  1. ncbi Elastic scattering spectroscopy accurately detects high grade dysplasia and cancer in Barrett's oesophagus
    L B Lovat
    National Medical Laser Centre, Department of Surgery, Royal Free and University College Medical School, University College London, UK
    Gut 55:1078-83. 2006
    ..The aim of this study was to assess the potential for elastic scattering to detect high grade dysplasia or cancer within Barrett's oesophagus...
  2. ncbi Elastic scattering spectroscopy for detection of dysplasia in Barrett's esophagus
    Laurence Lovat
    National Medical Laser Centre, Institute of Surgical Studies, Royal Free and University College Medical School, 67 73 Riding House Street, London W1W 7EJ, UK
    Gastrointest Endosc Clin N Am 14:507-17, ix. 2004
    ..Even as a point measurement technique or optical biopsy, the technique may become an invaluable tool to endoscopists. This article focuses on elastic scattering spectroscopy (also known as diffuse reflectance spectroscopy)...
  3. ncbi Radiofrequency ablation is effective for the treatment of high-grade dysplasia in Barrett's esophagus after failed photodynamic therapy
    J M Dunn
    National Medical Laser Centre, Department of Surgery, University College London, London, UK
    Endoscopy 43:627-30. 2011
    ..The rate of strictures was 7 % (1/14) and there was a low rate of buried glands (0.5 % follow-up biopsies). These data suggest RFA is both safe and effective for eradication of high-grade dysplasia in patients in whom PDT has failed...

    Br J Cancer 102:1608-17. 2010
    ..Our aim was to determine the accuracy of ICDA vs FC, and evaluate DNA ploidy as a prognostic biomarker after histologically successful treatment with photodynamic therapy (PDT)...
  5. ncbi Comparison of nuclear texture analysis and image cytometric DNA analysis for the assessment of dysplasia in Barrett's oesophagus
    J M Dunn
    Department of Surgery, National Medical Laser Centre, University College London, London, UK
    Br J Cancer 105:1218-23. 2011
    ..We aimed to evaluate NT as a marker of dysplasia in BO and compare with image cytometric DNA analysis (ICM)...

    N G Mathou
    National Medical Laser Centre, Department of Surgery, Royal Free and University College Medical School, UCL, 67-73 Riding House Street, W1W 7EJ, London, UK
    Lasers Med Sci 18:213-8. 2004
    ..Oestrogens were not used in these patients. Our experience shows that long-term remission from blood transfusion is seen in most patients treated with Nd:YAG laser. If bleeding recurs, further laser treatment is usually successful...

    MRC Cancer Cell Unit, Hutchison MRC Research Centre, Hills Road, Cambridge CB2 2XZ, UK
    Neoplasia 6:751-60. 2004
    ..Hence, the increased proliferation seen in Barrett's carcinogenesis is due to abnormal cell cycle entry or exit, rather than a primary abnormality within the cell cycle...
  11. ncbi Cyclin A immunocytology as a risk stratification tool for Barrett's esophagus surveillance
    Pierre Lao-Sirieix
    Medical Research Council Cancer Cell Unit, Medical Research Council Hutchison Research Centre, Hills Road, Cambridge, UK
    Clin Cancer Res 13:659-65. 2007
    ..We hypothesized that cyclin A, which detects a proportion of proliferating cells, would be more specific. Because cytologic sampling has clinical advantages, we also evaluated the efficacy of cyclin A in endoscopic brushing samples...
