (61-88)%, respectively, vs. 72 (47-99)% and 76 (54-87)% for PET/CT-based CTV and PTV. Paired analyses showed no significant difference in CCI between CT and PET/CT. Combining FDG-PET and CT may improve target volume definition with less geographic misses, but without significant effects on inter-observer variability in esophageal cancer.

    Background Feicheng County is a high-risk area for esophageal cancer in Shandong province, China. It is important to determine the long-term spatio-temporal trends in epidemiological characteristics and the burden of esophageal cancer, especially since the implementation of the national esophageal cancer screening program for early detection and treatment in 2005. Methods The data collected in Feicheng County from 2001 to 2012 was extracted from the whole-population cancer registry system. The incidence, mortality, disability-adjusted life years (DALY) and changing trends in esophageal cancer according to age and sex were calculated and described. Results The incidence rate of esophageal cancer in Feicheng was consistently high, and increased significantly for male, but not for female from 2001 to 2012, according to the joinpoint regression analysis. The highest and lowest yearly crude incidence rates were 160.78 and 95.97 per 100000 for males, and 81.36 and 52.17 per 100000 for females. The highest and lowest crude yearly mortality rates were 122.26 and 94.40 per 100000 for males, and 60.75 and 49.35 per 100000for females. Esophageal squamous cell carcinoma was the main pathology type and the tumor location changed significantly from 2001 to 2012. Overall, the DALY remained roughly stable and was estimated as 11.50 for males and 4.90 for females per 1000 people. The burden was mainly caused by premature death. There is an obvious spatial pattern in the distribution of incidence density and burden. Conclusion Esophageal cancer remains a public health issue in Feicheng County with a high incidence, mortality and disease burden. The incidence and burden have obvious spatial heterogeneity, and further studies should be conducted to identify geographical risk factors for precise local prevention and control measures.

    Full Text Available Abstract Background The diagnosis of lymph node metastasis in esophageal cancer by the presence and number of metastatic lymph nodes is an extremely important prognostic factor. In addition, the indication of non-surgical therapy is gaining more attention. Vascular endothelial growth factor C (VEGF-C is potentially lymphangiogenic and selectively induces hyperplasia of the lymphatic vasculature. In this study, we investigated the expression of VEGF-C and whether it correlated with various clinico-pathologic findings. Methods KYSE series of esophageal cancer cell lines and 106 patients with primary esophageal squamous cell carcinomas who had undergone radical esophagectomy were analyzed. VEGF-C mRNA expression was determined by quantitative RT-PCR. Results High expression of VEGF-C was detected in most of the KYSE cell lines, especially KYSE410, yet, in an esophageal normal epithelium cell line, Het-1A, VEGF-C was not detected. In the clinical specimen, the expression of VEGF-C in the cancerous tissue was higher than in the corresponding noncancerous esophageal mucosa (p = 0.026. The expression of VEGF-C was found to be higher in Stage2B-4A tumors than in Stage0-2A tumors (p = 0.049. When the patients were divided into two groups according to their expression levels of VEGF-C (a group of 53 cases with high expression and a group of 53 cases with low expression, the patients with high VEGF-C expression had significantly shorter survival after surgery than the patients with low expression (p = 0.0065. Although univariate analysis showed that high expression of VEGF-C was a statistically significant prognostic factor, this was not shown in multivariate analysis. In the subgroup of patients with Tis and T1 tumors, the expression of VEGF-C was higher in N1 tumors than in N0 tumors (p = 0.029. The survival rate of patients from the high expression group (n = 10 was lower than that in the low expression group (n = 11, and all the patients in the low

