Filter by:The primary objective of this study is to compare the additive efficacy of SIM versus placebo in combination with leucovorin (folinic acid), irinotecan, and fluorouracil (FOLFIRI) as measured by improvement in progression-free survival (PFS) in participants with metastatic KRAS mutant colorectal adenocarcinoma who have progressed following a first-line oxaliplatin- and fluoropyrimidine-containing regimen.
Laterally Spreading Tumors (LST) are important precursosrs of invasive colorectal cancer. Endoscopic treatment has replaced surgery in most of the cases. Nevertheless, after conventional Endoscopic Mucosal Resection (CER), Local Residual Neoplasia (LRN) is an issue. Therefore, endoscopic follow-up and treatment are necessary. To decrease its occurrence, the risk factors of LRN shoudl be identified. Thereafter, in high-risk patients, other modalities of initial treatment including Endoscopic Submucosal Dissection (ESD) and surgical treatment, could be considered. The purpose of this prospective study is to identify risk factors associated with the presence of LRN after CER of LSTs.
The objective of this study is to compare the progression free survival (PFS), overall survival (OS), objective response rate (ORR), time to treatment failure (TTF), duration of response (DoR), quality of life, safety and tolerability of tivozanib in combination with mFOLFOX6 and bevacizumab in combination with mFOLFOX6.
The goal of the study is to conduct a randomized clinical trial to test several office-based strategies for improving colon cancer screening among individuals who are regular patients at 16 family practice physician offices in the state of Iowa. These offices are members of the Iowa Research Network (IRENE), a rural practice-based research network. The interventions to be tested are increasing in intensity from the usual care provided in the office, to physician chart reminders, mailed educational materials to patients, a fecal immunochemical test with postage-paid return envelope, and a telephone call designed to determine attitudes and barriers to screening, and to motivate subjects to get screened. Our main research questions are: 1)do attitudes toward CRC screening change after providing educational materials about CRC screening? 2)do mailed educational materials and a FIT, with or without a telephone reminder, result in increased rates of CRC testing with the FIT?
Study of Oxidative stress Markers (F2 Isoprostanes for lipid peroxidation, Carbonyl groups for protein peroxidation, 3 Nitrotyrosine for damage by nitrogens, and 8-Hydroxyguanosine for RNA peroxidation)in patients with colorectal cancer undergo surgical treatment (preoperatively during the intervention and postoperatively) and controls.
Growing evidence and understanding of an inherited component to several common, chronic diseases has led to an increase in the importance of information about family health history, and the integration of this information with other risk factors for common diseases, like lifestyle risk factors. The US Preventive Services Task Force (USPSTF) recommends the use of family health history as a routine genetic screening test for common diseases, as obtaining a complete family health history is the first step to identifying patients who are in need of intervention (e.g., intensive screening, lifestyle modification, preventative therapies, genetic counseling). The importance of integrating family health history with an individual's medical record will increase as our understanding of the genome evolves because it will be more essential to put detailed personal genetic information into a clinical context. Because of limited time during a typical primary care visit, and the concerns of primary care providers (PCPs) about their self-efficacy of estimating and providing guidance about risk, PCPs frequently do not obtain a family health history or provide individualized risk assessment. These issues highlight the need to leverage technology to collect these data independent of clinic visits, yet have these data interoperate with an individual's electronic health record (EHR). Telephonic interactive voice response systems (IVRS) and self-administered web-based tools are a low-cost, sustainable way of reaching out to primary care populations, independent of a visit. We propose to develop, implement, and evaluate a patient-reported, EHR-integrated personalized risk assessment module to provide tailored disease risk and risk reduction information. The Specific Aims of the proposed project are to: Aim 1: Develop a patient-reported, EHR-integrated, personalized risk assessment module to provide tailored disease risk and risk reduction information for four common diseases (breast cancer, colorectal cancer, coronary heart disease, and type II diabetes) for the patient and his/ her PCP. Aim 2: Measure the reach and effectiveness of this integrated risk assessment module by conducting a cluster randomized controlled trial (RCT) of adult primary care patients in the Brigham and Women's Primary Care Practice-Based Research Network. Aim 3: Evaluate facilitators and barriers to the adoption and implementation of this integrated risk assessment module. This project will further our understanding of how technology can be used to fill a gap in current clinical practice by facilitating the systematic collection of family health history and lifestyle risk factor data and integrating these data with an individual's EHR to personalize care in a variety of settings and for diverse patient populations. This work will use current national data standards for interoperability, and lessons learned from this project will be exportable to healthcare settings throughout the United States.
The purpose of this study is to investigate efficacy and safety of intra-operative chemotherapy with 5-FU for colorectal cancer patients receiving curative resection. The hypothesis is intra-operative intervention might be the best timing for cancer cells killing by cytotoxic agents, when most of residual cancer cells may get a rapid growth after tumor debulking and may become more chemotherapy-sensitive. A three-step procedure is designed for intra-operative chemotherapy with 5-FU of 1500 mg/m2, including step 1 of intraluminal 5-FU injection with 1000 mg/m2 at beginning of resection, step 2 of 200mg/m2 5-FU injection into portal vein system via mesentery vein after tumor removal and finish of bowel reconstruction, and step 3 of 300mg/m2 5-FU left into the abdominal cavity before incision closure. The controlled arm receive curative resection only. All the other treatments will stick to the guidelines.
Both ulcerative colitis and Crohn's colitis are associated with an increased risk of developing colorectal cancer (CRC). Although the increased risk of CRC in colitis patients is well established, several studies show that the risk varies widely between patients, depending on the presence of risk factors. Recently, several of these risk factors were implemented in the updated British guidelines for surveillance which are now used to determine surveillance intervals in our center. The new guideline recommends stratification of patients in a high, medium or low risk group depending on the presence of clinical and endoscopic risk factors and to adjust the surveillance interval accordingly. Although these guidelines provide a first step towards an individualized surveillance regimen, current data regarding risk factors for IBD (inflammatory bowel disease) -associated CRC are solely based on retrospective studies. Prospective data on the phenotype and genotype reliably predicting the risk of CRC is needed to further optimize surveillance in the future. Objectives: 1. To confirm established and identify new predictive factors for colorectal cancer in a prospective cohort of IBD patients undergoing regular surveillance. Dysplasia or colorectal cancer will be the primary outcome. 2. To provide evidence that mucosal healing results in a significant reduction of colorectal dysplasia/neoplasia in IBD patients and that this is associated with 5-ASA (5-aminosalicylic acid) or anti-TNF (tumor necrosis factor) maintenance therapy. 3. Study the expression of several tumor markers in biopsies, blood and faeces at baseline and determine whether expression of these markers can predict dysplasia or colorectal cancer development during follow-up.
Patients with advanced microsatellite unstable (MSI-H) colorectal cancer will be vaccinated with three so called frame shift peptides (FSPs), AIM2(-1), HT001(-1) and TAF1B(-1) combined with Montanide® ISA-51 VG. By this, an immune response directed against MSI-induced FSPs that are shared by the majority of MSI-H colorectal cancers can be induced. The aim is to show that vaccination against MSI-induced FSPs is safe and can induce or enhance immune responses against MSI-H colorectal cancer-associated antigens.
