The incidence and mortality rates of esophagus cancer were calculated by area(urban/rural), region(eastern, middle, western), gender and age group(0, 1-4, 5-84 by 5 years and 85+ years). China census in 2000 and Segi’s world population were applied for age-standardized rates. Joinpoint model was used for time-trend analysis.Results: The crude incidence rate of esophagus cancer was 22.57/100,000. The age-standardized incidence rates by China standard population(ASIRC) and by world standard population(ASIRW) were 14.58/100,000 and14.80/100,000, respectively. The crude mortality rate of esophagus cancer was 17.19/100,000. The agestandardized mortality rates by Chinese standard population(ASMRC) and by world standard population(ASMRW) were 10.80/100,000 and 10.86/100,000 respectively. Incidence and mortality rates of esophagus cancer were higher in males than in females and higher in rural areas than in urban areas. The crude incidence rate in middle areas was the highest among all areas, followed by western areas and eastern areas. The age-specific incidence rate of esophagus cancer was relatively low in age groups before 40 years old and then increased after 45 years old. It peaked in the age group of 80-84 years. The patterns of age-specific mortality rates of esophagus cancer were close to those of age-specific incidence rates. The ASIRC of esophagus cancer decreased dramatically by 29.87% between 2003 and 2012, from 14.33/100,000 to 10.05/100,000. The esophagus cancer incidence rate decreased by 3.76% per year(P>0.05). The mortality rate of esophagus cancer decreased annually over the decades from 2003 to 2012 in China(P>0.05). In females, the annual percentage change(APC) of mortality rate was-5.43%[95% confidence intervals(95% CI):-6.50%,-4.30%](P<0.05) and the mortality rate of esophagus cancer in rural females was statistically significant(APC:-3.20%, 95% CI:-4.20%,-2.20%)(P<0.05).Conclusions: The focus of prevention and treatment for esophagus cancer is strengthening primary prevention of esophageal cancer, and promoting esophagus cancer secondary prevention to reduce incidence and mortality rates of esophagus cancer, prolong survival rate of patients and decline the burden of esophagus cancer in China.展开更多

Meth...Objective: To observe the clinical therapeutic effects of Rehmannia Oral Liquid on the syndrome of heat accumulation with Yin consumption in intermediate or late esophagus cancer patients undergoing radiotherapy. Methods: The IFN-α, TNF-α, IL-1β and TGF-β1 levels in sera were determined by the method of ABC-WLISA before and after the treatment with Rehmannia Oral Liquid. At the same time, the observation was carried out on the patient's general condition, symptoms and signs, barium meal or CT examinations, and biopsy. Another 30 cases of esophagus cancer were treated singly with radiotherapy as the control group. Results: Rehmannia Oral Liquid could obviously improve the patient's general condition, and the symptoms and signs after radiotherapy. Based on the X-ray examination and biopsy, the short-term local control rate of the treatment group and the control group was 70.0% and 40.0% respectively, showing a significant difference (P<0.05). Before the treatment, the level of serum IFN-α of both cancer groups was lower and the levels of TNF-α, IL-1β and TGF-β1 were higher than that of normal group. After treatment, the level of IFN-α in both treatment group and control group increased significantly (P<0.01), and the treatment group improved more obviously than the control group (P<0.05). The level of TNF-α of both groups decreased significantly (P<0.01) after treatment, and the level of IL-1β decreased in treatment group and increased in control group without the significant difference as compared with that before treatment. The level of TGF-β1 was significantly increased in control group (P<0.05) and decreased in treatment group (P>0.05) after treatment. The difference between groups was significant (P<0.05). Conclusion: Rehmannia Oral Liquid can obviously reduce the radiotherapy reaction, improve the quality of life, and raise the therapeutic effects. The action mechanism of the Liquid may lie in balancing the cytokine network and regulating the disordered signal transmission.展开更多