    Human papillomavirus (HPV) is a risk factor for head and neck squamous cell carcinoma (HNSCC) as well as esophageal squamous cell carcinoma (ESCC). We aimed to investigate whether HPV infection underlies the field cancerization phenomenon over upper aerodigestive tract to develop synchronous multiple cancers. A case control study. The presence and subtype of HPV-DNA sequence in cancers were examined by polymerase chain reaction and sequencing in a prospective cohort with 100 HNSCCs, 50 of which had synchronous ESCCs. The clinicopathologic characteristics were further analyzed according to the presence of HPV. Twelve patients were HPV-positive, of which 11 were positive for HPV-16. The prevalence of HPV infection were not different between the synchronous and HNSCC alone groups (P = 0.357). Testing for HPV in paired HNSCC and ESCC tissues from the same patient revealed that none were concomitantly HPV-positive. Multivariate logistic regression showed drinking alcohol (odds ratio [OR], 18.75; P = 0.030), alcohol flushing (OR, 2.53; P = 0.041), and body mass index (OR, 0.77; P = 0.001) but not HPV infection were independent risk factors for synchronous phenotype. The patients with synchronous ESCCs had significantly poorer survival than those with HNSCC alone (5-year overall survival: 30% vs. 70%; log-rank P infection plays little role in field cancerization phenomenon to initiate synchronous SCC. The synchronous HNSCC and ESCC from the same patients had no clonal relationship. Routine endoscopic examination of the esophagus should be recommended for patients with risk factors identified. NA.

    To evaluate the dose-volume parameters of the pericardium and heart in order to reduce the risk of radiation-induced pericardial effusion (PE) and symptomatic PE (SPE) in esophageal cancer patients treated with concurrent chemoradiotherapy. In 86 of 303 esophageal cancer patients, follow-up CT was obtained at least 24 months after concurrent chemoradiotherapy. Correlations between clinical factors, including risk factors for cardiac disease, dosimetric factors, and the incidence of PE and SPE after radiotherapy were analyzed using Cox proportional hazard regression analysis. Significant dosimetric factors with the highest hazard ratios were investigated using zones separated according to their distance from esophagus. PE developed in 49 patients. Univariate analysis showed the mean heart dose, heart V{sub 5}-V{sub 55}, mean pericardium dose, and pericardium V{sub 5}-V{sub 50} to all significantly affect the incidence of PE. Additionally, body surface area was correlated with the incidence of PE in multivariate analysis. Grade 3 and 4 SPE developed in 5 patients. The pericardium V{sub 50} and pericardium D{sub 10} significantly affected the incidence of SPE. The pericardium V{sub 50} in patients with SPE ranged from 17.1 to 21.7%. Factors affecting the incidence of SPE were the V{sub 50} of the pericardium zones within 3 cm and 4 cm of the esophagus. A wide range of radiation doses to the heart and pericardium were related to the incidence of PE. A pericardium V{sub 50} ≤ 17% is important to avoid symptomatic PE in esophageal cancer patients treated with concurrent chemoradiotherapy. (orig.)

    Full Text Available Abstract Background Photodynamic therapy (PDT is a less invasive and effective salvage treatment for local failure after chemoradiotherapy (CRT for esophageal cancer, however it causes a high rate of skin phototoxicity and requires a long sun shade period. Talaporfin sodium is a rapidly cleared photosensitizer that is expected to have less phototoxicity. This study was undertaken to clarify the optimum laser fluence rate of PDT using talaporfin sodium and a diode laser for patients with local failure after CRT or radiotherapy (RT for esophageal cancer. Methods This phase I, laser dose escalation study used a fixed dose (40 mg/m2 of intravenous talaporfin sodium administered 4 to 6 hours before irradiation in patients with local failure limited to T2 after CRT or RT (≥ 50 Gy. The primary endpoint was to assess the dose limiting toxicity (DLT of PDT, and the secondary endpoints were to evaluate the adverse events and toxicity related to PDT. The starting fluence of the 664 nm diode laser was 50 J/cm2, with an escalation plan to 75 J/cm2 and 100 J/cm2. Results 9 patients with local failure after CRT or RT for ESCC were enrolled and treated in groups of 3 individuals to the third fluence level. No DLT was observed at any fluence level. Phototoxicity was not observed, but one subject had grade 1 fever, three had grade 1 esophageal pain, and 1 had grade 1 dysphagia. Five of 9 patients (55.6% achieved a complete response after PDT. Conclusions PDT using talaporfin sodium and a diode laser was safe for local failure after RT in patients with esophageal cancer. The recommended fluence for the following phase II study is 100 J/cm2.

