| 1 | Clinicopathologic factors and molecular markers related to lymph node metastasis in early gastric cancer显示文摘AIM: To analyze predictive factors for lymph node metastasis in early gastric cancer.METHODS: We analyzed 1104 patients with early gastric cancer(EGC) who underwent a gastrectomy with lymph-node dissection from May 2003 through July 2011. The clinicopathologic factors and molecular markers were assessed as predictors for lymph node metastasis. Molecular markers such as microsatellite instability, human mut L homolog 1, p53, epidermal growth factor receptor(EGFR) and human epidermal growth factor receptor 2(HER2) were included. The χ2 test and logistic regression analysis were used to determine clinicopathologic parameters.RESULTS: Lymph node metastasis was observed in 104(9.4%) of 1104 patients. Among 104 cases of lymph node positive patients, 24 patients(3.8%) were mucosal cancers and 80 patients(16.7%) were submucosal. According to histologic evaluation, the number of lymph node metastasis found was 4(1.7%) for well differentiated tubular adenocarcinoma, 45(11.3%) for moderately differentiated tubular adenocarcinoma, 36(14.8%) for poorly differentiated tubular adenocarcinoma, and 19(8.4%) for signet ring cell carcinoma. Of 690 EGC cases, 77 cases(11.2%) showed EGFR overexpression. HER2 overexpression was present in 110 cases(27.1%) of 406 EGC patients. With multivariate analysis, female gender(OR = 2.281, P = 0.009), presence of lymphovascular invasion(OR = 10.950, P < 0.0001), diameter(≥ 20 mm, OR = 3.173, P = 0.01), and EGFR overexpression(OR = 2.185, P = 0.044) were independent risk factors for lymph node involvement.CONCLUSION: Female gender, tumor size, lymphovascular invasion and EGFR overexpression were predictive risk factors for lymph node metastasis in EGC. | Eun Hyo Jin Dong Ho Lee Sung-Ae Jung Ki-Nam Shim Ji Yeon Seo Nayoung Kim Cheol Min Shin Hyuk Yoon Hyun Chae Jung | 2015 | World Journal of Gastroenterology2015，21，2： | 30 |
| 2 | Characteristics of gastric cancer in peptic ulcer patients with Helicobacter pylori infection显示文摘AIM:To evaluate the incidence and clinical characteristics of gastric cancer(GC) in peptic ulcer patients with Helicobacter pylori(H.pylori) infection.METHODS:Between January 2003 and December 2013, the medical records of patients diagnosed with GC were retrospectively reviewed.Those with previous gastric ulcer(GU) and H.pylori infection were assigned to the Hp GU-GC group(n = 86) and those with previous duodenal ulcer(DU) disease and H.pylori infection were assigned to the Hp DUGC group(n = 35).The incidence rates of GC in the Hp GU-GC and Hp DU-GC groups were analyzed.Data on demographics(age, gender, peptic ulcer complications and cancer treatment), GC clinical characteristics [location, pathological diagnosis, differentiation, T stage, Lauren's classification, atrophy of surrounding mucosa and intestinal metaplasia(IM)], outcome of eradication therapy for H.pylori infection, esophagogastroduodenoscopy number and the duration until GC onset were reviewed.Univariate and multivariate analyses were performed to identify factors influencing GC development.The relative risk of GC was evaluated using a Cox proportional hazards model.RESULTS:The incidence rates of GC were 3.60%(86/2387) in the Hp GU-GC group and 1.66%(35/2098) in the Hp DU-GC group.The annual incidence was 0.41% in the Hp GU-GC group and 0.11% in the Hp DUGC group.The rates of moderate-to-severe atrophy of the surrounding mucosa and IM were higher in the Hp GU-GC group than in the Hp DU-GC group(86% vs 34.3%, respectively, and 61.6% vs 14.3%, respectively, P < 0.05).In the univariate analysis, atrophy of surrounding mucosa, IM and eradication therapy for H.pylori infection were significantly associated with the development of GC(P < 