Gastrointestinal malignancies at five regional referral hospitals in Uganda.	BACKGROUND: There is a paucity of published data regarding the trend and distribution of gastrointestinal malignancies in Uganda. OBJECTIVES: To study the trend and distribution of gastrointestinal malignancies over a 10 year period at five regional referral hospitals in Uganda. METHODS: Patient's charts with histologically confirmed diagnoses of gastrointestinal malignancies for the period 2002-2011 were identified. Case information, which included age at diagnosis, sex, and year of diagnosis, primary anatomic site of the tumour and hospitals attended, was retrospectively abstracted. Patient's clinical and demographic features were compared. RESULTS: Oesophageal cancer was the most common (28.8%) followed by liver (25.8%), stomach (18.4%) and colorectal (14.3%). The mean age at diagnosis for all the cancers was not significantly different in both sexes 54.1, (SD16.1) versus 53.6, (SD 14.7). The highest mean annual number of cases of oesophageal and stomach cancers was 21.8, (SD 15.5) and 16.6, (SD 13.0) respectively from Mbarara Hospital; Lacor had the highest mean annual number of liver cancer cases (21, SD 17.7) followed by Mbale (11.4, SD 8.3). The mean annual number of colorectal cancers was highest in Mbale Hospital (10.3, SD 8.1) followed by Lacor (4.9, SD 3.9). The distribution of oesophageal, liver, stomach and colorectal cancers diagnosed per year across the five referral hospitals was different, P<0.001. CONCLUSION: Oesophageal, liver, stomach and colorectal cancer remain the most common gastrointestinal malignancies and their rate is increasing in Uganda. There is a need for awareness, endoscopic and radiological assessment of symptomatic individuals and a need for screening of high index patients.	esophagus
Complications After Esophagectomy Are Associated With Extremes of Body Mass Index.	BACKGROUND: Body mass index (BMI) is not routinely taken into consideration for risk stratification prior to esophagectomy. Extremes of BMI are associated with adverse surgical outcomes in a variety of surgical specialties. We assessed the relationship of BMI to outcomes after esophagectomy for cancer. METHODS: Patients in the Society of Thoracic Surgeons General Thoracic Surgery Database (2009 to 2016) who underwent elective esophagectomy for cancer were selected for analysis. Open and minimally invasive approaches were included. Complications were categorized based on the Esophagectomy Complications Consensus Group recommendations. Multivariable logistic regression was used to adjust for confounding variables. RESULTS: We evaluated 9,389 patients grouped by BMI: underweight (<18.5 kg/m(2); 3%), normal (18.5 to 24.9 kg/m(2); 32%), overweight (25 to 29.9 kg/m(2); 36%), obese I (30 to 34.9 kg/m(2); 19%), obese II (35 to 39.9 kg/m(2); 7%), and obese III (≥40 kg/m(2); 3%). Most patients underwent open Ivor Lewis (33%), open transhiatal (23%), or minimally invasive Ivor Lewis (22%) approaches. The operative mortality rate was 3.4%; the frequency of complications by category ranged from 4% to 28%. On multivariable analysis, overall differences were identified among BMI categories for 7 out of 9 complication types. Underweight and obese III categories were associated with increased risk. In contrast, overweight and obese I BMI were associated with decreased risk for most complication types. CONCLUSIONS: BMI is associated with postoperative complications after esophagectomy. Postoperative risk assessment and prehabilitation regimens should be adjusted accordingly when planning an esophagectomy for a patient with very low or very high BMI.	esophagus
Induction of Thioredoxin-Interacting Protein by a Histone Deacetylase Inhibitor, Entinostat, Is Associated with DNA Damage and Apoptosis in Esophageal Adenocarcinoma.	"In 2017, an estimated 17,000 individuals were diagnosed with esophageal adenocarcinoma (EAC), and less than 20% will survive 5 years. Positron emission tomography avidity is indicative of high glucose utilization and is nearly universal in EAC. TXNIP blocks glucose uptake and exhibits proapoptotic functions. Higher expression in EAC has been associated with improved disease-specific survival, lack of lymph node involvement, reduced perineural invasion, and increased tumor differentiation. We hypothesized that TXNIP may act as a tumor suppressor that sensitizes EAC cells to standard chemotherapeutics. EAC cell lines and a Barrett epithelial cell line were used. qRT-PCR, immunoblot, and immunofluorescence techniques evaluated gene expression. TXNIP was stably overexpressed or knocked down using lentiviral RNA transduction techniques. Murine xenograft methods examined growth following overexpression