METHODS: A total of 372 cases were selected from a cohort study in Linqu County, a high risk area for gastric cancer (GC) in northern China. To obtain a sufficient group size, patients with normal or superficial gastritis were included. Based on an average follow-up period of 56 mo, the 372 cases were divided into no progres-sion group (no histological progression from normal or superficial gastritis, n = 137), group Ⅰ (progressed from normal or superficial gastritis to SCAG, n = 134) and group Ⅱ (progressed from normal or superficial gastritis to IM, n = 101). IL-8 , MIF gene polymorphisms were detected by polymerase chain reaction-based denaturing high-performance liquid chromatography analysis and DNA sequencing. RESULTS: An increased risk of SCAG was found in subjects with IL-8-251 AA genotype [odds ratio (OR) = 2.62, 95% CI: 1.23-5.72] or IL-8-251 A allele carriers (AA + AT) (OR = 1.81, 95% CI: 1.06-3.09). An elevated risk of IM was found in subjects with IL-8-251 AT genotype (OR = 2.27, 95% CI: 1.25-4.14) or IL-8-251 A allele carriers (OR = 2.07, 95% CI: 1.16-3.69). An increased risk of SCAG was found in subjects with MIF-173 GC genotype (OR = 2.36, 95% CI: 1.38-4.02) or MIF-173 C allele carriers (GC + CC) (OR = 2.07, 95% CI: 1.21-3.55). An elevated risk of IM was found in subjects with MIF-173 CC genotype (OR = 2.27, 95% CI: 1.16-4.46) or MIF-173 C allele carriers (OR = 3.84, 95% CI: 1.58-9.34). The risk of SCAG and IM was more evident in subjects carrying IL-8-251 A allele (OR = 6.70, 95% CI: 1.29-9.78) or MIF-173 C allele (OR = 6.54, 95% CI: 2.97-14.20) and positive for H. pylori infection. CONCLUSION: IL-8-251 and MIF-173 gene polymorphisms are significantly associated with the risk of SCAG and IM in a population with a high risk of GC in Linqu County, Shandong Province, China.展开更多

Most gastric cancers develop through precancerous states of atrophic gastritis and intestinal metaplasia. Two staging systems, operative link for gastritis assessment(OLGA)and operative link on gastric intestinal metaplasia assessment(OLGIM), have been developed to detect high gastric cancer risk. European guidelines recommend surveillance for high-risk OLGA/OLGIM patients(stages Ⅲ–Ⅳ),and for those with advanced stage of atrophic gastritis in the whole stomach mucosa. We hypothesize, that by combining atrophy and intestinal metaplasia into one staging named TAIM, more patients with increased gastric cancer risk could be detected.AIM To evaluate the clinical value of the OLGA, OLGIM, and novel TAIM stagings as prognostic indicators for gastric cancer.METHODS In the Helsinki Gastritis Study, 22346 elderly male smokers from southwestern Finland were screened for serum pepsinogen I(PGI). Between the years 1989 and1993, men with low PGI values(PGI < 25 μg/L), were invited to undergo an oesophagogastroduodenoscopy. In this retrospective cohort study, 1147 men that underwent gastroscopy were followed for gastric cancer for a median of 13.7 years, and a maximum of 27.3 years. We developed a new staging system, TAIM,by combining the topography with the severity of atrophy or intestinal metaplasia in gastric biopsies. In TAIM staging, the gastric cancer risk is classified as low or high.RESULTS Twenty-eight gastric cancers were diagnosed during the follow-up, and the incidence rate was 1.72 per 1000 patient-years. The cancer risk associated positively with TAIM [Hazard ratio(HR) 2.70, 95%CI: 1.09–6.69, P = 0.03]. The risk increased through OLGIM stages 0-Ⅳ(0 vs Ⅳ: HR 5.72, 95%CI: 1.03–31.77, P for trend = 0.004), but not through OLGA stages 0–Ⅳ(0 vs Ⅳ: HR 5.77, 95%CI:0.67–49.77, P for trend = 0.10). The sensitivities of OLGA and OLGIM stages Ⅲ–Ⅳ were low, 21% and 32%, respectively, whereas that of TAIM high-risk was good, 79%. On the contrary, OLGA and OLGIM had high specificity, 85% and81%, respectively, but TAIM showed low specificity, 42%. In all three staging systems, the high-risk men had three-to four-times higher gastric cancer risk compared to the general male population of the same age.CONCLUSION OLGIM and TAIM stagings show prognostic value in assessing gastric cancer risk in elderly male smokers with atrophic gastritis.展开更多

文摘Gastric cystica profunda(GCP)is an uncommon but underestimated gastric lesion.Its precancerous potential determines its significance.In addition to previous mucosa injury due to operations,biopsy or polypectomy,chronic active and atrophic gastritis may also lead to the development of GCPs.By carefully examining the stomach and taking biopsy samples from the susceptible regions,the stage of atrophy can be determined.Chronic atrophic gastritis is a risk factor for cancer evolvement and it can also contribute to GCPs formation.GCPs frequently occur close to early gastric cancers(EGCs)or EGC can arise from the cystic glands.Endoscopic resection is an effective and minimally invasive treat-ment in GCP.

