NCT02532803

Brief Summary

Early cancers of the rectum can be removed safely through the anus without subjecting patients to major abdominal surgery in a procedure called TEMS (transanal endoscopic microsurgery). Patients undergoing TEMS can benefit from reduced mortality, impotence, hospital stay and avoiding a stoma that may be associated with pelvic surgery. Currently few of the patients eligible for TEMS are offered it for a variety of reasons that include uncertainties about the risk of leaving residual tumour and the increased risk of subsequent recurrence of cancer within the pelvis. Current UK guidelines state there is no role for imaging in assessing the malignant polyp. Conversely whilst retrospectively reviewing their MRI databank the investigators have found evidence that MRI can accurately judge the depth of these early tumours and thereby potentially identify patients for local excision. The investigators hope to prospectively test their hypothesis that an MRI scan can accurately gauge depth of tumour spread in an unselected group of benign and malignant tumours measuring between 20mm and 50mm in size. The investigators will identify eligible patients awaiting surgery / polypectomy and if they consent to this pilot study participants will undergo an MRI to assess their tumour which assesses safety at all levels of the rectal wall. The accuracy of MRI can then be established by reference to gold standard histopathology. Should MRI prove sensitive and specific then the investigators hope to change national guidelines to mandate MRI to standardise assessment and thereby increase the appropriate use of TEMS in the UK.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients aged over 18 years of age presenting with 20 to 50mm tumours found at flexible sigmoidosocpy /colonoscopy presumed either adenoma or adenocarcinoma.
  • Patients must be able to undergo colonoscopy, adequate bowel preparation, MRI, and surgery if necessary.

You may not qualify if:

  • Patients who are unable to consent, who withhold consent or who withdraw consent will be excluded.
  • Patients will be excluded if they have a contraindication to MRI (e.g. intraocular metal fragments, certain pacemakers, severe claustrophobia).
