Abstract
Introduction The overall 5-year survival rate for esophageal cancer patients in low- and middle-income countries was reported to be low, despite the availability of advanced treatments. Thus, this study aimed to assess determinants of survival outcomes among esophageal cancer patients in Kenya. Methods A retrospective cohort study was employed among 299 adult esophageal cancer patients. The data were collected using a data abstraction tool consisting of patients' clinical characteristics and survival outcome measuring parameters. Statistical Package for the Social Sciences (SPSS) statistical software (version 20.0, IBM. USA) was used to analyze the data. The Kaplan-Meier and Cox regression analyses were used to determine the survival outcome and determinants of mortality, respectively. Results The mortality rate was 43.1%, and 11.1% of patients demonstrated distant metastases in the follow-up period. Despite treatment, 20.1% had progressed disease, and 13.0% did not respond to treatment. Radiotherapy (AHR: 3.3, 95% CI: 1.4-7.8, p = 0.007), chemotherapy (AHR: 3.9, 95% CI: 1.2-6.1, p = 0.020), and chemoradiation (AHR: 5.6, 95%CI: 1.6-10.2, p = 0.006) were the significant determinants of survival in advanced stage (III and and IV) patients. Conclusions There was a high mortality rate, disease progression, and nonresponse of esophageal cancer patients. Hence, it is essential to improve the survival of patients through early detection and timely initiation of the available treatment options.

Abstract
OBJECTIVES To evaluate the occurrence, abundance, distribution, nature and clinical significance of multinucleated giant cell (MGC) in esophageal cancer. MATERIALS AND METHODS MGCs were examined with conventional pathology, immunohistochemistry and immunofluorescence in 107 esophageal cancer tissues. The findings were correlated to pathological diagnosis and clinical behavior of the cancers. RESULTS MGCs were identified in 31.7% (34/107) of the cases. MGCs were positive for CD11c, CD11b, CD32, CD16, HLA-DR and MMP9, and negative for CD163, CD206 and CD64 giving a molecular profile of proinflammatory M1 but not immunosuppressive M2. MGCs were significantly related to decreased lymph node metastasis (p = 0.011), low pTNM stage (p = 0.044), favorable survival (p = 0.04), squamous cell cancer type rather than other histopathological subtypes (p = 0.020) and associated to better differentiation (p = 0.063). CONCLUSIONS MGCs belong to M1 macrophage and perform phagocytosis and scavenging of cancer cells that would benefit patients' survival and could serve as a prognostic marker.

Abstract
Gastroesophageal reflux disease (GERD), a clinical condition characterized by reflux of gastroduodenal contents in the oesophagus, has proved to demonstrate a strong link between oxidative stress and the development of GERD. Proton pump inhibitors (PPIs) have been universally accepted as first-line therapy for management of GERD. The potential benefits of electrolysed reduced water (ERW), rich in molecular hydrogen, in improving symptoms and systemic oxidative stress associated with GERD was assessed. The study was performed on 84 GERD patients undergoing control treatment (PPI + tap water) or experimental treatment (PPI + ERW) for 3 months. These patients were subjected to the GERD-Health Related Quality of Life Questionnaire as well as derivatives reactive oxigen metabolites (d-ROMs) test, biological antioxidant potential (BAP) test, superoxide anion, nitric oxide and malondialdehyde assays, which were all performed as a proxy for the oxidative/nitrosative stress and the antioxidant potential status. Spearman's correlation coefficient was used to evaluate the correlation between scores and laboratory parameters. Overall results demonstrated that an optimal oxidative balance can be restored and GERD symptoms can be reduced rapidly via the integration of ERW in GERD patients. The relative variation of heartburn and regurgitation score was significantly correlated with laboratory parameters. Thus, in the selected patients, combination treatment with PPI and ERW improves the cellular redox state leading to the improvement of the quality of life as demonstrated by the correlation analysis between laboratory parameters and GERD symptoms.

