Filter by:This phase I trial studies the side effects and best dose of regorafenib when given together with ipilimumab and nivolumab in treating patients with microsatellite stable colorectal cancer that has spread to other places in the body (metastatic) and remains despite chemotherapy treatment (resistant). Regorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as ipilimumab and 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 regorafenib, ipilimumab and nivolumab may slow the tumor growth and/or shrink the tumor size in patients with colorectal cancer.
In 2018, colorectal cancer is the third most common malignant tumor in terms of morbidity and second mortality in the world. Surgical resection is still the main treatment for colorectal cancer.With the introduction of the ERAS, the latest international and domestic guidelines for fasting before surgery all advocate shortening the fasting time. For example, 2 hours before surgery, oral take cleared fluids, including water, sugar water, fruit juice, tea and black coffee (without milk) is allowed.Solid food can be consumed 4 hours before surgery, and oral diet should be resumed as soon as possible after surgery. Changes in diet, nutritional status, and physical activity are closely related to the incidence of colorectal cancer. Therefore, we believe that the intestine may be very sensitive to different fasting times during the perioperative period. Prolonging the fasting time may improve the prognosis by improving postoperative insulin resistance, reducing inflammation and protecting anti-tumor immune function in patients with colorectal cancer.Prolonged fasting time seems to be contrary to the results of some studies, and whether it is applicable to patients with tumor surgery is unclear. Therefore, there is an urgent need to conduct large-scale, prospective, randomized controlled clinical studies to clarify the most suitable perioperative fasting strategy (including composition, interval, and amount) for cancer patients, which can not only reduce surgical stress and speed up postoperative rehabilitation,reduce postoperative metastasis and recurrence and improve mid- and long-term prognosis.
Only 59% of Alaska Native people have been adequately screened for colorectal cancer (CRC) despite having the highest reported incidence of CRC in the world. A new at-home multi-target stool DNA screening test (MT-sDNA; Cologuard®) with high sensitivity for pre-cancerous polyps and CRC is now available. MT-sDNA has not been tested for feasibility or acceptability within the Alaska tribal health care delivery system, and it is unknown whether use of this new test will increase Alaska Native CRC screening rates. The long-term study goal is to improve screening and reduce CRC-attributable mortality. The objective of this application is to test the effectiveness of MT-sDNA for increasing CRC screening in Alaska Native communities using a mixed methods, community-based participatory research (CBPR) approach. The study will be conducted in collaboration with regional Tribal health organizations responsible for providing health care to geographically remote Alaska Native communities. Although the proposed implementation strategy is evidence-informed and promising, it is novel in that MT-sDNA has not been evaluated in the tribal health setting or among rural/remote populations. Using the Social Ecological Model, the research will be multi-level, examining influence on patients, providers, and tribal health organizations (THOs). This research study will pursue two specific aims: (1) Identify patient-, provider-, and system-level factors associated with CRC screening preferences, uptake, and follow-up; and (2) test the effectiveness of graded intensity MT-sDNA intervention in the Alaska Native community setting. For the first aim, focus groups with Alaska Native people who are not adherent to CRC screening guidelines and interviews with healthcare providers will be used to identify factors for future intervention. For the second aim, a three-arm cluster randomized controlled trial (high intensity with patient navigation, medium intensity with mailed reminders, usual care) will provide evidence on the MT-sDNA usefulness (MT-sDNA sample quality and neoplastic yield) as well as the first data on MT-sDNA follow up adherence rates in the Alaska Native population, which will inform plans to scale-up the intervention model. This research has the potential to sustainably improve public health by increasing CRC screening rates among a rural/remote tribal population as well as provide a model for other integrated health systems that provide care to high-risk or underserved populations in the U.S. and worldwide.
This is a global, randomized, double-blind, placebo-controlled, multicenter phase 3 clinical trial to compare the efficacy and safety of fruquintinib plus best supportive care (BSC) versus placebo plus BSC in participants with refractory metastatic colorectal cancer (mCRC). 691 participants were randomized to one of the following treatment arms in a 2:1 ratio, fruquintinib plus BSC or placebo plus BSC.
