Filter by:Goal is to prospectively determine if stool calprotectin and change in bowel wall thickness and hyperemia, as seen on small bowel ultrasound, at week 0, 14, and 54 can be used to predict response at week 54 to infliximab in pediatric patients with small bowel Crohn's Disease.
The investigators will test the hypothesis that that greater efficacy of anti-tumor necrosis factor (antiTNF) therapy results in reduced need for bowel resection surgery, fewer serious infections, and reduced short term mortality risks, and therefore has a more favorable benefit to harm profile than corticosteroids for inflammatory bowel disease.
The principal research objective is to determine the impact of antibiotic use on the risk of developing long term bowel symptoms after infection with the germ Campylobacter.
The purpose of this study is to determine which early infliximab pharmacokinetic level is most associated with clinical remission at weeks 30 and 54 in pediatric IBD patients.
The MERCURY Study demonstrated the accuracy, feasibility and reproducibility of Magnetic Resonance Imaging (MRI) to stage rectal cancer in a prospective, multidisciplinary, multi-centre study. However, there were differences in patient outcome, dependent upon the position of the tumour in the rectum and its height above the anal verge. Whilst the outcome was excellent for patients who underwent an anterior resection, the outcome, based upon margin involvement and quality of the specimen, was poor for patients who underwent an abdomino-perineal excision for low rectal cancer. It is proposed that accurate MRI staging pre-operatively will allow the correct patients to receive neo-adjuvant chemoradiotherapy (CRT), and also pre-warn the surgeons if the resection margins appear threatened so that the operation can be modified to take this into account. The primary aims of the Low Rectal Cancer Study (MERCURY II) are to assess the rate of CRM positivity rate in low rectal cancer and to assess the difference in global quality of life at two years post surgery in patients according to plane of surgery with or without sphincter preservation.
Extramural venous invasion (EMVI) is the spread of microscopic tumour cells into the veins around the tumour. Rectal cancer treatment has improved greatly over recent years. However, it is important for us to learn as much about the tumours as possible in order to develop newer therapies. Current treatments may benefit from new genetic information relating to the cancer. We hope to identify genetic differences in certain types of rectal cancer which will allow future treatments.
In 2007-2009 the investigators conducted a study to determine the immunogenicity response to HPV vaccine in special risk patients known to be at increased risk of abnormal cervical cytology. The serological response to the vaccine was measured 1 month post the third and final dose (n=70) finding a robust response overall. The aim of this follow-on study is to provide data on the long-term protection offered by the HPV vaccination. The persistence of antibody 5 years post immunisation is unknown and the impact on cervical cytology abnormalities in these special risk groups is important. The study results will help inform national immunisation program recommendations re- booster HPV vaccine doses.
In this study, the investigators want to see if Bacteriotherapy (also referred to as stool transplantation) improves the symptoms and decreases inflammation in children with Inflammatory Bowel Disease (IBD). Examples of IBD are Crohn's Disease and Ulcerative Colitis. Additionally, researchers want to learn whether this experimental therapy delays the need for starting additional medications to treat pediatric IBD.
T cell lymphoma is a heterogenic malignancy with poor outcome. Five-year PFS and OS of the patients recieved classic CHOP regimen(cyclophosphamide,vincristin,doxorubicin and predisone)is less than 30%.High dose intensive chemotherapy doesn`t demonstrate better response. At present, there is no standardized treatment protocol for this kind of lymphoma. Between 1994 and 1998,the Scotland and Newcastle Lymphoma Group prospectively collected data on newly diagnosed patients with enteropathy associated T-cell lymphoma (EATL)in the Northern Region of England and Scotland,which is a rare and aggressive type of peripheral T-cell lymphoma.The novel regimen IVE/MTX (ifosfamide, vincristine, etoposide/methotrexate)-ASCT was piloted for patients eligible for intensive treatment,followed by auto-stem cell transplantation.Five-years PFS and OS were 52% and 60% respectively, significantly improved compared with the historical group treated with anthracycline-based chemotherapy. The encouraged results were extended to the peripherial T cell lymphoma-non specified(PTCL-nos). Past studies suggested pirarubicin was more active to the T cell lymphoma than doxorubicin in vitro based on its high concentration in tumor cells. Clinical data also presented equivalent even superior efficacy of pirarubicin with lower toxicity than doxorubicin. The aim of our study is to compare the response and survival rate of CTOP/ITE/MTX (cyclophosphamide, vincristin,pirarubicin and predisone/ ifosfamide, pirarubicin, etoposide/methotrexate) with those of CHOP regimen,looking forward to its superiority in efficacy and safety for the de novo young patients with T cell lymphoma.
This is a randomised, open-label phase II study comparing GEM-P chemotherapy (experimental arm) with CHOP (control arm) in previously untreated T-cell lymphoma. Eligible patients will be randomised 1:1 between 4-weekly GEM-P or 3-weekly CHOP chemotherapy.
