Epithelial OC is the most predominant pathologic subtype, with five major histotypes that differ in origination,pathogenesis, molecular alterations, risk factors, and prognosis. Genetic susceptibility is manifested by rare inherited mutations with high to moderate penetrance. Genome-wide association studies have additionally identified 29 common susceptibility alleles for OC, including 14 subtype-specific alleles. Several reproductive and hormonal factors may lower risk, including parity, oral contraceptive use, and lactation, while others such as older age at menopause and hormone replacement therapy confer increased risks. These associations differ by histotype, especially for mucinous OC, likely reflecting differences in etiology. Endometrioid and clear cell OC share a similar, unique pattern of associations with increased risks among women with endometriosis and decreased risks associated with tubal ligation. OC risks associated with other gynecological conditions and procedures, such as hysterectomy,pelvic inflammatory disease, and polycystic ovarian syndrome, are less clear. Other possible risk factors include environmental and lifestyle factors such as asbestos and talc powder exposures, and cigarette smoking. The epidemiology provides clues on etiology,primary prevention, early detection, and possibly even therapeutic strategies.展开更多

This article provides the most up-to-date overview of colorectal cancer burden in China. Methods： Totally 234 cancer registries submitted data of 2011 to the National Central Cancer Registry （NCCR）. Qualified data from 177 registries was pooled and analyzed. The crude incidence and mortality rates of colorectal cancer were calculated by age, gender and geographic area. The numbers of new cases and deaths were estimated using the 5-year age-specific cancer incidence/mortality rates and the corresponding populations. China census in 2000 and Segi＇s world population were applied for age standardized rates. Results： The estimate of new cases diagnosed with colorectal cancer of China in 2011 was 310,244 （178,404 for males and 131,840 for females, 195,117 in urban areas and 115,128 in rural areas）, accounting for 9.20% of overall new cancer cases. The crude incidence of colorectal cancer ranked fourth in all cancer sites with rate of 23.03/100,000 （25.83/100,000 for males and 20.08/100,000 for female, 28.25/100,000 in urban areas and 17.54/100,000 in rural areas）. The age-standardized rates by China population and by World population were 16.79/100,000 and 16.52/100,000, respectively. The estimated number of colorectal cancer deaths of China in 2011 was 149,722 （86,427 for males and 63,295 for females, 91,682 in urban areas and 58,040 in rural areas）, accounting for 7.09% of overall cancer deaths. The crude mortality rate for colorectal cancer ranked fifth leading cause of cancer-related death in all cancer sites with rate of 11.11/100,000 （12.51/100,000 for males and 9.64/100,000 for female, 13.27/100,000 in urban areas and 8.84/100,000 in rural areas）. The age-standardized rates by China population and by World population for mortality were 7.77/100,000 and 7.66/100,000, respectively. For both of incidence and mortality, the rates of colorectal cancer were much higher in males than in females, and in rural areas than in urban areas. The rate of colorectal cancer increased greatly with age, especially after 40 or 45 years old. Conclusions： Colorectal cancer is a relative common cancer in China, especially for males in urban areas. Targeted prevention and early detection programs should be carried out.展开更多

A vast amount of study data on gastric cancer screening and early diagnosis has been accumulated in and out of China in the past decades. The practice of gastric cancer screening has also been efficiently carried out in different countries and regions. However, no widely accepted principle of population screening for gastric cancer has been developed yet. Screening for gastric cancer requires extensive exploration both theoretically and practically. This article focuses on the method and program of gastric cancer screening based on population. Moreover, the current situation of gastric cancer screening and its evaluation are evaluated.展开更多

Conversely, ...The immune system plays a complex role in the development and progression of pancreatic cancer. Inflammation can promote the formation of premalignant lesions and accelerate pancreatic cancer development. Conversely, pancreatic cancer is characterized by an immunosuppressive environment, which is thought to promote tumor progression and invasion. Here we review the current literature describing the role of the immune response in the progressive development of pancreatic cancer, with a focus on the mechanisms that drive recruitment and activation of immune cells at the tumor site, and our current understanding of the function of the immune cell types at the tumor. Recent clinical and preclinical data are reviewed, detailing the involvement of the immune response in pancreatitis and pancreatic cancer, including the role of specific cytokines and implications for disease outcome. Acute pancreatitis is characterized by a predominantly innate immune response, while chronic pancreatitis elicits an immune response that involves both innate and adaptive immune cells, and often results in profound sys-temic immune-suppression. Pancreatic adenocarcinoma is characterized by marked immune dysfunction driven by immunosuppressive cell types, tumor-promoting immune cells, and defective or absent inflammatory cells. Recent studies reveal that immune cells interact with cancer stem cells and tumor stromal cells, and these interactions have an impact on development and progression of pancreatic ductal adenocarcinoma(PDAC). Finally, current PDAC therapies are reviewed and the potential for harnessing the actions of the immune response to assist in targeting pancreatic cancer using immunotherapy is discussed.展开更多

