Filter by: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.
Data on disease recurrence was collected for all primary colon cancer patients diagnosed in the Netherlands over the first six months of 2015. Three-year cumulative incidence, risk factors, treatment and three-year OS of locoregionally recurrent colon cancer were determined.
This project aims to evaluate different approaches to increase colorectal cancer screening among primary care patients at Penn Medicine through a centralized screening outreach program. In a pragmatic trial, we will evaluate different approaches to increase response rate to mailed fecal immunochemical test (FIT) kits among eligible patients, including differentiated packaging, sending text reminders, and personalized reminders.
This is an observational retrospective cohort study to determine metachronous peritoneal carcinomatosis in a specific subgroup of colon cancer patients, those with a final pathologic exam corresponding to pT4 tumors. Based on a sample size calculation of 1152 patients, a retrospective review of a three year period of every participant hospitals, 50 in total, of different characteristics, was stablished. Demographic, clinical, operative, histologic and oncologic follow-up variables were recorded.
A randomised controlled feasibility study to compare two surgery techniques in the formation of a permanent end colostomy; the trans-peritoneal(TP) technique - currently, the most commonly used technique and the investigational extra-peritoneal(EP) technique, which has been reported in small studies to reduce the risk of parastomal hernia . This feasibility study will primarily aim to determine the feasibility viability of progression to a full multi-centre trial and test study design acceptability for participants. Participants will be asked to consent to be randomised to either the TP or EP procedure during surgery. Following surgery, participants will be followed up to a maximum of 12 months and asked to complete quality of life questionnaires (EQ5D and Colostomy Impact Score). Participant data will also be accessed by research teams at site to collect data on stoma appliance use and complications.
The purpose of this study is to identify patients who may be eligible to participate in a separate Phase 2/3 treatment study evaluating an individualized neoantigen vaccine GRANITE for first line (1L) maintenance treatment of metastatic, microsatellite-sable colorectal cancer (MSS-CRC) sponsored by Gritstone bio. This may include the manufacturing of an individualized vaccine, which involves neoantigen prediction and generating a vaccine targeting neoantigens.
This phase Ib trial studies the safety and side effects of a vaccine (PolyPEPI1018 vaccine) in combination with TAS-102 in treating patients with colorectal that has spread to other parts of the body (metastatic). PolyPEPI1018 peptide vaccine is used to immunize against proteins present on the surface of tumor cells. This vaccine can activate the body's immune cells, called T cells. T cells fight infections and can also kill cancer cells. TAS-102 may help block the formation of growths that may become cancer. Giving PolyPEPI1018 and TAS-102 may kill more tumor cells in patients with metastatic colorectal cancer.
Right sided hemicolectomy is the standard type of operation for cancers in the caecum, the ascending colon, proximal transverse colon.The aim of this study was to assess the safety and feasibility of combined medial and caudal approach in performing right hemicolectomy and to compare outcome between laparoscopic and open surgery in right colon cancer.
The approach of anastomosis in laparoscopic resection of transverse colon cancer (TCC) has rarely been discussed. This study aims to compare the resection margin of TCC with extracorporeal anastomosis (ECA) versus intracorporeal anastomosis (ICA). Patients who underwent laparoscopic resection of TCC from August 2019 to July 2021 in 13 participating centers are included in this study. According to the approach of anastomosis, patients are divided into two groups, ECA group and ICA group respectively. The clinical characteristics, the perioperative outcomes and the pathological results (especially the length of resection margin) are compared between the two groups. The length of two-sided resection margins (long margin, short margin) are measured on formalin-fixed specimens and those with short margin less than 4.0 cm are defined as unqualified specimens.
Colorectal cancer (CRC) is a leading cause of cancer-related morbidity and mortality worldwide, with rates of CRC predicted to increase. Colonoscopy is currently the gold standard of screening for CRC. Artificial intelligence (AI) is seen as a solution to bridge this gap in adenoma detection, which is a quality indicator in colonoscopy. AI systems utilize deep neural networks to enable computer-aided detection (CADe) and computer-aided classification (CADx). CADe is concerned with the detection of polyps during colonoscopy, which in turn is postulated to help decrease the adenoma miss-rate. In contrast, CADx deals with the interpretation of polyp appearance during colonoscopy to determine the predicted histology. Prediction of polyp histology is crucial in helping Clinicians decide on a "resect and discard" or "diagnose and leave strategy". It is also useful for the Clinician to be aware of the predicted histology of a colorectal polyp in determining the appropriate method of resection in terms of safety and efficacy. While CADe has been studied extensively in randomized controlled trials, there is a lack of prospective data validating the use of CADx in a clinical setting to predict polyp histology. The investigators plan to conduct a prospective, multi-centre clinical trial to validate the accuracy of CADx support for prediction of polyp histology in real-time colonoscopy.
