RESUMO
BACKGROUND: Esophagectomy for cancer strongly impairs quality of life. The aim of this trial was to evaluate the effect of the nutritional and respiratory counseling on postoperative quality of life. METHODS: At hospital discharge, patients were randomized into four groups receiving respectively: nutritional and respiratory counseling, nutritional counseling alone, respiratory counseling alone, or standard care. The main endpoint was the impairment in quality of life in the first month after surgery. Linear mixed effect models were estimated to assess mean score differences (MDs) in quality of life scores. RESULTS: Patients receiving nutritional counseling reported less appetite loss (MD - 17.7, 95% CI - 32.2 to -3.3) than those not receiving nutritional counseling at 1 month after surgery. Dyspnea was similar between patients receiving vs. those not receiving respiratory counseling (MD - 3.1, 95% CI - 10.8 to 4.6). Global quality of life was clinically similar between patients receiving vs. those not receiving nutritional counseling over time (MD 0.9, 95% CI - 5.5 to 7.3), as well as in patients receiving vs. those not receiving respiratory counseling over time (MD 0.7, 95% CI - 5.9 to 7.2). CONCLUSIONS: Intensive postoperative care does not affect global quality of life even if nutritional counseling reduced appetite loss.

BACKGROUND: The objective of this study was to explore the association between fresh fruit consumption and long-term risk of upper gastrointestinal cancer (UGI) in the Linxian Dysplasia Nutrition Intervention Trial (NIT) cohort. METHODS: A cohort of 3318 subjects with esophageal squamous dysplasia participated in the Linxian Dysplasia NIT in May 1985 and were followed up until 30 September 2015. Demographic characteristics, lifestyle, and history of diseases were collected at the baseline. The primary endpoint was death from esophageal squamous cell carcinoma (ESCC), gastric cardia carcinoma (GCC), and gastric noncardia carcinoma (GNCC). Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were estimated using the Cox proportional hazard model. RESULTS: In the 30-year follow-up, a total of 541 ESCC, 284 GCC, and 77 GNCC deaths occurred. Relative to those who never or rarely consumed fresh fruit, the risk of ESCC mortality in participants who consumed fresh fruit more than 12 times/year were significantly decreased by 37.3% (HR = 0.63, 95% CI: 0.49-0.81). In the subgroup analyses, significantly protective effects on ESCC mortality were observed especially in females (HR = 0.59, 95% CI: 0.40-0.89), non-smokers (HR = 0.67, 95% CI: 0.48-0.94), and nondrinkers (HR = 0.69, 95% CI: 0.51-0.93). CONCLUSIONS: Consuming fresh fruit more than 12 times/year may reduce the long-term risk of ESCC mortality in this dysplasia population, particularly in females, non-smokers, and nondrinkers. Future studies are needed to confirm these findings.

BACKGROUND: The effects of dietary factors on prognosis of esophageal cancer remain unclear. This systematic review and meta-analysis aimed to assess the association between dietary intake and the risk of mortality among patients with esophageal cancer. METHODS: Six electronic databases (PubMed, Web of Science, OVID, ProQuest, CNKI and Wanfang) were searched for studies published up to Oct. 2019 that examined the association between dietary intake and all-cause mortality, esophageal cancer-specific mortality and esophageal cancer recurrence. The pooled hazard ratio (HR) with 95% confidence interval (CI) were derived by comparing the highest with the lowest categories of each dietary item and by using random effect models. RESULTS: A total of 15 cohort studies were included in this study and all reported pre-diagnosis dietary exposure; two focused on dietary folate, 12 on alcohol consumption and three on other dietary components (sugary beverages, phytochemicals and preserved vegetables). When comparing the highest with the lowest categories, dietary folate intake was associated with a reduced risk of esophageal cancer-specific mortality in patients with esophageal squamous cell carcinoma (HR: 0.41, 95% CI: 0.25-0.69), with low heterogeneity (I2 = 0%, P = 0.788). When comparing the highest with the lowest categories of alcohol consumption, alcohol consumption was associated with an increased risk of all-cause mortality in patients with esophageal squamous cell carcinoma (HR: 1.29, 95% CI: 1.07-1.55; heterogeneity: I2 = 53%, P = 0.030), but this increased risk was not significant in patients with esophageal adenocarcinoma (HR = 1.05, 95% CI: 0.84-1.32). CONCLUSIONS: This review with pre-diagnostic dietary exposure showed that dietary folate intake was associated with a reduced risk of mortality of esophageal squamous cell carcinoma, whereas alcohol consumption was associated with an increased risk. More studies are needed to investigate effect of dietary factors, especially post-diagnosis dietary consumption, on esophageal cancer prognosis.

