Filter by:The purpose of this study is to establish the safety and tolerability of BKM120 when combined with mFOLFOX6 and to define the maximum tolerated dose of BKM120 in this combination in advanced solid tumors including metastatic pancreatic cancer.
Matrix metalloproteinases (MMPs) have been shown to be involved in cancer biology. Significant expression of MMP-7 (matrilysin) in colorectal cancer is mainly associated with metastatic disease even though it is expressed in most tumor states. Our purpose is to analyse MMP-7 in bowel and lymph nodes of different tumor stages and to evaluate its expression as a potential biomarker of cancer disease in patients surgically treated for benign and malignant colorectal tumors. Tumoral tissue, lymph nodes and serum samples from recruited Patients plus serum samples from healthy volunteers are analysed for matrilysin expression by histology, immunohistochemistry, ELISA and Western blotting. If Matrilysin increases with increasing dysplasia and cancer disease stage in tumor tissue as well as in the regional lymph nodes it might be used as a complement in investigating suspected locally advanced cancer.
This is a single-centre, single-arm open-label proof-of-concept study to analyze the imaging (DCE-CT,CEUS and Quantitative US) effects of neoadjuvant bevacizumab and SBRT on colorectal metastases to the liver. Patients will receive 2 doses of bevacizumab 5mg/kg IV prior to SBRT. The second dose of bevacizumab will be given 2 weeks after the first dose of bevacizumab and within 48 hours of starting the first dose of SBRT. The SBRT prescription dose will be up to 60 Gy in 6 fractions, delivered on alternating weekdays for 2 weeks. Total SBRT dose will be determined by size of target lesion, liver sparing and organs-at-risk dose constraints. DCE-CT, CEUS and Quantitative US will be performed within 7 days prior to the first dose of bevacizumab, after the second dose of bevacizumab and within 7 days of completing SBRT.
The proposed study seeks to investigate the impact of a culturally targeted print educational intervention on rates of colorectal cancer (CRC) screening via colonoscopy among Hispanics. If, as expected, the addition of culturally targeted materials to best clinical practices as compared to a) best clinical practices plus standard materials or b) best clinical practices alone leads to higher rates of CRC screening via colonoscopy then the culturally targeted print educational materials can be easily disseminated among this rapidly growing minority group who have low rates of CRC screening and whose disease is detected at later, less curable stages.
This study is being done to see if teaching physicians and people who are at least 50 years old and have not been screened within guidelines for colorectal cancer about the importance of colorectal cancer screening will increase screenings for colorectal cancer. The researchers want to understand what ways will work best to motivate and educate both patients and the doctors and nurses who care for them.
Objective: To evaluate the role of regional lymphadenectomy in patients with colorectal cancer liver metastasis. Background: Lymph node status is 1 of the most important prognostic factors in oncologic surgery; however, the role of lymph node dissection remains unclear for colorectal cancer liver metastasis.
Participants will be recruited from the United States and Australia to take an online survey about colon cancer screening or prostate cancer screening. Individuals selected for both the prostate cancer survey and the colon cancer study will be randomized to take one of three survey types - balance sheet, rating and ranking or conjoint analysis. These surveys will help participants clarify their values and opinions about screening options for colon cancer or prostate cancer. Participants' responses to the online survey are measured at one point in time - the time at which the participant takes the survey.
The purpose of this study is to determine if the adherence to screening in first grade relatives of patients with CCR is higher than optical colonoscopy.
This multicenter, prospective, observational study will evaluate the efficacy and safety of Avastin (bevacizumab) in first-line therapy in elderly patients with metastatic colorectal cancer. Data will be collected from eligible patients for24 months.
Variations in participation to the colorectal cancer screening seems to reveal social and geographical inequalities. Our study will investigate whether patient navigation could increase the participation to the colorectal cancer screening and in the same time, reduce the social inequalities.
