Filter by:This phase I/II trial studies the side effects and best dose of nintedanib when given together with capecitabine and to see how well they work in treating patients with colorectal cancer that has not responded to previous treatment (refractory) and has spread to other places in the body (metastatic). Nintedanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It may also block the growth of new blood vessels necessary for tumor growth. Drugs used in chemotherapy, such as capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nintedanib with capecitabine may be a better treatment for colorectal cancer.
This is a multicenter, open-label, phase I study of rSIFN-co (3 times a week via subcutaneous injection for 21 days, with 1 week of washout per cycle).
Identify the best combination of predictive variables that influence ionizing radiation dose and improved image quality through analysis and quantification of PET-CT images in simulators and patients.
Several screening methods exist to screen patients for CRC ranging from invasive (i.e., colonoscopy) to less invasive (i.e., testing the stool for blood). Although choice between screening methods is recommended, patients are not currently offered an unbiased choice and physicians generally recommend only colonoscopy. In this project, the investigators will answer the following questions: 1) Is it feasible to incorporate a DA in the AHP protocol?; 2) Is it feasible to incorporate mailing patients a stool blood test?; 3) Does the DA change CRC screening decision quality, using proxy measures such as knowledge and intent; and 4) Does the DA change the proportion of participants that complete a CRC screening test? To answer these questions the investigators will compare survey responses and CRC test type completed between two AHP CRC surveillance patients groups - those that received usual care versus those that received the DA.
The aim of this study is to compare a new regimen of reduced bowel preparation that does not include low fiber diet with another reduced bowel preparation including low-fiber diet.
This randomized phase II trial studies how well lower-dose compared to standard dose regorafenib works in treating patients with colorectal cancer that has spread from the primary site (place where it started) to other places in the body and does not respond to treatment. Regorafenib may stop the growth of colorectal cancer by blocking the growth of new blood vessels necessary for tumor growth and by blocking some of the enzymes needed for cell growth. It is not yet known whether lower-dose or standard dose regorafenib is more effective in treating patients with colorectal cancer. Clobetasol propionate is a steroid cream that is commonly used to treat a variety of skin conditions and may help prevent hand-foot skin reactions in patients receiving regorafenib.
This study will adapt and test a touch-screen computer program to evaluate cancer risk and provide patient-tailored recommendations for appropriate risk-based testing. This individually tailored intervention delivered right at the point of primary care and just prior to the office visit, can be a helpful and non-obstructive adjunct to clinical care. The primary aim of this project is to test whether a tailored intervention promoting risk-appropriate cancer testing results increases participation compared with a simple non-tailored reminder or no reminder. The trial is designed to determine the extent to which the Cancer Risk Intake System (CRIS) facilitates (1) participation in risk-appropriate colorectal cancer testing, as documented by electronic medical record audit; (2) patient receipt of risk-appropriate colorectal cancer testing recommendations from their physicians, as documented by electronic medical record audit; and (3) changes in patients' intent to participate in risk-appropriate colorectal cancer testing, as documented by patient report. The Family and Community Medicine and General Internal Medicine clinic databases will be used to identify potentially eligible patients with upcoming scheduled appointments. Because physicians will be the unit of random assignment, patients will be coded before study invitation as potential participants in the intervention or the comparison group. A random sample of eligible intervention and comparison group patients will be selected for contact. Identified patients will be mailed letters from the practices and signed by their physicians requesting their participation. The letters will describe a "study of beliefs and practices about cancer prevention and early detection" and will provide a toll-free number to refuse contact. One week after the mailing, patients who have not called to refuse contact will be called by study staff to explain the study, verify eligibility and, if the patient agrees, to arrange an in-person meeting at the clinic 30 minutes prior to their appointment. These calls will be made by trained research assistants who will follow standard calling protocols. After consent, participants will complete the computerized data collection (CRIS) immediately prior to a scheduled primary-care appointment. Intervention group patients and their physicians will receive a printout recommending risk-appropriate colorectal testing and ways to overcome perceived barriers to testing. A member of the research team will hand the patient his or her printout and will deliver the other printout to the physician. Comparison group patients and physicians will receive non-tailored printouts that are simple reminders about testing. The investigators will also establish a true no-contact control by conducting a retrospective chart review for randomly selected patients who did not receive an invitation to participate in the study. This no-contact control will establish a baseline screening rate. The investigators will then conduct analysis with the comparison and intervention group to see if individuals who participate in CRIS have a higher screening rate for colorectal cancer compared to the non-contact group. These additional data will help us better assess study Aims 1 and 2.
The aim of this study is to evaluate Endocuff- assisted colonoscopy in terms of its possible additive contribution in the detection of important lesions, namely polyps and cancers, compared to standard colonoscopy, in a series of patients undergoing back-to-back screening or surveillance colonoscopies in a randomized fashion. Moreover, we aim to assess possible changes regarding post-polypectomy surveillance programs following Endocuff utilization.
This will be a feasibility study to evaluate the role of endocytoscopy in classifying colorectal polyps in vivo. The primary outcomes will be to determine the key endocytoscopy image features of neoplastic and non-neoplastic colorectal polyps. The target population will include adult subjects undergoing screening and surveillance colonoscopies.
Cancer in the colon and rectum represents a global health burden being the most common cancer of the digestive tract. It is the second most common cancer in Denmark and only about half of the patients survive this diagnosis. Thorough characterization of the tumour preoperatively is very important, since it determines if the patient should be treated with chemotherapy before operation and, in the future, which operation would be most suitable for the patient. Research has shown that endoscopic ultrasound (EUS) is superior to a CT-scan, in determining the local growth of the tumour in rectal cancer. Today, a CT-scan is the image modality of choice, and is used in all Danish hospitals when it comes to colon cancer. Hopefully, the investigators can apply EUS in colon cancer patients and thereby alter our diagnostic approach, towards a quicker and safer way to determine which treatment the investigators should offer the patient. With the screening programme for colorectal cancer in Denmark the investigators will find more and more cases of colorectal cancers, especially in the early stages, before symptoms begin. These small tumours put doctors in several dilemmas concerning the strategy of treatment. Even today, the investigators are very reluctant in offering large-scale operations to elderly and fragile patients who have been diagnosed with cancer in the rectum. Instead, local endoscopic operations are performed in selected patients. This approach has not yet been tried in early colonic cancers. However, it might turn out that local, endoscopic surgery will show to be beneficial for patients with colon cancers and maybe even decrease morbidity, mortality and the regenerative period after surgery. The aim of this PhD-project is to investigate the utility of the EUS-method in characterizing tumours in the colon and in investigating the blood flow in the tumour.
