Filter by:The hypothesize of this research is that rapamycin is effective and well-tolerated in teenagers with familial adenomatous polyposis (FAP). Rapamycin could be effective in blocking the formation of adenomas and/or their evolution by decreasing their size and number. Researchers aim to assess the safety profile of rapamycin in FAP adolescents using a 2 low dose regimen.
To compare the differences of clinical pathological, treatment and prognosis in the guided subgroups in colorectal cancer, the investigator enrolled all the colorectal cancer patients who underwent surgery and were hospitalized in the Xijing hospital.
CoLiQ is an observational study designed to evaluate the clinical usefulness of circulating tumor DNA (ctDNA) markers found in blood, as a liquid biopsy for diagnosis, prognosis and follow-up of colorectal cancer. The main questions it aims to answer are: 1) Can a panel of ctDNA markers identify CRC patients among the other patients summoned for colonoscopy? and 2) Does the type, number and level of ctDNA markers vary with the subtype and clinical course of CRC? Participants will be asked to answer a questionnaire and give a blood sample at inclusion. In addition, patients with CRC will be asked to give an extra test tube at their routine treatment and follow-up blood sampling.
This phase I/II trial studies the side effects and how well fluorescence image guided surgery followed by intraoperative photodynamic therapy for improving local tumor control in patients with colorectal cancer that has spread to nearby tissue or lymph nodes (locally advanced) or that has come back after a period of improvement (recurrent). Fluorescence image guided surgery uses a drug named aminolevulinic acid hydrochloride. Aminolevulinic acid hydrochloride is a photosensitizing agent, meaning that is activated by light and, is converted to another drug in cancer cells more than in normal cells. The converted drug emits fluorescence red light when activated with low power blue light. It is used to assist the surgeon to see cancer cells and small cancerous tissue that may have been missed during routine surgery. In addition to emitting fluorescence light, the converted drug in the cancer cells and tissue can be activated with red laser light to kill cancer cells. This procedure is called photodynamic therapy (PDT). Performing fluorescence image guided surgery followed by intraoperative photodynamic therapy after the surgical removal of the colorectal tumor before the surgical site will be closed may be effective and improve outcomes in patients with locally advanced or recurrent colorectal cancer.
This is a prospective, multicenter, single-arm clinical investigation designed to evaluate the accuracy of the Gixam™ System in identifying subjects with colorectal adenomas compared to optical colonoscopy. Subjects arriving for a standard of care colonoscopy at the investigation site will be offered to participate in the study. Following an informed consent process, images of the subjects' tongue will be obtained with the Gixam™ System and a prediction score will be generated by the Gixam™ AI model. Subjects will thereafter proceed to their SOC colonoscopy, and the Gixam™ score will be compare with colonoscopy findings to evaluate its performance.
The unplanned readmission rate after colorectal cancer surgery is still high, despite the implementation of enhanced recovery programs. The use of a mobile-based application for perioperative remote monitoring may improve the postoperative outcomes and reduce the unplanned postoperative readmissions.
Aim of our study is to find frequency and identify risk factors for venous thromboembolism development in patients who underwent surgery for colorectal cancer. There were 137 patients enrolled in our retrospective observational cohort study. Included patients were operated for incisional hernia in Saveljev University Surgery Clinic from January 2016 to December 2017. Compression duplex ultrasound of lower legs veins was performed in 2-14 days after surgery for all participants. The primary endpoint was the occurrence of the venous thromboembolism event, including pulmonary embolism.
The goal of this clinical trial is to learn about efficacy of Everolimus in combination with PD-1 in patients with locally advanced and advanced colorectal cancer that cannot be R0 resected. The main question is to explore the survival time, safety and tolerability of the treatment. At the same time, the correlation between biomarkers (including PD-L1 expression, tumor mutation load, lymphocyte subpopulation, cytokines, TCR, intestinal microbes, and others) and the efficacy and drug resistance mechanism will be analyzed, so as to provide reference for the subsequent guidance of the screening of benefit groups.
The goal of this clinical trial is to to learn about different combinations of immunotherapy in patients with colorectal cancer whose cancer has spread to their liver and are planning to have surgery to remove tumor metastases from their liver. The main questions it aims to answer are: - whether these combinations of immunotherapy change the tumor microenvironment in the liver - whether these combinations of immunotherapy are safe and effective when used in colorectal cancer with liver metastases Participants will be randomly assigned to one of the following: - Botensilimab and balstilimab - Botensilimab, balstilimab, and AGEN1423 - Botensilimab, balstilimab, and radiation Participants will be asked to come in to receive drug infusions (and radiation, if applicable) before and after their surgical resection. Participants will be followed for up to 2 years.
To evaluate the safety, immune response, and potential efficacy of combined immune cell therapy in patients with stage 4 colorectal cancer who have failed standard treatment and have unresectable lesions or metastatic lesions.
