Filter by:Patients with colorectal cancer will be recruited to undergo vitamin D supplementation in the peri-operative period. Vitamin D levels (25OHD) will be measured to assess response to supplementation.
The overall goal of this educational program was to increase colorectal cancer screening (CRCS) in men and women who attend Federally Qualified Health Centers (FQHC) in Puerto Rico. FQHCs, referred to in Puerto Rico as "Clínicas 330", are ideal settings to implement innovative approaches to increase CRCS because they serve primarily low-income patients who typically have lower rates of screening. The goal of this study, is to develop and evaluate the impact of a clinic level intervention on increasing CRCS among low-income Puerto Rican men and women aged 50-75, who have either never been screened for colorectal cancer, or are under-screened according recommended guidelines. To evaluate the delivery of the CRCS education program we used a group randomized controlled trial that provided data to determine the effectiveness of the CRC intervention program compared with usual practice (no intervention).
A cardiopulmonary exercise test (CPET) is increasingly used for preoperative risk assessment. Oxygen uptake (VO2) at peak exercise (VO2peak) and VO2 at the ventilatory anaerobic threshold (VO2VAT) are the most commonly used preoperative CPET variables that are associated with postoperative outcomes following colorectal cancer surgery. The aim of this study is to investigate the association between two relatively new preoperative submaximal and effort-independent CPET variables, the cardiopulmonary optimal point (COP) and the Oxyen uptake efficiency plateau (OUEP) and postoperative outcomes in colorectal cancer surgery. In additiion, the association between the oxygen uptake at the COP en OUEP and postoperative outcomes wil be explored.
The study involves the planned use of a new microwave-based device during colonoscopy procedures in a small group of patients to assess the preliminary safety of its use and lack of normal clinical practice modification. The device is a final design version, which has been previously tested in several preclinical studies, including: phantom studies, an ex vivo study with human tissues, and an in vivo study with animal model (pig).
For patients with initially unresectable colorectal liver metastasis (IU-CRLM) receiving effective conversion therapy, disease relapse after conversion hepatectomy is common due to the extensive tumor load. Yet, few studies have focused on the assessment and management of relapse after conversion hepatectomy for IU-CRLM. This study aimed to investigate the impact of surgical management for relapse after conversion hepatectomy in IU-CRLM.
The NICE study is a prospective, multi-site study to train and validate a blood-based, glycoproteomic test for the early detection of advanced adenoma and colorectal cancer by collecting blood samples and associated relevant clinical information from average-risk participants who undergo routine screening colonoscopy as well as participants undergoing colonoscopy for surveillance or diagnostic indications
This is a single blind, case control, multicenter study jointly developed by Zhongshan Hospital of Fudan University, Shanghai Public Health Clinical Center, Shanghai Xuhui Central Hospital, Qingpu Branch of Zhongshan Hospital Affiliated to Fudan University, and Shanghai Singlera Genomics Company. The enrolled population will include positive group, precancerous lesions and healthy control group, which is expected to enroll 2,430 participants. The primary objective is to establish molecular testing methods for non-invasive screening and early diagnosis of digestive system cancers through ctDNA methylation and mutation, cfDNA and ctDNA fragment size, and end motif based model (for esophageal, gastric, colorectal cancer), and through ctDNA methylation detection, ctDNA low-pass WGS, miRNA7 and CTC detection and analysis technology based model (for hepatocellular carcinoma). The sensitivity and specificity of the models in cancer early detection will be evaluated.
Colonoscopy completion by caecal intubation seldom represents a significant effort for the endoscopist. In this situation, additional techniques are necessary to achieve this goal: patients' manual abdominal compression, postural changes, and endoscopist relay. To date, no tool allows colonoscopy technical difficulty grading. This study pursues to describe the frequency of additional techniques for caecal intubation in a large sample of Argentinians in different centres who undergo colonoscopy for attending purposes, to develop a novel score for assessing colonoscopy technical difficulty.
Colorectal cancer (CRC) is the second most commonly occurring cancer worldwide. Thirty-five percent of CRC patients are diagnosed at stage II/III, and their outcome differs even if they are in the same stage. Previous study found that the microenvironmental collagen is associated with tumor progression and metastasis. Whether tumor microenvironmental collagen signature is associated with colorectal cancer prognosis still remains unknown. We hypothesize that the tumor microenvironmental collagen signature of colorectal cancer is associated with prognosis.
Immunotherapy improved efficacy and survival in selective patients with metastatic colorectal cancer (mCRC), however, limited data revealed the landscape of immunotherapy efficacy. What's more, potential markers have not been comprehensively evaluated to identify responding patients to further improve efficacy.The investigators conducted a single-arm study to investigate the efficacy of combination immunotherapy in patients with mCRC, and the combined regimen is determined by the physician in charge.
