| 1 | Survival outcome of patients with spontaneously ruptured hepatocellular carcinoma treated surgically or by transarterial embolization显示文摘AIM: To evaluate clinical outcomes of patients that underwent surgery, transarterial embolization (TAE), or supportive care for spontaneously ruptured hepatocellular carcinoma (HCC). METHODS: A consecutive 54 patients who diagnosed as spontaneously ruptured HCC at our institution between 2003 and 2012 were retrospectively enrolled. HCC was diagnosed based on the diagnostic guidelines issued by the 2005 American Association for the Study of Liver Diseases. HCC rupture was defined as disruption of the peritumoral liver capsule with enhanced fluid collection in the perihepatic area adjacent to the HCC by dynamic liver computed tomography, and when abdominal paracentesis showed an ascitic red blood cell count of > 50000 mm 3 /mL in bloody fluid. RESULTS: Of the 54 patients, 6 (11.1%) underwent surgery, 25 (46.3%) TAE, and 23 (42.6%) supportive care. The 2-, 4and 6-mo cumulative survival rates at 2, 4 and 6 mo were significantly higher in the surgery (60%, 60% and 60%) or TAE (36%, 20% and 20%) groups than in the supportive care group (8.7%, 0% and 0%), respectively (each, P < 0.01), and tended to be higher in the surgical group than in the TAE group. Multivariate analysis showed that serum bilirubin (HR = 1.09, P < 0.01), creatinine (HR = 1.46, P = 0.04), and vasopressor requirement (HR = 2.37, P = 0.02) were significantly associated with post-treatment mortality, whereas surgery (HR = 0.41, P < 0.01), and TAE (HR = 0.13, P = 0.01) were inversely associated with posttreatment mortality. CONCLUSION: Post-treatment survival after surgery or TAE was found to be better than after supportive care, and surgery tended to provide better survival benefit than TAE. | Young-Joo Jin Jin-Woo Lee Seoung-Wook Park Jung Il Lee Don Haeng Lee Young Soo Kim Soon Gu Cho Yong Sun Jeon Kun Young Lee Seung-Ik Ahn | 2013 | World Journal of Gastroenterology2013，19，28： | 23 |

| 3 | Alcoholic liver disease: Treatment显示文摘The excess consumption of alcohol is associated with alcoholic liver diseases(ALD). ALD is a major healthcare problem, personal and social burden, and significant reason for economic loss worldwide. The ALD spectrum includes alcoholic fatty liver, alcoholic hepatitis, cirrhosis, and the development of hepatocellular carcinoma. The diagnosis of ALD is based on a combination of clinical features, including a history of significant alcohol intake, evidence of liver disease, and laboratory findings. Abstinence is the most important treatment for ALD and the treatment plan varies according to the stage of the disease. Various treatments including abstinence, nutritional therapy, pharmacological therapy, psychotherapy, and surgery are currently available. For severe alcoholic hepatitis, corticosteroid or pentoxifylline are recommended based on the guidelines. In addition, new therapeutic targets are being under investigation. | Ki Tae Suk Moon Young Kim Soon Koo Baik | 2014 | World Journal of Gastroenterology2014，20，36： | 20 |
| 4 | Overexpression of the M2 isoform of pyruvate kinase is an adverse prognostic factor for signet ring cell gastric cancer显示文摘AIM:To investigate M2 isoform of pyruvate kinase(PKM2) expression in gastric cancers and evaluate its potential as a prognostic biomarker and an anticancer target.METHODS:All tissue samples were derived from gastric cancer patients underwent curative gastrectomy as a primary treatment.Clinical and pathological information were obtained from the medical records.Gene expression microarray data from 60 cancer and 19 noncancer gastric tissues were analyzed to evaluate the expression level of PKM2 mRNA.Tissue microarrays were constructed from 368 gastric cancer patients.Immunohistochemistry was used to measure PKM2 expression and PKM2 positivity of cancer was determined by proportion of PKM2-positive tumor cells and staining intensity.Association between PKM2 expression and the clinicopathological factors was evaluated and the correlation between PKM2 and cancer prognosis was evaluated.RESULTS:PKM2 mRNA levels were increased more than 2-fold in primary gastric cancers compared to adjacent normal tissues from the same patients(log