Filter by:Data from a prior phase II study of single agent cabozantinib in metastatic, refractory colorectal cancer (NCT03542877) combined with the compelling preclinical data in colorectal mouse models utilizing cabozantinib combined with nivolumab have led to this concept for a clinical trial to combine cabozantinib and nivolumab in patients with metastatic MSS CRC in the third line setting and beyond.
This is a retrospective study comparing neoadjuvent short course radiotherapy to conventional chemoradiation in locally advanced cancer rectum and the effect of both regimens in overall survival and disease free survival
This study is a prospective, open-label, phase I design.
This phase I trial investigates how well short-course radiation therapy followed by combination chemotherapy works in treating patients with stage II-III rectal cancer. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as leucovorin, fluorouracil, oxaliplatin, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving short-course radiation therapy and combination chemotherapy may reduce the need for surgery and therefore improve quality of life.
PRIME-RT is an open label, multi-centre phase II randomised trial with 1:1 allocation between arm A and arm B. The principal research question is whether the addition of durvalumab to FOLFOX chemotherapy and radiation treatment (either SCRT or LCRT) in the neoadjuvant setting for patients with locally advanced rectal cancer (LARC) improves rates of complete response. The working hypothesis is that the use of radiation and cytotoxic chemotherapy may prime the tumour immune microenvironment for treatment with immune checkpoint blockade. The main trial will commence after completion of a safety run-in which will enrol at least three patients per arm to test the safety and tolerability of the treatment combinations in each.
Even if colonoscopy is considered the reference standard for the detection of colonic neoplasia, polyps are still missed. The risk of early post-colonoscopy cancer appeared to be independently predicted by a relatively low polyp/adenoma detection rate. When considering the very high prevalence of advanced neoplasia in the FIT-positive enriched population, the risk of post-colonoscopy interval cancer due to a suboptimal quality of colonoscopy may be substantial. Available evidence justifies therefore the implementation of efforts aimed at improving adenoma detection rate, based on retraining interventions and on the adoption of innovative technologies, designed to enhance the accuracy of the endoscopic examination. Artificial intelligence seems to improve the quality of medical diagnosis and treatment. In the field of gastrointestinal endoscopy, two potential roles of AI in colonoscopy have been examined so far: automated polyp detection (CADe) and automated polyp histology characterization (CADx). CADe can minimize the probability of missing a polyp during colonoscopy, thereby improving the adenoma detection rate (ADR) and potentially decreasing the incidence of interval cancer. GI Genius is the AI software that will be used in the present trial and is intended to be used as an adjunct to colonic endoscopy procedures to help endoscopists to detect in real time mucosal lesions (such as polyps and adenomas, including those with flat (non-polypoid) morphology) during standard screening and surveillance endoscopic mucosal evaluations. It is not intended to replace histopathological sampling as a means of diagnosis. The objective of this study was to compare the diagnostic yield obtained by using CADe colonoscopy to the yield obtained by the standard colonoscopy (SC).
This study is a prospective, single-arm, single-center study of investigator's choice of total neoadjuvant therapy (TNT) or neoadjuvant chemoradiation in locally advanced rectal cancer. The standard of care for rectal adenocarcinomas that are triiodothyronine-thyroxine (T3-T4) or node positive has generally been comprised of neoadjuvant chemoradiation, followed by surgical resection and then adjuvant chemotherapy. More recently, TNT, comprised of neoadjuvant chemotherapy and chemoradiation followed by surgical resection, has been increasingly used as a standard therapy approach. While the use of TNT is increasingly common, prospective study of outcomes following TNT has been limited. Moreover, there are not any biomarkers known at this time that impact clinical decision-making or personalization of therapy in the treatment of rectal cancer. In this study, we will collect pre-treatment rectal adenocarcinoma specimens and determine clinical outcome, including pathologic complete response rate, post-treatment pathologic downstaging rate, recurrence-free survival (RFS), overall survival (OS) and neoadjuvant rectal score, among patients who are treated with standard neoadjuvant chemoradiation or TNT, with an aim to investigate how baseline biomarkers and changes in biomarkers with standard therapies may be associated with, and modulate, clinical outcomes.
This phase I trial studies the side effects and best dose of ropidoxuridine and how well it works when added to the usual chemotherapy treatment (capecitabine) during radiation therapy for the treatment of patients with stage II-III rectal cancer. Ropidoxuridine may help radiation therapy work better by making cancer cells more sensitive to the radiation therapy. Chemotherapy drugs, such as capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. This study is being done to find out whether ropidoxuridine in addition to capecitabine and radiation therapy works better in treating patients with rectal cancer.
The aim of this project is to audit the surgical care in patients treated for colorectal adenocarcinoma. This study focused on collecting data from all consecutive cases of colon and rectal adenocarcinoma operated at the National Institute of Oncology in Rabat during a two-years period. Using standardized forms, the investigators collected data relating to each stage of treatment: pre-therapeutic, surgical and post-operative in order to measure the quality of the surgical care delivered. These results were compared to established benchmarks and to similar audit studies carried out in other countries around the world.
