Active clinical trials for "Colorectal Neoplasms"

The aim of this study is to identify more persons with advanced neoplasia in the current national CRC screening, by adding data on family history of CRC (using a validated online questionnaire) to FIT. In addition, the aim is to identify those persons and their family members who should not be participating in a FIT based screening but receive surveillance colonoscopies instead, because of a familial CRC syndrome. It is aimed to increase detection without affecting participation, thereby increasing the yield of screening.

Regional lymph node metastasis is a major determinant of local recurrence and overall survival rates in patients with colorectal cancer. Because of the poor prognosis associated with the presence of lymph node metastasis, stage III colorectal cancer patients should receive adjuvant treatment with chemo and / or radiation therapy according to the site of tumor. Several authors have investigated the use of revealing solutions for lymph node clearance in colorectal cancer. Most studies comparing conventional histopathological specimen examination to any lymph node clearing technique showed that the use of revealing solutions increases the mean number of lymph nodes harvested, usually in a statistically significant manner. It is still controversial the impact of the use of revealing solutions for upstaging of lymph node status and consequently for the indication for adjuvant therapy. Therefore will be conducted a randomized clinical trial to compares the performance of GEWF and Carnoy solutions for the histopathological examination of patients with colorectal cancer. The aim of this study is to determine the lymph node revealing solution with the best performance (increase in the mean number of lymph node harvested and lymph node upstaging) in patients with colorectal cancer.

The purpose of this study is to compare the additional diagnostic yield obtained by performing NaviAid™ G-Eye procedure vs. the diagnostic yield obtained by performing standard colonoscopy procedure.

The purpose of this study is to increase colorectal cancer screening by implementing a community-wide shared decision-making (SDM) intervention, which embeds shared decision making within clinical practice and also uses an extensive community engagement campaign. The investigators hypothesize that colorectal cancer screening adherence will be higher in the intervention group (participating communities) compared to the usual care control group (non-participating comparison communities).

The purpose of this study is to determine whether the presence of pathogenic Escherichia coli in colon is associated with psychiatric disorders.

This is single-center, prospective, non-randomized study

The investigators propose to develop, implement, and evaluate a novel Colorectal (CRC) screening patient navigator program for patients with Mental Health (MH) and /or Substance Use Disorder (SUD) receiving care at Massachusetts General Hospital Charlestown. The study will involve randomly assigning eligible patients to early intervention or usual care/delayed intervention groups. The investigators believe this random assignment is ethical because Patient Navigation (PN) is an extremely limited resource, and all patients identified as eligible could not be contacted by the navigators in a short period of time. Thus the investigators will randomly assign access to PN during the study period, and then allow all patients to be navigated and screened after the study period is over. As a result, all eligible patients will be referred for PN, but the timing of the referral will be randomly assigned.

Physician recommendation has been shown to be one of the most significant predictors for colorectal cancer (CRC) screening. This study aims to identify the amount of parents of internal medicine residents at NYU who are eligible for CRC screening but have not received it. Investigators will perform an intervention and quantify the amount of parents eligible for CRC screening after the intervention. This study will entail sending 2 brief surveys (one before the intervention and one after) which determine if the parents of the residents are eligible for CRC screening. The intervention will be asking the residents with eligible parents to have a discussion with their parents about CRC screening options and to address their concerns. Investigators will provide a one page document the residents can give their parents as a reference as part of the intervention.

The purpose of this research study is to compare a new educational material to another widely available educational brochure. The goal is to see if the new educational material will change knowledge and behaviors about colorectal cancer and colorectal screening.

The purpose of this study is to conduct 4 focus groups and recruit for 12 participants per focus group to explore community members' views about colorectal cancer screening (CRCS) processes and perceived benefits and impediments, what information they believe should be communicated, communication preferences (style, tone) and perceptions of screenings.