transformed expression level:7.6 ± 0.65 vs 6.3 ± 0.51,P < 0.001).Moreover,differentiated type cancers had significantly higher PKM2 mRNA compared to undifferentiated type cancers(log transformed expression level:7.8 ± 0.70 vs 6.7 ± 0.71,P < 0.001).PKM2 protein was mainly localized in the cytoplasm of primary cancer cells and detected in 144 of 368(39.1%) human gastric cancer cases.PKM2 expression was not related with stage(P = 0.811),but strongly correlated with gastric cancer differentiation(P < 0.001).Differentiated type cancers expressed more PKM2 protein than did the undifferentiated ones.Well differentiated adenocarcinoma showed 63.6% PKM2-positive cells;in contrast,signet-ring cell cancers showed only 17.7% PKM2-positive cells.Importantly,PKM2 expression was correlated with shorter overall survival(P < 0.05) independent of stage only in signet-ring cell cancers.CONCLUSION:PKM2 expression might be an adverse prognostic factor for signet-ring cell carcinomas.Its function and potential as a prognostic marker should be further verified in gastric cancer. | Jae Yun Lim Sun Och Yoon So Young Seol Soon Won Hong Jong Won Kim Seung Ho Choi Jae Yong Cho | 2012 | World Journal of Gastroenterology2012，18，30： | 19 |
| 5 | Treatment strategies using adefovir dipivoxil for individuals with lamivudine-resistant chronic hepatitis B显示文摘AIM:To investigate retrospectively the long-term efficacy of various treatment strategies using adefovir dipivoxil(adefovir) in patients with lamivudine-resistant chronic hepatitis B.METHODS:We included 154 consecutive patients in two treatment groups:the 'add-on' group(n = 79),in which adefovir was added to ongoing lamivudine treatment due to lamivudine resistance,and the 'switch/combination' group(n = 75),in which lamivudine was first switched to adefovir and then re-added later as needed.The 'switch/combination' group was then divided into two subgroups depending on whether participants followed(group A,n = 30) or violated(group B,n = 45) a proposed treatment strategy that determined whether to add lamivudine based on the serum hepatitis B virus(HBV) DNA levels(< 60 IU/mL or not) after 6 mo of treatment(roadmap concept).RESULTS:The cumulative probability of virologic response(HBV DNA < 60 IU/mL) was higher in group A than in the 'add-on' group and in group B(P < 0.001).In contrast,the cumulative probability of virologic breakthrough was lower in the 'add-on' group than in group B(P = 0.002).Furthermore,the risk of virologic breakthrough in the multivariate analysis was significantly lower in the 'add-on' group than in group A(hazard ratio = 0.096;95%CI,0.015-0.629;P = 0.015).CONCLUSION:The selective combination of adefovir with lamivudine based upon early treatment responses increased the odds of virologic breakthrough relative to the use of uniform combination therapy from the beginning of treatment. | Tae Jung Yun Jin Yong Jung Chang Ha Kim Soon Ho Um Hyonggin An Yeon Seok Seo Jin Dong Kim Hyung Joon Yim Bora Keum Yong Sik Kim Yoon Tae Jeen Hong Sik Lee Hoon Jai Chun Chang Duck Kim Ho Sang Ryu | 2012 | World Journal of Gastroenterology2012，18，47： | 19 |
| 6 | Computed tomography and magnetic resonance imaging evaluation of lymph node metastasis in early colorectal cancer显示文摘AIM: To assess the role of computed tomography(CT) and magnetic resonance imaging(MRI) and establish imaging criteria of lymph node metastasis in early colorectal cancer.METHODS: One hundred and sixty patients with early colorectal cancer were evaluated for tumor location, clinical history of polypectomy, depth of tumor invasion, and lymph node metastasis. Two radiologists assessed preoperative CT and/or MRI for the primary tumor site detectability, the presence or absence of regional lymph node, and the size of the largest lymph node. Demographic, imaging, and pathologic findings were compared between the two groups of patients based on pathologic lymph node metastasis and optimal size criterion was obtained.RESULTS: The locations of tumor were ascending, transverse, descending, sigmoid colon, and rectum. One hundred and sixty early colorectal cancers were classified into 3 groups based on the pathological depth of tumor invasion; mucosa, submucosa, and depth unavailable. A total of 20(12.5%) cancers