This project has for objective to demonstrate that the increase of the distance "Patient home - center of treatment" may be associated with significant, other noticeable, noted events. This distance may also be available in the Rouen University Hospital. The study of the association in this distance and the delay in initiating chemotherapy after surgery in patients treated at the CHU correspond to a pilot study prior to the completion of the analysis at the regional scale.
Freenome is using a type of artificial intelligence, called machine learning, to identify patterns of cell-free biomarkers in blood to detect cancer early. The purpose of this study is to develop and validate a blood-based assay to detect colorectal cancer by collecting blood and stool samples from healthy patients undergoing routine screening colonoscopy and from patients recently diagnosed with colorectal cancer or advanced adenomas.
A mixed methods randomized control trial assessing the impact of early palliative care incorporation in liver cancer and metastatic colorectal cancer on caregiver well-being, patient physical and psychosocial outcomes, and health services utilization.
In colorectal surgery, hand suturing and stapling are routine methods for performing intestinal anastomoses, and these methods appear to be similar in terms of clinical safety. Despite several years of experience with surgical procedures as well as improvements to the medical devices, problems with disturbed anastomotic healing leading to leakage and stenosis after colorectal surgery remain a significant challenge for surgeons. In addition, preoperative radiotherapy has been shown to increase the risk of anastomotic leakage even further. The methods that are used today to detect leakages are unfortunately inaccurately and limited to monitoring symptoms, temperature, CRP (C-reactive protein)-levels, and performing abdominal examinations and CT-scans. These clinical signs and parameters usually become apparent several days after onset of the leakage, which leads to a delayed diagnosis. Anastomotic leakage is not only a significant cause of increased morbidity of complications and mortality in patients, but also associated with increased risk of local recurrence and poor prognosis. Moreover, when reoperation is required to fix the leakage, a permanent stoma may be made at the level of the sigmoid colon and this procedure impacts quality of life negatively. Based on the above considerations, a novel, adaptive anastomotic method has been developed by CarpoNovum to achieve a safer anastomosis. The method's working name is C-REX Ring-locking Procedure (C-REX is referred to our Colorectal anastomotic rings for Re-join the intestinal ends and validate the anastomosis, with function of Extract samples for analysis and conduct X-ray through connected catheters). The novel adaptive anastomotic medical devices, C-REX LapAid and C-REX DMH/DMHC are easy to use, with unique possibility to control the anastomosis during and after surgery. The previous successful preclinical study encourages a clinical verification in patients undergoing colonic resection to evaluate the safety and performance of C-REX Ring-locking Procedure by use of C-REX LapAid and C-REX DMH/DMHC.
Colorectal cancers (CRC) are the third most common human malignancy, and are also the leading cause of cancer related deaths worldwide. Early detection of premalignant lesions such as adenomatous polyps has decreased the risk of CRCs; however, cases which are initially undetected and progress to advanced CRC with distant metastasis are still unfortunately incurable. The development of CRC is a complex and heterogeneous process arising from an interaction between multiple etiological factors, including genetic factors and environmental factors such as diet and lifestyle. The challenges are to understand the molecular basis of individual susceptibility to colorectal cancer and to determine factors that initiate the development of the tumor, drive its progression, and determine its responsiveness or resistance to antitumor agents. Next generation sequencing(NGS)-driven genomic studies are already reporting novel features of cancer genomes beyond the traditional mutational categories. Recent advance in sequencing technology has enabled comprehensive profiling of genetic alterations in CRC.These methods are facilitating an increase in the efficiency and resolution of detection of each of the principal types of somatic cancer genome alterations, including nucleotide substitutions, small insertions and deletions, copy number alterations, chromosomal rearrangements,DNA methylation sequencing such as bisulfite-sequencing and microbial infections. Besides the microsatellite instability (MSI), some researchers reported novel mitochondrial mutations in the cancer genomes. NGS technology will help the investigators for understanding of entire CRC genomes and the obtained knowledge will lead to a better diagnosis and personalized targeted therapeutics for CRC management
The conventional total dose of 4 L of polyethylene glycol (PEG) given the day before the procedure is safe and effective. It has been the standard cleansing regimen for the last 25 years. To overcome the difficulty in completing the bowel preparation due to large volume and/or taste, reduced-volume (mixed) bowel preparation of bisacodyl and 2 L of PEG have been shown to provide adequate colon cleansing and better tolerability. LoVol-esse is a reduced-volume PEG-based bowel preparation to be used in combination with bisacodyl and designed to improve patient tolerability and attitude toward bowel cleansing prior to colonoscopy thanks to the reduced volume and improved taste. The present study is intended to compare the new dosing regimen of the bowel lavage solution given the same day compared with standard PEG formulation (SELG 1000) given the day before colonoscopy.