PURPOSE: Oesophageal cancer (OC) impacts nutritional status and outcomes. This study aims to benchmark the current nutrition management of patients with OC against best practice recommendations, identify critical points in the treatment trajectory where nutritional status is compromised, service gaps and opportunities for improvement. METHODS: A retrospective audit collected demographic, medical and nutritional data from medical records of patients who received curative treatment for OC at a tertiary referral hospital in Sydney, Australia. RESULTS: Thirty-seven patient records were audited over the time period. Twenty-nine patients underwent nutrition screening on admission to the service. Eighteen out of 25 patients receiving neoadjuvant radiation therapy, all patients during surgical admission, and only 19 patients at postsurgical discharge were seen by a dietitian. All patients received tube feeding post-operatively; however, initiation within 24 h only occurred for 14 patients. Weight significantly declined over the course of treatment (p < 0.001), whilst malnutrition during surgical admission (p = 0.004) and postsurgical discharge (p = 0.038) were both associated with significantly higher unplanned readmissions. CONCLUSIONS: Best practice recommendations were met for aspects of the immediate post-operative period; however, service gaps remain during pre-operative and post-discharge care. Findings from this study indicate that nutritional care is inconsistent across different treatment stages, and malnutrition impacts negatively on unplanned readmission. Research is needed to address evidence-practice gaps, assess appropriateness of recommendations and provide evidence for models of care during multimodality treatments and across different services.

Two illustrative applications are presented of Bayesian clinical trial designs that make adaptive subgroup-specific decisions based on elicited utilities of patient outcomes to quantify risk-benefit trade-offs. The first design is for a randomized trial to evaluate effects of nutritional prehabilitation on post-operative morbidity in esophageal cancer patients undergoing surgery. The second design is for a dose-finding trial of natural killer cells to treat advanced hematologic malignancies, with five time-to-event outcomes. Each design is based on a Bayesian hierarchical model that borrows strength between subgroups. Computer simulation is used to evaluate each design's properties, including comparison to a simpler design ignoring treatment-subgroup interactions. The simulations show that accounting prospectively for treatment-subgroup interactions yields designs with very desirable properties, is greatly superior to a simplified comparator design that ignores subgroups if treatment-subgroup interactions actually exist, and each design is robust to deviations from the assumed underlying model.

Objective: Prognostic nutritional index (PNI) can be used for survival predication in patients with esophageal cancer (EC). However, the prognostic value of PNI in EC is inconclusive in accordance to the literature. This meta-analysis aimed to evaluate the prediction value of PNI in EC.Methods: Studies focus on the association of PNI and EC were retrieved from the electronic databases. Standard meta-analysis methods were used for data evaluation.Results: Our search yield 12 studies, involving 3118 patients with EC for data analysis. The pooled data suggested that low PNI was correlated with worse overall survival (hazard ratio (HR) = 1.29, 95% confidence interval (CI):1.11-1.50, P = 0.001) and cancer-specific survival (HR = 2.18, 95% CI: 1.68-2.83, P < 0.0001). Moreover, lower PNI was associated with unfavorable prognostic factors (the presence of lymph node metastasis, deeper tumor invasion and advanced TNM stages).Conclusion: The lower PNI was correlated with unfavorable prognostic factor and poor prognosis in patients with EC.

