Active clinical trials for "Colorectal Neoplasms"

Regorafenib is a valuable treatment option for metastatic colorectal cancer patients who have progressed after prior standard treatments. Prior progression-free survival data suggest that there could be a distinct subgroup of patients that may benefit from regorafenib. The aim of this study is to identify predictive biomarker of regorafenib in terms of its efficacy.

The purpose of the Ohio Colorectal Cancer Prevention Initiative (OCCPI) is to reduce morbidity and mortality due to colorectal cancer (CRC) in the state of Ohio. By identifying individuals at high-risk for CRC (genetically predisposed) and providing screening recommendations for cancer risk reduction, the OCCPI will understand how to increase length of life and quality of life for those diagnosed with CRC in Ohio, as well as to better prevent CRC in others in Ohio. Participants will have free tumor screening for Lynch syndrome, and may be eligible for free genetic testing and free genetic counseling as part of this study.

The purpose of this study is to explore the effects of cooked navy bean powder or rice bran consumption on the stool microbiome and metabolome of colorectal cancer survivors and healthy adults.

This is a Phase II trial to study the safety and efficacy of IMMU-130. IMMU-130 is composed of a drug attached to an antibody. The drug is the active ingredient in irinotecan which is a common chemotherapy drug used for colorectal cancer. Antibodies are proteins normally made by the immune system. They bind to substances that don't belong in the body to prevent harm to the body. The antibody in this study was designed to bind to a marker located on colorectal cancer tumors. The antibody was originally made from mouse proteins, but was changed in the laboratory to be more like human antibodies. This study will investigate how IMMU-130 acts for the treatment of colorectal cancer. The study is mainly being done to see if IMMU-130 is safe and effective.

This is a behavioral research study to evaluate the effectiveness of a type of health education, lay health worker (LHWs), on increasing the use of a routine health behavior, colorectal cancer (CRC) screening, among Asian Americans, who underutilize such screening. Using quantitative and qualitative methods and a community-based participatory research (CBPR) approach, the project will develop and implement a group randomized controlled trial to evaluate LHW effectiveness in promoting CRC screening among Asian Americans age 50 to 75. The investigators will conduct focus groups and individual interviews with community participants to revise training and survey materials developed in prior projects. The investigators will recruit LHWs to be randomly assigned to the intervention arm and to the comparison arm. The LHWs will each recruit 15 participants from their social network. Intervention LHWs will be taught to teach their participants about CRC screening through 2 outreach sessions and 2 telephone calls aimed at increasing their CRC screening receipt. LHWs and participants in the comparison group will receive a bilingual CRC brochure as well as 2 lectures on healthy nutrition for cardiovascular health delivered by a health educator and an optional post- intervention LHW outreach session on CRC screening. Effectiveness of the intervention will be measured by pre-intervention and post-intervention surveys of community participants' CRC screening behaviors. The investigators will also conduct ethnographic observations of LHWs and their participants during the small group sessions and post- intervention focus groups to understand how such a health education approach may work.

The overall goal of the COACH study is to conduct a comparative effectiveness trial to assess the effectiveness of trained, participant-designated health coaches versus traditional health education efforts on cancer screening among African American older adults. We hypothesize that members of older adults' extended families can be trained to be effective coaches who support them through the cancer control spectrum, i.e., prevention, screening, diagnosis and treatment. This research objective is guided by the theoretical model of the PRECEDE-PROCEED conceptual framework that has been widely adopted in health promotion. The target jurisdictions for this study are Baltimore City (BC) and Prince George's County (PGC), Maryland. The study is anchored in community-based participatory research (CBPR) principles, involving community members in all its phases. The CBPR component is guided by Community Advisory Groups (CAGs) representing key stakeholders in the two jurisdictions. The CAGs are essential in determining the questions included in data collection instruments, mechanisms of recruitment, interpretation of findings, and dissemination of results within the target communities.

80 - 90 % of the patients treated with anti-EGFR antibodies (panitumumab or cetuximab) experience skin toxicity, mostly acne like skin rash. A standardized treatment of skin rash is neither established as standard arm for clinical trials nor as guideline for the treatment of skin toxicity in clinical practice. While an improvement of QoL has been demonstrated for panitumumab and cetuximab in comparison to best supportive care the data basis for patient related outcomes regarding skin toxicity deriving from randomized trials is still small. Recent surveys among German oncologist revealed that physicians are reluctant to use oral antibiotics as preemptive treatment . Only 19 out of 110 oncologists stated that they are thinking about using preemptive treatment in patients with acne-like skin rash. Thus, in the present trial two main questions will be addressed: (i) Can preemptive treatment with oral doxycycline be replaced by a sequential skin treatment strategy (i.e. local treatment with erythromycin followed by doxycycline in case of inefficacy = development of acne) without compromising treatment efficacy of skin toxicity treatment? (ii) Comparison of general and skin related QoL between both treatment arms.

To determine whether colonic bubbles associated with CT colonography performed with iohexol for fecal/fluid tagging could be reduced by adding simethicone to the standard cathartic preparation.

Screening for ColoRectal Cancer (CRC) is widely recommended because of compelling evidence that it reduces mortality from CRC and that it's cost-effective. In France, there is a national CRC screening programme inviting people aged 50-74 years by mail to consult their General Practitioner (GP) for a free on charge Faecal Occult Blood test deliverance every two years. Participation is a key factor for the screening programs success. High levels of screening uptake and the continued participation to regular screening must be achieved and maintained in the targeted population if the enormous potential of CRC screening is to be realised. Screening rates of various international programs vary widely (20-52%) and the participation is insufficient in the most settings. Therefore, a better understanding of facilitating and hindering factors of patient participation can guide interventions to improve CRC screening rates. They include patients and physicians' factors. One issue is about GPs practice. GP involvement has been shown to improve the participation in the CRC screening. This study aims to assess the effectiveness of an intervention targeting GPs to increase patient participation in the CRC screening. Volunteer GPs will be randomly assigned to either the intervention group or to usual care (control group) and they will be followed one year. The intervention consists in providing every four months to the experimental group a list of their patients who are eligible but did not proceed yet to the screening. In both groups, patient participation in the screening will be measured at the end of the study.

The investigators hypothesize that high definition colonoscopy with close focus narrow band imaging features has a high diagnostic accuracy for colorectal polyp histology, and can replace formal pathologic assessment in cases of high diagnostic confidence.