0.05).There was no significant difference in the prognosis of GC patients between the Hp GU-GC and Hp DU-GC groups(P = 0.347).The relative risk of GC development in the Hp GUGC group compared to that of the Hp DU-GC group,after correction for age and gender,was 1.71(95%CI:1.09-2.70;P=0.02).CONCLUSION:GU patients with H.pylori infection had higher GC incidence rates and relative risks.Atrophy of surrounding mucosa,IM and eradication therapy were associated with GC. | Jae Jin Hwang Dong Ho Lee Ae-Ra Lee Hyuk Yoon Cheol Min Shin Young Soo Park Nayoung Kim | 2015 | World Journal of Gastroenterology2015，21，16： | 15 |

| 4 | Differentiation of hepatocellular carcinoma from its variousmimickers in liver magnetic resonance imaging:What arethe tips when using hepatocyte-specific agents?显示文摘Hepatocellular carcinoma is the most common primary hepatic malignant tumor.With widespread use of liver imaging,various cirrhosis-related nodules are frequently detected in patients with chronic liver disease,while diverse hypervascular hepatic lesions are incidentally detected but undiagnosed on dynamic computed tomography and magnetic resonance imaging(MRI).However,use of hepatocyte-specific MR contrast agents with combined perfusion and hepatocyte-selective properties have improved diagnostic performance in detection and characterization of focal liver lesions.Meanwhile,the enhancement patterns observed during dynamic phases using hepatocyte-specific agents may be different from those observed during MRI using conventional extracellular fluid agents,leading to confusion in diagnosis.Therefore,we discuss useful tips for the differentiation of hepatocellular carcinoma from similar lesions in patients with and without chronic liver disease using liver MRI with hepatocyte-specific agents. | Yang Shin Park Chang Hee Lee Jeong Woo Kim Sora Shin Cheol Min Park | 2016 | World Journal of Gastroenterology2016，22，1： | 10 |
| 5 | Clinical and endoscopic characteristics of drug-induced esophagitis显示文摘AIM: To investigate clinical, endoscopic and pathological characteristics of drug-induced esophagitis.METHODS: Data for patients diagnosed with drug-induced esophagitis from April 2002 to May 2013 was reviewed. Patients diagnosed with malignancy, viral or fungal esophagitis were excluded. Clinical, endoscopic and pathological characteristics of patients diagnosed with drug-induced esophagitis were analyzed.RESULTS: Seventy-eight patients were diagnosed with drug-induced esophagitis. Their mean age was 43.9 ± 18.9 years and 35.9% were male. Common symptoms were chest pain(71.8%), odynophagia(38.5%) and dysphagia(29.5%). The endoscopic location was in the middle third of esophagus in 78.2%. Endoscopic findings were ulcer(82.1%), erosion(17.9%), ulcer with bleeding(24.4%), coating with drug material(5.1%), impacted pill fragments(3.8%) and stricture(2.6%). Kissing ulcers were observed in 43.6%. The main causative agents were antibiotics and non-steroidal antiinflammatory drugs. All the patients were treated with proton pump inhibitors(PPIs) or sucralfate, and the causative drugs were discontinued. Nineteen patients with drug-induced esophagitis were followed up with endoscopy and revealed normal findings, scars or healing ulcers.CONCLUSION: Drug-induced esophagitis mainly presents as chest pain, odynophagia and dysphagia, and may be successfully treated with PPIs and discontinuation of the causative drug. Kissing ulcers were observed in 43.6%. | Su Hwan Kim Ji Bong Jeong Ji Won Kim Seong-Joon Koh Byeong Gwan Kim Kook Lae Lee Mee Soo Chang Jong Pil Im Hyoun Woo Kang Cheol Min Shin | 2014 | World Journal of Gastroenterology2014，20，31： | 7 |
