Filter by:This study is a clinical validation of Polydeep, a computer-aided polyp detection (CADe) and characterization (CADx) system. Polydeep Advance 1 is an unicentric prospective diagnostic tests trial with a paired study design. The hypothesis of the study is that Polydeep, a CAD system, is more sensitive than a blinded endoscopists for the detection of colorectal polyps in a high definition colonoscopy.
This study is a clinical validation of PolyDeep, a computer-aided polyp detection (CADe) and characterization (CADx) system. PolyDeep Advance 2 is a multicentric randomized clinical trial with a tandem colonoscopy design. The hypothesis of this study is that Polydeep assisted colonoscopy will reduce the number of missed adenomas in the first withdrawal.
To evaluate the effectiveness and accuracy of the ctDNA dual-target test kit in a large case-control cohort for the detection of colorectal cancer and advanced adenomas.
Patients with colorectal cancer will be recruited to undergo vitamin D supplementation in the peri-operative period. Vitamin D levels (25OHD) will be measured to assess response to supplementation.
The overall goal of this educational program was to increase colorectal cancer screening (CRCS) in men and women who attend Federally Qualified Health Centers (FQHC) in Puerto Rico. FQHCs, referred to in Puerto Rico as "Clínicas 330", are ideal settings to implement innovative approaches to increase CRCS because they serve primarily low-income patients who typically have lower rates of screening. The goal of this study, is to develop and evaluate the impact of a clinic level intervention on increasing CRCS among low-income Puerto Rican men and women aged 50-75, who have either never been screened for colorectal cancer, or are under-screened according recommended guidelines. To evaluate the delivery of the CRCS education program we used a group randomized controlled trial that provided data to determine the effectiveness of the CRC intervention program compared with usual practice (no intervention).
Compare the efficacy and safety of endoscopic resection a full thickness (EFTR) with Full Thickness Resection Device (FTRD) System versus endoscopic submucosal dissection (ESD) in the treatment of Laterally Spreading Tumor Non Granular Type (LST-NG), "no lift" lesions colon and residual / relapse on scars from previous resections endoscopic colon. The dimensional cut off of these lesions is ≤30mm
This prospective study aims to assess the safety and feasibility of lymph node identification using bevacizumab-800CW in patients with cT1-3N0-2 tumours, using peritumoral submucosal injections
This prospective study aims to assess the safety and feasibility of lymph node identification using bevacizumab-800CW in patients with cT1-3N0-2 tumours, using intravenous administration.
Colorectal cancer (CRC) is one of the most common malignant tumors in the world. Surgical resection is the main treatment option for colorectal cancer patients. Surgery may enhance or accelerate tumor recurrence and metastasis. Multiple factors in the tumor microenvironment play important roles in tumor recurrence and metastasis, and modulating the tumor microenvironment can inhibit disease progression. Lidocaine has been found to inhibit tumor growth in animal experiments.
The study involves the planned use of a new microwave-based device during colonoscopy procedures in a small group of patients to assess the preliminary safety of its use and lack of normal clinical practice modification. The device is a final design version, which has been previously tested in several preclinical studies, including: phantom studies, an ex vivo study with human tissues, and an in vivo study with animal model (pig).