He had undergone esophagectomy for esophageal cancer(T3N2M0 Stage Ⅲ) 11 years earlier. Endoscopic examination revealed an anastomotic stricture; signs of inflammation,including redness,erosion,edema,bleeding,friability,and exudate with white plaques; and multiple depressions in the residual esophagus. Radiographical examination revealed numerous fine,gastrografinfilled projections and an anastomotic stricture. Biopsy specimens from the area of the anastomotic stricture revealed inflammatory changes without signs of malignancy. Candida glabrata was detected with a culture test of the biopsy specimens. The stricture was diagnosed as a benign stricture that was caused by esophageal intramural pseudodiverticulosis. Accordingly,endoscopic balloon dilatation was performed and antifungal therapy was started in the hospital. Seven weeks later,endoscopic examination revealed improvement in the mucosal inflammation; only the pseudodiverticulosis remained. Consequently,the patient was discharged. At the latest follow-up,the patient was symptomfree and the pseudodiverticulosis remained in the residual esophagus without any signs of stricture or inflammation.展开更多

METHODS A cohort study within a single tertiary center included 386 consecutive patients with biopsy proven BE, who were recruited between 2004-2014. Endoscopic and histologic data were prospectively recorded. Cancer morbidity was obtained from the national cancer registry. Main outcomes were BE related(defined as esophagus and cardia) and non-BE related cancers(all other cancers). Cancer incidence and all-causemortality were compared between patients with highgrade dysplasia(HGD) and with low-grade or no dysplasia(non-HGD) using Kaplan-Meier curves and cox regression models.RESULTS Of the 386 patients, 12 had HGD, 7 had a BE related cancer. There were 75(19.4%) patients with 86 cases of lifetime cancers, 76 of these cases were non-BE cancers. Seven(1.8%) and 18(4.7%) patients had BE and non-BE incident cancers, respectively. Twelve(3.1%) patients had HGD as worst histologic result. Two(16.7%) and 16(4.4%) incident non-BE cancers occurred in the HGD and non-HGD group, respectively. Ten-year any cancer and non-BE cancer free survival was 63% and 82% in the HGD group compared to 93% and 95% at the non-HGD group, respectively. Log-rank test for patients with more than one endoscopy, assuring longer follow up, showed a significant difference(P < 0.001 and P = 0.017 respectively). All-cause mortality was not significantly associated with BE HGD.CONCLUSION Patients with BE and HGD, may have a higher risk for all-cause cancer morbidity. The implications on cancer prevention recommendations should be further studied.展开更多

At first, conventional endoscopy showed a reddish and depressed lesion in the stomach and an elevated lesion in the posterior wall of the hypopharynx. An endoscopic biopsy showed adenocarcinoma in the stomach, and squamous cell carcinoma in the hypopharynx. On the further examination, trans-nasal endoscopy with narrow band imaging (NBI) was performed. During the trumpet maneuver, a huge protruded lesion was observed and it reached to the orifice of the esophagus. Other superficial lesion located at left pyriform sinus was detected by NBI system as brownish area with brown dots. Furthermore, superficial esophageal cancer in the cervical esophagus was detected. Finally, 4 carcinomas in upper gastrointestinal tract were detected. Among them, the hypopharyngeal cancer was the most advanced (T3N0). The patient hoped to preserve his voice and swallowing function, endoscopic laryngo-pharyngeal surgery (ELPS) was performed for the hypopharyngeal cancer. Endoscopic mucosal resection (EMR) was performed for the esophageal cancer, and Endoscopic submucosal dissection (ESD) was performed for the gastric cancer. Under collaboration between a head and neck surgeon and an endoscopist, the tumor was resected en-bloc. The histopathological findings of hypopharyngeal cancer were squamous cell carcinoma, subeipthelial invasion, 29 × 28 × 4.2 mm. The others were diagnosed as mucosal cancers. The patient is currently alive with no recurrence at 28 months after the surgery;there is no stricture at the cervical esophagus. Endoscopic laryngopharyngeal surgery for the tumor of pharyngo-esophageal junction can provide a less invasive treatment.展开更多