of TXNIP. Apoptosis and DNA damage were measured by annexin V and γH2AX assays. Activation of the intrinsic apoptosis was quantitated with green fluorescence protein-caspase 3 reporter assay. In cultured cells and an esophageal tissue array, TXNIP expression was higher in Barrett epithelia and normal tissue compared with EAC. Constitutive overexpression of TXNIP decreased proliferation, clonogenicity, and tumor xenograft growth. TXNIP overexpression increased, whereas knockdown abrogated, DNA damage and apoptosis following cisplatin treatment. An HDAC inhibitor, entinostat (currently in clinical trials), upregulated TXNIP and synergistically increased cisplatin-mediated DNA damage and apoptosis. TXNIP is a tumor suppressor that is downregulated in EACC. Its reexpression dramatically sensitizes these cells to cisplatin. Our findings support phase I/II evaluation of ""priming"" strategies to enhance the efficacy of conventional chemotherapeutics in EAC. Mol Cancer Ther; 17(9); 2013-23. ©2018 AACR."	esophagus
Role of self-expanding stents in the treatment of intrathoracic dehiscence after Ivor Lewis esophagectomy.	INTRODUCTION: The role that self-expanding stents play in the treatment of dehiscence after transthoracic esophagectomy is not well defined and controversial. Our aim is to describe the experience in a tertiary care hospital using these devices for treating dehiscence after Ivor Lewis esophagectomy. METHODS: Descriptive observational study of patients who suffered anastomotic dehiscence after a transthoracic esophagectomy, and especially those treated with stents, in the period between 2011-2016 at our hospital. RESULTS: Ten patients (11.8%) presented anastomotic dehiscence. Eight patients received stents, one of them died due to causes unrelated to the device. Stent migration was observed in one case, and the devices were maintained an average of 47.3 days. The stent was not effective only in one patient who suffered early dehiscence due to acute ischemia of the stomach. The two patients who did not receive stents died after reoperation. CONCLUSIONS: Stents are safe and effective devices that did not associate mortality in our series. They are especially indicated in intermediate or late-onset dehiscence and in fragile patients. The use of stents, together with mediastinal and pleural drainage, avoid reoperations with morbidity and mortality. Therefore, stents should be part of the usual therapeutic arsenal for the resolution of most suture dehiscences after Ivor Lewis esophagectomy. Randomized prospective studies would help to more precisely determine the role played by these devices in the treatment of dehiscence after transthoracic esophagectomy.	esophagus
Association between Dietary Vitamin E Intake and Esophageal Cancer Risk: An Updated Meta-Analysis.	Epidemiological studies have provided ambiguous evidence on the association between vitamin E and esophageal cancer risk. To resolve this controversy, we performed this meta-analysis. The literature was searched by using Excerpta Medica Database (EMBASE), PubMed, the Web of Science, and the Cochrane Library from the inception to April 2018. A random effect model was utilized to calculate the odds ratio (OR) with the 95% confidence interval (95% CI). Twelve articles reporting 14 studies involving 3013 cases and 11,384 non-cases were included. By comparing the highest category with the lowest category of dietary vitamin E intake, we found that dietary vitamin E intake was inversely related to esophageal cancer risk (OR = 0.47, 95% CI: 0.36⁻0.60). Subgroup analysis revealed that dietary vitamin E intake had a significantly negative association with both the esophageal squamous cell carcinoma risk (OR = 0.29, 95% CI: 0.18⁻0.44) and the esophageal adenocarcinoma risk (OR = 0.66, 95% CI: 0.49⁻0.88). No study significantly affected the findings in the sensitivity analysis. Publication bias was discovered, however, the OR (95% CI) remained unchanged after the trim-and-fill analysis. This meta-analysis showed that the higher dietary vitamin E intake is associated with a lower esophageal cancer risk. However, the association still needs to be upheld by more large-scaled randomized controlled trials and prospective studies.	esophagus