Introdução: A presença de um nutricionista no setor de radioterapia objetiva a recuperação e a manutenção do estado nutricional dos pacientes. Objetivo: Comparar os resultados do aconselhamento nutricional diário com o aconselhamento nutricional semanal em pacientes com câncer de cabeça, pescoço e esôfago em tratamento radioterápico. Método: Foram selecionados 29 pacientes para o estudo e separados aleatoriamente em dois grupos. O grupo intervenção recebeu aconselhamento nutricional diariamente. O grupo padrão recebeu aconselhamento nutricional semanalmente. De ambos os grupos, foram aferidos peso corporal, circunferência braquial ou de panturrilha, avaliação subjetiva global produzida pelo próprio paciente (ASG-PPP) e cálculo do recordatório alimentar diário. Resultados: A maioria dos participantes era do sexo masculino (80%), com média de idade de 62,7 ± 26 anos. A terapia nutricional oral foi necessária para 48% dos indivíduos e, ao final do tratamento, 60% estavam em uso de nutrição enteral. A perda de peso média no grupo intervenção foi de 1,89 ± 2,58 Kg comparada à perda média de peso no grupo padrão de 9,92 ± 6,68 Kg (p=0,017). Metade dos pacientes do grupo intervenção, que iniciaram o tratamento categorizados pela ASG-PPP em A, finalizou o tratamento nessa mesma categoria (41,7%). Mais de 40% dos pacientes do grupo intervenção alcançaram as necessidades calóricas durante cinco semanas do tratamento. Conclusão: Encontraram-se resultados significativos para menor perda de peso em pacientes com aconselhamento nutricional diário que podem futuramente ser precursores de diretrizes que orientem e direcionem profissionais a condutas específicas aos pacientes com esse perfil.
Introduction: The presence of a nutritionist in the radiotherapy sector intends to recover and maintain the nutritional status of the patients. Objective: To compare the results of daily nutritional counseling with weekly nutritional advising for patients with head, neck and esophagus cancer in radiotherapy treatment. Method: 29 patients were assigned to the study and randomly divided into two groups. The intervention group received nutritional advice daily. The standard group received weekly nutritional counseling. For both groups, body weight, calf or calf circumference, global subjective evaluation produced by the patient (ASG-PPP) and calculation of the daily dietary recall were measured. Results: The majority of the participants were male (80%), mean age 62.7 ± 26 years. Oral nutrition therapy was required treatment 60% were in use of enteral nutrition. The mean weight loss in the intervention group was 1.89 ± 2.58 kg compared to the mean weight loss in the standard group of 9.92 ± 6.68 kg (p <0.001). Half of the patients in the intervention group who began treatment categorized by ASG-PPP in A, finished treatment in the same category (41.7%). More than 40% of patients in the intervention group achieved caloric needs during five weeks of treatment. Conclusion: This study found significant results for lower weight loss in patients with daily nutritional counseling. These results may in the future be precursors of guidelines that steer and direct professionals to specific conducts to patients with this profile.

PURPOSE: To explore the influence of postoperative enteral nutrition combined with adjuvant radiotherapy on inflammatory response, nutrition, healing and prognosis in patients undergoing radical surgery for esophageal carcinoma. METHODS: A total of 114 patients with esophageal carcinoma receiving radical surgery from January 2016 to July 2017 composed the observation group and randomly divided into control group (n=57) and study group (n=57). Patients in the control group were given routine nutritional support after surgery, while those in the study group received enteral nutrition after surgery. The changes in inflammatory response and nutritional level, healing and prognosis in the two groups of patients before and after treatment were compared and analyzed. RESULTS: After treatment, the levels of serum hypersensitive C-reactive protein (hs-CRP) and prostaglandin E (PGE) of patients were decreased in both the control group and study group, and they were lower in the study group than those in the control group, while the levels of serum pro-albumin (PA) and albumin (ALB) of patients in the study group were higher than those in the control group (p<0.05). The postoperative wound healing time, total length of hospital stay, postoperative first exhaust time and defecation time in the study group were shorter than those in the control group (p<0.05). The total incidence rate of postoperative complications of patients in the study group was lower than that in the control group (p<0.05). CONCLUSION: The application of postoperative enteral nutrition combined with adjuvant radiotherapy in patients subjected to radical surgery for esophageal carcinoma can suppress systemic inflammatory response, improve the nutritional condition, promote postoperative wound healing and improve prognosis and therefore it is worthy of promotion in clinical practice.

