1Ellagic acid induces apoptosis through inhibition of nuclear factor κB in pancreatic cancer cells显示文摘AIM:To determine the effect of ellagic acid on apop-tosis and proliferation in pancreatic cancer cells and to determine the mechanism of the pro-survival effects of ellagic acid. METHODS:The effect of ellagic acid on apoptosis was assessed by measuring Phosphatidylserine externalization,caspase activity,mitochondrial membrane potential and DNA fragmentation;and proliferation by measuring DNA thymidine incorporation. Mitochondrial membrane potential was measured in permeabilized cells,and in isolated mitochondria. Nuclear factor kB(NF-kB) activity was measured by electromobility shift assay(EMSA) . RESULTS:We show that ellagic acid,a polyphenolic compound in fruits and berries,at concentrations 10 to 50 mmol/L stimulates apoptosis in human pancreatic adenocarcinoma cells. Further,ellagic acid decreases proliferation by up to 20-fold at 50 mmol/L. Ellagic acid stimulates the mitochondrial pathway of apoptosis associated with mitochondrial depolarization,cytochrome C release,and the downstream caspaseactivation. Ellagic acid does not directly affect mitochondria. Ellagic acid dose-dependently decreased NF-kB binding activity. Furthermore,inhibition of NF-kB activity using IkB wild type plasmid prevented the effect of ellagic acid on apoptosis. CONCLUSION:Our data indicate that ellagic acid stimulates apoptosis through inhibition of the prosu-rvival transcription factor NF-kB.Mouad Edderkaoui Irina Odinokova Izumi Ohno Ilya Gukovsky Vay Liang W Go Stephen J Pandol Anna S Gukovskaya 2008World Journal of Gastroenterology2008,14,23:30
2Helicobacter pylori-related chronic gastritis as a risk factor for colonic neoplasms显示文摘To summarize the current views and insights on associations between Helicobacter pylori(H. pylori)-related chronic gastritis and colorectal neoplasm, we reviewed recent studies to clarify whether H. pylori infection/H. pylori-related chronic gastritis is associated with an elevated risk of colorectal neoplasm. Recent studies based on large databases with careful control for confounding variables have clearly demonstrated an increased risk of colorectal neoplasm associated with H. pylori infection. The correlation between H. pylori-related chronic atrophic gastritis(CAG) and colorectal neoplasm has only been examined in a limited number of studies. A recent large study using a national histopathological database, and our study based on the stage of H. pylori-related chronic gastritis as determined by serum levels of H. pylori antibody titer and pepsinogen, indicatedthat H. pylori-related CAG confers an increased risk of colorectal neoplasm, and more extensive atrophic gastritis will probably be associated with even higher risk of neoplasm. In addition, our study suggested that the activity of H. pylori-related chronic gastritis is correlated with colorectal neoplasm risk. H. pylori-related chronic gastritis could be involved in an increased risk of colorectal neoplasm that appears to be enhanced by the progression of gastric atrophy and the presence of active inflammation.Izumi Inoue Jun Kato Hideyuki Tamai Mikitaka Iguchi Takao Maekita Noriko Yoshimura Masao Ichinose 2014World Journal of Gastroenterology2014,20,6:25
3Effect of Clostridium butyricum on fecal flora in Helicobacter pylori eradication therapy显示文摘AIM: To investigate the effect of probiotic bacterium,Clostridium butyricum MIYAIRI 588 strain (CBM) on the changes of the fecal flora in Helicobacter pylori(H pylori)treatment.METHODS: Thirty-five patients with gastric or duodenal ulcers positive for Hpylori were randomized either to 1 wk amoxicillin, clarithromycin, lansoprazole (Group 1) or to the same regimen supplemented with CBM 7 dahead of the triple therapy (Group 2). Stool samples were collected before and 2, 4, 7, 15, and 22 d after the starting eradication therapy, and were examined intestinal flora. Patients were required to keep a diary record of their condition. RESULTS: Obligate anaerobes decreased significantly on d 2, 4, 8 and 15 in Group 1. On the other hand, they did not decrease significantly in Group 2. The Escherichiacoli was dominant bacterium in Enterobacteriaceae, butthat was replaced by other species such as Klebsiella and Enterobacter after eradication in Group 1. The change was suppressed in Group 2. Abdominal symptoms were less frequent in Group 2 than in Group 1.CONCLUSION: The combined use of CBM reduced the changes in the intestinal flora and decreased the incidence of gastrointestinal side effects.Izumi Shimbo Taketo Yamaguchi Takeo Odaka Kenichi Nakajima Akinori Koide Hidehiko Koyama Hiromitsu Saisho 2005World Journal of Gastroenterology2005,11,47:18