We investigated whether early detection and improved treatments changed the patterns of characteristics,management and outcomes of young breast cancer patients over time.Methods: Females under 40 years of age diagnosed with breast cancer during the periods 1999-2017 and1999-2015 were identified in the Fudan University Shanghai Cancer Center(FUSCC) and the population-based Surveillance, Epidemiology, and End Results(SEER) registry, respectively. Clinicopathologic characteristics and treatment information were collected. Patients diagnosed before 2013 were followed up.Results: The proportions of young breast cancer patients were 15.0% and 5.3% in the FUSCC and SEER cohorts, respectively. In the FUSCC cohort, there was a significant increase in the proportion of ductal carcinoma in situ(DCIS)(from 8.8% to 16.9%;P<0.0001) and it remained stable in SEER cohort. The proportion of T1-stage tumors increased dramatically in the FUSCC cohort(from 35.3% to 41.9%;P=0.008), whereas it decreased in SEER cohort(from 42.4% to 33.0%;P<0.0001). The percentage of estrogen receptor(ER)-positive cancers was consistently increased in both the invasive ductal carcinoma(IDC) and DCIS patients in the two cohorts. Breastconserving surgery and immediate implant reconstruction after mastectomy both exhibited increased use over time in the FUSCC cohort. Both the FUSCC and SEER cohorts showed a significantly better prognosis in the recent time period.Conclusions: With the increased early-stage and ER-positive diseases in young patients as well as better systemic treatment strategies, improved survival has been observed in recent years. There has been a substantial deescalation in surgical therapies in young breast cancer patients.展开更多

GC is a major malignancy globally, and nearly half of GC cases and specific deaths worldwide occur in China;moreover, GC is frequently diagnosed in local advanced or advanced stages with poor prognosis3-5. GC progression is known to involve a multi-stage evolutionary cascade from precancerous gastric lesions, thus theoretically enabling the identification of high-risk populations and early detection of GC6.展开更多

Methods： A total of 5,382 local residents aged 40-69 years from three high-risk areas in China （Linzhou in Henan province, Feicheng in Shandong province and Cixian in Hebei province） from 2008 to 2011 were recruited in this population-based screening study. And 2,526 subjects declined to receive endoscopic biopsy examination with Lugol＇s iodine staining, while 9 and 815 subjects were excluded from liquid-based cytology and DNA-ICM test respectively due to slide quality. Finally, 2,856, 5,373 and 4,567 subjects were enrolled in the analysis for endoscopic biopsy examination, liquid-based cytology and DNA-ICM test, respectively. Sensitivity （SE）, specificity （SP）, negative predictive values （NPV） and positive predictive values （PPV） as well as their 95% confidence intervals （95% CI） for DNA-ICM, liquid-based cytology and the combination of the two methods were calculated. Receiver operating characteristic （ROC） curves were applied to determine the cutoff point of DNA-ICM for esophageal cancer. Results： DNA-ICM results were significantly correlative with esophageal cancer and precancer lesions （X2= 18.016, P〈0.001）. The cutoff points were 5,802, 5,803 and 8,002 based on dissimilar pathological types of low grade intraepithelial neoplasia （LGIN）, high grade intraepithelial neoplasia （HGIN）, and ESCC, respectively, and 5,803 was chosen in this study considering the SE and SP. The SE, SP, PPV, NPV of DNA-ICM test （cutoff point 5,803） combined with liquid-based cytology [threshold atypical squamous cells of undetermined significance （ASCUS）] were separately 72.1% （95% CI： 70.3%-73.9%）, 43.3% （95% CI. 41.3%-45.3%）, 22.8% （95% CI： 21.1%-24.5%） and 87.0% （95% CI： 85.7%-88.3%） for LGIN, 85.7% （95% CI： 84.3%-87.1%）, 41.3% （95% CI： 39.3%-43.3%）, 4.6% （95% CI： 3.8%-5.4%） and 98.9% （95% CI： 98.5%-99.3%） for HGIN, and 96.0% （95% CI： 95.2%-96.8%）, 40.8% （95% CI： 38.8%-42.8%）, 1.7% （95% CI： 1.2%-2.2%） and 99.9% （95% CI： 99.8%-100.0%） for ESCC. Conclusions： It is possible to use DNA-ICM test as a primary screening method before endoscopic screening for esophageal cancer.展开更多

