Filter by:The study attempts to quantify the relative risks for mortality, anastomotic leakage and other early and late postoperative complications, recurrence rate, cancer-specific survival, recurrence-free survival after colorectal surgery for patients with colorectal cancer depending on the localization of the tumor.
The aim of this study is to evaluate the potential efficacy and safety of nitazoxanide in patients with metastatic colorectal cancer.
This multi-site, Phase 1/2 clinical trial is an open-label study to identify the safety, pharmacokinetics, and efficacy of a repeated dose regimen of NEO212 for the treatment of patients with radiographically-confirmed progression of Astrocytoma IDH-mutant, Glioblastoma IDH-wildtype, and the safety, pharmacokinetics and efficacy of a repeated dose regimen of NEO212 when given with select SOC for the treatment of solid tumor patients with radiographically confirmed uncontrolled brain metastasis. The study will have three phases, Phase 1, Phase 2a and Phase 2b.
After introducing a nationwide screening program for colorectal cancer (CRC) in Denmark, more cases of early-stage CRC are being detected. Cancers in the earliest stages are often removed locally, either during the diagnostic colonoscopy or through planned minimally invasive surgery. This early detection of cancer, and thereby an improved prognosis, is a positive feature but has also introduced a new clinical dilemma. Is the patient fully cured by the local resection, or do they need further surgery? Whether further surgery is recommended at the Multi-Disciplinary Team (MDT) board meeting depends on the outcome of specific criteria from the histopathological assessment of the locally removed specimen. The presence of these criteria does not, however, translate directly into the presence of residual disease - merely into a theoretically increased risk. In Denmark, after surgery, the fraction of cases with residual disease has been around 15% for many years. In the remaining 85% of cases, local removal alone was curative - and the surgery appears excessive. Investigating blood samples for the presence of circulating tumor DNA (ctDNA) is a new and promising method for cancer detection. The method utilizes that cancer cells release ctDNA into the circulation. ctDNA detected in blood drawn from a patient a few days after local removal of a tumor indicates that residual disease is present and further treatment, such as surgery, is needed. The purpose of this study is to investigate, whether analyses of ctDNA can correctly identify patients with residual disease after local removal of early CRC. If this identification proves accurate, many patients can be spared further surgery.
This study is to evaluate the safety and tolerability of RMC-9805 in adults with KRAS G12D-mutant solid tumors.
The purpose of this study is to look at mental health services for adults with depressed mood who were diagnosed with cancer at the age of 65 or older. This study will compare the usual approach for connecting older adults with depressed mood to mental health services with the Open Door for Cancer (OD-C) approach. We will find out if the OD-C approach is practical and useful for cancer patients who participate in the intervention and for providers who see or treat cancer patients.
The purpose of this study is to determine the safety and feasibility of VGT-309 for the visualization of colorectal tumors in real-time using near-infrared (NIR) fluorescence endoscopy. In addition, signatures of 50+ biomarkers will be evaluated in biopsies using CODEX multi-plexing.
This is a patient registry for all cases of pre-neoplastic or early neoplastic digestive tract lesions treated with curative intention by endoscopic submucosal dissection (ESD) technique.
The effect of mailing FIT with the invitation on participation and colonoscopy rates will be evaluated in a randomized controlled trial conducted in the Centre-Val de Loire (CVL) region, involving 64,000 people from the population eligible for colorectal cancer population-based organised screening program (CRC-PBOSP). In the "C" control group, invitations, test delivery and reminders will be carried out in accordance with the CRC-PBOSP rules at the time of the study. Intervention group "B" will evaluate two experimental modes of invitation with direct home mailing of the test: - Method "B1": invitation with test sent to home without prior information letter - Method "B2": information letter followed by invitation with test sent home, designed to optimize participation by first-time subjects (aged 50-51) invited to the CRC-PBOSP for the first time. Ancillary studies will focus 1/ on acceptability of this intervention (qualitative study on a few general practitioners, gastroenterologists and invitees), 2/ on social and geographical inequalities of participation on a subsample of individuals included in EXPEDIT study using ecological indices (EDI, SCALE).
We first collect tumor tissue and adjacent tissue to peform the WES sequencing, then collect blood after postoperative surgery 1, 3. 6, 9, 12, 18, 24 month to detect ctDNA.
