Filter by:The purpose of this study is to evaluate, in terms of overall survival, the benefit of monoclonal antibodies in the start time of the diagnosis of advanced disease or administer a deferred basis after progression to treatment with chemotherapy alone. Initially expected target population was 1950 patients (pts), in 2015 protocol was ammended to 1028 patients, because the size was sufficient to evaluate the superiority of the use of monoclonal antibodies the start time of the diagnosis against deferred use, with HR of 0.8, power of 90% and an alpha of 0.05. Finally in July 2018, recruitment was completed with a total of 1104 patients enrolled.
Despite the success of surgery and chemotherapy among people with colon cancer, 30-50% of patients develop recurrent disease. Physical activity has emerged as a potential lifestyle intervention to reduce cancer recurrence and improve survival among people with colon cancer (CC). This pilot study aims to identify the dose-response effects of aerobic exercise on molecular and cellular pathways associated with physical activity and CC outcomes among patients with stage II and III CC.
The investigators are creating a data and specimen repository to study causes , early detection, prevention and treatment of colon and rectal cancer. The investigators are collecting data and specimens (blood, stool, urine and tissue) from people who have colon or rectal cancer, or who are risk for developing colorectal cancer or had normal colonoscopies. Data and samples are held in the repository until there are enough to be used for a large study or until there are new techniques that can be used to test them. The GI SPORE Program at the University of Michigan maintains a repository of specimens for colorectal diseases that the investigators hope will help fuel new research. The investigators hope that this work may lead to new treatments or earlier detection of colorectal cancer or improved diagnosis and treatment of other colon and rectal diseases.
This pilot phase I trial studies the side effects and best dose of CPI-613 when given together with fluorouracil in treating patients with colorectal cancer that has spread to other parts of the body and cannot be removed by surgery. CPI-613 may kill tumor cells by turning off their mitochondria. Mitochondria are used by tumor cells to produce energy and are the building blocks needed to make more tumor cells. By shutting off these mitochondria, CPI-613 deprives the tumor cells of energy and other supplies that they need to survive and grow in the body. Drugs used in chemotherapy, such as fluorouracil, 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. Giving CPI-613 with fluorouracil may kill more tumor cells.
Ideally, the postoperative inflammatory response is part of a well-orchestrated mechanism that contributes to tissue healing and rapid recovery. An exaggerated uncontrolled inflammatory response, however may lead to catabolism, tissue damage and organ failure. Omega-3 fatty acids may provide a means to alter cellular immune responses to the benefit of the patient. When omega-3 fatty acids are incorporated into membranes of inflammatory cells, they trigger intracellular signalling pathways that result in a less pro-inflammatory response. They modify gene and protein expression, modulate membrane protein activity and act as a reservoir for bioactive molecules. They also have a strong anti-inflammatory effect by mediating resolution of the inflammation. Furthermore, omega-3 fatty acids improve erythrocyte function, which is vital for an adequate microcirculation, tissue oxygenation and wound healing. The investigators hypothesize that the perioperative administration of intravenous omega-3 fatty acids results in a rapid incorporation in immune cells and erythrocytes, thereby reducing the postoperative inflammatory response and improving erythrocyte function in patients undergoing colorectal surgery.
The aim of the S-AVANT study is to collect additional data at 8 and 10 years median follow up of patients previously included in the AVANT trial from December 2004 to June 2007. Clinical data of the AVANT trial will be updated. Neither additional examination nor administration of any treatment will be performed on the patients. 330 centers in 34 countries participated to the AVANT trial (Australia, Austria , Belgium, Brazil, Bulgaria, Canada, China/Hong-Kong, Czeck Republic, Finland, France, Germany, Greece, Hungary, Israël, Italy, Japan, Korean Republic, Mexico, Netherlands, New Zealand, Norway, Panama, Poland, Portugal, Russia Federation, Singapore, South Africa, Spain, Sweden, Switzerland, Taïwan, Thaïland, United Kingdom, U.S.A). The AVANT study aiming at demonstrating superiority of bevacizumab in combination with FOLFOX-4 or XELOX compared to FOLFOX-4, did not show prolongation of DFS at 3 year when adding bevacizumab to chemotherapy in resected stage III colon cancer. Adverse events were consistent with the known safety profile of bevacizumab. However, more relapses and deaths due to disease progression have been observed in both bevacizumab arms. A more prolonged follow-up is necessary to assess overall survival and to evaluate long-term results and safety. Collection of additional follow-up data will start Q3 2014. Clinical data are to be collected at 8-year median follow-up (expected to be reached around Q2 2014) and at 10-year median follow-up (expected to be reached around Q2 2016). All analyses will be performed on an exploratory purpose only. An analysis at 8 years median follow-up and a final analysis at 10 years median follow-up will be performed in the main population (all randomized patients in the AVANT trial including patients lost to follow up or died).
This study seeks to learn more about the vitamin D receptor and its relationship to colon cancer. The Vitamin D receptor is found in colon cancer cells. When Vitamin D binds to the receptor in the cancer cells, it may stop cancer cells from growing abnormally and may cause cancer cell death. Vitamin D has been used in other research studies and information from those other research studies suggests that Vitamin D may help in the treatment of colon cancer. Participants will receive either high-dose vitamin D or standard-dose vitamin D. The study drug will be given 14-28 days prior to your surgery. The number of days will depend on when the surgery is scheduled.
The specific aim of the study is to determine the false negative rate of the Metabiomics Colon Polyp and Colorectal Cancer Assay for Cancer.
MOST is a longitudinal study whose aim is to test the hypothesis that frailty markers are better at detecting vulnerable patients and that they are a better "Adverse Events" predictive tool than the CGA (Comprehensive Geriatric Assessment) in older cancer patients referred for chemotherapy. The second hypothesis is that a brief screening tool based on a combination of some frailty markers and some used in the CGA would help the oncologist detect patients requiring a more complete geriatric assessment
This study involves standard combination chemotherapy treatment for colon cancer, 5-Fluorouracil (5FU), leucovorin and irinotecan (known as FOLFIRI), plus bevacizumab (Avastin). The study is designed to test the FOLFIRI regimen based on certain characteristics of a person's genetic makeup or "genes". Genes are made of DNA and determine not only inherited traits or appearance (hair and eye color, height, body type, etc.) but also play an important role in health and how the body responds to illness and treatments for those illnesses. In this study, the investigators will examine the relationship between a patient's genes (DNA), or "genotype", and how the patient's body breaks down and removes or "metabolizes" the anti-cancer drug irinotecan. Circulating blood level of irinotecan plays an important role in how well this drug works against a patient's cancer as well as the adverse side effects the patient may experience. The current standard dose of irinotecan was determined in clinical trials without knowing individual genotypes and thus does not take into account a patient's ability to metabolize irinotecan. This means that based on one genotype the current standard dose of irinotecan may be correct or based on other genotypes the standard dose could result in lower and possibly less effective blood levels and result in significant under-dosing of irinotecan. Based on genotype the patient will be assigned to one of the following doses of irinotecan: - 180 mg/m2 (standard dose) - 260 mg/m2 - 310 mg/m2 The purpose of this research study is to determine if dosing irinotecan based on genotype is effective and safe for patients with colon cancer. Patient genotype will be determined from a small sample of blood and a laboratory test or "assay" performed at UNC Laboratories. For the purpose of this study, this assay is new and considered to be "investigational". This means that the genotype assay used in this study has not yet been approved by the FDA for determining irinotecan dose levels in patients with colon cancer.
