Filter by:This is an observational study with the goal to improve the robustness of the scientific evidence linking Fusobacterium nucleatum (Fn) and/or other microorganisms to colorectal cancer (CRC) onset and/or progression. This is an approximately three-year study. There are two phases to this study, including: 1) pilot phase, 2) full study. There are also five arms in this study including cancer-free, pre-cancerous, and Colorectal cancer stages (I-III). The pilot study will include the recruitment of 50 participants per group (i.e., total of 250 participants). The full study will have an additional 150 participants per group (total of 1,000 participants). This study will recruit using clinical sites in the United States. There are 5 timepoints in this study. If the participants are found to be medically eligible through diagnosis and medical information, they will provide samples (including: saliva, blood, urine, stool and tumor biopsy) at each timepoint and during the study. They will also answer health and wellness questions during this study. Additional data collection, including medical data, biopsies and other biological samples might happen at interim timepoints in case of adenoma/cancer disease progression (recurrence, metastasis). The participant's healthcare provider will determine if additional biopsies are required as a part of the standard of care. If collected, additional samples will be sent for research purposes.
This study will assess the safety, efficacy, and pharmacokinetics of THE-630 in participants with advanced gastrointestinal stromal tumors (GIST).
This study will evaluate the efficacy and safety of alectinib in participants with Anaplastic Lymphoma Kinase (ALK)-positive locally advanced or metastatic solid tumors other than lung cancer.
A phase 1, open-label, dose escalation and expansion study of PF-07062119 in patients with selected advanced or metastatic gastrointestinal tumors
The purpose of the study is to determine whether standardized implementation of a scripted template for discussing important issues that arise near the end of life improves the care of those who have advanced cancer.
This study will include two parts: - In the phase I part: safety will be assessed in consecutive cohorts of 3 to 6 patients at increasing doses of TG6002 in combination with oral flucytosine (5-FC) in patients with advanced gastro-intestinal (GI) tumors. - In the phase IIa part: evaluation of efficacy and further evaluation of safety of multiple administrations of TG6002 in combination with flucytosine (5-FC) in patients with colorectal cancer and liver metastases. In both parts, tumor response will be evaluated on local assessment using RECIST 1.1. All patients will be followed up until disease progression or death due to any cause or the date of data cut-off, whichever occurs first.
Surgery for digestive cancers is managed according to quality standards, validated by the scientific community. Despite the diffusion of these standards through the benchmarks of good practice, the results of the surgery remain disparate. In many countries, this "inequality of opportunity" has justified the establishment of quality assurance systems to measure the results of surgery for one or more localizations of digestive cancer. These surgical audit experiments have shown a positive, rapid and cost-effective impact on complication rates, recurrence rates and overall survival even in the absence of interventional measures. The data collected also helped to improve the management of subgroups of patients usually excluded from clinical trials. In Morocco, the National Cancer Prevention and Control Plan provides for the establishment of a quality assurance system with the introduction of a system for monitoring and evaluating the care of patients. This pilot project is part of this framework, for the group of patients who are candidates for surgery for digestive cancers.
This study will evaluate the safety and efficacy of mebendazole (ReposMBZ) in patient with advanced gastrointestinal cancer or cancer of unknown origin. All patients will be given ReposMBZ for 16 weeks continuous treatment, individually dosed based on the serum concentration of mebendazole.
This is an open-label, stratified, two arm design. All patients receive same initial standard preoperative chemotherapy and surgical resection. Patients will then be assigned to either standard postoperative chemotherapy if node negative at surgery or standard postoperative chemoradiation if node positive at surgery. The primary objective of this study is to determine the feasibility of patients enrolling and receiving either postoperative chemoradiation or chemotherapy alone, based upon nodal status at surgery, following preoperative chemotherapy. The secondary Objectives is to evaluate the rate of cancer recurrence in patients assigned to treatment based upon node status. To explore the potential correlation between changes in expression of a pre-specified panel of genes identified as relevant to gastrointestinal cancers in response to preoperative chemotherapy, using presence of nodal involvement at time of surgery as an indicator of response.
Background: Exome sequencing can identify certain gene mutations in a person's tumor. This can then be used to create cancer treatments. In this study, researchers will make a treatment called a messenger ribonucleic acid (mRNA) vaccine. The vaccine might cause certain tumors to shrink. Objective: To see if the mRNA vaccine is safe and can cause metastatic melanoma or epithelial tumors to shrink. Eligibility: People 18-70 years old with metastatic melanoma or epithelial cancer Design: Participants will be screened under protocol 99-C-0128. Participants will provide samples under protocol 03-C-0277: Participants will provide a piece of their tumor from a previous surgery or biopsy. Participants will have leukapheresis: Blood is removed through a needle in one arm and circulated through a machine that takes out the white blood cells. The blood is then returned through a needle in the other arm. Participants will have many tests: Scans and x-rays Heart and lung function tests Blood and urine tests Participants will receive the mRNA vaccine every 2 weeks for up to 8 weeks. They will get the vaccine as an injection into the upper arm or thigh. They may receive a second course of vaccines if the study doctor determines it is needed. Participants will have follow-up visits approximately 2 weeks after their final vaccine, then 1 month later, then every 1-2 months for the first year, and then once a year for up to 5 years. Each visit may take up to 2 days and include: Physical exam Blood tests Scans Leukapheresis at the first visit
