Colorectal cancer (CRC) is a leading cause of death in the Western world. It can be effectively prevented by removal of pre-malignant polyps during colonoscopy. Large (≥20mm) non-pedunculated colorectal polyps (LNPCPs) represent 2-3% of colorectal polyps and require special attention prior to treatment. If submucosal invasive cancer (SMI) is suspected, careful decision making is required to exclude features which unacceptably increase the risk of lymph node metastases and render local treatment (endoscopic) non-curative. Such patients require a multi-disciplinary approach and consideration of surgery +/- systemic therapy. Unfortunately, current classification systems are complex, require extensive training and technology not available in the majority of non-tertiary hospitals. They are therefore underused leading to incorrect decision making and negative patient outcomes (e.g. piecemeal resection without the chance of endoscopic cure or unnecessary further procedures in referral centres with resultant surgery anyway or surgery for benign disease). Studies from the field of psychology show that humans are often capable of making correct decision based on their Blink (first) impression. It is also suggested that this Blink impression is based on experience and training. This might suggest that experienced or specialist endoscopist are better at diagnosing SMI within colorectal polyp at Blink impression. The investigators hypothesize that by training the Blink impression, endoscopist of varying experience are able to detect cancer within LNPCPs. This can be proven by assessing the Blink impression of endoscopist of varying experience regarding the presence of SMI within LNPCPs. Increasing the accuracy of the determination of SMI within colon polyps would directly translate into improvements in patient care and outcome. For example, if SMI is present and is not suspected, patients may undergo unnecessary endoscopic procedures for an LNPCP which will eventually require surgery anyway (inconvenience, delayed correct treatment). If the incorrect technique is performed in the context of superficial SMI, adequate assessment of complete excision or extent and type of SMI may not be possible and a patient who would otherwise have been cured may require surgery anyway (under-treatment, below standard of care outcome, delay to treatment). Conversely, if SMI is suspected in its absence patients may undergo unnecessary surgery, increased healthcare spends and mortality (over-treatment, unnecessary risk). If the presence of SMI could be accurately determined in real-time using endoscopic imaging, delays to treatment, over-treatment and the associated morbidity for patients could be avoided.
The PROTEOS study is an randomized controlled, open label, parallel-group, multi-centre and multicounty interventional study to assess the acceptance and implementation of Compact Protein, a low volume, energy dense and high protein oral nutritional support in clinical practice according to the ESPEN guidelines in colorectal and lung cancer patients undergoing chemo(radio)- or immunotherapy treatment.
This retrospective study reviewed 3,144 patients who underwent surgery for colorectal cancer. This study was designed to comprehend the clinicopathological characteristics associated with individual codon-specific KRAS mutations in colorectal cancer.
The aim of this study is to examine the effect of NLP techniques on stoma compliance and quality of life in patients with stoma. The study will be conducted using a prospective randomized controlled single-blind clinical trial model. The research will consist of patients with temporary or permanent colostomy/ileostomy, who are hospitalized in Mersin City Training and Research Hospital. Research data will be obtained with demographic questionnaire, Adjustment Scale for Individuals with Ostomy and Stoma Quality of Life Scale. Analysis of the study data will be done through the IBM SPSS Statistics 26 package program. While evaluating the study data, frequencies (number, percentage) for categorical variables and descriptive statistics (mean, standard deviation) for numerical variables will be given. Statistical significance in the analyzes will be interpreted at the 0.05 level.
The proposed study is a randomized controlled pilot trial designed to assess the effectiveness and acceptability of a proactive screening outreach program on colorectal cancer screening rates on eligible patients in the Flatbush Family Health Center medical practice.
APOLLO (Acute PresentatiOn of CoLorectaL Cancer: an internatiOnal snapshot) is an international, multi-centre, prospective observational study which will address this need and aims to describe the operative and non-operative management of emergency presentations of colon and rectal cancer in an international cohort.
Screening for colorectal cancer can reduce its incidence and mortality but is a complex, error-prone process. The value of screening with colonoscopy is in removing pre-cancerous polyps that increase one's risk for future cancer. Abnormal results are common, and failure to receive recommended follow-up undermines the benefits of screening, violates the trust that patients place in their providers, and increases medicolegal risk. This proposal seeks to ensure that the foundation of safety systems, the recommendations for the follow-up interval reflect current guideline recommendations and are accurately updated. Specifically, the investigators will implement and evaluate in a randomized trial a new colonoscopy result letter as part of usual care that automatically updates the recommended follow-up interval in the patient's health record compared to the current result letter format.
In Pakistan, due to the lack of a National based cancer registry exact number of CRC cases is unknown. However, minimal data that is present in literature shows an increase in CRC cases with a concerning increase in incidence in younger age groups11. This makes it pertinent to understand current pattern of CRC and its risk factors from a local perspective. This will direct future strategies in an attempt to reduce the incidence and mortality associated with CRC in our general population.
The investigators hope that this project will determine if the Endocuff device is a useful adjunct during colonoscopy by optimizing polyp detection and eliminating the need for the painful rectal retroflexion. As such, by improving polyp detection and eliminating the need for rectal retroflexion, it will directly reduce the likelihood of colon cancer and improve patient comfort respectively.
