Filter by:The aim of this explorative phase II clinical trial is to establish the safety and efficacy of intratumoral influenza vaccine in patients with colorectal cancer, as an additive treatment prior to intended curative surgery.
Background Laparoscopic resection is the treatment of choice for colorectal cancer. Rates of conversion to open surgery range between 7% and 30% and controversy exists as to the effect of this on oncologic outcomes. The objective of this study was to analyze what factors are predictive of conversion and what effect they have on oncologic outcomes. Material & Methods From a prospective database of patients undergoing laparoscopic surgery between 2000 and 2018 a uni- and multivariate analyses were made of demographic, pathological and surgical variables together with complementary treatments comparing purely laparoscopic resection with conversions to open surgery. Overall and disease-free survival were compared using the Kaplan-Meier method.
This work is an implementation science study that examines different aspects of implementing a single intervention. The intervention consists of asking community health centers to implement an outreach strategy to screen patients for colorectal cancer and for social determinants of health in community health centers at the same contact point. These are both clinical targets that the CHCs feel that their patients need and want to offer at a higher rate. The intervention consists of outreach to patients in need of colorectal cancer screening (CRC) to offer fecal immunochemical test (FIT) screening and screening for social determinants of health (SDOH). In this implementation science study, the intervention is an evidence-based intervention being implemented in real-world clinical practice. The intervention is the outreach to offer FIT and SDOH, conducted by clinic staff. Both evidence-based screening activities-FIT and SDOH screening-are used in the practices included in the study but pairing them is intended to increase efficiency and patient-centeredness by addressing health related social needs that may impact patients' ability to engage in cancer screening. The study aims to test the effect of implementing the intervention on clinical and process outcomes. Clinical outcomes are CRC screening and SDOH screening. Analysis of process outcomes includes measuring what organizational factors influence implementation.
We aim to perform a register-based, observational cohort study to investigate whether it is safe to delay start of treatment with a curative intention after a colorectal cancer diagnosis. Our hypothesis is that delaying start of treatment until 4-8 weeks is as safe as starting treatment within four weeks after a colorectal cancer diagnosis.
This is a non-profit phase II, open-label, single-arm study of cetuximab plus avelumab in patients with RAS WT mCRC treated in first line with chemotherapy in combination with an anti- EGFR drug that have had a clinical benefit (complete or partial response) from treatment.
This is a prospective, multi-endoscopist, single center, clinical study at tertiary referral center that addresses an important current challenge in the prevention of colorectal cancer (CRC), namely, how to improve the complete removal of CRC precursors. This study will observe the potential benefit of specific polypectomy technique in conjunction with a systematic submucosal injection prior to the polyp resection. This study will evaluate the completeness and incompleteness of the resection of colorectal neoplastic polyps during the procedures.
In this evaluation, 4 different versions of letters are being sent with mailers promoting colorectal cancer screening with an at-home test. The researchers hypothesize that the use of behavioral nudges in the message should lead to increased colorectal cancer screening (either with the at-home test or a colonoscopy).
Colorectal cancers are the third most common type of cancer in the world. Peritoneal carcinomatosis and intraabdominal acid development occur in advanced stages of colorectal cancers. It is known that the immune system plays an important role in tumor development or tumor eradication. Among the mechanisms of escape from the immune system, changes in the tumor microenvironment play an important role. Immune checkpoints are molecules that have become popular especially after the Nobel Prize in 2018, and are important in revealing the relationship between cancer and the immune system. In our study, it is aimed to evaluate whether there is a difference in intraabdominal ascites fluid immune checkpoints level in patients with advanced colorectal cancer patients compared to patients without malignancy.
Colorectal cancers are the third most common type of cancer in the world. Peritoneal carcinomatosis and intraabdominal acid development occur in advanced stages of colorectal cancers. It is known that the immune system plays an important role in tumor development or tumor eradication. Differentiation of T cells towards Th2 and regulatory T cells is also reported to be effective in tumor progression. Among the mechanisms of escape from the immune system, changes in the tumor microenvironment play an important role. The role of regulatory T lymphocytes, a subgroup of T cells that play a regulatory role by suppressing the function of other T lymphocytes, is to reduce the chronic immune response against viruses, tumors and patients's own antigens. The common feature of all Tregs is that they secrete one or more anti-inflammatory molecules such as IL-10, TGFβ or IL-35. High levels of Tregs have been found in peripheral blood, tumor tissue and lymph nodes in patients with malignancy. In our study, it is aimed to evaluate whether there is a difference in intraabdominal ascites fluid T helper cytokine levels in patients with end-stage colorectal cancers compared to patients without malignancy.
The aim of this study was to compare the willingness to use and attitude towards VC amongst both patients with colorectal cancer and healthcare providers during follow up care. Second, to determine the satisfaction with the quality of the healthcare provider and the usability of the used VC technology. 50 patients will be asked to choose between video consultation or face-to-face contact at the outpatient surgical clinic.