文摘Accurate preoperative prediction of lymph node metastasis(LNM)in esophageal cancer(EC)patients is of crucial clinical significance for treatment planning and prognosis.AIM To develop a clinical radiomics nomogram that can predict the preoperative lymph node(LN)status in EC patients.METHODS A total of 32 EC patients confirmed by clinical pathology(who underwent surgical treatment)were included.Real-time fluorescent quantitative reverse transcription-polymerase chain reaction was used to detect the expression of B7-H3 mRNA in EC tissue obtained during preoperative gastroscopy,and its correlation with LNM was analyzed.Radiomics features were extracted from multi-modal magnetic resonance imaging of EC using Pyradiomics in Python.Feature extraction,data dimensionality reduction,and feature selection were performed using XGBoost model and leave-one-out cross-validation.Multivariable logistic regression analysis was used to establish the prediction model,which included radiomics features,LN status from computed tomography(CT)reports,and B7-H3 mRNA expression,represented by a radiomics nomogram.Receiver operating characteristic area under the curve(AUC)and decision curve analysis(DCA)were used to evaluate the predictive performance and clinical application value of the model.RESULTS The relative expression of B7-H3 mRNA in EC patients with LNM was higher than in those without metastasis,and the difference was statistically significant(P<0.05).The AUC value in the receiver operating characteristic(ROC)curve was 0.718(95%CI:0.528-0.907),with a sensitivity of 0.733 and specificity of 0.706,indicating good diagnostic performance.The individualized clinical prediction nomogram included radiomics features,LN status from CT reports,and B7-H3 mRNA expression.The ROC curve demonstrated good diagnostic value,with an AUC value of 0.765(95%CI:0.598-0.931),sensitivity of 0.800,and specificity of 0.706.DCA indicated the practical value of the radiomics nomogram in clinical practice.CONCLUSION This study developed a radiomics nomogram that includes radiomics features,LN status from CT reports,and B7-H3 mRNA expression,enabling convenient preoperative individualized prediction of LNM in EC patients.
文摘This editorial explores the potential integration of non-Western medicine into radiotherapy for cervical cancer.While radiotherapy remains a radical treatment for cervical cancer,its associated toxicity and decline in quality of life can significantly impact patients’lives.Currently,most treatments are supportive,with no specific treatment options available in Western medicine.Non-Western medicine,often less toxic and easier to administer,has shown promising results when used alongside radiotherapy for cervical cancer.Despite these potential benefits,challenges such as limited evidence and restricted application areas persist.While non-Western medicines may offer potential improvements in chemoradiotherapy outcomes for cervical cancer,further research is necessary to substantiate these benefits.

文摘BACKGROUND Mitochondrial genes are involved in tumor metabolism in ovarian cancer(OC)and affect immune cell infiltration and treatment responses.AIM To predict prognosis and immunotherapy response in patients diagnosed with OC using mitochondrial genes and neural networks.METHODS Prognosis,immunotherapy efficacy,and next-generation sequencing data of patients with OC were downloaded from The Cancer Genome Atlas and Gene Expression Omnibus.Mitochondrial genes were sourced from the MitoCarta3.0 database.The discovery cohort for model construction was created from 70% of the patients,whereas the remaining 30% constituted the validation cohort.Using the expression of mitochondrial genes as the predictor variable and based on neural network algorithm,the overall survival time and immunotherapy efficacy(complete or partial response)of patients were predicted.RESULTS In total,375 patients with OC were included to construct the prognostic model,and 26 patients were included to construct the immune efficacy model.The average area under the receiver operating characteristic curve of the prognostic model was 0.7268[95% confidence interval(CI):0.7258-0.7278]in the discovery cohort and 0.6475(95%CI:0.6466-0.6484)in the validation cohort.The average area under the receiver operating characteristic curve of the immunotherapy efficacy model was 0.9444(95%CI:0.8333-1.0000)in the discovery cohort and 0.9167(95%CI:0.6667-1.0000)in the validation cohort.CONCLUSION The application of mitochondrial genes and neural networks has the potential to predict prognosis and immunotherapy response in patients with OC,providing valuable insights into personalized treatment strategies.