4Hyperglycemia is a significant prognostic factor of hepatocellular carcinoma after curative therapy显示文摘AIM:To evaluate whether metabolic factors are related to distant recurrence of hepatocellular carcinoma(HCC) and survival after curative treatment.METHODS:This retrospective study included 344 patients whose HCC was treated curatively by radiofrequency ablation(RFA) therapy.The mean age was 67.6 years and the mean observation period was 4.04 years.The etiological background of liver disease was hepatitis B virus infection in 30,hepatitis C virus infection in 278,excessive alcohol drinking in 9,and other in 27 patients.The Child-Pugh classification grade was A(n = 307) or B(n = 37).The number of HCC nodules was one in 260,two in 61,and three in 23 patients.For surveillance of HCC recurrence after curative therapy with RFA,patients were radiologically evaluated every 3 mo.Factors associated with distant recurrence of HCC or survival were studied.RESULTS:Inadequate maintenance of blood glucose in diabetic patients was associated with higher incidence of distant recurrence.The 1-,2-,and 3-year recurrence rates were significantly higher in diabetic patients with inadequate maintenance of blood glucose compared with the others:50.6% vs 26.8%,83.5% vs 54.4%,and 93.8% vs 73.0%,respectively(P = 0.0001).Inadequate maintenance of blood glucose was an independent predictor of distant recurrence [adjusted relative risk 1.97(95%CI,1.33-2.91),(P = 0.0007)] after adjustment for other risk factors,such as number of HCC nodules [2.03(95%CI,1.51-2.73),P < 0.0001] and initial level of serum alpha fetoprotein(AFP) [1.43(95%CI,1.04-1.97),P = 0.028].Obesity was not an independent predictor of recurrence.The incidence of distant recurrence did not differ between diabetic patients with adequate maintenance of blood glucose and non-diabetic patients.Among 232 patients who had HCC recurrence,138 had a second recurrence.The 1-,2-,and 3-year rates of second recurrence were significantly higher in diabetic patients with inadequate maintenance of blood glucose than in the others:9.0% vs 5.9%,53.1% vs 24.3%,and 69.6% vs 42.3%,respectively(P = 0.0021).Inadequate maintenance of blood glucose in diabetic patients [1.99(95%CI,1.23-3.22),P = 0.0049] and presence of multiple HCC nodules [1.53(95%CI,1.06-2.22),P = 0.024] were again significantly associated with second HCC recurrence.Inadequate maintenance of blood glucose in diabetic patients was also a significant predictor of poor survival [2.77(95%CI,1.38-5.57),P = 0.0046] independent of excessive alcohol drinking [6.34(95%CI,1.35-29.7),P = 0.019],initial level of serum AFP [3.40(95%CI,1.88-6.18),P < 0.0001] and Child-Pugh classification grade B [2.24(95%CI,1.12-4.46),P = 0.022].Comparing diabetic patients with inadequate maintenance of blood glucose vs the others,the 1-,2-,and 3-year survival rates were significantly lower in diabetic patients with inadequate maintenance of blood glucose:92% vs 99%,85% vs 96%,and 70% vs 92%,respectively(P = 0.0003).CONCLUSION:Inadequate maintenance of blood glucose in diabetic patients is a significant risk factor for recurrence of HCC and for poor survival after curative RFA therapy.Takanori Hosokawa Masayuki Kurosaki Kaoru Tsuchiya Shuya Matsuda Masaru Muraoka Yuichiro Suzuki Nobuharu Tamaki Yutaka Yasui Toru Nakata Takashi Nishimura Shoko Suzuki Ken Ueda Hiroyuki Nakanishi Jun Itakura Yuka Takahashi Namiki Izumi 2013World Journal of Gastroenterology2013,19,2:12

