View clinical trials related to Colorectal Tumors.
Filter by:Colorectal cancer (CRC) is one of the most common malignant tumors in the world. Surgical resection is the main treatment option for colorectal cancer patients. Surgery may enhance or accelerate tumor recurrence and metastasis. Multiple factors in the tumor microenvironment play important roles in tumor recurrence and metastasis, and modulating the tumor microenvironment can inhibit disease progression. Lidocaine has been found to inhibit tumor growth in animal experiments.
This is Phase Ib/II, multicenter, open-label adaptive platform study of JDQ443 with select therapies in patients with advanced solid tumors harboring the KRAS G12C mutation.
This proposed study is designed to investigate the specific uptake of fructose by human colorectal tumors. In this study, subjects with colorectal cancer undergoing surgery will receive an oral sugar solution containing fructose or xylose prior to surgery. The tumor will then be resected, and a portion of the tissue will be used to measure the abundance of fructose and xylose. The study hypothesis is that the tumors will take up fructose sugar but not xylose sugar. A comparison of the sugar uptake between the tumor and normal tissues from the adjacent intestinal epithelium and smooth muscle and the liver will be conducted. This proposal will confirm that human colorectal cancer tumors can directly absorb dietary sugars, which has never been demonstrated.
Background: Gastrointestinal cancer is one of the most common cancers worldwide. Researchers think an unmet need exists to understand and improve treatment options. They want to see if a combination of drugs can help people with metastatic colorectal cancer. Objective: To see if using a combination of Vascular Biogenics (VB)-111 and nivolumab is safe and will cause colorectal tumors to shrink. Eligibility: People ages 18 and older with microsatellite stable colorectal cancer that has spread to the liver Design: Participants must consent to sample collection protocol 11C0112. Participants will be screened with: Blood tests Scans Tumor samples. If these are not available, participants will have a biopsy. Before they start treatment and with every treatment cycle, participants will have: Physical exams Blood tests Heart tests Before they start treatment and every 4 cycles, participants will have computed tomography (CT) or magnetic resonance imaging (MRI) scans. For these, they will lie in a machine that takes pictures of the body. For the MRI, a soft padding or coil will be placed around their head. Participants will have biopsies before they start therapy. They will have them again after 2 6 weeks on study. On day 1 of 14-day cycles, participants will get one or both study drugs by vein. After they finish treatment, participants will have monthly visits for 3 months. They will have a physical exam and blood tests. If participants stop treatment for reasons other than their disease getting worse, they will have scans about every 8 weeks. This will continue until their disease gets worse. Participants will be contacted by phone or email every 6 months. This will continue for life. ...
This is a three-part study of NUC-3373 administered by intravenous (IV) infusion across two administration schedules, either as monotherapy or as part of various combinations with agents commonly used to treat CRC (leucovorin, oxaliplatin, irinotecan, bevacizumab, cetuximab and panitumumab). The primary objective is to identify a recommended dose and schedule for NUC-3373 when combined with these agents.
The purpose of this study is to investigate treatment with nivolumab in combination with trametinib with or without ipilimumab in participants with previously treated cancer of the colon or rectum that has spread.
Background: Colorectal cancer is a common cancer in the Unites States (U.S.) It causes the second most cancer-related deaths. The drug avelumab and vaccine Ad-CEA together help the immune system fight cancer. Objective: To test if avelumab and Ad-CEA plus standard therapy treats colorectal cancer that has spread to other sites better than standard therapy alone. Eligibility: People ages 18 and older with untreated colorectal cancer that has spread in the body Design: Participants will be screened with: Test to see if their cancer has a certain deficiency Blood, urine, and heart tests Scans Medical history Physical exam Tumor sample. This can be from a previous procedure. A small group of participants will get Ad-CEA and avelumab plus standard therapy. This is leucovorin calcium (folinic acid), fluorouracil, and oxaliplatin (FOLFOX) plus bevacizumab for up to 24 weeks then capecitabine plus bevacizumab. The others will have treatment in 2-week cycles. They will be Arm A or B: Arm A: FOLFOX and bevacizumab by intravenous (IV) days 1 and 2 for 12 cycles. After that, capecitabine by mouth twice a day and bevacizumab by IV on day 1. Arm B: Ad-CEA injection every 2-12 weeks. Avelumab by IV on day 1 of each cycle. FOLFOX and bevacizumab by IV days 2 and 3 for 12 cycles. Then, capecitabine by mouth twice a day and bevacizumab through IV on day 2. Participants will repeat screening tests during the study. Participants will be treated until their disease gets worse or they have bad side effects. Arm A participants can join Arm B. They will have a visit 4 5 weeks after they stop therapy.
Antibiotic lavage reduces bacterial contamination and decreases SSI infection rate. SSI leads to an immunocompromised situation, leaving unattended the neoplasm. It has been described that SSI may result in a worse oncologic outcome.
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
The incidence of colorectal cancer (CRC) is on the rise on a global scale. The number of cancer-related deaths related to CRC is also rising to an alarming level. This picture is similarly seen in Egypt where the incidence of colorectal carcinoma is increasing annually, moreover, CRC in Egypt exhibits an alarming characteristic which is the affection of much younger patients than their counterparts worldwide. Fortunately, the early detection of CRC and its precursor (adenoma) has been shown to markedly decrease morbidity and mortality related to this tumor, this has prompted the development of robust screening programs for CRC in several western countries. The implementation of a CRC screening program in Egypt has been hampered by the low compliance of the patients and the relatively high cost of colonoscopy. There is a need for an affordable, non-invasive, simple, accurate and socially accepted screening test to allow such a program to succeed in Egypt. Recent studies have shown that DNA is the future target of screening tests for several malignancies. Particularly for CRC a few preliminary studies have shown encouraging results with separate DNA methylation markers both in blood and stool. In our efforts to develop a screening test with the criteria stated above, the investigators have decided to join the forces of 2 of the largest medical centers in Egypt and the middle-east: Kasr-Alaini hospital and the National cancer institute (NCI). The investigators plan to test a panel of 7 DNA methylation markers in peripheral blood for their performance as an early marker for CRC and colorectal adenomas. Data from this study will pave the way for the development of a screening test for CRC "tailored" to the Egyptian population, moreover, it will supply essential data about the genetic alterations occurring in CRC in Egyptian patients.
