Filter by:Improving personalized cancer treatments and finding the best strategies to treat each patient relies on using new diagnostic technologies. Currently, for colorectal cancer, the methods used to decide who gets additional post-surgery treatment are suboptimal. Some patients get too much treatment, while others do not get enough. There is a new way to explore if there is any cancer left in a patient's body using circulating tumor DNA (ctDNA) detected in blood samples. This can help decide who needs more treatment after surgery. Even though many tests have been developed, it has yet to be determined which test performs best at relevant time points. The GUIDE.MRD consortium is a group of experts, including scientists, technology, and pharmaceutical companies. The consortium is working on creating a reliable standard for the ctDNA tests, validating their clinical utility, and collecting data to help decide on the best treatment for each patient. FRENCH-MRD-CRC is the French study of the european GUIDE.MRD project.
This is an open-label Phase II trial that will investigate the use of neoadjuvant CAPEOX chemotherapy with Atezolizumab followed by surgery and adjuvant chemotherapy for patients with localized resectable pMMR adenocarcinoma of the colon with a target accrual of 30 patients. The investigators will explore if appropriately timed neoadjuvant CAPEOX with anti-PD-L1 mAb (Atezolizumab) can be administered safely and feasibly for 12 weeks, and that this combination will lead to improved clinical response associated with enhanced numbers of immune cells in surgically resected colon tumors. Participants will receive 4 cycles of atezolizumab in combination with 4 cycles of CAPEOX (atezolizumab will be administered prior to chemotherapy) before standard of care surgical resection. Each cycle of neoadjuvant therapy is 3 weeks. Following surgery, participants still considered to be at high-risk of recurrence (per NCCN guidelines) will receive further adjuvant chemotherapy (mFOLFOX6 or CAPEOX),for 6 and 4 cycles respectively (for a total of 12 weeks), based on the discretion of the treating oncologist/investigator. Participants will be followed up for an EFFICACY follow-up phase every 2 months during the first 6 months after surgery (months 1, 3, 6) and thereafter participants will enter a SURVIVAL follow-up phase and will be seen every 6 months starting at month 12 until month 36. During this the efficacy and survival follow up visits blood samples will be obtained for purposes of obtaining circulating DNA and stool and optional blood samples for storage for future exploratory analysis. Additionally, during these follow up visits, participants will be asked to complete quality of life questionnaires
This Phase II/III trial will evaluate the what kind of chemotherapy to recommend to patients based on the presence or absences of circulating tumor DNA (ctDNA) after surgery for colon cancer.
The aims of this study are to evaluate if an intensified adjuvant treatment with FOLFOXIRI could increase the rate of cases with undetectable ct-DNA after chemotherapy and to evaluate if a further adjuvant treatment with Trifluridine/Tipiracil could increase the rate of cases with undetectable ct-DNA and therefore improve DFS in a population at high-risk of relapse. An additional target-driven cohort of HER2+ RAS wild-type colon cancer patients will be assessed for ct-DNA clearance after a tailored treatment with Trastuzumab and Tucatinib plus FOLFOX
According to general medical guidelines, adjuvant chemotherapy is used after curative resection of high-risk stage II or III primary colon cancer. However, there exist limitations using clinical trial data acquired from highly selected subjects in a controlled environment. For example, patients aged over 70 years old were in many cases excluded from clinical trials resulting in insufficient data on the efficacy of therapies including oxaliplatin in aged patients, and the source data of the medical guidelines did not fully reflect the conditions of Korean patients. In addition, suggestions are continuously being submitted for existing therapies with modified administration periods and methods with the aim to search for the optimum effect over side effects. Discussions are also held on meta analyses results that imply the need to apply slightly different approaches through small groups of patient and disease factors. As there are more diverse adjuvant therapy protocols that can be applied to post-surgery colon cancer patients, it is necessary to figure out the patterns of adjuvant chemotherapies actually used in Korean medical practices. Also, in order to complement the limitation of external validity of the existing base clinical data, a multifaceted exploratory analysis will be conducted by making follow-up observations on patterns, prognosis results, quality of life, adverse effects, etc. of post-surgery adjuvant chemotherapies actually used in around 30 sites in Korea under the noninterventional observational study conditions.
This phase Ib trial studies side effects and best dose of dasatinib in preventing oxaliplatin-induced peripheral neuropathy in patients with gastrointestinal cancers who are receiving FOLFOX regimen with or without bevacizumab. Drugs used in chemotherapy, such as leucovorin, fluorouracil, and oxaliplatin (FOLFOX regimen), work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. However, the buildup of oxaliplatin in the cranial nerves can result in damage or the nerves. Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Blocking these enzymes may reduce oxaliplatin-induced peripheral neuropathy.
This phase I/II trial studies the side effects and how well encorafenib, binimetinib, and nivolumab work in treating patients with microsatellite stable, BRAFV600E gene-mutated colorectal cancer that has spread to other places in the body (metastatic). Encorafenib and binimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving encorafenib, binimetinib, and nivolumab may work better in treating patients with colorectal cancer compared to standard treatments.
Background: 1. . The incidence and mortality of colon cancer are high in China and in the world. 2. . The treatment of many patients in the real world is not standardized, and there are problems such as over-treatment or under-treatment. To explore the adjuvant treatment of colon cancer in the Chinese population, this study will retrospectively analyze real-world data on adjuvant therapy for colon cancer in Chinese patients after radical surgery. The purpose of research: 1. . Current status of adjuvant therapy for stage II-III colon cancer in the real world: chemotherapy regimen, chemotherapy time, efficacy, safety, etc. 2. . Comparison of efficacy and safety of different adjuvant chemotherapy time (<3 months vs. >=3 months) in high-risk stage II and III colon cancer patients in the real world 3. . Comparison of efficacy and safety of different adjuvant chemotherapy regimens (XELOX vs. FOLFOX) in high-risk stage II and III colon cancer patients in the real world
The purpose of this study is to determine if dMMR and/or POLE exonuclease domain mutant stage III colon cancer patients gain clinical benefit (i.e. improvement in disease free and overall survival) from PD-L1 inhibitors after standard fluoropyrimidine-based adjuvant chemotherapy. Avelumab binds PD-L1 and blocks the interaction between PD-L1 and PD-1. This removes the suppressive effects of PD-L1 on anti-tumour CD8+ T cells, resulting in the restoration of cytotoxic T cell response. The rationale of giving Avelumab after standard adjuvant chemotherapy to this well-defined, molecularly-selected, group is based on the fact that dMMR and POLE exonuclease domain mutant CRCs have a highly and ultra-mutated genetic profile, respectively, thus leading to a high number of neo-antigens with associated over expression of immune checkpoint related proteins. This profile is expected to be highly responsive to checkpoint inhibition as suggested by data of PD-1 inhibitors in dMMR/MSI-H metastatic CRCs. If this study meets the primary endpoint, using Avelumab in the adjuvant setting following standard chemotherapy would become the standard of care for patients with dMMR and/or POLE exonuclease domain mutant colon cancers. Furthermore, given the availability of molecular markers for patient selection, funders of healthcare would be more likely to fund this treatment. This study also provides a unique opportunity to conduct translational research analyses on pre- and post-treatment tumour tissue samples and blood samples from dMMR or POLE mutant CRC patients treated with the checkpoint inhibitor Avelumab.
This research study is comparing two standard of care treatment options based on blood test results for participants who have metastatic colon cancer. The names of the potential treatments involved in this study are: - Active surveillance - FOLFIRI treatment - Nivolumab treatment - Encorafenib/Binimetinib/Cetuximab treatment - Trastuzumab + Pertuzumab