6Evaluation of the relationship between hepatocellular carcinoma location and transarterial chemoembolization efficacy显示文摘AIM To evaluate the relationship between the location of hepatocellular carcinoma(HCC) and the efficacy of transarterial chemoembolization(TACE).METHODS We evaluated 115 patients(127 nodules), excluding recurrent nodules, treated with TACE between January 2011 and June 2014. TACE efficacy was evaluated according to m RECIST. The HCC location coefficient was calculated as the distance from the central portal portion to the HCC center(mm)/liver diameter(mm) on multiplanar reconstruction images rendered(MPR) to visualize bifurcation of the right and left branches of the portal vein and HCC center. The HCC location coefficient was compared between complete response(CR) and non-CR groups in Child-Pugh grade A and B patients.RESULTS The median location coefficient of HCC among all nodules, the right lobe, and the medial segment was significantly higher in the CR group than in the non-CR group in the Child-Pugh grade A patients(0.82 vs 0.62, P < 0.001; 0.71 vs 0.59, P < 0.01; 0.81 vs 0.49, P < 0.05, respectively). However, there was no significant difference in the median location coefficient of the HCC in the lateral segment between in the CR and in the non-CR groups(0.67 vs 0.65, P > 0.05). On the other hand, in the Child-Pugh grade B patients, the HCC median location coefficient in each lobe and segment was not significantly different between in the CR and in the non-CR groups.CONCLUSION Improved TACE efficacy may be obtained for HCC in the peripheral zone of the right lobe and the medial segment in Child-Pugh grade A patients.Izumi Miki Satoru Murata Fumio Uchiyama Daisuke Yasui Tatsuo Ueda Fumie Sugihara Hidemasa Saito Hidenori Yamaguchi Ryusuke Murakami Chiaki Kawamoto Eiji Uchida Shin-ichiro Kumita 2017World Journal of Gastroenterology2017,23,35:8
7Biochemically curative surgery for gastrinoma in multiple endocrine neoplasia type 1 patients显示文摘AIM: To search for the optimal surgery for gastrinoma and duodenopancreatic neuroendocrine tumors in patients with multiple endocrine neoplasia type 1. METHODS: Sixteen patients with genetically confirmed multiple endocrine neoplasia type 1 (MEN 1) and Zollinger-Ellison syndrome (ZES) underwent resection of both gastrinomas and duodenopancreatic neuroendocrine tumors (NETs) between 1991 and 2009. For localization of gastrinoma, selective arterial secretagogue injection test (SASI test) with secretin or calcium solution was performed as well as somatostatin receptor scintigraphy (SRS) and other imaging methods such as computed tomography (CT) or magnetic resonance imaging (MRI). The modus of surgery for gastrinoma has been changed over time, searching for the optimal surgery: pancreaticoduodenectomy (PD) was first performed guided by localization with the SAST test, then local resection of duodenal gastrinomas with dissection of regional lymph nodes (LR), and recently pancreas-preserving total duodenectomy (PPTD) has been performed for multiple duodenal gastrinomas. RESULTS: Among various types of preoperative localizing methods for gastrinoma, the SASI test was the most useful method. Imaging methods such as SRS or CT made it essentially impossible to differentiate functioning gastrinoma among various kinds of NETs. However, recent imaging methods including SRS or CT were useful for detecting both distant metastases and ectopic NETs; therefore they are indispensable for staging of NETs. Biochemical cure of gastrinoma was achieved in 14 of 16 patients (87.5%); that is, 100% in 3 patients who underwent PD, 100% in 6 patients who underwent LR (although in 2 patients (33.3%) second LR was performed for recurrence of duodenal gastrinoma), and 71.4% in 7 patients who underwent PPTD. Pancreatic NETs more than 1 cm in diameter were resected either by distal pancreatectomy or enucleations, and no hepatic metastases have developed postoperatively. Pathological study of the resected specimens revealed co-existence of pancreatic gastrinoma with duodenal gastrinoma in 2 of 16 patients (13%), and G cell hyperplasia and/or microgastrinoma in the duodenal Brunner's gland was revealed in all of 7 duodenal specimens after PPTD. CONCLUSION: Aggressive resection surgery based on accurate localization with the SASI test was useful for biochemical cure of gastrinoma in patients with MEN 1.Masayuki Imamura Izumi Komoto Shuichi Ota Takuya Hiratsuka Shinji Kosugi Ryuichiro Doi Masaaki Awane Naoya Inoue 2011World Journal of Gastroenterology2011,17,10:5

