Active clinical trials for "Colonic Neoplasms"

Surgery is the primary treatment for colon cancer. However, the rate of recurrence or metastasis in colon cancer can be as high as 30%, even in stages 1 and 2 . Most colon cancer-related deaths are caused by metastatic disease . Many patients with colon cancer harbour micrometastases and disseminated tumour cells at the time of surgery . Whether the micrometastases develop into clinically significant metastases depends on the immune system's ability to eradicate them.The aim of the study is to declare the effect of epidural-intravenous based anesthetic technique on anti-tumor immunity and in comparison to epidural inhalational based anesthetic technique in patients undergoing open surgical resection of colon cancer.

This pilot clinical trial studies short-infusion ziv-aflibercept in treating patients with metastatic colorectal cancer receiving combination chemotherapy. Ziv-aflibercept may stop the growth of colorectal cancer by blocking blood flow to the tumor. Giving the drug over a shorter infusion time may result in improved efficiency and patient satisfaction.

This study is a multi-site randomized, controlled trial testing the effect of a combined intervention that includes a colorectal cancer (CRC) screening decision aid plus patient navigation in a diverse, primary care patient population in clinical sites in North Carolina and New Mexico. Our primary aim is to determine the effect of the intervention on CRC screening completion six months after the index visit among all enrolled participants and among Latinos. Secondarily, we will determine how this intervention affects screening-related knowledge, self-efficacy, intent, and clinical communication, and examine whether these factors mediate the effect of the intervention on screening test completion. Lastly, we will explore whether insurance status, ethnicity, and patient language preference moderate the effect of the intervention on screening.

The aim of this study is to evaluate FUSE-colonoscopy in terms of feasibility and its possible additive contribution in the detection of important lesions, namely polyps and cancers, compared to the standard "forward-viewing" approach, with and without the addition of the right-colon retroflexion technique, in a series of patients undergoing back-to-back screening or surveillance colonoscopies in a randomized fashion.

This randomized clinical trial focused on activating the patient to ask their health care provider for a colorectal cancer screening test to improve screening rates for colorectal cancer. The patient activation intervention may increase information seeking, number of screening tests ordered and number of completed screening tests for colorectal cancer.

The purpose of this research study is to explore ways to improve appropriate colorectal cancer (CRC) screening in the elderly by attempting to target screening in those most likely to benefit and avoiding screening in those least likely to benefit.

The investigators believe that glucagon therapy will have a positive impact on key parameters of colonoscopy such as cecal intubation time, withdrawal time, total procedure time, adenoma detection rate, endoscopist's assessment of the difficulty of the procedure, patient comfort, and patient's willingness to undergo a repeat colonoscopy.

The following project deals with a Danish multicenter trial that evaluates the value of Laparoscopic Ultrasound examination (LUS) in laparoscopic surgery for colon and rectum cancer (CRC). The project "The value of laparoscopic ultrasound in patients undergoing laparoscopic resection for colon and rectum cancer. - A prospective randomized trial" is part of a ph.d- study at the University of Southern Denmark in collaboration with several surgical departments at hospitals in Southern Denmark. The primary purpose is to investigate whether the use of laparoscopic ultrasound examination (LUS) will change the stage of the tumor, lymph node and metastasis (TNM stage) and the surgical approach in patients undergoing laparoscopic surgery for colorectal cancer (CRC). As a secondary objective; an evaluation of the use of LUS will change the treatment strategy for the individual patient with CRC. As an other objective we wants to investigate whether the use of contrast enhanced ultrasound examination in connection with LUS procedure increases the number of detected liver metastases.

Ancillary Aim #1 We will evaluate intervention effects by comparing binary outcomes for screening (yes/no) in the primary SOS study. In this aim, we propose to calculate actual screening rates by use of time-to-event analyses (also known as survival analysis). The outcome variable of interest is the first time since randomization to have CRCS, either based on FOBT, FS, or CS. Knowing screening rates will not only enable us to make comparisons between groups, but also over time. Ancillary Aims #2 and #3 We will recruit additional participants for two ancillary study aims. First, we will enroll patients age 50-74 years using the same criteria as for the primary SOS study, which includes neither history of colorectal cancer nor evidence of life-limiting disease. Participants who return the questionnaire, consent and considered eligible will be randomized to receive one of three different at-home fecal test kits. The kits will be returned to the GH centralized laboratory, and participants will be informed about lab results using standard GH pathways. Participants who have a test-positive will receive a series of two follow-up surveys (first at 1-2 weeks post result and second at 4-months post result). A comparison group of test-negative results will be matched based on selected criteria, and this group will also receive the follow-up surveys. Participants at both time intervals who do not return the survey via mail will be called and if available, administered the questionnaire via phone.

A double center study to evaluate the safety and efficacy of the Aer-O-Scope in traveling through the colon in low risk subjects.