    Full Text Available Prognosis of esophageal cancer patients can be significantly improved by neoadjuvant chemoradiotherapy (nCRT. Given the aggressive nature of esophageal tumors, it is conceivable that in a significant portion of patients treated with nCRT, dissemination already becomes manifest during the period of nCRT. The aim of this retrospective study was to determine the value and diagnostic accuracy of PET-CT after neoadjuvant chemoradiotherapy to identify patients with metastases preoperatively in order to prevent non-curative surgery.From January 2011 until February 2013 esophageal cancer patients deemed eligible for a curative approach with nCRT and surgical resection underwent a PET-CT after completion of nCRT. If abnormalities on PET-CT were suspected metastases, histological proof was acquired. A clinical decision model was designed to assess the cost-effectiveness of this diagnostic strategy.156 patients underwent a PET-CT after nCRT. In 31 patients (19.9% PET-CT showed abnormalities suspicious for dissemination, resulting in 17 cases of proven metastases (10.9%. Of the patients without proven metastases 133 patients were operated. In 6 of these 133 cases distant metastases were detected intraoperatively, corresponding to 4.5% false-negative results. The standard introduction of a post-neoadjuvant therapy PET-CT led to a reduction of overall health care costs per patient compared to a scenario without restaging with PET-CT ($34,088 vs. $36,490.In 10.9% of esophageal cancer patients distant metastases were detected by standard PET-CT after neoadjuvant chemoradiotherapy. To avoid non-curative resections we advocate post-neoadjuvant therapy PET-CT as a cost-effective step in the standard work-up of candidates for surgery.

    Objective: To discuss the epidemic strength of cardia and distant stomach cancers in the high risk region of esophageal cancer along the south Taihang mountain such as in Shexian, Linxian, and Cixian Counties, and to clarify the tasks for the control of upper gastrointestinal tract cancer as a whole in the region. Methods: Comparisons of incidence and mortality rates of esophageal, cardia and stomach cancers were made between Cixian, Linxian and Shexian Counties with reference to detection rates of cancer in situ and precancerous lesions of the three upper gastrointestinal cancers by endoscopic screening. The screening was performed from 1999 through 2004 in the three adjacent counties including a total of 6233 local residents aged 40 to 69 years old. Results: The incidence rates for cardia cancer for the male and female from 2000 through 2004 were 69.9 and 41.5, and the mortality rates were 54.3and 33.2 respectively in Shexian County. Esophageal, cardia, and stomach cancers constitute about 70~80 percent of all malignant disease by incidence or mortality rates. Endoscopic survey with iodine staining can effectively detect squamous cell precancerous lesions in the esophagus, but the method is inadequate for the detection of adeno precancerous lesions of the cardia and stomach. Conclusion: The south Taihang mountain region is a high risk area not only for esophagus cancer, but also for cardia and stomach cancers. To control upper gastrointestinal tract cancers as a whole in the region, special attention should be paid to the control of cardia and stomach cancers. Presently, to find effective screening methods for detecting cardia and stomach precancerous lesions is especially important.

    To investigate the survival status of patients with pharyngeal, laryngeal or cervical esophageal cancers, who received free jejunal flap (FJF) to repair the defects following tumor resection, and to analyze the effect of multi-disciplinary treatment on their survival. Fifty-eight patients with pharyngeal, laryngeal or cervical esophageal cancer underwent free jejunal flap (FJF) reconstruction after cancer resection between 2010 and 2013. All their clinical records were reviewed and analyzed. The success rate of flap transplantation was 91.4% (53/58). The 2-year overall survival rates (OSR) of cervical esophageal cancer and hypopharyngeal cancer patients were 67.5% and 49.3%, respectively, both were significantly better than that of laryngeal cancer. The main causes of death were local recurrence and distant metastases. The group with no short-term complications had a better two-year OSR (59.0%) than the group with short-term complications (46.6%), however, the difference between them was not significant (P=0.103). The 2-year survival rate of the initial treatment group was 65.0%, better than that of the salvage treatment group (49.4%), but the difference was not significant (P=0.051). For the stage III and IV patients, the multi-disciplinary treatment group had a significantly better 2-year OSR (64.7%) than the single or sequential treatment group (37.0%, P=0.016). Free jejunal flap reconstruction is an ideal option for repairing the cervical digestive tract circumferential defects caused by tumor resection with a high success rate and a low mortality. Compared with the single or sequential treatment, multi-disciplinary treatment can significantly improve the survival rate of late-stage hypopharyngeal and cervical esophageal cancer patients.

