| 1 | Portal vein thrombosis and arterioportal shunts:Effects on tumor response after chemoembolization of hepatocellular carcinoma显示文摘AIM: To evaluate the effect of portal vein thrombosis and arterioportal shunts on local tumor response in advanced cases of unresectable hepatocellular carcinoma treated by transarterial chemoembolization. METHODS: A retrospective study included 39 patients (mean age: 66.4 years, range: 45-79 years, SD: 7) with unresectable hepatocellular carcinoma (HCC) who were treated with repetitive transarterial chemoembolization (TACE) in the period between March 2006 and October 2009. The effect of portal vein thrombosis (PVT) (in 19 out of 39 patients), the presence of arterioportal shunt (APS) (in 7 out of 39), the underlying liver pathology,Child-Pugh score, initial tumor volume, number of tumors and tumor margin definition on imaging were correlated with the local tumor response after TACE. The initial and end therapy local tumor responses were evaluated according to the response evaluation criteria in solid tumors (RECIST) and magnetic resonance imaging volumetric measurements. RESULTS: The treatment protocols were well tolerated by all patients with no major complications. Local tumor response for all patients according to RECIST criteria were partial response in one patient (2.6%), stable disease in 34 patients (87.1%), and progressive disease in 4 patients (10.2%). The MR volumetric measurements showed that the PVT, APS, underlying liver pathology and tumor margin definition were statistically significant prognostic factors for the local tumor response (P = 0.018, P = 0.008, P = 0.034 and P = 0.001, respectively). The overall 6-, 12- and 18-mo survival rates from the initial TACE were 79.5%, 37.5% and 21%, respectively. CONCLUSION: TACE may be exploited safely for palliative tumor control in patients with advanced unresectable HCC; however, tumor response is significantly affected by the presence or absence of PVT and APS. | Thomas J Vogl Nour-Eldin Nour-Eldin Sally Emad-Eldin Nagy NN Naguib Joerg Trojan Hans Ackermann Omar Abdelaziz | 2011 | World Journal of Gastroenterology2011，17，10： | 20 |
| 2 | Transforming growth factor-β1 induces intestinal myofibroblast differentiation and modulates their migration显示文摘AIM:To investigate the effects of transforming growth factorβ1(TGF-β1)on the differentiation of colonic lamina propria fibroblasts(CLPF)into myofibroblasts in vitro. METHODS:Primary CLPF cultures were incubated with TGF-β1 and analyzed for production ofα-smooth muscle actin(α-SMA),fibronectin(FN)and FN isoforms.Migration assays were performed in a modified 48-well Boyden chamber.Levels of total and phosphorylated focal adhesion kinase(FAK)in CLPF were analyzed after induction of migration.RESULTS:Incubation of CLPF with TGF-β1 for 2 d did not changeα-SMA levels,while TGF-β1 treatment for 6 d significantly increasedα-SMA production. Short term incubation(6 h)with TGF-β1 enhanced CLPF migration,while long term treatment(6 d)of CLPF with TGF-β1 reduced migration to 15%-37% compared to untreated cells.FN and FN isoform mRNA expression were increased after short term incubation with TGF-β1(2 d)in contrast to long term incubation with TGF-β1 for 6 d.After induction of migration, TGF-β1-preincubated CLPF showed higher amounts of FN and its isoforms and lower levels of total and phosphorylated FAK than untreated cells. CONCLUSION:Long term incubation of CLPF with TGF-β1 induced differentiation into myofibroblasts with enhancedα-SMA,reduced migratory potential and FAK phosphorylation,and increased FN production.In contrast,short term contact(6 h)of fibroblasts with TGF-β1 induced a dose-dependent increase of cell migration and FAK phosphorylation without induction ofα-SMA production. | Julia Brenmoehl Sandra Nicole Miller Claudia Hofmann Daniela Vogl Werner Falk Jrgen Schlmerich Gerhard Rogler | 2009 | World Journal of Gastroenterology2009，15，12： | 12 |
