The Utility and Feasibility of Mt-sDNA as a Surveillance Procedure in Colorectal Cancer Survivors

The purpose of this research study is to determine whether testing of stool for a panel of markers will enable us to detect polyps and cancer compared to standard testing.

Five or Ten Year Colonoscopy for 1-2 Non-Advanced Adenomatous Polyps

This trial examines colorectal cancer incidence in participants with 1 to 2 non-advanced adenomas randomized to surveillance colonoscopy at 10 years compared to participants randomized to surveillance colonoscopy at 5 and 10 years.

A Study of Response to Standard Treatment Before Surgery in People With Rectal Cancer

The purpose of the study is to learn more about how the body responds to standard treatment (chemoradiation and chemotherapy). The study will use the results of testing down on participants' blook, tissue, and scans to learn more about how people with rectal cancer respond to chemoradiation and chemotherapy treatment and if it is useful for predicting whether a person's cancer get better, gets worse, or stats the same after treatment.

Biopsy After Radioembolization to Identify Changes in Tumor Cells From the Radiation

The purpose of this study is to study the way radioembolization works by collecting biopsy samples of participants' tumors after the procedure. This research may improve the way that radioembolization is performed, which could help people whose cancer has spread to the liver. The research may also provide information about how tumors respond to radioembolization.

A Study of Tucatinib and Trastuzumab in People With Rectal Cancer

The study researchers believe that a combination of the drugs trastuzumab and tucatinib, given with standard chemotherapy (capecitabine and oxaliplatin/FOLFOX), may help participants with rectal cancer.

Short Course or Long Course Radiotherapy as Total Neoadjuvant Therapy in Locally Advanced Rectal Cancer

This study compares two standard radiotherapy approaches (short-course vs. long-course) given before surgery in patients with locally advanced rectal cancer. The goal is to see which treatment is more effective and better tolerated.

Can We Save the Rectum by Watchful Waiting or TransAnal Surgery Following (chemo)Radiotherapy Versus Total Mesorectal Excision for Early REctal Cancer?

Bowel cancer is the second most common tumour with 41 000 new cases diagnosed annually in the UK, 447 000 across Europe and 1.36 million worldwide; of which one third are located in the rectum. Standard primary radical Total Mesorectal Excision (TME) surgery is an oncologically effective treatment for early stage rectal cancer. However, resection of a low rectal tumour requires a permanent stoma in approximately 10% of cases while many more patients have a temporary stoma, some of which are not reversed. Radical surgery, which evolved to treat locally advanced, symptomatic tumours, may not be the optimal method of treatment for early screen-detected tumours and an organ preserving strategy may generate significantly less morbidity without substantially compromising oncological outcomes. STAR-TREC is a rolling phase II/III study. Phase II aimed to assess the feasibility of a large, multi-centre randomised trial comparing radical surgery versus two contrasting organ saving treatments followed by selective transanal microsurgery. Phase III will evaluate two contrasting organ preservation strategies in terms of organ preservation rates, toxicity (clinician and patient-reported) and Health-Related Quality of Life (HRQoL).

Concordance of Imaging and Pathology Diagnosis of Extranodal Tumour Deposits

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.