with submucosal invasion showed lymph node metastasis. Lymph nodes were detected on CT or MRI in 53 patients. The detection rate and size of lymph nodes were significantly higher(P = 0.000, P = 0.044, respectively) in patients with pathologic nodal metastasis than in patients without nodal metastasis. Receiver operating curve analysis showed that a cut-off value of 4.1 mm is optimal with a sensitivity of 78.6% and specificity of 75%.CONCLUSION: The short diameter size criterion of≥ 4.1 mm for metastatic lymph nodes was optimal for nodal staging in early colorectal cancer. | Joonsung Choi Soon Nam Oh Dong-Myung Yeo Won Kyung Kang Chan-Kwon Jung Sang Woo Kim Michael Yong Park | 2015 | World Journal of Gastroenterology2015，21，2： | 16 |
| 7 | Safety and efficacy of tenofovir in chronic hepatitis B-related decompensated cirrhosis显示文摘AIM To evaluate the safety and efficacy of tenofovir disoproxil fumarate(TDF) as a first-line therapy in decompensated liver disease. METHODS We enrolled 174 chronic hepatitis B-related liver cirrhosis patients treated with 300 mg/d TDF at six Korean centers. Of the 174 cirrhosis patients, 57 were assigned to the decompensated cirrhosis group and 117 were assigned to the compensated cirrhosis group. We followed the patients for 12 mo and evaluated clinical outcomes, including biochemical, virological, and serological responses. We also evaluated changes in hepatic and renal function and compared the decompensated and compensated cirrhosis groups. RESULTS The 1-year complete virological response(CVR) and Hepatitis B e antigen(HBe Ag) seroconversion were seen in 70.2% and 14.2% in the decompensated cirrhosis group, respectively. The rates of HBe Ag seroconversion/loss and ALT normalization at month 12 were similar in both groups. TDF treatment was also effective for decreasing the level of hepatitis B virus(HBV) DNA in both groups, but CVR was higher in the compensated group(88.9% vs 70.2%, P = 0.005). Tenofovir treatment for 12 mo resulted in improved Child-Turcotte-Pugh(CTP) and model for end-stage liver disease(MELD) scores in decompensated group(P < 0.001). Of the 57 decompensated patients, 39(68.4%) achieved CTP class A and 27(49.1%) showed improvement in the CTP score of 2 points after 12 mo of TDF. The observed rate of confirmed 0.5 mg/d L increases in serum levels of creatinine in the decompensated and compensated cirrhosis group were 7.0% and 2.5%, respectively(P < 1.000).CONCLUSION TDF therapy in decompensated cirrhosis patients was effective for decreasing HBV DNA levels and improving hepatic function with relatively lower CVR than in compensated cirrhosis. Thus, physicians should carefully monitor not only renal function but also treatment responses when using TDF in decompensated cirrhosis patients. | Soon Kyu Lee Myeong Jun Song Seok Hyun Kim Byung Seok Lee Tae Hee Lee Young Woo Kang Suk Bae Kim Il Han Song Hee Bok Chae Soon Young Ko Jae Dong Lee | 2017 | World Journal of Gastroenterology2017，23，13： | 14 |
| 8 | Invasive and non-invasive diagnosis of cirrhosis and portal hypertension显示文摘With advances in the management and treatment of advanced liver disease,including the use of antiviral therapy,a simple,one stage description for advanced fibrotic liver disease has become inadequate.Although refining the diagnosis of cirrhosis to reflect disease heterogeneity is essential,current diagnostic tests have not kept pace with the progression of this new paradigm.Liver biopsy and hepatic venous pressure gradient measurement are the gold standards for the estimation of hepatic fibrosis and portal hypertension(PHT),respectively,and they have diagnostic and prognostic value.However,they are invasive and,as such,cannot be used repeatedly in clinical practice.The ideal noninvasive test should be safe,easy to perform,inexpensive,reproducible as well as to give numerical and accurate results in real time.It should be predictive of long term outcomes related with fibrosis and PHT to allow prognostic stratification.Recently,many types of noninvasive alternative tests have been developed and are under investigation.In particular,imaging and ultrasound based tests,such as transient elastography,have shown promising results.Although most of these noninvasive tests effectively identify severe fibrosis and PHT,the methods available for diagnosing moderate disease status are still insufficient,and further investigation is essential to predict outcomes and individualize therapy in this field. | Moon Young Kim Woo Kyoung Jeong Soon Koo Baik | 2014 | World Journal of Gastroenterology2014，20，15： | 13 |
