Active clinical trials for "Colorectal Neoplasms"

Colorectal cancer (CRC) is an important United Kingdom healthcare issue affecting 1 in 20 individuals, half of whom will die from the disease. Late presentation of CRC has a poor prognosis, whereas excellent cure rates (>95%) are seen in those who present early. Accurate and early diagnosis of CRC is therefore crucial. In most patients this is achieved via colonoscopy, a camera test which is widely available and allows tissue samples to be taken of any abnormalities seen during the procedure. However, a non-invasive alternative is Computed Tomography Colonography (CTC) which uses X-rays to produce images of the large bowel which are then interpreted by Radiologists. CTC has high sensitivity for the diagnosis of CRC (comparable to colonoscopy) and the cancer precursor - adenomatous polyps. Unlike colonoscopy, however, there is no accreditation process for CTC and there is no infrastructure to ensure that all reporting Radiologists are able to do so adequately and, as a result, there is a wide range of diagnostic accuracy. There are no universally-accepted standards to monitor quality or assess diagnostic performance, partly because we do not know what the quality markers are and there is currently no system to quantify them. Overall, this contributes to low cancer detection rates, missed cancers and inequity for patients across the National Health Service (NHS). This study aims to assess the impact of a structured training programme with assessment and feedback on NHS radiologist performance. If the impact is positive and results in significantly improved performance, then such a scheme could be adopted into an accreditation programme for CTC in the English Bowel Cancer Screening Programme (BCSP).

Colorectal cancer is the third most common cancer diagnosed in both men and women in the United States. The death rate from this disease, however, has been decreasing over the last 20 years. Early detection and removal of pre-malignant polyps is considered to be at the core of this change. At the same time, polyp detection is highly dependent on an adequate bowel preparation. Froehlich, et al., found that poor bowel preparation is associated with longer colonoscopy times, more difficult procedures and a higher rate of incomplete procedures(2). Although a Clear Liquid Diet is usually the prescribed diet in most bowel preparation regimes, several studies have shown similar results with less restrictive diets. Based on the hypothesis that a Full Liquid Diet(FLD) is not inferior to a Clear Liquid Diet(CLD), investigators plan to conduct a prospective, randomized trial, in order to compare these dietary interventions. The investigators and endoscopists will be blinded to patient's diet group. Researchers aim to investigate if diet liberalization to a Full Liquid Diet(FLD) is associated with similar bowel cleansing as compared with a Clear Liquid Diet(CLD). Investigators will compare the performance of these dietary interventions regarding adenoma detection rates(ADR), time to cecal intubation(TCI), and colonoscope withdrawal time. In addition, the investigators want to assess whether patient's Compliance and Satisfaction is similar or superior in the experimental group vs the control group.

This prospective, multicenter, observational study will investigate the effectiveness and safety of bevacizumab in routine clinical practice in participants with metastatic CRC. Participants are to have initiated first-line treatment with fluoropyrimidine-based doublet chemotherapy plus bevacizumab according to the bevacizumab Summary of Product Characteristics (SmPC).

The purpose of the study is to investigate the safety and effectiveness of Stivarga in patients with metastatic colorectal carcinoma in routine use in Germany. The study is purely observational, only data from routine treatment are to be collected. The treatment and treatment conditions are solely at discretion of the treating physician.

Folic acid (FA) and its derivatives (folate) which play a role in nucleotide synthesis and methylation reactions as well as calcium and vitamin D are assumed to be effective in the prevention of colorectal polyps and Colorectal cancer (CRC). The aim of this study is to investigate the roles of FA as well as calcium and vitamin D in the prevention of CRC.

The long-term goal of this research is to develop new tools to guide patients, caregivers, and clinicians in making individualized decisions regarding colorectal cancer (CRC) surveillance. As part of a Patient-Centered Outcomes Research Institute-funded contract, investigator will analyze surveillance data to determine the effectiveness of CRC surveillance and recurrence risk taking into account different patient and tumor characteristics; identify key issues about CRC surveillance important to patients, caregivers, and clinicians; and integrate the recurrence risk and patient priorities into a patient-centered, risk stratified surveillance strategy by creating an interactive decision aid for use by patients and clinicians. This protocol addresses a formative step in the creation of the interactive decision aid where patients' information needs and preferences are assessed regarding decisions about surveillance. The specific aims of this protocol are: Phase 1 - To interview patients and their caregivers to determine their concerns, preferences and key priorities regarding surveillance after curative resection of colorectal cancer, and Phase 2 - To refine the key priorities identified in phase 1 through focus groups and surveys with patients and caregivers.

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 efficacy and safety of panitumumab (Vectibix) in the routine clinical setting will be studied. Specifically, information will be collected on the following as events of interest: skin disorders, interstitial lung disease, infusion reactions, electrolyte abnormalities, and cardiac disorders.

The abundant results from this trial will be helpful for assessing the feasibility of increasing stool sampling and shortening screening interval in population setting for lower and upper gastrointestinal tract lesions, their long-term effects, and the respective cost-effectiveness. The study will evaluate the value of population-based screen and treatment for H. pylori infection when the HPSA is combined with the FIT.

This is a multicenter, post-authorization observational with prospective follow-up (EPA-SP) study. Will be involved 137 metastatic breast cancer patients or metastatic colorectal cancer. The hypertension will be evaluated as a predictor of efficacy of bevacizumab associated with chemotherapy, in terms of progression-free survival (PFS) (Main endpoint). The duration of the study will be approximately 42 months.
