Active clinical trials for "Colorectal Neoplasms"

You are being asked to take part in this study because either you are a survivor who has a previous history of colorectal cancer or an MD Anderson patient who had a precancerous colorectal polyp or you have a previous history of colorectal cancer, and you have a current adult body mass index (BMI) score of 25 or higher. The BMI score is used as an indicator of the level of body fat, based on height and weight. The goal of this clinical research study is to learn if eating canned, pre-cooked beans can help improve the levels of healthy bacteria in the digestive system and reduce the effects of obesity on cancer risk. This is an investigational study. Up to 80 participants will be enrolled in this study. All will take part at MD Anderson.

A Phase I/IIa Dose-Escalation Study Evaluating the Safety, Tolerability and Efficacy of LEAC-102 in Combination with FOLFOX + Bevacizumab/Cetuximab in Subjects with Advanced Colorectal Cancer

Colorectal cancer is the fourth most common incident cancer and the second most common cause of cancer death in the United States, with approximately 150,000 new cases and 57,000 deaths per year. High calcium intake and magnesium may protect against colorectal cancer and adenoma, however, results have been inconsistent. We found that genetic makeup, associated with magnesium absorption and re-absorption, significantly interacted with the calcium and magnesium ratio in relation to the both adenomatous and hyperplastic polyps. Participants who carried at least one 1482Ile allele (G->A)of TRPM7 and who consumed diets with a high calcium/magnesium ratio were at a higher risk of adenoma and hyperplastic polyps than were participants who did not carry the polymorphism. We hypothesize that the reduction in the dietary Ca/Mg ratio may change the markers directly related to tumorigenesis. The primary aims of this study are to conduct a randomized placebo-controlled intervention trial to test whether reducing the Ca/mg intake ratio through magnesium supplementation has effects on the related biomarkers. We will also examine whether the effect of modulating Ca/Mg intake ratio may be more pronounced among those who carry the 1482Ile allele compared those who don't carry the 1482Ile allele. Results from our study will help to identify people at a high risk of colorectal adenoma and to develop personalized strategies to prevent occurrence of colorectal adenoma, and thus, colorectal cancer through dietary change or nutritional fortification.

The endocannabinoid system plays important roles in the modulation of gastrointestinal motility and secretions. These effects are mainly mediated by the activation by the endocannabinoids anandamide (AEA) and 2-arachidonylglycerol (2-AG) of CB1 receptors expressed on cholinergic neurons. Cannabis sativa extracts also perform these activities, through the detection of CB1 receptors by the phytocannabinoids they contain, in particular delta9-tetrahydrocannabinol. CB1 receptors are abundantly expressed at the synaptic terminals of excitatory motor neurons and cholinergic secretomotor neurons and their activation induces prejunctional inhibition of acetylcholine release. It is thought that the endocannabinoids AEA and 2-AG, by activating these receptors, may exert a physiological control on gastrointestinal contractility and secretions. This research hypothesizes that drugs capable of inhibiting the biosynthetic and catabolic enzymes of endocannabinoids, of inhibiting the transmembrane transport of endocannabinoids or of allosterically modulating CB1 receptors induce important regulating effects of basal contractility and excitatory motor responses, induced by activation of neurons intramural cholinergics, of colonic circular smooth muscle. The effects of drugs acting on CB receptors, endocannabinoid biosynthetic and catabolic enzymes and endocannabinoid membrane transporters on basal contractility or induced by neuronal activation of colonic preparations in vitro will be evaluated. The study will enroll patients affected by colorectal cancer to undergo elective resective surgery at any stage, undergoing upfront surgery or after neo-adjuvant therapy with a therapeutic interval greater than 6 weeks. In the selected patients (see inclusion/exclusion criteria), a fresh sample of about 2.5 cm of healthy colon (healthy resection margin) will be taken, which will be taken in the operating room and sent to the laboratory for in vitro study. Expected results: The study is expected to provide new evidence regarding the induction of pharmacological effects by allosteric receptor modulators of CB1 receptors, inhibitors of endocannabinoid biosynthetic and catabolic enzymes, and inhibitors of cannabinoid transporters in the human colon, which may open interesting perspectives regarding the development of new therapeutic strategies for the treatment of constipation, diarrhea and irritable bowel syndrome.

The goal of this prospective observational study is to learn about the treatment decisions in advanced colorectal cancer treated with oxaliplatin and irinotecan. The main questions:1. learn about the efficacy and safety of immunotherapy or targeted drugs or other chemotherapy for patients treated with oxaliplatin and irinotecan（non-retreatment/rechallenge group，NR group）. 2. learn about the efficacy and safety of oxaliplatin or irinotecan for patients treated with oxaliplatin and irinotecan (retreatment/rechallenge group, RT/RC group). 3. compare the efficacy and safety of various treatment regimens for patients treated with oxaliplatin and irinotecan. This study will only collect the clinical data of patients, without any intervention, in the treatment services. All participants will be provided written informed consent as per the Declaration of Helsinki principles.

