Filter by:Background and study aims Diverticular disease or diverticulosis is a benign disease of the colon. Anatomically this is formation of pockets of bowel wall which protrude through weaknesses in the muscular wall of the colon. The mechanisms leading to their formation remains unclear and is likely a complex interaction of multiple factors. For the majority of people these pockets are incidental findings but for some they can cause symptoms or a segment of colon containing them can become inflamed which is called acute diverticulitis. The main aim of this study is to see if a faecal samples, which will be tested for hidden blood content with a faecal immunochemical test for haemoglobin (FIT), could be used as an alternative to currently used follow-up investigations for patients who have an episode of acute diverticulitis confirmed on a computerised tomography (CT) scan. These are colonoscopy, sigmoidoscopy or a special CT called CT colonoscopy. We will also be doing a test called faecal calprotectin which is a marker of bowel inflammation and an assessment of the microbes that live in the bowel to see if this will provide further insights into the diagnosis and treatment of diverticulitis. Who can participate? All patients 18 or over admitted to a participating hospital with acute diverticulitis confirmed on a CT scan and who planned to have one of the currently used follow-up investigations are eligible. What does the study involve? The study will involve taking three stool (faecal) samples using faecal testing kits posted to participants. One is on their first solid stool after diagnosis (or as early as possible if their first solid stool is before receiving this pack), the others are at 3 weeks after diagnosis and then 6 weeks after diagnosis. What are the possible benefits and risks of participating? There are no risks of participating. FIT testing has been used in cancer screening now for a number of years and we hope to demonstrate that a negative FIT test for patients after acute diverticulitis will be able to exclude a bowel cancer and prevent the majority of future patients having invasive and time consuming tests. There no additional benefit for participants for their current episode, as they will still need to have these tests. Where is the study run from? Royal Surrey County Hospital When is the study starting and how long is it expected to run for? 09/10/2023-30/09/2024 Who is funding the study? The study is being funded by MATTU (Minimal Access Therapy Training Unit), GUTS (GUTS - Fighting Bowel Cancer) and NHIR (National Institute for Health and Care Research). Who is the main contact?

The goal of this study is to investigate the value of MR elastography-based SII as a means of detecting HGP noninvasively in patients with pathology-proven CRLM. MRE will provide a direct measure of tumor-liver adhesion to investigate the relationship between imaging findings and pathophysiological changes in the Liver.
The goal of this clinical trial is to investigate the effectiveness of localized interventions in improving the 5-year survival rate for colorectal cancer patients with ≥10 liver metastases. We aim to answer the following question: Can localized interventions, including surgery and/or ablation and/or stereotactic body radiotherapy (SBRT), enhance the 5-year survival rate compared to palliative chemotherapy alone in patients with ≥10 colorectal liver metastases (CRLM)? Participants in this study, who have achieved disease control through chemotherapy, will undergo either localized interventions (surgery and/or ablation and/or SBRT) or receive palliative chemotherapy alone. Researchers will compare the survival outcomes between these groups to determine the potential benefits of localized interventions for patients with ≥10 CRLM.
The goal of this study is to learn about the epigenetic and genetic regulation (microRNA/mRNA) of colorectal polyps and their evolvement as polyps and to colorectal cancer. Furthermore, the study aims at investigating whether certain epigenetic features, linked to polyps and/or cancer are traceable in blood samples. The main questions the study aims to answer are: 1. Are there specific microRNA/mRNA that are expressed in different types of polyps and cancers and their respective stages? 2. Is microRNA/mRNA expression in polyps and cancer traceable in blood from the same patient? 3. Is the intestinal microbiata correlated with colorectal polyps and cancer and their microRNA/mRNA expression? Type of study: clinical trial Participant population Participants consist of patients undergoing a scheduled colonoscopy where a polyp or cancer is discovered. Healthy controls, with normal colonoscopy findings will be enrolled. Biopsies will be obtained from polyps/cancers and from normal surrounding intestinal mucosa. Biopsies will be obtained from defined intestinal locations from healthy controls. Blood samples will be collected from all participants. Researchers will compare microRNA/mRNA and microbiota in patients with polyps/cancers and their respective stages as well as healthy controls. Comparisons include biopsies and blood samples.
This study is designed to explore the efficacy and safety of anti-PD-1 antibody plus bevacizumab and chemotherapy as first-line treatment for patients with RAS-mutant, microsatellite stable, metastatic colorectal cancer.
The purpose of this study is to evaluate the safety and clinical activity of cemiplimab and the combination of cemiplimab/fianlimab in microsatellite unstable localized or locally advanced colorectal cancer diagnosed in patients age 70 or greater.
In this study, we will first investigate the imaging safety and feasibility of [68Ga]Ga-NOTA-WWH347 and [18F]F-H3RESCA-WWH347 PET/CT in patients with primary and/or metastatic colorectal cancers. The second goal of the study is to preliminarily investigate the diagnostic efficacy (e.g., sensitivity and specificity) of [68Ga]Ga-NOTA-WWH347 and [18F]F-H3RESCA-WWH347 PET/CT in patients with primary and/or metastatic colorectal cancers. This study will provide a new method for the noninvasive target-specific diagnosis of colorectal cancer, and provide an intuitive and clear imaging basis for clinical diagnosis, differential diagnosis and treatment.
In mCRC, response to second-line chemotherapy is limited, and few treatment options are available. It is urgent to design an optimal second-line treatment regimen to improve the response rate and prolong the survival of patients with mCRC. Several studies preliminarily demonstrated that irinotecan, TAS-102 plus bevacizumab regimen could bring promising efficacy with a tolerable safety profile for patients with mCRC as a second-line treatment. This phase I/II study was aimed to determine the recommended phase II dose (RP2D) of the combination of TAS-102, irinotecan, and bevacizumab for future clinical trials in patients with mCRC refractory to both fluoropyrimidine and oxaliplatin and to evaluate its safety and preliminary efficacy.
The SYLMET Trial is a randomized trial to compare simultaneous and two-staged resection of primary colorectal and synchronous liver metastases. This is an investigator-initiated, multicentre, randomized controlled trial to assess complications (primary endpoint), survival, cost-effectiveness, and quality of life (secondary endpoints).This trial will include patients with resectable primary tumour in the colon or upper rectum with less than five liver metastases that is possible to treat with surgical resection and/or ablation (RFA/MWA) at time of evaluation.
This is a prospective, open, single-arm, investigator-initiated clinical study to evaluate the safety and efficacy of intravenous administration of T3011 at different doses in combination with oral regorafenib in the treatment of advanced colorectal cancer.
