Filter by:This trial was designed to to study whether there is a difference in MRI image evaluation between NCRT and NCT, and try to build a model to predict the efficacy of neoadjuvant therapy by combining multiple imaging indexes.
This study is designed to test the efficacy and safety of Total Neoadjuvant Treatment plus SHR1210（an anti-PD-1 Inhibitor) for High-risk locally advanced Rectal Cancer, Meanwhile, screening effective Biomarker base on neoantigen.
The purpose of this pilot study is to a) explore the photoacoustic properties of normal, polypoid, and malignant colorectal tissue and b) demonstrate the functionality of a novel endorectal photoacoustic ultrasound probe in humans with rectal cancer. The study includes two parts. The initial exploratory portion will be conducted ex vivo with resected colon and rectal specimens immediately following surgical excision. Based on those findings, an endorectal probe will then be constructed to examine in vivo tumors. The investigators hypothesize that in vivo photoacoustic imaging will be capable of differentiating normal from malignant tissue.
Within our institution, the principal investigator have acquired expertise in endorectal brachytherapy, a localized treatment for colorectal cancer. Until now a modality which uses an endorectal applicator has been used, which has certain limitations. In the context of this study, a new applicator will be used which is already approved by Health Canada for endorectal brachytherapy, thereby improving the participant's quality of life and optimizing treatment time.
This trial is assessing how Bladder filling variations and thus mesorectal movements are less when radiotherapy treatment is received with an empty bladder in rectal cancer
VAPOR-C is a randomised study of the impact of IV versus inhaled anaesthesia (propofol versus sevoflurane) and lidocaine versus no lidocaine on duration of disease free survival inpatients with either colorectal or non small cell lung cancer.
This study is designed to test the Safety and efficacy of induction and individualized neoadjuvant chemotherapy based on oxaliplatin combined with fluorouracil for MRF-negative, moderate-risk and initially resectable middle and low rectal cancer.
The addition of durvalumab to total neoadjuvant therapy (TNT) in locally advanced rectal cancer may improve the pathological complete response rate. The induction platinum-based chemotherapy may increase the neoantigen formation together with the chemoradiotherapy period. Starting durvalumab during the first chemotherapy session and continuing during the 6-week period of chemoradiotherapy could change and create the needed environment to increase the efficacy of durvalumab in this setting. Additionally, the 8-12 week rest period from the end of the chemoradiotherapy and the radical surgery, treatment with durvalumab may continue improving the response and outcome of patients without jeopardizing the surgery (which needs this period out of chemotherapy and radiotherapy to avoid postoperative complications, but not for anti-PDL-1 therapy). Patients will be included following inclusion/exclusion criteria in a prospective, non-randomized, open label, single arm phase II study to receive 6 cycles of mFOLFOX6 (oxaliplatin, leucovorin and fluorouracil) followed by long course chemoradiotherapy (50.4 Gy together with capecitabine) followed by surgery. Patients will receive durvalumab 1500 mg every 4 weeks during induction chemotherapy, chemoradiotherapy and waiting period until surgery.
In patients with advanced rectal cancer, molecular subtypes will be identified by preoperative biopsy, CT, MRI / PET radiomics analysis, clinical features, and clinical features will be confirmed and compared. Also, we want to confirm the relationship between these factors and the treatment response after chemoradiotherapy before surgery. The prognosis will be then assessed through 5-year overall survival and 3-year disease free survival. A prospective clinical trial, recruiting 210 persons (approximately 53 per year) that meet the selection criteria for approximately four years from the IRB approval date in 2019 (about 53 per year) We will analyze the data and then collect and analyze the data and report the results.
In this study, investigators seek for a better way to identify the potential pathologic complete response (pCR) patients form non-pCR patients with locally advanced rectal cancer (LARC), based on their post-neoadjuvant treatment Magnetic Resonance Imaging (MRI) data. Previously, a post neoadjuvant treatment MRI based radiomics AI model had been constructed and trained. Here, the predictive power of this artificial intelligence system and expert radiologist to identify pCR patients from non-pCR LARC patients will be compared in this prospective, multicenter, back-to-back clinical study