| 9 | Treatment outcome of localized Helicobacter pylori-negative low-grade gastric MALT lymphoma显示文摘AIM: To investigate treatment outcome of Helicobacter pylori (H.pylori )-negative low-grade gastric mucosaassociated lymphoid tissue (MALT) lymphoma.METHODS: In this study,we retrospectively reviewed the clinical outcome and clinicopathologic factors of stage Ⅰ E H.pylori -negative low-grade gastric MALT lymphoma cases from August 1998 to June 2009.RESULTS: A total of eleven patients with H.pylori -negative low-grade gastric MALT lymphoma were enrolled in the study and received anti-H.pylori eradication treatment and/or radiotherapy or excisional therapy.Complete remission (CR) of gastric MALT lymphoma was achieved in all patients.The time to CR was 1-66 mo (median,1 mo).CONCLUSION: Eradication therapy may be offered as an initial treatment option even in cases of localized H.pylori -negative gastric MALT lymphoma. | Hyung Soon Park Yu Jin Kim Woo Ick Yang Chang Ok Suh Yong Chan Lee | 2010 | World Journal of Gastroenterology2010，16，17： | 13 |
| 10 | Prognostic value of inflammation-based markers in patients with pancreatic cancer administered gemcitabine and erlotinib显示文摘AIM: To evaluate the value of systemic inflammationbased markers as prognostic factors for advanced pancreatic cancer(PC). METHODS: Data from 82 patients who underwent combination chemotherapy with gemcitabine and erlotinib for PC from 2011 to 2014 were collected retrospectively. Data that included the neutrophil-to-lymphocyte ratio(NLR), the platelet-to-lymphocyte ratio, and the C-reactive protein(CRP)-to-albumin(CRP/Alb) ratio were analyzed. Kaplan-Meier curves, and univariate and multivariate Cox proportional hazards regression analyses were used to identify the prognostic factors associated with progression-free survival(PFS) and overall survival(OS). RESULTS: The univariate analysis demonstrated the prognostic value of the NLR(P = 0.049) and the CRP/Alb ratio(P = 0.047) in relation to PFS, and a positiverelationship between an increase in inflammation-based markers and a poor prognosis in relation to OS. The multivariate analysis determined that an increased NLR(hazard ratio = 2.76, 95%CI: 1.33-5.75, P = 0.007) is an independent prognostic factor for poor OS. There was no association between the PLR and the patients' prognoses in those who had received chemotherapy that comprised gemcitabine and erlotinib in combination. The Kaplan-Meier method and the log-rank test determined significantly worse outcomes in relation to PFS and OS in patients with an NLR > 5 or a CRP/Alb ratio > 5.CONCLUSION: Systemic inflammation-based markers, including increases in the NLR and the CRP/Alb ratio, may be useful for predicting PC prognoses. | Jae Min Lee Hong Sik Lee Jong Jin Hyun Hyuk Soon Choi Eun Sun Kim Bora Keum Yeon Seok Seo Yoon Tae Jeen Hoon Jai Chun Soon Ho Um Chang Duck Kim | 2016 | World Journal of Gastrointestinal Oncology2016，8，7： | 12 |
| 11 | Role of surgical resection for multiple hepatocellular carcinomas显示文摘AIM:To clarify the role of surgical resection for multiple hepatocellular carcinomas(HCCs)compared to transarterial chemoembolization(TACE)and liver transplantation(LT). METHODS:Among the HCC patients who were managed at Yonsei University Health System between January 2003 and December 2008,160 patients who met the following criteria were retrospectively enrolled:(1) two or three radiologically diagnosed HCCs;(2)no radiologic vascular invasion;(3)Child-Pugh class A;(4) main tumor smaller than 5 cm in diameter;and(5) platelet count greater than 50 000/mm3.Long-term outcomes were compared among the following three treatment modalities:surgical resection or combined radiofrequency ablation(RFA)(n=36),TACE(n=107), and LT(n=17).The survival curves were computed using the Kaplan-Meier method and compared with a log-rank test.To identify the patients who gained a survival benefit from surgical resection,we