In the proposed project the investigators will evaluate two different follow-up approaches to improve low income patients' completion of initial and annual colorectal cancer (CRC) screening using the Fecal Immunochemical Test (FIT), the most sensitive FOBT. The purpose of this study is to compare the effectiveness of two distinct follow-up strategies to promote CRC screening: a prevention coordinator (PC) approach vs. an automated telephone reminder (ATR) system. The investigators will adapt a successful intervention tested in the Health Literacy and Cancer Screening Project by adding a follow-up strategy to the health literacy intervention. Specific Aims: The investigators Primary Aims are to: 1. Compare the effectiveness of the PC and ATR strategies to improve initial and repeat CRC screening. 2. Compare the cost effectiveness of the PC and ATR strategies for initial and repeat CRC screening. The investigators Secondary Aims are to: 3. Conduct a process evaluation of both follow-up strategies to investigate implementation and barriers 4. Determine if the effects of either strategy vary by patients' literacy skills. 5. Explore patient characteristics associated with CRC screening knowledge, beliefs, self-efficacy, and compliance over time between study arms.
This randomized research trial studies the Community-based Health Information Technology (HIT) Tools for Cancer Screening and Health Insurance Promotion (CATCH-UP) intervention in increasing cancer screening and prevention care in uninsured patients at community health centers. The CATCH-UP intervention may contribute to increased rates of insurance coverage, leading to improved cancer screening and prevention rates in community health care settings, and general recommended preventive care.
This study evaluates the effects of enhanced geriatric input on elderly patients undergoing colorectal cancer surgery. Half of the participants will received additional pre, peri and post-operative care from the geriatric team, while the other half will receive standard surgical care.
Background Hepatic metastases of colorectal cancer (MCC) is quite common and is a major source of morbidity and mortality. There has been evidence to show that hepatic arterial chemoembolisation using DC beads (drug eluting beads, 100-300μm) loaded with irinotecan (DEBIRI) showed improved overall survival when compared to systemic therapy (FOLFIRI), but being larger they have their limitations. New 70-150μm beads are recently available and currently there is limited data concerning its use. Safety of these beads have not been tested in local patients. Hypothesis / Aim To study the safety and pharmacokinetics of the smaller 70-150μm DEBIRI in a pilot study of 5 patients. The smaller 70-150μm beads will be able to deliver a more consistent and higher dose to tumoral tissue with a smaller systemic dose. Being smaller and less embolic, it will also be better tolerated. Patients will also be genotyped for their UGT1A1*28 and UGT1A1*6 polymorphism status as the latter genotypes are associated with decreased clearance of irinotecan and SN-38 in Asian patients. Methods Single centre, pilot study, prospectively recruiting 5 patients with unilobar disease, refractory to systemic chemotherapy The primary endpoints: 1. establish safety and toxicity profile of the irinotecan loaded DEBIRI beads 2. establish pharmacokinetics and systemic exposure of irinotecan and its active metabolite, SN-38. The secondary outcome measurements: 1. the incidence and severity of adverse events, liver function parameters and laboratory abnormalities; 2. response rate, 3. progression free survival 4. overall survival Clinical Significance This treatment modality has the advantage of directly delivering irinotecan to the liver metastases from colorectal cancer. This local mode of drug delivery may result in a higher intratumoral drug concentration and rapid tumour shrinkage leading to downstaging of the hepatic metastatic lesions. These therapeutic outcomes may also downstage patients to hepatic resection.
The purpose of this trial is to quantitatively assess the average amount of physical activity that patients are capable to perform while receiving regorafenib for the treatment of metastatic colorectal cancer. The assessment of this reference value, measured by CE (Conformité Européene)-certified pedometer and international physical activity questionnaire, will allow an estimation on the feasible amount of physical activity for patients in this therapeutic setting. This study is available for patients who are included in the global non-interventional study CORRELATE (Safety and efficacy of regorafenib in metastatic colorectal cancer patients; NCT01843400) in Austria.
Rationale: Colorectal cancer is the fourth most common cause of cancer death worldwide, estimated to be responsible for almost 610,000 deaths in 2008. Surgery remains the predominant curative treatment type for colorectal cancer, but has a major impact on the patient's wellbeing by demanding large amounts of metabolic reserves. This can lead to the development of frequently observed and severe postoperative complications. The most important complication after colorectal surgery is anastomotic leakage (AL), which has an incidence of 8-15% in the Netherlands. AL is associated with high short-term mortality rates of up to 40%. Even though many attempts have been made to reduce the incidence of this dreaded complication, none of these interventions have been successful so far. Despite proper patient selection and improvement in surgical techniques, the percentage of AL has been stable for years. Objectives: To investigate whether recently identified patient-specific factors can predict the occurrence of anastomotic leakage in patients undergoing elective surgery for colorectal cancer. Study design: Prospective observational study Study population: Adult colorectal cancer patients undergoing elective surgery. Main study parameters/endpoints: Primary endpoint: AL within 30 days postoperatively Secondary endpoints: Intestinal microbiome in fecal sample, I-FABP, SM22, Calprotectin, C-reactive protein(CRP), Citrullin, complement factors in blood, VOCs in exhaled air, COX-2 & MBL polymorphisms in buccal smear, L3-index & atherosclerosis measurements on CT-scans, SNAQ & MUST scores
Adenoma detection rate (ADR) is a validated marker for reducing the risk of interval colorectal cancer after a screening colonoscopy. Recent studies suggest that novel devices attached to the colonoscope tip may improve the ADR of doctors performing a screening procedure
The purpose of this study is to determine whether hemodynamic optimization with photoplethysmography (ClearSight, Edwards Lifesciences, Irvine, CA) during colorectal surgery could decrease the incidence of perioperative complications.
The purpose of this study is to exploratorily examine efficacy and safety in the participants with chemotherapy-naïve unresectable, advanced/recurrent colorectal carcinoma of Kirsten rat sarcoma-2 virus (KRAS) wild-type who have been treated with 6 cycles (2 weeks/cycle) of first-line mFOLFOX6 + panitumumab combination therapy and then assigned to two groups i.e., a group receiving 5-FU/LV + panitumumab combination therapy and a group receiving mFOLFOX6 + panitumumab combination therapy.
