Active clinical trials for "Colorectal Neoplasms"

Background. The Nosocomial Infection Surveillance Program in Catalonia (VINCat) monitors SSI in elective colorectal surgery since 2007 in 56 hospitals (7.5 million population). These hospitals perform active and prospective standardized surveillance of elective colorectal resections. Post-discharge surveillance is mandatory up to 30 days after surgery. Between 2007 and 2015, the SSI rate did not change significantly, with a cumulated incidence of 5,491 SSI in a total of 29,006 interventions (19%). In 2015, a working group of VINCat specialists and surgeons from the Catalan Society of Surgery was set up to formulate a specific bundle of SSI preventative measures for colorectal surgery. Aim. To analyse the effect of a specific bundle for SSI prevention in elective colorectal surgery. Methods. In 2016, a bundle of six preventative measures was recommended to the VINCat hospitals. Bundle measures were: systemic and oral antibiotic prophylaxis, mechanical bowel preparation (MBP), laparoscopic surgery, maintenance of normothermia, and the use of a double-ring wound retractor. The results of SSI before and after the implementation of the bundle are compared. The results are analysed using the chi-square test (statistical significance p <0.05).

This pilot trial evaluates the feasibility of a group diet education program for stage I-IV colorectal cancer survivors. Providing a nutrition education program for colon and rectal cancer survivors may help them have better access to the tools necessary to make healthy food decisions that can impact their cancer outcomes.

The purpose of the study is to examine the efficacy of educational materials to promote hepatitis C virus (HCV) screening and colorectal cancer (CRC) screening uptake among adults born between 1945-1965.

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.

Blood that can be detected in stool via faecal immunochemical testing is a recognised risk factor for the presence of colorectal cancer. There are a number of point of care faecal immunochemical testing devices available. This study is to trial one of these machines into the clinical setting to see if the results are safe and accurate as a 'rule out' test for colorectal cancer. We will be investigating patients that present with symptoms or anaemia to their GP and are referred on the two-week rule pathway to our hospital. It has also been advocated that digital rectal examination (which is part of the routine assessment for a patient presenting to colorectal clinic) provides an opportunity to use a small sample of stool from a gloved finger to perform faecal immunochemical testing. We will be comparing a patient provided sample with a DRE sample on a standard laboratory-based machine.

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.

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.

Anastomotic leakage is serious morbidity that can develop in patients operated on for colorectal cancer and can reach potentially life-threatening dimensions. Many international studies have been conducted to reduce and eliminate this postoperative complication that may have a mortal course. In these studies, preoperative, perioperative and postoperative factors of the patient, operation techniques, structure of the material used in the operation and multiple factors belonging to the surgeon were held responsible. Intraabdominal sepsis secondary to late anastomotic leakage and subsequent multiorgan failure can cost the patient's life. Anastomotic leaks that develop in patients who have been operated for colorectal cancer; In order to detect patients' postoperative clinical findings, laboratory examinations, imaging tests, and to eliminate them before intraabdominal sepsis develops, studies including many different laboratory and imaging methods have been carried out. Although previous studies have shown that there are many laboratory examinations and imaging methods that can predict anastomotic leaks early, they have many advantages over each other in terms of efficiency, sensitivity, specificity, and cost. The investigators aimed to investigate the effectiveness of C reactive protein and blood sodium value, as well as their superiority, among the tests that can predict postoperative anastomotic leakage, especially in patients who have undergone a single anastomosis following resection for non-metastatic colorectal cancer.

Using social media for health promotion is an innovative and emerging approach but remains relatively unexplored in cancer screening. Uptake of colorectal cancer (CRC) screening remains low and standard methods of reaching out are expensive with limited impact. The objective of this study is to conduct a cluster randomized controlled trial (RCT) to test the effectiveness of social media messages for CRC screening on screening intention (primary outcome). The results of this trial will be of interest to Cancer Care Ontario and are likely to be taken up by other screening programs looking for innovative and novel ways to increase screening participation. The study results will be easily translatable identifying the most compelling CRC screening messages while the approach can easily be translated to other cancer disease sites with screening programs.

This retrospective study, will evaluate patient outcomes after triplet chemotherapy (FOLFIRINOX) (5 Fluorouracil + oxaliplatin + irinotecan) plus cetuximab 1st line treatment focusing on efficacy and safety in a RAS (KRAS, NRAS (neuroblastoma rat sarcoma viral oncogene homolog) wild-type metastatic colorectal cancer population, and according to BRAF (murine sarcoma viral oncogene homolog B) status and primary tumor location.
