    Background: We reviewed clinical results of chemoradiotherapy (CRT) in the treatment of patients with advanced esophageal cancer with fistulae that developed before or during CRT. Methods and Materials: The study group included 16 patients with fistulous esophageal cancer treated by means of CRT between 1999 and 2006. Nine patients had fistulae before CRT, whereas 7 developed fistulae during CRT. The group included 12 men and four women with a median age of 55 years (range, 37-77 years). There were 9 patients with Stage III disease and 7 with Stage IV disease. All tumors were squamous cell carcinomas. Two courses of concurrent chemotherapy were combined with radiation therapy; 60 Gy/30 fractions/7 weeks (1-week split). For 15 patients, low-dose protracted chemotherapy with 5-fluorouracil (250-300 mg/m{sup 2} x 14 days) and cisplatin (7 mg/m{sup 2} x 10 days) was administered, whereas full-dose cisplatin and 5-fluorouracil were administered to the remaining patient. Results: The planned dose of 60 Gy was delivered to 11 patients (69%), whereas radiation therapy was terminated early in 5 patients (40-58 Gy) because of acute toxicities, including two treatment-related deaths. Disappearance of fistulae was noted during or after CRT in 7 patients (44%). All three esophagomediastinal fistulae were closed, but only four of 13 esophagorespiratory fistulae were closed by CRT. For patients with Stage III, 1- and 2-year survival rates were 33% and 22%, respectively. Median survival time was 8.5 months. Conclusion: Despite significant toxicity, concurrent CRT appears effective at closing esophageal malignant fistulae.

    Rigid esophagoscopy (RE) was once an essential part of the evaluation of patients with head and neck squamous cell carcinoma (HNSCC) due to the high likelihood of identifying a synchronous malignant neoplasm in the esophagus. Given recent advances in imaging and endoscopic techniques and changes in the incidence of esophageal cancer, the current role for RE in HNSCC staging is unclear. To analyze the current role of RE in evaluating patients with HNSCC, and to determine the incidence of synchronous esophageal malignant neoplasms in patients with HNSCC. In this retrospective study performed at an academic tertiary care center, 582 patients were studied who had undergone RE for HNSCC staging from July 1, 2004, through October 31, 2012. To assess the incidence of synchronous esophageal malignant neoplasms, a literature review was performed, and the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) data set was queried. The primary outcome measure was the incidence of synchronous esophageal malignant neoplasms, as measured by retrospective review at our institution, SEER data set analysis, and literature review. Secondary outcome measures were RE complications and nonmalignant findings during RE. A total of 601 staging REs were performed in 582 patients. The mean age was 60.2 years and 454 (78.0%) were men. There were 9 complications (1.5%), including 1 esophageal perforation (0.2%). Rigid esophagoscopy was aborted in 50 cases. Of the 551 completed REs, no abnormal findings were noted in 523 patients (94.9%), and nonmalignant pathologic findings were identified in 28 patients (5.1%). No synchronous primary esophageal carcinomas were detected. The incidence of synchronous esophageal malignant neoplasms found on screening endoscopy based on literature review and on SEER data set analysis was very low and has decreased from 1980 to 2010 in North America. The incidence reported in South America and Asia was relatively high. Rigid esophagoscopy

    Esophageal cancer is mainly found in Asia and east Africa and is one of the deadliest cancers in the world. However, it has not garnered much attention in the Western world due to its low incidence rate. An increasing amount of data indicate that esophageal cancer, particularly esophageal adenocarcinoma, has been rising by 6-fold annually and is now becoming the fastest growing cancer in the United States. This rise has been associated with the increase of the obese population, as abdominal fat puts extra pressure on the stomach and causes gastroesophageal reflux disease (GERD). Long standing GERD can induce esophagitis and metaplasia and, ultimately, leads to adenocarcinoma. Acid suppression has been the main strategy to treat GERD; however, it has not been proven to control esophageal malignancy effectively. In fact, its side effects have triggered multiple warnings from regulatory agencies. The high mortality and fast growth of esophageal cancer demand more vigorous efforts to look into its deeper mechanisms and come up with better therapeutic options. PMID:23236223

    We investigated the association between esophageal cancer and cachexia-anorexia syndrome (CAS) of the alimentary tract and leptin, an adipocytokine crucial for body weight regulation, a modulator of inflammatory/immune response, implication of which in cancer and CAS development remains debatable. Circulating leptin was measured in 135 esophageal cancer patients (51 non-cachectic and 84 cachectic) and 83 controls (63 non-cachectic and 20 cachectic) and referred to cancer stage, CAS, and inflammatory and nutritional indices. Leptin was down-regulated in cancer patients and cachectic controls as compared to non-cachectic controls, with more pronounced hypoleptinemia in advanced cancers. Leptin correlated directly with BMI, TNF-alpha, albumin, and hemoglobin and indirectly with IL-6, IL-8, and hsCRP. The correlations, except for hsCRP, were more pronounced in females. BMI alone (females) and BMI and hsCRP (males) were independent predictors of leptin explaining over 60% of its variability. Following adjustment for BMI and gender, cancer-related CAS but not cancer itself negatively affected leptin. Leptin and BMI were independently associated with cancer-related and non-malignant CAS with diagnostic accuracy of 93% in identifying subjects with CAS. Pro-inflammatory, angiogenic and mitogenic properties of leptin do not seem to be important for esophageal cancer development but hypoleptinemia, independently from co-occurring reduction of adiposity, appears to be strongly associated with esophageal cancer-related CAS and non-malignant CAS of the alimentary tract.

    The high incidence of esophageal squamous cell carcinoma has been reported in selected ethnic populations including North of Iran. Low survival rate of esophageal carcinoma is partially due to the presence of stem-like cancer cells with chemotherapy resistance. In the current study, we aimed to determine the effects of auraptene, an interesting dietary coumarin with various biological activities, on malignant properties of stem-like esophageal squamous cell carcinoma, in terms of sensitivity to anticancer drugs and expression of specific markers. To do so, the half maximal inhibitory concentration values of auraptene, cisplatin, paclitaxel, and 5-fluorouracil were determined on esophageal carcinoma cells (KYSE30 cell line). After administrating combinatorial treatments, including nontoxic concentrations of auraptene + cisplatin, paclitaxel, or 5-fluorouracil, sensitivity of cells to chemical drugs and also induced apoptosis were assessed. In addition, quantitative real-time polymerase chain reaction was used to study changes in the expression of tumor suppressor proteins 53 and 21 ( P53 and P21), cluster of differentiation 44 ( CD44), and B cell-specific Moloney murine leukemia virus integration site 1 ( BMI-1) upon treatments. Results of thiazolyl blue assay revealed that auraptene significantly ( P < .05) increased toxicity of cisplatin, paclitaxel, and 5-fluorouracil in KYSE30 cells, specifically 72 hours after treatment. Conducting an apoptosis assay using flow cytometry also confirmed the synergic effects of auraptene. Results of quantitative real-time polymerase chain reaction revealed significant ( P < .05) upregulation of P53 and P21 upon combinatorial treatments and also downregulation of CD44 and BMI-1 after auraptene administration. Current study provided evidence, for the first time, that auraptene attenuates the properties of esophageal stem-like cancer cells through enhancing sensitivity to chemical agents and reducing the expression of CD44 and BMI-1

    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.

    The abnormal function of O(6)-methylguanine-DNA methyltransferase (MGMT) is reported to be associated with the occurrence of various tumors and malignant tumor progression. However, little evidence is available to describe its role in esophageal carcinogenesis. To address this issue, we constructed a stable MGMT-silenced esophageal cancer cell line by RNA interference, and exposed the cells to N-methyl-N-nitro-N-nitrosoguanidine (MNNG) to investigate the role that MGMT plays in toxicity. During this time, we also observed the malignant behavior of cells in vitro and in vivo. In addition, two-dimensional electrophoresis and mass spectrometry were used to detect and confirm the proteins that were differentially expressed in the MGMT-deficient and MGMT-proficient cells, which might be responsible for the malignant alteration of cells. Results showed that the IC(50) of MGMT-deficient and MGMT-proficient cells exposed to MNNG was 30 μM and 65 μM, respectively, and MGMT-deficient cells had more aggressive motility and invasive abilities compared with MGMT-proficient cells. Nineteen differentially expressed proteins were detected between the MGMT-deficient and MGMT-proficient cells, 14 of which were identified, including the membrane-cytoskeleton linker protein, Ezrin, which was confirmed by both mass spectrometry and western blot analysis. The correlation between MGMT, Ezrin expression, and the malignant behavior of one normal epithelial esophageal cell line and seven esophageal cancer lines is discussed. In conclusion, loss of MGMT expression leads EC109 esophageal cancer cells to have increased malignant behavior, which may correlate with its high Ezrin protein expression.

    In humans, esophageal cancer-related gene 4 (ECRG4) is encoded by four exons in the c2orf40 locus of chromosome 2. Translation of ECRG4 messenger ribonucleic acid produces a 148 amino acid-secreted 17 KDa protein that is then processed to 14, ten, eight, six, four, and two KDa peptides, depending on the cell in which the gene is expressed. As hypermethylation at the c2orf40 locus inhibits ECRG4 gene expression in many epithelial cancers, several investigators have speculated that ECRG4 is a candidate tumor suppressor. Indeed, overexpression of ECRG4 inhibits cell proliferation in vitro, but it also has a wide range of effects in vivo beyond its antitumor activity. ECRG4 overexpression affects apoptosis, senescence, cell migration, inflammation, injury, and infection responsiveness. ECRG4 activities also depend on its cellular localization, secretion, and post-translational processing. These cytokine/chemokine-like characteristics argue that ECRG4 is not a traditional candidate tumor suppressor gene, as originally predicted by its downregulation in cancer. We review how insights into the regulation of ECRG4 gene expression, knowledge of its primary structure, and the study of its emerging physiological functions come together to support a much more complex role for ECRG4 at the interface of inflammation, infection, and malignancy.

    Lysine-specific demethylase-1 (LSD1) removes the methyl groups from mono- and di-methylated lysine 4 of histone H3. Previous studies have linked LSD1 to malignancy in several human tumors, and LSD1 is considered to epigenetically regulate the energy metabolism genes in adipocytes and hepatocellular carcinoma. This study investigates the function of LSD1 in the invasive activity and the metabolism of esophageal cancer cells. We investigated whether LSD1 immunohistochemical expression levels are related to clinical and pathological features, including the maximum standard uptake value in fluorodeoxyglucose positron emission tomography assay. The influence of LSD1 on cell proliferation, invasion and glucose uptake was evaluated in vitro by using specific small interfering RNA for LSD1, and an LSD1 inhibitor. We also evaluated two major energy pathways (glycolytic pathway and mitochondrial respiration) by measuring the extracellular acidification rate (ECAR) and the oxygen consumption rate (OCR) with an extracellular flux analyzer. High LSD1 immunohistochemical expression was significantly associated with high tumor stage, lymphovascular invasion, poor prognosis, and high maximum standard uptake value in esophageal cancer patients. In the in vitro analysis, LSD1 knockdown significantly suppressed the invasive activity and glucose uptake of cancerous cells, reduced their ECAR and increased their OCR and OCR/ECAR. LSD1 may contribute to malignant behavior by regulating the invasive activity and metabolism, activating the glycolytic pathway and inhibiting the mitochondrial respiration of esophageal cancer cells. The results support LSD1 as a potential therapeutic target. © 2015 UICC.

    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.

    A case of dermatomyositis and esophageal cancer is described. A 58-year-old male recently diagnosed with esophageal cancer was admitted to the hospital with complaints of progressive dysphagia, generalized muscle weakness and skin rash. The weakness started symmetrically in the proximal limb muscles. He also developed a characteristic skin rash on the eyelids, the upper chest and around the nails that was thought to be most indicative of dermatomyositis. Creatine kinase, aspartate aminotransferase and aldolase were elevated. A muscle biopsy showed various degrees of degeneration with perivascular interstitial infiltration of lymphoplasma cells, a finding consistent with "dermatomyositis." The patient was started on corticosteroids and within two weeks, his muscle strength was found to be markedly improved and the rash almost disappeared. Dysphagia can be the presenting symptom of both dermatomyositis and esophageal cancer. In the setting of an underlying malignancy, these symptoms can be misleading and one can miss the diagnosis of dermatomyositis. However, recognition of the characteristic skin rash may provide a clue to the diagnosis. Another aspect of our case that is worth acknowledgment is the quick response to treatment with corticosteroids.

    Radiotherapy and surgery have both played prominent roles in the treatment of esophageal cancer since the beginning of the 20th century. Although the use of radiotherapy alone to treat esophageal cancer has a long history, it has not demonstrated improved outcomes compared with surgery alone. The disappointing rates of survival and local control associated with single-modality therapy and the need for effective nonsurgical management led to the development of definitive chemoradiotherapy paradigms for esophageal cancer. Adding cytotoxic chemotherapy to radiotherapy for additive or synergistic effect was described as early as 1968, and over time, treatment has shifted from single-modality therapy toward combined-modality therapy using chemotherapy and radiotherapy. This approach eventually demonstrated superior outcomes in patients with esophageal cancer when compared to radiotherapy alone. Maximum benefit of this therapy depends on the appropriate addition of surgery and the optimization of radiosensitizing chemotherapy. A burgeoning area of research has focused on improving definitive chemoradiotherapy strategies through the incorporation of newer chemotherapeutic agents and targeted biologic agents. An overview of the history of chemoradiotherapy in the treatment of esophageal cancer is presented, as well as a discussion of ongoing studies and future areas of promising research. PMID:19461907

    It remains controversial whether chemotherapy and/or radiotherapy are/is contraindicated for esophageal carcinoma patients with malignant fistulae. In some case reports, closure of fistulae by chemotherapy or radiotherapy has been reported. The current study investigated chemoradiotherapy for these patients using various primary treatments to manage the pulmonary complications. The aim of this study was to evaluate the efficacy and feasibility of chemoradiotherapy for patients with locally advanced esophageal carcinoma with malignant fistulae. Patients with endoscopically or radiologically confirmed fistulae were treated with concomitant chemoradiotherapy. Closure of fistulae was assessed by esophagography or endoscopy. Oral food intake also was assessed before and after treatment. Of 202 esophageal carcinoma patients treated at National Cancer Center Hospital East between July 1992 and May 1998, 24 patients (11.9%) developed malignant fistulae. Twelve patients developed fistulae before treatment and the remaining patients developed fistulae during treatment. Closure of the fistulae after chemoradiotherapy was observed in 17 of these patients (70.8%), and 16 of these 17 patients (94.1%) had oral alimentation restored after successful treatment. The median survival time from the diagnosis of the fistula for all patients with fistulae was 198 days; in the patients whose fistulae were present before chemoradiotherapy, the median survival time was 238 days. These results suggest that the presence of malignant fistulae does not contraindicate chemoradiotherapy. Once the inflammation due to the fistula has been controlled, chemoradiotherapy should be utilized because it may provide the best chance for survival and palliation of severe dysphagia.

    Esophageal cancer is often diagnosed at an advanced stage, with many patients found to have locoregional or metastatic disease at time of diagnosis. Because of this, cure may be unlikely, leading treatment efforts to focus more on symptom palliation and improving patient quality of life. The majority of patients with advanced disease suffer from some degree of dysphagia. Palliative efforts are therefore directed at relieving dysphagia, allowing patients to manage their oropharyngeal secretions, reduce aspiration risk, and maintain caloric intake orally. A variety of endoscopic treatment modalities have been utilized with these objectives in mind, with options determined by the location and size of the tumor, as well as the patient's expected prognosis. In this article, we review the use of endoscopically-placed stents for palliation in patients with advanced esophageal cancer. We discuss the history of stent use in such cases, as well as more recent developments in stent technology. We give an overview of some of the more commonly used stents in practice, discuss the technique of insertion, and survey the short- and long-term outcomes of stent placement.

Department of Pathology, Sana'a University, Sana'a, Yemen, from January 2005 to December 2011. Three hundred twenty five cases of EC were included for review. The diagnoses were made on hematoxylin and eosin stained sections and the cases were categorized into Squamous Cell Carcinoma (SCC) and adenocarcinoma (ADC). Out of the 325 EC cases, 163 (50%) were SCC (females 67%, males 33%) and 158 (49%) were ADC (females 30%, males 70%). The rest of the cases were 2 adenosquamous carcinoma and 2 non-Hodgkin's lymphoma. The mean age, for SCC was 60 years while the mean age for ADC was 65 years. The peak incidence for SCC was found in the age groups of fifth and sixth decades for females and in fifth and seventh decades for males. The maximum number of patients with ADC was seen in sixth and seventh decades for both gender. Well-differentiated histological grading accounted for 247 (77%) for both genders and types. The moderately differentiated and poorly differentiated accounted, for 17% and 6% respectively. The EC in Yemen had a predominance of SCC in female patients and predominance of ADC in male patients which was usually of a well-differentiated grade.

    Synopsis This articles reviews the environmental risk factors and predisposing conditions for the two main histological types of esophageal cancer, esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EA). Tobacco smoking, excessive alcohol consumption, drinking maté, low intake of fresh fruits and vegetables, achalasia, and low socioeconomic status increase the risk of ESCC. Results of investigations on several other potential risk factors, including opium consumption, intake of hot drinks, eating pickled vegetables, poor oral health, and exposure to human papillomavirus, polycyclic aromatic hydrocarbons, N-nitroso compounds, acetaldehyde, and fumonisins are also discussed. Gastroesophageal reflux, obesity, tobacco smoking, hiatal hernia, achalasia, and probably absence of H. pylori in the stomach increase the risk of EA. Results of studies investigating other factors, including low intake of fresh fruits and vegetables, consumption of carbonated soft drink, use of H2 blockers, non-steroidal anti-inflammatory drugs, and drugs that relax the lower esophageal sphincter are also discussed.

    Esophageal cancer represents one of the most aggressive digestive tumors, with a survival rate at 5 years of only 10%. Globally, during the last three decades, there has been an increasing incidence of the esophageal cancer, approx. 400,000 new esophageal cancers being currently diagnosed annually. This represents the eighth leading cause of cancer incidence and the sixth leading cause of cancer death overall. Taking into account the population’s global aging and thus, the increase in the number of patients who will not bear surgery, PCT and radiation, or the fact that they do not want it especially because of deficiencies and associated pathology, the endoscopic ablative techniques with palliation purposes represent the alternative. If we refer to the Western Europe countries and North America, we notice an increase of esophageal adenocarcinoma rate versus squamous cancer. As for the Asian region, referring in particular to China and Japan, 9 out of 10 esophageal cancers are squamous cell carcinomas. For at least half of the patients with EC (esophageal cancer) there is no hope of healing because of the advanced regional malignant invasion (T3-4, N+, M+) with no chemo and radiotherapy response, poor preoperative patients’ conditions or systemic metastasis. The low life expectancy does not justify the risky medical procedures, the goal of the therapy consisting in the improvement of the quality of life by eliminating dysphagia (reestablishing oral feeding) which represents the most common complication of EC, the respiratory tract complication caused by eso-tracheal fistulas or by eliminating chest pain. To treat dysphagia, which is the main target of palliation, combined methods like endoscopic, chemo and radio-therapy, can be used, each one with indications, benefits and risks.

    Background Esophageal cancer (EC) is the eighth most prevalent malignant tumor and the sixth leading cause of cancer mortality throughout the world. Despite the technical developments in diagnosis and treatment, the 5-year survival rate is still low. The etiology of EC remains poorly understood; multiple risk factors may be involved and account for the great variation in EC incidence in different geographic regions. Summary Infection with carcinogenetic pathogens has been proposed as a risk factor for EC. This review explores the recent studies on the association of human papillomavirus (HPV), Epstein-Barr virus (EBV), Helicobacter pylori and esophageal bacterial biota with EC. Key Message Among the above-mentioned pathogens, HPV most likely contributes to esophageal squamous cell carcinoma (ESCC) in high-risk populations. New techniques are being applied to studies on the role of infection in EC, which will inevitably bring novel ideas to the field in the near future. Practical Implications Multiple meta-analyses support the finding of a higher HPV detection rate in regions associated with high risk for ESCC compared to low-risk areas. A potential role of HPV in the rise of esophageal adenocarcinoma (EAC) was proposed recently. However, further studies are required before a firm conclusion can be drawn. Less work has been done in studying the association between EBV and ESCC, and the results are quite controversial. H. pylori infection is found to be inversely related to EC, which is probably due to the reduced incidence of gastroesophageal reflux disease. Analysis of the esophageal bacterial biota revealed distinct clusters of bacteria in normal and diseased esophagi. A type II microbiome rich in Gram-negative bacteria potentially contributes to EAC by inducing chronic inflammation. Novel findings from such studies as these may benefit public health by justifying anti-infection measures to prevent EC. PMID:26674173

    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.

    Esophageal cancer (EC) and gastric cancer (GC) constitute a major cause of cancer deaths worldwide. Recent improvements in both surgical techniques and adjuvant/neoadjuvant chemotherapy, radiotherapy or both have increased the survival of patients with loco-regional disease. However, most patients with GC or EC have advanced disease either at diagnosis or during the follow-up, and despite recent advances, these patients still do poorly. Understanding of the molecular pathways that characterize cell growth, cell cycle, apoptosis, angiogenesis and invasion has provided novel targets in cancer therapy. In this review we describe the current status of targeted therapies in the treatment of EC and GC, including EGFR inhibitors, antiangiogenic agents, cell cycle inhibitors, apoptosis promoters and matrix metalloproteinases inhibitors. The emerging data from the clinical development of these compounds has provided novel opportunities in the treatment of EC and GC that will probably translate into clinical benefit for patients with these common malignancies.

    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. PMID:28210168

    During the period included between January 1970 and December 1990, we studied 242 patients with manometric and radiological diagnosis of esophageal achalasia. Eight of these patients (3.3%) developed during the evolution of their disease an esophageal carcinoma. Eight cases showed histologic type of epidermoid carcinoma: 3 differentiated, 3 semi-differentiated and 2 anaplastic. Therapy for achalasia was: one patient, Heller myotomy, 4 patients, dilatations with bougies in numerous opportunities, and the other two patients receive no treatment for achalasia. Two patients reported tracheobronchial fistulas as complication of carcinoma. Treatment received for carcinoma included: three patients, radiotherapy (4000 rads); one patient, chemotherapy; one patient, chemotherapy and radiotherapy, one resection surgery and two patients feeding gastrostomy. All of the eight patients died within the year of diagnosis of epidermoid carcinoma.

    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. PMID:27956773

    2010-01-01

    AIM: To evaluate the efficacy of self expandable metallic stents (SEMS) in patients with malignant esophageal obstruction and fistulas. METHODS: SEMS were implanted in the presence of fluoroscopic guidance in patients suffering from advanced and non-resectable esophageal, cardiac and invasive lung cancer between 2002 and 2009. All procedures were performed under conscious sedation. All patients had esophagus obstruction and/or fistula. In all patients who required reintervention, recurrence of dysphagia, hemorrhage, and fistula formation were indications for further endoscopy. Patients’ files were scanned retrospectively and the obtained data were analyzed using SPSS 13.0 for Windows. The χ2 test was used for categorical data and was analysis of variance for non-categorical data. Patients’ long-term survival was assessed using the Kaplan-Meier method. RESULTS: Stents were successfully implanted in 90 patients using fluoroscopic guidance. Reasons for stent implantation in these patients were esophageal stricture (77/90, 85.5%), external pressure (8/90, 8.8%) and tracheo-esophageal fistula (5/90, 5.5%). Dysphagia scores (mean ± SD) were 3.37 ± 0.52 before and 0.90 ± 0.43 after stent implantation (P = 0.002). Intermittent, non-massive hemorrhage due to the erosion caused by the distal end of the stent in the stomach occurred in only one patient who received implementation at cardio-esophageal junction. Mean survival following stenting was 134.14 d (95% confidence interval: 94.06-174.21). CONCLUSION: SEMS placement is safe and effective in the palliation of dysphagia in selected patients with malignant esophageal strictures. PMID:21128325

    Routine screening for esophageal cancer in head and neck cancer patients in Thailand is controversial, because of concerns regarding the screening methods and cost effectiveness. Since Lugol dye chromoendoscopy is an effective technique for early detection of squamous cell carcinoma of the esophagus, the objectives of the present study are to evaluate the synchronous esophageal cancer in head and neck cancer patients and the effectiveness of Lugol dye chromoendoscopy for routine screening. All diagnosed patients with head and neck cancer between September 1, 2009 and June 30, 2011 were enrolled into the study. Both conventional esophagoscopy and Lugol dye chromoendoscopy were done. The incidence of esophageal cancer was calculated. A diagnostic statistical analysis was done to compare the diagnostic properties between conventional esophagoscopy and Lugol dye chromoendoscopy. Univariate and multivariate logistic regression analyses were used to find significant factors associated with esophageal cancer in this study. Eighty-nine head and neck cancer patients were enrolled in this study. The incidence of esophageal cancer in head and neck cancer patients was 12.4% (11/89). Conventional esophagoscopy found a highly suspicious malignant lesion in only six patients, while the Lugol dye chromoendoscopy detected all 11 esophageal cancers. The sensitivity and specificity for conventional esophagoscopy were 54.5% and 100%, respectively, andfor Lugol dye chromoendoscopy were 100% and 70.5%, respectively. The three significant factors that increased the likelihood of synchronous esophageal cancer from univariate analysis were age less than 50 years, presence of dysphagia, and an unstained Lugol dye area ≥10 mm. Howeve, these factors were not statistically significant by multivariate analysis. Lugol dye chromoendoscopy is a promising tool to enhance the diagnosis of esophageal cancer among head and neck cancer patients.

    Patients with resectable esophageal cancer often require placement of a surgical jejunostomy tube prior to receiving chemoradiation so as to maintain adequate nutrition due to their inability to swallow and eat. This study reports a single institutional experience with the Polyflex self-expanding silicone stent (Riisch; Kernen. Germany) in patients with malignant stenosis receiving chemoradiation prior to esophagectomy. This was a retrospective, nonrandomized study of 6 patients who underwent Polyflex esophageal stent placement across a malignant stricture prior to receiving neoadjuvant chemoradiation. The study assessed procedural success, restoration of oral nutrition, migration, and removal of the Polyflex stent. The outcomes measured were the efficacy of treatment, stent-related complications, and changes in the nutritional status of the patient after stent placement. Stent placement was successful in 5 of 6 patients (83%). Restoration of oral nutrition after stent placement occurred in 5 of 5 patients (100%). Migration of the stent into the stomach occurred in 3 patients (60%) without occurrence of gastric outlet obstruction; there was no proximal migration. Stents were successfully removed endoscopically or at the time of esophagectomy. This early experience suggests that the removable silicone Polyflex stent is an effective alternative to a surgical jejunostomy tube for the management of malignant esophageal stenosis in patients for whom neoadjuvant chemoradiation is planned prior to esophagectomy.

    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 cancer (EC) is the fourth leading cause of cancer death in China. Despite a lot of advances in diagnosis and therapy, the survival rate of patients with EC is low. There is urgent need for a variety of methods and techniques to improve the survival time and alleviate the lesions of EC. Nowadays, alternative and less invasive approaches to the treatment of ECs are being identified. Here, we review several main interventional methods at different stages of EC, including endoscopic resection, stent placement, arterial infusion, photodynamic therapy, and radiofrequency ablation. This review will focus on the indications, methods, clinical outcomes, and complications of these methods, which may help guide the way forward. PMID:27904858

    This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE), endorsed by the European Society for Radiotherapy and Oncology (ESTRO), the European Society of Digestive Endoscopy (ESDO), and the European Society for Clinical Nutrition and Metabolism (ESPEN). The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was adopted to define the strength of recommendations and the quality of evidence. Main recommendations for malignant disease 1 ESGE recommends placement of partially or fully covered self-expandable metal stents (SEMSs) for palliative treatment of malignant dysphagia over laser therapy, photodynamic therapy, and esophageal bypass (strong recommendation, high quality evidence). 2 For patients with longer life expectancy, ESGE recommends brachytherapy as a valid alternative or in addition to stenting in esophageal cancer patients with malignant dysphagia. Brachytherapy may provide a survival advantage and possibly a better quality of life compared to SEMS placement alone. (Strong recommendation, high quality evidence.) 3 ESGE recommends esophageal SEMS placement as the preferred treatment for sealing malignant tracheoesophageal or bronchoesophageal fistula (strong recommendation, low quality evidence). 4 ESGE does not recommend the use of concurrent external radiotherapy and esophageal stent treatment. SEMS placement is also not recommended as a bridge to surgery or prior to preoperative chemoradiotherapy. It is associated with a high incidence of adverse events and alternative satisfactory options such as placement of a feeding tube are available. (Strong recommendation, low quality evidence.) Main recommendations for benign disease 1 ESGE recommends against the use of self-expandable stents (SEMSs) as first-line therapy for the management of benign esophageal strictures because of the potential for adverse events, the availability of alternative therapies, and costs (strong

    Over half of patients diagnosed with esophageal cancer are unsuitable for curative resection. A significant proportion of these patients will subsequently require palliative stenting to alleviate dysphagia. There is growing consensus in the literature that the deployment of a Self-Expanding Metal Stent is the optimum stenting strategy; however, it remains unclear whether covered or uncovered metal stents are more cost-effective. In order to determine which type of prosthesis is more cost-effective, we compared the different stenting strategies in terms of 1-year stent-related mortality, health-related quality of life, and cost. A decision analytical model was constructed to compare the 1-year stent-related mortality, health-related quality of life, and cost between covered and uncovered stents. Probabilistic sensitivity analysis was performed to quantify the uncertainty associated with our results. Value of Information analysis was performed to assess the value of further research. In order to fully characterize the uncertainty associated with this decision, plastic stents were included in our analysis. Stent-related mortality was slightly lower following covered stent deployment compared with uncovered stent deployment (1.00% vs. 1.26%). Covered stents were more effective by 0.0013 Quality-Adjusted Life Years (Standard Deviation [SD] 0.0013 Quality-Adjusted Life Years). They were also less expensive by $729.58 (SD $390.63). Probabilistic sensitivity analysis suggested that these results were not sensitive to model parameter uncertainty. Plastic stents deployment was $2832.64 (SD $1182.72) more expensive than uncovered metal stent deployment. Value of Information analysis suggests that the maximum value of further research in the UK is $61,124.30. The results of this study represent strong evidence for the cost-effectiveness of covered compared with uncovered self-expanding metal stents for the palliation of patients with malignant dysphagia.

    The management of esophageal and gastric cancer is complex and involves multiple specialists in an effort to optimize patient outcomes. Utilizing a multidisciplinary team approach starting from the initial staging evaluation ensures that all members are in agreement with the plan of care. Treatment selection for esophageal and gastric cancer often involves a combination of chemotherapy, radiation, surgery, and palliative interventions (endoscopic and surgical), and direct communication between specialists in these fields is needed to ensure appropriate clinical decision making. At the University of Colorado, the Esophageal and Gastric Multidisciplinary Clinic was created to bring together all experts involved in treating these diseases at a weekly conference in order to provide patients with coordinated, individualized, and patient-centered care. This review details the essential elements and benefits of building a multidisciplinary program focused on treating esophageal and gastric cancer patients. PMID:27217796

    2016-01-01

    Esophageal cancer is a deadly disease, ranking sixth among all cancers in mortality. Despite incremental advances in diagnostics and therapeutics, esophageal cancer still carries a poor prognosis, and thus there remains a need to elucidate the molecular mechanisms underlying this disease. There is accumulating evidence that a comprehensive understanding of the molecular composition of esophageal cancer requires attention to not only tumor cells but also the tumor microenvironment, which contains diverse cell populations, signaling factors, and structural molecules that interact with tumor cells and support all stages of tumorigenesis. In esophageal cancer, environmental exposures can trigger chronic inflammation, which leads to constitutive activation of pro-inflammatory signaling pathways that promote survival and proliferation. Anti-tumor immunity is attenuated by cell populations such as myeloid-derived suppressor cells (MDSCs) and regulatory T cells (Tregs), as well as immune checkpoints like programmed death-1 (PD-1). Other immune cells such as tumor-associated macrophages can have other pro-tumorigenic functions, including the induction of angiogenesis and tumor cell invasion. Cancer-associated fibroblasts secrete growth factors and alter the extracellular matrix (ECM) to create a tumor niche and enhance tumor cell migration and metastasis. Further study of how these TME components relate to the different stages of tumor progression in each esophageal cancer subtype will lead to development of novel and specific TME-targeting therapeutic strategies, which offer considerable potential especially in the setting of combination therapy.

    Background: Chemokine receptors have been shown to play an important role in the development and metastatic spread of various malignancies. In this study, the gene expression profile of some key chemokine receptors involved in metastasis has been investigated in esophageal and breast cancer cell lines. Methods: In a descriptive study, gene expression profile of CCR1, CCR6, CCR7, CCR9, CXCR1, and CXCR4 in human esophageal cancer cell line (KYSE-30) and human breast cancer cell line (MCF7) were analyzed using real-time PCR and their results were compared accordingly. Results: We demonstrated for the first time the expression of CCR1, CCR6, CCR7, CCR9, CXCR1, and CXCR4 at transcriptional level in human esophageal cancer cell line. The expression of CCR1, CCR7 and CXCR4 were lower in esophageal compared with breast cancer cells, although without significant difference. CCR9 was highly expressed in esophageal cancer cells as compared to the breast cancer cells (P < 0.05). Similarly, the expression of CCR6 and CXCR1 were higher, although without significant difference. Conclusion: Esophageal cancer cells like breast cancer express some key chemokine receptors involved in metastasis. Targeting of proposed receptors in esophageal cancer may be a novel strategy for prevention of cancer metastasis. PMID:26576348

    Esophageal cancer (EC) is one of the most common malignancies in low- and medium-income countries and represents a disease of public health importance because of its poor prognosis and high mortality rate in these regions. The striking variation in the prevalence of EC among different ethnic groups suggests a significant contribution of population-specific environmental and dietary factors to susceptibility to the disease. Although individuals within a demarcated geographical area are exposed to the same environment and share similar dietary habits, not all of them will develop the disease; thus genetic susceptibility to environmental risk factors may play a key role in the development of EC. A wide range of xenobiotic-metabolizing enzymes are responsible for the metabolism of carcinogens introduced via the diet or inhaled from the environment. Such dietary or environmental carcinogens can bind to DNA, resulting in mutations that may lead to carcinogenesis. Genes involved in the biosynthesis of these enzymes are all subject to genetic polymorphisms that can lead to altered expression or activity of the encoded proteins. Genetic polymorphisms may, therefore, act as molecular biomarkers that can provide important predictive information about carcinogenesis. The aim of this review is to discuss our current knowledge on the genetic risk factors associated with the development of EC in different populations; it addresses mainly the topics of genetic polymorphisms, gene-environment interactions, and carcinogenesis. We have reviewed the published data on genetic polymorphisms of enzymes involved in the metabolism of xenobiotics and discuss some of the potential gene-environment interactions underlying esophageal carcinogenesis. The main enzymes discussed in this review are the glutathione S-transferases (GSTs), N-acetyltransferases (NATs), cytochrome P450s (CYPs), sulfotransferases (SULTs), UDP-glucuronosyltransferases (UGTs), and epoxide hydrolases (EHs), all of which

Patients with malignant esophageal cancer were randomly assigned to receive a conventional stent (group A) or an iodine-eluting stent (group B). Following implantation, the relief from dysphagia, survival time, routine blood tests, thyroid function examination and complications were compared in the two groups. Groups A and B consisted of 36 and 31 patients, respectively. The mean value that the dysphagia score decreased by was significantly lower in group A (0.83) compared with group B (1.65). The median survival time was longer in group B compared with group A (P=0.0022). No significant differences were observed in the severe complications between the two groups (P=0.084). The iodine-eluting esophageal stent is a relatively safe, feasible and effective treatment for malignant esophageal strictures. PMID:24137396

    Esophageal achalasia is often associated with esophageal cancer. However, in many cases, esophageal cancer tends to be found in an advanced stage, with a poor prognosis. However, early-stage cancer was detected recently due to the advances in endoscopic instruments. In those cases, it is important to facilitate successful treatment by endoscopic submucosal dissection. We analyzed a total of six cases of esophageal cancer with achalasia in four patients treated with endoscopic submucosal dissection. Three features common to all six cases had a bearing on how endoscopic submucosal dissection was performed. First, esophageal dilatation and diminished peristalsis facilitated the performance of successful endoscopic submucosal dissection. Second, the esophageal wall was thickened, primarily with muscular tissue. Third, the submucosal layer contained abundant blood vessels that made it difficult to minimize bleeding during dissection. Those findings suggest that endoscopic submucosal dissection for early esophageal cancer associated with achalasia is a safe and potentially curative procedure. It is important, therefore, to detect esophageal cancer early.

    When radiation therapy is used for palliation of obstruction in patients with advanced esophageal carcinoma, an improvement in dysphagia can be expected in approximately 50% of patients. Major objective responses have rarely been quantitied but, in one study, were seen in 33% patients. Recurrence of dysphagia is usually seen within 2-6 months of treatment. Radiation toxicities and complications, even when used with palliative intent, can be substantial and include esophagitis, tracheoesophageal or esophageal-aortic fistula, mediastinitis, hemorrhage, pneumonitis, and myelosuppression.

    Laser-induced fluorescence spectroscopy was employed to measure fluorescence emission of normal and malignant tissue during endoscopy in patients with esophageal adenocarcinoma. A nitrogen/dye laser tuned at 410 nm was used for excitation source. The fluorescence lineshape of each spectrum was determined and sampled at 15 nm intervals from 430 nm to 716 nm. A calibration set from normal and malignant spectra were selected. Using stepwise discriminate analysis, significant wavelengths that separated normal and malignant spectra were selected. The intensities at these wavelengths were used to formulate a classification model using linear discriminate analysis. The model was used to classify additional tissue spectra from 26 malignant and 108 normal sites into either normal or malignant spectra with a sensitivity of 100 percent and specificity of 98 percent.

    This study aimed to the clarify the diagnostic efficacy of fluorescence in situ hybridization (FISH) in Kazakh patients with esophageal cancer (EC). FISH was compared with the pathological examination of biopsy specimens with DNA probes. We enrolled 20 patients, of which 15 were males and 5 females, with an average age of 58.3 years, who had abnormal esophaguses on barium radiological digital imaging. Touch preparations were performed on biopsy specimens from all of the patients and were examined using FISH for chromosomal abnormalities. We compared the FISH results with the pathology slides stained with hematoxylin and eosin. Classification, according to pathology, identified 2 cases of class II, 3 cases of IIIa, 1 case of IIIb, 2 cases of IV, 12 cases of class V and no cases of class I. The cases classified as class IIIb or higher were considered to be positive for cancer. Using histopathology, 10 cases were diagnosed with squamous cell carcinoma and 5 were diagnosed as adenocarcinoma, with one case being false-negative. Thus, the sensitivity of the pathological examination was 93% and the specificity was 100%. Using FISH, 16 cases showed aberrant copy numbers in either chromosome 3 or 17. By comparison, pathology did not reveal any false-positive or false-negative cases with a sensitivity and specificity of 100%. The centromeres of chromosome 3 copy numbers was significantly higher (p=0.035) than the centromeres of chromosome 17. Our study compared FISH to diagnose aneusomic esophageal cancer cells with the pathology of biopsied tissue. Our findings suggest that FISH is a useful and objective assay for the detection of malignant cells of esophageal cancer. In our study, the centromeres of chromosome 3 was the more sensitive probe for the diagnosis of esophageal cancer in Kazakh patients.

    The role of the metabolic syndrome in the etiology of esophageal and gastric cancer is unclear. This was a large nationwide cohort study based on data from 11 prospective population-based cohorts in Norway with long-term follow-up, the Cohort of Norway (CONOR) and the third Nord-Trøndelag Health Study (HUNT3). The metabolic syndrome was assessed by objective anthropometric and metabolic biochemical measures and was defined by the presence of at least three of the following five factors: increased waist circumference, elevated triglycerides, low high-density lipoprotein cholesterol, hypertension and high glucose. Newly diagnosed cases of esophageal adenocarcinoma, esophageal squamous-cell carcinoma and gastric adenocarcinoma were identified from the Norwegian Cancer Registry. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazard models with adjustment for potential confounders. Among 192,903 participants followed up for an average of 10.6 years, 62 developed esophageal adenocarcinoma, 64 had esophageal squamous-cell carcinoma and 373 had gastric adenocarcinoma. The metabolic syndrome was significantly associated with an increased risk of gastric adenocarcinoma (HR 1.44, 95% CI 1.14-1.82), but not associated with esophageal adenocarcinoma (HR 1.32, 95% CI 0.77-2.26) or esophageal squamous-cell carcinoma (HR 1.08, 95% CI 0.64-1.83). Increased waist circumference was associated with an increased HR of esophageal adenocarcinoma (HR 2.48, 95% CI 1.27-4.85). No significant association was found between any single component of the metabolic syndrome and risk of esophageal squamous-cell carcinoma. High waist circumference (HR 1.71, 95% CI 1.05-2.80), hypertension (HR 2.41, 95% CI 1.44-4.03) and non-fasting glucose (HR 1.74, 95% CI 1.18-2.56) were also related to an increased risk of gastric adenocarcinoma in women, but not in men. Metabolic syndrome was associated with an increased risk of gastric adenocarcinoma in women. Of

    Long non-coding RNAs (lncRNAs), transcripts as longer than 200 nt in length with a great number of varieties in human genomics, play important roles in the regulation of genetics and epigenetics including gene transcription and post-transcription. Increasing evidence have demonstrated the upregulation of lncRNAs in tumorigenesis and metastasis of esophageal cancer (EC), a type of malignant tumors particularly in Asia. In this review, we briefly discuss the profiles and functions of lncRNAs involved in the progression of EC, which may provide a new approach to improve EC diagnosis and treatment. PMID:26609239

    Abstract Background: Human papillomavirus (HPV) has been identified to be related to progression of esophageal cancer. However, the results remain controversial. A meta-analysis of epidemiologic studies was therefore conducted to address this issue. Methods: The electronic databases of MEDLINE and Excerpta Medica database were searched till April 30, 2016. Study-specific risk estimates were pooled using a random-effects model. Results: Ten studies involving a total of 1184 esophageal cancer cases were included in this meta-analysis. The pooled hazard ratio comparing HPV-positive to HPV-negative esophageal cancers was 1.03 (95% confidence interval 0.78–1.37), which was not significantly correlated with improved survival. However, HPV-16-positive patients might have a significantly favorable survival (hazard ratio 0.73, 95% confidence interval 0.44–1.21). Conclusion: The meta-analysis indicated that HPV infection may not be of prognostic utility in the evaluation of factors contributing to esophageal cancer. Further large prospective studies are encouraged to stratify survival analysis by HPV type. PMID:27861358

    Purpose: To determine clinical factors for predicting the frequency and severity of esophageal stenosis associated with tumor regression in radiotherapy for esophageal cancer. Methods and Materials: The study group consisted of 109 patients with esophageal cancer of T1-4 and Stage I-III who were treated with definitive radiotherapy and achieved a complete response of their primary lesion at Kyushu University Hospital between January 1998 and December 2007. Esophageal stenosis was evaluated using esophagographic images within 3 months after completion of radiotherapy. We investigated the correlation between esophageal stenosis after radiotherapy and each of the clinical factors with regard to tumors and therapy. For validation of the correlative factors for esophageal stenosis, an artificial neural network was used to predict the esophageal stenotic ratio. Results: Esophageal stenosis tended to be more severe and more frequent in T3-4 cases than in T1-2 cases. Esophageal stenosis in cases with full circumference involvement tended to be more severe and more frequent than that in cases without full circumference involvement. Increases in wall thickness tended to be associated with increases in esophageal stenosis severity and frequency. In the multivariate analysis, T stage, extent of involved circumference, and wall thickness of the tumor region were significantly correlated to esophageal stenosis (p = 0.031, p < 0.0001, and p = 0.0011, respectively). The esophageal stenotic ratio predicted by the artificial neural network, which learned these three factors, was significantly correlated to the actual observed stenotic ratio, with a correlation coefficient of 0.864 (p < 0.001). Conclusion: Our study suggested that T stage, extent of involved circumference, and esophageal wall thickness of the tumor region were useful to predict the frequency and severity of esophageal stenosis associated with tumor regression in radiotherapy for esophageal cancer.

