Active clinical trials for "Colorectal Neoplasms"

This study uses the opinions of adults between the ages of 45 and 73 years old to develop and test an interactive nutrition module for use in an existing colorectal cancer screening intervention using virtual human technology. This study will contribute to knowledge of what messages and graphics promote understanding of cancer risk and promote screening.

The Black community has higher rates of colorectal cancer and lower rates of colorectal cancer screenings than whites. Getting screened through FIT testing may help catch colorectal cancer earlier, when it is easier to treat. MSK has created a program to help people who have been FIT tested to also help their peers (family, friends, and colleagues) in their community get FIT tested. The researchers think that training people on peer outreach, such as telling people in your social network about FIT testing and how to get it, may increase the rate of colorectal cancer screening. The purpose of this study is to see if training people on peer outreach increases the number of people who get screened for colorectal cancer through FIT testing.

Recent studies suggest an association of periodontitis with an overall increased cancer risk but also with cancer development in specific anatomic regions, such as in the colon. The gut microbiome in general and specifically Fusobacterium nucleatum have been described to likely affect colorectal cancer (CRC) development. The present project intends to evaluate the possible contribution of the oral cavity as a reservoir for dissemination of F.nucleatum to the colon. Additionally, the gut microbiome and dietary intake will be assessed as possible factors influencing colonization of CRC sites with F. nucleatum and an association of F.nucleatum colonization in the colon with parameters in the saliva and serum will be tested. One-hundred-fifty patients diagnosed with CRC will be included; after cancer diagnosis and before starting cancer treatment a periodontal examination will be done and saliva and serum samples and at the time-point of tumor resection a biopsy of the CRC sites will be collected.

Over-expression of Epidermal Growth Factor Receptor (EGFR) on cells occurs in all aggressive cancers of epithelial origin. Existing tests for monitoring EGFR expression are invasive and not reliable. There needs to be a better way to measure EGFR expression in cancerous tumors to better tailor cancer treatments. This clinical trial aims to demonstrate the feasibility of imaging cancers that express EGFR using 89Zr-DFO-nimotuzumab and Positron Emission Tomography (PET)/Computerized Tomography (CT). By non-invasively imaging the status of EGFR, 89Zr-DFO-nimotuzumab could be used to assist in the identification of patients who are likely to respond to anti-EGFR treatments, including nimotuzumab. The hypothesis is that 89Zr-DFO-nimotuzumab will accumulate to tumors over-expressing EGFR making them visible when imaged with PET/CT. This hypothesis will be tested in this study, along with the optimal imaging time and diagnostic ability.

The current international guidelines for CRC surveillance in IBD recommend as first choice the use of chromoendoscopy, and as an alternative high-definition white light endoscopy (HDWLE) for optimal dysplasia detection, based on data from clinical trials. However, data on the superiority of CE over HDWLE are not consistent in literature. The investigators hypothesize that the better performance of CE in some clinical trials is the result of the associated longer procedural time and the fact that every colon segment is examined twice. Currently, no studies have been published evaluating the dysplastic yield of back-to back HDWLE compared to HDWLE with a single pass or CE in patients with IBD. In the present study, the investigators aim to compare the yield of dysplasia/CRC between 1) regular HDWLE, 2) HDWLE back-to-back, and 3) CE.

To determine amongst spouses of colorectal cancer patients: Screening rates for Colorectal Cancer (CRC) amongst spouses of patients with CRC Barriers to screening based on the Health Belief Model (HBM) Mediators to behaviour change using the transtheoretical model of behavioural change If tailored interventions addressing education, convenience and cost would improve screening rates amongst the spouses

International guidelines recommend deciding the treatment of colorectal lesions based on the estimated histology by endoscopic optical diagnosis. However, the theoretical and practical knowledge on optical diagnosis is not widely expanded The mail goal of this randomised controlled trial is to compare the pooled sensitivity of optical diagnosis for predicting deep submucosal invasion in large non-pedunculated polyps > 20 mm assessed in routine colonoscopies of gastroenterologists attending a e-learning module (intervention group) vs gastroenterologists who do not (control group) The main questions the study aims to answer are: Is the pooled sensitivity of optical diagnosis for predicting deep submucosal invasion in large non-pedunculated polyps assessed in routine colonoscopies increased in those gastroenterologists participating in the e-learning module? Is the pooled diagnostic accuracy of optical diagnosis for predicting deep sm invasion in large non-pedunculated polyps ≥ 20 mm assessed in routine colonoscopies increased in those gastroenterologists participating in the e-learning module? In lesions with submucosal invasion, is the en bloc and complete resection rate (R0) increased in those gastroenterologists participating in the e-learning module? In lesions referred to surgery, is the pooled benign polyps rate decreased in those gastroenterologists participating in the e-learning module? In lesions treated with advanced en bloc procedures (ESD, TAMIS, fullthickness resection), is the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion increased in those gastroenterologists participating in the e-learning module? In lesions treated with piecemeal endoscopic resection, is the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion decreased in those gastroenterologists participating in the e-learning module? Is the diagnostic accuracy for predicting deep submucosal invasion in a test with pictures increased after participating in the e-learning module? The participants (or subjects of study) are gastroenterologists. They will be randomised to do the e-learning course (intervention group) or not (control group). Researchers will compare clinical outcomes of gastroenterologists participating in the e-learning module vs gastroenterologists not participating in the e-learning module to see if: the pooled sensitivity of optical diagnosis for predicting deep submucosal invasion in large non-pedunculated polyps > 20 mm assessed in routine colonoscopies is increased. the pooled diagnostic accuracy of optical diagnosis for predicting deep sm invasion in large non-pedunculated polyps > 20 mm is increased. the en bloc and complete resection rate (R0) is increased in lesions with submucosal invasion. the pooled benign polyps rate decreased in lesions referred to surgery. the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion increased in lesions treated with advanced en bloc procedures (ESD, TAMIS, fullthickness resection). the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion decreased in lesions treated with piecemeal endoscopic resection. the diagnostic accuracy for predicting deep submucosal invasion in a test with pictures after participating is increased.

The purpose of this study is to purpose of this study is to assess if regorafenib is active enough, in terms of 6-month progression-free rate, to warrant further comparative studies in patients with RAS-mutant advanced colorectal cancer who have progressed after first-line oxaliplatin-based chemotherapy plus bevacizumab.

The clinical trial studies how well 11C-glutamine and 18F-FSPG positron emission tomography (PET) imaging works in detecting tumors in patients with metastatic colorectal cancer compared to standard imaging methods such as magnetic resonance imaging (MRI) or computed tomography (CT) scanning.

This study is being done to explore whether acupuncture can improve cognitive difficulties in patients diagnosed with cancer.