文摘BACKGROUND Barrett's esophagus(BE)is a known premalignant precursor to esophageal adenocarcinoma(EAC).The prevalence rates continue to rise in the United States,but many patients who are at risk of EAC are not screened.Current practice guidelines include male gender as a predisposing factor for BE and EAC.The population-based clinical evidence regarding female gender remains limited.AIM To study comparative trends of gender disparities in patients with BE in the United States.METHODS A nationwide retrospective study was conducted using the 2009-2019 National Inpatient Sample(NIS)database.Patients with a primary or secondary diagnosis code of BE were identified.The major outcome of interest was determining the gender disparities in patients with BE.Trend analysis for respective outcomes for females was also reported to ascertain any time-based shifts.RESULTS We identified 1204190 patients with BE for the study period.Among the included patients,717439(59.6%)were men and 486751(40.4%)were women.The mean age was higher in women than in men(67.1±0.4 vs 66.6±0.3 years,P<0.001).The rate of BE per 100000 total NIS hospitalizations for males increased from 144.6 in 2009 to 213.4 in 2019(P<0.001).The rate for females increased from 96.8 in 2009 to 148.7 in 2019(P<0.001).There was a higher frequency of obesity among women compared to men(17.4%vs 12.6%,P<0.001).Obesity prevalence among females increased from 12.3%in 2009 to 21.9%in 2019(P<0.001).A lower prevalence of smoking was noted in women than in men(20.8%vs 35.7%,P<0.001).However,trend analysis showed an increasing prevalence of smoking among women,from 12.9%in 2009 to 30.7%in 2019(P<0.001).Additionally,there was a lower prevalence of alcohol abuse,Helicobacter pylori(H.pylori),and diabetes mellitus among females than males(P<0.001).Trend analysis showed an increasing prevalence of alcohol use disorder and a decreasing prevalence of H.pylori and diabetes mellitus among women(P<0.001).CONCLUSION The prevalence of BE among women has steadily increased from 2009 to 2019.The existing knowledge concerning BE development has historically focused on men,but our findings show that the risk in women is not insignificant.
文摘Pancreatic cancer is usually associated with a poor prognosis.Surgery is the main curative treatment but pancreatic operations are aggressive and new tools that help clinicians to predict surgical and prognostic outcomes are necessary.Lu et al recently published a retrospective,single centre cohort study evaluating the impact of seven nutritional and inflammatory markers in pancreatic cancer surgical patients:The albumin-to-globulin ratio,prognostic nutritional index(PNI),systemic immune-inflammation index(SII),neutrophil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR),nutritional risk index,and the geriatric nutritional risk index.A significant correlation was found between the PNI,SII,NLR,and PLR and a hospital discharge of less than 15 days.In a univariable analysis,PNI,SII,NLR and PLR were significantly related to recurrence-free survival and,in a multivariable analysis PNI was associated with overall survival.Various meta-analyses corroborate the results in terms of prognosis but individual studies are discordant on their usefulness.Besides,the cut-off values for these markers vary significantly between studies and there are no clinical trials comparing them to identify the most relevant ones.These are limitations when implementing nutritional and inflammatory biomarkers into clinical practice and further studies are needed in order to answer these questions.
文摘Gastric cancer(GC)and gastroesophageal junction cancer(GEJC)represent a significant burden globally,with complications such as overt bleeding(OB)further exacerbating patient outcomes.A recent study by Yao et al evaluated the effectiveness and safety of systematic treatment in GC/GEJC patients presenting with OB.Using propensity score matching,the study balanced the comparison groups to investigate overall survival and treatment-related adverse events.The study's findings emphasize that systematic therapy can be safe and effective and contribute to the ongoing debate about the management of advanced GC/GEJC with OB,highlighting the complexities of treatment decisions in these high-risk patients.
文摘This editorial assesses the prognostic value of preoperative inflammatory and nutritional biomarkers in patients undergoing surgical resection for pancreatic cancer.Lu et al evaluated the ability of seven biomarkers to predict postoperative recovery and long-term outcomes.These biomarkers were albumin-to-globulin ratio,prognostic nutritional index(PNI),systemic immune-inflammation index,neutrophil-to-lymphocyte ratio,platelet-to-lymphocyte ratio,nutritional risk index,and geriatric nutritional risk index.The PNI was found to be a strong predictor of both overall and recurrence-free survival,underscoring its clinical relevance in managing patients with pancreatic cancer.