| 3 | Trans-arterial chemoperfusion for the treatment of liver metastases of breast cancer and colorectal cancer: Clinical results in palliative care patients显示文摘AIM To evaluate the clinical value and efficiency of transarterial chemoperfusion(TACP) in patients with liver metastases from breast cancer(BC) and colorectal cancer(CRC).METHODS We treated 36 patients with liver metastases of BC(n = 19, 19 females) and CRC(n = 17; 8 females, 9 males) with repeated TACP. The treatment interval was 4 wk. TACP was performed with gemcitabine(1000 mg/m2) and mitomycin(10 mg/m2), administered within 1 h after positioning the catheter tip in the hepatic artery. Before treatment, the size, location, tumour volume, vascularization and number of liver tumours were evaluated using magnetic resonance imaging(MRI). Tumour response was evaluated according to the Response Evaluation Criteria in Solid Tumors guidelines.RESULTS TACP using gemcitabine and mitomycin for metastases from CRC and BC was performed without any serious side effects. The follow-up MRI showed a therapeutic response in 84.2% of the BC patients-stable disease 47.4% and partial response 36.8%. A progression was seen in 15.8%.CRC patients showed a therapeutic response in 52.9% of cases. A progression of the disease was documented in 47.1% of the patients with CRC. These data show that TACP in patients with liver metastases of BC leads to a significantly better therapeutic response compared with CRC patients(P = 0.042). The median survival time was 13.2 mo for the BC patients, which is significantly longer than for CRC patients at 9.3 mo(P = 0.001).CONCLUSION TACP for liver metastases of BC appears to be a safe and effective palliative treatment with improved outcomes in comparison to patients with CRC. | Tatjana Gruber-Rouh Marcel Langenbach Nagy NN Naguib Nour-Eldin M Nour-Eldin Thomas J Vogl Stephan Zangos Martin Beeres | 2017 | World Journal of Clinical Oncology2017，8，4： | 7 |
| 4 | Association between facet joint osteoarthritis and the Oswestry Disability Index显示文摘AIM:To investigate the correlation of facet joint osteoarthritis(FJOA) at lumbar levels L4/L5 and L5/S1 and the Oswestry Disability Index(ODI).METHODS:The study involved lumbar MRIs of 591 patients with a mean age of 47.3 years.The MRIs of the lumbar spine were performed on a 1.5 Tesla scanner(Magnetom Avanto,Siemens AG,Erlangen,Germany) using a dedicated receive only spine coil.After initial blinding,each dataset was evaluated by 2 board certified radiologist with more than 5 years experience in musculoskeletal imaging.In total 2364 facet joints were graded.Degenerative changes of the facet joints were evaluated according to the 4-point scale as proposed by Weishaupt et al Functional status was assessed using the ODI.The index is scored from 0 to 100 and interpreted as follows:0%-20%,minimaldisability; 20%-40%,moderate disability; 40%-60%,severe disability; 60%-80%,crippled; 80%-100%,patients are bedbound.Spearman's coefficient of rank correlation was used for statistical analysis,with significance set at P < 0.05.RESULTS:In total 2364 facet joints at lumbar levels L4/5 and L5/S1 were analysed in 591 individuals.FJOA was present in 97%(L4/L5) and 98%(L5/S1).At level L4/5(left/right) 17/15(2.9%/2.5%) were described as grade 0,146/147(24.7%/24.9%) as grade 1,290/302(49.1%/51.1%) as grade 2 and 138/127(23.4%/21.5%) as grade 3.At level L5/S1(left/right) 10/11(1.7%/1.9%) were described as grade 0,136/136(23.0%/23.0%) as grade 1,318/325(53.8%/55.0%) as grade 2 and 127/119(21.5%/20.1%) as grade 3.Regarding the ODI scores,patients' disability had a minimum of 0% and a maximum of 91.11% with an arithmetic mean of 32.77% ± 17.02%.The majority of patients(48.39%) had moderate functional disability(21%-40%).There was no significant correlation between FJOA and ODI on both sides of lumbar level L4/5 and on the left side of lumbar level L5/S1.A weak positive correlation was evaluated between ODI and FJOA on the right side of lumbar level L5/S1.CONCLUSION:The missing correlation of FJOA and ODI confirms our clinical experience that imaging alone is an insufficient approach explaining low back pain.Clinical correlation is imperative for an adequate diagnostic advance in patients with low back pain. | Adel Maataoui Thomas J Vogl Marcus Middendorp Konstantinos Kafchitsas M Fawad Khan | 2014 | World Journal of Radiology2014，6，11： | 6 |
