Filter by: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.
Patients undergoing an operation for colorectal cancer are normally treated with non-steroid-anti-inflammatory-drugs (NSAIDs) e.g. ibuprofen as pain medication after the operation. It is well known that NSAIDs can be harmful to kidney-and heart patients and some studies also have shown an increased risc of surgical complications after treatment with NSAIDs. On the other hand recent studies have found a preventive effect of NSAIDs on colorectal cancer recurrence thus leaving the colorectal surgeon in doubt whether NSAIDs are beneficial or harmful to colorectal cancer patients. In the department of colorectal cancer surgery at Zealand University Hospital it was decided to leave out NSAIDs from the 1st of april 2016. This study will investigate if there is a change in consumption of opioids before and after omission of NSAIDs. This will be an important finding because opioids also have harmful side-effects as well as a risk of addiction. The investigators will also compare the blood samples and see if there is signs of impaired renal and cardiac function in the group that was treated with NSAIDs. Finally the long term outcomes will be investigated such as cancer recurrence and death in the two groups.
The focus of the study is to evaluate impact on Adenomas Per Colonoscopy (APC) with a Computer Aided Detection (CAD) software assisting the gastroenterologist during a colonoscopy procedure.
Briefly, this is a 28-day dietary intervention study participants will be asked to eat 2 ounces (52 grams) of walnuts every day for 3 weeks, and at the end of the study period they will come in for a colonoscopy. Participants will first start a 1-week run-in period where they will be asked to avoid foods high in ellagic acid. In addition, they will be asked to complete food surveys and two sets of 3-day dietary records, and to provide colon biopsies for this study during their routine colonoscopy, as well as a blood, and two urine and stool samples. Urine samples will be used for analysis of urolithin, ellagic acid metabolites. Stool samples will be used to assess gut microbiota changes after walnut consumption. Dietary records will be used for compliance and Food Frequency Questionnaire will be used to assess dietary habits. Lastly, the biopsy samples will be used for analysis of biomarkers and anti-inflammatory in the colon, as well as adherent microbiome to the colonic tissue. Data will be analyzed based on the urolithin phenotypes.
The objective of this Clinical Sample Collection Study is to develop a biobank of appropriately collected plasma samples from colorectal cancer patients (i.e. AJCC/UICC stages 0, I, II, III) prior to therapeutic intervention, and from people reporting for colorectal cancer screening by colonoscopy, prior to bowel preparation.
To evaluate the performance of Check-Cap Imaging System in healthy volunteers in a variety of operating scenarios. The Back recorder unit is the primary module for evaluation The participants DO NOT ingest a capsule and the capsules do not have any radioactive source
Local percutaneous thermal ablation is frequently proposed in the management of metastatic diseases. Radiofrequency ablation (RFA) has demonstrated good results when the metastatic disease is limited and slowly evolving. The destruction of solid metastasis by RF leads to inflammatory and immunological mechanisms that remain poorly understood. These pathological events may influence the overall and anti-tumor host immune responses. The purpose of the study is to identify and quantify some immune mechanisms triggered by RFA of pulmonary metastases from colorectal cancer origin.
The purpose of this study is to examine the role of an automatic polyp detection software (henceforth referred to as the research software) as a support system during colonoscopy; a procedure during which a physician uses a colonoscope or scope, to look inside a patient's rectum and colon. The scope is a flexible tube with a camera-to see the lining of the colon. The research software is used to aid in the detection of polyps (abnormal tissue growths in the wall of the colon and adenomas (pre-cancerous growths) during colonoscopy. The research software used in this study was programmed by a company in Shanghai, which develops artificial intelligence software for computer aided diagnostics. The research software was developed using a large repository (database or databases) of polyp images where expert colonoscopists outlined polyps and suspicious lesions. The software was subsequently developed and validated using several databases of images and video to operate in near real-time or within minutes of photographing the tissue. It is intended to point out polyps and suspicious lesions on a separate screen that stands behind the primary monitor during colonoscopy. It is not expected to change the colonoscopy procedure in any way, and the physician will make the final determination on whether or not to biopsy or remove any lesion in the colon wall. The research software will not record any video data during the colonoscopy procedure. In the future, this software may help gastroenterologists detect precancerous areas and decrease the incidence of colon cancer in the United States.
The Efficacy and safety of Non-anesthesiologist administered propofol (NAAP) for gastrointestinal endoscopy have been widely documented although there is not information which has evaluated the outcomes of colonoscopy it self when the endoscopist has to fulfill the additional task of supervising the sedation. Objective: To determine the equivalence of adenoma detection rate (ADR) in colorectal cancer (CRC) screening colonoscopies performed with NAAP and performed with monitored anesthesia care (MAC). Method: Single blind non-randomized controlled equivalence trial. Patients: Adults between 50 - 69 years old from National CRC screening program (CRCSP). Intervention: The patients are blindly assigned to undergo either colonoscopy with NAAP or MAC according to the arrival of fecal occult blood test, patient's suitability for colonoscopy date and availability of places at endoscopy schedule (with NAAP or MAC).
Background: Participants in the colon and rectal cancer (CRC) screening program that have a positive result in the Fecal Immunological Test (FIT) are visited by the screening nurse who explains the meaning of the positive test and the need to perform a colonoscopy. Having a positive result in the screening test can have a negative psychological impact on patients causing anguish. Objective: To evaluate whether the use of iconographies to communicate the risks of possible diagnoses to patients with positive FIT improves the understanding of the information and reduces the degree of anguish. Methods: Quasi-experimental pre-post intervention study with a control group. 240 individuals (men and women between 50-69 years of age, with a positive FIT result attending the nursing visit) will be included in two non-concurrent study groups (120 individuals per group). The control group will receive the nurse visit as usual. For the intervention group, the nurse will use iconographies to communicate the risk of the different possible diagnoses and the risk of complications of the colonoscopy. The degree of distress (Distress Thermometer and a scale of emotion-faces) will be measured before and after the visit and the understanding of the information (visual analog scale) after the visit. The degree of distress between the control group and intervention group will be compared. If the results are favorable, the systematic use of iconographies can be implemented in the nursing screening visit and be extended to other Screening Units.