also investigated prognostic factors for survival following surgical resection.Multivariate analyses of the prognostic factors for survival were performed using the Cox proportional hazard model. RESULTS:The overall survival(OS)rate was significantly higher in the surgical resection group than in the TACE group(48.1%vs 28.9%at 5 years,P<0.005). LT had the best OS rate,which was better than that of the surgical resection group,although the difference was not statistically significant(80.2%vs 48.1%at 5 years,P=0.447).The disease-free survival rates were also significantly higher in the LT group than in the surgical resection group(88.2%vs 11.2%at 5 years, P<0.001).Liver cirrhosis was the only significant prognostic factor for poor OS after surgical resection. Clinical liver cirrhosis rates were 55.6%(20/36)in the resection group and 93.5%(100/107)in the TACE group.There were 19 major and 17 minor resections. En bloc resection was performed in 23 patients,multisite resection was performed in 5 patients,and combined resection with RFA was performed in 8 patients. In the TACE group,only 34 patients(31.8%)were recorded as having complete remission after primary TACE.Seventy-two patients(67.3%)were retreated with repeated TACE combined with other therapies. In patients who underwent surgical resection,the 16 patients who did not have cirrhosis had higher 5-year OS and disease-free survival rates than the 20 patients who had cirrhosis(80.8%vs 25.5%5-year OS rate, P=0.006;22.2%vs 0%5-year disease-free survival rate,P=0.048).Surgical resection in the 20 patients who had cirrhosis did not provide any survival benefit when compared with TACE(25.5%vs 24.7%5-year OS rate,P=0.225).Twenty-nine of the 36 patients who underwent surgical resection experienced recur-rence.Of the patients with cirrhosis,80%(16/20) were within the Milan criteria at the time of recurrence CONCLUSION:Among patients with two or three HCCs, no radiologic vascular invasion,and tumor diameters≤ 5 cm,surgical resection is recommended only in those without cirrhosis. | Sung Hoon Choi Gi Hong Choi Seung Up Kim Jun Yong Park Dong Jin Joo Man Ki Ju Myoung Soo Kim Jin Sub Choi Kwang Hyub Han Soon Il Kim | 2013 | World Journal of Gastroenterology2013，19，3： | 12 |
| 12 | Efficacy of Saam acupuncture treatment on improvement of immune cell numbers in cancer patients:a pilot study显示文摘OBJECTIVE: To collect preliminary data on the effects of Saam acupuncture with regard to the immunity in cancer patients.METHODS: Ten cancer patients were analyzed for improvements in immunity. Acupuncture was applied at the 5 acupuncture points, Jingqu(LU 8), Zutonggu(BL 66), Yanggu(SI 5), Yangchi(TE 4), and Zhongwan(CV 12) for 2 weeks with 4 sessions. We assessed the effect of Korean Saam acupuncture on the immune system in cancer patients by measuring particular blood cell subsets, including CD3 +,CD4+, CD8+, CD19+, and CD56+ cells, as well as total white blood cell count, absolute neutrophil count, and fatigue score. The measurement was performed before and after acupuncture and at a 2-week follow-up.RESULTS: There was a statistically significant increase in the number of CD3+(P=0.023) and CD8+ cells(P<0.001) and T-cell subsets, as well as a decrease in the fatigue severity scale(FSS) score(P=0.001) after Saam acupuncture using the 5 acupoints.CONCLUSION: Acupuncture may improve the immune system by increasing the counts of a few immune cells and relieve fatigue in cancer patients by decreasing FSS scores. Although this was a non-controlled study, it constitutes preliminary research investigating the potential effects of Saam acupuncture in increasing the counts of several immune cells in cancer patients. | Dae-Joon Kim Seong-Hoon Park Jung-Chul Seo Kyung Soon Kim Ki Cheul Sohn Im Hee Shin Hun Mo Ryoo | 2014 | Journal of Traditional Chinese Medicine2014，34，5： | 11 |