| 5 | Correlation of lumbar lateral recess stenosis in magnetic resonance imaging and clinical symptoms显示文摘AIM To assess the correlation of lateral recess stenosis(LRS) of lumbar segments L4/5 and L5/S1 and the Oswestry Disability Index(ODI).METHODS Nine hundred and twenty-seven patients with history of low back pain were included in this uncontrolled study.On magnetic resonance images(MRI) the lateral recesses(LR) at lumbar levels L4/5 and L5/S1 were evaluated and each nerve root was classified into a 4-point grading scale(Grade 0-3) as normal,not deviated,deviated or compressed.Patient symptoms and disability were assessed using ODI.The Spearman's rank correlation coefficient was used for statistical analysis(P < 0.05).RESULTS Approximately half of the LR revealed stenosis(grade 1-3;52% at level L4/5 and 42% at level L5/S1) with 2.2% and 1.9% respectively reveal a nerve root compression.The ODI score ranged from 0%-91.11% with an arithmetic mean of 34.06% ± 16.89%.We observed a very weak statistically significant positive correlation between ODI and LRS at lumbar levels L4/5 and L5/S1,each bilaterally(L4/5 left:rho < 0.105,P < 0.01;L4/5 right:rho < 0.111,P < 0.01;L5/S1 left:rho 0.128,P < 0.01;L5/S1 right:rho < 0.157,P < 0.001).CONCLUSION Although MRI is the standard imaging tool for diagnosing lumbar spinal stenosis,this study showed only a weak correlation of LRS on MRI and clinical findings.This can be attributed to a number of reasons outlined in this study,underlining that imaging findings alone are not sufficient to establish a reliable diagnosis for patients with LRS. | Annina SplettstoBer M Fawad Khan Bernd Zimmermann Thomas J Vogl Hanns Ackermann Marcus Middendorp Adel Maataoui | 2017 | World Journal of Radiology2017，9，5： | 4 |
| 6 | Magnetic resonance imaging-based interpretation of degenerative changes in the lower lumbar segments and therapeutic consequences显示文摘Intervertebral disc degeneration and facet joint osteoarthritis of the lumbar spine are, among others, wellknown as a cause of low back and lower extremity pain. Together with their secondary disorders they set a big burden on health care systems and economics worldwide. Despite modern imaging modalities, such as magnetic resonance imaging, for a large proportion of patients with low back pain(LBP) it remains difficult to provide a specific diagnosis. The fact that nearly all the lumbar structures are possible sources of LBP, may serve as a possible explanation. Furthermore, our clinical experience confirms, that imaging alone is not a sufficient approach explaining LBP. Here, the Oswestry Disability Index, as the most commonly used measure to quantify disability for LBP, may serve as an easy-toapply questionnaire to evaluate the patient's ability to cope with everyday life. For therapeutic purposes, among the different options, the lumbar facet joint intraarticular injection of corticosteroids in combination with an anaesthetic solution is one of the most frequently performed interventional procedures. Although widely used the clinical benefit of intra-articular steroid injections remains controversial. Therefore, prior to therapy, standardized diagnostic algorithms for an accurate assessment, classification and correlation of degenerative changes of the lumbar spine are needed. | Adel Maataoui Thomas J Vogl M Fawad Khan | 2015 | World Journal of Radiology2015，7，8： | 4 |
