Filter by:Patients without alarming symptoms are at low risk of bowel cancer . However, in majority of those patients colonoscopy (gold standard) is needed to diagnose colorectal cancer or other non-neoplastic conditions such as Inflammatory bowel disease . Evaluation of patients with lower gastrointestinal symptoms ( low-intermediate risk group) represent significant pressure for colonoscopy services . At the end of August 2019 there were a total 44,388 patients still waiting for colonoscopy. Covid 19 pandemic has placed significant pressure on healthcare systems since March 2020.The aerosol generating potential of endoscopy has led to multiple Gastroenterology and Endoscopy societies suggesting immediate cessation of all but emergency colonoscopy during the peak phase of the pandemic which put colonoscopy capacity even more under pressure Data from the National Endoscopy Database indicate that total endoscopic activity fell rapidly to 5% of normal levels during the peak phase of the COVID-19 epidemic in the UK (from approximately 35 000 reported procedures per week to 1700, for the week ending 13 April . In order to reduce potential diagnostic delays as a result of COVID pandemic , the role of colon capsule endoscopy (CCE) as a non invasive diagnostic test is being increasingly recognise, which allows for a pain-free colonic assessment by eliminating the need for instrument insertion, gas insufflation or sedation . The aim of the 5G SUCCEEDS study is to trial feasibility of home delivery of Colon Capsule Endoscopy service with the help of 5 G technology. Currently patients need to attend hospital to access this service.
This study will evaluate the safety, and tolerability of Cadonilimab as neoadjuvant treatment for resectable local advanced colorectal cancer patient with dMMR/MSI-H.
The goal of this observational study is to explore the safety and feasibility of laparoscopic intracorporeal anastomosis in colorectal cancer surgery. The main questions it aims to answer are: 1. If intracorporeal anastomosis is safe in terms of short-term outcome? 2. If intracorporeal anastomosis can achieve the same oncological outcome as conventional extracorporeal anastomosis?
The purpose of this study is to characterize the safety, tolerability, PK, and efficacy of INCB 99280 in combination with ipilimumab in participants with select solid tumors.
Immune checkpoint inhibitor (ICI) treatment has produced striking results in patients with colorectal cancer (CRC) of the subtype deficient mismatch repair (dMMR). The majority of patients, however, have proficient MMR (pMMR) tumors, with limited effect of ICIs. The key difference between dMMR and pMMR tumors is the infiltration of cytotoxic T-cells. dMMR tumors have increased infiltration and thus increased efficacy from ICI treatment. The investigators conducted a proof of concept study where the investigators applied an intratumoral (IT) unaltered flu vaccine in ten patients with non-metastatic pMMR CRC. The intervention increased infiltration of cytotoxic T-cells and the immune checkpoint PD-L1, suggesting that IT flu vaccine primes pMMR tumors to ICI treatment. The investigators aim to test the combination of IT flu vaccine and ICI treatment in patients with non-metastatic pMMR CRC in a new trial. The hypothesis is that IT flu vaccine and ICI treatment will synergistically to induce cancer cell death.
This is an open-label, non-randomised FIH trial investigating the safety and tolerability of a novel ATMP, pTTL, composed of autologous tumour-draining lymph node-derived T cells stimulated in vitro with personalised cancer neoantigens. The neoantigens are selected through a process starting with next generation sequencing (NGS) of tumour material from the patient followed by selection of neoantigenic mutations using an in-house software, PIOR®. Selected neoantigen epitopes are expressed as recombinant proteins, NAG, and used to stimulate T cells to promote neoantigen-specific T cell expansion in vitro in pTTL production. pTTL is thus based on autologous cells stimulated with patient-specific neoantigens. In consequence, every pTTL product is unique and designated for use in one single individual. pTTL will be administered to patients with stage IV colorectal cancer (CRC) as a single intravenous dose.
