Adenoma Colon Polyp clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

LCI (Linked Color Imaging) for Adenoma Detection in the Right Colon

Start date: July 1, 2017
Phase: N/A
Study type: Interventional

Although colonoscopy with polypectomy can prevent up to 80% of colorectal cancers, a significant adenoma miss rate still exists, particularly in the right colon. Optimizing the detection of adenomas and sessile serrated lesions in the right colon is crucial to increase the effectiveness of colonoscopy in colorectal cancer prevention. Last generation Fuji videocolonscopes incorporates the Linked Color Imaging (LCI), a recently developed technology that differentiates the red colour spectrum more effectively than White Light imaging thanks to its optimal pre-process composition of light spectrum and advanced signal processing. The increased colour contrast results in more accurate delineation of abnormal inflammatory or neoplastic findings of colonic mucosa. Preliminary data suggest that LCI may be improve the detection of neoplastic lesion of colon. The investigators performe a tandem prospective study to compare the right colon adenoma miss rates of LCI colonoscopy with those of conventional white light colonoscopy. Therefore participants scheduled for colonoscopy for the assessment of symptoms or for colorectal cancer screening/surveillance receive the examination of the right colon twice, in a back to back fashion, with standard white light (WL) and with LCI. Patients are randomly assigned (1:1), via computer-generated randomisation with block size of 20, to which procedure is done first. The endoscopist are masked to group allocation until immediately before the cecum is reached. Examinations are performed with Fuji videocolonscopes series 700 (EC-760R, EC-760ZP).
