Active clinical trials for "Colonic Neoplasms"

The investigators will attempt to improve the patient experience before colonoscopy. The investigators will provide an in-office ipad video series and an electronic web guide to help patients learn all the best ways to prepare for colonoscopy. The investigators will then follow the patients who receive this eGuide to colonoscopy and observe whether or not they enjoyed the additional access to information from their providers, and will monitor whether or not they were better prepared for their colonoscopy.

The investigators propose a screening population-based study to systematically evaluate the accuracy and clinical relevance of sDNA testing as a potential alternative to colonoscopy screening. In addition, the investigators propose a genetic epidemiologic study of the relation between colon polyps, an established precursor of colon cancer, and two factors that may influence risk for colon cancer: candidate genes and diet.

Transversus abdominis plane block (TAP block) is a new regional block for abdominal wall.It had been reported the effect of post-operative pain control in minor abdominal surgery, such as inguinal hernia repair and appendectomy. On the other hand, because of the accurate of the pre-operative images, the minimal laparotomy for colon cancer was accomplished. Thus, the purpose of this study is to investigate the effect, such as analgesic effect, hemodynamic stability, and post-operative morphine consumption, of TAP block in minimal laparotomy.

This prospective observational study will evaluate the safety and efficacy of first-line Avastin (bevacizumab) in combination with standard chemotherapy in routine clinical practice in patients with metastatic cancer of the colon and/or rectum. Patients will be followed for the duration of their treatment and a 30-day follow-up after the last dose of study drug.

The purpose of this study is to see whether magnetic resonance (MR) techniques can detect changes caused by chemotherapy in the livers of patients who have been treated for colorectal cancer. Some patients who undergo chemotherapy for colorectal cancer may experience side-effects in their livers. These side effects may influence further treatment options. If this study finds that MR techniques detect changes in the liver due to chemotherapy, then MR methods may eventually be used to help patients and physicians plan further treatment.

RATIONALE: Gathering medical and family history information from patients and family members may help doctors better understand hereditary colorectal cancer and hereditary polyposis syndrome and identify patients at high risk of developing hereditary colorectal cancer. PURPOSE: This research study is collecting information from patients and family members with hereditary colorectal cancer or polyposis syndrome or who are at high risk of developing hereditary colorectal cancer.

Recent studies have shown that survival after a colorectal cancer diagnosis may be affected by a person's activity level and body size. This research says that for colorectal cancer patients, the less active and more obese they are, the more likely they are to have a cancer recurrence or die from their cancer. Chemotherapy has been shown to reduce activity levels, fitness, and body size in some cancer patients. However, it is not known how chemotherapy specific for colon cancer patients affects their activity levels, fitness, and body size. The main goal of our study will be to look at how chemotherapy treatments affect the fitness, activity levels, and body size in colon cancer patients. In order to do this, we will measure these variables before chemotherapy treatments, and at 1 and 6 months following the end of treatment. Our results will show how chemotherapy affects fitness, activity levels, and body size in colon cancer patients and provide data to help in designing an exercise intervention specifically for colon cancer survivors.

CR-POSSUM is one of the most used surgical scores to predict mortality after colorectal surgery. Its main drawback is the requirement of intraoperative variables, whose collection is time-consuming and prevents from obtaining a purely preoperative risk assessment. The primary aim of the study is to develop a new surgical score using preoperative parameters to predict 30-day mortality after colon cancer surgery in the elderly population. The secondary objective is to analyze its efficacy compared to CR-POSSUM.

This comparative effectiveness and descriptive retrospective cohort study will evaluate safety and effectiveness outcomes among commercially insured adults who received a granulocyte colony stimulating factor (G-CSF) biosimilar or originator product during the first cycle of clinical guideline-indicated intermediate or high febrile neutropenia risk chemotherapy.

Our objective is to monitor glomerular filtration rate (GFR)during the perioperative phase of patients undergoing robotic surgery for rectum or large bowel cancers. We will use both a single injection and a continuous infusion of iohexol to measure kidney function for 72 hours after surgery.
