Filter by:This study will evaluate safety, pharmacodynamics and biomarkers of subcutaneous (SC) DK210(EGFR) given as monotherapy and in combination with immunotherapy, chemotherapy or radiation.
Constitution of a biobank of tissues, whole blood and plasma samples and stools to identify markers associated with treatment response, postoperative morbidity including neuro-cognitive and mood complications and prognosis of Inflammatory Bowel disease or colorectal cancer.
The overarching aim is to study the coproduction of personalised care in a digital age by seeking to improve the experience of care and personalised care and support planning for people who live with and beyond colorectal cancer. This study will assess digital health contributions to personalised care and explore how to improve the quality of collaborative digital care planning in cancer services. The electronic holistic needs assessment (eHNA) developed by Macmillan Cancer Support (macmillan.org.uk/healthcare-professionals/innovation-in-cancer-care/holistic-needs-assessmen t/sign-up-to-ehna) will be used as a case study to help advance this aspect of healthcare improvement studies. The primary objective is to gain a better understanding of how personalised care and support planning in the form of the eHNA and consultation works (or not) from the perspectives of people who are living with and beyond colorectal cancer, and clinicians. The secondary objectives are to: i. identify what good practice looks like for digital personalised care and support planning in a specific tumour group (colorectal) and at a point in the cancer pathway (within 31 days of diagnosis) ii. explore if the ARC framework can be used to inform personalised cancer care and support planning The research will review current practice and focus on identifying what good looks like for digital cancer care planning. It will go on to explore how what we know about LWBC can be used to inform the co-design of digital care planning that better supports personalised long-term cancer care. From the outset, this early work will help to inform future issues around generalisability and scaling-up.
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.
Patients with stage Ⅰ colorectal cancer or stage Ⅱ colon cancer usually have a good prognosis and are not recommended to receive adjuvant chemotherapy after radical surgery. With the advances in liquid biopsy technology, detection of circulating tumor DNA (ctDNA) can effectively identify early-stage cancer patients with minimal residual disease (MRD) after surgery. According to the growing number of MRD studies in solid tumor, colorectal cancer patients with ctDNA-MRD detection have a poor clinical outcome and are likely to relapse within two years. This study aims to assess the efficacy of adjuvant chemotherapy with capecitabine plus oxaliplatin (CAPEOX) compared with conventional observation in MRD-positive patients with stage I colorectal cancer and clinically low-risk stage II colon cancer.
Colorectal cancer tissue sections were obtained according to the inclusion criteria. The formalin was used to immersed all cancer specimens. And tissues were cut to 5 μm thickness and placed on glass slides before staining. Endogenous peroxidase activity was inhibited and blocked by de-paraffinizing, rehydrating, and using 5% bovine serum albumin at 37ºC for 30 min. The treated sections were incubated with anti-FOS (promab 30360) at 4ºC overnight and washed three times with PBS. After that, it is required that incubation with secondary anti-peroxidation sunflower at 37ºC for 30 minutes. After washing three times again with PBS, the sections were developed in diaminobenzidine and microscopic images were made by light microscopy.
The objective of this Study is to collect, process, and transfer biologic samples such as blood and/or tissue biopsies to determine the concordance of detected alterations obtained through liquid biopsy analyses compared to next generation sequencing of time-matched or archival tissue specimens from individuals with advanced solid tumors. Examples of locally advanced and metastatic tumors include stage III and IV cancers (ex. lung, breast, all gastrointestinal malignancies, all gynecologic malignancies, prostate cancer, head and neck tumors, soft tissue cancers, and melanoma). These specimens will be analyzed for diagnostic purposes and research (either by Labcorp/OmniSeq or to a third-party recipient designated by Labcorp/OmniSeq). Labcorp/OmniSeq may transfer the specimens and data to its clients, including commercial, academic or non-profit research institutions; or alternatively, may retain the specimens in its repository for future research use at the sole discretion of Labcorp/OmniSeq and or assignees. Labcorp/OmniSeq will maintain all detailed clinical information including demographic data (de-identified), ethnicity, disease state, stage (radiological, pathological and clinical-whichever is relevant).
To identify Black individuals who are eligible for genetic testing through trusted community organizations, and to connect Black individuals and their families to genetic testing and counseling so that they can know their cancer risk and how to decrease it.
This is a 3-year pragmatic, randomized clinical trial among average-risk patients at diverse primary care practices who are overdue for colorectal (CRC) screening. This project aims to evaluate the effect of a centralized program that includes direct outreach to patients and visit-based, clinician directed nudges facilitated by the electronic health record (EHR) with follow-up text messaging on the uptake of CRC screening. The primary outcome is CRC screening completion at 3 years. Patient and clinician factors impacting the experience and effectiveness of the intervention will be explored through surveys and qualitative interviews.
The goal of this observational population-based cohort study is to investigate the clinical characteristics and outcomes of children and adolescents with primary gastrointestinal malignancies registered in the publicly available Surveillance, Epidemiology, and End Results (SEER) 17 database during 2000-2019.