| 13 | Overexpression of miR-196b and HOXA10 characterize a poor-prognosis gastric cancer subtype显示文摘AIM:To identify molecular biologic differences between two gastric adenocarcinoma subgroups presenting different prognoses through the analysis of microRNA and protein expression.METHODS:Array technologies were used to generate1146 microRNAs and 124 proteins expression profiles of samples from 60 patients with gastric cancer.For the integrative analysis,we used established mRNA expression data published in our previous study.Whole mRNA expression levels were acquired from microarray data for 60 identical gastric cancer patients.Two gastric adenocarcinoma subgroups with distinct mRNA expression profiles presented distinctly different prognoses.MicroRNA and protein expression patterns were compared between gastric cancer tissue and normal gastric tissue and between two different prognostic groups.Aberrantly expressed microRNA,associated mRNA,and protein in patients with poor-prognosis gastric cancer were validated by quantitative reverse transcription polymerase chain reaction and immunochemistry in independent patients.RESULTS:We obtained the expression data of 1146microRNAs and 124 cancer-related proteins.Four microRNAs were aberrantly expressed in the two prognostic groups and in cancer vs non-cancer tissues(P<0.05).In the poor-prognosis group,miR-196b,miR-135b,and miR-93 were up-regulated and miR-29c*was down-regulated.miR-196b expression positively correlated with Homeobox A10(HOXA10)expression(r=0.726,P<0.001),which was significantly increased in poor-prognosis patients(P<0.001).Comparing gastric cancer with non-cancer tissues,46/124 proteins showed differential expression(P<0.05);COX2(P<0.001)and cyclin B1(P=0.017)were clearly overexpressed in the poor-prognosis group.CONCLUSION:Co-activation of miR-196b and HOXA10characterized a poor-prognosis subgroup of patients with gastric cancer.Elucidation of the biologic function of miR-196b and HOXA10 is warranted. | Jae Yun Lim Sun Och Yoon So-Young Seol Soon Won Hong Jong Won Kim Seung Ho Choi Ju-Seog Lee Jae Yong Cho | 2013 | World Journal of Gastroenterology2013，19，41： | 10 |
| 14 | Endoscopic submucosal tunnel dissection salvage technique for ulcerative early gastric cancer显示文摘Endoscopic submucosal dissection is an effective treatment modality for early gastric cancer(EGC), though the submucosal fibrosis found in ulcerative EGC is an obstacle for successful treatment. This report presents two cases of ulcerative EGC in two males, 73- and 80-year-old, with severe fibrosis. As endoscopic ultrasonography suggested that the EGCs had invaded the submucosal layer, the endoscopic submucosal tunnel dissection salvage technique was utilized for complete resection of the lesions. Although surgical gastrectomy was originally scheduled, the two patients had severe coronary heart disease, and surgeries were refused because of the risks associated with their heart conditions. The endoscopic submucosal tunnel dissection salvage technique procedures described in these cases were performed under conscious sedation, and were completed within 30 min. The complete en bloc resection of EGC using endoscopic submucosal tunnel dissection salvage technique was possible with a free resection margin, and no other complications were noted during the procedure. This is the first known report concerning the use of the endoscopic submucosal tunnel dissection salvage technique salvage technique for treatment of ulcerative EGC. We demonstrate that endoscopic submucosal tunnel dissection salvage technique it is a feasible method showing several advantages over endoscopic submucosal dissection for cases of EGC with fibrosis. | Hyuk Soon Choi Hoon Jai Chun Min Ho Seo Eun Sun Kim Bora Keum Yeon Seok Seo Yoon Tae Jeen Hong Sik Lee Soon Ho Um Chang Duck Kim Ho Sang Ryu | 2014 | World Journal of Gastroenterology2014，20，27： | 8 |
| 15 | Outcome of transarterial chemoembolization-based multi-modal treatment in patients with unresectable hepatocellular carcinoma显示文摘AIM:To investigate the efficacy and safety of transarterial chemoembolization(TACE)-based multimodal treatment in patients with large hepatocellular carcinoma(HCC).METHODS:A total of 146 consecutive patients were included in the analysis,and their medical records and radiological data were reviewed retrospectively.RESULTS:In total,119 patients received TACE-based multi-modal treatments,and the remaining 27 received conservative management.Overall survival(P<0.001)and objective tumor response(P=0.003)were significantly better in the treatment group than in the conservative group.After subgroup analysis,survival benefits