We also aimed to investigate ALDH2 genotypic distributions between subjects from high- and low-incidence areas for both GCA and esophageal squamous cell carcinoma(ESCC).Methods: We designed a case-control study including 2,686 patients with GCA and 3,675 control subjects from high- and lowincidence areas for both GCA and ESCC in China. Taq Man allele discrimination assay was used to genotype the rs671 polymorphism. χ~2 test and binary logistic regression analysis were used to estimate the odds ratios for the development of GCA,and multivariate ordinal logistic regression was used to analyze ALDH2 genotypic distributions among different groups.Results: Compared with ALDH2*1/*1 homozygotes, ALDH2*1/*2 and ALDH2*2/*2 carriers did not increase the risk for GCA in the Chinese Han population(P>0.05). Interestingly, the ratio of homozygous or heterozygous ALDH2 *2 carriers in highincidence areas for both GCA and ESCC was lower than that in low-incidence areas(P<0.001).Conclusions: Genotypes of rs671 at ALDH2 may not increase GCA susceptibility in Chinese Han populations. In addition, the ALDH2 genotypic distribution differs between Chinese Han populations from high- and low-incidence areas for both GCA and ESCC. Our findings may shed light on the possible genetic mechanism for the dramatic geographic differences of GCA occurrence in China.展开更多

Our objective was to determine the relationship between pathological characteristics, treatment protocols, and survival outcomes in Chinese CEC patients.Methods: A total of 500 Chinese CEC patients were selected from our 500,000 esophageal and gastric cardia carcinoma database(1973–2018). There were two main groups: patients treated with surgery, and patients receiving non-surgical treatments(radiotherapy, radiochemotherapy, and chemotherapy). The Chi-square test and Kaplan–Meier method were used to compare the continuous variables and survival.Results: Among the 500 CEC patients, 278(55.6%) were male, and the median age was 60.9 ± 9.4 years. A total of 496 patients(99.2%) were diagnosed with squamous cell carcinoma. In 171(34.2%) patients who received surgery, 22(12.9%) had undergone laryngectomy. In 322(64.4%) patients who received non-surgical treatments, 245(76.1%) received radiotherapy. Stratified survival analysis showed that only T stage was related with survival outcomes for CEC patients in the surgical group, and the outcomes between laryngectomy and non-laryngectomy patients were similar. It was noteworthy that the 5-year survival rate was similar in CEC patients among the different groups treated with surgery, radiotherapy, chemotherapy, or radiochemotherapy(P = 0.244). Conclusions: The CEC patients had similar survival outcomes after curative esophagectomy and radiotherapy, including those with or without total laryngectomy. These findings suggest that radiotherapy could be the initial choice for treatment of Chinese CEC patients.展开更多

Univariate analyses showed that disclosure of confirmed ESCC diagnosis to patients was correlated with gender, family history of cancer(FHC), education level, vocation, hospital administrative level, and attitudes of family members(P < 0.05). Furthermore,multivariate analysis indicated that attitude of family members was the most important and an independent factor for diagnosis disclosure. Those patients with a negative FHC, under-education, manual occupation, advanced stages, and hospitalized in municipal hospitals exhibited a low rate of truth telling.Conclusions: Truth telling for ESCC patients in Henan is not prevalent and may be improved through consultation with family members, particularly for patients with a negative FHC, poor education, manual occupation, and advanced stages.展开更多

