| 1 | Management of hepatitis B virus infection during treatment for hepatitis B virus-related hepatocellular carcinoma显示文摘Although liver resection is considered the most effective treatment for hepatocellular carcinoma(HCC), treatment outcomes are unsatisfactory because of the high rate of HCC recurrence. Since we reported hepatitis B e-antigen positivity and high serum hepatitis B virus(HBV) DNA concentrations are strong risk factors for HCC recurrence after curative resection of HBV-related HCC in the early 2000 s, many investigators have demonstrated the effects of viral status on HCC recurrence and post-treatment outcomes. These findings suggest controlling viral status is important to prevent HCC recurrence and improve survival after curative treatment for HBV-related HCC. Antiviral therapy after curative treatment aims to improve prognosis by preventing HCC recurrence and maintaining liver function. Therapy with interferon and nucleos(t)ide analogs may be useful for preventing HCC recurrence and improving overall survival in patients who have undergone curative resection for HBV-related HCC. In addition, reactivation of viral replication can occur after liver resection for HBV-related HCC. Antiviral therapy can be recommended for patients to prevent HBV reactivation. Nevertheless, further studies are required to establish treatment guidelines for patients with HBVrelated HCC. | Shoji Kubo Shigekazu Takemura Shogo Tanaka Hiroji Shinkawa Takayoshi Nishioka Akinori Nozawa Masahiko Kinoshita Genya Hamano Tokuji Ito Yorihisa Urata | 2015 | World Journal of Gastroenterology2015，21，27： | 19 |
| 2 | Non-invasive determination of hepatic steatosis by acoustic structure quantification from ultrasound echo amplitude显示文摘AIM:To use leptin-deficient(ob/ob) mice with demonstrated differences in steatosis levels to test a new diagnostic method using the acoustical structure quantification(ASQ) mode and the associated analytical parameter,'focal disturbance ratio'(FD-ratio).METHODS:Nine ob/ob mice,at 5,8,and 12 wk of age(n = 3 in each age group),were used as models for hepatic steatosis.Echo signals obtained from ultrasonography in the mice were analyzed by ASQ,which uses a statistical analysis of echo amplitude to estimate inhomogeneity in the diagnostic region.FD-ratio,as calculated from this analysis,was the focus of the present study.FD-ratio and fat droplet areas and sizes were compared between age groups.RESULTS:No fibrosis or inflammation was observed in any of the groups.The fat droplet area significantly(P < 0.01) increased with age from 1.25% ± 0.28% at 5 wk to 31.07% ± 0.48% at 8 wk to 51.69% ± 3.19% at 12 wk.The median fat droplet size also significantly(P < 0.01) increased with age,from 1.33(0.55-10.52) m at 5 wk,2.82(0.61-44.13) m at 8 wk and 6.34(0.66-81.83) m at 12 wk.The mean FD-ratio was 0.42 ± 0.11 at 5 wk,0.11 ± 0.05 at 8 wk,and 0.03 ± 0.02 at 12 wk.The FD-ratio was significantly lower at 12 wk than at 5 wk and 8 wk(P < 0.01).A significant negative correlation was observed between the FD-ratio and either the fat droplet area(r =-0.7211,P = 0.0017) or fat droplet size(r =-0.9811,P = 0.0052).CONCLUSION:This tool for statistical analysis of signals from ultrasonography using the FD-ratio can be used to accurately quantify fat in vivo in an animal model of hepatic steatosis,and may serve as a quantitative biomarker of hepatic steatosis. | Hidekatsu Kuroda Keisuke Kakisaka Naohisa Kamiyama Takayoshi Oikawa Mio Onodera Kei Sawara Kanta Oikawa Ryujin Endo Yasuhiro Takikawa Kazuyuki Suzuki | 2012 | World Journal of Gastroenterology2012，18，29： | 15 |