    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.

    We review the current status of proteomics for esophageal cancer (EC) from a clinician's viewpoint. The ultimate goal of cancer proteomics is the improvement of clinical outcome. The proteome as a functional translation of the genome is a straightforward representation of genomic mechanisms that trigger carcinogenesis. Cancer proteomics has identified the mechanisms of carcinogenesis and tumor progression, detected biomarker candidates for early diagnosis, and provided novel therapeutic targets for personalized treatments. Our review focuses on three major topics in EC proteomics: diagnostics, treatment, and molecular mechanisms. We discuss the major histological differences between EC types, i.e., esophageal squamous cell carcinoma and adenocarcinoma, and evaluate the clinical significance of published proteomics studies, including promising diagnostic biomarkers and novel therapeutic targets, which should be further validated prior to launching clinical trials. Multi-disciplinary collaborations between basic scientists, clinicians, and pathologists should be established for inter-institutional validation. In conclusion, EC proteomics has provided significant results, which after thorough validation, should lead to the development of novel clinical tools and improvement of the clinical outcome for esophageal cancer patients. This article is part of a Special Issue entitled: Medical Proteomics.

    2016-01-01

    Background and study aims: Biodegradable (BD) esophageal stents were recently developed mainly for refractory benign strictures, but experience and available literature are limited. Patients and methods: This was a retrospective observational study. All patients who had BD stents inserted due to refractory benign esophageal strictures or malignant strictures, or were awaiting radical radiotherapy/chemotherapy or neo-adjuvant therapy and esophagectomy between March 2011 and July 2015 were included. Results: Stent placement was successful in all patients. Ten patients with benign strictures (3 male, median age 80.5 years, IQR: 68.75 – 89.5) were followed-up for a median of 171.5 weeks (IQR: 24 – 177.25). The interval between dilatations prior to the first BD stent placement (median: 34.25 days, IQR: 23.06 – 48.29) was significantly shorter than the interval between the first BD stent placement and the first intervention required (median: 149.5 days, IQR: 94.25 – 209.5) and this difference was statistically significant (P = 0.012). Ten patients with esophageal cancer (8 male, median age: 69 years, IQR: 59.25 – 80.75) were included and they were followed up for a median of 36 weeks (IQR: 26 – 58). Only 1 completed radical radiotherapy successfully, but developed refractory post-radiotherapy stricture. No one proceeded to esophagectomy and 50 % required a self-expanding metal stent (SEMS) at a median of 134 days (IQR: 100 – 263) following stent placement. Conclusions: BD stents were successfully deployed in both benign and malignant strictures. They offered a prolonged dilatation-free interval in benign strictures, yet in the majority of patients, strictures recurred. In malignant strictures, stent patency was similar to that of benign strictures, which suggests a potential value in ensuring adequate oral intake during oncologic therapy. In our cohort, however, use of stents did not contribute to improved outcome. PMID

    Palliation is often the only treatment that can be offered to patients affected by esophageal malignancy. This prospective study was carried out in order to compare two endoscopic palliative treatments: Nd:YAG laser and local injection of 3% polidocanol. We randomized 34 patients with inoperable malignancies to one of the two treatments. After the first course, 88.8% of the patients in the laser group and 81.5% in the polidocanol group were able to swallow a normal oral caloric intake. Only one major complication (esophageal perforation) was observed (polidocanol group) and was successfully treated with endoscopic placement of a prosthesis. We believe that both techniques are safe and effective for the palliation of esophageal malignant strictures but that polidocanol injection is cheap, simple, and more widely available.

    Treatment approaches for esophageal cancer include primary treatment (surgical or nonsurgical) or adjuvant treatment (preoperative or postoperative). Primary treatments include surgery alone, radiation therapy alone, and radiation therapy plus chemotherapy (combined modality therapy). Adjuvant therapies include preoperative or postoperative radiation therapy, preoperative chemotherapy, and preoperative combined modality therapy. There is considerable controversy as to the ideal therapeutic approach. This review will examine the results of these approaches as well as combined modality therapy using novel regimens.

    The incidence of reflux esophagitis increases in world, affecting approximately 20% of Western populations and its consequent lesion, Barrett's esophagus (BE), established as the primary precursor lesion of esophageal adenocarcinoma (EAC) or Barrett associated adenocarcinoma (BAA), is also increasing in incidence in Asian countries as well as Western countries. The fact that surveillance strategies have not had a major benefit in decreasing the incidence of EAC increased attention to arrest or delay the progression of BE to EAC. Since sustained inflammation and consequent oxidative stress plays core pathogenic role in reflux esophagitis, BE, and BAA, attention paid to anti-inflammatory and antioxidative agents in the treatment of reflux esophagitis. Since the risk of esophagitis is associated with hiatal hernia, body mass index, and duodenogastric reflux, and acid exposure, lifestyle modification and agents to control gastric acidity might be mainstay for treatment, but several studies consistently showed the implication of robust oxidative stress in reflux associated esophageal diseases. In this review article, the pathogenic implication of oxidative stress will be introduced in the development of reflux esophagitis, BE, and EAC. Also, since there is great interest in complete healing of reflux esophagitis and chemoprevention to prevent or slow malignant transformation, the contribution of antioxidants or antioxidative agents, which was delivered during SFRR-Asia 2015 (Chiangmai, Thailand), will be described. Also, the molecular mechanisms how the antioxidative drugs, rebamipide, ecabet sodium, and pantoprazole exerted significant protection from acids or bile acids-associated esophagitis are included.

    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 though it was included in the previous treatment ports. This suggests the possibility that the primary esophageal cancer had been induced 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.

    Objective(s): Ranking as the sixth commonest cancer, esophageal squamous cell carcinoma (ESCC) represents one of the leading causes of cancer death worldwide. One of the main reasons for the low survival of patients with esophageal cancer is its late diagnosis. Materials and Methods: We used proteomics approach to analyze ESCC tissues with the aim of a better understanding of the malignant mechanism and searching candidate protein biomarkers for early diagnosis of esophageal cancer. The differential protein expression between cancerous and normal esophageal tissues was investigated by two-dimensional polyacrylamide gel electrophoresis (2D-PAGE). Then proteins were identified by matrix-assisted laser desorption/ ionization tandem time-of-flight mass spectrometry (MALDI-TOF/TOF-MS) and MASCOT web based search engine. Results: We reported 4 differentially expressed proteins involved in the pathological process of esophageal cancer, such as annexinA1 (ANXA1), peroxiredoxin-2 (PRDX2), transgelin (TAGLN) andactin-aortic smooth muscle (ACTA2). Conclusion: In this report we have introduced new potential biomarker (ACTA2). Moreover, our data confirmed some already known markers for EC in our region. PMID:28392898

    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.

    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 < 0.05). In fetal epithelium from fetuses at gestational age 3-6 mo, PRX6 protein expression showed a declining trend with age (P < 0.05). PRX6 protein expression was significantly higher in well-differentiated esophageal cancer tissues than in poorly differentiated esophageal cancer tissues (P < 0.05). CONCLUSION Development and progression of esophageal cancer result from interactions of genetic changes (accumulation or superposition). PRX6 protein is associated with fetal esophageal development and cancer differentiation. PMID:28293090

    Esophageal cancer is one of the fastest rising forms of cancer in the Western world. Using High-Definition (HD) endoscopy, gastroenterology experts can identify esophageal cancer at an early stage. Recent research shows that early cancer can be found using a state-of-the-art computer-aided detection (CADe) system based on analyzing static HD endoscopic images. Our research aims at extending this system by applying Random Forest (RF) classification, which introduces a confidence measure for detected cancer regions. To visualize this data, we propose a novel automated annotation system, employing the unique characteristics of the previous confidence measure. This approach allows reliable modeling of multi-expert knowledge and provides essential data for real-time video processing, to enable future use of the system in a clinical setting. The performance of the CADe system is evaluated on a 39-patient dataset, containing 100 images annotated by 5 expert gastroenterologists. The proposed system reaches a precision of 75% and recall of 90%, thereby improving the state-of-the-art results by 11 and 6 percentage points, respectively.

    SUMMARY To address uncertainty of whether clinical stage groupings (cTNM) for esophageal cancer share prognostic implications with pathologic groupings after esophagectomy alone (pTNM), we report data—simple descriptions of patient characteristics, cancer categories, and non-risk-adjusted survival—for clinically staged patients from the Worldwide Esophageal Cancer Collaboration (WECC). Thirty-three institutions from six continents submitted data using variables with standard definitions: demographics, comorbidities, clinical cancer categories, and all-cause mortality from first management decision. Of 22,123 clinically staged patients, 8,156 had squamous cell carcinoma, 13,814 adenocarcinoma, 116 adenosquamous carcinoma, and 37 undifferentiated carcinoma. Patients were older (62 years) men (80%) with normal body mass index (18.5–25 mg/kg2, 47%), little weight loss (2.4 ± 7.8 kg), 0–1 ECOG performance status (67%), and history of smoking (67%). Cancers were cT1 (12%), cT2 (22%), cT3 (56%), cNO (44%), cMO (95%), and cG2–G3 (89%); most involved the distal esophagus (73%). Non-risk-adjusted survival for squamous cell carcinoma was not distinctive for early cT or cN; for adenocarcinoma, it was distinctive for early versus advanced cT and for cNO versus cN+. Patients with early cancers had worse survival and those with advanced cancers better survival than expected from equivalent pathologic categories based on prior WECC pathologic data. Thus, clinical and pathologic categories do not share prognostic implications. This makes clinically based treatment decisions difficult and pre-treatment prognostication inaccurate. These data will be the basis for the 8th edition cancer staging manuals following risk adjustment for patient characteristics, cancer categories, and treatment characteristics and should direct 9th edition data collection.

    We report data-simple descriptions of patient characteristics, cancer categories, and non-risk-adjusted survival-for patients with pathologically staged cancer of the esophagus and esophagogastric junction after resection or ablation with no preoperative therapy from the Worldwide Esophageal Cancer Collaboration (WECC). Thirty-three institutions from six continents submitted de-identified data using standard definitions: demographics, comorbidities, clinical cancer categories, and all-cause mortality from first management decision. Of 13,300 patients, 5,631 had squamous cell carcinoma, 7,558 adenocarcinoma, 85 adenosquamous carcinoma, and 26 undifferentiated carcinoma. Patients were older (62 years) men (80%) with normal body mass index (51%), little weight loss (1.8 kg), 0-2 ECOG performance status (83%), and a history of smoking (70%). Cancers were pT1 (24%), pT2 (15%), pT3 (50%), pN0 (52%), pM0 (93%), and pG2-G3 (78%); most involved distal esophagus (71%). Non-risk-adjusted survival for both squamous cell carcinoma and adenocarcinoma was monotonic and distinctive across pTNM. Survival was more distinctive for adenocarcinoma than squamous cell carcinoma when pT was ordered by pN. Survival for pTis-1 adenocarcinoma was better than for squamous cell carcinoma, although monotonic and distinctive for both. WECC pathologic staging data is improved over that of the 7th edition, with more patients studied and patient and cancer variables collected. These data will be the basis for the 8th edition cancer staging manuals following risk adjustment for patient, cancer, and treatment characteristics, and should direct 9th edition data collection. However, the role of pure pathologic staging as the principal point of reference for esophageal cancer staging is waning. © 2016 International Society for Diseases of the Esophagus.

    2014-01-01

    Cancer metastasis is an invasive process that involves the transplantation of cells into new environments. Since human placentation is also invasive, hypotheses about a relationship between invasive placentation in eutherian mammals and metastasis have been proposed. The relationship between metastatic cancer and invasive placentation is usually presented in terms of antagonistic pleiotropy. According to this hypothesis, evolution of invasive placentation also established the mechanisms for cancer metastasis. Here, in contrast, we argue that the secondary evolution of less invasive placentation in some mammalian lineages may have resulted in positive pleiotropic effects on cancer survival by lowering malignancy rates. These positive pleiotropic effects would manifest themselves as resistance to cancer cell invasion. To provide a preliminary test of this proposal, we re-analyze data from Priester and Mantel (Occurrence of tumors in domestic animals. Data from 12 United States and Canadian colleges of veterinary medicine. J Natl Cancer Inst 1971;47:1333-44) about malignancy rates in cows, horses, cats and dogs. From our analysis we found that equines and bovines, animals with less invasive placentation, have lower rates of metastatic cancer than felines and canines in skin and glandular epithelial cancers as well as connective tissue sarcomas. We conclude that a link between type of placentation and species-specific malignancy rates is more likely related to derived mechanisms that suppress invasion rather than different degrees of fetal placental aggressiveness.

    The worldwide incidence of superficial esophageal cancer (SEC) is increasing. The aim of this study is to review the systematic surgical outcomes of esophagectomy for SEC. Only manuscripts written in English and written between 1980 and 2003 were selected from MEDLINE. The keywords consisting of superficial esophageal cancer, early esophageal cancer, and early stage or superficial stage or stage I in esophageal cancer were searched. There were no exclusion criteria for published information relevant to the topics. The most representative articles were selected when there were several articles from the same institution. Case reports were excluded. DATA EXTRACTIONS: Thirty-two manuscripts were finally collected from MEDLINE and eight articles were also added from reference lists of the pertinent literatures. In evaluating the statistical analysis of the complications of the reported literature, collective method was used. The collected information was organized. The conclusions drawn from those articles showed that the overall prevalence of SEC accounted around 10% and increased to 25% in the 2000s. The overall incidence of lymph node metastasis of SEC was about 25% and its incidences in mucosal and submucosal cancer were 5 and 35%, respectively. The percentage of the cases of squamous cell carcinoma (SCC) vs adenocarcinoma (AC) widely varied depending on the geographic locations reported; most SCC cases were from the Asian countries and most AC cases were from the European countries. Clinical significance of multimodal treatment for SEC has dramatically developed in the recent era and could provide various potential therapeutic options for SEC. These concepts make it possible to individualize surgical management of SEC as part of various multimodal treatments. The operative approaches for SEC varied from minimally invasive thoracoscopic esophagectomy, limited transabdominal distal esophagectomy, conventional transthoracic esophagectomy, transhiatal esophagectomy

    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

    Background Esophageal cancer (EC) occurs commonly, especially in Asia, and is the sixth leading cause of cancer deaths worldwide. Recently, great progress has been made in research on the etiology and prevention of EC. Summary The major risk factors for esophageal squamous cell carcinoma (ESCC) are tobacco smoking and alcohol drinking, which act synergistically. Dietary parameters, including dietary carcinogens and insufficiency of micronutrients, could also be important risk factors in certain areas. A common etiological factor for both EC and some other cancers are low levels of intake of fruits and vegetables. With improvements in diet and drinking water in developing countries, the incidence of ESCC decreased. However, in economically well-developed countries, the incidence of esophageal adenocarcinoma (EAC) has markedly increased in the past 40 years. The major etiological factor for EAC is gastroesophageal reflux, which is also an etiological factor for gastric cardia adenocarcinoma (GCA). In certain areas of China, the occurrence of GCA is closely related to ESCC. Susceptibility genes for EC are starting to be discovered, and this may help to identify high-risk groups that have more need for preventive measures. Mitigation of the risk factors, early detection and treatment of precancerous lesions are effective approaches for prevention. Smoking cessation, avoidance of excessive alcohol, meat and caloric consumption, increasing physical activity and frequent consumption of vegetables and fruits are prudent lifestyle modifications for the prevention of EC as well as other diseases. Key Message The etiology of EC includes tobacco smoking, alcohol drinking, low levels of intake of fruits and vegetables as well as gastroesophageal reflux and susceptibility genes. Practical Implications A healthy lifestyle including smoking cessation, increasing physical activity, consumption of vegetables as well as reduction of alcohol intake and caloric consumption are major

    The treatment of locally advanced esophageal cancer is controversial. For patients who are candidates for surgical resection, multiple prospective clinical trials have demonstrated the advantages of neoadjuvant chemoradiation. For patients who are medically inoperable, definitive chemoradiation is an alternative approach with survival rates comparable to trimodality therapy. Although trials of dose escalation are ongoing, the standard radiation dose remains 50.4 Gy. Modern radiotherapy techniques such as image-guided radiation therapy with motion management and intensity-modulated radiation therapy are strongly encouraged with a planning objective to maximize conformity to the intended target volume while reducing dose delivered to uninvolved normal tissues.

    Fifteen patients with locally advanced esophageal cancer were treated with phototherapy. Each patient had dysphagia and weight loss before therapy and could not be operated on because of the extent of the tumor or poor performance status. Patients received a photosensitizer (hematoporphyrin derivative) 72 hours before phototherapy and were then treated by light delivered by an argon pumped dye laser or gold metal vapor laser at powers up to 2.2 W and doses of 337 J/cm2. Fourteen patients received 24 treatments. The results were all patients achieved a tumor response. The depth of response depended on the dose and dose rate of radiation. There were four of 24 local complications (mediastinitis 3, bronchoesophageal fistula 1). These occurred in patients treated with a power of greater than 1.5 W. There were two complete pathologic remissions in patients with locally advanced cancer. In conclusion, phototherapy is an effective alternative to other forms of palliation and potentially may be an alternative to surgery in selected cases of locally advanced esophageal cancer.

    Esophageal cancer is a serious malignancy with regards to mortality and prognosis. It is a growing health concern that is expected to increase in incidence over the next 10 years. Squamous cell carcinoma is the most common histological type of esophageal cancer worldwide, with a higher incidence in developing nations. With the increased prevalence of gastroesophageal reflux disease and obesity in developed nations, the incidence of esophageal adenocarcinoma has dramatically increased in the past 40 years. Esophageal cancer is staged according to the widely accepted TNM system. Staging plays an integral part in guiding stage specific treatment protocols and has a great impact on overall survival. Common imaging modalities used in staging include computed tomography, endoscopic ultrasound and positron emission tomography scans. Current treatment options include multimodality therapy mainstays of current treatment include surgery, radiation and chemotherapy. Tumor markers of esophageal cancer are an advancing area of research that could potentially lead to earlier diagnosis as well as playing a part in assessing tumor response to therapy. PMID:24834141

    Background Esophageal anastomotic leaks following cancer surgery remain a major cause of morbidity and mortality. Endoscopic interventions, including covered metal stents (cSEMS), clips, and direct percutaneous endoscopic jejunostomy (dPEJ) tubes are increasingly used despite limited published data regarding their utility in this setting. This study aimed to determine the efficacy and safety of a multi-modality endoscopic approach to anastomotic leak management following surgery for esophageal or gastric cancer. Methods We performed a retrospective review of prospectively maintained databases of gastric and esophageal operations at our hospital between January 2003 and December 2012. Included patients had surgery for esophageal or gastric cancer, demonstrated evidence of an anastomotic leak at the esophageal anastomosis, and underwent attempted endoscopic therapy. Healing was defined as clinical and radiographic leak resolution. Results Forty-nine patients with leaks underwent endoscopic management. Of the 49 patients, 31 (63%) received cSEMS, 40 (82%) had dPEJ tubes inserted, and 3 (6%) received clips. Twenty-three (47%) patients underwent a combined approach. Overall, 88% of patients achieved healing in a median of 83 days. Twenty-two of 23 patients (96%) who underwent a multi-modality endoscopic approach healed. Only one patient had a major complication associated with stent erosion into the pulmonary artery, which was successfully treated with operative repair. Conclusions Esophageal anastomotic leaks following esophageal and gastric cancer surgery can be managed successfully and safely with endoscopic therapy. Combining cSEMS for leak control and dPEJ tube placement for nutrition support was highly effective in achieving healing, without need for surgical repair. PMID:26428689

    2016-01-01

    Esophageal cancer is a lethal cancer encompassing adenocarcinoma and squamous cell carcinoma sub-types. The global incidence of esophageal cancer is increasing world-wide, associated with the increased prevalence of associated risk factors. The asymptomatic nature of disease often leads to late diagnosis and five-year survival rates of less than 15%. Current diagnostic tools are restricted to invasive and costly endoscopy and biopsy for histopathology. Minimally and non-invasive biomarkers of esophageal cancer are needed to facilitate earlier detection and better clinical management of patients. This paper summarises recent insights into the development and clinical validation of esophageal cancer biomarkers, focussing on circulating markers in the blood, and the emerging area of breath and odorant biomarkers.

    1984-06-01

    Radiation therapy has been used extensively in the management of patients with cancer of the esophagus. It has demonstrated an ability to cure a small minority of patients. Cure is likely to be limited to patients who have lesions less than 5 cm in length and have minimal, if any, involvement of lymph nodes. Esophagectomy is likely to cure a similar, small percentage of patients with the same presentation of minimal disease but has a substantial acute postoperative mortality rate and greater morbidity than irradiation. Combining surgery and either preoperative or postoperative irradiation may cure a small percentage of patients beyond the number cured with either modality alone. Radiation has demonstrated benefit as an adjuvant to surgery following the resection of minimal disease. However, radiation alone has never been compared directly with surgery for the highly select, minimal lesions managed by surgery. Radiation provides good palliation of dysphagia in the majority of patients, and roughly one third may have adequate swallowing for the duration of their illness when ''radical'' doses have been employed. Surgical bypass procedures have greater acute morbidity but appear to provide more reliable, prolonged palliation of dysphagia. Several approaches to improving the efficacy of irradiation are currently under investigation. These approahces include fractionation schedules, radiosensitizers, neutron-beam therapy, and helium-ion therapy.

    Significant disparities exist between genders for the development and progression of several gastro-intestinal (GI) diseases including cancer. Differences in incidence between men vs women for colon, gastric and hepatocellular cancers suggest a role for steroid sex hormones in regulation of GI carcinogenesis. Involvement of intrinsic gender-linked mechanisms is also possible for esophageal adenocarcinoma as its incidence is disproportionally high among men. However, the cause of the observed gender differences and the potential role of androgens in esophageal carcinogenesis remains unclear, even though the cancer-promoting role of androgen receptors (AR) shown in other cancers such as prostate and bladder suggests this aspect warrants exploration. Several studies have demonstrated expression of ARs in esophageal cancer. However, only one study has suggested a potential link between AR signaling and outcome - poorer prognosis. Two groups have analyzed data from cohorts with prostate cancer and one of these found a decreased incidence of esophageal squamous and adenocarcinoma after androgen deprivation therapy. However, very limited information is available about the effects of androgen and AR-initiated signaling on esophageal cancer cell growth in vitro and in vivo. Possible mechanisms for androgens/AR involvement in the regulation of esophageal cancer growth are considered, and the potential use of AR as a prognostic factor and clinical target is highlighted, although insufficient evidence is available to support clinical trials of novel therapies. As esophageal adenocarcinoma is a gender linked cancer with a large male predominance further studies are warranted to clarify the role of androgens and ARs in shaping intracellular signaling and genomic responses in esophageal cancer.

    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.

    The purpose of the report is to evaluate the role of radiotherapy in the treatment of stage III esophageal carcinoma and to analyze the influence of site, extension, grade of dysphagia and histology on local control and survival. Twenty males and 6 females were submitted to external beam therapy with 4-6 MV X-rays and received 60-70 Gy in fractions of 180 cGY to 200 cGy per day, 5 days a week. Radiation therapy technique was two posterior oblique portals and a single anterior field at 100 cm SAD. After 4500 cGy portals were coned down, holding the spinal cord dose below 4500 cGy. Global response to therapy was 73.1%. Median survival was 11 months. The 2-year survival rate was 12.5% in patients with lesions smaller than 5 cm and 5.5% for those with lesions greater than 5 cm. Patients with grade 2 dysphagia had a median survival of 16 months, those with grade 1, 11 months and 2 patients with grade 0, 4 and 9 months. In all patients mild to moderate esophagitis was observed. Two patients developed esophagotracheal fistula. Exclusively radiotherapy cannot be considered the treatment of choice in III stage patients. Primary chemoradiotherapy may emerge as the treatment of choice for cancer of the esophagus.

    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.

    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

    The placement of metal stents is often used as a palliative treatment for malignant esophageal stenosis. We designed a novel stent that has been used clinically since 2011, and we therefore performed a retrospective study to compare the therapeutic effects of this novel metal stent to a conventional partially covered metal stent in patients with malignant esophageal strictures. The records of 201 consecutive patients who underwent placement of either the conventional partially covered metal stents (Group A, n = 92) or the new metal stents (Group B, n = 109) in the Endoscopy Center of General Hospital of Chengdu Military Command from October 2008 to March 2013 were reviewed. The median dysphagia score significantly improved in both groups 1 week following stent placement (P < 0.001). No significant differences were observed in success rate (P = 0.910) or the complication rate (P = 0.426) between groups. Six months after stent placement, recurrent dysphagia due to stent migration, tissue ingrowth or overgrowth or food obstruction occurred in 45% and 29% of patients in the conventional stent and new stent groups, respectively. The results of this retrospective study indicate that the new modified self-expandable metal stents (SEMS) is at least as safe and effective as the conventional partially covered SEMS in treatment of malignant esophageal strictures. © 2015 International Society for Diseases of the Esophagus.

    Fifteen patients with Barrett's esophagus and dysplasia were treated with photodynamic therapy. Four patients also had early, superficial esophageal cancers and 5 had esophageal polyps. Light was delivered via a standard diffuser or a centering esophageal balloon. Eight patients maintained on omeprazole and followed for 6 - 54 months are the subject of this report. Photodynamic therapy ablated dysplastic or malignant mucosa in patients with superficial cancer. Healing and partial replacement of Barrett's mucosa with normal squamous epithelium occurred in all patients and complete replacement with squamous epithelium was found in two. Side effects included photosensitivity and mild-moderate chest pain and dysphagia for 5 - 7 days. In three patients with extensive circumferential mucosal ablation in the proximal esophagus, healing was associated with esophageal strictures which were treated successfully by esophageal dilation. Strictures were not found in the distal esophagus. Photodynamic therapy combined with long-term acid inhibition provides effective endoscopic therapy of Barrett's mucosal dysplasia and superficial (Tis-T1) esophageal cancer. The windowed centering balloon improves delivery of photodynamic therapy to diffusely abnormal esophageal mucosa.

    Prior studies showed that cell fusion between bone marrow-derived cell (BMDC) and somatic cell might be the origin of cancer stem cell. Our previous study suggested that cell fusion of human bone marrow-derived mesenchymal stem cell (MSC) with esophageal cancer cell did not generate cancer stem cells. But up to now, the origin of cancer stem cell is still ambiguous. In this study, we carried out the cell fusion experiment between hemopoietic stem cells (HSCs) and human esophageal cancer cells, and found that cell fusion slowed the growth speed of esophageal cancer cells and decreased the clone formation ability and tumorigenicity in NOD/SCID mice. In addition, cell fusion did not increase the ratio of side population (SP) cells and the resistance to chemotherapeutic drugs. Collectively, our data indicated that cell fusion between HSCs and esophageal cancer cells has a therapeutic effect rather than generate cells with characteristics of esophageal cancer stem cells.

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

    PubMed

    McLaren, Patrick J; Dolan, James P

    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.

    A 21-year-old male visited our hospital with a complaint of aggravating dysphagia and odynophagia for a few days. Esophagogastroduodenoscopy showed huge bulging mucosa with an intact surface causing luminal narrowing at 35 cm from the incisor teeth. Endoscopic ultrasonography showed an about 35 mm sized irregular margined in-homogenous hypoechoic lesion with an obscure layer of origin. Endoscopic ultrasonography fine needle aspiration revealed spindle cell proliferation without immunoreactivity for CD117, SMA, and cytokeratin. The patient underwent excision of the subepithelial lesion at the distal esophagus. On pathologic examination of the specimen, the tumor was composed of short fascicles of oval to spindle cells with eosinophilic and clear cytoplasm and vesicular nuclei. The tumor cells were positive for S-100 and SOX10 and negative for CD117, SMA, HMB-45, melan-A, cytokeratin, and CD99. The split-apart signal was detected in EWSR1 on FISH, suggesting a malignant gastrointestinal neuroectodermal tumor. At the time of writing, the patient is on radiation therapy at the operated site of esophagus and doing well, with no recurrence for three months. Malignant gastrointestinal neuroectodermal tumor is a rare gastrointestinal tumor with features of clear cell sarcoma, without melanocytic differentiation, and shows a poor prognosis. This is the first reported case of malignant gastrointestinal neuroectodermal tumor arising as subepithelial lesion in the esophagus.

    Radiotherapy for breast cancer may expose the esophagus to ionizing radiation, but no study has evaluated esophageal cancer risk after breast cancer associated with radiation dose or systemic therapy use. Nested case-control study of esophageal cancer among 289 748 ≥5-year survivors of female breast cancer from five population-based cancer registries (252 cases, 488 individually matched controls), with individualized radiation dosimetry and information abstracted from medical records. The largest contributors to esophageal radiation exposure were supraclavicular and internal mammary chain treatments. Esophageal cancer risk increased with increasing radiation dose to the esophageal tumor location (P(trend )< 0.001), with doses of ≥35 Gy associated with an odds ratio (OR) of 8.3 [95% confidence interval (CI) 2.7-28]. Patients with hormonal therapy ≤5 years preceding esophageal cancer diagnosis had lower risk (OR = 0.4, 95% CI 0.2-0.8). Based on few cases, alkylating agent chemotherapy did not appear to affect risk. Our data were consistent with a multiplicative effect of radiation and other esophageal cancer risk factors (e.g. smoking). Esophageal cancer is a radiation dose-related complication of radiotherapy for breast cancer, but absolute risk is low. At higher esophageal doses, the risk warrants consideration in radiotherapy risk assessment and long-term follow-up.

  18. Secondary malignancies following cancer chemotherapy.

    Many agents used in cancer chemotherapy are known carcinogens. However, few secondary malignancies have been definitely linked to chemotherapy, since studies on this problem are complicated by methodological problems. A causal relationship has been established between alkylating agents and leukaemia and between cyclophosphamide and bladder cancer. The risk of leukaemia peaks at 5-10 years after beginning of chemotherapy and declines steadily after its end. The interaction between chemotherapy and radiotherapy has not been fully clarified, nor has the leukaemogenic potency of individual drugs, although combinations without nitrogen mustard seem to entail a lower risk. Other tumours reported at increased incidence, in particular among Hodgkin's disease patients, for whom a carcinogenic effect of chemotherapy seems plausible, are non-Hodgkin's lymphoma and lung cancer. Other secondary solid tumors have also been reported, but for none of them an independent effect of chemotherapy has been demonstrated.

    Objective: This study was designed to compare the clinical effectiveness of intraluminal radioactive stent loaded with iodine-125 seeds implantation versus covered stent alone insertion in patients with malignant esophageal stricture. Methods: We studied two groups of patients with malignant esophageal stricture. Group A comprised 28 patients (19 men and 9 women) who underwent intraluminal radioactive stent loaded with iodine-125 seeds implantation and were followed prospectively. Group B comprised 30 patients (18 men and 12 women) who had previously received covered stent alone insertion; these patients were evaluated retrospectively. There was no crossover between the two groups during follow-up. Informed consent was obtained from each patient, and our institutional review board approved the study. The dysphagia score, overall survival rates, complication rates, and reintervention rates were compared in the two groups. Results: There were no significant differences between the two groups in terms of baseline characteristics. Stent placement was technically successful and well tolerated in all patients. The dysphagia score was improved in both groups after stent placement. The median survival was significantly longer in group A than in group B: 11 versus 4.9 months, respectively (P < 0.001). The complications of chest pain, esophageal reflux, and stent migration was more frequent in group B, but this difference did not reach statistical significance. There was no statistical difference in reintervention between two groups. Conclusions: Intraluminal radioactive stent loaded with iodine-125 seeds implantation was a feasible and practical management in treating malignant esophageal stricture and was superior to covered stent alone insertion, as measured by survival.

    The aim of this work was to evaluate the biochemical foundation and clinical merit of multimodal image-guided Raman endoscopy technique for real-time in vivo diagnosis of cancer in the esophagus during clinical endoscopic examinations. A novel fiber-optic Raman endoscopy system was utilized for in vivo esophageal Raman measurements at 785 nm laser excitation within 0.5 second under the multimodal wide-field endoscopic imaging (white light reflectance (WLR) imaging, narrow-band imaging (NBI) and autofluorescence imaging (AFI) guidance. A total of 75 esophageal tissue sites from 27 patients were measured, in which 42 in vivo Raman spectra were from normal tissues and 33 in vivo Raman spectra were from malignant tumors as confirmed by histopathology. The biomolecular modeling (non-negativity-constrained least-squares minimization (NNCLSM) utilizing six basis reference spectra from the representative biochemicals (i.e., actin, collagen, DNA, histones, triolein and glycogen) were employed to estimate the biochemical compositions of esophageal tissue. The resulting diagnostically significant fit coefficients were further utilized through linear discriminant analysis (LDA) and leave-one tissue site-out, cross validation method to develop diagnostic algorithms for esophageal cancer diagnosis. High-quality in vivo Raman spectra in the range of 800-1800 cm-1 can be acquired from normal and cancerous esophageal mucosa in real-time under multimodal endoscopic imaging guidance. Esophageal cancer tissue showed distinct Raman signals mainly associated with cell proliferation, lipid reduction, abnormal nuclear activity and neovasculation. The fit coefficients for actin, DNA, histones, triolein, and glycogen were found to be most significant for construction of the LDA diagnostic model, giving rise to an accuracy of 96.0% (i.e., sensitivity of 97.0% and specificity of 95.2%) for in vivo diagnosis of esophageal cancer. This study demonstrates that multimodal image-guided Raman

    Between January 1980 and December 1982, 183 patients with histologically confirmed carcinoma of the esophagus who were referred to a tertiary referral hospital were studied. Thirty-two (17%) patients were referred from Gassim Region at the north central part of Saudi Arabia. In contrast, only 5% of total cancer patient referrals were from this area. A case-control study showed a significant regional difference within Saudi Arabia and the most referrals from Gassim area. A prospective case-control study showed persistently high numbers of referrals from that region during 1983-1987. When patients from Gassim Region were compared with those referred from other locations, no statistical differences were noted between the two groups except for the source of drinking water. Water analysis from Gassim area showed a high solid content with elevated levels of calcium, magnesium, and to a lesser extent, chromium iron, cadmium, and cobalt. Traces of petroleum oil were found in five of six water samples from Gassim during 1983, compared with 3 of 49 samples from other areas. Mutagenicity tests on water specimens form Gassim Region indicated the presence of possible carcinogens. It is being suggested that the high prevalence of esophageal cancer in this region may be related to contamination of water by impurities such as petroleum oils. Malnutrition, particularly vitamin A deficiency, as well as other factors may have promoted such malignancies.

    Purpose: To assess the risk of esophageal cancer as second cancer among breast-cancer patients treated with radiotherapy. Methods and Materials: The records of the Finnish Cancer Registry from 1953 to 2000 were used to assess the risk of esophageal cancer as second cancer among 75,849 breast-cancer patients. Patients were treated with surgery (n = 33,672), radiotherapy (n = 35,057), chemotherapy and radiotherapy (n = 4673), or chemotherapy (n = 2,447). The risk of a new primary cancer was expressed as standardized incidence ratio (SIR), defined as the ratio of observed to expected cases. Results: By the end of 2000, the number of observed cases esophageal cancers was 80 vs. 72 expected cases (standardized incidence ratio (SIR) = 1.1, 95% Confidence Interval (CI) = 0.9 to 1.5). Among patients followed for 15 years and treated with radiotherapy, the SIR for esophageal cancer was 2.3 (95% CI = 1.4 to 5.4). No increase in risk was seen for patients treated without radiotherapy. The risk of esophageal cancer was increased among patients diagnosed during 1953 to 1974, although age at the treatment did not have marked effect on the risk estimate. Conclusion: Increased risk of second cancer in the esophagus was observed for breast-cancer patients in Finland, especially among patients with over 15 years of follow-up and treated in the earliest period, which may relate to the type of radiotherapy.

    A treatment planning study was performed to evaluate the performance of volumetric arc modulation with RapidArc (RA) against 3D conformal radiation therapy (3D-CRT) and conventional intensity-modulated radiation therapy (IMRT) techniques for esophageal cancer. Computed tomgraphy scans of 10 patients were included in the study. 3D-CRT, 4-field IMRT, and single-arc and double-arc RA plans were generated with the aim to spare organs at risk (OAR) and healthy tissue while enforcing highly conformal target coverage. The planning objective was to deliver 54 Gy to the planning target volume (PTV) in 30 fractions. Plans were evaluated based on target conformity and dose-volume histograms of organs at risk (lung, spinal cord, and heart). The monitor unit (MU) and treatment delivery time were also evaluated to measure the treatment efficiency. The IMRT plan improves target conformity and spares OAR when compared with 3D-CRT. Target conformity improved with RA plans compared with IMRT. The mean lung dose was similar in all techniques. However, RA plans showed a reduction in the volume of the lung irradiated at V{sub 20Gy} and V{sub 30Gy} dose levels (range, 4.62-17.98%) compared with IMRT plans. The mean dose and D{sub 35%} of heart for the RA plans were better than the IMRT by 0.5-5.8%. Mean V{sub 10Gy} and integral dose to healthy tissue were almost similar in all techniques. But RA plans resulted in a reduced low-level dose bath (15-20 Gy) in the range of 14-16% compared with IMRT plans. The average MU needed to deliver the prescribed dose by RA technique was reduced by 20-25% compared with IMRT technique. The preliminary study on RA for esophageal cancers showed improvements in sparing OAR and healthy tissue with reduced beam-on time, whereas only double-arc RA offered improved target coverage compared with IMRT and 3D-CRT plans.

    To estimate the nationwide mortality of esophageal cancer in China in 2012, to investigate the trends of the disease, and to provide support data for esophageal cancer prevention and control in China. Data of population-based cancer registry of China were extracted by sex and geographical area. Joinpoint software was used to analyze the trends of esophageal cancer from 2000 to 2011 using the continuous data of 22 cancer registries. Average annual percentage change rates (AAPC) were calculated, and 17 cancer registries data during 2003-2005 were analyzed. In 2012, there were estimated 210.9 thousand new cases of esophageal cancer death in China, with 149 thousand in males and 61.9 thousand in females, accounting for 9.65% of overall cancer death. The crude mortality rate of esophageal cancer in 2012 was 15.58 per 100 000, accounting for the fourth-leading cause of overall cancer deaths. The age-standardized mortality rates by world population and China population were 10.67 per 100 000 and 10.62 per 100 000, respectively. The cumulative mortality rate for age 0-74 was 1.28%. The age-specific mortality rates were increasing with age, and there was a sharp increase after 50 years of age. From 2000 to 2011, there was a slight decreasing trend for crude mortality rate, with the AAPC of -1.1% (95% CI: -1.8% to -0.5%). However, the age standardized mortality rates were decreasing significantly with the AAPC of -4.6% (95% CI: -5.7% to -3.6%). The AAPCs for age-standardized esophageal cancer mortality were -3.8% in urban areas and -2.4% in rural areas. For combined 5-year age standardized relative survival was 20.9% (95%CI: 20.2% to 21.7%) and the 1-, 3- and 5-year observed survival rates were 54.0%, 25.5%, 18.4%, respectively. There is still a heavy burden of esophageal cancer in China. Prevention and early diagnosis of the disease in esophageal cancer high-risk areas is very essential.

    The U.S. population is aging, life expectancy is increasing, and cancer is a disease associated with aging. Advances in screening and therapeutics have led to a growing number of cancer survivors who are at risk for the development of secondary malignancies. Although the risks for the development of second malignancies following a first diagnosis of cancer are well described for survivors of childhood malignancies, there are fewer data for malignancies common in older adults. With the aging of the U.S. population, and with improving survival statistics in many adult malignancies, there is an increasing need to identify those second malignancies that might develop in the older adult survivor of cancer. In this paper, we describe the types and rates of second malignancies following cancers commonly seen in older adults and review the literature on these malignancies. Comparisons are made between older and younger adults with regard to the risks for developing treatment-related cancers with different modalities. Recommendations for early detection of second malignancies are summarized, though there remains an unmet need for evidence-based guidelines for screening for second malignancies in the older adult in particular.

    AIM To perform a meta-analysis of the related studies to assess whether circulating tumor cells (CTCs) can be used as a prognostic marker of esophageal cancer. METHODS PubMed, Embase, Cochrane Library and references in relevant studies were searched to assess the prognostic relevance of CTCs in patients with esophageal cancer. The primary outcome assessed was overall survival (OS). The meta-analysis was performed using the random effects model, with hazard ratio (HR), risk ratio (RR) and 95% confidence intervals (95%CIs) as effect measures. RESULTS Nine eligible studies were included involving a total of 911 esophageal cancer patients. Overall analyses revealed that CTCs-positivity predicted disease progression (HR = 2.77, 95%CI: 1.75-4.40, P < 0.0001) and reduced OS (HR = 2.67, 95%CI: 1.99-3.58, P < 0.00001). Further subgroup analyses demonstrated that CTCs-positive patients also had poor OS in different subsets. Moreover, CTCs-positivity was also significantly associated with TNM stage (RR = 1.48, 95%CI: 1.07-2.06, P = 0.02) and T stage (RR = 1.44, 95%CI: 1.13-1.84, P = 0.003) in esophageal cancer. CONCLUSION Detection of CTCs at baseline indicates poor prognosis in patients with esophageal cancer. However, this finding relies on data from observational studies and is potentially subject to selection bias. Prospective trials are warranted. PMID:28275311

    Self-expanding metal stents are a promising alternative in the palliation of malignant esophageal obstruction, but the relative value of different stent types is not well established. During a 3-year enrollment period in four different centers, 82 consecutive patients with malignant dysphagia without tumor recurrence after surgery or esophagorespiratory fistulas received either an uncovered Wallstent (44 patients) or a knitted nitinol stent (38 patients). Age (median: 79 yr), sex (F:M = 33:67), dysphagia score (median: 3), Karnofsky score (median: 53), body mass index (median: 19), type of pretreatment, tumor stage, stricture length (median: 5.4 cm), and stricture location were comparable in both stent groups. After stent placement, median dysphagia score improved markedly in both groups by two points. Procedure-related mortality (16 vs 0%; p < 0.01), early complication rate (32 vs 8%; p < 0.01), and severe persistent pain after stent placement (23 vs 0%; p < 0.002) were higher in the Wallstent compared with the knitted nitinol stent group. In contrast, stent dysfunction (7 vs 32%; p < 0.005), reintervention rate (9 vs 34%; p < 0.005), and costs were lower in the Wallstent compared with the nitinol stent group. In malignant esophageal obstruction, both stents markedly improved dysphagia. Uncovered Wallstents seem to cause more early severe complications than knitted nitinol stents. In contrast, stent dysfunction, reintervention rate, and costs appear to be higher in the nitinol stent group.