9Response of Rice to Insect Elicitors and the Role of OsJAR1 in Wound and Herbivory-Induced JA-lle Accumulation显示文摘Plants produce jasmonic acid(JA) and its amino acid conjugate,jasmonoyl-L-isoleucine(JA-lle) as major defense signals in response to wounding and herbivory.In rice(Oryza sativa),JA and JA-lle rapidly increased after mechanical damage,and this increase was further amplified when the wounds were treated with oral secretions from generalist herbivore larvae,lawn armyworms(Spodoptera mauritia),revealing for the first time active perception mechanisms of herbivore-associated elicitor(s) in rice.In the rice genome, two OsJAR genes can conjugate JA and lle and form JA-lle in vitro;however,their function in herbivoryinduced accumulation of JA-lle has not been investigated.By functional characterization of TOS17 retrotransposon-tagged Osjar1 plants and their response to simulated herbivory,we show that OsJAR1 is essential for JA-lle production in herbivore-attacked,field-grown plants.In addition,OsJAFM was required for normal seed development in rice under field conditions.Our results suggest that OsJAR1 possesses at least two major functions in rice defense and development that cannot be complemented by the additional OsJAR2 gene function,although this gene previously showed overlapping enzyme activity in vitro.Kaori Fukumoto Kabir Md Alamgir Yuko Yamashita Izumi C.Mori Hideyuki Matsuura Ivan Galis 2013Journal of Integrative Plant Biology2013,55,8:5

11Peeling a giant ileal lipoma with endoscopic unroofing and submucosal dissection显示文摘Lipoma is relatively common in the colon but is less often in the small intestine. Most lipomas are incidentally detected at endoscopy and are usually small and asymptomatic. However, some of them can present with obstruction and/or intussusceptions. Surgical resection is commonly recommended to remove such significant lipomas with a limited pedicle and larger than 2 cm in size, as endoscopic resection may result in unfavorable complications such as intestinal perforations. We report a case of 62-year-old man presenting with hematochezia. Colonoscopy showed a submucosal tumor, about 50 mm in size, in the terminal ileum. A clinical diagnosis of lipoma was established based on the findings of colonoscopy and abdominal computed tomography (CT). As the patient complained of hematochezia and mild iron deficiency anemia associated with repeated tumor prolapse, we decided to remove his lipoma. Consequently, the lesion was completely removed en bloc . Although abdominal CT immediately after removal of the lesion showed a small amount of free air, conservative treatment was successfully carried out for the perforation. Histologically, the removed lesion was a lipoma.Takashi Morimoto Kuang-I Fu Hironori Konuma Yuko Izumi Syujirou Matsuyama Kanako Ogura Akihisa Miyazaki Sumio Watanabe 2010World Journal of Gastroenterology2010,16,13:4
12Effect of atrial natriuretic peptide on ischemia-reperfusion injury in a porcine total hepatic vascular exclusion model显示文摘AIM: To evaluate the effect of ANP on warm I/R injury in a porcine THVE model. METHODS: Miniature pigs (mini-pigs) weighing 16-24 kg were observed for 120 min after reperfusion following 120 min of THVE. The animals were divided into two groups. ANP (0.1 μg/kg per min) was administered to the ANP group (n = 7), and vehicle was administered to the control group (n = 7). Either vehicle or ANP was intravenously administered from 30 min before the THVE to the end of the experiment. Arterial blood was collected to measure AST, LDH, and TNF-α. Hepatic tissue blood ? ow (HTBF) was also measured. Liver specimens were harvested for p38 MAPK analysis and histological study. Those results were compared between the two groups. RESULTS: The AST and LDH levels were lower in the ANP group than in the control group; the AST levels were signifi cantly different between the two groups (60 min: 568.7 ± 113.3 vs 321.6 ± 60.1, P = 0.038 < 0.05, 120 min: 673.6 ± 148.2 vs 281.1 ± 44.8, P = 0.004 < 0.01). No signifi cant difference was observed in the TNF-α levels between the two groups. HTBF was higher in the ANP group, but the difference was not signif icant. A signifi cantly higher level of phosphorylated p38 MAPK was observed in the ANP group compared to the controlgroup (0 min: 2.92 ± 1.1 vs 6.38 ± 1.1, P = 0.011 < 0.05).Histological tissue damage was milder in the ANP group than in the control group. CONCLUSION: Our results show that ANP has a protective role in I/R injury with p38 MAPK activation in a porcine THVE model.Katsumi Kobayashi Kiyohiro Oshima Masato Muraoka Takahiko Akao Osamu Totsuka Hisashi Shimizu Hiroaki Sato Kazumi Tanaka Kenjiro Konno Koshi Matsumoto Izumi Takeyoshi 2007World Journal of Gastroenterology2007,13,25:4
