Filter by:Precision prevention holds great promise for colorectal cancer (CRC) screening but has not been adequately explored. A patient's chance of having an advanced colorectal neoplasm (ACN), i.e. a cancer or precancerous polyp in the colon, significantly affects the comparative effectiveness of approved tests. Giving patients a decision aid with information about their risk for ACN, and giving their providers similar information, could help patients and providers decide if colonoscopy or a non-invasive test (such as the fecal immunochemical test) is more appropriate. This could improve decision making and increase uptake of CRC screening, which are the investigative team's long-term goals.
Deep learning technology has an increasing role in medical image applications and, recently, an artificial intelligence device has been developed and commercialized by Medtronic for identification of polyps during colonoscopy (GI-GENIUS). This kind of computer-aided detection (CADe) devices have demonstrated its ability for improving polyp detection rate (PDR) and the adenoma detection rate (ADR). However, this increase in PDR and ADR is mainly made at the expense of small polyps and non advanced adenomas. Colonoscopies after a positive fecal immunochemical test (FIT) could be the scenario with a higher prevalence of advanced lesions which could be the ideal situation for demonstrating if these CADe systems are able also to increase the detection of advanced lesions and which kind of advanced lesions are these systems able to detect. The CADILLAC study will randomize individuals within the population-based Spanish colorectal cancer screening program to receive a colonoscopy where the endoscopist is assisted by the GI-GENIUS device or to receive a standard colonoscopy. If our results are positive, that could suppose a big step forward for CADe devices, in terms of definitive demonstration of being of help for efectively identify also advanced lesions.
Colorectal cancer (CRC) is a major public health problem, with 44,872 new cases per year in France (3rd most common cancer), and 17,684 deaths (2nd cause of death from cancer). Colorectal cancer screening is used to detect early-stage cancers and precancerous lesions (adenomas). Detecting the disease at an early stage enables curative treatment, which is less aggressive and less costly than treatment at an advanced stage. Fecal occult blood screening has proven its effectiveness in the general population, with a 14% to 16% reduction in colorectal cancer mortality, and even a drop in incidence with 2nd generation immunological tests (FIT). In France, organised colorectal cancer screening in the general population has been in place since 2009 and since 2015 has been based on the use of a quantitative immunological test (OC-Sensor®). This test is offered every 2 years to men and women aged between 50 and 74 with an average risk of developing CRC, i.e. nearly 19.7 million people. The disadvantages of the current screening test are: - Insufficient sensitivity, although the FIT is more sensitive than the old guaiac test, its sensitivity is not perfect. - Insufficient specificity: many colonoscopies are performed for nothing. This unjustifiably exposes many patients to endoscopic complications and incurs an unnecessary cost to society. - The participation rate in screening is too low. Colorectal cancer screening participation was 32.1% in 2017/2018, below the European minimum efficiency target of 45% and far below the 71% observed in our Dutch neighbours. Several non-invasive alternatives for colorectal cancer screening are being explored and proposed. Among these techniques, serum protein assay has shown its interest in terms of screening for adenomas and colorectal cancers. The assay of 7 serum proteins (which will be the subject of a patent application in 2020), by ELISA test, is the subject of this study. These results need to be confirmed in a prospective study, with comparison to the gold standard: total colonoscopy. If these results are confirmed, this would make it possible to develop a new non-invasive method of colorectal cancer screening, which would have several advantages over the current test: better sensitivity than the FIT (estimated at about 38% for the detection of advanced adenomas and 88% for colorectal cancers) which would limit the number of false negatives and decrease the number of colorectal cancers discovered at a late stage, a better specificity which would limit the number of false positives and decrease the number of unnecessary colonoscopies, a better participation in the screening test, and a reasonable cost with a technique that can be routinely performed in many centres. Prior to this prospective clinical study, a pre-clinical calibration phase of the test (combined dosage of the 7 candidate proteins) is necessary, which is the subject of the present project.
A Phase 1 dose escalation study to evaluate APR003 in patients with advanced colorectal cancer (CRC) with malignant liver lesions
This study involves a partnership between UTHealth School of Public Health and the Texas 2-1-1 service, which is a helpline connecting low-income and minority callers with a number of needed services. The purpose of this study is to evaluate the effectiveness of a prevention program in which a phone navigator intervention designed to connect 2-1-1 helpline callers to evidence-based screening and prevention services including mammography, Pap test screening, colorectal cancer screening, and HPV vaccination.
Screening programs have been associated with a substantial reduction in colorectal cancer (CRC) mortality through endoscopic resection of preneoplastic lesions and detection of early-stage invasive cancers. In March 2020, the World Health Organization declared as a pandemic the outbreak of coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2. Since then, the SARS-CoV-2 have never stopped spreading, causing an unprecedented situation with highly restrictive considerations to be adopted by the majority of countries worldwide. Health-care facilities have been making an enormous effort to assist patients affected by COVID-19, while adopting measures to maintain a safe environment for patients and healthcare professionals. As a result, the usual workflow in endoscopy departments changed dramatically, leading to an increase in cancelled procedures, probably increasing the future burden of Colorectal Cancer due to delays in diagnosis.
This is a Phase 1b/2, open-label multicenter study evaluating NKTR-255 as a monotherapy and together with cetuximab in patients with head and neck squamous cell carcinoma (HNSCC), colorectal carcinoma (CRC), cutaneous squamous cell carcinoma (cSCC), anal cell carcinoma (ASCC) and cervical cancer. The recommended phase 2 dose of NKTR-255, determined in the dose escalation phase (Phase 1b), will be used to treat patients in Phase 2 of this study.
This phase I study investigates how well a health service program called Witness CARES Services works in increasing access and adherence to colorectal cancer screening in patients who have not undergone a colorectal screening in the past year. Providing patients with navigational and screening services via Witness CARES Services may improve access to and adherence levels of colorectal screening.
This pilot trial evaluates the feasibility of a group diet education program for stage I-IV colorectal cancer survivors. Providing a nutrition education program for colon and rectal cancer survivors may help them have better access to the tools necessary to make healthy food decisions that can impact their cancer outcomes.
Patients aged ≥75 year scheduled for CRC surgery were studied (104 cases) and variables associated with major postoperative complications / mortality were evaluated. The importance of this report is that MPI-score resulted strongly associated with major complications and it was a primary component of an individual prediction model.
