Filter by:This research study is about determining how well a Technically Improved Colonoscope from Olympus works in helping the doctor in guiding the scope through the large bowel or colon. When a doctor performs a colonoscopy he guides or inserts the scope from the rectum to the appendix where the small bowel ends and the large bowel begins. There are points during this insertion where there are turns in the colon which can create a loop in the colonoscope. These loops can stretch the colon and create some discomfort and also require special maneuvers by the nurse or patient to help reduce or minimize the loop. Thus, reducing the looping will make it more comfortable for the patient and more efficient for screening for polyps. The purpose of the study is to examine this colonoscope and compare it to the traditional adult colonoscope (Olympus CF-H180). The investigators hypothesis is that this colonoscope will function better with regard to insertion of the scope from the rectum to the cecum.
The objectives of this study are to evaluate the efficacy and tolerability of single-week regimen of irinotecan plus capecitabine in the first-line or second-line treatment of advanced colorectal cancer.
The primary objective of this study is to evaluate the efficacy of Irinotecan in combination with FOLFOX+Bevacizumab versus FOLFOX+Bevacizumab alone in the first-line treatment of patients with metastatic colorectal cancer.
This is a randomized, controlled trial on frail elderly patients (aged 65+) with colorectal cancer. The patients will be randomized into two groups. The control group will receive standard surgical treatment. The intervention group will in addition go through a preoperative comprehensive geriatric assessment. The assessment will include evaluation of co-morbidity and medication, social status, nutritional status, cognition, depression and physical performance. This assessment will form basis of an individualized perioperative intervention. The main aim of the study is to see if the number of postoperative complications in this group can be reduced by a perioperative geriatric intervention. A study of inflammation markers in serum will also be performed, with focus on identifying potential biological frailty markers.
This observational study will evaluate the safety and efficacy of Avastin (bevacizumab) in combination with 5-Fluorouracil based chemotherapy as first-line therapy in Chinese patients with metastatic colorectal cancer. Data will be collected from each patient for up to 3 years.
The purpose of this study is to find out whether METFORMIN decreases protein markers in colorectal tissue. This is a phase IIA study of the pharmacodynamics, safety and tolerability of Metformin in decreasing colorectal mucosa in patients with a history of colorectal adenomas in the past 3 years and a BMI >= 30, with decimals rounded to the nearest whole integer. Metformin as a potential chemopreventive agent for inhibition of the relevant molecular pathways involved in human colorectal carcinogenesis.
A Pilot Trial of Pre-Operative Chemoradiotherapy Using Capecitabine (Xelodaâ), External Beam Radiation and Cetuximab (Erbitux®) Followed by Definitive Surgery in Patients With Localized (Non-Metastatic) Rectal Cancer
We hypothesize that high definition narrow band imaging (NBI) colonoscopy compared to high definition white light colonoscopy will detect an increased number of nonpolypoid (flat and depressed) colorectal neoplasm.
To evaluate the survival benefit of pre-operation chemotherapy of primary tumor tesection (PTR) compared upfront PTR for colorectal cancer (CRC) patients with an asymptomatic resectable primary tumor and synchronous unresectable liver-limited metastases with conversion therapy intent.
This phase I trial will use the combination of irinotecan and BKM120 in patients with advanced colorectal cancer who have failed on or have become intolerant of at least one line of therapy for advanced colorectal cancer and who are candidates for irinotecan therapy.
