Filter by:The aim of this study is to determine accuracy and predictive values for colorectal cancer of a faecal quantitative immunochemical test (FIT) in unselected symptomatic patients presenting in primary care. Main reference test will be linkage to a nationwide colorectal cancer registry.
This was a single-arm, prospective study to investigate the safety of cetuximab in combination with trifluridin tipiracil (TAS-102) in the third-line treatment of Chinese patients with RAS wild-type mCRC.
Adenoma detection rate (ADR) has been the most important quality indicator on colonoscopy because ADR was reversely related with CRC incidence and mortality. Several image enhanced technologies, such as narrow-band imaging (NBI) or linked colour imaging (LCI) had been proved to have ability to increase the ADR. 3D techonology, however, has not been validated on colonoscopy performance. Therefore, current study was to compare the ADR between new 3D colonoscopy and conventional 2D colonoscopy.
There is no consensus about the best bowel preparation prior to transanal endoscopic surgery TES). Cleanliness and visibility in the rectosigmoid and rectum are of utmost importance, possibly even more so than during colonoscopy, to facilitate safe, precise and efficient resection of the rectal lesion and potentially adequate closure of the defect. Both Fleet enemas and oral mechanical bowel preparation are considered standard of care in preparation for TES. This single center two arm single blinded randomized controlled trial will compare the effectiveness of Fleet enemas in comparison to Pico Salax oral mechanical bowel preparation in cleansing the rectum as measured by a modified version of the Ottawa Bowel Prep Scale.
The LIVACOR - Trial is a European wide, randomized controlled, open-label, multicenter trial. Patients with synchronous colorectal liver metastases (CRLMs) and primary colorectal tumor are considered eligible and will be randomized between minimally invasive (MI) combined or staged colorectal resection (all colectomies, including high anterior resection) and liver resection of up to three segments.
This proposed study is designed to investigate the specific uptake of fructose by human colorectal tumors. In this study, subjects with colorectal cancer undergoing surgery will receive an oral sugar solution containing fructose or xylose prior to surgery. The tumor will then be resected, and a portion of the tissue will be used to measure the abundance of fructose and xylose. The study hypothesis is that the tumors will take up fructose sugar but not xylose sugar. A comparison of the sugar uptake between the tumor and normal tissues from the adjacent intestinal epithelium and smooth muscle and the liver will be conducted. This proposal will confirm that human colorectal cancer tumors can directly absorb dietary sugars, which has never been demonstrated.
230 patients with colorectal cancer liver metastases will be randomly assigned to resection or thermal ablation.
Colorectal cancer (CRC) is the second leading cause of cancer-related death in the Western world. Overall survival (OS) remains poor, with 50% estimated 5-year survival. In Italy, current estimates indicate that in 2020 a number of 43.700 patients have been affected by colorectal cancer, with an increasing of diagnosed cases in both men and women. It is clear that it is worthwhile to investigate the evaluation of colorectal cancer which could reflect a different spread of screening programs or be the effect of different timing in the start of the programs themselves. To improve the overall survival of colorectal cancer patients, robust biomarkers for screening and predicting disease recurrence could help identify high-risk patients, facilitate a close patient follow-up, and decide appropriate treatment regimens during the postoperative care. Colonoscopy remains the most efficient method for detecting CRC, yet its general application in the setting of screening is limited due to the uncomfortable experience and the high costs. accumulating studies have revealed the potential of systemic inflammatory markers such as C-reactive protein (CRP), albumin, neutrophils, platelets, and lymphocytes, and also biomarker combination ratios [(eg, CRP-albumin ratio (CAR), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR)] as prognostic biomarkers in different cancers, including CRC. Chronic inflammation affects all stages of tumor development. Several studies have shown that various preoperative markers reflecting systemic inflammatory response, including NLR and CRP ratio, offer predictive potential for postoperative morbidity and mortality in CRC patients. However, several issues require addressing prior to the adoption of these inflammatory markers in the clinical practice for CRC patients undergoing surgery: a) the combination of inflammatory factors that might be best in predicting oncological outcomes in colorectal cancer patients remains unclear; b) previous studies for systemic inflammatory markers have mainly interrogated their prognostic potential for oncological outcomes but have not laid emphasis for evaluating their predictive value for postoperative complications; c) there is a lack of consensus on the cut-off thresholds used for each marker for determining mortality risk resulting from surgical and oncological outcomes.
The purpose of the study is to determine if the type of catheter used in the mapping procedure prior to radioembolization improves the delivery of radioactivity to tumor(s) in participants with liver cancer. The name of the devices involved in this study are: - Pressure Enabled Drug Delivery (PEDD)/TriNav Infusion System - Standard 2.4F microcatheter, not otherwise specified
The purpose of this study is to collect clinical specimens from subjects with a diagnosis of colorectal cancer/advanced adenoma or undergoing a screening colonoscopy and meeting study eligibility criteria.