Colorectal cancer (CRC) is one of the most common gastrointestinal tumors. According to the latest cancer report, the incidence and mortality rates of CRC are both ranked top 5 among malignant tumors worldwide and continue to rise. Patients who receive treatment in the early stage (stage I) have a 5-year survival rate of approximately 90%. However, for high-risk stage II and III colorectal cancer patients, the 5-year survival rate is only 40%-70%, and almost half of the patients experience postoperative recurrence and metastasis. Circulating tumor DNA (ctDNA) is a small fraction of total cell-free DNA (cfDNA) in peripheral blood circulation, carrying tumor-specific genetic and epigenetic information. It can usually be detected in the serum or plasma of tumor patients in peripheral blood. Studies have shown that methylation detection of plasma ctDNA can be used for predicting the efficacy and prognosis of tumor postoperatively, as well as for dynamic monitoring. Current methods for monitoring CRC recurrence include testing for carcinoembryonic antigen (CEA) in blood and periodic computed tomography (CT) scans. However, due to the low sensitivity of CEA and the radiation and cost limitations of CT examination, the disease status of postoperative CRC patients cannot be well-monitored. ctDNA is a promising biomarker for monitoring the recurrence and metastasis of CRC. Research results have shown that ctDNA can be detected in nearly all subjects before surgery, and the changes in ctDNA levels are related to the extent of surgical resection. The detection of ctDNA after surgery generally indicates recurrence within one year. ctDNA may be a more reliable and sensitive indicator than the current standard biomarker CEA, providing a window for early intervention. This multicenter, prospective, and randomized controlled cohort study uses a single-tube methylation-specific quantitative PCR (mqMSP) detection, which detects 10 different methylation markers and can quantitatively analyze plasma samples containing tumor DNA as low as 0.05%. This study will use the ctDNA methylation detection technology to conduct quantitative detection of ctDNA methylation in the plasma of enrolled patients, hoping to predict the recurrence and metastasis risk of patients at an earlier stage through ctDNA changes, and to explore the value of ctDNA detection in guiding postoperative follow-up for non-metastatic CRC.
This study is a non-randomized, 2-arm clinical trial comparing the effectiveness of two strategies for distributing FIT (fecal immunochemical test) kits in a community-based colorectal cancer screening program targeting African Americans (AAs). The main questions this study aims to answer are: - Does the on-site distribution of FIT kits result in higher return rates compared to direct mailing? - Which distribution strategy (onsite vs. direct mailing) is a more cost-effective approach for increasing colorectal cancer screening rates among underserved populations? Participants in the study will be African Americans who are eligible for colorectal cancer screening. Participants will be assigned to one of two groups: the on-site distribution group or the direct mailing group. In the on-site distribution group, participants will be given FIT kits at a designated Department of Motor Vehicle (DMV) service location. In the direct mailing group, participants will receive the FIT kits through the mail using the DMV database.
To measure the level of circulating tumor DNA (ctDNA) in the blood of colorectal cancer patients after 6 months of receiving therapy with regorafenib and XmAb20717 (also known as vudalimab). ctDNA is genetic material from tumor cells that can be found and measured in the blood
Pragmatic hybrid type 1 effectiveness-implementation (E-I) trial of a virtual cancer rehabilitation program: The study team will conduct a multi-center hybrid type I effectiveness-implementation study to examine the clinical effectiveness and implementation potential of an 8-week multidimensional virtual cancer rehabilitation intervention (CaRE@Home) for cancer survivors with identified cancer-related impairments on level of overall disability (primary outcome) and patient reported physical and social functioning, anxiety, work status, quality of life, and physiologic changes (secondary outcomes). The study team will conduct a multi-centre pragmatic randomized controlled trial (RCT) (Vancouver, Toronto, Saint John and St. John's) to evaluate effectiveness and using the CIFR, the study team will identify potential factors that may affect successful implementation and integration of CaRE@Home in different cancer settings.