BACKGROUND: Higher levels of circulating 25-hydroxyvitamin D [25(OH)D] are associated with longer survival in several cancers, but the results have differed across cancer sites. The association between serum 25(OH)D levels and overall survival (OS) time in esophageal adenocarcinoma remains unclear. METHODS: We utilized serum samples from 476 patients with primary esophageal adenocarcinoma, recruited from Massachusetts General Hospital (Boston, MA) between 1999 and 2015. We used log-rank tests to test the difference in survival curves across quartiles of 25(OH)D levels and extended Cox modeling to estimate adjusted HRs. We tested for interactions between clinical stage or BMI on the association between 25(OH)D and OS. We additionally performed sensitivity analyses to determine whether race or timing of blood draw (relative to treatment) affected these results. RESULTS: We found no evidence that survival differed across quartiles of 25(OH)D (log rank P = 0.48). Adjusting for confounders, we found no evidence that the hazard of death among the highest quartile of 25(OH)D (quartile 1) differed from any other quartile [quartile 2 HR = 0.90, 95% confidence interval (CI), 0.67-1.23; quartile 3 HR = 1.03, 95% CI, 0.76-1.38; quartile 4 (lowest) HR = 0.98, 95% CI, 0.72-1.33]. Sensitivity analyses yielded consistent results when accounting for race or time between diagnosis and blood draw. Moreover, we did not find evidence of interaction between 25(OH)D and clinical stage or BMI on OS. CONCLUSIONS: Serum level of 25(OH)D near time of diagnosis was not associated with OS in patients with esophageal adenocarcinoma. IMPACT: Screening 25(OH)D levels among patients with esophageal adenocarcinoma at diagnosis is not clinically relevant to their cancer prognosis based on present evidence.

BACKGROUND: Mediterranean diet (MD) adherence has been associated with reduced risks of esophageal and gastric cancer (subtypes) in a limited number of studies. We prospectively investigated associations between MD adherence and risks of esophageal squamous cell carcinoma (ESCC), esophageal adenocarcinoma (EAC), gastric cardia adenocarcinoma (GCA), and gastric non-cardia adenocarcinoma (GNCA) in a Dutch cohort. METHODS: Analyses were conducted using data from the 120852 participants of the Netherlands Cohort Study (NLCS), who were aged between 55 and 69 years at enrollment. Various MD scores, with and without alcohol, were calculated to estimate MD adherence. Using 20.3 years of follow-up, 133 ESCC, 200 EAC, 191 GCA, and 586 GNCA cases could be included in multivariable Cox regression analyses. RESULTS: Of the investigated scores, the alternate Mediterranean diet score without alcohol (aMEDr) performed best. aMEDr was inversely associated with risks of GCA and GNCA in men and women. However, statistical significance was only reached in men [ptrend: 0.019 (GCA), 0.016 (GNCA)]. Furthermore, higher aMEDr values were significantly associated with a reduced ESCC risk in men [HRper two-point increment (95% CI) = 0.57 (0.41-0.80), ptrend = 0.013], but not in women (pheterogeneity = 0.008). There was no evidence of an association between aMEDr and EAC risk. Educational level was a significant effect modifier for the association between aMEDr and GNCA risk (pheterogeneity = 0.0073). CONCLUSIONS: Higher MD adherence was associated with reduced risks of ESCC, GCA, and GNCA in the NLCS. However, the decreased ESCC risk might be limited to men.

OBJECTIVE: The assessment of prognostic nutritional index (PNI) before and during radiotherapy is an important parameter for the prognosis in patients with cancer. In this study, enteral tube feeding (ETF) was used during radiotherapy in patients with EC. Dynamic changes of various nutritional indicators (including PNI) were monitored. METHODS: Patients with EC who underwent radiotherapy between June 2016 and July 2017 were enrolled. ETF was performing with the energy of 25 kcal × kg/d. Nutritional status were evaluated. Least significant difference (LSD) was used for multiple comparisons between groups. RESULTS: A total of 148 patients were admitted, including 51 patients fed via ETF. For patients who were not scheduled to nutritional support, significant difference were observed in albumin (ALB) (P < 0.001), prealbimnin (PA) (P = 0.05) and PNI (P < 0.001) compared to levels before radiotherapy. In the patients fed via enteral tube, no significant difference were found in weight, BMI, ALB, retinol binding protein (RBP) and PA before and after radiotherapy, while PNI significantly decreased (P < 0.001). CONCLUSION: After preforming ETF with the energy of 25 kcal × kg/d in patients with EC during radiotherapy, PNI, the key nutritional index reflecting prognosis, significantly decreased.