| 6 | Optimal initiation of Helicobacter pylori eradication in patients with peptic ulcer bleeding显示文摘AIM:To evaluate when Helicobacter pylori(H.pylori)eradication therapy(ET)should be started in patients with peptic ulcer bleeding(PUB).METHODS:Clinical data concerning adults hospitalizedwith PUB were retrospectively collected and analyzed.Age,sex,type and stage of peptic ulcer,whether endoscopic therapy was performed or not,methods of H.pylori detection,duration of hospitalization,and specialty of the attending physician were investigated.Factors influencing the confirmation of H.pylori infection prior to discharge were determined using multiple logistic regression analysis.The H.pylori eradication rates of patients who received ET during hospitalization and those who commenced ET as outpatients were compared.RESULTS:A total of 232 patients with PUB were evaluated for H.pylori infection by histology and/or rapid urease testing.Of these patients,53.7%(127/232)had confirmed results of H.pylori infection prior to discharge.In multivariate analysis,duration of hospitalization and ulcer stage were factors independently influencing whether H.pylori infection was confirmed before or after discharge.Among the patients discharged before confirmation of H.pylori infection,13.3%(14/105)were lost to follow-up.Among the patients found to be H.pylori-positive after discharge,41.4%(12/29)did not receive ET.There was no significant difference in the H.pylori eradication rate between patients who received ET during hospitalization a n d t h o s e w h o c o m m e n c e d E T a s o u t p a t i e n t s[intention-to-treat:68.8%(53/77)vs 60%(12/20),P=0.594;per-protocol:82.8%(53/64)vs 80%(12/15),P=0.723].CONCLUSION:Because many patients with PUB who were discharged before H.pylori infection status was confirmed lost an opportunity to receive ET,we should confirm H.pylori infection and start ET prior to discharge. | Hyuk Yoon Dong Ho Lee Eun Sun Jang Jaihwan Kim Cheol Min Shin Young Soo Park Jin-Hyeok Hwang Jin-Wook Kim Sook-Hayng Jeong Nayoung Kim | 2015 | World Journal of Gastroenterology2015，21，8： | 7 |
| 7 | Clinicopathologic and molecular features associated with patient age in gastric cancer显示文摘AIM: To compare characteristics and prognosis of gastric cancer based on age.METHODS: A retrospective study was conducted on clinical and molecular data from patients(n =1658) with confirmed cases of gastric cancer in Seoul National University Bundang Hospital(Seoul, South Korea) from 2003 to 2010 after exclusion of patients diagnosed with lymphoma, gastrointestinal stromal tumor, and metastatic cancer in the stomach. DNA was isolated from tumor and adjacent normal tissue,and a set of five markers was amplified by polymerase chain reaction to assess microsatellite instability(MSI). MSI was categorized as high, low, or stable if ≥ 2, 1, or 0 markers, respectively, had changed.Immunohistochemistry was performed on tissue sections to detect levels of expression of p53, human epidermal growth factor receptor(HER)-2, and epidermal growth factor receptor. Statistical analysis of clinical and molecular data was performed to assess prognosis based on the stratification of patients by age(≤ 45 and> 45 years).RESULTS: Among the 1658 gastric cancer patients, the number of patients with an age ≤ 45 years was 202(12.2%; 38.9 ± 0.4 years) and the number of patients> 45 years was 1456(87.8%; 64.1 ± 0.3 years).Analyses revealed that females were predominant inthe younger group(P < 0.001). Gastric cancers in the younger patients exhibited more aggressive features and were at a more advanced stage than those in older patients. Precancerous lesions, such as atrophic gastritis and intestinal metaplasia, were observed less frequently in the older than in the younger group(P < 0.001). Molecular characteristics, including overexpression of p53(P < 0.001), overexpression of HER-2(P = 0.006), and MSI(P = 0.006), were less frequent in gastric cancer of younger patients. Cancer related mortality was higher in younger patients(P= 0.048), but this difference was not significant after adjusting for the stage of cancer.CONCLUSION: Gastric cancer is distinguishable between younger and older patients based on both clinicopathologic and molecular features, but stage is the most important predictor of prognosis. | Ji Yeon Seo Eun Hyo Jin Hyun Jin Jo Hyuk Yoon Cheol Min Shin Young Soo Park Nayoung Kim Hyun Chae Jung Dong Ho Lee | 2015 | World Journal of Gastroenterology2015，21，22： | 7 |
