Filter by:This study aims to develop a highly sensitive, specific, and cost-effective blood assay for early detection of colorectal adenomas and cancer, using advanced machine learning and state-of-the-art biological analyses.
Colorectal cancer (CRC) once predominantly affected older individuals, but in recent years has witnessed a progressive increase in incidence among young adults. Once rare, early-onset colorectal cancer (EOCRC, that is, a CRC diagnosed before the age of 50) now constitutes 10-15% of all newly diagnosed CRC cases and it stands as the first cause of cancer-related death in young men and the second for young women. This study aims to detect EOCRC with a non-invasive test, using a blood-based molecular assay based on microRNA (ribonucleic acid)
This study will develop an assay to predict disease recurrence in patients with stage II/III CRC after receiving adjuvant chemotherapy, using genome-wide DNA methylation.
Approximately two-thirds of all colorectal cancer patients undergo surgery with the aim of curing them. However, despite the surgery, 20-25% of them experience relapse. It is possible to reduce the risk of relapse with chemotherapy, but as chemotherapy is associated with significant side effects, it is only given to patients at high risk of relapse. Currently, the risk is assessed based on an examination of the removed tumor tissue. In a previous research project, blood samples were taken after patients' surgery and examined for the presence of circulating tumor DNA (ctDNA). When cancer cells in solid tumors die, they release DNA, which can be detected in the blood. DNA in the blood has a half-life of less than 2 hours, so if ctDNA is found in a blood sample taken, e.g., 14 days after surgery, the patient most likely still has cancer cells in their body. The results show that if a patient has ctDNA in their blood after surgery, the risk of relapse is high. The presence of ctDNA in the blood has the potential to be a better indicator of the risk of future relapse than the tumor examination used today. Therefore, ctDNA analysis has the potential to become a marker that will be used in the future clinical setting for monitoring colorectal cancer. The overall objective of this study is to confirm that ctDNA found in a blood sample after intended curative treatment for CRC is a marker of residual disease and risk of recurrence and is applicable in clinical practice.
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.
This is a multi-site epidemiological study designed to monitor circulating tumor DNA (ctDNA) status in participants with Stage II (high risk)/III colorectal cancer (CRC) following resection/prior to adjuvant chemotherapy (AdCTx), during the course of AdCTx and for a period of 630 days thereafter, according to CRC stages and disease characteristics. Participants receive no therapeutic intervention as part of this study. This study will identify participants who might be potential candidates for the clinical trial BNT122-01 (NCT04486378), a study of RO7198457 after completion of standard AdCTx in this patient population. Based on the eligibility criteria for that trial, this study will identify participants with confirmed Stage II (high risk)/III CRC that are positive for ctDNA after resection and are therefore at high risk of disease recurrence to enrich the BNT122-01 study cohort. These participants will have the option to enter screening for BNT122-01 at Screening Visit 2 of that trial if they meet the eligibility criteria of BNT000-001 during screening. Data from the assessments from BNT000-001 will be carried across to the BNT122-01 trial where feasible.
This is a multi-site, open-label, Phase II, randomized, trial to compare the efficacy of RO7198457 versus watchful waiting in patients with circulating tumor DNA (ctDNA) positive, surgically resected Stage II/III rectal cancer, or Stage II (high risk)/Stage III colon cancer.
Fusobacterium nucleatum (Fusobacterium nucleatum, Fn) has been identified as an independent risk factor for recurrence of colorectal cancer. In this study, oral metronidazole would be used to reduce the abundance of Fn in patients with high Fn, so as to explore whether oral metronidazole can improve the efficacy of postoperative chemotherapy in patients with colorectal cancer.