    Recent literature on chemoradiotherapy for esophageal cancer report the comparable survival results as surgery, and suggest the importance of management for the late adverse effect of chemoradiotherapy. The aim of this study is to investigate the incidence and risk factors of cardiomegaly after chemoradiotherapy using low dose continuous infusion of 5FU/CDDP+5FU for esophageal cancer. Fifty-one patients with stage I-IVA esophageal cancer who were treated by radiotherapy with more than 50 Gy with or without chemotherapy and followed up for more than 6 months were analyzed. Sixteen patients were treated by radiation alone and 35 patients were treated by chemoradiotherapy. A change of CTR (cardio-thoracic ratio) was defined as the difference between CTR in the pre-treatment X-ray film and CTR in the post-treatment X-ray film with maximum cardiac silhouette. A change of CTR by more than 10% was defined as ''significant cardiomegaly''. In this study cardiac area-dose'', which is the sum of the products of cardiac area within every radiation field and its target dose, was calculated in each patient as a radiation parameter. Significant cardiomegaly was noted in 1 patient (6%) in the radiation alone group, in 8 patients (23%) in the chemoradiotherapy group and in 9 patients (18%) in the total population. In cases with more than 0.4 m{sup 2}{center_dot}Gy in cardiac area-dose, CTR elevation was significantly higher than in cases with less than 0.4m{sup 2}{center_dot}Gy. More than moderate pleural effusion was noted in 5 patients (10%). Chronic pericardial effusion and subsequent cardiac tamponade was considered to be one of the contributing factors for pleural effusion, because increases of pleural effusion coincided with CTR elevations in 3 cases. In addition, the fact that no case had right-sided unilateral pleural effusion suggested the direct effect of radiation to the pleura. Significant cardiomegaly was seen in 18% of 51 patients with

    Esophageal cancer is currently the eighth most common cancer worldwide. Improvements in operative techniques and neoadjuvant therapies have led to improved outcomes. Resection of the esophagus carries a high risk of severe complications and has a negative impact on health-related quality of life (QOL). The aim of this study was to assess which patient-reported outcome measures (PROMs) are used to measure QOL after esophagectomy for cancer. A comprehensive search of original articles was conducted investigating QOL after surgery for esophageal carcinoma. Two authors independently selected relevant articles, conducted clinical appraisal, and extracted data (PJ and JS). Out of 5893 articles, 58 studies were included, consisting of 41 prospective and 17 retrospective cohort studies, including a total of 6964 patients. These studies included 11 different PROMs. The existing PROMs could be divided into generic, symptom-specific, and disease-specific questionnaires. The European Organisation for Research and Treatment of Cancer (EORTC) QOL Questionnaire Core 30 (QLQ C-30) along with the EORTC QLQ-OESophagus module OES18 was the most widely used; in 42 and 32 studies, respectively. The EORTC and the Functional Assessment of Cancer Therapy (FACT) questionnaires use an oncological module and an organ-specific module. One validation study was available, which compared the FACT and EORTC, showing moderate to poor correlation between the questionnaires. A great variety of PROMs are being used in the measurement of QOL after surgery for esophageal cancer. A questionnaire with a general module along with a disease-specific module for assessment of QOL of different treatment modalities seem to be the most desirable, such as the EORTC and the FACT with their specific modules (EORTC QLQ-OES18 and FACT-E). Both are developed in different treatment modalities, such as in surgical patients. With regard to reproducibility of current results, the EORTC is recommended. © 2015