    To evaluate the clinical effectiveness of a polyurethane-covered, retrievable, self-expandable metallic stent and hook catheter in the treatment of esophageal strictures. Stents were constructed of 0.4-mm stainless steel wire in a cylindric zig-zag configuration of six to nine bends. Four to eight stents were connected in tandem by dipping in a polyurethane solution. A nylon loop was hooked inside to each bend of the proximal portion of the stent and strung with a thread. Under fluoroscopic guidance, 22 stents were placed in 16 patients with a malignant stricture and five patients with a benign stricture. The stent was removed with a hook catheter 2 months after placement in patients with a benign stricture and when complications occurred in patients with a malignant stricture. All patients had dysphagia with ingestion of soft foods or liquids. Stent placement was technically successful and well tolerated in 20 patients. In one patient, the stent was misplaced but relocated successfully. After stent placement, all patients were able to ingest solid and/or soft foods without dysphagia. After stent removal, strictures showed improvement but recurred in two patients. Use of polyurethane-covered, retrievable expandable stents seems to be a feasible and effective method of treatment of benign and malignant esophageal strictures.

    We evaluated the effectiveness of a double-layered polytetrafluoroethylene (PTFE)-covered nitinol stent in the palliative treatment of malignant esophageal strictures. A double-layered PTFE-covered nitinol stent was designed to reduce the propensity to migration of conventional covered stent. The stent consists of an inner PTFE-covered stent and an outer uncovered nitinol stent tube. With fluoroscopic guidance, the stent was placed in 32 consecutive patients with malignant esophageal strictures. During the follow-up period, the technical and clinical success rates, complications, and cumulative patient survival and stent patency were evaluated. Stent placement was technically successful in all patients, and no procedural complications occurred. After stent placement, the symptoms of 30 patients (94%) showed improvement. During the mean follow-up of 103 days (range, 9-348 days), 11 (34%) of 32 patients developed recurrent symptoms due to tumor overgrowth in five patients (16%), tumor ingrowth owing to detachment of the covering material (PTFE) apart from the stent wire in 3 (9%), mucosal hyperplasia in 2 (6%), and stent migration in 1 (3%). Ten of these 11 patients were treated by means of placing a second covered stent. Thirty patients died, 29 as a result of disease progression and 1 from aspiration pneumonia. The median survival period was 92 days. The median period of primary stent patency was 190 days. The double-layered PTFE-covered nitinol stent seems to be effective for the palliative treatment of malignant esophageal strictures. We believe that the double-layer configuration of this stent can contribute to decreasing the stent's migration rate.

    Background Red and processed meats could increase cancer risk via several potential mechanisms involving iron, heterocyclic amines, polycyclic aromatic hydrocarbons and N-nitroso compounds. Although there have been multiple studies of meat and colorectal cancer, other gastrointestinal malignancies are understudied. Methods We estimated hazards ratios (HR) and 95% confidence intervals (CI) for the association between meat, meat components, and meat cooking by-products and risk of esophageal or gastric cancer in a large cohort study. During approximately 10 years of follow-up, we accrued 215 esophageal squamous cell carcinomas, 630 esophageal adenocarcinomas, 454 gastric cardia adenocarcinomas and 501 gastric non-cardia adenocarcinomas. Results Red meat intake was positively associated with esophageal squamous cell carcinoma (HR for the top versus bottom quintile = 1.79, 95% CI: 1.07–3.01, P for trend = 0.019). Individuals in the highest intake quintile of 2-amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline (DiMeIQx) had an increased risk for gastric cardia cancer (HR = 1.44, 95% CI: 1.01–2.07, P for trend = 0.104). Furthermore, those in the highest quintile of 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx), 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) or heme iron intake had a suggestive increased risk for esophageal adenocarcinoma (HR = 1.35, 95% CI: 0.97–1.89, P for trend = 0.022; HR = 1.45, 95% CI: 0.99–2.12, P for trend = 0.463; HR = 1.47, 95% CI: 0.99-2.20, P for trend = 0.063, respectively). Benzo[a]pyrene, nitrate and nitrite were not associated with esophageal or gastric cancer. Conclusions We found positive associations between red meat intake and esophageal squamous cell carcinoma, and between DiMeIQx intake and gastric cardia cancer. PMID:20978481

    Germline mutations in the PTEN tumor-suppressor gene cause autosomal-dominant conditions such as Cowden and Bannayan-Riley-Ruvalcaba syndromes with variable presentations, including hamartomatous gastrointestinal tumors, dermatologic abnormalities, neurologic symptoms, and elevated cancer risk. We describe a father and son with extensive hamartomatous gastrointestinal polyposis who both developed early-onset esophageal cancer. Exome sequencing identified a novel germline PTEN frameshift mutation (c.568_569insC, p.V191Sfs*11). In addition, a missense mutation of SMAD7 (c.115G>A, p.G39R) with an allele frequency of 0.3% in the Exome Variant Server was detected in both affected individuals. Fluorescence in situ hybridization for PTEN in the resected esophageal cancer specimen demonstrated no PTEN copy loss in malignant cells; however, results of an immunohistochemical analysis demonstrated a loss of PTEN protein expression. While the risks of many cancers are elevated in the PTEN hamartoma tumor syndromes, association between esophageal adenocarcinoma and these syndromes has not been previously reported. Esophageal adenocarcinoma and extensive polyposis/ganglioneuromatosis could represent less common features of these syndromes, potentially correlating with this novel PTEN frameshift and early protein termination genotype. Alternatively, because simultaneous disruption of both the PTEN and TGF-β/SMAD4 pathways is associated with development of esophageal cancer in a mouse model and because SMAD4 mutations cause gastrointestinal hamartomas in juvenile polyposis syndrome, the SMAD7 mutation may represent an additional modifier of these individuals' PTEN-mutant phenotype.

    beta-Catenin has 2 distinct roles in E-cadherin-mediated cell adhesion and carcinogenesis through APC gene mutation. One occurs at cell-adhesion sites, where cadherins become linked to the actin-based cytoskeleton. The others occur in the cytoplasm and nuclei and are thought to regulate cell transformation. We studied these different beta-catenins and evaluated their significance in carcinogenesis. Fresh surgical specimens were obtained from 22 patients with squamous-cell carcinoma of the esophagus. beta-Catenin in the free soluble fraction and the insoluble fraction was immunoblotted separately. At the same time, its localization was observed by immuno-histochemical techniques. In the normal esophageal epithelium, 91% of beta-catenin was detected in the insoluble fraction and beta-catenin staining occurred at the cell membrane, in co-existence with E-cadherin. In cancerous tissues, the amount of soluble beta-catenin was significantly (about 4-fold) higher than in normal tissues. Also, in cancerous tissues with higher amounts of soluble beta-catenin, immuno-histochemical techniques revealed the presence of beta-catenin in the cytoplasm and nuclei, as well as in the cell membrane. However, in samples with lower amounts of beta-catenin, expression was found only at the cell boundaries. The amount of soluble beta-catenin was not associated with the clinico-pathological grading of the tumors. Our results show that the accumulation of free soluble beta-catenin in the cytoplasm and nuclei frequently occurs during carcinogenesis of the squamous epithelium of the esophagus.

    In preparation for a collaborative multidisciplinary study of the pathogenesis of esophageal cancer, the authors reviewed the published literature to identify similarities and differences between Japan and China in esophageal cancer epidemiology. Esophageal squamous cell carcinoma (ESCC) is the predominant histologic type, while the incidence of esophageal adenocarcinoma remains extremely low in both countries. Numerous epidemiologic studies in both countries show that alcohol consumption and cigarette smoking are contributing risk factors for ESCC. There are differences, however, in many aspects of esophageal cancer between Japan and China, including cancer burden, patterns of incidence and mortality, sex ratio of mortality, risk factor profiles, and genetic variants. Overall incidence and mortality rates are higher in China than in Japan, and variation in mortality and incidence patterns is greater in China than in Japan. During the study period (1987–2000), the decline in age-adjusted mortality rates was more apparent in China than in Japan. Risk factor profiles differed between high- and low-incidence areas within China, but not in Japan. The association of smoking and drinking with ESCC risk appears to be weaker in China than in Japan. Genome-wide association studies in China showed that variants in several chromosome regions conferred increased risk, but only genetic variants in alcohol-metabolizing genes were significantly associated with ESCC risk in Japan. A well-designed multidisciplinary epidemiologic study is needed to examine the role of diet and eating habits in ESCC risk. PMID:23629646

    Clinical diagnosis of esophageal cancer (EC) at early stage is rather difficult. This study aimed to profile the molecules in serum and tissue and identify potential biomarkers in patients with EC. A total of 64 volunteers were recruited, and 83 samples (24 EC serum samples, 21 serum controls, 19 paired EC tissues, and corresponding tumor-adjacent tissues) were analyzed. The gas chromatography time-of-flight mass spectrometry (GC/TOF-MS) was employed, and principal component analysis was used to reveal the discriminatory metabolites and identify the candidate markers of EC. A total of 41 in serum and 36 identified compounds in tissues were relevant to the malignant prognosis. A marked metabolic reprogramming of EC was observed, including enhanced anaerobic glycolysis and glutaminolysis, inhibited tricarboxylic acid (TCA) cycle, and altered lipid metabolism and amino acid turnover. Based on the potential markers of glucose, glutamic acid, lactic acid, and cholesterol, the receiver operating characteristic (ROC) curves indicated good diagnosis and prognosis of EC. EC patients showed distinct reprogrammed metabolism involved in glycolysis, TCA cycle, glutaminolysis, and fatty acid metabolism. The pivotal molecules in the metabolic pathways were suggested as the potential markers to facilitate the early diagnosis of human EC. PMID:28512469

    Background Esophageal squamous cell carcinomas (ESCC) have poor prognosis. While combined modality of chemotherapy and radiotherapy increases survival, most patients die within five years. Development of agents that confer cancer cell-specific chemo- and radiosensitivity may improve the therapy of ESCC. We here reported the discovery of berberine as a potent radiosensitizing agent on ESCC cells. Principal Findings Berberine at low concentrations (<15 µM) substantially radiosensitized ESCC cells. X-ray induced DNA double-strand breaks (DSBs) persist longer in ESCC cells pretreated with berberine. Berberine pretreatment led to a significant downregulation of RAD51, a key player in homologous recombination repair, in ESCC cells, but not in non-malignant human cells. Downregulation of RAD51 by RNA interference similarly radiosensitized the cancer cells, and, conversely, introduction of exogenous RAD51 was able to significantly counteract the radiosensitizing effect of berberine, thus establishing RAD51 as a key determinant in radiation sensitivity. We also observed that RAD51 was commonly overexpressed in human ESCC tissues, suggesting that it is necessary to downregulate RAD51 to achieve high radio- or chemotherapeutic efficacy of ESCC in clinic, because overexpression of RAD51 is known to confer radio- and chemoresistance. Conclusions/Significance Berberine can effectively downregulate RAD51 in conferring radiosensitivity on esophageal cancer cells. Its clinical application as an adjuvant in chemotherapy and radiotherapy of esophageal cancers should be explored. PMID:21858113

    The histone deacetylase (HDAC) inhibitor vorinostat has received significant attention in recent years as an ‘epigenetic’ drug used to treat solid tumors. However, its mechanisms of action are not entirely understood, particularly with regard to its interaction with the aberrations in 3D nuclear structure that accompany neoplastic progression. We investigated the impact of vorinostat on human esophageal epithelial cell lines derived from normal, metaplastic (pre-cancerous), and malignant tissue. Using a combination of novel optical computed tomography (CT)-based quantitative 3D absorption microscopy and conventional confocal fluorescence microscopy, we show that subjecting malignant cells to vorinostat preferentially alters their 3D nuclear architecture relative to non-cancerous cells. Optical CT (cell CT) imaging of fixed single cells showed that drug-treated cancer cells exhibit significant alterations in nuclear morphometry. Confocal microscopy revealed that vorinostat caused changes in the distribution of H3K9ac-marked euchromatin and H3K9me3-marked constitutive heterochromatin. Additionally, 3D immuno-FISH showed that drug-induced expression of the DNA repair gene MGMT was accompanied by spatial relocation toward the center of the nucleus in the nuclei of metaplastic but not in non-neoplastic cells. Our data suggest that vorinostat’s differential modulation of 3D nuclear architecture in normal and abnormal cells could play a functional role in its anti-cancer action. PMID:27503568

    Determining what defines an adequate esophageal resection to optimize long-term outcomes in esophageal cancer is an elusive goal. The primary reason for this ambiguousness is the almost total lack of good quality prospective randomized surgical trials that examine this question adequately. Most available data are derived from small retrospective series typically representing single institution series and their treatment biases. The intent of this article is to identify the goals of an appropriate esophagectomy for cancer, essentially defining the targets that should be achieved from an operation.

    The association of gastroesophageal reflux disease (GERD) and esophageal cancer is well known. The carcinogenic properties of the gastroduodenal contents may also lead to cancer in target organs for GERD especially considering that they do not have intrinsic protective mechanisms as found in the esophagus. This review focuses on the putative relation between GERD and non-esophageal cancer. Most of the papers reviewed are far from ideal to prove the relationship of extra-esophageal cancer and GERD since a small number of patients is presented, most do not control cases based on tobacco usage and obesity, and the diagnosis of GERD is variable, not always from an objective measurement such as pH monitoring but relying on symptoms in most reports. Nevertheless, head and neck and lung cancer have a growing incidence parallel to GERD and a shift towards non-smoking, female gender and adenocarcinoma (compared to squamous cell carcinoma) is arising, similar to the example of esophageal cancer with the exception of the female gender.

    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.

    AIM To determine the association of p53, carcinoembryonic antigen (CEA) and CA19-9 protein expression with esophageal carcinogenesis. METHODS An iodine staining endoscopic screening program of esophageal lesions was carried out in the high-incidence area of Feicheng County, China. Seventy-seven patients with basal cell hyperplasia (BCH), 247 with low-grade dysplasia (LGD), 51 with high-grade dysplasia (HGD), 134 with invasive cancer, and 80 normal controls diagnosed by mucous membrane biopsy pathology were enrolled. Immunohistochemical detection of p53, CEA and CA19-9 proteins was performed. In the ROC curve analysis, the expression of a single biomarker and the expression of a combination of biomarkers were used to predict the risk of these four esophageal lesions. RESULTS The positive rates of p53 protein expression in invasive cancer, HGD, LGD, BCH and the normal control groups were 53.0%, 52.9%, 35.6%, 27.3% and 20.0%, respectively; the positive rates of CA19-9 protein expression were 44.0%, 33.3%, 16.5%, 9.2% and 6.2%, respectively; the positive rates of CEA protein expression were 74.6%, 60.8%, 23.3%, 23.7% and 16.2%, respectively. The positive rates of the combined expression of the three biomarkers were 84.3%, 76.5%, 47.6%, 42.9% and 27.5%, respectively. In the receiver operating characteristic curves of the combination of the three biomarkers, the specificity was 88.8% for the normal controls, and the sensitivity was 58.2% for invasive cancer, 25.5% for HGD, 11.2% for LGD, and 6.5% for BCH. CONCLUSION p53, CEA and CA19-9 protein expression was correlated with esophageal carcinogenesis, and testing for the combination of these biomarkers is useful for identifying high-risk patients with precancerous lesions.

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.

    New treatment strategies are needed to improve outcomes for patients with esophageal cancer. With five-year survival rates less than 25 percent, this is one of the deadliest forms of cancer. There are two main types of esophageal cancer—squamous cell carcinoma and adenocarcinoma. Esophageal adenocarcinoma is frequently preceded by Barrett’s esophagus, a chronic inflammatory condition caused by gastroesophageal reflux. It is known that communication between tumor cells and the immune system can alter the behavior of tumor cells, and chronic inflammation has been implicated in several types of human cancers, including cancer of the esophagus.

    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 < 0.001. The presence of 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 cancer is the eighth most common type of cancer in the world, and the sixth most common cause of mortality from cancer. Alcohol consumption is the major risk factor for esophageal cancer, due to the worldwide prevalence and high carcinogenicity of the ethanol metabolite. In epidemiological studies, the efficiency of alcohol intake to enhance the risk of esophageal cancer is altered by daily ethanol consumption, type of alcoholic beverages ingested, time since quitting drinking, age of drinking initiation, differences in population and subtypes of esophageal cancer. Corresponding factors, including gene polymorphisms, tobacco smoking, oral microorganisms and folate deficiency, reveal a synergistic effect in concurrent alcohol users that may lead to an increased risk of developing esophageal cancer. Consequently, esophageal cancer prevention involves multiple aspects, including quitting drinking and smoking, maintaining an adequate oral health and ingesting adequate quantities of folate, particularly in genetically high-risk populations.

    In the last years, interesting advances have been reported in the treatment of infrequent digestive tumors. The increasing development of new targeted therapies in human cancer has also impacted in these rare gastrointestinal malignancies providing a wide range of possibilities in the design of future clinical trials. The inhibition of angiogenesis and the blockage of the epidermal growth factor receptor pathway have provided the most interesting activity in recently reported studies for esophageal and biliary tract carcinomas. Additionally, several targeted therapies have been developed to target the main kinase proteins of the most important pathways of these malignancies. The results of the biggest phase III trial in locally advanced anal carcinoma have been recently published. Finally, the inhibition of epidermal growth factor receptor has also showed promising activity in anal carcinomas. Recent advances in the knowledge of molecular mechanism of carcinogenesis have led to meaningful changes in the management of gastrointestinal cancers. Although the major advances in targeted therapy have been introduced in the treatment of colorectal cancer, new interesting approaches have been reported in less frequent gastrointestinal tumors such as esophageal, biliary tract, and anal canal carcinoma opening a new hope in the treatment of these rare tumors in the molecular targeted therapy era.

    Objective: To identify risk factors for complications after resection for esophageal or cardia cancer. Summary Background Data: Knowledge of risk factors for complications after esophageal resection for cancer is sparse, and prospective population-based studies are lacking. Methods: A prospective, nationwide, population-based study was conducted in Sweden in April 2, 2001 through December 31, 2003. Details about tumor characteristics and stage, surgical procedures, and complications were collected prospectively from the Swedish Esophageal and Cardia Cancer register. Medical records and specific charts from surgical procedures, histopathology reports, and intensive care units were continuously scrutinized. Multivariable logistic regression analyses were used to estimate relative risks and their 95% confidence intervals. Results: Among 275 patients undergoing surgical resection for esophageal or cardia cancer, 122 (44%) had at least one predefined complication. Operation by low-volume surgeons (<5 operations annually) were followed by more anastomotic leakages than those by surgeons with higher volume (odds ratio, 7.86; 95% confidence interval, 2.13–29.00). Hand-sewn and stapled anastomoses did not differ regarding risk of anastomotic leakage. Among cardia cancer patients, transthoracic approach resulted in more respiratory complications compared with transhiatal (abdominal only) approach (odds ratio, 4.78; 95% confidence interval, 1.66–13.76). Older age, adjuvant oncologic therapy, and higher preoperative bleeding volume nonsignificantly increased the risks of complications, while no influence of sex or tumor stage was found. Conclusions: High-volume esophageal surgeons seem to lower the risk of anastomotic leakage. More large-scale studies are warranted to establish the roles of the other potentially important risk factors suggested in our study. PMID:16432353

    AIM: To identify risk factors associated with esophageal cancer in Zambia and association between dietary intake and urinary 8-iso prostaglandin F2α (8-isoPGF2α). METHODS: We conducted a prospective, case control study at the University Teaching Hospital. Subjects included both individuals admitted to the hospital and those presenting for an outpatient upper endoscopy. Esophageal cancer cases were compared to age and sex-matched controls. Cases were defined as patients with biopsy proven esophageal cancer; controls were defined as subjects without endoscopic evidence of esophageal cancer. Clinical and dietary data were collected using a standard questionnaire, developed a priori. Blood was collected for human immunodeficiency virus (HIV) serology. Urine was collected, and 8-isoPGF2α was measured primarily by enzyme-linked immunosorbent assay and expressed as a ratio to creatinine. RESULTS: Forty five controls (mean age 54.2 ± 15.3, 31 male) and 27 cases (mean age 54.6 ± 16.4, 17 males) were studied. Body mass index was lower in cases (median 16.8) than controls (median 23.2), P = 0.01. Histopathologically, 25/27 (93%) were squamous cell carcinoma and 2/27 (7%) adenocarcinoma. More cases smoked cigarettes (OR = 11.24, 95%CI: 1.37-92.4, P = 0.02) but alcohol consumption and HIV seropositivity did not differ significantly (P = 0.14 for both). Fruit, vegetables and fish consumption did not differ significantly between groups (P = 0.11, 0.12, and 0.10, respectively). Mean isoprostane level was significantly higher in cases (0.03 ng/mg creatinine) than controls (0.01 ng/mg creatinine) (OR = 2.35, 95%CI: 1.19-4.65, P = 0.014). CONCLUSION: Smoking and isoprostane levels were significantly associated with esophageal cancer in Zambians, but diet, HIV status, and alcohol consumption were not. PMID:26973419

    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.

    Tumors of the gastrointestinal tract are among the most frequent human malignancies and account for approximately 30% of cancer-related deaths worldwide. Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors that control diverse cellular functions such as proliferation, differentiation, and cell death. Owing to their involvement in so many processes, they play crucial roles also in the development and physiology of the gastrointestinal tract. Consistently, PPARs deregulation has been implicated in several pathophysiological conditions, including chronic inflammation and cancer development. This paper summarizes the current knowledge on the role that the various PPAR isoforms play in the pathogenesis of the esophageal, gastric, and intestinal cancer. Elucidation of the molecular mechanisms underlying PPARs' signaling pathways will provide insights into their possible use as predictive biomarkers in the initial stages of the process. In addition, this understanding will provide the basis for new molecular targets in cancer therapy and chemoprevention.

    Cancer stem cells (CSCs) are a distinct population in tumors and cause cancer relapse and metastasis. Thus, treating CSCs are believed to be potential to cure rapidly growing and highly metastatic cancers. To date, CSCs in esophageal cancer have not been characterized. In the current study, we detected significant higher levels of placental growth factor (PLGF) and matrix metalloproteinase 9 (MMP9) in the esophageal cancers with metastasis, compared to those without metastasis, in which the expression levels of PLGF and MMP9 strongly correlated with each other. Thus, we used a human esophageal cancer cell line, TE-1, to examine the cross talk of PLGF and MMP9. We found that the levels of PLGF in TE-1 cells positively affected the levels of MMP9, while the levels of MMP9 did not affected the levels of PLGF, suggesting that PLGF may activate MMP9 in esophageal cancer cells. Then, we separated PLGF-positive and PLGF-negative TE-1 cells that had been transfected with a GFP reporter under a PLGF promoter by flow cytometry. We found that PLGF-positive cells grew significantly faster than PLGF-negative cells both in vitro and in vivo in a stereotactical implantation model, suggesting that PLGF-positive cells are likely CSCs in esophageal cancer. Taken together, we demonstrate that PLGF-positive cells appear to be CSCs in esophageal cancer, and they may release PLGF to promote cancer metastasis through MMP9 activation.

    The role of metallic stents in the palliation of esophageal cancer is well established. Self-expanding metal stents (SEMSs) are frequently used, as they provide an effective and safe method of relieving malignant dysphagia. A number of complications are associated with the use of SEMSs, including esophageal perforation. We report a case of thoracic discitis occurring in a patient with advanced esophageal malignancy, treated with SEMSs. We propose that the likely etiology in this patient was esophageal perforation by a metallic stent.

    On cytosmears of esophageal epithelium of individuals from high-risk area of esophageal cancer squamous epithelial cells, according to standard cytologic diagnostic criteria, can be categorized as normal, hyperplasia, severely dysplastic grade I and grade II, nearly-carcinoma and early carcinoma. Cytosmears from 60 patients, 10 for each category, were studied with a semiautomatic image analysis system. Thirteen morphologic parameters so obtained were further analyzed by computer-based stepwise regression and linear correlation analyses. The results showed that the following 5 parameters could be used to judge the nature of the cells, i.e. a) cytoplasmic area, b) cytoplasmic mean diameter, c) cytoplasmic form factor, d) nuclear form factor and e) N/C ratio. Comparing with cells of the other categories, values of the first 4 parameters for early cancer cells were decreased whereas that of the fifth parameter was significantly increased. From normal to hyperplastic and to dysplastic cells, the nuclear area and mean nuclear diameter were gradually increasing. Therefore, they were the major parameters in judging the degree of hyperplasia and dysplasia. These numerical features of morphologic quantitation conformed with the cytologic diagnostic criteria for cancer, hyperplasia and dysplasia under light microscope. It indicates that visual judgement is relatively accurate and application of the ocular micrometer to measure the cells would make this grading more objective.

    Background: Heavy metal pollution in farm soils is a grave concern in Taiwan. Previously, we found the incidence of oral cancer (OC) correlated positively with levels of nickel and arsenic in farm soils. Many OC patients have a second malignancy, among which esophageal cancer (EC) is the most common one in Taiwan. Objectives: We aimed to investigate whether these two cancers share some common risk factors. Methods: Taiwan began a compulsory national health insurance program in 1995. We used a database from this program to calculate the prevalence of EC and OC in Taiwan. We compared the prevalence of EC with prevalence of betel nut chewers in adults and the information of heavy metal in farm soils to look for any association. Results: The prevalence of OC and prevalence of EC were strongly correlated. The prevalence of betel nut chewing correlated with OC prevalence, but not with EC prevalence. An increased prevalence (1.9 fold) of EC was found where the farm soils contained high levels of nickel. Meanwhile, among the eight heavy metals studied, only the levels of nickel in the farm soils correlated statistically with the prevalence of EC. Conclusion: Nickel is probably a common environmental risk factor for esophageal cancer and oral cancer. PMID:27698910

    Using the Cancer Environment Registry of Sweden, which links the 1960 census information on employment with cancer incidence data from 1961-1979, we conducted a systematic, population-based assessment of esophageal cancer incidence by industry and occupation for men in Sweden. A general reduction in esophageal cancer incidence was found among agricultural and professional workers, whereas excess incidence was found among business, sales, and some craftsmen and production jobs. Elevated incidence was associated with several specific industries, including the food (SIR = 1.3, p < 0.05), beverage and tobacco (SIR = 1.8, p < 0.05) industries, vulcanizing shops within the rubber industry (SIR = 4.7, p < 0.01), and certain automotive building industries. Incidence also was increased among brewery workers (SIR = 4.2, p < 0.01) and butchers (SIR = 2.1, p < 0.01), and among individuals with certain service jobs, particularly waiters in the hotel and restaurant industry (SIR = 3.1, p < 0.01). Some of the occupational associations may be explained by lifestyle factors such as alcohol drinking and smoking, whereas others are specific and tend to support those of earlier investigations. This study adds to the evidence of a small but possibly important role of occupation in esophageal cancer etiology.

    Summary Background Long-term survival in patients with esophageal cancer remains dismal despite the recent improvements in surgery, the advances in radiotherapy (RT) technology, and the refinement of systemic treatments, including the advent of targeted therapies. Although surgery constitutes the treatment of choice for early-stage disease (stage I), a multimodal approach, including preoperative or definitive chemoradiotherapy (CRT) and perioperative chemotherapy, is commonly pursued in patients with locally advanced disease. Methods A review of the literature was performed to assess the role of RT, alone or in combination with chemotherapy, in the management of esophageal cancer. Results Evidence from large, randomized phase III trials and meta-analyses supports the application of perioperative chemotherapy alone or preoperative concurrent CRT in patients with lower esophageal and esophagogastric junction adenocarcinomas. Preoperative CRT but not preoperative chemotherapy alone is now routinely used in patients with locally advanced squamous cell carcinoma (SCC). Additionally, definitive CRT without surgery has also emerged as a valuable approach in the management of resectable esophageal SCC to avoid surgery-related morbidity and mortality, whereas salvage surgery is reserved for those with persistent disease. Furthermore, brachytherapy offers a valuable option in the palliative treatment of patients with locally advanced, unresponsive disease. Fluorodeoxyglucose-positron emission tomography (FDG-PET) can facilitate a more accurate treatment response assessment and patient selection. Finally, the development of modern RT techniques, such as intensity-modulated and image-guided RT as well as FDG-PET-based RT planning, could further increase the therapeutic ratio of CRT. Conclusion Altogether, CRT constitutes an important tool in the treatment armamentarium for esophageal cancer. Further optimization of CRT using modern technology and imaging, targeted therapies

    Background Positive esophageal proximal resection margin (ERM+) following esophagectomy was considered as incomplete or R1 resection. The clinicopathological data and long-term prognosis of esophageal cancer (EC) patients with ERM+ after esophagectomy were still unknown. Therefore, the aim of this study was to assess the clinical significance of ERM+ and its therapeutic option. Methods From November 2008 to December 2014, 3,594 patients with histologically confirmed EC underwent radical resection in our department. Among them there were 37 patients (1.03%) who had ERM+. ERM+ was defined as carcinoma or atypical hyperplasia (severe or moderate) at the residual esophageal margin in our study. For comparison, another 74 patients with negative esophageal proximal resection margin (ERM−) were propensity-matched at a ratio of 1:2 as control group according to sex, age, tumor location and TNM staging. The relevant prognostic factors were investigated by univariate and multivariate regression analysis. Results In this large cohort of patients, the rate of ERM+ was 1.03%. The median survival time was 35.000 months in patients with ERM+, significantly worse than 68.000 months in those with ERM− (Chi-square =4.064, P=0.044). Survival in patients with esophageal residual atypical hyperplasia (severe or moderate) was similar to those with esophageal residual carcinoma. Survival rate in stage I–II was higher than that in stage III–IV (Chi-square =27.598, P=0.000) in ERM−; But there was no difference between the two subgroups of patients in ERM+. Furthermore, in those patients with ERM+, survival was better in those who having adjuvant therapy, compared to those without adjuvant therapy (Chi-square =5.480, P=0.019). And the average survival time which was improved to a well situation for ERM+ patients who have adjuvant therapy was 68.556 months which is comparable to average survival time (65.815 months) of ERM− for those patients who are at earlier stages

    The ingestion of hot food and beverages has repeatedly been postulated as a risk factor for cancer of the esophagus. Although several studies have been performed on the correlation of the consumption of hot tea and esophageal cancer, no research has heretofore documented, by actually measuring, the temperature at which the tea is consumed. Therefore, a tea temperature measurement study was carried out in the Caspian Littoral of Iran, where the frequency of esophageal cancer is the highest in the world. The study was conducted during a population-food-habits survey in 1968 to 1969, which was performed before statistics were available regarding the incidence rate or geographic distribution of this disease in the region. Ten years later, when the results of the Caspian Cancer Registry were analyzed, the data from this nutritional study was compared with the regional distribution of esophageal cancer. A geographic correlation exists between the frequency of consumption of hot tea and the incidence of esophageal cancer. Seventy-two percent of the people in the low-risk region of esophageal cancer drank their tea at the relatively moderate temperature of below 55 degrees C, compared with only 3% in the high risk region. More importantly, 62% of the adult population in the high-risk region, as opposed to 19% in the low-risk region, drank their tea at a temperature of over 65 degrees C. In addition to the thermal irritation of hot tea, the following considerations cannot be ignored: the carcinogenicity role of tannins; the cancer-promoting effect of phenols; and the absorption facilitating role of hot tea. Alcohol and tobacco, the most important risk factors for cancer of the esophagus in many countries, play a negligible role in the cause of this disease in northern Iran. In this region, nutritional deficiencies--a special diet for pregnant women composed of sour pomegranite seeds, black pepper, and garlic; consumption of bread contaminated with silica fibre; and

    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 of 41.4 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 post-operative 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 phase II trial of neoadjuvant and adjuvant CRT) and QUINTETT (a phase III trial of neoadjuvant vs adjuvant therapy with quality of life analysis). These trials hopefully will shed more light on the future management of esophageal cancer. PMID:25132924

    We report a case of adenocarcinoma of the esophagus presenting as an orbital metastasis prior to the primary diagnosis. A 66-year-old white male presented to his ophthalmologist with right orbital swelling for several months. Magnetic resonance imaging revealed a supraorbital infiltrative mass. Pathology from the mass revealed findings consistent with adenocarcinoma of gastrointestinal origin. Upper endoscopy revealed distal esophageal stricture and irregularities. Pathology from the esophagus showed the same malignancy found in the orbit. An orbital swelling can manifest as the initial presentation of metastatic disease and should be taken seriously to avoid delay in diagnosis and treatment. PMID:27921053

    Leucine aminopeptidases (LAPs) were associated with tumor cell proliferation, invasion and/or angiogenesis. We aimed to examine the biological function of LAP3 in esophageal squamous cell carcinoma (ESCC). LAP3 expressions were examined in human ESCC tissue and cell lines ECA109 and TE1 cells. Recombinant pSilencer4.1-LAP3-shRNA was transfected into ECA109 cells to silence LAP3 expression. The effects of LAP3 silencing on ECA109 cell proliferation in vitro were evaluated. Flow cytometry profiling was used to detect the differentiate cell cycle distribution in LAP3-silenced ECA109 cells. Wound-healing assay and transwell assay were used to examine the activities of migration and invasion in LAP3-silenced ECA109 cells. We overexpressed LAP3 in TE1 cells to find out the corresponding results. LAP3 expression level was abundance in ESCC tissue. LAP3 silencing significantly reduced ECA109 cell proliferation and colony formation. The knockdown of LAP3 resulted in cell cycle arrest at G1-phase. Moreover, over expression of LAP3 favors TE1 cell proliferation and invasiveness which also confirms its contribution in malignant development. We came to the conclusion that LAP3 contributed to ESCC progression by overcoming cell cycle arrest. The proliferative and migration effects of LAP3 might contribute to malignant development of human ESCC.

    Periostin, also known as osteoblast-specific factor 2, is a cell-adhesion protein with pleiotropic properties. The protein serves a vital role in the maintenance and development of tooth and bone tissue, in addition to cardiac development and healing. Periostin levels are increased in several forms of cancer, including pancreatic, ovarian, colon, lung, breast, gastric, thyroid, and esophageal head and neck carcinomas. The present review highlights the key role of periostin in tumorigenesis, particularly in increasing cell survival, invasion, angiogenesis, epithelial-mesenchymal transition and metastasis of carcinoma cells by interacting with numerous cell-surface receptors, including integrins, in the phosphoinositide 3-kinase-Akt pathway. In addition, periostin actively affects the canonical Wnt signaling pathway of colorectal tumorigenesis. The current review focused on the involvement of periostin in the development of colorectal, esophageal and gastric cancer. PMID:27446351

    We wanted to determine factors affecting survival rates of benefits to, and complications in patients with esophageal cancer treated with photodynamic therapy. From 1982 to January 1994, we used photodynamic therapy to treat 77 patients with esophageal carcinoma and evaluated survival to July 1994. All patients had failed, refused, or were ineligible for surgical intervention, ionizing radiation therapy, or chemotherapy. The only significant variable affecting survival was clinical stage. Median survival after photodynamic therapy was as follows: all patients, 6.3 months (mean survival, 9.2 months); stage I, not reached; stage II, 12 months; stage III, 6.2 months; and stage IV, 3.5 months. For stages III and IV, a Karnofsky performance status of 70 or higher had a significant effect. For stage III, the median survival was 6.3 months when the Karnofsky performance status was equal to or greater than 70 and 3.5 months when it was less than 70. For stage IV, the median survival was 5.5 months when the Karnofsky performance status was equal to or greater than 70 and 2.5 months when it was lower than 70. Seven stage I patients with no treatment prior to photodynamic therapy had an estimated 5-year survival rate of 62%. Three patients with stage I invasive adenocarcinoma and Barrett's mucosa diagnosed when they underwent endoscopy for dysphagia were alive with no evidence of disease 17, 44, and 59 months after photodynamic therapy. Photodynamic therapy for esophageal carcinoma caused minimal complications and no procedure-related deaths. Photodynamic therapy can be considered an alternative treatment for patients with Barrett's esophagus with severe dysplasia or patients with stage I carcinoma who are under consideration for operation but are high surgical risks. The length of palliation for patients having "noncurative" treatment was equal to or better than that reported historically for most other treatment regimens.

    Background. Intra-abdominal metastases of invasive lobular breast cancer (ILBC) may be insidious. We report a case of metastatic ILBC that presented with dysphagia within weeks of a negative mammogram and before the development of intra-abdominal symptoms. Case. A 70-year-old female developed esophageal dysphagia. She underwent EGD which showed a short segment of stricture of the distal esophagus without significant mucosal changes. Biopsy was unremarkable and patient underwent lower esophageal sphincter (LES) dilation. Severe progressive dysphagia led to esophageal impaction and three LES dilatations. CT scan showed bilateral pleural effusions, more prominent on right side, and ascites. The pleural effusions were transudative. Repeat EGD with biopsy showed lymphocytic esophagitis, and she was started on swallowed fluticasone. Abdominal ultrasound with Doppler showed that the main portal vein had atypical turbulent flow that was felt to possibly be due to retroperitoneal process. The patient underwent diagnostic laparoscopy which revealed diffuse punctate lesions on the peritoneum. Pathology was consistent with metastatic ILBC. Conclusion. Dysphagia in the setting of peritoneal carcinomatosis from metastatic ILBC is a rare finding. The case highlights the importance of metastatic ILBC as a differential diagnosis for female patients with progressive dysphagia and associated ascites or pleural effusions. PMID:28191357

    Introduction After definitive treatment of esophageal cancer, patients are at high risk for recurrence. Consistent follow-up is important for detection and treatment of recurrence. The optimal surveillance regimen remains undefined. We investigated posttreatment recurrence patterns and methods of detection in survivors of esophageal cancer. Methods We retrospectively studied a cohort of patients who had undergone surgical resection for esophageal cancer at our institution between 1996 and 2010. Routine computed tomography (CT) scan and upper endoscopy were performed for surveillance. Results In total, 1147 patients with resected esophageal adenocarcinoma or squamous cell carcinoma were included (median follow-up, 46 months). Of these, 723 (63%) had received neoadjuvant therapy before surgery. During follow-up, there were 595 deaths (52%) and 435 recurrences (38%) (distant [55%], locoregional [28%], or both [17%]). Half of recurrences were detected as a result of symptoms (n = 217), 45% by routine chest and abdominal CT scan (n = 194), and 1% by surveillance upper endoscopy (n = 6). The recurrence rate decreased from 27 per 100 person-years in posttreatment year 1 to 4 per 100 person-years in year 6. In the first 2 years, the rate of recurrence was higher among patients who had received neoadjuvant therapy (35 per 100 person-years) than among those who had not (14 per 100 person-years) (p < 0.001). Conclusions The incidence of recurrence is high after esophagectomy for cancer. Surveillance endoscopy has limited value for detection of asymptomatic local recurrence. The yield from follow-up scans diminishes significantly after the sixth year; surveillance scans after that point are likely unnecessary. PMID:24389438

    AIM: To assess whether the molecular markers of malignant tumors could improve the understanding of tumor charact-eristics, and to observe the characteristics of expression of cell cycle markers Ki-67 and cyclin 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 immun-ohistochemistry 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 (×200) 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 immuno-staining 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. PMID:15902736

    Cigarette smoking at diagnosis or during therapy correlates with poor outcome in patients with lung and esophageal cancers, yet the underlying mechanisms remain unknown. In this study, we observed that exposure of esophageal cancer cells to cigarette smoke condensate (CSC) led to upregulation of the xenobiotic pump ABCG2, which is expressed in cancer stem cells and confers treatment resistance in lung and esophageal carcinomas. Furthermore, CSC increased the side population of lung cancer cells containing cancer stem cells. Upregulation of ABCG2 coincided with increased occupancy of aryl hydrocarbon receptor, Sp1, and Nrf2 within the ABCG2 promoter, and deletion of xenobiotic response elements and/or Sp1 sites markedly attenuated ABCG2 induction. Under conditions potentially achievable in clinical settings, mithramycin diminished basal as well as CSC-mediated increases in AhR, Sp1, and Nrf2 levels within the ABCG2 promoter, markedly downregulated ABCG2, and inhibited proliferation and tumorigenicity of lung and esophageal cancer cells. Microarray analyses revealed that mithramycin targeted multiple stem cell-related pathways in vitro and in vivo. Collectively, our findings provide a potential mechanistic link between smoking status and outcome of patients with lung and esophageal cancers, and support clinical use of mithramycin for repressing ABCG2 and inhibiting stem cell signaling in thoracic malignancies.

    The local control effect of esophagectomy with three-field lymph node dissection (3FLD) is reaching its limit pending technical advancement. Minimally invasive esophagectomy (MIE) by thoracotomy is slowly gaining acceptance due to advantages in short-term outcomes. Although the evidence is slowly increasing, MIE is still controversial. Also, the results of treatment by surgery alone are limiting, and multimodality therapy, which includes surgical and non-surgical treatment options including chemotherapy, radiotherapy, and endoscopic treatment, has become the mainstream therapy. Esophagectomy after neoadjuvant chemotherapy (NAC) is the standard treatment for clinical stages II/III (except for T4) esophageal cancer, whereas chemoradiotherapy (CRT) is regarded as the standard treatment for patients who wish to preserve their esophagus, those who refuse surgery, and those with inoperable disease. CRT is also usually selected for clinical stage IV esophageal cancer. On the other hand, with the spread of CRT, salvage esophagectomy has traditionally been recognized as a feasible option; however, many clinicians oppose the use of surgery due to the associated unfavorable morbidity and mortality profile. In the future, the improvement of each treatment result and the establishment of individual strategies are important although esophageal cancer has many treatment options. PMID:28003586

    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. PMID:25386186

    MicroRNAs (miRNAs) act as key regulators of multiple cancers. MicroRNA-506 (miR-506) functions as a tumor suppressor in various types of cancers. However, its role in esophageal cancer remains unclear. In our study, we found that miR-506 was significantly down-regulated in esophageal cancer tissues and cell lines. In vitro assay, our results showed that ectopic over-expression of miR-506 inhibited esophageal cancer cells proliferation, meanwhile, cells proliferation was promoted by miR-506 inhibition. In exploring mechanisms underlying the inhibitive role, we found that miR-506 significantly decreased the expression and transcription activity of cAMP responsive element binding protein 1 (CREB1). CREB1, tumor oncogene, exhibited significantly promote effect on esophageal cancer cell proliferation. Taken together, our data identify a new role of miR-506 in esophageal cancer involving CREB1 suppression. PMID:26617801

    The aim of this study was to observe the association between the occurrence of esophageal cancer lesions and esophageal mucosa fold (white ridges), and further identify where is the initial origin of esophageal cancer lesions in the esophagus mucosa. This was a cohort study which recruited 551 subjects underwent endoscopic examination in a high risk area of esophageal cancer in Linxian, Henan Province in 1987. 339 subjects with esophageal white ridges, and with red area or erosion lesion at the surface of the white ridges, was studied as exposure group. Other 212 subjects whose esophagus had no white ridges and pathological diagnosis was negative, was studied as control group. The endpoint was occurrence of pathologically confirmed esophageal cancer. After a 15-year follow-up, the results were compared between two groups. Among the 551 subjects, there were 339 cases with esophageal mucosal white ridges in the exposure group. During the period of 15 year follow-up, the incidence of esophageal cancer was 11.8% (9/76) in 76 case with simple mucosal white ridges, 33.5% (88/263) in 263 subjects with white ridges and red area, or erosions on the surface of white ridge. While only 8.0% of subjects (17/212) developed esophageal cancer after the 15-year follow up in the control group. There was a significant difference between the two groups (P < 0.001). Esophageal mucosal white ridge, especially white ridge with red area or erosions is closely associated with subsequent esophageal cancer occurrence in the esophageal cancer high risk area in China. It is suggested that esophageal mucosa with white ridge may be the initial origin of esophageal cancer. Further investigations focused on this spot are required.