13Endoscopic retrieval of a gastric trichobezoar显示文摘A 9-year-old girl presented with a chief complaint of abdominal pain. Esophagogastroduodenal endoscopy (EGD) identifi ed a long and large gastric trichobezoar extending into the duodenum. We attempted endoscopic retrieval after informed consent was obtained from the patient's mother. Initially, a gasper with 5-prolongs, com monly used for retrieval of endoscopically excised poly ps, failed to remove the whole trichobezoar. When a net was used instead, it proved impossible to remove the trichobezoar completely. Therefore, we withdrew the scope from the mouth, leaving the net grasping the tri co bezoar firmly in the stomach. Subsequently, we were able to retrieve about 70% of the trichobezoar manually by grasping the snare part of the net directly. A second pass found no deep laceration or perforation endoscopically. The remaining trichobezoar was completely retrieved with the net. The procedure was completed within 15 min. The retrieved specimens were34 cm in length and 100 g in weight. The patient was discharged uneventfully 5 d thereafter. She was advised to visit a psychiatrist to avoid suffering from a relapse. Follow-up EGD showed no trichobezoar, and the patient' s frontal hair grew back.Hironori Konuma Kuangi Fu Takashi Morimoto Takayoshi Shimizu Yuko Izumi Satoko Shiyanagi Masahiko Urao Akihisa Miyazaki Sumio Watanabe 2011World Journal of Gastrointestinal Endoscopy2011,3,1:4

151700 nm optical coherence microscopy enables minimally invasive,label-free,in vivo optical biopsy deep in the mouse brain显示文摘In vivo,minimally invasive microscopy in deep cortical and sub-cortical regions of the mouse brain has been challenging.To address this challenge,we present an in vivo high numerical aperture optical coherence microscopy(OCM)approach that fully utilizes the water absorption window around 1700nm;where ballistic attenuation in the brain is minimized.Key issues,including detector noise,excess light source noise,chromatic dispersion,and the resolution-speckle tradeoff,are analyzed and optimized.Imaging through a thinned-skull preparation that preserves intracranial space,we present volumetric imaging of cytoarchitecture and myeloarchitecture across the entire depth of the mouse neocortex,and some sub-cortical regions.In an Alzheimer's disease model,we report that findings in superficial and deep cortical layers diverge,highlighting the importance of deep optical biopsy.Compared to other microscopic techniques,our 1700nm OCM approach achieves a unique combination of intrinsic contrast,minimal invasiveness,and high resolution for deep brain imaging.Jun Zhu Hercules Rezende Freitas Izumi Maezawa Lee-way Jin Vivek J.Srinivasan 2021Light(Science & Applications)2021,10,8:3
16Distribution of HBV genotypes among HBV carriers in Benin:phylogenetic analysis and virological characteristics of HBV genotype E显示文摘AIM: To determine the distribution of Hepatitis B virus (HBV) genotypes in Benin, and to clarify the virological characteristics of the dominant genotype.METHODS: Among 500 blood donors in Benin, 21 HBsAg-positive donors were enrolled in the study. HBV genotypes were determined by enzyme immunoassay and restriction fragment length polymorphism. Complete genome sequences were determined by PCR and direct sequencing.RESULTS: HBV genotype E (HBV/E) was detected in 20/21 (95.2%), and HBV/A in 1/21 (4.8%). From the age-specific prevalence of HBeAg to anti-HBe seroconversion (SC) in 19 HBV/E subjects, SC was estimated to occur frequently in late teens in HBV/E.The comparison of four complete HBV/E genomes from HBeAg-positive subjects in this study and five HBV/E sequences recruited from the database revealed that HBV/E was distributed throughout West Africa with very low genetic divers ity (nucleotide homology 96.7-99.2%).Based on the sequences in the basic core promoter (BCP)to precore region of the nine HBV/E isolates compared to those of the other genotypes, a nucleotide substitution in the BCP, G1757A, was observed in HBV/E.CONCLUSION: HBV/E is predominant in the Republic of Benin, and SC is estimated to occur in late teens in HBV/E. The specific nucleotide substitution G1757A in BCP, which might influence the virological characteristics,is observed in HBV/E.Kei Fujiwara Yasuhito Tanaka Etsuro Orito Tomoyoshi Ohno Takanobu Kato Kanji Sugihara Izumi Hasegawa Mayumi Sakurai Kiyoaki Ito Atsushi Ozasa Yuko Sakamoto Isao Arita Ahmed El-Gohary Agossou Benoit Sophie I Ogoundele-Akplogan Namiko Yoshihara Ryuzo Ueda Masashi Mizokami 2005World Journal of Gastroenterology2005,11,41:3
