Active clinical trials for "Colorectal Neoplasms"

Anastomotic leakage (AL) is one of the major complications after gastrointestinal surgery. Compromised tissue perfusion at the anastomosis site increases the risk of AL. Indocyanine green (ICG) combined with fluorescent near infrared imaging has proven to be a feasible and reproducible application for real-time intraoperative quantification of the tissue perfusion and cohort studies showed reduced leakage rate. Unfortunately, these studies were not randomized. Therefore, we propose a nationwide randomized controlled trial to identify the value of ICG for AL in colorectal anastomosis.

A total of 138 consecutive patients who underwent laparoscopic-assisted or open colectomy for colorectal cancer (CRC) were included in the present study. Subjects commonly shared a condition of overweight or obesity. The investigators aimed to define any difference between the two different groups (open vs laparoscopic-assisted surgery) and a series of outcomes, i.e. hospitalization, Lymph nodes number, Intra-Surgery complications, and Clavien Dindo score.

The aim of this study was to compare the willingness to use and attitude towards VC amongst both patients with colorectal cancer and healthcare providers during follow up care. Second, to determine the satisfaction with the quality of the healthcare provider and the usability of the used VC technology. 50 patients will be asked to choose between video consultation or face-to-face contact at the outpatient surgical clinic.

Patients aged ≥75 year scheduled for CRC surgery were studied (104 cases) and variables associated with major postoperative complications / mortality were evaluated. The importance of this report is that MPI-score resulted strongly associated with major complications and it was a primary component of an individual prediction model.

Early onset colorectal cancer (cancer in person younger than 50 years) has increasing incidence last years. The aim of our study was to assess the real-life incidence of early onset colorectal cancer, advanced neoplasias (colorectal cancer and/or advanced adenoma) and all neoplastic lesions in total in a single non-university endoscopic center.

The search for biochemical markers in patient's blood for non-invasive colorectal cancer diagnostic has not yielded satisfactory results to date. The search for blood in the stool by enzymatic techniques has certainly allowed the diminution of colorectal cancer mortality but its low sensitivity is still a disadvantage. The new immunological tests for search blood test in the stool are more sensitive and more specific but still insufficient. The originality of this project is based on the use of new technology developed in fundamental research based on the detection of circulating exosomes from tumor cells in the patient's serum. The detection of protein markers transported by tumor exosomes is original and innovative approach because it's still not considered in the literature. The use of innovative and non-invasive health technologies for the patient is an important factor in the care of patients in their health care journey. The non-invasive nature of the project could reduce the reticence of patients to participate in cancer screening. The results expected from the study can have a direct impact on the management of patients suspected of having colon cancer and thus make it possible to optimize the earliness of their diagnosis.

The primary objective of this sub-study is to obtain de-identified, clinically characterized, stool specimens from subjects with untreated solid tumors for research use in the development and validation of a stool-based test for colorectal cancer.

This is an observational study in which data from patients with metastatic colorectal cancer in three European countries who received STIVARGA® (regorafenib), are collected. In observational studies, only observations are made without specified advice or interventions. Metastatic colorectal cancer (mCRC) is a cancer that starts in the large bowel or the rectum (the lowest part of the gut) and has spread to other parts of the body. Regorafenib is an anti-cancer drug that blocks several proteins called enzymes, which are involved in the development and growth of cancer. A wide range of such enzymes called tyrosine kinases are targeted. In 2013, regorafenib was approved in Europe for doctors to prescribe to people with mCRC who have previously been treated or cannot receive other available treatments. It is known that doctors may change/reduce the amount (the dose) of regorafenib they give (flexible dosing), so that the patients better tolerate the treatment. However, little information is available on the doses of regorafenib given in France, Italy, and Belgium in usual practice. In this study researchers want to learn more about how and in which amount regorafenib is usually given to patients with mCRC in France, Italy, and Belgium: at the beginning during, and at the end of the regorafenib therapy. In addition, the study team will collect data about/if: the treatment duration at each treatment dose of regorafenib, the number of people who received reduced initial dosing of regorafenib in real word settings in France, Italy, and Belgium, reduced (flexible) initial dosing of regorafenib allows patients to stay longer on treatment. To answer these questions, the researchers will look back at cases that have already happened when the study begins. The data will be collected through an online case report form. The doctors will provide case histories of mCRC patients who started regorafenib treatment in most recent 3 years and 4 months (from January 1, 2019 to Apr 30, 2022) or up until 3 months prior to the date of data collection. Besides this data collection, no further tests or examinations are planned in this study. There are no required visits or tests in this study.

France is among the countries with a high incidence of colorectal cancer. The prognosis associated with colorectal cancer is related to the development stage of the disease at diagnosis. Thus, when the cancer is detected and treated at an early stage, the survival rate at 5 years was 90%. It is therefore a major issue of screening is widespread in France since the end of 2008. This screening is based on a two step strategy: 1) the occult blood in the stool (FOBT) and if positive 2) the realization of an optical colonoscopy examination currently regarded as the evaluation procedure colon reference. But as part of this organized screening, 13% of those with a positive FOBT ultimately refuse to have an optical colonoscopy. Under the refusal, virtual colonoscopy may be proposed as an alternative according to the recommendations of the National Health Authority in 2010. But it has never been assessed as part of organized screening. Similarly another alternative is recently developed colic capsule that benefits of development in recent years of the capsule for the small intestine which has become the gold standard for diagnosis of most diseases of the small intestine (bleeding occult, diagnosis of unknown colitis...). Therefore the study proposes virtual colonoscopy or colon capsule for people with a positive FOBT as part of organized screening and did not realize optical colonoscopy after the usual procedure and complete recovery. This study aims to answer the question of the place of colic capsule as part of organized screening. An economic component is integrated to assess, in terms of health insurance, the cost associated with these two exams, and compare them to the cost of optical colonoscopy. The proposed study is an observational study of impact of an alternative screening strategy for colorectal cancer whose primary objective is to compare the rate of acceptance of virtual colonoscopy and colon capsule in patients refusing optical colonoscopy.