文摘[Objectives]To observe the effect of Jianpi Xiaowei Decoction on gastric function and quality of life in elderly patients with chronic atrophic gastritis(CAG)of liver-stomach heat stagnation type.[Methods]Seventy-two elderly patients with CAG of liver-stomach stagnation-heat type were randomly divided into study group and control group.The two groups were treated with Jianpi Xiaowei Decoction and Rabeprazole Enteric-coated Tablets respectively.The curative effect of TCM syndromes,serum pepsinogen I and II(PG-I and PG-II),gastrin-17(G-17)and quality of life(SF-36 table)scores of gastric function indicators before and after treatment were observed.[Results]After treatment,the total effective rate of the study group was 97.22%(35/36),which was significantly higher than that of the control group 77.78%(28/36)(P<0.05).Before treatment,there was no significant difference in the levels of gastric function indicators between the two groups(P>0.05).After treatment,the indicators of the study group were significantly lower than those of the control group(t=12.239,6.010,5.928,10.420,P<0.05).Before treatment,there was no significant difference in SF-36 scores between the two groups(P>0.05).After treatment,the SF-36 scores in the study group were significantly lower than those in the control group(t=3.520,10.335,11.300,9.693,P<0.05).[Conclusions]Jianpi Xiaowei Decoction can achieve significant curative effect in the treatment of CAG with liver and stomach stagnation heat type in the elderly,and can significantly improve the key gastrointestinal hormone levels and quality of life of elderly patients.It is worthy of promotion in the same clinical cases.
文摘BACKGROUND Helicobacter pylori(H.pylori)infection is closely related to the development of gastric cancer(GC).However,GC can develop even after H.pylori eradication.Therefore,it would be extremely useful if GC could be predicted after eradication.The Kyoto classification score for gastritis(GA)is closely related to cancer risk.However,how the score for GC changes after eradication before onset is not well understood.AIM To investigate the characteristics of the progression of Kyoto classification scores for GC after H.pylori eradication.METHODS Eradication of H.pylori was confirmed in all patients using either the urea breath test or the stool antigen test.The Kyoto classification score of GC patients was evaluated by endoscopy at the time of event onset and three years earlier.In ad-dition,the modified atrophy score was evaluated and compared between the GC group and the control GA group.RESULTS In total,30 cases of early GC and 30 cases of chronic GA were evaluated.The pathology of the cancer cases was differentiated adenocarcinoma,except for one case of undifferentiated adenocarcinoma.The total score of the Kyoto classifi-cation was significantly higher in the GC group both at the time of cancer onset and three years earlier(4.97 vs 3.73,P=0.0034;4.2 vs 3.1,P=0.0035,respectively).The modified atrophy score was significantly higher in the GC group both at the time of cancer onset and three years earlier and was significantly improved only in the GA group(5.3 vs 5.3,P=0.5;3.73 vs 3.1,P=0.0475,respectively).CONCLUSION The course of the modified atrophy score is useful for predicting the onset of GC after eradication.Patients with severe atrophy after H.pylori eradication require careful monitoring.