    Abnormal telomere length is widely reported in various human cancers, and it is considered to be an important hallmark of cancer. However, there is remarkably little consensus on the value of telomere length in the prognostic evaluation of esophageal cancers. Here, we attempted to determine the association of variable telomere length with clinical outcome of esophageal cancer patients. Using real-time quantitative PCR, we examined relative telomere lengths (RTL) in a cohort of esophageal cancer and normal esophageal tissues, and statistically investigated the association between RTL and clinical outcomes of esophageal cancer patients. The majority of esophageal cancers in this study had longer RTLs as compared to adjacent non-tumor tissues. Enhanced tumor RTL was associated with smoking habit, poor differentiation, advanced tumor stage, lymph node metastasis and cancer related death. In particular, a close relationship between longer RTL and poor survival was fully demonstrated by using cox regression and Kaplan-Maier survival curves. We found frequent telomere elongation in esophageal cancer tissues, and demonstrated longer RTL may be an independent poor prognostic factor for esophageal cancer patients.

    Background and Objectives: Lymph node metastases are the most important prognostic factor in patients with esophageal cancer. Histologic examination misses micrometastases in up to 20% of lymph nodes evaluated. In addition, non-invasive imaging modalities are not sensitive enough to detect small lymph nodes metastases. The objective of this study was to investigate the use of reverse transcriptase-polymerase chain reaction (RT-PCR) of messenger RNA (mRNA) for carcinoembryonic antigen (CEA) to increase the detection of micrometastases in lymph nodes from patients with esophageal cancer. Methods: RT-PCR of CEA mRNA was performed in lymph nodes from patients with malignant and benign esophageal disease. Each specimen was examined histopathologically and by RT-PCR and the results were compared. Results: Metastases were present in 29 of 60 (48%) lymph nodes sample by minimally invasive staging from 13 patients with esophageal cancer when examined histopathologically. RT-PCR identified nodal metastases in 46 of these 60 (77%) samples. RT-PCR detected CEA mRNA in all 29 histologically positive samples and in 17 histologically negative lymph nodes. All lymph nodes from patients with benign disease (n=15) were negative both histopathologically and by RT-PCR. The stage of two patients was reclassified based on the RT-PCR results, which identified lymph node spread undetected histopathologically. Both of these patients developed recurrent disease after resection of the primary tumor. Conclusions: RT-PCR is more sensitive than histologic examination in the detection of lymph node metastases in esophageal cancer and can lead to diagnosis of a more advanced stage in some patients. The combination of minimally invasive surgical techniques in combination with new molecular diagnostic techniques may improve our ability to stage cancer patients. PMID:10036123

    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.

    Several published studies have examined various self-expanding metal esophageal stents for use in the palliative treatment of esophageal or cardiac neoplasia, but few have compared different self-expanding metal stents. The aim of this study was to evaluate non-covered Wallstent and Ultraflex prostheses in the treatment of malignancies in the esophagus and the cardiac region. In a retrospective study, the effectiveness of non-covered Wallstents (46 patients) and Ultraflex stents (36 patients) was compared in the treatment of malignancies in the esophageal and cardiac regions. Reintervention procedures were necessary in 16 of the 46 Wallstent patients (six patients during an early phase) and in 22 of the 36 Ultraflex patients (13 during an early phase) (overall P = 0.022; early P = 0.018). The major complication in the Wallstent group was tumor ingrowth (12 of 35 complications), while in the Ultraflex group, it was incomplete deployment (18 of 49 complications). Incomplete stent deployment occurred more often in patients treated with Ultraflex (P = 0.01), and food impaction was more often observed in the Wallstent group (P = 0.001). In addition, in patients with Ultraflex stents, more complex reinterventions were necessary than those required with Wallstents (four vs. 13 complex reinterventions, P = 0.0046). Wallstents tended to improve dysphagia better than Ultraflex stents. Compared to Ultraflex stents, Wallstents have several significant short-term and long-term advantages in the palliative treatment of malignancy of the esophagus and cardia.

    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. PMID:22873795

    To address uncertainty of whether pathologic stage groupings after neoadjuvant therapy (ypTNM) for esophageal cancer share prognostic implications with pathologic groupings after esophagectomy alone (pTNM), we report data-simple descriptions of patient characteristics, cancer categories, and non-risk-adjusted survival-for pathologically staged cancers after neoadjuvant therapy from the Worldwide Esophageal Cancer Collaboration (WECC). Thirty-three institutions from six continents submitted data using variables with standard definitions: demographics, comorbidities, clinical cancer categories, and all-cause mortality from first management decision. Of 7,773 pathologically staged neoadjuvant patients, 2,045 had squamous cell carcinoma, 5,686 adenocarcinoma, 31 adenosquamous carcinoma, and 11 undifferentiated carcinoma. Patients were older (61 years) men (83%) with normal (40%) or overweight (35%) body mass index, 0-1 Eastern Cooperative Oncology Group performance status (96%), and a history of smoking (69%). Cancers were ypT0 (20%), ypT1 (13%), ypT2 (18%), ypT3 (44%), ypN0 (55%), ypM0 (94%), and G2-G3 (72%); most involved the distal esophagus (80%). Non-risk-adjusted survival for yp categories was unequally depressed, more for earlier categories than later, compared with equivalent categories from prior WECC data for esophagectomy-alone patients. Thus, survival of patients with ypT0-2N0M0 cancers was intermediate and similar regardless of ypT; survival for ypN+ cancers was poor. Because prognoses for ypTNM and pTNM categories are dissimilar, prognostication should be based on separate ypTNM categories and groupings. These data will be the basis for the 8th edition cancer staging manuals following risk adjustment for patient, cancer, and treatment characteristics and should direct 9th edition data collection. © 2016 International Society for Diseases of the Esophagus.

    Chromosomal aberration is an important genetic feature of malignant tumor cells. This study aimed to clarify whether BAC DNA could be used to identify chromosome region and arm alterations. For each chromosome region, five to ten 1 Mb BAC DNA clones were selected to construct mixed BAC DNA clones for the particular region. All of the mixed clones from regions which could cover the whole chromosome arm were then mixed to construct mixed BAC DNA clones for the arms. Mixed BAC DNA probes of arms and regions were labeled by degenerate oligonucleotide primed PCR (DOP-PCR) and Nick translation techniques, respectively. The specificities of these probes were validated by fluorescence in situ hybridization (FISH) on the metaphase chromosomes of normal human peripheral blood lymphocytes. FISH with arm-specific mixed BAC DNA probes showed that chromosomal rearrangements and involved chromosome arms were confirmed in several esophageal cancer cells. By using region-specific mixed probes, the breakpoint on 1q from the derivative chromosome t(1q;7q) was identified in 1q32-q41 in esophageal KYSE140 cells. In conclusion, we established an effective labeling method for 1 Mb BAC DNA mixed clone probes, and chromosome arm and region rearrangements could be identified in several esophageal cancer cells by using these probes. Our study provides a more precise method for identification of chromosomal aberration by M-FISH, and the established method may also be applied to the karyotype analysis of hematological malignancies and prenatal diagnosis.

    To review the prevalence and clinical importance of esophageal rupture during balloon dilation for treatment of esophageal stricture. Fluoroscopically guided esophageal balloon dilation was performed within 9 years in 96 consecutive patients with esophageal strictures. Esophageal rupture was classified into three types: type 1 was intramural; type 2, transmural; and type 3, transmural with mediastinal leakage. Each patient underwent one to seven procedures, for a total of 191 procedures. Esophageal rupture occurred in 20 patients (21%). Type 1 esophageal rupture occurred in eight patients, type 2 in 11, and type 3 in one. All esophageal ruptures were detected immediately after the procedure. Sixteen patients were treated with fasting, parenteral alimentation, and antibiotics; two were treated surgically; and two were treated with stent placement. No treatment-related deaths occurred. The overall prevalence of esophageal rupture was 21%. A substantial number of patients who developed type 1 rupture had associated clinical symptoms, such as pain and fever, but responded to conservative management and are thus included as having complications of esophageal balloon dilation.

    Inhibition of immune checkpoint proteins (checkpoints) has become a promising anti-esophageal cancer strategy. We here tested expressions of immune checkpoints in human esophageal cancers. Our results showed the expressions of many immune checkpoints, including CD28, CD27, CD137L, programmed death 1 (PD-1), T cell immunoglobulin mucin-3 (TIM-3), T cell Ig and ITIM domain (TIGIT), CD160, cytotoxic T lymphocyte antigen 4 (CTLA-4), CD200, CD137 and CD158, were dysregulated in peripheral T cells of esophageal cancer patients. Further, the expressions of PD-1, TIM-3 and TIGIT were upregulated in tumor infiltrating lymphocytes (TILs), which might be associated with TILs exhaustion. Meanwhile, the expressions of PD-1 and TIM-3 on CD4+ T cells were closely associated with clinic pathological features of esophageal cancer patients. These results indicate that co-inhibitory receptors PD-1, TIM-3 and TIGIT may be potential therapeutic oncotargets for esophageal cancer. PMID:27577071

    Healthcare research is a neglected discipline in Pakistan and research related to esophageal cancer (ranks 9th in Pakistani males and 5th in females) is no exception in this regard. Particularly, there are no data available to delineate the overall status of esophageal cancer epidemiological studies in Pakistan. This study describes the first ever effort to make a systematic quantification, in an attempt to provide a roadmap to all stakeholders for designing appropriate epidemiological, diagnostic and therapeutic strategies. International (PubMed, ISI Web of Knowledge) and local (PakMedinet) scientific databases as well as Google search engine were searched using specified keywords to extract relevant publication. Well defined inclusion criteria were implemented to select publications for final analyses. All data were recorded by at least 3 authors and consensus data were entered into and analyzed for descriptive statistics (such as frequencies, percentages and annual growth rates) using Microsoft Excel and SPSS software. A total of 79 publications fulfilled the inclusion criteria including 20 publications for which full texts were not available. Of the 79 publications, 59 (74.6%) were original/research publications, 5 (6.3%) were case reports, 4 (5.1%) were research communications, 2 (2.5%) were review articles, 1 was (1.2%) correspondence and 8 (10.1%) were un defined categories. Only 13 <20%) cities of Pakistan contributed towards the 79 publications. On average, only 1.9 relevant publications/year were published from 1976 (year of first publication) to the present. Alarmingly, a decline in the annual growth at 4.1% was recorded in the last six years. Esophageal cancer research is largely unfathomed in Pakistan. Urgent/dramatic steps are required by all concerned to address this common (and under reported) cancer of Pakistan.

    Esophageal cancer (EC) is one of the most common malignancies with poor prognosis. Metabolomics has been shown to be a powerful approach to discover the potential biomarkers for cancer diagnosis and prognosis. The goal of this study is to screen potential biomarkers for early diagnosis and prognosis. In this study, 40 tissue samples and the corresponding control samples from the same esophageal squamous cell carcinoma (ESCC) patients were analyzed by liquid chromatography-mass spectrometry (LC-MS)-based metabolomics. 20 potential diagnostic biomarkers were selected. Moreover, 9 metabolites were found to be closely correlated with the pathological feature such as local invasion, lymphatic metastasis and postoperative survival time. Glutamate was correlated with local invasion of tumor, and oleic acid, LysoPC(15:0), uracil, inosine and choline were closely related with the lymphatic metastasis, while glutamine, kynurenine, serine and uracil were related with postoperative survival time. The results indicated that the potential biomarkers discovered by metabolomics could reflect the metabolic characterization of ESCC, and offers a novel approach for early diagnosis, assessment and prognosis of the disease.

    Purpose: Severe (Radiation Therapy Oncology Group [RTOG] grade 3 or greater) esophagitis generally occurs in 15% to 25% of non–small cell lung cancer (NSCLC) patients undergoing concurrent chemotherapy and radiation therapy (CCRT), which may result in treatment breaks that compromise local tumor control and pose a barrier to dose escalation. Here, we report a novel contralateral esophagus-sparing technique (CEST) that uses intensity modulated radiation therapy (IMRT) to reduce the incidence of severe esophagitis. Methods and Materials: We reviewed consecutive patients with thoracic malignancies undergoing curative CCRT in whom CEST was used. The esophageal wall contralateral (CE) to the tumor was contoured as an avoidance structure, and IMRT was used to guide a rapid dose falloff gradient beyond the target volume in close proximity to the esophagus. Esophagitis was recorded based on the RTOG acute toxicity grading system. Results: We identified 20 consecutive patients treated with CCRT of at least 63 Gy in whom there was gross tumor within 1 cm of the esophagus. The median radiation dose was 70.2 Gy (range, 63-72.15 Gy). In all patients, ≥99% of the planning and internal target volumes was covered by ≥90% and 100% of prescription dose, respectively. Strikingly, no patient experienced grade ≥3 esophagitis (95% confidence limits, 0%-16%) despite the high total doses delivered. The median maximum dose, V45, and V55 of the CE were 60.7 Gy, 2.1 cc, and 0.4 cc, respectively, indicating effective esophagus cross-section sparing by CEST. Conclusion: We report a simple yet effective method to avoid exposing the entire esophagus cross-section to high doses. By using proposed CE dose constraints of V45 <2.5 cc and V55 <0.5 cc, CEST may improve the esophagus toxicity profile in thoracic cancer patients receiving CCRT even at doses above the standard 60- to 63-Gy levels. Prospective testing of CEST is warranted.

    Metastatic pancreatic cancer (MPC) is one of the most aggressive malignancies, known to be chemo-resistant and have been recently considered resistant to some targeted therapies (TT). Erlotinib combined to gemcitabine is the only targeted therapy that showed an overall survival benefit in MPC. New targets and therapeutic approaches, based on new-TT, are actually being evaluated in MPC going from immunotherapy, epigenetics, tumor suppressor gene and oncogenes to stromal matrix regulators. We aim in this paper to present the major causes rendering MPC an untargetable malignancy and to focus on the new therapeutic modalities based on TT in MPC. PMID:26989465

    The most distinctive feature of FDG-PET cancer screening program is the ability to find various kinds of malignant neoplasms in a single test. The aim of this survey is to clarify the range and frequency of various malignant neoplasms detected by FDG-PET cancer screening performed in Japan. "FDG-PET cancer screening" was defined as FDG-PET or positron emission tomography and computed tomography (PET/CT) scan with or without other tests performed for cancer screening of healthy subjects. This survey was based on a questionnaire regarding FDG-PET cancer screening. We analyzed the situation of 9 less frequently found malignant neoplasms including malignant lymphoma, malignancy of head and neck, esophagus, hepatobiliary and gallbladder, pancreas, kidney, cervical and uterine, ovary, and bladder. The detailed information of subjects with the suspected 9 kinds of malignant neoplasms mentioned above in the FDG-PET cancer screening program was studied in a total of 1,219 cases from 212 facilities. A statistical significance between PET/CT and PET was found in relative sensitivity and PPV for renal cell cancer. Malignant lymphoma was frequently of indolent type, suspected head and neck cancers had many false-positive results, and pancreatic cancer detected in this program was often in the advanced stage even in asymptomatic subjects. The recommendation of combined screening modality to PET or PET/CT was as follows: gastric endoscopy for assessing early esophageal cancer; abdominal ultrasound for screening hepatobiliary and gallbladder cancer; pelvic magnetic resonance imaging for assessing gynecological and pelvic cancers; and the CA125 blood test for screening ovarian cancer. Delayed image was helpful depending on the type of suspected malignant neoplasm. We analyzed various types of malignant neoplasms detected by the FDG-PET cancer screening program and presented recommended combination of examinations to cover FDG-PET and PET/CT.

  13. Engineering Stent Based Delivery System for Esophageal Cancer Using Docetaxel.

    2015-07-06

    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.

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

    PubMed

    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.

  15. The prognostic effect of ethnicity for gastric and esophageal cancer: the population-based experience in British Columbia, Canada

    PubMed Central

    2011-01-01

    Background Gastric and esophageal cancers are among the most lethal human malignancies. Their epidemiology is geographically diverse. This study compares the survival of gastric and esophageal cancer patients among several ethnic groups including Chinese, South Asians, Iranians and Others in British Columbia (BC), Canada. Methods Data were obtained from the population-based BC Cancer Registry for patients diagnosed with invasive esophageal and gastric cancer between 1984 and 2006. The ethnicity of patients was estimated according to their names and categorized as Chinese, South Asian, Iranian or Other. Cox proportional hazards regression analysis was used to estimate the effect of ethnicity adjusted for patient sex and age, disease histology, tumor location, disease stage and treatment. Results The survival of gastric cancer patients was significantly different among ethnic groups. Chinese patients showed better survival compared to others in univariate and multivariate analysis. The survival of esophageal cancer patients was significantly different among ethnic groups when the data was analyzed by a univariate test (p = 0.029), but not in the Cox multivariate model adjusted for other patient and prognostic factors. Conclusions Ethnicity may represent underlying genetic factors. Such factors could influence host-tumor interactions by altering the tumor's etiology and therefore its chance of spreading. Alternatively, genetic factors may determine response to treatments. Finally, ethnicity may represent non-genetic factors that affect survival. Differences in survival by ethnicity support the importance of ethnicity as a prognostic factor, and may provide clues for the future identification of genetic or lifestyle factors that underlie these observations.

    2016-01-01

    Introduction Intramural esophageal tumors (IET) are located between unchanged mucous membrane and muscularis mucosae. They can be both benign and malignant. Aim To evaluate diagnostic and therapeutic difficulties of IET. Material and methods During the years 2010–2015, 11 patients with IET were treated in our clinic. Diagnostics included gastroscopy, computed tomography of the chest, endoscopic ultrasound (EUS) guided fine needle biopsy, and positron emission tomography (PET) of the esophagus in cases with no histopathological confirmation. Results Based on the conducted analysis we diagnosed 1 case of gastrointestinal stromal tumor (GIST), 1 case of adenocarcinoma, and 2 cases of esophageal cysts. In another 7 cases radiological images resembled leiomyoma but with no histopathological confirmation. Esophagectomy was performed in 2 cases of malignant tumors and 1 case of a large benign tumor. In other cases surgical enucleation of tumors was performed. Postoperatively we diagnosed 6 cases of leiomyoma, 1 case of schwannoma, 2 esophageal cysts, 1 case of GIST and 1 of esophageal cancer. Conclusions Intramural esophageal tumors is a very diverse group of tumors, both malignant and benign. In every case of IET we should seek histopathological conformation. Treatment of IET depends on localization, size and histopathological type of lesion. PMID:28096828

    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.

    AIM: To evaluate if differences exist between self-expanding esophageal metal stents (SEMS) and self-expanding esophageal plastic stents (SEPS) when used for benign or malignant esophageal disorders with regard to safety, efficacy, clinical outcomes, placement ease and cost. METHODS: A retrospective analysis was performed to evaluate outcome in patients having SEPS/SEMS placed for malignant or benign esophageal conditions from January 2005 to April 2012. Inclusion criteria was completed SEMS/SEPS placement. Outcomes assessed included technical success of and time required for stent placement, procedure-related complications, need for repeat intervention, hospital stay, mortality and costs. RESULTS: Forty-three patients underwent stent placement for either benign/malignant esophageal disease during the study period. Thirty patients had SEMS (25 male, mean age 59.6 years old) and 13 patients had SEPS (10 male, mean age 61.7 years old). Placement outcome as well as complication rate (SEPS 23.1%, SEMS 25.2%) and in-hospital mortality (SEPS 7.7%, SEMS 6.7%) after placement did not differ between stent types. Migration was the most frequent complication reported occurring equally between types (SEPS 66.7%, SEMS 57.1%). SEPS was less costly than SEMS, decreasing institutional cost by $255/stent. CONCLUSION: SEPS and SEMS have similar outcomes when used for benign or malignant esophageal conditions. However, SEPS use results in decreased costs without impacting care. PMID:27076872

    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

    Our aim is to describe the association between colorectal cancer (CRC) and humoral hypercalcemia of malignancy (HHM). Causes of hypercalcemia of malignancy include parathyroid hormone-related peptide (PTHrP) secretion, local osteolysis, calcitriol production and ectopic parathyroid hormone (PTH) secretion. Hypercalcemia of malignancy in patients with CRCs is a rare scenario. A patient with anal squamous cell carcinoma was admitted with hypercalcemia, suppressed PTH and hypophosphatemia. He was found to have metastatic anal squamous cell carcinoma to the liver. Further evaluation revealed elevated PTHrP and 1,25-dihydroxyvitamin D and low 25-hydroxyvitamin D. Over a 5-month course, the hypercalcemia responded poorly to bisphosphonates, transiently to prednisone, but showed marked improvement with chemotherapy. A review of English language publications in Pubmed and a reference search of retrieved articles revealed 29 cases of CRC causing PTHrP-mediated hypercalcemia. Most patients were middle-aged men (mean ± SD: 56.7 ± 13.4 years), with advanced metastatic cancer (85% with hepatic metastasis) and severe hypercalcemia (mean ± SD: 15.6 ± 1.9 mg/dL, 62% with Ca > 14). This condition is associated with high mortality (79%) and short survival (median 54.5 days, CI: 21 - 168). Despite being uncommon, HHM (PTHrP-mediated) should be considered in patients with metastatic CRC presenting with hypercalcemia. Clinicians should be aware that combined etiologies may be present, particularly in cases of resistant hypercalcemia. Treatment of the underlying malignancy is essential for calcium control.

  2. Esophageal cancer screening in achalasia: is there a consensus?

    2015-04-01

    Achalasia is an important but relatively uncommon disorder. While highly effective therapeutic options exist, esophageal cancer remains a long-term potential complication. The risk of esophageal cancer in achalasia remains unclear, with current guidelines recommending against routine endoscopic screening. However, given limited data and conflicting opinion, it is unknown whether consensus regarding screening practices in achalasia among experts exists. A 10-question survey to assess screening practices in achalasia was created and distributed to 28 experts in the area of achalasia. Experts were identified based on publications and meeting presentations in the field. Survey responses were received from 17 of 28 (61%) experts. Wide geographic distribution was seen among respondents, with eight (47%) from Europe or Australia, seven (41%) from the United States, and two (12%) from Asia. Screening for esophageal cancer was inconsistent, with nine (53%) experts endorsing the practice and eight (47%) not. Screening practices did not differ among geographic regions. No consensus regarding the risk for esophageal cancer in achalasia was seen, with three experts reporting no increased risk compared with the general population, eight experts a lifetime risk of 0.1-0.5%, three experts a 0.5-1% risk, two experts a 1-2% risk, and one expert a 3-5% risk. However, these differences in perception of risk did not influence screening practices. Upper endoscopy was utilized among all experts who endorsed screening. However, practices still varied with screening commencing at or within 1 year of diagnosis in two practices compared with 5 and 10 years in three respective practices each. Surveillance intervals also varied, performed every 2 years in four practices, every 3 years in four practices, and every 5 years in one practice. Practice variation in the management of achalasia itself was also seen, with initial treatment with Heller myotomy endorsed by eight experts, pneumatic

    There is scant experience with robot-assisted esophagectomy in cases of esophageal and gastro-esophageal junction cancer. Our aim is to report our current experience. Observational cohort study of the first 32 patients who underwent minimally invasive esophagectomy for esophageal cancer from September 2011 to June 2014. The gastric tube was created laparoscopically. In the thoracic field, a robot-assisted thoracoscopic approach was performed in the prone position with intrathoracic robotic hand-sewn anastomosis. Patient and tumour characteristics, surgical technique, short-term outcomes (morbidity and mortality) and oncological results (radicality and number of removed nodes) were evaluated. Thirty-two patients, with a mean age of 58 years (34-74) were treated by a totally minimally invasive esophagectomy: robotic laparoscopy and thoracoscopy (11 McKeown and 21 Ivor-Lewis). Twenty-nine received neoadjuvant chemoradiotherapy. There were no conversions to open surgery. Console time was 218minutes (190-285). Blood loss was 170ml (40-255). One patient died from cardiac disease. Nine patients had a major complication (Dindo-Clavien grade II or higher). There was no case of respiratory complication or recurrent laryngeal nerve palsy. Five patients had intrathoracic fistula, 4 radiological and one clinical. Three had chylothorax, 2 cervical fistula and one gastric tube necrosis. The median hospital stay was 12 days (8-50). All the resections were R0 and the median of removed lymph nodes was 16 (2-23). Our results suggest that minimally invasive esophagectomy with robot-assisted thoracoscopy is safe and achieves oncological standards. Copyright © 2014 AEC. Publicado por Elsevier España, S.L.U.

    We conducted a systematic review and meta-analysis of meat intake and esophageal cancer risk, with subgroup analyses based on meat type and histological type of cancer. The purpose of this study was to investigate the association between meat intake and risk of esophageal cancer. We searched MEDLINE, EMBASE and Cochrane Library (April 2013) for cohort and case-control studies that assessed meat intake and esophageal cancer risk. Random-effect or fixed-effect models were used to pool relative risks (RRs) from individual studies with heterogeneity and publication bias analyses carried out. Seven cohort and 28 case-control studies were included. The summary RRs for esophageal cancer for the highest versus lowest consumption categories were 1.19 (95 % confidence interval [CI] 0.98-1.46) for total meat, 1.55 (95 % CI 1.22-1.96) for red meat, 1.33 (95 % CI 1.04-1.69) for processed meat, 0.72 (95 % CI 0.60-0.86) for white meat, 0.83 (95 % CI 0.72-0.96) for poultry, and 0.95 (95 % CI 0.76-1.19) for fish. When striated by histological subtype, positive associations were seen among esophageal squamous cell carcinoma and red meat, white meat and poultry, and esophageal adenocarcinoma with total meat and processed meat. Meat consumption is associated with esophageal cancer risk, which depends on meat type and histological type of esophageal cancer. High intake of red meat and low intake of poultry are associated with an increased risk of esophageal squamous cell carcinoma. High meat intake, especially processed meat, is likely to increase esophageal adenocarcinoma risk. And fish consumption may not be associated with incidence of esophageal cancer.

    External beam radiotherapy (EBRT) treats gross tumors and local microscopic diseases. Radionuclide therapy by radioisotopes can eradicate tumors systemically. Rhenium 188 (188Re)-liposome, a nanoparticle undergoing clinical trials, emits gamma rays for imaging validation and beta rays for therapy, with biodistribution profiles preferential to tumors. We designed a combinatory treatment and examined its effects on human esophageal cancer xenografts, a malignancy with potential treatment resistance and poor prognosis. Human esophageal cancer cell lines BE-3 (adenocarcinoma) and CE81T/VGH (squamous cell carcinoma) were implanted and compared. The radiochemical purity of 188Re-liposome exceeded 95%. Molecular imaging by NanoSPECT/CT showed that BE-3, but not CE81T/VGH, xenografts could uptake the 188Re-liposome. The combination of EBRT and 188Re-liposome inhibited tumor regrowth greater than each treatment alone, as the tumor growth inhibition rate was 30% with EBRT, 25% with 188Re-liposome, and 53% with the combination treatment at 21 days postinjection. Combinatory treatment had no additive adverse effects and significant biological toxicities on white blood cell counts, body weight, or liver and renal functions. EBRT significantly enhanced the excretion of 188Re-liposome into feces and urine. In conclusion, the combination of EBRT with 188Re-liposome might be a potential treatment modality for esophageal cancer. PMID:26056445

    Esophageal cancer is one of the least studied and deadliest cancers worldwide with a poor prognosis due to limited options for treatment. Chemotherapy agents such as the microtubule-targeting compounds are the mainstay of palliation for advanced esophageal cancer treatment. However, the toxicity and side effects of tubulin-binding agents (TBAs) have promoted the development of novel, more potent but less toxic TBAs. Herein, we identified 2-[4-(3,4-dimethoxyphenyl)-3-methyl-1H-pyrazol-5-yl]-5-[(2-methylprop-2-en-1-yl)oxy] phenol (PPMP) as a novel TBA for esophageal cancer treatment. PPMP markedly inhibited tubulin polymerization, and decreased viability and anchorage-independent growth of esophageal cancer cell lines, effects that were accompanied by G2/M arrest and apoptosis. Importantly, we produced patient-derived esophageal cancer xenografts to evaluate the therapeutic effect of PPMP in a setting that best mimics the clinical context in patients with esophageal cancer. Overall, we identified PPMP as a novel microtubule-destabilizing compound and as a new therapeutic agent against esophageal carcinoma. PMID:27129160

    About 90% of esophageal cancers worldwide are Squamous Cell Carcinomas (SCC), mostly occurring in defined high-incidence areas of low and middle-resource countries. Historically, the highest incidences are reported in regions of Central Asia. One such region is Kashmir Valley in Northern India. In this review, we summarize a large body of epidemiological, toxicological and observational information on occurrence, dietary patterns and lifestyles to discuss factors that may be involved in the etiology of SCC in Kashmir Valley. To date, no single factor can be identified as the main cause of the excess incidence of SCC as compared to other regions of India. Three main components emerge as important factors: a societal component with poor, rural lifestyle and general deprivation, status in particular in vitamins and oligoelements; a lifestyle component with the use of copper utensil in cooking, the consumption of spicy, deep fried foodstuffs, and the drinking of hot salty tea; and an environmental component with exposure to high levels of dietary nitrosamines from diverse sources. Overall, these three components are similar to the general pattern of factors that have been involved in causing SCC in other high-incidence area in the so-called “esophageal cancer belt”, namely in central China (Cixian, Lixian) and in Northern Iran (Golestan). Further comparative studies between these regions are needed to identify the contributions of these various components. PMID:21475514

    MicroRNAs are an abundant class of noncoding RNAs (approx. 18- 25 nucleotides in length) that suppress translation through binding to their target mRNAs, eventually leading to mRNAs degradation. Sequences of these endogenous RNA molecules are highly conserved, even among unrelated species, indicating their involvement in basic bio-logical processes, such as development, differentiation, proliferation or apoptosis. MiRNAs also participate on regulation of cancer stem cell functioning, immune system and malignant transformation. This review provides a comprehensive overview of miRNAs functions in esophageal cancer, their roles in key pathogenetic pathways and disease development, as well as their potential usage in clinical routine as bio-markers improving dia-gnosis, prognosis and prediction of therapeutic response. Through regulation of signaling pathways important in malignant transformation, miRNAs present also promising therapeutic targets.

    This study aimed to evaluate the receptor activator of nuclear factor-κB (RANK) expression statuses of esophageal squamous cell carcinoma (ESCC) patients, high-grade intraepithelial neoplasia (HGIN), low-grade intraepithelial neoplasia (LGIN), and normal esophageal tissues (NETs) in Chinese Han and Kazakh ethnic, as well as the correlation of RANK expression with clinicopathological characteristics. RANK immunohistochemical analysis was conducted to investigate the expression of RANK in 113 ESCC, 36 HGIN, 63 LGIN, and 98 NETs from Han ethnic patients and in 196 ESCC and 76 NETs from Kazakh ethnic patients. The associations of RANK expression with ethnic and clinicopathological characteristics were examined using χ2-test. Upregulated RANK expression was detected in both Han and Kazakh ethnic ESCC tissues, compared with NETs (P = 1.11×10-5, 0.001, respectively). RANK expression was significantly increased during malignant transformation from normal epithelium into LGIN (P = 2.84×10-7) and HGIN (P = 7.83×10-6) tissues in Han ethnic patients. The increased expression of RANK also correlated with lymph node metastasis in Kazakh ethnic ESCC patients (P = 0.019). By contrast, no significant correlation existed between RANK expression and clinicopathological characteristics of Han ethnic ESCC patients. Furthermore, Kaplan-Meier survival analysis showed that ESCC patients with higher expression of RANK protein had significantly worse prognosis than ESCC patients with low or no expression (P = 0.001). In conclusion, this study is the first to identify RANK overexpression as a novel esophageal cancer marker in both Kazakh and Han ethnic ESCC patients. The results support the association of RANK with ESCC across ethnicities. In summary, RANK could be a therapeutic target in ESCC patients. PMID:25973136

  11. Secondary malignant neoplasms in testicular cancer survivors.

    Testicular cancer is the most common cancer among men aged 15 to 40 years, and the incidence of testicular cancer is steadily increasing. Despite successful treatment outcomes and the rate of survival at 5 to 10 years being 95%, survivors can experience late effects of both their cancer and the treatment they received, including secondary malignant neoplasms (SMNs). We discuss the development of non-germ cell SMNs that develop after diagnosis and treatment of testicular cancer and their effect on mortality. Patients diagnosed with testicular cancer frequently choose postoperative surveillance if they are diagnosed with clinical stage I disease. These patients may experience an increased risk for developing SMNs following radiation exposure from diagnostic imaging. Similarly, radiotherapy for testicular cancer is associated with increased risks of developing both solid tumors and leukemia. Studies have reported that patients exposed to higher doses of radiation have an increased risk of developing SMNs when compared with patients who received lower doses of radiation. Patients treated with chemotherapy also experience an increased risk of developing SMNs following testicular cancer, though the risk following chemotherapy and radiation therapy combined is not well described. A large population-based study concluded that the rate ratios for both cancer-specific and all-cause mortality for SMNs among testicular cancer survivors were not significantly different from those of matched first cancers. Although it is known that patients who receive adjuvant chemotherapy or radiotherapy or who undergo routine diagnostic or follow-up imaging for a primary testicular cancer are at an increased risk for developing SMNs, the extent of this risk is largely unknown. It is critically important that research be conducted to determine this risk and its contributing factors as accurately as possible. Copyright © 2015 Elsevier Inc. All rights reserved.

    There are many controversies in lymphadenectomy for thoracic esophageal cancer, and whether 3-field lymphadenectomy or 2-field lymphadenectomy is better have still been in doubt. The aim of this article is to review the role of the lymph node dissection by introducing the merits and demerits in 3-field lymphadenectomy, and the development in lymphadenectomy’s selection, treatment and diagnosis. All the literatures related to esophageal lymphadenectomy and minimally invasive surgery (MIE) were searched in PubMed database and the cross references were added and reviewed to complete the reference list. Several researches elucidated that better overall survival (OS) in patients with esophageal cancer after 3-field lymphadenectomy had been reported worldwide, and 3-field lymphadenectomy is more suitable for treating esophageal cancer with cervical and/or upper mediastinal lymph nodes metastasis than 2-field lymphadenectomy regardless of the tumor’s histology and location. Many approaches based on the characteristics of esophageal cancer lymph node metastasis are taken to improve the accuracy of 3-field lymphadenectomy and decrease the postoperative morbidity and mortality, while every approach needs further studies to demonstrate its feasibility. The benefits of the recently rapid-developed techniques performed in treating esophageal cancer: the MIE and the robotic-assisted thoracoscopic esophagectomy are illuminated as well, and both of them are technically safe and feasible for esophageal cancer, whereas further evaluations are still necessary.

    To evaluate the long-term survival of multidisciplinary treatment based on thoracic surgery for cervical esophageal squamous cell carcinoma. The clinical characters and follow-up data of forty-one cervical esophageal cancer patients who accepted multidisciplinary treatment based on surgery with preservation of pharynx and larynx were retrospectively reviewed, and the long-term survival was compared with 480 non-cervical esophageal cancers who accepted surgery in the same period done by the same surgical team. There were 28 males and 13 females with a mean age of 62 years old. In the cervical esophageal cancer group, 30 patients accepted neoadjuvant chemotherapy, 25 patients accepted adjuvant chemotherapy, and 21 patients accepted both. Six patients received postoperative radiation. Four patients underwent exploratory surgery alone, and 37 cases underwent radical surgery and cervical anastomosis. One case died during the perioperative period. The 1-, 3-, 5- and 8-year survival rates were 96.8%, 52.6%, 35.1%, and 35.1% in the 36 patients with cervical esophageal cancer who underwent radical surgery, and were 85.0%, 54.3%, 45.0%, and 36.7% respectively in the 457 non-cervical esophageal cancer patients. There was no significant difference between the cervical group and non-cervical group(P=0.91). Cervical esophageal cancer should be treated in a multidisciplinary approach to obtain satisfactory long-term outcomes.

    BACKGROUND & AIMS Esophageal squamous cell cancer accounts for more than 90% of cases of esophageal cancers. Its pathogenesis involves chronic epithelial irritation, although the factors involved in the inflammatory process and the mechanisms of carcinogenesis are unknown. We sought to develop a mouse model of this cancer. METHODS We used the ED-L2 promoter of Epstein-Barr virus to overexpress the transcriptional regulator Krüppel-like factor 4 (Klf4) in esophageal epithelia of mice; we used mouse primary esophageal keratinocytes to examine the mechanisms by which KLF4 induces cytokine production. RESULTS KLF4 was an epithelial-specific mediator of inflammation; we developed a new mouse model of esophageal squamous dysplasia and inflammation-mediated squamous cell cancer. KLF4 activated a number of proinflammatory cytokines, including TNF-α, CXCL5, G-CSF and IL-1α, within keratinocytes in an NF-κB– dependent manner. KLF4 was not detected in proliferating or cancer cells, indicating a non-cell autonomous effect of KLF4 on proliferation and carcinogenesis. CONCLUSIONS KLF4 has distinct functions in carcinogenesis; upregulation of Klf4 specifically in esophageal epithelial cells induces inflammation. This mouse model might be used to determine the molecular mechanisms of esophageal squamous cell cancer and inflammation-mediated carcinogenesis. PMID:20816834

    The aim of this study was to investigate the expression of miR-21 in esophageal cancer and the impact of miR-21 on apoptosis, invasion, and the expression of target genes in esophageal cancer cells. Fluorescence quantitative polymerase chain reaction analysis was used to detect the expression of miR-21 in human esophageal tissues, adjacent tissues, and an esophageal cancer cell line (TE-13). The antisense miR-21 oligonucleotide was generated commercially using the solid-phase chemical synthesis method. Transient transfection was used to transfect esophageal cancer cells (TE-13 antisense and TE-13 control cells). Flow cytometry and Transwell cell assays were used to detect the apoptosis and invasion of esophageal cancer cells, respectively. The western blot method was used to detect the expression of PTEN, PDCD4, and K-ras proteins. These analyses determined that mir-21 expression significantly increased in esophageal cancer tissues and in TE-13 cells, and that this phenomenon was not associated with staging or lymph node metastasis. The apoptosis rate of TE-13 control cells was lower than that of antisense TE-13 cells indicating an enhanced invasive ability. In tissues adjacent to esophageal cancer and in TE-13 antisense cells, the expression of PTEN and PDCD4 was found to be higher than that in the control group, whereas the expression of K-ras showed the opposite pattern. Together, these results suggest that miR- 21 might be involved in the development and metastasis of esophageal cancer, through interaction with its PDCD4 and K-ras target genes.

    Incidence of esophageal cancer (EC) is rising more rapidly in the Western world than that of any other cancer. Despite advances in therapy, more than 50% of patients have incurable disease at the time of presentation. This precludes curative treatment and makes palliative treatment a more realistic option for most of these patients. Dysphagia is the predominant symptom in more than 70% of patients with EC and although several management options have been developed in recent years to palliate this symptom, the optimum management is not established. Self-expanding metal stents (SEMS) are a well-established palliation modality for dysphagia in such patients. Health-related quality of life (HRQoL) is becoming a major issue in the evaluation of any therapeutic or palliative intervention. To date, only a few published studies can be found on Medline examining HRQoL in patients with advanced EC treated with SEMS implantation. The aim of this study was to review the impact on HRQoL of SEMS implantation as palliative treatment in patients with EC. All Medline articles regarding HRQoL in patients with advanced EC, particularly those related to SEMS, were reviewed. In most studies, relief of dysphagia was the only aspect of HRQoL being measured and SEMS implantation was compared with other palliative treatments such as brachytherapy and laser therapy. SEMS insertion provides a swift palliation of dysphagia compared to brachytherapy and no evidence was found to suggest that stent implantation is different to laser treatment in terms of improving dysphagia, recurrent dysphagia and better HRQoL, although SEMS insertion has a better technical success rate and also reduces the number of repeat interventions.

    Esophageal cancer (EC) is one of the most aggressive malignancies of the upper aerodigestive tract. Over the past three decades, with advances in surgical techniques and treatment, the prognosis of esophageal cancer has only slowly improved. Thus identifying novel molecular targets and developing therapeutic agents are critical. Aurora kinases play a crucial role in mitosis and selective inhibitors might provide an effective therapeutic treatment for cancer. However, the role of Aurora kinases in EC is still inadequately studied. Here, we identified a novel compound, referred to as APIO-EE-9, which inhibits growth and colony formation and induces apoptosis of esophageal cancer cells. Using computer modeling, we found that APIO-EE-9 interacted with both Aurora A and B in the ATP-binding pocket. APIO-EE-9 inhibited both Aurora A and B kinase activities in a dose-dependent manner. Treatment with APIO-EE-9 substantially reduced the downstream Aurora kinase phosphorylation of histone H3 (Ser10), resulting in formation of multiple nuclei and centrosomes. Additionally, esophageal cancer cells expressing shAurora A or shAurora B kinase exhibited a dramatic reduction in proliferation and colony formation. Injection of these cells as xenografts in mice reduced tumor formation compared to wildtype cells. Importantly, APIO-EE-9 significantly decreased the size of esophageal patient-derived xenograft (PDX) tumors implanted in SCID mice. These results demonstrated that APIO-EE-9 is a specific Aurora kinase inhibitor that could be developed as a therapeutic agent against esophageal cancer.

    Early esophageal cancer is defined as a tumor invading the mucosa with or without lymph node or distant organ metastasis. In the current guidelines for early esophageal cancer, absolute indication for endoscopic resection include lesions limited to the epithelium or lamina propria mucosa not exceeding two-thirds of the circumference, and relative indications include lesions limited to the muscularis mucosa or the upper third of the submucosal layer and not accompanied by clinical evidence of lymph node metastasis. After endoscopic submucosal dissection for early esophageal cancer, locally recurrent cancer can occur, especially in the case of incomplete resection. Here, we report a rare case of a submucosal tumor-like recurrence after endoscopic resection of early esophageal cancer.

    New treatment strategies for prostate cancer have recently been developed, but multiple malignancies remain a major concern. The aim of this study was to evaluate the characteristics of multiple malignancies and to analyze the risk of secondary malignancies after radiotherapy for prostate cancer. From 2000 to 2011, 150 patients with prostate cancer were treated with curative radiotherapy in our department. Patient age range was 54-92 years (median, 70 years), and the follow-up period was 4-142 months (median, 48 months). The incidence of multiple primary cancers was compared with the estimated incidence. A total of 147 patients (98 %) survived more than 12 months (12-142 months; median, 48 months); 20/150 patients (13 %) died within 10 years. Cause of death was recurrent prostate cancer in 11 patients, other primary malignancies in 7 patients, and cardiovascular disease in 2 patients. Multiple primary cancers were present in 26 of 150 patients (17 %), including 16 subsequent malignancies (11 %) with latent periods of 13-83 months (median, 43 months). The subsequent non-prostate malignancies were lung cancer in 4 patients, urinary bladder or ureter cancer in 4, stomach cancer in 3, malignant lymphoma in 2, and other in 3. Analysis of the observed incidence of secondary malignancies compared with the estimated incidence in the general population revealed a higher incidence of ureter cancer and malignant lymphoma. Close attention should be paid to secondary malignancies after radiotherapy for prostate cancer, including malignancies occurring within 5 years, which could be attributable to radiotherapy.

    Our aim is to describe the association between colorectal cancer (CRC) and humoral hypercalcemia of malignancy (HHM). Causes of hypercalcemia of malignancy include parathyroid hormone-related peptide (PTHrP) secretion, local osteolysis, calcitriol production and ectopic parathyroid hormone (PTH) secretion. Hypercalcemia of malignancy in patients with CRCs is a rare scenario. A patient with anal squamous cell carcinoma was admitted with hypercalcemia, suppressed PTH and hypophosphatemia. He was found to have metastatic anal squamous cell carcinoma to the liver. Further evaluation revealed elevated PTHrP and 1,25-dihydroxyvitamin D and low 25-hydroxyvitamin D. Over a 5-month course, the hypercalcemia responded poorly to bisphosphonates, transiently to prednisone, but showed marked improvement with chemotherapy. A review of English language publications in Pubmed and a reference search of retrieved articles revealed 29 cases of CRC causing PTHrP-mediated hypercalcemia. Most patients were middle-aged men (mean ± SD: 56.7 ± 13.4 years), with advanced metastatic cancer (85% with hepatic metastasis) and severe hypercalcemia (mean ± SD: 15.6 ± 1.9 mg/dL, 62% with Ca > 14). This condition is associated with high mortality (79%) and short survival (median 54.5 days, CI: 21 - 168). Despite being uncommon, HHM (PTHrP-mediated) should be considered in patients with metastatic CRC presenting with hypercalcemia. Clinicians should be aware that combined etiologies may be present, particularly in cases of resistant hypercalcemia. Treatment of the underlying malignancy is essential for calcium control.