    Full Text Available Purpose: Intensity modulated radiotherapy (IMRT for cervical esophageal cancer is challenging. Although IMRT techniques using inverse planning algorithms are facilitating the treatment planning process, the irradiation dose to the normal tissues can be a critical issue. This study was performed to investigate the effect of beam numbers and their directions and local optimization on: (1 dose conformity and homogeneity to the planning target volume (PTV and (2 dose to the organ at risks (OARs.Methods: Four upper esophageal cancer cases were randomly selected for this treatment planning study. Eight IMRT plans were generated for each case with the same dose-volume constraints but with different beam numbers and arrangements. Local optimization using regular structures drawn automatically around the PTV with margins from 0.5-1.5 cm was performed. IMRT plans were evaluated with respect to isodose distributions, dose-volume histograms (DVHs parameters, homogeneity index (HI, and conformity index (CI. The statistical comparison between the types of plans was done using the One Way ANOVA test.Results: The results showed that IMRT using three or five beams was not sufficient to obtain good dose optimization. The seven field plans showed the best coverage for the PTV with tolerable doses for the OARs, and the beam orientation was very critical. Increasing beams (Bs number from 7 to 13 did not show significant differences in the PTV coverage, while the mean lung dose was increased. The PTV coverage were 95.1, 95.1, 98.1, 97.3, 97.3, 97.3, 97.0, and 97.0% for 3Bs, 5Bs, 7Bs, 9Bs, 13Bs, 7Bs(30, 7Bs(60 (beam angles were changed from 0o to 30o and 60o, and 7Bs(R (seven IMRT plans with ring, respectively.

    Many studies have showed that diabetes mellitus (DM) might be a risk factor for certain types of cancers. However, there are still inconsistent results on the effects of DM on the risk of esophageal cancer (EC). The objective of this study is to investigate the association and to quantify the correlation between DM and EC by a meta-analysis. The initial search identified 339 articles. Those publications that did not report the exact number of EC cases were removed. Finally, 13 meaningful studies were extracted from the databases of PubMed, MEDLINE, and Web of Science. All pooled analyses of risk ratios (RRs) and 95% confidence intervals (CIs) were assessed by a random-effect or fixed-effect model. Subgroup analysis was implemented on the basis of the sex or ethnicity. I value was used to assess heterogeneity, and funnel plot analysis was for publication bias. The result showed that there was a positive correlation between type 2 diabetes mellitus (T2DM) and EC risk (RR = 1.28, 95% CI: 1.12-1.47, P < .001). Subgroup analysis based on gender showed that male was an important risk factor for EC (RR = 1.53, 95% CI: 1.44-1.62, P < .001), but female was not (RR = 1.23, 95% CI: 0.41-3.69, P = .71). In addition, subgroup analysis based on ethnicity showed that DM was significantly correlated to EC in North America subjects (RR = 1.39, 95% CI: 1.31-1.47, P < .001), and in Europe subjects (RR = 1.37, 95% CI: 1.02-1.83, P = .04), whereas no correlation was found in Asian subjects (RR = 0.98, 95% CI: 0.50-1.95, P = .96). Furthermore, DM had a correlation to an increased risk of esophageal adenocarcinoma (EAC) (RR = 1.43, 95% CI: 1.35-1.51, P < .001). This meta-analysis indicates that DM is positively correlated to EC. However, the results should be interpreted with caution because of the limitations on potential clinical confounding factors in each study included in this meta-analysis.

