Filter by:The goal of the study is to determine, using a choice-based approach, what messages (pulled from various online sites) people find more and less persuasive and shareable on the topic of colorectal cancer screening. As a secondary goal, the study is interested how various information behaviors, such as people's self-reported seeking of health information and encountering of health information, demographic variables, individual difference variables, and message exposure associate with their intentions to adhere to recommended colorectal cancer screening guidelines from the National Cancer Institute. The study is interested at differences specifically among Black and White Americans of recommended screening age (45-74).
Liver metastases are present in 15-25% of patients with colorectal cancer at the time of diagnosis of the primary tumor, which is defined as synchronous liver metastases. Treatment for the potential cure of this disease includes surgical resection of both the primary tumor and liver metastases. The liver first approach was described by Mentha for patients with asymptomatic rectal tumors with with initially unresectable or borderline resectable liver metastases. There is little data in the scientific literature on how many patients scheduled for this strategy complete both surgeries and/or undergo the full chemo/radiation therapy.
The aim of this study is to demonstrate the feasibility, surgical, and oncologic outcomes of laparoscopic right hemicolectomy with CME and CVL compared to open surgery.
This 12-week, exercise study will assess the feasibility of a home-based high-intensity interval training (HIIT) program among colorectal cancer survivors and explore the impact of home-based HIIT compared to a standard home-based moderate-intensity continuous aerobic exercise program on physical outcomes linked with survival from colorectal cancer and surrogate blood markers of colorectal cancer recurrence. HIIT is a type of aerobic exercise that includes short bursts (i.e. 1-4 minutes) of vigorous exercise followed by longer periods of moderate to lower intensity exercise (i.e. 1-10 minutes). Participants in this study will be randomly assigned into a personalized home based exercise program - either high-intensity interval training (HIIT) or moderate-intensity continuous aerobic exercise (MICE). This pilot study will provide us with preliminary evidence for a larger trial aimed to compare the effectiveness of these two different types of home-based exercise programs on physical outcomes linked with survival, quality of life, and surrogate blood markers of colorectal cancer recurrence.
Serrated polyposis syndrome (SPS) is the most common colorectal polyposis syndrome and is characterized by the combination of large and/or numerous serrated lesions (SLs) throughout the colorectum. SLs are classified into sessile serrated polyps (SSP) with or without dysplasia, hyperplastic polyps (HP) and traditional serrated adenomas (TSA). In 2010 the World Health Organization (WHO) defined this syndrome by any one of the following conditions: criterion I, at least 5 SLs proximal to the sigmoid colon with 2 or more of these being >10mm in size; criterion II, any SLs proximal to the sigmoid colon in a first-degree relative with SPS; criterion III, more than 20 SLs of any size distributed throughout the colon. It has been demonstrated that 11.8-28.5% of patients with SPS present with colorectal cancer (CRC) at diagnosis. Tandem colonoscopy studies have demonstrated that a significant number of lesions are missed during conventional colonoscopy. This finding is even more evident when focusing SLs where a 31% miss rate has been reported. SLs are often overlooked due to their typical appearance: flat morphology, similar colour to the surrounding mucosa, subtle and indistinctive borders. Chromoendoscopy (dye spraying onto the surface of the colon) enhances the detection of subtle and flat polyps in the colon. Until the date no studies have assessed the use of dye-based chromoendoscopy in SPS patients. The aim of this trial was to evaluate the usefulness of panchromoendoscopy with indigo carmine for the detection of polyps in the colon in patients with SPS. Secondary aims were to estimate the SLs and adenoma miss rates in these patients. Patients were randomized in a 1:1 distribution to one of the two arms of the study by a list of random numbers distributed by the coordinator center. After randomization, patients were submitted to tandem colonoscopies by the same endoscopist: - In group A (HR-WLE) the first inspection was on high-resolution white-light endoscopy from the cecum/ileo-colonic anastomosis to the rectum, followed by a second inspection also on HR-WLE. - In group B (HR-CE) the first inspection was on HR-WLE from the cecum/ileo-colonic anastomosis to the rectum, followed by a second inspection with panchromoendoscopy. For this, the lumen was sprayed in a segmental fashion using 0.4% indigo carmine delivered via a specially designed dye spray catheter (Olympus PW-5V1) or via the accessory channel with a 50cc syringe filled with indigo carmine and air. After allowing a few seconds for the dye to settle onto the mucosal surface, excess pools of indigo carmine were suctioned and the mucosa was then scrutinised. Time to withdrawal from the cecum was measured using a stopwatch excluding time needed for polypectomy and biopsies. Lesions detected during each inspection were described and then removed. Size (measured in comparison with an open biopsy forceps), morphology (using the Paris classification), location and polypectomy technique were recorded before removal. Histology was used as gold standard.