Abstract
BACKGROUND Most patients with oesophageal and gastro-oesophageal carcinoma are diagnosed at an advanced stage and require palliative intervention. Although there are many kinds of interventions, the optimal one for the palliation of dysphagia remains unclear. This review updates the previous version published in 2009. OBJECTIVES The aim of this review was to systematically analyse and summarise the efficacy of different interventions used in the palliation of dysphagia in primary oesophageal and gastro-oesophageal carcinoma. SEARCH METHODS To find new studies for this updated review, in January 2014 we searched, according to the Cochrane Upper Gastrointestinal and Pancreatic Diseases model, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE and CINAHL; and major conference proceedings (up to January 2014). SELECTION CRITERIA Only randomised controlled trials (RCTs) were included in which patients with inoperable or unresectable primary oesophageal cancer underwent palliative treatment. Different interventions like rigid plastic intubation, self-expanding metallic stent (SEMS) insertion, brachytherapy, external beam radiotherapy, chemotherapy, oesophageal bypass surgery, chemical and thermal ablation therapy, either head-to-head or in combination, were included. The primary outcome was dysphagia improvement. Secondary outcomes included recurrent dysphagia, technical success, procedure related mortality, 30-day mortality, adverse effects and quality of life. DATA COLLECTION AND ANALYSIS Data collection and analysis were performed in accordance with the methods of the Cochrane Upper Gastrointestinal and Pancreatic Diseases Review Group. MAIN RESULTS We included 3684 patients from 53 studies. SEMS insertion was safer and more effective than plastic tube insertion. Thermal and chemical ablative therapy provided comparable dysphagia palliation but had an increased requirement for re-interventions and for adverse effects. Anti-reflux stents provided comparable dysphagia palliation to conventional metal stents. Some anti-reflux stents might have reduced gastro-oesophageal reflux and complications. Newly-designed double-layered nitinol (Niti-S) stents were preferable due to longer survival time and fewer complications compared to simple Niti-S stents. Brachytherapy might be a suitable alternative to SEMS in providing a survival advantage and possibly a better quality of life, and might provide better results when combined with argon plasma coagulation or external beam radiation therapy. AUTHORS' CONCLUSIONS Self-expanding metal stent insertion is safe, effective and quicker in palliating dysphagia compared to other modalities. However, high-dose intraluminal brachytherapy is a suitable alternative and might provide additional survival benefit with a better quality of life. Some anti-reflux stents and newly-designed stents lead to longer survival and fewer complications compared to conventional stents. Combinations of brachytherapy with self-expanding metal stent insertion or radiotherapy are preferable due to the reduced requirement for re-interventions. Rigid plastic tube insertion, dilatation alone or in combination with other modalities, and chemotherapy alone are not recommended for palliation of dysphagia due to a high incidence of delayed complications and recurrent dysphagia.

Abstract
Background Ubiquitination is a reversible process of posttranslational protein modification through the action of the family of deubiquitylating enzymes which contain ubiquitin-specific protease 9x (USP9X). Recent evidence indicates that USP9X is involved in the progression of various human cancers. The aim was to detect the expression of USP9X in the progression from normal epithelium to invasive esophageal squamous cell cancer (ESCC) and evaluate the relevance of USP9X expression to the tumor progression and prognosis. Methods In this study, USP9X immunohistochemical analysis was performed on tissues constructed from ESCC combined with either normal epithelium or adjacent precursor tissues of 102 patients. All analyses were performed by SPSS 13.0 software. Results We observed that the level of high USP9X expression increased gradually in the transformation from normal epithelium (4.0%), to low grade intraepithelial neoplasia (10.5%), then to high grade intraepithelial neoplasia (28.6%), and finally to invasive ESCC (40.2%). The expression of USP9X was found to be significantly different between the normal mucosa and ESCC (P < 0.001), and between low grade intraepithelial neoplasia and high grade intraepithelial neoplasia (p = 0.012). However, no difference was observed between the high expression of USP9X in normal mucosa and low grade intraepithelial neoplasia (P = 0.369), nor between high grade intraepithelial neoplasia and ESCC (p = 0.115). Interestingly, the most intensive staining for USP9X was usually observed in the basal and lower spinous layers of the esophageal epithelium with precursor lesions which often resulted in the earliest malignant lesion. USP9X expression status was positively associated with both depth of invasion (p = 0.046) and lymph node metastasis (p = 0.032). Increased USP9X expression was significantly correlated to poorer survival rate in ESCC patients (p = 0.001). When adjusted by multivariate analysis, USP9X expression (HR 2.066, P = 0.005), together with TNM stage (HR 1.702, P = 0.042) was an independent predictor for overall survival. Conclusions Up-regulation of USP9X plays an important role in formation and progression of precancerous lesions in ESCC and USP9X expression levels were significantly correlated with the survival of ESCC patients. Thus, USP9X could be considered as a potential biomarker and prognostic predictor for ESCC.

Abstract
BACKGROUND In spite of multimodular treatment, the therapeutic options for esophageal carcinoma are limited, and metastases remain the leading cause of tumor-related mortality. Expression of the chemokine receptor CXCR4 significantly correlates with poor survival rates in patients with esophageal carcinoma and is associated with lymph node and bone marrow metastases. The aim of this study was to evaluate the effect of the CXCR4 antagonist CTCE-9908 on metastatic homing and primary tumor growth in vitro and in vivo in an orthotopic xenograft model of esophageal cancer. MATERIALS AND METHODS OE19 cells were examined for stromal cell-derived factor 1 alpha-mediated migration under CTCE-9908 treatment. The CTCE-9908 treatment was further evaluated in an in vitro proliferation assay and orthotopic esophageal model, accompanied by magnetic resonance imaging. Tumor and metastases were immunohistochemically examined for CXCR4 expression. RESULTS CTCE-9908 has an inhibitory effect on stromal cell-derived factor 1 alpha-mediated migration and proliferation of OE19 cells. Treatment with CTCE-9908 in the orthotopic esophageal model leads to a reduction of metastatic spread and primary tumor growth. This was confirmed by magnetic resonsance imaging. Treatment with CTCE-9908 results in altered CXCR4 expression pattern exhibiting a high degree of variability. CONCLUSION CTCE-9908 effectively inhibits OE19 cell migration and proliferation in vitro, reduces metastases to lung, liver, and lymph nodes in vivo, and moreover leads to tumor growth reduction in an orthotopic model of esophageal carcinoma.