    AIM: To explore the effect of six bile salts, including glycocholate (GC), glycochenodeoxycholate (GCDC), glycodeoxycholate (GDC), taurocholate (TC), taurochenodeoxycholate (TCDC), taurodeoxycholate (TDC), and two bile acids including cholic acid (CA) and deoxycholic acid (DCA) on esophageal cancer Eca109 cell line.METHODS: Eca109 cells were exposed to six bile salts, two bile acids and the mixed bile salts at different concentrations for 24-72 h. 3-[4,5-Dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay was used to detect the cell proliferation. Apoptotic morphology was observed by phase-contrast video microscopy and deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL)assay. Sub-G1 DNA fragmentations and early apoptosis cells were assayed by flow cytometry (FCM) with propidium iodide (PI) staining and annexin V-FITC conjugated with PI staining. Apoptosis DNA ladders on agarose were observed. Activation of caspase-3 was assayed by FCM with FITC-conjugated monoclonal rabbit anti-active caspase3 antibody and expressions of Bcl-2 and Bax proteins were examined immunocytochemically in 500 μmol/L-TC-induced apoptosis cells.RESULTS: Five bile salts except for GC, and two bile acids and the mixed bile salts could initiate growth inhibition of Eca109 cells in a dose- and time-dependent manner.TUNEL, FCM, and DNA ladder assays all demonstrated apoptosis induced by bile salts and bile acids at 500 μmol/L,except for GC. Early apoptosis cell percentages in Eca109 cells treated with GCDC, GDC, TC, TCDC, TDC,CA at 500 μmol/L for 12 h, DCA at 500 μmol/L for 6 h,and mixed bile salts at 1 000 μmol/L for 12 h were 7.5%,8.7%, 14.8%, 8.9%, 7.8%, 9.3%, 22.6% and 12.5%,respectively, all were significantly higher than that in control (1.9%). About 22% of the cell population treated with TC at 500 μmol/L for 24 h had detectable active caspase-3, and were higher than that in the control (1%).

    AIM: To detect aneusomic changes with respect to chromosome 11 copy number in esophageal precancers and cancers wherein the generation of cancer-specific phenotypes is believed to be associated with specific chromosomal aneuploidies.METHODS: We performed fluorescence in situ hybridization (FISH) on esophageal tissue paraffin sections to analyze changes in chromosome 11 copy number using apotome-generated images by optical sectioning microscopy. Sections were prepared from esophageal tumor tissue, tissues showing preneoplastic changes and histologically normal tissues (control)obtained from patients referred to the clinic for endoscopic evaluation.RESULTS: Our results demonstrated that aneusomy was seen in all the cancers and preneoplastic tissues, while none of the controls showed aneusomic cells. There was no increase in aneusomy from precancers to cancers.CONCLUSION: Our results suggest that evaluation of chromosome 11 aneusomy in esophageal tissue using FISH with an appropriate signal capture-analysis system, can be used as an ancillary molecular marker predictive of early neoplastic changes. Future studies can be directed towards the genes on chromosome 11,which may play a role in the neoplastic transformation of esophageal precancerous lesions to cancers.

    A combination of chemotherapy and radiotherapy (chemoradiation therapy; CRT) has recently been developed to improve the survival of esophageal cancer patients. However, the optimal choice of chemotherapeutic agents and their doses, as well as chemotherapy and radiotherapy regimens, remain unclear. Based on recent advances in knowledge on the radiosensitizing and biochemical modulation effects of chemotherapeutic agents, we have recently developed concurrent CRT which consisted of continuous 5-fluorouracil (5FU) administration (600 mg/m{sup 2}/day, days 1-5) combined with a low dose of daily cisplatin administration (10 mg/m{sup 2}/day, days 1-5, and 5 or 10 mg/m{sup 2}/day, days 8-12 and 15-19) before each fraction of radiation (2 Gy each). To evaluate the efficacy and safety of our concurrent CRT, 10 esophageal cancer patients received one or one and a half courses of the CRT. All patients tolerated and completed a full course of the CRT. The effectiveness of the CRT on the primary tumor included pathologically or endoscopically complete responses in three patients (30%), partial response in five (50%), no response in two (20%) and tumoral downstaging (T-classification) in five (50%). Grade 2 and Grade 3 toxicity, seen in six patients, did not affect surgical operation. No patients showed CRT-related deaths. Eight patients (80%) underwent resection with no operative mortality. Of these, two patients (25%) showed pathologically or endoscopically complete responses, and four (50%) showed partial response. Three patients died of cancer after resection. The two inoperable patients showed a pathologically complete response and p