文摘BACKGROUND The combination of programmed cell death protein-1(PD-1)inhibitor and che-motherapy is approved as a standard first-or second-line treatment in patients with advanced oesophageal or gastric cancer.However,it is unclear whether this combination is superior to chemotherapy alone.AIM To assess the comparative effectiveness and tolerability of combining PD-1 inhibitors with chemotherapy vs chemotherapy alone in patients with advanced gastric cancer,gastroesophageal junction(GEJ)cancer,or oesophageal carcinoma.METHODS We searched the PubMed and Embase databases for studies that compared the efficacy and tolerance of PD-1 inhibitors in combination with chemotherapy vs chemotherapy alone in patients with advanced oesophageal or gastric cancer.We employed either random or fixed models to analyze the outcomes of each clinical trial,en-compassing data on overall survival(OS),progression-free survival(PFS),objective response rate,and adverse events(AEs).RESULTS Nine phase 3 clinical trials(7016 advanced oesophageal and gastric cancer patients)met the inclusion criteria.Our meta-analysis demonstrated that the pooled PD-1 inhibitor+chemotherapy group had a significantly longer OS than the chemotherapy-alone group[hazard ratio(HR)=0.76,95%confidence interval(CI):0.71-0.81];the pooled PFS result was consistent with that of OS(HR=0.67,95%CI:0.61-0.74).The count of patients achieving an objective response in the PD-1 inhibitor+chemotherapy group surpassed that of the chemotherapy-alone group[odds ratio(OR)=1.86,95%CI:1.59-2.18].AE incidence was also higher in the combination-therapy group than in the chemotherapy-alone group,regardless of whether≥grade 3 only(OR=1.30,95%CI:1.07-1.57)or all AE grades(OR=1.88,95%CI:1.39-2.54)were examined.We performed a subgroup analysis based on the programmed death-ligand 1(PD-L1)combined positive score(CPS)and noted extended OS and PFS durations within the CPS≥1,CPS≥5,and CPS≥10 subgroups of the PD-1 inhibitor+chemotherapy group.CONCLUSION In contrast to chemotherapy alone,the combination of PD-1 inhibitor and chemotherapy appears to present a more favorable option for initial or subsequent treatment in patients with gastric cancer,GEJ tumor,or oesophageal cancer.This holds true particularly for individuals with PD-L1 CPS scores of≥5 and≥10.

文摘BACKGROUND Gastric cardia adenocarcinoma(GCA),which has been classified as type II adenocarcinoma of the esophagogastric junction in western countries,is of similar geographic distribution with esophageal squamous cell carcinoma in China,and even referred as"sister cancer"by Chinese oncologists.The molecular mechanism for GCA is largely unknown.Recent studies have shown that decreased expression of E-cadherin is associated with the invasion and metastasis of multiple cancers.However,the E-cadherin expression has not been well characterized in gastric cardia carcinogenesis and its effect on GCA prognosis.AIM To characterize E-cadherin expression in normal gastric cardia mucosa,dysplasia and GCA tissues,and its influence on prognosis for GCA.METHODS A total of 4561 patients with GCA were enrolled from our previously established GCA and esophageal cancer databases.The enrollment criteria included radical surgery for GCA,but without any radio-or chemo-therapy before operation.The GCA tissue from 4561 patients and matched adjacent normal epithelial tissue(n=208)and dysplasia lesions(n=156)were collected,and processed as tissue microarray for immunohistochemistry.The clinicopathological characteristics were retrieved from the medical records in hospital and follow-up was carried out through letter,telephone or home interview.E-cadherin protein expression was determined by two step immunohistochemistry.Kaplan–Meier and Cox regression analyses were used to correlate E-cadherin protein expression with survival of GCA patients.RESULTS Of the 4561 GCA patients,there were 3607 males with a mean age of 61.6±8.8 and 954 females with a mean age of 61.9±8.6 years,respectively.With the lesions progressed from normal gastric cardia mucosa to dysplasia and GCA,the positive immunostaining rates for E-cadherin decreased significantly from 100%to 93.0%and 84.1%,respectively(R2=0.9948).Furthermore,E-cadherin positive immunostaining rate was significantly higher in patients at early stage(0 and I)than in those at late stage(II and III)(92.7%vs 83.7%,P=0.001).E-cadherin positive expression rate was significantly associated with degree of differentiation(P=0.001)and invasion depth(P<0.001).Multivariate analysis showed that the GCA patients with positive E-cadherin immunostaining had better survival than those with negative(P=0.026).It was noteworthy that E-cadherin positive expression rate was similar in patients with positive and negative lymph node metastasis.However,in patients with negative lymph node metastasis,those with positive expression of E-cadherin had better survival than those with negative expression(P=0.036).Similarly,in patients with late stage GCA,those with positive expression of E-cadherin had better survival than those with negative expression(P=0.011).CONCLUSION E-cadherin expression may be involved in gastric cardia carcinogenesis and low expression of E-cadherin may be a promising early biomarker and overall survival predictor for GCA.