| 3 | Endoscopic ultrasound-guided choledochoduodenostomy in patients with failed endoscopic retrograde cholangiopancreatography显示文摘Endoscopic ultrasonography (EUS)-guided biliary drainage was performed for treatment of patients who have obstructive jaundice in cases of failed endoscopic retrograde cholangiopancreatography (ERCP). In the present study,we introduced the feasibility and outcome of EUS-guided choledochoduodenostomy in four patients who failed in ERCP. We performed the procedure in 2 papilla of Vater,including one resectable case,and 2 cases of cancer of the head of pancreas. Using a curved linear array echoendoscope,a 19 G needle or a needle knife was punctured transduodenally into the bile duct under EUS visualization. Using a biliary catheter for dilation,or papillary balloon dilator,a 7-Fr plastic stent was inserted through the choledochoduodenostomy site into the extrahepatic bile duct. In 3 (75%) of 4 cases,an indwelling plastic stent was placed,and in one case in which the stent could not be advanced into the bile duct,a naso-biliary drainage tube was placed instead. In all cases,the obstructive jaundice rapidly improved after the procedure. Focal peritonitis and bleeding not requiring blood transfusion was seen in one case. In this case,pancreatoduodenectomy was performed and the surgical findings revealed severe adhesion around the choledochoduodenostomy site. Although further studies and development of devices are mandatory,EUS-guided choledochoduodenostomy appears to be an effective alternative to ERCP in selected cases. | Takao Itoi Fumihide Itokawa Atsushi Sofuni Toshio Kurihara Takayoshi Tsuchiya Kentaro Ishii Shujiro Tsuji Nobuhito Ikeuchi Fuminori Moriyasu | 2008 | World Journal of Gastroenterology2008，14，39： | 13 |

| 5 | Chromoendoscopy of gastric adenoma using an acetic acid indigocarmine mixture显示文摘AIM:To investigate the usefulness of chromoendoscopy,using an acetic acid indigocarmine mixture(AIM),for gastric adenoma diagnosed by forceps biopsy.METHODS:A total of 54 lesions in 45 patients diagnosed as gastric adenoma by forceps biopsy were prospectively enrolled in this study and treated by endoscopic submucosal dissection(ESD)between January 2011 and January 2012.AIM-chromoendoscopy(AIMCE)was performed followed by ESD.AIM solution was sprinkled and images were recorded every 30 s for 3min.Clinical characteristics such as tumor size(<2cm,≥2 cm),surface color in white light endoscopy(WLE)(whitish,normochromic or reddish),macroscopic appearance(flat or elevated,depressed),and reddish change in AIM-CE were selected as valuables.RESULTS:En bloc resection was achieved in all 54 cases,with curative resection of fifty two lesions(96.3%).Twenty three lesions(42.6%)were diagnosed as welldifferentiated adenocarcinoma and the remaining 31lesions(57.4%)were gastric adenoma.All adenocarcinoma lesions were well-differentiated tubular adenocarcinomas and were restricted within the mucosal layer.The sensitivity of reddish color change in AIM-CE is significantly higher than that in WLE(vs tumor size≥2 cm,P=0.016,vs normochromic or reddish surface color,P=0.046,vs depressed macroscopic type,P=0.0030).On the other hand,no significant differences were found in the specificity and accuracy.In univariate analysis,normochromic or reddish surface color in WLE(OR=3.7,95%CI:1.2-12,P=0.022)and reddish change in AIM-CE(OR=14,95%CI:3.8-70,P<0.001)were significantly related to diagnosis of early gastric cancer(EGC).In multivariate analysis,only reddish change in AIM-CE(OR=11,95%CI:2.3-66,P=0.0022)was a significant factor associated with diagnosis of EGC.CONCLUSION:AIM-CE may have potential for screening EGC in patients initially diagnosed as gastric adenoma by forceps biopsy. | Yoshiyasu Kono Ryuta Takenaka Yoshiro Kawahara Hiroyuki Okada Keisuke Hori Seiji Kawano Yasushi Yamasaki Koji Takemoto Takayoshi Miyake Shigeatsu Fujiki Kazuhide Yamamoto | 2014 | World Journal of Gastroenterology2014，20，17： | 12 |
