Filter by:Multicentric randomised trial. The goal of this clinical research study is to learn if hyperthermic intraperitoneal chemotherapy (HIPEC) will help to decrease the rate of peritoneal carcinomatosis(PC) in patients with high risk of developing PC of colorectal cancer. The safety of this treatment will also be studied.
Most studies of cancer stem cells (CSC) involve the inoculation of cells from human tumors into immunosuppressed mice, preventing an assessment on the immunologic interactions and effects of CSCs. In this study, the investigators examined the vaccination effects produced by CSC-enriched populations from histologically distinct murine tumors after their inoculation into different syngeneic immunocompetent hosts. Enriched CSCs were immunogenic and more effective as an antigen source than unselected tumor cells in inducing protective antitumor immunity.Immune sera from CSC-vaccinated hosts contained high levels of IgG which bound to CSCs, resulting in CSC lysis in the presence of complement.CTLs generated from peripheral blood mononuclear cells or splenocytes harvested from CSC-vaccinated hosts were capable of killing CSCs in vitro. Mechanistic investigations established that CSC-primed antibodies and T cells were capable of selective targeting CSCs and conferring anti-tumor immunity.
The BCCA Oncopanel is a clinical assay being developed to determine genotype status of a prospectively defined set of genes. The purpose of this pilot study is to assess the feasibility and effect on clinical-decision-making of the Oncopanel test. Eligible patients are those with advanced lung, colorectal, melanoma and GIST cancers and patients with diagnosed malignancies being considered for clinical trials.
This randomized phase II trial studies how well irinotecan hydrochloride and cetuximab with or without vemurafenib works in treating patients with colorectal cancer that has spread to nearby tissue or lymph nodes, that has spread to other places in the body, or cannot be removed by surgery. Irinotecan hydrochloride and vemurafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as cetuximab, may block the ability of tumor cells to grow and spread. It is not yet known whether irinotecan hydrochloride and cetuximab are more effective with or without vemurafenib in treating colorectal cancer.
Being diagnosed with cancer confronts patients with a severe disease and they need to learn to deal with a range of new challenges. In order to support patients in the coping process, the website www.krankheitserfahrungen.de provides patients free, reliable information about health issues by sharing peoples' real-life experiences. In our project, the investigators developed a new module on the website for patients with colorectal cancer. The objective of our study is to evaluate if access to the new colorectal cancer module on the website www.krankheitserfahrungen.de increases patient's competence. The investigators will conduct a two-arm randomized controlled trial. Patients affected by colorectal cancer will be randomized into an intervention and a control group: the intervention group will have access for two weeks to the website www.krankheitserfahrungen.de (colorectal cancer module) with cancer patients´ experiences. Patients in the control group will not receive any intervention but will have access to the website for two weeks after completing the study. Patient competence is measured by the self-efficacy component of the German short form of the Cancer Behavior Inventory via an online questionnaire at baseline and after two weeks. A second follow-up assessment will be implemented six weeks after baseline.
We are studying new ways to look for abnormal areas/tissues of the colon during a colonoscopy. The current scopes used for colonoscopies are very good. But if the area doesn't look different to the naked eye, then the scope can't improve on that. We are using special stains or dyes and special scopes to see abnormal areas that are hard to see with the naked eye. The stain or dye is "fluorescent", meaning it glows when special light is used in the colonoscopy scope. You are being asked to let us spray a peptide with a fluorescent tag onto your colon. Peptides are small chains of amino acids (the building blocks that make up proteins) linked together. The peptide we use has 7 amino acids attached to a fluorescent tag ("FIT C" or Fluoresceinisothiocyanate). FITC is used by eye doctors to examine your eyes (the yellow eye drops). We are testing this "fluorescent peptide" to see if it will stick if there are any abnormal areas. If the peptide "sticks", it will "glow" when a special light in the scope is used. In this study, we will apply the fluorescent peptide to your colon by using a spray tube that fits in the colonoscope. This is a phase IB study. This means that although we have applied the peptide to 25 people in our first research study, we still need to learn more about "fluorescent peptide" in people. The Food and Drug Administration (FDA) has not approved this agent, but is allowing us to test it in this study. The main goal of this study is to see if the peptide "glows" well and if we can take pictures of areas that do glow. This is a research study of the peptide and our ability to see it "glow or fluoresce". Being in this study and applying the peptide won't change how our biopsies are taken or how your colonoscopy is done.
The goal of this research study is to compare how people who are 45-75 years old respond to 3 different versions of a program about screening tests for colorectal cancer. Researchers want to use this study as part of a long-term project to learn the best ways to communicate health information to patients.
The objective of this Phase III study is to evaluate the efficacy of nintedanib in patients with metastatic colorectal cancer (mCRC) after failure of previous treatment with standard chemotherapy and biological agents.
The goal of this study is to compare the findings of virtual (CT-colonography) with findings of optical colonoscopies to determine if virtual colonoscopy is suitable for colorectal cancer surveillance.
The purpose if this study is to measure the sensitivity, specificity and accuracy of the Metabiomics Colon Polyp and Colorectal Cancer Assay for the non-invasive detection of colon polyps or colorectal cancer.