were observed not only in the multi-modal treatment group compared with the TACE-only group(P=0.002)but also in the surgical treatment group compared with the loco-regional treatment-only group(P<0.001).Multivariate analysis identified tumor stage(P<0.001)and tumor type(P=0.009)as two independent pre-treatment factors for survival.After adjusting for significant pre-treatment prognostic factors,objective response(P<0.001),surgical treatment(P=0.009),and multi-modal treatment(P=0.002)were identified as independent post-treatment prognostic factors.CONCLUSION:TACE-based multi-modal treatments were safe and more beneficial than conservative management.Salvage surgery after successful downstaging resultedin long-term survival in patients with large,unresectable HCC. | Do Seon Song Soon Woo Nam Si Hyun Bae Jin Dong Kim Jeong Won Jang Myeong Jun Song Sung Won Lee Hee Yeon Kim Young Joon Lee Ho Jong Chun Young Kyoung You Jong Young Choi Seung Kew Yoon | 2015 | World Journal of Gastroenterology2015，21，8： | 7 |
| 16 | Treatment and prognosis of hepatic epithelioid hemangioendothelioma based on SEER data analysis from 1973 to 2014显示文摘Background: Hepatic epithelioid hemangioendothelioma (HEH) is a rare tumor of vascular origin with an unknown etiology, a low incidence, and a variable natural course. We evaluated the management and prognosis of HEH from the Surveillance, Epidemiology and End Results (SEER) program and changes in treatment modalities of HEH over 30 years. Methods: From 1973 to 2014 in the SEER database, we selected patients diagnosed with HEH. We analyzed the clinical characteristics, patterns of management, and clinical outcomes of patients with HEH. Results: We identi ed 79 patients with HEH (median age: 54.0 years;male to female ratio: 1:2.6). The initial extent of disease was local in 22 (27.8%) patients, regional metastasis in 22 (27.8%), distant metas-tasis in 31 (39.2%) and unknown in 4 (5.1%). The median size of primary tumor was 3.85 cm (interquartile range, 2.50 7.93 cm). Among 74 patients with available management data, the most common manage-ment was no treatment (29/74, 39.2%), followed by chemotherapy only (22/74, 29.7%), liver resection-based (13/74, 17.6%), and transplantation-based therapy (6/74, 8.1%). The 5-year cancer-speci c survival rate was 57.8%. Patients who underwent surgical treatment had signi cantly higher survival than those who underwent non-surgical treatment (5-year survival;88% vs. 49%, P=0.019). Multivariate analysis revealed that surgical therapy was the only independent prognostic factor for survival (hazard ratio: 0.20, P=0.040). Conclusions: Resection or liver transplantation is worth considering for treatment of patients with HEH. | O Kyu Noh Soon Sun Kim Min Jae Yang Sun Gyo Lim Jae Chul Hwang Hyo Jung Cho Jae Youn Cheong Sung Won Cho | 2020 | Hepatobiliary & Pancreatic Diseases International2020，19，1： | 7 |
| 17 | Comparison of sequential and 7-,10-,14-d triple therapy for Helicobacter pylori infection显示文摘AIM:To compare the effectiveness of sequential therapy for Helicobacter pylori(H.pylori) infection with that of triple therapy of varying durations.METHODS:The 460 patients enrolled in this study had H.pylori-associated gastritis or a gastric or duodenal ulcer.After screening,H.pylori-infected patients were randomly assigned to receive either conventional triple therapy for 7,10 or 14 d,or a new 10-d sequential therapy.Each of the 4 treatment groups included 115 patients.The outcomes of eradication therapy were assessed 4 wk after treatment by the urea breath test and histology.RESULTS:The overall eradication rate was 81.0%,and eradication rates were 75.7% for 7-d conventional triple therapy,81.9% for 10-d conventional triple therapy,84.4% for 14-d conventional triple therapy,and 82.0% for 10-d sequential therapy.Neither intention-to-treat analysis nor per protocol analysis showed significant differences in eradication rates using sequential therapy or the standard triple therapy(P = 0.416 and P = 0.405,respectively).CONCLUSION:There are no significant differences between 10-d sequential eradication therapy for H.pylori and any duration of standard triple treatment in Korean patients. | Hyuk Soon Choi Hoon Jai Chun Sang Hoon Park Bora Keum Yeon Seok Seo Yong Sik Kim Yoon-Tae Jeen Soon Ho Um Hong Sik Lee Chang Duck Kim Ho Sang Ryu | 2012 | World Journal of Gastroenterology2012，18，19： | 7 |