文摘Objective:Based on multistage metabolomic profiling and Mendelian randomization analyses,the current study identified plasma metabolites that predicted the risk of developing gastric cancer(GC)and determined whether key metabolite levels modified the GC primary prevention effects.Methods:Plasma metabolites associated with GC risk were identified through a case-control study.Bi-directional two-sample Mendelian randomization analyses were performed to determine potential causal relationships utilizing the Shandong Intervention Trial(SIT),a nested case-control study of the Mass Intervention Trial in Linqu,Shandong province(MITS),China,the UK Biobank,and the Finn Gen project.Results:A higher genetic risk score for plasma L-aspartic acid was significantly associated with an increased GC risk in the northern Chinese population(SIT:HR=1.26 per 1 SD change,95%CI:1.07±1.49;MITS:HR=1.07,95%CI:1.00±1.14)and an increased gastric adenocarcinoma risk in Finn Gen(OR=1.68,95%CI:1.16±2.45).Genetically predicted plasma L-aspartic acid levels also modified the GC primary prevention effects with the beneficial effect of Helicobacter pylori eradication notably observed among individuals within the top quartile of L-aspartic acid level(P-interaction=0.098)and the beneficial effect of garlic supplementation only for those within the lowest quartile of L-aspartic acid level(P-interaction=0.02).Conclusions:Elevated plasma L-aspartic acid levels significantly increased the risk of developing GC and modified the effects of GC primary prevention.Further studies from other populations are warranted to validate the modification effect of plasma L-aspartic acid levels on GC prevention and to elucidate the underlying mechanisms.

文摘Gastric cancer(GC)is a prevalent and devastating disease with a poor prognosis.The lack of biomarkers for early detection and effective targeted therapeutics for GC patients represents two major challenges.Through isobaric tags for relative and absolute quantitation(iTRAQ)coupled with liquid chromatography-tandem mass spectrometry(LC-MS/MS)phosphoproteomic analysis of 14 GC and gastric epithelial cell lines,we discovered the discoidin domain receptor tyrosine kinase 1(DDR1)as a top potential drug target out of 40 tyrosine kinases detected along with over 1000 phosphoproteins profiled.The DDR1 protein and mRNA levels were upregulated in GC cells concurrent with DDR1 gene amplification.Immunohistochemistry staining of more than 200 clinical samples revealed that DDR1 was overexpressed in approximately 41%and 48%of the intestinal and diffuse types of GC cases,respectively,compared with only 3.5%in normal tissues.Higher DDR1 expression was associated with poor prognosis.In cellular models,DDR1 overexpression led to accelerated proliferation,invasion,and malignant transformation,putatively via inhibition of the Hippo pathway and consequent activation of YAP-TEAD target gene expression.Notably,DDR1-overexpressing GC cells exhibited high vulnerability to selective DDR1 inhibitors.The present study provides preclinical support for the application of DDR1-selective inhibitors in DDR1-overexpressing GC.

文摘Objective:To evaluate the impact of government-organized screening on the economic burden among patients with cervical cancer and precancerous lesions,and explore mediating pathways across diagnosis,initial treatment,radiotherapy/chemotherapy,follow-up,and recurrence/progression/metastasis.Methods:A multicentre,nationwide survey across 5 disease courses was conducted from 26 hospitals in China.Multivariable regression and structural equation modeling were used to assess the effects of government-organized screening on economic burden by comparing government-organized screening with workplace check-up,self-paid check-up,and symptom-based detection.Results:Workplace check-up,self-paid check-up,and symptom-based detection were associated with progressively higher costs across diagnosis[β:1.10,95%confidence interval(CI):0.54±1.67;β:1.46,95%CI:1.00±1.92;andβ:1.68,95%CI:1.25±2.11,respectively],initial treatment(β:0.36,95%CI:0.18±0.55;β:0.51,95%CI:0.35±0.66;andβ:0.56,95%CI:0.42±0.70,respectively),and follow-up(β:0.63,95%CI:0.38±0.88;β:0.83,95%CI:0.61±1.04;andβ:0.85,95%CI:0.65±1.06,respectively)compared to government-organized screening(all P<0.05).Earlier clinical staging and greater use of lower-level hospitals mediated 44.74%±54.97%of cost differences in diagnosis,73.27%±85.04%in initial treatment,and 30.38%±54.73%in follow-up.Fifteen percent of the cost differences during initial treatment were related to lower overtreatment for precancerous lesions.Conclusions:Government-led cervical cancer screening was associated with lower economic burden with pathways involving earlier-stage diagnosis,reduced overtreatment,and decreased reliance on higher-level hospitals,suggesting potential clinical benefits,efficient resource use,and improved equity in cancer care.