文摘The sine oculis homeobox homolog(SIX)family,a group of transcription factors characterized by a conserved DNA-binding homology domain,plays a critical role in orchestrating embryonic development and organogenesis across various organisms,including humans.Comprising six distinct members,from SIX1 to SIX6,each member contributes uniquely to the development and differentiation of diverse tissues and organs,underscoring the versatility of the SIX family.Dysregulation or mutations in SIX genes have been implicated in a spectrum of developmental disorders,as well as in tumor initiation and progression,highlighting their pivotal role in maintaining normal developmental trajectories and cellular functions.Efforts to target the transcriptional complex of the SIX gene family have emerged as a promising strategy to inhibit tumor development.While the development of inhibitors targeting this gene family is still in its early stages,the significant potential of such interventions holds promise for future therapeutic advances.Therefore,this review aimed to comprehensively explore the advancements in understanding the SIX family within gastrointestinal cancers,focusing on its critical role in normal organ development and its implications in gastrointestinal cancers,including gastric,pancreatic,colorectal cancer,and hepatocellular carcinomas.In conclusion,this review deepened the understanding of the functional roles of the SIX family and explored the potential of utilizing this gene family for the diagnosis,prognosis,and treatment of gastrointestinal cancers.
文摘BACKGROUND Proton pump inhibitors(PPIs)are widely used,including among cancer patients,to manage gastroesophageal reflux and other gastric acid-related disorders.Recent evidence suggests associations between long-term PPI use and higher risks for various adverse health outcomes,including greater mortality.AIM To investigate the association between PPI use and all-cause mortality among cancer patients by a comprehensive analysis after adjustment for various confounders and a robust methodological approach to minimize bias.METHODS This retrospective cohort study used data from the TriNetX research network,with electronic health records from multiple healthcare organizations.The study employed a new-user,active comparator design,which compared newly treated PPI users with non-users and newly treated histamine2 receptor antagonists(H2RA)users among adult cancer patients.Newly prescribed PPIs(esomeprazole,lansoprazole,omeprazole,pantoprazole,or rabeprazole)users were compared to non-users or newly prescribed H2RAs(cimetidine,famotidine,nizatidine,or ranitidine)users.The primary outcome was all-cause mortality.Each patient in the main group was matched to a patient in the control group using 1:1 propensity score matching to reduce confounding effects.Multivariable Cox regression models were used to estimate hazard ratios(HRs)and 95% confidence interval(CI).RESULTS During the follow-up period(median 5.4±1.8 years for PPI users and 6.5±1.0 years for non-users),PPI users demonstrated a higher all-cause mortality rate than non-users after 1 year,2 years,and at the end of follow up(HRs:2.34-2.72).Compared with H2RA users,PPI users demonstrated a higher rate of all-cause mortality HR:1.51(95%CI:1.41-1.69).Similar results were observed across sensitivity analyses by excluding deaths from the first 9 months and 1-year post-exposure,confirming the robustness of these findings.In a sensitivity analysis,we analyzed all-cause mortality outcomes between former PPI users and individuals who have never used PPIs,providing insights into the long-term effects of past PPI use.In addition,at 1-year follow-up,the analysis revealed a significant difference in mortality rates between former PPI users and non-users(HR:1.84;95%CI:1.82-1.96).CONCLUSION PPI use among cancer patients was associated with a higher risk of all-cause mortality compared to non-users or H2RA users.These findings emphasize the need for cautious use of PPIs in cancer patients and suggest that alternative treatments should be considered when clinically feasible.However,further studies are needed to corroborate our findings,given the significant adverse outcomes in cancer patients.

文摘BACKGROUND Patients with BRAF V600E mutant metastatic colorectal cancer(mCRC)have a low incidence rate,poor biological activity,suboptimal response to conventional treatments,and a poor prognosis.In the previous cohort study on mCRC conducted by our team,it was observed that integrated Chinese and Western medicine treatment could significantly prolong the overall survival(OS)of patients with colorectal cancer.Therefore,we further explored the survival benefits in the population with BRAF V600E mutant mCRC.AIM To evaluate the efficacy of integrated Chinese and Western medicine in the treatment of BRAF V600E mutant metastatic colorectal cancer.METHODS A cohort study was conducted on patients with BRAF V600E mutant metastatic colorectal cancer admitted to Xiyuan Hospital of China Academy of Chinese Medical Sciences and Traditional Chinese Medicine Hospital of Xinjiang Uygur Autonomous Region from January 2016 to December 2022.The patients were divided into two cohorts.RESULTS A total of 34 cases were included,with 23 in Chinese-Western medicine cohort(cohort A)and 11 in Western medicine cohort(cohort B).The median overall survival was 19.9 months in cohort A and 14.2 months in cohort B,with a statistically significant difference(P=0.038,hazard ratio=0.46).The 1-3-year survival rates were 95.65%(22/23),39.13%(9/23),and 26.09%(6/23)in cohort A,and 63.64%(7/11),18.18%(2/11),and 9.09%(1/11)in cohort B,respectively.Subgroup analysis showed statistically significant differences in median OS between the two cohorts in the right colon,liver metastasis,chemotherapy,and first-line treatment subgroups(P<0.05).CONCLUSION Integrated Chinese and Western medicine can prolong the survival and reduce the risk of death in patients with BRAF V600E mutant metastatic colorectal cancer,with more pronounced benefits observed in patients with right colon involvement,liver metastasis,combined chemotherapy,and first-line treatment.
