BACKGROUND Total mesorectal excision (TME) remains commonplace for T1-2 rectal cancer owing to fear of undertreating a small proportion of patients with node-positive disease. Molecular stratification may predict cancer progression. It could be used to select patients for organ-preserving surgery if specific biomarkers were validated. METHODS Gene(More)
Pyrrolidinedithiocarbamate (PDTC) enhanced the activity of 5-fluorouracil (5-FU) in a colorectal cancer xenograft model. Pyrrolidinedithiocarbamate also reduced gastrointestinal toxicity associated with 5-FU therapy in large but not small bowel. We sought to clarify the basis of this differential enteric toxicity. Apoptosis and mitosis were assessed on a(More)
AIM Strain elastography is a method for recording tissue hardness. Strain in different areas may be compared using strain ratio (SR). The aims of this study were to validate a previously proposed SR cut-off value of 1.25 for differentiating adenocarcinomas from adenomas and to compare the performance of endorectal ultrasonography (ERUS), strain elastography(More)
Tens of thousands of surgical procedures are performed every year in the UK to resolve symptoms of anal bleeding and prolapse caused by haemorrhoids. 1 A steady stream of novel therapeutic approaches may promise more convenient, comfortable, and ultimately eff ective treatment for this common complaint, but innovation is generally associated with increased(More)
