Filter by:The overall goal of the COACH study is to conduct a comparative effectiveness trial to assess the effectiveness of trained, participant-designated health coaches versus traditional health education efforts on cancer screening among African American older adults. We hypothesize that members of older adults' extended families can be trained to be effective coaches who support them through the cancer control spectrum, i.e., prevention, screening, diagnosis and treatment. This research objective is guided by the theoretical model of the PRECEDE-PROCEED conceptual framework that has been widely adopted in health promotion. The target jurisdictions for this study are Baltimore City (BC) and Prince George's County (PGC), Maryland. The study is anchored in community-based participatory research (CBPR) principles, involving community members in all its phases. The CBPR component is guided by Community Advisory Groups (CAGs) representing key stakeholders in the two jurisdictions. The CAGs are essential in determining the questions included in data collection instruments, mechanisms of recruitment, interpretation of findings, and dissemination of results within the target communities.
The purpose of this study is to assess the impact of probiotic administration (Saccharomyces boulardii) on patients undergoing colorectal resections comparing to the routine protocol by assessing: (1)intestinal microbiota modulation using RT-PCR to measure cytokine in the mucosa; (2) assess postoperative complications, mainly infectious and mortality, as well as length of hospital stay
Rehabilitation program improves operative results following conventional open colorectal surgery. Very few data are available on such program in laparoscopic colorectal surgery.
This observational, multicenter, retrospective/prospective study will evaluate the use of Avastin (bevacizumab) in clinical practice in patients with metastatic colorectal cancer. Patients having initiated first-line treatment with a fluoropyrimidine-based chemotherapy and Avastin will be followed for up to 15 months.
The purpose of this study is to compare the efficacy and safety of TAS-102 versus placebo in patients with refractory metastatic colorectal cancer.
Adenoma detection rate (ADR) is a quality indicator of colonoscopy performed for colorectal cancer screening. Population studies have shown that traditional air colonoscopy fails to eliminate post screening colonoscopy cancers or cancer mortality in the proximal colon. The investigators aim to establish the superior effectiveness of combining chromoendoscopy with the water exchange method in detecting more proximal diminutive adenomas during screening colonoscopy in sedated Veterans. An improved adenoma detection rate associated with optical colonoscopy will minimize the risk of missed lesions. The improvement may translate into a remedy for the limitations of screening colonoscopy in the proximal colon, e.g. a higher adenoma detection rate may minimize the burden of post screening colonoscopy interval colorectal cancers among the veteran population.
The clinical benefit of resection of the primary tumour in patients with synchronous unresectable metastases is not known. In the literature studies usually describe retrospective selected patients with synchronous metastases treated with or without resection of the primary tumour. All these studies are biased in patient selection and there are no prospective randomized studies on this topic. In patients with few or absent symptoms of the primary tumour, arguments both in favour and against initial resection have been presented, and therefore a randomized trial is warranted. Although recent publications suggest that resection of the primary tumour in synchronous metastasized colon cancer patients might not be necessary, this appears to be based on feasibility and not on clinical outcome. Several studies comparing large groups of patients with or without resection of the primary tumour suggest an improved survival when the primary tumour is resected. A potential benefit of resection of the primary tumour is to prevent complications of the primary tumour during chemotherapy treatment or during later stages of the disease. A recent analysis of the CAIRO and CAIRO2 data showed that metastatic colon cancer patients who had a resection of the primary tumour prior to study entry, had an improved survival compared to patients without a resection of the primary tumour. However, these patients were selected after the primary tumour was resected and therefore these results are not corrected for surgical morbidity and mortality. The investigators here propose a randomized trial in order to demonstrate that resection of the primary tumour does improve overall survival.
No ideal serum biomarker currently exists for the early diagnosis of colorectal cancer (CRC). Therefore, it is urgent that accurate and reliable serum biomarkers be identified.
The goal of the investigators study is to investigate the role of a hormone named Activin A (ActA) in the development of the skeletal muscle atrophy caused by cancer. According to the investigators hypothesis, ActA could be released by the tumor and activate a muscle atrophy gene program. To answer this question, the investigators plan first to compare circulating levels of ActA in cancer patients with and without cachexia. In a second step, the investigators would like to assess whether ActA circulating levels are predictive for the development of cachexia and short survival.
The purpose of this registry is to collect information about patients in which a pouch has been created to improve in the future the quality of the surgery of the pouch.