文摘Objective:The key molecular events signifying the Helicobacter pylori-induced gastric carcinogenesis process are largely unknown.Methods:Bulk tissue-proteomics profiling were leveraged across multi-stage gastric lesions from Linqu(n=166)and Beijing sets(n=99)and single-cell transcriptomic profiling(n=18)to decipher key molecular signatures of H.pylori-related gastric lesion progression and gastric cancer(GC)development.The association of key proteins association with gastric lesion progression and GC development were prospectively studied building on follow-up of the Linqu set and UK Biobank(n=48,529).Results:Concordant proteomics signatures associated with H.pylori infection and gastric carcinogenesis(ρ=0.784,correlation P=1.80×10^(−36))were identified.RNA expression of genes encoding 13 up-and 15 down-regulated key proteins displayed trending alterations in the transition from normal gastric epithelium to intestinal metaplasia,then to malignant cells.A 15-tissue protein panel integrating these signatures demonstrated potential for targeting individuals at high risk for progressing to gastric neoplasia(OR=7.22,95%CI:1.31-39.72 for the high-score group).A 4-circulating protein panel may be used as non-invasive markers predicting the risk of GC development(hazard ratio=3.73,95%confidence interval:1.63-8.54,high-risk vs.low-risk populations,area under the curve=0.75).Conclusions:Concordant proteomics signatures associated with H.pylori infection and gastric carcinogenesis were unveiled with potential as biomarkers for targeted prevention strategies.
文摘BACKGROUND Pancreatic cancer has an extremely poor prognosis.Although surgery is the firstline treatment for pancreatic cancer,its role is ultimately limited because patients often present too late for resection.Thus,multidisciplinary treatment approaches are needed.In particular,chemotherapy,targeted therapy,and immunotherapy can be ineffective for locally advanced pancreatic cancer(LAPC)because of its resistance to these modalities,but cryoablation has shown significant promise for treating this entity and prolonging survival.AIM To investigate the safety and efficacy of cryoablation for LAPC.METHODS Clinical and laboratory data,including surgical procedure,postoperative complications,immunobiochemical markers(e.g.,carbohydrate antigen 19-9),and followup visits,of 24 LAPC patients treated with cryoablation at the department of hepatobiliary and pancreatic surgery of our hospital from January 2023 to December 2024 were retrospectively analyzed.RESULTS Surgery was smooth in all patients,with no perioperative deaths.Postoperative pancreatic fistulas occurred in 18 patients(75.0%),including biochemical leak in 14 cases and grade B(fistula)in 4 cases.Three patients(12.5%)had delayed gastric emptying.The carbohydrate antigen 19-9 level remained low on postoperative day 30(P<0.05).Immune markers(natural killer cells and tumor necrosis factor-alpha)significantly increased on days 7 and 30(P<0.01 or P<0.05),whereas cluster of differentiation CD4+T cells levels on day 30 significantly differed from baseline.Day 30 pain scores were significantly lower than preoperative ones(P<0.01).Tumor volume was reduced on postoperative computed tomography.Survival was prolonged.The overall survival time of LAPC patients treated with cryoablation was 16.8 months.CONCLUSION Cryoablation can directly inactivate LAPC and boost immunity,thus delaying tumor progression,alleviating pain,improving quality of life,and prolonging survivals.Therefore,it is a safe and effective treatment option for LAPC.
文摘BACKGROUND Ovarian cancer(OC)is the most lethal gynecological cancer among females,and its early diagnosis could help for better outcomes of the patients.AIM To investigate the utility of serum insulin-like growth factors-binding proteins 2(IGFBP2),secreted phosphoprotein 1(SPP1),thrombospondin 1 protein(TSP1)and D-dimer levels in addition to currently used biomarkers[cancer antigen 125(CA125)and human epididymis protein 4(HE4)]in the diagnosis of epithelial OC(EOC).METHODS This is a case-control study that included fifty females diagnosed with EOC,10 females with benign ovarian masses recruited from the Egyptian National Cancer Institute,and 30 healthy females as a control group.All subjects were assessed for serum HE4,CA125,IGFBP2,TSP1 and SPP1 measurement by enzyme-linkedimmunosorbent assay.RESULTS There was a statistically significant difference in serum levels between EOC,benign ovarian masses,and healthy control groups regarding CA125 and SPP1(P<0.001 for both markers),while HE4 and IGFBP2 increased significantly in EOC compared to healthy control groups(P<0.001 for all markers)with no significant difference between EOC and benign ovarian masses groups.However,there was no statistically significant difference among EOC,benign ovarian masses,and healthy control groups regarding the TSP1 serum levels(P=0.051).Receiver operating characteristic analysis revealed that combined assessment of SPP1 with CA125 or TSP1 increased the diagnosis of EOC patients to a sensitivity,specificity,and area under curve of(93.3%,100%,0.968;respectively,P<0.001).CONCLUSION SPP1 may be a potential marker for the differentiation between benign and malignant ovarian masses,while IGFBP2 can differentiate between healthy females and females with ovarian masses.Combining SPP1 with CA125 or TSP1 provides high sensitivity and specificity for the detection of EOC patients.