Fermented dairy foods are known to be nutrient-rich and probiotic content, which gather optimism due to their potential in prevention and management of cancer. We searched the PubMed, Embase and CNKI databases for all available studies through July 2018 on the association between fermented dairy foods intake and cancer risk. The odds ratio (OR) corresponding to the 95% confidence interval (95% CI) was used to assess the association using a random-effect meta-analysis. Finally, 61 studies met the inclusion criteria for our study, with 1,962,774 participants and 38,358 cancer cases. Overall, statistical evidence of significantly decreased cancer risk was found to be associated with fermented dairy foods intake (OR = 0.86, 95% CI = 0.80-0.92) in cohort studies. Yogurt consumption was significantly with decreased cancer risk in the overall comparison (OR = 0.87, 95% CI = 0.80-0.95) and in the cohort studies (OR = 0.81, 95% CI = 0.74-0.88). In terms of subgroup analyses by cancer type, fermented dairy foods intake significantly decreased bladder cancer, colorectal cancer and esophageal cancer risk. In stratified analyses, significantly decreased colorectal cancer risk was found to be associated with cheese intake. Yogurt consumption was significantly decreased bladder cancer and colorectal cancer risk. Our meta-analysis indicated that fermented dairy foods intake was associated with an overall decrease in cancer risk.

OBJECTIVE: Preoperative nutritional status of patients is closely associated with their recovery after the surgery. This study aims to ascertain the impact exerted by the nutritional risk screening on clinical outcome of patients with esophageal cancer. METHODS: 160 patients with esophageal cancer aged over 60, having got therapy at the First Hospital of Jilin University from Jun 2016 to Feb 2017 were evaluated by adopting the NRS2002. 80 cases of patients got active therapy of nutritional support, and the other patients not supported nutritionally were selected as the control group. The comparison was drawn between two groups in serum albumin, serum immunoglobulin, postoperative complications, hospitalization, and hospitalization expenses. RESULTS: For all the patients, in 3 and 7 days after the surgery, the serum albumin in the nutritionally supported group outstripped that in group without nutritional support (P < 0.05) regardless of the nutritional risk. For the patients in the risk of nutrition, the IgA in the nutritionally supported group outstripped that of group without nutritional support (P < 0.05) in 3 and 7 days before the surgery, and the serum IgG outstripped that of the group without nutritional support in 1 and 3 days before the surgery (P < 0.05). In terms of the patients in the risk of nutrition, the average hospitalization of nutritionally supported group was shorter (P < 0.05), and the average hospitalization expenses were lower compared with those of the group without nutritional support. And for the patients in no risk, the hospitalization expenses of supported group surmounted those of group without nutritional support (P < 0.05), whereas the average hospitalization took on no statistic difference (P > 0.05). CONCLUSION: For the patients in the risk of nutrition, preoperative nutritional support can facilitate the nutritional status and immunization-relative result after surgery, which shall also decrease the average hospitalization and hospitalization cost.

Malnutrition develops in 79% patients with esophageal cancer. Thus, these patients represent a group of cancer patients, which is the most nutritionally compromised. Dysphagia and more than 10% loss of body weight are already present at the time of diagnosis. Treatments for esophageal cancer contribute significantly to the development of malnutrition. This paper describes the nutritional treatment of patients and nutritional strategies in patients with dysphagia and other nutritional problems that accompany the treatment of patients with esophageal cancer. Here are shown the types and methods of nutritional support, which are suitable for this group of patients. Nutritional support of patients with esophageal cancer is performed as a parallel therapeutic route.

