Filter by:The complication rate in colorectal surgery is high and shows a large variance depending on the patient and the treating surgeon. The primary aim of the presented study is to evaluate the introduction of a colorectal bundle to reduce the complication rate in left sided colorectal resections. The colorectal bundle is a catalog of measures consisting of several items These are for example preoperative risk stratification, antibiotic and mechanical bowel preparation and preoperative showering. The primary endpoint will be the complication rate measured as the comprehensive clinical index (CCI) within 30 days. Investigators will include patients that undergo elective or emergency left sided colorectal surgery.
This is a prospective, multi-endoscopist, single center, clinical study at tertiary referral center that addresses an important current challenge in the prevention of colorectal cancer (CRC), namely, how to improve the complete removal of CRC precursors. This study will observe the potential benefit of specific polypectomy technique in conjunction with a systematic submucosal injection prior to the polyp resection. This study will evaluate the completeness and incompleteness of the resection of colorectal neoplastic polyps during the procedures.
Colorectal cancers are the third most common type of cancer in the world. Peritoneal carcinomatosis and intraabdominal acid development occur in advanced stages of colorectal cancers. It is known that the immune system plays an important role in tumor development or tumor eradication. Among the mechanisms of escape from the immune system, changes in the tumor microenvironment play an important role. Immune checkpoints are molecules that have become popular especially after the Nobel Prize in 2018, and are important in revealing the relationship between cancer and the immune system. In our study, it is aimed to evaluate whether there is a difference in intraabdominal ascites fluid immune checkpoints level in patients with advanced colorectal cancer patients compared to patients without malignancy.
Colorectal cancers are the third most common type of cancer in the world. Peritoneal carcinomatosis and intraabdominal acid development occur in advanced stages of colorectal cancers. It is known that the immune system plays an important role in tumor development or tumor eradication. Differentiation of T cells towards Th2 and regulatory T cells is also reported to be effective in tumor progression. Among the mechanisms of escape from the immune system, changes in the tumor microenvironment play an important role. The role of regulatory T lymphocytes, a subgroup of T cells that play a regulatory role by suppressing the function of other T lymphocytes, is to reduce the chronic immune response against viruses, tumors and patients's own antigens. The common feature of all Tregs is that they secrete one or more anti-inflammatory molecules such as IL-10, TGFβ or IL-35. High levels of Tregs have been found in peripheral blood, tumor tissue and lymph nodes in patients with malignancy. In our study, it is aimed to evaluate whether there is a difference in intraabdominal ascites fluid T helper cytokine levels in patients with end-stage colorectal cancers compared to patients without malignancy.
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.
An observational study of the relationship between fat free mass and toxicity of cytostatics in cancer patients, at the department of Clinical Oncology at Zealand University Hospital, Roskilde, Denmark. Fat free mass will be measured by bio impedance spectroscopy and data on toxicity will be obtained from medical records and interviews/questionnaires with the patients.
The study is testing an intervention of an investigator-developed chemotherapy dose adjustment algorithm. The primary objective of this study is to evaluate the effectiveness of the chemotherapy dose adjustment algorithm for reducing unplanned delays in patients receiving FOLFOX (5-fluorouracil, leucovorin, and oxaliplatin)-type chemotherapy, while maintaining acceptable chemotherapy dose-intensity.
To investigate whether the dose predicted by pre-therapy 99mTc MAA SPECT predicts the dose to the liver from the 90Y microspheres as assessed by post-therapy 90Y SPECT/CT or positron emission tomography (PET)/CT.
Investigating people with bowel symptoms uses a test that detects traces of blood in the stools, the FIT test. There are many possible reasons for positive tests. A few people have cancer. However, most participants with symptoms don't have any serious bowel disease but have benign problems such as piles or irritable bowel syndrome (IBS). It is very difficult to diagnose on symptoms alone, those participants who have serious bowel disease and those who do not. After a positive test, people are invited for colonoscopy - a sort of articulated tube that is passed up the bowel. Most people invited for colonoscopy don't have cancer. Only about 5% of those with positive FIT tests have cancer. About 25% have other bowel diseases, but most have nothing serious wrong at all. So they have the inconvenience and discomfort of colonoscopy but don't get any benefit from it. The investigators want to try adding another test, the volatile organic compound (VOC) test, to see if the investigators can separate those with positive FIT tests who do have something wrong, from those who don't. The VOC test uses a urine sample. Using both tests might also be better for detecting cancer. FIT alone misses about 20%. So the investigators think that using both tests might not only be better for detecting cancer, but also might mean that a lot of people will avoid having to have colonoscopy. This study will recruit 1,819 participants with bowel symptoms from NHS trusts in the UK. They will provide stool samples for FIT and urine for VOC analysis. They will have colonoscopy to get a definite diagnosis. Then the investigators will look at their FIT and VOC test results to see if in future, people with both tests negative.
The purpose of this study is to assess whether computer aided technology (CAD) can help in the diagnosis of polyps found the bowel compared with visual inspection alone and therefore whether it is beneficial in helping clinicians to decide whether to remove a polyp or not. Presently, most endoscopists remove all polyps found and send them to the laboratory for testing. The number of colonoscopies is increasing, meaning that more polyps are detected and removed. This comes at a significant cost to the health service and increases the time taken to complete a colonoscopy.