文摘Background:Dysregulation of enhancer transcription occurs in multiple cancers.Enhancer RNAs(eRNAs)are transcribed products from enhancers that play critical roles in transcriptional control.Characterizing the genetic basis of eRNA expression may elucidate the molecular mechanisms underlying cancers.Methods:Initially,a comprehensive analysis of eRNA quantitative trait loci(eRNAQTLs)was performed in The Cancer Genome Atlas(TCGA),and functional features were characterized using multi-omics data.To establish the first eRNAQTL profiles for colorectal cancer(CRC)in China,epigenomic data were used to define active enhancers,which were subsequently integrated with transcription and genotyping data from 154 paired CRC samples.Finally,largescale case-control studies(34,585 cases and 69,544 controls)were conducted along with multipronged experiments to investigate the potential mechanisms by which candidate eRNAQTLs affect CRC risk.Results:A total of 300,112 eRNAQTLs were identified across 30 different cancer types,which exert their influence on eRNA transcription by modulating chromatin status,binding affinity to transcription factors and RNA-binding proteins.These eRNAQTLs were found to be significantly enriched in cancer risk loci,explaining a substantial proportion of cancer heritability.Additionally,tumor-specific eRNAQTLs exhibited high responsiveness to the development of cancer.Moreover,the target genes of these eRNAs were associated with dysregulated signaling pathways and immune cell infiltration in cancer,highlighting their potential as therapeutic targets.Furthermore,multiple ethnic population studies have confirmed that an eRNAQTL rs3094296-T variant decreases the risk of CRC in populations from China(OR=0.91,95%CI 0.88–0.95,P=2.92×10^(-7))and Europe(OR=0.92,95%CI 0.88–0.95,P=4.61×10^(-6)).Mechanistically,rs3094296 had an allele-specific effect on the transcription of the eRNA ENSR00000155786,which functioned as a transcriptional activator promoting the expression of its target gene SENP7.These two genes synergistically suppressed tumor cell proliferation.Our curated list of variants,genes,and drugs has been made available in CancereRNAQTL(http://canernaqtl.whu.edu.cn/#/)to serve as an informative resource for advancing this field.Conclusion:Our findings underscore the significance of eRNAQTLs in transcriptional regulation and disease heritability,pinpointing the potential of eRNA-based therapeutic strategies in cancers.
文摘Alterations in the mesenchymal-epithelial transition factor(MET)gene are critical drivers of non-small cell lung cancer(NSCLC).In recent years advances in precision therapies targeting MET alterations have significantly expanded treatment options for NSCLC patients.These alterations include MET exon 14 skipping mutations(MET exon 14 skipping),MET gene amplifications,MET point mutations(primarily kinase domain mutations),and MET protein overexpression.Accurate identification of these alterations and appropriate selection of patient populations and targeted therapies are essential for improving clinical outcomes.The East China Lung Cancer Group,Youth Committee(ECLUNG YOUNG,Yangtze River Delta Lung Cancer Cooperation Group)has synthesized insights from China’s innovative drug development landscape and clinical practice to formulate an expert consensus on the diagnosis and treatment of NSCLC patients with MET alterations.This consensus addresses key areas,such as optimal testing timing,testing methods,testing strategies,quality control measures,and treatment approaches.By offering standardized recommendations,this guidance aims to streamline diagnostic and therapeutic processes and enhance clinical decision-making for NSCLC with MET alterations.
文摘Ovarian cancer(OC) is the seventh most commonly diagnosed cancer among women in the world and the tenth most common in China. Epithelial OC is the most predominant pathologic subtype, with five major histotypes that differ in origination,pathogenesis, molecular alterations, risk factors, and prognosis. Genetic susceptibility is manifested by rare inherited mutations with high to moderate penetrance. Genome-wide association studies have additionally identified 29 common susceptibility alleles for OC, including 14 subtype-specific alleles. Several reproductive and hormonal factors may lower risk, including parity, oral contraceptive use, and lactation, while others such as older age at menopause and hormone replacement therapy confer increased risks. These associations differ by histotype, especially for mucinous OC, likely reflecting differences in etiology. Endometrioid and clear cell OC share a similar, unique pattern of associations with increased risks among women with endometriosis and decreased risks associated with tubal ligation. OC risks associated with other gynecological conditions and procedures, such as hysterectomy,pelvic inflammatory disease, and polycystic ovarian syndrome, are less clear. Other possible risk factors include environmental and lifestyle factors such as asbestos and talc powder exposures, and cigarette smoking. The epidemiology provides clues on etiology,primary prevention, early detection, and possibly even therapeutic strategies.
文摘Objective： Colorectal cancer is the third most common type of cancer and the fourth leading cause of cancer-related death in the world. This article provides the most up-to-date overview of colorectal cancer burden in China. Methods： Totally 234 cancer registries submitted data of 2011 to the National Central Cancer Registry （NCCR）. Qualified data from 177 registries was pooled and analyzed. The crude incidence and mortality rates of colorectal cancer were calculated by age, gender and geographic area. The numbers of new cases and deaths were estimated using the 5-year age-specific cancer incidence/mortality rates and the corresponding populations. China census in 2000 and Segi＇s world population were applied for age standardized rates. Results： The estimate of new cases diagnosed with colorectal cancer of China in 2011 was 310,244 （178,404 for males and 131,840 for females, 195,117 in urban areas and 115,128 in rural areas）, accounting for 9.20% of overall new cancer cases. The crude incidence of colorectal cancer ranked fourth in all cancer sites with rate of 23.03/100,000 （25.83/100,000 for males and 20.08/100,000 for female, 28.25/100,000 in urban areas and 17.54/100,000 in rural areas）. The age-standardized rates by China population and by World population were 16.79/100,000 and 16.52/100,000, respectively. The estimated number of colorectal cancer deaths of China in 2011 was 149,722 （86,427 for males and 63,295 for females, 91,682 in urban areas and 58,040 in rural areas）, accounting for 7.09% of overall cancer deaths. The crude mortality rate for colorectal cancer ranked fifth leading cause of cancer-related death in all cancer sites with rate of 11.11/100,000 （12.51/100,000 for males and 9.64/100,000 for female, 13.27/100,000 in urban areas and 8.84/100,000 in rural areas）. The age-standardized rates by China population and by World population for mortality were 7.77/100,000 and 7.66/100,000, respectively. For both of incidence and mortality, the rates of colorectal cancer were much higher in males than in females, and in rural areas than in urban areas. The rate of colorectal cancer increased greatly with age, especially after 40 or 45 years old. Conclusions： Colorectal cancer is a relative common cancer in China, especially for males in urban areas. Targeted prevention and early detection programs should be carried out.
文摘Screening and early diagnosis of gastric cancer play important roles in reducing the mortality of gastric cancer. A vast amount of study data on gastric cancer screening and early diagnosis has been accumulated in and out of China in the past decades. The practice of gastric cancer screening has also been efficiently carried out in different countries and regions. However, no widely accepted principle of population screening for gastric cancer has been developed yet. Screening for gastric cancer requires extensive exploration both theoretically and practically. This article focuses on the method and program of gastric cancer screening based on population. Moreover, the current situation of gastric cancer screening and its evaluation are evaluated.

