Active clinical trials for "Colorectal Neoplasms"

The purpose of the study is to find new ways to improve the quality of life of people who have been treated for colon or rectal cancer.

This is a sub-study nested within a previously initiated clinical study (# NCT01946282) focusing on individuals not previously randomized at baseline to the original interventions. The purpose of the sub-study is to evaluate, via a randomized controlled trial design, 3 strategies for promoting screening completion among individuals not up to date with colorectal cancer screening, but assigned to receive screening outreach.

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.

There is no theoretical or practical reason why non-medical personnel such as nurses could not be trained to perform diagnostic colonoscopy with comparable proficiency as medical endoscopists. Nurse endoscopists have been widely accepted in the United Kingdom for the past 15 years as a valuable resource to cope with the increasing demand for endoscopic service, in particular diagnostic colonoscopy for colorectal screening. A pilot study performed in Hong Kong in 2008 has shown that endoscopy nurses can be trained to perform diagnostic endoscopy safely and reliably. This study aims to demonstrate that properly trained nurse endoscopists have a comparable proficiency in performing colonoscopy procedures as their medical counterparts.

Patients are being asked to participate in this study who have colorectal cancer that has come back after initial treatment. The investigators want to improve treatment in patients with this disease. In other types of cancers, it has been possible to improve treatment by studying the gene mutations (called biomarkers) in a patient's cancer and "matching" these to existing cancer therapies or study drugs which target that specific mutation. Colorectal cancers have not been routinely tested in this way. In this study, investigators will determine whether mutational testing can be successfully done on colorectal cancers and how often mutations are detected for which there are existing drugs (or drugs in development). The results will be used to determine if treating physicians use this information in planning subsequent treatment.

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 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.

The main purpose of this study is to examine changes in patient-reported symptoms during the first two cycles of neoadjuvant or adjuvant chemotherapy for non-small cell lung cancer (NSCLC), colorectal cancer (CRC) and breast cancer, among patients who receive standard care plus a proactive nursing intervention relative to patients who receive standard care alone. Interventions to improve symptom management and prevent urgent care needs in both the clinic and hospital for patients receiving chemotherapy with curative intent are needed to enhance the quality of cancer care.

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.
