Filter by:After introducing a nationwide screening program for colorectal cancer (CRC) in Denmark, more cases of early-stage CRC are being detected. Cancers in the earliest stages are often removed locally, either during the diagnostic colonoscopy or through planned minimally invasive surgery. This early detection of cancer, and thereby an improved prognosis, is a positive feature but has also introduced a new clinical dilemma. Is the patient fully cured by the local resection, or do they need further surgery? Whether further surgery is recommended at the Multi-Disciplinary Team (MDT) board meeting depends on the outcome of specific criteria from the histopathological assessment of the locally removed specimen. The presence of these criteria does not, however, translate directly into the presence of residual disease - merely into a theoretically increased risk. In Denmark, after surgery, the fraction of cases with residual disease has been around 15% for many years. In the remaining 85% of cases, local removal alone was curative - and the surgery appears excessive. Investigating blood samples for the presence of circulating tumor DNA (ctDNA) is a new and promising method for cancer detection. The method utilizes that cancer cells release ctDNA into the circulation. ctDNA detected in blood drawn from a patient a few days after local removal of a tumor indicates that residual disease is present and further treatment, such as surgery, is needed. The purpose of this study is to investigate, whether analyses of ctDNA can correctly identify patients with residual disease after local removal of early CRC. If this identification proves accurate, many patients can be spared further surgery.
The purpose of this study is to look at mental health services for adults with depressed mood who were diagnosed with cancer at the age of 65 or older. This study will compare the usual approach for connecting older adults with depressed mood to mental health services with the Open Door for Cancer (OD-C) approach. We will find out if the OD-C approach is practical and useful for cancer patients who participate in the intervention and for providers who see or treat cancer patients.
The goal of this observational study is to screen and differentiate common cancers in participants with or without suspicious lesions. The main question the investigators aim to answer is: Can the developed model, using peripheral blood cell-free DNA sequencing, work well in screening and classifying common cancers especially in the early stages? Participants will undergo the collection of 15~20ml of blood and 1~2 telephone follow-up calls.
The purpose of this study is to determine the safety and feasibility of VGT-309 for the visualization of colorectal tumors in real-time using near-infrared (NIR) fluorescence endoscopy. In addition, signatures of 50+ biomarkers will be evaluated in biopsies using CODEX multi-plexing.
The effect of mailing FIT with the invitation on participation and colonoscopy rates will be evaluated in a randomized controlled trial conducted in the Centre-Val de Loire (CVL) region, involving 64,000 people from the population eligible for colorectal cancer population-based organised screening program (CRC-PBOSP). In the "C" control group, invitations, test delivery and reminders will be carried out in accordance with the CRC-PBOSP rules at the time of the study. Intervention group "B" will evaluate two experimental modes of invitation with direct home mailing of the test: - Method "B1": invitation with test sent to home without prior information letter - Method "B2": information letter followed by invitation with test sent home, designed to optimize participation by first-time subjects (aged 50-51) invited to the CRC-PBOSP for the first time. Ancillary studies will focus 1/ on acceptability of this intervention (qualitative study on a few general practitioners, gastroenterologists and invitees), 2/ on social and geographical inequalities of participation on a subsample of individuals included in EXPEDIT study using ecological indices (EDI, SCALE).
We first collect tumor tissue and adjacent tissue to peform the WES sequencing, then collect blood after postoperative surgery 1, 3. 6, 9, 12, 18, 24 month to detect ctDNA.
Acute colonic diverticulitis is when a part of the colon gets swollen and inflamed. The diagnosis is based on a CT scan, which can show thickening of the colonic walls and infiltration of the diverticula. These changes and the concomitant symptoms can overlap with colorectal cancer (CRC). Therefore, the guidelines suggest that people with diverticulitis should be offered a colonoscopy to ensure, that CRC is not the underlying cause of the changes and symptoms. In Denmark, a lot of people get hospitalized each year due to diverticulitis, and many of them end up having colonoscopies with the purpose of excluding CRC. Currently, there are no methods for guiding colonoscopies following a diverticulitis episode, resulting in numerous unnecessary colonoscopies each year. In the Diverticulitis study, we want to investigate if a simple blood test analyzed for the presence of circulating tumor DNA (ctDNA), can help us decide who needs a colonoscopy. We will collect blood samples from 220 people with diverticulitis and categorize them into ctDNA positive and negative groups. The ctDNA category will be compared to the colonoscopy results to see if there is a correlation between being ctDNA positive and having a CRC diagnosed at the colonoscopy. This study could change clinical practice since we anticipate that ctDNA-guided triaging of diverticulitis patients is a cost-effective strategy for selecting diverticulitis patients needing colonoscopy, ensuring detection of the underlying CRC, and significantly reducing the number of patients undergoing unnecessary colonoscopy.
The goal of this clinical trial is to evaluate the feasibility of remote time-restricted eating (TRE) and mindfulness-based stress reduction (MBSR) interventions and the preliminary effect on EOCRC-related markers. The main question[s] it aims to answer are: - Is it feasible and acceptable to conduct 8-week remote interventions of TRE, MBSR, and combined TRE+MBSR among young adults with excess adiposity and moderate-to-severe perceived stress? - Will participants in the combined group lose more body weight and reduce their stress levels than those in the remaining groups? - Will participants in the combined group experience better body composition changes and improve their cardiometabolic health compared to those in the remaining groups? - Will participants in the combined group exhibit changes in the microbiome compared to those in the remaining groups? Participants will: - Complete 8 weeks of a TRE intervention - Complete 8 weeks of a remote MBSR intervention Researchers will compare 1. TRE alone; 2. MBSR alone; 3. TRE + MBSR; and 4. Control to see if the study is feasible and acceptable; to see if individuals lose body weight; to see if individual stress levels reduce; to see changes in the microbiome.
Colorectal cancer in periooperative period patients (n=60) will be enrolled to this study. Participants will be divided into 4 groups as follows: - group 1 (n=15) will receive 2 capsules (per day) of L. plantarum 299v L. plantarum 299v (Sanprobi IBS®) for 4 weeks - group 2 (n=15) will receive L. plantarum 299v (2 capsules per day) and inulin (4 g) for 4 weeks - group 3 (n=15) will receive placebo (2 capsules per day) and inulin (4 g) for 4 weeks - group 4 (n=15) will receive placebo (2 capsules per day) for 4 weeks
To investigate the relationship between serum chemerin levels of individuals with colorectal cancer and systematic inflammatory response parameters such as C-reactive protein(CRP) and albumin, and to investigate the relationship of these biomarkers with dietary inflammatory index, phytochemical, anthropometric measurements, and dietary inflammatory index, which is calculated with the data obtained from the 24-hour food consumption record and food consumption frequency questionnaire. The aim of this study is to examine the relationships between the index and dietary antioxidant capacity and to compare them with those of healthy individuals.