文摘BACKGROUND Autoimmune gastritis(AIG)is a progressive,chronic,immune-mediated inflammatory disease characterized by the destruction of gastric parietal cells leading to hypo/anacidity and loss of intrinsic factor.Gastrointestinal symptoms such as dyspepsia and early satiety are very common,being second in terms of frequency only to anemia,which is the most typical feature of AIG.AIM To address both well-established and more innovative information and knowledge about this challenging disorder.METHODS An extensive bibliographical search was performed in PubMed to identify guidelines and primary literature(retrospective and prospective studies,systematic reviews,case series)published in the last 10 years.RESULTS A total of 125 records were reviewed and 80 were defined as fulfilling the criteria.CONCLUSION AIG can cause a range of clinical manifestations,including dyspepsia.The pathophysiology of dyspepsia in AIG is complex and involves changes in acid secretion,gastric motility,hormone signaling,and gut microbiota,among other factors.Managing dyspeptic symptoms of AIG is challenging and there are no specific therapies targeting dyspepsia in AIG.While proton pump inhibitors are commonly used to treat dyspepsia and gastroesophageal reflux disease,they may not be appropriate for AIG.Prokinetic agents,antidepressant drugs,and non-pharmacological treatments may be of help,even if not adequately evidence-based supported.A multidisciplinary approach for the management of dyspepsia in AIG is recommended,and further research is needed to develop and validate more effective therapies for dyspepsia.
文摘BACKGROUND The incidence of type I gastric neuroendocrine neoplasms(gNENs)has increased significantly over the past 50 years.Although autoimmune gastritis(AIG)increases the likelihood of developing gNENs,the exact incidence and prevalence of this association remain unclear.AIM To evaluate the incidence and prevalence of type I gNENs in a cohort of patients with a histological diagnosis of AIG.METHODS Patients with a histological diagnosis of AIG were enrolled between October 2020 and May 2022.Circulating levels of CgA and gastrin were assessed at enrollment.Included patients underwent regular endoscopic follow-up to detect gastric neoplastic lesions,enterochromaffin-like(ECL)cell hyperplasia,and the development of gNEN.RESULTS We included 176 patients[142 women(80.7%),median age 64 years,interquartile range(IQR)53–71 years]diagnosed with AIG between January 1990 and June 2022.At enrollment.One hundred and sixteen patients(65.9%)had ECL hyperplasia,of whom,29.5%had simple/linear,30.7%had micronodular,and 5.7%had macronodular type.The median follow-up time was 5(3–7.5)years.After 1032 person-years,33 patients developed a total of 50 type I gNENs,with an incidence rate of 0.057 person-years,corresponding to an annual cumulative incidence of 5.7%.Circulating CgA levels did not significantly differ between AIG patients who developed gNENs and those who did not.Conversely,gastrin levels were significantly higher in AIG patients who developed gNENs[median 992 pg/mL IQR=449–1500 vs 688 pg/mL IQR=423–1200,P=0.03].Calculated gastrin sensitivity and specificity were 90.9%and 1.4%,respectively,with an overall diagnostic accuracy of 30%and a calculated area under the gastrin receiver operating characteristic curve(AUROC or AUC)of 0.53.CONCLUSION Type I gNENs are a significant complication in AIG.Gastrin’s low diagnostic accuracy prevents it from serving as a marker for early diagnosis.Effective strategies for early detection and treatment are needed.