EMI-137 in laparoscopic colonic resections is a single-centre stage IIa developmental study. Ten adult participants with a diagnosis of colon adenocarcinoma undergoing laparoscopic colonic will be recruited to the trial. Participants will receive a single intravenous dose of the IMP - EMI-137 1 to 3 hours before surgery. The ability of EMI-137 to produce visible intra-operative fluorescence of primary colon cancer and lymph node metastases will be explored and evaluated.
Small growths detected in the colon (polyps) during a colonoscopy may or may not have the potential to develop into cancer. However, since visual inspection alone cannot separate all potentially harmful polyps from harmless ones, the standard approach is to remove them all for histological lab examination, exposing patients to risk of injury and putting a significant demand on hospital resources. An accurate method of determining polyp type during endoscopy would enable the clinician to only remove potentially harmful polyps. A new endoscopic optical imaging probe (OPTIC), which analyses how light interacts with tissue, is proposed to do this. The probe is contained within a normal endoscope and uses white light and blue/violet laser light to illuminate the tissue. The reflected and fluorescent light emitted, along with normal colour pictures of the polyp surface, are measured and recorded to quantify specific characteristics of each type. Optical measurements of polyps detected in endoscopy clinics at Imperial College Healthcare NHS Trust will be analysed to determine if the signal can be used to differentiate different polyp types.
Right-sided colonic cancer is treated with right-sided colectomy, predominantly performed as minimally invasive surgery with extracorporeal anastomosis (ECA). In recent years a new technique with intracorporeal anastomosis (ICA) has emerged and it is thought that ICA is less invasive and thereby has the potential to improve the postoperative course of right colonic cancer patients. The objective of this study is to compare robotic right colectomy with either ICA or ECA in a randomized controlled setting.
Background. Enhanced Recovery After Surgery (E.R.A.S.) programs are now widely accepted in colonic laparoscopic resections because of faster recovery and less perioperative complications. Objective. Aim of this study is to assess safety and feasibility of discharging patients operated on by laparoscopic colectomy on Post Operative Day 2 (POD 2), so long as the first flatus has passed and in the absence of complication-related symptoms. Design & Settings. Non-inferiority, open-label, single center, prospective, randomized study comparing "Ultra" to Classic E.R.A.S. with discharge on POD 2 and 4 respectively. Patients. 765 patients with resectable non metastatic colonic cancer were analyzed: 384 patients were assigned to "Ultra" E.R.A.S. and 381 to Classic E.R.A.S. Main Outcome Measures. Demographics, clinico-pathological, ASA class and morbi-mortality, along with surgical complications, re-operation and readmission rate were recorded and compared. Primary end-point was mortality; secondary end-points were morbidity, re-admission and re-operation rate. Limitations. It is a single center experience; it is not double-blind, with the intrinsic risk of intentional or unconscious bias; exclusion criteria because of "non compliance" may be considered arbitrary.
In the proposed study, investigators will conduct a 90-day dietary intervention study in human subjects. Thirty individuals at risk for adenomatous colon polyp formation will be randomized to receive a calcium and multi-mineral-rich natural product (Aquamin) or a comparable level of calcium alone. There will also be a placebo group. Prior to ingesting the study agents and following the course of treatment, colonic biopsies will be obtained by sigmoidoscopy and quantitatively examined for markers of growth and differentiation. In this study, metabolomic and microbial profiles will also be generated from fecal and colon mucosal samples taken at baseline and study endpoint.