| 6 | Safety trial of high-intensity focused ultrasound therapy for pancreatic cancer显示文摘AIM:To evaluate the safety and clinical application of high-intensity focused ultrasound(HIFU)therapy for unresectable pancreatic cancer(PC).METHODS:Thirty PC patients(16 cases in stage III and 14 cases in stage IV)with visualized pancreatic tumors were admitted for HIFU therapy as an optional local therapy in addition to systemic chemotherapy or chemoradiotherapy.Informed consent was obtained.This study began at the end of 2008 and was approved by the ethics committee of our hospital[Institutional Review Board(IRB):890].The HIFU device used was the FEP-BY02(Yuande Bio-Medical Engineering,Beijing,China).RESULTS:The mean tumor size after HIFU therapy changed to 30.9±1.7 mm from 31.7±1.7 mm at pre-therapy.There were no significant changes in tumor size,mean number of treatment sessions(2.7±0.1 mm),or mean total treatment time(2.4±0.1 h).The rate of symptom relief effect was 66.7%.The effectiveness of primary lesion treatment was as follows:complete response,0;partial response,4;stable disease,22;progressive disease,4.Treatment after HIFU therapy included 2 operations,24 chemotherapy treatments,and 4 best supportive care treatments.Adverse events occurred in 10%of cases,namely pseudocyst formation in 2 cases and mild pancreatitis development in 1.However,no severe adverse events occurred in this study.CONCLUSION:We suggest that HIFU therapy is safe and has the potential to be a new method of combination therapy for PC. | Atsushi Sofuni Fuminori Moriyasu Takatomo Sano Fumihide Itokawa Takayoshi Tsuchiya Toshio Kurihara Kentaro Ishii Syujiro Tsuji Nobuhito Ikeuchi Reina Tanaka Junko Umeda Ryosuke Tonozuka Mitsuyoshi Honjo Shuntaro Mukai Mitsuru Fujita Takao Itoi | 2014 | World Journal of Gastroenterology2014，20，28： | 12 |
| 7 | 中国东北地区兴安落叶松林树干呼吸的研究(英文)显示文摘树干呼吸是森林碳平衡估计中的一个重要项目同时还能够显示树木的活力.对于如何准确估计森林树干呼吸释放CO2总量还存在争论.在本项研究中,2001~2002连续两年在一个33年生的兴安落叶松(Larix gmelini Rupr.)人工林内对树干呼吸进行了测定,同时测定了不同高度树干呼吸、呼吸的日变化、同龄落叶松林内不同个体的树干呼吸以及相关生长状态因子、水分因子和温度因子.结果显示:1)树干上部的呼吸速率在不同季节都高于下部呼吸速率,树干温度的差异能够一定程度上解释这种差异;2)树干呼吸有午间降低的现象,上午的测定结果树干温度与树干呼吸速率紧密相关,而下午则温度依赖性很小,土壤、空气、小枝木质部水势、叶片蒸腾速率和气孔导度都显示下午植物水分亏缺下午较上午严重,呼吸的这种上下午温度相关性的差异可能受这种水分亏缺的影响;3)在同龄林内,树木个体生长状态包括平均生长速率和树冠投影面积与树干呼吸速率有显著相关关系,而树干温度与之相关性很小.幂指数模型和S曲线模型能够产生较好的拟合效果;4)树干呼吸季节变化明显,7月份出现最大值,但同一月份的年间差异较大.自然指数模型能够较好地拟合温度与树干呼吸的季节变化规律.Q10值在2.22(2001年)和3.53(2002年)之间,与以往研究的结果相当.从以上结果可以看出,通过单一的Q10值估计森林树干呼吸总量会产生偏差,要想得到准确的估计,至少应该考虑生长状态的差异和水分状态的差异. | 王文杰 杨逢建 祖元刚 王慧梅 TAKAGI Kentaro SASA Kaichiro KOIKE Takayoshi | 2003 | Acta Botanica Sinica2003，45，12： | 10 |
| 8 | Induced biosyntheses of a novel butyrophenone and two aromatic polyketides in the plant pathogen Stagonospora nodorum显示文摘Fungal aromatic compounds comprise an important and structurally diverse group of secondary metabolites.Several genome sequencing projects revealed many putative biosynthetic gene clusters of fungal aromatic compounds,but many of these genes seem to be silent under typical laboratory culture conditions.To gain access to this untapped reservoir of natural products,we utilized chemical epigenetic modifiers to induce the expression of dormant biosynthetic genes.As a result,the concomitant supplementation of the histone deacetylase inhibitors suberoylanilide hydroxamic acid(500mM)and nicotinamide(50mM)to the culture medium of a fungal pathogen,Stagonospora nodorum,resulted in the isolation of three aromatic compounds(1-3),including a novel natural butyrophenone,(+)-4'-methoxy-(2S)-methylbutyrophenone(1),and two known polyketides,alternariol(2)and(-)-(3R)-mellein methyl ether(3). | Xiao-Long YANG Takayoshi AWAKAWA Toshiyuki WAKIMOTO Ikuro ABE | 2013 | Natural Products and Bioprospecting2013，3，4： | 9 |
| 9 | Irsogladine maleate and rabeprazole in non-erosive reflux disease: A double-blind, placebo-controlled study显示文摘AIM:To evaluate the efficacy of adding irsogladine maleate(IM) to proton-pump inhibitor(PPI) therapy in non-erosive reflux disease(NERD) treatment.METHODS:One hundred patients with NERD were recruited and randomized to receive rabeprazole plus IM(group I) or rabeprazole plus placebo(group P).The efficacy of the treatment was assessed using the Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease(FSSG) and the short form(SF)-36 quality of life questionnaires after four weeks of treatment.We also assessed whether patients with NERD with