Active clinical trials for "Colorectal Neoplasms"

Microparticles are cellular fragments which are released actively or passively under conditions of inflammation and stress. The impact of surgical operations on quantity and quality of microparticles remains unknown. In this observatory study we investigate quantitative and qualitative aspects of microparticles during cardiac and abdominal operations.

This proposed study will use previous study results to guide the development and evaluation of interventions to improve CRC screening acceptance. The proposed study will evaluate the impact of three interventions to promote CRC screening among siblings in this increased-risk group, who are not currently compliant with CRC screening guidelines: 1) a generic print intervention; 2) a tailored print intervention, and; 3) a tailored print plus tailored telephone counseling intervention.

The purpose of this study is to produce a user-friendly tool- in the form of a questionnaire - to accurately assess early quality of life in patients after abdominal colorectal surgery from the first day after surgery to 6 months after. The study will also compare this questionnaire to the other currently available assessment tools. Patients are invited to participate if they are undergoing abdominal colorectal surgery at University Hospitals of Cleveland.

This study aims to determine whether a test, called the PET scan, may be useful in determining if there are additional locations of cancer not otherwise detectable by other tests. The PET scan is a nuclear medicine imaging study that measures how much radioactive sugar is used by your tumor. The study will compare pictures of the cancer from the PET scan to other x-ray exams, such as a CT scan, as well as to what your doctors find at the time of surgery. If the study results show that the PET scan gives us a good idea of what is happening to the tumor, then it may be useful in deciding which patients with colorectal metastases to the liver should be operated on and what operation should be performed. Additionally, by comparing the results of PET scans with the other studies that will be performed as part of your care, we will try to determine which test best tells us which patient is most likely to benefit from surgery.

Microsatellite instable (MSI) tumors represent almost the 15% of all sporadic colorectal cancers (CRCs). Literature data show that this unique tumor population appears to be poorly responsive to conventional chemotherapy and conversely reveals excellent results to immunotherapy. Our data, as demonstrated by propensity score-matched and win ratio analysis, show that there are no substantial differences between MSI and MSS tumors in early CRC stages treated with surgery alone. On the contrary, stable tumors (MSS) did much better than MSI tumors in advanced CRC stages undergoing conventional adjuvant treatment. Determination of status of DNA mismatch repair system is crucial in high-risk CRCs to optimize treatment.

Detection of progressive disease by neuropeptide Y (NPY) methylation in liquid biopsies in patients with RAS and BRAF wild-type, unresectable, metastatic colorectal cancer receiving first-line treatment FOLFOX/FOLFIRI and panitumumab.

Quality Improvement Project to evaluate how prehabilitation can be incorporated into our colorectal cancer pathway and assess its clinical benefits.

We aim to perform a register-based, observational cohort study to investigate whether it is safe to delay start of treatment with a curative intention after a colorectal cancer diagnosis. Our hypothesis is that delaying start of treatment until 4-8 weeks is as safe as starting treatment within four weeks after a colorectal cancer diagnosis.

Colorectal cancer (CRC) disproportionately affects patients aged 70 years and older. Surgery is the main treatment modality for CRC, but is associated with increased risk of postoperative morbidity, disability and loss of health related quality of life (HRQL).Frailty is an age related state of functional decline and considered to be an important risk factor for adverse outcome in geriatric oncology.Risk models for adverse outcome may be used for treatment decisions in the elderly, but are often not designed to predict patient related outcome measures and do not include frailty characteristics.

This voluntary study is part of a Post-Market-Surveillance plan to proactively collect clinical data for the use of Caiman 5 articulating Maryland in colorectal surgery under daily clinical routine.