文摘BACKGROUND Chronic atrophic gastritis is a persistent disorder of the digestive system where the gastric mucosa epithelium and glands undergo atrophy,leading to a decrease in their number and thinning of the gastric mucosa.It is worth noting that the prevalence of chronic atrophic gastritis is higher in China compared to the global average,and it is also considered a precancerous condition for gastric cancer.AIM To evaluate the efficacy of Huangqi Jianzhong decoction in treating chronic atrophic gastritis.Chronic atrophic gastritis is a persistent illness characterized by the progressive disappearance of healthy gastric glands due to repeated injury.Huangqi Jianzhong decoctions are widely used in China to treat chronic atrophic gastritis.However,there is limited scientific evidence regarding their efficacy in treating this illness.METHODS The present meta-analysis adhered to the PRISMA guidelines and used the Cochrane Collaboration methodology.We performed a comprehensive search for clinical trials investigating the use of Huangqi Jianzhong decoction in treating chronic atrophic gastritis published until January 2023.The risk of bias and the quality of the included studies were evaluated using the Cochrane Handbook guidelines.Finally,a meta-analysis was conducted using the RevMan 5.4 softRESULTS This study included a total of 13 articles,comprising 1269 samples.The meta-analysis was conducted on these 13 articles,yielding the following results:I2=0%,P=0.60,[RR=1.24,95%CI:1.18 to 1.30,P<0.00001].The forest plot analysis of the Helicobacter pylori clearance rate revealed I2=0%,P=0.36,[RR=1.20,95%CI:1.05 to 1.38,P=0.009].The forest plot of PG-I level showed I2=99%,P<0.00001,[MD=4.99,95%CI:-1.59 to 11.58,P=0.14].The forest plot of stomach pain demonstrated I2=54%,P=0.04,[MD=-0.63,95%CI:-0.68 to-0.58,P<0.00001].The forest plot of reflux indicated I2=82%,P=0.0009,[MD=-0.48,95%CI:-0.63 to-0.33,P<0.00001].The forest plot of recurrence rate exhibited I2=0%,P=0.92,[RR=0.15,95%CI:0.04 to 0.66,P=0.01].The forest plot of adverse reactions showed no heterogeneity in outcome data,[RR=1.07,95%CI:0.53 to 2.17,P=0.86].CONCLUSION This study demonstrated that Huangqi Jianzhong decoction improved various factors in adults with chronic atrophic gastritis.These factors included the total effective rate,Helicobacter pylori clearance rate,symptoms such as stomachache and acid reflux alleviation,and recurrence rates.
文摘BACKGROUND Mucosal patterns(MPs)observed on blue laser imaging in patients with atrophic gastritis can be classified as spotty,cracked,and mottled.Furthermore,we hypothesized that the spotty pattern may change to the cracked pattern after Helicobacter pylori(H.pylori)eradication.AIM To further substantiate and comprehensively investigate MP changes after H.pylori eradication in a larger number of patients.METHODS We included 768 patients who were diagnosed with atrophic gastritis with evaluable MP using upper gastrointestinal endoscopy at the Nishikawa Gastrointestinal Clinic,Japan.Among them,325 patients were H.pylori-positive,and of them,101 patients who underwent upper gastrointestinal endoscopy before and after H.pylori eradication were evaluated for post-eradication MP changes.The patients’MPs were interpreted by three experienced endoscopists who were blinded to their clinical features.RESULTS Among 76 patients with the spotty pattern before or after H.pylori eradication,the pattern disappeared or decreased in 67 patients[88.2%,95%confidence interval(CI):79.0%-93.6%),appeared or increased in 8 patients(10.5%,95%CI:5.4%-19.4%),and showed no change in 1 patient(1.3%,95%CI:0.2%-7.1%).In 90 patients with the cracked pattern before or after H.pylori eradication,the pattern disappeared or decreased in 7 patients(7.8%,95%CI:3.8%-15.2%),appeared or increased in 79 patients(87.8%,95%CI:79.4%-93.0%),and showed no change in 4 patients(4.4%,95%CI:1.7%-10.9%).In 70 patients with the mottled pattern before or after H.pylori eradication,the pattern disappeared or decreased in 28 patients(40.0%,95%CI:29.3%-51.7%),appeared or increased in 35 patients(50.0%,95%CI:38.6%-61.4%),and showed no change in 7 patients(10.0%,95%CI:4.9%-19.2%).CONCLUSION After H.pylori eradication,MPs changed from spotty to cracked in most patients,which may help endoscopists easily and precisely evaluate H.pylori-related gastritis status.

