This clinical trial implements research strategies to increase colorectal cancer (CRC) screening rates among low income and ethnic minority groups. CRC is the second most common cause of cancer mortality in the United States and disproportionately burdens low income and ethnic minority groups. Fecal immunochemical testing (FIT) is a test to check for blood in the stool. A brush is used to collect water drops from around the surface of a stool while it is still in the toilet bowl. The samples are then sent to a laboratory, where they are checked for a human blood protein. Blood in the stool may be a sign of colorectal cancer. Despite its potential for reducing CRC incidence and mortality, screening remains woefully underutilized. There is an unmet need for practical and effective programs to improve CRC screening rates. By implementing a culturally-tailored screening CRC program that supports providers and clinic staff to encourage eligible patients to complete FIT, researchers hope to reduce cancer disparities among low-income and ethnic groups and increase the CRC screening rate, which will help providers find CRC sooner, when it may be easier to treat.
Approximately two-thirds of all colorectal cancer patients undergo surgery with the aim of curing them. However, despite the surgery, 20-25% of them experience relapse. It is possible to reduce the risk of relapse with chemotherapy, but as chemotherapy is associated with significant side effects, it is only given to patients at high risk of relapse. Currently, the risk is assessed based on an examination of the removed tumor tissue. In a previous research project, blood samples were taken after patients' surgery and examined for the presence of circulating tumor DNA (ctDNA). When cancer cells in solid tumors die, they release DNA, which can be detected in the blood. DNA in the blood has a half-life of less than 2 hours, so if ctDNA is found in a blood sample taken, e.g., 14 days after surgery, the patient most likely still has cancer cells in their body. The results show that if a patient has ctDNA in their blood after surgery, the risk of relapse is high. The presence of ctDNA in the blood has the potential to be a better indicator of the risk of future relapse than the tumor examination used today. Therefore, ctDNA analysis has the potential to become a marker that will be used in the future clinical setting for monitoring colorectal cancer. The overall objective of this study is to confirm that ctDNA found in a blood sample after intended curative treatment for CRC is a marker of residual disease and risk of recurrence and is applicable in clinical practice.
The purpose of this study is to compare the effect of face-to-face training of general practitioners on the implementation of a shared decision (in the context of colorectal cancer screening), versus current practice (i.e. without training in the patient-centered approach).
The intrinsic connection between inflammation and tumor promotion is well characterized and is a key pathogenic event in patients with colorectal cancer (CRC), the second most common cause of tumor-related death in western countries. Environmental factors and chronic inflammation represent the major causes of intestinal carcinogenesis. In fact, patients suffering from inflammatory bowel diseases, including Crohn's disease and Ulcerative Colitis (UC), have high risk of developing colitis-associated CRC with poor prognoses. Therefore, targeting the cancer-associated inflammation may offer new avenues for cancer treatment. In fact, several anti-inflammatory drugs, have been used for prophylaxis and have shown efficacy in contrasting cancer, despite various adverse side effects. Thus, there is an urgent need to discover novel cancer-associated mechanisms to develop alternative therapies that may reduce aberrant inflammatory responses without interfering with physiological defenses against infection and functional anti-tumor immunity. A novel approach promoting anti-tumor immunity has been recently proposed after the discovery of potent, endogenous, specialized pro-resolving mediators (SPMs), including lipoxins, resolvins, protectins, and maresins, mainly derived from omega-3 polyunsaturated fatty acid (PUFA) docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) via COX, LOX and CYP450 pathways, mediated by MFSD2A. Due to the potent bioactivity of SPMs in resolving inflammation and because of the correlation between inflammation and cancer, the roles of these lipid mediators have attracted great attention for their potential therapeutic role in cancer treatment, including CRC. Nevertheless, the understanding of the endogenous mechanisms that limit the inflammatory response during CRC development is incomplete and requires further investigation. Based on the preliminary results indicating that dysfunctional MFSD2A-dependent pro-resolving pathways may foster CRC development, the investigators aim to define the functional role of MFSD2A in orchestrating pro-resolving pathways in the intestinal endothelium of metastatic and not metastatic CRC patients. This is a cross-sectional single-center observational study involving patients with CRC. The investigators will enroll 15 patients with colorectal cancer (CRC) stratified by tumor stage (T0 / T1-T4, M0 / M1, N0 / N1 / N2) undergoing surgery in the Gastroenterology and Digestive Endoscopy unit within Gastro Center (IRCCS Ospedale San Raffaele). Human Intestinal Microvascular Endothelial Cells (HIMEC) will be generated from each sample of cancer surgical specimens, while the healthy cells will be derived from the healthy margins of the colorectal resection of the same CRC patients. MFSD2A will be overexpressed or silenced and the investigators will evaluate its biological effects in both tumor-derived HIMECs and healthy tissue-derived HIMECs through transcriptomics and lipidomics analysis. The investigators will also exploit a possible novel therapy based on the delivery of MFSD2A encoding plasmid-conjugated liposomes.
Identify and test thresholds, specificity and sensitivity for a potential cancer associated biomarker protein, FGF19, (and associated markers) for detection in human blood in the blood of breast and colorectal in cancer patients, and see if occurs at higher rates than healthy controls
This study aims to better understand the cause of colorectal cancer and how to find the best treatment for Hispanic patients with colorectal cancer. The genetic information in the blood and tissues may explain why patients who have the same type of cancer and receive the same treatment do not always have the same results. By combining genetic (certain qualities or traits passed from parents to offspring) information with clinical data, such as the responses of different kinds of cancers to different treatments, this study could lead to more knowledge about why certain cancers occur and why they respond differently to treatments. Information gathered from this study may help researchers match treatments to the genetics of each patient and the genetic changes in their tumor. This approach is known as personalized medicine.
The goal of this single-arm study is to evaluate the efficacy and safety of Envafolimab combined with Trifluridine/Tipiracil and Bevacizumab in the treatment of metastatic colorectal cancer patients who are refractory or intolerant to standard therapy.
The goal of this clinical trial is to test a new smartphone-based program designed to help African American men get screened for colorectal cancer (CRC). The main question it aims to answer is: ° Are African American men who complete the smartphone-based program more likely to get screened for colorectal cancer than men who do not? Participants will: - Complete a baseline survey asking about their colorectal cancer screening history and their thoughts and beliefs about colorectal cancer and the medical system. - Be randomized to receive the new smartphone-based program or to receive text messages containing colorectal cancer education materials designed by the Centers for Disease Control (CDC). The new program sends text messages with information about colorectal cancer. Some of these text messages have links to videos that try to help men overcome anything that may stand in the way of getting screened. - Complete a follow-up survey 6 months after the baseline survey. This survey will ask the same questions as the baseline survey. - A medical records review will be conducted at 6 months to verify whether participants received a colorectal cancer screening test during the study period. Researchers will compare participants who receive the new smartphone-based program to participants who receive the CDC information. The goal is to see whether the smartphone-based program increasing screening more than standard educational materials available on the internet.