    Esophageal cancer, comprising squamous carcinoma and adenocarcinoma, is a leading cause of cancer-related death in the world. Notably, the incidence of esophageal adenocarcinoma has increased at an alarming rate in the Western world. Unfortunately, the standard first-line chemo-radiotherapeutic approaches are toxic and of limited efficacy in the treatment of a significant number of cancer patients. The molecular analysis of cancer cells has uncovered key genetic and epigenetic alterations underlying the development and progression of tumors. These discoveries have paved the way for the emergence of targeted therapy approaches. This review will highlight recent progress in the development of targeted therapies in esophageal cancer. This will include a review of drugs targeting receptor tyrosine kinases and other kinases in esophageal cancer. Additional studies will be required to develop a rational integration of these targeted agents with respect to histologic types of esophageal cancer and the optimal selection of cancer patients who would most likely benefit from targeted therapy. Identification of AURKA and AXL as key molecular players in esophageal tumorigenesis and drug resistance strongly justifies the evaluation of the available drugs against these targets in clinical trials.

    Esophageal cancer (EC) and gastric cancer (GC) constitute a major cause of cancer deaths worldwide. Recent improvements in both surgical techniques and adjuvant/neoadjuvant radiotherapy and chemotherapy approaches have increased the survival of patients with loco-regional disease. However, most of the patients with GC or EC have advanced disease either at diagnosis or at follow-up. Despite recent advances in the treatment of advanced disease, these patients still do poorly. An emerging understanding of the molecular pathways that characterize cell growth, cell cycle, apoptosis, angiogenesis and invasion has provided novel targets in cancer therapy. In this review we describe the current status of targeted therapies in the treatment of EC and GC. These therapeutic strategies include EGFR inhibitors, antiangiogenic agents, cell cycle inhibitors, apoptosis promoters and matrix metalloproteinases inhibitors. The emerging data from the clinical development of these compounds has provided novel opportunities in the treatment of EC and GC that will probably translate into efficacy advantage in the treatment of these common malignancies.

    The effectiveness of perioperative oral health care management to decrease the risk of postoperative pneumonia have been reported lately. Since 2014, we introduced perioperative oral health care management for lung cancer and esophageal cancer patients. We report current status and effectiveness of perioperative oral health care management for lung cancer and esophageal cancer patients. Every 100 cases of lung cancer and esophageal cancer patients treated by surgery were classified 2 group with or without perioperative oral health care management and compared about postoperative complications retrospectively. In the lung cancer patients, the group with oral health care management could prevent postoperative pneumonia significantly and had shorter length of hospital stay than the group without oral health care management. In the esophageal cancer patients, there was little occurrence of postoperative pneumonia without significant difference between both group with or without oral health care management. A large number of esophageal cancer patients received neo-adjuvant chemotherapy and some patients developed oral mucositis and received oral care treatment before surgery. Treatment for oral mucositis probably improved oral environment and affected prevention of postoperative pneumonia. Perioperative oral health care management can prevent postoperative pneumonia of lung cancer and esophageal cancer patients by improvement of oral hygiene.

    BACKGROUND Patterns of failure after neoadjuvant chemoradiotherapy and surgery for esophageal cancer are poorly defined. METHODS All patients in the current study were treated with trimodality therapy for nonmetastatic esophageal cancer from 1995 to 2009. Locoregional failure included lymph node failure (NF), anastomotic failure, or both. Abdominal paraaortic failure (PAF) was defined as disease recurrence at or below the superior mesenteric artery. RESULTS Among 155 patients, the primary tumor location was the upper/middle esophagus in 18%, the lower esophagus in 32%, and the gastroesophageal junction in 50% (adenocarcinoma in 79% and squamous cell carcinoma in 21%) of patients. Staging methods included endoscopic ultrasound (73%), computed tomography (46%), and positron emission tomography/computed tomography (54%). Approximately 40% of patients had American Joint Committee on Cancer stage II disease and 60% had stage III disease. The median follow-up was 1.3 years. The 2-year locoregional control, event-free survival, and overall survival rates were 86%, 36%, and 48%, respectively. The 2-year NF rate was 14%, the isolated NF rate was 3%, and the anastomotic failure rate was 6%. The 2-year PAF rate was 9% and the isolated PAF rate was 5%. PAF was found to be increased among patients with gastroesophageal junction tumors (12% vs 6%), especially for the subset with ≥2 clinically involved lymph nodes at the time of diagnosis (19% vs 4%). CONCLUSIONS Few patients experience isolated NF or PAF as their first disease recurrence. Therefore, it is unlikely that targeting additional regional lymph node basins with radiotherapy would significantly improve clinical outcomes. PMID:24711267

    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 1200 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. PMID:15237455

    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.

    Esophageal cancer is one of the most lethal solid malignancies. Mounting evidence demonstrates that cancer stem cells (CSCs) are able to cause tumor initiation, metastasis and responsible for chemotherapy and radiotherapy failures. As CSCs are thought to be the main reason of therapeutic failure, these cells must be effectively targeted to elicit long-lasting therapeutic responses. We aimed to enrich and identify the esophageal cancer cell subpopulation with stem-like properties and help to develop new target therapy strategies for CSCs. Here, we found esophageal cancer cells KYSE70 and TE1 could form spheres in ultra low attachment surface culture and be serially passaged. Sphere-forming cells could redifferentiate and acquire morphology comparable to parental cells, when return to adherent culture. The sphere-forming cells possessed the key criteria that define CSCs: persistent self-renewal, overexpression of stemness genes (SOX2, ALDH1A1 and KLF4), reduced expression of differentiation marker CK4, chemoresistance, strong invasion and enhanced tumorigenic potential. SB525334, transforming growth factor-beta 1(TGF-β1) inhibitor, significantly inhibited migration and invasion of sphere-forming stem-like cells and had no effect on sphere-forming ability. In conclusion, esophageal cancer sphere-forming cells from KYSE70 and TE1 cultured in ultra low attachment surface possess cancer stem cell properties, providing a model for CSCs targeted therapy. TGF-β1 promotes the migration and invasion of sphere-forming stem-like cells, which may guide future studies on therapeutic strategies targeting these cells. - Highlights: • Esophageal cancer sphere-forming cells possess cancer stem cell properties. • Sphere-forming cells enhance TGF-β1 pathway activity. • TGF-β 1 inhibitor suppresses the migration and invasion of sphere-forming cells.

    Several studies have suggested that a significant minority of esophageal cancers are missed at endoscopy The aim of this study was to estimate the proportion of esophageal cancers missed at endoscopy on a national level, and to investigate the relationship between miss rates and patient and tumor characteristics. This retrospective, population-based, cohort study identified patients diagnosed with esophageal cancer between April 2011 and March 2012 in England, using two linked databases (National Oesophago-Gastric Cancer Audit and Hospital Episode Statistics). The main outcome was the rate of previous endoscopy within 3 - 36 months of cancer diagnosis. This was calculated for the overall cohort and by patient characteristics, including tumor site and disease stage. A total of 6943 new cases of esophageal cancer were identified, of which 7.8 % (95 % confidence interval 7.1 - 8.4) had undergone endoscopy in the 3 - 36 months preceding diagnosis. Of patients with stage 0/1 cancers, 34.0 % had undergone endoscopy in the 3 - 36 months before diagnosis compared with 10.0 % of stage 2 cancers and 4.5 % of stage 3/4 cancers. Of patients with stage 0/1 cancers, 22.1 % were diagnosed after ≥ 3 endoscopies in the previous 3 years. Patients diagnosed with an upper esophageal lesion were more likely to have had an endoscopy in the previous 3 - 12 months (P = 0.040). The most common diagnosis at previous endoscopy was an esophageal ulcer (48.2 % of investigations). Esophageal cancer may be missed at endoscopy in up to 7.8 % of patients who are subsequently diagnosed with cancer. Endoscopists should make a detailed examination of the whole esophageal mucosa to avoid missing subtle early cancers and lesions in the proximal esophagus. Patients with an esophageal cancer may be misdiagnosed as having a benign esophageal ulcer. © Georg Thieme Verlag KG Stuttgart · New York.

    The purpose of this review is to highlight the importance of telomeres, the mechanisms implicated in their maintenance, and their role in the etiology as well as the treatment of human esophageal cancer. We will also discuss the role of telomeres in the maintenance and preservation of genomic integrity, the consequences of telomere dysfunction, and the various factors that may affect telomere health in esophageal tissue predisposing it to oncogenesis. There has been growing evidence that telomeres, which can be affected by various intrinsic and extrinsic factors, contribute to genomic instability, oncogenesis, as well as proliferation of cancer cells. Telomeres are the protective DNA-protein complexes at chromosome ends. Telomeric DNA undergoes progressive shortening with age leading to cellular senescence and/or apoptosis. If senescence/apoptosis is prevented as a consequence of specific genomic changes, continued proliferation leads to very short (ie, dysfunctional) telomeres that can potentially cause genomic instability, thus, increasing the risk for activation of telomere maintenance mechanisms and oncogenesis. Like many other cancers, esophageal cancer cells have short telomeres and elevated telomerase, the enzyme that maintains telomeres in most cancer cells. Homologous recombination, which is implicated in the alternate pathway of telomere elongation, is also elevated in Barrett's-associated esophageal adenocarcinoma. Evidence from our laboratory indicates that both telomerase and homologous recombination contribute to telomere maintenance, DNA repair, and the ongoing survival of esophageal cancer cells. This indicates that telomere maintenance mechanisms may potentially be targeted to make esophageal cancer cells static. The rate at which telomeres in healthy cells shorten is determined by a number of intrinsic and extrinsic factors, including those associated with lifestyle.

    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.

    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.

    Background and study aims Esophageal adenocarcinoma (EAC) has a dismal prognosis unless treated early or prevented at the precursor stage of Barrett’s esophagus-associated dysplasia. However, some patients with cancer or dysplastic Barrett’s esophagus (DBE) may not be captured by current screening and surveillance programs. Additional screening techniques are needed to determine who would benefit from endoscopic screening or surveillance. Partial wave spectroscopy (PWS) microscopy (also known as nanocytology) measures the disorder strength (Ld), a statistic that characterizes the spatial distribution of the intracellular mass at the nanoscale level and thus provides insights into the cell nanoscale architecture beyond that which is revealed by conventional microscopy. The aim of the present study was to compare the disorder strength measured by PWS in normal squamous epithelium in the proximal esophagus to determine whether nanoscale architectural differences are detectable in the field area of EAC and Barrett’s esophagus. Methods During endoscopy, proximal esophageal squamous cells were obtained by brushings and were fixed in alcohol and stained with standard hematoxylin and Cyto-Stain. The disorder strength of these sampled squamous cells was determined by PWS. Results A total of 75 patient samples were analyzed, 15 of which were pathologically confirmed as EAC, 13 were DBE, and 15 were non-dysplastic Barrett’s esophagus; 32 of the patients, most of whom had reflux symptoms, acted as controls. The mean disorder strength per patient in cytologically normal squamous cells in the proximal esophagus of patients with EAC was 1.79-times higher than that of controls (P<0.01). Patients with DBE also had a disorder strength 1.63-times higher than controls (P<0.01). Conclusion Intracellular nanoarchitectural changes were found in the proximal squamous epithelium in patients harboring distal EAC and DBE using PWS. Advances in this technology and the biological

    Biodegradable stents are reportedly effective for refractory benign esophageal strictures; however, little is known about their use in patients with refractory stricture after endoscopic submucosal dissection (ESD) or chemoradiotherapy (CRT) for esophageal cancer. This study aimed to evaluate the effectiveness of biodegradable stents for these patients. Patients with refractory benign esophageal stricture with a dysphagia score (DS) of 2 or worse and for whom the passage of a standard size endoscope was not possible were eligible. The primary endpoint was the proportion of those who improved their DSs (% DS improved) at 12 weeks after stent placement, and the secondary endpoints were the proportion of those who improved their DSs at 24 weeks, dysphagia-free survival (DFS), and adverse events. Eighteen patients (men:women, 15:3; median age, 72 years; range, 53-80) were enrolled. Twelve patients improved their DS at 12 weeks (% DS improved, 66.7%; 90% CI, 44.6%-84.4%). Also, 8 of 11 patients (72.7%) after esophagectomy, 4 of 6 patients (66.7%) after ESD, and 3 of 4 patients (75%) after CRT improved at 12 weeks. Three patients who were treated with esophagectomy maintained their DS improvement at 24 weeks (% DS improved, 16.7%; 95% CI, 3.6%-41.4%). The median DFS was 14.1 weeks (95% CI, 13.0-19.0). One patient who had ESD and CRT developed an esophagobronchial fistula 3 months after stent placement. Biodegradable stents are effective and tolerable for refractory benign esophageal strictures after treatment for esophageal cancer; however, long-term efficacy was limited, especially after ESD or CRT.

    Genetic variations or polymorphisms within genes of the nucleotide excision repair (NER) pathway alter DNA repair capacity. Reduced DNA repair (NER) capacity may result in tumors that are more susceptible to cisplatin chemotherapy, which functions by causing DNA damage. We investigated the potential predictive significance of functional NER single nucleotide polymorphisms in esophageal cancer patients treated with (n = 262) or without (n = 108) cisplatin. Four NER polymorphisms XPD Asp312Asn; XPD Lys751Gln, ERCC1 8092C/A, and ERCC1 codon 118C/T were each assessed in polymorphism-cisplatin treatment interactions for overall survival (OS), with progression-free survival (PFS) as a secondary endpoint. No associations with ERCC1 118 were found. Polymorphism-cisplatin interactions were highly significant in both OS (P = 0.002, P = 0.0001, and P < 0.0001) and PFS (P = 0.006, P = 0.008, and P = 0.0007) for XPD 312, XPD 751, and ERCC1 8092, respectively. In cisplatin-treated patients, variant alleles of XPD 312, XPD 751, and ERCC1 8092 were each associated with significantly improved OS (and PFS): adjusted hazard ratios of homozygous variants versus wild-type ranged from 0.22 [95% confidence interval (CI): 0.1-0.5] to 0.31 (95% CI: 0.1-0.7). In contrast, in patients who did not receive cisplatin, variant alleles of XPD 751 and ERCC1 8092 had significantly worse survival, with adjusted hazard ratios of homozygous variants ranging from 2.47 (95% CI: 1.1-5.5) to 3.73 (95% CI: 1.6-8.7). Haplotype analyses affirmed these results. DNA repair polymorphisms are associated with OS and PFS, and if validated may predict for benefit from cisplatin therapy in patients with esophageal cancer.

    Vascular endothelial growth factor (VEGF) promotes angiogenesis and vascular permeability. The VEGF gene is polymorphic. We investigated the prognostic significance of three VEGF single nucleotide polymorphisms (SNP) in esophageal cancer. Three hundred sixty-one patients were genotyped for three VEGF SNPs (-460T/C, 405G/C, and 936C/T) using DNA extracted from prospectively collected blood samples. The association of each individual SNP, and haplotypes of the three SNPs, on overall survival (OS) was investigated. The variant allele of 936C/T was associated with improved OS compared with the wild-type genotype (log-rank P < 0.001). This association remained significant for OS after adjustments for age, gender, performance status, and disease stage [VEGF 936C/T: adjusted hazard ratio (AHR), 0.70; 95% confidence interval (95% CI), 0.49-0.99; P = 0.04; VEGF 936T/T: AHR, 0.11; 95% CI, 0.02-0.82; P = 0.03]. No independent associations were found for VEGF -460T/C and VEGF 405G/C. The CGC haplotype of the three VEGF SNPs (-460T/C, 405G/C, and 936C/T) combined was associated with reduced OS compared with all other patients (CGC/CGC: AHR, 1.51; 95% CI, 1.00-2.30; P = 0.05). VEGF 936C/T, and a haplotype of 460T/C, 405G/C, and 936C/T combined, has potential prognostic significance in esophageal cancer.

    The incidence of esophageal cancer increases, with approximately 482,000 patients diagnosed with esophageal cancer each year. Despite the growing incidence of esophageal carcinoma, the extent of the lymphadenectomy is still under discussion. Lymph node status is an important prognostic parameter in esophageal cancer and an independent predictor of survival. Surgical strategy depends on the distribution pattern of nodal metastases but consensus on the extent of lymphadenectomy differs worldwide. For squamous cell cancer, Japanese surgeons have standardized the 2- or 3-field lymphadenectomy according to the location of the tumor. For adenocarcinoma, in the Western World accounting for 85% of all esophageal cancers, the type of lymphadenectomy to perform is not clear. Moreover, the use of neoadjuvant therapy may influence the mediastinal lymph nodes and the significance of the lymphadenectomy for survival. These aspects have challenged the traditional policy concerning lymphadenectomy, at least in the Western World. Furthermore, an extensive lymphadenectomy may improve survival but, on the other hand, may cause significant more morbidity. An overview of the literature on the extent of lymphadenectomy for esophageal cancer with respect to the supposed lymph node distribution patterns for squamous cell carcinoma and adenocarcinoma, the different lymph node classification systems, the commonly used surgical techniques and outcomes, and the proposal of observational cohort study to standardize the type of lymphadenectomy according to the type of tumor, location and use of neoadjuvant therapy will be provided.

    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 < 0.05). In the resting state, the functional connectivity is abnormal in the cerebral regions in the DMN of esophageal cancer patients with theory of mind deficits. The theory of mind deficits might have an important function in the pathogenesis of esophageal cancer.

    Aim: Current chemotherapy for esophageal cancer is conducted on the basis of empirical information from clinical trials, which fails to take into account the known heterogeneity of chemosensitivity between patients. This study was aimed to demonstrate the degree of heterogeneity of chemosensitivity in esophageal cancers. Methods: A total of 42 esophageal cancer specimens were collected. The heterogeneity of chemosensitivity in esophageal cancer specimens was examined using an ex vivo ATP-tumor chemosensitivity assay (ATP-TCA). Results: Thirty eight specimens produced evaluable results (90.5%). The most active single agent tested was nedaplatin, to which 28.9% of samples were sensitive. Combinations of chemotherapy agents exhibited much higher sensitivity: cisplatin+paclitaxel was sensitive in 16 of 38 (42.1%) of samples, while nedaplatin+paclitaxel was more effective, which was sensitive in 20 of 38 cases (52.6%). Conclusion: There was a marked heterogeneity of chemosensitivity in esophageal cancer. Chemosensitivity testing may provide a practical method for testing new regimens before clinical trials in esophageal cancer patients. PMID:22286916

    Purpose Esophageal cancer (EC) is an aggressive malignancy and often resistant to therapy. Overexpression of EGFR has been associated with poor prognosis of EC patients. However, clinical trials using EGFR inhibitors have not provided benefit for EC patients. Failure of EGFR inhibition may be due to crosstalk with other oncogenic pathways. Experimental Design In this study, expression of YAP1 and EGFR were examined in EAC resistant tumor tissues vs sensitive tissues by immunohistochemistry. Western blot, immunofluorescence, real-time PCR, promoter analysis, site-directed mutagenesis and in vitro and in vivo functional assays were performed to elucidate the YAP1 mediate EGFR expression and transcription and the relationship with chemoresistance in esophageal cancer. Results We demonstrate that Hippo pathway coactivator YAP1 can induce EGFR expression and transcription in multiple cell systems. Both YAP1 and EGFR are overexpressed in resistant EC tissues compared to sensitive EC tissues. Further, we found that YAP1 increases EGFR expression at the level of transcription requiring an intact TEAD binding site in the EGFR promoter. Most importantly, exogenous induction of YAP1 induces resistance to 5-FU and docetaxcel, while knockdown of YAP sensitizes EC cells to these cytotoxics. Verteporfin, a YAP1 inhibitor, effectively inhibits both YAP1 and EGFR expression and sensitizes cells to cytotoxics. Conclusions Our data provide evidence that YAP1 up-regulation of EGFR plays an important role in conferring therapy resistance in EC cells. Targeting YAP1-EGFR axis may be more efficacious than targeting EGFR alone in EC. PMID:25739674

    Esophageal cancer is one of the most commonly diagnosed malignant tumors in China. This study aimed to examine the temporal trend of esophageal cancer mortality rates during the period 1987-2009 in both rural and urban settings and to detect the effects of year of death and year of birth on the trends using joinpoint regression analysis and an age-period-cohort model. Age-standardized mortality rates were calculated by the direct method using the world population of 1960, and joinpoint regression was performed to obtain the annual percentage change (APC) in mortality rate. Poisson regression models were fitted to evaluate the period and cohort effects after adjusting for age. During the period 1987-2009, age-standardized mortality rates showed an overall significant decrease for rural females (APC=-2.3, 95% confidence interval [CI]: -3.3%, -1.2%), urban males (APC=-1.8, 95% CI: -2.6%, -1.0%) and urban females (APC=-3.7, 95% CI: -4.9%, -2.4%), but the decrease was not statistically significant for rural males (APC=-0.9, 95% CI: -2.0%, 0.3%). After adjusting for age and with the birth cohort of 1900-1904 or period 1987-1991 as reference, the relative risk of successive cohorts decreased steadily and that of more recent periods kept relatively stable. The decreasing birth cohort effect in the recent generations could correspond to increased adoption of healthy dietary habits and life-styles in the population.

    Gastroesophageal reflux disease (GERD) is highly prevalent in the Western world. Patients with GERD have a 10 fold increased risk to develop a Barrett's esophagus. Patients with Barrett's esophagus have a higher risk for an esophageal adenocarcinoma. Men have more severe reflux with a higher grade of inflammation and acid reflux. This seems to be the reason why men develop a Barrett's esophagus more frequently--the risk is approximately 2 to 3 fold and the risk for an esophageal adenocarcinoma is even 3 to 6 times higher. © Georg Thieme Verlag KG Stuttgart · New York.

    2001-07-15

    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.

    Clinical and dosimetric predictors of severe (grade 3 or greater) acute esophageal toxicity and subsequent esophageal dilation were explored in patients with limited-stage small cell lung cancer treated with accelerated hyperfractionated chemoradiation. A total of 130 patients were identified who were treated to 45 Gy in 1.5-Gy twice-daily fractions with concurrent platinum-based chemotherapy between 2000 and 2009. Data on clinical, disease-related, and treatment-related variables were collected. Patients with percutaneous endoscopic gastrostomy tube insertion or intravenous hydration because of poor oral intake were designated as having acute grade 3 esophagitis. Univariate and multivariate analyses that associated treatment characteristics with esophagitis were assessed via logistic regression, and optimal cut points were identified with recursive partitioning analysis. Twenty-five patients developed severe acute esophagitis, at a rate of 26% (18/69) in patients treated with earlier 3-dimensional conformal radiation therapy techniques and 11.5% (7/61) in patients treated with intensity modulated radiation therapy techniques and omission of elective nodal irradiation. The incidence of esophageal stricture was 6% overall (8 of 128 eligible) but 26% (6/23) among those who experienced prior grade 3 acute esophagitis and 2% (2/105) among those with acute esophagitis less than or equal to grade 2. Significant multivariate predictors of acute esophagitis were mean dose and volume of esophagus receiving at least 5% to 35% of the prescribed dose (V5 to V40). Patients with V5 ≥ 74% had a 44.4% risk of severe acute esophagitis (12/27) versus 12.6% (13/103) among those with V5 < 74%. V45 was the only dosimetric predictor for esophageal stricture, with 13.7% of patients in whom V45 was ≥37.5% requiring subsequent dilation. Modern radiation techniques are associated with a lower frequency of severe acute esophagitis than previous paradigms. The proportion of esophagus

    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.

    Aerobic glycolysis is one of the emerging hallmarks of cancer cells. In this study, we investigated the relationship between blocking mitochondrial pyruvate carrier (MPC) with MPC blocker UK5099 and the metabolic alteration as well as aggressive features of esophageal squamous carcinoma. It was found that blocking pyruvate transportation into mitochondria attenuated mitochondrial oxidative phosphorylation (OXPHOS) and triggered aerobic glycolysis, a feature of Warburg effect. In addition, the HIF-1α expression and ROS production were also activated upon UK5099 application. It was further revealed that the UK5099-treated cells became significantly more resistant to chemotherapy and radiotherapy, and the UK5099-treated tumor cells also exhibited stronger invasive capacity compared to the parental cells. In contrast to esophageal squamous epithelium cells, decreased MPC protein expression was observed in a series of 157 human squamous cell carcinomas, and low/negative MPC1 expression predicted an unfavorable clinical outcome. All these results together revealed the potential connection of altered MPC expression/activity with the Warburg metabolic reprogramming and tumor aggressiveness in cell lines and clinical samples. Collectively, our findings highlighted a therapeutic strategy targeting Warburg reprogramming of human esophageal squamous cell carcinomas. PMID:27911865

    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.

    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.

    With the increasing incidence of esophageal cancer, drug resistance is becoming a major obstacle to successful cancer therapy since chemotherapy is regarded as a curative approach to inhibit cancer cell proliferation. Despite the great progress in anticancer treatment achieved during the last decades, the mechanisms of multidrug resistance have not been completely elucidated. Recently, accumulating studies and pre-clinical reports highlighted the role of miRNAs in the drug resistance of esophageal cancer. Areas covered: In this review, we mainly summarized the current advances of miRNAs in esophageal cancer and the mechanisms underlying drug resistance. We also reviewed the potential role of miRNAs as biomarkers for predicting drug response and prognosis. Finally, we envisaged the future orientation and challenges in translating the existing knowledge of drug resistance related miRNAs into clinical applications. Expert commentary: Based on the current knowledge of certain miRNAs, we believe that miRNAs would be helpful to overcome the drug resistance and provide personalized treatment for patients with esophageal cancer. The aims of this study were to provide a comprehensive summary on the emerging role of miRNAs in the drug resistance of esophageal cancer and attract broad attention of more researchers on this field.

    AIM: To compare the tolerability of magnifying narrow band imaging endoscopy for esophageal cancer screening with that of lugol chromoendoscopy. METHODS: We prospectively enrolled and analyzed 51 patients who were at high risk for esophageal cancer. All patients were divided into two groups: a magnifying narrow band imaging group, and a lugol chromoendoscopy group, for comparison of adverse symptoms. Esophageal cancer screening was performed on withdrawal of the endoscope. The primary endpoint was a score on a visual analogue scale for heartburn after the examination. The secondary endpoints were scale scores for retrosternal pain and dyspnea after the examinations, change in vital signs, total procedure time, and esophageal observation time. RESULTS: The scores for heartburn and retrosternal pain in the magnifying narrow band imaging group were significantly better than those in the lugol chromoendoscopy group (P = 0.004, 0.024, respectively, ANOVA for repeated measures). The increase in heart rate after the procedure was significantly greater in the lugol chromoendoscopy group. There was no significant difference between the two groups with respect to other vital sign. The total procedure time and esophageal observation time in the magnifying narrow band imaging group were significantly shorter than those in the lugol chromoendoscopy group (450 ± 116 vs 565 ± 174, P = 0.004, 44 ± 26 vs 151 ± 72, P < 0.001, respectively). CONCLUSION: Magnifying narrow band imaging endoscopy reduced the adverse symptoms compared with lugol chromoendoscopy. Narrow band imaging endoscopy is useful and suitable for esophageal cancer screening periodically. PMID:25759551

    Colon interposition is an alternative solution for esophageal reconstruction if the stomach cannot be used. The study reviews current indications and results of coloplasty for cancer. Patients who underwent colon interposition for gastro-esophageal malignancy were included. Primary coloplasty was defined as upfront colon interposition. Salvage coloplasty was defined as colon interposition after primary reconstruction failure. Mortality, morbidity, function, and survival were evaluated. We included 28 patients (24 men, median age 61 years). Ten (36%) patients underwent primary coloplasty due to previous gastrectomy (n = 5), conduit gastric cancer (n = 2), extensive gastroesophageal involvement (n = 2), and gastric cancer recurrence (n = 1). Salvage coloplasty was performed in 18 (64%) patients for postoperative graft necrosis (n = 5) and intractable strictures (n = 3). Operative mortality, morbidity, and graft necrosis rates were 14% (4/28), 86% (24/28), and 14% (4/28), respectively; there were no significant differences between primary and salvage coloplasty. Survival rates at 1-, 3-, and 5 years were 81%, 51%, and 38%, respectively. Survival was decreased after primary coloplasty when compared to salvage coloplasty (P = 0.03). Nine patients experienced tumor recurrence (primary: n = 6, salvage: n = 3) after coloplasty and eight of them died. Colon interposition after esophagectomy is a useful but morbid endeavor. Colon interposition as salvage therapy is associated with improved survival compared to its use as primary esophageal replacement, and colon interposition in the latter cohort should be used with caution due to poor cancer-specific survival in this patient population. © 2015 Wiley Periodicals, Inc.

    Autophagy plays a key role in the maintenance of cellular homeostasis. In healthy cells, such a homeostatic activity constitutes a robust barrier against malignant transformation. Accordingly, many oncoproteins inhibit, and several oncosuppressor proteins promote, autophagy. Moreover, autophagy is required for optimal anticancer immunosurveillance. In neoplastic cells, however, autophagic responses constitute a means to cope with intracellular and environmental stress, thus favoring tumor progression. This implies that at least in some cases, oncogenesis proceeds along with a temporary inhibition of autophagy or a gain of molecular functions that antagonize its oncosuppressive activity. Here, we discuss the differential impact of autophagy on distinct phases of tumorigenesis and the implications of this concept for the use of autophagy modulators in cancer therapy. PMID:25712477

    We performed a two-stage molecular epidemiological study to explore DNA methylation profiles for potential biomarkers of esophageal squamous cell carcinoma (ESCC) in a Chinese population. Infinium Methylation 450K BeadChip was used to identify genes with differentially methylated CpG sites. Sixteen candidate genes were validated by sequencing 1160 CpG sites in their promoter regions using the Illumina MiSeq platform. When excluding sites with negative changes, 10 genes (BNIP3, BRCA1, CCND1, CDKN2A, HTATIP2, ITGAV, NFKB1, PIK3R1, PRDM16 and PTX3) showed significantly different methylation levels among cancer lesions, remote normal-appearing tissues, and healthy controls. PRDM16 had the highest diagnostic value with the AUC (95% CI) of 0.988 (0.965–1.000), followed by PIK3R1, with the AUC (95% CI) of 0.969 (0.928–1.000). In addition, the methylation status was higher in patients with advanced cancer stages. These results indicate that aberrant DNA methylation may be a potential biomarker for the diagnosis of ESCC.

    The most common pattern of esophageal cancer metastases (ECM) is to the lymph nodes, lung, liver, bones, adrenal glands, and brain. On the other hand, unexpected metastasis (UM) spread to uncommon sites has increasingly reported and consequently affected the pathway of diagnosis, staging, and management. Using the PubMed database, a systematic search of the following headings “Esophageal” and “Metastasis” or “Metastases” was performed, 10049 articles were identified, and the articles were included if they demonstrated unexpected ECM. 84% of cases were men with an average age of 60.7 years. EC was located in the lower third in 65%. Two-thirds of the UM originated from the lower esophagus, and the two major histological types were adenocarcinoma 40% and squamous cell carcinoma 60%. Metastases were disseminated toward five main anatomical sites: the head and neck (42%), thoracic (17%), abdomen and pelvis (25%), extremities (9%), and multiple skin and muscle metastases (7%). The EC metastases were found to be synchronous 42% and metachronous 58%, isolated in 53.5% and multiple in 46.5%. The overall survival rate was 10.2 months. Since distant metastases are responsible for most EC-related deaths, understanding of ECM dissemination patterns needs more extensive studies. These critical data are the cornerstone of optimal cancer approach and treatment. PMID:28659974

    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.

    Surface-enhanced Raman scattering (SERS) spectra of hemoglobin from 30 esophageal cancer patients and 30 healthy persons have been detected and analyzed. The results indicate that, there are more iron ions in low spin state and less in high for the hemoglobin of esophageal cancer patients than normal persons, which is consistent with the fact that it is easier to hemolyze for the blood of cancer patients. By using principal component analysis (PCA) and discriminate analysis, we can get a three-dimensional scatter plot of PC scores from the SERS spectra of healthy persons and cancer patients, from which the two groups can be discriminated. The total accuracy of this method is 90%, while the diagnostic specificity is 93.3% and sensitivity is 86.7%. Thus SERS spectra of hemoglobin analysis combined with PCA may be a new technique for the early diagnose of esophageal cancer.

    Shp2 (Src-homology 2 domain-containing phosphatase 2) was originally reported as an oncogene in kinds of solid tumors and hematologic malignancies. However, recent studies indicated that Shp2 may act as tumor suppressors in several tumor types. We investigated the function of Shp2 in esophageal squamous cell cancer (ESCC). The expression level of Shp2 was analyzed in tumor tissues in comparison with adjacent normal tissues of ESCC patients by immunohistochemistry and Western blot. Shp2 was knocked down by Short hairpin RNA to evaluate its function in ESCC cell lines. The relationship between Shp2 and p-Stat3 (signal transducer and activator of transcription 3) in human ESCC tissues was statistically examined. A significant low expression of Shp2 was found in ESCC tissues. Low expression of Shp2 was related to poorer overall survival in patients from The Cancer Genome Atlas (TCGA) dataset. Knockdown of Shp2 increased the growth of ESCC cell lines both in vivo and vitro. Activation of Stat3 (p-Stat3) was induced by Shp2 depletion. Expression of p-Stat3 was negatively correlated with Shp2 expression in ESCC tissues. Furthermore, knockdown of Shp2 attenuated cisplatin-sensitivity of ESCC cells. Shp2 might suppress the proliferation of ESCC by dephosphorylation of p-Stat3 and represents a novel research field for targeted therapy. PMID:28085101

    Dysregulation of c-Myc is one of the most common abnormalities in human malignancies, including esophageal cancer, one of the world's most lethal cancers. MicroRNA-26 family, including miR-26a and miR-26b, is transcriptionally suppressed by c-MYC. Our previous microarray data indicated a decreased-expression of miR-26 family in esophageal squamous cell carcinoma (ESCC). However, its roles in c-MYC pathway regulation and esophageal cancer tumorigenesis have yet not been elucidated. In this study, we expanded the detection of miR-26 expression in ESCC patients and found that the great majority of ESCC tissues showed an >50% reduction, even in the early-staged tumor. Furthermore, ectopic expression of miR-26a or miR-26b induced ESCC cell growth inhibition and G1 phase arrest. MYC binding protein (MYCBP) was identified as a direct target of miR-26. MiR-26 could dramatically decrease MYCBP mRNA and protein levels, as well as the expression of luciferase carrying MYCBP 3'-untranslated region. Moreover, knock-down of MYCBP mimicked the effect of miR-26. More importantly, miR-26 overexpression could downregulate a series of c-MYC target genes as MYCBP silence did. Taken together, these results indicate that miR-26 family can suppress esophageal cancer cell proliferation by inhibition of MYCBP, subsequently downregulate c-MYC pathway. Besides, we also found that reduction of miR-26 expression in ESCC was not due to DNA methylation. Hence, our study reveals a novel feedback loop for c-MYC pathway and implicates miR-26 as a potential target for prevention and treatment of esophageal cancer. Copyright © 2017 Elsevier B.V.

    Esophageal squamous cell carcinoma (ESCC) is one of the deadliest malignancies worldwide. Radiotherapy plays a critical role in the curative management of inoperable ESCC patients. However, radioresistance restricts the efficacy of radiotherapy for ESCC patients. The molecules involved in radioresistance remain largely unknown, and new approaches to sensitize cells to irradiation are in demand. Technical advances in analysis of mRNA and methylation have enabled the exploration of the etiology of diseases and have the potential to broaden our understanding of the molecular pathways of ESCC radioresistance. In this study, we constructed radioresistant TE-1 and Eca-109 cell lines (TE-1/R and Eca-109/R, respectively). The radioresistant cells showed an increased migration ability but reduced apoptosis and cisplatin sensitivity compared with their parent cells. mRNA and methylation profiling by microarray revealed 1192 preferentially expressed mRNAs and 8841 aberrantly methylated regions between TE-1/R and TE-1 cells. By integrating the mRNA and methylation profiles, we related the decreased expression of transcription factor Sall2 with a corresponding increase in its methylation in TE-1/R cells, indicating its involvement in radioresistance. Upregulation of Sall2 decreased the growth and migration advantage of radioresistant ESCC cells. Taken together, our present findings illustrate the mRNA and DNA methylation changes during the radioresistance of ESCC and the important role of Sall2 in esophageal cancer malignancy. PMID:28367244

    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

    Abstract Aortic pseudoaneurysm formation subsequent to concurrent chemoradiotherapy (CCRT) for esophageal cancer patient with esophageal metallic stent insertion is a rare condition. A 52-year-old man with esophageal cancer, cT4N1M0, stage IIIC, was treated with concurrent weekly cisplatin (30 mg/m2) and 5-Fluorouracil (500 mg/m2) as well as radiotherapy (50.4 Gy in 28 fractions) for 6 weeks. An esophageal metallic stent was inserted for dysphagia 1 week after initiation of CCRT. During the treatment regimen, the platelet count dropped to less than 200 × 103 /μL. One month after the completion of CCRT, chest CT revealed the presence of an aortic pseudoaneurysm as well as aortoesophageal fistulas. A thoracic aortic endografting was performed and the patient responded well to surgery. However, the patient died 2 months later due to a nosocomial infection. Multimodality treatment for esophageal cancer comprising cisplatin-based CCRT and esophageal metallic stent placement near a great vessel may increase the risk of pseudoaneurysm formation.

    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 < .001). The adjusted hazard ratio (HR) was 2.24 (95 % confidence interval, CI = 1.95-2.56, P < .001) in the esophageal cancer cohort compared with the matched cohort. Independent risk factors for developing 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.

    Background Patients undergoing treatment for esophagogastric or esophageal cancer are exposed to a considerably high risk of malnutrition due to early obstruction of the gastrointestinal passage. Presently most of the patients undergo modern multimodal therapies which require chemoradiation or chemotherapy ahead of surgery. Therefore reconstruction of the obstructed gastrointestinal passage is considerably delayed. Surgery as the only curative option after neoadjuvant treatment is the mainstay of therapy in this setting. However, many patients are at risk for the development of postoperative complications associated with the complexity of the surgical procedure. Therefore enteral feeding as a prerequisite to avoid malnutrition represents a special therapeutic challenge. Summary This review describes the recent literature on the incidence and influence of perioperative malnutrition on oncologic outcome, measures to determine patients at risk, possible strategies to reduce or avoid malnutrition by supportive enteral/parenteral nutrition, implementation of the enhanced recovery after surgery programs and feeding routes, but also surgical and adjuvant procedures in the curative and palliative setting for patients undergoing treatment for gastroesophageal cancers Key Messages Appropriate identification of patients at risk is crucial to avoid malnutrition. Early nutritional interventions during multimodal/neoadjuvant treatment may be beneficial for weight loss reduction although the evidence is not conclusive. Pouch reconstructions during surgery should be applied in order to increase quality of life and eating capacity. Reduction of postoperative complications could provide potential benefits. In palliative patients, insertion of self-expanding metal stents can reduce dysphagia and improve quality of life, but does not prolong overall survival. Further evidence is required to determine the value of the procedures and measures described in this review Practical

    We have recently shown that HMGA2 is overexpressed in esophageal squamous cell carcinoma (ESCC) and its detection allows to discriminate between cancer and normal surrounding tissue proposing HMGA2 as a novel diagnostic marker. Interestingly, esophageal adenocarcinoma shows an opposite behavior with the overexpression of HMGA1 but not HMGA2. Moreover, we show that the suppression of HMGA2 in 2 ESCC cell lines reduces the malignant phenotype. Then, this paper highlights a differential induction of the HMGA proteins, depending on the cancer histological type, and reinforces the perspective of an innovative esophageal cancer therapy based on the suppression of the HMGA protein function and/or expression.

    Purpose: To investigate the dose-volume histogram parameters and clinical factors as predictors of pleural effusion in esophageal cancer patients treated with concurrent chemoradiotherapy (CRT). Methods and Materials: Forty-three esophageal cancer patients treated with definitive CRT from January 2001 to March 2007 were reviewed retrospectively on the basis of the following criteria: pathologically confirmed esophageal cancer, available computed tomography scan for treatment planning, 6-month follow-up after CRT, and radiation dose {>=}50 Gy. Exclusion criteria were lung metastasis, malignant pleural effusion, and surgery. Mean heart dose, mean total lung dose, and percentages of heart or total lung volume receiving {>=}10-60 Gy (Heart-V{sub 10} to V{sub 60} and Lung-V{sub 10} to V{sub 60}, respectively) were analyzed in relation to pleural effusion. Results: The median follow-up time was 26.9 months (range, 6.7-70.2) after CRT. Of the 43 patients, 15 (35%) developed pleural effusion. By univariate analysis, mean heart dose, Heart-V{sub 10} to V{sub 60}, and Lung-V{sub 50} to V{sub 60} were significantly associated with pleural effusion. Poor performance status, primary tumor of the distal esophagus, and age {>=}65 years were significantly related with pleural effusion. Multivariate analysis identified Heart-V{sub 50} as the strongest predictive factor for pleural effusion (p = 0.01). Patients with Heart-V{sub 50} <20%, 20%{<=} Heart-V{sub 50} <40%, and Heart-V{sub 50} {>=}40% had 6%, 44%, and 64% of pleural effusion, respectively (p < 0.01). Conclusion: Heart-V{sub 50} is a useful parameter for assessing the risk of pleural effusion and should be reduced to avoid pleural effusion.

    The capability of using silver nanoparticle based near-infrared surface enhanced Raman scattering (SERS) spectroscopy combined with principal component analysis (PCA) and linear discriminate analysis (LDA) to differentiate esophageal cancer tissue from normal tissue was presented. Significant differences in Raman intensities of prominent SERS bands were observed between normal and cancer tissues. PCA-LDA multivariate analysis of the measured tissue SERS spectra achieved diagnostic sensitivity of 90.9% and specificity of 97.8%. This exploratory study demonstrated great potential for developing label-free tissue SERS analysis into a clinical tool for esophageal cancer detection.

    Murine double minute 2 (MDM2) has suggested to play an important role in esophageal cancer. The association between MDM2 T309G polymorphism and esophageal cancer risk was inconclusive. To clarify the possible association, we conducted a meta-analysis. We searched in the PubMed, Embase, and Wanfang databases. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of association. A total of 6 studies with 4909 cases and controls were included based on the search criteria. The MDM2 T309G polymorphism was associated with a significantly decreased risk of esophageal cancer (OR=0.88; 95% CI, 0.81-0.96; I(2)=22%). When stratified by type of race, a significantly decreased esophageal cancer risk were observed in Asians (OR=0.85; 95% CI, 0.78-0.93; I(2)=0%). In conclusion, this meta-analysis suggested that MDM2 T309G polymorphism was associated with a significantly decreased risk of esophageal cancer.