Preoperative oral immunonutrition was demonstrated to improve immune response and to decrease the infection rate in patients with cancer. This study aimed to assess how immunonutrition could influence the immune cell response in the mucosal microenvironment of esophageal adenocarcinoma. Therefore, A prospective cohort of consecutive patients undergoing esophagectomy for esophageal adenocarcinoma was enrolled. A subgroup of them was given preoperative oral immunonutrition with Oral Impact® and was compared to those who received no preoperative supplementation. Mucosal samples from healthy esophagus were obtained at esophagectomy. Histology, immunohistochemistry, gene expression analysis, and cytofluorimetry were performed. Markers of activation of antigen-presenting cells (CD80, CD86, and HLA-I), innate immunity (TLR4 and MyD88), and cytotoxic lymphocyte infiltration and activation (CD8, CD38, CD69, and CD107) were measured. In all, 50 patients received preoperative Oral Impact® and 129 patients received no nutritional support. CD80, CD86, MyD88, and CD69 messenger RNA expression was significantly increased in patients receiving immunonutrition compared to controls. In the subgroup of patients with stages I-II cancer, the rate of epithelial cells expressing CD80 and HLA-ABC was significantly higher in those receiving immunonutrition compared to controls as well as CD8+ CD28+ cell rate. Immunonutrition administration before surgery was significantly associated to increased degranulating CD8 and natural killer cells (CD107+) infiltrating the healthy esophageal mucosa. All the comparisons were adjusted for cancer stage and preoperative therapy. In conclusion, in healthy esophageal mucosa of patients undergoing esophagectomy, a 5-day course of immunonutrition enhances expression of antigen-presenting cells activity and increased CD8+ T cell activation and degranulating activity. Further studies are warranted to understand the clinical implication in terms of cancer recurrence.

PURPOSE OF REVIEW: Esophageal diseases represent a wide variety of conditions affecting esophageal anatomy, physiology, and motility. Therapy focuses on pharmacotherapy and endoscopic or surgical management. Dietary therapy can be considered in management algorithms for specific esophageal diseases. This review focuses on outlining the literature related to dietary therapy in gastroesophageal reflux disease, eosinophilic esophagitis, Barrett's esophagus, and esophageal adenocarcinoma. RECENT FINDINGS: Currently, data are strongest for dietary manipulation in eosinophilic esophagitis, specifically the six-food elimination diet. Dietary effects on gastroesophageal reflux disease are less clear, though newer research indicates that increased fiber with reduction in simple sugar intake may improve symptoms. In terms of Barrett's esophagus and esophageal adenocarcinoma, antioxidant intake may affect carcinogenesis, though to an unknown degree. Outcomes data regarding dietary manipulation for the management of esophageal diseases is heterogeneous. Given the rising interest in non-pharmacological treatment options for these patients, continued research is warranted.

PURPOSE: The aim of this pilot study was to investigate the effects of a preoperative immune-modulating diet (IMD) before thoracoscopic esophagectomy for patients with esophageal cancer. METHODS: Thirty patients who were diagnosed with resectable esophageal cancer were assigned to two groups: the IMD (n = 15) and the standard liquid diet (SLD; n = 15) groups. We evaluated postoperative parameters, such as the incidence of complications and the postoperative levels of cytokines as the primary endpoints. The secondary endpoint was the length of hospital stay. RESULTS: The peak levels of interleukin (IL)-6 and tumor necrosis factor (TNF)-α appeared on postoperative day (POD) 1 and POD 2 in the IMD and SLD group, respectively. The peak level of C-reactive protein (CRP) appeared on POD 3 in both groups (IMD 9.9 mg/dL, SLD 15.2 mg/dL). Overall, TNF-α levels in the IMD group were lower than those in the SLD group (P = 0.033). Furthermore, IL-6 (P = 0.182) and CRP (P = 0.191) levels, and the incidence of postoperative pneumonia (7.1 vs. 26.7%; P = 0.330) tended to be lower in the IMD group than in the SLD group. CONCLUSIONS: Preoperative IMD suppressed the elevation of the TNF-α levels after thoracoscopic esophagectomy in patients with esophageal cancer, although no different tendency was detected in terms of IL-6, CRP or postoperative complications.