| 8 | Eradication rate and histological changes after Helicobacter pylori eradication treatment in gastric cancer patients following subtotal gastrectomy显示文摘AIM: To investigate the eradication rate and histological changes after Helicobacter pylori(H. pylori) eradication treatment following subtotal gastrectomy for gastric cancer.METHODS: A total of 610 patients with H. pylori infection who had undergone surgery for either early or advanced gastric adenocarcinoma between May 2004 and December 2010 were retrospectively studied. A total of 584 patients with proven H. pylori infection after surgery for gastric cancer were enrolled in this study. Patients received a seven day standard triple regimen as first-line therapy and a 10 d bismuthcontaining quadruple regimen as second-line therapy in cases of eradication failure. The patients underwent an esophagogastroduodenoscopy(EGD) between six and 12 mo after surgery, followed by annual EGDs. A further EGD was conducted 12 mo after confirming the result of the eradication and the histological changes. A gastric biopsy specimen for histological examination and Campylobacter-like organism testing was obtained from the lesser and greater curvature of the corpus of the remnant stomach. Histological changes in the gastric mucosa were assessed using the updated Sydney system before eradication therapy and at follow-up after 12 mo.RESULTS: Eradication rates with the first-line and second-line therapies were 78.4%(458/584) and 90%(36/40), respectively, by intention-to-treat analysis and 85.3%(458/530) and 92.3%(36/39), respectively, by per-protocol analysis. The univariate and multivariate analyses revealed that Billroth Ⅱ surgery was an independent factor predictive of eradication success in the eradication success group(OR = 1.53, 95%CI: 1.41-1.65, P = 0.021). The atrophy and intestinal metaplasia(IM) scores 12 mo after eradication were significantly lower in the eradication success group than in the eradication failure group(0.25 ± 0.04 vs 0.47 ± 0.12, P = 0.023; 0.27 ± 0.04 vs 0.51 ± 0.12, P = 0.015, respectively). The atrophy and IM scores 12 mo after successful eradication were significantly lower in the Billroth Ⅱ group than in the Billroth I group(0.13 ± 0.09 vs 0.31 ± 0.12, P = 0.029; 0.32 ± 0.24 vs 0.37 ± 0.13, P = 0.034, respectively).CONCLUSION: Patients with H. pylori following subtotal gastrectomy had a similar eradication rate to patients with an intact stomach. H. pylori eradication is recommended after subtotal gastrectomy. | Jae Jin Hwang Dong Ho Lee Kyu Keun Kang Ae-Ra Lee Hyuk Yoon Cheol Min Shin Young Soo Park Nayoung Kim | 2015 | World Journal of Gastroenterology2015，21，13： | 5 |

| 12 | Fourteen- vs seven-day bismuth-based quadruple therapy for second-line Helicobacter pylori eradication显示文摘AIM: To compare the efficacy of 14- and 7-d bismuthbased quadruple therapies as second-line eradication treatment for Helicobacter pylori(H.pylori) infection.METHODS: Between 2004 and 2014,the medical records of 790 patients who had experienced failure of first-line proton pump inhibitor(PPI)-based eradication therapy and were then treated with bismuth-based quadruple therapy were retrospectively reviewed.Those who received bismuth-based quadruple therapy [PPI,bismuth,metronidazole,and tetracycline(PBMT)] for either 7 d or 14 d were assigned to a PBMT-7 group(n = 543) or a PBMT-14 group(n = 247),respectively.The eradication rates for both groups were determined by intention-to-treat(ITT) and per-protocol(PP) analyses.ITT analysis compared the treatment groups as originally allocated while the PP analysis including only those patients who had completed the treatment as originally allocated.Successful eradication therapy for H.pylori infection was defined as a negative 13C-urea breath test 4 wk after the end of eradication treatment.RESULTS: The overall ITT eradication rate was 69.1%(546/790).Final ITT eradication rates were 67.4%(366/543; 95%CI: 63.1%-71.7%) in the PBMT-7 group and 72.8%(180/247; 95%CI: 67.4%-78.2%) in the PBMT-14 group(P = 0.028).The overall PP eradication rate was 80.0%(546/682),and the final PP eradication rates were 78.2%(366/468; 95%CI: 72.1%-84.0%) in the PBMT-7 group and 84.1%(180/214; 95%CI: 76.8%-90.8%) in the PBMT-14 group(P = 0.009).The H.pylori eradication rates in the PBMT-14 group weresignificantly higher than in the PBMT-7 group according to both ITT(P = 0.028) and PP analysis(P = 0.009).Compliance was similar in both groups(PBMT-7 group: 97.9%; PBMT-14 group: 96.4%).Adverse event rates were 10.7%(51/478) and 17.1%(38/222) in the PBMT-7 and PBMT-14 groups,respectively(P = 0.487).CONCLUSION: The 14-d bismuth-based quadruple therapy is a significantly more effective second-line eradication treatment for H.pylori infection than the 7-d alternative. | Jae Jin Hwang Dong Ho Lee Ae-Ra Lee Hyuk Yoon Cheol Min Shin Young Soo Park Nayoung Kim | 2015 | World Journal of Gastroenterology2015，21，26： | 3 |
| 13 | Efficacy of moxifloxacin-based sequential and hybrid therapy for first-line Helicobacter pylori eradication显示文摘AIM: To evaluate the efficacy of moxifloxacin-based sequential therapy(MBST) versus hybrid therapy as a first-line treatment for Helicobacter pylori(H. pylori) infection.METHODS: From August 2014 to January 2015, 284 patients with confirmed H. pylori infection were randomized to receive a 14-d course of MBST(MBST group, n = 140) or hybrid(Hybrid group, n = 144) therapy. The MBST group received 20 mg rabeprazole and 1 g amoxicillin twice daily for 7 d, followed by 20 mg rabeprazole and 500 mg metronidazole twice daily, and 400 mg moxifloxacin once daily for 7 d. The Hybrid group received 20 mg rabeprazole and 1 g amoxicillin twice daily for 14 d. In addition, the Hybrid group received 500 mg metronidazole and 500 mg clarithromycin twice daily for the final 7 d. Successful eradication of H. pylori infection was defined as a negative 13C-urea breath test 4 wk after the end of treatment. Patient compliance was defined as 'good' if drug intake was at least 85%. H. pylori eradication rates, patient compliance with treatment, and adverse event rates were evaluated.RESULTS: The eradication rates in the intention-totreat(ITT) analysis were 91.4%(128/140; 95%CI: 90.2%-92.9%) in the MBST group and 79.2%(114/144; 95%CI: 77.3%-80.7%) in the Hybrid group(P = 0.013). The eradication rates in the perprotocol(PP) analysis were 94.1%(128/136; 95%CI: 92.9%-95.6%) in the MBST group and 82.6%(114/138; 95%CI: 80.6%-84.1%) in the Hybrid group(P = 0.003). The H. pylori eradication rate in the MBST group was significantly higher than that of the Hybrid group for both the ITT(P = 0.013) and the PP analyses(P = 0.003). Both groups exhibited full compliance with treatment(MBST/Hybrid group: 100%/100%). The rate of adverse events was 11.8%(16/136) and 19.6%(27/138) in the MBST and Hybrid group, respectively(P = 0.019). The majority of adverse events were mild-to-moderate in intensity; none were severe enough to cause discontinuation of treatment in either group.CONCLUSION: MBST was more effective and led to fewer adverse events than hybrid therapy as a first-line treatment for H. pylori infection. | Jae Jin Hwang Dong Ho Lee Ae-Ra Lee Hyuk Yoon Cheol Min Shin Young Soo Park Nayoung Kim | 2015 | World Journal of Gastroenterology2015，21，35： | 3 |
