Filter by:Background: Sweden has a long tradition of organized national population-based screening programs. Participation rates differ between programs and regions, are relatively high in some groups, but lower in other. To apply an equity perspective on screening, it is desired that individuals make an informed decision on knowledge rather than ignorance, misconceptions, or fear. Decision Aids (DAs) are set to deliver information about different health care options and to help individuals make visible values connected to the options available. DAs are not meant to guide individuals to choose one option over the another. The advantage of an individual Decision Aid (iDA) is that individuals gain knowledge on cancer and screening entering one webpage with possibility to communicate with health professionals and thereafter make their decision regarding participate. The primary objective is therefore to develop and implement a web-based iDA for individuals invited to cancer screening in Sweden. The secondary objective is to evaluate the implemented web-based iDA. Methods: This study has an evaluative approach with both a process-, an implementation and an outcome evaluation. Multiple methods will be used including patient reported data, focus group discussions and individual interviews using the think aloud technique. The project is based on the framework from The International Patient Decision Aid Standards (IPDAS) and the proposed model development process for DAs as presented by Coulter et al. Individuals aged 23-74, including women aged (the cervical- and breast- and bowel cancer screening module) and men aged (the bowel cancer screening module), will be included in the developmental process. Efforts will be made to recruit participants with disabilities, who live outside society and who are foreign born. Discussion: To the best of our knowledge the present study is the first aiming at developing an iDA for usage in Swedish context, The iDA is intended to contribute so that individuals invited to screening base their decision on knowledge and with a clear picture of their values and preferences, rather than ignorance, misconceptions, or fear. Furthermore, the iDA is expected to increase knowledge and raise awareness in general about cancer and cancer screening in society.
The three main pathways of colorectal carcinogenesis are chromosomal instability, microsatellite instability (MSI) (15% of colorectal cancers =CRCs) and CpG island methylator phenotype (CIMP). MSI CRCs are associated with a better prognosis after curative surgery than CRCs without microsatellite instability (MSS). In contrast, MSI CRCs do not appear to benefit from adjuvant 5-FU chemotherapy, unlike patients with MSS CRCs. Nevertheless, the benefit of adjuvant chemotherapy with FOLFOX seems to be retained. The identification of prognostic markers in this subgroup of patients is therefore essential to decide on adjuvant chemotherapy, the efficacy of which is currently debated in MSI CRC. To date, there are very few data concerning metastatic MSI CRC. Metastatic forms are rare (about 5% of metastatic CRCs), but are thought to be associated with chemoresistance and poor prognosis. Nevertheless, data are very sparse and there are no data regarding the use of modern chemotherapies and targeted therapies in metastatic MSI CRC. Thus, it is important to characterize the chemosensitivity of metastatic forms. Clinical predictors of recurrence after curative CRC surgery are known but have only been studied in MSI CRC retrospectively. Similarly, many molecular and immunohistochemical factors, prognostic or predictive of response to adjuvant chemotherapy, have been recently identified in CRC (KRAS, BRAF, TP53, PI3KCA mutations, CIMP phenotype, SMAD4, immune response...). Most of these markers have been studied in all CRCs, but not specifically in the MSI CRC subgroup. All these prognostic and/or predictive biomarkers need to be better characterized in a large cohort of MSI CRCs.
The current study is to investigate the safety and efficacy of fruquintinib combined with HAIC in patients with advanced colorectal liver metastases who have failed second-line systemic standard treatment, in order to provide more survival opportunities for the second progression of advanced colorectal liver metastases.
AIO-KRK-0420 NeoBRAF is a single arm, multicenter, phase II trial with neoadjuvant encorafenib, binimetinib and cetuximab for patients with BRAF V600E mutated/pMMR localized colorectal cancer.
To evaluate the effectiveness and accuracy of the ctDNA dual-target test kit in a large case-control cohort for the detection of colorectal cancer and advanced adenomas.
Patients with colorectal cancer will be recruited to undergo vitamin D supplementation in the peri-operative period. Vitamin D levels (25OHD) will be measured to assess response to supplementation.
The overall goal of this educational program was to increase colorectal cancer screening (CRCS) in men and women who attend Federally Qualified Health Centers (FQHC) in Puerto Rico. FQHCs, referred to in Puerto Rico as "Clínicas 330", are ideal settings to implement innovative approaches to increase CRCS because they serve primarily low-income patients who typically have lower rates of screening. The goal of this study, is to develop and evaluate the impact of a clinic level intervention on increasing CRCS among low-income Puerto Rican men and women aged 50-75, who have either never been screened for colorectal cancer, or are under-screened according recommended guidelines. To evaluate the delivery of the CRCS education program we used a group randomized controlled trial that provided data to determine the effectiveness of the CRC intervention program compared with usual practice (no intervention).
Compare the efficacy and safety of endoscopic resection a full thickness (EFTR) with Full Thickness Resection Device (FTRD) System versus endoscopic submucosal dissection (ESD) in the treatment of Laterally Spreading Tumor Non Granular Type (LST-NG), "no lift" lesions colon and residual / relapse on scars from previous resections endoscopic colon. The dimensional cut off of these lesions is ≤30mm
This project is the first application, which is applied as a single center project and applied according to the screening quantity. This project is a multi-omics approach to explore biomarkers associated with prognosis after secondary radical resection of recurrent and metastatic colorectal cancer. Main research objectives: 1. To detect DNA mutation and methylation in tumor tissues by NGS detection technology (the methylation dimension should be detected in adjacent tissues at the same time), and to explore specific molecular markers related to prognosis; 2. Using NGS test technology of blood in patients with preoperative and postoperative blood ctDNA mutations and methylation double dimension testing, respectively, to explore the preoperative and postoperative ctDNA mutations and the correlation between methylation status and recurrence, including but not limited to predict patients with recurrence of sensitivity, specificity, positive predictive value, negative predictive value and recurrence warning time and other indicators. Main contents: This study intends to include single site for the first time/organ metastasis after radical treatment and surgical indications again in patients with colorectal adenocarcinoma (including but not limited to spread to the liver, lung metastasis, peritoneal metastasis, lymph node metastasis and other organ metastasis), collected in patients with preoperative peripheral blood and tissue samples, tissue adjacent to carcinoma and postoperative peripheral blood, NGS detection technology was used to detect DNA and mutation in the relevant samples, combined with clinical treatment and prognosis information of patients, and then explore biomarkers for predicting recurrence risk.