Abstract
BACKGROUND Fully covered esophageal self-expandable metallic stents (SEMS) often are used for palliation of malignant dysphagia. However, experience and data on these stents are still limited. The purpose of this multicenter study was to evaluate the efficacy and safety of fully covered nitinol SEMS in patients with malignant dysphagia. METHODS 37 patients underwent placement of a SEMS during a 3 year period. Five patients underwent SEMS placement as a bridge to surgery: one for tracheoesophageal fistula in the setting of squamous cell carcinoma of the esophagus, one for perforation in setting of esophageal adenocarcinoma, 27 for unresectable esophageal cancer (16 adenocarcinoma, 11 squamous cell carcinoma), two for lung cancer, and one for breast-cancer-related esophageal strictures. RESULTS SEMS placement was successful in all 37 patients. Immediate complications after stent deployment included chest pain (n = 6), severe heartburn (n = 1), and upper gastrointestinal bleeding requiring SEMS revision (n = 1). Dysphagia scores improved significantly from 3.2 ± 0.4 before stent placement to 1.4 ± 1.0 at 1 month (P < 0.0001), 1.1 ± 1.2 (P < 0.0001) at 3 months, and 1.3 ± 1.4 (P = 0.0018) at 6 months. The stent was removed in 11 patients (30%) for the following indications: resolution of stricture (n = 3), stent malfunction (n = 5), and stent migration (n = 3). After stent removal, three patients were restented, three underwent dilation, and two underwent PEG placement. Mean survival for the 37 patients after stent placement was 146.3 ± 143.6 (range, 13-680) days. CONCLUSIONS Our study suggests that fully covered SEMS placement improve dysphagia scores in patients with malignant strictures, particularly in the unresectable population. Further technical improvements in design to minimize long-term malfunction and migration are required.

Abstract
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 endoscopy technique in conjunction with biomolecular modeling has promising potential for the real-time, in vivo diagnosis and detection of esophageal cancer during clinical endoscopic examination.

Abstract
Raman spectroscopy is an optical vibrational technology capable of probing biomolecular changes of tissue associated with cancer transformation. This study aimed to characterize in vivo Raman spectroscopic properties of tissues belonging to different anatomical regions in the upper gastrointestinal (GI) tract and explore the implications for early detection of neoplastic lesions during clinical gastroscopy. A novel fiber-optic Raman endoscopy technique was utilized for real-time in vivo tissue Raman measurements of normal esophageal (distal, middle, and proximal), gastric (antrum, body, and cardia) as well as cancerous esophagous and gastric tissues from 107 patients who underwent endoscopic examinations. The non-negativity-constrained least squares minimization coupled with a reference database of Raman active biochemicals (i.e., actin, histones, collagen, DNA, and triolein) was employed for semiquantitative biomolecular modeling of tissue constituents in the upper GI. A total of 1189 in vivo Raman spectra were acquired from different locations in the upper GI. The Raman spectra among the distal, middle, and proximal sites of the esophagus showed no significant interanatomical variability. The interanatomical variability of Raman spectra among normal gastric tissue (antrum, body, and cardia) was subtle compared to cancerous tissue transformation, whereas biomolecular modeling revealed significant differences between the two organs, particularly in the gastroesophageal junction associated with proteins, DNA, and lipids. Cancerous tissues can be identified across interanatomical regions with accuracies of 89.3% [sensitivity of 92.6% (162∕175); specificity of 88.6% (665∕751)], and of 94.7% [sensitivity of 90.9% (30∕33); specificity of 93.9% (216∕230)] in the gastric and esophagus, respectively, using partial least squares-discriminant analysis together with the leave-one tissue site-out, cross validation. This work demonstrates that Raman endoscopy technique has promising clinical potential for real-time, in vivo diagnosis and detection of malignancies in the upper GI at the molecular level.

Abstract
BACKGROUND The majority of oesophageal and gastro-oesophageal cancers are diagnosed at an advanced stage and palliative treatment is the realistic management option for most patients. The optimal intervention for the palliation of dysphagia in these patients has not been established. OBJECTIVES To systematically analyse and summarise the efficacy of different interventions used in the palliation of dysphagia in primary oesophageal carcinoma. SEARCH STRATEGY We undertook a search according to the Cochrane Upper Gastrointestinal and Pancreatic Diseases model using the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE and CINAHL and major conference proceedings up to August 2005. The literature search was re-run in August 2006 and March 2007. SELECTION CRITERIA Randomised controlled trials (RCTs) in patients with inoperable or unresectable primary oesophageal cancer who underwent palliative treatment. We included rigid plastic intubation, self-expanding metallic stent (SEMS) insertion, brachytherapy, external beam radiotherapy, chemotherapy, oesophageal bypass surgery, chemical and thermal ablation therapy, either head-to-head or in combination. The primary outcome was dysphagia improvement. Secondary outcomes included recurrent dysphagia, technical success, procedure related mortality, 30-day mortality, adverse effects and quality of life. DATA COLLECTION AND ANALYSIS One author assessed the eligibility criteria of each study and extracted data regarding outcomes and factors affecting risk of bias. MAIN RESULTS We included 2542 patients from 40 studies. SEMS insertion is safer and more effective than plastic tube insertion. Thermal and chemical ablative therapy provide comparable dysphagia palliation but have an increased requirement for re-interventions and adverse effects. Anti-reflux stents provide comparable dysphagia palliation to conventional metal stents. Some anti-reflux stents might reduce gastro-oesophageal reflux compared to conventional metal stents. Brachytherapy might be a suitable alternative to SEMS in providing a survival advantage and possibly a better quality of life. AUTHORS' CONCLUSIONS Self-expanding metal stent insertion is safe, effective and quicker in palliating dysphagia compared to other modalities. However, high-dose intraluminal brachytherapy is a suitable alternative and might provide additional survival benefit with a better quality of life. Self-expanding metal stent insertion and brachytherapy provide comparable palliation to endoscopic ablative therapy but are preferable due to the reduced requirement for re-interventions. Rigid plastic tube insertion, dilatation alone or in combination with other modalities, chemotherapy alone, combination chemoradiotherapy and bypass surgery are not recommended for palliation of dysphagia due to a high incidence of delayed complications and recurrent dysphagia.