| 14 | Moxifloxacin-containing triple therapy after non-bismuth quadruple therapy failure for Helicobacter pylori infection显示文摘AIM: To assess the efficacy of moxifloxacin-containing triple therapy after non-bismuth quadruple therapy failure for Helicobacter pylori(H. pylori) eradication.METHODS: Between January 2010 and December 2012,we screened individuals who were prescribed non-bismuth quadruple therapy for H. pylori eradication. Among them,a total of 98 patients who failed non-bismuth quadruple therapy received 1-wk or 2-wk moxifloxacin-containing triple therapy(400 mg moxifloxacin once daily,and 20 mg of rabeprazole and 1 g of amoxicillin twice daily). H. pylori status was evaluated using the 13C-urea breath test 4 wk later,after treatment completion. The eradication rates were determined by intention-to-treat and per-protocol analyses.RESULTS: In total,60 and 38 patients received 1-wk and 2-wk moxifloxacin-containing triple therapy,respectively. The intention-to-treat and per-protocol eradication rates were 56.7%(95%CI: 45.0-70.0) and 59.6%(95%CI: 46.6-71.7) in the 1-wk group and 76.3%(95%CI: 63.2-89.5) and 80.6%(95%CI: 66.7-91.9) in the 2-wk group(P = 0.048 and 0.036,respectively). All groups had good compliance(95% vs 94.9%). Neither group showed serious adverse events,and the proportions of patients experiencing mild side effects were not significantly different(21.1% vs 13.9%). Clinical factors such as age,sex,alcohol and smoking habits,comorbidities,and presence of gastric or duodenal ulcer did not influence the eradication therapy efficacy. The efficacy of second-line eradication therapy did not differ significantly according to the firstline regimen.CONCLUSION: Two-week moxifloxacin-containing triple therapy showed better efficacy than a 1-wk regimen after non-bismuth quadruple therapy failure.Key words: Helicobacter pylori; Moxifloxacin-based triple; Non-bismuth quadruple; Second-line; | Ji Hyun Lim Dong Ho Lee Seong Tae Lee Nayoung Kim Young Soo Park Cheol Min Shin In Sung Song | 2015 | World Journal of Gastroenterology2015，21，46： | 2 |
| 15 | Efficacy of 14-d vs 7-d moxifloxacin-based triple regimens for second-line Helicobacter pylori eradication显示文摘AIM: To evaluate the efficacy of the 14-d moxifloxacinbased triple therapy for the second-line eradication of Helicobacter pylori(H. pylori) infection.METHODS: Between 2011 and 2013, we conducted a retrospective review of the medical records of 160 patients who had experienced failure of their first-line proton pump inhibitor-based eradication therapy and subsequently received the moxifloxacin-based triple therapy as a second-line eradication treatment regimen. The patients who were treated with the moxifloxacinbased triple therapy(oral 20 mg rabeprazole b.i.d., 1000 mg amoxicillin b.i.d., and 400 mg moxifloxacin q.d.) for 7 d were assigned to the RAM-7 group(n = 79) while those who took them for 14 days were assigned to RAM-14 group(n = 81). The eradication rates for both groups were determined by intentionto-treat(ITT) and per-protocol(PP) analyses. ITT analysis compared the treatment groups as originally allocated while the PP analysis including only those patients who had completed the treatment as originally allocated. Successful eradication therapy for H. pylori infection was defined as the documentation of a negative 13C-urea breath test 4 wk after the end of the eradication treatment.RESULTS: The overall ITT eradication rate was 76.2%(122/160). The final ITT eradication rates were 70.8%(56/79; 95%CI: 63.3%-77.1%) in the RAM-7 group