文摘Objective: There are no comprehensive studies on survival outcomes and optimal treatment protocols for cervical esophageal cancer(CEC), due to its rare clinical prevalence. Our objective was to determine the relationship between pathological characteristics, treatment protocols, and survival outcomes in Chinese CEC patients.Methods: A total of 500 Chinese CEC patients were selected from our 500,000 esophageal and gastric cardia carcinoma database(1973–2018). There were two main groups: patients treated with surgery, and patients receiving non-surgical treatments(radiotherapy, radiochemotherapy, and chemotherapy). The Chi-square test and Kaplan–Meier method were used to compare the continuous variables and survival.Results: Among the 500 CEC patients, 278(55.6%) were male, and the median age was 60.9 ± 9.4 years. A total of 496 patients(99.2%) were diagnosed with squamous cell carcinoma. In 171(34.2%) patients who received surgery, 22(12.9%) had undergone laryngectomy. In 322(64.4%) patients who received non-surgical treatments, 245(76.1%) received radiotherapy. Stratified survival analysis showed that only T stage was related with survival outcomes for CEC patients in the surgical group, and the outcomes between laryngectomy and non-laryngectomy patients were similar. It was noteworthy that the 5-year survival rate was similar in CEC patients among the different groups treated with surgery, radiotherapy, chemotherapy, or radiochemotherapy(P = 0.244). Conclusions: The CEC patients had similar survival outcomes after curative esophagectomy and radiotherapy, including those with or without total laryngectomy. These findings suggest that radiotherapy could be the initial choice for treatment of Chinese CEC patients.

文摘BACKGROUND Preoperative pulmonary function plays an important role in selecting surgical candidates and assessing postoperative complications.Reduced pulmonary function is associated with poor survival in several cancers,but the prognostic value of preoperative pulmonary function in esophageal squamous cell carcinoma(ESCC)is unclear.Nutritional and systemic inflammation parameters are vital to cancer survival,and the combination of these parameters improves the prognostic value.The hemoglobin,albumin,lymphocytes and platelets(HALP)score is a novel prognostic indicator to reflect the nutritional and inflammation status,but the clinical effects of the HALP score combined with maximal voluntary ventilation(MVV),an important parameter of pulmonary function,have not been well studied in ESCC.AIM To investigate the prognostic value of MVV and HALP score for assessing postoperative survival of ESCC patients.METHODS Data form 834 ESCC patients who underwent radical esophagectomy with R0 resection were collected and retrospectively analyzed.Preoperative MVV and HALP data were retrieved from medical archives.The HALP score was calculated by the formula:Hemoglobin(g/L)×albumin(g/L)×lymphocytes(/L)/platelets(/L).The optimal cut-off values of MVV and HALP score were calculated by the receiver operating characteristic curve analysis.The Kaplan-Meier method with log-rank test was used to draw the survival curves for the variables tested.Multivariate Cox proportional hazard regression models were used to analyze the independent prognostic factors for overall survival.RESULTS MVV was significantly associated with gender(P<0.001),age at diagnosis(P<0.001),smoking history(P<0.001),drinking history(P<0.001),tumor length(P=0.013),tumor location(P=0.037)and treatment type(P=0.001).The HALP score was notably associated with gender(P<0.001),age at diagnosis(P=0.035),tumor length(P<0.001)and invasion depth(P=0.001).Univariate Cox regression analysis showed that low MVV and low HALP score were associated with worse overall survival(all P<0.001).Multivariate analysis showed that low MVV and the HALP score were both independent risk factors for overall survival(all P<0.001).The combination of MVV and HALP score improved the prediction performance for overall survival than tumor-node-metastasis.Also,low combination of MVV and HALP score was an independent risk factor for poor overall survival(P<0.001).CONCLUSION MVV,HALP score and their combination are simple and promising clinical markers to predict overall survival of ESCC patients.

文摘Objective: This study aims to investigate the truth-telling status and the relevant factors of esophageal squamous cell carcinoma(ESCC) patients in Henan, China.Methods: A cross-sectional study from April to June 2015 using questionnaires was given to 301 family members of hospitalized ESCC patients based in three affiliated hospitals of Zhengzhou University(i.e., The First Hospital, The Second Hospital, and Tumor Hospital) and Anyang Tumor Hospital.Results: Among the 41.9%(126/301) hospitalized ESCC patients who knew of their true diagnoses, only 4.0% patients were informed by their corresponding responsible doctors, 39.7% by their family members, and 56.3% by themselves. Univariate analyses showed that disclosure of confirmed ESCC diagnosis to patients was correlated with gender, family history of cancer(FHC), education level, vocation, hospital administrative level, and attitudes of family members(P < 0.05). Furthermore,multivariate analysis indicated that attitude of family members was the most important and an independent factor for diagnosis disclosure. Those patients with a negative FHC, under-education, manual occupation, advanced stages, and hospitalized in municipal hospitals exhibited a low rate of truth telling.Conclusions: Truth telling for ESCC patients in Henan is not prevalent and may be improved through consultation with family members, particularly for patients with a negative FHC, poor education, manual occupation, and advanced stages.