Abstract
AIMS Survivin (SVV) mRNA expression levels in peripheral blood of patients with gastrointestinal malignancies change significantly during the course of treatment. We wanted to scrutinize these findings in patients with esophageal carcinoma and furthermore evaluate whether the detection of mRNA and the change in detecting ability have an association with overall survival. MATERIALS & METHODS Whole blood was drawn 1 day pre- and 10 days post-operatively from 62 patients with esophageal carcinoma. Tumor cells were enriched from whole blood by density-gradient centrifugation prior to extraction of total cellular RNA and subsequent direct quantitative reverse transcriptase-PCR assays. RESULTS SVV was detectable in 48 out of 62 patients (77%). Stepwise multivariate Cox linear regression models demonstrated a significant and independent association of measured SVV with overall survival (6.6 exp[b]; 95% CI: 1.97-22.12; p = 0.002). Increased SVV levels after the operation were linked to shorter overall survival (p = 0.04). CONCLUSION Preoperative SVV expression levels appear to be associated with overall survival in patients with esophageal cancers. Increasing levels could potentially indicate a higher risk for shorter overall survival and therefore demand adapted treatment modalities.

Abstract
The treatment of esophageal cancer with curative intent remains highly controversial, with advocates of surgery alone, chemoradiotherapy alone, surgery with adjuvant therapy (including neoadjuvant and postoperative), and trimodality therapy each contributing prospective randomized controlled trials (PRCTs) to the body of scientific publications between 2000 and 2008. Any improvements in survival have been small in absolute percentage terms, and as such PRCTs published over the last decade have met the same primary obstacle encountered by the studies from the two prior decades, namely lack of power to detect small differences in outcome. Variations in staging methods, surgical technique, radiotherapy technique, and chemotherapy regime have in turn been the subject of PRCTs over the last nine years. In many cases primary end points have not been survival but rather rates of complication or response. As well as giving an overview of PRCTs, this article collates the level Ia evidence published to date.

Methylated DAPK and APC promoter DNA detection in peripheral blood is significantly associated with apparent residual tumor and outcome. J Cancer Res Clin Oncol 2009; 135:1231-7.

Abstract
BACKGROUND Death-associated protein kinase (DAPK) and adenomatous polyposis coli gene (APC) have been recently shown to be associated with outcome in patients with esophageal carcinoma, especially adenocarcinoma. We wanted to validate the correlation of these two markers with outcome by detecting methylated DNA sequences in peripheral blood. METHODS Circulating cell-free DNA extracted from blood plasma of 59 patients with esophageal cancer was analyzed before and after surgical resection by quantitative real-time methylation-specific RT-PCR (TaqMan) assays. RESULTS Thirty-six of 59 patients (61.0%) with esophageal cancer had detectable levels of methylated DAPK or APC promoter DNA and preoperative detection was significantly associated with an unfavorable prognosis as revealed by multivariate Cox proportional hazards regression analysis [Exp(b) = 4.578; P = 0.01]. The combination of both markers significantly increased sensitivity and specificity for discriminating between short (<2.5 years) and long survivors (P = 0.04, ROC curve analysis). Postoperative APC detection was significantly different if residual tumor was apparent (P = 0.03). CONCLUSIONS Preoperative measurement of methylated DAPK and APC promoter DNA in peripheral blood may contribute to better estimate postoperative survival chances of patients with esophageal carcinoma, especially adenocarcinoma. The postoperative detection of methylated APC in peripheral blood might provide crucial information on apparent residual tumor and might be used as a "molecular" R0-Marker in addition to the pathologic examination.