    Few studies have examined the clinical characteristics of patients with brain metastases from small-cell esophageal cancer. In this study, we review the clinical characteristics and outcomes in patients with brain metastases from small-cell esophageal cancer. From August 2002 to August 2012, consecutive patients diagnosed with brain metastases from small-cell esophageal cancer and treated with radiotherapy were enrolled. Clinical features, diagnostic findings, and survival were analyzed. Six patients treated with brain radiotherapy were identified. The median age was 64 (range 61-74) years. All patients had neurological impairments. Three patients had supra- and infra-tentorial metastases, and three patients had cerebrum metastases. Brain metastases were detected when esophageal cancer was initially diagnosed in two patients. In three patients, magnetic resonance imaging findings after radiotherapy confirmed a significant response to treatment. The median overall survival was 6.0 months. During the same period, 43 patients with squamous cell carcinoma and seven patients with adenocarcinoma who had brain metastases were identified. Survival periods for squamous cell carcinoma and adenocarcinoma patients who had brain metastases were 5.5 months and 4.2 months, respectively. There was no significant difference in overall survival according to the histological type. Brain metastases from small-cell esophageal cancer tend to spread to the cerebellum and impair patients' quality-of-life. Brain radiotherapy had a positive effect in this case series; however, overall survival remains short.

    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.

    Hypomagnesemia is one of the well-known side effects in patients receiving cisplatin-containing chemotherapy. However, the relevance between hypomagnesemia and cisplatin-induced nephrotoxicity remain to be completely elucidated. Although patients with esophageal and hypopharyngeal cancer are susceptible to dehydration, there is no evidence yet that magnesium supplementation for these patients will prevent nephrotoxicity during cisplatin-containing chemotherapy. The aim of this study was to examine the effect of magnesium supplementation on the prevention of cisplatin-induced nephrotoxicity for patients with esophageal and hypopharyngeal cancer. Twenty-three patients with esophageal or hypopharyngeal cancer were studied over 2 weeks. Ten of them received magnesium supplementation and 13 did not. Magnesium sulphate(20 mEq) was administered before 5-fluorouracil(800mg/m2/24 h/day 1-5)and cisplatin(80mg/m2/day 1)(FP)treatment. The maximum serum creatinine concentration of magnesium-supplemented group demonstrated a significantly lower concentration compared to the non-magnesium-supplemented group(p=0. 018). As a result, magnesium supplementation successfully reduced the incidence rate of nephrotoxicity(p=0. 038). These results showed that magnesium supplementation before FP treatment may be quite beneficial for preventing nephrotoxicity in patients with esophageal and hypopharyngeal cancer, and it is therefore recommended that magnesium be routinely supplemented during FP treatment for esophageal or hypopharyngeal cancer.

    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. © 2014 APJPH.

    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 dysplasia 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 RMB 2707 to RMB 4512, and the total cost on screening and treatment was RMB 13 115-14 920. The cost benefit was RMB 58 944-155 110 (the saved treatment cost, RMB 17 730, plus the value of prolonged life, RMB 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 authors examined the sensitivities of esophageal cancer to Bleomycin (BLM), Peplomycin (PEP), Cisplatin (CDDP) and 5-FU by the INAS method using 3H-thymidine or 14C-formate as labeled precursors, and determined the concentrations of anticancer agents in cancer lesions by the Band Culture method. On the other hand, the authors investigated the superiority or inferiority of various methods of BLM administration by observing the prevention effect of BLM on the development of experimental esophageal cancer in rats. Forty-three cases out of 76, 57%, showed a sensitivity to BLM, 60% to PEP, 38% to CDDP and 56% to 5-FU. As to the types of roentgenological findings, the superficial and tumorous types showed a high sensitivity rate. As to the types of macroscopical findings, the protruded and superficial types showed a high sensitivity rate. As to the types of histological findings, well differentiated squamous cell carcinoma showed a high sensitivity rate. Sensitivity was higher in metastatic lymph nodes than in main cancer lesions. Tumor tissues which had undergone previous hyperthermic management (at 42 degrees C) showed a higher sensitivity than those which had not. PEP at a half dose brought about the same grade of anticancer effect as BLM. The sensitivities of esophageal cancer to various anticancer agents showed individual differences among clinical cases. Therefore, combination chemotherapy for esophageal cancer was thought to be an effective administration method. The divided administration of small doses of BLM was thought to be more superior than the one-shot administration of a large dose for esophageal cancer. The results of the INAS sensitivity test were perfectly coincident with the effects of chemotherapy in clinical cases of esophageal cancer.

    Open esophagectomy (OE) requires extensive surgery and is associated with significant morbidity and mortality. Furthermore, the long-term results of esophageal cancer surgery are not satisfactory; hence, the best surgical approach is constantly under debate. During the last twenty years, minimally invasive esophagectomy (MIE) employing laparoscopy and/or thoracoscopy has been introduced in a growing number of centers worldwide. To date, several studies have demonstrated that MIE has better outcomes than OE, as it results in shorter hospital stay and decreased overall morbidity. However, the length of operating time in MIE is increased in comparison to OE. The survival benefit has been demonstrated to be similar in OE and MIE. Highly advanced laparo-thoracoscopic skills are required to perform MIE; along with the relatively long learning curve, this makes MIE feasible only in high-volume, experienced university surgical centers. There is a need for further large-scale comparative studies to prove the superiority of MIE over open surgery. PMID:26336413

    The main objective of the present work is to study the influence of heat treatment on the esophageal cancer detection using the diffuse reflectance (DR) spectral intensity ratio R540/R575 of oxygenated hemoglobin (HbO2) absorption bands to distinguish the epithelial tissues of normal human esophagus and moderately differentiated esophageal squamous cell carcinoma (ESCC) at different heat treatment temperature of 20, 37, 42, 50, and 60°C, respectively. The DR spectra for the epithelial tissues of the normal esophagus and ESCC in vitro at different heat-treatment temperature in the wavelength range 400-650 nm were measured with a commercial optical fiber spectrometer. The results indicate that the average DR spectral intensity overall enhancement with concomitant increase of heat-treatment temperature for the epithelial tissues of normal esophagus and ESCC, but the average DR spectral intensity for the normal esophageal epithelial tissues is relatively higher than that for ESCC epithelial tissues at the same heat-treatment temperature. The mean R540/R575 ratios of ESCC epithelial tissues were always lower than that of normal esophageal epithelial tissues at the same temperature, and the mean R540/R575 ratios of the epithelial tissues of the normal esophagus and ESCC were decreasing with the increase of different heat-treatment temperatures. The differences in the mean R540/R575 ratios between the epithelial tissues of normal esophagus and ESCC were 13.33, 13.59, 11.76, and 11.11% at different heat-treatment temperature of 20, 37, 42, and 50°C, respectively. These results also indicate that the DR intensity ratio R540/R575 of the hemoglobin bands is a useful tool for discrimination between the epithelial tissues of normal esophagus and ESCC in the temperature range from room temperature to 50°C, but it was non-effective at 60°C or over 60°C.

    The aim of palliation in patients with inoperable esophageal cancer is to relieve dysphagia with minimal morbidity and mortality, and thus improve quality of life (QOL). The use of a self-expanding metal stent (SEMS) is a well-established modality for palliation of dysphagia in such patients. We assessed the QOL after palliative stenting in patients with inoperable esophageal cancer. Thirty-three patients with dysphagia due to inoperable esophageal cancer underwent SEMS insertion between October 2004 and December 2006. All patients had grade III/IV dysphagia and locally advanced unresectable cancer (n = 13), distant metastasis (n = 14), or comorbid conditions/poor general health status precluding a major surgical procedure (n = 6). Patients with grade I/II dysphagia and those with carcinoma of the cervical esophagus were excluded. The QOL was assessed using the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 (version 3) and EORTC QLQ-Esophagus (OES) 18 questionnaire (a QOL scale specifically designed for esophageal diseases) before and at 1, 4, and 8 weeks after placement of the stent. The mean age of the patients was 56 (range 34-78) years, and 22 were men. A covered SEMS was used in all patients. The most common site of malignancy was the lower third of the esophagus (n = 18, 55%). In 23 (77%) patients, the stent crossed the gastroesophageal junction. Seven patients required a reintervention for stent block (n = 5) and stent migration (n = 2). Dysphagia improved significantly immediately after stenting, and this improvement persisted until 8 weeks (16.5 vs. 90.6; P < 0.01). The global health status (5.8 vs. 71.7; P < 0.01) and all functional scores improved significantly after stenting from baseline until 8 weeks. Except pain (14.1 vs. 17.7; P = 0.67), there was significant improvement in deglutition (22.7 vs. 2.0; P < 0.01), eating (48 vs. 12.6; P < 0.01), and other symptom scales (19.7 vs. 12.1; P = 0.04) following stenting.

    Currently, esophageal cancer is rarely curable, and herein, a paclitaxel or 5-fluorouracil/esophageal stent combination (PTX or 5-FU/stent) was used to provide a new approach to treat this cancer. The PTX or 5-FU/stent was prepared by covering a nitinol stent with a bilayered polymer film that consisted of a layer of 50% PTX or 5-FU and a layer of drug-free backing. These treatment modalities were evaluated in vivo after implantation into the porcine esophagus. The percentages of the drugs that permeated from the backing layer over a period of 95 days were very small (0.61% for 5-FU), and an overwhelming majority of the PTX and the 5-FU was released from the other side of the film. During the follow-up period (120 days), the drug/stent was always maintained in the porcine esophagus, and did not show any obvious systemic or local toxicities. In contrast, this treatment had an effect on the inhibition of tissue proliferation and ulceration. In addition, the drug concentrations were highest in the esophagus compared with in the heart, liver, spleen, lung, kidney and blood (81500.0 ± 9475.2 ng/g vs. 3.9 ± 0.3 ng/mL of PTX in the plasma at 13 days). The PTX/stent and the 5-FU/stent have a dual function as both a stent and a local drug delivery device, which provides a potential treatment modality with high efficacy and non systematic toxicity for esophageal cancer.

    Purpose: To evaluate the factors associated with acute esophagitis in lung cancer patients treated with thoracic radiotherapy. Methods and Materials: We examined 35 patients with non-small-cell lung cancer (n = 27, 77%) and small-cell lung cancer (n = 8, 23%) treated with thoracic radiotherapy between February 2003 and November 2004. The median patient age was 70 years (range, 50-83 years). The disease stage was Stage I in 2 patients (6%), Stage II in 1 (3%), Stage IIIa in 10 (28%), Stage IIIb in 9 (26%), and Stage IV in 9 (26%); 4 patients (11%) had recurrent disease after surgery. A median dose of 60 Gy (range, 50-67 Gy) was given to the isocenter and delivered in single daily fractions of 1.8 or 2 Gy. With heterogeneity corrections, the median given dose to the isocenter was 60.3 Gy (range, 49.9-67.2 Gy). Of the 35 patients, 30 (86%) received concurrent chemotherapy consisting of a platinum agent, cisplatin or carboplatin, combined with paclitaxel in 18 patients (52%), irinotecan hydrochloride in 7 (20%), vincristine sulfate and etoposide in 2 (5%), vinorelbine ditartrate in 1 (3%), etoposide in 1 (3%), and docetaxel in 1 patient (3%). Three of these patients underwent induction therapy with cisplatin and irinotecan hydrochloride, administered before thoracic radiotherapy, and concurrent chemotherapy. Esophageal toxicity was graded according to the Radiation Therapy Oncology Group criteria. The following factors were analyzed with respect to their association with Grade 1 or worse esophagitis by univariate and multivariate analyses: age, gender, concurrent chemotherapy, chemotherapeutic agents, maximal esophageal dose, mean esophageal dose, and percentage of esophageal volume receiving >10 to >65 Gy in 5-Gy increments. Results: Of the 35 patients, 25 (71%) developed acute esophagitis, with Grade 1 in 20 (57%) and Grade 2 in 5 (14%). None of the patients had Grade 3 or worse toxicity. The most significant correlation was between esophagitis and percentage of

    Trichosporon species are usually opportunistic pathogens. Here, we present a case of esophagitis caused by T. inkin in a 54-year-old woman with pulmonary cancer and severe neutropenia in whom the susceptibility profile of the isolate against azoles and polyenes was verified. The patient was diagnosed with esophagitis grade I of Wilcox, presenting scattered whitish plaques and exudates in upper two-thirds of the esophageal mucosa. Antifungal therapy involving oral fluconazole (150 mg/day for 14 days) was ineffective. In vitro, the isolate showed no resistance to this azole and sensitivity to amphotericin B. Since T. inkin is of growing importance as an agent of invasive infections in immunocompromised patients, we stress that the diagnosis of esophagitis by this species should be followed by an assessment of the therapeutic sensitivity of the strain involved.

    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. PMID:23560033

    Background: Esophageal cancer remains associated with poor outcomes, yet little is known regarding factors that influence survival. Aspirin use prior to cancer diagnosis may influence outcomes. We aimed to assess the effects of prediagnosis aspirin use in patients with esophageal cancer. Methods: We conducted a prospective cohort study of newly-diagnosed esophageal cancer patients at two tertiary care centers. We assessed history of prediagnosis aspirin use, and prospectively followed patients and assessed mortality, cause of death, and development of metastases. Results: We enrolled 130 patients, the majority of whom were male (81.5%) and had adenocarcinoma (80.8%). Overall, 57 patients (43.9%) were regular aspirin users. In unadjusted analyses, we found no difference in all-cause mortality between aspirin users and nonusers. In multivariate analyses, prediagnosis aspirin use was not associated with all-cause mortality [hazard ratio (HR) 0.86, 95% confidence interval (CI) 0.48–1.57] or esophageal cancer-specific mortality (HR 1.07, 95% CI 0.52–2.21). Prediagnosis aspirin use was associated with a significantly increased risk of interval metastasis (HR 3.59, 95% CI 1.08–11.96). Conclusions: In our cohort of esophageal cancer patients, prediagnosis aspirin use was not associated with all-cause or cancer-specific mortality. However, risk of interval metastatic disease was increased among those who took aspirin regularly prediagnosis. Future studies are warranted to assess whether aspirin influences the molecular characteristics of esophageal tumors, with potential prognostic and therapeutic implications. PMID:27803735

    Esophageal cancer is difficult to cure globally and possesses high mortality rate, and it is generally accepted that palliative care such as stent implantation is the main therapy method for esophageal cancer in later period. However, the restenosis caused by tumor cells and inflammatory cells seriously interferes the stent clinical application and limits its long-term services. To solve this problem, series of drug delivery stents were developed and proven rather effective in the early stage of implantation, but more serious restenosis occurred after the drug delivery was over, which endangered the patients' life. Therefore, endowing the esophageal stent continuous anti-cancer function become an ideal strategy for inhibiting the restenosis. In this contribution, the functional layer composed of polydopamine (PDA) and Poly-ethylenimine (PEI) with series of molecular weights (MW, 1.8 × 10(3), 1 × 10(4), 2.5 × 10(4) and 7 × 10(4) Da) were fabricated onto the esophageal stent material 317L stainless steel (317L SS) surface. The surface characterization including amine quantitative, atomic force microscopy (AFM) and water contact angle measurement indicated successful preparation of the PDA/PEI layer. The Eca109 cells culture results proved that the PDA/PEI layers significantly improve Eca109 cells apoptosis and necrosis, suggesting excellent anti-cancer function. In addition, we also found that the anti-cancer function of the PDA/PEI layers was positively correlated to the immobilized PEIs' MW. All the results demonstrated the potential application of the PDA/PEI layers on the surface modification of esophageal stent for continuous anti-cancer function. It is generally accepted that the restenosis caused by tumor cells seriously interferes the esophageal stent clinical application. Thus, endowing the esophageal stent continuous anti-cancer function is the ideal strategy for inhibiting the restenosis. In this work, we fabricated functional layers

    The Aurora-A gene encodes a serine/threonine protein kinase that is frequently overexpressed in several types of human tumors. The overexpression of Aurora-A has been observed to associate with the grades of differentiation, invasive capability and distant lymph node metastasis of esophageal squamous cell carcinoma (ESCC). However, the molecular mechanism by which Aurora-A promotes malignant development of ESCC is still largely unknown. In this study, we show that Aurora-A overexpression enhances tumor cell invasion and metastatic potential in vitro and in vivo. Furthermore, Aurora-A overexpression inhibits the degradation of β-catenin, promotes its dissociation from cell-cell contacts and increases its nuclear translocation. We also demonstrate for the first time that Aurora-A directly interacts with β-catenin and phosphorylates β-catenin at Ser552 and Ser675. Substitutions of serine residue with alanine at single or both positions substantially attenuate Aurora-A-mediated stabilization of β-catenin, abolish its cytosolic and nuclear localization as well as transcriptional activity. In addition, Aurora-A overexpression is significantly correlated with increased cytoplasmic β-catenin expression in ESCC tissues. In view of our results, we propose that Aurora-A-mediated phosphorylation of β-catenin is a novel mechanism of malignancy development of tumor.

    Radiotherapy (RT) or chemoradiotherapy (CRT) is a potentially curative, non-surgical treatment option for esophageal cancer, although the rate of local failure within the esophagus remains relatively high. Salvage esophagectomy is not regarded as a common treatment for esophageal cancer, since it is a high-risk surgery with a relatively high surgical mortality rate. Salvage endoscopic resection (ER) for local failure is used for treatment when esophageal cancer is localized and superficial. To evaluate to usefulness of salvage ER, the present study reviewed the clinicopathological records and follow-up data of 37 patients that underwent salvage ER for esophageal cancer, following initial treatment with RT or CRT. Salvage ER was conducted on a total of 78 lesions observed in the 37 patients. Since a thick epithelium and lack of normal vessels on the surface of the mucosa are characteristics of esophageal mucosa following RT or CRT, almost all the lesions were detected using iodine dyeing, and not by narrow band imaging. The growth rate of the detected lesions was relatively high, and early treatment was required. No particular complications occurred during the endoscopic treatment. A total of 11 patients survived for >5 years subsequent to initial endoscopic treatment. Only 4 patients succumbed to esophageal cancer. In conclusion, the present study demonstrated that salvage ER following CRT or RT for esophageal cancer is a minimally invasive, safe, adaptive and curative method for superficial lesions without distant metastases in patients with esophageal cancer with local failure following CRT or RT.

    ABO blood type is an established prognostic factor in several malignancies, but its role in esophageal cancer (EC) is largely unknown. The aim of this study is to determine whether ABO blood group is associated with survival after esophagectomy for EC. A total of 406 patients who underwent surgery for EC were enrolled. The associations of ABO blood group with clinical and pathological variables were assessed using chi-square test. Associations of ABO blood group with the survival were estimated using univariable and multivariable Cox proportional hazards regression models. The ABO blood group proportionally associated with the grade of EC tumor (P = 0.049). The ABO blood group status did not correlate with disease-free survival (DFS) in univariable analysis or multivariable analysis (P > 0.05). And there was no significant relationship between the ABO blood group and overall survival (OS) in univariable analysis or multivariable analysis (P > 0.05). Our results suggested that no association between ABO blood group and the survival was observed in patients undergoing surgery for EC.

    High throughput methodologies have revealed the existence of an unexpectedly large number of long noncoding RNAs (lncRNAs). The unconventional role of lncRNAs in gene expression regulation and their broad implication in oncogenic and tumor suppressive pathways have introduced lncRNAs as novel biological tumor markers. The most prominent example of lncRNAs application in routine clinical practice is PCA3, a FDA-approved biomarker for prostate cancer. Regarding digestive system malignancies, the oncogenic HOTAIR is one of the most widely studied lncRNAs in the preclinical level and has already been identified as a potent prognostic marker for major malignancies of the gastrointestinal tract. Here, we provide an overview of recent findings regarding the emerging role of lncRNAs not only as key regulators of cancer initiation and progression in colon, stomach, pancreatic, liver, and esophageal cancers, but also as reliable tumor markers and therapeutic tools. lncRNAs can be easily, rapidly, and cost-effectively determined in tissues, serum, and gastric juice, making them highly versatile analytes. Taking also into consideration the largely unmet clinical need for early diagnosis and more accurate prognostic/predictive markers for gastrointestinal cancer patients, we comment upon the perspectives of lncRNAs as efficient molecular tools that could aid in the clinical management.

    Barrett's esophagus is a known precursor lesion to esophageal adenocarcinoma. In these patients, early detection of premalignant disease, known as dysplasia, allows curative minimally invasive endoscopic therapy, but is confounded by a lack of contrast in white light endoscopy. Imaging fluorescently labeled lectins applied topically to the tissue has the potential to more accurately delineate dysplasia, but tissue autofluorescence limits both sensitivity and contrast when operating in the visible region. To overcome this challenge, we synthesized near-infrared (NIR) fluorescent wheat germ agglutinin (WGA-IR800CW) and constructed a clinically translatable bimodal NIR and white light endoscope. Images of NIR and white light with a field of view of 63 deg and an image resolution of 182 μm are coregistered and the honeycomb artifact arising from the fiber bundle is removed. A minimum detectable concentration of 110 nM was determined using a dilution series of WGA-IR800CW. We demonstrated ex vivo that this system can distinguish between gastric and squamous tissue types in mouse stomachs (p=0.0005) and accurately detect WGA-IR800CW fluorescence in human esophageal resections (compared with a gold standard imaging system, rs>0.90). Based on these findings, future work will optimize the bimodal endoscopic system for clinical trials in Barrett's surveillance.

    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.

    CD44v6 is a cell adhesion molecule that plays an important role in the development and progression of esophageal cancer. However, the prognostic value and clinical significance of CD44v6 in esophageal cancer remains controversial. In the present study, we aimed to clarify these relationships through a meta-analysis.We performed a comprehensive search of studies from PubMed, EMBASE, Ovid library database, Google scholar, and Chinese National Knowledge Infrastructure databases that were published before June 2015. The odds ratio (OR) and pooled hazard ratio (HR) with the 95% confidence intervals (CI) were used to estimate the effects.Twenty-one studies including 1504 patients with esophageal cancer were selected to assess the prognostic value and clinical significance of CD44v6 in these patients. The results showed that the expression of CD44v6 was higher in esophageal cancer tissue than in normal colorectal tissue (OR=9.19, 95% CI=6.30-13.42). Moreover, expression of CD44v6 was higher in patients with lymphoid nodal metastasis, compared to those without (OR=6.91, 95% CI=4.81-9.93). The pooled results showed that CD44v6 was associated with survival in patients with esophageal cancer (HR = 2.47, 95% CI = 1.56-3.92). No significant difference in CD44v6 expression was found in patients with different histological types and tumor stages (both P>0.05). Moreover, no publication bias was found among the studies (all P > 0.05).This meta-analysis demonstrates that CD44v6 is associated with the metastasis of esophageal cancer and a poor prognosis, but is not associated with the histological types and tumor stages.

    Photodynamic therapy (PDT) has gathered much attention in the field of cancer treatment and is increasingly used as an alternative solution for esophageal cancer therapy. However, there is a constant need for improving the effectiveness and tolerability of the applied photosensitizers (PS). Here, we propose tetra-triethyleneoxysulfonyl substituted zinc phthalocyanine (ZnPc) as a promising PS for photodynamic treatment of esophageal cancer. ZnPc-induced phototoxicity was studied in two human esophageal cancer cell lines: OE-33 (adenocarcinoma) and Kyse-140 (squamous cell carcinoma). In vitro studies focused on the uptake and intracellular distribution of the novel ZnPc as well as on its growth inhibitory potential, reactive oxygen species (ROS) formation and the induction of apoptosis. The chicken chorioallantoic membrane assay (CAM assay) and studies on native Wistar rats were employed to determine the antineoplastic and antiangiogenic activity of ZnPc-PDT as well as the tolerability and safety of non-photoactivated ZnPc in vivo. ZnPc was taken up by cancer cells in a dose- and time-dependent manner and showed a homogeneous cytoplasmic distribution. Photoactivation of ZnPc-loaded (1-10 µM) cells led to a dose-dependent growth inhibition of esophageal adenocarcinoma and squamous cell carcinoma cells of >90%. The antiproliferative effect was based on ROS-induced cytotoxicity and the induction of mitochondria-driven apoptosis. In vivo studies on esophageal tumor plaques grown on the CAM revealed pronounced antiangiogenic and antineoplastic effects. ZnPc-PDT caused long-lasting changes in the vascular architecture and a marked reduction of tumor feeding blood vessels. Animal studies confirmed the good tolerability and systemic safety of ZnPc, as no changes in immunological, behavioral and organic parameters could be detected upon treatment with the non-photoactivated ZnPc. Our findings show the extraordinary photoactive potential of the novel ZnPc as a

    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 adenocarcinoma (EAC) has been rapidly increasing in Western countries during the past half century, especially in white men. Esophageal squamous cell carcinoma (ESCC) used to be the dominant type of esophageal malignancy both in Western and Asian countries. The rapid increase of EAC in Western countries has occurred in parallel with an increased prevalence of gastroesophageal reflux disease (GERD) and its major determinant, obesity. Such an increase in EAC has not yet been observed in Asia, despite a recent increase in prevalence of GERD. In this mini-review, we analyze possible factors influencing such east-west ('Orient to Occident') differences, particularly possible roles of ethnicity and environmental factors, such as Helicobacter pylori infection and nutritional factors, and how these might interact with socioeconomic differences. Development of Barrett's esophagus and esophageal adenocarcinoma appears to be strongly affected by ethnic factors, with populations resident at the west end of the Eurasian continent, such as Anglo-Celtics, being more prone to both conditions. On the other hand, ethnic groups from the eastern and southern ends of Eurasia, such as Chinese, Koreans and Japanese, and Africans might be more prone to developing esophageal squamous cell carcinoma. Future trends will also be discussed.

    Pneumo-computed tomography (PnCT) is a technique primarily developed and used to study stenotic lesions of the esophagus, gastroesophageal junction and stomach for pre-surgical planning. It helps to define both upper and lower borders of neoplasms located in the aforementioned areas. It achieves maximum lumen distension with CO2 highlighting thickened areas of the esophageal wall, thus allowing an accurate quantification of their extents. Although there are other alternatives for distension (oral contrast agents, water and effervescent granules), they may be suboptimal. Patients with locally advanced esophageal cancer have a dismal prognosis despite surgical resection. Therefore, neoadjuvant treatment strategies using radiation therapy and chemotherapy were developed to improve survival. Neoadjuvant therapy improves esophageal tumor prognosis in a substantial proportion of patients, and the use of imaging techniques is mandatory to detect their response. PnCT combined with virtual endoscopy and multiplanar reconstruction enhances morphologic details in esophageal cancer, and thus would allow an improved assessment of response to neoadjuvant treatment. Therefore, more information could be provided to assess the efficacy of pre-surgical treatment. We describe the potential use of PnCT to assess the response to neoadjuvant therapy in esophageal cancer with an imaging pathologic correlation.

    This study tests the hypothesis that prediagnostic serum levels of 20 cancer-associated inflammatory biomarkers correlate directly with future development of head and neck, esophageal, and lung cancers in a high-risk prospective cohort. This is a nested case-control pilot study of subjects enrolled in the Golestan Cohort Study, an ongoing epidemiologic project assessing cancer trends in Golestan, Iran. We measured a panel of 20 21 cytokines, chemokines, and inflammatory molecules using Luminex technology in serum samples collected 2 or more years before cancer diagnosis in 78 aerodigestive cancer cases and 81 controls. Data was analyzed using Wilcoxon rank sum test, odds ratios, receiver operating characteristic areas of discrimination, and multivariate analysis. Biomarkers were profoundly and globally elevated in future esophageal and lung cancer patients compared to controls. Odds ratios were significant for association between several biomarkers and future development of esophageal cancer, including interleukin-1Rα (IL-1Ra; 35.9), interferon α2 (IFN-a2; 34.0), fibroblast growth factor-2 (FGF-2; 17.4), and granulocyte/macrophage colony-stimulating factor (GM-CSF; 17.4). The same pattern was observed among future lung cancer cases for G-CSF (27.7), GM-CSF (13.3), and tumor necrosis factor-α (TNF-a; 8.6). By contrast, the majority of biomarkers studied showed no significant correlation with future head and neck cancer development. This study provides the first direct evidence that multiple inflammatory biomarkers are coordinately elevated in future lung and esophageal cancer patients 2 or more years before cancer diagnosis. © 2014 The Authors.

    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.

    Several studies suggest that agricultural workers are at higher risk to develop and die by certain types of cancer. Esophageal cancer is not commonly listed among these types. However, some recent studies indicated that if there is an association between agricultural working and esophageal cancer, it s more likely to be observed among workers highly exposed to pesticides. In the present study, the magnitude of the association between agricultural working and esophageal cancer mortality was evaluated in a high pesticide use area in Brazil, through a death certificate-based case-control study. Cases were individuals from both genders, 30-59 years old, for whom basic cause of death was ascertained as cancer of the esophagus. For each case, one control was randomly selected from all possible controls for which the basic cause of death was ascertained as different from neoplasm and diseases of the digestive system. In addition, controls matched their cases by sex, age, year of death, and state of residence. Crude and adjusted odds ratios were then calculated to estimate the magnitude of the risk. Results showed that, in general, agricultural workers were at significantly higher risk to die by esophageal cancer, when compared to non-agricultural workers. Stratified analysis also revealed that the magnitude of such risk was slightly higher among illiterate agricultural workers, and simultaneous adjustment for several covariates showed that the risk was quantitatively higher among younger southern agricultural workers. These results suggest the esophageal cancer may be included among those types of cancer etiologically associated to agricultural working. Copyright © 2010 Elsevier GmbH. All rights reserved.

    Background: The 7th edition of the American Joint Committee on Cancer staging system does not include lymph node size in the guidelines for staging patients with esophageal cancer. The objectives of this study were to determine the prognostic impact of the maximum metastatic lymph node diameter (ND) on survival and to develop and validate a new staging system for patients with esophageal squamous cell cancer who were treated with definitive chemoradiotherapy (CRT). Methods: Information on 402 patients with esophageal cancer undergoing CRT at two institutions was reviewed. Univariate and multivariate analyses of data from one institution were used to assess the impact of clinical factors on survival, and recursive partitioning analysis was performed to develop the new staging classification. To assess its clinical utility, the new classification was validated using data from the second institution. Results: By multivariate analysis, gender, T, N, and ND stages were independently and significantly associated with survival (p < 0.05). The resulting new staging classification was based on the T and ND. The four new stages led to good separation of survival curves in both the developmental and validation datasets (p < 0.05). Conclusions: Our results showed that lymph node size is a strong independent prognostic factor and that the new staging system, which incorporated lymph node size, provided good prognostic power, and discriminated effectively for patients with esophageal cancer undergoing CRT.

    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.

    A protective effect of female sex hormones has been suggested to explain the male predominance in esophageal and gastric adenocarcinoma, but evidence is lacking. We aimed to test whether menopausal hormone therapy (MHT) decreases the risk of these tumors. For comparison, esophageal squamous cell carcinoma was also assessed. This population-based matched cohort study included all women who had ever used systemic MHT in Sweden in 2005-2012. A comparison cohort of non-users of MHT was matched to the MHT-users regarding age, parity, thrombotic events, hysterectomy, diabetes, obesity, smoking-related diseases and alcohol-related diseases. Individuals with any previous cancer were excluded. Data on MHT use, cancer, comorbidity and mortality were collected from well-established Swedish nationwide registers. Odds ratios (OR) with 95% confidence intervals (CI) were calculated using conditional logistic regression. Different MHT regimens and age groups were compared in sub-group analyses. We identified 290,186 ever-users and 870,165 non-users of MHT. Ever-users had decreased ORs of esophageal adenocarcinoma (OR = 0.62, 95% CI 0.45-0.85, n = 46), gastric adenocarcinoma (OR = 0.61, 95% CI 0.50-0.74, n = 123) and esophageal squamous cell carcinoma (OR = 0.57, 95% CI 0.39-0.83, n = 33). The ORs were decreased for both estrogen-only MHT and estrogen and progestin combined MHT, and in all age groups. The lowest OR was found for esophageal adenocarcinoma in MHT-users younger than 60 years (OR = 0.20, 95% CI 0.06-0.65). Our study suggests that MHT-users are at a decreased risk of esophageal and gastric adenocarcinoma and also of esophageal squamous cell carcinoma. The mechanisms behind these associations remain to be elucidated. © 2016 UICC.

    Both ultrasound (US) and computed tomography (CT) can be used to detect supraclavicular lymph node metastases. Aim was to compare US, US plus fine-needle aspiration (US-FNA), CT, US + CT, and US-FNA + CT for the detection of these metastases in esophageal or gastric cardia cancer patients. Between 1994 and 2004, 567 patients underwent US and CT for esophageal or gastric cardia cancer staging. Gold standard was postoperative detection of lymph nodes in the resected specimen, FNA, or a radiological result with follow-up. Sensitivities of US (75%), US-FNA (72%), US + CT (80%), and US-FNA + CT (79%) were higher than sensitivity of CT alone (25%) (P < 0.001). Specificities were high for US-FNA (100%), CT (99%), and US-FNA + CT (99%), whereas those of US alone (91%) and US + CT (91%) were lower (P < 0.001). In 4/65 (6%) patients with true-positive malignant lymph nodes, CT was positive with US and/or US-FNA being negative. However, in 36/65 (55%) patients, US and/or US-FNA were positive with CT being negative. US-FNA seems the preferred diagnostic modality for the detection of supraclavicular lymph node metastases in patients with esophageal or gastric cardia cancer. Sensitivity of metastases detection only slightly improves if US-FNA is combined with CT. A prospective, comparative study is however needed. (c) 2007 Wiley-Liss, Inc.

    External beam radiotherapy (EBRT) treats gross tumors and local microscopic diseases. Radionuclide therapy by radioisotopes can eradicate tumors systemically. Rhenium 188 ((188)Re)-liposome, a nanoparticle undergoing clinical trials, emits gamma rays for imaging validation and beta rays for therapy, with biodistribution profiles preferential to tumors. We designed a combinatory treatment and examined its effects on human esophageal cancer xenografts, a malignancy with potential treatment resistance and poor prognosis. Human esophageal cancer cell lines BE-3 (adenocarcinoma) and CE81T/VGH (squamous cell carcinoma) were implanted and compared. The radiochemical purity of (188)Re-liposome exceeded 95%. Molecular imaging by NanoSPECT/CT showed that BE-3, but not CE81T/VGH, xenografts could uptake the (188)Re-liposome. The combination of EBRT and (188)Re-liposome inhibited tumor regrowth greater than each treatment alone, as the tumor growth inhibition rate was 30% with EBRT, 25% with (188)Re-liposome, and 53% with the combination treatment at 21 days postinjection. Combinatory treatment had no additive adverse effects and significant biological toxicities on white blood cell counts, body weight, or liver and renal functions. EBRT significantly enhanced the excretion of (188)Re-liposome into feces and urine. In conclusion, the combination of EBRT with (188)Re-liposome might be a potential treatment modality for esophageal cancer.

    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.

    The key prognostic factor which predicts outcome after esophagectomy for cancer is the number of malignant lymph node metastases, but data regarding the accuracy of endoscopic ultrasound (EUS) in determining and predicting the metastatic lymph node count preoperatively are limited. The aim of this study was to assess the prognostic significance of EUS defined lymph node metastasis count (eLNMC) in patients diagnosed with esophageal cancer. Two hundred and sixty-seven consecutive patients (median age 63 years, 187 months) underwent specialist EUS followed by stage directed multidisciplinary treatment (183 esophagectomy [64 neoadjuvant chemotherapy, 19 neoadjuvant chemoradiotherapy], 79 definitive chemoradiotherapy, and 5 palliative therapy). The eLNMC was subdivided into four groups (0, 1, 2 to 4, >4) and the primary measure of outcome was survival. Survival was related to EUS tumor (T) stage (P < 0.0001), EUS node (N) stage (P < 0.0001), EUS tumor length (p < 0.0001), and eLNMC (P < 0.0001). Multivariable analysis revealed EUS tumor length (hazard ratio [HR] 1.071, 95% CI 1.008-1.138, P= 0.027) and eLNMC (HR 1.302, 95% CI 1.133-1.496, P= 0.0001) to be significantly and independently associated with survival. Median and 2-year survival for patients with 0, 1, 2-4, and >4 lymph node metastases were: 44 months and 71%, 36 months and 59%, 24 months and 50%, and 17 months and 32%, respectively. The total number of EUS defined lymph node metastases was an important and significant prognostic indicator. © 2010 Copyright the Authors.

    Intramural hematoma of the esophagus (IHE) is an uncommon esophageal injury. Diagnosis requires high index of suspicion as it can mimic various other cardiovascular, pulmonary, mediastinal or esophageal diseases. Although multiple imaging modalities have been reported to be useful, CT with intravenous contrast should be the imaging modality of choice if not contraindicated. Treatment of IHE is mainly supportive; complete resolution in several weeks is the expected outcome. It is crucial that this condition is recognized and considered in the differential diagnosis of any patients who present with chest pain or dysphagia. PMID:24714326

    Altered microRNA (miRNA) expression has been found to promote carcinogenesis, but little is known about the role of miRNAs in esophageal cancer. In this study, we selected 10 miRNAs and analyzed their expression in 10 esophageal cancer cell lines and 158 tissue specimens using Northern blotting and in situ hybridization, respectively. We found that Let-7g, miR-21, and miR-195p were expressed in all 10 cell lines, miR-9 and miR-20a were not expressed in any of the cell lines, and miR-16-2, miR-30e, miR-34a, miR-126, and miR-200a were expressed in some of the cell lines but not others. In addition, transient transfection of miR-34a inhibited c-Met and cyclin D1 expression and esophageal cancer cell proliferation, whereas miR-16-2 suppressed RAR-β2 expression and increased tumor cell proliferation. Furthermore, we found that miR-126 expression was associated with tumor cell de-differentiation and lymph node metastasis, miR-16-2 was associated with lymph node metastasis, and miR-195p was associated with higher pathologic disease stages in patients with esophageal adenocarcinoma. Kaplan-Meier analysis showed that miR-16-2 expression and miR-30e expression were associated with shorter overall and disease-free survival in all esophageal cancer patients. In addition, miR-16-2, miR-30e, and miR-200a expression were associated with shorter overall and disease-free survival in esophageal adenocarcinoma patients; however, miR-16-2, miR-30e, and miR-200a expression was not associated with overall or disease-free survival in squamous cell carcinoma patients. Our data indicate that further evaluation of miR-30e and miR-16-2 as prognostic biomarkers is warranted in patients with esophageal adenocarcinoma. In addition, the role of miR-34a in esophageal cancer also warrants further study. PMID:20309880

    For a long time, the diagnosis and treatment protocol for esophageal cancer has been made either entirely based on the experience of Western countries or on our own experience alone. A suitable standardized guideline for diagnosis and treatment of esophageal cancer in our country has not been established until 2010. Due to lack of opportunities for mutual exchange and learning, the overall level of standardized diagnosis and treatment was relatively low in China. In addition, less advanced technologies were applied and varying treatment protocols were implemented in different districts, the treatment results has been unsatisfactory, and the overall 5-year survival rate after surgical treatment has been maintained from 30% to 40%. Therefore, it is imperative that China needs to conduct its own clinical studies and establish its own suitable standardized treatment and diagnosis guideline for esophageal cancer. This article reviews and also made comments on the process of academic speaking tour and development of standardized diagnosis and treatment guidelines as well as the problems resolved by these activities for esophageal cancer since the beginning of this century.

    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.

    In 1995, PDT was approved for palliative use in patients with esophageal cancer. We report our experience using PDT to treat esophageal cancer patients previously treated with combination chemotherapy and radiation therapy. In our series, nine patients referred for PDT with persistent esophageal cancer after chemo-radiation therapy. We found: (1) All patients were men with a mean age of 63 years and eight out of nine had adenocarcinoma with Barrett's esophagus; (2) All patients required endoscopic dilation after PDT; (3) At a mean follow up of 4 months, two T2N0 patients had no demonstrable tumor and all three T3N0 patients had greater than 50% tumor reduction (the partially responsive T3N0 patients will be offered repeat PDT); (4) Patients with metastatic disease (T3N1 or M1) had effective dysphagia palliation. Thus, PDT is safe and effective in ablating all or most tumor in patients with persistent esophageal cancer after chemotherapy and radiation therapy.

    Preserving functional walking capacity and nutritional status is important for patients with esophageal cancer, but no effective intervention is available, particularly during active treatment. This pilot randomized controlled trial tested the effects of a walk-and-eat intervention for patients with esophageal cancer undergoing neoadjuvant chemoradiotherapy. Participants with locally advanced esophageal cancer stage IIB or higher (n = 59) were randomly assigned to receive the walk-and-eat intervention (n = 30; nurse-supervised walking three times per week and weekly nutritional advice) or usual care (n = 29; control group) during 4-5 weeks of chemoradiotherapy. Primary endpoints were changes in distance on the 6-minute walk test, hand-grip strength, lean muscle mass, and body weight between initiation and completion of intervention. Participants (mean age: 59.6 years) were mostly male (92.9%) with squamous cell carcinoma (96.4%). During chemoradiotherapy, participants who received the walk-and-eat intervention had 100-m less decline than controls in walk distance (adjusted p = .012), 3-kg less decrease in hand-grip strength (adjusted p = .002), and 2.7-kg less reduction in body weight (adjusted p < .001), regardless of age. The intervention group also had significantly lower rates of need for intravenous nutritional support and wheelchair use. The nurse-led walk-and-eat intervention is feasible and effective to preserve functional walking capacity and nutritional status for patients with esophageal cancer undergoing neoadjuvant chemoradiotherapy. ©AlphaMed Press.

    EMP-1 was selected from a series of differential expressed genes obtained from cDNA microarray in the authors' lab. Epithelial membrane pnteiu-1 gene (EMP-1) was expressed 6 fold lower in esophageal cancer than in normal tissue. The authors further designed the experiment to study the effect of human EMP-1 gene on human esophageal cancer cell line in order to explain the function of this gene on the carcinogensis and progression esophageal cancer. EMP-1 gene was cloned into eukaryotic vector and transfected into the human esophageal cancer cell line. The transfection effect was qualified by Western blot and RT-PCR method. The cell growth curve was observed and the cell cycle was checked by FACS method. EMP-1 was transfected into EC9706 cell line and its expression was up-regulated. The cell growth is accelerated and expression of EMP-1 is linked to induction of S phase arrest. EMP-1 gene has some relationship with carcinogenesis of esophagus.

    The purpose of this study is to investigate the potential benefits of conformal radiotherapy (CRT) combined with a sequential volumetric-modulated arc therapy (VMAT) boost in the treatment of upper thoracic esophageal cancer. Ten patients with upper thoracic esophageal cancer previously treated with CRT plus a sequential VMAT boost plan were replanned with CRT plus an off-cord CRT boost plan and a full course of VMAT plan. Dosimetric parameters were compared. Results indicated that CRT plus off-cord CRT boost was inferior in planning target volume (PTV) coverage, as indicated by the volume covered by 93% (p = 0.05) and 95% (p = 0.02) of the prescription dose. The full course VMAT plan was superior in conformal index (CI) and conformation number (CN), and produced the highest protection for the spinal cord. CRT plus a VMAT boost demonstrated significant advantages in decreasing the volume of the lung irradiated by a dose of 10 Gy (V10, p = 0.007), 13 Gy (V13, p = 0.003), and 20 Gy (V20, p = 0.001). The full course VMAT plan demonstrated the lowest volume of lung receiving a dose of 30 Gy. CRT plus a VMAT boost for upper thoracic esophageal cancer can improve the target coverage and reduce the volume of lung irradiated by an intermediate dose. This combination may be a promising treatment technique for patients with upper thoracic esophageal cancer.

    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.