minimal changes(grade M) had different responses to the therapies compared with patients who did not have minimal changes(grade N).RESULTS:Group I and group P showed significant improvements in their FSSG scores after the treatment(from 17.9 ± 7.9 to 9.0 ± 7.6, and from 17.7 ± 7.3 to 11.2 ± 7.9, respectively, P = 0.0001), but there was no statistically significant difference between the FSSG scores in group I and those in group P.Subgroup analysis showed that significant improvements in the FSSG scores occurred in the patients in group I who had NERD grade N(modified Los Angeles classification)(7.8 ± 7.4 vs 12.5 ± 9.8, P = 0.041).The SF-36 scores for patients with NERD grade N who had received IM and rabeprazole were significantly improved in relation to their vitality and mental health scores.CONCLUSION:The addition of IM to rabeprazole significantly improves gastroesophageal reflux diseasesymptoms and the quality of the lives of patients with NERD grade N. | Takayoshi Suzuki Masashi Matsushima Aya Masui Shingo Tsuda Jin Imai Jun Nakamura Yoko Tsukune Tetsufumi Uchida Hiroki Yuhara Muneki Igarashi Jun Koike Tetsuya Mine | 2015 | World Journal of Gastroenterology2015，21，16： | 8 |
| 10 | 2D Layered Double Hydroxide Nanosheets and Their Derivatives Toward E cient Oxygen Evolution Reaction显示文摘Layered double hydroxides(LDHs)have attracted tremendous research interest in widely spreading applications.Most notably,transition-metal-bearing LDHs are expected to serve as highly active electrocatalysts for oxygen evolution reaction(OER)due to their layered structure combined with versatile com-positions.Furthermore,reducing the thickness of platelet LDH crystals to nanometer or even molecular scale via cleavage or delamination provides an important clue to enhance the activity.In this review,recent progresses on rational design of LDH nanosheets are reviewed,including direct synthesis via traditional coprecipitation,homogeneous precipitation,and newly developed topochemical oxidation as well as chemical exfoliation of parent LDH crystals.In addition,diverse strategies are introduced to modulate their electrochemical activity by tuning the composition of host metal cations and intercalated counter-anions,and incorporating dopants,cavi-ties,and single atoms.In particular,hybridizing LDHs with conductive components or in situ growing them on conductive substrates to produce freestanding electrodes can further enhance their intrinsic catalytic activity.A brief discussion on future research directions and prospects is also summarized. | Xueyi Lu Hairong Xue Hao Gong Mingjun Bai Daiming Tang Renzhi Ma Takayoshi Sasaki | 2020 | Nano-Micro Letters2020，12，7： | 8 |
| 11 | Change in arterial tumor perfusion is an early biomarker of lenvatinib efficacy in patients with unresectable hepatocellular carcinoma显示文摘BACKGROUND Lenvatinib is one of the first-line tyrosine kinase inhibitors used for unresectable hepatocellular carcinoma(HCC). In the present study, we evaluated the potential of early changes in the time-intensity curve(TIC) of arterial phase on contrastenhanced ultrasound(CEUS) as early imaging biomarkers of lenvatinib efficacy.AIM To evaluate the potential of the early changes in the TIC of CEUS as early imaging biomarkers of lenvatinib efficacy in patients with unresectable HCC.METHODS We analyzed 20 consecutive patients with unresectable HCC treated with lenvatinib from March to November 2018. Tumor response at 8 wk was assessed by computed tomography using the modified Response Evaluation Criteria in Solid Tumors(m RECIST). CEUS was performed at baseline before treatment(Day 0) and on day 7(Day 7), and the images were analyzed in the arterial phase for 20 seconds after the contrast agent arrived at the target tumor. Three perfusion parameters were extracted from the TICs: the slope of wash-in(Slope),time to peak(TTP) intensity, and the total area under the curve(AUC) during wash-in. The rate of change in the TIC parameters between Day 0 and