17Prognostic significance of BMP and activin membrane-bound inhibitor in colorectal cancer显示文摘AIM: To investigate the clinical significance of BMP and activin membrane-bound inhibitor (BAMBI) which is a pseudoreceptor of transforming growth factor-beta (TGF-β) type Ⅰreceptors and acts as a negative regulator of TGF-β signaling and expression aberrantly elevated in colorectal cancers (CRCs). We studied BAMBI expression in CRCs. METHODS: We studied BAMBI expression in 183 surgically resected CRCs by immunochemical and immunoblotting analyses using a generated monoclonal anti-BAMBI antibody. Commercially available anti-β-catenin and anti-p53 antibodies were also applied for immunochemical analyses as a comparison control.RESULTS: Immunohistochemical analysis revealed that BAMBI expression was observed in 148 (80.8%), and strong BAMBI expression was observed in 46% of the CRCs. Strong BAMBI expression was positively correlated with histological type, depth of invasion, lymph node metastases, and tumor node metastasis (TNM) stage (P < 0.05). Clear associations were found between BAMBI and β-catenin (P = 0.035) and p53 (P = 0.049) expression. In curatively resected CRC, 5-year recurrence-free survival was 51.9% (P = 0.037) for strong BAMBI expression compared to 79.8% for weak BAMBI expression. In the Cox’s multivariate analysis, lymph node metastases (RR 6.685; P < 0.001) and depth of invasion (RR 14.0; P = 0.013) were signifi cant indicators for recurrence, and strong BAMBI expression (RR 2.26; P = 0.057) tended to be signifi cant. CONCLUSION: BAMBI was linked to a potentially aggressive tumor phenotype and predicted tumor recurrence and cancer-related death in CRC. BAMBI expression might be applicable in the routine clinical setting of CRC.Nozomi Togo Susumu Ohwada Shinji Sakurai Hiroyuki Toya Ichiro Sakamoto Tatsuya Yamada Tetsuhiro Nakano Ken Muroya Izumi Takeyoshi Takashi Nakajima Takashi Sekiya Yusuke Yamazumi Tsutomu Nakamura Tetsu Akiyama 2008World Journal of Gastroenterology2008,14,31:3
18Alpha-fetoprotein and des-gamma-carboxy-prothrombin at twenty-four weeks after interferon-based therapy predict hepatocellular carcinoma development显示文摘AIM: To investigate risk factors for development of hepatocellular carcinoma(HCC) in patients with hepatitis C virus-related liver cirrhosis(LC-C).METHODS: To evaluate the relationship between clinical factors including virological response and the development of HCC in patients with LC-C treated with interferon(IFN) and ribavirin, we conducted a multicenter, retrospective study in 14 hospitals in Japan. All patients had compensated LC-C with clinical or histological data available. HCC was diagnosed by the presence of typical hypervascular characteristics on computed tomography and/or magnetic resonance imaging.RESULTS: HCC was diagnosis in 50(21.6%) of 231 LC-C patients during a median observation period of 3.8 years after IFN and ribavirin therapy. Patients who developed HCC were older(P = 0.018) and had higher serum levels of pretreatment alpha-fetoprotein(AFP)(P = 0.038). Multivariate analysis revealed the following independent risk factors for HCC development: history of treatment for HCC [P < 0.001, odds ratio(OR) = 15.27, 95%CI: 4.98-59.51], AFP levels of ≥ 10 ng/m L(P = 0.009, OR = 3.89, 95%CI: 1.38-11.94), and des-γ-carboxy prothrombin(DCP) levels of ≥ 40 m AU/mL at 24 wk after the completion of IFN and ribavirin therapy(P < 0.001, OR = 24.43, 95%CI: 4.11-238.67).CONCLUSION: We suggested that the elevation of AFP and DCP levels at 24 wk after the completion of IFN and ribavirin therapy were strongly associated with the incidence of HCC irrespective of virological response among Japanese LC-C patients.Satoshi Shakado Shotaro Sakisaka Kazuaki Chayama Takeshi Okanoue Joji Toyoda Namiki Izumi Akihiro Matsumoto Tetsuo Takehara Akio Ido Yoichi Hiasa Kentaro Yoshioka Hideyuki Nomura Yoshiyuki Ueno Masataka Seike Hiromitsu Kumada 2015World Journal of Hepatology2015,7,27:3
