This pilot trial study uses a structural support program for adoption of cancer screening interventions at a rural community-based organization. Rural communities face unique barriers in implementation of evidence-based interventions due to a lack of infrastructure, community capacity, and expertise as academic and research centers are often clustered in urban areas. The support program may help a rural community-based organization select, adapt, and implement cancer prevention and control evidence-based interventions.
Based on the magnesium (Mg) tolerance test, the "gold standard" test of Mg status, more than 50% US participants had Mg deficiency. Observations suggest that the associations between high Mg intake and disease risks may completely differ by the underlying Mg status. Due to major limitations, the Mg tolerance test is not used in conventional clinical practice and rarely used in research. Instead, serum Mg is used for clinical diagnosis. However, serum Mg performs very poorly at identifying those with Mg deficiency. There is a great need to develop implementable, sensitive, and specific biomarkers which can be easily used for identifying people with Mg deficiency. It is known that DNA methylation changes are inducible by environmental exposures, including nutrients, and reversible when the exposure disappears. We propose to identify 5-hmC/5-mC biomarkers for Mg deficiency by a 4- phase EWAS study in the "Personalized Prevention of Colorectal Cancer Trial [PPCCT, R01CA149633; PI, Dai & Yu]" with a total of 240 participants. Mg tolerance test will be used as the gold standard. Finally, using newly identified biomarkers, we will evaluate if 12-week Mg treatment reduces TRPM7 expression, essential in Mg homeostasis and colorectal carcinogenesis, in rectal tissues only among those with Mg deficiency.
This study is a prospective, single-arm, open-label, multi-center, feasibility study to evaluate the safety and efficacy of ColubrisMX ELS System in patients undergoing transanal endoluminal procedures, specifically colorectal Endoscopic Submucosal Dissection.
Serum taurine results in this study showed that, besides CRC biomarkers; it is most attractive, more precious and more accurate early biomarker for early detecting of any malignant change which may led to CRC by other mean it is the most sensitive and more specific tumor marker for CRC. As a result, we can recommend measuring its level regularly with other prognostic tumor biomarkers and screening examination for all people with abdominal and gastrointestinal problems and for precancerous patients as a pre-early biomarker for colorectal carcinoma. So, it needs further studies to confirm that observations on large scale of population as it obvious the small sample size in early stage and lack data due to limited financial resources and it needs more efforts to collect first and precancerous stages patients.
Testicular cancer (TC) survivors treated with platinum-based chemotherapy have an increased risk of colorectal cancer (CRC) (hazard ratio (HR) 3.9 for platinum-containing chemotherapy versus no platinum-containing chemotherapy, 95% confidence interval 1.7-8.9). Colonoscopy screening can reduce CRC incidence and mortality. Given this increased risk of CRC, colonoscopy surveillance should be considered for TC survivors treated with platinum-based chemotherapy. The aim of this study is to evaluate the diagnostic yield of advanced colorectal neoplasia during colonoscopy surveillance in TC survivors treated with platinum-based chemotherapy. The secondary objectives are to determine cost-effectiveness and burden of colonoscopy. Furthermore, the molecular profile of advanced neoplasia will be evaluated to create insight into the carcinogenesis. The effectiveness of fecal immunochemical testing (FIT) will be evaluated with colonoscopy as a reference. Finally, blood plasma platinum-levels will be determined to examine a potential correlation with the outcome of the ccolonoscopy.
This voluntary study is part of a Post-Market-Surveillance plan to proactively collect clinical data for the use of Caiman 5 articulating Maryland in colorectal surgery under daily clinical routine.
This is a Phase II, non-randomized, open-label study to evaluate temozolomide in combination with olaparib in patients with MGMT promoter hypermethylated advanced colorectal cancer.
Background: Gastrointestinal cancer is one of the most common cancers worldwide. Researchers think an unmet need exists to understand and improve treatment options. They want to see if a combination of drugs can help people with metastatic colorectal cancer. Objective: To see if using a combination of Vascular Biogenics (VB)-111 and nivolumab is safe and will cause colorectal tumors to shrink. Eligibility: People ages 18 and older with microsatellite stable colorectal cancer that has spread to the liver Design: Participants must consent to sample collection protocol 11C0112. Participants will be screened with: Blood tests Scans Tumor samples. If these are not available, participants will have a biopsy. Before they start treatment and with every treatment cycle, participants will have: Physical exams Blood tests Heart tests Before they start treatment and every 4 cycles, participants will have computed tomography (CT) or magnetic resonance imaging (MRI) scans. For these, they will lie in a machine that takes pictures of the body. For the MRI, a soft padding or coil will be placed around their head. Participants will have biopsies before they start therapy. They will have them again after 2 6 weeks on study. On day 1 of 14-day cycles, participants will get one or both study drugs by vein. After they finish treatment, participants will have monthly visits for 3 months. They will have a physical exam and blood tests. If participants stop treatment for reasons other than their disease getting worse, they will have scans about every 8 weeks. This will continue until their disease gets worse. Participants will be contacted by phone or email every 6 months. This will continue for life. ...
This is a qualitative interview study that aims to understand treatment burden in individuals who have experienced prostate or colorectal cancer treatment within the past five years. We intend to use patient and caregiver experiences to co-design interventions to optimise cancer aftercare. Treatment burden is the workload of healthcare for patients and the consequences of this workload on patient function. Treatment burden has been associated with negative outcomes in stroke, heart failure, diabetes, and renal failure. Cancer is increasingly becoming a chronic condition, and involves a variety of self-management tasks for patients and their caregivers. In this study investigators will investigate treatment burden in people after prostate and colorectal cancer. Investigators will seek to understand patient and caregiver perceptions about cancer aftercare, and ways that services could be redesigned and improved to reduce treatment burden, and improve patient outcomes. We will undertake a qualitative interview study, recruiting patients from general practices and oncology outpatient clinics who have completed potentially curative treatment for prostate or colorectal cancer, or who are on active surveillance or hormonal therapies for localised or locally advanced prostate cancer. We will purposively sample, to ensure that participants with comorbidities, those from lower socioeconomic groups, and rural dwellers are adequately represented. We will conduct interviews according to a schedule, informed by conceptual models of burden of treatment, Schwarzer's Health Action Process Approach, and Normalisation Process Theory. Interviews will be filmed and/or audio-recorded and transcribed. Framework and thematic analysis will be used to analyse and synthesise the data. Participants will be given the chance to comment on outputs and findings (triangulation). Investigators plan to use the results of this study, and excerpts from video interviews during co-design events, and to create new interventions to optimise aftercare for patients with prostate and colorectal cancer.