    Introduction Cancer of the esophagus is among the leading cause of cancer deaths in Punjab, India. Patients generally present with dysphagia as their first symptom and more often they have advanced disease at the time of presentation to a tertiary care centre. Palliative procedures have important roles in this setting. Stenting is the best option to palliate the symptoms of dysphagia, from which patient is suffering the most. Aim To know the success rate, early and long term complications and mortality in esophageal stenting, when it was done in malignant esophageal stricture patients. Materials and Methods One hundred patients, who had undergone esophageal stenting from January 2012 to January 2015, were included in the study. We retrospectively analysed the data for patient characteristics, causes of non-operability, early and long term complications, re-interventions, efficacy and mortality. Results Out of 100 patients, indications for stenting were locally advanced disease not amenable to surgery (52%), metastatic disease (35%), CVA (1%), cardiac and respiratory problem (8%), un-willing for surgery in 5% of patients. Majority of patients (94%) had squamous cell carcinoma, while only 6% had adenocarcinoma. 84% of patients presented with dysphagia with or without chest pain and recurrent cough while 16% had recurrent vomiting. 58% had dysphagia to liquids and solids and 17% had complete dysphagia. After stenting 93% had significant improvement in dysphagia score from median of 3 to 1. Post procedure stay was 3.61±1.0 days. One patient had procedure related major complication in the form of post procedural bleed (after 16 days of stenting) leading to death of that patient. Minor complications were present in 52 patients treated conservatively not affecting the efficacy of procedure. These include pain after stenting (38%), stent obstruction (23%) and stent migration (6%). All the minor complications were treated conservatively except in six patients in whom re

    Most published minimally invasive esophagectomy techniques involve a multiple field approach, including laparoscopic and thoracoscopic esophageal mobilization. Laparoscopic transhiatal esophagectomy (LTE) should potentially reduce the complications associated with thoracotomy. This study aims to compare outcomes of LTE with open transhiatal esophagectomy (OTE) and en-bloc esophagectomy (EBE). Retrospective chart review was performed on all patients who had an LTE for cancer between July 2008 and July 2012 at our institution. Data was compared with an historic cohort of patients who underwent OTE and EBE at the same institution from July 2002 to July 2008. There were 33 patients with LTE, compared with 60 patients with OTE and 139 with EBE. The presence of minor operative complications was similar (p = 0.36), but major complications were significantly less common in the LTE group (12, 23 and 33 %, respectively; p = 0.04). The median number of blood transfusions during hospitalization was significantly lower in the LTE group (0, 2.5 and 3, respectively; p = 0.005). Median tumor size was significantly smaller (1.5, 2.2, and 3 cm, respectively; p = 0.03), but the LTE group had a significantly higher percentage of patients with neoadjuvant treatment (39, 14 and 29 %, respectively; p = 0.008). Median lymph node yield for LTE was lower (24, 36 and 48, respectively; p < 0.0001), but the percentage of patients with positive nodes was similar (33, 33 and 39 %, respectively; p = 0.69). Mortality was equivalent among the groups (0, 2 and 4 %, respectively; p = 0.38). The median LOS for the LTE group was significantly lower (10, 13 and 15 days, respectively; p < 0.0001). Overall survival was not different between the three groups (p = 0.65), with median survival at 24 months of 70, 65 and 65 %, respectively. LTE can be performed safely with less major complications and shorter hospital stay than open esophagectomy. The reduced lymph-node harvest did

    Esophagitis is the second most common gastrointestinal manifestation of cytomegalovirus (CMV) infection after colitis. CMV esophagitis has been reported in patients who have undergone transplantation, are on long-term renal dialysis, or who have the human immunodeficiency virus infection. This study aimed to investigate the clinical characteristics and manifestations of CMV esophagitis in patients who underwent diagnostic endoscopy. A total of 16 patients with histologically proven CMV infection were identified from 1539 patients with esophageal ulcers and analyzed retrospectively (January 2006 to December 2013). Patients' personal data (age, smoking, and alcohol consumption), underlying systemic diseases (diabetes mellitus, end-stage renal disease, and chronic obstructive pulmonary disease), malignancy, indication for esophagogastroduodenoscopy, endoscopic characteristics, and diagnostic methods (pathological or serological findings) were collected for further analysis. Among the patients with CMV esophagitis, the mean age was 59.94 years (range, 23-84 years). The male : female ratio was 1.67:1. Odynophagia and epigastralgia were common symptoms. Of the 16 patients, 3 (18.75%) were infected with the human immunodeficiency virus and 9 (56.25%) had an underlying malignancy, including lung cancer (6 patients), esophageal cancer (2 patients), gastric cancer (1 patient), ampulla of Vater cancer (1 patient), and lymphoma (1 patient). Six of the 9 patients (66.7%) with malignancy had been administered concurrent chemoradiotherapy (CCRT). In this study, patients with malignancy who had been administered CCRT were at increased risk for CMV esophagitis, which had not been reported before in the literature. CMV esophagitis should be considered as a potential treatment-related complication of CCRT. © 2015 International Society for Diseases of the Esophagus.

    We examined the risk factors and prognostic factors for synchronous esophageal neoplasia (SEN) by comparing the characteristics of hypopharyngeal cancer (HPC) patients with and without SEN. We examined 183 patients who were treated with definitive radiotherapy for HPC. Lugol chromoendoscopy screening of the esophagus was performed in all patients before chemoradiotherapy. Thirty-six patients had SEN, 49 patients died of HPC and two died of esophageal cancer. The patients with SEN exhibited significantly higher alcohol consumption than those without SEN (P = 0.018). The 5-year overall survival (OS) rate of the 36 patients with SEN was lower than that of the other patients (36.2% vs 63.4%, P = 0.006). The SEN patients exhibited significantly shorter HPC cause-specific survival than the other patients (P = 0.039). Both the OS (P = 0.005) and the HPC cause-specific survival (P = 0.026) of the patients with SEN were significantly shorter than those of the patients without SEN in multivariate analysis. Category 4/T1 stage esophageal cancer was treated with concurrent chemoradiotherapy (CCRT), endoscopic treatment or chemotherapy. The 5-year survival rates for esophageal cancer recurrence for CCRT, endoscopic treatment and chemotherapy were 71.5, 43.7 and 0%, respectively. The median (range) survival time (months) of CCRT, endoscopic treatment and chemotherapy was 22.7 (7.5-90.6), 46.44 (17.3-136.7) and 7.98 (3.72-22.8), respectively. Advanced HPC patients with SEN might have a poorer prognosis than those without SEN even when the esophageal cancer is detected early and managed appropriately. © 2014 Wiley Publishing Asia Pty Ltd.

    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.

    Introduction We experienced two esophageal cancer patients who developed severe acute renal failure after neoadjuvant chemotherapy with cisplatin and 5-fluorourasil. Presentation of case After administration of cisplatin, their serum creatinine increased gradually until they required hemodialysis and their renal failure was permanent. In both cases, renal biopsy examination indicated partial recovery of the proximal tubule, but renal function did not recover. After these events, one patient underwent definitive radiotherapy and the other underwent esophagectomy for their esophageal cancers, while continuing dialysis. Both patients are alive without cancer recurrence. Discussion In these two cases of cisplatin-induced renal failure, renal biopsy examination showed only slight disorder of proximal tubules and tendency to recover. Conclusion Although cisplatin-related nephrotoxicity is a well-recognized complication, there have been few reports of renal failure requiring hemodialysis in cancer patients. In this report, we present their clinical courses and the pathological findings of cisplatin-related renal failure. PMID:26851395

    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.

    AIM: To study the cancer stem cell population in esophageal cancer cell lines KYSE-150 and TE-1 and identify whether the resulting stem-like spheroid cells display cancer stem cells and radiation resistance characteristics. METHODS: A serum-free medium (SFM) suspension was used to culture esophageal cancer stem cell lines and enrich the esophageal stem-like spheres. A reverse transcription polymerase chain reaction assay was used to detect stem cell gene expression in the spheroid cells. Radiosensitivity of stem-like spheres and parental cells were evaluated by clonogenic assays. Furthermore, different cells after different doses of irradiation were tested to evaluate the change in sphere formation, cell cycle and CD44+CD271+ expression of tumor stem-like spheroid cells using flow cytometry before and after irradiation. RESULTS: The cells were observed to generate an increased number of spheres in SFM with increasing cell passage. Radiation increased the rate of generation of stem-like spheres in both types of cells. The average survival fraction (SF2) of the cultured KYSE-150 compared with TE-1 stem-like spheres after 2 Gy of radiation was 0.81 ± 0.03 vs 0.87 ± 0.01 (P < 0.05), while the average SF2 of KYSE-150 compared with TE-1 parental cells was 0.69 ± 0.04 vs 0.80 ± 0.03, P < 0.05. In the esophageal parental cells, irradiation dose-dependently induced G2 arrest. Stem-like esophageal spheres were resistant to irradiation-induced G2 arrest without significant changes in the percentage population of irradiated stem-like cells. Under irradiation at 0, 4, and 8 Gy, the CD44+CD271+ cell percentage for KYSE150 parental cells was 1.08% ± 0.03% vs 1.29% ± 0.07% vs 1.11% ± 0.09%, respectively; the CD44+CD271+ cell percentage for TE1 parental cells was 1.16% ± 0.11% vs 0.97% ± 0.08% vs 1.45% ± 0.35%, respectively. The differences were not statistically significant. Under irradiation at 0, 4, and 8 Gy, the CD44+CD271+ cell percentage for KYSE-150 stem

    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.

    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.

    Tylosis esophageal cancer (TOC) is an autosomal-dominant syndrome characterized by palmoplantar keratoderma, oral precursor lesions, and a high lifetime risk of esophageal cancer. We have previously localized the TOC locus to a small genomic interval within chromosomal region 17q25. Using a targeted capture array and next-generation sequencing, we have now identified missense mutations (c.557T>C [p.Ile186Thr] and c.566C>T [p.Pro189Leu] in RHBDF2, which encodes the inactive rhomboid protease RHBDF2 (also known as iRhom2), as the underlying cause of TOC. We show that the distribution of RHBDF2 in tylotic skin is altered in comparison with that in normal skin, and immortalized tylotic keratinocytes have decreased levels of total epidermal growth factor receptor (EGFR) and display an increased proliferative and migratory potential relative to normal cells, even when normal cells are stimulated with exogenous epidermal growth factor. It would thus appear that EGFR signaling is dysregulated in tylotic cells. Furthermore, we also show an altered localization of RHBDF2 in both tylotic and sporadic squamous esophageal tumors. The elucidation of a role of RHBDF2 in growth-factor signaling in esophageal cancer will help to determine whether targeting this pathway in chemotherapy for this and other squamous cell carcinomas will be effective.

    Photodynamic therapy (PDT), which uses a light-sensitive compound and laser irradiation, is a light-based oncological treatment modality. PDT offers an alternative, less invasive treatment for various malignant tumors, such as esophageal cancer (EC), through a photochemical reaction induced by photofrin-II or other oncotropic photosensitizers without severe complications. Previous studies has shown that cancerous tissues accumulated more photosensitizers than paired normal tissues, however, whether it is cellular or vascular mechanisms remains unknown. Herein, in vivo and in vitro examinations were performed to study the mechanisms by which photofrin-II effectively and specifically killed EC cells. In this study, EC tissue of patients treated with photofrin-II, human ESCC cellline SHEEC and parental normal cellline SHEE, primary culture cells of EC tissue were used. The concentration of photofrin-II in cells were evaluated by high-performance liquid chromatography (HPLC). The results exhibited that accumulation of photofrin-II in cancerous cells were significantly higher than that in non-cancerous cells (p<0.05) under certain dose and time period of incubation of photofrin-II. In summary, our study showed that, photofrin-II specifically accumulated in EC cells in vivo and in vitro after controlling for vascular factors, which provided strong evidence that maybe the cellular factor is the main mechanism by which photofrin-II-mediated PDT selectively caused EC cells death.

    Purpose: To construct a model for the prediction of acute esophagitis in lung cancer patients receiving chemoradiotherapy by combining clinical data, treatment parameters, and genotyping profile. Patients and Methods: Data were available for 273 lung cancer patients treated with curative chemoradiotherapy. Clinical data included gender, age, World Health Organization performance score, nicotine use, diabetes, chronic disease, tumor type, tumor stage, lymph node stage, tumor location, and medical center. Treatment parameters included chemotherapy, surgery, radiotherapy technique, tumor dose, mean fractionation size, mean and maximal esophageal dose, and overall treatment time. A total of 332 genetic polymorphisms were considered in 112 candidate genes. The predicting model was achieved by lasso logistic regression for predictor selection, followed by classic logistic regression for unbiased estimation of the coefficients. Performance of the model was expressed as the area under the curve of the receiver operating characteristic and as the false-negative rate in the optimal point on the receiver operating characteristic curve. Results: A total of 110 patients (40%) developed acute esophagitis Grade {>=}2 (Common Terminology Criteria for Adverse Events v3.0). The final model contained chemotherapy treatment, lymph node stage, mean esophageal dose, gender, overall treatment time, radiotherapy technique, rs2302535 (EGFR), rs16930129 (ENG), rs1131877 (TRAF3), and rs2230528 (ITGB2). The area under the curve was 0.87, and the false-negative rate was 16%. Conclusion: Prediction of acute esophagitis can be improved by combining clinical, treatment, and genetic factors. A multicomponent prediction model for acute esophagitis with a sensitivity of 84% was constructed with two clinical parameters, four treatment parameters, and four genetic polymorphisms.

    Over the past decade, the imaging tools for endoscopists have improved drastically. This has enabled physicians to visually inspect the intestinal tissue for early signs of malignant lesions. Besides this, recent studies show the feasibility of supportive image analysis for endoscopists, but the analysis problem is typically approached as a segmentation task where binary ground truth is employed. In this study, we show that the detection of early cancerous tissue in the gastrointestinal tract cannot be approached as a binary segmentation problem and it is crucial and clinically relevant to involve multiple experts for annotating early lesions. By employing the so-called sweet spot for training purposes as a metric, a much better detection performance can be achieved. Furthermore, a multi-expert-based ground truth, i.e. a golden standard, enables an improved validation of the resulting delineations. For this purpose, besides the sweet spot we also propose another novel metric, the Jaccard Golden Standard (JIGS) that can handle multiple ground-truth annotations. Our experiments involving these new metrics and based on the golden standard show that the performance of a detection algorithm of early neoplastic lesions in Barrett's esophagus can be increased significantly, demonstrating a 10 percent point increase in the resulting F1 detection score.

    Esophageal cancer is one of the most unknown and deadliest cancers worldwide, mainly because of its extremely aggressive nature and poor survival rate. Esophageal cancer is the 6(th) leading cause of death from cancer and the 8(th) most common cancer in the world. The 5-year survival is around 15%-25%. There are clear differences between the risk factors of both histological types that affect their incidence and distribution worldwide. There are areas of high incidence of squamous cell carcinoma (some areas in China) that meet the requirements for cost-effectiveness of endoscopy for early diagnosis in the general population of those areas. In Europe and United States the predominant histologic subtype is adenocarcinoma. The role of early diagnosis of adenocarcinoma in Barrett's esophagus remains controversial. The differences in the therapeutic management of early esophageal carcinoma (high-grade dysplasia, T1a, T1b, N0) between different parts of the world may be explained by the number of cancers diagnosed at an early stage. In areas where the incidence is high (China and Japan among others) early diagnoses is more frequent and has led to the development of endoscopic techniques for definitive treatment that achieve very effective results with a minimum number of complications and preserving the functionality of the esophagus.

    Patients with upper third esophageal cancer or esophageal cancer with upper mediastinal paratracheal lymph node metastases are often precluded from surgery because of technical difficulties. With the aid of robotic surgery, an excellent overview and reach of the thoracic inlet can be accomplished. In this way, patients with upper mediastinal esophageal cancer are eligible for esophageal resection with curative intent. The aim of this study was to review the results of a consecutive series of patients who underwent robot-assisted minimally invasive esophagectomy (RAMIE) for tumors of the upper 1/3 of the esophagus or positive lymph nodes in the upper mediastinum. Between 2007-2016, 31 patients who underwent RAMIE in the UMC Utrecht for proximal esophageal cancer or proximal thoracic lymphadenopathy were identified from a prospective surgical database. Perioperative characteristics and oncologic outcomes were collected. The majority of patients had a squamous cell carcinoma. Clinical tumor stage was cT3 or higher in 25 (81%) of patients. Clinically positive lymph nodes (cN1-3) were observed in 29 (94%) patients. Neoadjuvant treatment was administered in 27 (87%) patients. Median duration of the surgical procedure was 435 min (range 299-874 min). Pulmonary complications were most frequent and occurred in 13 (42%) patients. Median intensive care (ICU stay) was 1 day (range 1-65 days) and median overall postoperative hospital stay was 15 days (range 10-118 days). In hospital mortality was 10%. Causes of mortality were tracheo-neo-esophageal fistula, sepsis after abdominal wall drainage due to leakage of the jejunal fistula resulting in respiratory and kidney failure, after which refraining further treatment resulting in death, and irreversible ARDS in a patient with COPD Gold III needing extracorporeal life support.

Methods Between 2007–2016, 31 patients who underwent RAMIE in the UMC Utrecht for proximal esophageal cancer or proximal thoracic lymphadenopathy were identified from a prospective surgical database. Perioperative characteristics and oncologic outcomes were collected. Results The majority of patients had a squamous cell carcinoma. Clinical tumor stage was cT3 or higher in 25 (81%) of patients. Clinically positive lymph nodes (cN1–3) were observed in 29 (94%) patients. Neoadjuvant treatment was administered in 27 (87%) patients. Median duration of the surgical procedure was 435 min (range 299–874 min). Pulmonary complications were most frequent and occurred in 13 (42%) patients. Median intensive care (ICU stay) was 1 day (range 1–65 days) and median overall postoperative hospital stay was 15 days (range 10–118 days). In hospital mortality was 10%. Causes of mortality were tracheo-neo-esophageal fistula, sepsis after abdominal wall drainage due to leakage of the jejunal fistula resulting in respiratory and kidney failure, after which refraining further treatment resulting in death, and irreversible ARDS in a patient with COPD Gold III needing extracorporeal life support. Radical resection was achieved in 30 (97%) of the patients. Median number of retrieved lymph nodes was 22 (range 9–57

    Patients with esophageal cancer often present with dysphagia and malnutrition. Obstructive symptoms may improve after radiotherapy and chemotherapy. Nutrition support via a nasogastric tube (NG) or gastrostomy is very important during treatment. The newly developed ultrathin endoscope (Olympus, GIF-N230, outer diameter: 6 mm) has a smaller diameter than the standard endoscope and can be introduced into the esophagus via the nasal cavity. This article reports on the use of an ultrathin endoscope for NG placement for patients with esophageal cancer who presented with dysphagia and failed traditional NG tube placement. A consecutive series of 40 patients with esophageal cancer were referred to our hospital from November 2001 to October 2002 for endoscopic placement of NG tubes due to failure of traditional methods of NG placement. An ultrathin endoscope was used to advance the guidewire into the stomach via the nasal cavity. After withdrawal of the scope, the NG tube was inserted over the guidewire under fluoroscopy. A total of 71 procedures were performed in 40 patients (37 males, 3 females), age 57 +/- 15 years (range, 37-91 y). Seventy procedures (99%) were successful in completing NG tube placement by using an ultrathin transnasal endoscope. Only one procedure failed because the esophageal lumen was completely occluded and the guidewire was not able to be passed through the obstructed site. The average duration that the NG tube was left in place was 49 +/- 35 days (range, 2-144 days). No procedure-related complications, such as bleeding or perforation, occurred. Using ultrathin transnasal endoscopy to place an NG tube for esophageal cancer patients is effective and safe. It simplifies the procedures and increases the success rate.

    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%, p<005). Multivariate analysis revealed that GLUT-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.

    We previously identified four novel cDNA fragments related to human esophageal cancer. One of the fragments was named esophageal cancer related gene 2 (ECRG2). We report here the molecular cloning, sequencing, and expression of the ECRG2 gene. The ECRG2 cDNA comprises a 258 bp nucleotide sequence which encodes for 85 amino acids with a predicted molecular weight of 9.2 kDa. Analysis of the protein sequence reveals the presence at the N terminus of a signal peptide followed by 56 amino acids with a significant degree of sequence similarity with the conserved Kazal domain which characterizes the serine protease inhibitor family. Pulse-chase experiments showed that ECRG2 protein was detected in both cell lysates and culture medium, indicating that the ECRG2 protein was extracellularly secreted after the post-translational cleavage. In vitro uPA/plasmin activity analysis showed the secreted ECRG2 protein inhibited the uPA/plasmin activity, indicating that ECRG2 may be a novel serine protease inhibitor. Northern blot analysis revealed the presence of the major band corresponding to a size of 569 kb throughout the fetal skin, thymus, esophagus, brain, lung, heart, stomach, liver, spleen, colon, kidney, testis, muscle, cholecyst tissues and adult esophageal mucosa, brain, thyroid tissue and mouth epithelia. However, ECRG2 gene was significantly down-regulated in primary esophageal cancer tissues. Taken together, these results indicate that ECRG2 is a novel member of the Kazal-type serine protease inhibitor family and may function as a tumor suppressor gene regulating the protease cascades during carcinogenesis and migration/invasion of esophageal cancer.

    Lymph node metastasis is the strongest prognostic factor in esophageal cancer patients who have undergone esophagectomy. The accurate diagnosis of lymph node metastasis is important, but the pre-operative diagnostic accuracy is poor. The intraoperative diagnosis based on histopathological examination of frozen tissue specimens is complicated and time-consuming. Therefore, the establishment of a simple and rapid intraoperative diagnostic method is essential. Exogenous application of 5-aminolevulinic acid (ALA) causes a selective accumulation of protoporphyrin IX, which is a fluorescent substrate, in cancer cells. The present study evaluated the feasibility of photodynamic diagnosis using ALA (ALA-PDD) for lymph node metastasis in esophageal cancer. A total of 292 lymph nodes were analyzed from 8 esophageal squamous cell cancer patients treated with esophagectomy. The patients were administered ALA orally prior to surgery. Excised lymph nodes were cut in half and examined by spectrometer. The diagnostic results of ALA-PDD were compared to those of the histopathological examination. Among the 292 lymph nodes, 19 nodes (6.5%) were histologically metastatic and 21 nodes (7.2%) were PDD-positive. The sensitivity and specificity of ALA-PDD were 84.2% (16/19) and 98.2% (268/273), respectively. The area of cancer nests of the PDD-negative lymph nodes was <2 mm2. Metastatic lymph nodes, including cancer nests >4 mm2, were correctly diagnosed by ALA-PDD. In conclusion, this study demonstrated that ALA-PDD of lymph node metastasis in patients with esophageal cancer is feasible. Further investigation would make this method a simple and rapid intraoperative diagnostic tool. PMID:26722285

    Background Childhood cancer survivors develop gastrointestinal malignancies more frequently and at a younger age than the general population, but risk factors for their development have not been well characterized. Objective To determine the risk and associated risk factors for gastrointestinal subsequent malignant neoplasms (SMN) in childhood cancer survivors. Design Retrospective cohort study. Setting The Childhood Cancer Survivor Study, a multi-center study of childhood cancer survivors diagnosed between 1970 and 1986. Patients 14,358 survivors of a malignancy diagnosed at < 21 years who had survived for 5 or more years from initial diagnosis. Measurements Standardized incidence ratios (SIR) for gastrointestinal SMN were calculated using age-specific population data. Multivariate Cox regression models identified associations between risk factors and gastrointestinal SMN development. Results At median follow-up of 22.8 years (range: 5.5-30.2), 45 gastrointestinal malignancies were identified. Gastrointestinal SMN risk was 4.6-fold higher in childhood cancer survivors than the general population (95% confidence interval [CI]: 3.5-6.1). Colorectal cancer SIR was 4.2 (95% CI: 2.8-6.3). The highest gastrointestinal SMN risk was associated with abdominal radiation (SIR=11.2, 95% CI: 7.6-16.4). However, survivors not exposed to radiation had a significantly increased risk (SIR=2.4, 95% CI-1.4-3.9). In addition to abdominal radiation, high dose procarbazine (RR=3.2, 95% CI 1.1-9.4) and platinum drugs (RR 7.6, 95% CI: 2.3-25.5) independently increased the gastrointestinal SMN risk. Limitations This cohort has not yet attained an age at which gastrointestinal malignancy risk is greatest. Conclusions Childhood cancer survivors, particularly those exposed to abdominal radiation, are at increased risk for gastrointestinal SMN. These findings suggest that surveillance of at-risk childhood cancer survivors should commence at a younger age than recommended for the general

    Since 2000, considerable progress has been made in health research in Iran. An example of this progress has been the Gastro- Esophageal Malignancies in Northern Iran (GEMINI). The original aim of this project was to identify etiologic factors and prevention measures for upper gastrointestinal cancers in Northern provinces of Iran, but its achievements have gone much beyond the initial goal. This project is one of the largest studies in the Middle East and North African region, has helped build and strengthen research capacity at both individual and institutional levels in Iran, and has provided international credibility to research institutes and the wider research system in Iran. The success of GEMINI reveals the feasibility of large-scale studies in developing countries and serves as a successful model not only for health research institutes within Iran, but also for research systems in other developing countries. The outcomes of the project are numerous, including establishment of research networks, development of efficient methods for planning and implementation of research projects, and introduction of methodologies for project management, data management and usage of health technology. Finally and perhaps most importantly, GEMINI is among the few projects that has had a significant impact on the attitudes and concerns of decision makers in the health sector in Iran. It signifies the importance of investment in human resources and has proved that health policies should be health-based rather than patient-based. Here we review the impact of GEMINI on the health research system and the broader health care system of Iran and put these into a more global perspective. PMID:23273237

    Onconephrology is an emerging medical subspecialty focused on the numerous interconnections between cancer and kidney diseases. Patient with malignancies commonly experience kidney problems including acute kidney injury, tumor lysis syndrome, fluid and electrolyte disorders and chronic kidney disease, often as a consequence of the anti-cancer treatment. Conversely, a number of glomerulopathies, tubulopathies and vascular renal diseases can early signal the presence of an underlying cancer. Furthermore, the administration of immunosuppressive drugs, especially cytotoxic drugs and calcineurin inhibitors, may strongly impair the immune response increasing the risk of cancer. The objective of this review article is to: (i) discuss paraneoplastic glomerular disease, (ii) review cancer as an adverse effect of immunosuppressive agents used to treat glomerulopathies, and (iii) in the absence of international approved guidelines, propose a screening program based on expert opinion aimed at guiding nephrologists to early detect malignancies during their clinical practice.

    Esophageal cancers account for majority of synchronous or metachronous head and neck cancers. This study examined the risk of esophageal cancer following percutaneous endoscopic gastrostomy (PEG) in head and neck cancer patients using the Taiwan National Health Insurance Research Database. From 1997 to 2010, we identified and analyzed 1851 PEG patients and 3702 sex-, age-, and index date-matched controls. After adjusting for esophagitis, esophagus stricture, esophageal reflux, and primary sites, the PEG cohort had a higher adjusted hazard ratio (2.31, 95% confidence interval [CI] = 1.09-4.09) of developing esophageal cancer than the controls. Primary tumors in the oropharynx, hypopharynx, and larynx were associated with higher incidence of esophageal cancer. The adjusted hazard ratios were 1.49 (95% CI = 1.01-1.88), 3.99 (95% CI = 2.76-4.98), and 1.98 (95% CI = 1.11-2.76), respectively. Head and neck cancer patients treated with PEG were associated with a higher risk of developing esophageal cancer, which could be fixed by surgically placed tubes.

    A strong association between inactive aldehyde dehydrogenase-2 (ALDH2) and risk of esophageal cancer has been demonstrated in East Asian drinkers. An alcohol flushing questionnaire asking about past and current tendency for facial flushing to occur after drinking a glass (≈180 mL) of beer predicts the presence of inactive ALDH2 among Japanese aged 40 years or older with a sensitivity and specificity of approximately 90%. We invented a health-risk appraisal (HRA) model that makes it possible to identify Japanese men who are at high risk for esophageal cancer based on their past and current alcohol flushing tendency, drinking, smoking, and intake of vegetables and fruits. Between 2008 and 2009, 2221 Japanese men aged 50 years or older filled out the HRA questionnaire before undergoing a screening examination by upper gastrointestinal endoscopy at five medical facilities. The endoscopic examination resulted in a diagnosis of esophageal cancer in 19 subjects, and 117 (5.27%) subjects had an HRA score ≥ 11. The proportion of subjects with an HRA score ≥ 11 was higher in the 50-69 age group (6.11-6.88%) than in 70-89 age group (2.84-2.86%). The esophageal cancer detection rate was 4.27% among the subjects with an HRA score ≥ 11 and only 0.67% among the other subjects. Based on a receiver operating characteristic curve analysis, when an HRA score of ≥ 9 was used for subjects aged 50-69 years and of ≥ 8 for those aged 70-89 years as the cutoff value to select individuals with a high risk for esophageal cancer, its sensitivity and false-positive rate was 52.6% and 15.2%, respectively, and the cancer detection rate was 2.91% in the high-risk group, as opposed to 0.48% in the other group. In conclusion, the high detection rates for esophageal cancer in the high-risk groups encouraged screening based on our HRA model in larger Japanese populations.

    Background: Nut consumption has been associated with decreased risk of colorectal, endometrial, lung, and pancreatic cancers. Polyphenols, fiber, vitamins, and minerals in nuts may confer this observed protective effect. To our knowledge, no prospective study has evaluated the effect of nut consumption on esophageal and gastric cancers.Objective: The objective was to evaluate the associations between nut and peanut butter consumption and the risk of esophageal and gastric cancers and their different subtypes.Design: In this study we used data from the NIH-AARP Diet and Health Study, which enrolled 566,407 persons who were 50-71 y old at baseline (1995-1996). The median follow-up time was 15.5 y. Intakes of nuts and peanut butter were assessed through the use of a validated food-frequency questionnaire. We used Cox proportional hazard models to estimate HRs and 95% CIs for esophageal and gastric cancers and their subtypes.Results: We identified 966 incident cases of esophageal adenocarcinomas, 323 cases of esophageal squamous cell carcinoma, 698 cases of gastric cardia adenocarcinoma, and 732 cases of gastric noncardia adenocarcinoma. Compared with those who did not consume nuts or peanut butter [lowest category of consumption (C0)], participants in the highest category of nut consumption (C3) had a lower risk of developing gastric noncardia adenocarcinoma [C3 compared with C0, HR: 0.73 (95% CI: 0.57, 0.94)]. This inverse association was also seen for peanut butter consumption [C3 compared with C0, HR: 0.75 (95% CI: 0.60, 0.94)]. We observed no significant associations between the highest and lowest intakes of nuts or peanut butter and the risk of gastric cardia adenocarcinoma, esophageal adenocarcinoma, or esophageal squamous cell carcinoma.Conclusions: Among older American adults, both nut and peanut butter consumption were inversely associated with the risk of gastric noncardia adenocarcinoma. This trial was registered at clinicaltrials.gov as NCT00340015.

    The esophageal cancer has a tendency to transfer to another part of the body and the surgical operation itself sometimes gives high risk in vital function because many delicate organs exist near the esophagus. So the esophageal cancer is a disease with a high mortality. So, in order to lead a higher survival rate five years after the cancer's treatment, the investigation of the diagnosis methods or techniques of the cancer in an early stage and support the therapy are required. In this study, we performed the ex vivo experiments to obtain the Raman spectra from normal and early-stage tumor (stage-0) human esophageal sample by using Raman spectroscopy. The Raman spectra are collected by the homemade Raman spectrometer with the wavelength of 785 nm and Raman probe with 600-um-diameter. The principal component analysis (PCA) is performed after collection of spectra to recognize which materials changed in normal part and cancerous pert. After that, the linear discriminant analysis (LDA) is performed to predict the tissue type. The result of PCA indicates that the tumor tissue is associated with a decrease in tryptophan concentration. Furthermore, we can predict the tissue type with 80% accuracy by LDA which model is made by tryptophan bands.

    Cytokeratins are thought to play a role in apoptosis. Cytokeratin 18 (CK18) is involved in the formation of intracellular cytoskeleton, and has been considered a promising apoptosis marker in gastrointestinal carcinomas. Growth factors, including hepatocyte growth factor (HGF), may provide a microenvironment for malignant cells. In this study, we aimed to compare serum HGF and CK18 levels between esophageal squamous cell carcinoma patients and healthy controls. The study included 41 adult patients (20 male, 21 female) diagnosed with esophageal squamous cell carcinoma, with a mean age of 63.54 ± 10.88 years (range, 41-82 years). We also recruited 39 age and gender-matched healthy control subjects. Venous blood samples were taken; serum HGF and CK18 concentrations were determined via ELISA. Results indicated that serum HGF levels were higher in patients (1.37 ± 0.63 ng/mL) as compared to the healthy subjects (0.41 ± 0.29 ng/mL). Similarly, serum CK18 levels were higher in the patient group (2.53 ± 1.33 ng/mL) than in the control group (0.34 ± 0.23 ng/mL) (P < 0.001). In addition, serum HGF and CK18 levels were positively correlated with metastasis stage, tumor stage, and disease stage of esophageal squamous cell carcinoma. To our knowledge, this is the first study to evaluate serum HGF and CK18 levels in patients with esophageal squamous cell carcinoma. The results suggest that serum CK18 and HGF levels may be used as prognostic and disease monitoring biomarkers of esophageal squamous cell carcinoma.

    A 48-year-old female who presented with a history of dysphagia for 5 months and regurgitation for 1 week was referred to the Sir Run Run Shaw Hospital (Hangzhou, China) for further evaluation, since the gastroscopy and endoscopic ultrasound performed in local hospitals did not reveal the presence of cancer. High-resolution manometry (HRM) of the esophagus was performed to determine the patient's condition, and revealed an abnormal high-pressure zone that was located 33 cm from the incisor and did not relax upon swallowing. Synchronous waves were observed, and the pressure of the esophageal lumen was found to increase with secondary synchronous peristaltic waves. The lower esophageal sphincter was 39 cm from the incisor and relaxed upon swallowing. The abnormal high-pressure zone could have been caused by an obstruction, and therefore an upper gastrointestinal series (barium swallow) test and gastroscopy were recommended to further pinpoint the cause. Following the two examinations, mid-esophageal cancer was considered as a possible diagnosis. A biopsy was performed and the final diagnosis was that of basaloid squamous cell carcinoma. The findings of the present study suggest that, for patients with evident symptoms of esophageal motor dysfunction without significant gastroscopy findings, HRM is recommended. PMID:27123076

    Breast Cancer is one of the most deadly cancers affecting middle-aged women. Accurate diagnosis and prognosis are crucial to reduce the high death rate. Nowadays there are numerous diagnostic tools for breast cancer diagnosis. In this paper we discuss a role of nuclear segmentation from fine needle aspiration biopsy (FNA) slides and its influence on malignancy classification. Classification of malignancy plays a very important role during the diagnosis process of breast cancer. Out of all cancer diagnostic tools, FNA slides provide the most valuable information about the cancer malignancy grade which helps to choose an appropriate treatment. This process involves assessing numerous nuclear features and therefore precise segmentation of nuclei is very important. In this work we compare three powerful segmentation approaches and test their impact on the classification of breast cancer malignancy. The studied approaches involve level set segmentation, fuzzy c-means segmentation and textural segmentation based on co-occurrence matrix. Segmented nuclei were used to extract nuclear features for malignancy classification. For classification purposes four different classifiers were trained and tested with previously extracted features. The compared classifiers are Multilayer Perceptron (MLP), Self-Organizing Maps (SOM), Principal Component-based Neural Network (PCA) and Support Vector Machines (SVM). The presented results show that level set segmentation yields the best results over the three compared approaches and leads to a good feature extraction with a lowest average error rate of 6.51% over four different classifiers. The best performance was recorded for multilayer perceptron with an error rate of 3.07% using fuzzy c-means segmentation.

    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. PMID:28223720

    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.

    Malignant melanoma represents a neoplasm stemming from melanocytes or the cells that develop from melanocytes. Melanocytes, pigment-producing cells, arise from the neural crest and migrate to their final destinations in the skin, uveal tract, meninges, and mucosa. Most melanocytes are found at the epidermal-dermal junction of the skin, and the vast majority of melanocytes arise from cutaneous sites. Cancerous growths develop when unrepaired DNA damage to skin cells (most often caused by ultraviolet radiation from sunshine or tanning beds) triggers mutations (genetic defects) that lead the skin cells to multiply rapidly and form malignant tumours. Malignant tumours consist of heterogeneous populations of tumour cells. Cancer stem cells (CSC) represent a population of cells within a tumour with highly tumorigenic and chemoresistant properties. These cells may be identified by the expression of CSC markers and also by functional assays as tumour-initiating properties in vivo, high aldehyde dehydrogenase activity tested by Aldefluor assay. There are several key stem cells markers specified for malignant melanoma: CD20, CD133, ABCB5, CD271 and ALDH1A. The review provides a detailed overview of risk factors, diagnosis, treatment possibilities and specific properties of cancer stem cells in malignant melanoma.

    In the Department of Pathology of Albert Szent-Györgyi Medical University at Szeged in Hungary 37,504 autopsies were performed in the last 30 years and double multiple primary malignant tumours were found in 385 cases (4.2%). In thyroid cancer cases the tumours of other organs were more frequent (22.7%), and these tumour-associations were observed mainly simultaneously, there were no important sex differences. In the most of cases the thyroid cancer was only a side diagnosis beside other malignancies, in the more rare metachronous cases the thyroid cancer was secondary following postoperative irradiation of the first tumour (4 cases of 5). We have seen thyroid cancers most frequently together with lung, breast and digestive system tumours.

    Esophageal cancer is a disease with high mortality. In order to improve the 5 year survival rate after cancer treatment, it is important to develop a method for early detection of the cancer and for therapy support. There is increasing evidence that Raman spectroscopy, in combination with chemometric analysis, is a powerful technique for discriminating pre-cancerous and cancerous biochemical changes. In the present study, we used Raman spectroscopy to examine early-stage (stages 0 and I) esophageal cancer samples ex vivo. Comparison between the Raman spectra of cancerous and normal samples using a t-test showed decreased concentrations of glycogen, collagen, and tryptophan in cancerous tissue. Partial least squares regression (PLSR) analysis and self-organization maps (SOMs) discriminated the datasets of cancerous and normal samples into two groups, but there was a relatively large overlap between them. Linear discriminant analysis (LDA) based on Raman bands found in the t-test was able to predict the tissue types with 81.0% sensitivity and 94.0% specificity.

    Purpose: To quantify the interfraction displacement of esophageal fiducial markers for primary esophageal cancer radiation therapy. Methods and Materials: Orthogonal 2-dimensional (2D) matching records fused to vertebrae were analyzed in clinically staged T1/2N0 esophageal cancer patients undergoing endoscopic clipping as fiducial metal markers. Displacement of the markers between the digitally reconstructed radiographs and on-board kilovoltage images during radiation therapy was analyzed according to direction and esophageal site. Results: Forty-four patients, with 81 markers (10 proximal, 42 middle, and 29 distal), underwent 367 2D matching sessions during radiation therapy. The mean (SD) absolute marker displacement was 0.26 (0.30) cm in the right–left (RL), 0.50 (0.39) cm in the superior–inferior (SI), and 0.24 (0.21) cm in the anterior–posterior (AP) direction. Displacement was significantly larger in the SI than in the RL and AP directions (P<.0001). In the SI direction, mean absolute displacements of the distal, middle, and proximal esophagus were 0.67 (0.45) cm, 0.42 (0.32) cm, and 0.36 (0.30) cm, respectively. Distal esophagus displacement was significantly larger than those of the middle and proximal esophagus (P<.0001). The estimated internal margin to cover 95% of the cases was 0.75 cm in the RL and AP directions. In the SI direction, the margin was 1.25 cm for the proximal and middle esophagus and 1.75 cm for the distal esophagus. Conclusions: The magnitude of interfraction displacement of esophageal clips was larger in the SI direction, particularly in the distal esophagus, but substantial displacement was observed in other directions and at other esophageal sites. It is practical to take estimated movements into account with internal margins, even if vertebrae-based 2D matching is performed.

    Chemoradiation therapy is widely used to treat both inoperable and operable patients, and is less invasive than surgery. Although the number of long-term survivors who have received chemoradiation therapy is increasing, the long-term toxicity pattern and cumulative incidence of toxicity regarding this modality are poorly understood. Classically, chemoradiation therapy for esophageal cancer consists of an anterior–posterior field and a subsequent oblique boost field. We retrospectively analyzed patients who were treated with definitive chemoradiation therapy for esophageal cancer using this classical method from 1999 to 2008. For the assessment of toxicity, the National Cancer Institute Common Toxicity Criteria Version 3.0 was adopted. A total of 101 patients were analyzed. The median follow-up time was 16 months for all patients and 62 months for the surviving patients. Eleven patients experienced late toxicities of ≥Grade 3. Two patients died of late toxicities. The 3- and 5-year cumulative incidences for the first late cardiopulmonary toxicities of ≥Grade 3 were 17.4% and 20.8%, respectively. Cardiopulmonary effusions were observed within the first 3 years of completion of the initial treatment in seven out of eight patients. Sudden death and cardiac ischemia were observed over a 10-year period. Older age was found to be a risk factor for late toxicity after definitive chemoradiation therapy for esophageal cancer. Substantial toxicities were observed in patients who had received chemoradiation therapy for esophageal cancer using the classical method. To minimize the incidence of late toxicity, more sophisticated radiation techniques may be useful. PMID:27475126

    Based on its marked overexpression in multiple malignancies and its roles in promoting cell survival and proliferation, survivin is an attractive candidate for targeted therapy. Towards this end, a detailed understanding of the mechanisms regulating survivin expression in different cancer cells will be critical. We have previously shown that the RNA-binding protein (RBP) CUG-BP1 is overexpressed in esophageal cancer cells and post-transcriptionally regulates survivin in these cells. The objective of this study was to investigate the role of microRNAs (miRs) in regulating survivin expression in esophageal cancer cells. Using miR expression profiling analysis, we found that miR-214-3p is one of the most markedly downregulated miRs in two esophageal squamous cancer cell lines compared to esophageal epithelial cells. Interestingly, using miR target prediction programs, both survivin and CUG-BP1 mRNA were found to contain potential binding sites for miR-214-3p. Forced expression of miR-214-3p in esophageal cancer cells leads to a decrease in the mRNA and protein levels of both survivin and CUG-BP1. This effect is due to decreased mRNA stability of both targets. By contrast, silencing miR-214-3p in esophageal epithelial cells leads to an increase in both survivin and CUG-BP1 mRNA and protein. To determine whether the observed effect of miR-214-3p on survivin expression was direct, mediated through CUG-BP1, or both, binding studies utilizing biotin pull-down assays and heterologous luciferase reporter constructs were performed. These demonstrated that the mRNA of survivin and CUG-BP1 each contain two functional miR-214-3p binding sites as confirmed by mutational analysis. Finally, forced expression of miR-214-3p enhances the sensitivity of esophageal cancer cells to Cisplatin-induced apoptosis. This effect is abrogated with rescue expression of survivin or CUG-BP1. These findings suggest that miR-214-3p acts as a tumor suppressor and that its downregulation contributes to

    Esophageal squamous cell cancer (ESCC) is an aggressive malignancy with poor survival. Long non-coding RNAs (lncRNAs) play important roles in tumorigenesis and cancer progression; hence, lncRNAs are also involved in the development and progression of ESCC. In this study, we used quantitative real-time polymerase chain reaction (qRT-PCR) to investigate expression of lncRNA, maternally expressed gene 3 (MEG3) in ESCC. Ectopic expression of MEG3 was performed in ESCC cell lines. Proliferation and apoptosis of ESCC cell lines were analyzed after ectopic expression of MEG3. We found MEG3 was significantly downregulated in ESCC tissues compared with normal tissues by qRT-PCR. Low expression of MEG3 was correlated with lymph node metastasis and advanced TNM stages of ESCC patients and indicated shorter survival (HR = 0.471, 95 % CI 0.234-0.950, P = 0.035), which was confirmed by The Cancer Genome Atlas (TCGA) esophageal cancer dataset. DNA-demethylating agent (5-aza-2-deoxy-cytidine (5-aza-CdR)) treatment significantly increased MEG3 expression level in ESCC cells, and TCGA esophageal cancer dataset also showed that DNA methylation of MEG3 predicted survival. Ectopic expression of MEG3 in ESCC cells inhibited cell proliferation, promoted apoptosis, and suppressed metastasis. Further investigation showed enforced expression of MEG3 activated p53 and its target genes by downregulation of mouse double minute 2 homolog (MDM2). Overall, our study indicated that MEG3 expression loss is common in ESCC and MEG3 could activate p53 and predict prognosis in ESCC.