In this study, participants with locally advanced rectal cancer patients will be treated according to MMR/MSI status. There will be two cohorts in this study: Cohort A and Cohort B. For Cohort A, dMMR or MSI-H patients will receive 4 cycles of neoadjuvant Pd1 antibody Sintilimab,followed by one of the following treatments: (1) surgery and adjuvant treatment, (2）another 4 cycles of sintilimab, followed by radical surgery or observation (only for cCR) . For Cohort B, pMMR/MSS/MSI-L patients will be randomized to receive neoadjuvant chemoradiotherapy ± four cycles of Pd1 antibody Sintilimab，followed by one of the following treatments: (1) curative surgery and four cycles of adjuvant chemotherapy;(2)four cycles of chemotherapy then observation (only cCR after neoadjuvant therapy)
This study will test the effectiveness of an outreach strategy to increase colorectal cancer (CRC) screening in African Americans. The investigators will recruit 250 African Americans ages 45-64 years who are not up-to-date with CRC screening or have never been screened, with the goal to evaluate screening knowledge, behavior, and intervention effects on CRC screening outcomes. Participants will be randomly assigned to the TUNE-UP intervention or a control group. The TUNE-UP intervention arm will utilize a community health advisor (CHA) to encourage return of stool blood testing kits through cell phone outreach. The control group will receive educational materials about CRC screening plus a resource list but no CHA counseling support or cellphone / text contact. The primary study outcome is receipt of CRC screening (colonoscopy or FIT) following the intervention. The secondary outcomes will include CRC screening knowledge, self-efficacy (confidence to receive CRC screening), intention to screen, and follow-up in the case of an abnormal test result. The research objective is to test the CHA intervention effectiveness for promoting stool blood testing as a preferred screening test in an under-screened African American population.
PD1 antibody is now recommended for dMMR/MSI-H metastatic colorectal cancer patients as second line. Chemoradiotherapy is standand treatment for locally advanced rectal cancer and is also recommended as an alternative choice for unresectable locally advanced colon cancer. Thus, this study will investigate the efficacy and toxicity of combination strategy using PD1 antibody and chemoradiotherapy for dMMR/MSI-H locally advnaced colorectal cancer patients.
This phase II trial studies how well TAS-102 and oxaliplatin work in treating patients with stage IV colon cancer. Drugs used in chemotherapy, such as TAS-102 and oxaliplatin, 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.
A phase Ib, open-label platform study of select drug combinations chosen in order to characterize safety and tolerability of each treatment arm tested and to identify recommended doses and regimens for future studies.
Introduction: Early detection of certain types of cancer significantly increases the likelihood of successful treatment and reduces mortality from these causes. However, the use of screening and the early detection of selected tumors such as colorectal cancer (CRC) are lower than those expected in our country. The objective of this project is to evaluate the effectiveness of a multicomponent strategy that improves the screening and early detection of CRC in the population at risk of Primary Health Care Clinics (PCCs) of the public health system. Population: people leaving in the catchment area of 10 selected primary care clinics from the public health system in the province of Mendoza, Argentina. Design and methods: a Randomized clinical study by clusters. 10 PCCs will be included: 5 will be randomly assigned to receive an intervention to increase the CRC screening rates (improvement cycles) and 5 to the control arm (usual care). 150 participants will be included in each PCCs, in total, 1500 participants. Intervention: An innovative vision is proposed, which combines a participatory and dynamic methodology based on improvement cycles. This approach includes the implementation of participatory learning sessions for health providers, involving the effectors of the design of the intervention. In the intervention branch at least 3 workshops (sessions) will be held with the members of the care system, in order to identify opportunities for improvement oriented to the design and application of an innovative intervention based on best practices. Each one of the sessions will constitute an analysis of the improvement cycle, following the following steps: 1) Selection of participants of the initial workshop; 2) Development of work model based on bibliographic review and initial qualitative phase; 3) Initial workshop with effectors for training in continuous improvement, objectives, interventions and data collection; 4) Learning workshops to discuss results, applicability of interventions and modifications to the work plan; 5) Closing session to evaluate preliminary results and discuss continuity of interventions beyond the project. Outcomes: 1) Percentage of the population at risk that completes the screening; 2) Percentage of the population classified as at habitual risk or increased by risk factors.
