Filter by:Rationale: Colorectal cancer is the fourth most common cause of cancer death worldwide, estimated to be responsible for almost 610,000 deaths in 2008. Surgery remains the predominant curative treatment type for colorectal cancer, but has a major impact on the patient's wellbeing by demanding large amounts of metabolic reserves. This can lead to the development of frequently observed and severe postoperative complications. The most important complication after colorectal surgery is anastomotic leakage (AL), which has an incidence of 8-15% in the Netherlands. AL is associated with high short-term mortality rates of up to 40%. Even though many attempts have been made to reduce the incidence of this dreaded complication, none of these interventions have been successful so far. Despite proper patient selection and improvement in surgical techniques, the percentage of AL has been stable for years. Objectives: To investigate whether recently identified patient-specific factors can predict the occurrence of anastomotic leakage in patients undergoing elective surgery for colorectal cancer. Study design: Prospective observational study Study population: Adult colorectal cancer patients undergoing elective surgery. Main study parameters/endpoints: Primary endpoint: AL within 30 days postoperatively Secondary endpoints: Intestinal microbiome in fecal sample, I-FABP, SM22, Calprotectin, C-reactive protein(CRP), Citrullin, complement factors in blood, VOCs in exhaled air, COX-2 & MBL polymorphisms in buccal smear, L3-index & atherosclerosis measurements on CT-scans, SNAQ & MUST scores
The purpose of this study is to exploratorily examine efficacy and safety in the participants with chemotherapy-naïve unresectable, advanced/recurrent colorectal carcinoma of Kirsten rat sarcoma-2 virus (KRAS) wild-type who have been treated with 6 cycles (2 weeks/cycle) of first-line mFOLFOX6 + panitumumab combination therapy and then assigned to two groups i.e., a group receiving 5-FU/LV + panitumumab combination therapy and a group receiving mFOLFOX6 + panitumumab combination therapy.
Background: - T-cells are white blood cells that can find and kill germs and tumors. Cancer can keep T-cells from working. Researchers think a new drug called AMP-224 might help the T-cells in people with cancer. They think the drug might work even better when combined with a certain type of radiation therapy. Objective: - To study the safety and effectiveness of AMP-224 together with 1 or 3 days of stereotactic body radiation therapy (SBRT) directed to the liver. Eligibility: - People age 18 and older with metastatic colorectal cancer. Their cancer must have spread to the liver and not be responding to treatment. Design: - Participants will be screened with a medical history, physical exam, and blood and urine tests. Their tumors will be measured with computerized tomography (CT) scans or magnetic resonance imaging (MRI) of the chest, stomach, and pelvis. They will have an electrocardiogram (ECG) heart test. - Participants will have a small part of their tumor removed by needle (biopsy). - Participants will have 8 study visits over about 10 weeks. - At 1 visit, they will have another tumor biopsy. - At 1 visit, they will get a chemotherapy drug through a vein (intravenous (IV)). - At 6 visits, they will receive AMP-224 through an IV. - At 1 or 3 visits, they will have SBRT. Computed tomography (CT) scans will map the position of their tumor. Radiation beams of different intensities at different angles will be directed to the tumor. - At all visits, some screening procedures may be repeated. - After treatment ends, participants will have 7 follow-up visits over about 5 months. Blood will be drawn. Some screening procedures may be repeated.
This study evaluates the efficacy, safety and tolerability of NER1006 versus MOVIPREP in adult patients requiring bowel cleansing prior to any procedure that requires a clean bowel, using a 2-Day evening/morning Split-Dosing and 1-Day morning only Split-Dosing regimens. Approximately 810 patients will be randomised with the aim of achieving a minimum of 245 patients in each of the 3 groups.
This study evaluates the efficacy, safety and tolerability of NER1006 versus a sodium picosulfate and magnesium salt solution (SP + MS) in adult patients requiring bowel cleansing prior to any procedure that requires a clean bowel, using a Day Before Only Dosing regimen. Approximately 484 patients will be randomised with the aim of achieving a minimum of 220 patients in each of the 2 groups.
This pilot study is designed to test the effects of a high legume (dried bean) diet on hunger and other indicators of health over the course of eight weeks, compared to a more conventional healthy diet.
This study evaluates the efficacy, safety and tolerability of NER1006 versus Trisulfate Solution (TS) in adult patients requiring bowel cleansing prior to any procedure that requires a clean bowel, using a 2-Day evening/morning Split-Dosing regimen. Approximately 540 patients will be randomised with the aim of achieving a minimum of 245 patients in each of the 2 groups.
The primary goal of this Phase 1 study is to characterize the safety and tolerability of MGD007 and establish the maximum tolerated dose (MTD) and schedule of MGD007 administered to patients with metastatic colorectal carcinoma. Pharmacokinetics, pharmacodynamics, and the anti-tumor activity of MGD007 will also be assessed.
This prospective database has two main objectives; - to evaluate the complication rates, 30-day and 90-day mortality from different surgical strategies for unresectable, borderline resectable or initially unresectable liver metastasis from colorectal cancer. - to establish baseline quality parameters for different surgical strategies for unresectable, borderline and initially unresectable colorectal liver metastasis (CRLM) patients.
Adenomas and hyperplastic polyps are polypoid lesion and may occur at any location in the colon. At the present moment, all polyps should be resected endoscopically, although only adenomas, but not hyperplastic polyps have the potential to develop colorectal cancer. This approach enables the conduction of microscopic investigations of the lesions. By today, only the pathological diagnosis can distinguish exactly between adenomas and hyperplastic polyps. Some studies have investigated the value of the socalled optical biopsy method. Optical biopsy means the visual assessment of the polyp and the determination of a diagnosis solely on behalf of optical criteria. This method is conducted in real time during colonoscopy. If it can be shown, that endoscopist using optical biopsy are able to predict histopathological diagnoses of colonic polyps sufficiently this would possibly lead to simplification of diagnostic procedures. For instance, it would be conceivable to resect hyperplastic polyps and small adenomas and discard them without further assessment by a pathologist. Gastroenterological societies demand for a 90 percent accordance between diagnoses set by endoscopists and pathologists as a prerequisite for the implementation of the optical biopsy method. In this study we want to proof that the use of a new narrow-band imaging (NBI) tool (Exera III, Olmpus) is capable to rise accuracy of optically ascertained diagnoses of colonic polyps. NBI is a light filter tool which can be activated by pressing a button at the endoscope. NBI function leads to an endoscopic picture which appears blue and enables endoscopists to better assess surface structures and vascular patterns. In a prospective randomised multicenter setting we plan to conduct colonoscopy in 380 patients. Half of the patients will be examined without use of NBI (control arm). In these cases colonoscopists will assess optical diagnosis of polyps without turning on the NBI tool. If polyps are detected in patients belonging to the intervention arm NBI will be used and optical diagnosis will be determined using the NICE (NBI International Colorectal Endoscopic) classification. All polyps will be resected and send to pathology for further microscopic assessment. After completing the trial we aim to compare accuracy of the optical diagnosis in both groups. Our hypothesis is, that by using the new NBI tool accuracy (accordance between optical and histopathological diagnosis) can be increased from 78% to 90%.