Day 7 was compared between treatment responders and non-responders based on m RECIST.RESULTS The rate of change for all TIC parameters showed significant differences between the responders(n = 9) and non-responders(n = 11)(Slope, P = 0.025; TTP, P =0.004; and AUC, P = 0.0003). The area under the receiver operating curve values for slope, TTP, and AUC for the prediction of responders were 0.805, 0.869, and0.939, respectively.CONCLUSION CEUS may be useful for the early prediction of tumor response to lenvatinib therapy in patients with unresectable HCC. | Hidekatsu Kuorda Tamami Abe Yudai Fujiwara Takuya Okamoto Miki Yonezawa Hiroki Sato Kei Endo Takayoshi Oikawa Kei Sawara Yasuhiro Takikawa | 2019 | World Journal of Gastroenterology2019，25，19： | 8 |
| 12 | Endoscopic resection of carcinoid of the minor duodenalpapilla显示文摘We encountered a 65-year-old man with a carcinoid tumor of the minor duodenal papilla. Since he had liver cirrhosis and completely refused surgery, we performed an endoscopic snare papillectomy. The papillectomy was performed successfully without procedure-related complication. The specimens revealed a carcinoid tumor showing that the margin of the tumor was positive. One week later, upper GI endoscopy was performed and the biopsy specimens obtained from base of ulcer showed no neoplastic cells. We performed a duodenoscopy and CT 3, 6 and 18 mo later, and there was no macroscopic or microscopic evidence of tumor recurrence after more than 4 years. | Takao Itoi Atsushi Sofuni Fumihide Itokawa Takayoshi Tsuchiya Toshio Kurihara Fuminori Moriyasu | 2007 | World Journal of Gastroenterology2007，13，27： | 6 |
| 13 | Endoscopic papillary large balloon dilation for removal of bile duct stones显示文摘AIM:To investigate the efficacy and outcomes of endoscopic papillary large balloon dilation(EPLBD)for bile duct stones in a multicenter prospective study.METHODS:Lithotomy by EPLBD was conducted in 124patients with bile duct stones≥13 mm in size or with three or more bile duct stones≥10 mm.After endoscopic sphincterotomy,the papilla was dilated using balloons 12-20 mm in diameter fitting the bile duct diameter.RESULTS:The success rate of first-time lithotomy was 86.3%(107/124)and the final lithotomy success rate was 100%(124/124).Lithotripsy was needed in10 of the 124(13.6%)patients.Adverse events due to the treatment procedure occurred in 6(4.8%)patients,all of which were mild.Performing large balloon dilation after endoscopic sphincterotomy in patients with large stones or multiple stones in the bile duct is considered to ensure the safety of treatment and to reduce the need for lithotripsy.CONCLUSION:It is suggested that treatment by EPLBD for large bile duct stones may be safe and useful. | Yuji Sakai Toshio Tsuyuguchi Yoshiaki Kawaguchi Nobuto Hirata So Nakaji Katsuya Kitamura Shigeru Mikami Tatsuya Fujimoto Masashi Ijima Eishin Kurihara Shuhei Oana Takayoshi Nishino Ryo Tamura Dai Sakamoto Masato Nakamura Takao Nishikawa Harutoshi Sugiyama Hitoshi Yoshida Tetsuya Mine Osamu Yokosuka | 2014 | World Journal of Gastroenterology2014，20，45： | 6 |
| 14 | Does the root to shoot ratio show a hormetic response to stress? An ecological and environmental perspective显示文摘Root/shoot(R/S)ratio is an important index for assessing plant health,and has received increased attention in the last decades as a sensitive indicator of plant stress induced by chemical or physical agents.The R/S ratio has been discussed in the context of ecological theory and its potential importance in ecological succession,where species follow different strategies for above-ground growth for light or below-ground competition for water and nutrients.We present evidence showing the R/S ratio follows a biphasic dose–response relationship under stress,typical of hormesis.The R/S ratio in response to stress has been widely compared among species and ecological succession classes.It is constrained by a variety of factors such as ontogeny.Furthermore,the current literature