文摘Objective: To analyze the incidence and mortality rates of esophagus cancer in China from 2008 to 2012.Methods: Incident and mortality cases of esophagus cancer were retrieved from the National Central Cancer Registry(NCCR) database collecting from 135 cancer registries in China during 2008-2012. The incidence and mortality rates of esophagus cancer were calculated by area(urban/rural), region(eastern, middle, western), gender and age group(0, 1-4, 5-84 by 5 years and 85+ years). China census in 2000 and Segi’s world population were applied for age-standardized rates. Joinpoint model was used for time-trend analysis.Results: The crude incidence rate of esophagus cancer was 22.57/100,000. The age-standardized incidence rates by China standard population(ASIRC) and by world standard population(ASIRW) were 14.58/100,000 and14.80/100,000, respectively. The crude mortality rate of esophagus cancer was 17.19/100,000. The agestandardized mortality rates by Chinese standard population(ASMRC) and by world standard population(ASMRW) were 10.80/100,000 and 10.86/100,000 respectively. Incidence and mortality rates of esophagus cancer were higher in males than in females and higher in rural areas than in urban areas. The crude incidence rate in middle areas was the highest among all areas, followed by western areas and eastern areas. The age-specific incidence rate of esophagus cancer was relatively low in age groups before 40 years old and then increased after 45 years old. It peaked in the age group of 80-84 years. The patterns of age-specific mortality rates of esophagus cancer were close to those of age-specific incidence rates. The ASIRC of esophagus cancer decreased dramatically by 29.87% between 2003 and 2012, from 14.33/100,000 to 10.05/100,000. The esophagus cancer incidence rate decreased by 3.76% per year(P>0.05). The mortality rate of esophagus cancer decreased annually over the decades from 2003 to 2012 in China(P>0.05). In females, the annual percentage change(APC) of mortality rate was-5.43%[95% confidence intervals(95% CI):-6.50%,-4.30%](P<0.05) and the mortality rate of esophagus cancer in rural females was statistically significant(APC:-3.20%, 95% CI:-4.20%,-2.20%)(P<0.05).Conclusions: The focus of prevention and treatment for esophagus cancer is strengthening primary prevention of esophageal cancer, and promoting esophagus cancer secondary prevention to reduce incidence and mortality rates of esophagus cancer, prolong survival rate of patients and decline the burden of esophagus cancer in China.
文摘Objective: To observe the clinical therapeutic effects of Rehmannia Oral Liquid on the syndrome of heat accumulation with Yin consumption in intermediate or late esophagus cancer patients undergoing radiotherapy. Methods: The IFN-α, TNF-α, IL-1β and TGF-β1 levels in sera were determined by the method of ABC-WLISA before and after the treatment with Rehmannia Oral Liquid. At the same time, the observation was carried out on the patient's general condition, symptoms and signs, barium meal or CT examinations, and biopsy. Another 30 cases of esophagus cancer were treated singly with radiotherapy as the control group. Results: Rehmannia Oral Liquid could obviously improve the patient's general condition, and the symptoms and signs after radiotherapy. Based on the X-ray examination and biopsy, the short-term local control rate of the treatment group and the control group was 70.0% and 40.0% respectively, showing a significant difference (P<0.05). Before the treatment, the level of serum IFN-α of both cancer groups was lower and the levels of TNF-α, IL-1β and TGF-β1 were higher than that of normal group. After treatment, the level of IFN-α in both treatment group and control group increased significantly (P<0.01), and the treatment group improved more obviously than the control group (P<0.05). The level of TNF-α of both groups decreased significantly (P<0.01) after treatment, and the level of IL-1β decreased in treatment group and increased in control group without the significant difference as compared with that before treatment. The level of TGF-β1 was significantly increased in control group (P<0.05) and decreased in treatment group (P>0.05) after treatment. The difference between groups was significant (P<0.05). Conclusion: Rehmannia Oral Liquid can obviously reduce the radiotherapy reaction, improve the quality of life, and raise the therapeutic effects. The action mechanism of the Liquid may lie in balancing the cytokine network and regulating the disordered signal transmission.
