Filter by:I plan to investigate the value of video-based feedback in endoscopic training - specifically, the role of terminal video feedback as compared to usual concurrent feedback on cold snare polypectomy technique in trainees, using Direct Observation of Polypectomy Skills (DOPyS) competency score. I have focused the study on the competency of cold snare polypectomy for subcentimeter polyps. The majority (>75%) of colon polyps are smaller than one centimeter. Cold snare polypectomy has been shown, and recommended by the American Society for Gastrointestinal Endoscopy (ASGE), to be an effective removal technique. However, its widespread use and moreover, its teaching to trainees is lacking. It takes time and resources to learn and teach endoscopic techniques. Our study will hope to identify a mechanism through video-based feedback that could help to improve the translation of the training of polypectomy skills to its actual performance, and to accelerate the learning curve.
To study whether or not total mediastinal lymph node dissection in conjunction with pulmonary metastasectomy from colorectal cancer is associated with improved survival compared to pulmonary metastasectomy only.
Endoscopic diagnosis of lateral spreading tumours (LST) with submucosal invasion is important in guiding the treatment strategy. The use of advanced imaging is not standard clinical practice in China. A clinical trial is now under way comparing the accuracy of narrow band imaging (NBI), endoscopic ultrasonography (EUS) and magnifying chromoendoscopy (MCE) for the diagnosis of LST with submucosal invasion.
This is a single-arm, open-label, multi-center early phase II study. This proof of concept study will investigate whether the combined use of local tumor ablation/radiation plus immunomodulating drugs may induce a significant immune response in patient with incurable liver metastases from colorectal cancer (CRC) (+/- limited extrahepatic disease) being stable or in partial remission after completion of 4-6 months first line systemic therapy. The primary objective of the study is to show an overall response rate of lesions not treated by ablation/radiotherapy including the extrahepatic lesions (according to iRECIST criteria) higher than 10%. With the continuation of first line systemic treatment, no further responses are expected. Secondary objectives are: - To establish the feasibility and safety of the combined treatment modalities; - To study the impact of the local technique (RFA/Radiotherapy) on the results; - To investigate biomarkers to predict response to the combined treatment
The goal of this study is to find the best ways to increase colorectal cancer (CRC) screening.
This is a single arm open label pilot phase II trial of Regorafenib PO plus 5-FU/LV infusion in 15 mCRC patients who progressed on prior Regorafenib monotherapy as well as 5-FU containing chemotherapy combinations.The study will enroll mCRC patients with prior progression on standard multi-agent combination chemotherapy and progression on regorafenib monotherapy.
This is a Phase II randomized, double-blind, placebo-controlled trial of neoadjuvant artesunate given orally as a dose of 200 mg once a day for 14 days to patients with histologically confirmed Stage II/III colorectal cancer (CRC) awaiting surgical treatment with curative intent.
Different subtypes of serrated lesions have been recently described. Among them, both sessile serrated polyp/adenoma (SSP/A) and traditional serrated adenoma (TSA) could have malignant potential through the serrated pathway or CIMP. These lesions, as a potential source of interval cancer, should also be considered in colorectal cancer (CRC) population-based screening programs. It is believed that this new described pathway could be responsible for up to 30% of all CRC. Unlike the traditional adenoma, serrated lesions are difficult to diagnose because of their particular endoscopic appearance and their still unclear histological criteria. Furthermore, they have specific molecular changes and, through them, they could evolve into CRC faster than the adenoma. The real prevalence of the serrated lesions and their specific risk for developing new synchronous/metachronous lesions, or even malignancy, remains unknown. For all these reasons, we don't know if these patients could constitute a different CRC-risk group and if specific recommendations are needed during their follow-up. This is a prospective longitudinal study developed within the framework of the CRC-screening program in the Valencian Community (Spain). We expect to include a total of 700 individuals who will be followed during 10 years. In our study, we will collect epidemiologic variables related to the patient, variables related to all the polyps, and mutational (BRAF, KRAS, MSI), and CpG-island methylation status of serrated lesions. Strict endoscopic and histological criteria will be applied for the diagnosis of serrated lesions. All lesions detected at the index colonoscopy and during follow-up will be evaluated. The purpose of this study is to correlate epidemiologic data, histological characteristics and the molecular profile of the serrated lesions with findings during follow-up, in order to define stratified groups according to their risk of developing new lesions or CRC in the future.
The primary objective is to prove non-inferiority of thermal ablation compared to hepatic resection in patients with at least one resectable and ablatable colorectal liver metastases (≤3cm) and no extrahepatic disease.
Cytokine-induced killer cells (CIK) is an auxiliary antitumor treatment. The investigators aim to evaluate the clinical efficacy of chemotherapy combined with CIK in the treatment of postoperative colorectal cancer patients. And to provide useful reference for the clinical application of CIK in colorectal cancer patients.