lacks dose-response studies incorporating the full dose–response continuum,hence limiting scientific understanding and possible valuable application.The data presented provide an important perspective for new-generation studies that can advance current ecological understanding and improve carbon storage estimates by R/S ratio considerations.Hormetic response of the R/S ratio can have an important role in forestry for producing seedlings with desired characteristics to achieve maximum health/productivity and resilience under plantation conditions. | Evgenios Agathokleous Regina G.Belz Mitsutoshi Kitao Takayoshi Koike Edward J.Calabrese | 2019 | Journal of Forestry Research2019，30，5： | 5 |
| 15 | Endoscopic 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 | 2011 | World Journal of Gastrointestinal Endoscopy2011，3，1： | 4 |

| 17 | Prognosis of cancer with branch duct type IPMN of the pancreas显示文摘AIM:To examine the coexistence of metachronous and synchronous cancer in branch duct intraductal papillary mucinous neoplasms of the pancreas (IPMN).METHODS: We reviewed the records of 145 patients with branch duct IPMN between January 1991 and April 2008 and assessed the relationship between IPMN and intraor extra-pancreatic carcinoma and the outcome of IPMN.RESULTS: The mean observation period was 55.9 ± 45.3 mo. Among the 145 patients, the frequency of extra-pancreatic cancer was 29.0%. The frequency of gastric cancer, colon cancer, breast cancer, and pan-creatic cancer were 25.5%, 15.7%, 13.7%, and 9.8%, respectively. Twenty (13.8%) of the patients died. The cause of death was extra-pancreatic carcinoma in 40%,pancreatic cancer in 25%, IPMN per se in 20%, and benign disease in 15% of the patients.CONCLUSION: The prognosis for IPMN depends not on the IPMN per se, but on the presence of intraor extra-pancreatic cancer. | Nobuhito Ikeuchi Takao Itoi Atsushi Sofuni Fumihide Itokawa Takayoshi Tsuchiya Toshio Kurihara Kentaro Ishii Shujiro Tsuji Junko Umeda Fuminori Moriyasu Akihiko Tsuchida Kazuhiko Kasuya | 2010 | World Journal of Gastroenterology2010，16，15： | 3 |
| 18 | Usefulness of contrast-enhanced ultrasonography in determining treatment efficacy and outcome after pancreatic cancer chemotherapy显示文摘AIM:To investigate if contrast-enhanced ultrasonography(CE-US) is useful for determining treatment efficacy and outcome in the early stages of pancreatic cancer chemotherapy by assessing changes in intratumor hemodynamics using CE-US with a contrast agent.METHODS:The subjects were 34 patients with unresectable advanced pancreatic cancer treated by chemotherapy.CE-US was assessed after every treatment(course) completion under the same conditions,and patients were divided into two groups according to the intratumor enhancement pattern:Vascular rich(R) group and vascular poor(P) group.RESULTS:After the second course of treatment,R group in intratumor hemodynamics had 18 patients,and P group had 16 patients.The reduction rates of serum CA19-9 level after chemotherapy which decreased to half or less of the baseline level were 2/15(0.1%) in P group,but 11/16(69%) in R group(P = 0.006).When the mean number of courses of chemotherapy and outcome were compared,P group had a mean number of courses of 4.9(R group,10.2) and mean survival time(MST) of 246 d(R group,402 d),showing that outcome was significantly better in R group(P=0.006).CONCLUSION:CE-US revealed that the change in intratumor blood flow correlated with both serum CA19-9 level and outcome.Patients with serum CA19-9 that decreased to less than half the baseline level,and patients with an abundant intratumor blood flow,had a significantly better outcome.Thus,CE-US is potentially useful for evaluating treatment efficacy and outcome in the early stages of pancreatic cancer chemotherapy. | Atsushi Sofuni Takao Itoi Fumihide Itokawa Takayoshi Tsuchiya Toshio Kurihara Kentaro Ishii Syujiro Tsuji Nobuhito Ikeuchi Fuminori Moriyasu | 2008 | World Journal of Gastroenterology2008，14，47： | 3 |