文摘A 91-year-old man was referred to our hospital with intermittent dysphagia. He had undergone esophagectomy for esophageal cancer(T3N2M0 Stage Ⅲ) 11 years earlier. Endoscopic examination revealed an anastomotic stricture; signs of inflammation,including redness,erosion,edema,bleeding,friability,and exudate with white plaques; and multiple depressions in the residual esophagus. Radiographical examination revealed numerous fine,gastrografinfilled projections and an anastomotic stricture. Biopsy specimens from the area of the anastomotic stricture revealed inflammatory changes without signs of malignancy. Candida glabrata was detected with a culture test of the biopsy specimens. The stricture was diagnosed as a benign stricture that was caused by esophageal intramural pseudodiverticulosis. Accordingly,endoscopic balloon dilatation was performed and antifungal therapy was started in the hospital. Seven weeks later,endoscopic examination revealed improvement in the mucosal inflammation; only the pseudodiverticulosis remained. Consequently,the patient was discharged. At the latest follow-up,the patient was symptomfree and the pseudodiverticulosis remained in the residual esophagus without any signs of stricture or inflammation.
文摘AIM To study factors associated with esophageal and nonesophageal cancer morbidity among Barrett's esophagus(BE) patients. METHODS A cohort study within a single tertiary center included 386 consecutive patients with biopsy proven BE, who were recruited between 2004-2014. Endoscopic and histologic data were prospectively recorded. Cancer morbidity was obtained from the national cancer registry. Main outcomes were BE related(defined as esophagus and cardia) and non-BE related cancers(all other cancers). Cancer incidence and all-causemortality were compared between patients with highgrade dysplasia(HGD) and with low-grade or no dysplasia(non-HGD) using Kaplan-Meier curves and cox regression models.RESULTS Of the 386 patients, 12 had HGD, 7 had a BE related cancer. There were 75(19.4%) patients with 86 cases of lifetime cancers, 76 of these cases were non-BE cancers. Seven(1.8%) and 18(4.7%) patients had BE and non-BE incident cancers, respectively. Twelve(3.1%) patients had HGD as worst histologic result. Two(16.7%) and 16(4.4%) incident non-BE cancers occurred in the HGD and non-HGD group, respectively. Ten-year any cancer and non-BE cancer free survival was 63% and 82% in the HGD group compared to 93% and 95% at the non-HGD group, respectively. Log-rank test for patients with more than one endoscopy, assuring longer follow up, showed a significant difference(P < 0.001 and P = 0.017 respectively). All-cause mortality was not significantly associated with BE HGD.CONCLUSION Patients with BE and HGD, may have a higher risk for all-cause cancer morbidity. The implications on cancer prevention recommendations should be further studied.

文摘Objective:To investigate the effect of radiotherapy plus recombinant human endostatin(RHendostatin) on esophageal cancer and its mechanism.Methods:A total of SO nudemice were equally randomized into control group,radiotherapy group,and combined therapy group Ⅰ,Ⅱ,and Ⅲ after inoculating with Ecal09 cell suspension(1×107 cells/mL).On the day of grouping,control group and radiotherapy group were injected normal saline,while radiotherapy group and 3 combined therapy groups received radiotherapy;besides,combined therapy group Ⅰ,Ⅱ,and Ⅲ was injected RH-endostatin of 2.5,5,10 mg/kg respectively.After 3-week therapy,the tumors of each group were collected and microvessel density and VEGF expression in tumors were determined.In vitro,Eca109 cells were divided into control group,radiotherapy group,and combined therapy group.Forty-eight hours after treatment cell cycle distribution and apoptosis rate were detected,and the activity of VEGF signal paths was semiquantitatively analyzed.Results:Since the 6th day of treatment,the relative tumor proliferation rate of combined therapy group Ⅱ was lower than radiotherapy group(P<0.05) and 40%since the 15 th day.Average microvessel density and EGFR expression in combined therapy group Ⅱ were lower than radiotherapy group(P<0.05).In vitro,the cell percentage in S and G2/M phase of combined therapy group cells was lower than that in radiotherapy group cells,while the apoptosis rate and the expression of VEGF,AKT,p-AKT,ERK1/2 and p-ERKl/2 in combined group were higher than that in radiotherapy group(P<0.05).Conclusions:RH-endostatin promotes the efficacy of radiotherapy on esophageal cancer,which may be partly realized by inhibiting the activity of VEGF related signal paths.
