Active clinical trials for "Colorectal Neoplasms"

The burden of colorectal cancer (CRC) is unequal among various populations within the United States. This inequality is most notable among African Americans, who exhibit the highest CRC mortality of all US populations. This study aims to evaluate a community-based intervention to educate, assess risk, and overcome barriers to screening among African Americans who are 45 years or older with no personal history of CRC, adenomas, or inflammatory bowel disease and have no family history of CRC. Barriers being assessed include: Need for establishing care with primary care physician, need for financial assistance, need for reminder calls, need for transportation, need for appointment coordination, and need for education about colonoscopy preparation and procedure

The short perioperative period (days to weeks around surgery) is characterized by stress-inflammatory responses, including catecholamines (CAs, e.g., adrenaline) and prostaglandins (PGs, e.g., prostaglandin-E2) release, and induce deleterious pro-metastatic effects. Animal studies implicated excess perioperative release of CAs and PGs in facilitating cancer progression by affecting the malignant tissue, its local environment, and anti-metastatic immune functions. Congruently, animal studies conducted by the investigators indicate that combined use of the beta-adrenergic blocker, propranolol, and the prostaglandins inhibitor, etodolac - but neither drug separately - efficiently prevented post-operative metastatic development. Two recently conducted clinical trials, conducted by the investigators, in three medical centers in Israel, recruiting breast (n=38) and colorectal (n=34) cancer patients, assessing the safety and short-term efficacy of perioperative propranolol and etodolac treatment. Drugs were well tolerated, without severe adverse events. Importantly, molecular/biological analyses of the excised primary tumor indicated that drug treatment caused promising anti-metastatic transformations, as well as improvements in immune and inflammatory indices. These included (i) decreased tumor cell capacity to migrate, (ii) reduced pro-metastatic capacity of the malignant tissue, and (iii) improvement in immune infiltrating into the tumor (Paper published in Clinical Cancer Research, 2017). Herein, the investigators propose to conduct a double-blind placebo-controlled two-arm Phase II clinical trial in 200 colorectal cancer patients undergoing curative surgery in Israel. A perioperative 20-day drug treatment will be initiated 5 days before surgery. Primary outcomes will include (i) 3-year disease-free-survival (DFS), and 5-year overall survival (OS); and (ii) biological markers in blood samples, and in the excised tumor tissue. Secondary outcomes will include safety indices and psychological measures of depression, anxiety, distress, and fatigue

This trial will determine the clinical effectiveness of polygenic risk score testing among patients at high genetic risk for at least one of six diseases (coronary artery disease, atrial fibrillation, type 2 diabetes mellitus, colorectal cancer, breast cancer, or prostate cancer), measured by time-to-diagnosis of prevalent or incident disease over 24 months.

IMPROVE-IT2 is a randomized multicenter trial comparing the outcomes of ctDNA guided post-operative surveillance and standard-of-care CT-scan surveillance. The hypothesis of this study is that ctDNA guided post-operative surveillance combining ctDNA and radiological assessments could result in earlier detection of recurrent disease and identify more patients eligible for curative treatment.

Positron labeled camptothecin based PET imaging is a new imaging technique that uses positron isotopes such as 68Ga/64Cu for PET/CT (MR) imaging. It is expected to have significant clinical significance in staging and detecting primary and metastatic head and neck cancer, oral cancer, and colorectal cancer tumors.

This pilot study will explore the preliminary efficacy of a colorectal cancer (CRC) screening intervention delivered by virtual health assistants (VHAs). Participants will include 750 African American patients in the US between the ages of 45 and 75 recruited through Qualtrics panels. The main research question is: How does the integration of different levels of dialect density of the linguistic features of African American English (AAE) influence the perceived credibility of a Black VHA. Four types of VHAs will be presented to our patients: a VHA with Standardized American English (SAE) linguistic features, a VHA with a low level of African American English (AAE) linguistic features integrated, a VHA with a high level of African American English (AAE) linguistic features integrated, and a text-only control condition. Survey questions will be used to obtain credibility judgments about VHAs post-interaction.

The purpose of this research study is to examine whether adding walnuts to your diet can have a beneficial effect on the gut bacteria population, inflammatory markers in the blood, and the tissue that lines the inside of the colon.

Approximately 42% of American adults are obese, and this condition is strongly related to the development of colorectal cancer. Innovative lifestyle strategies to treat obesity and reduce colorectal cancer risk are critically needed. This research will demonstrate that time-restricted eating, a type of intermittent fasting, is an effective therapy to help obese individuals reduce and control their body weight and prevent the development of colorectal cancer.

This study collects information to provide a model for how to rapidly adapt and scale-up multilevel interventions through clinic-health plan partnerships to reduce the burden of colorectal cancer (CRC) on the United states population. This study may improve colorectal cancer screening rates, follow-up colonoscopy, and referral to care in rural Medicaid patients.