Cancer-Associated Fibroblasts Affect Intratumoral CD8(+) and FoxP3(+) T Cells Via IL6 in the Tumor Microenvironment.	Purpose: Cancer-associated fibroblasts (CAFs) in the tumor microenvironment (TME) play a central role in tumor progression. We investigated whether CAFs can regulate tumor-infiltrating lymphocytes (TILs) and their role in tumor immunosuppression.Experimental Design: A total of 140 cases of esophageal cancer were analyzed for CAFs and CD8(+) or forkhead box protein 3 (FoxP3(+)) TILs by IHC. We analyzed cytokines using murine or human fibroblasts and cancer cells. Murine-derived fibroblasts and cancer cells were also inoculated into BALB/c or BALB/c-nu/nu mice and the tumors treated with recombinant IL6 or anti-IL6 antibody.Results: CD8(+) TILs and CAFs were negatively correlated in intratumoral tissues (P < 0.001), whereas FoxP3(+) TILs were positively correlated (P < 0.001) in esophageal cancers. Cocultured Colon26 cancer cells and fibroblasts resulted in accelerated tumor growth in BALB/c mice, along with decreased CD8(+) and increased FoxP3(+) TILs, compared with cancer cells alone. In vitro, IL6 was highly secreted in both murine and human cancer cell/fibroblast cocultures. IL6 significantly increased Colon26 tumor growth in immune-competent BALB/c (P < 0.001) with fewer CD8(+) TILs than untreated tumors (P < 0.001), whereas no difference in BALB/c-nu/nu mice. In contrast, FoxP3(+) TILs increased in IL6-treated tumors (P < 0.001). IL6 antibody blockade of tumors cocultured with fibroblasts resulted not only in regression of tumor growth but also in the accumulation of CD8(+) TILs in intratumoral tissues.Conclusions: CAFs regulate immunosuppressive TIL populations in the TME via IL6. IL6 blockade, or targeting CAFs, may improve preexisting tumor immunity and enhance the efficacy of conventional immunotherapies. Clin Cancer Res; 24(19); 4820-33. ©2018 AACR.	esophagus
Expression of Transcription Factor 21 (TCF21) and Upregulation Its Level Inhibits Invasion and Metastasis in Esophageal Squamous Cell Carcinoma.	BACKGROUND Transcription factor 21 (TCF21), a member of the class A of basic helix-loop-helix family, has been widely identified as a tumor suppressor. Growing evidence has demonstrated the downregulation of TCF21 in distinct cancers. The aim of this study was to explore the expression and biological functions of TCF21 in esophageal squamous cell carcinoma (ESCC). MATERIAL AND METHODS TCF21 expression in esophageal cancer cell lines and carcinomas tissues were detected, and its associations with clinical characteristics were analyzed. We carried out this study of biological functions and underlying mechanisms using TE10 and KYSE510 cell lines. RESULTS TCF21 mRNA and protein expression were both downregulated in esophageal cancer tissues compared with adjacent normal tissues. Low expression of TCF21 was closely correlated with N stage. In Kaplan-Meier survival analysis, patients with lower TCF21 expression had poorer prognosis. Overexpression of TCF21 greatly inhibited the proliferation, migration, and invasion in both TE10 and KYSE510 cell lines. Furthermore, mechanistic studies showed that with TCF21 gene overexpressed, the expression of tumor suppressor Kiss-1 was upregulated and epithelial-mesenchymal transition (EMT) related proteins (E-cadherin, N-cadherin, Snail, Twist, and Vimentin) which participate in cancer cell invasion and metastasis, were reversed. CONCLUSIONS TCF21 is downregulated in ESCC, and its low expression is closely correlated with N stage and predicts a poor prognosis. TCF21 functions as a tumor suppressor in ESCC progression, and enhancement of its expression levels may be partly through promoting Kiss-1 expression to reverse EMT by modulating EMT-related gene expression. Thus, TCF21 can potentially be used as a treatment target for ESCC.	esophagus
Health utility scores from EQ-5D and health-related quality of life in patients with esophageal cancer: a real-world cross-sectional study.	Esophageal cancer and its treatment can cause serious morbidity/toxicity. These effects on health-related quality of life (HRQOL) can be measured using disease-specific scales such as FACT-E, generic scales such as EQ-5D-3L, or through symptoms. In a two-year cross-sectional study, we compared HRQOL across esophageal cancer patients treated in an ambulatory clinic and across multiple disease states, among patients with all stages of esophageal cancer. Consenting patients completed FACT-E, EQ-5D, a visual analog scale, and patient reported (PR)-ECOG. Symptom complexes were constructed from FACT-E domains. Responses were categorized by disease state: pre-, during, and post-treatment, surveillance, progression, and palliative chemotherapy. Spearman correlation and multivariable linear regression characterized these associations. In total, 199 patients completed 317 questionnaires. Mean FACT-E and subscale scores dropped from baseline through treatment and recovered during post-treatment surveillance (P < 0.001); EQ-5D health utility scores (HUS) displayed a similar pattern but with smaller differences (P = 0.07), and with evidence of ceiling effect. Among patients with stage II/III esophageal cancer, mean EQ-5D HUS