文摘The immune system plays a complex role in the development and progression of pancreatic cancer. Inflammation can promote the formation of premalignant lesions and accelerate pancreatic cancer development. Conversely, pancreatic cancer is characterized by an immunosuppressive environment, which is thought to promote tumor progression and invasion. Here we review the current literature describing the role of the immune response in the progressive development of pancreatic cancer, with a focus on the mechanisms that drive recruitment and activation of immune cells at the tumor site, and our current understanding of the function of the immune cell types at the tumor. Recent clinical and preclinical data are reviewed, detailing the involvement of the immune response in pancreatitis and pancreatic cancer, including the role of specific cytokines and implications for disease outcome. Acute pancreatitis is characterized by a predominantly innate immune response, while chronic pancreatitis elicits an immune response that involves both innate and adaptive immune cells, and often results in profound sys-temic immune-suppression. Pancreatic adenocarcinoma is characterized by marked immune dysfunction driven by immunosuppressive cell types, tumor-promoting immune cells, and defective or absent inflammatory cells. Recent studies reveal that immune cells interact with cancer stem cells and tumor stromal cells, and these interactions have an impact on development and progression of pancreatic ductal adenocarcinoma(PDAC). Finally, current PDAC therapies are reviewed and the potential for harnessing the actions of the immune response to assist in targeting pancreatic cancer using immunotherapy is discussed.