文摘BACKGROUND Primary small cell carcinoma of the esophagus(PSCE)is a highly invasive malignant tumor with a poor prognosis compared with esophageal squamous cell carcinoma.Due to the limited samples size and the short follow-up time,there are few reports on elucidating the prognosis of PSCE,especially on the establishment and validation of a survival prediction nomogram model covering general information,pathological factors and specific biological proteins of PSCE patients.AIM To establish an effective nomogram to predict the overall survival(OS)probability for PSCE patients in China.METHODS The nomogram was based on a retrospective study of 256 PSCE patients.Univariate analysis and multivariate Cox proportional hazards regression analysis were used to examine the prognostic factors associated with PSCE,and establish the model for predicting 1-,3-,and 5-year OS based on the Akaike information criterion.Discrimination and validation were assessed by the concordance index(C-index)and calibration curve and decision curve analysis(DCA).Histology type,age,tumor invasion depth,lymph node invasion,detectable metastasis,chromogranin A,and neuronal cell adhesion molecule 56 were integrated into the model.RESULTS The C-index was prognostically superior to the 7th tumor node metastasis(TNM)staging in the primary cohort[0.659(95%CI:0.607-0.712)vs 0.591(95%CI:0.517-0.666),P=0.033]and in the validation cohort[0.700(95%CI:0.622-0.778)vs 0.605(95%CI:0.490-0.721),P=0.041].Good calibration curves were observed for the prediction probabilities of 1-,3-,and 5-year OS in both cohorts.DCA analysis showed that our nomogram model had a higher overall net benefit compared to the 7th TNM staging.CONCLUSION Our nomogram can be used to predict the survival probability of PSCE patients,which can help clinicians to make individualized survival predictions.

文摘A novel computational system was used to decipher the targets and mechanisms of Chrysanthemum morifolium against hepatocellular carcinoma.The putative target profile of Chrysanthemum morifolium against hepatocellular carcinoma was identified from Traditional Chinese Medicine Systems Pharmacology and DrugBank.Next,identification of the protein-protein interaction network of Chrysanthemum morifolium against hepatocellular carcinoma targets,and the identification of differentially expressed genes in hepatocellular carcinoma,relied on data from the NCBI database.Finally,Kyoto Encyclopedia of Genes and Genomes and Gene Ontology were used to analyze the common targets.Forty-eight active compounds in Chrysanthemum morifolium were identified by Traditional Chinese Medicine Systems Pharmacology and DrugBank,and 71 differentially expressed genes were identified in the GEO database.Further,10 core target proteins were selected,including CYP1A1,ADRB2,ADRA1B,PGR,MAOB,SLC6A4,GABRA1,MAOA,NOS3 and PTGS2.These target genes were also found to be associated with pathways involved in adrenergic receptor activity and catecholamine binding.
文摘Objective:To investigate the value of spleen and pancreatic tail thorax translocation on the residual stomach esophagus anastomosis.Methods:10 patients with esophageal carcinoma after gastrectomy were enrolled in this study. Lesions were removed through left thoracotomy and residual stomach was fully mobilized,with short gastric artery being re- served.Spleen and pancreatic tail were dissected from the back of peritoneum and transposed into thorax.Residual stomach esophagus anastomosis was performed.Results:All the operation went favorably.Patients were recovered rapidly and a relatively good prognosis was acquired.Late leakage and pleural effusion happened in one case respectively,but these com- plications were cured through conservative management without operation death.Conclusion:Residual stomach is an ideal candidate for the replacement of esophagus and residual stomach esophagus anastomosis is a simple operative alternative with few trauma and good results for the treatment of esophageal carcinoma after gastrectomy.
文摘A 58 years old male patient underwent esophagectomy for esophageal cancer.Refractory chylothorax happened after operation in spite of different treatment including conservation therapy and thoracic duct ligation.He was enterally administrated 250 mL 30% intralipid before operation.Exploration showed there was a milky leakage from the soft tissue near the anastomotic stoma behind aortic arch where is difficult to handle.We gently mobilized the aorta in the front of the ninth spine and bundled it with its adjacent tissue including azygos vein and thoracic duct with a dacron patch.The leakage ceased rightly and the following recovery went smoothly.