Aberrant methylation of DNA is a common event in the development of cancers, including squamous cell carcinoma (SCC) of the human esophagus. In the present study, we determined: (a) whether aberrant DNA methylation also occurs in the development of N-nitrosomethylbenzylamine (NMBA)-induced tumorigenesis in the rat esophagus, a model of human esophageal SCC; and (b) if so, whether dietary black raspberries (BRBs) are capable of preventing this aberrant DNA methylation. A diet containing 5% BRBs inhibited the development of NMBA-induced tumors in the rat esophagus. This inhibition was associated with reduced mRNA levels of the DNA methyltransferases, Dnmt1 and Dnmt3b, in both dysplastic lesions and in papillomas of the esophagus. In addition, promoter methylation of Sfrp4, a WNT pathway antagonist, was significantly reduced by the berry diet, and this was associated with decreased nuclear localization of ß-CATENIN and reduced expression of c-MYC protein in NMBA-treated esophagi. Decreased promoter methylation of Sfrp4 correlated with decreased expression of Dmnt3b and, ultimately, with increased Sfrp4 mRNA expression. This suggests that epigenetic alterations in NMBA-induced rat esophageal tumorigenesis recapitulate epigenetic events in human esophageal SCC, and that BRBs could be useful in preventing the aberrant DNA methylation involved in the development of human esophageal SCC. © 2015 Wiley Periodicals, Inc.

Esophageal carcinomas often have a poor prognosis due to early lymph node metastasis. Epithelial-mesenchymal transition (EMT) is strongly associated with the acquisition of cancer metastasis and invasion. However, there is no established treatment to eliminate the EMT of cancer cells. Iron is an essential element for both normal and cancer cells in humans. Recently, iron depletion has been discovered to suppress tumor growth. Therefore, we hypothesized that decreased iron conditions would regulate EMT phenotypes, as well as suppressing tumor growth. The human TE esophageal cancer cell lines and OE19 were used in our study. Decreased iron conditions were made using an iron-depletion diet in mice and the iron chelator deferasirox for cell studies. Migration and invasion abilities of cells were measured using migration, invasion, and sphere-formation assays. Esophageal subcutaneous tumor growth was suppressed in decreased iron conditions. In vitro study showed that decreased iron conditions inhibited esophageal cancer cell proliferation as well as migration and invasion abilities, with downregulation of N-cadherin expression. Also, migration and invasion abilities were suppressed by inhibiting expression of N-cadherin. In conclusion, decreased iron conditions revealed a profound anticancer effect by the suppression of tumor growth and the inhibition of migration and invasion abilities via N-cadherin.

BACKGROUND: The goal of this work was to identify barriers and enablers to the implementation of nutrition care in head and neck and esophageal (HNE) cancers and to prioritize barriers to help improve the nutrition care process. MATERIALS AND METHODS: This study used a multimethod qualitative study design (including semistructured interviews, focus group). Interviews (n = 29) were conducted at 5 European sites providing care and treatment to patients with HNE cancers. A focus group (n = 21) reviewed and corroborated interview findings and identified priorities for nutrition care. Participants were healthcare providers and researchers with direct experience in the field of HNE cancer. RESULTS: Five themes with accompanying barriers and enablers were identified related to nutrition care: (1) evidence for the benefit of nutrition interventions, (2) implementation of nutrition care processes (assessment, intervention, and follow-up), (3) characteristics of healthcare providers, (4) site factors, and (5) patient characteristics. Focus group discussions identified 2 priorities that must be acted on to improve nutrition care: (1) improve the evidence base and (2) develop standardized nutrition care pathways. CONCLUSION: Themes related to nutrition care in HNE cancers were similar between sites, but barriers and enablers differed. Interview and focus group participants agreed the following actions will result in improvements in nutrition care: (1) enhance the evidence base to test the benefit of nutrition interventions, with a focus on resolving specific controversies regarding nutrition therapy, and (2) establish a minimum data set with a goal to create standardized nutrition care pathways where roles and responsibilities for care are clearly defined.
