Filter by:This project aims to evaluate different approaches to increase colorectal cancer screening among primary care patients at Penn Medicine through a centralized screening outreach program. In a pragmatic trial, we will evaluate different approaches to increase response rate to mailed fecal immunochemical test (FIT) kits among eligible patients, including differentiated packaging, sending text reminders, and personalized reminders.
This is a prospective, open-labelled study to evaluate the efficacy and safety of sequetial transarterial chemoembolization with lipiodol and neoadjuvant chemotherapy in the treatment of initial unresectable colorectal cancer. The progression-free-survival (PFS) will be evaluated as the primary endpoints.
The aim of this study is to assess the feasibility of beta-hydroxybutyrate (BHB) supplementation in individuals who are undergoing a standard-of-care colonoscopy or flexible sigmoidoscopy.
Feedback: during the COVID-19 epidemic, access to operating theaters was restricted so that anesthetists and nurse anesthetists could reinforce the resuscitation workforce. The MEOPA was used as an alternative to sedation, allowing colonoscopies to be carried out, colon polyps and colorectal cancers to be detected.
This is a cross-sectional cohort study based on community population jointly developed by Northern Jiangsu People's Hospital and Shanghai Kunyuan Biological Technology Co., LTD. This study will verify the real world results of polygene methylation detection of colorectal cancer in a large prospective cohort of community population, which is expected to enroll 80,000 permanent residents in Yangzhou city. The preliminary design period of the study is 5 years. In this study, questionnaire survey and polygene methylation test of colorectal cancer were used as the primary screening method, and colonoscopy was used as the further validation examination method to screen colorectal cancer and precancerous lesions. The diagnosis and outcome of all lesions were based on colonoscopy and pathological examination. The evaluation indexes include sensitivity, specificity, detection rate of precancerous lesions and adenoma.
A cardiopulmonary exercise test (CPET) is increasingly used for preoperative risk assessment. Oxygen uptake (VO2) at peak exercise (VO2peak) and VO2 at the ventilatory anaerobic threshold (VO2VAT) are the most commonly used preoperative CPET variables that are associated with postoperative outcomes following colorectal cancer surgery. The aim of this study is to investigate the association between preoperative submaximal and effort-independent CPET variables and postoperative outcomes in colorectal cancer surgery. Specifically, the slope of the relation between minute ventilation and carbon dioxide production (VE/VCO2-slope) and the oxygen uptake efficiency slope (OUES) will be investigated.
Quantitative faecal immunochemical testing (qFIT) is used to test for blood within faeces that cannot always be visible. The presence of blood in the stool has been shown to be a finding where there may be a problem within the large bowel. The test is able to give a numeric value to the blood in the stool and based on this result, further investigations can be planned, or if normal reassurance given. The test is not perfect and minor bowel problems such as haemorrhoids (piles) can give a raised result. However, we have also seen raised results in people who when investigated have a completely normal large bowel. A small degree of 'physiological' non-visible bleeding is likely a normal part of life and for the majority this does not lead to a raised qFIT result. It may be the case in people who have a raised qFIT but then go on to have a completely normal colonoscopy (telescope investigation of the large bowel) that there is a genetic predisposition that increases the amount of normal 'physiological blood' that they produce. This leads to the test being falsely positive and the person undergoing an unnecessary investigation. This study aims to use saliva to test for known genetic markers that effect blood clotting and can increase how much someone bleeds. By comparing the occurrence of these genetic markers in people with a raised qFIT and normal colonoscopy to those with a normal qFIT and normal colonoscopy, we can test this theory. Should this be the case it will help explain why the test can be raised in normal large bowel and could lead to different levels of positivity being used for different people.
Colorectal cancer (CRC) is the third most common cancer and the second leading cause of malignancy-related mortality. Capecitabine has been approved for the treatment of colorectal cancer as first-line therapy. About 50%-68% of patients who take capecitabine develop Hand-foot syndrome. Hand-foot syndrome (HFS) is the most common adverse event of capecitabine-based chemotherapy. Initial symptoms of HFS are dysesthesia, tingling in the palms, fingers, and soles of the feet, and erythema, which may progress to an extremely painful and debilitating condition without prompt management. These symptoms can potentially lead to a worsened quality of life in patients taking capecitabine-based chemotherapy. Moreover, the adverse reaction necessitates dose-reduction or withdrawal of the chemotherapeutic agent. The mechanisms of HFS are still unknown, and there are limited data available on how to prevent them or manage them. However, different hypotheses of capecitabine-induced HFS pathogenesis have been suggested. One of the hypotheses stated that HFS is a kind of inflammation mediated by cyclooxygenase's (COX-2) over expression in palm and feet by capecitabine and its metabolites causing elevation of inflammatory markers as tumor necrosis factor alpha (TNF-α). COX-2 enzyme plays a main role in inflammation and pain. Therefore, celecoxib which is selective (COX-2) inhibitor may have a key role in the HFS treatment plan. A retrospective study and two prospective studies showed that combining capecitabine with celecoxib, a selective COX-2 inhibitor, can significantly reduce capecitabine-related HFS in colorectal cancer patients. Those studies were dependent on HFS grading only without measuring any markers. So, in our study we assess possible protective effect of celecoxib against capecitabine induced HFS and measure inflammatory marker as tumor necrosis factor alpha (TNF-α), oxidative stress marker as Malondialdehyde (MDA), and cyclooxygenase-2 (COX-2) enzyme to show whether capecitabine induced HFS is caused by COX-2 mediated inflammation or not.
The purpose of this research is to determine whether a 16 week, home-based, aerobic and resistance exercise intervention will increase physical activity levels in Black and Hispanic breast, colorectal, or prostate cancer patients. The names of the study interventions involved in this study are: - Supervised aerobic and resistance exercise (SUP) - virtually supervised 16- week aerobic and resistance exercise performed at home via Zoom. - Unsupervised aerobic and resistance exercise (UNSUP) - home-based 16- week aerobic and resistance exercise. - Attention control (AC) - 16-week home-based stretching.
Study ICT-GCC19CART-US-001 (CARAPIA-1) is a Phase 1 study evaluating the safety, tolerability, clinical activity, pharmacokinetics and pharmacodynamics of GCC19CART in subjects with relapsed or refractory metastatic colorectal cancer.
