Trial Identification

Brief Title: Concordance of Imaging and Pathology Diagnosis of Extranodal Tumour Deposits

Official Title: Concordance of Imaging and Pathology Diagnosis of Extranodal Tumour Deposits

Study ID: NCT03303547

Conditions

Adenocarcinoma of the Rectum

Interventions

MRI mapping to guide pathological sampling of extranodal tumour deposits

Study Description

Brief Summary: Any patient with a suspected primary adenocarcinoma of the colon, sigmoid or rectum undergoing surgery are eligible. The date of surgery must be known prior to registration. This trial aims to determine if image mapping techniques can improve the concordance between imaging and pathology detection of tumour deposits. Lymph nodes and tumour deposits will be identified on pre-operative scans and mapped by radiologists then shared with pathologists prior to processing the resected specimen. Patients will be managed at their local hospital with standard follow-up. Patients will be followed up for 5 years.

Detailed Description: A prospective interventional multi-centre study, COMET aims to prove the accuracy of imaging diagnosis of extranodal tumour deposits (TD) and their adverse effect on prognosis of colorectal cancers. The proposed intervention will be additional radiological and pathological assessment and the reporting of supplementary diagnostic information which would not otherwise have been available. This may affect treatment according to local MDT protocols and also affect the provision of prognostic information to patients in subsequent discussions.
