Active clinical trials for "Colorectal Neoplasms"

This observational follow-up study of the randomized trial (RCT) DIQOL investigates long-term effects of an intervention with quality of life (QoL) diagnosis and therapy on present QoL, survival, and recurrence-free survival of colorectal cancer survivors more than 5 years after surgery. Moreover, patients' experiences with aftercare for colorectal cancer during the COVID-19 pandemic and their recollections of their illness and therapy are examined.

To conduct a randomised control trial to test the effectiveness of telephone outreach programme to improve the uptake rate of repeat fecal occult blood test in colorectal cancer screening programme.

Acetylsalicylic acid (ASA) seems the ideal colorectal cancer (CRC) chemoprevention agent. Several ongoing trials are testing the effect of ASA as co-therapy in CRC. The mechanisms of action, the appropriate dose and the ideal target population are unknown. The investigators have demonstrated that doses of 100 mg of ASA induce direct and partial but persistent acetylation of the cyclooxygenase (COX) isoenzyme COX-1 in the normal colorectal mucosa. The primary objective is to perform a study of aspirin by using a proteomic assay for comparing platelet COX-1 and CRC mucosal COX-1 after different doses of ASA. Secondary objectives are: the measurement of prostaglandin E2 (PGE2) and phosphorylated S6 protein (p-S6) levels in CRC mucosa, the assessment of indirect biomarker of aspirin action (serum thromboxane B2 (TXB2) and urinary levels of 11-dehydro-TXB2 (TX-M)), the evaluation of systemic biomarkers of inflammatory/tumorigenic COX-2 by assessing urinary levels of major metabolite of PGE2 (PGE-M). Methods: Phase II randomized clinical trial in 60 patients with newly diagnosed CRC in 3 groups of 20 patients receiving 100 or 300 mg/day, or 100 mg/12 hours of enteric-coated ASA for 3±1 weeks, prior to definitive treatment by surgery. Main outcome: Acetylation of COX-1 and COX-2. Eicosanoid levels in target organs. Expected results: Evidence for the current uncertainty about the mechanisms of action and the dose required to obtain the best chemopreventive effect with ASA in CRC. Confirm acetylation of COX as a key biomarker of efficacy with ASA.

Introduction: Successful colorectal surgery is determined based on postoperative mortality and morbidity rates, complication rates, and cost-effectiveness. One of the methods to obtain an excellent postoperative outcome is the Enhanced Recovery After Surgery (ERAS) protocol. This study aims to see the effects of implementing an ERAS protocol in colorectal surgery patients. Methods: Eighty-four patients who underwent elective colorectal surgery at National Tertiary-level Hospital were included between January 2021 and July 2022. Patients were then placed into ERAS and control groups according to the criteria. The Patients in the ERAS group underwent a customized 18-component ERAS protocol and were assessed for adherence. Postoperatively, both groups were monitored for up to 30 days and assessed for complications and readmission. The investigators then analyzed the length of stay and total patient costs in both groups.

Colorectal cancer is one of the most common causes of cancer-related death. Early diagnosis is extremely important in terms of treatment and mortality. In this study, we investigated the diagnostic value of serum autotaxin levels in colorectal cancer.

Colorectal carcinoma is a major health problem. As a malignant tumor, the malignant potential of colorectal carcinoma is based mainly on its ability to metastasis to different sites. Fascin-1 is an actin binding protein which is involved in reconstruction of intracellular actin network, the latter enforces the neoplastic cell to invade surrounding structures.

Study is designed to investigate the risk factors associated with morbidity and mortality in patients who underwent emergency resection because of colorectal cancer in general surgery clinic of a tertiary referral hospital.

The purpose of this study is to estimate the overall survival (OS) for US participants diagnosed with metastatic colorectal cancer (mCRC) by using Flatiron Health's individual patient level data.

Rationale: Since January 2014 the Dutch screening programme for bowel cancer has been implemented. Screening will increase the demand for surveillance. Although patients in whom adenomas have been removed are at increased risk of progressing to cancer, solid evidence on the reduction of death from CRC through the current colonoscopy-based surveillance is lacking. Furthermore, colonoscopy-based surveillance leads to high logistic demands, high individual burden and high costs. Therefore, there is need for new surveillance strategies. Stool-based molecular testing (Cologuard®, consisting of a stool DNA test and an immunochemical assay for human hemoglobin) or Faecal Immunochemical Testing (FIT) may serve as an alternative for colonoscopy surveillance. The aim of this study is to compare the accuracy of an established molecular stool test (Cologuard®) and FIT to colonoscopy for detection of advanced adenomas or CRC (advanced neoplasia) in a surveillance population. These outcomes will be used to model various strategies of stool-based molecular surveillance to inform health policy decisions.

Objective : to demonstrate that providing to GPs a list of their patients who are not compliant to colorectal cancer screening will 1) enhance patient participation to screening, and 2) decrease the proportion of cancer diagnosed outside the screening organisation. Design : Randomised controlled study, 3 parallel arms. Enrollment: GPs allocated in the 3 groups of the study will be all GPs 1) from the "Loire-Atlantique and Vendée" geographic area (1300 GPs on average) and 2) who have more than 100 patients in their patient list (based on data provided by the Healthcare Insurance System Services). Patients will be eligible to the study depending on their eligibility to the Faecal Occult Blood Test for colorectal cancer screening : 1) they should be older than 50 and younger than 74; 2) they should not have a personal history of colorectal cancer (or history of adenoma bigger than 1 cm) nor a family history of colorectal cancer. Main outcomes measures : Patient participation to colorectal cancer screening, and number of cancers screened in (versus diagnosed outside) the screening procedure.
