Active clinical trials for "Colorectal Neoplasms"

Studies have shown that clear liquids containing carbohydrates are safe when given up to 2 hours before surgery and increase patient comfort before surgery. In the light of this information, this study aims to investigate the effects of preoperative oral carbohydrate administration on postoperative glucometabolic response, subjective well-being, quality of life, and surgical clinical outcomes in patients scheduled for colorectal surgery; planned as randomized-controlled, double-blind

This is a randomized, controlled trial aiming to assess the effects of preoperative education using stoma appliance on stoma self-care, quality of life, anxiety, and depression levels in colorectal cancer patients with a stoma.

This protocol seeks to develop a colonoscopy training program in Nigeria in order to increase the number of health care providers proficient in colonoscopy. The goal is to improve capacity for screening and early diagnosis of colorectal cancer (CRC) by training and expanding the healthcare workforce that is competent in endoscopy techniques. The project has three components, a needs assessment, simulation training, and training on live patients. The first part of this project determines the number of providers and endoscopy procedures currently performed in Nigeria, as well as patient access to facilities that have colonoscopy capabilities, through a mixed methods approach. Surveys, focus in-depth interviews with key stakeholders, and use geographic information system (GIS) modeling technology will be employed to perform a needs assessment. The second component of this project investigates whether a locally developed low fidelity (LF) simulation colonoscopy training model is an effective teaching, training, and assessment tool for skill acquisition and confidence compared to a high-fidelity (HF) colonoscopy model. The third component of this project is training healthcare providers on real patients who have an indication for colonoscopy. This project seeks to build capacity for endoscopy services in order to increase capacity for screening and early diagnosis of CRC. At the end of the project, it is expected the number of providers trained to perform colonoscopy in a resource limited setting like Nigeria will increase.

This clinical trial evaluates whether an adaptive text-message intervention is useful in helping survivors of colorectal cancers (CRC) eat more whole grain foods and less refined grain foods. Most CRC survivors don't achieve the recommended intakes of whole grains or fiber, even though there is strong evidence that a high-fiber diet rich in whole grains lowers the risk of death from CRC. Dietary interventions are a promising approach for reducing death from CRC, and text message interventions specifically are a promising tool for reaching diverse populations. This trial evaluates a text-message based dietary intervention that continuously adapts message content to be specifically tailored for the participant for increasing whole grain consumption.

The overall goal of this study is to develop a platform for both large-scale chemoprevention trials and real-world chemoprevention studies for colorectal cancer (CRC) prevention. The specific objectives of this proof of concept study are to: Evaluate the feasibility of a real-world chemoprevention agent (CPA) intervention (3-months of daily low-dose acetylsalicylic (ASA)) in participants at increased risk for CRC (one or more high-risk adenomas removed during colonoscopy) based on participant uptake, adherence (days taking CPA), and adverse events; Evaluate factors related to uptake and adherence of ASA using validated surveys and interviews.

The primary objective of GERONTE STUDY is to evaluate the effectiveness of the GERONTE, ICT-based, integrated care pathway to improve patient 6-month quality of life, in France. Study design is a stepped wedge randomised controlled trial. Clusters will be participating hospitals, comprising eight investigating sites in total (Figure 2). This is a stepped wedge of cross-over type. Patients included at each "step" are different individuals. The first "step" is a reference measurement where none of the clusters will implement the intervention. The investigating sites will be randomly drawn to determine the order in which they will implement the intervention, by "steps" of two months. The primary endpoint is the Quality of Life assessed by the EORTC QLQ-C30 (version 3.0) questionnaire at 6 months after GERONTE implementation. It has 3 sub-scores that will be analysed independently, with alpha risk adjustment.