文摘Objective: Breast cancer in young females was usually considered more aggressive and requires aggressive therapy. We investigated whether early detection and improved treatments changed the patterns of characteristics,management and outcomes of young breast cancer patients over time.Methods: Females under 40 years of age diagnosed with breast cancer during the periods 1999-2017 and1999-2015 were identified in the Fudan University Shanghai Cancer Center(FUSCC) and the population-based Surveillance, Epidemiology, and End Results(SEER) registry, respectively. Clinicopathologic characteristics and treatment information were collected. Patients diagnosed before 2013 were followed up.Results: The proportions of young breast cancer patients were 15.0% and 5.3% in the FUSCC and SEER cohorts, respectively. In the FUSCC cohort, there was a significant increase in the proportion of ductal carcinoma in situ(DCIS)(from 8.8% to 16.9%;P<0.0001) and it remained stable in SEER cohort. The proportion of T1-stage tumors increased dramatically in the FUSCC cohort(from 35.3% to 41.9%;P=0.008), whereas it decreased in SEER cohort(from 42.4% to 33.0%;P<0.0001). The percentage of estrogen receptor(ER)-positive cancers was consistently increased in both the invasive ductal carcinoma(IDC) and DCIS patients in the two cohorts. Breastconserving surgery and immediate implant reconstruction after mastectomy both exhibited increased use over time in the FUSCC cohort. Both the FUSCC and SEER cohorts showed a significantly better prognosis in the recent time period.Conclusions: With the increased early-stage and ER-positive diseases in young patients as well as better systemic treatment strategies, improved survival has been observed in recent years. There has been a substantial deescalation in surgical therapies in young breast cancer patients.

文摘In this review,we offer a concise overview of liver cancer epidemiology in China and worldwide from the official databases of GLOBOCAN 2020 and the National Cancer Registry in China.We also summarized the evidence for the main risk factors associated with liver cancer risk and discuss strategies implemented in China to control the liver cancer burden.Overall,liver cancer was the sixth most commonly diagnosed cancer and the third leading cause of cancer-related death worldwide in 2020.Although China contributed to nearly half of cases across the world alone,the incidence and mortality rates of liver cancer presented a declining trend owing to the persistent efforts from the governments at all levels.The current liver cancer burden in China still faces an arduous challenge due to the relatively large population base as well as the substantially low survival rate(12.1%).To better control the liver cancer burden with the lowest cost,specific measures should be conducted by reducing exposure to established risk factors such as hepatitis B infection and aflatoxin.The promotion of surveillance is also an important method to prolong the survival of liver cancer.This review will provide basic information for future direction on the control of liver cancer burden.

文摘China is faced with heavy burdens caused by lung cancer,which has climbed to the top of both cancer incidence and mortality spectrums.The age-standardized rates of incidence and mortality have shown a trend of gradual uptrends in the last decades,while the crude rates rise much quickly due to the aging of population.Although the improvement in health care has contributed to better survival of lung cancer,its prognosis is still challenging.Apart from the common risk factors such as tobacco use,air pollution,and occupational hazards,some specific factors like Chinese-style cooking also have posed great threats to human health.In light of such national conditions,specific interventions should be conducted to curb the burden of lung cancer including smoking cessation,improvement of air quality,early detection and effective treatment of lung cancer.

文摘AIM:To clarify the similarities and differences in gastric cancer epidemiology between Japan and China.METHODS:A comprehensive literature search of the PubMed database was performed.The relevant literature published in China was also been cited.Data on incidence and mortality rates in 2008 were obtained from the Cancer Mondial database,published by International Agency for Research on Cancer at http://www-dep.iarc.fr/.RESULTS:Gastric cancer remains a significant publichealth burden in both Japan and China.The prevalence of Helicobacter pylori(H.pylori)colonization is high in the adult populations of both countries.Accumulating evidence from intervention studies in both countries has shown the effectiveness of H.pylori eradication in reduc-ing gastric cancer incidence.There are differences,however,in many aspects of gastric cancer,including patterns of incidence and mortality,trends in the prevalence of H.pylori infection,H.pylori strains,the magnitude of risk of gastric cancer related to H.pylori infection,and associations with dietary habits.Compared with China,Japan has seen a more rapid decline in H.pylori infection among adolescents.While Japanese cohort studies have dominated the literature concerning the associations between gastric cancer and dietary habits,numerous case-control studies in China suggest a positive association between a high intake of preserved fish and vegetables and gastric cancer risk.There is a need for a multidisciplinary research approach to understand the interactions between various strains of H.pylori,host factors,and other lifestyle and environmental factors in gastric carcinogenesis in both countries.CONCLUSION:The shared high incidence of gastric cancer and high prevalence of H.pylori,as well as differences in many aspects of gastric cancer,provide an excellent opportunity to establish Sino-Japanese collaborations.