and 81.4%(66/81; 95%CI: 74.6%-88.3%) in the RAM-14 group(P = 0.034). The overall PP eradication rate was 84.1%(122/145), and the final PP eradication rates were 77.7%(56/72; 95%CI: 70.2%-85.3%) in the RAM-7 group and 90.4%(66/73; 95%CI: 82.8%-98.1%) in the RAM-14 group(P = 0.017). The H. pylori-eradication rates in the RAM-14 group were significantly higher compared with that of the RAM-7 group according to both the ITT(P = 0.034) and the PP analyses(P = 0.017). Both groups exhibited good treatment compliance(RAM-7/RAM-14 group: 100%/100%). The adverse event rates were19.4%(14/72)and 20.5%(15/73)in the RAM-7 and RAM-14 groups,respectively(P=0.441).Adverse events occurred in 14 of the 72 patients(19.4)in the RAM-7 group and in 15 of the 73 patients(20.5)in the RAM-14 group.No statistically significant differences(P=0.441)were observed.CONCLUSION:The 14-d moxifloxacin-based triple therapy is a significantly more effective secondline eradication treatment as compared to the 7-d alternative for H.pylori infection in South Korea. | Jae Jin Hwang Dong Ho Lee Ae-Ra Lee Hyuk Yoon Cheol Min Shin Young Soo Park Nayoung Kim | 2015 | World Journal of Gastroenterology2015，21，18： | 2 |

| 18 | Sex-based differences in histology,staging,and prognosis among 2983 gastric cancer surgery patients显示文摘BACKGROUND Few studies have been conducted on sex differences in the incidence, pathophysiology, and prognosis of gastric cancer(GC).AIM To analyze the differences in GC characteristics according to sex in patients who underwent surgical treatment for GC.METHODS A total of 2983 patients diagnosed with gastric adenocarcinoma who received surgical treatment at the Seoul National University Bundang Hospital between 2003 and 2017 were included.Baseline clinicopathological characteristics, histologic type of GC, overall and GC-specific survival rates, and associated risk factors were analyzed.RESULTS Among the 2983 patients, 2005(67.2%) and 978(32.8%) were males and females, respectively.The average age of the female group(59.36 years) was significantly younger than that of the male group(61.66 years;P < 0.001).Cancer of the gastric body(P < 0.001) and diffuse-type histology(P < 0.001) were more common in females than in males.This trend was more prominent in females younger than 60 years of age, with a significantly higher proportion of diffuse-type cancer than in the male group.Regardless of sex, diffuse-type GC was more common in younger patients, and the proportion of intestinal-type GC increased with age.The overall survival rate was significantly higher in females(P < 0.001).However, this difference disappeared for GC-specific survival(P = 0.168), except for the poor GC-specific survival rate in advanced-stage cancer(stage Ⅲ or above) in females(P = 0.045).The risk factors for GC-related mortality were older age, upper location of GC, and diffuse-or mixed-type histology.In terms of comorbidities, more males died from diseases other than GC, including other malignancies such as lung cancer, hepatocellular carcinoma, and pancreatic cancer, and respiratory diseases such as interstitial lung disease and chronic obstructive pulmonary disease, while there were relatively more cardiovascular or cerebrovascular deaths in females.CONCLUSION Sex-based differences in GC were observed in clinicopathological features, including age at diagnosis, tumor location, histologic type, survival rate, and comorbidities. | Yonghoon Choi Nayoung Kim Ki Wook Kim Hyeong Ho Jo Jaehyung Park Hyuk Yoon Cheol Min Shin Young Soo Park Dong Ho Lee Hyeon Jeong Oh Hye Seung Lee Young Suk Park Sang-Hoon Ahn Yun-Suhk Suh Do Joong Park Hyung-Ho Kim Ji-Won Kim Jin Won Kim Keun-Wook Lee Won Chang Ji HoonPark Yoon Jin Lee Kyoung Ho Lee Young Hoon Kim | 2022 | World Journal of Gastroenterology2022，28，9： | 2 |