Abstract
BACKGROUND Esophageal cancer is one of the most frequent cancers worldwide and is associated with poor outcome. Besides clinicopathological data, few prognostic molecular markers exist. Esophageal-cancer-related gene1 (ECRG1) short tandem repeats are associated with higher risk for developing esophageal squamous cell carcinoma. The aim of the present study was to evaluate the impact of DNA polymorphisms in the coding region of ECRG1 in esophageal carcinoma. METHODS Genomic DNA of 107 patients with esophageal cancer that underwent complete surgical resection between 1997 and 2005 was extracted. DNA was analyzed for ECRG1 polymorphisms Arg290Arg, Arg290Gln, and Gln290Gln by PCR and gel electrophoresis. Polymorphisms were correlated with survival data by the Kaplan-Meier method, multivariate Cox regression analysis, and odds ratio were determined. For all variables, cross tables were generated, followed by calculation of the p value by using the chi-square test/Fisher-exact test. RESULTS Follow-up data of 102 patients with esophageal cancer were available after complete surgical resection for a median follow-up time of 24.3 months. Polymorphism Arg290Arg was found in 47 patients (46.1%), Arg290Gln in 48 patients (47.0%), and Gln290Gln in seven cases (6.9%). Arg290Arg polymorphism was significantly associated with reduced overall survival (p = 0.01) and tumor-free survival (p = 0.01) by the log-rank test. Multivariate regression analysis by Cox revealed polymorphism Arg290Arg to be a significant prognostic factor for survival (p = 0.012). CONCLUSIONS Polymorphism Arg290Arg in ECRG1 is associated with poor clinical outcome after complete surgical resection in patients with esophageal cancer.

Abstract
BACKGROUND Short tandem repeat (STR) polymorphisms in exon 4 of the esophageal cancer-related gene 2 (ECRG2) are a risk marker for esophageal carcinoma. The aim of the present study was to correlate these STRs with clinical outcome. METHODS Genomic DNA of 86 patients who underwent complete surgical resection was analyzed for STRs TCA3/TCA3, TCA3/TCA4, and TCA4/TCA4 in exon 4 of ECRG2 by polymerase chain reaction and DNA sequencing. RESULTS ECRG2 STR TCA3/TCA3 and TCA3/TCA4 were found in 40 (47%) patients, respectively, and TCA4/TCA4 in 6 (7%) cases. TCA3/TCA3 genotype was significantly associated with reduced survival (P < .05, log-rank test). TCA3/TCA3 STR was the strongest prognostic factor determined by multivariate Cox regression analysis. CONCLUSIONS Genetically fixed STR polymorphism TCA3/TCA3 in exon 4 of ECRG2 is associated with poor clinical outcome in surgically treated esophageal cancer patients and might be a potential prognostic marker. The usefulness of these genetic markers to predict responsiveness toward neoadjuvant treatment of esophageal cancer patients would be of high clinical interest and should be examined in future studies.

Abstract
BACKGROUND The oral health status of rural residents in the People's Republic of China has not been extensively studied and the relationship between poor oral health and esophageal cancer (EC) is unclear. We aim to report the oral health status of adults participating in an EC screening study conducted in a rural high-risk EC area of China and to explore the relationship between oral health and esophageal dysplasia. METHODS National Health and Nutrition Examination Survey (NHANES) oral health examination procedures and the Modified Gingival Index (MGI) were used in a clinical study designed to examine risk factors for esophageal cancer and to test a new esophageal cytology sampling device. This study was conducted in three rural villages in China with high rates of EC in 2002 and was a collaborative effort involving investigators from the National Institutes of Health and the Cancer Institute of the Chinese Academy of Medical Sciences. RESULTS Nearly 17% of the study participants aged 40-67 years old were edentulous. Overall, the mean number of adjusted missing teeth (including third molars and retained dental roots) was 13.8 and 35% had 7 contacts or less. Women were more likely to experience greater tooth loss than men. The average age at the time of first tooth loss for those with no posterior functional contacts was approximately 41 years for men and 36 years for women. The mean DMFT (decayed, missing, and filled teeth) score for the study population was 8.5. Older persons, females, and individuals having lower educational attainment had higher DMFT scores. The prevalence of periodontal disease (defined as at least one site with 3 mm of attachment loss and 4 mm of pocket depth) was 44.7%, and 36.7% of the study participants had at least one site with 6 mm or more of attachment loss. Results from a parsimonious multivariate model indicate that participants with poor oral health wemore likely to have esophageal dysplasia (OR = 1.59; 95% CI 1.06, 2.39). CONCLUSION This report describes the first use of NHANES oral health protocols employed in a clinical study conducted outside of the United States. The extent and severity of poor oral health in this Chinese study group may be an important health problem and contributing factor to the prevalence of EC.

Abstract
Cancer of the esophagus continues to be a threat to public health. The common practice is esophagectomy for surgically resectable tumors and radiochemotherapy for locally advanced, unresectable tumors. However, local regional tumor control and overall survival of esophageal cancer patients after the standard therapies remain poor, approximately 30% of patients treated with surgery only will develop local recurrence, and 50% to 60% patients treated with radiochemotherapy only fail local regionally due to persistent disease or local recurrence. Esophagectomy after radiochemotherapy or preoperative radiochemotherapy has increased the complete surgical resection rate and local regional control without a significant survival benefit. Induction chemotherapy followed by preoperative radiochemotherapy has produced encouraging results. In addition to patient-, tumor-, and treatment-related factors, involvement of celiac axis nodes, number of positive lymph nodes after preoperative radiochemotherapy, incomplete pathologic response, high metabolic activity on positron emission tomography scan after radiochemotherapy, and incomplete surgical resection are factors associated with a poor outcome. Radiochemotherapy followed by surgery is associated with significant adverse effects, including treatment-related pneumonitis, postoperative pulmonary complications, esophagitis and pericarditis. The incidence and severity of the adverse effects are associated with chemotherapy and radiotherapy dosimetric factors. Innovative treatment strategies including physically and biologically molecular targeted therapy is needed to improve the treatment outcome of patients with esophageal cancer.

