Active clinical trials for "Colorectal Neoplasms"

Introduction: Prevention of colorectal cancer (CRC) is feasible through polypectomy on screening colonoscopy. Patient acceptance remains the main limiting factor for execution. Colon capsule endoscopy (CCE) might be a novel method for large populations. Aims and methods: Patients referred for screening means or lower gastrointestinal complaints were included in this single center pilot study. They underwent preparation and then ingested the capsule (PillCam Colon). Standard colonoscopy was performed the next morning. Significance was defined as polyps >5mm in size. Performance of exams was by independent physician with blinding of results.

The purpose of this study is to investigate whether preoperative TAC is able to improve progression free survival and overall survival in patients receiving liver metastasis resection of colorectal cancer.

The purpose of this study is to investigate whether TAC plus FOLFOX4 or TACE plus folfox4 are able to improve resection rate and overall survival in patients receiving primary colorectal tumor resection than given FOLFOX4 only.

Patients with a history of colorectal cancer and known or suspected liver metastases who are scheduled for contrast-enhanced tomographic imaging will be included in this study. After randomization to either Primovist-enhanced MRI, extracellular contrast media (ECCM)-enhanced MRI or contrast-enhanced (CE)-CT outcomes and resource needs of the diagnostic work-up and treatment will be evaluated for each of the three imaging modalities. Main objectives of the study are to assess the proportion of patients for whom further imaging is required to come to a therapy decision and to evaluate the proportion of patients with intraoperatively modified surgical plans after Primovist-enhanced MRI as compared to ECCM-enhanced MRI and CE-CT.

In a prospective, randomized, controlled study, two methods (water method vs. air method) of performing colonoscopy will be compared in patients undergoing unsedated colonoscopy for CRC screening. The investigators hypothesize that: Study method increases overall cecal intubation with comparable assessment of current experience and patient willingness to repeat future colonoscopy compared with conventional colonoscopy Study method improves bowel preparation and increases polyp pickup rate

Recent national surgical quality guidelines (Surgical Care Improvement Project, National Hospital Inpatient Quality Measures)state that removal of urinary catheters should occur by post-operative day two for all surgical patients. These guidelines exclude neither patients who have undergone rectal surgery nor those with epidural analgesic catheters. The common practice among most colorectal surgeons is to leave urinary catheters in for three to five days for patients who have undergone rectal operations, due to concern for urinary retention. This study aims to explore the outcomes of following the national surgical guidelines for early urinary catheter removal, especially with regards to urinary retention and urinary tract infection.

To compare maintenance chemotherapy with Xeloda to control after best response with first line chemotherapy in advanced colorectal cancer. Main endpoint is progression free survival. A total of 300 patients will be included.

The purpose of this study is to correlate the MRI CT and PET appearances of colorectal liver metastases to pathologic appearance ot better understand the accuracy of imaging to determine tumor size.

The purpose of this study is to determine if a prototype colorectal cancer screening program with the services of a cancer prevention specialist will increase utilization of appropriate colorectal cancer screening tests.

To determine whether the presence of circulating/disseminated tumor cells (CTCs/DTCs) in the blood and bone marrow of colorectal cancer (CRC) patients with localized disease is a negative prognostic factor, and to find correlations with other clinical/pathological disease characteristics.