Worldwide, there are 1,361,000 new cases of colorectal cancers (CRC) annually, with 694,000 deaths. However, the incidence varies by up to a factor of 10x between high and low incidence countries (eg. USA vs Mexico, incidence rate of 42.54 vs 7.44 / 100,000 inhabitants). Mexico is considered a low-incidence country, with 8,651 new cases and 4,694 deaths annually. CRC is a preventable and detectable disease. Screening programs established in high-incidence countries have managed to reduce the incidence and mortality from this disease and it is considered a cost-effective strategy. In less developed countries where there are no screening programs for CRC, the highest number of deaths occurs despite having the lowest number of cases. It is recognized that a barrier to establishing a screening program in a country with low incidence and limited resources is cost-effectiveness. The prevalence of Advanced Colorectal Neoplasia (ACN) detected by screening colonoscopy in a Mexican cohort of 1172 INNSZ patients was 2.9%. In the US the prevalence is 7.6%. The number of colonoscopies to be performed to detect ACN was estimated at 34 for Mexico and 13 for the US, which suggests that the cost-effectiveness of screening colonoscopy could be 3 times lower in our country. In Mexico there is no national screening program for CRC. The eligible population (adults between 50 and 75 years old) for CRC screening is estimated in 20 million of Mexicans. It is recognized that Mexico does not have enough financial resources nor the infrastructure to screen the entire eligible population either by direct colonoscopy, or by FIT (fecal immunochemical test) followed by colonoscopy. With a 5% frequency of positive FIT, nearly 1,000,000 follow-up colonoscopies would be required annually in a population screening program. An alternative could be to offer screening based on risk, which means only offering screening to the highest-risk population. There are calculators to predict the risk of identifying ACN in a screening colonoscopy, however, none have been developed and validated in the Mexican population. The weight of the risk factors associated with ACN in the Mexican population could be different, so it is necessary to develop and validate an ACN risk calculator that allows the Mexican population to be stratified and to concentrate screening efforts on the population at highest risk.

This clinical trial tests whether daily fiber supplementation will change the mucosal microbiome of the colon. The microbiome are microorganisms that live in the human gut. They serve a vital role in maintaining health. Certain microbial strains are associated with the growth of colon polyps, which eventually could go on to form colon cancer. Giving dietary fiber supplements may help prevent precancerous polyps from ever developing.

PainPac is innovative in its potential to integrate with healthcare systems through electronic medical records (EMRs). PainPac leverages technology to increase patient access to interventions and uses real-time assessment to improve care. PainPac is positioned to rapidly provide improved care through combining biological data (e.g., EMRs, patient collected) with behavioral data to dramatically improve outcomes. PainPac could track beneficial outcomes related to clinical pain scores (e.g., patients with scores 4-8 benefit) and intervention implementation could be based on this; a more advanced possibility is use of geospatial tracking to predict space/time where pain is likely to impact functioning and push an intervention strategy - behavioral or pharmacological. PainPac is designed for future transmission of data to EMRs to inform providers of patient status. This work will provide data to bypass traditional efficacy trials and move quickly to a large effectiveness trial.

Colorectal cancer (CRC) is a common cancer that threatens human health, with the incidence ranking the third in the world. 70% of patients are in the middle and late stages whendiagnosed, and even after radical surgery, 30% - 50% of patients with CRC have recurrence or metastasis after radical surgery. Therefore, after radical surgery and adjuvant chemotherapy, regular monitoring of CRC patients should be paid attention to in order to detect the recurrence and metastasis lesions that can be resected and the early non-invasive metachronous multiple primary tumors. The sensitivity of FIT-DNA to CRC was 95.5%, the sensitivity to advanced adenoma (AA) was 63.5%, and the specificity was 87.5%, showing a good ability to screen colorectal cancer and precancerous lesions. At present, there is no report on the application of FIT-DNA combined detection technology in the high-risk recurrence period and mid - and long-term monitoring after CRC surgery in China. In this study, Fit-DNA combined detection technology was applied to the follow-up monitoring of patients after CRC surgery, so as to optimize the current typical postoperative follow-up strategy, find early recurrence and multiple primary colorectal tumors after CRC surgery, seek the best postoperative follow-up model, improve the compliance of patients to follow-up, and ultimately benefit survival. Detailed Description:Outline:This study was a single-center, observational study. Fit-DNA detection technology was used as a target method, and colonoscopy was used as the gold standard control to follow up and monitor patients with colorectal tumors after surgery, and to explore whether it is an effective non-invasive auxiliary method for monitoring CRC recurrence and metastasis and multiple primary colorectal tumors.