Abstract
BACKGROUND Resectable oesophageal cancer is often treated with surgery alone or with preoperative (neoadjuvant) chemoradiotherapy or chemotherapy. We aimed to clarify the benefits of neoadjuvant chemoradiotherapy or chemotherapy versus surgery alone by a meta-analysis of randomised trial data. METHODS Eligible trials were identified first from earlier published meta-analyses and systematic reviews. We also used MEDLINE, Cancerlit, and EMBASE databases to identify additional studies and published abstracts from major scientific meetings since 1980. Only randomised studies with an analysis by an intention-to-treat principle were included, and searches were restricted to those databases citing articles in English. We used published hazard ratios if available or estimates from other survival data or survival curves. Treatment effects by type of tumour and treatment sequencing were also investigated. FINDINGS Ten randomised comparisons of neoadjuvant chemoradiotherapy versus surgery alone (n=1209) and eight of neoadjuvant chemotherapy versus surgery alone (n=1724) in patients with local operable oesophageal carcinoma were identified. The hazard ratio for all-cause mortality with neoadjuvant chemoradiotherapy versus surgery alone was 0.81 (95% CI 0.70-0.93; p=0.002), corresponding to a 13% absolute difference in survival at 2 years, with similar results for different histological tumour types: 0.84 (0.71-0.99; p=0.04) for squamous-cell carcinoma (SCC), and 0.75 (0.59-0.95; p=0.02) for adenocarcinoma. The hazard ratio for neoadjuvant chemotherapy was 0.90 (0.81-1.00; p=0.05), which indicates a 2-year absolute survival benefit of 7%. There was no significant effect on all-cause mortality of chemotherapy for patients with SCC (hazard ratio 0.88 [0.75-1.03]; p=0.12), although there was a significant benefit for those with adenocarcinoma (0.78 [0.64-0.95]; p=0.014). INTERPRETATION A significant survival benefit was evident for preoperative chemoradiotherapy and, to a lesser extent, for chemotherapy in patients with adenocarcinoma of the oesophagus. The findings provide an evidence-based framework for the use of neoadjuvant treatment in management decisions.

Abstract
OBJECTIVE The incidence of oesophageal cancer is increasing but the prognosis is still very poor. Around 50% of patients have advanced disease when diagnosed. Stenting using expandable metal stents is primarily aimed at palliation. The purpose of this study was to evaluate factors influencing morbidity, procedure-related mortality and symptom relief for dysphagia in patients with unresectable oesophageal cancer treated with self-expanding metal stents. MATERIAL AND METHODS We conducted a retrospective observational clinical study of consecutive patients treated with self-expanding metal stents in the Department of Surgery, Danderyd Hospital, Sweden, between January 1993 and May 2005. RESULTS One hundred and seventy-four stents were placed in 149 patients. The procedure-related mortality was 3% and the complication rate 26%. Pre- and post-treatment dysphagia could be evaluated in 139 stent placements, and showed significant improvement of dysphagia symptoms in 70% of subjects (p<0.0001). Tumour length, tumour location, histology, age, gender or prior dilatation did not affect the outcome regarding procedure-related morbidity or symptom relief. CONCLUSIONS Palliation of malignant dysphagia with self-expanding metal stents is safe and confers almost immediate improvement of dysphagia in the majority of patients. Tumour-related and demographic factors do not seem to influence the outcome.

Abstract
BACKGROUND Fascin, an actin-binding protein, is usually expressed at a low level in normal epithelium, but is markedly up regulated in several types of carcinomas. Reports on fascin expression in oesophageal squamous cell carcinoma (ESCC) and precancerous lesions remain rare. AIM To show the roles of fascin in the progression from normal epithelium to invasive ESCC. METHODS Fascin expression in 102 sections embedded in paraffin wax, including samples of normal mucosa (n = 20), dysplasia (n = 10), ESCC (n = 62) and special sections (n = 10) of a full-length mucosa layer from the distant margin to the cancer focus of the excised oesophagus, and 49 fresh specimens of ESCC was analysed by immunohistochemistry, western blot and real-time reverse transcription-polymerase chain reaction. Fascin expression in ESCC cell lines was also investigated. RESULTS In the immunohistochemical study, the positive rate of fascin was significantly higher in the tumour tissue than in the normal epithelium (p = 0.020), but no significant difference was shown between ESCC and dysplasia (p = 1.000). Immunostaining for fascin was only apparent in the basal layer of the normal epithelium. However, in the dysplasia, positive staining was observed in most of the heterogeneous cells from the basal layer to the granular layer of the epithelium. Fascin expression was seen to increase progressively from the normal epithelium to invasive ESCC. Up regulation of fascin was observed in 87.76% (43/49) and 77.55% (38/49) of the specimens, respectively, using western blot and real-time reverse transcription-polymerase chain reaction assays; 80% (4/5) of ESCC cell lines also expressed fascin at a high level. Furthermore, overexpression of fascin was markedly correlated with cell proliferation and lymph node metastasis. CONCLUSIONS These findings suggested that fascin was associated with the transformation and development of ESCC and implicated the potential of fascin as a novel biomarker that would allow the tumour to be identified at an early stage in high-risk individuals.