varied across disease states (P < 0.001), along with FACT-E and subscales (P < 0.001). Among patients with advanced disease, there was no significant difference between baseline and on-treatment total scores, but improved esophageal cancer-specific scales were noted (P = 0.003). Strong correlation was observed between EQ-5D and FACT-E (R = 0.73), along with physical and functional subscales. In addition, the association between FACT-E and EQ-5D HUS was maintained in a multivariable model (P < 0.001). We interpret these results to suggest that in a real-world clinic setting, FACT-E, EQ-5D HUS, and symptoms were strongly correlated. Most HRQOL and symptom parameters suggested that patients had worse HRQOL and symptoms during curative therapy, but recovered well afterwards. In contrast, palliative chemotherapy had a neutral to positive impact on HRQOL/symptoms when compared to their baseline pre-treatment state.	esophagus
Surgery combined with radio-chemotherapy for esophageal mucoepidermoid carcinoma: A case report.	RATIONALE: Primary mucoepidermoid carcinoma (MEC) of the esophagus is a rare type of malignant neoplasm. Its morphology resembles that of MEC of the salivary glands. It is characterized by a diffuse mixture of squamous and mucus-secreting glandular carcinoma cells. Due to the low incidence of esophageal MEC, the biological behavior and treatment of this tumor have not been well studied. PATIENT CONCERNS: In this case report, we describe a case of a 59-year-old man who presented with difficulty in swallowing. Iohexol swallowing revealed a malignant-appearing structure in the inferior-thoracic region. DIAGNOSES: Biopsy of the lesion under endoscopy demonstrated a mucoepidermoid carcinoma of the esophagus. INTERVENTIONS: We performed esophagectomy, esophagogastrostomy through the esophageal bed and 2-field lymphadenectomy. Histopathological analysis of the tumor revealed histological characteristics typical of an esophageal MEC. Radio-chemotherapy was administered to this patient. OUTCOMES: Seventeen months after surgery, an esophageal computed tomography (CT) scan revealed that the wall of esophagus was evenly thickened. However, endoscopic assessment revealed no evidence of recurrence. Further CT scans at 19 and 31 months after surgery also showed a thickened esophageal wall, although endoscopic assessment at 31 months still revealed no esophageal stricture and no evidence of recurrence. The patient is alive with no dysphagia and no evidence of recurrence for over 39 months. LESSONS: There is little evidence of effective treatment nor guidelines for treatment of esophageal MEC. Although the general prognosis of esophageal MEC is poor, comprehensive treatment of surgery and radio-chemotherapy appeared to be effective in this case. Radio-chemotherapy is a possible treatment option that was shown to have acceptable short-term effects.	esophagus
Pain is associated with continuing depression in cancer survivors.	Depression is common but under-diagnosed in cancer survivors. This study characterized depressive symptoms over one year in cancer survivors and examined disease-related and psychosocial predictors of depression severity. Participants (n = 122; M(age) 65.33, SD = 9.17, 98.4% male) with head and neck, esophageal, gastric, or colorectal cancers were recruited through tumor registries at two regional Veterans Administration Medical Centers. Self-report measures assessing depressive symptoms (PHQ-9), combat-related PTSD symptoms (PC-PTSD), and health-related quality of life (PROMIS) were administered at six, twelve, and eighteen months after diagnosis. Symptoms consistent with major depression were endorsed by approximately one-quarter of the sample at six (24%), twelve (22%), and eighteen (26%) months post diagnosis, with 12% of participants reporting consistently significant depressive symptoms. In multivariate modeling, significant predictors of depression at eighteen months included prior depressive symptoms (β = .446, p < 0.001) and current pain interference (β = .231, p = .003). The present findings suggest that major depression is common and persistent one year following cancer diagnosis. Attention to pain management and routine monitoring of mood symptoms is critical to reducing risk of depression in cancer survivors.	esophagus
