Filter by:Maintenance treatment can extend patient survival and improve patient quality of life. Bevacizumab alone or capecitabine combined with bevacizumab as a maintenance treatment have been widely used in clinical practice. In contrast, there are little datas of cetuximab as a maintenance treatment. The purpose of this study is to evaluate efficacy and safety of Raltitrexed plus Cetuximab as the maintenance treatment, and to provide a new choice for RAS wild-type colorectal cancer patients after advanced first-line chemotherapy.
Nowadays endoscopic mucosal resection (EMR) is the gold standard for the removal of large laterally spreading and sessile colorectal lesions ≥ 20 mm. However, recurrence rate after successful EMR (defined by the absence of neoplastic tissue at the completion of the procedure after careful inspection of the post-EMR mucosal defect and margin) is about 15-20%. Consequently, current guidelines recommend a surveillance colonoscopy between 4 and 6 months after resection for detection of residual or recurrent polyp. There are few studies that have examined the accuracy of advanced endoscopic imaging for the prediction of histological recurrence but none of these imaging modalities have been validated for surveillance after EMR. Therefore, current guidelines strongly recommend systematic biopsy of EMR scar. The main aim of this study is to assess the incremental benefit of narrow band imaging (NBI) and white light endoscopy (WLE) randomizing the initial technique for the endoscopic detection of post-EMR recurrence and to asses if this advanced imaging method achieve sufficient diagnostic accuracy to exclude recurrence without the need for biopsy.
Over-expression of Epidermal Growth Factor Receptor (EGFR) on cells occurs in all aggressive cancers of epithelial origin. Existing tests for monitoring EGFR expression are invasive and not reliable. There needs to be a better way to measure EGFR expression in cancerous tumors to better tailor cancer treatments. This clinical trial aims to demonstrate the feasibility of imaging cancers that express EGFR using 89Zr-DFO-nimotuzumab and Positron Emission Tomography (PET)/Computerized Tomography (CT). By non-invasively imaging the status of EGFR, 89Zr-DFO-nimotuzumab could be used to assist in the identification of patients who are likely to respond to anti-EGFR treatments, including nimotuzumab. The hypothesis is that 89Zr-DFO-nimotuzumab will accumulate to tumors over-expressing EGFR making them visible when imaged with PET/CT. This hypothesis will be tested in this study, along with the optimal imaging time and diagnostic ability.
MRI is a potentially powerful tool to reliably determine the intra-abdominal tumor load and relations with intra-abdominal organs. In recent years diffusion weighted MRI has proven its value as a highly sensitive technique to detect small malignant disease in a wide variety of cancers [1-3]. However, literature concerning the clinical impact of detecting peritoneal metastases with MRI is very limited. Therefore, there is a need for a large randomized multicenter trial to determine whether dedicated MRI can be used as a selection tool for CRS-HIPEC candidates in daily practice.
The current clinical trials and data on the triplet regimen combined with bevacizumab for first-line treatment of metastatic colorectal cancer were from European and American populations. The triplet regimens recommended by the NCCN and ESMO guidelines using irinotecan and 5-FU at a higher dose intensity cause a high incidence of adverse events in Asian population, and there was no high-quality data on efficacy in Chinese population, both of which have limited the clinical applications of the regimens in China. This study intends to conduct an improved triplet regimen (mFOLFOXIRI) combined with bevacizumab versus mFOLFOX6 combined with bevacizumab as a first-line multicenter, randomized, controlled phase III clinical trial in patients with advanced colorectal cancer. Progression-free survival (PFS), observable response rate (ORR), overall survival (OS), disease control rate (DCR), surgical resection rate, and safety and health-related quality of life (HRQoL) were assessed in the two groups of subjects.
In addition to microbiota-host interaction on inflammatory response, many enzymes, including three enzymes critical in gluconeogenesis and transport of amino acids and carbohydrates in energy metabolism, are dependent on the Ca/Mg ratio, indicating critical roles of the Ca/Mg ratio in carbohydrate fermentation and energy metabolism in bacteria. In pilot metagenomic study conducted by the investigators, they found all the significantly changed biologic functions within the microbial community caused by a reduction in the Ca/Mg ratio are biologically dependent on the Ca/Mg ratio or Mg. It is striking that the functions with significant changes in stool samples were centered on the fermentation of carbohydrates and energy metabolism while the functions in rectal swabs were related to immune response. Tissue also had a distinct profile from stool and swab. These findings have very broad clinical and public health significance for many inflammation-related diseases or metabolic disorders. Due to the small sample size in the pilot study, the investigators plan to confirm these findings using the biospecimens collected in the parent study (Personalized Prevention of Colorectal Cancer Trial, NCT01105169).
The purpose of this study is to evaluate the safety and efficacy of SCT-I10A combined SCT200 or SCT-I10A combined SCT200 plus chemotherapy in advanced esophageal squamous cell carcinoma and colorectal cancer
By analyse the tissue/blood variant spectrum model using NGS, the present clinical trial aims to elucidate the genetic basis of CRC in Chinese; to establish of CRC genetic map in Chinese patients; to identification new genetic biomarkers, drug and pathways; and to subtyping for precision treatment and management for Chinese CRC patients.
Trial Design: This is a feasibility randomised controlled trial. Aim: The study aims to test the Healthy Eating and Active Lifestyle After Bowel Cancer - HEAL ABC intervention and HEAL ABC resources for feasibility and will inform a future definitive randomised controlled trial (RCT). Objectives: 1. Is it practical to run HEAL ABC study as a definitive randomised controlled trial? 2. Adherence to intervention, motivations, barriers and facilitators of CRC survivors to follow HEAL ABC. Study Population: Colorectal cancer survivors who completed surgery and/or active treatment. Intervention: The intervention group will use HEAL ABC resource with supportive telephone calls every two weeks during the intervention period and once a month during the follow up period. Control: Participants follow standard care recommendations. Timing and duration: 3 months intervention with 6 months follow up period
The primary objective is to compare the performance of Stool-based SDC2 DNA Methylation Test and commercially available Fecal Immunochemical Test(FIT) , on the detection rate of advanced adenomatous polyps and colorectal cancer in Chinese population. Subjects with positive results in either test will receive colonoscopy. Lesions will be confirmed as malignant or precancerous by colonoscopy and histopathologic examination.