文摘AIM: To investigate the effects of interleukin-8 (IL-8 ), macrophage migration inhibitory factor (MIF ) gene polymorphisms, Helicobacter pylori (H. pylori ) infection, on the risk of developing severe chronic atrophic gastritis (SCAG) and intestinal metaplasia (IM). METHODS: A total of 372 cases were selected from a cohort study in Linqu County, a high risk area for gastric cancer (GC) in northern China. To obtain a sufficient group size, patients with normal or superficial gastritis were included. Based on an average follow-up period of 56 mo, the 372 cases were divided into no progres-sion group (no histological progression from normal or superficial gastritis, n = 137), group Ⅰ (progressed from normal or superficial gastritis to SCAG, n = 134) and group Ⅱ (progressed from normal or superficial gastritis to IM, n = 101). IL-8 , MIF gene polymorphisms were detected by polymerase chain reaction-based denaturing high-performance liquid chromatography analysis and DNA sequencing. RESULTS: An increased risk of SCAG was found in subjects with IL-8-251 AA genotype [odds ratio (OR) = 2.62, 95% CI: 1.23-5.72] or IL-8-251 A allele carriers (AA + AT) (OR = 1.81, 95% CI: 1.06-3.09). An elevated risk of IM was found in subjects with IL-8-251 AT genotype (OR = 2.27, 95% CI: 1.25-4.14) or IL-8-251 A allele carriers (OR = 2.07, 95% CI: 1.16-3.69). An increased risk of SCAG was found in subjects with MIF-173 GC genotype (OR = 2.36, 95% CI: 1.38-4.02) or MIF-173 C allele carriers (GC + CC) (OR = 2.07, 95% CI: 1.21-3.55). An elevated risk of IM was found in subjects with MIF-173 CC genotype (OR = 2.27, 95% CI: 1.16-4.46) or MIF-173 C allele carriers (OR = 3.84, 95% CI: 1.58-9.34). The risk of SCAG and IM was more evident in subjects carrying IL-8-251 A allele (OR = 6.70, 95% CI: 1.29-9.78) or MIF-173 C allele (OR = 6.54, 95% CI: 2.97-14.20) and positive for H. pylori infection. CONCLUSION: IL-8-251 and MIF-173 gene polymorphisms are significantly associated with the risk of SCAG and IM in a population with a high risk of GC in Linqu County, Shandong Province, China.
文摘BACKGROUND The pathological diagnosis and follow-up analysis of gastric mucosal biopsy have been paid much attention,and some scholars have proposed the pathological diagnosis of 12 kinds of lesions and accompanying pathological diagnosis,which is of great significance for the treatment of precision gastric diseases,the improvement of the early diagnosis rate of gastric cancer,and the reduction of missed diagnosis rate and misdiagnosis rate.AIM To perform a histopathological classification and follow-up analysis of chronic atrophic gastritis(CAG).METHODS A total of 2248 CAG tissue samples were collected,and data of their clinical characteristics were also gathered.Based on these samples,the expression levels of Mucin 1(MUC1),MUC2,MUC5AC,and MUC6 in CAG tissue were tested by immunohistochemical assay.Moreover,we followed these patients for up to four years.The difference between different stages of gastroscopic biopsy was observed.RESULTS Through observation,it is believed that CAG should be divided into four types,simple type,hyperplasia type,intestinal metaplasia(IM)type,and intraepithelial neoplasia(IEN)type.Simple CAG accounted for 9.1%(205/2248),which was more common in elderly people over 60 years old.The main change was that the lamina propria glands were reduced in size and number.Hyperplastic CAG accounted for 29.1%(654/2248),mostly occurring between 40 and 60 years old.The main change was that the lamina propria glands were atrophy accompanied by glandular hyperplasia and slight expansion of the glands.IM CAG accounted for 50.4%(1132/2248),most of which increased with age,and were more common in those over 50 years.The atrophy of the lamina propria glands was accompanied by significant IM,and the mucus containing sialic acid or sulfate was distinguished according to the nature of the mucus.The IEN type CAG accounted for 11.4%(257/2248),which developed from the previous types,with severe gland atrophy and reduced mucus secretion,and is an important precancerous lesion.CONCLUSION The histological typing of CAG is convenient to understand the property of lesion,determine the follow-up time,and guide the clinical treatment.