Fully vs. partially covered selfexpandable metal stent for palliation of malignant esophageal strictures: a randomized trial (the COPAC study).	BACKGROUND: Covered esophageal self-expandable metal stents (SEMSs) are currently used for palliation of malignant dysphagia. The optimal extent of the covering to prevent recurrent obstruction is unknown. Therefore, we aimed to compare fully covered (FC) versus partially covered (PC) SEMSs in patients with incurable malignant esophageal stenosis. METHODS: In this multicenter randomized controlled trial, 98 incurable patients with dysphagia caused by a malignant stricture of the esophagus or cardia were randomized 1:1 to an FC-SEMS or PC-SEMS. The primary outcome was recurrent obstruction after endoscopic SEMS placement. Secondary outcomes were technical and clinical success, adverse events, and health-related quality of life (HRQoL). Patients were followed until 6 months after SEMS placement or to SEMS removal, second SEMS insertion, or death, whichever came first. RESULTS: Recurrent obstruction after SEMS placement was similar for both types of stents: 19 % for FC-SEMSs and 22 % for PC-SEMSs (P = 0.65). The times to recurrent obstruction did not differ. The frequency of adverse events was similar between the two groups, with major adverse events occurring in 38 % and 47 % of patients for FC-SEMSs and PC-SEMSs, respectively (P = 0.34). No significant differences were seen in technical success, improvement of dysphagia, and HRQoL. Proximal esophageal stenosis and female sex were independently associated with recurrent obstruction and/or major adverse events. CONCLUSIONS: Esophageal FC-SEMSs did not reveal a lower recurrent obstruction rate compared with PC-SEMSs in the palliative management of malignant dysphagia.	esophagus
Effects of food insecurity on the women esophageal cancer in the Zanjan Province.	BACKGROUND: Nowadays one of the principal challenges of any country is improving the chronic disease and cancers. One of the most important of cancers is esophageal cancer in Iran. No doubt, esophageal cancer is an outcome of the interaction and combination of different factors. Cancer of the esophagus is one of the most common causes of death in adults (especially women) in Iran, where the incidence of this cancer is among the highest in the world. OBJECTIVE: The main aim of this cross-sectional study was to test the hypothesis that food insecurity could create esophageal cancer among women in Iran (Zanjan Province). METHODS: The method of this paper has been based on the analytical and descriptive research using fuzzy cognitive maps (FCMs) method. The subjects were 580 women aged 40-70 years (150 women have esophageal cancer), and they are selected randomly in the Zanjan Province of Iran. RESULTS: The food insecurity (such as hunger and hidden hunger) in the Zanjan Province, according to the 24 h food-recall questionnaire was 23% and 38%, respectively. Only 39% of the study population was secure in terms of having access to all key nutrients. The accuracy of the questionnaire for screening for hunger in the population was 88.78%, respectively, and the corresponding value for hidden hunger was 83.4%. The average value of esophageal cancer predicted using fuzzy cognitive maps is equal to 75.43% (for 36 months). CONCLUSION: Our findings showed an association of food insecurity and body mass index (BMI) in the study population. Food insecurity increased the rate of underweight and decreased the rates of overweight and obesity.	esophagus
Practical value of identifying circulating tumor cells to evaluate esophageal squamous cell carcinoma staging and treatment efficacy.	BACKGROUND: This study was conducted to investigate the correlation between clinicopathological features and post-therapeutic response in esophageal squamous cell carcinoma (ESCC) patients. Peripheral blood circulating tumor cells (CTCs) expressing epithelial-mesenchymal transition markers were identified. METHODS: Peripheral blood samples were collected from 71 patients with newly diagnosed ESCC and 40 healthy volunteers. CTCs were isolated using CanPatrol CTC enrichment technology. RNA-fluorescent in situ hybridization was used to phenotype the CTCs on the basis of epithelial and/or mesenchymal markers. RESULTS: The median mesenchymal CTC counts in 71 patients were: 0 in 19 stage I patients, 2 in 31 stage II, and 3 in 21 stage III/IV. The overall diagnostic performance of total CTCs to correctly identify ESCC patients was 0.991. We observed a correlation between increases in tumor size or advanced stage and an increased number of mesenchymal CTCs (P < 0.05). Thirty-nine patients were administered two cycles of neoadjuvant chemotherapy and their therapeutic response was evaluated: 2 complete response, 20 partial response, 13 stable disease, and 4 progressive disease. After treatment, the positive rate of mesenchymal CTCs was 70.6% in the progressive and stable disease group versus 36.4% in the complete and partial response group (P = 0.05). CONCLUSION: The results showed that mesenchymal CTC count is related to ESCC clinical stage and the efficacy of neoadjuvant chemotherapy.	esophagus