Abstract
It is well established that loss of a growth inhibitory response to transforming growth factor-beta (TGF-beta) is a common feature of epithelial cancers including esophageal cancer. However, the molecular basis for the abrogation of this key homeostatic mechanism is poorly understood. In esophageal cancer cell lines that are resistant to TGF-beta-induced growth inhibition, TGF-beta also fails to decrease transcription of c-myc despite the presence of functional signaling components. Consequently, to gain a better understanding of the mechanisms leading to resistance to TGF-beta-induced growth arrest, the basis for the inability to decrease c-myc transcription was investigated. Regardless of sensitivity to TGF-beta-induced growth arrest, TGF-beta enhanced the ability of Smad3-protein complexes to bind c-myc regulatory elements. However, in a growth inhibition-resistant esophageal cancer cell line, the Smad3-protein complexes contained the SnoN oncoprotein. Furthermore, in esophageal cancer cell lines that are resistant to TGF-beta-induced growth arrest, TGF-beta does not cause degradation of SnoN. Analyses of the effect of modulating SnoN expression in both growth inhibition-sensitive and growth inhibition-resistant cell lines showed that degradation of SnoN is a prerequisite for both TGF-beta-induced repression of c-myc transcription and growth arrest. The data indicate that SnoN-Smad3 complexes do not cause repression of c-myc transcription but rather prevent functionality of active repressor complexes. Thus, these studies reveal a novel mechanism for resistance to TGF-beta-induced growth inhibition in esophageal cancer, namely the failure to degrade SnoN. In addition, they show that SnoN can block TGF-beta repression of gene transcription.

Abstract
PURPOSE Gastroesophageal reflux disease is common and with time may be complicated by Barrett's esophagus and esophageal adenocarcinoma. Upper gastrointestinal endoscopy, including esophagoscopy, is the procedure of choice to diagnose Barrett's esophagus and other esophageal disease. The use of unsedated ultrathin esophagoscopy (UUE) has been reported by gastroenterologists in specialized endoscopy units and otolaryngologists in outpatient otolaryngology offices, but UUE has not been previously described in a primary care setting. This study examines the feasibility of office-based UUE in primary care. METHODS This study is a retrospective chart review in a university-based family medicine clinic in the southeastern United States. Charts were reviewed of 56 adult outpatients who were referred for further evaluation of reflux symptoms that persisted after at least 4 weeks of therapy with histamine(2) receptor agonists or proton pump inhibitors and who elected to undergo UUE in the primary care setting. Patient demographics, procedure indications and findings, changes in clinical management, and procedure times were recorded. RESULTS One hundred percent of patients asked to participate in UUE were willing to undergo the procedure (mean age 48.3 +/- 1.6 y, 57.1% women); 95% of the patients tolerated UUE. Barrett's esophagus was diagnosed in 5.7% (n = 3) of the patients. Mean procedure time was 5.5 +/- 1.7 min. No complications were reported in this series. CONCLUSIONS Initial data suggest that UUE is feasible in primary care, with the majority of patients tolerating the procedure. UUE may be an efficient method of examining the distal esophagus.

Abstract
Worldwide, esophageal carcinoma is a common gastrointestinal cancer with a high mortality. The incidence of adenocarcinoma of the esophagus is increasing in the western world, but squamous cell carcinoma remains dominant in the underdeveloped parts of the world. Both types of esophageal carcinoma remain equally virulent. Currently, there are no optimal preventative screening programs available and most patients present with advanced or metastatic disease. Although many options are available for improving diagnostic accuracy, a single method has not displayed significant advantages over the others. In addition, selecting a superior treatment regimen has not surfaced. Preferred resection techniques exist, but one method has not illustrated improvements in survival over the others. A lack of improved survival rates with single modality therapies has led to a multi modality approach. However, developments in neoadjuvant and adjuvant therapies have led to mixed conclusions. Collectively, past studies have not shown an optimal neoadjuvant or adjuvant regimen in terms of survival benefit. This review highlights existing staging modalities and treatment regimens for esophageal carcinoma, in an effort to illustrate the controversial nature surrounding its management.

Abstract
BACKGROUND Esophageal cancer is common in Pakistan. An attempt has been made for the first time to look at the survival data and prognostic factors associated with esophageal cancer in this region. PATIENTS AND METHODS We did a retrospective review of 263 cases seen at the Aga Khan University Hospital in Karachi. Data analysis was done using the Kaplan-Meier method and the Cox proportional hazard model. RESULTS Squamous cell carcinoma was noted in 81% of the cases, whereas adenocarcinoma was the second most common. At the time of diagnosis, early-stage disease was found in 25%, locally advanced in 41% and metastatic in 34% of all cases. Mean age at diagnosis was 56 years, with 59% males and 41% females. Survival data were available in 89 cases. Median survival was 7 months. On univariate analysis, the following factors were of prognostic significance: obstruction, histology, albumin level at diagnosis, age and platelet count. On multivariate analysis, three factors were found prognostic: presence or absence of obstruction, squamous cell carcinoma versus adenocarcinoma and platelet count. CONCLUSIONS We found that patients with squamous cell carcinoma and absence of thrombocytopenia and obstruction had a better overall survival. However, this is a limited retrospective analysis; we therefore recommend that these prognostic factors be evaluated in larger studies.