| 18 | Mesenchymal stem cell therapy for cirrhosis: Present and future perspectives显示文摘Cirrhosis occurs as a result of various chronic liver injuries,which may be caused by viral infections,alcohol abuse and the administration of drugs and chemicals. Recently,bone marrow cells(BMCs),hematopoietic stem cells(HSCs) and mesenchymal stem cells(MSCs) have been used for developing treatments for cirrhosis. Clinical trials have investigated the therapeutic potential of BMCs,HSCs and MSCs for the treatment of cirrhosis based on their potential to differentiate into hepatocytes. Although the therapeutic mechanisms of BMC,HSC and MSC treatments are still not fully characterized,the evidence thus far has indicated that the potential therapeutic mechanisms of MSCs are clearer than those of BMCs or HSCs with respect to liver regenerative medicine. MSCs suppress inflammatory responses,reduce hepatocyte apoptosis,increase hepatocyte regeneration,reverse liver fibrosis and enhance liver functionality. This paper summarizes the clinical studies that have used BMCs,HSCs and MSCs in patients with liver failure or cirrhosis. We also present the potential therapeutic mechanisms of BMCs,HSCs and MSCs for the improvement of liver function. | Young Woo Eom Gaeun Kim Soon Koo Baik | 2015 | World Journal of Gastroenterology2015，21，36： | 6 |
| 19 | Clinical significance of the leptin and leptin receptor expressions in prostate tissues显示文摘瞄准:在良性的专业版静电干扰增生(BPH ) 和前列腺癌症(PCa ) 计算 leptin 和 leptin 受体的表达式,并且调查他们是否与 PCa 的开发和前进被联系。方法:染色的 Immunohistochemical 被执行在 BPH 和 PCa 检验 leptin 和 leptin 受体的表示。PCa 被划分成三个组:局部性的 PCa,局部地先进的 PCa 和变形 PCa。积极染色被识别,积极染色的百分比被分级。我们也估计了在格利森分数和身体团索引(BMI ) 和 PCa 之间的关系。结果:在 PCa 的 leptin 表示的百分比在 BPH 比那显著地高(P <
0.01 ) 。为 PCa 组, leptin 的表示层次与局部性的 PCa 和变形 PCa 显示出可观的关联(P <
0.05 ) 。然而, Leptin 受体没揭示 BPH 和 PCa 之间的明确的差别。leptin 的表示显示了区分得好的 PCa 之间的重要差别(格利森 20 ≤
6 ) 并且糟糕区分的 PCa (格利森分数 8 10 )(P <
0.05 ) 。在在 PCa 和 BMI 的 leptin 表示水平之间的关系不是显著的(P= 0.447 ) 。结论:我们的结果建议 leptin 可能在 PCa 的 carcinogenesis 和前进上有支持的效果。 | Jung Hoon Kim Shin Young Lee Soon Chul Myung Young Sun Kim Tae-Hyoung Kim Mi Kyung Kim | 2008 | Asian Journal of Andrology2008，10，6： | 6 |
| 20 | Detection of early gastric cancer using hydro-stomach CT:Blinded vs unblinded analysis显示文摘AIM:To evaluate the difference in diagnostic performance of hydro-stomach computed tomography(CT) to detect early gastric cancer(EGC) between blinded and unblinded analysis and to assess independent factors affecting visibility of cancer foci.METHODS:Two radiologists initially blinded and then unblinded to gastroscopic and surgical-histological findings independently reviewed hydro-stomach CT images of 110 patients with single EGC.They graded the visibility of cancer foci for each of three gastric segments(upper,middle and lower thirds) using a 4-point scale(1:definitely absent,2:probably absent,3:probably present,and 4:definitely present).The sensitivity and specificity for detecting an EGC were calculated.Intraobserver and interobserver agreements were analyzed.The visibility of an EGC was evaluated with regard to tumor size,invasion depth,gastric segments,histological type and gross morphology using univariate and multivariate analysis.RESULTS:The respective sensitivities and specificities [reviewer 1:blinded,20%(22/110) and 98%(215/220);unblinded,27%(30/110) and 100%(219/220)/reviewer 2:blinded,19%(21/110) and 98%(216/220);unblinded,25%(27/110) and 98%(215/220)] were not significantly different.Although intraobserver agreements were good(weighted κ = 0.677 and 0.666),interobserver agreements were fair(blinded,0.371) or moderate(unblinded,0.558).For both univariate and multivariate analyses,the tumor size and invasion depth were statistically significant factors affecting visibility.CONCLUSION:The diagnostic performance of hydrostomach CT to detect an EGC was not significantly different between blinded and unblinded analysis.The tumor size and invasion depth were independent factors for visibility. | Ki Jeong Park Min Woo Lee Ji Hyun Koo Yulri Park Heejung Kim Dongil Choi Soon Jin Lee | 2011 | World Journal of Gastroenterology2011，17，8： | 6 |