    Patients with head/neck or esophageal (HNE) cancer are likely to develop malnutrition throughout the course of their disease and its treatment. Although nutrition care is considered a cornerstone of disease management, clinical practices to treat malnutrition vary. The objective of this qualitative study is to understand the patients' experiences with nutrition care in the context of their treatment and recovery. A descriptive qualitative study design was used to explore patients' experiences. Ten patients with head and neck (HN) cancer and 10 patients with esophageal cancer were interviewed near the completion of their cancer treatment using a semistructured interview guide. The data sets were analyzed separately using qualitative content analysis. The preliminary findings from each data set were compared and contrasted; 3 themes that crossed both data sets were identified. Three themes were identified: (1) coping with physical and psychosocial aspects of illness and nutrition; (2) understanding the nature of the illness, treatment, and nutrition pathway; and (3) being supported during the trajectory of care. The major differences between HN and esophageal groups were identified in the context of understanding and being supported: the lack of coordination throughout the trajectory of care and conflicting messages from healthcare providers were a source of uncertainty, confusion, and isolation in the HN group. The need for timely and ongoing patient-focused nutrition care, with formal and informal support, was identified in both groups. Models for nutrition care should support provision of consistent information across health professionals and throughout the treatment trajectory.

    The aim of the study was to collect the available data on central nervous system (CNS) metastases from esophageal and gastric cancer. A PubMed, EMBASE, SCOPUS, Web of Science, LILACS, Ovid and Cochrane Library search was performed. Thirty-seven studies including 779 patients were considered. Among the data extracted, treatment of tumor and brain metastases (BMs), time to BMs development, number and subsite, extracerebral metastases rate, median overall survival (OS) and prognostic factors were included. For esophageal cancer, the median OS from diagnosis of BMs was 4.2 months. Prognostic factors for OS included: performance status, multimodal therapy, adjuvant chemotherapy, single BM, brain only disease and surgery. For gastric cancer, median OS was 2.4 months. Prognostic factors for OS included: recursive partitioning analysis class 2, stereotactic radiosurgery (SRT) and use of intrathecal therapy. HER2-positive gastric cancer was shown to be associated with a higher risk and shorter time to CNS relapse. Patients harboring BMs from gastric and esophageal tumors, except cases with single lesions that are treated aggressively, have a poor prognosis. SRT (plus or minus surgery and whole brain radiotherapy) seems to give better results in terms of longer OS after brain relapse.

The value of screening endoscopy in evaluating these types of cancers is a critical area of discussion due to a potential reduction in morbidity and mortality. This article describes how to identify a good screening test and explains what are important criteria in the field of screening endoscopy. Furthermore, the current status and progress of screening endoscopy for esophageal, gastric, and colorectal cancer will be evaluated and discussed. Mass screening programs have not been implemented for esophageal and gastric carcinomas in those with average or low risk populations. However, studies of high-risk populations have found value and a cost-benefit in conducting screening endoscopy. Colorectal cancer, on the other hand, has had mass screening programs in place for many years due to the clear evidence of improved outcomes. As the role of endoscopy as a screening tool has continued to develop, newer technology and techniques have emerged to improve its utility. Many new image enhancement techniques and computer processing programs have shown promise and may have a significant role in the future of endoscopic screening. These developments are paving the way for improving the diagnostic and therapeutic capability of endoscopy in the field of gastroenterology. PMID:26361416

    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 < 0.001) and 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.

    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.

    To determine the safety and therapeutic effects of nimotuzumab (h-R3) combined with radiotherapy in esophageal cancer. This Phase II clinical trial involved 42 patients with stage II (inoperable or refused surgery) to stage IV (supraclavicular lymph node metastasis only) esophageal cancers treated between November 2008 and July 2010. All patients had squamous cell carcinomas, and all received three-dimensional conformal radiotherapy and 200 mg nimotuzumab per week during radiotherapy. There were 9, 25, and 8 patients with stage II, III and IV disease, respectively. All except two patients received 50-70 Gy radiation; 37 patients (88.1%) received more than five nimotuzumab doses. Grade III toxicities (21.4% of all adverse events) included esophagitis and gastrointestinal, dermatological and hematological toxicities. Complete response, partial response, stable disease, and progressive disease were observed in 0, 22 (52.4%), 17 (40.5%) and 3 (7.1%) patients at 1 month after the treatment. The epidermal growth factor receptor (EGFR) overexpression rate was 95.2%. After a median follow-up of 37 months, the median survival time (MST) was 14 months. The 2 year and 3 year overall survival (OS) rates were 33.3% and 26.2%, respectively. The median progression-free survival (PFS) time was 10 months. The 2 year and 3 year PFS rates were 24.5% and 22.1%, respectively. The MST in the 13 patients with (+++) EGFR expression (group A) and 7 patients with (++) EGFR expression (group B) was 15 and 11 months, respectively. The 2 year and 3 year OS rates were 46.2% and 38.5% in group A and 28.6% and 28.6% in group B, respectively (P = 0.405). Although concurrent chemoradiotherapy was the standard care for locally advanced esophageal cancer, radiotherapy was the choice for those who were refused or could not tolerate chemoradiotherapy. Our study shows that nimotuzumab combined with radiotherapy was well tolerated in patients with esophageal cancer. EGFR overexpression was more common

    Previously reported findings on the association between folate intake or serum folate levels and esophageal cancer risk have been inconsistent. This study aims to summarize the evidence regarding these relationships using a dose-response meta-analysis approach. We performed electronic searches of the Pubmed, Medline and Cochrane Library electronic databases to identify studies examining the effect of folate on the risk of esophageal cancer. Ultimately, 19 studies were included in the meta-analysis. Summary odds ratios (ORs) were estimated using a random effects model. A linear regression analysis of the natural logarithm of the OR was carried out to assess the possible dose-response relationship between folate intake and esophageal cancer risk. The pooled ORs for esophageal cancer in the highest vs. lowest levels of dietary folate intake and serum folate were 0.63 (95% CI: 0.56-0.71) and 0.71 (95% CI: 0.55-0.92), respectively. The dose-response meta-analysis indicated that a 100 μg/day increment in dietary folate intake reduced the estimate risk of esophageal cancer by 12%. These findings suggest that dietary and serum folate exert a protective effect against esophageal carcinogenesis.

    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.

    Expression analysis of MKK6 protein in solid tumors has never been investigated. Here, we report systematic analysis of MKK6 protein in different types of human tumor samples using western blotting and immunofluorescence techniques. We observed significant increase in the expression of MKK6 in Esophageal, Stomach, and Colon cancers as compared to controls. Results were alternately confirmed by Immunofluorescence studies. Upregulation of MKK6 protein is indicative of its role in human cancers and could possibly be used as a novel diagnostic or prognostic marker in these cancers.

    A 68-year-old woman was diagnosed with advanced esophageal cancer with lymph node metastasis, for which she received neoadjuvant chemoradiotherapy. During therapy, she had loss of appetite and weight; therefore, we inserted a nasal feeding tube for her nutrition, after which, she gained weight soon. After therapy, she had a high fever with lymphocytopenia and was diagnosed with cytomegalovirus infection because of significantly high CMV antigenemia. Ganciclovir was administered immediately, and she recovered soon. Two months later, we performed esophagectomy, and she recovered without complications. Immediate diagnosis of CMV infection, ganciclovir administration, and nutrition through a feeding tube were useful for the esophageal cancer patient in this report who had immunosuppression and malnutrition during chemoradiation.

    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.

    Eosinophilic esophagitis is increasingly recognized in adults. The diagnosis is based on the presence of both typical symptoms and pathologic findings on esophageal biopsy. Patients usually present with dysphagia, food impaction and/or reflux-like symptoms, and biopsy of the esophagus shows more than 15 eosinophils per high-power field. In addition, it is essential to exclude the presence of known causes of tissue eosinophilia such as gastroesophageal reflux disease, infections, malignancy, collagen vascular diseases, hypersensitivity, and inflammatory bowel disease. There are no standardized protocols for the therapy of eosinophilic esophagitis. A variety of therapeutic approaches including acid suppression, dietary modifications, topical corticosteroids and endoscopic dilation can be used alone or in combination. PMID:19115464

    Mycotoxins that commonly contaminate staple food grains pose a health hazard to animals and humans. Fumonisin B1 (FB1), a mycotoxin produced by Fusarium verticillioides, causes equine leukoencephalomalacia and porcine pulmonary edema and has been implicated in the etiology of esophageal cancer (EC) in the Transkei, South Africa. Various studies have indicated that nitrosamines induce EC, and F. verticillioides enhancement of nitrosamine-induced EC in rats has been reported. Dietary catechol (CAT), a constituent of cigarette smoke, was previously found to be a cocarcinogen with methyl-N-nitrosamine for inducing esophageal tumors in rats. In the present study we therefore investigated the cytotoxic effects of FB1, diethylnitrosamine (DEN), and CAT on a human esophageal epithelial cell line (SNO) using the methylthiazol tetrazolium assay. For each treatment, toxin concentrations ranged from 2.165 to 34.64 micro M. The results showed that the cytotoxic response of SNO cells was highest in cells treated with 34.64 micro M FB1. SNO cells treated with DEN + FB1 showed greater cytotoxicity than did cells treated with FB1 alone, whereas FB1 appeared to inhibit the cytotoxic effect exerted by CAT alone. The results of this study provide further evidence for the involvement of FB1 in the etiology of esophageal carcinoma. PMID:12153764

    Esophageal squamous cell carcinoma (ESCC) is an aggressive tumor that is typically diagnosed only when the tumor has gained remarkable size, extended to peripheral tissues, and led to dysphagia. Five-year survival of advanced cancer is still very poor (19%), even with improved surgical techniques and adjuvant chemoradiation therapy. Therefore, early detection and prevention are the most important strategies to reduce the burden of ESCC. Our review will focus on the studies conducted in Golestan province, an area with a high prevalence of ESCC in northern Iran. We review three aspects of the research literature on ESCC: epidemiological features, environmental factors (including substance abuse, environmental contaminants, dietary factors, and human papillomavirus [HPV]), and molecular factors (including oncogenes, tumor suppressor genes, cell cycle regulatory proteins, and other relevant biomarkers). Epidemiological and experimental data suggest that some chemicals and lifestyle factors, including polycyclic aromatic hydrocarbons (PAHs), cigarette smoking, opium use, and hot tea drinking are associated with the development of ESCC in Golestan. HPV infects the esophageal epithelium, but so far, no firm evidence of its involvement in esophageal carcinogenesis has been provided. Some of these factors, notably hot tea drinking, may render the esophageal mucosa more susceptible to injury by other carcinogens. There are few studies at molecular level on ESCC in Golestan. Increasing awareness about the known risk factors of ESCC could potentially reduce the burden of ESCC in the region. Further studies on risk factors, identifying high risk populations, and early detection are needed. PMID:27957288

    Esophageal cancer mortality is increased in African Americans relative to white patients. The reasons for this are unknown but are thought to be related to inadequate access to health care secondary to a higher poverty rate in African American populations. The National Health Interview Survey database for years 1986 to 1994 were combined and linked to the National Death Index. Individuals who died from esophageal carcinoma were assessed in the combined database, thus enabling detailed analysis of their socioeconomic status, race, and health care access. Poverty was 4-fold more frequent in African Americans who died from esophageal carcinoma than whites. Despite poverty, African American patients' access to health care was good and was not statistically related to increased mortality. Although the esophageal carcinoma mortality rate is higher in African Americans than in whites, it is not clearly related to the presence of poverty or to limited health care access. The higher mortality may be related to lifestyle differences, environmental exposure, or difference in disease biology, but it is not related exclusively to socioeconomic factors.

    PR domain is responsible for the tumor suppressing activity of RIZ1. The study aimed to construct human PR domain eukaryotic expression vectors, transfect human esophageal cancer cells (TE13), and evaluate the anticancer activity of PR domain on human esophageal cancer TE13 cells. First, mRNA was extracted from human esophageal cancer tissue by RT-PCR, then reverse-transcribed to cDNA. After amplifying from the DNA template, PR domain was linked to T vector. Second, after extraction, PR domain was cut using enzyme and linked to pcDNA3.1(+). Then, the plasmid was transfered to Trans1-T1 phage resistant competent cells, following by extracting the ultrapure plasmid, and transfecting into TE13 cells. In the end, the protein expression of pcDNA3.1(+)/PR domain in TE13 was detected by Western blot, and the apoptosis of TE13 by technique of flow cytometry. More than 5,000 bp purposed band of pcDNA3.1(+)/PR domain plasmid was found by agarose gel electrophoresis. After transfection, the PR domain (molecular weight of about 28 Da) was found only in 3, 4 and 5 groups by Western blot. Flow cytometry assay showed apoptosis in experimental group was significantly more than that in the control group (P<0.05). The PR domain eukaryotic expression vector was constructed successfully. The protein of the PR domain could be expressed in esophageal cancer TE13 cells firmly after transfection, and a single PR domain could promote apoptosis of TE13 cells.

    This study is aimed to assess the long-term health-related quality of life (HRQL) of patients after esophagectomy for esophageal cancer in comparison with es-tablished 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 OES18 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

    The role of proton pump inhibitors in Barrett's metaplasia and esophageal adenocarcinoma has been an area of controversy. We evaluated the effectiveness of the proton pump inhibitor rabeprazole as a chemoprevention agent in a surgical rat reflux model of esophageal cancer. The rat reflux model was created by performing a jejuno-esophagostomy on Sprague-Dawley rats. The surgery promoted the reflux of gastro-duodenal contents into the esophagus. Rabeprazole sodium (Eisai, Tokyo, Japan) was dissolved in 0.9% physiological saline to a desired concentration of 1.5% (W/V). Beginning 4 weeks post-surgery, all animals were administered either 0.2 ml per 100 g body weight injections of rabeprazole or equivalent injections of saline 3 days per week into the subcutaneous tissue of the back. Forty animals were killed 40 weeks after surgery and their esophagi were examined. Of these, 23 were included in the control group, while the remaining 17 were subjected to rabeprazole. While 74% (17/23) of the controls developed esophageal cancer, animals administered rabeprazole had an incidence of cancer of 29% (5/17) (p < 0.05, Fisher's exact test). Barrett's metaplasia was found on 100% (23/23) of the rats in the placebo group, but there was a protective effect in the rabeprazole group with 65% (11/17) of the rats displaying signs of Barrett's metaplasia (p < 0.05, Fisher's exact test). All of the rats developed proliferative hyperplasia. Rabeprazole protected against the development of esophageal cancer in a clinically relevant surgical reflux model. Rabeprazole warrants further investigation for potential clinical use as a chemoprevention agent.

    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.

    Esophageal cancer is the sixth leading cause of cancer mortality. More than 90% of patients with esophageal cancer in Taiwan have squamous cell carcinoma. Survival of such patients is related to socioeconomic status (SES). We studied the association between SES (individual and neighborhood) and the survival of working-age patients with esophageal cancer in Taiwan. A population-based study was conducted of 4097 patients diagnosed with esophageal cancer between 2002 and 2006. Each was traced for 5 years or until death. Individual SES was defined by enrollee job category. Neighborhood SES was based on household income and dichotomized into advantaged or disadvantaged. Multilevel logistic regression was used to compare the survival rates by SES group after adjustment for possible confounding and risk factors. Hospital and neighborhood SES were used as random effects in multilevel logistic regression. In patients younger than 65 years, 5-year overall survival rates were worst for those with low individual SES living in disadvantaged neighborhoods. After adjustment for patient characteristics, esophageal cancer patients with high individual SES had a 39% lower risk of mortality than those with low individual SES (odds ratio 0.61, 95% confidence interval 0.48-0.77). Patients living in disadvantaged areas with high individual SES were more likely to receive surgery than those with low SES (odds ratio 1.45, 95% confidence interval 1.11-1.89). Esophageal cancer patients with low individual SES have the worst 5-year survival, even with a universal healthcare system. Public health, education, and social welfare programs should address the inequality of esophageal cancer survival.

    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.

    This study aims to establish the prevalence and predictors of anxiety and depression among esophageal cancer patients, post-diagnosis but prior to curatively intended surgery. This was a cross-sectional study using data from a hospital-based prospective cohort study, carried out at St Thomas' Hospital, London. Potential predictor variables were retrieved from medical charts and self-report questionnaires. Anxiety and depression were measured prior to esophageal cancer surgery, using the Hospital Anxiety and Depression Scale. Prevalence of anxiety and depression was calculated using the established cutoff (scores ≥8 on each subscale) indicating cases of 'possible-probable' anxiety or depression, and multivariable logistic regression analyses were performed to examine predictors of emotional distress. Among the 106 included patients, 36 (34%) scored above the cutoff (≥8) for anxiety and 24 (23%) for depression. Women were more likely to report anxiety than men (odds ratio 4.04, 95% confidence interval 1.45-11.16), and patients reporting limitations in their activity status had more than five times greater odds of reporting depression (odds ratio 6.07, 95% confidence interval 1.53-24.10). A substantial proportion of esophageal cancer patients report anxiety and/or depression prior to surgery, particularly women and those with limited activity status, which highlights a need for qualified emotional support. © 2015 International Society for Diseases of the Esophagus.

    The incidence of postoperative complications and mortality are usually higher in patients with preoperative malnutrition. Malnutrition often preexists, particularly in patients undergoing surgery for esophageal cancer, which is substantially invasive. It is therefore important to understand the nutritional condition of patients and actively control perioperative nutrition.Our hospital has been providing nutritional status screening for patients before resection of esophageal cancer, and we report the current status and evaluation results in this article.This screening included 158 patients requiring radical resection of esophageal cancer.Age, comorbidity with diabetes, body mass index(BMI), serum albumin(Alb), Onodera's prognostic nutritional index(PNI), and Glasgow prognostic score(GPS)were used as nutritional indicators to stratify patients for analysis.Evaluation parameters included the incidence of postoperative complications(any complication, pulmonary complications, psychiatric disorder, and anastomotic leakage)and rates of long-term postoperative hospitalization.The analysis indicated that age, BMI, serum Alb, PNI, and GPS are useful for predicting the onset of postoperative complications and prolonged postoperative hospitalization.For such patients, more active nutritional control should be provided.

    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.

    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.

    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.

    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.

    This study quantified the risk of head and neck (HN) and esophageal cancers in 2770 Italian liver transplant (LT) recipients. A total of 186 post-transplant cancers were diagnosed-including 32 cases of HN cancers and nine cases of esophageal carcinoma. The 10-year cumulative risk for HN and esophageal carcinoma was 2.59%. Overall, HN cancers were nearly fivefold more frequent in LT recipients than expected (standardized incidence ratios - SIR=4.7, 95% CI: 3.2-6.6), while esophageal carcinoma was ninefold more frequent (SIR=9.1, 95% CI: 4.1-17.2). SIRs ranged from 11.8 in LT with alcoholic liver disease (ALD) to 1.8 for LT without ALD for HN cancers, and from 23.7 to 2.9, respectively, for esophageal carcinoma. Particularly elevated SIRs in LT with ALD were noted for carcinomas of tongue (23.0) or larynx (13.7). Our findings confirmed and quantified the large cancer excess risk in LT recipients with ALD. The risk magnitude and the prevalence of ALD herein documented stress the need of timely and specifically organized programs for the early diagnosis of cancer among LT recipients, particularly for high-risk recipients like those with ALD.

    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

    Background: Despite various advances in the treatment of Esophageal Cancer (EC), being one of the least responsive tumors to cancer therapy, the overall prognosis remains poor. Therefore, it is significant to understand various sociodemographic factors associated with EC to find out various schemes for primary prevention of the disease. Materials and Methods: This is a retrospective analysis of medical records of the EC patients registered in the regional cancer center of northwest India from January 2003 to December 2012. The site of the disease and the histology were also recorded in addition to the various sociodemographic parameters. Results: Out of 55,742 patients registered in our hospital; 3,667 were diagnosed to have EC. Male:female ratio was 1.15:1. The mean age was 54.6 ± 11.74 years; 66.15% of the patients were illiterate and 48.6% belonged to the low socioeconomic status. Smoking and alcohol consumption were identified as risk factors in 48 and 25.6% of the patients, respectively. Conclusions: The etiology in majority of the patients is linked to tobacco and alcohol, thus, modification of life style with limiting the use of addictions may be an effective strategy in the prevention of this dreaded and mostly incurable disease.

    Esophageal cancer at Moi Teaching and Referral Hospital (MTRH) is the leading cancer in men with a poor prognosis. A case control study (n = 159) aimed at the histology type, gender, and risk indicators was carried out at MTRH. Mantel Haenszel chi-square and logistic regression were employed for analysis. Squamous-cell carcinoma was the common histological type occurring in the middle third portion of the oesophagus. The occurrence of the cancer in males was 1.4 times that of females. The mean age was 56.1 yrs. Low socioeconomic, smoking, snuff use, alcohol, tooth loss, cooking with charcoal and firewood, hot beverage, and use of mursik were independently associated with esophageal cancer (P < 0.05). Using logistic regression adjusted for various factors, alcohol consumption was associated with the increased risk of esophageal cancer. AHR was 0.45 and 95% CI: 0.205–0.985, P = 0.046. A societal component of low socioeconomic conditions, a lifestyle component with specific practices such as the consumption of mursik, chang'aa, busaa, snuff, smoking, hot tea, poor oral hygiene, and an environmental component with potential exposure to high levels of nitrosamines, passive smoking, and cooking with coal, could be involved. The increase in experts at MTRH capable of diagnosing could be responsible for the increase in reporting this neoplasm. PMID:24490085

    Objective: To evaluate the lymph node metastasis (LNM) pattern and related prognostic factors for T1 esophageal cancer. Methods: Clinical data of 143 cases of pT1 esophageal cancer patients (120 male and 23 female patients with median age of 60 years) who underwent esophagectomy and lymph node resection during January 2011 and July 2016 at the Department of Esophageal Cancer of Tianjin Medical University Cancer Institute and Hospital were reviewed, including 50 cases of T1a patients and 93 cases of T1b patients. The LNM pattern was analyzed and the prognostic factors related to LNM were assessed by χ(2) test and Logistic regression analysis. Results: Of 143 patients, 25 patients had LNM. The LNM rates were 17.5% for pT1 tumors, 16.0%(8/50) for pT1a tumors, and 22.6%(21/93) for T1b tumors. Of 25 patients with LNM, one patient had cervical metastasis, 15 patients with thoracic metastasis, and 17 patients with abdominal metastasis. The relatively highest LNM sites were laryngeal recurrent nerve (8 cases), left gastric artery (8 cases), right and left cardiac (6 cases) and thoracic paraesophageal (5 cases). Logistic regression analysis showed that the depth of tumor infiltration (OR=4.641, 95%CI: 1.279 to 16.836, P=0.020), tumor size (OR=5.301, 95%CI: 1.779 to 15.792, P=0.003), tumor location (OR=3.238, 95% CI: 1.248 to 8.401, P=0.016), and tumor differentiation (OR=5.301, 95%CI: 1.719 to 16.347, P=0.004) were independent prognostic factors related to LNM for T1 esophageal cancer. Tumor size (OR=4.117, 95% CI: 1.228 to 13.806, P=0.022) was an independent risk factor related to thoracic LNM, and the vessel invasion (OR=6.058, 95% CI: 1.228 to 29.876, P=0.027) and tumor location (OR=8.113, 95% CI: 1.785-36.872, P=0.007) were independent prognostic factors related to abdominal LNM. Conclusions: T1 esophageal cancer has a relatively high LNM rate, and the depth of tumor infiltration, tumor size, tumor location and tumor differentiation are correlated with LNM. The LNM

    The current paper summarizes relevant recent research on the high risk of recurrence, multiple skin cancers and second primary cancers in the growing number of people with a history of skin cancer; the ultimate purpose is to better assess the burden of malignancy following skin cancer. A number of challenges exist in identifying and tracking both melanoma and non-melanoma skin cancer (NMSC) cases. Most jurisdictions do not routinely track NMSC cases and, even if they do, it is customary to only include the first diagnosis. There are variable rules for counting multiple melanoma cancers, and recurrences are not considered for either major type of skin cancer. Applying insights from recent studies of this issue to Canadian cancer statistics would increase reported diagnoses of NMSC by about 26% and melanoma by 10% in this country. This approach to a fuller assessment of the burden of skin cancers has been called a "diagnosis-based incidence approach" as compared with a "patient-based incidence approach". A further issue that is not usually taken into account when assessing the burden of skin cancers is the 20% to 30% elevated risk of noncutaneous second primary cancers following a primary skin tumour. In summary, individuals with skin cancer are subject to a high risk of recurrence, multiple skin cancers and second primary cancers. This burden should be a special concern in the large and growing pool of individuals with a history of skin cancer, as well as among prevention planners.

    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.

    Esophageal carcinomas have recently been shown to express Fas ligand (FasL) and down-regulate Fas to escape from host immune surveillance. However, the prognostic importance of Fas/FasL and their correlation with clinicopathological characteristics are yet to be delineated in this highly malignant carcinoma. Specimens from 106 esophageal squamous cell carcinoma patients were used for immuno-histochemical evaluation of Fas, FasL, and CD8 expressions. Fifty-two (49%) and 34 (32%) patients were positive for FasL and Fas, respectively. There were no associations between FasL expression and clinicopathological characteristics except lymph vessel invasion. Strong FasL expression correlated with significant (P < 0.001) decrease in tumor nest CD81 cells. However, neither FasL nor CD81 had any impact on patient survival. Strong Fas expression was correlated with depth of invasion (40.3% in pT1, T2 versus 20.5% in pT3, T4; P5 0.0308), histological differentiation (45.7% in well versus 25.4% in nonwell; P < 0.05), and lymph node metastasis (22.6% in positive versus 45.5% in negative; P < 0.01). Fas expression was one of the independent favorable prognosticators for patients’ survival (risk ratio, 3.26; P < 0.01) in esophageal SCC. Fas expression was an independent prognosticator for recurrencefree survival, whereas FasL expression did not influence the survival in esophageal squamous cell carcinoma. Down-regulation of tumor Fas may be the hallmark of immune privilege for the tumor, thus causing the patients’ poorer outcome. Tumor FasL may counterattack the host immune cells to such an extent that the prognosis is not affected. PMID:26609492

    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.

    Neoadjuvant therapy is commonly administered to patients with localized disease who have T3-4 esophageal disease as staged by endoscopic ultrasound (EUS). Previously, we noted that patients who present with dysphagia have a higher EUS T stage. We hypothesized that the presence of dysphagia is predictive of EUS T3-4 disease and that staging EUS could be forgone for esophageal cancer patients with dysphagia. We performed a prospective, intent-to-treat, single-cohort study in which patients with potentially resectable esophageal cancer completed a standardized four-tier dysphagia score survey. EUS was performed as part of our standard evaluation. To determine whether the presence of dysphagia predicted EUS T3-4 disease, the dysphagia score was compared with EUS T stage. The study enrolled 114 consecutive patients between August 2012 and February 2014: 77% (88 of 114) received neoadjuvant therapy, 18% (20 of 114) did not, and 5% (6 of 114) pursued treatment elsewhere. In total, 70% (80 of 114) underwent esophagectomy; of these, 54% (61 of 114) had dysphagia and 46% (53 of 114) did not. Dysphagia scores were 66% (40 of 61) grade 1, 25% (15 of 61) grade 2, and 10% (6 of 61) grade 3 to 4. Among patients with dysphagia, 89% (54 of 61) had T3-4 disease by EUS; among those without dysphagia, only 53% (28 of 53) had T3-4 disease by EUS (p < 0.001). The presence of dysphagia in patients with esophageal cancer was highly predictive of T3-4 disease by EUS. On the basis of this finding, approximately 50% of patients currently undergoing staging EUS at our institution could potentially forgo EUS before neoadjuvant therapy. Patients without dysphagia, however, should still undergo EUS. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

    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, these 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-posttreatment 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 to the other 54 patients who did not fail (median OS time: 16.5 months vs. 31.5 months, p=0.041). Acute and late toxicities were similar in both groups. Conclusions While 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 in distal esophageal

    2006-04-01

    Based on positive results from the Radiation Therapy Oncology Group (RTOG) 85-01 trial, the conventional nonsurgical treatment of esophageal carcinoma is combined-modality therapy. Dose intensification of the RTOG 85-01 regimen, examined in the Intergroup (INT)-0123/RTOG 94-05 trial, did not improve local control or survival. Areas of clinical investigation include the development of combined-modality therapy regimens with newer systemic agents, the use of 18F-fluorodeoxyglucose positron-emission tomography to assist in the development of innovative radiation treatment planning techniques, and the identification of prognostic molecular markers. The addition of surgery following primary combined-modality therapy apparently does not improve survival, but this finding is controversial.

    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.

    Background and Purpose Extended-volume external-beam radiation therapy (rt) following esophagectomy is controversial. The present prospective study evaluates the feasibility of extended-volume rt treatment in high-risk esophagectomy patients with a cervical anastomosis receiving postoperative combined chemoradiation therapy. Patients and Methods From 2001 to 2006, 15 patients with resected esophageal cancer were prospectively accrued to this pilot study to evaluate the adverse effects of extended-volume rt. Postoperative management was carried out at London Regional Cancer Program. Eligibility criteria were pathology-proven esophageal malignancy (T3–4, N0–1), disease amenable to surgical resection, and esophagectomy with or without resection margin involvement. Patients with distant metastases (M1) and patients treated with previous rt were excluded. All 15 study patients received 4 cycles of 5-fluorouracil–based chemotherapy. External-beam rt was conducted using conformal computed tomography planning, with multi-field arrangement tailored to the pathology findings, with coverage of a clinical target volume encompassing the primary tumour bed and the anastomotic site in the neck. The radiation therapy dose was 50.40 Gy at 1.8 Gy per fraction. The rt was delivered concurrently with the third cycle of chemotherapy. The study outcomes—disease-free survival (dfs) and overall survival (os)—were calculated by the Kaplan–Meier method.

    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.

  20. Tumor Initiation in Human Malignant Melanoma and Potential Cancer Therapies

    Cancer stem cells (CSCs), also known as tumor-initiating cells, have been identified in several human malignancies, including human malignant melanoma. The frequency of malignant melanoma-initiating cells (MMICs), which are identified by their expression of ATP-binding cassette (ABC) family member ABCB5, correlates with disease progression in human patients. Furthermore, targeted MMIC ablation through ABCB5 inhibits tumor initiation and growth in preclinical xenotransplantation models, pointing to potential therapeutic promise of the CSC concept. Recent advances also show that CSCs can exert pro-angiogenic roles in tumor growth and serve immunomodulatory functions related to the evasion of host anti-tumor immunity. Thus, MMICs might initiate and sustain tumorigenic growth not only as a result of CSC-intrinsic self-renewal, differentiation and proliferative capacity, but also based on pro-tumorigenic interactions with the host environment.

    Photodynamic therapy (PDT) is a form of non-ionizing radiation therapy that uses a drug, called a photosensitizer, combined with light to produce singlet oxygen (1O2) that can exert anti-cancer activity through apoptotic, necrotic, or autophagic tumor cell death. PDT is increasingly being used to treat thoracic malignancies. For early-stage non-small cell lung cancer (NSCLC), PDT is primarily employed as an endobronchial therapy to definitively treat endobronchial or roentgenographically occult tumors. Similarly, patients with multiple primary lung cancers may be definitively treated with PDT. For advanced or metastatic NSCLC and small cell lung cancer (SCLC), PDT is primarily employed to palliate symptoms from obstructing endobronchial lesions causing airway compromise or hemoptysis. PDT can be used in advanced NSCLC to attempt to increase operability or to reduce the extent of operation required, and selectively to treat pleural dissemination intraoperatively following macroscopically complete surgical resection. Intraoperative PDT can be safely combined with macroscopically complete surgical resection and other treatment modalities for malignant pleural mesothelioma (MPM) to improve local control and prolong survival. This report reviews the mechanism of and rationale for using PDT to treat thoracic malignancies, details prospective and major retrospectives studies of PDT to treat NSCLC, SCLC, and MPM, and describes improvements in and future roles and directions of PDT.

    Background: Pancreaticoduodenectomies are often undertaken with suspicion of malignancy. We undertook this study to determine if and how unnecessary pancreaticoduodenectomies can be avoided. Methods: Data from patients undergoing pancreaticoduodenectomy were prospectively collected. Operative indications, including presenting symptoms and results with imaging, with or without biopsy, were reviewed. Results: From 1996 through to 2007, 551 patients underwent pancreaticoduodenectomy at our institution. Chronic pancreatitis was the operative indication in 3% of patients; premalignant/malignant lesions were present in 86% of patients. Eleven per cent of patients underwent ‘unnecessary’ pancreaticoduodenectomies with presumptive diagnoses of cancer but were without premalignant/malignant disease on final report by Pathology [pancreatitis in 63%, serous cystadenomas (<4 cm) in 14%]. Of the unnecessary resections, 20% had histories and imaging sufficient to diagnose pancreatitis, 18% had inaccurate preoperative brushings/biopsies ‘documenting’ cancer, 11% had clear misinterpretations of their imaging studies and 7% had inadequate preoperative evaluations. However, 45% had signs/symptoms of cancer with a pancreatic head mass/biliary stricture. Conclusion: Only a small minority of patients undergoing pancreaticoduodenectomy for suspicion of periampullary cancer do so unnecessarily. Preoperative review of biopsies, better considerations of pancreatitis and careful evaluation of imaging, particularly for cystic masses, will decrease unnecessary pancreaticoduodenectomies.

    Esophageal cancer is one of the most common cancers in North East India. The molecular mechanisms of esophageal cancer susceptibility in North East India have not been fully understood. There is a need for identification of biomarkers to identify people at risk of esophageal cancer. p16 is an essential G1 cell cycle regulatory gene whose loss of function is associated with carcinogenesis. Therefore, we conducted this study to determine the prevalence of p16 gene methylation in patients with esophageal cancer to assess the feasibility of using gene methylation as a biomarker. 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 PCR was used to determine the p16 methylation status. Aberrant promoter methylation of the p16 gene was detected in 81 of 100 (81%) esophageal cancer cases. Hypermethylation of p16 gene was found to be influenced by lifestyle factors. Betel quid and tobacco chewing habit synergistically with p16 methylation elevated the risk for esophageal cancer development (adjusted odds ratio (OR) = 6.88, 95% confidence interval (CI) = 1.64-28.81, p = 0.003 for betel quid chewing and adjusted OR = 7.02, 95% CI = 1.87-26.38, p = 0.001 for tobacco chewing). Further, intake of green leafy vegetables and fruits lowered the risk of esophageal cancer (adjusted OR = 0.16, 95 % CI = 0.04-0.58, p = 0.05 for green leafy vegetables and adjusted OR = 0.15, 95% CI = 0.04-0.64, p = 0.01 for fruits). Thus, p16 hypermethylation may aid as a biomarker in identifying habitués at greater risk for esophageal cancer susceptibility in high incidence region of North East India.

    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

    Hyperglycemia is a common feature of diabetes mellitus, considered as a risk factor for cancer. However, its direct effects in cancer cell behavior are relatively unexplored. Herein we show that high glucose concentration induces aberrant glycosylation, increased cell proliferation, invasion and tumor progression of colon cancer. By modulating the activity of the rate-limiting enzyme, glutamine-fructose-6-phosphate amidotransferase (GFAT), we demonstrate that hexosamine biosynthetic pathway (HBP) is involved in those processes. Biopsies from patients with colon carcinoma show increased levels of GFAT and consequently aberrant glycans' expression suggesting an increase of HBP flow in human colon cancer. All together, our results open the possibility that HBP links hyperglycemia, aberrant glycosylation and tumor malignancy, and suggest this pathway as a potential therapeutic target for colorectal cancer.

    Purpose: To analyze retrospectively the long-term results of external beam radiotherapy (RT) with or without intraluminal brachytherapy (ILBT) for patients with Stage I esophageal cancer. Methods and Materials: A total of 34 patients with esophageal squamous cell carcinoma, clinically diagnosed as having Stage I disease, were treated with definitive RT, with or without ILBT. The median age was 69 years. Seven patients were treated with external beam RT alone (median, 64 Gy), and 27 were treated with external beam RT (median, 52 Gy) plus ILBT (8-12 Gy in two to three fractions). Results: The 5-year overall survival, local relapse-free survival, and cause-specific survival rate was 58.9%, 68.4%, and 80.0%, respectively, with a median follow-up of 61 months. Of 9 patients with local recurrence after initial therapy, 7 were successfully treated, and the 5-year cumulative rate of esophagectomy was 19.6%. The 2-year local relapse-free rate for patients with and without ILBT was 79.1% and 53.6%, respectively. Conclusion: Although local recurrence was frequent within 2 years, the disease-specific survival rate was high owing to effective salvage therapy. Definitive RT is a reasonable treatment option for highly comorbid and elderly patients with Stage I esophageal cancer. The role of ILBT needs to be clarified.

    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 in the 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 prospective cohort study was conducted to analyze whether self-reported fatigue predicts overall survival in patients with esophageal cancer. Patients enrolled in the Mayo Clinic Esophageal Adenocarcinoma and Barrett's Esophagus Registry between September 2001 and January 2009 who completed a baseline quality of life instrument were eligible for evaluation. The fatigue component was scored on a 0-10 scale, with 0 as extreme fatigue. Patients were categorized as having a decreased energy level if they reported a score of ≤ 5. Fatigue scores ≥ 6 reflect normal levels of energy. Data from a total of 659 enrolled patients were analyzed. A total of 392 (59 %) and 267 (41 %) patients reported decreased and normal energy, respectively. Univariate analysis indicates patients with normal energy had improved 5-year survival compared to patients with decreased energy (37 vs 28 %, hazard ratio (HR) 0.74, p = 0.006). Among the patients with locally advanced disease, the same relationship was seen (28 vs 17 %, HR = 0.67, p = 0.003); this remained significant on multivariate analysis (HR = 0.71, p = 0.015). A decreased energy level is associated with poor survival in patients with esophageal cancer. Thus, patients with high levels of fatigue should be referred for psychological support and be considered for therapy aimed at amelioration of fatigue symptoms.

    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.

    Amonafide, a synthetic benzisoquinolinedione, was evaluated for treatment of squamous esophageal cancer. Eleven men and 5 women were eligible with a median performance status of 1 and median age of 63 years. Six had no prior treatment. All patients had measurable disease. Therapy consisted of amonafide 300 mg/m2d days 1-5 every 21 days. Thirty-five courses of therapy were delivered. The median number of courses received was two. Sixteen patients are evaluable for toxicity. Thirteen are evaluable for response. Toxicity was severe. Seven patients were hospitalized for toxicity. Six patients had grade IV granulocytopenia; two, grade IV thrombocytopenia. Angioedema developed in one patient; severe exfoliative dermatitis in another. A single partial response, with the decrease in size a supraclavicular node, was noted in a previously untreated patient. Amonafide, in this dose and schedule, is associated with occasionally severe toxicity precluding its likely use in squamous cell esophageal carcinoma.

    The widespread popularity of new surgical technologies such as laparoscopy, thoracoscopy and robotics has led many surgeons to treat esophageal diseases with these methods. The expected benefits of minimally invasive surgery (MIS) mainly include reductions of postoperative complications, length of hospital stay, and pain and better cosmetic results. All of these benefits could potentially be of great interest when dealing with the esophagus due to the potentially severe complications that can occur after conventional surgery. Moreover, robotic platforms are expected to reduce many of the difficulties encountered during advanced laparoscopic and thoracoscopic procedures such as anastomotic reconstructions, accurate lymphadenectomies, and vascular sutures. Almost all esophageal diseases are approachable in a minimally invasive way, including diverticula, gastro-esophageal reflux disease, achalasia, perforations and cancer. Nevertheless, while the limits of MIS for benign esophageal diseases are mainly technical issues and costs, oncologic outcomes remain the cornerstone of any procedure to cure malignancies, for which the long-term results are critical. Furthermore, many of the minimally invasive esophageal operations should be compared to pharmacologic interventions and advanced pure endoscopic procedures; such a comparison requires a difficult literature analysis and leads to some confounding results of clinical trials. This review aims to examine the evidence for the use of MIS in both malignancies and more common benign disease of the esophagus, with a particular emphasis on future developments and ongoing areas of research.

    Although substantial studies on peroxisome proliferator-activated receptor g (PPARg) have focused on the mechanisms by which PPARg regulates glucose and lipid metabolism, recent reports have suggested that PPARg shows tumorigenic or antitumorigenic effects. The roles and mechanisms of PPARg activation in esophageal cancer remain unclarified. EC109 and TE10 esophageal cancer cells were treated with 0, 10, 20 and 40 mM of PPARg agonist rosiglitazone (RGZ) for 24, 48, and 72 h, and the cell viability and apoptosis were detected using methyl thiazolyl tetrazolium (MTT) assay and Flow cytometric (FCM) analysis, respectively. Moreover, the effects of inhibition of PPARg by antagonist or specific RNA interference on cell viability, apoptosis, the Toll-like receptor 4 (TLR4) and mitogen-activated protein kinase (MAPK) pathways were evaluated. Additionally, the effect of TLR4 signaling on the MAPK pathway, cell viability and apoptosis was assessed. The results showed that RGZ suppressed proliferation and induced apoptosis of esophageal cancer cells, which could be partly restored by inactivation of PPARg. RGZ suppressed the MAPK and TLR4 pathways, and the inhibitory effect could be counteracted by PPARg antagonist or specific RNA interference. We also suggested that MAPK activation was regulated by the TLR4 pathway and that blocking the TLR4 and MAPK pathways significantly suppressed proliferation and induced apoptosis of esophageal cancer cells. In conclusion, our data suggested that activation of PPARg suppressed proliferation and induced apoptosis of esophageal cancer cells by inhibiting TLR4-dependent MAPK pathway.

    Purpose: To describe patient characteristics and the process of radiotherapy (RT) for patients with esophageal cancer treated between 1999 and 2001 in Japan. Methods and Materials: The Japanese Patterns of Care Study (PCS) Working Group conducted a third nationwide survey of 76 institutions. Detailed information was accumulated on 621 patients with thoracic esophageal cancer who received RT. Results: The median age of patients was 68 years. Eighty-eight percent were male, and 12% were female. Ninety-nine percent had squamous cell carcinoma histology. Fifty-five percent had the main lesion in the middle thoracic esophagus. Fourteen percent had clinical Stage 0-I disease, 32% had Stage IIA-IIB, 43% had Stage III, and 10% had Stage IV disease. Chemotherapy was given to 63% of patients; 39% received definitive chemoradiotherapy (CRT) without surgery and 24% pre- or postoperative CRT. Sixty-two percent of the patients aged {>=}75 years were treated with RT only. Median total dose of external RT was 60 Gy for definitive CRT patients, 60 Gy for RT alone, and 40 Gy for preoperative CRT. Conclusions: This PCS describes general aspects of RT for esophageal cancer in Japan. Squamous cell carcinoma accounted for the majority of patients. The standard total external RT dose for esophageal cancer was higher in Japan than in the United States. Chemoradiotherapy had become common for esophageal cancer treatment, but patients aged {>=}75 years were more likely to be treated by RT only.
