Filter by:This is a simple tissue collection study with no therapeutic intent. Colon tissues will be taken from standard of care procedures. Tissues will be tested for their functions, expression of immune co-signaling molecules and reactions to transduction with recombinant Listeria vectors to assess effects on expression of B7-H1 and cytokines.
This is a monocentric prospective non randomized phase 0 clinical trial targeting patients with colon cancer for whom an upfront surgery has been advised by the pluridisciplinary team.
This is a study to determine how the viscosity (thickness) of an FDA approved gel affects the ease in which endoscopic mucosal resections (EMR) can be performed.
The investigators hypothesize that individuals who receive a personalized 4 week prehabilitation program consisting of exercise and nutrition counselling with post-workout whey protein supplementation will show, before colorectal surgery, improved insulin sensitivity, inflammatory profile, and substrate utilization compared to baseline measures. These results will translate into a higher functional capacity before surgery as demonstrated by an improvement in 6-minute walking test.
We conducted a preliminary study in 2010 using the innovative Illumina GoldenGate (methylation assay) which has enabled us to characterize the level of methylation of 807 potential markers on a series of 200 adenocarcinomas of the colon (C18) and rectosigmoid junction (C19) resected between 1998 and 2001. The results, validated by pyrosequencing, allowed us to establish a panel of 12 markers to assess the level of methylation. The aim of this project is to validate the prognostic value of this panel in a second cohort of patients with adenocarcinomas (stage I to IV) resected between 2002 and 2006 in public and private hospitals (n=685). This study relies on an original collection of surgical specimens of colorectal cancers resected in public and private hospitals among patients resident in the département of Côte-d'Or and followed by the cancer registry of Burgundy. Samples obtained from each cancer and from adjacent normal mucosa are stored in liquid nitrogen in the Ferdinand Cabane Biological Resources Centre(certified S 96900). Annotations are collected by the cancer registry staff from multiple sources (pathologists, gastroenterologists, oncologists and radiotherapists). Pyrosequencing will be used to quantify the level of methylation. The percentage of methylated allele for each marker on cancerous DNA and the ratio of methylated markers to the number of markers analyzed will be determined. The molecular status of MSI, BRAF, KRAS, and PI3K will be taken into consideration. To study the prognosis, relative and relapse free-survival will be calculated. A multivariate relative survival analysis will be performed to determine independent prognostic factors taking into account the characteristics of patients and tumours and epigenetic and molecular alterations. Epigenetic alterations will be described according to age group, sex and subsite. The epigenetic phenotypes will be evaluated according to already known molecular status using logistic regression models.
Despite a robust literature on the benefits of exercise for cancer survivors, most of the research to date falls in two primary areas - aerobic exercise and breast cancer survivors. The focus on aerobic training alone is a concern as resistance training is critical for building the muscle mass necessary to maintain physical function. However, concerns have been raised about the potential for higher than tolerated adverse event rates during resistance training, particularly that which is unsupervised, despite a history of safe use of resistance training in other chronically diseased patient populations. The aim of this pilot study is to demonstrate the feasibility, safety and quality of life benefit of a home-based resistance-training program among colorectal cancer survivors. The investigators will recruit n=30 men and women with stage I-III colon cancer. Participants will be randomized to a home-based exercise intervention that combines aerobic and resistance exercise. Control arm participants will receive a home-based meditation program.
The central hypothesis for this study is that it is safe and feasible to administer intraluminal photodynamic therapy (PDT) to colon cancers by colonoscopy to induce localized inflammatory/immune response. The objective is to demonstrate the feasibility and safety of PDT to colon cancer patients administered before surgery and to characterize the inflammatory/immune response at the tumor site and systemically. The long-term objective of these studies is to modify he natural biology of colorectal cancers and improve patient survival.
The study concerns a survey of attitudes of the public on issues around personal responsibility for health and the use of financial incentives to promote health in the U.S. and Germany. All data are gathered anonymously through online platforms. Two separate professional panel providers are used for access to members of the public. All participants are people who have voluntarily joined a survey panel in the past through an informed consent process and currently serve as panel members.
Background: - The p53 gene normally helps to stop cancer cells from growing. However, when the p53 gene is mutated or damaged, cancer cells may grow unchecked. Researchers have been working on a vaccine that will help the immune system recognize and destroy cells that have the p53 mutation and may be cancerous. - CT-011 is another drug that may help the body's immune system to fight cancer. This drug blocks a chemical found on tumor cells that prevents the immune system from recognizing and destroying them. Research studies have shown that CT-011 slows the growth of tumors. By combining the p53 vaccine and CT-011, researchers hope to slow or stop tumor growth in people whose cancer that has not responded to standard treatments. Objectives: - To test the safety and effectiveness of CT-011 and the p53 genetic vaccine to treat adults with solid tumors that have not responded to standard treatments. Eligibility: - People at least 18 years of age who have solid tumors that have not responded to standard treatments. Design: - Participants will be screened with a medical history and physical exam. They will also have blood tests and tumor imaging studies. - Participants will receive the p53 vaccine as an injection in the arm or thigh. - Two days after receiving the p53 vaccine, those in the study will receive CT-011 as an infusion over about 2 hours. Participants will be monitored during the infusion for any side effects. - The combination of p53 vaccine and CT-011 will be repeated every 3 weeks (one cycle). Treatment will continue as long as the side effects are not severe and the tumor does not grow. - Three weeks after the second dose of p53 vaccine and CT-011, participants will have a full physical exam. They will also have blood tests, and tumor imaging studies. This exam set will be repeated after every two cycles of p53 vaccine and CT-011. - Participants will have regular follow-up visits for up to a year after stopping treatment.
The purpose is to investigate whether polyps that look different at colonoscopy, have formed via different mutations and have different risks of turning into cancer.