This trial evaluates the effects a moderate-to-vigorous exercise intervention has on the bacterial make-up of the gastrointestinal tract (gut microbiota) in survivors of stage II-III colorectal cancer (CRC). Data shows that the gut microbiota composition and function may be drivers of CRC. High levels of exercise are associated with improved CRC prognosis and survival. While data suggests that exercise has the potential to influence gut microbiota composition and function, it is not known whether these effects contribute to improved CRC prognosis. This clinical trial evaluates the effects an exercise intervention has on gut microbiota and how these effects relate to CRC progression and patient-reported outcomes.

Colorectal cancer (CRC) screening program can reduce colon cancer-related mortality. Current CRC screening methods include stool occult blood and DNA testing, blood based tests and radiologic tests. Colonoscopy is considered the gold standard to detect colorectal neoplasms. Previous studies have estimated that cancer mortality to be 68% to 88% lower among persons who undergo screening colonoscopy than among those who do not. However, colonoscopy is an invasive examination, and 10% to 20% of patients fail to tolerate the procedure; therefore, greatly reduces the success rate of completion of colon examination. External controllability of capsule endoscope by means of an applied magnetic field is a possible solution to the maneuvering problem. However, there is no effective system with straight forward clinical applicability till now. This is ascribable to a lack of reliable magnetic instrumentation suitable for such a purpose. We have reported that magnetic field navigator (MFN) can effectively control the locomotion of capsule endoscope. We have demonstrated the feasibility and safety of magnetic-assisted capsule endoscope for the examination of upper gastrointestinal tract. In this study, we develop a magnetic-assisted capsule colonoscope by combination of the integrated circuit complementary metal-oxide-semiconductor imaging sensor, light-emitting diode, and magnetic control technology. This magnetic-assisted capsule colonoscope operation system includes a MFN Platform, high-end hand-controlled joystick, combined circuit component, control interface and software. This magnetic-assisted capsule colonoscope operation system creates a friendly operating environment for the operators, and may establishe a novel screening system for the colon.

An online-community based multidimensional rehabilitation program will be implemented for colorectal cancer survivors who have completed initial treatment. The intervention is based on the behavior change wheel and includes dietary intervention, exercise intervention, psychological support, and behavior management. Through various methods such as training, education, and motivation, the patient's ability, opportunities, and motivation will be increased, thereby promoting healthy behavior. Outcome measures include quality of life, fear of recurrence, and promotion of healthy lifestyle. The intervention period is six weeks, with evaluations conducted at baseline, week three of the intervention, and week three of the intervention.

The three main pathways of colorectal carcinogenesis are chromosomal instability, microsatellite instability (MSI) (15% of colorectal cancers =CRCs) and CpG island methylator phenotype (CIMP). MSI CRCs are associated with a better prognosis after curative surgery than CRCs without microsatellite instability (MSS). In contrast, MSI CRCs do not appear to benefit from adjuvant 5-FU chemotherapy, unlike patients with MSS CRCs. Nevertheless, the benefit of adjuvant chemotherapy with FOLFOX seems to be retained. The identification of prognostic markers in this subgroup of patients is therefore essential to decide on adjuvant chemotherapy, the efficacy of which is currently debated in MSI CRC. To date, there are very few data concerning metastatic MSI CRC. Metastatic forms are rare (about 5% of metastatic CRCs), but are thought to be associated with chemoresistance and poor prognosis. Nevertheless, data are very sparse and there are no data regarding the use of modern chemotherapies and targeted therapies in metastatic MSI CRC. Thus, it is important to characterize the chemosensitivity of metastatic forms. Clinical predictors of recurrence after curative CRC surgery are known but have only been studied in MSI CRC retrospectively. Similarly, many molecular and immunohistochemical factors, prognostic or predictive of response to adjuvant chemotherapy, have been recently identified in CRC (KRAS, BRAF, TP53, PI3KCA mutations, CIMP phenotype, SMAD4, immune response...). Most of these markers have been studied in all CRCs, but not specifically in the MSI CRC subgroup. All these prognostic and/or predictive biomarkers need to be better characterized in a large cohort of MSI CRCs.