文摘Breast cancer can infrequently metastasize to the upper gastrointestinal(GI)tract but the exact incidence is not well established-there is considerable variation between incidence reported from clinical studies and incidence noted in autopsy series.Clinical presentation can be very non-specific and often mimics primary gastrointestinal conditions.Endoscopy alone may not be sufficient to make a diagnosis and misdiagnosis is also common.A high degree of awareness and clinical suspicion is required to establish metastases to the upper GI tract.We undertook a comprehensive review of the available literature on breast cancer metastases to the esophagus and stomach including the clinical symptoms and presentation,endoscopic features,additional diagnostic imaging modalities,treatment and outcomes.
文摘A 65-year-old man was admitted to our hospital following 6 months of dysphagia. At first, conventional endoscopy showed a reddish and depressed lesion in the stomach and an elevated lesion in the posterior wall of the hypopharynx. An endoscopic biopsy showed adenocarcinoma in the stomach, and squamous cell carcinoma in the hypopharynx. On the further examination, trans-nasal endoscopy with narrow band imaging (NBI) was performed. During the trumpet maneuver, a huge protruded lesion was observed and it reached to the orifice of the esophagus. Other superficial lesion located at left pyriform sinus was detected by NBI system as brownish area with brown dots. Furthermore, superficial esophageal cancer in the cervical esophagus was detected. Finally, 4 carcinomas in upper gastrointestinal tract were detected. Among them, the hypopharyngeal cancer was the most advanced (T3N0). The patient hoped to preserve his voice and swallowing function, endoscopic laryngo-pharyngeal surgery (ELPS) was performed for the hypopharyngeal cancer. Endoscopic mucosal resection (EMR) was performed for the esophageal cancer, and Endoscopic submucosal dissection (ESD) was performed for the gastric cancer. Under collaboration between a head and neck surgeon and an endoscopist, the tumor was resected en-bloc. The histopathological findings of hypopharyngeal cancer were squamous cell carcinoma, subeipthelial invasion, 29 × 28 × 4.2 mm. The others were diagnosed as mucosal cancers. The patient is currently alive with no recurrence at 28 months after the surgery;there is no stricture at the cervical esophagus. Endoscopic laryngopharyngeal surgery for the tumor of pharyngo-esophageal junction can provide a less invasive treatment.
文摘Since Barrett's esophagus is a precancerous condition,efforts have been made for its eradication by various ablative techniques.Initially,laser ablation was attempted in non-dysplastic Barrett's esophagus and subsequently,endoscopic ablation using photodynamic therapy was used in Barrett's patients with high-grade dysplasia who were poor surgical candidates.Since then,various ablative therapies have been developed with radiofrequency ablation having the best quality of evidence.Resection of dysplastic areas only without complete removal of entire Barrett's segment is associated with high risk of developing metachronous neoplasia.Hence,the current standard of management for Barrett's esophagus includes endoscopic mucosal resection of visible abnormalities followed by ablation to eradicate remaining Barrett's epithelium.Although endoscopic therapy cannot address regional lymph node metastases,such nodal involvement is present in only 1% to 2% of patients with intramucosal adenocarcinoma in Barrett esophagus and therefore is useful in intramucosal cancers.Post ablation surveillance is recommended as recurrence of intestinal metaplasia and dysplasia have been reported.This review includes a discussion of the technique,efficacy and complication rate of currently available ablation techniques such as radiofrequency ablation,cryotherapy,argon plasma coagulation and photodynamic therapy as well as endoscopic mucosal resection.A brief discussion of the emerging technique,endoscopic submucosal dissection is also included.
