Filter by:The purpose of this research protocol is to compare open versus laparoscopic right colectomy (according to the CME technique of complete mesocolic excision) for right colon cancer. This study will be designed as a prospective randomized controlled trial. The comparison of the two techniques will include endpoints regarding the quality characteristics of the specimens and the oncological results. In addition, the effectiveness of the two methods will be evaluated in terms of the early and late postoperative period.
This study is designed as a multi-center, randomized, double-blind, placebo-controlled trial. Subjects in the intervention group will be treated with XLJDOD compound granule. Subjects in the control group will be treated with placebo (XLJDOD mimetic agent).
Retrospective and prospective observational study of patients undergoing advanced pelvic oncological resection for maligancy including multi visceral resection, beyond TME resection and sacrectomy/flap reconstruction/urinary reconstruction at Glasgow Royal Infirmary. Goal is to study and report outcomes for patients to characterise and understand major complications, natural history of resectional patients and identify areas for future interventional study.
The goal of this clinical trial is to determine the safety and efficacy of IP-001 for intratumoral injection administration following thermal ablation of a solid tumor.
This protocol seeks to develop a colonoscopy training program in Nigeria in order to increase the number of health care providers proficient in colonoscopy. The goal is to improve capacity for screening and early diagnosis of colorectal cancer (CRC) by training and expanding the healthcare workforce that is competent in endoscopy techniques. The project has three components, a needs assessment, simulation training, and training on live patients. The first part of this project determines the number of providers and endoscopy procedures currently performed in Nigeria, as well as patient access to facilities that have colonoscopy capabilities, through a mixed methods approach. Surveys, focus in-depth interviews with key stakeholders, and use geographic information system (GIS) modeling technology will be employed to perform a needs assessment. The second component of this project investigates whether a locally developed low fidelity (LF) simulation colonoscopy training model is an effective teaching, training, and assessment tool for skill acquisition and confidence compared to a high-fidelity (HF) colonoscopy model. The third component of this project is training healthcare providers on real patients who have an indication for colonoscopy. This project seeks to build capacity for endoscopy services in order to increase capacity for screening and early diagnosis of CRC. At the end of the project, it is expected the number of providers trained to perform colonoscopy in a resource limited setting like Nigeria will increase.
This is a community-based study requiring participant-self-enrollment, that can help to increase the rates of genetic testing among the family members of people who have been diagnosed with a hereditary cancer syndrome. The two main factors in this study are the IGNITE-TX intervention (website and navigator) and the free genetic counseling and testing. The IGNITE-TX Intervention is an innovative multi-modal intervention, with two components: a) interactive web "IGNITE-TX Hub" and b) genetic family navigators.
The aim of this study is to evaluate the safety and efficacy of neoadjuvant treatment with pembrolizumab before colonic resection in patients with early-stage (I-III) deficient mismatch repair (dMMR) colon cancer (CC).
The long-term study objective is to develop optimized nutritional therapies for surgery and test them in clinical practice. This pilot study will test a microbiome-optimization diet in colorectal cancer surgery patients. The study hypothesizes that the Bacterial Intestinal Gut Modification Around Cancer Surgery (BIG MACS) Diet will provide participants with increased microbiota accessible carbohydrates (MACs) to support the microbiome and improve outcomes.
Patients with gastric or colon cancer with peritoneal carcinomatosis will receive a biopsy of the tumor during their primary curative surgery. The operation is performed according to standard and includes resection of the primary tumor and any metastases and followed by HIPEC (Intraperitoneal hyperthermic chemoperfusion) according to the respective hospital standard. Organoid cultures from the biopsies are established in the research laboratory. Various chemotherapeutic agents are tested on these tumor organoids in the laboratory and the tumor organoids are analyzed in detail with regard to genetic alterations in order to find alterations that can be addressed, if necessary, by means of targeted drugs against peritoneal carcinomatosis.
Anastomotic leak (AL) is one of the most feared complications after colon cancer (CC) surgery. The incidence varies according to the studies, the definition used and the location of the excised segment. In some of the series described, AL incidence have hardly changed, despite the evolution of the technique and technological improvements. The leak rate obtained in the only Spanish prospective multicenter observational study at national level was 9% (ANACO study). The aim of the present study is to determine the current rate of AL in our country, 10 years after the ANACO study, to determine if there has been any evolution and to analyze the factors associated with it. For this purpose, AL is defined with the same criteria as in the first study, as leakage of luminal contents through the junction between two hollow visceras, diagnosed radiologically (radiography with soluble enema or CT with collection adjacent to the anastomosis), clinically (extravasation of luminal contents or gas through the wound or drainage), endoscopically or intraoperatively. To compare AL rates throughout this decade, a 60-day follow-up will be performed, the same as in the ANACO study. As a modification respect to the ANACO study protocol, the aim is to analyze the possible influence of AL and perioperative intra-abdominal infection on short-term oncologic prognosis, with a one-year follow-up. This question has hardly been studied in prospective multicenter studies to date. The variables to be collected are divided into demographic (information about the hospital center, patient comorbidities), diagnostic variables (analytical values, diagnostic reason, neoadjuvant, localization, TNM), surgical variables (type of surgery, preparation, intention, intraoperative findings and complications, type of resection and anastomosis), admission (AL, other complications), histology, 60-day follow-up (AL, readmissions), one-year follow-up (readmissions, local recurrence, peritoneal and distant recurrence). Patients included in the study must be >18 years old undergoing oncologic surgery for CC located 15 cm above the anal margin, with preoperative histological confirmation or with endoscopic suspicion of infiltrating lesion or with radiological suspicion in the context of urgent surgery. Intestinal continuity (anastomosis) should be reconstructed and a derivative stoma should not be associated in the same surgery. According to ANACO data and follow-up times according to the primary objective (AL) at 60 days and the secondary objective (oncologic prognosis) with annual follow-up, inclusion will be carried out until the 1628 individuals required according to the sample size calculation performed are included.
