Active clinical trials for "Colorectal Neoplasms"

The goal of this research study is to compare how people who are 45-75 years old respond to 3 different versions of a program about screening tests for colorectal cancer. Researchers want to use this study as part of a long-term project to learn the best ways to communicate health information to patients.

The project will use exome sequencing to search for genetic predispositions for familial colorectal cancer (CRC). Except for certain syndromes there is today no good method for identifying individuals with a hereditary high risk for CRC (about 25% of the cases). There is currently no routine screening of the population in Norway for CRC today. Coloscopy, which is the most reliable method, is demanding with respect to resources, it can be painful, and may have complications. This project will attempt to find genetic determinants for identification of individuals with increased risk for familial CRC. Such methods will reduce unnecessary medical examination of unaffected family members, and will make it easier to focus health services on individuals with increased risk. This will represent a significant contribution towards improved health reduced death rate caused by CRC. The project includes research on the ethical aspects, in particular challenges related to how feedback to donors is handled.

Hypothesis of this study is that increased immunity of primary tumor affects the increased number of lymph node retrieved. This study investigates whether immunity-related cytokine expression on primary tumor, colonic mucosa, and serum is associated with the number of lymph node retrieved in colorectal cancer patients.

The objective of this study is to confirm the sensitivity of a stool DNA test for detection of colorectal cancer and pre-cancer. Another objective is to provide anonymous, clinically characterized specimens for a bio-repository for future colorectal cancer-related test development.

The purpose of this study is to prospectively verify if FOLFOXIRI plus bevacizumab as first-line treatment could be considered a promising approach to improve the outcome of BRAF mutant metastatic colorectal cancer patients

This is a prospective, multi-centered study to assess whether urine metabolomics can play a role in the screening of colorectal cancer (CRC). Urine samples will be collected from 1000 patients going through an established CRC screening program, and from a further 500 patients who already have a diagnosis of CRC. Using nuclear magnetic resonance (NMR) spectroscopy, the 1H NMR spectrum of urine samples will be analyzed for specific metabolites, and establish the metabolomic signature of colorectal cancer. The results from metabolomic urinalysis of this screening cohort will be compared with results from colonoscopy, histological descriptions, fecal occult blood testing (FOBT), and fecal immune testing (FIT) to assess the accuracy of urine metabolomics in identifying patients with polyps and malignancies. The urine metabolomic results from the colorectal cancer group will be correlated with operative, histological and clinical staging to define the role of urine metabolomics in assessing colorectal cancer type, location and stage. Additionally approximately 300 urine samples from breast cancer patients and 300 from prostate cancer patients will be collected to validate that the colorectal cancer signature is unique.

To determine whether using a radiolabelled analog of 5-FU, [18F]-5-fluorouracil, for PET/CT imaging can visually demonstrate differential chemotherapy delivery to known tumor sites before and after administration of bevacizumab and determine the optimal timing of bevacizumab administration to maximize the chemotherapy delivery into the tumor for improved cancer treatment.

The purpose of this study is to determine if the degree of agreement between patients and their physicians regarding the "story" of the illness correlates with improved patient symptom control and quality of life. Another goal of the study is to examine the actual language used by patients and physicians in a specific clinical situation.

The primary purpose of this study is to examine the feasibility of collecting pain and other symptom data in outpatient treatment centers across multiple institutions in the Texas Medical Center (TMC). We will also examine the prevalence and severity of cancer-related pain and begin to identify other commonly reported symptoms in outpatient settings. Factors that interfere with management of pain will also be examined. Additionally, the study will explore patient satisfaction with pain management and pain education in outpatient settings. The specific aims of this study include: Primary Objective: -Explore the feasibility of a collaborative effort by oncology nurses to collect pain and symptom data across multiple institutions that care for ambulatory cancer patients in the TMC. Secondary Objectives: Describe the prevalence and severity of pain and other symptoms in persons with breast, colorectal, lung, or prostate cancer who are receiving chemotherapy in the outpatient setting. Describe factors that interfere with adequate pain management in these patients. Examine patient satisfaction with pain management and patient education about pain management.

The purpose of this study is to define new genes for family risks of developing colon cancer.