文摘BACKGROUND The risk of gastric cancer increases in patients with Helicobacter pylori-associated chronic atrophic gastritis(CAG).X-ray examination can evaluate the condition of the stomach,and it can be used for gastric cancer mass screening.However,skilled doctors for interpretation of X-ray examination are decreasing due to the diverse of inspections.AIM To evaluate the effectiveness of stomach regions that are automatically estimated by a deep learning-based model for CAG detection.METHODS We used 815 gastric X-ray images(GXIs)obtained from 815 subjects.The ground truth of this study was the diagnostic results in X-ray and endoscopic examinations.For a part of GXIs for training,the stomach regions are manually annotated.A model for automatic estimation of the stomach regions is trained with the GXIs.For the rest of them,the stomach regions are automatically estimated.Finally,a model for automatic CAG detection is trained with all GXIs for training.RESULTS In the case that the stomach regions were manually annotated for only 10 GXIs and 30 GXIs,the harmonic mean of sensitivity and specificity of CAG detection were 0.955±0.002 and 0.963±0.004,respectively.CONCLUSION By estimating stomach regions automatically,our method contributes to the reduction of the workload of manual annotation and the accurate detection of the CAG.
文摘BACKGROUND Gastric cancer is the world’s third most lethal malignancy. Most gastric cancers develop through precancerous states of atrophic gastritis and intestinal metaplasia. Two staging systems, operative link for gastritis assessment(OLGA)and operative link on gastric intestinal metaplasia assessment(OLGIM), have been developed to detect high gastric cancer risk. European guidelines recommend surveillance for high-risk OLGA/OLGIM patients(stages Ⅲ–Ⅳ),and for those with advanced stage of atrophic gastritis in the whole stomach mucosa. We hypothesize, that by combining atrophy and intestinal metaplasia into one staging named TAIM, more patients with increased gastric cancer risk could be detected.AIM To evaluate the clinical value of the OLGA, OLGIM, and novel TAIM stagings as prognostic indicators for gastric cancer.METHODS In the Helsinki Gastritis Study, 22346 elderly male smokers from southwestern Finland were screened for serum pepsinogen I(PGI). Between the years 1989 and1993, men with low PGI values(PGI < 25 μg/L), were invited to undergo an oesophagogastroduodenoscopy. In this retrospective cohort study, 1147 men that underwent gastroscopy were followed for gastric cancer for a median of 13.7 years, and a maximum of 27.3 years. We developed a new staging system, TAIM,by combining the topography with the severity of atrophy or intestinal metaplasia in gastric biopsies. In TAIM staging, the gastric cancer risk is classified as low or high.RESULTS Twenty-eight gastric cancers were diagnosed during the follow-up, and the incidence rate was 1.72 per 1000 patient-years. The cancer risk associated positively with TAIM [Hazard ratio(HR) 2.70, 95%CI: 1.09–6.69, P = 0.03]. The risk increased through OLGIM stages 0-Ⅳ(0 vs Ⅳ: HR 5.72, 95%CI: 1.03–31.77, P for trend = 0.004), but not through OLGA stages 0–Ⅳ(0 vs Ⅳ: HR 5.77, 95%CI:0.67–49.77, P for trend = 0.10). The sensitivities of OLGA and OLGIM stages Ⅲ–Ⅳ were low, 21% and 32%, respectively, whereas that of TAIM high-risk was good, 79%. On the contrary, OLGA and OLGIM had high specificity, 85% and81%, respectively, but TAIM showed low specificity, 42%. In all three staging systems, the high-risk men had three-to four-times higher gastric cancer risk compared to the general male population of the same age.CONCLUSION OLGIM and TAIM stagings show prognostic value in assessing gastric cancer risk in elderly male smokers with atrophic gastritis.