Abstract
AIM The detailed review of patterns of failure in this report was undertaken to identify the continuing obstacles to the successful management of oesophageal cancer, and to establish whether there is a case to compare definitive chemo-radiation (Def-CR) and surgery for patients with squamous cancer in a randomized controlled trial. MATERIALS AND METHODS First and subsequent sites of failure were reviewed in 274 patients treated with Def-CR using two cycles of cisplatin, infusional fluorouracil and 60 Gy; and 92 patients with limited chemo-radiation (CR), using one cycle and 35 Gy, followed by surgery (CR-Surg). All were treated on prospective non-randomized trials run by the Trans-Tasman Radiation Oncology Group between 1985 and 1999. Failure patterns were analysed using competing risks methodology, and pre-treatment variables predicting survival were identified by proportional hazards modelling. RESULTS Site, stage, performance status and gender were independently predictive of survival following Def-CR. Local failure was evident in 42.3% of patients, but distant failure in isolation occurred in an additional 18.1%. Lowest rates of local and distant failure at 5 years (29.9% and 26%) occurred in patients with squamous cancer (SCC) located in the upper-third, whose 5-year survival was also the most favourable (49.2%). Survival was least favourable in patients with adenocarcinoma (AC) in the lower two-thirds (18.1%) due to higher rates of local (51.5%) and distant (36.1%) failure. Local failure occurred in 31.5% of patients undergoing CR-Surg but distant failure in isolation was observed in a further 34.7%. Outcomes were least favourable in patients with AC of the lower-third in whom 57.7% failed distantly and 5-year survival was 3.8%. Response to pre-operative chemo-radiation was also strongly predictive of outcome. Patients with no residual cancer in the resection specimen had the lowest rates of local (0%) and distant (16.7%) failure and the best survival (64.9%). Survival in patients with residual cancer in nodes, however, was extremely poor (3.5%) with distant failure occurring in 66.7%. CONCLUSION The concurrent administration of chemotherapy with radiotherapy seems to have improved loco-regional control and has exposed distant failure as an obstacle to further improvements in outcome. Site, histological subtype, gender and response to chemo-radiation may predict biological differences in oesophageal cancer (OC) that influence outcome. A good case for a randomized comparison between Def-CR and CR-Surg in patients with SCC in the lower two-thirds exists.

Abstract
A patient with a previous diagnosis of lymphoma showed signs of dysphagia. Endoscopy found a lesion of the esophagus. Brush cytology and biopsy sampling were accomplished. The biopsy showed inflammation and granulation tissue but no tumor. The cytology specimen, however, was diagnostic of lymphoma. This case emphasizes the need for obtaining cytologic specimens concurrently with biopsies of esophageal lesions.

Abstract
BACKGROUND The effects of multimodality treatment on the survival of patients with esophageal carcinoma are unclear. The authors performed a prospective, Phase II study to assess the long-term results of chemotherapy plus radiotherapy (RT) on patients with esophageal squamous cell carcinoma. METHODS Of 106 consecutive patients who were recruited between 1985 and 1992, 101 patients were evaluable. Cisplatin (100 mg/m2 per day) on Day 1 and fluorouracil (1000 mg/m2 per day) on Days 1-4 were given for two cycles, with concomitant RT (30 grays [Gy] in 15 fractions) over 19 days. Patients with potentially resectable tumors were then assessed for curative surgery; the other patients received two more courses of chemotherapy and further RT (20 Gy in 10 fractions). RESULTS Of 40 patients who were candidates for surgery, 32 patients underwent surgery, and 24 patients had complete resection; 8 patients (25%) had no residual tumor in the specimen, and 12 patients (37%) had microscopic foci only. Surgical mortality was high (22%). Of 61 nonsurgical patients, 37 patients (61%) achieved complete clinical remission, and 14 patients (23%) achieved partial remission. The median survival for the entire series was 15 months (range, 1-136 months). The overall survival rate was 22% at 5 years and 12% at 10 years. At 10 years, freedom from disease progression was similar in the two groups (24%), whereas the median survival (22 months vs. 12 months) and the overall survival rates (17% vs. 9%) were better in nonsurgical patients compared with surgical patients, respectively, probably in relation to high surgical mortality. The larynx was preserved in 28% of 32 patients with cervical disease sites, with a 10-year disease free survival rate of 31%. Three deaths were attributed to nonsurgical treatments. CONCLUSIONS Careful multidisciplinary pretreatment evaluation can identify patients who are ineligible for surgery without compromising long-term results. For patients with inoperable disease, chemoradiotherapy can produce relatively good long-term results. The combined approach without surgery can permit laryngeal preservation in a useful fraction of patients.