文摘In the past decade, the Chinese government has committed to promoting gastric cancer (GC) prevention and control1,2. GC is a major malignancy globally, and nearly half of GC cases and specific deaths worldwide occur in China;moreover, GC is frequently diagnosed in local advanced or advanced stages with poor prognosis3-5. GC progression is known to involve a multi-stage evolutionary cascade from precancerous gastric lesions, thus theoretically enabling the identification of high-risk populations and early detection of GC6.

文摘Objective:Upper gastrointestinal(UGI)cancers,predominantly gastric cancer(GC)and esophageal cancer(EC),are malignant tumor types with high morbidity and mortality rates.Accumulating studies have focused on metabolomic profiling of UGI cancers in recent years.In this systematic review,we have provided a collective summary of previous findings on metabolites and metabolomic profiling associated with GC and EC.Methods:A systematic search of three databases(Embase,PubMed,and Web of Science)for molecular epidemiologic studies on the metabolomic profiles of GC and EC was conducted.The Newcastle–Ottawa Scale(NOS)was used to assess the quality of the included articles.Results:A total of 52 original studies were included for review.A number of metabolites were differentially distributed between GC and EC cases and non-cases,including those involved in glycolysis,anaerobic respiration,tricarboxylic acid cycle,and protein and lipid metabolism.Lactic acid,glucose,citrate,and fumaric acid were among the most frequently reported metabolites of cellular respiration while glutamine,glutamate,and valine were among the most commonly reported amino acids.The lipid metabolites identified previously included saturated and unsaturated free fatty acids,aldehydes,and ketones.However,the key findings across studies to date have been inconsistent,potentially due to limited sample sizes and the majority being hospital-based case-control analyses lacking an independent replication group.Conclusions:Studies on metabolomics have thus far provided insights into etiological factors and biomarkers for UGI cancers,supporting the potential of applying metabolomic profiling in cancer prevention and management efforts.

文摘Objective： To evaluate the feasibility of DNA image cytometry （DNA-ICM） as a primary screening method for esophageal squamous cell cancer （ESCC）. Methods： A total of 5,382 local residents aged 40-69 years from three high-risk areas in China （Linzhou in Henan province, Feicheng in Shandong province and Cixian in Hebei province） from 2008 to 2011 were recruited in this population-based screening study. And 2,526 subjects declined to receive endoscopic biopsy examination with Lugol＇s iodine staining, while 9 and 815 subjects were excluded from liquid-based cytology and DNA-ICM test respectively due to slide quality. Finally, 2,856, 5,373 and 4,567 subjects were enrolled in the analysis for endoscopic biopsy examination, liquid-based cytology and DNA-ICM test, respectively. Sensitivity （SE）, specificity （SP）, negative predictive values （NPV） and positive predictive values （PPV） as well as their 95% confidence intervals （95% CI） for DNA-ICM, liquid-based cytology and the combination of the two methods were calculated. Receiver operating characteristic （ROC） curves were applied to determine the cutoff point of DNA-ICM for esophageal cancer. Results： DNA-ICM results were significantly correlative with esophageal cancer and precancer lesions （X2= 18.016, P〈0.001）. The cutoff points were 5,802, 5,803 and 8,002 based on dissimilar pathological types of low grade intraepithelial neoplasia （LGIN）, high grade intraepithelial neoplasia （HGIN）, and ESCC, respectively, and 5,803 was chosen in this study considering the SE and SP. The SE, SP, PPV, NPV of DNA-ICM test （cutoff point 5,803） combined with liquid-based cytology [threshold atypical squamous cells of undetermined significance （ASCUS）] were separately 72.1% （95% CI： 70.3%-73.9%）, 43.3% （95% CI. 41.3%-45.3%）, 22.8% （95% CI： 21.1%-24.5%） and 87.0% （95% CI： 85.7%-88.3%） for LGIN, 85.7% （95% CI： 84.3%-87.1%）, 41.3% （95% CI： 39.3%-43.3%）, 4.6% （95% CI： 3.8%-5.4%） and 98.9% （95% CI： 98.5%-99.3%） for HGIN, and 96.0% （95% CI： 95.2%-96.8%）, 40.8% （95% CI： 38.8%-42.8%）, 1.7% （95% CI： 1.2%-2.2%） and 99.9% （95% CI： 99.8%-100.0%） for ESCC. Conclusions： It is possible to use DNA-ICM test as a primary screening method before endoscopic screening for esophageal cancer.
