Filter by: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.
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.
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.
Colorectal cancer is the third most common cancer in the UK and Ireland, it is the second commonest cancer in both men and women. Very often the diagnosis is made by either endoscopy/colonoscopy and the surgical treatment is carried out by a minimally invasive approach ("Keyhole"surgery). Tissue samples gathered by either approach are sent to the pathologist to confirm the nature of their content. At present this takes some time (days) and so the information cannot guide the procedure being done or indeed any other investigations or processes that need implementation as soon as possible until the pathology process is completed. Fluorescence guided surgery uses an approved dye along with approved cameras to add more information regarding tissue characteristics then is available by normal viewing alone. It has already been shown to be associated with an improvement in safety related to healing after colorectal surgery and the investigators are sooning in a randomised trial examining this in rectal cancer to prove it. Whether or not this trial proves this or not, the ability to better understand tissue health during investigation/operation needs further examination and development. In this study, the investigators will examine the role of computer vision and machine learning in determining the nature of the tissue being seen in real-time additive to the surgeons' own opinion and experience. This is needed because the dynamic phases of fluorescence inflow into any tissue is difficult to interpret most especially when it relates to microvasculature as is present within a cancer site or deposit. By this means the investigators hope to better understand the dynamic perfusion in and out of tissue whether normal or abnormal and define signatures that can speed up and/or help inform the surgeon regarding the actual nature of the tissue being seen. The investigators will compare the data being generated with that already being captured with regard to standard pathology and radiology and other laboratory measures of clinical course. Tissue resected from a patient will also be examined in the laboratory under near-infrared microscopy and analysed for fluorescence intensity to understand where exactly and how much of the dye accumulates in specific regions of tissue. There are no new operations in this study and no new interventions are being made on the basis of the information being gathered- it's a comparative study to see how this added information can add value to interventionalists during surgery. There are four collaborating groups involved in this research consortium, two are commercial partners as they add value in both this advanced field of analytics and in the ensuring a clinical business case is included so that findings of this work can be useful for patients.
Volatile organic compounds (VOCs) are low molecular weight (<1 kDa) compounds which represent the final products of cell metabolism. Their composition can be affected by several factors including diet, hormones, environment and the presence of diseases, in particular, cancer. Colorectal cancer (CRC) is one of the commonest tumours and is an important cause of cancer-related mortality. The expression of VOCs in breath that are linked to a patient's disease state could offers a powerful, non-invasive approach to identifying CRC patients.
Prospective registry study of endoscopic submucosal injection of indocyanine green before laparoscopic radical resection for colorectal cancer
This study uses the opinions of adults between the ages of 45 and 73 years old to develop and test an interactive nutrition module for use in an existing colorectal cancer screening intervention using virtual human technology. This study will contribute to knowledge of what messages and graphics promote understanding of cancer risk and promote screening.
A single-center prospective study to elucidate whether extended robot-assisted right colectomy (e-RARC) performs as well as extended open right colectomy (e-ORC) in terms of specimen quality, and in addition, whether less postoperative morbidity and shorter length of stay (LOS) can be attained. Patients with colonic cancer near the right flexure or the oral part of the transverse colon will be compared excluding the most technically demanding and frail patients in both groups. A total of 40 patients undergoing e-RARC in a prospective series will be included and compared with 44 consecutive patients previously treated with e-ORC.
This is a cross-sectional study aimed at identifying factors which best predicts patients at high risk of colorectal cancer or colorectal adenomas and to develop a risk prediction model.
Digestive cancers (liver, colonic, pancreatic) have a high incidence and high mortality, their population prevalence is also increasing. Given that the anesthesia techniques and the agents used act directly and indirectly on the immune system during the perioperative period, influencing both the treatment and the prognosis of patients with colorectal cancer who undergo elective interventions, a series of perianesthetic interventions have been proposed in order to reduce morbidity-mortality perioperative.
